[0002] Dehydration by squeezing kitchen waste is an important step in the kitchen waste treatment process. Its main purpose is to separate the water and organic matter from the kitchen waste through mechanical squeezing, so as to achieve waste reduction, resource recovery and harmless treatment.

[0003] Chinese patent CN222309932U discloses a kitchen waste squeezing and dehydration device for convenient discharge. The device uses hydraulic cylinders on both sides to drive piston blocks to squeeze the waste and achieve dehydration. After dehydration, the piston block on one side moves to one end, while the other piston slider pushes the waste to move so that it can be accurately discharged through the discharge hole. However, this device only filters the water generated during the squeezing of kitchen waste through the water outlet at the bottom of the shell, resulting in a slow squeezing and dehydration efficiency of kitchen waste.

The two movable lead screws are respectively located on both sides of the extrusion cylinder, and the machine body is provided with a synchronization mechanism for driving the two movable lead screws to rotate synchronously.

[0007] A further feature of this invention is that the synchronization mechanism includes a rotating wheel disposed at the end of the movable lead screw and a synchronization belt disposed between the two rotating wheels, and the machine body is provided with a drive motor for driving one of the movable lead screws to rotate.

[0008] A further feature of this invention is that: guide rods are symmetrically arranged on the machine body along the horizontal direction, one end of the guide rod is fixedly connected to the fixed plate, and guide blocks are symmetrically arranged on both sides of the extrusion cylinder, with the guide rods moving through the guide blocks.

[0009] A further feature of this invention is that a synchronization block is provided at the bottom of the guide block, and the synchronization block is fixedly connected to the second guide plate. When one end of the extrusion cylinder abuts against the fixed plate, one end of the second guide plate abuts against the fixed plate.

[0010] A further feature of this invention is that both the first guide plate and the second guide plate are inclined, and the horizontal plane of the end of the first guide plate near the fixed plate is higher than the horizontal plane of the end of the first guide plate away from the fixed plate.

[0011] A further feature of this invention is that a third guide plate is inclinedly provided at the end of the machine body away from the fixed plate, and a liquid outlet is formed between the end of the third guide plate near the fixed plate and the end of the first guide plate away from the fixed plate, and the liquid receiving frame is located directly below the liquid outlet.

[0012] A further feature of this invention is that baffles are symmetrically arranged on both sides of the machine body, and a moving wheel is rotatably arranged at the bottom end of the moving block, with the bottom end of the moving wheel abutting against the top end of the baffle.

[0013] A further feature of this invention is that the top of the baffle is provided with an elongated moving groove that cooperates with the moving wheel, and the bottom end of the moving wheel abuts against the moving groove.

[0014] A further feature of this invention is that a cleaning mechanism for cleaning the second cylinder is provided at one end of the baffle near the fixed plate. The cleaning mechanism includes a long strip cleaning pipe disposed on the top of the baffle and a plurality of nozzles obliquely downward connected to the cleaning pipe. A water pump connected to the cleaning pipe is provided on the baffle.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting up a first cylinder, a second cylinder, and a first guide plate, when it is necessary to squeeze and dehydrate kitchen waste, the squeezing cylinder is first moved to contact the fixed plate by a moving mechanism, while the second guide plate is pushed to contact the fixed plate. At this time, the squeezing plate is movably attached to the inner wall of the first cylinder away from the fixed plate. Then, kitchen waste is added from the feed hopper, the squeezing cylinder is opened, and the squeezing cylinder drives the squeezing plate to move in the direction close to the fixed plate. During this process, the squeezing plate pushes the kitchen waste in the first cylinder into the second cylinder until the kitchen waste contacts the fixed plate. Then, under the limitation of the fixed plate and the squeezing of the squeezing plate, the water in the kitchen waste is discharged from the filter holes on the outer wall of the second cylinder and drips onto the second guide plate. The water flows along the second guide plate to the first guide plate and finally drips from the edge of the first guide plate into the liquid receiving frame below. After the kitchen waste is squeezed and dehydrated, the moving mechanism is opened to drive the squeezing cylinder to move away from the fixed plate, while pushing the second guide plate away from the fixed plate. The discharge port between the fixed plate and the first guide plate is opened. When the extrusion cylinder moves away from the fixed plate to a certain distance, the extruded kitchen waste remains stationary under the limitation of the extrusion plate and the fixed plate. At this time, the extrusion cylinder is opened, driving the extrusion plate to move away from the fixed plate. The extruded kitchen waste will fall under the action of gravity and fall from the discharge port into the receiving frame below, thus realizing the entire process of extruding and dehydrating kitchen waste. By setting up a first cylinder and a second cylinder, the kitchen waste is fed from the first cylinder. After the added kitchen waste enters the second cylinder under the push of the extrusion plate, the water will be filtered through the filter holes on the outer wall of the second cylinder. During the process of the extrusion plate extruding the kitchen waste, the water will also be filtered through the filter holes around the second cylinder. Therefore, by setting up a second cylinder with filter holes evenly opened on the outer wall, the area on which the kitchen waste can be filtered is greatly increased, thereby improving the extrusion and dehydration efficiency of the kitchen waste. At the same time, a moving mechanism is set up to drive the extrusion cylinder to move, which facilitates the unloading of the extruded and dehydrated kitchen waste.

[0017] 2. By setting guide rods, guide blocks, and synchronization blocks, the guide rods and guide blocks can guide the movement direction of the extrusion cylinder and also share the weight of the extrusion cylinder, making the extrusion cylinder more stable during movement; the synchronization block can connect the extrusion cylinder to the second guide plate, so that the extrusion cylinder moves synchronously with the second guide plate during movement, realizing the automatic opening and closing of the discharge port, which facilitates the separate collection of water and organic matter in kitchen waste, eliminating the need for workers to manually push the second guide plate, making the operation more convenient.

[0018] 3. Through the baffle and the moving wheel, the weight of the extrusion cylinder can be applied to the baffle through the moving wheel. During the process of driving the extrusion cylinder to move, there is rolling friction between the extrusion cylinder and the baffle, which greatly reduces the friction force that needs to be overcome during the movement of the extrusion cylinder, making the movement of the extrusion cylinder more stable and extending the service life of the equipment.

[0019] 4. By setting up nozzles and cleaning pipes, after the kitchen waste is squeezed and dehydrated, the nozzles can be turned on. The nozzles set at an angle downward on both sides of the baffle can rinse the outer wall of the second cylinder, removing solid matter from the outer wall of the second cylinder and the filter holes, thereby preventing solid matter from clogging the filter holes and ensuring the efficiency of subsequent squeezing and dehydration of kitchen waste.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] This utility model provides a kitchen waste dehydration and compression device, such as... Figures 1 to 6 As shown, the machine includes a body 1, an extrusion cylinder 2 with openings at both ends that is movably mounted on the body 1 in a horizontal direction, and an extrusion cylinder 3 that is horizontally mounted on the body 1. The extrusion cylinder 2 includes a first cylinder 2a and a second cylinder 2b. A feed hopper 4 is connected to the top of the first cylinder 2a. Filter holes 5 are evenly distributed on the outer wall of the second cylinder 2b. An extrusion plate 6 that is movably attached to the inner wall of the extrusion cylinder 2 is vertically mounted at the output end of the extrusion cylinder 3. A fixing plate 7 is vertically mounted at the end of the body 1 away from the extrusion cylinder 3. The bottom of the body 1... The machine body 1 is provided with a first guide plate 8, which is at a set distance from the fixed plate 7. A second guide plate 9 is slidably disposed on the first guide plate 8, and the second guide plate 9 can abut against the side of the fixed plate 7 near the extrusion cylinder 2. A liquid receiving frame 10 and a material receiving frame 11 are movably disposed at the bottom of the machine body 1. An outlet 12 is formed between the first guide plate 8 and the fixed plate 7. The material receiving frame 11 is located directly below the outlet 12. The machine body 1 is provided with a moving mechanism 13 for driving the extrusion cylinder 2 to move in the horizontal direction.

[0030] Furthermore, the moving mechanism 13 includes a moving lead screw 13a symmetrically rotated on the machine body 1 in the horizontal direction and a moving block 13b cooperating on the moving lead screw 13a. One end of the moving lead screw 13a is rotatably connected to the fixed plate 7, and the moving block 13b is fixedly connected to the outer wall of the extrusion cylinder 2. The two moving lead screws 13a are respectively located on both sides of the extrusion cylinder 2. The machine body 1 is provided with a synchronization mechanism 14 for driving the two moving lead screws 13a to rotate synchronously.

[0031] Furthermore, the synchronization mechanism 14 includes a rotating wheel 14a disposed at the end of the moving lead screw 13a and a timing belt 14b disposed between the two rotating wheels 14a, and a drive motor 15 for driving one of the moving lead screws 13a to rotate is disposed on the machine body 1.

[0032] Furthermore, guide rods 16 are symmetrically arranged on the machine body 1 along the horizontal direction. One end of the guide rod 16 is fixedly connected to the fixed plate 7. Guide blocks 17 are symmetrically arranged on both sides of the extrusion cylinder 3. The guide rod 16 moves through the guide block 17.

[0033] Furthermore, a synchronization block 18 is provided at the bottom of the guide block 17. The synchronization block 18 is fixedly connected to the second guide plate 9. When one end of the extrusion cylinder 2 abuts against the fixed plate 7, one end of the second guide plate 9 abuts against the fixed plate 7.

[0034] Furthermore, both the first guide plate 8 and the second guide plate 9 are inclined, and the horizontal plane of the end of the first guide plate 8 near the fixed plate 7 is higher than the horizontal plane of the end of the first guide plate 8 away from the fixed plate 7.

[0035] Furthermore, a third guide plate 19 is inclinedly provided at the end of the machine body 1 away from the fixed plate 7. A liquid outlet 20 is formed between the end of the third guide plate 19 near the fixed plate 7 and the end of the first guide plate 8 away from the fixed plate 7. The liquid receiving frame 10 is located directly below the liquid outlet 20.

[0036] Furthermore, baffles 21 are symmetrically arranged on both sides of the body 1, and a moving wheel 22 is rotatably arranged at the bottom end of the moving block 13b, with the bottom end of the moving wheel 22 abutting against the top end of the baffle 21.

[0037] Furthermore, the top of the baffle 21 is provided with an elongated moving groove 23 that cooperates with the moving wheel 22, and the bottom end of the moving wheel 22 abuts against the moving groove 23.

[0038] Furthermore, a cleaning mechanism 24 for cleaning the second cylinder 2b is provided at one end of the baffle 21 near the fixed plate 7. The cleaning mechanism 24 includes a long strip cleaning pipe 24a disposed at the top of the baffle 21 and a plurality of nozzles 24b obliquely downward connected to the cleaning pipe 24a. A water pump 25 connected to the cleaning pipe 24a is provided on the baffle 21.

[0039] When kitchen waste needs to be squeezed and dehydrated, the drive motor 15 first drives the two moving screws 13a to rotate via the synchronous belt 14b, thereby driving the moving block 13b to move the squeezing cylinder 2 to contact the fixed plate 7. During this process, the squeezing cylinder 2 drives the second guide plate 9 to contact the fixed plate 7 via the synchronous block 18. At this time, the squeezing plate 6 is movably attached to the inner wall of the first cylinder 2a away from the fixed plate 7. Then, kitchen waste is added from the feed hopper 4, the squeezing cylinder 3 is opened, and the squeezing cylinder 3 drives the squeezing plate 6 to move in the direction close to the fixed plate 7. During this process, the squeezing plate 6... The kitchen waste in the first cylinder 2a is pushed into the second cylinder 2b until it comes into contact with the fixed plate 7. Then, under the limiting effect of the fixed plate 7 and the squeezing effect of the squeezing plate 6, the water in the kitchen waste is discharged from the filter holes 5 on the outer wall of the second cylinder 2b and drips onto the second guide plate 9. The water flows along the inclined second guide plate 9 to the first guide plate 8, and finally drips from the liquid outlet 20 between the first guide plate 8 and the third guide plate 19 into the liquid receiving frame 10 below. After the kitchen waste is squeezed and dehydrated, the drive motor 15 is turned on, and the squeezing cylinder 2 is driven to move away from the fixed plate 7. Simultaneously, the extrusion cylinder 2 moves the second guide plate 9 away from the fixed plate 7, causing the discharge port 12 between the fixed plate 7 and the first guide plate 8 to open. When the extrusion cylinder 2 moves away from the fixed plate 7 to a certain distance, the extruded kitchen waste remains stationary under the constraint of the extrusion plate 6 and the fixed plate 7. At this time, the extrusion cylinder 3 is opened, driving the extrusion plate 6 to move away from the fixed plate 7. The extruded kitchen waste will then fall under the action of gravity and drop from the discharge port 12 into the receiving frame 11 below, thus realizing the entire process of extruding and dehydrating kitchen waste. By setting the first cylinder 2a and the second cylinder 2b, from The first cylinder 2a is used for feeding. The added kitchen waste is pushed into the second cylinder 2b by the extrusion plate 6. The water will be filtered through the filter holes 5 on the outer wall of the second cylinder 2b. During the extrusion process of the extrusion plate 6, the water will also be filtered through the filter holes 5 around the second cylinder 2b. Therefore, by setting the second cylinder 2b with filter holes 5 evenly opened on the outer wall, the area where kitchen waste can be filtered is greatly increased, thereby improving the extrusion and dehydration efficiency of kitchen waste. At the same time, a moving mechanism 13 is set to drive the extrusion cylinder 2 to move, which facilitates the feeding of the extruded and dehydrated kitchen waste.

[0040] By setting up movable lead screws 13a, movable blocks 13b, etc., when it is necessary to drive the extrusion cylinder 2 to move, the drive motor 15 is turned on, and the two rotating wheels 14a are driven to rotate through the synchronous belt 14b, which in turn drives the two movable lead screws 13a to rotate synchronously, thereby driving the movable blocks 13b and the extrusion cylinder 2 to move along the movable lead screws 13a. The structure is simple and the operation is convenient.

[0041] By setting guide rod 16, guide block 17 and synchronization block 18, guide rod 16 and guide block 17 can guide the movement direction of extrusion cylinder 2 and also share the weight of extrusion cylinder 2, making extrusion cylinder 2 more stable during movement; synchronization block 18 can connect extrusion cylinder 2 to second guide plate 9, so that extrusion cylinder 2 drives second guide plate 9 to move synchronously during movement, realizing automatic opening and closing of discharge port 12, which facilitates the separate collection of water and organic matter in kitchen waste, and eliminates the need for workers to manually push second guide plate 9, making operation more convenient.

[0042] By tilting the first guide plate 8 and the second guide plate 9, the water passing through the second cylinder 2b can drip from the liquid outlet 20 into the liquid receiving frame 10 along the second guide plate 9 and the first guide plate 8, thus preventing water from accumulating in the second guide plate 9 and affecting the surrounding environment.

[0043] Through the baffle 21 and the moving wheel 22, the gravity of the extrusion cylinder 2 can be applied to the baffle 21 through the moving wheel 22. During the process of driving the extrusion cylinder 2 to move, there is rolling friction between the extrusion cylinder 2 and the baffle 21, which greatly reduces the friction force that needs to be overcome during the movement of the extrusion cylinder 2, making the movement of the extrusion cylinder 2 more stable and extending the service life of the equipment.

[0044] By setting the moving groove 23, on the one hand, the moving wheel 22 is limited, making the movement of the moving wheel 22 more stable. On the other hand, the movable distance of the moving wheel 22 is limited, thereby limiting the moving distance of the extrusion cylinder 2 and ensuring the orderly progress of the entire process.

[0045] By setting up nozzle 24b and cleaning pipe 24a, after the kitchen waste is squeezed and dehydrated, nozzle 24b can be opened. The nozzles 24b, which are set diagonally downward on both sides of baffle 21, can rinse the outer wall of the second cylinder 2b to remove solid matter from the outer wall of the second cylinder 2b and the filter hole 5, thereby preventing solid matter from clogging the filter hole 5 and ensuring the efficiency of subsequent squeezing and dehydration of kitchen waste.

[0046] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0047] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
