Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag replacement, and in particular to a dust collector filter bag replacement device. Background Technology

[0002] The simple harmonic dust collector is mainly used in the photovoltaic crystal pulling industry. It is installed between the crystal pulling furnace and the vacuum pump to prevent dust (mainly SiO) generated by the high-temperature interaction between the crucible and silicon solution in the single crystal furnace during the crystal pulling process from entering the vacuum pump with the argon gas flow.

[0003] The main function of a simple harmonic dust collector is to prevent dust from causing wear on pump body parts and greatly extend the service life of pump body parts. In other words, it will affect the service life of the filter bags. Therefore, the filter bags should be regularly maintained, cleaned or replaced during use. When the filter bag resistance increases and greatly affects the dust removal effect, the filter bags should be replaced in time to ensure the service life of the simple harmonic dust collector.

[0004] In the photovoltaic industry, current technology only supports manual replacement of filter bags, and the replacement process is cumbersome and time-consuming, which increases machine downtime. To meet production needs, a higher number of skilled personnel is required, which is impossible given the current market conditions and staffing levels. Overall, production output cannot be achieved, significantly impacting production efficiency. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a filter bag replacement device for a dust collector.

[0006] To solve the above technical problems, this utility model provides a filter bag replacement device for a dust collector, comprising: a base plate, a positioning rod fixedly connected to the upper surface of the base plate, an auxiliary structure provided on the lower surface of the base plate, the auxiliary structure including four limiting blocks, the four limiting blocks being installed on the base plate, wheels rotatably connected to the inner walls of the limiting blocks, a hydraulic rod installed on the upper surface of the base plate, a connecting plate fixedly connected to the output end of the hydraulic rod, a fixing rod fixedly connected to the upper surface of the connecting plate, a servo motor fixedly connected to the upper end of the fixing rod, a sliding plate slidably connected to the arc surface of the positioning rod, a bracket rotatably connected to the upper surface of the sliding plate, a turntable fixedly connected to the inner wall of the bracket, the turntable being movably connected to the positioning rod, and a connecting plate fixedly connected to the output end of the servo motor. The positioning rod is rotatably connected. Two connecting blocks are fixedly connected to the arc surface of the connecting plate. A telescopic rod is fixedly connected to the lower surface of the connecting block. The telescopic rod is fixedly connected to the turntable. Two electric actuators are installed at the end of the bracket away from the positioning rod. An auxiliary plate is fixedly connected to the output end of the electric actuator.

[0007] The aforementioned components achieve the following effect: When the filter cover needs to be removed to replace the filter bag, the base plate is moved first. The base plate moves the positioning rod, which in turn moves the limiting block and wheels. The wheels rotate on the inner wall of the limiting block, thus moving the base plate. After moving to the appropriate position, the hydraulic rod is activated, moving the connecting plate. The connecting plate moves the sliding plate, which moves the sliding plate on the arc surface of the positioning rod. The sliding plate moves the bracket and turntable. After moving to the appropriate position, the clamping plate is aligned with the cover, and then the electric actuator is activated, moving the slip ring. The filter bag slides on the arc surface of the round rod, the slip ring drives the auxiliary block to move, the auxiliary block drives the connecting rod to move, the connecting rod drives the connecting groove and the sliding rod to move, the sliding rod drives the clamping plate to hold the cover, and then the hydraulic rod is started to continue to rise. After rising to the appropriate position, the servo motor is started to rotate, the servo motor drives the connecting plate to move, the connecting plate drives the telescopic rod to move, the telescopic rod drives the turntable to rotate, the turntable drives the bracket to rotate on the sliding plate, the bracket drives the round rod and the connecting rail to move, the connecting rail drives the sliding rod and the clamping plate to move, and then the clamping plate drives the cover to move, which makes it easy to replace the filter bag.

[0008] Preferably, anti-slip pads are fixedly connected to the sides of the four clamping plates that are close to each other, and the cross-section of the anti-slip pads is arc-shaped.

[0009] The effect achieved by the above components is that the anti-slip pad can increase the friction between the clamp and the cover, preventing the clamp from sliding when holding the cover.

[0010] Preferably, the arc surface of the slide bar is fixedly connected to two washers, and the washers have a circular cross-section.

[0013] The effect achieved by the above components is that the limiting rod can limit the sliding rod, preventing it from deviating during use and improving the stability of the sliding rod.

[0014] Preferably, the cross-section of the fixing rod is "L" shaped, and the fixing rod is a stainless steel rod.

[0015] The effect achieved by the above components is that the stainless steel material can increase the service life of the fixing rod and prevent the fixing rod from rusting during use.

[0016] Preferably, the arc surface of the wheel has a plurality of slots, and the plurality of slots are evenly distributed on the wheel.

[0019] Compared with related technologies, the filter bag replacement device for a dust collector provided by this utility model has the following beneficial effects:

[0020] Existing technologies, through the inclusion of auxiliary structures, only support manual filter bag replacement. This process is cumbersome and time-consuming, leading to increased equipment downtime and impacting production continuity and efficiency. To ensure production demands are met, it is often necessary to increase the number of personnel and improve operator skill levels. However, considering current staffing levels and industry standards, this approach struggles to achieve the expected production efficiency. To address this issue, this device optimizes its mechanical structure design to shorten the operation time during filter bag replacement. By simplifying preparation and disassembly of the harmonic dust collector, operation becomes more convenient, effectively reducing overall replacement time and improving production efficiency. This design requires fewer operators; at least one person can complete the filter bag replacement. With two people working together, replacement time can be further shortened, significantly improving production efficiency. Attached Figure Description

A servo motor 308 is fixedly connected to the upper end of the fixing rod 307. A sliding plate 303 is slidably connected to the arc surface of the positioning rod 2. A bracket 309 is rotatably connected to the upper surface of the sliding plate 303. A turntable 313 is fixedly connected to the inner wall of the bracket 309. The turntable 313 is movably connected to the positioning rod 2. A connecting plate 316 is fixedly connected to the output end of the servo motor 308. The connecting plate 316 is rotatably connected to the positioning rod 2. Two connecting blocks 315 are fixedly connected to the arc surface of the connecting plate 316. The lower surface of the connecting blocks 315 is fixedly... A telescopic rod 314 is connected to a turntable 313. Two electric actuators 310 are installed at the end of the bracket 309 away from the positioning rod 2. An auxiliary plate 317 is fixedly connected to the output end of the electric actuator 310. A slip ring 326 is fixedly connected to the end of the auxiliary plate 317 that is close to each other. Four auxiliary blocks 323 are fixedly connected to the arc surface of the slip ring 326. A round rod 312 is fixedly connected to the lower end of the bracket 309 away from the positioning rod 2. The round rod 312 is slidably connected to the slip ring 326. A connecting rail 311 is fixedly connected to the arc surface of the lower end of the round rod 312. A sliding rod 319 is slidably connected to the inner wall of the connecting rail 311. A connecting groove 322 is opened at the upper end of the sliding rod 319. A connecting rod 318 is rotatably connected to the inner wall of the connecting groove 322. The connecting rod 318 is rotatably connected to the auxiliary blocks 323. A clamping plate 324 is fixedly connected to the lower end of the sliding rod 319.When the filter cover needs to be removed to replace the filter bag, first move the base plate 1. The base plate 1 moves the positioning rod 2, which in turn moves the limiting block 304 and the wheel 305. The wheel 305 rotates on the inner wall of the limiting block 304, thus moving the base plate 1. After moving to the appropriate position, start the hydraulic rod 301. The hydraulic rod 301 moves the connecting plate 302, which in turn moves the sliding plate 303. The sliding plate 303 moves on the arc surface of the positioning rod 2, and the sliding plate 303 moves the bracket 309 and the turntable 313. After moving to the appropriate position, align the clamping plate 324 with the cover, and then start the electric push rod 310.

The connecting rod 318 moves, which in turn moves the connecting groove 322 and the slide rod 319. The slide rod 319 clamps the cover with the clamping plate 324. Then, the hydraulic rod 301 is started to continue rising. After rising to the appropriate position, the servo motor 308 is started to rotate. The servo motor 308 moves the connecting plate 316, which in turn moves the telescopic rod 314. The telescopic rod 314 rotates the turntable 313, which in turn moves the bracket 309 on the slide plate 303. The bracket 309 moves the round rod 312 and the connecting rail 311, which in turn moves the slide rod 319 and the clamping plate 324. Then, the clamping plate 324 moves the cover, which facilitates the replacement of the filter bag. Anti-slip pads 325 are fixedly connected to the sides of the four clamping plates 324 that are close to each other. The cross-section of the anti-slip pads 325 is arc-shaped. The anti-slip pad 325 increases the friction between the clamping plate 324 and the cover, preventing the clamping plate 324 from sliding when holding the cover. Two washers 320 are fixedly connected to the arc surface of the slide rod 319; the washers 320 have a circular cross-section. The washers 320 limit the slide rod 319, preventing it from tilting when sliding on the inner wall of the connecting rail 311. A limiting rod 321 is fixedly connected inside the connecting rail 311, and the limiting rod 321 is slidably connected to the slide rod 319. The limiting rod 321 limits the slide rod 319, preventing it from shifting during use and improving the stability of the slide rod 319. The fixing rod 307 has an "L"-shaped cross-section and is made of stainless steel. The stainless steel material can increase the service life of the fixing rod 307 and prevent the fixing rod 307 from rusting during use. The arc surface of the wheel 305 has several slots 306, which are evenly distributed on the wheel 305.The groove 306 can increase the friction between the wheel 305 and the contact surface, and prevent the wheel 305 from sliding with the contact surface during use. The fixing rod 307 is fixedly connected to the connecting plate 302 by welding. The connecting plate 302 is a stainless steel plate.

[0031] The working principle of the filter bag replacement device for a dust collector provided by this utility model is as follows: When it is necessary to remove the filter cover to replace the filter bag, the base plate 1 is moved first. The base plate 1 drives the positioning rod 2 to move, and the base plate 1 drives the limiting block 304 and the wheel 305 to move. The wheel 305 rotates on the inner wall of the limiting block 304, thereby moving the base plate 1. After moving to the appropriate position, the hydraulic rod 301 is activated. The hydraulic rod 301 drives the connecting plate 302 to move, and the connecting plate 302 drives the sliding plate 303 to move. The sliding plate 303 moves on the arc surface of the positioning rod 2. The sliding plate 303 moves the support 309 and turntable 313 to the appropriate position, aligning the clamping plate 324 with the cover. Then, the electric actuator 310 is activated, moving the slip ring 326, which slides on the arc surface of the round rod 312. The slip ring 326 moves the auxiliary block 323, which in turn moves the connecting rod 318. The connecting rod 318 moves the connecting groove 322 and the sliding rod 319, which in turn clamps the cover with the clamping plate 324. Then, the hydraulic rod 301 is activated to continue the upward movement, reaching the appropriate position. Once the desired position is reached, the servo motor 308 is activated to rotate. The servo motor 308 drives the connecting plate 316 to move, which in turn drives the telescopic rod 314 to move. The telescopic rod 314 then drives the turntable 313 to rotate, which in turn drives the bracket 309 to rotate on the slide plate 303. The bracket 309 then drives the round rod 312 and the connecting rail 311 to move. The connecting rail 311 then drives the slide rod 319 and the clamping plate 324 to move. Finally, the clamping plate 324 moves the cover, facilitating filter bag replacement. The anti-slip pad 325 increases the friction between the clamping plate 324 and the cover, preventing... When the clamp-free plate 324 is clamped, it may slip. The gasket 320 can limit the sliding rod 319 to prevent it from tilting when sliding on the inner wall of the connecting rail 311. The limiting rod 321 can limit the sliding rod 319 to prevent it from deviating during use, thus improving the stability of the sliding rod 319. The stainless steel material can increase the service life of the fixing rod 307 and prevent it from rusting during use. The groove 306 can increase the friction between the wheel 305 and the contact surface, preventing the wheel 305 from slipping on the contact surface during use.
