Description

Technical Field

[0001] The present invention relates to the technical field of resource recycling, and in particular to a device for processing kitchen waste. Background Art

[0002] When recycling solid waste such as kitchen waste (i.e., kitchen waste), the perishable organic waste generated by kitchen waste has certain recycling value, such as being used to produce fertilizers or fuel, and the oil and fat in it can also be used to produce some industrial raw materials. The kitchen solid waste treatment device can recycle it through operations such as crushing, drying and separation, which is beneficial to resource utilization and environmental protection.

[0003] In the prior art, Chinese patent application number CN201810588648.3 discloses a food waste treatment system comprising: a preliminary separation device for receiving food waste and preliminarily separating the food waste into leachate, solid waste, and wet material; a wet material treatment device for receiving the wet material and performing a squeezing and dehydration process on the wet material to obtain a wet material liquid phase and a wet material solid phase; a liquid phase treatment device for receiving the leachate and the wet material liquid phase and further separating the mixture of the leachate and wet material liquid phase into oil, organic matter, and liquid impurities; and a material fermentation device for receiving the wet material solid phase and organic matter, mixing the wet material solid phase and organic matter with auxiliary materials to form a fermentation feedstock, and fermenting the fermentation feedstock into a bio-fermentation product. This system can quickly and efficiently treat food waste, addressing the problem of secondary environmental pollution caused by prior art food waste treatment.

[0004] For example, in the prior art, Chinese patent application number CN201811283456.8 discloses a kitchen waste treatment device, which includes a crusher, an extrusion dehydration and conveying system, and a biochemical reaction chamber. The crusher is used to crush the material to be processed, the extrusion dehydration and conveying system is used to extrude and dehydrate the crushed material and output the dehydrated material. The biochemical reaction chamber contains microorganisms, which are used to perform microbial treatment on the material output by the extrusion dehydration and conveying system. A stirring device and a heating device are provided in the biochemical reaction chamber, and the biochemical reaction chamber is also connected to an exhaust fan. By adding high-temperature aerobic microorganisms into the biochemical reaction chamber, and maintaining the high temperature and sufficient oxygen in the biochemical reaction chamber by the heating device and the exhaust fan, the material and the microorganisms are fully contacted by the stirring device.

[0005] For another example, Chinese patent application number CN202110670497.8 discloses a food waste treatment device and method. The device includes a frame, a pulverizing mechanism, a compression mechanism, and a packaging mechanism. The pulverizing mechanism is fixedly mounted on the top of the frame, the compression mechanism is fixedly mounted within the inner cavity of the frame, and the packaging mechanism is located on the right side of the frame. The packaging mechanism includes a support cylinder located to the right of the compression mechanism. The packaging mechanism can package the compressed solid food waste. During packaging, the support cylinder supports the packaging bag. Food waste discharged from the compression mechanism gradually enters the packaging bag. As the food waste enters, the packaging bag gradually expands. When the packaging bag expands to its limit, it can be removed and replaced.

[0006] Based on the above materials, it can be seen that the existing technology generally processes solid kitchen waste by crushing and fermenting it. However, in actual use, kitchen waste is generally mainly food residues, which contain a large amount of oil. Oil has a certain recycling value (such as producing some industrial raw materials, etc.), but the existing technology does not recycle oil, resulting in waste. Summary of the Invention

At the same time, a first spring is provided on the outside of the upper end of the connecting rod, and the connecting rod is used to enable the collecting bucket to drive the filling block to move synchronously.

[0010] Preferably, an oil drain pipe connected to the right upper end of the separation box is fixedly installed, and a water drain pipe connected to the left lower end of the separation box is fixedly installed, and the upper layer of grease can be discharged and recycled by means of the oil drain pipe.

[0011] Preferably, the dosing mechanism includes a connecting pipe fixedly installed between the first block and the second block, and a discharge pipe fixedly installed on the side of the first block, and a one-way valve is provided on the outside of the connecting pipe and the discharge pipe.

[0012] Preferably, a transversely arranged piston plate is installed inside the first block, and the piston plate slides in contact with the inner wall of the first block and is always located below the discharge pipe. The demulsifier inside the first block can be discharged through the discharge pipe by squeezing the piston plate.

[0013] Preferably, a second spring is fixedly installed between the lower surface of the piston plate and the inner wall of the first block, and an extrusion block is fixedly installed in the middle position of the lower surface of the piston plate, and the extrusion block slides through the lower surface of the first block.

[0014] Preferably, the negative pressure head is communicated with the purification box through a connecting pipe connected thereto, and deodorizing activated carbon is fixedly installed inside the purification box, and the deodorizing activated carbon is used to absorb odors to achieve the purpose of deodorization.

[0015] Preferably, an air delivery pump docked with the connecting pipe is fixedly installed on the upper surface of the purification box, a diverter pipe is installed in the middle of the connecting pipe, and a one-way control valve is provided at the connection position between the diverter pipe and the connecting pipe.

[0016] Preferably, the top end of the diversion pipe extends to the inside of the collecting hopper, and an electric heater for drying garbage is fixedly installed on the inner wall of the collecting hopper.

[0017] Preferably, a heat exchange tube is fixedly installed through the lower end of the purification box, and the front end of the heat exchange tube is a bent structure, and the bent structure of the heat exchange tube is located inside the separation box.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the device for processing kitchen waste adopts a new structural design, the specific contents of which are as follows: 1. Kitchen waste is poured onto a conveyor belt for transportation. At this time, some non-recyclable garbage such as plastic bags are manually sorted out. The waste then enters the processing box through a chute, is crushed by the crushing roller in the processing box and falls into the collection hopper. At this time, the drain plate is used to separate the solid and liquid. The solid remains in the collection hopper, and the liquid passes through the drain plate and falls into the separation box, ultimately achieving the purpose of solid waste treatment and recycling; 2. The liquid entering the separation box is separated into layers (oil in the upper layer, water in the lower layer) by utilizing the density difference between water and grease. As the overall weight of the collection hopper increases, the first spring is compressed. At this time, the connecting rod drives the filling block to move downward inside the separation box, thereby increasing the liquid level by allowing the filling block to enter the liquid, allowing the upper layer of grease to be discharged smoothly through the oil drain pipe, and the lower layer of water to be discharged through the drain pipe. Furthermore, when the first block moves downward, the extrusion block below it is squeezed against the inner wall of the separation box. At this time, the extrusion block is used to drive the piston plate to move upward, thereby discharging the demulsifier inside the first block through the discharge pipe (the one-way valve outside the discharge pipe allows it to only be discharged). The demulsifier is used to change the properties of the oil and fat, thereby improving the oil-water separation effect. When the piston plate is reset, the negative pressure is used to suck the demulsifier in the second block into the first block through the connecting pipe (the one-way valve outside the connecting pipe allows the demulsifier to only flow from the second block into the first block).

[0019] 3. When manually sorting plastic waste, turn on the air pump and use the connecting pipe to create negative pressure at the negative pressure head position, thereby inhaling the surrounding air to reduce the spread of odor from kitchen waste. The inhaled air enters the purification box, and the deodorizing activated carbon in the purification box removes the odor; Furthermore, under the action of the delivery air pump, the air in the treatment box is drawn into the purification box through the diversion pipe (an electric heater is provided in the treatment box, and the electric heater is used to heat the air to achieve the purpose of drying), so that the purified gas enters the heat exchange tube with a certain amount of heat, and the heat exchange tube is used to heat the liquid in the separation box, and the heating makes it easier for the grease to gather and form oil-water separation.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-Figure 5 In order to achieve the purpose of reducing the impact of odor during manual sorting, this embodiment provides the following technical solutions, which specifically disclose: a horizontally arranged conveying platform 1, a supporting leg 2 and a processing box 3 are fixedly installed below the conveying platform 1, a conveyor belt 4 is rotatably installed on the upper left side of the conveying platform 1, a guide baffle 5 fixedly installed with the conveying platform 1 is provided on the right side of the conveyor belt 4, and a material drop chute 6 is provided at the upper end of the processing box 3; a crushing roller 7 is rotatably installed at the upper end of the processing box 3, and a collecting bucket 8 is installed at the lower end of the processing box 3, negative pressure heads 22 are fixedly installed on the front and rear sides of the conveying platform 1, and a purification box 23 is fixedly installed on the left side of the processing box 3, the negative pressure head 22 is connected to the purification box 23 through a connecting pipe 24 connected thereto, and deodorizing activated carbon 2301 is fixedly installed inside the purification box 23, and a conveying air pump 25 connected to the connecting pipe 24 is fixedly installed on the upper surface of the purification box 23.

[0024] When using the device, the kitchen waste (i.e., kitchen waste) is first poured onto the conveyor belt 4 (the length of the conveyor belt 4 can be adjusted according to actual usage and extended by splicing the conveying platform 1). Then, the conveyor belt 4 is rotated by the motor to convey the waste from left to right. During this process, the staff on the front and rear sides of the conveying platform 1 manually select the non-recyclable garbage (such as plastic bags, etc.). During this process, the conveying air pump 25 is turned on. Under the action of the conveying air pump 25 and the connecting pipe 24, a negative pressure is formed at the position of the negative pressure head 22. The negative pressure is used to suck the air around the conveying platform 1 into the purification box 23. The deodorizing activated carbon 2301 in the purification box 23 removes odors, reducing the odor around the conveying platform 1 from affecting the work of the staff. Finally, the waste falls into the processing box 3 through the drop chute 6. At this time, the motor at the rear of the processing box 3 drives the crushing roller 7 to rotate. The crushing roller 7 breaks the waste into small pieces and drops it into the collection bucket 8 for collection. Finally, the staff takes out the waste from the collection bucket 8 for recycling.

[0025] Example 2: Please refer to Figures 6-11 In order to achieve the purpose of oil-water separation and grease recovery, this embodiment provides the following technical solutions, which specifically disclose: a corresponding separation box 9 is fixedly installed under the collecting bucket 8, and the conveyed collecting bucket 8 is connected to the separation box 9 through the drain plate 10 on its bottom surface. A filling block 13 for raising the water level is provided inside the separation box 9, and the filling block 13 is divided into a first block 1301 and a second block 1302. A dosing mechanism is provided inside the first block 1301. A connecting rod 14 is fixedly installed on the upper surface of the filling block 13, and a through-type sliding structure is formed between the connecting rod 14 and the separation box 9, and the top end of the connecting rod 14 is fixedly installed on the lower surface of the collecting bucket 8. At the same time, a first spring 15 is provided on the outside of the upper end of the connecting rod 14, and the upper right end of the separation box 9 is fixedly installed and connected to it. The oil drain pipe 11 is fixedly installed at the lower left end of the separation box 9 and is connected to the drain pipe 12. The dosing mechanism includes a connecting pipe 16 fixedly installed between the first block 1301 and the second block 1302, and a discharge pipe 17 is fixedly installed on the side of the first block 1301, and a one-way valve is provided on the outside of the connecting pipe 16 and the discharge pipe 17. A transversely arranged piston plate 18 is installed inside the first block 1301, and the piston plate 18 slides in contact with the inner wall of the first block 1301, and the piston plate 18 is always located below the discharge pipe 17. A second spring 20 is fixedly installed between the lower surface of the piston plate 18 and the inner wall of the first block 1301, and an extrusion block 19 is fixedly installed in the middle position of the lower surface of the piston plate 18, and the extrusion block 19 slides through the lower surface of the first block 1301.

[0026] After the waste falls onto the collecting hopper 8, the drain plate 10 is used to separate the solid and liquid of the waste. At this time, the solid remains inside the collecting hopper 8, while the liquid passes through the drain plate 10 and falls into the separation box 9 below. The different densities of oil and water in the liquid are used to form layers (grease is in the upper layer and water is in the lower layer). As the weight of the waste in the collecting hopper 8 increases, the weight also increases. At this time, under the action of gravity, the collecting hopper 8 compresses the first spring 15, so that under the push of the connecting rod 14, the filling block 13 moves downward in the separation box 9, so that more volume of the filling block 13 enters the liquid. Under the filling action of the filling block 13, the liquid level in the separation box 9 rises. At this time, the oil drain pipe 11 is used to discharge the upper layer of grease, and the drain pipe 12 is used to discharge the lower layer of water. In the process of the filling block 13 moving downward The extrusion block 19 below the first block 1301 is squeezed against the inner wall of the separation box 9. Under the action of the extrusion force, the piston plate 18 above the extrusion block 19 moves upward relative to the first block 1301. Under the extrusion of the piston plate 18, the demulsifier at the upper end of the first block 1301 is discharged through the discharge pipe 17, and the demulsifier is used to improve the oil-water separation effect in the separation box 9. After that, when the staff takes out the waste in the collection bucket 8, the collection bucket 8 is reset upward under the action of the first spring 15, and at the same time, the piston plate 18 is reset downward under the action of the second spring 20. At this time, under the action of negative pressure, the demulsifier stored in the second block 1302 is sucked into the first block 1301 through the connecting pipe 16 to ensure the retention of demulsifier in the first block 1301.

[0027] Example 3: Please refer to Figure 4 and Figure 7 In order to achieve the purpose of improving the oil-water separation effect, this embodiment provides the following technical solutions, which specifically disclose: a diverter pipe 26 is installed in the middle position of the connecting pipe 24, and a one-way control valve 27 is provided at the connection position between the diverter pipe 26 and the connecting pipe 24. The top end of the diverter pipe 26 extends into the inside of the collecting bucket 8, and an electric heater 21 for drying garbage is fixedly installed on the inner wall of the collecting bucket 8. A heat exchange pipe 28 is fixedly installed through the lower end of the purification box 23, and the front end of the heat exchange pipe 28 has a bent structure, and the bent structure of the heat exchange pipe 28 is located inside the separation box 9.

[0028] During the waste treatment process, the electric heater 21 inside the collection bucket 8 is turned on, and the electric heater 21 is used to generate heat to dry the waste, reducing the moisture content to facilitate subsequent recycling. At the same time, under the action of the delivery air pump 25, the gas in the collection bucket 8 enters the connecting pipe 24 through the diverter pipe 26 (the one-way control valve 27 at the connection position of the diverter pipe 26 and the connecting pipe 24 allows the gas to enter the connecting pipe 24 only through the diverter pipe 26), so that the gas purified by the deodorizing activated carbon 2301 has a certain amount of heat and is discharged from the heat exchange pipe 28. The heat exchange pipe 28 is used to heat the liquid in the separation box 9 to achieve a better oil-water separation effect.

[0029] This device can be used in the garbage disposal of large-scale catering shopping malls (for the disposal of solid waste in the back kitchen), and can also be used in the treatment of kitchen waste in garbage disposal stations, that is, it can be used in any kitchen waste treatment site that reaches a certain scale.
