Description

Technical Field

[0001] The invention relates to the technical field of dust treatment, and in particular to a dust collection device for rare earth oxide treatment. Background Art

[0002] Rare earth oxides refer to compounds generated by the reaction of rare earth elements with oxygen, such as cerium oxide, lanthanum oxide, neodymium oxide and samarium oxide. Due to their good electrical and thermal conductivity, rare earth oxides are widely used in catalysts, glass and ceramics. In the process of rare earth oxide processing, especially in the drying and grinding stages, a large amount of dust may be generated. Considering the relative scarcity of rare earth element resources, these dusts may contain rare earth oxides that are not fully utilized. Therefore, these dusts can be effectively collected and reprocessed to achieve resource recycling. At present, bag dust removal devices are usually used for dust removal.

[0003] Existing dust collection devices, such as the Chinese patent with announcement number CN219539730U, disclose a dust collection device. Although the L-shaped scraper installed on the bottom surface of the gear ring and the scraper rod can scrape off the dust attached to the inner wall of the dust collecting tank and the surface of the dust bag, thereby preventing dust accumulation inside the dust collecting tank and on the surface of the dust bag, the bag is usually made of flexible materials. If there is no support structure inside the bag, the scraping effect of the scraper rod may be limited. Secondly, if water is used or moisture is generated during the processing of rare earth oxides, it may cause residual moisture in the dust, thereby increasing the adhesion between the dust and the bag, and then the wet dust is more likely to adhere to the bag and form agglomerates, thereby hindering the passage of airflow and reducing the filtration efficiency. The scraper rod can only scrape off the agglomerated dust, and cannot collect the relatively wet dust stuck on the bag.

DETAILED DESCRIPTION

[0026] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0027] A dust collection device for rare earth oxide processing, such as Figure 1-Figure 9As shown, it includes a mounting frame 101, and the mounting frame 101 includes universal wheels. The universal wheels are installed on the bottom surface of the mounting frame 101, which is convenient for adjustment and use at different positions to increase the flexibility of the equipment.

The left side of the processing box 102 is sealed and connected with the inspection pipe. The inspection pipe can facilitate operators to enter the interior of the processing box 102. The front part of the processing box 102 is provided with an observation window and a control box 105. The observation window can facilitate operators to observe the specific situation inside the processing box 102 in real time. The control box 105 can control all electrical components of the device. The right side of the processing box 102 is sealed and connected with a feed pipe 103, and the feed pipe 103 is connected to the outside dust The suction device is connected, the lower part of the processing box 102 is connected with a discharge pipe 104, and the discharge pipe 104 includes a control valve arranged on the discharge pipe 104, so that the discharge of dust can be quickly started or stopped, and the operator can accurately adjust the discharge amount of dust. Four cloth bags 201 are distributed inside the processing box 102, and the four cloth bags 201 are symmetrically arranged. Four movable covers 301 are evenly distributed and detachably connected on the upper part of the processing box 102. A first fixed cover 302 is fixedly connected to the middle part of the movable cover 301, and a through hole for ventilation is arranged on the first fixed cover 302. A second fixed cover 303 is arranged directly below the first fixed cover 302, and a first rotating shaft 304 is rotatably connected between the first fixed cover 302 and the second fixed cover 303. The movable cover 3 01 is provided with a clamping component for clamping the opening of the cloth bag 201, wherein the top surface of the first fixed cover 302 is flush with the top surface of the cloth bag 201, and the bottom surface of the second fixed cover 303 is flush with the bottom surface inside the cloth bag 201, so that the cloth bag 201 is in a straight state after installation, and the first rotating shaft 304 is connected with an agitating component for agitating the cloth bag 201, and the outside of the cloth bag 201 is also provided with a scrubbing component for scrubbing the cloth bag 201, the top of the movable cover 301 is connected with a connecting seat 202, and the upper part of the connecting seat 202 is connected with an air duct 203, and an air duct fan 204 for guiding the flow of gas is installed inside the air duct 203, and an exhaust pipe 205 is arranged above the air duct 203, and the exhaust pipe 205 is connected with the four air ducts 203, and the exhaust pipe A flow monitoring valve 206 is installed at the top of 205. It can be seen that when installing the cloth bag 201 (the cloth bag 201 is an open flat-bottom style), the operator can insert the second fixed cover 303, the first rotating shaft 304, and the first fixed cover 302 into the cloth bag 201 from bottom to top in sequence through the inspection pipe inside the processing box 102, so that the top surface of the cloth bag 201 is flush with the top surface of the first fixed cover 302, and then clamp the cloth bag 201 through the clamping component to make the cloth bag 201 in a straight state, which can reduce the wrinkles of the cloth bag 201 and increase the filtering area. Then, the dust and air are sucked into the feeding pipe 103 through the external dust suction device, and the induced draft fan 204 is started to guide the flow of dust and air, so that the cloth bag 201 filters the dust on the outer wall.The air flows into the bag 201, then flows into the exhaust pipe 205 through the duct 203, and finally is discharged from the exhaust pipe 205. The air is agitated from the bag 201 by the agitation component, so that the dust on the outer wall of the bag 201 falls to the bottom of the processing box 102, and finally the dust is discharged and collected through the discharge pipe 104. When there is moisture in the air, wet dust will adhere to the outer wall of the bag 201, and it is difficult to fall off even if it is agitated. At this time, the outer wall of the bag 201 can be scrubbed by the scrubbing component to loosen the wet dust attached to the outer wall of the bag 201 and finally fall off. In this way, the dust with strong stickiness can be effectively removed, the outer wall of the bag 201 is ensured to be clean, and the filtering efficiency of the bag 201 is improved.

[0028] Specifically, in order to make it more convenient to replace the cloth bag 201, the clamping component includes four electromagnets 601 evenly distributed and slidably connected to the movable cover 301, and a first elastic member 602 is provided between the electromagnet 601 and the movable cover 301. The first elastic member 602 is a spring. It can be seen that when working, the operator enters the interior of the processing box 102 through the inspection pipe, and then sequentially puts the second fixed cover 303, the first rotating shaft 304, and the first fixed cover 302 into the cloth bag 201 from bottom to top, and then starts the electromagnet 601 through the control box 105, and then the electromagnet 601 is electrically The magnet 601 is magnetic and is magnetically connected to the first fixed cover 302, so that the electromagnet 601 slides on the movable cover 301, so that the first elastic member 602 is stretched, so that the cloth bag 201 sleeved between the first fixed cover 302 and the electromagnet 601 is fixed, so that the cloth bag 201 is installed inside the processing box 102. When replacing the old cloth bag 201, the electromagnet 601 is turned off through the control box 105, and then the first elastic member 602 is reset to drive the electromagnet 601, so that the old cloth bag 201 can be removed, and the replacement method is simple and convenient.

[0029] Furthermore, in order to collect dust more conveniently, the agitation assembly includes a first movable frame 401 slidably connected to the first rotating shaft 304, the first movable frame 401 moves up and down through a first linear module, the first movable frame 401 is slidably connected to a first agitation block 402 and a second agitation block 404, both the first agitation block 402 and the second agitation block 404 are provided with a toothed structure, the middle part of the first movable frame 401 is rotatably connected to a first gear 403, the first gear 403 is meshed with the first agitation block 402 and the second agitation block 404 at the same time, the first rotating shaft 304 is provided with a first keyway, and the center of the first gear 403 is provided with a first sliding key that matches the first keyway, so that the first gear 403 can slide on the first rotating shaft 304 , and will rotate with the rotation of the first rotating shaft 304. The first rotating shaft 304 is rotated by the first driving component. Specifically, the first linear module includes a screw rod 411, a first motor 412, a first synchronous belt component 413 and a rotating shaft 414. The top surface of the second fixed cover 303 is rotatably connected with the screw rod 411. The screw rod 411 penetrates the first fixed cover 302 and extends to the top of the first fixed cover 302. The screw rod 411 is threadedly connected to the first movable frame 401. The center of the top surface of the processing box 102 is rotatably connected with the rotating shaft 414. The top surface of the processing box 102 is installed with a first motor 412. The output shaft of the first motor 412 is fixedly connected to the rotating shaft 414. The rotating shaft 414 and the screw rod 411 are connected by the first synchronous belt component 413. The four first synchronous belt components 413 are connected to the rotating shaft 414 in a staggered manner, so that the four first movable frames 401 can operate synchronously. At the same time, the first synchronous belt component 413 is sealed and connected to the connecting seat 202 to prevent gas leakage. The first driving component includes a servo motor 421 and a second synchronous belt component 422. The servo motor 421 is installed on the connecting seat 202. The output shaft of the servo motor 421 and the first rotating shaft 304 are transmitted through the second synchronous belt component 422. The second synchronous belt component 422 has the effect of transmitting the power of the servo motor 421. In other embodiments, the second synchronous belt component 422 can be replaced with a gear set, and the effect is consistent with the second synchronous belt component 422. It can be seen that when working, the servo motor 421 is started. 21, and then the output shaft of the servo motor 421 drives the first rotating shaft 304 to rotate through the second synchronous belt component 422, and then the first rotating shaft 304 drives the first gear 403 to rotate, and the first gear 403 drives the first agitation block 402 and the second agitation block 404 to extend toward the inner wall of the cloth bag 201 through meshing transmission, and then the outer walls of the first agitation block 402 and the second agitation block 404 touch the inner wall of the cloth bag 201, and then the output shaft of the servo motor 421 rotates in the opposite direction, so that the first agitation block 402 and the second agitation block 404 move in the opposite direction, so that the first agitation block 402 and the second agitation block 404 continuously touch the inner wall of the cloth bag 201, so that the cloth bag 201 is shaken, and the dust on the outer wall of the cloth bag 201 can be shaken off,In this way, the dust on the outer wall of the bag 201 can be effectively collected, and the outer wall of the bag 201 can be kept clean, the air circulation can be maintained, and the dust removal efficiency of the bag 201 can be ensured. While shaking, the first motor 412 is started, and then the output shaft of the first motor 412 drives the rotating shaft 414 to rotate, and the rotating shaft 414 drives the four screw rods 411 to rotate through the first synchronous belt component 413. The rotation of the screw rods 411 causes the first movable frame 401 to move up and down, thereby expanding the agitation range of the first agitation block 402 and the second agitation block 404, so that the first agitation block 402 and the second agitation block 404 can relatively cover the entire inner wall of the bag 201.

[0030] Furthermore, when the air contains moisture, wet dust will adhere to the outer wall of the cloth bag 201, and the stickiness is strong, and it is difficult to fall off even if it is agitated. At this time, the outer wall of the cloth bag 201 can be scrubbed by the scrubbing component to loosen and fall off the dust attached to the outer wall of the cloth bag 201. The scrubbing component includes a second movable frame 501 arranged in the processing box 102, and the second movable frame 501 moves up and down through a second linear module. Four scrubbing blocks 502 for scrubbing the outer wall of the cloth bag 201 are distributed and rotatably connected in the second movable frame 501. The inner wall of the scrubbing block 502 abuts against the outer wall of the cloth bag 201, and the scrubbing block 502 is rotated by a second driving component. The scrubbing block 502 is made of soft rubber, which can avoid damaging the cloth bag 201 during scrubbing. A toothed structure is provided, and the second driving component includes two second gears 511 rotatably connected to the second movable frame 501, and the second gears 511 are meshed with the two scrubbing blocks 502 at the same time. A second rotating shaft 513 is rotatably connected to the processing box 102, and a second motor 512 is installed on the top of the processing box 102. The output shaft of the second motor 512 is fixedly connected to the second rotating shaft 513, and a second keyway is provided on the second rotating shaft 513. A second sliding key matching the keyway is provided at the center of the second gear 511, so that the second gear 511 can slide on the second rotating shaft 513 and rotate with the rotation of the second rotating shaft 513. Specifically, the second linear module uses a combination of a screw, a guide rod and a rotating motor, which is a prior art, and realizes the function of driving the second movable frame 501 to move up and down, so it is not elaborated in detail.

[0031] More specifically, the second agitation block 404 includes a straight rod 431, a movable block 432 and a micro electric push rod 433. The straight rod 431 is slidably connected to the first movable frame 401. A toothed structure is provided on the straight rod 431. The straight rod 431 meshes with the first gear 403. A micro electric push rod 433 is installed in the straight rod 431. The movable block 432 is fixed to the telescopic rod of the micro electric push rod 433. The movable block 432 and the first agitation block 402 are both semicircular on one side facing the inner wall of the cloth bag 201, and the movable block 432 and the first agitation block 402 can form a circle when combined, and the size is consistent with the inner wall of the cloth bag 201. It should be noted that when agitating, the movable block 432 is located above the first agitation block 402, and the vertical thickness of the movable block 432 and the first agitation block 402 is greater than or equal to the scrubbing block 502. The specific value needs to be adjusted according to actual conditions.

[0032] It can be seen that during operation, when the flow monitoring valve 206 monitors that the exhaust air flow rate is lower than the preset value, it means that the outer wall of the bag 201 is stained with dust with strong stickiness. At this time, the servo motor 421 is started, and then the output shaft of the servo motor 421 drives the first rotating shaft 304 to rotate through the second synchronous belt component 422, and then the first rotating shaft 304 drives the first gear 403 to rotate, and the first gear 403 drives the first agitation block 402 and the second agitation block 404 to extend toward the inner wall of the bag 201 through meshing transmission. When the first agitation block 402 and the second agitation block When the outer wall of 404 touches the inner wall of the cloth bag 201, the servo motor 421 is turned off, so that the first agitation block 402 and the second agitation block 404 support the cloth bag 201 from the inside, and then the micro electric push rod 433 is started, and the telescopic rod of the micro electric push rod 433 retracts, so that the movable block 432 moves downward, so that the outer wall of the movable block 432 and the first agitation block 402 forms a circle, so that the shape of the cloth bag 201 is stabilized in a circle, so that the scrubbing block 502 can cover the entire outer wall of the cloth bag 201 to prevent cleaning dead corners. Then, the first motor 412 is started to reset the first movable frame 401, and at the same time, the first agitating block 402 and the second agitating block 404 are aligned with the scrubbing block 502, and then the second motor 512 is started, and then the output shaft of the second motor 512 drives the second rotating shaft 513 to rotate, and then the second rotating shaft 513 drives the second gear 511 to rotate, and the second gear 511 drives the scrubbing block 502 to rotate through meshing transmission. In this process, the first agitating block 402 and the second agitating block 404 support the cloth bag 201 from the inside to ensure that the scrubbing block 502 is in the scrubbing state. The cloth bag 201 can obtain effective supporting force, so the cooperation between the scrubbing block 502 and the first agitating block 402 and the second agitating block 404 can loosen the attached wet dust, and then the first motor 412 and the second linear module are started at the same time, and then the output shaft of the first motor 412 rotates to make the first movable frame 401 move up and down, and the second linear module drives the second movable frame 501 to move up and down synchronously with the first movable frame 401, thereby expanding the scrubbing range of the scrubbing block 502, so that the scrubbing block 502 can relatively cover the entire outer wall of the cloth bag 201.

[0033] Furthermore, in order to prevent the agglomerated and relatively hard dust from obstructing the operation of the scrubbing block 502, a scraper 701 is fixedly connected to the bottom surface of the scrubbing block 502, and the inner wall of the scraper 701 slightly contacts the outer wall of the cloth bag 201. It can be seen that during operation, when the scrubbing block 502 moves, the scraper 701 will scrape off the hard dust on the outer wall of the cloth bag 201, thereby preventing the hard dust from obstructing the operation of the scrubbing block 502.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
