Description

[Technical field]

[0001] The present invention relates to a food waste processing apparatus which crushes food waste and releases the crushed food waste into a sewer. [Background technology]

[0002] There is a known garbage disposer that crushes kitchen waste and produces a slurry. The slurry discharged from the garbage disposer is discharged into a public sewer system, but if the crushed food waste particles contained in the slurry are coarse, the slurry may clog the sewer system. To solve this problem, attempts have been made to improve the structure of the garbage disposer and to make the crushed food waste particles contained in the slurry finer.

[0003] For example, Patent Document 1 discloses a food waste processor that includes an inner rotary blade, an inner fixed blade, an outer rotary blade, and an outer fixed blade, and that crushes food waste crushed by the inner rotary blade and the inner fixed blade, and then crushes the food waste by the outer rotary blade and the outer fixed blade. This food waste processor can crush food waste that has been crushed once again, and therefore can turn the crushed waste into fine particles.

[0004] Patent Document 2 discloses a disposer equipped with a crushing plate equipped with a hammer, a fixed blade, and a rotating blade. According to this disposer, the food waste crushed by the crushing plate is pinched between the crushing plate and the fixed blade and crushed. The crushed food waste is cut by the rotating blade. Therefore, according to this disposer, it is said that the food waste can be crushed into such fine particles that its presence is not felt at all. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 63-84651 [Patent Document 2] Japanese Patent Application Publication No. 7-194991 Summary of the Invention [Problem to be solved by the invention]

[0006] The disposers described in the cited documents 1 and 2 may be able to break down food waste into fine particles and prevent clogging of sewer pipes, etc. However, the disposers described in the cited documents 1 and 2 have a complex structure, which makes them susceptible to clogging inside the disposers.

[0007] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a food waste treatment device that can break down food waste into fine particles to prevent clogging of sewer pipes, etc., and that is less likely to cause clogging inside the food waste treatment device. [Means for solving the problem]

[0008] The kitchen waste processing apparatus of the present invention comprises a first disposer that receives kitchen waste discharged from a kitchen and crushes it, a solid-liquid separation device that receives slurry discharged from the first disposer and separates the slurry into solid and liquid components, a second disposer that receives solid components discharged from the solid-liquid separation device and crushes the solid components again, a return pipeline that returns the slurry discharged from the second disposer to the solid-liquid separation device, and a discharge pipeline that discharges liquid components discharged from the solid-liquid separation device to the outside.

[0009] The kitchen waste processing apparatus of the present invention comprises a first disposer that receives kitchen waste discharged from a kitchen and crushes it, a second disposer that receives slurry discharged from the first disposer and re-crushes the solid components contained in the slurry, a solid-liquid separation device that receives slurry discharged from the second disposer and separates the slurry into solid and liquid components, a guide means that guides the solid components discharged from the solid-liquid separation device back to the second disposer, and a discharge pipeline that discharges the liquid components discharged from the solid-liquid separation device to the outside.

[0010] A grease trap may be provided downstream of the discharge pipe to capture oily components contained in the liquid components discharged from the drain pipe.

[0011] The apparatus may also include an oil treatment tank in which an enzyme is applied to the liquid component discharged from the solid-liquid separation device to promote decomposition of oils and fats contained in the liquid component.

[0012] A grease trap may be provided downstream of the oil treatment tank to capture oil and fat components contained in the liquid components discharged from the oil treatment tank.

[0013] The second disposer may be provided with an opening drilled in the casing for discharging solid components fed into the second disposer before the solid components are crushed by the second disposer, an opening / closing lid for opening and closing the opening, and a solid component recovery box for receiving solid components discharged outside the casing through the opening.

[0014] The solid component collection box may include a drain basket that separates moisture that flows into the solid component collection box together with the solid components from the solid components, and a drain outlet that discharges the moisture separated from the solid components in the drain basket to the outside. Effect of the Invention

[0015] According to the present invention, the slurry discharged from the first disposer is circulated between the solid-liquid separator and the second disposer, so that the solid components contained in the slurry can be repeatedly pulverized. This promotes atomization of the solid components. As a result, the fluidity of the slurry discharged from the food waste processing device increases, so that clogging in the sewer system is suppressed. In addition, the food waste processing device can be constructed using a conventional disposer that has a proven track record in reliability, so clogging is less likely to occur inside the food waste processing device, especially inside the disposer.

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A wastewater treatment device according to an embodiment of the present invention will now be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are designated by the same reference numerals.

[0018] [First embodiment] [Basic configuration] FIG. 1 is a configuration diagram of a food waste processing device 1 according to a first embodiment of the present invention. As shown in FIG. 1, the food waste processing device 1 is fixed under a sink 3 arranged in a kitchen 2 and includes a first disposer 4 for receiving food waste dropped into the sink 3, i.e., food waste discharged from the kitchen 2. The first disposer 4 is a known device for crushing food waste to generate and discharge a slurry. The slurry discharged from the first disposer 4 is pressurized by a pump 5 and sent through a delivery pipe 6 toward a food waste processing unit 7. The food waste processing unit 7 is a housing that houses a solid-liquid separator 8, a second disposer 9, and other devices, which will be described later.

[0019] As shown in FIG. 1, the slurry discharged through the delivery pipe 6 flows into the lower part of the solid-liquid separator 8. The solid-liquid separator 8 is a known device including a cylindrical screen tube 8a, a screw conveyor 8b disposed inside the screen tube 8a, and an electric motor 8c for rotating the screw conveyor 8b. The screen tube 8a is a cylindrical member having a number of through holes (not shown), and the screw conveyor 8b is a mechanical part formed by fixing a spiral blade member around a cylindrical shaft member. When the screw conveyor 8b is rotated by the electric motor 8c, the slurry that flows into the lower part of the solid-liquid separator 8 is transported toward the upper part of the screen tube 8a. In addition, a pressing lid 8d is disposed at the upper end of the screen tube 8a. The pressing lid 8d is biased in a direction to close the upper end of the screen tube 8a by a spring (not shown). For a detailed configuration of the solid-liquid separator 8, please refer to JP 2016-120453 A, if necessary.

[0020] [Slurry circulation and generation and discharge of fine particles] As described above, the slurry that has flowed into the lower part of the solid-liquid separator 8 is pushed up toward the upper end of the screen cylinder 8a by the screw conveyor 8b. Since the upper end of the screen cylinder 8a has a pressing lid 8d, the slurry is compressed by being sandwiched between the screw conveyor 8b and the pressing lid 8d. When the slurry is compressed, the liquid components contained in the slurry are squeezed out of the slurry. The liquid components squeezed out of the slurry are discharged to the outside of the screen cylinder 8a through a number of through holes drilled in the screen cylinder 8a. In this embodiment, since the diameter of the through holes provided in the screen cylinder 8a is about 2 mm, among the solid components contained in the slurry, solid particles having a particle size of less than 2 mm are discharged to the outside of the screen cylinder 8a together with the liquid components. Hereinafter, in this specification, solid particles having a particle size of less than 2 mm that pass through the through holes provided in the screen cylinder 8a will be referred to as "fine particles".

[0021] The liquid components and fine particles discharged outside the screen tube 8a through the above process are discharged outside the solid-liquid separator 8 through the drain port 8e. The liquid components and fine particles discharged outside the solid-liquid separator 8 are discharged into the sewer through the discharge pipe 10 and the grease trap 11. The grease trap 11 is a known device that is disposed downstream of the discharge pipe 10 and uses the difference in specific gravity between water and oil to capture oil contained in the wastewater and prevent the oil from being discharged into the sewer. As shown in FIG. 1, the grease trap 11 is equipped with a dust trap 11a to prevent foreign matter from being discharged into the sewer. The mesh of the dust trap 11a is about 5 mm, so fine particles with a particle size of less than 2 mm can easily pass through the dust trap 9a.

[0022] On the other hand, the remaining solid components after the liquid components and fine particles are squeezed out of the slurry are pushed up the pressing lid 8d and discharged from the upper end of the solid-liquid separator 8. Also, as shown in FIG. 1, a duct 12 is provided between the solid-liquid separator 8 and the second disposer 9. The duct 12 is an example of the guide means in the present invention, and is a pipe that prevents the solid components discharged from the upper end of the solid-liquid separator 8 from scattering and guides the solid components to the second disposer 9. Therefore, the solid components discharged from the upper end of the solid-liquid separator 8 are guided to the duct 12 and fall toward the second disposer 9. Also, a washing shower 12a is provided in the duct 12. The washing shower 12a is a device that sprays water inside the duct 12. The washing shower 12a can add water to the solid components discharged from the upper end of the solid-liquid separator 8 to return them to a slurry. Also, the washing shower 12a can wash the inner surface of the duct 12 with water.

[0023] The second disposer 9 is a device that crushes and discharges solid components contained in the slurry. The basic configuration and operation of the second disposer 9 are publicly known and are the same as those of the first disposer 4. The unique configuration and operation of the second disposer 9 will be described later. As shown in FIG. 1, a solid component recovery box 13 is disposed adjacent to the second disposer 9. The solid component recovery box 13 is a device that recovers solid components that are difficult to atomize in the food waste processing device 1. The configuration and operation of the solid component recovery box 13 will be described later.

[0024] The solid components contained in the slurry that flows from the solid-liquid separator 8 through the duct 12 into the second disposer 9 are crushed again in the second disposer 9. As shown in FIG. 1, a reflux line 14 is provided between the second disposer 9 and the solid-liquid separator 8. Therefore, the slurry that has been crushed in the second disposer 9 is transported to the solid-liquid separator 8 through the reflux line 14.

[0025] As configured as above, the slurry circulates between the solid-liquid separator 8 and the second disposer 9. While circulating between the solid-liquid separator 8 and the second disposer 9, the crushing process is repeated in the second disposer 9, promoting the generation of fine particles. The fine particles are then discharged from the solid-liquid separator 8 and discharged together with the liquid components into the sewer. During the repeated circulation, most of the solid components contained in the slurry become fine particles and are discharged into the sewer.

[0026] [Recovery of solid components that are difficult to atomize] However, the food waste processed by the food waste processing device 1 may contain solid components, such as fibrous matter, that are difficult to atomize. In this case, even if the crushing process by the second disposer 9 is repeated, it is not possible to atomize all of the solid components and discharge them into the sewer. The solid components that are difficult to atomize remain in the circulation path between the solid-liquid separator 8 and the second disposer 9. As described above, the solid components that are difficult to atomize are collected by the solid component collection box 13. The mechanism for collecting the solid components that are difficult to atomize will be described below.

[0027] FIG. 2 is an explanatory diagram showing the detailed configuration of the second disposer 9 and the solid component recovery box 13. As shown in FIG. 2, the second disposer 9 includes a casing 9a and an electric motor 9b. The electric motor 9b is disposed below the casing 9a and fixed to the casing 9a. Inside the casing 9a, a rotating disk 9c that is driven to rotate by the electric motor 9b and a swing hammer 9d that is pivoted to the rotating disk 9c and swings freely relative to the rotating disk 9c are disposed. A fixed blade 9e is disposed around the rotating disk 9c, and the fixed blade 9e is fixed to the casing 9a. The shapes of the swing hammer 9d and the fixed blade 9e will be described later.

[0028] With this configuration, when the slurry is fed into the casing 9a, the slurry falls onto the rotating disk 9c. When the slurry falls onto the rotating disk 9c, the solid components contained in the slurry are pinched between the swing hammer 9d and the fixed blade 9e and crushed. In other words, the solid components are pulverized. The pulverized solid components are discharged to the outside of the casing 9a through the discharge port 9f together with the liquid components.

[0029] As described above, the basic configuration and operation of the second disposer 9 are the same as those of the first disposer 4. In other words, the configuration and operation of the second disposer 9 are the same as those of the first disposer 4. However, as shown in Fig. 2, an opening 9g is provided in the casing 9a of the second disposer 9. In this respect, the second disposer 9 differs from the first disposer 4.

[0030] 2, a solid component recovery box 13 is disposed beside the casing 9a of the second disposer 9 and is fixed to the casing 9a. The internal space of the solid component recovery box 13 and the internal space of the casing 9a are connected through an opening 9g. In other words, objects can be moved between the casing 9a and the solid component recovery box 13 through the opening 9g.

[0031] 2, the solid component recovery box 13 is provided with an opening / closing lid 13a. The opening / closing lid 13a is a lid that can be opened and closed by an operator, and during normal operation of the food waste processing device 1, the opening / closing lid 13a is placed over the opening 9g and closes the opening 9g. As described below, the opening / closing lid 13a is moved away from the opening 9g as necessary. In other words, the opening 9g is opened as necessary.

[0032] 2, a collection basket 13b is disposed inside the solid component collection box 13. The collection basket 13b is a metal container that can be removed from the solid component collection box 13 as needed, and has an open top. A number of drain holes 13c are formed in the side and bottom of the collection basket 13b. The bottom of the solid component collection box 13 is also provided with a drain outlet 13d.

[0033] As described above, the opening / closing lid 13a is operated as necessary to move away from the opening 9g. As a result, the opening 9g is opened. When the opening 9g is opened, the slurry put into the second disposer 9 is bounced off the rotating rotary disk 9c and flows through the opening 9g into the solid component recovery box 13. In this way, when the opening 9g is opened, the slurry put into the second disposer 9 is discharged outside the second disposer 9 through the opening 9g before being crushed, and is received in the solid component recovery box 13.

[0034] The slurry flowing into the solid component recovery box 13 is received by the recovery basket 13b. The liquid components contained in the slurry received by the recovery basket 13b are discharged to the outside through the drainage holes 13c and the drainage outlet 13d. The solid components contained in the slurry remain in the recovery basket 13b. In this way, the recovery basket 13b functions as a drain basket that separates the liquid components that flow into the solid component recovery box 13 together with the solid components from the solid components.

[0035] As described above, even if the operation of the food waste processing device 1 is continued and the slurry is repeatedly circulated between the solid-liquid separator 8 and the second disposer 9, some of the solid components that are difficult to atomize may remain in the circulation path between the solid-liquid separator 8 and the second disposer 9. In such a case, by operating the opening / closing lid 13a to open the opening 9g, the solid components remaining in the circulation path between the solid-liquid separator 8 and the second disposer 9 can be removed from the circulation path and received in the recovery basket 13b. The solid components received in the recovery basket 13b can be disposed of appropriately. In other words, the solid components that are difficult to atomize in the food waste processing device 1 can be collected.

[0036] The timing and means for operating the opening / closing lid 13a to open the opening 9g are not particularly limited. An operator in charge of maintaining the food waste processing device 1 may visually check the state of the food waste processing device 1 and manually operate the opening / closing lid 13a as necessary. Alternatively, the food waste processing device 1 may be provided with a timer so that the opening / closing lid 13a is automatically opened every time a certain operating time has elapsed. Alternatively, a sensor for detecting the amount of slurry circulating between the solid-liquid separator 8 and the second disposer 9 may be provided so that the opening / closing lid 13a is automatically opened when the amount of slurry exceeds a predetermined value.

[0037] [Second embodiment] 3 is a configuration diagram of a food waste processing device 1 according to a second embodiment of the present invention. The basic configuration and operation of the food waste processing device 1 according to the second embodiment are common to the food waste processing device 1 according to the first embodiment, so the following will explain the differences.

[0038] In the food waste processing device 1 according to the first embodiment, the slurry discharged from the first disposer 4 is pressurized by the pump 5 and flows into the lower part of the solid-liquid separator 8, whereas in the food waste processing device 1 according to the second embodiment, as shown in Fig. 2, the slurry discharged from the first disposer 4 and pressurized by the pump 5 flows into the second disposer 9. In this respect, the food waste processing device 1 according to the second embodiment differs from the food waste processing device 1 according to the first embodiment.

[0039] Other configurations and operations are common between the food waste processing device 1 according to the second embodiment and the food waste processing device 1 according to the first embodiment. That is, in the food waste processing device 1 according to the second embodiment, the slurry that has been pulverized in the second disposer 9 also flows into the lower part of the solid-liquid separator 8 and undergoes solid-liquid separation. Moisture is added again to the solid components separated from the slurry as a result of solid-liquid separation, and the solid components are fed into the second disposer 9. While the slurry circulates between the second disposer 9 and the solid-liquid separator 8, the solid components contained in the slurry are atomized. The atomized solid components are separated from the slurry together with the liquid components in the solid-liquid separator 8 and discharged. Solid components that are difficult to atomize in the solid-liquid separator 8 are transferred to the solid component recovery box 13 as necessary and recovered there.

[0040] [Third embodiment] 4 is a configuration diagram of the food waste processing device 1 according to the second embodiment of the present invention. The basic configuration and operation of the food waste processing device 1 according to the third embodiment are common to the food waste processing device 1 according to the first embodiment, so the following will explain the differences.

[0041] In the first embodiment, the liquid components and the finely divided solid components discharged from the solid-liquid separator 8 and the solid component recovery box 13 are discharged directly into the grease trap 11 through the discharge pipe 10. In contrast, the kitchen waste processing device 1 according to the third embodiment includes an oil processing tank 15 between the solid-liquid separator 8 and the solid component recovery box 13 and the grease trap 11, as shown in FIG.

[0042] The oil treatment tank 15 is a device that promotes the decomposition of oil and fat components contained in the wastewater by acting an enzyme preparation derived from a living organism on the wastewater. As shown in FIG. 4, the oil treatment tank 15 is provided with an enzyme preparation inlet 15a for introducing an enzyme preparation supplied from an enzyme preparation tank (not shown) into the oil treatment tank 15, and an air inlet 15b for blowing air supplied from an air source (not shown) into the oil treatment tank 15. The liquid components and the finely divided solid components discharged from the solid-liquid separator 8 and the solid component recovery box 13 flow into the oil treatment tank 15 from the bottom of the oil treatment tank 15. In the oil treatment tank 15, the liquid components and the finely divided solid components are mixed with the enzyme preparation. The action of the enzyme preparation is promoted by blowing air into the tank. As a result, the oil and fat contained in the liquid components and the finely divided solid components are decomposed. The liquid components and the finely divided solid components that have completed the decomposition process of the oil and fat are discharged from the top of the oil treatment tank 15 and flow into the grease trap 11. 4, a pump 16 is disposed between the solid-liquid separator 8 and the solid component recovery box 13, and the oil treatment tank 15. The liquid components and the finely divided solid components discharged from the solid-liquid separator 8 and the solid component recovery box 13 are pressurized by the pump 16 and flow into the oil treatment tank 15.

[0043] In this way, the kitchen waste processing device 1 according to the third embodiment is provided with the oil processing tank 15 upstream of the grease trap 11, so that the amount of oil contained in the wastewater flowing into the grease trap 11 is reduced. Therefore, the amount of oil captured by the grease trap 11 is reduced, so that the frequency of cleaning the grease trap 11 can be reduced.

[0044] In the above, an example in which the oil treatment tank 15 is added to the food waste processing device 1 according to the first embodiment has been shown, but the oil treatment tank 15 may be added to the food waste processing device 1 according to the second embodiment. In this case, the same effect can be obtained. Furthermore, the specific configuration or properties of the enzyme preparation are not limited. Any enzyme preparation that acts on fats and oils and promotes the decomposition of fats and oils is sufficient, and various known substances can be selected and used as desired. Alternatively, the food waste processing device 1 may be provided with a culture tank for culturing microorganisms, and the enzymes produced by the microorganisms in the culture tank may be introduced into the oil treatment tank 15.

[0045] [Details of the disposer] Fig. 5(A) is a plan view showing a part of the fixed blade 4e and the shape of the swing hammer 4d of the first disposer 4, that is, a view of a part of the fixed blade 4e and the swing hammer 4d seen from the direction indicated by the arrow A in Fig. 1. Fig. 5(B) is a plan view showing a part of the fixed blade 9e and the shape of the swing hammer 9d of the second disposer 9, that is, a view of a part of the fixed blade 9e and the swing hammer 9d seen from the direction indicated by the arrow B in Fig. 1.

[0046] As described above, in the first and second embodiments, the basic configuration of the first disposer 4 and the second disposer 9 is the same, but the detailed configuration may be changed. For example, as shown in FIG. 5(A), the groove width of the fixed blade 4e may be 6 mm and the groove depth may be 3 mm, and as shown in FIG. 5(B), the groove width of the fixed blade 9e may be 2 mm and the groove depth may be 2 mm. In the first disposer 4, the groove width and groove depth of the fixed blade 4e are large, so the particles obtained by the crushing process become coarse, but the crushing process speed can be increased. In the second disposer 9, the groove width and groove depth of the fixed blade 9e are large, so the crushing process speed decreases, but the particles obtained by the crushing process can be finer.

[0047] [summary] As described above, according to the garbage disposal device 1 of the first and second embodiments, the slurry discharged from the first disposer 4 is circulated between the solid-liquid separator 8 and the second disposer 9, so that the solid components contained in the slurry can be repeatedly crushed. The crushing process of the solid components contained in the slurry is repeated, so that the solid components are promoted to be finely divided. The first disposer 4 and the second disposer 9 can be made of a known configuration that has a proven track record and is highly reliable, so clogging is unlikely to occur.

[0048] According to the food waste processing device 1 of the first and second embodiments, as necessary, by operating the opening / closing lid 13a to open the opening 9g, solid components that are difficult to atomize and remain in the circulation path between the solid-liquid separation device 8 and the second disposer 9 can be guided to the solid component recovery box 13 and recovered.

[0049] However, the first and second embodiments are merely examples of specific configurations of the food waste processing device according to the present invention, and the technical scope of the present invention is not limited by the first and second embodiments. The present invention can be freely applied, modified, or improved within the scope of the technical ideas described in the claims.

[0050] In particular, the specific mechanical configurations of the first and second disposers and the solid-liquid separator are not limited to the first disposer 4, the second disposer 9, and the solid-liquid separator 8 shown in the first and second embodiments. The first and second disposers and the solid-liquid separator can be designed arbitrarily. It goes without saying that the shape and dimensions of the fixed blade shown in Figure 5 are merely examples.

[0051] Although the duct 12 is shown as a specific example of the guiding means in the present invention, the specific form of the guiding means is not limited by the duct 12. It is sufficient for the guiding means to have a function of guiding the solid components discharged from the solid-liquid separator to the second disposer. As long as it has such a function, the specific form of the guiding means can be selected arbitrarily.

[0052] In the first and second embodiments, an example has been shown in which the solid-liquid separator 8, the second disposer 9, the solid component recovery box 13, etc. are housed in the food waste treatment unit 7, but the food waste treatment device according to the present invention is not limited to one having a housing for housing the solid-liquid separator, etc. The solid-liquid separator, etc. may be installed separately in a building. Alternatively, the solid-liquid separator, etc. may be installed in a separate section of the building in which the kitchen is located. If there are no hygiene management issues, the solid-liquid separator, etc. may be installed in the same section as the kitchen, that is, in the kitchen.

[0053] In the first and second embodiments, an example is shown in which the first disposer 4, the solid-liquid separator 8, and the second disposer 9 are provided, but the configuration of the food waste processing device according to the present invention is not limited to this. The food waste processing device according to the present invention may be provided with a plurality of any one or all of the first disposer, the solid-liquid separator, and the second disposer. The food waste processing device according to the present invention may be configured such that a slurry circulation path is formed by one solid-liquid separator and one second disposer, and slurries discharged from a plurality of first disposers flow into the circulation path. The slurry circulation path may be formed by a plurality of solid-liquid separators and a plurality of second disposers. [Explanation of symbols]
