Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a baghouse dust collector that is easy to maintain. Background Technology

[0002] A baghouse dust collector is a dry dust collection device that uses a tube sheet and filter bags below it to capture fine, dry, non-fibrous dust. The tube sheet has perforations, which are covered by the openings of the filter bags. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. Gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.

[0003] The aging of filter bags is mainly due to the following reasons: 1. Hardening and shrinkage due to abnormally high temperatures; 2. Reaction due to contact with the vapors of acids, alkalis, or organic solvents; 3. Reaction with moisture. In coal charging dust collection, the moisture and chemical properties of the coal entering the furnace cause the coal to be heated and evaporated, and the decomposition products of the coal enter the dust collection system along with the dust. This results in a large number of filter bags sticking to the internal support cages under the combined effects of moisture, high temperature, and acidic gases from the raw coal gas. During replacement, the cages and filter bags are difficult to separate.

[0004] (1) Currently, when replacing the filter bags, the top cover of the bag filter needs to be removed for replacement and maintenance. However, the following two problems have been found in actual use:

[0005] 1. There is a problem that some fabric bags are stuck to the cage frame and are difficult to separate;

[0006] 2. The outer side of the cloth bag is heavily dusty, and the replacement process is carried out in a harsh environment.

[0007] (2) To solve the above two problems, the following three methods are currently adopted:

[0008] 1. Repeatedly lifting and lowering the cage bones at the top to detach them is labor-intensive and ineffective.

[0009] 2. For most cases where this method is ineffective, the cage and the bag need to be lifted as a whole and the bag needs to be cut and peeled off with a sharp tool. This process involves the combined weight of the cage and the bag, which is labor-intensive. The dust accumulated on the outside of the bag cannot be cleaned at the tube sheet opening for the first time, making the operating environment even worse.

[0010] 3. After the cage frame is removed, the cloth bag is repeatedly rubbed against the opening of the tube sheet to reduce the amount of dust accumulated on the outside of the cloth bag during the removal process.

[0011] The above three problems severely restrict the speed of bag replacement, increase the labor intensity of operators, and deteriorate the operating environment. Existing remedial measures can only solve the problem by increasing the labor intensity of operators; they cannot reduce labor intensity or optimize the operating environment. Utility Model Content

[0012] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a bag filter dust collector that is easy to maintain. By setting up a vibrating separator with an electromagnet, it effectively treats dust accumulation and adhesion, eliminating the need to repeatedly lift and lower the cage. Furthermore, the walking mechanism used in conjunction with the vibrating separator further reduces the operator's workload, ensuring personnel safety while saving labor costs.

[0013] To achieve the above-mentioned technical effects, the present invention adopts the following technical solution:

[0014] A maintenance-friendly baghouse dust collector includes a baghouse dust collector body, which comprises a top cover, a tube sheet, and filter bags. The top cover is located on top of the baghouse dust collector body, and the tube sheet is located inside the baghouse dust collector body. The tube sheet has perforations, and the filter bags are detachably mounted below the tube sheet.

[0015] The bag filter dust collector is equipped with a traveling mechanism and a vibrating separator.

[0016] The traveling mechanism includes a horizontal bar and a vertical bar. The horizontal bar is disposed on the top surface of the bag filter, and the vertical bar is slidably disposed on the top surface of the horizontal bar. The vertical bar can move horizontally on the horizontal bar. A winch device is slidably disposed on the vertical bar, and a vibrating separator is connected to the bottom end of the winch device.

[0017] The vibrating separator includes an electromagnet and a vibrator. The top surface of the vibrator is connected to a hoisting device, and the bottom surface of the vibrator is connected to the electromagnet.

[0018] The vertical projection of the vibration separator is located within the vertical projection range of the perforated plate hole.

[0019] This utility model provides an easy-to-maintain baghouse dust collector. By incorporating a traveling mechanism and a vibrating separator, and limiting the size of the vibrating separator relative to the perforated tube sheet, the traveling mechanism moves the vibrating separator to the tube sheet or its perforation during bag replacement. A winch lowers the separator, and activating the electromagnet fixes it to the tube sheet or the cage inside the bag. The vibration effectively removes accumulated dust and dust adhesion. This eliminates the need for repeated bag lifting and lowering by operators, significantly reducing labor costs.

[0020] Preferably, there are two crossbars, both located outside the top cover of the bag filter. By placing the crossbars outside the top cover, it can be ensured that the traveling mechanism does not affect the disassembly and assembly of the top cover.

[0021] Preferably, the top surface of the crossbar is provided with a first slide rail, the bottom surface of the vertical bar is provided with a first slider, the first slide rail is provided with a first drive motor, and the first drive motor is used to drive the first slider to move within the first slide rail.

[0022] Preferably, the top surface of the vertical rod is provided with a second slide rail, the bottom surface of the winch device is provided with a second slider, and a second drive motor is provided on the second slide rail. The second drive motor is used to drive the second slider to move within the second slide rail.

[0023] Preferably, the vibrator is a compressed air vibrator, an electromagnetic vibrator, or other common commercially available vibrators.

[0024] Preferably, the bag filter body is also equipped with a PLC, which is electrically connected to the electromagnet, the vibrator, the first drive motor and the second drive motor respectively. The PLC is used to control the start, stop and operation of the electromagnet, the vibrator, the first drive motor and the second drive motor.

[0025] By adding a PLC, operators can directly control the PLC to address the issues of dust accumulation and adhesion on the bag filter body.

[0026] The beneficial effects of this utility model are as follows:

[0027] This utility model provides an easy-to-maintain baghouse dust collector. By incorporating a traveling mechanism and a vibrating separator, the vibrating separator, equipped with an electromagnet, allows for easy bag replacement and maintenance. The traveling mechanism moves the vibrating separator to the tube sheet or its opening, a winch lowers it, and activating the electromagnet secures the separator to the tube sheet or the cage inside the bag. The vibration effectively removes accumulated dust and prevents adhesion. This eliminates the need for repeated bag lifting and lowering by operators, significantly reducing labor costs.

[0038] The traveling mechanism includes a horizontal bar 6 and a vertical bar 7. The horizontal bar 6 is disposed on the top surface of the bag filter, and the vertical bar 7 is slidably disposed on the top surface of the horizontal bar 6. The vertical bar 7 can move horizontally on the horizontal bar 6.
