[0002] Garbage, especially food waste, contains a lot of grease in the remaining sewage except for the solid residue. If the oil and water are not separated sufficiently, the residual grease will lead to a decline in the subsequent sewage treatment effect.

[0003] Among the many ways to treat food waste and sewage, the separation of oil and water is the most important.

[0004] The existing publication number is CN113441531B, which discloses a restaurant kitchen waste pretreatment system and method, the system comprising: a pulping machine, the pulping machine comprising a pulping chamber, a rotor arranged in the pulping chamber, a restaurant kitchen waste inlet and a slag discharge port arranged on the wall of the pulping chamber, and a sieve plate arranged at the bottom opening of the pulping chamber, a drain port being arranged below the sieve plate; a sand removal system connected to the drain port of the pulping machine; a sterilization device connected to the drain port of the sand removal system; a three-phase centrifuge connected to the discharge port of the sterilization device, and used to separate the material from the sterilization device into a water phase, an oil phase and slag.

[0005] The prior art has the following problems:

[0006] In terms of the transportation and storage costs of food waste, it is not suitable for long-distance transportation and long-term storage. In order to save processing energy, it is often necessary to collect all the food waste of the day and treat it in a unified manner. This will cause the food waste collected first to emit volatile smelly gases and seepage during the storage process, polluting the environment. Summary of the invention

[0007] The present invention provides a garbage sewage water separation device and treatment process, which can solve the technical problem that the sewage treatment system of food waste in the prior art uses a three-phase centrifuge for separation, which pollutes the environment due to the volatile odorous gas and seepage of the food waste collected in advance during the storage process.

[0008] In order to achieve the above object, the present invention is implemented by the following technical solutions:

[0009] The present application provides a garbage sewage water separation device, which includes a freezing chamber and a slicer. The freezing chamber has a storage barrel and a refrigeration component. The refrigeration component is disposed around the outer side of the storage barrel. The storage barrel is used to hold the swill transported by a transfer barrel and let it stand for stratification. After the swill stands, it is stratified into a waste residue layer, a waste water layer and a waste oil layer. The refrigeration component freezes the waste residue layer, the waste water layer and the waste oil layer; the slicer has a band saw, and the band saw is used to cut the frozen waste residue layer, waste water layer and waste oil layer.

[0010] Through the above technical solution, by using the combination of the storage barrel and the refrigeration component, batch-by-batch and quantity-by-quantity immediate freezing treatment can be carried out for different batches of kitchen waste, effectively avoiding environmental pollution caused by the volatilization of malodorous gases and seepage liquid from kitchen waste; at the same time, as the first treatment process of kitchen waste, through the method of freezing and screening, the diffusion of the odor of kitchen waste is effectively reduced, the growth of bacteria is also reduced, and the hygienic safety of the entire treatment system is improved.

[0011] In the present invention, the above freezing chamber further includes an ultrasonic component. The ultrasonic component has a plurality of transducers, and the transducers are abutted against the bottom of the storage barrel.

[0012] Through the above technical solution, by using the cavitation effect generated by ultrasonic waves, the separation efficiency of waste residue and waste oil in kitchen waste is enhanced, and the utilization efficiency of waste oil in kitchen waste is improved.

[0013] In the present invention, the above refrigeration component includes a semiconductor refrigeration sheet and a heat dissipation water pipe. The semiconductor refrigeration sheet has a cold surface and a hot surface. The cold surface is abutted against the outer side wall of the storage barrel, and a heat dissipation plate is abutted against the hot surface; the heat dissipation water pipe is connected to the side of the heat dissipation plate背离 the semiconductor refrigeration sheet.

[0014] Through the above technical solution, by using the semiconductor refrigeration sheet for refrigeration, the refrigeration efficiency is improved, the harmful by-products generated by refrigeration are reduced, and the environmental protection of refrigeration is improved; at the same time, the hot water generated by heat dissipation can be recycled for further utilization, improving the energy utilization efficiency.

[0015] In the present invention, the above garbage sewage water separation device further includes a water bath pool. The water bath pool is used to hold the waste oil layer. The water bath pool melts the waste oil layer by means of water bath heating and evaporates the residual water in the waste oil layer at a low temperature. The water bath pool is communicated with the heat dissipation water pipe.

[0016] Through the above technical solution, by using the method of water bath heating and evaporation, the hot water generated by the heat dissipation of the semiconductor refrigeration sheet is fully utilized to heat the waste oil, saving energy; at the same time, it also avoids the deterioration of the oil products to a certain extent and reduces the water content of the oil products.

[0017] In the present invention, the garbage sewage water separation device further includes a thawing pool for holding the wastewater layer. The thawing pool is provided with a plurality of heat pipes which are communicated with the water bath pool and abut against the wastewater layer to melt the wastewater layer.

[0018] By the above technical solution, the warm water discharged from the water bath pool is used to thaw the frozen wastewater layer, shortening the waiting time for wastewater treatment and avoiding the use of additional heat sources, thus improving the energy-saving effect and treatment efficiency.

[0019] In the present invention, the above heat pipes include a first heat pipe and a second heat pipe. The first heat pipe is connected in a V shape inside the thawing pool; the second heat pipe is connected inside the thawing pool and is parallel to the bottom surface of the thawing pool.

[0020] By the above technical solution, the V-shaped first heat pipe is used to quickly melt and decompose the large frozen wastewater layer into small pieces of frozen wastewater, which further fall to the bottom of the thawing pool. Then, the small pieces of frozen wastewater are fully thawed by the second heat pipe at the bottom, making full use of the warm water to melt the wastewater layer.

[0021] This application also provides a garbage sewage water separation and treatment process, which uses the above garbage sewage water separation device and further includes the following steps:

[0022] Step S1: Pour the swill transported by the transfer bucket into the storage bucket for static stratification.

[0023] Step S2: Freeze the stratified swill in the storage bucket through the cold surface of the semiconductor refrigeration sheet, cool the hot surface of the semiconductor refrigeration sheet by circulating water through the heat dissipation water pipe, and generate hot water.

[0024] Step S3: Divide the stratified and frozen swill by a cutting machine. The frozen wastewater layer is sent to the thawing pool for thawing and then discharged into the biological filter for biochemical treatment. The frozen waste oil layer is sent to the water bath pool. The waste oil layer melts in the water bath pool and undergoes low-temperature evaporation to remove residual moisture, and the waste oil after removing moisture is discharged into the storage oil tank for storage.

[0025] By the above technical solution, static stratification and freezing are adopted, reducing the energy consumption of kitchen waste sorting. At the same time, due to the low-temperature and solid-state treatment method of kitchen waste, the environmental pollution in the pretreatment stage is reduced, and the environmental friendliness of the process flow is improved.

[0026] In the present invention, in the above step S3, the hot water used in the water bath pool comes from the hot water discharged from the heat dissipation water pipe in the above step S2. The hot water forms warm water after heating and melting the waste oil layer and performing low-temperature evaporation in the water bath pool.

[0027] Through the above technical solution, the heat in the entire device is fully utilized through water circulation, thereby improving the energy saving effect.

[0028] In the present invention, in the above step S3, warm water discharged from the water bath is introduced into heat pipe 1 and heat pipe 2 in the thawing pool, and the warm water becomes cold water after passing through heat pipe 1 and heat pipe 2. The cold water circulates back to the heat dissipation water pipe to continue to cool the hot surface of the semiconductor refrigeration plate.

[0029] Through the above technical solution, the cold water circulated in the thawing pool is used to cool the hot surface of the semiconductor refrigeration plate, thereby further improving the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Example:

[0048] Please refer to Figures 1 to 11 , Figures 1 to 11 which shows an embodiment of the present application.

[0049] This embodiment provides a garbage sewage separation device. As Fig.11 shown, it includes a freezing bin 1 and a slicer 2. As Figure 2 shown, the freezing bin 1 has a storage barrel 101 and a refrigeration component 102. The refrigeration component 102 is disposed around the outside of the storage barrel 101. The storage barrel 101 is used to hold the swill 401 transported by the transfer barrel 4 and let it stand for stratification. After the swill 401 stands, it is stratified into a waste residue layer 402, a waste water layer 404, and a waste oil layer 405. The refrigeration component 102 freezes the waste residue layer 402, the waste water layer 404, and the waste oil layer 405. The slicer 2 has a band saw, and the band saw is used to cut the frozen waste residue layer 402, waste water layer 404, and waste oil layer 405.

[0050] During use, the transfer vehicle collects the kitchen waste from各处 in the community through the transfer barrel 4. Exemplarily, it is the Figure 2 shown swill 401, and then transports it to the treatment station. Then, the staff pours the swill 401 in the transfer barrel 4 into the storage barrel 101 buried underground. After a certain period of stratification, a waste residue layer 402, a waste water layer 404, and a waste oil layer 405 are formed. The refrigeration component 102 is started to freeze the three layers. After the solid and liquid in the storage barrel 101 are frozen, as Figure 4 shown, use the large hook of the crane to connect the lifting lug 1011 to lift the storage barrel 101 out of the pit. Then, use the small hook to connect the turning groove 1012 at the bottom of the storage barrel 101, raise the small hook to place the storage barrel 101 horizontally, and then knock on the barrel wall to pour the frozen objects in the barrel onto the workbench of the slicer 2. Use the sliding of the frozen objects on the workbench to rotate the frozen objects and push the frozen objects under the band saw of the slicer 2 for slicing. The band saw cuts along the interfaces between the waste residue layer 402, the waste water layer 404, and the waste oil layer 405 respectively. It should be noted that in order to reduce the difficulty of wastewater treatment, when cutting the waste water layer 404 and the waste oil layer 405, the cutting surface can be biased towards the waste water layer 404 direction to尽可能 reduce the oil content rate in the waste water layer 404. The cut waste residue layer 402 enters the next process for further treatment. As Fig.10 shown, after the waste water layer 404 is put into the thawing pool 501 and thawed, it is discharged into the biological filter through the sewage discharge pipe 504 for sewage treatment. As Figure 7 shown, after the waste oil layer 405 is put into the water bath pool 301 for thawing and low-temperature evaporation dehydration, it is discharged into the storage oil tank through the oil outlet pipe 306 for storage, and is handed over to a third party with waste oil treatment qualifications for further processing.

[0051] It should be noted that the side wall of the storage bucket 101 and the side of the bucket body corresponding to the turning groove 1012 facing the inside of the bucket are both provided with a draft angle to facilitate the separation of frozen objects. Figure 1 and Figure 2 As shown, multiple freezing bins 1 can be used according to the daily amount of food waste, and one or more freezing bins 1 can be selectively used for processing at the same time according to the specific collection amount of the day, which effectively avoids the energy waste caused by the continuous operation of the equipment at full load, while the traditional three-phase centrifuge needs to rotate at high speed to generate strong centrifugal force to achieve the separation of the three phases of slag, water and oil when working. This requires a lot of electricity to drive the motor, and in order to maintain the stable operation of the equipment and a good separation effect, a matching cooling, lubrication and other systems are also required, which further increases energy consumption.

[0052] Through the above technical solution, by adopting the combination of the storage bucket 101 and the refrigeration component 102, the food waste with different daily output can be processed in batches, which can effectively control energy consumption and improve the effect of energy conservation and emission reduction; at the same time, as the first processing step of food waste, the spread of food waste odor is effectively reduced through freezing and screening, and the growth of bacteria is also reduced, thereby improving the hygiene and safety of the entire processing system.

[0053] As a preferred embodiment, the freezing chamber 1 further comprises an ultrasonic component 103 , wherein the ultrasonic component 103 has a plurality of transducers 1032 , and the transducers 1032 abut against the bottom of the storage bucket 101 .

[0054] A groove is also provided at the bottom of the pit. After the shell 1031 is placed in the bottom of the groove and fixed, an ultrasonic generator and a transducer 1032 are placed in the shell 1031, and then a partition 1033 is covered. Under natural conditions, some cystic waste residues, such as bean pod shells, animal viscera, etc., will remain suspended due to bubbles inside or a large amount of waste oil attached to the surface, and it is difficult to stratify and precipitate well. Therefore, after ultrasonic waves are applied to the swill 401, Figure 2 As shown, in the storage barrel 101 at the middle position, the waste residue is fully separated from the gas and sinks to compact each other, while the waste oil attached to the surface of the waste residue is separated from it and fully emulsified with the waste water to float.

[0055] Through the above technical scheme, the cavitation effect generated by ultrasound is used to enhance the separation efficiency of waste residues and waste oil in kitchen waste, and improve the utilization efficiency of waste oil in kitchen waste.

[0056] As a preferred embodiment, the refrigeration component 102 includes a semiconductor refrigeration sheet 1021 and a heat dissipation water pipe 1023. The semiconductor refrigeration sheet 1021 has a cold surface and a hot surface. The cold surface abuts against the outer wall of the storage bucket 101, and the hot surface abuts against the heat dissipation plate 1022. The heat dissipation water pipe 1023 is connected to the side of the heat dissipation plate 1022 facing away from the semiconductor refrigeration sheet 1021.

[0057] When in use, the semiconductor refrigeration sheet 1021 is started, and its cold surface cools the storage barrel 101, and the heat generated by its hot surface is dissipated backward through the heat dissipation plate 1022, and then absorbed by the water flowing in the heat dissipation water pipe 1023. The hot water is transported to the subsequent process through the pipeline for recycling.

[0058] Through the above technical solution, semiconductor refrigeration plate 1021 is used for refrigeration, which improves the refrigeration efficiency, reduces harmful by-products caused by refrigeration, and improves the environmental protection of refrigeration; at the same time, the hot water generated by heat dissipation can be recycled for further utilization, thereby improving the energy utilization efficiency.

[0059] As a preferred implementation method, Figure 5 and Fig.11 As shown, the garbage and sewage water separation device also includes a water bath 301, which is used to hold the waste oil layer 405. The water bath 301 melts the waste oil layer 405 by heating it in a water bath and evaporates the residual water in the waste oil layer 405 at a low temperature. The water bath 301 is connected to the heat dissipation water pipe 1023.

[0060] When using, Figure 7 As shown, the hot water discharged from the heat dissipation water pipe 1023 is pumped into the water bath 301 from the water inlet pipe 303 by a water pump. After the condensation cover 302 is lifted up by the crane connection ring 305, the frozen waste oil layer 405 is thrown into the inner cavity in the middle of the water bath 301. The hot water is isolated outside the inner cavity to heat the inner cavity. After the heat is fully released, the circulating water becomes warm water and is discharged into the next process from the water outlet pipe 304 at the top of the water bath 301.

[0061] It should be noted that the hot water introduced from the lower part of the water bath 301 can maintain a higher temperature in the lower part of the water bath 301, so that the inner cavity can be fully heated, and the water in the waste oil in the inner cavity can evaporate and overflow after being fully heated. The overflowed water vapor condenses on the condensation cover 302 and flows into the water bath 301 to participate in the circulation, so that the water content in the waste oil near the oil outlet pipe 306 can be kept sufficiently low. The oil outlet pipe 306 requires an external valve to drain the oil; the water inlet pipe 303 is connected to the outlet of the heat dissipation water pipe 1023, and the specific setting position of the water bath 301 can be freely arranged according to the spatial layout of the processing workshop.

[0062] Through the above technical solution, the water bath heating evaporation method is adopted to fully utilize the hot water generated by the heat dissipation of the semiconductor refrigeration plate 1021 to heat the waste oil, thereby saving energy; at the same time, it also avoids the deterioration of oil products to a certain extent and reduces the water content of oil products.

[0063] As a preferred implementation method, Figure 8 As shown, the garbage and sewage water separation device also includes a thawing pool 501, which is used to hold the wastewater layer 404. The thawing pool 501 has a plurality of heat pipes, which are connected to the water bath 301. The heat pipes abut against the wastewater layer 404 and melt the wastewater layer 404.

[0064] When using, Fig. 9 As shown, the warm water discharged through the outlet pipe 1 304 enters the heat pipe 1 502 and the heat pipe 2 503 through the inlet pipe 2 5022 and the inlet pipe 3 5031 respectively. After releasing the heat, the warm water becomes cold water and is discharged into the heat dissipation water pipe 1023 through the outlet pipe 2 5021 and the outlet pipe 3 5032.

[0065] It should be noted that the thawing pool 501 is the same as the water bath 301, and only has a specific pipeline connection, while the thawing pool 501 itself is arranged according to the spatial layout of the workshop; the power for circulating water is provided by a multi-stage water pump.

[0066] Through the above technical solution, the frozen wastewater layer 404 is thawed by using warm water discharged from the water bath 301, which shortens the waiting time for wastewater treatment, avoids the use of additional heat sources, and improves energy saving and treatment efficiency.

[0067] As a preferred implementation method, Fig.10 As shown, the heat pipes include heat pipe 1 502 and heat pipe 2 503 . Heat pipe 1 502 is connected to the thawing pool 501 in a V-shape. Heat pipe 2 503 is connected to the thawing pool 501 and is parallel to the bottom surface of the thawing pool 501 .

[0068] Through the above technical solution, a V-shaped heat pipe 1 502 is used to quickly melt the large frozen wastewater layer 404 and decompose it into small pieces of frozen wastewater, which further fall into the bottom of the thawing pool 501. Then, the small pieces of frozen wastewater are fully thawed by the heat pipe 2 503 at the bottom, and the warm water is fully utilized to melt the wastewater layer 404.

[0069] This embodiment also provides a garbage and sewage water separation treatment process, which uses the above-mentioned garbage and sewage water separation device and also includes the following steps:

[0070] Step S1: pouring the swill 401 transferred from the transfer bucket 4 into the storage bucket 101 to stand and separate into layers;

[0071] Step S2: Freeze the layered swill 401 in the storage barrel 101 through the cold surface of the thermoelectric cooler 1021. Use circulating water to cool the hot surface of the thermoelectric cooler 1021 through the heat dissipation water pipe 1023 and generate hot water.

[0072] Step S3: Divide the layered and frozen swill 401 by the slicer 2. The frozen wastewater layer 404 is sent to the thawing pool 501 for thawing and then discharged into the biological filter for biochemical treatment. The frozen waste oil layer 405 is sent to the water bath pool 301. The waste oil layer 405 melts in the water bath pool 301 and undergoes low-temperature evaporation to remove residual moisture. The waste oil after removing moisture is discharged into the storage oil tank for storage.

[0073] Through the above technical solution, by using static layering and freezing, the energy consumption for sorting kitchen waste is reduced. At the same time, due to the low-temperature and solid-state treatment methods for kitchen waste, the environmental pollution in the pretreatment stage is reduced, and the environmental friendliness of the process flow is improved.

[0074] As a preferred implementation manner, in the above step S3, the hot water used in the water bath pool 301 comes from the hot water discharged from the heat dissipation water pipe 1023 in step S2. After the hot water heats and melts the waste oil layer 405 and undergoes low-temperature evaporation in the water bath pool 301, warm water is formed.

[0075] Through the above technical solution, the heat in the entire device is fully utilized through water circulation, improving the energy-saving effect.

[0076] As a preferred implementation manner, in the above step S3, warm water discharged from the water bath pool 301 is introduced into the heat pipe one 502 and the heat pipe two 503 in the thawing pool 501. After passing through the heat pipe one 502 and the heat pipe two 503, the warm water forms cold water, and the cold water circulates back to the heat dissipation water pipe 1023 to continue cooling the hot surface of the thermoelectric cooler 1021.

[0077] Through the above technical solution, the cold water generated by the internal circulation in the thawing pool 501 is used to cool the hot surface of the thermoelectric cooler 1021, further improving the cooling effect.

[0078] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded in the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.

The garbage and sewage water separation treatment process according to claim 7 is characterized in that: In step S3, the hot water used in the water bath comes from the hot water discharged from the heat dissipation water pipe (1023) in step S2. The hot water is heated and melted in the water bath (301) and evaporated at low temperature to form warm water.

9. The garbage and sewage water separation treatment process according to claim 8 is characterized in that: In step S3, warm water discharged from the water bath (301) is introduced into heat pipe one (502) and heat pipe two (503) in the thawing pool (501). The warm water passes through heat pipe one (502) and heat pipe two (503) to form cold water. The cold water circulates back to the heat dissipation water pipe (1023) to continue cooling the hot surface of the semiconductor refrigeration plate (1021).
