Description

Technical Field

[0001] The invention belongs to the technical field of dust purification, in particular to a workshop dust purification device. Background Art

[0002] Dust generally refers to tiny particles consisting of solid particles that can occur naturally or as a result of human activities. They range in size from a few nanometers to hundreds of micrometers. Dust particles vary in density, shape, hardness, and chemical properties, which determine how dust behaves in the environment and its potential health effects.

[0003] A Chinese patent with publication number CN106215581A discloses a high-temperature exhaust gas waste heat recovery and dust purification device for factories. By adding a water storage device, the heat in the high-temperature exhaust gas can be recovered and utilized by cold water, thereby heating the cold water. The heated hot water can be used for employee bathing or heating in winter, etc.; by adding multiple groups of heat exchange tubes and heat-conducting aluminum sheets, the heat in the high-temperature exhaust gas can be fully transferred to the cold water, thereby heating the cold water, and the flow direction of the high-temperature exhaust gas is opposite to that of the cold water, which can greatly improve the efficiency of heat exchange and improve the recovery rate of heat energy; through the exhaust gas dispersion device and the exhaust gas dispersion port, the exhaust gas after cooling can be evenly dispersed in the exhaust gas purification tower.

[0004] In the current existing technology, when water spray is used to purify dust, the water collides with particles in the exhaust gas and solidifies to form solid blocks, thereby achieving the effect of purifying dust. When this method is used, the solid blocks will flow out of the device together with the water flow, which wastes water resources.

[0005] To this end, the present invention provides a workshop dust purification device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a workshop dust purification device described in the present invention comprises a base, a bottom shell body is fixedly installed in the middle of the base, an upper shell body is fixedly installed on the top of the bottom shell body, a dust inlet is fixedly installed on the top of the inner wall of the upper shell body, a water applicator is fixedly installed on the top of the inner wall of the upper shell body, a limited water box is fixedly installed in the middle of the inner wall of the upper shell body, a return water component is arranged inside the limited water box, the return water component is used to recycle the water sprayed by the water applicator, so as to save water resources, a briquetting component is arranged inside the bottom shell body, the briquetting component is used to squeeze out excess water in the water-dust mixture on the one hand, and to mold the water-dust mixture into blocks on the other hand, so as to facilitate subsequent collection, so as to play the role of squeezing water into blocks;

[0008] Through an external vacuum device, the dust is drawn from the dust inlet into the upper shell body. When the dust enters the upper shell body, the water applicator on the top of the upper shell body sprays water to make the water react with the particles in the dust and solidify to form a water-dust mixture. Then the water-dust mixture enters the water limiting box. The briquetting assembly in the water limiting box operates on the water-dust mixture. The briquetting assembly squeezes out excess water in the water-dust mixture and molds the water-dust mixture into blocks for subsequent collection, playing the role of squeezing water into blocks. During operation, the water squeezed out by the briquetting assembly is recovered and recycled through the return water assembly, and the blocks with the water squeezed out will fall into the bottom shell body for collection.

[0009] Preferably, an inclined sliding table is fixedly installed between the water limiting box and the water applicator, a plurality of water spray heads are fixedly installed at the bottom of the water applicator, and a plurality of water inlets are fixedly installed on the outer wall of the water applicator. When dust is passed into the upper shell body, the water applicator sprays water through the multiple water spray heads at the bottom, so that the dust reacts with water and solidifies. Through the continuous injection of water, the agglomerated dust will gradually become a water-dust mixture, and then slide into the water limiting box through the inclined sliding table, and the briquetting assembly and the return water assembly operate on it to play the role of spraying water. The water inlet is set to facilitate the water supply to the water applicator.

[0010] Preferably, the water return component includes a separation cylinder, which is fixedly installed in the middle of the inner wall of the water limiting box, and the inner wall of the separation cylinder is provided with multiple water leakage holes, the top of the separation cylinder is fixedly installed with an oblique flow curved plate, the inner wall of the upper shell body is fixedly installed with a water return device, multiple through pipes are fixedly installed between the water limiting box and the water return device, the water limiting box is placed just above the bottom shell body, and multiple water return pipes are fixedly installed between the water return device and the water applicator. When the water-dust mixture enters the water limiting box, the water-dust mixture flows smoothly along the oblique flow curved plate into the separation cylinder. When the water-dust mixture in the separation cylinder accumulates to a certain amount, the water-dust mixture in the separation cylinder is squeezed by the pressing block assembly. When the water-dust mixture is pressurized, the moisture in the water-dust mixture will flow out into the water limiting box through the water leakage hole on the separation cylinder, and the outflowing water will flow into the water return device through multiple through pipes. The water return device sends the discharged water back to the water applicator through the return pipe, so as to recycle the water flow, reduce the waste of resources, and save water resources.

[0011] Preferably, a plurality of air pumps are fixedly installed at the bottom of the oblique flow curved plate, and air flow pipes are fixedly installed at the air outlet ends of the plurality of air pumps. An air dispersion ring is fixedly installed on the outer wall of the bottom end of the separation cylinder, and one end of the plurality of air flow pipes is fixedly connected to the outer wall of the air dispersion ring. When water is discharged from the water leakage port in the separation cylinder, the air pump introduces air flow to the air dispersion ring through the air flow pipe, and the air flow pushes the water to flow into the through pipe. The setting of the air flow can speed up the speed of water flowing into the through pipe, thereby speeding up the speed of water return and improving the operation rate of water return.

[0012] Preferably, the briquetting assembly includes a motor, which is placed in the middle of the bottom of the inner wall of the bottom shell body, and a shaft is fixedly installed on the output end of the motor, and a pressure plate is fixedly installed on the top of the shaft, and the outer wall of the pressure plate is slidably connected to the inner wall of the separation cylinder. When briquetting, the motor drives the pressure plate downward through the shaft, and the pressure plate is pressed downward to squeeze the water-dust mixture in the separation cylinder, and the water in the water-dust mixture is squeezed out. On the one hand, the excess water in the water-dust mixture is squeezed out, and on the other hand, the water-dust mixture is molded into blocks for subsequent collection, thereby playing the role of squeezing water and molding blocks.

[0013] Preferably, moving plates are symmetrically arranged inside the bottom shell body, and blocking plates are fixedly installed on the tops of the two moving plates, and extruding plate knives are symmetrically fixedly installed on the outer walls of the shaft rod, and push plates are fixedly installed on the bottom ends of the two moving plates. The bottoms of the two extruding plate knives are slidingly connected to the outer walls of the two push plates respectively. When the motor drives the pressure plate to press down, the motor drives the extruding plate knives to move downward through the shaft rod. When the extruding plate knife moves downward, the extruding plate knife squeezes the push plate at the lower end of the moving plate to move backward, and the blocking plate on the top of the moving plate will be squeezed by the extruding plate knife and pushed to open from the bottom of the separation cylinder. At this time, the dust blocks squeezed into blocks will fall into the inside of the bottom shell body for block taking operation.

[0014] Preferably, a sliding rod is fixedly installed on the outer walls of the two moving plates, and a reset spring is fixedly installed between the moving plate and the inner wall of the bottom shell body. The sliding rod is slidably connected to the inner wall of the bottom shell body, and the reset spring is placed on the outside of the sliding rod. When the moving plate moves backward, the moving plate pushes the sliding rod to squeeze the reset spring to slide on the bottom shell body. When the dust block falls down, the motor drives the plate extrusion knife to reset through the shaft rod, and the moving plate will be reset by the elastic force of the reset spring, so that the two blocking plates are closed again, thereby playing the role of limiting and blocking the flow.

[0015] Preferably, cutting knives are symmetrically fixedly installed on the inner wall of the bottom shell body, and the two cutting knives are respectively placed on both sides of the shaft rod, and the positions of the two shaft rods and the positions of the two squeezing plate knives are staggered. When the dust block slides into the bottom shell body from the separation cylinder under the pressure of the pressure plate, the dust block is squeezed by the pressure plate through the top. Through the position setting of the cutting knives, the dust block will be cut by the cutting knives while sliding and divided into two halves. Subsequently, the squeezing plate knives are reset by the shaft rod, and the squeezing plate knives cut back the two halves of the dust block. Through this operation, the dust block will be divided into four and fall into the bottom of the bottom shell body. Through the staggered position setting of the cutting knives and the squeezing plate knives, the dust block can be divided into four, which is convenient for peeling off and removing the dust block from the shaft rod, thereby playing a role in taking out the block.

[0016] Preferably, a plurality of blowing plates are fixedly mounted on the inner wall of the inclined sliding table, and air inlets are fixedly mounted on the outer walls of the plurality of blowing plates. An oblique blowing port is provided on the inner wall of the blowing plate, and the oblique port angle of the blowing plate is consistent with the inclined surface angle of the inclined sliding table. When the water-dust mixture slides on the inclined sliding table, an air blowing device is connected externally at the air inlet, and air flow is blown out through the oblique blowing port opened under the air blow plate, which can accelerate the sliding of the water-dust mixture on the inclined sliding table, thereby accelerating the purification operation.

[0017] Preferably, a slag cutting plate is fixedly installed on the inner wall of the bottom shell body, and the slag cutting plate is placed outside the motor. When the dust block falls, the dust block divided into four parts will fall into the bottom shell body separated by the slag cutting plate. Due to the position setting of the slag cutting plate, when the dust block enters the bottom shell body, the top of the slag cutting plate can provide a limiting support for the dust block.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. A workshop dust purification device described in the present invention, when the water-dust mixture in the separation cylinder accumulates to a certain amount, the water-dust mixture in the separation cylinder is squeezed by a pressing block assembly. When the water-dust mixture is pressurized, the moisture in the water-dust mixture will flow out into the water limiting box through the water leakage port on the separation cylinder, and the outflowing water will flow into the return water device through multiple through pipes. The return water device returns the discharged water to the water applicator through the return water pipe, so as to recycle the water flow, reduce the waste of resources, and play a role in saving water resources. At the same time, the air diffuser ring diffuses air, and the airflow pushes the water to flow into the through pipe. The setting of the airflow can speed up the speed of the water flowing into the through pipe, thereby speeding up the speed of the return water and improving the operation rate of the return water.

[0020] 2. The workshop dust purification device described in the present invention drives a pressure plate downward through a motor via a shaft rod. When the pressure plate is pressed downward, the water-dust mixture in the separation cylinder is squeezed to squeeze out the water in the water-dust mixture. On the one hand, the excess water in the water-dust mixture is squeezed out, and on the other hand, the water-dust mixture is molded into blocks for subsequent collection, thereby playing the role of squeezing water and molding blocks.

[0021] 3. The workshop dust purification device described in the present invention has a cutting knife position setting, and the dust block will be cut by the cutting knife while sliding and divided into two halves. Then the shaft rod drives the plate squeezing knife to reset, and the plate squeezing knife cuts back the two halves of the dust block. The staggered position setting of the cutting knife and the plate squeezing knife can divide the dust block into four parts, which is convenient for peeling off and removing the dust block from the shaft rod, thereby playing a role in removing the dust block.

[0022] 4. The workshop dust purification device described in the present invention is that when the water-dust mixture slides on the inclined sliding table, an air blowing device is connected to the air inlet. The air flow is blown out through the inclined blowing port opened under the blowing plate, which can accelerate the sliding of the water-dust mixture on the inclined sliding table, thereby accelerating the purification efficiency.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figures 1 to 9 As shown, a workshop dust purification device according to an embodiment of the present invention comprises a base 30, a bottom shell body 1 is fixedly installed in the middle of the base 30, an upper shell body 4 is fixedly installed on the top of the bottom shell body 1, a dust inlet 3 is fixedly installed on the top of the upper shell body 4, a water applicator 7 is fixedly installed on the top of the inner wall of the upper shell body 4, a limited water box 14 is fixedly installed in the middle of the inner wall of the upper shell body 4, a return water component is arranged inside the limited water box 14, the return water component is used to recycle the water sprayed by the water applicator 7, so as to save water resources, a briquetting component is arranged inside the bottom shell body 1, the briquetting component is used to squeeze out excess water in the water-dust mixture on the one hand, and to mold the water-dust mixture into blocks on the other hand, so as to facilitate subsequent collection, so as to play the role of squeezing water into blocks;

[0036] In the current existing technology, when water spray is used to purify dust, water collides with particles in the exhaust gas and solidifies to form solid blocks, thereby achieving the function of purifying dust. When this method is in operation, the solid blocks will flow out of the device together with the water flow, which wastes water resources.

[0037] The dust is extracted from the dust inlet 3 into the upper shell body 4 by an external vacuum device. When the dust enters the upper shell body 4, the water applicator 7 on the top of the upper shell body 4 sprays water to make the water react with the particles in the dust to solidify and agglomerate into a water-dust mixture. Then the water-dust mixture enters the water-limiting box 14. The briquetting component in the water-limiting box 14 operates on the water-dust mixture, squeezes out excess water in the water-dust mixture, and at the same time, molds the water-dust mixture into blocks for subsequent collection, playing the role of squeezing water and molding blocks. During operation, the water squeezed out by the briquetting assembly is recovered by the water return assembly and recycled, and the plastic blocks with water squeezed out will fall into the bottom shell body 1 for collection. The cooperation between the briquetting assembly and the water return assembly can solve the problem of purifying dust by forming solid blocks after collision between water and particles in the exhaust gas. When this method is in operation, the solid blocks will flow out of the device together with the water flow, which is a waste of water resources. It should be noted here that the amount of water sprayed by the water applicator 7 needs to be actually measured.

[0038] like Figures 3 to 5 As shown, an inclined sliding platform 6 is fixedly installed between the water limiting box 14 and the water applicator 7, a plurality of water spray heads 13 are fixedly installed at the bottom of the water applicator 7, and a plurality of water inlets 26 are fixedly installed on the outer wall of the water applicator 7;

[0039] When the dust is passed into the upper shell body 4, the water applicator 7 sprays water through the multiple water spray heads 13 at the bottom, so that the dust reacts with water and solidifies. Through the continuous spraying of water, the agglomerated dust will gradually become a water-dust mixture, and then slide into the water limiting box 14 through the inclined sliding table 6. The briquetting assembly and the return water assembly operate on it to play the role of spraying water. The setting of the water inlet 26 is to facilitate the water supply to the water applicator 7. It should be noted here that the spraying direction of the multiple water spray heads 13 is to spray downward at an angle toward the middle of the water limiting box 14. The inclination angle of the water limiting box 14 should be consistent with the inclination angle of the inclined sliding table 6, and the water flow sprayed by the water spray head 13 is in the form of mist.

[0040] like Figures 3 to 8 As shown, the water return assembly includes a separation cylinder 9, which is fixedly installed in the middle of the inner wall of the water limiting box 14, and a plurality of water leakage holes 29 are opened on the inner wall of the separation cylinder 9. An oblique flow curved plate 11 is fixedly installed on the top of the separation cylinder 9, and a water return device 5 is fixedly installed on the inner wall of the upper shell body 4. A plurality of through pipes 32 are fixedly installed between the water limiting box 14 and the water return device 5. The water limiting box 14 is placed directly above the bottom shell body 1, and a plurality of water return pipes 2 are fixedly installed between the water return device 5 and the water applicator 7;

[0041] When the water-dust mixture enters the water limiting box 14, the water-dust mixture flows smoothly along the oblique curved plate 11 into the separation cylinder 9. When the water-dust mixture in the separation cylinder 9 accumulates to a certain amount, the water-dust mixture in the separation cylinder 9 is squeezed by the pressing block assembly. When the water-dust mixture is compressed, the moisture in it will flow out into the water limiting box 14 through the water leakage port 29 on the separation cylinder 9, and the outflowing water will flow into the return water device 5 through multiple through pipes 32. The return water device 5 returns the discharged water to the water applicator 7 through the return water pipe 2, so as to recycle the water flow, reduce the waste of resources, and save water resources. It should be noted here that the mass of the water-dust mixture accumulated in the separation cylinder 9 needs to be actually measured and calculated.

[0042] like Figures 7 and 8 As shown, a plurality of air pumps 15 are fixedly installed at the bottom of the oblique flow curved plate 11, and air flow pipes 16 are fixedly installed at the air outlet ends of the plurality of air pumps 15. A gas dispersion ring 17 is fixedly installed on the outer wall of the bottom end of the separation cylinder 9, and one end of the plurality of air flow pipes 16 is fixedly connected to the outer wall of the gas dispersion ring 17.

[0043] When water is discharged from the water leakage port 29 in the separation cylinder 9, the air pump 15 introduces air flow to the air dispersion ring 17 through the air flow pipe 16, and the air flow pushes the water to flow into the through pipe 32. The setting of the air flow can speed up the speed of water flowing into the through pipe 32, thereby speeding up the speed of return water and improving the return water operation rate. It should be noted here that the power of the air pump 15 needs to be actually measured and calculated.

[0044] like Figures 8 to 9 As shown, the pressing block assembly includes a motor 21, which is placed in the middle of the bottom of the inner wall of the bottom shell body 1, and the output end of the motor 21 is fixedly installed with a shaft 18, and the top of the shaft 18 is fixedly installed with a pressing plate 10, and the outer wall of the pressing plate 10 is slidably connected to the inner wall of the separation cylinder 9;

[0045] When pressing blocks, the motor 21 drives the pressing plate 10 to press down through the shaft 18. When the pressing plate 10 is pressed down, the water-dust mixture in the separation cylinder 9 is squeezed to squeeze out the water in the water-dust mixture. On the one hand, the excess water in the water-dust mixture is squeezed out, and on the other hand, the water-dust mixture is plasticized into blocks for subsequent collection, which plays the role of squeezing water into blocks. It should be noted here that a dust-proof membrane is arranged on the outside of the motor 21.

[0046] like Figures 8 to 9 As shown, the bottom shell body 1 is symmetrically provided with moving plates 25, the tops of the two moving plates 25 are fixedly installed with blocking plates 19, the outer wall of the shaft 18 is symmetrically fixedly installed with plate extrusion knives 24, the bottom ends of the two moving plates 25 are fixedly installed with push plates 23, and the bottoms of the two plate extrusion knives 24 are slidably connected with the outer walls of the two push plates 23 respectively;

[0047] When the motor 21 drives the pressure plate 10 to press down, the motor 21 drives the extruding plate knife 24 to move downward through the shaft 18. When the extruding plate knife 24 moves downward, the extruding plate knife 24 squeezes the push plate 23 at the lower end of the shifting plate 25 to move backward, and the blocking plate 19 on the top of the shifting plate 25 will be squeezed and pushed by the extruding plate knife 24 to open from the bottom of the separation cylinder 9. At this time, the dust blocks squeezed into blocks will fall into the bottom shell body 1 for block taking. It should be noted that the opening operation of the two blocking plates 19 should be after the pressure plate 10 completes the water squeezing operation on the water-dust mixture. The distance between the extruding plate knife 24 and the push plate 23 needs to be actually measured and calculated, and the hardness of the water-dust mixture after being pressed into blocks needs to be actually measured and calculated. Sealing rings should be provided on the inner sides of the two blocking plates 19.

[0048] like Figures 8 to 9 As shown, the outer walls of the two moving plates 25 are fixedly mounted with slide bars 31, a return spring 22 is fixedly mounted between the moving plates 25 and the inner wall of the bottom shell body 1, the slide bars 31 are slidably connected to the inner wall of the bottom shell body 1, and the return spring 22 is placed outside the slide bars 31;

[0049] When the moving plate 25 moves backward, the moving plate 25 pushes the sliding rod 31 to squeeze the reset spring 22 to slide on the bottom shell body 1. When the dust block falls down, the motor 21 drives the plate squeezing knife 24 to reset through the shaft 18, and the moving plate 25 will be reset by the elastic force of the reset spring 22, so that the two blocking plates 19 are closed again, which plays the role of limiting and blocking the flow.

[0050] like Figures 8 to 9 As shown, the inner wall of the bottom shell body 1 is symmetrically fixed with cutting knives 20, and the two cutting knives 20 are respectively placed on both sides of the shaft 18, and the positions of the two shafts 18 and the positions of the two plate extrusion knives 24 are staggered;

[0051] When the dust block is pressed by the pressure plate 10 and slides into the bottom shell body 1 from the separation cylinder 9, the dust block is squeezed by the pressure plate 10 through the top. Through the position setting of the cutting knife 20, the dust block will be cut by the cutting knife 20 while sliding and divided into two halves. Then, the squeezing knife 24 is driven to reset by the shaft rod 18, and the squeezing knife 24 cuts back the two halves of the dust block. Through this operation, the dust block will be divided into four and fall into the bottom of the bottom shell body 1. Through the staggered position setting of the cutting knife 20 and the squeezing knife 24, the dust block can be divided into four, which is convenient for peeling off the dust block from the shaft rod 18 and removing the dust block, thereby playing the role of removing the block. It should be noted here that the two cutting knives 20 slide in contact with the outer wall of the shaft rod 18.

[0052] like Figures 5 and 6 As shown, a plurality of blowing plates 12 are fixedly mounted on the inner wall of the inclined sliding table 6, and an air inlet 27 is fixedly mounted on the outer wall of each of the blowing plates 12. An oblique blowing port 28 is provided on the inner wall of the blowing plate 12, and the oblique port angle of the blowing plate 12 is consistent with the inclined surface angle of the inclined sliding table 6;

[0053] When the water-dust mixture slides on the inclined sliding table 6, an air blowing device is connected to the air inlet 27 to blow air through the inclined blowing port 28 opened below the blowing plate 12, which can speed up the sliding of the water-dust mixture on the inclined sliding table 6, thereby speeding up the purification operation.

[0054] like Figures 8 to 9 As shown, a slag cutting plate 8 is fixedly installed on the inner wall of the bottom shell body 1, and the slag cutting plate 8 is placed outside the motor 21;

[0055] When the dust block falls, the dust block divided into four parts will fall into the bottom shell body 1 separated by the slag cutting plate 8. Due to the position setting of the slag cutting plate 8, when the dust block enters the bottom shell body 1, the top of the slag cutting plate 8 can provide a limiting support for the dust block.

[0056] Working principle: by connecting an external vacuum device, the dust is extracted from the dust inlet 3 into the upper shell body 4. When the dust enters the upper shell body 4, the water applicator 7 on the top of the upper shell body 4 sprays water to make the water react with the particles in the dust to solidify and agglomerate into a water-dust mixture. Then the water-dust mixture enters the water-limiting box 14. The briquetting component in the water-limiting box 14 operates on the water-dust mixture. The briquetting component squeezes out excess water in the water-dust mixture and molds the water-dust mixture into blocks for subsequent collection, playing the role of squeezing water into blocks. During operation, the water squeezed out by the briquetting component is recovered and recycled through the water return component, and the blocks with water squeezed out will fall into the bottom shell body 1 for collection.

[0057] When the dust is introduced into the upper shell 4, the water applicator 7 sprays water through the multiple water spray heads 13 at the bottom, so that the dust reacts with water and solidifies. Through the continuous spraying of water, the agglomerated dust will gradually become a water-dust mixture, and then slide into the water inlet box 14 through the inclined sliding plate 6. The briquetting assembly and the water return assembly operate on it to play the role of spraying water. The setting of the water inlet 26 is to facilitate the water supply to the water applicator 7;

[0058] When the water-dust mixture enters the water-limiting box 14, the water-dust mixture flows smoothly through the oblique curved plate 11 into the separation cylinder 9. When the water-dust mixture in the separation cylinder 9 accumulates to a certain amount, the water-dust mixture in the separation cylinder 9 is squeezed by the pressing block assembly. When the water-dust mixture is compressed, the water in it will flow out of the water-limiting box 14 through the water leakage port 29 on the separation cylinder 9. The outflowing water will flow into the return water device 5 through multiple through pipes 32. The return water device 5 returns the discharged water to the water applicator 7 through the return water pipe 2, so as to recycle the water flow, reduce the waste of resources, and save water resources.

[0059] When water is discharged from the water leakage port 29 in the separation cylinder 9, the air pump 15 introduces airflow to the air diffuser ring 17 through the airflow pipe 16, and the airflow pushes the water to flow into the through pipe 32. The setting of the airflow can speed up the speed of water flowing into the through pipe 32, thereby speeding up the speed of water return and improving the operation rate of water return;

[0060] When briquetting, the motor 21 drives the pressing plate 10 to press down through the shaft 18. When the pressing plate 10 is pressed down, the water-dust mixture in the separation cylinder 9 is squeezed to squeeze out the water in the water-dust mixture. On the one hand, the excess water in the water-dust mixture is squeezed out, and on the other hand, the water-dust mixture is molded into blocks for subsequent collection, thus playing the role of squeezing water and molding blocks.

[0061] When the motor 21 drives the pressing plate 10 to press down, the motor 21 drives the plate extrusion knife 24 to move downward through the shaft 18. When the plate extrusion knife 24 moves downward, the plate extrusion knife 24 squeezes the push plate 23 at the lower end of the moving plate 25 to move backward, and the blocking plate 19 on the top of the moving plate 25 is squeezed and pushed by the plate extrusion knife 24 to open from the bottom of the separation cylinder 9. At this time, the dust blocks squeezed into blocks will fall into the bottom shell 1 to perform the block removal operation;

[0062] When the moving plate 25 moves backward, the moving plate 25 pushes the slide bar 31 to squeeze the reset spring 22 to slide on the bottom shell body 1. When the dust block falls down, the motor 21 drives the plate extrusion knife 24 to reset through the shaft 18, and the moving plate 25 will be reset by the elastic force of the reset spring 22, so that the two blocking plates 19 are closed again, which plays the role of limiting and blocking flow.

[0063] When the dust block is pressed by the pressure plate 10 and slides from the separation cylinder 9 into the bottom shell body 1, the dust block is squeezed by the pressure plate 10 through the top. Through the position setting of the cutting knife 20, the dust block will be cut by the cutting knife 20 while sliding and divided into two halves. Then, the squeezing plate knife 24 is driven to reset by the shaft rod 18, and the squeezing plate knife 24 performs a back-cutting operation on the two halves of the dust block. Through this operation, the dust block will be divided into four and fall into the bottom of the bottom shell body 1. Through the staggered position setting of the cutting knife 20 and the squeezing plate knife 24, the dust block can be divided into four, which is convenient for peeling off the dust block from the shaft rod 18, thereby playing the role of taking the block;

[0064] When the water-dust mixture slides on the inclined sliding table 6, an air blowing device is connected to the air inlet 27 to blow air through the inclined blowing port 28 opened below the air blowing plate 12, which can speed up the sliding of the water-dust mixture on the inclined sliding table 6, thereby speeding up the purification operation;

[0065] When the dust block falls, the dust block divided into four parts will fall into the bottom shell body 1 separated by the slag cutting plate 8. Due to the position setting of the slag cutting plate 8, when the dust block enters the bottom shell body 1, the top of the slag cutting plate 8 can provide a limiting support for the dust block.
