Description

Technical Field

[0001] The present application relates to the field of garbage disposal equipment, and in particular to a kitchen waste crushing device. Background Art

[0002] In the daily operation of the catering industry, a large amount of kitchen waste is generated every day. If the kitchen waste is discharged directly, it is very easy to cause serious pollution to the environment and also lead to waste of resources. The current common practice is to collect and transport it to a professional treatment plant, and then perform harmless biological treatment on it, and finally convert it into products such as biofertilizer.

[0003] When the food waste is transported to the processing plant, it needs to be transferred to various processing equipment with the help of a specific conveying device for corresponding processing. Considering that the large volume of food waste will interfere with the normal transportation of food waste, before sending the food waste to the conveying equipment, it is generally crushed by a double-roll crusher to reduce the overall particle size of the food waste.

[0004] Regarding the above-mentioned related technologies, kitchen waste often contains a lot of oil and water, which mix with the crushed waste, causing the crushed waste to easily adhere to the crushing rollers and other key parts of the double-roll crusher. This not only affects the crushing efficiency of the subsequent double-roll crusher, but also makes the subsequent cleaning of the double-roll crusher extremely difficult. Therefore, there is room for improvement. Summary of the invention

[0005] In order to limit garbage from adhering to the crushing roller of the double-roll crusher and facilitate the double-roll crusher to better crush the kitchen waste, the present application provides a kitchen waste crushing device.

[0006] The present application provides a kitchen waste crushing device, which adopts the following technical solution: A kitchen waste crushing device, comprising a solid-liquid separation mechanism and a crushing mechanism; The solid-liquid separation mechanism comprises a filtrate box and a liquid collecting box, wherein a plurality of filter holes are distributed on the bottom wall of the filtrate box; a feed inlet is provided on the top of the filtrate box; a discharge outlet is provided at one end of the filtrate box; a pushing assembly is also provided in the filtrate box, and the pushing assembly is used to push the kitchen waste in the filtrate box out of the discharge outlet; the liquid collecting box is supported at the bottom of the filtrate box, and the liquid collecting box is used to receive the oil and water filtered out of the filter holes of the filtrate box; The crushing mechanism comprises a double-roll crusher and a collecting box; the feeding end of the double-roll crusher is connected with the discharging port of the filtrate box, and the collecting box is located below the discharging end of the double-roll crusher.

[0007] By adopting the above technical scheme, when the kitchen waste is put into the filtrate box from the feed port at the top of the filtrate box, the oil and water mixed in the kitchen waste can flow into the collecting box below through multiple filter holes at the bottom of the filtrate box for storage; then, the kitchen waste after most of the oil and water are removed is gradually pushed to the discharge port of the filtrate box by relying on the pushing assembly, and falls into the double-roll crusher for crushing, which effectively limits the oil and water from mixing with the kitchen waste into the crushing stage, reduces the situation where the internal components of the double-roll crusher are adhered to the garbage due to excessive oil and water content, and facilitates the double-roll crusher to better crush the garbage.

[0008] Preferably, the filtrate box is movably supported with a baffle plate corresponding to the discharge port, and the baffle plate blocks the discharge port; the pushing assembly includes a pushing plate and a pushing drive member, the pushing plate is supported in the inner cavity of the filtrate box, and the outer peripheral side of the pushing plate is abutted against the inner peripheral side of the filtrate box; the pushing drive member is drivingly connected to the pushing plate, and the pushing drive member is used to drive the pushing plate to move toward or away from the discharge port.

[0009] By adopting the above technical solution, during the pushing process of the pushing assembly, the pushing plate and the baffle plate are first used to squeeze the kitchen waste, so as to further reduce the oil and water content in the waste and improve the compactness of the kitchen waste. After the squeezing is completed, the baffle plate is moved out of the discharge port of the filtrate box, and the pushing drive member drives the pushing plate to move further toward the discharge port to push the pre-treated kitchen waste out of the discharge port, which is beneficial to further reduce the oil and water content in the kitchen waste and facilitate better removal of the kitchen waste from the filtrate box.

[0010] Preferably, the solid-liquid separation mechanism also includes a casing box, which is sleeved on the outer periphery of the filtrate box, and the liquid collecting box is connected to the bottom of the casing box; the filter holes are also distributed on the opposite side walls of the filtrate box; the opposite side walls of the filtrate box respectively leave gaps with the opposite side walls of the casing box.

[0011] By adopting the above technical solution, the oil and water in the kitchen waste can be discharged from the bottom of the filtrate box, and can also be discharged through the filter holes on the side wall of the filtrate box and flow into the collecting box, which is beneficial to increase the overall filtrate area of ​​the filtrate box and reduce the problem of reduced oil-water separation effect due to the filter holes at the bottom of the filtrate box being covered and blocked by kitchen waste.

[0012] Preferably, the discharge port of the filtrate box is connected to a transfer box, and the feed end of the double-roll crusher is connected to the bottom of the transfer box.

[0013] By adopting the above technical solution and setting up the transfer box, the kitchen waste pushed out from the discharge port of the filtrate box can fall into the double-roll crusher in a relatively closed space, which is beneficial to reduce the splashing of waste during the transfer process and curb the emission of odor.

[0014] Preferably, a mounting opening is provided on the top of the transfer box, a guide fan is installed on the mounting opening, and the guide fan is arranged opposite to the double-roll crusher.

[0015] By adopting the above technical solution, the guide fan is used to continuously blow air toward the double-roll crusher to accelerate the air flow inside the transfer box, which is helpful to accelerate the kitchen waste falling through the discharge port to enter the double-roll crusher. At the same time, it is helpful to reduce the situation where the waste is splashed onto the inner wall of the transfer box due to inertia during the crushing process.

[0016] Preferably, a flushing assembly is provided on the side of the push plate facing away from the baffle plate, the flushing assembly includes a flushing pipe, the flushing pipe is connected to an air source, a plurality of flushing air nozzles are connected to the periphery of the flushing pipe; the flushing pipe includes a horizontal pipe section and two vertical pipe sections, the flushing air nozzles of the horizontal pipe section are arranged toward the bottom wall of the filtrate box; the flushing air nozzles of the two vertical pipe sections are respectively arranged toward the opposite side walls of the filtrate box.

[0017] By adopting the above technical solution, the push plate moves toward the baffle plate to cooperate with the baffle plate to squeeze the kitchen waste in the filtrate box. In the process, some kitchen waste is easily squeezed into and stuck in the filter holes, causing the filter holes to be blocked. Through the setting of the flushing component, during the subsequent sliding process of the push plate, the horizontal pipe section and the vertical pipe section of the flushing pipe can be used to flush the filter holes at the bottom and sides of the filtrate box respectively, so as to blow the garbage blocked in the filter holes out of the filter holes, thereby reducing the impact of filter hole blockage on subsequent oil and water outflow.

[0018] Preferably, an intercepting filter plate is supported on the top of the inner cavity of the liquid collecting box.

[0019] By adopting the above technical solution, an intercepting filter plate is supported on the top of the liquid collecting tank, and the intercepting filter plate is used to intercept and process the garbage blown out of the filter holes through the flushing pipe, which is helpful to reduce the situation where the garbage falling from the filter holes is mixed with the oil and water in the liquid collecting tank.

[0020] Preferably, the discharge end of the double-roll crusher is connected to a discharge pipe, the collecting box is located below the discharge pipe, a blowing assembly is installed in the discharge pipe, the blowing assembly includes a blowing pipe horizontally supported in the discharge pipe, and a plurality of blowing air nozzles are connected to the outer periphery of the blowing pipe; a rotary driving member is installed on the discharge pipe corresponding to the blowing pipe, the rotary driving member is drivingly connected to the blowing pipe, and the rotary driving member is used to drive the blowing pipe to rotate around its own axis.

[0021] By adopting the above technical scheme, when the rotary driving member drives the blow pipe to rotate until the blow nozzle is facing the crushing roller of the double-roll crusher, the garbage adhered to the crushing roller can be blown and cleaned through the blow pipe; when the rotary driving member drives the blow pipe to rotate until the blow nozzle is facing into the collecting box, compressed air can be blown into the collecting box through the blow pipe to drive the material in the collecting box to move downward, which is beneficial to improve the compactness of the food waste inside the collecting box, thereby allowing the collecting box to collect more crushed food waste.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Before crushing the kitchen waste, first filter out the oil and water in the kitchen waste through the filtrate box, and then use the pushing component to push the kitchen waste with the oil and water filtered out through the filtrate box outlet into the double-roll crusher for crushing. This helps to reduce the adhesion of oil and water to the inside of the double-roll crusher after the subsequent crushing of the waste, making it easier for the double-roll crusher to crush the waste.

[0023] 2. Through the setting of the pushing component, the pushing component is used in conjunction with the baffle plate to extrude the kitchen waste to further separate the oil and water components therein and improve the compactness of the kitchen waste. After the extrusion is completed, the baffle plate is removed and the pushing component continues to push the kitchen waste out of the discharge port of the filtrate box, which not only reduces the amount of residual oil and water in the waste, but also improves the stability and efficiency of the entire transportation process.

[0024] 3. Through the setting of the blowing assembly in the discharge pipe, when the blowing pipe is rotated to the blowing nozzle facing the crushing roller, the residual garbage adhering to the surface of the crushing roller can be removed through the blowing pipe, reducing the situation where the normal operation of the crushing roller is affected by the adhesion of garbage. When the blowing pipe is rotated to the blowing nozzle pointing to the inside of the collection box, compressed air can be blown into the collection box through the blowing assembly to make the kitchen waste in the collection box more compactly stacked, which is conducive to improving the space utilization rate of the collection box.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The present application discloses a kitchen waste crushing device, referring to Figure 1 and Figure 2 , including an oil-water separation mechanism and a crushing mechanism. The oil-water separation mechanism includes a casing 10, a filtrate box 11 and a collecting box 12. The filtrate box 11 is supported in the casing 10. The bottom box wall of the filtrate box 11 and the box walls on both sides are distributed with a plurality of filtrate holes. The collecting box 12 is connected to the bottom of the casing 10 and is used to collect the oil-water mixture filtered out of the filter holes of the filtrate box 11; a feed port is provided at the top of the filtrate box 11, and a discharge port is provided at one end of the filtrate box 11. A pushing assembly 3 is also supported in the filtrate box 11, and the pushing assembly 3 is used to push the garbage in the filtrate box 11 out of the discharge port; the crushing mechanism includes a double-roll crusher 21 and a collecting box 22. The feed end of the double-roll crusher 21 is connected with the discharge port of the filtrate box 11 to receive the kitchen waste discharged from the discharge port of the filtrate box 11; the collecting box 22 is located below the discharge end of the double-roll crusher 21 and is used to receive the kitchen waste crushed by the double-roll crusher 21.

[0033] The kitchen waste to be processed is placed into the filtrate box 11 through the feed port. After the oil and water carried in the kitchen waste are filtered out by the filter holes of the filtrate box 11, the kitchen waste is pushed into the double-roll crusher through the discharge port of the filtrate box 11 by the pushing component 3 for crushing, thereby effectively reducing the situation in which the kitchen waste is easily adhered to the crushing rollers of the double-roll crusher due to oil and water.

[0034] Reference Figure 2 and Figure 3, a plurality of supporting square tubes are welded at the bottom of the casing 10, and the bottom of the filtrate box 11 is welded on the plurality of supporting square tubes, so that the filtrate box 11 is stably supported in the casing 10. One end of the filtrate box 11 with a discharge port is passed through the casing 10. The casing 10 has gaps with the two opposite sides of the box wall and the two opposite sides of the filter box, so that the oil and water flowing out through the filter holes of the two opposite sides of the box wall of the filtrate box 11 can flow into the collecting box 12 through the gap between the casing 10 and the filtrate box 11, effectively reducing the situation where the filter holes of the bottom box wall of the filtrate box 11 are covered by kitchen waste, resulting in limited oil and water filtration.

[0035] The top feed port of the filtrate box 11 is connected with a feed pipe 111 , which is passed through the casing 10 and is in the shape of a funnel with the tip facing downward, so that kitchen waste can be poured into the filtrate box 11 through the feed pipe 111 .

[0036] A baffle plate 4 is movably supported at the filtrate box 11 corresponding to the discharge port, and the baffle plate 4 blocks the discharge port. The top of the baffle plate 4 is penetrated through the top of the filtrate box 11. The filtrate box 11 is provided with a movable driving component 41 corresponding to the baffle plate 4. The movable driving component 41 includes a movable cylinder vertically supported upward on the outside of the filtrate box 11. The piston rod of the movable cylinder is connected to the top of the baffle plate 4 through a connecting piece to drive the baffle plate 4 to move up and down.

[0037] The pushing assembly 3 includes a pushing plate 31 and a pushing driving member 32. The outer peripheral side of the pushing plate 31 is abutted against the inner peripheral side of the filtrate box 11. The pushing driving member 32 is used to drive the pushing plate 31 to move toward or away from the discharge port. Specifically, the pushing driving member 32 includes a pushing cylinder, which is fixed to one end of the filtrate box 11 away from the discharge port through a bracket, and the pushing cylinder piston rod is connected to the pushing plate 31.

[0038] Before the push assembly 3 pushes the kitchen waste out of the discharge port, the movable driving member 41 first drives the baffle plate 4 to block the discharge port, and the push driving member 32 drives the push plate 31 to move toward the baffle plate 4, and the push plate 31 cooperates with the baffle plate 4 to squeeze the kitchen waste in the inner cavity of the filtrate box 11 to further reduce the oil and water content in the kitchen waste; after the squeezing is completed, the baffle plate 4 is driven upward by the movable driving member 41 to open the discharge port. The push driving member 32 drives the push plate 31 to continue to move toward the discharge port until the kitchen waste is pushed out through the discharge port.

[0039] Reference Figure 3 and Figure 4The baffle plate 4 is also provided with a flushing assembly, which includes a flushing pipe 5, which is fixed to the side of the push plate 31 away from the baffle plate 4 through a pipe hoop, and is connected to the air source. The outer periphery of the flushing pipe 5 is evenly connected with a plurality of flushing air nozzles 51; the flushing pipe 5 includes a horizontal pipe section and two vertical pipe sections, and the two vertical pipe sections are respectively located at both ends of the horizontal pipe section. The flushing air nozzles 51 at the horizontal pipe section of the flushing pipe 5 are arranged toward the bottom wall of the filtrate box 11, and the flushing air nozzles 51 at the two vertical pipe sections of the flushing pipe 5 are respectively arranged toward the opposite sides of the filtrate box 11. Through the above arrangement, in the process of subsequent pushing plate 31 moving toward pushing plate 31, the filter holes on the bottom of the filtrate box 11 and the opposite side walls can be flushed through the flushing pipe 5 to blow the kitchen waste blocked in the filter holes out of the filter holes, thereby reducing the impact of filter hole blockage on subsequent oil and water filtration, and when the subsequent pushing plate 31 retreats and resets, the kitchen waste in the filter holes is brought to the side of the pushing plate 31 away from the baffle plate 4, causing cleaning difficulties.

[0040] The bottom of the liquid collecting box 12 is connected with a liquid outlet pipe 121, which is convenient for discharging the oil and water collected in the liquid collecting box 12. An interception filter plate 122 is supported on the top of the inner cavity of the liquid collecting box 12. The interception filter plate 122 is used to intercept the kitchen waste flushed out of the filter hole by the flushing component, and limit the situation where the kitchen waste falls into the liquid collecting box 12 and pollutes the oil and water collected in the liquid collecting box 12. A socket is provided on the outer side of the liquid collecting box 12 corresponding to the interception filter plate 122. The interception filter plate 122 is inserted into the inner cavity of the liquid collecting box 12 through the socket and the socket is blocked, so that the interception filter plate 122 can be pulled out from the liquid collecting box 12 later to clean up the garbage intercepted by the interception filter plate 122.

[0041] Reference Figure 2 and Figure 3 The end of the discharge port of the filtrate box 11 is connected to a transfer box 13; the feed end of the double-roll crusher 21 is connected to the bottom of the transfer box 13. The setting of the transfer box 13 allows the kitchen waste pushed out to the discharge port of the filtrate box 11 by the pushing assembly 3 to fall into the double-roll crusher 21 in a relatively closed state, which is conducive to reducing the scattering of kitchen waste when it falls from the discharge port of the filtrate box 11 into the double-roll crusher 21, and at the same time reduces the risk of odor diffusion and pollution.

[0042] An installation opening is opened at the top of the transfer box 13, and a guide fan 131 is installed in the installation opening. The guide fan 131 is arranged opposite to the double-roll crusher 21 located at the bottom of the transfer box 13. When the subsequent kitchen waste falls into the double-roll crusher 21, the guide fan 131 can be used to continuously blow airflow toward the double-roll crusher 21, which is beneficial to further limit the splashing of the kitchen waste when it falls into the double-roll crusher 21, and facilitate the kitchen waste to better enter the two crushing rollers of the double-roll crusher 21 for crushing processing.

[0043] Reference Figure 2and Figure 5 The bottom of the discharge end of the double-roll crusher 21 is also connected to a discharge pipe 23; the collection box 22 is located below the discharge pipe 23 and is used to receive the crushed kitchen waste discharged from the double-roll crusher 21 through the discharge pipe 23. A plurality of universal wheels are installed at the bottom of the collection box 22 to facilitate the subsequent overall movement of the collection box 22.

[0044] A blowing assembly is arranged in the discharge pipe 23, and the blowing assembly includes two blowing pipes 6 horizontally supported in the discharge pipe 23, and a plurality of blowing air nozzles 61 are connected to the outer periphery of the blowing pipes 6; the blowing pipes 6 are connected to an air source; the two blowing pipes 6 are respectively located below the two crushing rollers of the double-roll crusher 21, and the two blowing pipes 6 are respectively arranged in parallel with the two crushing rollers of the double-roll crusher 21, and both ends of the blowing pipes 6 are respectively rotatably connected to the opposite side walls of the discharge pipe 23 through bearings; the discharge pipe 23 is also provided with two rotary driving members 60 corresponding to the two discharge pipes 23, and the two rotary driving members 60 are respectively drivingly connected to the two discharge pipes 23, and are used to drive the corresponding discharge pipe 23 to rotate around its own axis; in this embodiment, the rotary driving member 60 adopts a reduction motor, the reduction motor is installed on the outside of the discharge pipe 23, and the output end of the reduction motor is connected to the corresponding end of the blowing pipe 6 through a coupling.

[0045] Through the setting of the blowing assembly, on the one hand, the corresponding blowing pipe 6 can be driven by the rotary driving part 60 to rotate so that the blowing air nozzle 61 is facing upward to the corresponding crushing roller, and the blowing pipe 6 blows compressed air toward the corresponding crushing roller through the blowing air nozzle 61 to clean the crushing roller and further reduce the garbage residue on the crushing roller; on the other hand, the corresponding blowing pipe 6 can be driven by the rotary driving part 60 to rotate so that the blowing air nozzle 61 is facing the collecting box 22, and the blowing pipe 6 blows compressed air into the collecting box 22 through the blowing air nozzle 61 to improve the compactness of the garbage inside the collecting box 22, which is conducive to the collecting box 22 to collect more kitchen waste.

[0046] The implementation principle of the embodiment of the present application is as follows: after the to-be-processed kitchen waste is fed into the filtrate box 11 through the feed pipe 111, the push plate 31 is driven by the push driving member 32 to move toward the direction close to the discharge port of the filtrate box 11, and the push plate 31 and the baffle plate 4 are used to squeeze the kitchen waste so that the oil and water inside the kitchen waste pass through the filter holes on the filtrate box 11 and fall into the collecting box 12; then, the baffle plate 4 is driven by the movable driving member 41 to move out of the discharge port of the filtrate box 11 to open the discharge pipe 23, and the push plate 31 is driven by the push driving member 32 to move further toward the discharge port of the filtrate box 11, so as to push the kitchen waste into the double-roll crusher 21 through the discharge port, and the waste is crushed by the double-roll crusher 21.

[0047] By separating the oil and water contained in the kitchen waste before crushing it, it is beneficial to improve the overall dryness of the kitchen waste and reduce the adhesion of the subsequent kitchen waste to the double-roll crusher 21 during the crushing process, thereby facilitating better crushing of the kitchen waste by the double-roll crusher 21.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
