Description

Food garbage disposer

The present invention relates to a food waste treatment apparatus, and when the food waste is put in, the food waste is processed by crushing, compressing, and dehydrating, and it relates to a food waste processing apparatus that solves the phenomenon of clogging of waste in the drain.

As environmental problems arise, various food waste treatment devices have been developed. In particular, many treatment devices for grinding, compressing and dehydrating food waste have been developed.

Korean Patent No. 207851 decelerates the driving force of the up / down driving motor, applies compression to food waste, uniformly disperses the crushed food waste accumulated in the compression container by the impeller and compresses the food waste, thereby crushing the particles. It is a device that compresses the food waste uniformly and drains sewage into the sewage pipe naturally, and draws out the remaining residue.

Utility Model No. 139822 is a device having a structure in which food waste is compressed and dewatered using a crushing screw and a crushing screw with a cutting knife, and the dehydrated liquid is dried over a mesh board to be powdered compost and placed in a collection box.

In such a device, a plurality of drainage holes are formed in the cylinder wall in order to discharge the sewage falling out of the rotating cylinder of the screw so that the sewage is discharged. Sewage, which is compressed and dehydrated as food waste is pushed by the rotation of the screw, is discharged to the outside through drain holes in the cylinder.

The development of the food waste treatment device facilitates the treatment of food waste that has been treated, and has helped a lot in protecting the environment. However, it often happens that food waste gets stuck in the drain. It is preferable that the waste water drainage is reduced so that only the sewage drains out. However, since the drainage hole is small, the food waste often gets stuck here.

Developed to prevent this, Utility Model Registration No. 158934 includes a structure that periodically cleans the drain network by installing a brushed subtractor in the drain network of the drain hole. However, it is very inconvenient to periodically clean the drainage network artificially, which undermines the basic purpose of automatically disposing of food waste.

Thus, the inventors of the present invention while studying a food waste treatment device that does not trap waste in the drain hole without artificial cleaning work, if the cylinder is formed by stacking a plurality of ring-shaped thin plates at minute intervals without drilling the drain hole in the cylinder, the entire cylinder circumference The gap between the ring-shaped thin plates can be made very small due to the drainage of sewage, and each ring-shaped thin plate also slides and rotates as the screw rotates in the cylinder, so even if food waste gets caught between the ring-shaped thin plates, By devising a structure that can not be trapped by the debris.

Accordingly, an object of the present invention is to provide a food waste treatment apparatus adopting a structure in which food waste is processed by crushing, compressing, and dehydrating food waste, and the waste of food waste cannot be caught.

It relates to a food waste treatment device. The processing means includes a cylinder formed by stacking a plurality of ring-shaped thin plates, and a screw for compressing and dehydrating food waste injected by rotating in the cylinder.

The spacer is attached to one surface of the ring-shaped thin plate, and the gap with the adjacent thin plate is kept constant when the ring-shaped thin plates are laminated. The shape of the ring-shaped thin plate can be produced in various shapes. However, the inner diameter of the ring must be circular because the screw rotates in contact with the inner diameter of the ring.

In addition, as the wing of the screw contacts and rotates the inner diameter of the ring-shaped thin plate forming the cylindrical shape, the ring-shaped thin plates may rotate while independently sliding while maintaining the cylindrical shape, thereby always moving and removing the residue caught in the gap. can do.

The present invention, in the above structure, in order to drain the water contained in the food waste, the first tube, the second tube is inserted into the first tube and smaller than the inner diameter of the first tube, and inserted into the second tube The third tube of the outer diameter smaller than the inner diameter of the second tube, ..., the n-th tube of the outer diameter smaller than the inner diameter of the (n-1) tube is inserted into the (n-1), n-th tube The drainage port is inserted into the inner diameter of the n-th tube smaller than the inner diameter of the n-th tube, and the drain hole consisting of a fixing pin for allowing each of these tubes and the mandrel to flow independently, close to the bottom of the screw, the blade of the screw rotates the first to n Independently flowing the pipe and the mandrel is characterized in that the sewage is drained between the pipes while draining.

Example Configuration

An embodiment of the present invention will be described with reference to the drawings. Referring to Figure 1, the food waste treatment apparatus according to the present invention (hereinafter, 'the present invention') is, as a whole, food waste input unit 10, a crusher 20 for finely crushing the input food waste, crushed food waste It is composed of a processing unit 30 for compressing the dehydration by the motor, a drain 60 for discharging the sewage discharged from the processing unit 30 to the sewer and a food waste discharge unit 50 for discharging the dehydrated food waste.

Food waste inlet 10 is a place to put the food waste to be treated, is connected to the drain 11 of the sink. Therefore, food waste can be disposed of in the sink without handling food waste separately, which is convenient.

The input food waste is pulverized finely by the grinder 20. The grinder 20 consists of a rotating blade, which is configured to rotate by the motor 21. Although not shown in FIG. 1, it is obvious to those skilled in the art to rotate the rotary blade by a motor.

The processor 30 is a part constituting the features of the present invention, and will be described in detail with reference to FIGS. 1 to 4.

The processing unit 30 is composed of a cylinder 31 and a screw 33. As shown in FIGS. 2 and 3, the cylinder 31 is formed by stacking a plurality of ring-shaped thin plates 37 in a space formed by four support rods 35. On one surface of each ring-shaped thin plate 37, spacers 39 are attached in four places. Therefore, gaps exist at regular intervals between the stacked ring thin plates 37.

2, since each ring-shaped thin plate 37 has no fixed point anywhere, it can be seen that each can rotate freely independently. Of course, although not shown in the drawings, the front and rear of the cylinder should be attached to the support plate 35 so that the ring-shaped thin plate 37 is not separated.

2 and 4, the shape of the ring-shaped thin plate 37 shows a circular shape, but if only the inner diameter of the thin plate 37 is circular so that the screw 33 can rotate to the inner diameter of the thin plate 37 as described above, The outer shape of the thin plate 37 may be any shape. For example, it may be a polygon such as a square or a pentagon. This is a technical matter for those skilled in the art to determine by design.

Screw 33 can be seen in Figure 1, the rotary blades rotate to produce a force to push in the front (front) direction. Screw 33 is a mechanical element also used in the conventional food waste processing apparatus. The screw 33 rotates by the motor 21. It is connected to the rotating shaft of the motor 21 through the chain 23 receives the rotational force of the motor. As one motor 21, the structure for rotating the grinder 20 and the screw 33 together will be obvious to those skilled in the art. Referring back to FIG. 1, the present invention is based on the idea that the screw 33 is compressed while pushing the food waste while the screw 33 rotates inside the cylinder 31 formed by stacking ring-shaped thin plates. 4 is a sectional view taken along the line A-A in FIG. 3, showing that the screw 33 is located in the inner space of the ring-shaped thin plate 37. As shown in FIG.

1, the drainage part 60 is demonstrated. Drainage 60 is a place for discharging sewage dewatered from the food waste, the sewage from the primary drain (61) to discharge the water contained in the food waste first, the cylinder before entering the food waste into the cylinder 31, the cylinder Sewage discharged through the space between the stacked ring-shaped thin plates 37 of 31 is collected and discharged to the sewer through the drain pipe 63. 1, it can be seen that two primary drain holes 61 are provided.

The structure of the primary drain 61 is demonstrated. FIG. 5 is a plan view of the primary drain 61, FIG. 6 is an internal perspective view, and FIG. 7 is a sectional view taken along line B-B showing the interaction between the screw 33 and the primary drain 61. FIG. The primary drain 61 is inserted into the first tube 61a and the first tube 61a, but is inserted into the second tube 61b and the second tube 61b having an outer diameter smaller than that of the first tube 61a. It is inserted into the third tube (61c), ..., the seventh tube (61g) of the outer diameter smaller than the inner diameter of the second tube (61b) consists of a core rod 62 of the outer diameter smaller than the inner diameter of the seventh tube (61g). The first to seventh pipes 61a to 61g and the mandrel 62 are rotatably fixed by the fixing pin 64, and the first to seventh pipes 61a to 61g and the mandrel 62 are rotated. Can flow independently.

There is a clearance of about 0.5 mm to 1 mm between the first to seventh pipes 61a to 61g and the core rod 62. Thus, if each tube flows separately, the gap between each tube will change from time to time.

The upper surface of the primary drain port 61 configured as described above is curved to match the outer diameter of the rotary blade of the screw so that the screw can rotate in contact with the screw 33 (see FIGS. 6 and 7).

In addition, the part which is not demonstrated above is further demonstrated. The upper part of the cylinder 31 is connected to the water overflow prevention drain hole 12 installed on the sink side of the sink is provided with an inlet 13 for washing the cylinder 31 using the water overflowing the sink. The sewage drained into the gap between the ring-shaped thin plates 37 of the cylinder 31 by entering the inlet 13, the sewage generated by dehydration from the food waste, and the sewage discharged from the primary drain 61 are gathered together to form a drain pipe 63. Discharged through the sewers.

Action of Example

Food waste dumped in the sink enters the input unit 10. The food waste entering the input unit 10 is crushed finely by the grinder 20. Since the rotary blades of the grinder 20 are very dangerous, the distance between the sink drain 11 and the grinder 20 is such that the human body, in particular, is out of reach, or the inlet 10 is perpendicular to the drain 11 of the sink. It is preferred to be placed at an angle rather than at the bottom.

Finely broken food waste enters the processing unit 30. Food waste entering the treatment unit 30 is pushed forward by the rotation of the screw (33). At this time, the sewage contained in the introduced food waste is discharged by the primary drain 61 and collected in the drain 60. As described above, since the primary drain port 61 is configured to allow the plurality of pipes to flow independently by the fixing pin 64, the upper surface in contact with the screw 33 is the rotary blade of the screw 33. It is moved by the rotor blades in an oblique spiral motion, so the movement of each tube is different.

Therefore, in the primary drain 61, there is no room for crushed food waste. This is because each pipe constituting the primary drain 61 flows independently and can be removed even if any debris is caught.

Food waste continues to be pushed forward by the rotation of the screw 33 and enters the cylinder 31. Since the food waste continues to push, the food waste is compressed and dehydrated by the rotary blades of the screw 33. The dewatered sewage is collected into the drainage part 60 through the gap between the ring-shaped thin plates 37 forming the cylinder 31.

In the present invention, since the hole for drainage is not formed in the lower part of the cylinder as in the prior art, food waste does not become clogged because there is a gap over all the circumferences of the cylinder 31.

In addition, since the rotary blades move in a spiral motion by the rotation of the screw 33, since each of the ring-shaped thin plates 39 in contact with the rotary blades can be rotated independently, the waste of food waste between the thin plates 39. Do not get caught. Even if it is stuck, it can be removed soon by the rotation of the ring-shaped thin plate 39, the residue can not be caught in the cylinder (31).

The dehydrated food waste is finally discharged to the food waste discharge unit 50. Sewage collected in the drainage portion 60 exits the sewer through the drainage pipe 63.

As described above, the feature of the present invention is not to form a separate drainage hole in the cylinder 31, the cylinder itself is composed of a laminated ring-shaped thin plate 37, between each thin plate 37 With a clearance, each thin plate 37 is rotated independently by the rotation of the screw 33, so that the residue is not caught in the clearance.

In addition, by configuring the structure of the primary drain (61) for draining the sewage contained in the food waste, as shown in Figure 5, by allowing the respective pipes to be flowed independently by the rotation of the screw 33, so as not to get garbage have.

In the above, embodiments of the present invention have been described through embodiments, but the technical idea of the present invention is not limited thereto. In other words, it is possible for a person skilled in the art to variously modify the technical idea of the present invention within the technical scope of the claims. Therefore, all modifications included in the claims will be included in the technical scope of the present invention. In addition, it is apparent that the present invention can be used not only for the treatment of food waste, but also for the treatment of various industrial wastes.

As described above, according to the present invention, a plurality of ring-shaped thin plates are laminated at intervals of a minute interval in the cylinder so as to prevent debris from being caught in the drainage holes without artificial cleaning work, so that sewage is drained over the entire cylinder circumference. Since the gap can be made very small and each thin plate rotates while the screw rotates in the cylinder, even if food waste is stuck between the thin plates, the waste cannot be caught because of the rotation of the thin plate.

In addition, by employing a primary drain that overlaps a plurality of pipes, each pipe flows independently by the rotation of the screw, so that the wastewater contained in the food waste can be discharged primarily.
