Technical field

The present invention relates to a kneading apparatus for kneading a material to be kneaded having fluidity. More specifically, the present invention relates to a kneading apparatus for kneading a kneaded material by changing the cross-sectional shape of the kneaded material itself by passing the kneaded material through a deformed passage having a changed cross-sectional shape. Background art

Conventionally, there are various materials that require kneading. The ingredients are, for example, the kind of ingredients such as “udon” and “soba” that are loved as foodstuffs, and the ingredients of kneaded products, as well as mortar and concrete.

Materials to be kneaded that require such kneading often exhibit more favorable properties or better properties and physical properties as they are kneaded. Therefore, in the case of such a material to be kneaded, a sufficient kneading operation is required in advance.

By the way, the conventional kneading methods include mixers (kneading devices) such as an arm type, a chi type, and a roll type depending on the kneading method. Since these are performed mechanically, all of them are suitable for kneading a large amount of materials. I have.

Such a conventional kneading apparatus is certainly effective depending on the material to be kneaded. However, it is known that it is not very efficient when examined from the viewpoint of energy and time required for kneading.

For example, a research report by Yoji Akao, Hisakazu Shindo, and Hern 'Hernan, "Synthesis of Mixed Systems and Formation of Their Optimum Layers" (Journal of the Society of Powder Technology, Vol. 19, No. 11 (1992) )} Is the feed layer that is the fastest to reach the complete mixing state (optimum layer) is a layered mixture obtained by folding the basic model of moving mixing, that is, compressing, bisecting, and adding half It is described as corresponding to an i-shaped mixture obtained by repeating the above operation.

In that regard, traditional methods such as homemade bread are used to compress and elongate the dough, fold it back and stack it, and further reduce it by £ Ε and elongate it. It can be seen that the kneading method of exposing is extremely efficient. If the folding and compression processes were performed 30 times, it would be equivalent to kneading 2 to the power of 30 = 1 billion times. Here, if the kneading method of compressing with three or four layers before compression is performed, in the above example, the value corresponding to 2 to the 30th power is 3 to the 30th power or 4 to the power. It can be assumed that the efficiency is improved to the 30th power. On the other hand, as described above, in the case of mixers (kneading devices) that have been widely used, such as arm type, chi type, roll type, etc., all of them have many mechanically movable parts. Damage is also likely to occur. Furthermore, the equipment itself is relatively expensive.c This point is particularly important in the field of construction and civil engineering where mortar or concrete containing particles such as fine aggregate or coarse aggregate is used as the material to be kneaded. Notable. Disclosure of the invention

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and the kneading is performed by allowing the material to be kneaded to pass through a deformed passage whose cross-sectional shape gradually changes in the longitudinal direction by free fall due to its own weight. An object of the present invention is to provide a kneading apparatus that mechanically kneads materials efficiently.

The present invention is a kneading apparatus, and employs the following configuration in order to solve the above-described technical problem. That is, in the kneading apparatus of the present invention, an inlet portion is formed at one end and an outlet portion is formed at the other end, and the cross-sectional shape continuously changes from the inlet portion to the outlet portion, and extends substantially vertically. A plurality of deformed passages; and a merging dividing means provided between the inlet and the outlet of each deformed passage, for merging and dividing the material to be kneaded passing through each deformed passage. In the deformed passage, the extending direction of each deformed passage is changed to “ョ:” so that there is no straight through passage extending from the inlet portion to the outlet π portion. It is characterized in that two or more materials to be kneaded are introduced from the inlet portion, and are kneaded by free fall and passing through the respective deformed passages toward the outlet portion.

The kneading apparatus of the present invention is composed of the essential components described above, but is also established when the components are concretely as follows. The concrete component is that the kneading device is configured by connecting a plurality of elements almost vertically, and It has an inlet end, an outlet end, and a plurality of the deformed passages from the inlet end to the outlet end. The arrangement pattern of the person channels of the respective deformed passages formed at the inlet end is different from the arrangement pattern of the outlet portions of the respective deformed passages formed at the outlet end. Further, each of the elements is connected to the outlet of the adjacent element in close contact with the I end and the inlet end, and the inlet of each of the deformed passages at the connection side end of each of the elements. The connecting part between the part and the outlet part constitutes the merging division means.

In the element, rectangular openings are arranged side by side as an arrangement pattern of the entrance portions of the respective deformed passages, and JT square openings are arranged vertically as an arrangement pattern of the exit portions. At the same time, the kneading device is composed of at least two types of different communication modes between the respective inlet portions and the respective outlet portions of the respective deformed passages, and the kneading device alternately vertically connects the different types of the elements. It is composed.

Further, a hopper used for supplying the material to be kneaded is connected to the inlet end of the element located at the uppermost stage among the plurality of elements.

Further, in the present invention, it is possible to configure an element for a kneading apparatus by connecting two different types of elements to form a set. Each element as a set includes an inlet end, an outlet end, and a plurality of deformed passages from the inlet end to the outlet end, each of the deformed passages having a cross section from the inlet to the outlet. The shape is continuously changed, and the configuration of the communication between the respective inlet portions and the respective outlet portions of the respective deformed passages of the respective elements and the manner of changing the cross-sectional shape are different from each other.

In this case, the arrangement pattern of the inlet portion of each deformed passage formed at the inlet end of each element is different from the arrangement pattern of the outlet portion of each deformed passage formed at the outlet end. Is done.

According to the kneading apparatus having such features, when the material to be kneaded is introduced into the internal deformed passage from the upper inlet end of the kneading apparatus in which the plurality of deformed passages are arranged substantially vertically, the kneaded material has its own weight. Fall in each deformed passage by free fall. Since the cross-sectional shape of each deformed passage continuously changes in the longitudinal direction, the material to be kneaded falling in the deformed passage is subjected to compressive deformation and a deforming action based on the compressive deformation, and is kneaded.

In addition, while the material to be kneaded falls through this deformed passage, The materials to be kneaded passing through the respective deformed passages merge, and are again divided (divided) into the respective deformed passages and fall, preferably by repeating this process. Will be. In this case, the extending directions of the deformed passages are mutually changed so that there is no straight through passage from the inlet to the outlet of the deformed passages. Does not fall without undergoing the kneading action. Thereby, the kneading action can be exhibited as designed.

Generally, by connecting a plurality of elements in the vertical direction so as to be stacked, this proportional flow action can be necessarily obtained. As described above, the element includes an inlet end, an outlet end, and a plurality of deformed passages extending from the inlet end to the outlet end, and the arrangement of the inlets of the deformed passages formed at the inlet end. The arrangement pattern of the pattern and the exit of each deformed passage formed at the exit is different from each other. Such elements are closely adhered to the exit and entrance of adjacent elements. If they are connected together, the connection between the entrance and the exit of each deformed passage in each element serves as the junction dividing means.

In addition, when rectangular openings are arranged side by side as an arrangement pattern at the entrance of each deformed passage, and when elements having rectangular openings arranged vertically are used as an arrangement pattern at the exit, In addition, at least two types of elements having different communication modes between each inlet and each outlet of each deformed passage are manufactured, and a kneading device is formed by alternately connecting these different elements vertically. If it is configured, the number of straight through-holes (linear communication sections) from the upper end of the kneading device [: 1 end to the lower exit end is reduced or eliminated, and the material to be kneaded falling from above is dropped. only _three kneading effect of the greatly improved, since only have to connect to fabricate Ereme down bets, also contribute to the production of the kneading instrumentation kappa.

Further, in the present invention, the kneading apparatus can also be constituted by a minimum unit number of elements that connects two different types of elements to form one set. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, the kneading apparatus of the present invention will be described in more detail with reference to an embodiment shown in the drawings. FIG. 1 schematically shows a kneading apparatus 10 according to an embodiment of the present invention. The kneading apparatus 10 according to this embodiment is basically configured by alternately connecting four kinds of two elements 11a and 11b in total.

Explaining the specific configuration of each element 11a and lib, first, one type of element 11a has square end portions as shown in Fig. 2, and these end portions have Is formed with a flange F for connecting the elements to each other. A plurality of bolt holes f1 are formed in the flange F, and the adjacent elements are connected to each other by bolting their ends using the bolt holes f1. The element 11a has two deformation passages 12 and 13 arranged side by side in the same direction. As shown in Figure 2, at the negative end of this element 1 la. A partition wall 14 is provided at the center so as to form a vertically long opening on the left and right. Becomes the inlet section 1 2 &, 3 a of each of the two deformed passages 1 2, 1, 3, and the other end of the element 11 a has a central portion so as to form a horizontally long opening vertically. A partition wall 15 is provided. The horizontally elongated upper and lower openings become the outlets 1 2b and 13 b of the two deformed passages 12-13. That is, the partition wall 14 at the entrance end of the element 1 ta and the partition wall 15 at the exit end are arranged so as to be 90 degrees different from each other. Therefore, the array pattern of the two artificial portions 12a and 13a of the deformed passages 12 and 13 is such that rectangular openings are formed side by side, and the two outlet portions 1 2b and 1 3 The arrangement pattern b is formed by arranging rectangular openings vertically.

Explaining the specific shapes of the deformed passages 12 and 13, the cross-sectional shape of each of the deformed passages 12 and 13 is from the inlets 12 a and 13 a to the outlets 12 b and 13 b. It is changing continuously. Regarding the aspect of the change, the cross-sectional area at any position of each of the deformed passages 12 and 3 is the same from the inlets 12a and 13a to the outlets 13a and 3b. Only the shape of the cross section changes continuously.

In other words, the entrances 12a and 13a are rectangles that are long in the X direction, and the cross section of the middle part between the I-parts 12a and 13a and the exits 12b and 13b is The outlets 12b and 13b are formed so as to be rectangular in the Y direction perpendicular to the X direction in the Y direction. The lengths of the deformed passages 12 and 13 are the same. Therefore, the material to be kneaded passing through each of the deformed passages 1, 2 and 13 has its cross-sectional shape gradually changed from a rectangle longer in the X direction to a square, and then gradually changed to a rectangle longer in the Y direction. Will be done.

In this element 11a, the inlet I2a located on the left side in FIG. 2 and the outlet 12b located above communicate with each other through the deformed passageway 12, and the person located on the right side has the ί section. 13 a and the outlet 13 b located below communicate with each other through the deformed passage 13.

Next, another type of element 1 1b is shown in Fig. 3. It is basically the same as the above-mentioned element 11a, but this element 1 1b In Figure 3 The inlet section 1 2a located on the left side and the outlet section 1 2b located below communicate with each other through the deformed passageway 12, and the inlet section 13 a located on the right side and the outlet section located above 3 b Communicate with each other via the deformed passage 13. That is, the Ereme down DOO 1 lb is, _c that different from the communication mode between the inlet and the outlet of the element's 1 1 a and each of the modified passages

Furthermore, this element lib has a different relationship between the respective inlet portions and the respective outlet portions of the respective deformed passages, and thus the cross-sectional shape of each of the deformed passages 12 and 13 varies. I have. This is because the extending direction of each deformed passage of the element 11a: the torsion direction is different from the extending direction (twist direction) of each deformed passage of the element 1 lb. Based on

FIG. 4 shows a state in which such two types of elements 11a and lib are connected alternately. That is, the two types of elements 11a and lib described above are connected to the exit end of one element 11a and the entrance end of the other element 11b by a flange F They are connected to each other by bolts.

Therefore, at the connection between the two types of elements 11a and lib, the force at the exit 1 2b of the deformation passage 12 in one element 11a and the deformation in the other element 1b One half of the inlet 12 of the passage 12 and the inlet of the other deformed passage 13] communicate with the half of the other deformed passage 13] 3a, and the outlet 13 of the deformed passage 13 in one element 11a. b communicates with the other half of the inlet〗 2 a of the deformed passage 12 in the other element 11 b and the other half of the inlet 13 a of the other deformed passage 13 Therefore, half of the material to be kneaded that has passed through each of the deformed passages 12 and I3 in one element 11a is placed in each of the deformed passages 12 and 13 of the other element 11b. By entering, they will substantially merge. However, when looking at the material to be kneaded passing through one of the deformed passages, it will be split into two halves at the connection between the two elements.

Therefore, the outlets and the inlets of the deformed passages formed at the outlet 侧 end, which is the connection portion of the two elements 11a, lib, and the artificial end, join the material to be kneaded. This constitutes a dividing means. If such elements 11a and 11 are connected alternately in series as shown in FIG. 1, a means for converging and dividing the material to be kneaded is formed at each connection. A kneading method using the kneading apparatus 10 in such an embodiment will be described below with reference to FIG. In addition, this process diagram shows how the cutting of the material to be kneaded lii when two elements 11a and 11b are connected (two stages) is shown in each element 11a and 11b. The model of the area of the inlet side end, the middle part, and the outlet side end is shown.

As can be clearly understood from FIG. 5, first, the material to be kneaded is put into a hopper 16 installed at the upper entrance end of the uppermost element 11a. If two or more kinds of the materials to be kneaded are kneaded, it is preferable that a predetermined amount of each kind of the materials to be kneaded is alternately put into the hopper 16 in a layered manner and dropped. Needless to say, the most preferable mode suitable for the properties of the material to be kneaded can be adopted as a method of charging the material to be kneaded by various experiments.

The material to be kneaded introduced into the hopper 16 enters the two deformed passages 12 and 13 at the inlet end of the first stage element Ija, and is eventually divided into two, A and B. Is done. Each sectional shape of the divided material to be kneaded was the _c then are both long awe way shape in the X direction, in the middle portion of the first stage, the mixing materials A, B cross-sectional shapes are both changed into a square shape In addition, at the end of the first stage on the exit side, the shape changes to a rectangle elongated in the Y direction by 90 degrees from the longitudinal direction X on the entrance side.

Accordingly, the cross-sectional shape of each of the materials A and B to be kneaded changes as follows: a rectangle long in the X direction and a square—a rectangle long in the Y direction. In this changing process, the inner wall surfaces of the deformed passages 12 and 13 receive a continuous compression action. As a result, a continuous convection phenomenon occurs in the material to be kneaded itself, particularly in the radial direction of the cross section, whereby the first kneading action is performed.

Next, the partition wall 1.5 at the entrance end of the second stage element 11b intersects the partition wall 14 at the exit end of the first stage element at a right angle. Therefore, the materials A and B to be kneaded coming out of the outlet end of the element 11a of the second stage are divided into right and left as shown in Fig. 5, and are divided into A, B and A'Β. Divided. Then, the kneaded material AB flows in each of the deformed passages 12 and 13. That is, at the inlet end of the 1-lb element of the second stage, the material to be kneaded. A part of λ and Β merges in each of the deformed passages 12 and 13, respectively, and the material to be kneaded in each of the passages. In Both cross-sectional shapes are rectangles that are long in the X direction.

Next, in the middle part of the second stage, the cross-sectional shape of the material A B to be kneaded is changed into a square shape as a whole, and at the outlet end, both are changed into a rectangle long in the Y direction. Also in the second stage, the materials A and 'B to be kneaded change from a rectangle long in the X direction—a square—a rectangle long in the Υ direction. In the course of the change, the inner wall surfaces of the deformed passages 12 and 13 receive a continuous compression action. As a result, a continuous convection phenomenon occurs in the material to be kneaded itself, particularly in the radial direction of the cross section, whereby the secondary kneading action is performed.

Although not particularly shown in the third stage, at the inlet end of the third stage, a virtual line X1 is added to the final kneaded material at the outlet end of the second stage shown in FIG.左右左右分割分割 Α · Β Thereafter, kneading is performed in the same manner as in the first and second stages.

Incidentally, in this embodiment, Ereme down bets is connected alternately different two Ereme emissions Bok 1 1 a, 1 1 b a as described above, which is shown in _c Figure 2 explaining the reasons When 11a is drawn II from one end in each deformed passage, as shown in Fig. 6, the part excluding the shaded line appears as a straight through path, that is, a straight through path ₍ this is described above). As described above, the right inlet 12a at the inlet end communicates with the upper outlet 12b at the outlet end, and the population on the left at the inlet end is 3a. It is natural that the force that communicates with the lower outlet part 13b at the end, and the area where they respectively partially overlap, allows the outlet part to be directly seen from the inlet part. When viewed from the longitudinal direction of 11a, the inlets I2a., 13a and the outlets 12b, 13b It is difficult for the material to be kneaded to be deformed in the passage portions existing in the respective partially overlapping regions. Therefore, it cannot be simply stated, but the material to be kneaded with low viscosity may be less susceptible to deformation.) Even if a plurality of elements 1 la of the same shape are connected, the end state when the deformed passages were glancing from no different state shown in FIG. accordance connexion, kneading effect even when the Ereme down bets 1 1 a of the same shape connecting a plurality is not so good _c while Ereme For the element 11b, the same theory as nil described for the element 11a is used. The region where the entrances 12a and 13a and the exits 12b and 13b overlap due to bending is a portion excluding the shadow line shown in FIG. This is different from element 11a in that the right inlet 12a at the inlet end communicates with the lower outlet 12b at the outlet end and the left inlet 12b at the inlet end. It is evident from the fact that the inlet 13a communicates with the upper outlet 13b at the outlet end.

Therefore, assuming that these two types of elements 11a and 11b are connected as shown in Fig. 4, if the deformed passage is opened from the end on the inlet side, Fig. 6 and Fig. becomes Netayo state, this result inlet portion ₃ trough Ukoto no longer be able to face the outlet portion from the material to be kneaded entering from the inlet portion, flowing to [II section exit at Tokoroisu preparative rate And as a result, the kneading effect is further enhanced.

It has been found that such a kneading apparatus 10 is very useful, for example, for kneading the core material of the mouth wall dam and for kneading the mortar and the coarse aggregate as a pretreatment in producing a concrete. Generally, the particle size of the coarse aggregate mixed in the concrete is 80 mm, 40 mm and 25 mm. It is preferable to determine the width (indicated by L in Fig. 6). In this case, the relationship between the population width L and the particle size of the coarse aggregate used is L≥3 x (particle size of the coarse aggregate used .: That is, the particle size of the coarse aggregate used is When the lengths are 25 mm, 40 mm, and 80 m, respectively, it is preferable that L is approximately 85 mm, 135 mm, and 250 mm. The element was provided with two deformed passages 12 and 13, but as shown in FIG. 8, an element was provided with four deformed passages 22, 23, 24 and 25. The kneading device 10 can also be configured by connecting 21. The concept of this element 21 is the same as that of the above-mentioned elements 11a and 11b, and the opening on the end side is entirely as a whole. It is square and has a flange F for connection around it, and three partitions 端 26, 27, 28 so that the entrance end forms four openings that are long in the X direction. Deformation The entrances 22 a, 23 a, 24 a and 25 a of the roads 22 to 25 are described.

On the other hand, the outlet side end of the element 21 has three openings 29 different from the respective inlets of the inlet side end so as to form a long opening in the Y direction, which is different in direction by 90 degrees. , 30 and 31 and the outlets 2 2 b, 2 3 b, 2 4 1], 25 b of each deformed passage Have been. Then, as shown in FIG. 8, the inlet 22a of the deformed passage 22 communicates with the second outlet 22b from J :, and the inlet 23a of the deformed passage 23 is located at the top. Out: communicates with the section 23b, the inlet 24a of the deformed passage 24 communicates with the lowermost outlet 2'1b, and the inlet 25a of the deformed passage 25 It communicates with the third outlet 25b. The change in the cross-sectional shape in the longitudinal direction of each of the deformed passages 22, 23, 24, and 25 is basically the same as the case of the elements 11a and lib shown in the previous embodiment. is there. However, the outline of the entire element 21 is different because it has four deformed passages.

FIG. 9 shows a process diagram of a kneading method using a kneading apparatus configured by connecting two elements 21 (in this example, connecting elements 21 having the same shape). The material to be kneaded in the rectangular inlet portion 22a to 25a, which is long in the X direction, at the inlet end of the first stage element 21 1 when exiting the outlet portion 22b to 25b The rows are divided into B, A, D, and C, and at the exit side end of the second-stage element 21, the rows are joined in a state of 16 layers long in the X direction. Here, the imaginary line X3 indicates the next third division line.

ADVANTAGE OF THE INVENTION According to the kneading apparatus of this invention, the kneading | mixing of the fluid to-be-kneaded by passing through the deformation | transformation path whose cross-sectional shape changes continuously by free fall by an own weight from an inlet part to an outlet part is carried out. Since the cross-sectional shape of the material changes continuously with respect to the cross-sectional shape of the deformed passage, and the material to be kneaded is merged and divided by the merging and dividing means while passing through each deformed passage, the compressive action is applied to the material to be kneaded And a deformation action based on it. As a result, the kneading can be efficiently performed by a mechanical device having a relatively simple structure that has no direct moving parts and thus does not cause wear or damage prevention. At this time, the deformed passage is configured so that there is no straight through passage, so that the kneading efficiency as designed can be obtained.

Further, according to the kneading apparatus of the present invention, each of the elements is constituted by at least two types, each of which has a different communication mode between each part of each deformed passage and the above-mentioned outlet part. Since different elements are alternately connected vertically, the kneading effect of the material to be kneaded when passing through the T-stage element can be further improved. Moreover, two kinds of Ereme down bets have effective recruitment requires only a simple configuration to connect ₃ Industrial applicability

INDUSTRIAL APPLICABILITY The present invention can be used for a mixer for producing concrete mortar or the like or for kneading or mixing two or more kinds of fluid materials. In addition, the present invention is suitable for mass production because the entire device has a simple configuration.
