Description

Technical Field

[0001] This utility model relates to the field of pulping machine technology, specifically to an energy-saving and environmentally friendly pretreatment crushing and pulping machine for kitchen waste. Background Technology

[0002] Kitchen waste refers to the waste generated in daily life, food processing, catering services, and institutional catering. Its main sources are family kitchens, restaurants, hotels, canteens, markets, and other food-related industries. Kitchen waste contains extremely high levels of moisture and organic matter, making it easily perishable and producing a foul odor. With proper treatment and processing, it can be transformed into new resources. Its high organic matter content allows it to be used as fertilizer and animal feed after strict processing. It can also produce biogas for fuel or power generation, and the oil components can be used to prepare biofuels.

[0003] The crushing and pulping method is often used in the treatment of kitchen waste. This method involves crushing kitchen waste into a slurry and using the density difference to separate heavy and light materials. Heavy materials, which are particles that cannot be crushed, will sink to the bottom of the slurry, while light materials, such as oil, will adhere to the surface of the slurry. After crushing the slurry, it is only necessary to filter it in layers.

[0004] Because the oil content in kitchen waste varies, the thickness of the floating oil produced each time also varies. Traditional pulping machines are often unable to adapt to the different thicknesses of oil layers for suction and discharge, resulting in poor filtration. Furthermore, traditional pulping machines mostly use single mechanical crushing and pulping or single hydraulic pulping, and pulping methods that rely solely on one method are ineffective. To improve the above situation, an energy-saving and environmentally friendly pretreatment crushing and pulping machine for kitchen waste is proposed.

[0005] As disclosed in the authorization announcement number CN211612872U, a crushing and pulping machine for pretreatment of kitchen waste includes a shell. A first crushing wheel is rotatably connected between the two sides of the inner wall of the shell, and a second crushing wheel is rotatably connected between the two sides of the inner wall of the shell and located on top of the first crushing wheel. Gears are fixedly connected to the outer surface of one end of the first crushing wheel and the outer surface of one end of the second crushing wheel. The outer surfaces of the two gears mesh with each other. One end of the second crushing wheel penetrates the shell and extends to the outside of the shell.

[0006] Although it achieves the control of the pipe diameter by using the left and right movement of the baffle, so as to facilitate quantitative processing, it can effectively pre-treat kitchen waste by crushing, crushing thoroughly and greatly improving the crushing effect. It can be sorted and recycled, is simple to operate and easy to use, and is suitable for use in various large restaurants and hotels.

[0007] However, this does not solve the problem that existing pulping machines are not conducive to multi-stage crushing and pulping of kitchen waste, nor to the separate extraction and discharge of floating oil, thus affecting the environmental friendliness of kitchen waste treatment. Utility Model Content

[0008] The purpose of this utility model is to provide an energy-saving and environmentally friendly pretreatment crushing and pulping machine for kitchen waste, so as to solve the problems mentioned in the background art, which are not convenient for multi-stage crushing and pulping of kitchen waste, are not conducive to the separate suction and discharge of floating oil, and affect the environmental protection of kitchen waste treatment.

The top of the settling tank is equipped with a crushing tank, and the bottom of the settling tank is equipped with an electric valve. The top of the crushing tank is equipped with a crushing chamber, and a crusher is installed inside the crushing chamber. A water storage tank is installed on one side wall of the settling tank, and an oil storage tank is installed on the other side wall of the settling tank. A diversion ring is installed on the outer wall of the crushing tank. A second electric push rod is installed on the outer wall of the crushing tank on one side of the diversion ring. A second push arm is installed at the output end of the second electric push rod. A slip ring is movably installed at the end of the second push arm away from the second electric push rod, and the slip ring is slidably connected to the crushing tank. Multiple sets of linkage arms with equal spacing are movably installed on the outer wall of the slip ring. An adjusting arm is movably installed at the end of each linkage arm away from the slip ring.

[0010] Preferably, a water spray pipe is fixedly installed at the end of the adjusting arm away from the linkage arm, and one end of the water spray pipe extends into the interior of the crushing box and is movably connected to the crushing box, and the other end of the water spray pipe extends into the interior of the diverting ring and is movably connected to the diverting ring.

[0011] Preferably, a high-pressure water pump is installed at the top of the water storage tank, and the output end of the high-pressure water pump is connected to the diversion ring.

[0012] Preferably, the inside of the crushing box is provided with a mesh cylinder, and a first electric push rod is provided on the inner wall of the crushing box on one side of the mesh cylinder.

[0013] Preferably, a waterproof motor is provided at the bottom end of the mesh cylinder, and a blade stirring rack is installed at the output end of the waterproof motor.

[0014] Preferably, the output end of the first electric push rod is equipped with a first push arm, and the bottom end of the first push arm is provided with a placement bracket.

[0015] Preferably, a liquid level sensor is provided at the bottom of the placement rack, and a suction tube is provided at the bottom of the placement rack on one side of the liquid level sensor.

[0016] Preferably, a suction pump is provided at the top of the oil storage tank, and a flexible hose is installed at the input end of the suction pump.

[0017] Preferably, the flexible hose extends into the interior of the grinding chamber and is connected to the suction tube.

[0018] Preferably, a PLC controller is installed on the outer wall of the water storage tank, and the output terminal of the PLC controller is electrically connected to the input terminals of the high-pressure water pump, the suction pump, the first electric push rod, the waterproof motor, the electric valve, the crusher, the second electric push rod, and the liquid level sensor.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the pulping machine not only realizes multi-stage crushing and pulping of kitchen waste, facilitating the separate suction and discharge of floating oil, but also improves the environmental friendliness of kitchen waste treatment.

[0020] (1) When it is necessary to crush and pulp kitchen waste, the kitchen waste is put into the crusher and the crusher performs preliminary crushing of the kitchen waste. After preliminary crushing, the kitchen waste falls down through the crusher. During the falling process, the high-pressure water pump pressurizes the water in the water storage tank and sprays it into the diversion ring. The high-pressure water flow is diverted through the diversion ring to multiple sets of water spray pipes and sprayed out from the water spray pipes to form multiple water jets. Under the impact of the high-pressure water jets, the kitchen waste is subjected to secondary crushing treatment. Because the water spray pipes are curved, the initial state of the water jets is that multiple sets of water jets converge at the center point, which can effectively crush the waste falling from the center. When it is necessary to adjust the convergence point of the water jets, the second electric push rod drives the second push arm to move. The second push arm drives the slip ring to slide on the surface of the crushing box. The slip ring carries Multiple sets of linkage arms rotate synchronously. The linkage arms drive the water spray pipes to rotate via adjusting arms, thereby adjusting the spray direction of the water spray pipes and the convergence point of multiple water jets. When the convergence point of the water jets shifts from the center point to the periphery, the falling kitchen waste can be thoroughly crushed. The kitchen waste, after secondary crushing, falls into the mesh cylinder along with water. A waterproof motor drives the blade agitator to rotate, which performs tertiary crushing and agitation of the kitchen waste, mixing it with the water flow to form a slurry that falls into the settling tank. This completes the crushing and slurrying process of the kitchen waste. The above design can perform multi-stage crushing and slurrying of kitchen waste, improve the uniformity of crushing, and flexibly adjust the convergence point of the water jets for better crushing of kitchen waste.

[0021] (2) After the slurry has been settling in the settling tank for a certain period of time, according to the principle of gravity, the heavy objects in the slurry settle to the bottom layer, the water remains in the middle layer, and the oil floats to the surface of the slurry. At this time, the level sensor senses the level of the floating oil and sends the data to the PLC controller. The first electric push rod drives the first push arm to move downward, the first push arm drives the placement frame to move downward, and the placement frame drives the level sensor and the suction pipe to move downward, so that the suction pipe is immersed in the floating oil layer. The suction pump then draws the floating oil into the oil storage tank through the flexible hose and the suction pipe for storage. As the oil level drops, the level sensor continuously senses the level data and sends signals to the PLC controller. The PLC controller then controls the simultaneous detection and suction of the floating oil, achieving the function of simultaneous detection and suction. After the floating oil is suctioned out, the electric valve is opened, and the bottom layer of heavy objects and the middle layer of water are discharged through the electric valve. The above design allows for the separate suction and discharge of floating oil, preventing it from affecting the discharge of other substances in the slurry. This reduces the difficulty of food waste treatment and improves the environmental friendliness of food waste treatment. Attached Figure Description

[0031] Example 1

[0032] Please see Figures 1 to 5This utility model provides an embodiment of an energy-saving and environmentally friendly pretreatment crushing and pulping machine for kitchen waste, comprising a settling tank 1 and a crushing tank 2. The crushing tank 2 is located at the top of the settling tank 1, and an electric valve 13 is located at the bottom of the settling tank 1. The crushing tank 3 is located at the top of the crushing tank 2, and a crusher 8 is installed inside the crushing tank 3. A water storage tank 6 is located on one side wall of the settling tank 1, and an oil storage tank 14 is located on the other side wall of the settling tank 1. A diversion ring 4 is located on the outer wall of the crushing tank 2, and a second electric push rod 17 is located on the outer wall of the crushing tank 2 on one side of the diversion ring 4. A second push arm 22 is installed at the output end of the second electric push rod 17. A slip ring 23 is movably installed at the end of the 22 furthest from the second electric push rod 17, and the slip ring 23 is slidably connected to the crushing box 2. Multiple sets of linkage arms 24 with equal spacing are movably installed on the outer wall of the slip ring 23. An adjusting arm 25 is movably installed at the end of the linkage arm 24 furthest from the slip ring 23. A water spray pipe 26 is fixedly installed at the end of the adjusting arm 25 furthest from the linkage arm 24. One end of the water spray pipe 26 extends into the interior of the crushing box 2 and is movably connected to the crushing box 2. The other end of the water spray pipe 26 extends into the interior of the diversion ring 4 and is movably connected to the diversion ring 4. A high-pressure water pump 5 is installed at the top of the water storage tank 6, and the output end of the high-pressure water pump 5 is connected to the diversion ring 4.

[0033] In this utility model, the PLC controller 7 is a Siemens S7-200, which is existing technology. Therefore, its internal structure, working principle, and connection and control method with the electrical components in this application will not be described in detail. When it is necessary to crush and pulp kitchen waste, the kitchen waste is put into the crusher 8, which performs preliminary crushing. The crushed kitchen waste falls downward through the crusher 8. During the falling process, the high-pressure water pump 5 is turned on, and the high-pressure water pump 5 pumps... Water in the storage tank 6 is pressurized and sprayed into the diversion ring 4. The high-pressure water flow is then diverted through the diversion ring 4 to multiple sets of spray pipes 26 and sprayed out from the spray pipes 26 to form multiple water jets. Under the impact of the high-pressure water jets, the kitchen waste undergoes secondary crushing. Because the spray pipes 26 are curved, the initial state of the water jets is that multiple sets of water jets converge at the center point, which can effectively crush the waste falling from the center. When it is necessary to adjust the convergence point of the water jets, the second electric push rod 17 is opened. 17 drives the second push arm 22 to move, and the second push arm 22 drives the slip ring 23 to slide on the surface of the crushing box 2. The slip ring 23 drives multiple sets of linkage arms 24 to rotate synchronously. The linkage arms 24 drive the water spray pipe 26 to rotate through the adjusting arm 25, thereby adjusting the spray direction of the water spray pipe 26 and thus adjusting the convergence point of multiple sets of water jets. When the convergence point of the water jets shifts from the center point to the periphery, the falling kitchen waste can be fully crushed. The kitchen waste that has been crushed twice and water fall into the mesh cylinder 11. At this time, the waterproof motor 12 is turned on, and the waterproof motor 12 drives the blade stirring frame 10 to rotate. The blade stirring frame 10 crushes the kitchen waste in three stages and stirs it to mix it with the water flow to form a slurry that falls into the settling tank 1, thus completing the crushing and pulping of the kitchen waste. The above design can crush and pulp the kitchen waste in multiple stages, which can improve the uniformity of the crushing of the kitchen waste and can also flexibly adjust the convergence point of the water jets to crush the kitchen waste better.

[0034] The inside of the crushing box 2 is provided with a mesh cylinder 11, and a first electric push rod 9 is provided on the inner wall of the crushing box 2 on one side of the mesh cylinder 11;

[0035] A waterproof motor 12 is installed at the bottom of the mesh cylinder 11, and a blade stirring rack 10 is installed at the output end of the waterproof motor 12.

[0036] The output end of the first electric push rod 9 is equipped with a first push arm 18, the bottom end of the first push arm 18 is provided with a placement rack 19, the bottom end of the placement rack 19 is provided with a liquid level sensor 20, and the bottom end of the placement rack 19 on one side of the liquid level sensor 20 is provided with a suction pipe 21.

[0037] A suction pump 15 is installed at the top of the oil storage tank 14. A flexible hose 16 is installed at the input end of the suction pump 15. The flexible hose 16 extends into the interior of the crushing box 2 and is connected to the suction pipe 21.

[0038] A PLC controller 7 is installed on the outer wall of the water storage tank 6, and the output terminal of the PLC controller 7 is electrically connected to the input terminal of the high-pressure water pump 5, the suction pump 15, the first electric push rod 9, the waterproof motor 12, the electric valve 13, the crusher 8, the second electric push rod 17, and the liquid level sensor 20.

[0039] After the slurry has been settling in the settling tank 1 for a certain period of time, according to the principle of gravity, the heavier objects in the slurry settle to the bottom, the water remains in the middle layer, and the oil floats to the surface of the slurry. At this time, the level sensor 20 senses the level of the floating oil and sends the data to the PLC controller 7. The PLC controller 7 analyzes the signal and opens the first electric push rod 9. The first electric push rod 9 drives the first push arm 18 to move downward, which in turn drives the placement frame 19 to move downward. The placement frame 19 then drives the level sensor 20 and the suction pipe 21 to move downward, so that the suction pipe 21 is immersed in the floating oil layer. The suction pump 15 is then turned on, and the oil flows through a flexible... Pipe 16 and suction pipe 21 draw the floating oil into the oil storage tank 14 for storage. As the floating oil level drops, the level sensor 20 continuously senses the level data and continuously sends signals to the PLC controller 7. That is, the PLC controller 7 controls the simultaneous detection and suction of the floating oil level to achieve the function of simultaneous detection and suction. After the floating oil is suctioned out, the electric valve 13 is opened, and the bottom heavy objects and the middle water are discharged through the electric valve 13. The above design can separately suction out the floating oil, avoiding the floating oil from affecting the discharge of other substances in the slurry, reducing the difficulty of food waste treatment and improving the environmental friendliness of food waste treatment.

[0040] Work steps

[0041] When food waste needs to be crushed and pulped, it is fed into the crusher 8 for initial crushing. The crushed food waste then falls downwards through the crusher 8. During this fall, a high-pressure water pump 5 pressurizes water from the storage tank 6 and sprays it into the diversion ring 4. The high-pressure water flow is then distributed through the diversion ring 4 to multiple sets of spray pipes 26, forming multiple water jets. Under the impact of these high-pressure water jets, the food waste undergoes secondary crushing. Because the spray pipes 26 are curved, the initial state of the water jets is that multiple water jets converge at the center point, effectively crushing the waste falling from the center. When the convergence point of the water jets needs to be adjusted, the second electric push rod 17 drives the second push arm 22 to move, which in turn drives the slip ring 23 to slide on the surface of the pulverizing chamber 2. The slip ring 23 drives multiple sets of linkage arms 24 to rotate synchronously, and the linkage arms 24 drive the water spray pipe 26 to rotate via the adjusting arm 25, thereby adjusting the spray direction of the water spray pipe 26 and thus adjusting the convergence point of the multiple sets of water jets. When the convergence point of the water jets shifts from the center point to the surrounding area, the falling kitchen waste can be fully crushed. The kitchen waste that has undergone secondary crushing falls into the mesh cylinder 11 along with the water, where the waterproof motor 12 drives the blades to stir. The frame 10 rotates, and the blade mixing frame 10 performs three-stage crushing and mixing of the kitchen waste, causing it to mix with water to form a slurry that falls into the settling tank 1, thus completing the crushing and slurry preparation of the kitchen waste. The slurry remains in the settling tank 1 for a certain period of time. According to the principle of gravity, the heavier objects in the slurry settle to the bottom, the water remains in the middle layer, and the grease floats to the surface. At this time, the liquid level sensor 20 senses the level of the floating oil and sends the data to the PLC controller 7. The first electric push rod 9 drives the first push arm 18 to move downwards, which in turn drives the placement frame 19 to move downwards. The placement frame 19 then drives the liquid level sensor 20 and the pump... The suction pipe 21 moves downwards to immerse itself in the oil layer. The suction pump 15 then draws the oil through the flexible hose 16 and the suction pipe 21 into the oil storage tank 14 for storage. As the oil level drops, the level sensor 20 continuously senses the level data and sends signals to the PLC controller 7. The PLC controller 7 controls the simultaneous detection and suction of the oil level, achieving the function of simultaneous detection and suction. After the oil is suctioned out, the electric valve 13 is opened, and the bottom layer of heavy objects and the middle layer of water are discharged through the electric valve 13. The above is the complete usage of the energy-saving and environmentally friendly pretreatment crushing and pulping machine for kitchen waste.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
