The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] The following is for reference. Figures 1-4 The implementation of the organic waste treatment system proposed in the embodiments of this utility model will be described in detail.

[0034] The organic waste treatment system according to an embodiment of the present invention includes: a pulping machine 1, a coarse pulp tank 2, an integrated impurity removal machine 3, a good pulp tank 4, a light slag dewatering machine 5, and a heavy slag separator 6.

[0035] Specifically, the pulper 1 is suitable for pulping organic waste and separating light slag; the coarse slurry tank 2 is connected to the pulper 1 to receive the slurry pumped from the pulper 1 and to filter and remove impurities from the slurry; the integrated impurity removal machine 3 has a tank 301 and an agitator 302. The tank 301 is provided with an inlet 303, an outlet 304, a heavy slag outlet 305, and a light slag outlet 306. The inlet 303 is connected to the coarse slurry tank 2 so that the slurry is pumped into the tank 301. The agitator 302 is suitable for stirring and breaking up the slurry in the tank 301 so that the slurry rotates and separates the heavy slag and light slag. The heavy slag outlet 305 is set away from the rotation center of the agitator 302 to collect the heavy slag in the slurry. The light slag outlet 306 is set close to the rotation center of the agitator 302 to collect the light slag in the slurry. The outlet 304... A first screen plate 307 is provided; a good pulp tank 4 is connected to a discharge port 304 to receive the good pulp passing through the first screen plate 307 and discharge the good pulp from the good pulp outlet 41; a light slag dewatering machine 5 is connected to a pulping machine 1 and a light slag outlet 306 to receive the light slag discharged from the pulping machine 1 and the integrated impurity removal machine 3, and to perform rotary dewatering on the received light slag; the light slag dewatering machine 5 is connected to a coarse pulp tank 2 to transport the pulp from which the light slag has been separated to the coarse pulp tank 2; a heavy slag separator 6 has a heavy slag tank 601 and a separation device 602; the heavy slag tank 601 is connected to a heavy slag outlet 305 to receive the heavy slag discharged from the integrated impurity removal machine 3, and to rotary discharge the heavy slag into the separation device 602; the separation device 602 is suitable for solid-liquid separation of the heavy slag; the separation device 602 is connected to the integrated impurity removal machine to transport the separated pulp to the tank 301.

[0036] In other words, raw kitchen waste and food scraps are fed into pulping machine 1 for crushing and refining to make pulp. The pulp is pumped through the screen plate in pulping machine 1 to coarse pulp tank 2, while the uncrushed light slag is discharged to light slag dewatering machine 5. After filtering and removing impurities in coarse pulp tank 2, the pulp is pumped from the feed inlet 303 of the impurity removal machine 3 to tank 301. The stirring element 302 in tank 301 rotates to stir and crush the pulp. Under the action of centrifugal force, light slag and heavy slag are separated from the pulp. The lighter light slag moves to the light slag outlet 306, which is closer to the stirring element 302, and is discharged into light slag dewatering machine 5 for dewatering. The slurry is returned to the coarse slurry tank 2, while the light slag is discharged from the outlet of the light slag dewatering machine 5. The heavier slag, under the action of centrifugal force, moves to the heavy slag outlet 305, which is farther away from the agitator 302, and is discharged into the heavy slag tank 601 of the heavy slag separator 6. The heavy slag tank 601 rotates to smoothly discharge the heavy slag into the separation device 602. The separation device 602 performs solid-liquid separation on the heavy slag and discharges the heavy slag. The separated slurry is returned to the coarse slurry tank 2. The remaining slurry in the tank 301 is pumped through the first screen plate 307 of the discharge port 304 and pumped into the good slurry tank 4 under the action of pumping force. The good slurry tank 4 then discharges the good slurry from the good slurry outlet 41. The pulper 1 can break down and refine organic waste through rotating blades, and the light slag in the pulper 1 can be discharged into the light slag dewatering machine 5 through a pipe; the coarse pulp tank 2 can be cleaned by using a screen plate in the coarse pulp tank 2, or it can be filtered and cleaned by a cleaning pump installed on the pipe between the coarse pulp tank 2 and the cleaning integrated machine 3.

[0037] Thus, kitchen waste enters the pulping machine 1 for initial crushing and refining, separating slurry and light slag. The slurry is pumped to the coarse slurry tank 2, where it is then pumped to the impurity removal machine 3 after impurity removal. In the impurity removal machine 3, the slurry undergoes secondary crushing and refining, separating heavy slag and light slag. The refined slurry is discharged into the good slurry tank 4 through the first screen plate 307 of the impurity removal machine 3. The good slurry is then discharged from the good slurry tank 4. The light slag is discharged through the light slag outlet 306 to the light slag dewatering machine 5 for solid-liquid separation. The separated slurry is returned to the coarse slurry tank 2. The heavy slag is discharged through the heavy slag outlet 305 into the heavy slag separator 6 for solid-liquid separation. The separated slurry is returned to the coarse slurry tank 2. This process greatly reduces the amount of equipment required, shortens the process flow, and ensures excellent impurity removal of the slurry.

[0038] Optionally, the inlet of the external pipe of the feed inlet 303, the outlet of the external pipe of the good slurry inlet 41, and the outlet of the external pipe of the light slag inlet 306 are all set higher than the tank body 301, and the external pipes of the good slurry inlet 41 and the light slag inlet 306 are all equipped with valves that can adjust the flow rate. Understandably, the above setup facilitates the formation of a pressure difference between the feed inlet 303 and the good slurry inlet 41, and between the feed inlet 303 and the light slag inlet 306. By adjusting the opening and closing degree of the valves on the external pipes of the good slurry inlet 41 and the light slag inlet 306, the flow rate of the pipes can be adjusted, thereby adjusting the pressure inside the tank 301. This ensures the smooth rotation of the slurry inside the tank 301 and improves the separation efficiency of light slag, heavy slag, and good slurry. Both the external pipes of the feed inlet 303 and the good slurry inlet 41 are equipped with pressure detection devices 7 to detect the pressure inside the pipes, making it easy to observe the pressure in the external pipes of the feed inlet 303 and the good slurry inlet 41, thus facilitating the protection of the overall device operation. The pressure detection device 7 can be a pressure sensor or a pressure gauge.

[0039] Furthermore, the tank 301 is cylindrical, with one outer end of the tank 301 positioned along the inner first screen plate 308. A light slag outlet 306 is located at the first screen plate 308. Understandably, the cylindrical shape of the tank 301 and the placement of the first screen plate 308 facilitate better coordination with the rotation of the agitator 302, enabling the slurry to rapidly rotate and separate heavy and light slag. The placement of the light slag outlet 306 at the first screen plate 308 increases the contact area between the first screen plate 308 and the light slag, thus facilitating the collection and discharge of the light slag and guiding it to the outlet 306. The agitator 302 may extend from the opposite end of the first screen plate 308 towards the first screen plate 308, and the agitator 302 is equipped with blades.

[0040] Furthermore, the light slag inlet 306 is located at the center of the first screen plate 308, and the heavy slag inlet 305 is located at the tangent of the outer circular surface of the tank body 301. Understandably, by placing the light slag inlet 306 at the center of the first screen plate 308 and the heavy slag inlet 305 at the tangent of the outer circular surface of the tank body 301, the distribution positions of the heavy and light slag after centrifugal motion can be better matched, thereby facilitating the collection and discharge of medium-heavy and light slag, and thus improving the impurity removal efficiency of the slurry. Valves are installed on the external pipes of both the light slag inlet 306 and the heavy slag inlet 305.

[0041] Furthermore, the tank 301 is arranged horizontally. Understandably, the horizontal arrangement of the tank 301 facilitates the flattening of the overall device, thereby reducing the space occupied by the overall device. At the same time, it can prevent heavy and light slag from accumulating at the bottom, which would result in poor separation effect when the device is set vertically.

[0042] Optionally, a scraper is connected to the agitator 302, which rotates synchronously with the agitator 302 to scrape the first screen plate 307. Understandably, the scraper facilitates the removal of material adhering to or clogging the first screen plate 307, thereby preventing clogging and ensuring efficient discharge of good slurry and the overall operation of the device. The agitator 302 can pass through the center of the screen plate, and the first screen plate 307 can be circular to allow for more thorough scraping by the rotating scraper.

[0043] Optionally, the sieve holes of the first sieve plate 307 are arranged to gradually increase in size along its flow direction. Understandably, by arranging the sieve holes of the first sieve plate 307 to gradually increase in size along its flow direction, it is easier to increase the speed at which the slurry passes through the sieve holes while maintaining the filtration effect of the first sieve plate 307, thereby improving the filtration efficiency. The sieve holes can be stepped holes with varying diameters or conical holes.

[0044] Optionally, the integrated impurity removal machine 3 includes a drive unit 309, which is connected to the agitator 302 to drive the agitator 302 to rotate. Understandably, connecting the agitator 302 to the drive unit 309 facilitates the rotation of the agitator 302, thereby facilitating the rotational movement of the slurry within the tank 301. The drive unit 309 can be a structure consisting of a motor, belt, and pulley.

[0045] Optionally, water pumps 8 are installed on the external pipes between the pulper 1 and the coarse pulp tank 2, the external pipes between the coarse pulp tank 2 and the feed inlet 303, and the external pipes connecting to the good pulp outlet 41. Understandably, by installing water pumps 8, the flow rate and power of the slurry after organic waste pulping can be increased between the coarse pulp tank 2, the integrated impurity removal machine 3, and the good pulp tank 4, thereby ensuring the discharge efficiency of good pulp and the separation efficiency of light and heavy slag. Specifically, the water pump 8 on the pipe between the coarse pulp tank 2 and the integrated impurity removal machine 3 can be an impurity removal pump, and water pumps 8 can be installed on the external pipes through which slurry flows between each device to ensure the slurry transport efficiency.

[0046] Optionally, the separation device 602 has a screw conveyor and a conveying channel adapted to the screw conveyor. A second screen plate is provided within the conveying channel. When the screw conveyor rotates, it discharges the heavy slag and allows the slurry on the heavy slag to drain through the second screen plate. Understandably, by cooperating with the second screen plate within the conveying channel, the heavy slag can fully contact and roll with the second screen plate during the rotation of the screw conveyor, thereby facilitating the separation of the slurry from the heavy slag and its drainage through the screen openings of the second screen plate. The drained slurry is collected and then pumped back to the coarse slurry tank 2, avoiding waste of slurry. The heavy slag discharge outlet of the separation device 602 can be inclined upwards.

[0047] In addition, a drain port 310 is provided at the bottom of the tank 301. Understandably, the drain port 310 facilitates the discharge of substances other than heavy slag, light slag, and good liquid, thereby ensuring the cleanliness and operation of the entire unit. The external pipeline of the drain port 310 is equipped with an automatic valve, facilitating switching between continuous and batch operation of the entire unit. When there is little light slag in the slurry, the light slag can be discharged from the drain port 310 by closing the valve.
