Description

Technical Field

[0001] The present invention relates to the technical field of gas purification, and particularly to a gas purification device for the preparation of potassium perchlorate. Background Art

[0002] Potassium perchlorate, as a strong oxidizing chemical raw material, is widely used in fields such as fireworks, explosives, and rocket propellants. During its preparation process, waste gas with complex components is generated, which is difficult to treat. There are particulate matters in the waste gas. During the pretreatment stages such as raw material grinding and screening, raw material particles will escape into the dust in the waste gas; during the reaction process, solid small particles generated by side reactions and debris from equipment wear are also mixed in. At the same time, the waste gas contains liquid. The condensable droplets of gases such as volatile substances generated by the reaction, water vapor during cooling, and the washing liquid droplets entrained during waste gas washing all become the sources of liquid in the waste gas. Therefore, during the preparation process of potassium perchlorate, it is necessary to use a gas purification device to treat the waste gas. The prior art usually separates the solid particles and waste liquid in the waste gas first, and then conducts subsequent treatment on the waste gas. The prior art includes purifying the waste gas by means of cyclone separation. When the waste gas containing particulate matters flows in the purification device, a high-speed rotating airflow is formed. Under the action of centrifugal force, the particulate matters with larger mass are thrown towards the outer wall of the purification device, thereby achieving the separation and purification effect.

[0003] However, in the prior art, there are the following problems: When the prior art transports waste gas through a pipeline, since the volume of the waste gas generated may be unstable, there may be a situation where the amount of waste gas in the pipeline is small during some periods, resulting in a small flow rate of the waste gas in the pipeline. The cyclone separation principle requires a relatively high gas flow rate to form a high-speed rotating eddy current, so as to separate solid particles and waste liquid by using centrifugal force. When the waste gas flow rate is small, the generated centrifugal force is low, resulting in a poor separation and purification effect. Summary of the Invention

[0004] The purpose of the present invention is to provide a gas purification device for the preparation of potassium perchlorate to solve the above problems, and to overcome the defect that in the prior art, when the waste gas flow rate is small, the generated centrifugal force is low, resulting in a poor separation and purification effect, as described in detail below.

DETAILED DESCRIPTION

[0020] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0021] Example 1 Please refer to Figure 1 - Figure 8 , a gas purification device for potassium perchlorate preparation, comprising an intake housing 1. A separation housing 2 is connected to the right side of the intake housing 1. An intake pipe 10 is connected to the top of the intake housing 1. A bellows 3 is connected through the right inner wall of the intake housing 1. A separation pipe 4 is connected to the right side of the bellows 3. A recovery pipe 6 is connected to the top of the separation housing 2. A collecting pipe 5 is connected to the left side of the recovery pipe 6. The collecting pipe 5 is located inside the separation pipe 4. One end of the separation pipe 4 away from the bellows 3 is connected to the outer wall of the recovery pipe 6. An outlet pipe 11 is connected to the top of the recovery pipe 6. A sieve mesh 21 is arranged inside the separation housing 2. An impeller 41 is installed on the inner wall of the separation pipe 4. A square pipe 42 is connected between the separation pipe 4 and the separation housing 2. After the waste gas enters the separation pipe 4, a vortex is formed through the diversion of the impeller 41, generating a certain centrifugal force, so that the solid particles in the waste gas are carried to the inner wall of the separation pipe 4 by the centrifugal force. An umbrella plate separator 61 and a wire mesh demister 62 are installed on the inner wall of the recovery pipe 6. The wire mesh demister 62 is located above the umbrella plate separator 61. The waste gas at the center of the vortex enters the recovery pipe 6 through the collecting pipe 5. Subsequently, the waste gas flows upward. The umbrella plate separator 61 in the recovery pipe 6 is used to separate the larger water droplets in the waste gas, and the wire mesh demister 62 is used to separate the smaller water droplets in the waste gas. The waste gas separated from solids and liquids is transported to the next process through the outlet pipe 11. Both the square pipe 42 and the recovery pipe 6 are located above the sieve mesh 21. A waste residue box 22 and a waste liquid box 23 are installed inside the separation housing 2. The waste residue box 22 is located to the left of the waste liquid box 23. The bottom of the sieve mesh 21 is located above the waste residue box 22. The water droplets separated by the umbrella plate separator 61 and the wire mesh demister 62 fall onto the sieve mesh 21 below. The solid particles in the separation pipe 4 also fall onto the sieve mesh 21 through the square pipe 42. The liquid passes through the sieve mesh 21 and falls into the waste liquid box 23. The solids are temporarily retained on the sieve mesh 21 and slide down the inclined plane of the sieve mesh 21 into the waste residue box 22, so that the waste liquid and the waste residue are separately collected; through the cooperation of the sieve mesh 21, the waste residue box 22, and the waste liquid box 23, the waste residue box 22 and the waste liquid box 23 can store the solid waste and liquid waste separated from the waste gas separately, avoiding chemical reactions between the solid waste and the liquid waste.

[0022] Furthermore, please refer to Figure 2 - Figure 7, further including a supercharging component 7 for increasing the flow rate of exhaust gas during purification. The supercharging component 7 includes a slide plate 71 which is slidably connected to the inner wall of the intake housing 1. A plurality of springs are provided between the bottom of the slide plate 71 and the bottom inner wall of the intake housing 1. A chute plate 72 is slidably installed on the inner wall of the intake housing 1. The chute plate 72 is located below the air box 3. A partition is provided in the intake housing 1 to separately partition the space at the bottom of the slide plate 71. The top of the chute plate 72 is connected with a connecting rod 74 which is slidably connected through the bottom inner wall of the air box 3. A sliding seat 75 is slidably connected to the inner wall of the air box 3. Two air-blocking plates 76 are hinged on the sliding seat 75. The right side of the slide plate 71 is connected with a sliding shaft 73 through a bracket. A parallelogram chute is provided on the chute plate 72, and the sliding shaft 73 is slidably connected to the parallelogram chute of the chute plate 72. A sealing plate 79 is connected to the connecting rod 74 and is in sliding contact with the bottom inner wall of the air box 3. The inner wall of the end of the air-blocking plate 76 away from the sliding seat 75 is connected through a limiting shaft 77. Two limiting grooves 78 are respectively provided on the top inner wall and the bottom inner wall of the air box 3. The top ends of the two limiting shafts 77 are slidably connected to the upper two limiting grooves 78, and the bottom ends of the two limiting shafts 77 are slidably connected to the lower two limiting grooves 78; an exhaust port is provided on the intake housing 1 below the slide plate 71 to keep the air pressure in the space below the slide plate 71 consistent with the outside. An accordion rubber strip is provided at the top edge on the right side of the slide plate 71 to seal between the top on the right side of the slide plate 71 and the bottom of the air box 3. A space is formed between the space above the slide plate 71 in the intake housing 1 and the inside of the air box 3, and another space is formed in the space below the slide plate 71 in the intake housing 1. The two spaces are isolated from each other. When the exhaust gas pressure in the intake pipe 10 is weak, the exhaust gas with a lower flow rate gradually accumulates in the space above the slide plate 71. When the exhaust gas above the slide plate 71 accumulates to squeeze the slide plate 71 to the lowest position, the two air-blocking plates 76 open the air duct. The exhaust gas above the slide plate 71 is squeezed by the elastic force of the plurality of springs at the bottom of the slide plate 71, so that the flow rate of the exhaust gas increases and enters the separation pipe 4 through the air box 3. When there is not much exhaust gas left above the slide plate 71, the slide plate 71 returns to the uppermost position, and the two air-blocking plates 76 close the air duct to accumulate the next batch of exhaust gas; through the setting of the supercharging component 7, the exhaust gas with a lower flow rate accumulates in the space between the intake housing 1 and the top of the slide plate 71. When the exhaust gas accumulates to a certain amount, it is pushed by the slide plate 71 and enters the subsequent purification process, improving the flow rate of the exhaust gas, thereby enhancing the centrifugal force generated by the exhaust gas in the separation pipe 4, and thus improving the efficiency of solid particle separation;On the top surface of the skateboard 71, there are two mounting grooves 710. A slider 713 is slidably connected in the mounting groove 710. The tops of the two sliders 713 are connected with a scraping strip 712. A connecting rod 711 is hinged on the scraping strip 712. One end of the connecting rod 711 away from the scraping strip 712 is hinged to the left inner wall of the air intake housing 1. The scraping strip 712 is in sliding contact with the top surface of the skateboard 71. When the skateboard 71 slides upward, the connecting rod 711 drives the scraping strip 712 to slide to the right, so that the scraping strip 712 shovels the solid particles attached to the surface of the skateboard 71 to the left, enabling the solid particles to enter the air box 3 along with the airflow, preventing the solid particles from accumulating on the skateboard 71. The bottom of the slider 713 is connected with a first sawtooth rack 714, and a second sawtooth rack 715 is connected in the mounting groove 710. The two first sawtooth racks 714 are respectively in contact with the two second sawtooth racks 715. When the slider 713 slides, vibrations are generated through the cooperation between the first sawtooth rack 714 and the second sawtooth rack 715. The two sliders 713 drive the scraping strip 712 to vibrate, so that the scraping strip 712 can vibrate itself while shoveling the solid particles, enhancing the shoveling effect. Through the arrangement of the scraping strip 712, when the waste gas enters the air box 3, the scraping strip 712 shovels the solid particles on the surface of the skateboard 71 towards the air box 3, enabling the deposited solid particles to enter the air box 3 for subsequent separation, preventing the surface of the skateboard 71 from depositing too many solid particles after long-term use and affecting the use effect.

[0023] Furthermore, please refer to Figure 2 , Figure 8 - Figure 11, a scraping wall assembly 8, which is used to facilitate the dropping of waste residue in the separation tube 4. The scraping wall assembly 8 includes a sliding rod 81. The sliding rod 81 is connected to the right side of the sliding seat 75 through a bracket. A circular hole is provided in the central part of the impeller 41. The sliding rod 81 is slidably connected through the circular hole of the impeller 41. An annular inclined groove 84 is provided on the outer surface of the end of the sliding rod 81 away from the sliding seat 75. Two rotating rings 82 are rotatably connected to the inner wall of the separation tube 4. A plurality of scraping bars 85 are connected between the two rotating rings 82. A ball ring 83 is connected to the left rotating ring 82 through a bracket. The inner wall of the ball ring 83 is slidably connected to the annular inclined groove 84 through balls. When the sliding rod 81 moves left and right, it can drive the ball ring 83 to rotate by a certain angle through the annular inclined groove 84. When the ball ring 83 rotates, it drives the two rotating rings 82 and a plurality of scraping bars 85 to rotate synchronously. A plurality of scraping bars 85 are all in sliding contact with the inner wall of the separation tube 4. A plurality of scraping bars 85 are all located above the square tube 42. When the plurality of scraping bars 85 rotate, they can scrape the inner wall of the separation tube 4, so that the solid particles attached to the inner wall of the separation tube 4 fall into the square tube 42, avoiding that after long-term use, more solid particles adhere to the inner wall of the separation tube 4 and reduce the effective space in the separation tube 4; A crowbar 86 is rotatably installed on the inner wall of the gas collecting pipe 5. The left end of the crowbar 86 is set as an upward bent section. The right end of the crowbar 86 is provided with an arc section. Two dial shafts 87 are connected to the end of the sliding rod 81 away from the sliding seat 75 through a bracket. The bent section of the crowbar 86 is located between the two dial shafts 87. An installation shaft 88 is slidably connected through the inner wall of the umbrella plate separator 61. The arc section of the crowbar 86 is in sliding contact with the bottom of the installation shaft 88. When the two dial shafts 87 move leftward, the left end of the crowbar 86 is pushed downward through the bent section of the crowbar 86, so that the right end of the crowbar 86 moves upward. The arc section at the right end of the crowbar 86 pushes the installation shaft 88 upward. The top of the installation shaft 88 is connected with a plurality of hole cleaning bars 89. A plurality of hole cleaning bars 89 are all located above the umbrella plate separator 61. A plurality of through holes are provided on the umbrella plate separator 61. The bottom of the hole cleaning bars 89 is provided with a plurality of dredging bristles. When the plurality of dredging bristles on the plurality of hole cleaning bars 89 move, they respectively enter the plurality of through holes of the umbrella plate separator 61. The plurality of dredging bristles on the plurality of hole cleaning bars 89 are respectively inserted into the plurality of through holes of the umbrella plate separator 61. Since there are still some smaller solid particles in the waste gas contacted by the umbrella plate separator 61, the through holes of the umbrella plate separator 61 may be blocked by the accumulated solid particles after long-term use. After the dredging bristles are inserted into the through holes, they can dredge the through holes and push the solid particles attached to the through holes to fall, maintaining the effective area of the through holes; Through the setting of the scraping wall assembly 8, a plurality of scraping bars 85 can intermittently scrape the inner wall of the separation tube 4, so that the solid particles attached to the inner wall of the separation tube 4 fall off, avoiding the accumulation of solid particles on the inner wall of the separation tube 4 and thus affecting the use effect;Through the arrangement of multiple hole cleaning bars 89, the multiple hole cleaning bars 89 fall onto the umbrella plate separator 61 after the separation operation in one stage, enabling the multiple dredging bristles to dredge the through holes of the umbrella plate separator 61 and maintaining the service effect of the umbrella plate separator 61. When starting the separation operation, the mounting shaft 88 drives the multiple hole cleaning bars 89 to move upward, without affecting the normal operation of the umbrella plate separator 61.;

[0024] Furthermore, please refer to Figure 2 , Figure 12 - Figure 14, a vibration assembly 9, which is used to prevent waste residue from accumulating on the surface of the screen 21. The vibration assembly 9 includes a rotating shaft 91, which is rotatably installed through the inner walls between the air inlet housing 1 and the separation housing 2. A gear 92 is connected to the outer wall of the rotating shaft 91. A toothed bar 93 is connected to the bottom of the slide plate 71. The toothed bar 93 meshes with the gear 92 during movement. When the toothed bar 93 moves up and down, it meshes with the gear 92 and drives the rotating shaft 91 to rotate through the gear 92. An elliptical wheel 94 is connected to the outer wall of the rotating shaft 91. The top of the screen 21 is rotatably connected to the inner wall of the separation housing 2. A supporting rod is provided on the inner wall of the separation housing 2. The bottom of the screen 21 is lapped on the supporting rod inside the separation housing 2. A resisting rod 95 is connected to the bottom of the screen 21. The outer wall of the elliptical wheel 94 is in sliding contact with the resisting rod 95. When the elliptical wheel 94 rotates, it drives the bottom of the screen 21 to continuously move up and down through the resisting rod 95, so that the bottom of the screen 21 continuously detaches from the supporting rod and then laps on the supporting rod again, thereby achieving the effect that the screen 21 can vibrate. The screen 21 can promote the sliding of the waste residue above it through vibration, and avoid the situation of material accumulation and blockage on the surface of the screen 21; A cam 96 is connected to the outer wall of the rotating shaft 91. A sliding frame 97 is slidably installed inside the waste residue box 22. Two dial rods 98 are connected to the sliding frame 97. A part of the cam 96 is located between the two dial rods 98. When the cam 96 moves, it contacts the two dial rods 98. Two right-angle rods 99 are connected to the bottom of the sliding frame 97. Two metal wires 910 are connected between the two right-angle rods 99. The two metal wires 910 are located below the bottom of the screen 21. When the cam 96 rotates, it drives the sliding frame 97 to slide left and right through the two dial rods 98. The sliding frame 97 drives the two metal wires 910 to slide left and right through the two right-angle rods 99. Since the position in the waste residue box 22 at the bottom of the screen 21 is the falling point of the waste residue, the waste residue here accumulates first. When the waste residue accumulates to a certain height, the two metal wires 910 push the accumulated waste residue to both sides through left and right movement, making the accumulation of the waste residue more uniform; Through the setting of the vibration assembly 9, the elliptical wheel 94 can drive the screen 21 to vibrate through the resisting rod 95, thereby promoting the falling of the waste residue on the surface of the screen 21 and avoiding the situation of material accumulation and blockage on the screen 21; Through the setting of the two metal wires 910, the two metal wires 910 push the waste residue with a relatively high accumulation to both sides through left and right movement, making the accumulation of the waste residue in the waste residue box 22 more uniform and avoiding the situation of local excessive accumulation.

[0025] With the above structure, the working principle of this case is that the exhaust gas enters the air intake housing 1 through the air intake pipe 10. At this time, the two wind blocking plates 76 block the air duct of the bellows 3, and the exhaust gas in the air intake housing 1 gradually increases, causing the air pressure in the air intake housing 1 to rise. A partition is provided in the air intake housing 1 to separate the space at the bottom of the slide plate 71 separately. An exhaust port is provided on the air intake housing 1 below the slide plate 71, so that the air pressure in the space below the slide plate 71 is kept consistent with the outside world. An accordion rubber strip is provided on the right top edge of the slide plate 71 to seal the right top of the slide plate 71 and the bottom of the bellows 3. Therefore, the air pressure above the slide plate 71 is higher than that below the slide plate 71, so that the exhaust gas squeezes the slide plate 71 downward, and the slide plate 71 moves downward. When the sliding shaft 73 slides to the hypotenuse at the bottom of the parallelogram sliding groove, the sliding shaft 73 pushes the sliding groove plate 72 to the left through the hypotenuse, so that the sliding groove plate 72 pushes the sliding seat 75 to the left through the connecting rod 74. When the sliding seat 75 moves to the left, it drives the connection between the two air blocking plates 76 and the sliding seat 75 to move to the left. At this time, the limiting shaft 77 of the air blocking plate 76 slides between the two limiting grooves 78 toward the middle of the air box 3, so that the gaps between the two sides of the two air blocking plates 76 and the inner wall of the air box 3 are opened. At this time, the air duct in the air box 3 is opened, and the exhaust gas above the slide plate 71 enters the separation pipe 4 through the air box 3. The elastic force of multiple springs at the bottom of the slide plate 71 causes the slide plate 71 to squeeze the exhaust gas above it into the bellows 3, thereby increasing the flow rate of the exhaust gas in the bellows 3. At the same time, the slide shaft 73 slides upward along the right straight side of the parallelogram slide slot. When the slide shaft 73 slides to the upper oblique side of the parallelogram slide slot, the slide shaft 73 pushes the slide slot plate 72 to the right through the oblique side, so that the slide slot plate 72 is reset, so that the slide seat 75 and the two wind blocking plates 76 are also reset, and the air duct in the bellows 3 is closed again. When the connecting rod 74 moves, the sealing plate 79 seals the connection between the connecting rod 74 and the bellows 3 to maintain the sealing between the bellows 3. Through the arrangement of the partition plate, the accordion rubber strip and the sealing plate 79, the intake air is A space is formed between the space above the slide plate 71 in the housing 1 and the interior of the bellows 3, and another space is formed between the space below the slide plate 71 in the air intake housing 1. The two spaces are isolated from each other. When the exhaust gas pressure in the air intake pipe 10 is weak, the exhaust gas with a lower flow rate gradually accumulates in the space above the slide plate 71. When the exhaust gas above the slide plate 71 accumulates to the point where the slide plate 71 is squeezed to the bottom, the two air blocking plates 76 open the air duct, and the elastic force of multiple springs at the bottom of the slide plate 71 squeezes the exhaust gas above the slide plate 71, thereby increasing the flow rate of the exhaust gas and entering the separation pipe 4 through the bellows 3. When there is little exhaust gas above the slide plate 71, the slide plate 71 returns to the top, and the two air blocking plates 76 close the air duct to accumulate the next batch of exhaust gas.While the skateboard 71 slides downward, the cooperation of the two mounting grooves 710 and the two sliders 713 drives the scraping bar 712 to move downward. At the same time, the connecting rod 711 drives the scraping bar 712 to slide to the left. When the skateboard 71 slides upward, the connecting rod 711 drives the scraping bar 712 to slide to the right, so that the scraping bar 712 shovels the solid particles attached to the surface of the skateboard 71 to the left, and the solid particles follow the airflow into the air box 3, preventing the solid particles from accumulating on the skateboard 71. When the slider 713 slides, vibration is generated through the cooperation between the first sawtooth rack 714 and the second sawtooth rack 715. The two sliders 713 drive the scraping bar 712 to vibrate, so that the scraping bar 712 can vibrate itself while shoveling the solid particles to enhance the shoveling effect; through the setting of the pressurizing assembly 7, the exhaust gas with a relatively low flow rate accumulates in the space between the intake housing 1 and the top of the skateboard 71. When the exhaust gas accumulates to a certain amount, it is pushed by the skateboard 71 and enters the subsequent purification process, improving the flow rate of the exhaust gas, thereby enhancing the centrifugal force generated by the exhaust gas in the separation tube 4, and thus improving the efficiency of solid particle separation; through the setting of the scraping bar 712, when the exhaust gas enters the air box 3, the scraping bar 712 shovels the solid particles on the surface of the skateboard 71 towards the air box 3, so that the deposited solid particles enter the air box 3 for subsequent separation, preventing the surface of the skateboard 71 from depositing too many solid particles after long-term use and affecting the use effect.

[0026] After the exhaust gas enters the separation tube 4, a vortex is formed through the diversion of the impeller 41, generating a certain centrifugal force, so that the solid particles in the exhaust gas are carried to the inner wall of the separation tube 4 by the centrifugal force. The exhaust gas at the center of the vortex enters the recovery tube 6 through the gas collecting pipe 5. Subsequently, the exhaust gas flows upward. The umbrella plate separator 61 in the recovery tube 6 is used to separate the larger water droplets in the exhaust gas, and the wire mesh demister 62 is used to separate the smaller water droplets in the exhaust gas. The exhaust gas from which solids and liquids are separated is transported to the next process through the outlet pipe 11. The water droplets separated by the umbrella plate separator 61 and the wire mesh demister 62 fall onto the lower screen 21. The solid particles in the separation tube 4 also fall onto the screen 21 through the square tube 42. The liquid passes through the screen 21 and falls into the waste liquid tank 23. The solids remain on the screen 21 and slide down along the inclined surface of the screen 21 into the waste residue box 22, separating the waste liquid and the waste residue for separate collection; through the cooperation of the screen 21, the waste residue box 22, and the waste liquid tank 23, the waste residue box 22 and the waste liquid tank 23 can store the solid waste and liquid waste separated from the exhaust gas separately, preventing chemical reactions between the solid waste and the liquid waste.

[0027] When the sliding seat 75 moves, it drives the sliding rod 81 to move synchronously through the bracket. When the sliding rod 81 moves left and right, it can drive the ball ring 83 to rotate at a certain angle through the annular inclined groove 84. The ball ring 83 drives the rotating ring 82 connected to it to rotate synchronously through the bracket. The rotating ring 82 drives another rotating ring 82 to rotate synchronously through a plurality of scraping strips 85. When the plurality of scraping strips 85 rotate, they can scrape the inner wall of the separation tube 4, so that the solid particles attached to the inner wall of the separation tube 4 fall into the square tube 42, avoiding that after long-term use, more solid particles are attached to the inner wall of the separation tube 4 and the effective space inside the separation tube 4 is reduced; when the sliding rod 81 moves left and right, it drives the two shifting shafts 87 to move left and right synchronously. When the two shifting shafts 87 move left, the bent section of the lever 86 is used to push the left end of the lever 86 downward, so that the right end of the lever 86 moves upward. The arc section at the right end of the lever 86 pushes the mounting shaft 88 upward, so that the mounting shaft 88 drives a plurality of hole-clearing strips 89 to move upward. When the sliding seat 75 and the sliding rod 81 move left, it is the intake of the separation tube 4. At this time, after the plurality of hole-clearing strips 89 move upward, the dredging bristles of the plurality of hole-clearing strips 89 do not contact the umbrella plate separator 61, and the umbrella plate separator 61 operates normally. When the sliding seat 75 and the sliding rod 81 move right, it is the stop of the intake of the separation tube 4. At this time, the two shifting shafts 87 are pushed upward through the bent section of the lever 86 to reset the lever 86, and the mounting shaft 88 is reset by gravity. The plurality of dredging bristles on the plurality of hole-clearing strips 89 are respectively inserted into the plurality of through holes of the umbrella plate separator 61. Since there are still some smaller solid particles in the waste gas contacted by the umbrella plate separator 61, the through holes of the umbrella plate separator 61 may be blocked by the accumulated solid particles after long-term use. After the dredging bristles are inserted into the through holes, they can dredge the through holes and push the solid particles attached to the through holes to fall, maintaining the effective area of the through holes; through the setting of the scraping wall assembly 8, the plurality of scraping strips 85 can intermittently scrape the inner wall of the separation tube 4, so that the solid particles attached to the inner wall of the separation tube 4 fall off, avoiding the accumulation of solid particles on the inner wall of the separation tube 4 and thus affecting the use effect; through the setting of the plurality of hole-clearing strips 89, the plurality of hole-clearing strips 89 fall onto the umbrella plate separator 61 after a stage of separation operation, so that the plurality of dredging bristles dredge the through holes of the umbrella plate separator 61 and maintain the use effect of the umbrella plate separator 61. When starting the separation operation, the mounting shaft 88 drives the plurality of hole-clearing strips 89 to move upward, which does not affect the normal operation of the umbrella plate separator 61.

[0028] When the skateboard 71 moves up and down, it drives the toothed bar 93 to move up and down synchronously. During the up and down movement of the toothed bar 93, it meshes with the gear 92 and drives the rotating shaft 91 to rotate through the gear 92. The rotating shaft 91 penetrates through the intake housing 1 and the separation housing 2, and the connection positions of the rotating shaft 91 with the intake housing 1 and the separation housing 2 are sealed. When the rotating shaft 91 rotates, it drives the elliptical wheel 94 to rotate. When the elliptical wheel 94 rotates, it drives the bottom of the screen 21 to continuously shake up and down through the contact rod 95, so that the bottom of the screen 21 continuously detaches from the supporting rod and then rests on the supporting rod again, thus achieving the effect that the screen 21 can shake. The screen 21 can promote the sliding down of the waste residue above it through shaking, and avoid the situation of material accumulation and blockage on the surface of the screen 21; when the rotating shaft 91 rotates, it drives the inclined wheel 96 to rotate. When the inclined wheel 96 rotates, it drives the sliding frame 97 to slide left and right through the two shift rods 98. The sliding frame 97 drives the two metal wires 910 to slide left and right through the two right-angle rods 99. Since the position at the bottom of the screen 21 in the waste residue box 22 is the waste residue falling point, the waste residue here accumulates first. When the waste residue accumulates to a certain height, the two metal wires 910 move the accumulated waste residue to both sides through left and right movement, making the accumulation of the waste residue more uniform; through the setting of the vibration assembly 9, the elliptical wheel 94 can drive the screen 21 to shake through the contact rod 95, thereby promoting the falling of the waste residue on the surface of the screen 21 and avoiding the situation of material accumulation and blockage on the screen 21; through the setting of the two metal wires 910, the two metal wires 910 move the waste residue with a relatively high accumulation to both sides through left and right movement, making the accumulation of the waste residue in the waste residue box 22 more uniform and avoiding the situation of local over-accumulation.

Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
