Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] See attached document Figures 1-4 This utility model provides a solid-liquid separation cleaning machine, including a conveyor belt frame 100. The conveyor belt frame 100 serves as the basic support structure for material conveying. Support frames are fixed to the front and rear sides of its outer wall to ensure the frame remains stable during operation and prevent displacement due to material weight or equipment vibration. A material conveyor belt 110 is installed on the conveyor belt frame 100 to transport the material to be separated from the solid-liquid mixture. The material conveyor belt 110 is mounted on the conveyor belt frame 100, and its core function is to transport the material to be separated from the solid-liquid mixture (such as liquid-containing solid waste, sewage mixture, etc.). Drainage holes are provided on the surface of the conveyor belt to initially separate some of the free liquid in the material during conveying. Both ends of the material conveyor belt 110 can be connected to the conveyor belt mechanism via rotating rollers. The frame 100 is connected to the outer wall of the conveyor belt frame 100. Support frames for support are fixed on the front and rear sides of the outer wall of the material conveyor belt 110. A retrieval frame 120 for retrieving materials is fixed on the outer wall side of the material conveyor belt (110). The retrieval frames 120 are fixed on the outer wall side of the material conveyor belt (110) and are distributed in an intermittent manner. They are used to "retrieve" materials during the material conveying process to prevent materials from slipping when the conveyor belt is tilted and to ensure that the materials move stably towards the solid-liquid separator (200). A drive motor 130 for driving the material conveyor belt 110 to rotate is installed on the outer wall side of the conveyor belt frame 100. The drive motor 130 is connected to the rotating roller of the material conveyor belt 110. By driving the rotating roller to rotate, the material conveyor belt 110 is driven to achieve cyclic movement, providing power for material conveying.

[0023] A solid-liquid separator 200 for solid-liquid separation of materials is installed on one side of the outer wall of the conveyor frame 100. The solid-liquid separator 200 contains a solid-liquid separation mechanism, which includes two extrusion rollers 230. The front and rear ends of both extrusion rollers 230 are rotatably connected to the front and rear sides of the inner wall of the solid-liquid separator 200 via bearing seats. A servo motor is fixed at the rear end of the outer wall of the solid-liquid separator 200, corresponding to the position of the extrusion rollers 230, to drive the two extrusion rollers 230 to rotate relative to each other. One set of servo motors can be installed. A gear set is rotatably connected at the front end of the outer wall of the solid-liquid separator 200, corresponding to the position of the two extrusion rollers 230. The gear set enables the other extrusion roller 230 to rotate together when one extrusion roller 230 rotates. A material gathering plate 2 is fixed at the inner wall side of the solid-liquid separator 200, above the extrusion rollers 230. 20, while the material gathering plate 220 is designed with an inclination. Its function is to gather the material conveyed by the guide plate 210 between the two extrusion rollers 230, so as to avoid the material from scattering and ensure the extrusion separation efficiency. The top of the outer wall of the solid-liquid separator 200 and below the top of the conveyor belt frame 100 is provided with a guide plate 210 for guiding the flow. The guide plate 210 is set above the top of the outer wall of the material gathering plate 220. The guide plate 210 is used to receive the material falling from the top of the material conveyor belt 110 and guide the material to the material gathering plate 220, playing a "bridge-like" guiding role. On both sides of the inner wall of the solid-liquid separator 200 and below the extrusion rollers 230, scrapers 231 for preventing material from sticking are provided. The top of the scraper 231 makes slight contact with the outer wall of the extrusion rollers 230, which can clean the solid material adhering to the surface of the extrusion rollers 230 in real time during the rotation of the extrusion rollers 230, preventing the blockage problem caused by material adhesion.

[0024] A flow divider 240 is fixed to the inner wall side of the solid-liquid separator 200, below the extrusion roller 230. The flow divider 240 is arranged with the left side higher than the right side. The surface of the flow divider 240 has through holes. Its functions are: first, to receive the liquid dripping from the extrusion roller 230 and guide the liquid to the first liquid storage tank 241 below through the through holes; and second, to guide the extruded solid material to the designated second liquid storage tank 320. A set of vibrators can be fixed to the bottom of the outer wall of the flow divider 240 as needed to improve the vibration effect of the flow divider 240. To prevent solid waste from accumulating on the diversion plate 240, a first liquid storage tank 241 is provided at the bottom of the inner wall of the solid-liquid separator 200, below the diversion plate 240. This first liquid storage tank 241 stores the liquid that drips through the through-holes of the diversion plate 240 and is separated by compression. The first liquid storage tank 241 can be extracted from the outlet at the front end of the solid-liquid separator 200 for easy subsequent liquid cleaning and treatment. A second liquid storage tank 320 is provided at the bottom of the inner wall of the solid-liquid separator 200, to one side of the first liquid storage tank 241. One end of the solid-liquid separator 200 extends to the top of the outer wall of the second liquid storage tank 320. A hydraulic rod 300 is fixed at the top of the outer wall of the solid-liquid separator 200 and above the second liquid storage tank 320. The hydraulic rod 300 is powered by a hydraulic cylinder and pump at the rear end, which can drive the pressure plate 310 to move up and down. The bottom output end of the hydraulic rod 300 passes through the top of the inner wall of the solid-liquid separator 200 and is fixed with the pressure plate 310 for pressing the material. The pressure plate 310 can extend into or out of the second liquid storage tank 320 with the movement of the hydraulic rod 300. The second liquid storage tank 320 is used to perform secondary compression on the solid material in the second liquid storage tank 320 to further remove residual liquid from the material. The inner wall side of the second liquid storage tank 320 is fixed with a separation plate 321 for separation. The surface of the separation plate 321 is provided with water filtering holes. When the pressure plate 310 performs secondary compression, the liquid squeezed out of the material can pass through the water filtering holes and fall into the bottom of the second liquid storage tank 320, realizing the further separation of solid and liquid. The second liquid storage tank 320 can be pulled out from the material outlet on the outer wall side of the solid-liquid separator 200, which is convenient for cleaning solid material and residual liquid.

[0025] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. The control programs of all electrical equipment are edited by the production personnel in advance before production. This utility model does not make any technical improvements here, but only assumes that it can normally meet the needs of personnel.

[0026] According to the component connection relationship of the above technical solution, complete the overall assembly of the solid-liquid separation cleaning machine: fix the conveyor belt frame 100 to the horizontal working ground through the support frames on its front and rear sides to ensure that the frame is not tilted or swaying; install the solid-liquid separator 200 on one side of the outer wall of the conveyor belt frame 100, and adjust its position so that the guide plate 210 can accurately receive the material falling from the top of the material conveyor belt 110; place the first liquid storage tank 241 and the second liquid storage tank 320 into the corresponding positions at the bottom of the inner wall of the solid-liquid separator 200, and fix the two liquid storage tanks with bolts or other fasteners to prevent the equipment from shifting during operation;

[0027] All electrical components of the equipment, including drive motor 130, servo motor, hydraulic cylinder and oil pump matched with hydraulic rod 300, are connected to external power supply, and each component is electrically connected to external controller. The control program for all electrical components of the equipment has been preset in the production stage to ensure that the operation requirements are met during operation.

[0028] Check the status of each component of the equipment: confirm that the material conveyor belt 110 runs smoothly, the extrusion roller 230 rotates without jamming, the scraper 231 is in close contact with the extrusion roller 230, the hydraulic rod 300 drives the pressure plate 310 to rise and fall flexibly, and the liquid storage tank is firmly fixed. At the same time, check through the glass window at the rear end of the solid-liquid separator 200 to confirm that there are no foreign objects inside the liquid storage tank, and ensure that the equipment can start normally.

[0029] The operator places the materials to be separated into solid and liquid, such as liquid solid waste and sewage mixture, evenly on the material conveyor belt 110 and starts the drive motor 130 through an external controller.

[0030] The drive motor 130 drives the rollers of the material conveyor belt 110 to rotate, causing the material conveyor belt 110 to circulate. The retrieval frame 120 on the outer wall of the material conveyor belt 110 stably lifts the material and conveys it towards the solid-liquid separator 200. During the conveying process, some of the free liquid in the material drips naturally through the drain holes on the surface of the material conveyor belt 110, achieving preliminary solid-liquid separation. The dripping liquid can be collected and treated through a pre-set liquid receiving tank.

[0031] Three-stage extrusion separation

[0032] After the material is conveyed to the top by the material conveyor belt 110, it falls onto the guide plate 210 at the top of the solid-liquid separator 200 under the action of gravity. The guide plate 210 guides the material to the material gathering plate 220, which further gathers the material and guides it between the two extrusion rollers 230.

[0033] The servo motor is started by an external controller. The servo motor drives the two extrusion rollers 230 to rotate in opposite directions through the transmission gear. After the material falls between the two extrusion rollers 230, it is continuously squeezed by the rotating extrusion rollers 230. The liquid in the material is squeezed out and drips from between the two extrusion rollers 230 onto the diverter plate 240 below.

[0034] The through holes on the surface of the diverter plate 240 filter the dripping liquid, which then falls through the through holes into the first liquid storage tank 241 below for storage. The extruded solid material remains on the diverter plate 240 and, guided by the inclined structure of the diverter plate 240 (higher on the left and lower on the right), slides into the second liquid storage tank 320. At the same time, the scrapers 231 on both sides of the extrusion roller 230 clean the material adhering to the surface of the extrusion roller 230 in real time to prevent material from adhering and clogging.

[0035] Four-stage extrusion separation

[0036] The operator observes the accumulation of solid material in the second storage tank 320 through the glass window at the rear of the solid-liquid separator 200. When the material accumulates to a preset height, which is usually 2 / 3 of the volume of the second storage tank 320, the operator shuts down the drive motor 130 and the servo motor through the controller to stop the material conveying and the first-stage extrusion.

[0037] The hydraulic cylinder and pump associated with the hydraulic rod 300 are activated. Under pressure, the hydraulic rod 300 pushes the pressure plate 310 downward. The pressure plate 310 extends into the second liquid storage tank 320 and performs secondary compression on the solid material in the tank. During the compression process, the residual liquid in the material is squeezed out and falls into the bottom of the second liquid storage tank 320 for storage through the filter holes of the separation plate 321 inside the second liquid storage tank 320.

[0038] The secondary extrusion continues for a preset time, which is adjusted according to the moisture content of the material. Usually, it is 1-3 minutes. After that, the hydraulic cylinder is depressurized by the controller, and the hydraulic rod 300 drives the pressure plate 310 to move upward and reset to the top inner wall of the solid-liquid separator 200, thus completing the secondary extrusion.

[0039] 5. Material and Liquid Cleaning

[0040] Open the discharge port at the front end of the solid-liquid separator 200, loosen the fasteners of the first liquid storage tank 241, pull out the first liquid storage tank 241, perform subsequent processing such as filtration and purification on the primary separated liquid stored in the tank, and after cleaning, put the first liquid storage tank 241 back in place and fix it again.

[0041] Open the material inlet on the outer side of the solid-liquid separator 200, loosen the fasteners of the second liquid storage tank 320, and pull out the second liquid storage tank 320. Clean the solid material and the secondary separation liquid stored at the bottom of the tank separately. The solid material can be recycled or disposed of later, while the liquid is combined with the primary separation liquid for treatment. After cleaning, put the second liquid storage tank 320 back in place and fix it again.

[0042] After cleaning, start the equipment under no-load for 1-2 minutes using the controller to check whether each component has returned to normal. Once confirmed to be in good condition, the equipment can proceed to the next round of solid-liquid separation.

[0043] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above.
