Description

Technical Field

[0001] This utility model belongs to the technical field of bag dust collectors, and specifically relates to a dust collection and cleaning device for bag dust collectors. Background Technology

[0002] A bag filter, also known as a fabric dust collector, is a dry dust filtration device that uses bag-shaped filter elements made of fibrous fabric to capture solid particles in dust-laden gas. Its working principle involves using porous bag-shaped filter elements to capture dust from the dust-laden gas. When the dust-laden gas enters the dust collector, larger dust particles settle down due to gravity and fall into the ash hopper, while finer dust particles are trapped as they pass through the filter media, thus purifying the gas. It is widely used in various scenarios such as flue gas dust removal in industrial furnaces and kilns, filtration and purification of dust-laden air in work areas, and filtration of exhaust gas from silos in pneumatic conveying systems.

[0003] Common baghouse dust collector cleaning devices have a relatively simple structure, making them inconvenient to clean. As dust accumulates on the filter media, the efficiency and resistance of the dust collector increase accordingly. Therefore, regular cleaning is required to maintain its efficient operation, which has certain adverse effects on users. To address this, we propose a baghouse dust collector cleaning device.

The two ends of the support rod are respectively positioned with the inner side of the support rod storage groove and the inner wall of the limiting sealing block. When the filter bag positioning frame extends and retracts inside the dust collection box, it can enhance stability. The outer sealing strip on the outer wall of the sealing plate can enhance the sealing performance, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dust collection and cleaning device for a bag filter includes a dust collection device support frame, a dust collection box fixedly connected to the inner wall of the dust collection device support frame, a cleaning adjustment mechanism positioned and installed on the inner side of the dust collection device support frame, a filter bag positioning frame fixedly connected to one side of the cleaning adjustment mechanism, a filter bag positioned and installed on the inner wall of the filter bag positioning frame, a dust inlet fixedly connected to the upper end of the dust collection box, and a dust outlet fixedly connected to the rear end of the dust collection box.

[0009] In a preferred embodiment, the cleaning and adjusting mechanism further includes a support rod, an adjusting moving block, a limiting moving block, and an internal through-threaded hole. The support rod is located inside the support rod storage groove. The adjusting moving blocks are located on both sides of one end of the filter bag positioning frame. The limiting moving blocks are located at the upper and lower ends of the adjusting moving block. The internal through-threaded hole is opened on the adjusting moving block (30).

[0010] In a preferred embodiment, the cleaning and adjusting mechanism further includes a sealing plate, a limiting sealing block, and an outer sealing strip. The sealing plate is located at one end of the filter bag positioning frame, the limiting sealing blocks are located on both sides of the sealing plate, and the outer sealing strip is located on the outer wall of the sealing plate.

[0011] In a preferred embodiment, one end of the control motor is fixed to both sides of the rear end of the dust collection box by bolts, and one end of the internal adjusting threaded rod passes through the inner side of the adjusting control groove and is connected to the control motor.

[0012] In a preferred embodiment, one end of the support rod is movably connected to the inner wall of the support rod storage groove, the other end of the support rod is engaged and positioned with the inner wall of the limiting sealing block, and one side of the adjusting moving block is fixedly connected to both sides of one end of the filter bag positioning frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention utilizes a cleaning and adjustment mechanism. An adjusting moving block, through an internal threaded hole, fits onto the outer wall of an internal adjusting threaded rod, positioning the filter bag positioning frame inside the dust collection box. A limiting moving block engages with the inner side of a limiting anti-detachment groove for restraint. When dust cleaning is required, a control motor drives the internal adjusting threaded rod to rotate within the adjusting control groove. This causes the adjusting moving block to extend and retract along the outer wall of the internal adjusting threaded rod, simultaneously extending and retracting the filter bag positioning frame inside the dust collection box until it extends outwards. This facilitates cleaning and replacement of the filter bags, more effectively removing dust and reducing wear and clogging caused by dust accumulation, thus extending the filter bag's lifespan. The two ends of the support rod are positioned with the inner side of the support rod storage groove and the inner wall of the limiting sealing block, respectively. The extension and retraction of the filter bag positioning frame within the dust collection box enhances stability, and the outer sealing strip on the outer wall of the sealing plate strengthens the sealing performance.
