Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste treatment devices, specifically a high-efficiency solid-liquid separation device for kitchen waste that is easy to disassemble and clean. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards, the amount of food waste generated is increasing daily. Statistics show that my country generates tens of millions of tons of food waste annually. If this waste is not properly disposed of, it will not only occupy a large amount of land resources but also easily breed bacteria, produce odors, and cause serious environmental pollution. Solid-liquid separation is a key step in food waste treatment; efficient solid-liquid separation can lay a solid foundation for subsequent waste treatment and resource recycling.

[0003] For example, the patent with national authorized patent announcement number CN215939200U discloses a solid-liquid separation device for food waste treatment, including a box body. A solid-liquid separation cylinder is inclinedly arranged inside the box body, which reduces the height of the equipment, facilitates manual operation, extends the conveying distance, and allows for more sufficient dehydration time, thus helping to reduce the water content of food waste. The solid-liquid separation cylinder has a feeding channel at the lower end and a discharge channel at the upper end. Several water outlet holes are arranged on the solid-liquid separation cylinder. A rotating shaft and a spiral blade are coaxially installed inside the solid-liquid separation cylinder. The inclined rotating shaft and spiral blade can prevent food waste from rotating with the spiral blade, avoiding blockage and leaving no residue. A detachable mechanism is provided between the upper end of the rotating shaft and the box body. A motor device that is detachably connected to the rotating shaft is provided on one side of the box body, which is convenient for disassembly and assembly, easy for cleaning and maintenance, and improves maintenance efficiency.

[0004] However, the aforementioned solid-liquid separation device for food waste treatment cannot break down the food waste to fully filter out the water during the solid-liquid separation process. Furthermore, the filter device cannot be easily disassembled and cleaned after use. As dirt accumulates on the filter device, the filter holes will gradually become clogged, resulting in a significant decrease in filtration efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency solid-liquid separation device for kitchen waste that is easy to disassemble and clean, in order to solve the problems mentioned in the background art that the kitchen waste cannot be crushed to fully filter out the water during the solid-liquid separation process, and that the water filter device cannot be easily disassembled and cleaned after use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency solid-liquid separation device for kitchen waste that is easy to disassemble and clean includes: a connecting cylinder, in which two sets of first screws are rotatably installed, and gears are fixedly installed on the outer surfaces of the two sets of first screws, and the two sets of gears mesh with each other, so that the two sets of first screws can be driven to rotate in opposite directions. One set of first screws is fixedly connected to the output shaft of a reduction motor, and the reduction motor is fixedly installed at one end of the connecting cylinder. A sliding groove is opened at one end of the connecting cylinder, and a water filtering mechanism is slidably installed in the sliding groove. A kitchen waste dumping hopper is connected to the upper surface of the connecting cylinder.

[0008] Preferably, the other ends of the two sets of first screws are sequentially fixedly equipped with a first helical shearing blade, a second screw, a second helical shearing blade, and a third screw.

[0009] Preferably, the two sets of first screws, first helical shear blades, second screws, second helical shear blades and third screws are all in a relatively rotating, interlocking manner, and the helical blade distance between the first screw, second screw and third screw gradually decreases.

[0010] Preferably, the water filtration mechanism includes a water filter cylinder, which is slidably installed in a trough. A top pressure block is fixedly installed on the upper surface of the water filter cylinder. The top pressure block slides out of the trough and slides inside an n-shaped cylinder. The n-shaped cylinder is detached and installed on the upper surface of a connecting cylinder by a butterfly bolt. The n-shaped cylinder is connected to the trough.

[0011] Preferably, a sliding column is fixedly installed inside the n-shaped cylinder. The sliding column slides through the top pressure block and is fitted with a spring on its outer surface. One end of the spring is fixedly connected to one end inside the n-shaped cylinder, and the other end touches one end of the top pressure block.

[0012] Preferably, the lower end of the outer surface of the filter cylinder has a filter hole, and a sealing cap is slidably installed at one end of the filter cylinder so that the sealing cap can seal the end of the filter cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the connecting cylinder, reduction motor, n-shaped cylinder, gear, first screw, second screw and third screw, chute and water filtration mechanism, when separating solid and liquid food waste, the reduction motor can be started to drive one set of first screws to rotate. The rotation of the first screw will be driven by the gear fixedly installed on the outer surface of the other set of first screws to rotate through the meshing of the gear fixedly installed on the outer surface. In this way, the two sets of first screws can be driven to rotate in relative meshing. In turn, the two sets of first screws can drive the first spiral shear blade, second screw, second spiral shear blade and third screw fixedly installed at the other end to rotate in relative meshing.

[0015] Subsequently, workers can pour kitchen waste from the kitchen waste dumping hopper into the connecting cylinder. It is first pushed by two sets of first screws, and the kitchen waste pushed by the first screws enters the first spiral shear blades for further chopping. Simultaneously, it is also pushed into the second screw, where the initially chopped kitchen waste is pushed again into the second spiral shear blades for secondary chopping. The secondary-chopped kitchen waste is then pushed into the third screw by the spiral pushing force of the second spiral shear blades. During this pushing process, the gradually decreasing spiral blade distance between the first, second, and third screws (150mm → 100mm → 50mm) creates a gradient compression space, ensuring the kitchen waste is compressed during the pushing process. During the process, the pressure gradually increases from 1.2MPa to 3.5MPa, causing the water to be squeezed out layer by layer. This allows the third screw to push the secondary shredded kitchen waste back into the water filtration mechanism. The water filtration mechanism can slide out of the chute by a corresponding length according to the volume of the kitchen waste to increase its storage capacity. As the water filtration mechanism is pushed out of the chute by the kitchen waste, a restoring spring force is applied, which allows the water filtration mechanism to squeeze the shredded kitchen waste inside through the restoring spring force. This achieves the pressure filtration of the liquid in the kitchen waste. After the water in the kitchen waste is pressure filtered out, the water filtration mechanism can be opened to allow the third screw to push the pressure-filtered kitchen waste out of the water filtration mechanism.

[0016] After multiple filtration cycles, the butterfly bolts securing the n-shaped cylinder can be disassembled by the staff, allowing the filtration mechanism to be pulled out of the trough for cleaning. This effectively prevents the filtration mechanism from being affected by dirt accumulation, thus extending its filtration efficiency and service life.

[0017] 2. Through the design of the filter cylinder, filter holes, sealing cover, top pressure block, and spring, the secondary shredded kitchen waste is pushed into the third screw, which then pushes the secondary shredded kitchen waste into the filter cylinder. The filter cylinder can slide out of the chute a corresponding length according to the volume of the kitchen waste to increase its storage capacity. As the filter cylinder is pushed out of the chute by the kitchen waste, it also drives the top pressure block, which is fixedly installed on the upper surface, to slide on the outer surface of the slide column inside the N-shaped cylinder. This allows the top pressure block to press against one end of the spring fitted on the outer surface of the slide column, and the spring applies a restoring spring force to the top pressure block, pushing the filter cylinder back into the chute. This restoring spring force then compresses the shredded food waste inside the filter cylinder. The process of filtering kitchen waste allows for the extraction of liquids through pressure. The filtered water then drains through filtration holes at the lower end of the outer surface of the filter cylinder. After the water is removed, the sealing cap can be pulled out, allowing the third screw to push the filtered kitchen waste out of the filter cylinder. After multiple filtrations, the butterfly bolts securing the N-shaped cylinder can be removed, allowing the operator to pull the N-shaped cylinder and pull the internal sliding column out of the top pressure block of the filter cylinder. This releases the positional constraint on the filter cylinder, enabling the operator to pull it out of the sliding groove for cleaning. This reduces the residue of dirt and impurities on the filtration holes, lowers the risk of bacterial growth, extends the service life of the filter cylinder, and improves the overall maintenance efficiency of the equipment.

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

[0024] like Figures 1-3 As shown, this embodiment provides a high-efficiency solid-liquid separation device for kitchen waste that is easy to disassemble and clean. It includes: a connecting cylinder 1, two sets of first screws 104 are rotatably installed inside the connecting cylinder 1, and gears 105 are fixedly installed on the outer surfaces of the two sets of first screws 104. The two sets of gears 105 mesh with each other, so that the two sets of first screws 104 can be driven to rotate in opposite directions. One set of first screws 104 is fixedly connected to the output shaft of a reduction motor 102. The reduction motor 102 is fixedly installed at one end of the connecting cylinder 1. A sliding groove 109 is opened at one end of the connecting cylinder 1. A water filtering mechanism 2 is slidably installed in the sliding groove 109. A kitchen waste dumping hopper 101 is connected to the upper surface of the connecting cylinder 1.

[0025] The other ends of the two sets of first screws 104 are sequentially fixed with a first spiral shearing blade 106, a second screw 107, a second spiral shearing blade 110, and a third screw 108. The two sets of first screws 104, first spiral shearing blades 106, second screws 107, second spiral shearing blades 110, and third screws 108 are all in a relatively rotating, interlocking manner, and the spiral blade distance between the first screws 104, second screws 107, and third screws 108 gradually decreases.

[0026] Through the design of the connecting cylinder 1, the reduction motor 102, the n-shaped cylinder 103, the gear 105, the first screw 104, the second screw 107 and the third screw 108, the chute 109 and the water filtration mechanism 2, when separating solid and liquid waste, the reduction motor 102 can be started to drive one set of first screws 104 to rotate. The rotation of the first screw 104 will be driven by the gear 105 fixedly installed on its outer surface to mesh and drive the gear 105 fixedly installed on the outer surface of the other set of first screws 104 to rotate. In this way, the two sets of first screws 104 can be driven to rotate in a relatively meshing manner, and the two sets of first screws 104 can drive the first spiral shear blade 106, the second screw 107, the second spiral shear blade 110 and the third screw 108 fixedly installed at the other end to rotate in a relatively meshing manner.

[0027] Subsequently, workers can pour kitchen waste from the kitchen waste dumping hopper 101 into the connecting cylinder 1. The waste is first pushed by two sets of first screws 104, and then into the first spiral shear blades 106 where it is shredded. Simultaneously, it is pushed into the second screw 107, where the second screw 107 pushes the initially shredded waste again into the second spiral shear blades 110 for secondary shredding. The shredded waste is then pushed into the third screw 108 by the spiral pushing force of the second spiral shear blades 110. During this pushing process, the gradually decreasing spiral blade spacing between the first screw 104, second screw 107, and third screw 108 (150mm → 100mm → 50mm) creates a gradient compression space. During the feeding process, the pressure on the kitchen waste gradually increases from 1.2MPa to 3.5MPa, causing the water to be squeezed out layer by layer. This allows the third screw 108 to push the secondary shredded kitchen waste back into the water filtration mechanism 2. The water filtration mechanism 2 can slide out of the chute 109 by a corresponding length according to the volume of the kitchen waste to increase its storage capacity. As the water filtration mechanism 2 is pushed out of the chute 109 by the kitchen waste, a reset spring force is applied to it. This reset spring force allows the water filtration mechanism 2 to squeeze the shredded kitchen waste inside, thereby achieving the pressure filtration of the liquid in the kitchen waste. After the water in the kitchen waste is pressure filtered out, the water filtration mechanism 2 can be opened to allow the third screw 108 to push the pressure-filtered kitchen waste out of the water filtration mechanism 2.

[0028] After multiple filtration cycles, the butterfly bolts securing the n-shaped cylinder 103 can be disassembled by the staff, allowing the water filtration mechanism 2 to be pulled out of the slide groove 109 for cleaning. This effectively prevents the water filtration mechanism 2 from being affected by the accumulation of dirt, thus extending its filtration efficiency and service life.

[0029] like Figure 4 As shown, the water filtration mechanism 2 includes a water filter cylinder 201, which is slidably installed in the slide groove 109. A top pressure block 204 is fixedly installed on the upper surface of the water filter cylinder 201. The top pressure block 204 slides out of the slide groove 109 and slides in the n-shaped cylinder 103. The n-shaped cylinder 103 is detached and installed on the upper surface of the connecting cylinder 1 by a butterfly bolt. The n-shaped cylinder 103 is connected to the slide groove 109.

[0030] A sliding column 205 is fixedly installed inside the n-shaped cylinder 103. The sliding column 205 slides through the top pressure block 204 and a spring 206 is fitted on its outer surface. One end of the spring 206 is fixedly connected to one end inside the n-shaped cylinder 103, and the other end touches one end of the top pressure block 204. A water filter hole 202 is opened at the lower end of the outer surface of the water filter cylinder 201. A sealing cover 203 is slidably installed at one end of the water filter cylinder 201 so that the sealing cover 203 can seal the end of the water filter cylinder 201.

[0031] Through the design of the filter cylinder 201, filter holes 202, sealing cover 203, top pressure block 204, and spring 206, after the secondary shredded kitchen waste is pushed into the third screw 108, the third screw 108 can push the secondary shredded kitchen waste into the filter cylinder 201. The filter cylinder 201 can slide out of the chute 109 by a corresponding length according to the volume of the kitchen waste to increase the storage capacity. The filter cylinder 201 is pushed out by the kitchen waste. As the filter cartridge 201 slides out of the groove 109, it will also cause the top pressure block 204, which is fixedly installed on the upper surface, to slide on the outer surface of the slide column 205 inside the n-shaped cylinder 103. This allows the top pressure block 204 to press against one end of the spring 206 fitted on the outer surface of the slide column 205. The spring 206 can then apply a restoring spring force to the top pressure block 204, pushing the filter cartridge 201 back into the groove 109. This allows the filter cartridge 201 to be pushed back into the groove 109 by the restoring spring force. The thrust is used to squeeze the shredded kitchen waste inside, thereby filtering out the liquid in the kitchen waste. The filtered water can be discharged from the filter holes 202 opened at the lower end of the outer surface of the filter cylinder 201. After the water in the kitchen waste is filtered out, the sealing cover 203 can be pulled out, allowing the third screw 108 to push the filtered kitchen waste out of the filter cylinder 201. After multiple filtrations, the butterfly bolts fixing the n-shaped cylinder 103 can be removed by the operator, allowing the operator to pull the n-shaped cylinder 103 to drive the internal sliding column 205 out of the top pressure block 204 of the filter cylinder 201. This releases the positional constraint of the filter cylinder 201, allowing the operator to pull the filter cylinder 201 out of the sliding groove 109 for cleaning. This reduces the residue of dirt and impurities on the filter holes 202, reduces the risk of bacterial growth, extends the service life of the filter cylinder 201, and improves the overall maintenance efficiency of the equipment.

[0032] Based on the above technical solution, the working steps of this solution are summarized as follows: When separating solid and liquid waste, the reduction motor 102 can be started to drive one set of first screws 104 to rotate. The rotation of the first screw 104 is driven by gears 105 fixedly mounted on its outer surface, which mesh with the gears 105 fixedly mounted on the outer surface of another set of first screws 104, causing them to rotate in a relatively meshing manner. This, in turn, causes the two sets of first screws 104 to drive the first spiral shear blade 106, the second screw 107, the second spiral shear blade 110, and the third screw 108 fixedly mounted at the other end to rotate in a relatively meshing manner. Afterwards, the kitchen waste can be poured from the kitchen waste dumping hopper 101 into the connecting cylinder. The food waste is first pushed into the first screw 104 by two sets of first screws 104. The food waste pushed by the first screw 104 enters the first spiral shear blade 106 and is shredded. At the same time, it is also pushed into the second screw 107, where the second screw 107 pushes the shredded food waste into the second spiral shear blade 110 for secondary shredding. The shredded food waste is then pushed into the third screw 108 by the spiral pushing force of the second spiral shear blade 110. During the pushing process, the spiral blade spacing between the first screw 104, second screw 107 and third screw 108 gradually decreases from 150mm to 100mm to 50mm, forming a gradient compression space. This causes the compressive force on the food waste to gradually increase from 1.2MPa to 3MPa during the pushing process.At 5MPa, water is squeezed out layer by layer, allowing the third screw 108 to push the secondary shredded kitchen waste back into the filter cartridge 201. The filter cartridge 201 can slide out of the chute 109 by a corresponding length according to the volume of the kitchen waste to increase its storage capacity. As the filter cartridge 201 is pushed out of the chute 109 by the kitchen waste, it also drives the top pressure block 204, which is fixedly installed on the upper surface, to slide on the outer surface of the slide column 205 inside the n-shaped cylinder 103. This allows the top pressure block 204 to press against one end of the spring 206 fitted on the outer surface of the slide column 205. The spring 206 applies a restoring spring force to the top pressure block 204, pushing the filter cartridge 201 back into the chute 109, thus allowing the filter cartridge 201 to pass through. The spring-loaded force of the filter presses and squeezes the shredded kitchen waste inside, thereby filtering out the liquid. The filtered water can then be discharged through the filter holes 202 at the lower end of the outer surface of the filter cylinder 201. After the water in the kitchen waste is filtered out, the sealing cover 203 can be pulled out, allowing the third screw 108 to push the filtered kitchen waste out of the filter cylinder 201. After multiple filtrations, the butterfly bolts fixing the n-shaped cylinder 103 can be removed by the operator, allowing the operator to pull the n-shaped cylinder 103 to pull the internal sliding column 205 out of the top pressure block 204 of the filter cylinder 201. This releases the positional constraint on the filter cylinder 201, allowing the operator to pull the filter cylinder 201 out of the sliding groove 109 for cleaning.

[0033] In summary: When filtering water from kitchen waste, the filter can chop the waste and compress it in stages, gradually compacting it from its initial loose state to ensure that water is fully squeezed out, greatly improving the efficiency of solid-liquid separation. After use, the filter cartridge 201 can be easily disassembled and cleaned, reducing the accumulation of dirt on the filter cartridge 201, preventing the filter holes 202 from clogging, maintaining the good filtration performance of the filter cartridge 201, and extending the service life of the filter cartridge 201.
