Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a high-efficiency pulse composite bag dust collector. Background Art

[0002] A bag dust collector, also known as a bag-type dust collector, is a dry dust filtering device, mainly used to capture fine, dry, non-fibrous dust. Its working principle is to use the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper; while the gas containing finer dust is retained when passing through the filter material, thereby purifying the gas. The pulse device is to clean the dust accumulated on the bag, thereby increasing the service life of the bag.

[0003] When the pulse device of the existing pulse bag dust collector cleans the bags, the dust on the bags will be dispersed due to the impact force, which will cause some dust to be adsorbed to the surface of the bags for a second time and discharged from the exhaust pipe along with the gas, causing the dust removal efficiency of the dust collector to decrease and affecting the user experience. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing technology has the disadvantage that dust is easily adsorbed twice when the bag is used for dust cleaning. For this reason, we propose a high-efficiency pulse composite bag dust collector.

[0009] Preferably, the interior of the limiting cover is sprayed with a smooth coating.

[0010] Preferably, an ash suction device is installed at the bottom end of the ash hopper.

[0011] Preferably, a second groove is provided at one end and the other end of the dust collector shell, a traction rod is installed inside the second groove, an end of the traction rod close to the fixed plate is fixedly connected to a connecting block, a circular groove is provided at the top of the second groove, a connecting plate is installed at the top of the dust collector shell, a threaded rod is connected to the internal thread of the connecting plate, a rotating plate is installed at the end of the threaded rod away from the traction rod, and a first limiting hole and a second limiting hole used in conjunction with the threaded rod are provided on the surface of the traction rod.

[0012] Preferably, third sliding grooves are provided on both sides of the second slot, third sliding blocks are fixed on both sides of the traction rod, and the interior of the third sliding groove is slidably connected to the third sliding block.

[0013] Technical effects and advantages of the utility model:

[0014] In the utility model, when the staff needs to install the limit cover on the surface of the bag body, the buckle is aligned with the slot and buckled into the bag. After the buckling is completed, the elastic force of the elastic spring makes the buckle firmly fixed in the slot, so that the limit cover is installed. When the staff needs to remove the limit cover, the push-pull plate is pressed inward to make the sliding rod press against the buckle, so that the buckle and the slot are released from the limit, and the limit cover is released from the limit. Through the setting of the limit cover, the pulse device can effectively prevent dust from splashing on the bag when performing pulse cleaning on the bag, thereby improving the cleanliness of the gas discharged by the device, and the rapid installation and disassembly can significantly improve the work efficiency of the staff and enhance the user experience.

[0015] When the bag is to be replaced, the staff can simply disassemble the pulse device, rotate the rotating plate outward to drive the threaded rod to rotate out of the first limiting hole, so that the traction rod is released from the limit, and then the traction rod drives the fixed plate to be pulled out, and align the rotating plate with the second limiting hole to drive the threaded rod to rotate in, so that the traction rod and the fixed plate are limited, so that the fixed plate can be conveniently pulled out as a whole when the bag needs to be replaced, thereby avoiding the staff from entering the dust collector shell to replace the bag, thereby improving the safety during work.

Through the setting of the first slide groove 18 and the first slide block 19, the buckle 11 can be more stable when it is inserted into the slot 13, thereby improving the installation of the limit cover 7. The second slide groove 20 and the second slider 21 can form a stable limit when the sliding rod 16 moves inside the limit sleeve 15, preventing the sliding rod 16 from falling off due to excessive pulling force, affecting normal use. Through the setting of the return spring 22, when the limit cover 7 is disassembled, the elastic force stored in the return spring 22 is released, driving the sliding rod 16 to rebound quickly, thereby realizing the rapid reset of the sliding rod 16 after use, which is convenient for the next use.
