Referring to FIG. 2, the kitchen waste pretreatment apparatus 100 according to the present invention may be installed in the sink 6 installed in a home kitchen. Inside the sink 6, a kitchen crusher 11 is installed to finely crush kitchen trash such as food waste generated after washing dishes in the sink. The kitchen waste grinder 11 may be equipped with a control unit 12. The kitchen crushed in the kitchen crusher 11 is discharged together with the water to the indoor pipe through the pipe (7) connected to the crusher (11).

Kitchen waste pretreatment apparatus 100 according to the present invention is a portion that is connected to the kitchen crusher 11 is a kitchen crushed finely by the crusher 11 and the water flows in and out. Kitchen waste pretreatment device 100 is a large portion of the crushed kitchen filth included in the water is to be deposited or precipitated inside the pretreatment device 100 to reduce the discharge to the indoor piping and relatively small crushed kitchen filth Only by selectively discharged into the indoor pipe, kitchen waste with a large specific gravity can be deposited inside the indoor pipe to prevent or prevent the indoor pipe from being blocked. Hereinafter, the kitchen waste pretreatment apparatus 100 will be described in more detail with reference to the accompanying drawings.

3 and 4, the kitchen waste pretreatment apparatus 100 according to an embodiment of the present invention has an inflow port (2) into which the kitchen water crushed by the kitchen waste grinder 11 is introduced. 111 and a sedimentation case (110,160) having an outlet port 112 to be discharged may include a baffle (190) formed in the sedimentation case (110,160) to precipitate the kitchen filth contained in the flowing water.

By using the kitchen waste pretreatment device 100 as described above, it is possible to block the large amount of kitchen waste from being discharged into the indoor pipe or the sewage treatment pipe, thereby reducing the blockage of the indoor pipe or the sewage treatment pipe.

Here, the precipitation case (110,160) may be formed separately from the outer case 110 and the inner case 160, or may be formed of one precipitation case in which the outer case and the inner case is integrated. 3 and 4 exemplarily show a sedimentation case formed separately from the outer and inner cases 110 and 160.

The inlet port 111 through which the pulverized kitchen filth enters the precipitation cases 110 and 160 together with the water is provided with an inlet pipe connection part P1 connected to the pipe 7, and the outlet port 112 is connected to the indoor pipe. The outflow pipe connection portion P2 may be provided.

The baffle 190 may be formed in the precipitation cases 110 and 160, and when the precipitation cases 110 and 160 are separately formed into the outer and inner cases, the baffle 190 may be formed in the inner case 160.

The baffle 190 is formed in close proximity to the inlet port 111, thereby obstructing the flow of flowing water containing the kitchen effluent flowing through the inlet port 111, so that the kitchen soil having a wet density of the kitchen filth exceeding a predetermined standard is precipitated. It is possible to reduce the outflow from the (110,160) to the outside. Since the flow of water including the crushed kitchen waste is blocked by the baffle 190, turbulence or vortex of water occurs between the baffle 190 and the inlet port 111, which causes the baffle 190 and the inlet port ( 111) may lengthen the time the water stays between.

As such, by preventing the flow of the water flowing through the inlet port 111 to prevent the water is quickly discharged through the outlet port 112, and by staying to some extent between the inlet port 111 and the baffle 190, A large specific gravity of the kitchen filth may be induced to be caught on the baffle 190.

At this time, it is preferable that the distance between the inflow port 111 and the baffle 190 is close, and the baffle 190 is formed at a position facing the inflow port 111. This is because the baffle 190 is located close to the inflow port 111 and faces the inflow port 111 so that the flow of the incoming water can be disturbed as much as possible and the flow of water can be changed. This is because it can be secured.

Here, the baffle 190 may be spaced apart from at least one inner wall of the inner walls of the precipitation case (110,160). In the case where the precipitation case is formed into the outer and inner cases 110 and 160, the baffle 190 is preferably formed to be spaced apart from at least one inner wall of the inner wall or the side wall of the inner case 160. As a result, water containing a small specific gravity may flow out of the space or gap between the baffle 190 and the inner wall.

A hole 191 may be formed at an upper end of the baffle 190, and the inner case 160 may be separated from the outer case 110 using the hole 191. Since the baffle 190 is fixed to the inner case 160, the outer case 110 and the inner case 160 may be separated by putting a finger on the hole 191 of the baffle 190 and pulling the baffle 190. . This is only the case when the precipitation case is formed of an outer and an inner case.

When the outer case 110 and the inner case 160 are separately formed, it is easy to remove the kitchen waste having a large specific gravity deposited or deposited on the inner case 160. The outer case 110 may be used again by removing the kitchen dirt deposited by separating only the inner case 160 while being connected to the pipe, and then mounting the inner case 160 to the outer case 110.

In the case of using a single precipitation case in which the outer case 110 and the inner case 160 are integrally formed, in order to discard the kitchen sediment deposited in the sedimentation case, disconnect the sedimentation case after disconnecting the pipe and the sedimentation case. It should be possible. To this end, when a single precipitation case is used, a valve (not shown) for temporarily blocking the flow of water between the precipitation case and the pipe and a separation means (not shown) for releasing the connection between the pipe and the precipitation case are provided. Should be.

As mentioned above, when the precipitation case is formed into the outer case 110 and the inner case 160, the inlet port 111 and the outlet port 112 are formed in the outer case 110 and the baffle 190 ) May be formed in the inner case 160.

In the case where the inner case 160 is removed to remove the deposited kitchen soil, the inner case 160 includes not only the kitchen soil but also water, so that the water can be drained at the moment when the inner case 160 is separated. A drain hole 162 may be formed on the sidewall or bottom of the case 160. The size of the drain hole 162 is suitable if the kitchen sewage accumulated in the inner case 160 is not enough to escape through the drain hole 162. The drain hole 162 need not be formed throughout the side wall or the bottom, and may be formed only in a part of the side wall or the bottom.

As shown in FIG. 4, a sealing member 170 may be formed on the outer surface of the inner case 160 to closely contact the outer case 110 and the inner case 160. The sealing member 170 may allow the inner case 160 to be stably mounted to the outer case 110, and may be formed only on any portion of the outer surface of the inner case 160.

The inlet port 111 formed in the precipitation case or the outer case 110 may be formed at a position not higher than the outlet port 112. When the inlet port 111 is formed high, the water passing through the inlet port 111 falls to the bottom of the inner case 160 and the kitchen filth is not blocked by the baffle 190 by the impact thereof. It is preferable that the formation position of the inflow port 111 is low because it can pass. In addition, when the outflow port 112 is low, since the kitchen waste having a large specific gravity blocked by the baffle 190 may be discharged together with the water, the formation position of the outflow port 112 is preferably high.

The upper end of the inner case 160 may be formed lower than the lowermost end of the inflow port 111. This is because the inlet port 111 is not blocked by the inner case 160 when the upper end of the inner case 160 is lower than the lower end of the inlet port 111.

Hereinafter, various embodiments of the kitchen waste pretreatment apparatus according to the present invention will be described with reference to the accompanying drawings. 5 to 9 to be described below, only the contents for explaining the shape of the precipitation case, the inlet port, the outlet port and the shape / position of the baffle are schematically illustrated.

5 is a view schematically showing a first embodiment of the kitchen waste pretreatment apparatus according to the present invention. The sedimentation case 210 of the kitchen waste pretreatment apparatus 200 shown in FIG. 5 has a square bottom and has an elongated shape up and down, and has a capacity of 5 liters. That is, the precipitation case 210 has a height (c1) is formed longer than the length (a1) and the length (b1) of the bottom surface. The width a1 and length b1 of the bottom surface are 12.5 cm, respectively, and the height c1 is 24.5 cm. The diameters i1 and j1 of the inlet port 211 and the outlet port 212 are 5 cm, and the heights e1 and d1 of the centers of the inlet port 211 and the outlet port 212 are 18.5 cm, respectively. That is, the inlet port 211 is formed in the outlet port 212 at the same height.

The sidewall on which the inlet port 211 is formed and the sidewall on which the outlet port 212 is formed are adjacent to each other, and the baffle 290 may be formed on the sidewall facing the inlet port 211, but may be inclined downward. The inclination angle θ1 of the baffle 290 is 60 degrees, the width g1 of the baffle 290 is 11 cm, and the length f1 is 12.5 cm.

The baffle 290 is formed on a side wall facing the side wall on which the inlet port 211 is formed, and the side wall on which the inlet port 211 is formed is spaced apart from the baffle 290. The distance h1 is 3 cm apart. Referring to FIG. 5, the baffle 290 may be formed below the outlet port 212.

The kitchen waste pretreatment device 200 formed as described above has a specific gravity of the water introduced through the inflow port 211 hits the inclined baffle 290 and then falls to the bottom through the interval h1 between the side wall and the baffle 290. This large kitchen waste can be deposited.

Precipitating experiment of kitchen filth was performed using the kitchen filth pretreatment apparatus 200 shown in FIG. 5, and the results are shown in Table 1 below.

Kitchen Sewage Pretreatment Outflow Rate (%) Transverse pipe deposition Transverse deposition Uncooked rice 29 △ △ Egg shells 37 △ △ Chicken bone 74 △ △ Pickled Chinese Cabbage 100 × × Seaweed 100 × ×

Here, ○ means most of the deposition, Δ means a small amount of deposition, × means no deposition, which is the same below.

Seaweed and pickled cabbage, which is a relatively small fraction of food waste, were discharged into transverse pipes and transverse pipes without any deposits inside the pretreatment system, and quickly discharged out of the pipes according to the flow of water. In contrast, uncooked and egg shell mills have been found to deposit significant amounts in processing. The most common deposits were raw rice (71%), followed by egg shells (63%) and chicken bone (26%). As can be seen from this result, it can be seen that a large portion of the kitchen filth, such as raw rice, egg shells, chicken bones are crushed and then partially deposited or precipitated in the kitchen filth pretreatment device 200 to prevent the entire amount from being discharged.

6 is a view schematically showing a second embodiment of the kitchen waste pretreatment apparatus according to the present invention. In the kitchen waste pretreatment device 300 illustrated in FIG. 6, the bottom of the precipitation case 310 is approximately rectangular and the height is shorter than the long side of the bottom, and the total capacity is 9 liters.

The width a2 of the bottom (bottom) of the precipitation case 310 is 26 cm, the length b2 is 20 cm, and the height c2 is 17.5 cm. The inlet port 311 is formed on the front sidewall of the precipitation case 310 and the outlet port 312 is formed on the rear sidewall of the precipitation case 310. At this time, the inlet port 311 is at a lower position than the outlet port 312. That is, the height h2 of the inlet port 311 is 4.5 cm and the height k2 of the outlet port 312 is 11.5 cm. The diameters i2 and j2 of the inlet port 311 and the outlet port 312 are all the same at 5 cm.

In the kitchen waste pretreatment apparatus 300 illustrated in FIG. 6, the baffle 390 may be formed in a direction orthogonal to the sidewall on which the inlet port 311 is formed and the sidewall on which the outlet port 312 is formed. In other words, it can be said that the baffle 390 is formed in a direction substantially parallel to or coincident with the flow direction of the water passing through the inlet port 311 and the outlet port 312.

The baffle 390 is attached to the sidewall on which the outlet port 312 is formed, but is spaced apart from the sidewall on which the inlet port 311 is formed. The spaced distance between the side wall on which the inlet port 311 is formed and the baffle 390 is about 3 cm. This is because the width e2 of the baffle 390 is 17 cm.

In addition, the height d2 of the baffle 390 may be smaller than the height c2 of the precipitation case 310. The height d2 of the baffle 390 is 15 cm.

Meanwhile, the distance between the baffle 390 and the inlet port 311 may be shorter than the distance between the baffle 390 and the outlet port 312. The distance g2 between the center of the inlet port 311 and the baffle 390 is 5 cm, and the distance f2 between the center of the outlet port 312 and the baffle 390 is 7 cm, and the baffle 390 is the inlet port. It is formed close to 311. As such, when the baffle 390 is formed close to the inflow port 311, the flow of water introduced into the inflow port 311 may be effectively prevented.

Precipitating experiment of kitchen filth was performed using the kitchen filth pretreatment device shown in FIG. 6, and the results are shown in Table 2 below.

Kitchen Sewage Pretreatment Outflow Rate (%) Transverse pipe deposition Transverse deposition Uncooked rice 2.6 × × Egg shells 28 × × Chicken bone 69 × × Pickled Chinese Cabbage 100 × × Seaweed 100 × ×

Seaweed and pickled cabbage were discharged into the transverse pipe and the transverse pipe without any internal sedimentation of the kitchen waste pretreatment device 300, and quickly discharged out of the pipe according to the flow of water. Uncooked rice and eggshell crushed was found to be deposited in a significant amount in the kitchen waste pretreatment (300). The most common deposit was raw rice (97.4%), followed by egg shells (72%) and chicken bone (31%). Raw rice, egg shells and chicken bones among the pulverized products discharged from the kitchen waste pretreatment device 300 were smoothly discharged out of the pipe without any deposit in the transverse pipe and the transverse pipe. In the case of egg shells, all ingredients (shells) having a relatively high specific gravity were precipitated in the kitchen waste pretreatment device 300, and since most of the discharged pulverized components were discharged due to fragmentation of the endothelial (membrane) inside the eggs, It can be predicted that they were quickly discharged out of the pipe without depositing in the transverse pipe. In the case of chicken bone grind, pure chicken bone having a large specific gravity was deposited in the kitchen waste pretreatment device 300, but the components of the chicken bone grind leaked out of the kitchen waste pretreatment device 300 are lean meat and cartilage (cartilage) components attached to the chicken bone part. It is judged to be. Therefore, the lean meat and the lump bone were discharged out of the pipe smoothly without depositing in the transverse pipe and the transverse pipe. As a result of the experiment of the kitchen waste pretreatment device 300, raw rice, egg shell, and chicken bone pulverized material having a large specific gravity did not show any deposit phenomenon in the pipe.

In the second embodiment of the kitchen waste pretreatment apparatus 300, the kitchen waste pretreatment apparatus having a reduced size (capacity) was also tested because the volume is 9 liters, which is somewhat large to enter the sink. A variation of the second embodiment of the kitchen waste pretreatment device 300 has a capacity of 5 liters, the width of the bottom of the sedimentation case (a2) 22.5cm, length (b2) 15.5cm, height (c2) 14.5cm It was. The width e2 of the baffle 390 was 12.5 cm, and the height d2 of the baffle 390 was 11 cm. The height h2 of the inlet port 311 is 4 cm, and the height k2 of the outlet port 312 is 7.5 cm. The distance g2 between the center of the inlet port 311 and the baffle 390 is 4.5 cm, and the distance f2 between the center of the outlet port 312 and the baffle 390 is 5.5 cm.

Precipitation experiments were performed using the modified example of the kitchen waste pretreatment apparatus 300 according to the second embodiment, and the results are shown in the following [Table 3].

Kitchen Sewage Pretreatment Outflow Rate (%) Transverse pipe deposition Transverse deposition Uncooked rice 8 × × Egg shells 25 × △ Chicken bone 53 × △ Pickled Chinese Cabbage 100 × × Seaweed 100 × ×

Seaweed and pickled cabbage, which is a relatively light food waste crushed product, were discharged into transverse pipes and transverse pipes without any deposition inside the kitchen waste pretreatment device, and quickly discharged out of the pipes according to the flow of water. In contrast, egg shells and chicken bone grits were found to be deposited on kitchen waste pretreatments in significant amounts. Egg shells and chicken bones were partially deposited in the transverse tubes of the ground pulverized by the kitchen waste pretreatment. In the case of uncooked ground ground, the ground discharged from the kitchen waste pretreatment device was smoothly transferred out of the pipe without any deposit in the pipe.

As can be seen in Table 3, since the modified example of the kitchen waste pretreatment does not filter the egg shells and chicken bones among the crushed materials having a large specific gravity, the experiment was performed using another modified example.

Another variation of the second embodiment of the kitchen waste pretreatment device 300 has a capacity of 5 liters, while the width a2 of the bottom of the precipitation case is 12.5 cm and the length b2 of 12.5 cm, while the height c2 Was 24.5 cm. The width e2 of the baffle 390 was 11.5 cm, and the height d2 of the baffle 390 was 21 cm. The height h2 of the inlet port 311 is 13 cm, and the height k2 of the outlet port 312 is 20 cm. Precipitation experiments were performed using other modifications of the kitchen waste pretreatment device 300 according to the second embodiment, and the results are shown in Table 4 below.

Kitchen Sewage Pretreatment Outflow Rate (%) Transverse pipe deposition Transverse deposition Uncooked rice 6 △ × Egg shells 29 ○ × Chicken bone 50 × △ Pickled Chinese Cabbage 100 × × Seaweed 100 × ×

Seaweed and pickled cabbage, which is a relatively light food waste crushed product, were discharged into transverse pipes and transverse pipes without any deposition inside the kitchen waste pretreatment device, and quickly discharged out of the pipes according to the flow of water. In contrast, egg shells and chicken bone grits were found to be deposited in kitchen waste pretreatment. Some of the raw rice and egg shells of the ground discharged from the kitchen waste pretreatment were deposited in the transverse tube.

7 is a view schematically showing a third embodiment of the kitchen waste pretreatment apparatus according to the present invention. In the kitchen waste pretreatment apparatus 400 illustrated in FIG. 7, the baffle 490 may be formed in a direction parallel to the sidewall on which the inlet port 411 is formed and the sidewall on which the outlet port 412 is formed. That is, the baffle 490 is formed in the same direction as the sidewall on which the inlet port 411 is formed and the sidewall on which the outlet port 412 is formed, and is located between the inlet port 411 and the outlet port 412. As such, by forming the baffle 490, the flow of water introduced through the inlet port 411 may be blocked by the baffle 490, thereby precipitating the pulverized kitchen soil having a large specific gravity.

The approximate shape of the precipitation case 410 may be referred to as a rectangular parallelepiped shape. The capacity of the precipitation case 410 was 5 liters, and the width (a3) of the bottom (bottom) was 19 cm, the length (b3) was 13 cm, and the height (c3) was 21 cm. The diameters i3 and j3 of the inlet port 411 and the outlet port 412 are all 5 cm, the height l3 of the center of the inlet port 411 is 12 cm, and the height k3 of the center of the outlet port 412 is 16 cm. The outlet port 412 is formed higher than the inlet port 411.

The distance between the baffle 490 and the inlet port 411 may be shorter than the distance between the baffle 490 and the outlet port 412. The distance g3 between the side wall on which the inlet port 411 is formed and the baffle 490 is 7 cm, and the distance h3 between the side wall on which the outlet port 412 is formed and the baffle 490 is 12 cm. Is close to the inlet port 411.

In the case of the kitchen waste pretreatment apparatus 400 according to the third embodiment, the baffle 490 may be spaced apart from the bottom of the precipitation case 410. That is, there is a gap f3 of about 3 cm between the bottom of the baffle 490 and the bottom of the precipitation case 410. Water flows through this gap. On the other hand, the width e3 of the baffle 490 is 13 cm, and the height d3 of the baffle 490 is also 13 cm.

Precipitation experiments were performed using the kitchen waste pretreatment device 400 shown in FIG. 7, and the results are shown in Table 5 below.

Kitchen Sewage Pretreatment Outflow Rate (%) Transverse pipe deposition Transverse deposition Uncooked rice 25 △ × Egg shells 29 △ × Chicken bone 71 × △ Pickled Chinese Cabbage 100 × × Seaweed 100 × ×

Seaweed and pickled cabbage, which are relatively light food waste crushed ingredients, were discharged into the transverse pipe and the transverse pipe without any deposition inside the kitchen waste pretreatment device 400, and quickly discharged out of the pipe according to the flow of water. On the other hand, egg shells and chicken bone pulverization appeared to be deposited in a considerable amount in the kitchen waste pretreatment (400). Some of the uncooked rice and egg shells of the pulverized product discharged from the kitchen waste pretreatment device 400 were deposited in the transverse tube. In addition, the chicken bone grinds passed through the transverse tube, but some deposition was observed in the transverse tube.

Experiments were also carried out for the modified example in which the size of the kitchen waste pretreatment apparatus 400 according to the third embodiment shown in FIG. 7 was changed.

That is, the baffle 590 is spaced about 3 cm from the side wall facing the side wall on which the outlet port 512 is formed. Water flows through this gap. The width e4 of the baffle 590 is 5 cm, and the height d4 of the baffle 590 is 19 cm. As such, the height d4 of the baffle 590 may be smaller than the height c4 of the precipitation case 510.

Meanwhile, the distance g4 between the baffle 590 and the sidewall on which the inlet port 511 is formed may be longer than the distance h4 between the baffle 590 and the center of the outlet port 512. The distance g4 between the baffle 590 and the sidewall on which the inlet port 511 is formed is 6.5 cm, and the distance h4 between the baffle 590 and the center of the outlet port 512 is 6 cm. It may be formed near the outlet port 512.

Kitchen Sewage Pretreatment Outflow Rate (%) Transverse pipe deposition Transverse deposition Uncooked rice 2 × × Egg shells 30 × × Chicken bone 72 × × Pickled Chinese Cabbage 100 × × Seaweed 100 × ×

Seaweed and pickled cabbage, which is a relatively light food waste crushed component, was discharged into the transverse pipe and the transverse pipe without any deposition inside the kitchen waste pretreatment device 500, and quickly discharged out of the pipe according to the flow of water. On the other hand, egg shells and chicken bone pulverization appeared to be deposited in a significant amount in the kitchen waste pretreatment (500). Raw rice, egg shells and chicken bones among the pulverized products discharged from the kitchen waste pretreatment device 500 were discharged smoothly out of the pipe without any deposit in the transverse pipe and the transverse pipe. In the case of egg shells, all ingredients (shells) having a relatively high specific gravity were precipitated in the kitchen waste pretreatment device 500, and since most of the discharged pulverized components were discharged by crushing the endothelial (membrane) inside the eggs, It is believed that the pipes were quickly discharged out of the pipes without deposition on the transverse pipes. In the case of chicken bone grind, pure chicken bone having a large specific gravity was deposited in the kitchen waste pretreatment device 500, but the components of the chicken bone grind spilled out of the kitchen waste pretreatment device 500 are lean meat and cartilage (cartilage) components attached to the chicken bone part. It is judged to be. Therefore, the lean meat and the lump bone were discharged out of the pipe smoothly without deposition on the transverse pipe and the transverse pipe. Experimental results of the kitchen waste pretreatment device 500, it can be seen that the raw material, egg shells, chicken bone pulverized material having a large specific gravity did not show any deposition phenomenon in the pipe.
