Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of a liquid manure production apparatus according to an embodiment of the present invention.

Referring to FIG. 1, a liquid manure production apparatus 100 according to an embodiment of the present invention includes a stirring tank 110, an in-line mixer 120, a first control unit 130 and a second control unit 140. do. In addition, the liquid manure manufacturing apparatus 100 according to an embodiment of the present invention further includes a fermentation agent supply unit 150 and an air supply unit 160.

The stirring tank 110 uniformly agitates food waste, agricultural by-products, manure, etc., which are objects to be stirred, which are introduced from the outside, to create a stirred product and then discharge it. In addition, the stirring tank 110 supplies a fermentation agent to be described later to the stirred material to perform fermentation to produce liquid manure.

The stirring tank 110 has a cylindrical shape having a predetermined diameter and length, and provides a space in which stirring and fermentation are performed. In addition, the lower portion of the stirring tank 110 is made in the shape of a hopper whose diameter decreases toward the end.

A supply pipe 112 for inputting the object to be stirred is connected to an upper side of the stirring tank 110, and a discharge pipe 114 for discharging the stirred substance is connected to the lower center.

Here, the agitation object supply pump (P) is disposed on the supply pipe 112, a predetermined pressure is applied to the stirring object, and the supply can be made easily.

In addition, the first and second intermittent portions 130 and 140 to be described later are connected to the end of the discharge pipe 114.

After receiving the agitated material discharged from the stirring tank 110, the in-line mixer 120 supplies air and a fermenting agent to the agitated material so that they are uniformly mixed with each other. A configuration for supplying air and a fermenting agent will be described later.

FIG. 2 is a diagram showing the configuration of the in-line mixer shown in FIG. 1, and FIG. 3 is a diagram illustrating a flow of a mixture target material of a stirrer in the in-line mixer of FIG. 2.

2 and 3, the in-line mixer 120 according to the present embodiment includes a first case 1210 and a second case 1220, a spiral injection unit 1213, and a turbulence generator 1211. do.

The first case 1210 and the second case 1220 have a pipe shape, and the second case 1220 is disposed at the other end of the first case 1210.

The spiral injection part 1213 has a pipe shape and includes two inclined guides 1213-2 therein. The inclination guide 1213-2 is formed protruding from the inner circumferential surface, is formed to be inclined to one side and the other side, and is rotationally symmetrical about a central axis.

The turbulence generating portion 1211 has a turbulent flow protrusion 1211-1 that has a ring shape and protrudes from an inner circumferential surface. At least two or more of the turbulence generating units 1211 are inserted into the first case 1210 and overlapped on the other side of the spiral jet unit 1213. At this time, the positions of the turbulence protrusions 1211-1 of the turbulence generator 1211 adjacent in the overlapping direction do not overlap.

Referring to FIG. 3, it is possible to confirm the mixing process of the agitated material.

The stirred material introduced from one side of the first case 1210 is divided into two flow paths a1 and a2, and passes through the inclined guide 1213-2. The agitated material passing through the inclined guide 1213-2 proceeds by forming a spiral vortex.

The agitated material injected into the turbulence generator 1211 proceeds while forming a turbulent flow by the turbulence protrusion 1211-1. As described above, a plurality of turbulence generators 1211 are overlapped and disposed inside the first case 1210. At this time, the positions of the turbulence protrusions 1211-1 of the turbulence generating unit 1211 that overlap are not overlapped and are arranged in a zigzag along the axial direction. Accordingly, the agitated material collides with the plurality of turbulence protrusions 1211-1 while passing through the plurality of turbulence generating portions 1211, thereby improving mixing efficiency.

In addition, mixing efficiency can be further improved by increasing the length of the first case 1210 and increasing the number of overlaps of the turbulence generator 1211.

In the in-line mixer, by separating the spiral injection unit 1213 for spirally advancing the agitated material, the turbulence generating unit 1211 for generating turbulence in the agitated material, and the first case 1210 accommodating the same, the assembling property is improved and mixed. It is easy to control the efficiency. In addition, by overlapping the turbulence generators 1211 of the same shape to generate turbulence, mixing efficiency can be controlled at low manufacturing cost, and a turbulence generating structure having high mixing efficiency can be easily manufactured.

In conclusion, the fully discharged agitator to which the in-line mixer according to the present invention is applied, through the process of re-injecting the agitated material after passing through the in-line mixer 120 after being discharged from the stirring tank 110, Can be mixed.

That is, in a general rotary vane type stirrer, a part of the agitated material is stagnated according to the structure of the stirrer, so that the overall mixing efficiency is deteriorated, and there may be a problem that the mixing uniformity is lowered. By circulating through the bath and the in-line mixer, mixing efficiency can be improved and mixing uniformity can be improved.

In addition, after all of the stirred material is injected and accommodated in the stirring tank, it may be circulated to the in-line mixer through the first intermittent unit 130. In this way, not only can the mixing efficiency uniformity of the whole mixture be improved, but also the ratio of the constituent materials constituting the mixed mixture can be maintained uniformly.

In addition, by installing the in-line mixer 120 with improved assembly properties outside the stirring tank 110 to mix air and the fermenting agent, there is an advantage in that there is no need to install a separate aeration device inside the stirring tank.

In addition, by controlling the pumping pressure of the pump, by controlling the injection pressure of the agitated material injected from the in-line mixer 120 to the stirring tank 110, the strength and weakness of the mixing action inside the stirring tank 110 and the in-line mixer 120 Can be controlled.

2 and 3, in the in-line mixer of the present embodiment, the spiral injection unit 1213 may further include a fluid splitting unit. The fluid dividing portion is disposed concentrically inside the helical injection portion 1213 in a cylindrical shape.

By the fluid division part 1213-1, the fluid passage area of the spiral injection part 1213 is reduced. As the fluid passage area decreases, the flow velocity increases when the agitated material passes through the spiral injection portion 1213. Therefore, the spiral injection unit 1213 including the fluid dividing unit injects the stirred material at high speed in the spiral travel direction. When the flow velocity of the agitated material rises, the turbulence generated by the turbulent protrusion 1211-1 becomes more active.

In addition, in the in-line mixer according to the present invention, the turbulent protrusion 1211-1 may further include at least one protruding bulb 1211-11 protruding laterally in the protruding direction. The protruding bulb 1211-11 has the effect of further improving the mixing efficiency by further activating the formation of turbulence due to the turbulent protrusion 1211-1.

4 and 5 are views for explaining the arrangement of turbulence protrusions according to the overlapping of the turbulence generation unit in the in-line mixer according to the present invention.

Referring to FIGS. 4 and 5, by rotating and overlapping the turbulence generating units of the same shape, it can be seen that the turbulent protrusions of the adjacent turbulence generating units do not overlap in the overlapping direction.

Referring to FIG. 4, arrangement forms of the first turbulent protrusions 1211-31 and the second turbulent protrusions 1211-41 are different from each other. However, the first turbulence generator 1211-3 and the second turbulence generator 1211-4 have the same shape, and when the first turbulence generator 1211-3 is rotated at a specific angle, the second turbulence protrusion 121-1 41) can be formed.

Referring to FIG. 5, when the first turbulence generator 1211-3 and the second turbulence generator 1211-4 are overlapped so that the diameter line L1 coincides, the first turbulence protrusions 1211-31 It can be seen that the second turbulent protrusions 1211-41 are disposed. At this time, the first turbulent protrusion 1211-1 and the second turbulent protrusion 1211-1 are arranged in zigzag along the central axis direction, and the arrangement of the turbulent protrusion 1211-1 shown in FIGS. 2 to 3 can be implemented. have.

6 and 7 are views for explaining the arrangement of turbulent protrusions that are not line-symmetric with respect to the diameter line in the in-line mixer according to the present invention.

2, 6, and 7, in the in-line mixer according to the present embodiment, the turbulence generator 1211 further includes a fastening hole 1211-2.

The fastening hole 1211-2 is formed through one surface and the other surface along the circumferential direction of the third and fourth turbulence generating units 1211-5 and 1211-6, and the fixing pin 1212 is inserted. At this time, the fastening hole 1211-2 is arranged in a line symmetrical with respect to the specific diameter line L1. On the other hand, the turbulent protrusions 1211-51 and 1211-61 are not arranged in a line symmetry with respect to the diameter line L1.

The third turbulence generator 1211-5 and the fourth turbulence generator 1211-6 in FIG. 6 have the same shape. When the third turbulence generator 1211-5 is turned over, the shape of the fourth turbulence generator 1211-6 can be obtained. That is, if the two third turbulence generators 1211-5 are overlapped, but one of them is stacked upside down, the overlapped turbulence protrusions arrangement of FIG. 7 can be obtained.

In conclusion, the third and fourth turbulence generation units 12115 and 1211-6 according to the present embodiment use the turbulence generation unit 1211-5 of the same shape, and the turbulence protrusions 1211-51 along the traveling direction of the agitated material. ) Can be placed in zigzag. In addition, by inserting the fixing pin 1212 into the fastening hole 1211-2, it is possible to fix the state of the stacked structure of the plurality of turbulence generating units 12115 and 1211-6.

In addition, in the in-line mixer according to the present embodiment, the turbulence protrusions 1211-51 may be preferably equiangularly disposed with respect to the central axis of the turbulence generators 1211-5 and 1211-6. Since the overlapping turbulence protrusions 1211-51 and 1211-61 are arranged at an equal angle, uniform mixing efficiency characteristics can be obtained along the inner circumferential surfaces of the turbulence generators 1211-5 and 1211-6.

In addition, in the in-line mixer according to the present embodiment, the turbulence generating unit 1211 may further include a protrusion coupling hole that is recessed in the inner circumferential surface to insert the protrusion to be screwed. By separating the turbulence protrusion 1211-1 from the turbulence generating unit 1211, there is an advantage in that assembly and production of the turbulence generating unit 1211 are facilitated.

In addition, in the in-line mixer according to the present embodiment, the material of the turbulence generating units 1211-5 and 1211-6 is preferably made of SUS. In general, in order to form the shape of the turbulence generating portions 1211-5 and 1211-6, which are complex protruding structures, using SUS material, a casting method must be used. However, the casting method requires expensive manufacturing equipment and subsidiary materials such as mold design and manufacturing.

In the in-line mixer according to the present invention, the turbulence generators 1211-5 and 1211-6 of the same shape are overlapped and disposed. Therefore, there is an advantage in that it is easy to manufacture using SUS materials.

The sixth turbulence generation unit 1211-8 and the seventh turbulence generation unit 1211-9 are obtained by rotating the fifth turbulence generation unit 1211-7 at a specific angle, and have the same shape.

That is, when the fifth turbulence generator 1211-7 is rotated and superimposed at a specific angle and this combination is repeated, the turbulence protrusions 1211-71, 1211-81, and 1211-91 are arranged in a spiral. The overlapped turbulent protrusions 1211-71, 1211-81, and 1211-91 are more dense than the arrangement spacing of the turbulent protrusions 1211-51 and 1211-61 of FIG. 7. On the other hand, the arrangement of the turbulence protrusions (1211-71, 1211-81, 1211-91) of the turbulence generation unit combination (1211-10) of FIG. Can be further improved.

While the agitated material circulates between the agitation tank 110 and the in-line mixer 120, the first valve V1 is opened, but the second valve V2 is kept closed so that the agitated material is not fermented. To be prevented from being discharged to the outside.

Here, when the agitated material circulates through the stirring tank 110 and the in-line mixer 120, the amount of the agitated material through the supply pipe 112 is measured by the flow sensor 154, and the fermentant corresponding to the measured amount is supplied. .

Here, the supplied fermenting agent is an EM (Effective Microorganisms; useful microorganism) fermenting agent, and is widely used in this field, so a detailed description thereof will be omitted. The fermenting agent is supplied to an in-line mixer and mixed with the agitated material, and the agitated material is fermented.

In order to facilitate fermentation, it is necessary to supply air to the agitated material.

The dissolved oxygen demand measurement sensor 164 measures the dissolved oxygen demand, and if necessary, air is supplied to the in-line mixer 120 through an air supply pump P4 to mix the agitated material and air.

When the agitated water in the stirring tank 110 is fermented and becomes liquid fertilizer, the first valve V1 of the first control unit 130 is closed, and the second valve V2 of the second control unit 140 is opened. It is possible to supply liquid manure to the place where it is used.

In the present invention as described above, when a stirring object including food waste, agricultural by-products, and manure is input from the outside, the mixture is stirred in a stirring tank and then mixed with the fermenter in an external in-line mixer, and then put into the stirring tank again. So that the fermentation proceeds. In addition, according to the present invention, the lower part of the stirring tank is formed in a shape of a hopper whose diameter decreases toward the end of the stirring tank, so that unstirred objects to be stirred can be prevented from accumulating in the lower inside of the stirring tank. In addition, in the present invention, since the fermentation agent is supplied to and mixed with the stirred material in an in-line mixer disposed outside the stirring tank, the fermentation of the stirred material is made more effectively.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those of ordinary skill in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
