Description

Technical Field

[0001] This invention relates to the field of solid waste processing technology, and more specifically to a solid-liquid separation device for solid waste processing. Background Technology

[0002] Solid waste needs to be processed after recycling. Since solid waste contains liquid, and liquid is prone to bacterial growth and environmental pollution, solid-liquid separation is required before processing to prevent solid waste from polluting the environment during processing. Firstly, in existing solid-liquid separation devices, when processing solid waste, the solid waste contains a large amount of dust particles. These dust particles, when mixed with the material, act like "abrasives," causing high-speed friction against all the screens during solid-liquid separation. Furthermore, the dust mixed with the liquid easily clogs the filter screen and blocks the discharge filtrate channel. Therefore, before solid-liquid separation, dust removal treatment is necessary. Existing technology generally uses centrifugal devices to remove dust dispersed in the air when solid waste is fed in. Under the action of centrifugal force, the dust is separated from the air, thereby achieving the dust removal effect. In order to reduce the radius and increase the centrifugal force, this method generally uses a conical cylinder, which results in the bottom dust discharge port being too narrow, making it easy to get clogged during dust discharge. Secondly, under the existing technology, after solid-liquid separation of solid waste, the dry material is prone to stagnation and blockage at the discharge port of the device, thus affecting the normal operation of the device. Therefore, in order to solve the above problems, there is a need to provide a solid-liquid separation device for solid waste processing. Summary of the Invention

When the wall block is tilted, the wall channel is closed, and the airflow blows at an angle to the discharge port of the conical cylinder to clear the blockage.

[0009] Furthermore, the bottom dust outlet of the conical cylinder is provided with uniformly distributed wall grooves. A wall block is movably installed in the wall groove by means of a shaft. The shaft is movably sleeved on both sides of the wall groove and fixedly connected to the wall block. A cavity is provided inside the wall block. A leakage channel is provided at the bottom of the cavity. The upper end of the wall groove is provided with an arc-shaped surface and an inclined surface. The curvature of the arc-shaped surface is consistent with that of the upper arc surface of the wall block. A servo motor is fixedly installed on the outer side of the bottom of the conical cylinder. The drive shaft of the servo motor is connected to the shaft of the fixedly connected wall block.

[0010] Furthermore, a dust collection chamber is provided at the bottom dust discharge port of the conical cylinder, and a wall channel is opened in the inner wall of the conical cylinder. The bottom of the wall channel is connected to the vertical cavity. An air pump is fixedly installed on the outer side of the conical cylinder. A connecting pipe is fixedly connected to the output end of the air pump. The connecting pipe is connected to the upper end of the wall channel. A flexible hose is fixedly connected to the bottom side of the connecting pipe. A pressure relief valve is provided at the connection between the flexible hose and the connecting pipe.

[0011] Furthermore, a docking electric cylinder is fixedly installed on the bottom side of the conical cylinder, and an end block is fixedly connected to the end of the drive shaft of the docking electric cylinder. A cavity block is fixedly installed on the end block, and the cavity block is connected to the bottom of the hose. A wedge is provided at the front end of the cavity block, and the wedge fits into the leakage channel.

[0012] Furthermore, the unblocking assembly includes a fixed rod, which is fixedly connected to the outside of the end plate. A fixed plate is fixedly installed at the end of the shaft of the fixed rod, and an unblocking motor is fixedly installed on the outside of the fixed plate.

A sleeve column is sleeved on the front end of the shaft of the support shaft, and the sleeve column is movably sleeved in the ring column.

[0014] The technical effects and advantages of this invention are as follows: When solid waste is fed, the dust particles it carries will disperse in the air inside the dust discharge bin. The fan exhausts the air outward, and the airflow carrying the dust enters the air duct after passing through the dust collection filter plate. It then rushes into the cylinder in the tangential direction of the inner wall of the cone. Under the action of centrifugal force, the dust-laden airflow rotates at high speed. The denser dust is thrown to the wall and slides down by gravity. Clean air is discharged outward from the center through the exhaust pipe. When dust is discharged from the bottom outlet of the conical cylinder, the air pump starts to blow air into the wall channel. The airflow passes through the connected cavity and blows downward from the leak. This accelerates the airflow rate at the bottom outlet of the conical cylinder, thus facilitating dust removal. When the bottom outlet of the conical cylinder is blocked, the servo motor drives the wall block to rotate, so that the side of the wall block fits against the inclined surface. At this time, the docking electric cylinder drives the cavity block to dock and connect with the cavity. The wedge plate fits with the leak and is limited. Since the bottom outlet of the wall channel is blocked by the wall block in this state, the air pressure increases and the airflow enters the hose through the pressure relief valve. It is then blown out from the cavity at an angle downward through the cavity block, thereby blowing air out the dust and impurities blocking this place. After the wall groove is opened, it is also convenient for the impurities blocking this place to be discharged. In this way, the impurities blocking the bottom dust outlet are blown out and cleared. When the wall block is in a vertical state, the airflow accelerates and discharges material downwards. At this time, the airflow flows at a uniform speed, which causes the dust to be discharged downwards from the center position. When the wall block is in an inclined state, the airflow is depressurized through the pressure relief valve, the gas flow rate changes within a certain range, and the airflow direction changes to oblique downwards, which has an impact effect on the dust blocking the blockage, thereby improving the unblocking performance. When dry material accumulates and becomes blocked at the outlet of the discharge cylinder, the unblocking motor drives the turntable to rotate, which in turn drives the ring column to rotate. The electric cylinder drives the ring column to move backward, so that the rotating blades gradually enter the outlet of the discharge cylinder, thereby crushing the dry material blocked there, so that the dry material can fall smoothly into the collection box for collection.

Since the above-described methods are conventional techniques known to those skilled in the art, the specific structure and working principle of the device will not be described in detail in this embodiment.

The wind duct 306 is fixedly connected to the conical cylinder 307 in the tangential direction of the cylinder wall. An exhaust pipe 308 is fixedly installed in the conical cylinder 307. The bottom dust discharge port of the conical cylinder 307 is provided with uniformly distributed wall grooves 309. A wall block 310 is movably installed in the wall groove 309 by means of a shaft. The shaft is movably sleeved on both sides of the wall groove 309 and fixedly connected to the wall block 310. A cavity 311 is provided inside the wall block 310. A leakage channel 312 is provided at the bottom of the cavity 311. The upper end of the wall groove 309 is provided with an arc surface 313 and an inclined surface 314. The arc surface 313 has the same curvature as the upper arc surface of the wall block 310. A servo motor 315 is fixedly installed on the outer side of the bottom of the conical cylinder 307. The drive shaft of the servo motor 315 is connected to the shaft of the fixedly connected wall block 310. A dust collection chamber 316 is provided at the bottom dust discharge port of the conical cylinder 307. A wall channel 317 is opened in the inner wall of the conical cylinder 307. The bottom of the wall channel 317 is connected to the vertical cavity 311. An air pump 318 is fixedly installed on the outside of the conical cylinder 307. A connecting pipe 319 is fixedly connected to the output end of the air pump 318. The connecting pipe 319 is connected to the upper end of the wall channel 317. A flexible hose 320 is fixedly connected to the bottom side of the connecting pipe 319. A pressure relief valve 321 is provided at the connection between the flexible hose 320 and the connecting pipe 319. A docking electric cylinder 322 is fixedly installed on the bottom side of the conical cylinder 307. An end block 323 is fixedly connected to the end of the drive shaft of the docking electric cylinder 322. A cavity block 324 is fixedly installed on the end block 323. The cavity block 324 is connected to the bottom of the hose 320. A wedge plate 325 is provided at the front end of the cavity block 324. The wedge plate 325 fits into the channel 312. When the device is in use, the dust particles carried by the solid waste are dispersed in the air inside the dust discharge bin 301 when the solid waste is fed. The fan 304 exhausts the air outward. The airflow carrying the dust enters the air duct 306 after passing through the dust suction filter plate 302. It then rushes into the inner wall of the cone-shaped cylinder 307 in a tangential direction. Under the action of centrifugal force, the dust-laden airflow rotates at high speed. The denser dust is thrown to the wall and slides down by gravity. Clean air is discharged outward from the center through the exhaust pipe 308. When dust is discharged from the outlet at the bottom of the conical cylinder 307, the air pump 318 starts to blow air into the wall channel 317. The airflow passes through the cavity 311 connected to it and blows downward from the leakage channel 312. This accelerates the airflow rate at the outlet at the bottom of the conical cylinder 307, thus facilitating dust removal. When the outlet at the bottom of the conical cylinder 307 becomes blocked, the servo motor 315 drives the wall block 310 to rotate, causing the side of the wall block 310 to fit against the inclined surface 314. At this time, the docking electric cylinder 322 drives the cavity block 324 to... The cavity 311 is connected and connected, the wedge plate 325 is engaged with the leakage channel 312 and limited, since the bottom outlet of the wall channel 317 is blocked by the wall block 310 in this state, after the air pressure is increased, the airflow enters the hose 320 through the pressure relief valve 321, and is blown out from the cavity 311 at an angle downward through the cavity block 324, thereby blowing air out the dust and impurities blocked here. After the wall groove 309 is opened, it is also convenient for the impurities blocked here to be discharged. In this way, the impurities blocked at the bottom dust outlet are blown out and cleared. It should be further explained that when the wall block 310 is in a vertical state, the airflow accelerates downward to discharge the material. At this time, the airflow flows at a uniform speed, which causes the dust to be discharged downward from the center position in a more concentrated manner. When the wall block 310 is in an inclined state, the airflow is depressurized through the pressure relief valve 321, the gas flow rate changes within a certain range, and the airflow direction changes to oblique downward, which has an impact effect on the dust blocking the blockage, thereby improving the unblocking performance.

[0021] Reference Figure 9 The unblocking assembly 4 includes a fixed rod 401, which is fixedly connected to the outside of the end plate 108. A fixed plate 402 is fixedly installed at the end of the shaft of the fixed rod 401. An unblocking motor 403 is fixedly installed on the outside of the fixed plate 402. A partition plate 404 is also fixedly sleeved on the shaft of the fixed rod 401. A turntable 405 is movably sleeved in the partition plate 404. The drive shaft of the unblocking motor 403 is fixedly connected to the turntable 405. A push cylinder 406 is fixedly installed on the outside of the turntable 405. A ring column 407 is fixedly connected to the drive shaft of the push cylinder 406. The ring column 407 is movably sleeved in the end plate 108. The rear end of the ring column 407 is provided with evenly distributed blades 408. A sleeve column 409 is sleeved on the front end of the shaft of the support shaft 109. The sleeve column 409 is movably sleeved in the ring column 407. When the device is in use, if the dry material accumulates and becomes blocked at the outlet end of the discharge cylinder 107, the unblocking motor 403 drives the turntable 405 to rotate, thereby driving the ring column 407 to rotate. The push cylinder 406 drives the ring column 407 to move backward, so that the rotating blade 408 gradually enters the outlet end of the discharge cylinder 107, thereby crushing the dry material blocked there, so that the dry material can fall smoothly into the collection box 112 for collection.

[0022] The working principle of this invention is as follows: When dust particles are dispersed in the air inside the dust discharge chamber 301, the airflow carries the dust and rushes into the conical cylinder 307 along the tangential direction of the inner wall. The dust-laden airflow rotates at high speed, and the dense dust is thrown to the wall and slides down by gravity, while clean air is discharged outward. After the air pump 318 is started, the airflow blows downward from the leakage channel 312 through the cavity 311. When the bottom outlet of the conical cylinder 307 is blocked, the servo motor 315 drives the side of the wall block 310 to fit with the inclined surface 314. At this time, the docking electric cylinder 322 drives the cavity block 324 to dock with and connect with the cavity 311. The wedge plate 325 fits with the leakage channel 312 and performs a limit. Since the bottom outlet of the wall channel 317 is blocked by the wall block 310 in this state, after the air pressure is increased, the airflow enters the hose 320 through the pressure relief valve 321 and blows out from the cavity 311 at a downward angle through the cavity block 324, thereby blowing air out the dust and impurities blocked here. After the wall groove 309 is opened, it is also convenient for the impurities blocked here to be discharged. When dry material accumulates and becomes blocked at the outlet of the discharge cylinder 107, the unblocking motor 403 drives the turntable 405 to rotate, thereby driving the ring column 407 to rotate. The electric cylinder 406 drives the ring column 407 to move backward, so that the rotating blade 408 gradually enters the outlet of the discharge cylinder 107, thereby crushing the dry material blocked there, so that the dry material can fall smoothly into the collection box 112 for collection.
