Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment equipment, and more specifically, to a kitchen waste treatment device. Background Technology

[0002] Kitchen waste refers to the waste generated in daily life, food processing, catering services, and institutional catering activities. It includes discarded vegetable leaves, leftover food, fruit peels, eggshells, tea dregs, bones, etc. 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 or feed after strict treatment. It can also produce biogas for fuel or power generation. The oil portion can be used to prepare biofuel. During the treatment of kitchen waste, solid-liquid separation should be carried out as much as possible through treatment equipment to facilitate subsequent processing.

[0003] Patent application number 202323106303.5 discloses a kitchen waste treatment device, including a main body box, a squeezing box formed on top of the main body box, a squeezing chamber formed inside the squeezing box, and a U-shaped movable frame arranged inside the squeezing chamber. A first hydraulic cylinder with its head facing left is embedded in the right side plate of the movable frame, and a squeezing plate is fixed to the left end of the first hydraulic cylinder. Two second hydraulic cylinders symmetrically arranged vertically are embedded in the right side wall of the squeezing box, with their left ends extending into the squeezing box and fixedly connected to the right side of the movable frame. Several drainage holes are opened on the left side of the bottom wall of the squeezing box, and a rectangular discharge hole is opened on the right side of the bottom wall of the squeezing box. This utility model uses the extension and contraction of the first hydraulic cylinder to push the squeezing plate repeatedly closer to and further away from the left side plate of the movable frame, repeatedly squeezing the kitchen waste, causing the internal moisture of the kitchen waste to be discharged, reducing the moisture content, facilitating subsequent processing, and achieving good dehydration effect.

[0004] Regarding the aforementioned technologies, the first hydraulic cylinder extends and retracts to push the extrusion plate repeatedly towards and away from the left side plate of the movable frame, repeatedly extruding the kitchen waste to remove internal moisture and reduce its moisture content, thus facilitating subsequent processing. After the kitchen waste is extruded and dehydrated, it is moved to the top of the collection chamber, where it falls into the chamber, thus collecting the kitchen waste. This process is repeated. However, this invention requires multiple feedings for extrusion and dehydration, making continuous dehydration impossible and reducing the equipment's efficiency. Utility Model Content

[0005] To solve the above problems, this utility model provides a kitchen waste treatment device, which adopts the following technical solution:

[0006] A kitchen waste treatment device includes a frame with columns fixedly installed at the four corners of the bottom end of the frame. A cover plate is provided at the top of the frame and is fixed to the frame by bolts. A screening pipe is rotatably installed inside the frame, with both ends of the screening pipe penetrating the frame. Through holes matching the screening pipe are opened on both sides of the frame. A connecting cylinder and a discharge hopper are rotatably installed at both ends of the screening pipe. A stabilizing frame is fixedly installed on the side of the connecting cylinder and the discharge hopper opposite to the frame. A feeding frame is fixedly installed on the side wall of the connecting cylinder, and a crushing component is provided inside the feeding frame. A driving component is provided on the side wall of the screening pipe. An extrusion component is provided inside the connecting cylinder, the screening pipe, and the discharge hopper. A water storage tank is provided on one side of the frame, and a cleaning component is provided between the water storage tank and the frame. A drain pipe is connected to the bottom end of the frame.

[0007] By adopting the above technical solution, when using this equipment, workers transport kitchen waste into the feeding frame using existing conveying equipment. The feeding frame contains a crushing component to crush the kitchen waste, facilitating subsequent solid-liquid separation. The crushed kitchen waste enters the connecting cylinder through the feeding frame, and is then slowly conveyed into the screening tube by the extrusion component. The screening tube is driven to rotate at high speed by the drive component, centrifugally separating the liquid from the kitchen waste. The liquid remains inside the frame and is then discharged through the drain pipe. Existing filter screens and filters are installed in the holes on the surface of the screening tube. The cloth serves as a protective layer, helping to prevent debris from leaking out through the holes and maintaining the solid-liquid separation effect of the equipment. The side wall of the screening tube is equipped with a cleaning component, which generates a high-pressure airflow to blow onto the surface of the screening tube, achieving the effect of cleaning the holes in the screening tube. The cleaning component can also spray water to act on the side wall of the screening tube, achieving a further cleaning effect, which helps to maintain the solid-liquid separation effect of the equipment. The solid residue of kitchen waste can be conveyed through the extrusion component and discharged through the discharge hopper. Through the above structural combination, the equipment can process kitchen waste continuously, which helps to maintain the processing efficiency of the equipment.

[0008] Furthermore, the crushing assembly includes two rotating rods rotatably mounted inside the feed frame. Crushing rollers are fixedly sleeved on the sidewalls of both rotating rods. A second reduction motor is fixedly mounted on the side of the feed frame away from the frame body. The ends of the two rotating rods near the second reduction motors rotate through the feed frame. Drive gears are fixedly sleeved on the sidewalls of the ends of the two rotating rods that pass through the feed frame. The two drive gears are meshed. One of the rotating rods passes through the feed frame and is fixedly connected to the end of the output shaft of the second reduction motor.

[0009] By adopting the above technical solution, after the kitchen waste is put into the feeding frame, the rotating rod is driven to rotate by the second reduction motor. The two rotating rods are driven by a drive gear, so that the two rotating rods drive the crushing roller on the same side to rotate synchronously, thereby crushing the kitchen waste.

[0010] Furthermore, the drive assembly includes a secondary gear fixedly sleeved on the side wall of the screening tube near the connecting cylinder, a first geared motor fixedly installed on the top of the cover plate, and a main gear fixedly sleeved on the side wall of the output shaft of the first geared motor, with the main gear and the secondary gear meshing.

[0011] By adopting the above technical solution, when kitchen waste enters the screening tube, the main gear is driven to rotate by the first reduction motor, the main gear drives the secondary gear to rotate, and the secondary gear drives the screening tube to rotate at high speed with the kitchen waste, which can play the role of centrifugal screening of kitchen waste and achieve the effect of solid-liquid separation.

[0012] Furthermore, the extrusion assembly includes a support rod rotatably installed inside the screening tube, with both ends of the support rod extending into the connecting cylinder and the discharge hopper, respectively. A spiral blade is fixedly sleeved on the side wall of the support rod. An installation box is fixedly installed on the side of the connecting cylinder away from the frame. A third geared motor is fixedly installed inside the installation box. The end of the support rod away from the discharge hopper rotatably passes through the connecting cylinder and extends into the installation box. The end of the support rod passing through the connecting cylinder is fixedly connected to the end of the output shaft of the third geared motor.

[0013] By adopting the above technical solution, the support rod is driven to rotate by the third reduction motor, and the support rod drives the spiral blade to rotate synchronously. The spiral blade moves in the screening tube, which can play the role of conveying kitchen waste.

[0014] Furthermore, the cleaning assembly includes a water pump fixedly installed in the water storage tank. One end of the water pump is fixedly connected to a conduit. A multi-way connector is provided at the top of the cover plate. The branch pipes of the multi-way connector all penetrate the cover plate and are all connected to a connecting frame. A connecting pipe is fixedly installed at the end of the multi-way connector away from the connecting frame. A tee connector is connected between the connecting pipe and the conduit. A high-pressure air pump is provided at the top of the water storage tank. One end of the high-pressure air pump is connected to the end opposite to the tee connector. A first control valve is provided on the side wall of one end of the high-pressure air pump. A second control valve is provided on the side wall of the upper section of the conduit.

[0015] By adopting the above technical solution, the first control valve is opened and the second control valve is closed. A strong airflow generated by a high-pressure air pump enters the connecting pipe through the tee joint, and then enters the multi-way joint through the connecting pipe. Subsequently, the strong airflow is sprayed onto the surface of the screening pipe through the connecting frame, which cleans the holes in the screening pipe. Alternatively, the first control valve can be closed and the second control valve opened, and water from the storage tank can be drawn by a water pump. The water enters the multi-way joint through the conduit, tee joint, and connecting pipe, and is then sprayed onto the surface of the screening pipe through the connecting frame, thus cleaning the holes in the screening pipe. This helps maintain the screening efficiency of the equipment. The combination of the water pump and the high-pressure air pump allows the equipment to clean the screening pipe in multiple ways, which helps improve the performance of the equipment.

[0016] Furthermore, a blocking plate is provided on the side of the discharge hopper away from the frame. Two first support blocks are fixedly installed on the side wall of the blocking plate in a symmetrical arrangement. Two second support blocks are fixedly installed on the side wall of the discharge hopper away from the frame in a symmetrical arrangement. Each of the two first support blocks is provided with a screw on the side away from the frame. Each first support block has a through hole that matches the screw. Each second support block has a screw hole that matches the screw on the same side. Nuts are fitted on the side wall of each screw.

[0017] By adopting the above technical solution, a blocking plate is provided on the side of the discharge hopper away from the frame. The distance between the blocking plate and the discharge hopper can be adjusted by the cooperation of the screw and the second support block. When kitchen waste is discharged through the discharge hopper, it can be squeezed and formed by the action of the small gap between the blocking plate and the discharge hopper, which facilitates subsequent transportation. Nuts are sleeved on the side wall of the screw, which helps to maintain the stability of the blocking plate setting.

[0018] Furthermore, the inner wall of the frame is provided with two symmetrically distributed brush plates, both of which are in contact with the side wall of the screening tube, and the inner wall at the bottom of the frame is provided with two symmetrically distributed inclined blocks.

[0019] By adopting the above technical solution, a brush plate is provided inside the frame. The brush plate contacts the outside of the screening tube. When the screening tube rotates, the brush plate can clean the screening tube. Two symmetrically distributed inclined blocks are provided at the bottom of the frame to collect wastewater and facilitate the discharge of wastewater through the drain pipe.

[0020] Furthermore, four symmetrically distributed inserts are fixedly installed at the bottom of the cover plate, and slots matching the inserts are provided at the top of the frame.

[0021] By adopting the above technical solution, when installing the cover plate, the staff places the cover plate on the top of the frame, so that the insert block installed at the bottom of the cover plate engages with the slot opened at the top of the frame, which plays the role of positioning the cover plate and facilitating subsequent fixing. The cover plate and the frame are set separately, which makes it easy for the staff to disassemble the cover plate and clean or repair the internal structure of the frame.

[0022] In summary, this utility model has the following beneficial technical effects:

[0023] (1) In this utility model, the crushing component is set to crush kitchen waste. The crushed kitchen waste enters the connecting cylinder and is then placed into the screening tube by the extrusion component. The screening tube is driven to rotate at high speed by the drive component, which can centrifuge the kitchen waste and achieve solid-liquid separation. The centrifuged kitchen waste is transported to the discharge hopper by the extrusion component. With the cooperation of the above structure, the equipment can process kitchen waste continuously, which is conducive to improving the processing efficiency of the equipment.

[0024] (2) In this utility model, the screen is provided with a filter screen of the prior art inside the screen tube hole, which helps to prevent the crushed residue from leaking out through the hole. The side wall of the screen tube is provided with a brush plate. When the screen tube rotates, the brush plate can clean the screen tube hole. In addition, through the setting of the cleaning component, the high pressure airflow is sprayed to the surface of the screen tube through the cleaning component, which can further clean the screen tube hole. Subsequently, water can be discharged to the surface of the screen tube through the cleaning component to achieve the cleaning effect.

[0025] (3) In this utility model, a blocking plate is provided at the end of the discharge hopper. Through the cooperation of the screw and the second support block, the distance between the blocking plate and the discharge hopper can be adjusted.
