Description

Technical Field

[0001] This invention relates to the field of waste transportation and treatment technology, and in particular to an integrated compression method for kitchen waste, used to compress and process kitchen waste or other similar household waste with high liquid content. Background Technology

[0002] Existing waste compression stations use multiple batches of waste directly compressed into mobile containers. This multiple-batch compression process often leads to overflow, especially with high-liquidity kitchen waste or other household waste. Frequent overflows during container transport increase manual cleaning costs and cause secondary environmental pollution. Furthermore, directly stacking high-moisture waste into the containers places high demands on leak-proof design and limits the amount of waste they can hold. Therefore, a pre-treatment process for this type of waste needs to be designed to compress and drain the liquid, thereby increasing waste transfer capacity. Summary of the Invention

[0003] This invention addresses the problems of leakage and contamination of high-liquidity kitchen waste in existing technologies, as well as the inconvenience of transportation. It provides an integrated compression method for kitchen waste, which aims to pre-treat high-moisture kitchen waste transported from waste transfer stations by compression.

[0004] The objective of this invention is achieved by providing an integrated compression method for kitchen waste, characterized by comprising the following processes:

[0005] S1: The waste collection device pours the waste into the feed inlet of the compression chamber and fills the compression chamber at the inlet.

[0006] S2: The waste in the compression chamber is pre-compressed and drained through the compression component;

[0007] S3: The pre-extruded material is pushed forward into the full-material forming chamber for a second pre-extruded process;

[0008] S4: The compression component resets and repeats the S1 to S3 process until the full material forming chamber is filled with the extruded material.

[0009] S5: The mobile box is connected to the discharge end of the full material forming silo. The gates connecting the discharge end of the full material forming silo and the feed end of the mobile box are opened. The compression component further squeezes and pushes the material in the discharge direction, pushing the material into the mobile box. The material is then stacked and filled in the mobile box from the innermost end to the outermost end.

[0010] S6: Repeat the process from S1 to S5 until the moving box is filled with the compressed material, then release the clamping device and the moving box leaves.

[0011] Furthermore, the compression method is achieved through continuous compression using an integrated kitchen waste compression system, including a compression chamber. The upper side of the inlet end of the compression chamber has an inlet for installing a receiving hopper. A compression component is located on the outer side of the inlet end of the compression chamber, comprising a compression pusher and a compression cylinder. The compression cylinder horizontally pushes the compression pusher. The other end of the compression chamber is integrally formed into a full-material forming chamber via a first gate. A second gate is located at the outlet end of the full-material forming chamber. Above the first and second gates are respectively a first lifting mechanism and a second lifting mechanism for raising and lowering the corresponding gates. A third lifting mechanism is located at the outlet end outside the second gate for raising and lowering the receiving gate of the movable collection box. Several drainage holes are provided on the side walls, bottom wall, and first gate wall of the compression chamber. A collection hopper is located on the bottom side of the compression chamber. Clamping mechanisms that mate with the interface of the movable collection box are provided on the two outer side walls of the full-material forming chamber. A first position sensor and a second position sensor are respectively located on the left side walls of the first and second gates. A third position sensor is located on the left side of the third lifting mechanism.

[0012] To facilitate the first pre-compression of the waste, before the start of process S1, the first and second gates are closed, and the pusher head is located in the initial position on the left side of the feed inlet; during process S2, the pre-compression force of the compression cylinder is set to f1. When the pre-compression force reaches f1 and the compression pusher head stops moving, the pre-compression is completed, and the process proceeds to S3.

[0013] To facilitate the material pushing and the second pre-extrusion, during process S3, the first lifting mechanism raises the first gate to fully open, and the extrusion cylinder continues to push the pre-extruded material forward until it is pushed against the second gate and the extrusion pusher stops moving. When the extrusion pressure of the extrusion cylinder reaches f2 and f2 > f1, the extrusion cylinder retracts to the position of the first position sensor. At the same time, the first lifting mechanism lowers the first gate until it is fully closed, and the extrusion cylinder continues to drive the extrusion pusher back to the initial position to continue receiving material and repeating the process of S1 to S3.

[0014] To facilitate the determination of whether the full material forming chamber is full, during process S4, when process S3 is repeated, if the extrusion pusher stops and reaches the f2 pushing force, but the position of the extrusion pusher has not reached the first sensor, it is determined that the full material forming chamber is full, and the process proceeds to process S5.

[0015] To facilitate the pushing of material from the full-fill forming chamber into the moving box, during process S5, after the moving box and the outlet end of the full-fill forming chamber are aligned, the clamping mechanism starts the clamping action. The third lifting mechanism and the second lifting mechanism simultaneously lift, raising the second gate and the gate at the feed end of the moving box to be fully open respectively. The extrusion cylinder continues to push the extrusion pusher forward, pushing the extruded material into the moving box until the pusher stops moving. When the extrusion pressure reaches 1.2 times f2, the extrusion cylinder retracts to its initial position. When the extrusion cylinder retracts, the extrusion pusher sequentially reaches the third position sensor, the second position sensor, and the first position sensor. The third lifting mechanism, the second lifting mechanism, and the first lifting mechanism then sequentially close the corresponding gates.

[0016] During S6, when the pusher pushes the material into the moving box, the extrusion pressure of the extrusion cylinder reaches 1.2 times f2 and stops at the full material level of the moving box, the current compression feeding process ends. The extrusion cylinder retracts, causing the pusher to return to its initial position, and then the gates are closed in sequence. The clamping device releases, and the moving box leaves.

[0017] The beneficial effects of the integrated compression method for kitchen waste of the present invention are as follows: by performing multiple pre-compression moldings on waste with high liquid content and temporarily storing it in a full-material molding hopper for preliminary compression molding, the waste liquid in the waste can be discharged, and the volume of the waste can be reduced, thereby increasing the amount of waste rotation; each time the full-material molding hopper is filled, material is pushed to the moving box and subjected to secondary compression and compaction, and the moving box is filled, thereby realizing the compression and drainage of kitchen waste with high liquid content. After compaction, the waste is sent to the moving box for waste rotation, which can increase the amount of waste transferred in a single trip and avoid leakage of material and liquid during waste transfer, which would cause secondary pollution to the environment and the site. At the same time, it reduces waste transfer costs and improves the efficiency of waste transfer and subsequent waste treatment. Attached Figure Description

[0021] The integrated compression method for kitchen waste in this embodiment specifically involves the following process: compressing and pushing the waste into the waste transfer container to fill it.

[0022] S1: Before starting, the first and second gates are closed, the pusher head is in the initial position on the left side of the feed inlet, the waste collection device pours the collected waste into the feed inlet of the extrusion chamber 4 through the receiving hopper 3, and fills the extrusion chamber 4 at the inlet end, and then enters the S2 process.

[0023] S2: The compression cylinder 1 pushes the compression pusher 2 to perform the first pre-compression and drainage of the waste in the compression chamber 4. The squeezed liquid is discharged through the drainage holes on the side and bottom. The pre-compression force of the compression cylinder 1 during this pre-compression is set to f1. The specific value of f1 is set according to the liquid content of the waste. Generally, multiple pressure levels of f1 are preset before leaving the factory. When the pre-compression force reaches f1 and the compression pusher 2 stops moving, this pre-compression is completed. At this point, the waste volume is reduced after compression and drainage, and the water content is greatly reduced. Then, proceed to S3.

[0024] S3: The pre-extruded material is pushed forward into the full-material forming chamber 7 for a second pre-extruded process. In this process, the first lifting mechanism 6 first lifts the first gate 5 to fully open. At this time, the extrusion chamber 4 and the full-material forming chamber 7 are fully connected. The extrusion cylinder 1 continues to drive the extrusion pusher 2 to push the pre-extruded material forward until the material is pushed against the second gate 9 and the extrusion pusher stops moving. When the extrusion pressure of the extrusion cylinder 1 reaches f2, and f2 > f1, generally f2 is 1.1-1.3 times f1. At this time, the material is pushed into the deepest part of the full-material forming chamber and compacted by the second extrusion. Then, when the extrusion cylinder 1 drives the extrusion pusher 2 to retreat to the position of the first position sensor 11, the first lifting mechanism 5 lowers the first gate 5 until it is fully closed. At the same time, the extrusion cylinder 1 continues to drive the extrusion pusher 2 back to the initial position and continues to receive material, repeating the process of S1 to S3, repeating receiving material, the first pre-extruded process, and the pushing material and the second pre-extruded process.

[0025] S4: The compression component resets and repeats the S1 to S3 process until the extrusion pusher 2 stops and reaches the f2 pushing force when the S3 process is repeated. At this time, if the position of the extrusion pusher 2 has not reached the first sensor, it is determined that the full material forming chamber is full and the process is switched to S5.

[0026] S5: The mobile box is connected to the discharge end of the full-material forming silo. The gates connecting the discharge end of the full-material forming silo and the feed end of the mobile box are opened. The compression component further squeezes and pushes the material in the discharge direction, pushing it into the mobile box. The material is then stacked and filled from the innermost end outwards within the mobile box. During this process, after the mobile box is properly connected to the discharge end of the full-material forming silo, the clamping mechanism starts its clamping action. The third lifting mechanism 10 and the second lifting mechanism 9 simultaneously lift, raising the second gate 8 and the gate at the feed end of the mobile box to full opening. When the extrusion cylinder 1 continues to push the extrusion pusher 2 forward, it pushes the material in the full forming chamber 7 into the moving box until the extrusion pusher 2 stops moving and the extrusion pressure reaches 1.2 times f2. Then, the extrusion cylinder 1 returns to its initial position. When the extrusion cylinder 1 returns, the extrusion pusher 2 sequentially reaches the third position sensor 13, the second position sensor 12 and the first position sensor 11. Then, the third lifting mechanism 10, the second lifting mechanism 9 and the first lifting mechanism 6 sequentially close the corresponding gate. When the extrusion pusher returns to its initial position, the process enters step S6.

[0027] S6: Repeat steps S1 to S5 until the moving box is filled with the compressed material. Then, the clamping device releases, and the moving box leaves. During this process, when the extrusion pusher 2 pushes the material into the moving box, the extrusion pressure of the extrusion cylinder 1 reaches 1.2 times f2, and the stopping position reaches the full material level of the moving box, the current compression and feeding process ends. The retraction action of the extrusion cylinder 1 drives the extrusion pusher 1 back to its initial position, and the gates are closed in sequence. The clamping device releases, and the moving box leaves, transferring the waste material away.

[0028] Kitchen waste or household waste with high moisture content, after being compressed by the above-mentioned integrated compression method, has a moisture content reduced by more than 90%, and the waste volume is reduced to less than 50%. This increases the amount of waste that can be rotated in a single batch and effectively avoids problems such as leakage and falling during waste transportation, reducing secondary pollution to the environment and the site. At the same time, it reduces waste transportation costs and improves the efficiency of waste transportation and subsequent waste treatment.
