Description

Technical Field

[0001] This utility model relates to the field of dust collector bag technology, specifically a spring-loaded dust collector bag. Background Technology

[0002] Spring dust collector bags are a common industrial dust collection device, mainly used in dust filtration systems for the efficient collection of fine particulate matter. Their working principle is to achieve dust separation when the airflow passes through the filter material through the interception effect of the bag fiber layer and the synergistic effect of the spring support structure. At the same time, the elastic deformation characteristics of the spring system assist in dust cleaning and regeneration.

[0003] The utility model patent CN221207200U discloses a bag filter dust collector for a smelting workshop, including a dust collector body, a bag vibration assembly, and a bag scraping assembly. The bag vibration assembly and the bag scraping assembly are fixed on one inner wall of the dust collector body. The bag vibration assembly includes a motor, a first gear, a first annular groove, an end face toothed ring, a first slip ring, an extrusion arc plate, a support plate, a filter bag, a connecting plate, a telescopic rod, and a spring. The support plate is welded to one inner wall of the dust collector body.

[0004] The above technical solution employs a bag vibration component to perform dust removal on the bags, making it easy to remove dust from the bags without the need for repeated bag replacements, thus improving the dust removal effect. It also uses a bag scraping component to scrape material from the bags, thereby assisting in dust removal and ensuring the dust removal effect is improved. However, when dust removal is required for vertical or horizontal bags, the installation and removal of the bags require manual adjustment and fixation, which is time-consuming and labor-intensive. Furthermore, the concentrated airflow impacts the top of the bag, causing rapid wear at the top while other parts remain new, rendering the entire bag unusable prematurely. Utility Model Content

[0005] The purpose of this utility model is to provide a spring-loaded dust collector bag to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A spring-loaded dust collector bag includes a bag and a fixing device installed on the top of the bag. A connecting block is provided on the top of the fixing device.

At the same time as the disc rotates, the track rotates synchronously. The movable block can move inward and outward on the track through the bottom groove. When it is necessary to install and fix the cloth bag, the rotating rod is rotated clockwise, and the movable block moves inward, driving the push rod to limit and fix the cloth bag. Then, through the threaded nail provided on the top of the connecting block, the threaded nail passes through the connecting block, the outer shell and the disc, all the way to the bottom of the disc shell. Tightening the threaded nail limits the position of the disc surface by the friction force of the threaded nail, preventing the disc, gear and movable block from loosening during dust removal.

[0011] Preferably, the push plate is T-shaped and has an arc-shaped front end, which is compatible with the cloth bag.

[0012] In this invention, the front side of the push plate is designed to fit against the outer wall of the barrel-shaped cloth bag, thus limiting the position of the cloth bag.

[0016] In this invention, the spiral guide plate is inserted from top to bottom through the opening at the top of the connecting block until the base is in contact with the bottom of the bag. The spiral guide plate guides the airflow to rotate, and the airflow is evenly distributed inside the bag, reducing the problem of local wear caused by the airflow impacting the bag. The base is adapted to the bottom of the bag to prevent the bottom of the bag from sinking.

[0017] Preferably, the spring has a dense pitch at both ends and a sparse pitch in the middle.

[0018] This invention improves the deformation resistance of the spring ends, allows for flexible deformation of the middle part of the spring, absorbs the main load energy, reduces the problem of failure caused by end fatigue deformation, and extends the service life of the spring.

[0019] Preferably, the top end of the spring is fastened to the top of the side wall of the bag with a snap fastener, the bottom end of the spring is fastened to the bottom of the side wall of the bag with a snap fastener, and the top of the bag has an opening, which is sewn together with needle and thread.

[0020] In this invention, the spring is fixed to the side wall, top and bottom of the bag by snap fasteners. After dust removal, the worker can separate the spring from the bag by unfastening the snap fasteners and sew the opening closed with needle and thread. This method minimizes damage to the bag and reduces the contamination of the bag by the needle and thread. When disassembly is required, the spring can be removed simply by cutting the thread.

[0039] In this embodiment, the cross-shaped fixing rod 202 is fixed to the fixing post 201. The cross-shaped fixing rod 202 is fixed by inserting it into the groove 101. Then, the four threaded pins at the top of the cross-shaped fixing rod 202 are screwed to fix it to the groove 101, thereby limiting the position of the spiral guide plate 2 and the fixing post 201 so that they will not loosen.

[0040] Specifically, a spiral guide vane 2 is provided in the middle of the connecting block 1, a fixing post 201 is provided in the middle of the spiral guide vane 2, a cross fixing rod 202 is provided at the top of the fixing post 201 corresponding to the groove 101, the inner ring of the spiral guide vane 2 is tightly fitted to the outer wall of the fixing post 201 and welded and fixed, and a base 203 is provided at the bottom of the fixing post 201, the top of the base 203 is welded and fixed to the bottom of the fixing post 201, and the outer diameter of the base 203 is adapted to the outer diameter of the spiral guide vane 2.

[0041] In this utility model, the spiral guide plate 2 is inserted from top to bottom through the opening 501 at the top of the connecting block 1 until the base 203 is in contact with the bottom of the cloth bag 5. The spiral guide plate 2 guides the airflow to rotate, and the airflow is evenly distributed inside the cloth bag 5, reducing the problem of local wear caused by the airflow impacting the cloth bag 5. The base 203 is adapted to the bottom of the cloth bag 5 to prevent the bottom of the cloth bag 5 from sinking.

[0042] Specifically, a spring 4 is provided between the inner wall and the outer wall of the bag 5. The two ends of the spring 4 are designed with a dense pitch and the middle is designed with a sparse pitch. The top of the spring 4 is fastened to the top of the side wall of the bag 5 with a buckle, and the bottom of the spring 4 is fastened to the bottom of the side wall of the bag 5 with a buckle. The top of the bag 5 has an opening 501, and the opening 501 is sewn together with needle and thread.

[0043] In this invention, the deformation resistance of the ends of the spring 4 is improved, allowing the middle part of the spring 4 to deform flexibly, absorbing the main load energy, reducing the problem of failure caused by end fatigue deformation, and extending the service life of the spring 4.

[0045] In this invention, the teeth on the surface of gear 308 and the tooth grooves 307 on the bottom surface of disk 306 are both inclined. Gear 308 and disk 306 are meshed and fixed. A layer of anti-slip pad is sleeved on the surface of rotating rod 309 to prevent slippage. When rotating rod 309 is rotated, it drives gear 308 to rotate, and the rotation of gear 308 drives disk 306 to rotate. At the same time as disk 306 rotates, track 305 rotates synchronously. Thus, movable block 304 can move inward and outward on track 305 through bottom groove 310. When it is necessary to install and fix cloth bag 5, rotating rod 309 clockwise causes movable block 304 to move inward, bringing... The push rod limits and fixes the filter bag 5. Then, through the threaded nail on the top of the connecting block 1, the threaded nail passes through the connecting block 1, the outer shell 30 and the disc 306, all the way to the bottom of the disc 306. Tightening the threaded nail limits the position of the disc 306 by the friction force on the surface of the disc 306, preventing the disc 306, gear 308 and movable block 304 from loosening during dust removal. The front shape of the push plate 303 is designed to fit against the outer wall of the barrel-shaped filter bag 5, limiting the position of the filter bag 5.

[0046] In this embodiment, when using the spring dust collector bag, firstly, the connecting block 1 is fixedly connected to the outer shell 30, the gear 308 with the rotating rod 309 is rotatably connected to the circular groove 302, the disc 306 with the track 305 and the toothed groove 307 is meshed with the gear 308, then the movable block 304 with the sliding groove 310 is slidably connected to the track 305, the push plate 303 is slidably connected to the movable block 304 in the T-shaped groove 301, then the cross fixing rod 202 with the fixing column 201 and the spiral guide plate 2 is inserted and installed into the groove 101, the base 203 is welded and fixed to the fixing column 201, the spring 4 and the bag 5 are snapped and fixed, and then the opening 501 is sewn together with needle and thread, and then the bag 5 is attached to the push plate 303.

[0047] When dust removal is required, first insert the spring 4 into the bag 5 through the opening 501, and then fasten the spring 4 to the inner wall of the bag 5 with the clips. Next, sew the opening 501 closed. Insert the spiral guide vane 2 from top to bottom into the connecting block 1. Insert and fix the cross-shaped fixing rod 202 into the groove 101, thus limiting the position of the spiral guide vane 2, the fixing post 201, and the base 203. Then, tighten the four threaded nails to fix them to the groove 101, further limiting the position of the cross-shaped fixing rod 202. Finally, insert the bag 5 from the connecting block 1... Pull down to install and fix the top of the bag 5 to the top of the outer shell 30. Rotate the rotating rod 309 clockwise. The rotation of the rotating rod 309 drives the gear 308 to rotate. The gear 308 meshes with the tooth groove 307 at the bottom of the disc 306, thereby driving the disc 306 and the track 305 to rotate. The rotation of the track 305 drives the movable block 304 with the sliding groove 310 to rotate. In turn, the movable block 304 drives the push plate 303 to move inward and limit the position of the bag 5. Then, tighten the threaded nail to limit the position of the disc 306.
