Description

Technical Field

[0001] This invention belongs to the field of dust removal equipment technology, specifically a dust adsorption and purification device for wire production. Background Technology

[0002] Wire production refers to the entire process of drawing and stranding metal conductors into wire cores, then covering them with insulation and sheath layers, and finally producing wire products that have conductive functions and meet safety performance standards through a series of processes such as shielding, cabling, and testing. Wires are mainly used in fields such as power transmission, electrical equipment connection, and building wiring.

[0003] The production of electrical wires generates a large amount of dust during conductor drawing, insulation extrusion, and sheath processing. By using a fan to generate negative pressure, dust-laden gas can be drawn into the dust adsorption and purification equipment. Through core processes such as filter interception, electrostatic adsorption, or activated carbon adsorption, the dust is separated from the air, and the purified gas is discharged in compliance with standards.

[0004] In some existing technologies, bag filters are used to purify dusty exhaust gas generated during wire production. The bag filter is equipped with multiple sets of dust collection bags to adsorb dust. However, in some existing technologies, some dust may still adhere to the inner wall of the bag filter due to static electricity or light weight. After adsorption stops, the operator needs to clean it manually, which is inconvenient. Therefore, a dust adsorption and purification device for wire production is proposed to address the above problems. Summary of the Invention

[0007] Preferably, the outer wall of the rotating rod is provided with a groove, the connecting rod is hinged to the outer wall of the moving rod through a hinge rod, and the motor is fixedly connected to the top outer wall of the housing.

[0008] Preferably, the rotating rod is rotatably connected to the inner wall of the top of the housing, the movable end of the guide telescopic rod is fixedly connected to the outer wall of the scraper, and the protrusion is engaged with the groove.

[0009] Preferably, one end of the connecting spring is fixedly connected to the outer wall of the protrusion, the other end of the connecting spring is fixedly connected to the inner wall of the moving rod, and the protrusion is slidably connected to the inner wall of the moving rod.

[0010] Preferably, the two ends of the connecting rod are respectively hinged to the outer walls of the scraper and the rotating rod, and the two ends of the hinged rod are respectively hinged to the outer walls of the scraper and the moving rod.

[0011] Preferably, the sealing mechanism includes a connecting block A, a sealing airbag fixedly connected to the inner wall of the connecting block A, an air cylinder connected to the outer wall of the sealing airbag via an air supply pipe, a valve provided on the inner wall of the air supply pipe, a pressure plate elastically connected to the inner wall of the air cylinder via a return spring, a rotating wheel rotatably connected to the inner wall of the connecting block A, a pull rope wound around the outer wall of the rotating wheel, a movable plate slidably connected to the inner wall of the connecting block A, and a connecting block B provided on the outer wall of the air collection pipe via a limiting component, with a square groove formed on the inner wall of the connecting block B.

[0012] Preferably, the connecting block A is fixedly connected to the outer wall of the housing, one end of the return spring is fixedly connected to the outer wall of the pressure plate, the other end of the return spring is fixedly connected to the inner wall of the air cylinder, and the pressure plate is slidably connected to the inner wall of the air cylinder.

[0013] Preferably, the two ends of the pull rope are fixedly connected to the outer walls of the moving plate and the pressure plate, respectively, the connecting block B is in contact with the outer wall of the connecting block A, and the connecting block B is in contact with the outer wall of the moving plate.

[0014] Preferably, the limiting component includes a rotating ring, the outer wall of which has an inclined groove, the inner wall of the connecting block A is slidably connected to a sliding rod, and the inner wall of the connecting block A is elastically connected to a square block by a telescopic spring.

Under the guidance of the guide telescopic rod, the scraper moves to both sides while remaining vertical and fits against the inner wall of the housing. After starting the motor, the dust adhering to the inner wall of the housing can be cleaned. The scraper can also be retracted, preventing prolonged friction with the inner wall of the housing when cleaning is not required, thus reducing wear and extending service life. This invention, through the combination of a sealing airbag and a movable plate, allows the movable plate to be moved when the connecting block B is inserted into the connecting block A. The movable plate, through a pull rope, pulls the pressure plate to move, squeezing the gas into the sealing airbag. The sealing airbag provides a good sealing effect at the connection between the connecting block A and the connecting block B, preventing the leakage of dust-containing exhaust gas and pollution of the working environment. This invention utilizes a combination of a rotating ring and a square block. The rotating ring can be manually rotated to move the square block into the inner wall of the connecting block A. At this point, the connecting block A can be inserted into the connecting block B, and the connection and fixation are completed by the square block engaging with the square groove. This facilitates the disassembly and installation of the gas collection pipe without the need for rotating bolts, making it convenient and quick. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, the present invention provides a dust adsorption and purification device for wire production, including a housing 100, and further including: a rotating mechanism 200 disposed in the inner wall of the housing 100; and a gas collecting pipe 500 installed on the outer wall of the housing 100 through a sealing mechanism 300. The rotating mechanism 200 includes a motor 201, the output shaft of which is fixedly connected to a rotating rod 202. A moving rod 203 is slidably connected to the inner wall of the rotating rod 202. A scraper 205 is hinged to the outer wall of the rotating rod 202 via a connecting rod 204. A guide telescopic rod 206 is slidably connected to the outer wall of the rotating rod 202. A protrusion 209 is elastically connected to the inner wall of the moving rod 203 via a connecting spring 208. A dust collector bag 400 is fixedly connected to the outer wall of the rotating rod 202. A dust collection bag 600 is detachably installed on the bottom outer wall of the housing 100.

[0021] The above scheme employs the following: the housing 100 is the main body of a baghouse dust collector for dust treatment. Multiple sets of internal dust collection bags 400 adsorb smaller dust particles, while larger particles fall into the dust collection bag 600 due to inertia. The dust collection bag 600 can be removed for cleaning. Dust-laden exhaust gas from the wire manufacturing process is drawn into the housing 100 through the gas collection pipe 500. After adsorption and purification, the gas is discharged from the exhaust port at the rear end of the housing 100. The rotating mechanism 200 can... The rotating rod 202 drives multiple sets of dust collector bags 400 to rotate continuously, so that the multiple sets of dust collector bags 400 are aligned with the air inlet position at the connection between the air collecting pipe 500 and the outer wall of the housing 100 in turn. This avoids the problem of a set of dust collector bags 400 adsorbing too much dust for a long time due to the dust being not fixed, which would affect the adsorption effect due to dust overload. In addition, the rotating mechanism 200 can unfold the scraper 205 to scrape off the dust attached to the inner wall of the housing 100, which eliminates the need for operators to manually clean the dust on the inner wall, making it more convenient.

[0022] like Figures 2 to 4 As shown, the outer wall of the rotating rod 202 has a groove 210. The connecting rod 204 is hinged to the outer wall of the moving rod 203 via the hinge rod 207. The motor 201 is fixedly connected to the top outer wall of the housing 100. The rotating rod 202 is rotatably connected to the top inner wall of the housing 100. The movable end of the guide telescopic rod 206 is fixedly connected to the outer wall of the scraper 205. The protrusion 209 is engaged with the groove 210. One end of the connecting spring 208 is fixedly connected to the outer wall of the protrusion 209. The other end of the connecting spring 208 is fixedly connected to the inner wall of the moving rod 203. The protrusion 209 is slidably connected to the inner wall of the moving rod 203. The two ends of the connecting rod 204 are respectively hinged to the outer walls of the scraper 205 and the rotating rod 202. The two ends of the hinge rod 207 are respectively hinged to the outer walls of the scraper 205 and the moving rod 203.

[0023] The above solution allows for two states: scraper 205 can be retracted and extended. When retracted, scraper 205 does not contact the inner wall of housing 100, preventing wear caused by long-term friction between scraper 205 and the inner wall of housing 100 when the dust collector bag 400 rotates. After adsorption, scraper 205 can be extended to scrape the inner wall, allowing for cleaning only when needed, reducing wear and extending the service life of scraper 205. Moving rod 203 can move vertically within the inner wall of rotating rod 202. Because protrusion 209 engages with a set of grooves 210 under the elastic force of connecting spring 208, moving rod 203 cannot rotate independently but only rotates synchronously with rotating rod 202. A handle extends from the outer wall of moving rod 203 through the outer wall of rotating rod 202. Operators can grasp the handle and press protrusion 209 to disengage it from groove 210, thus moving rod 203 vertically. When the moving rod 203 moves upward, it will drive one end of the hinge rod 207 to move upward synchronously. The other end of the hinge rod 207 will push the connecting rod 204 to flip outward. When the connecting rod 204 flips, it will flip at the connection point with the rotating rod 202, which will push the scraper 205 outward. Since the scraper 205 is connected to the rotating rod 202 through the guide telescopic rod 206, the guide telescopic rod 206 plays a guiding role, so that the scraper 205 can only move laterally. This will drive the guide telescopic rod 206 to extend and move obliquely upward. When the moving rod 203 moves to the position where the protrusion 209 corresponds to the groove 210, the protrusion 209 will pop out under the elastic force of the connecting spring 208 and be stuck in the groove 210. At this time, the position of the moving rod 203 can be fixed, and the position of the unfolded scraper 205 can be fixed. The scraper 205 is attached to the inner wall of the housing 100, and the motor 201 can be started to perform scraping and cleaning operations through the scraper 205.

[0024] like Figures 5 to 7 As shown, the sealing mechanism 300 includes a connecting block A301. A sealing airbag 304 is fixedly connected to the inner wall of the connecting block A301. An air cylinder 307 is connected to the outer wall of the sealing airbag 304 through an air supply pipe 305. A valve 306 is provided on the inner wall of the air supply pipe 305. A pressure plate 309 is elastically connected to the inner wall of the air cylinder 307 through a return spring 308. A rotating wheel 311 is rotatably connected to the inner wall of the connecting block A301. A pull rope 310 is wound around the outer wall of the rotating wheel 311. A moving plate 312 is slidably connected to the inner wall of the connecting block A301. A connecting block B302 is provided on the outer wall of the air collection pipe 500 through a limiting component. A square groove 303 is opened on the inner wall of the connecting block B302.

[0025] Using the above scheme: Connecting block A301 is fixed to the outer wall of housing 100 by a vacuum pump. Connecting block B302 can be inserted into connecting block A301 and fixed by a limiting component, completing the connection between the gas collecting pipe 500 and housing 100. The vacuum pump can collect the dusty exhaust gas from wire production into housing 100. The sealing mechanism 300 can improve the sealing performance between connecting block A301 and connecting block B302 to prevent gas leakage during the vacuuming process, which could cause dust to drift into the working environment. The sealing mechanism 300 mainly seals the gap between connecting block A301 and connecting block B302 through the automatic expansion of the sealing airbag 304, thereby achieving a better sealing effect. When connecting block A301 and connecting block B302 are not connected, the return spring 308, due to its elasticity, keeps the pressure plate 309 in the inner right side of the air cylinder 307, and the moving plate 312 in the left side. Figure 6 As shown, in this state, the sealing airbag 304 is in a contracted state, and the gas is stored in the air cylinder 307. Since the gas is not under pressure at this time, the valve 306 seals the gas delivery pipe 305, and the connecting block A301 and the connecting block B302 are not connected.

[0026] like Figure 6 and Figure 7 As shown, connecting block A301 is fixedly connected to the outer wall of housing 100, one end of return spring 308 is fixedly connected to the outer wall of pressure plate 309, the other end of return spring 308 is fixedly connected to the inner wall of air cylinder 307, and pressure plate 309 is slidably connected to the inner wall of air cylinder 307; both ends of pull rope 310 are fixedly connected to the outer walls of moving plate 312 and pressure plate 309 respectively, connecting block B302 is in contact with the outer wall of connecting block A301, and connecting block B302 is in contact with the outer wall of moving plate 312.

[0027] Using the above scheme: When connecting block B302 is inserted into connecting block A301 and moves, its outer wall will push the moving plate 312 to the right. The moving plate 312 pulls one end of the pull rope 310 to move synchronously. When the pull rope 310 moves, it changes the direction of the pulling force through the rotating wheel 311. The other end pulls the pressure plate 309 to the left, and the return spring 308 is stretched. When the pressure plate 309 moves, it will squeeze the gas in the air cylinder 307 into the air delivery pipe 305. After the gas pushes open the valve 306, it will enter the sealing airbag 304, causing the sealing airbag 304 to inflate. When connecting block A301 is completely attached to the outer wall of connecting block B302, it is fixed by the limiting component. At this time, the sealing airbag 304... 04. Filling the joint between the inner wall of connecting block A301 and the outer wall of connecting block B302 can prevent dust from being scattered due to gas leakage during the evacuation process. After connecting block A301 and connecting block B302 are fixed, the gas in the sealing airbag 304 will not flow back into the air cylinder 307 due to the obstruction of the valve 306. When connecting block A301 and connecting block B302 are separated, the reset spring 308 will pull the pressure plate 309 to move in the opposite direction. The piston movement of the pressure plate 309 can push the gas in the sealing airbag 304 open the valve 306 and draw it back into the air cylinder 307. The sealing airbag 304 gradually contracts, thus avoiding the problem of material aging and cracking caused by the continuous expansion of the sealing airbag 304 when not in use.

[0028] like Figure 7 As shown, the limiting component includes a rotating ring 3001, the outer wall of the rotating ring 3001 is provided with an inclined groove 3002, the inner wall of the connecting block A301 is slidably connected with a slide rod 3003, and the inner wall of the connecting block A301 is elastically connected with a square block 3005 through a telescopic spring 3004.

[0029] The above solution allows for convenient and quick fixation of connecting block A301 and connecting block B302 via a limiting component, facilitating the disassembly and installation of the air collection pipe 500. Two sets of square blocks 3005, telescopic springs 3004, and sliding rods 3003 are symmetrically distributed on both sides of the inner wall of connecting block A301. Under normal conditions, the telescopic springs 3004 cause the square blocks 3005 to be in a pop-out state due to their elasticity, and they can engage with the square grooves 303 in the inner wall of connecting block B302, thus completing the connection and fixation between the two.

[0030] like Figure 7 As shown, the rotating ring 3001 is rotatably connected to the inner wall of the connecting block A301, the sliding rod 3003 is in contact with the inner wall of the inclined groove 3002, one end of the telescopic spring 3004 is fixedly connected to the outer wall of the square block 3005, the other end of the telescopic spring 3004 is fixedly connected to the inner wall of the connecting block A301, the square block 3005 is slidably connected to the inner wall of the connecting block A301, and the square block 3005 is engaged with the square groove 303.

[0031] Using the above solution: Under normal conditions, the elastic spring 3004 keeps the square block 3005 and the sliding rod 3003 in a certain position due to the elastic force. The operator can manually rotate the rotating ring 3001. When rotating, the inclined groove 3002 will squeeze the sliding rod 3003. Since the sliding rod 3003 is slidably connected to the inner wall of the connecting block A301, it can only move laterally, thus moving towards the middle and driving the square block 3005 to move synchronously, squeezing the telescopic spring 3004. At this time, the connecting block B302 can be inserted into the connecting block A301 and moved until the square block 3005 corresponds to the position of the square groove 303, and the two are locked together. When disassembling, the rotating ring 3001 is rotated to move the square block 3005 until it is no longer in contact with the square groove 303, thus releasing the limit and separating the connecting block B302 from the connecting block A301. This does not require operation by rotating the bolt, making it convenient and quick.

[0032] Working principle and usage process of this invention: The operator aligns the gas collecting pipe 500 with the connecting block A301 on the outer wall of the housing 100 via the connecting block B302, and slowly inserts it to make them fit together. At the same time, the rotating ring 3001 is manually rotated, and the square block 3005 moves into the inner wall of the connecting block A301. During the insertion process, the connecting block B302 pushes the moving plate 312 to the right, and the pull rope 310 pulls the pressure plate 309 to squeeze the gas in the air cylinder 307. The gas passes through the gas delivery pipe 305, pushes open the valve 306, and fills the sealing air bag 304, causing it to expand and fill the gap at the connection, thus achieving automatic sealing during the connection process. When the square groove 303 of the connecting block B302 corresponds to the position of the square block 3005 of the connecting block A301, the rotating ring 3001 is released, and the telescopic spring 3004 pushes the square block 3005 into the square groove 303, thus conveniently and quickly fixing the gas collecting pipe 500 to the housing 100.

[0033] Next, the suction pump connected to the gas collection pipe 500 is started to draw the dust-containing waste gas generated during the wire production process into the housing 100 through the gas collection pipe 500. After the waste gas enters, larger dust particles fall directly into the dust collection bag 600 at the bottom of the housing 100 under inertia, while smaller dust particles are adsorbed and filtered by multiple sets of dust collection bags 400. At the same time, the motor 201 can be started, which drives the rotating rod 202 to rotate at a constant speed. The rotating rod 202 synchronously drives the dust collection bags 400 to rotate, so that multiple sets of dust collection bags 400 are aligned with the air inlet of the gas collection pipe 500 in turn, avoiding dust overload of a single set of dust collection bags 400, ensuring stable adsorption efficiency, and the adsorbed and purified gas is discharged from the air outlet at the rear end of the housing 100.

[0034] After use, turn off the air pump and motor 201. First, hold the handle on the outer wall of the moving rod 203, press the protrusion 209 to disengage it from the groove 210, and pull the moving rod 203 upward. The moving rod 203 pushes the connecting rod 204 to flip through the hinge rod 207, causing the scraper 205 to unfold outward until the protrusion 209 re-engages with the upper groove 210 and the scraper 205 adheres to the inner wall of the housing 100. Then, start the motor 201 again. The rotating rod 202 drives the scraper 205 to rotate, scraping off the dust attached to the inner wall of the housing 100. The scraped dust falls into the dust collection bag 600.

[0035] After cleaning, turn off the motor 201, press the protrusion 209 to move the moving rod 203 down, and the scraper 205 will retract under the action of the connecting rod 204 and the guide telescopic rod 206. Loosen the detachable connection of the dust collection bag 600 at the bottom of the housing 100, take out the dust collection bag 600 and clean the dust inside. After cleaning, reinstall and fix it. If it is necessary to disassemble the air collection pipe 500, the rotating ring 3001 can be rotated to make the square block 3005 retract and disengage from the square groove 303, and the connecting block A301 and the connecting block B302 can be separated, so that the air collection pipe 500 can be easily and quickly removed.
