Description

Technical Field

[0001] This application relates to the field of food waste treatment technology, specifically a food waste processor. Background Technology

[0002] Kitchen waste refers to various types of waste generated when people engage in activities related to daily eating. Common kitchen waste includes leftover food, vegetable scraps, fruit peels, and various bones. It is mainly generated in family kitchens, restaurants, and other food processing industries.

[0003] Kitchen waste contains a large number of harmful bacteria, which are highly contagious and pathogenic, threatening people's health. From an ecological perspective, kitchen waste contains a large number of microorganisms and organic matter, making it prone to rotting and emitting unpleasant odors, causing air pollution. In China, most kitchen waste is treated as solid waste through physical, chemical, and biological methods, such as incineration, landfill, and composting. These methods generate a large number of harmful substances, causing water, air, and soil pollution, which harm the environment to varying degrees. Another portion of the kitchen waste generated by households will be discharged into the urban sewage system through the sewer system. This waste contains a large amount of organic matter, which will not only exacerbate the blockage of urban pipes but also corrode them, increasing maintenance costs. A large amount of organic matter will also be wasted.

[0004] Therefore, this application provides a food waste disposer to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a food waste disposer, which aims to solve the problem mentioned in the background art that another part of the food waste generated by households is discharged into the urban sewage system through the sewer pipes. This waste contains a large amount of organic matter, which not only aggravates the blockage of urban pipes, but also corrodes urban pipes, increases maintenance costs, and a large amount of organic matter is wasted.

[0006] To achieve the above objectives, this application provides the following technical solution: a kitchen waste disposer, comprising an assembly rack and a first shelf and a second shelf equidistantly mounted on the assembly rack, wherein a solid-liquid separation component is mounted on the first shelf;

[0007] The solid-liquid separation assembly includes a solid-liquid separator mounted on the first shelf. A cover plate is detachably mounted on the upper end of the solid-liquid separator, and a feed inlet is located on the upper end of the cover plate. A circular tube is mounted on the side of the solid-liquid separator, and a first servo motor is mounted on the end of the circular tube furthest from the solid-liquid separator. A screw propeller is mounted on the output end of the first servo motor. A filter screen fitted to the inner wall is installed inside the solid-liquid separator, and a crushing assembly is located at the lower end of the circular tube. The barrel also functions as a filter medium. By first separating the solid and liquid components of kitchen waste, the solid waste is sequentially fed into the crushing assembly for processing and crushing, facilitating recycling.

[0008] Preferably, the screw propeller includes a screw shaft fixedly installed at the output end of the first servo motor, one end of the screw shaft is rotatably connected to the solid-liquid separator, and screw blades are installed on the outside of the screw shaft.

[0009] Preferably, the pulverizing assembly includes a pulverizing seat installed at the lower end of the circular tube, a second servo motor installed at the lower end of the pulverizing seat, the second servo motor being installed on a second frame, a cutter disc connected to the output end of the second servo motor being provided inside the pulverizing seat, a discharge port being fixedly installed at one end of the pulverizing seat, and a cutter disc with multiple multi-directional pulverizing functions being installed in the pulverizing chamber, which is the place for pulverizing food waste.

[0010] Preferably, an oil-water separation component connected to the solid-liquid separator is provided at the end of the second shelf away from the second servo motor.

[0011] Preferably, the oil-water separation assembly includes an oil-water separation tank installed on the upper end of the second shelf. The oil-water separation tank is connected to the lower end of the solid-liquid separator via a sludge guide pipe. A third servo motor is installed on the side of the oil-water separation tank. A separation chamber plate is installed inside the oil-water separation tank. An oil scraper is rotatably connected to the end of the oil-water separation tank away from the sludge guide pipe. The output end of the third servo motor is connected to the shaft end of the oil scraper. After the oil and water are injected, the heating wire is energized to accelerate the separation of oil and water, and finally the mixed liquid is separated into an upper layer of oil and a lower layer of water.

[0012] Preferably, the upper and lower sealing plates of the oil-water separator are provided with accommodating cavities, heating wires are installed in the accommodating cavities, liquid guide pipes are provided inside the oil-water separator, and drain pipes are installed on the oil-water separator.

[0013] Preferably, an oil tank is fixedly installed at the end of the oil-water separator away from the drain pipe, and an oil guide port for the oil scraper to drain oil is opened at the upper end of the oil tank, and an oil drain valve is provided at one end of the oil tank.

[0014] This food waste disposer pours food waste into the solid-liquid separator through the feed inlet. The upper spiral blades of the rotating shaft propel the waste, using centrifugal force to remove oil and water. At the same time, the shortened screw pitch squeezes the solid waste to remove water, thereby achieving solid-liquid separation and facilitating further processing of the separated solid and liquid waste.

[0015] This food waste disposer, after screening, allows the oil-water mixture to enter the oil-water separation tank through the drain pipe. Electricity is applied to the heating wire to accelerate the separation of oil and water. The mixture eventually separates into an upper layer of oil and a lower layer of water. Water is injected through the drain pipe to control the oil level. When the oil level approaches the scraper, a third servo motor drives the scraper to rotate, scraping the separated floating oil into the oil tank, thus achieving the collection and utilization of oil and water.

[0016] This food waste disposer works by sending solid waste into the grinding chamber through the grinding plate, where it is ground by the blades and then discharged for centralized collection and reuse. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This embodiment provides a food waste disposer, such as Figure 1-4 As shown, the food waste disposer includes an assembly rack 1 and a first shelf 11 and a second shelf 12 equidistantly mounted on the assembly rack 1. A solid-liquid separation component is installed on the first shelf 11.

[0025] The solid-liquid separation assembly includes a solid-liquid separator 2 installed on the first shelf 11. A cover plate 21 is detachably installed on the upper end of the solid-liquid separator 2. A feed inlet 22 is provided on the upper end of the cover plate 21. A circular tube is installed on the side of the solid-liquid separator 2. A first servo motor 23 is installed at the end of the circular tube away from the solid-liquid separator 2. A screw propeller 25 is installed at the output end of the first servo motor 23. A filter screen 24 that fits the inner wall is installed inside the solid-liquid separator 2. A crushing assembly is provided at the lower end of the circular tube.

[0026] For details, please refer to the appendix. Figure 3 The screw propeller 25 is installed in the structural diagram of the solid-liquid separator 2. It has many similarities with the composition of an extruder. In order to achieve the goal of crushing, compacting and dehydrating the material, the diameter of the large end of the central shaft is designed to be much larger than that of the small end to increase the taper, and the blade spacing in the direction of travel is gradually shortened, making it more sensitive to the moisture content in the material. The structure of the barrel is also modified. Without affecting the material travel, holes are directly opened on the shell wall or grooves are opened at the bottom of the barrel to place the filter screen 24, so that the barrel also serves as a filter medium. By first separating the solid and liquid of the kitchen waste, the solid waste is sent to the crushing component for processing and crushing, which is convenient for recycling. At the same time, the oily wastewater is sent to the predetermined position for oil-water separation, reducing pollution during processing.

[0027] The screw propeller 25 includes a screw shaft fixedly installed at the output end of the first servo motor 23. One end of the screw shaft is rotatably connected to the solid-liquid separator 2, and screw blades are installed on the outside of the screw shaft.

[0028] More specifically, the screw propeller 25 of this solution can be equipped with a heating element on the outer wall of the barrel in the interval between the compression section and the extrusion section to increase the seepage rate of the liquid phase. In terms of the setting of equipment operating parameters, the speed is usually set to 30-140 rpm to increase the crushing and pressing time of the material and make the equipment run more smoothly.

[0029] The crushing assembly includes a crushing seat 3 installed at the lower end of a circular tube. A second servo motor 33 is installed at the lower end of the crushing seat 3. The second servo motor 33 is installed on the second frame layer 12. The crushing seat 3 has a cutter disc 32 connected to the output end of the second servo motor 33 inside. A discharge port 31 is fixedly installed at one end of the crushing seat 3.

[0030] Furthermore, when the cutter disc 32 inside the shredder 3 rotates at high speed, the solid waste being processed will not rotate synchronously with the cutter disc 32, thus creating a speed difference. Combined with the centrifugal force acting on the processed material, the movement of the processed material and the cutter disc 32 is also in opposite directions. In this way, relying on the internal toothed ring, the end toothed ring, and the high-speed rotating blades to crush and tear the processed material, the food waste is quickly turned into 3-5mm particles. The shredder 3 consists of four parts: the inlet, the cutter disc 32, the shredding chamber, and the discharge port 31. The second servo motor 33 provides the power source for the processor. The shredding chamber is equipped with a multi-directional shredding cutter disc 32, which is the place where food waste is shredded. The second servo motor 33 and the cutter disc 32 are key parts of the waste processor, directly affecting the performance of the waste processor. This machine is more suitable for my country's food structure and housing characteristics. The shredding component will receive the waste that has been processed by the dehydration module, and the waste is shredded and discharged through the above process.

[0031] The second shelf 12, at the end furthest from the second servo motor 33, is equipped with an oil-water separation component connected to the solid-liquid separator 2.

[0032] Among them, the solid-liquid separator 2 is connected to the oil-water separation component, which can separate oil and water in the oily wastewater that causes pollution, thereby reducing pollution.

[0033] The oil-water separation assembly includes an oil-water separation tank 4 installed on the upper end of the second shelf 12. The oil-water separation tank 4 is connected to the lower end of the solid-liquid separator 2 through a sludge guide pipe 5. A third servo motor 42 is installed on the side of the oil-water separation tank 4. A separation chamber plate 45 is installed inside the oil-water separation tank 4. An oil scraper 421 is rotatably connected to the end of the oil-water separation tank 4 away from the sludge guide pipe 5. The output end of the third servo motor 42 is connected to the shaft end of the oil scraper 421.

[0034] Furthermore, after the oil and water are injected, the heating wire 44 is energized to accelerate the separation of oil and water. The final mixed liquid is divided into an upper layer of oil and a lower layer of water. Water is injected through the liquid guide pipe 47 to control the oil level. When the oil level is close to the oil scraper 421, the third servo motor 42 drives the oil scraper 421 to rotate, scraping the separated floating oil to the oil tank 46. The separation chamber plate 45 divides the chamber, prolonging the liquid residence time and improving the separation effect, thereby realizing the collection and utilization of oil and water. The surface roughening treatment of the oil scraper 421 enhances the adhesion to oil.

[0035] The upper and lower sealing plates of the oil-water separator 4 are provided with accommodating cavities. A heating wire 44 is installed in the accommodating cavity. A liquid guide pipe 47 is provided inside the oil-water separator 4. A drain pipe 43 is installed on the oil-water separator 4.

[0036] It should be noted that by opening cavities in the upper and lower sealing plates to install heating wires 44, the oil-water separation is accelerated, while preventing grease from solidifying and clogging the pipes.

[0037] An oil tank 46 is fixedly installed at the end of the oil-water separator 4 away from the drain pipe 43. An oil guide port for the oil scraper 421 to drain oil is opened at the upper end of the oil tank 46, and an oil drain valve 41 is provided at one end of the oil tank 46.

[0038] It is worth mentioning that the oil scraper 421 scrapes the floating oil into the oil tank 46 for temporary storage. When the oil level in the oil tank 46 reaches the set value, the oil drain valve 41 is opened to discharge the oil for resource utilization such as biodiesel.

[0039] In use, firstly, kitchen waste is poured into the solid-liquid separator 2 through the feed inlet 22. The waste is propelled by the upper spiral blades of the rotating shaft, and the oil and water are separated by centrifugal force. At the same time, the screw pitch is shortened to squeeze the solid waste and dehydrate it. The oil-water mixture after screening enters the oil-water separation tank 4 through the guide pipe 5. The heating wire 44 is energized to accelerate the separation of oil and water. Finally, the mixture is separated into an upper layer of oil and a lower layer of water. Water is injected through the liquid guide pipe 47 to control the oil level. When the oil level is close to the oil scraper 421, the third servo motor 42 drives the oil scraper 421 to rotate, scraping the separated floating oil to the oil tank 46. The other part of the solid waste enters the crushing chamber through the crushing seat 3, is crushed by the cutter disc 32, and is finally discharged.

[0040] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
