[0042] like Figures 1 to 11As shown, a dust removal device with a sintered plastic plate 5 that is easy to maintain includes: a housing, the inner side of which is provided with a working chamber, and a mounting plate 3 is provided in the working chamber.

[0045] A sealing gasket is provided between the lower mounting ring 204 and the mounting plate 3, which improves the sealing performance between the lower mounting ring 204 and the mounting plate 3.

[0046] A sealing gasket is provided between the upper mounting ring 103 and the mounting plate 3, which improves the sealing performance between the upper mounting ring 103 and the mounting plate 3.

[0047] The upper end of the upper shell 1 is fixed with a lifting lug 102, which facilitates the use of a crane to lift the upper shell 1 to replace and maintain the plastic sintered plate 5.

[0048] The lower end of the lower housing 2 is an inverted conical tube 201, which is connected to the filter chamber. The slag discharge pipe 202 is equipped with a star-shaped unloader, which can ensure the discharge of waste slag in a sealed manner. The air outlet pipe 101 is connected to the air inlet of the induced draft assembly. The induced draft assembly adopts, but is not limited to, existing induced draft fans.

[0049] A frame 301 is fixed on the lower end surface of the mounting plate 3. The frame 301 matches the inner side of the lower housing 2. The frame 301 is located inside the lower housing 2. The frame 301 not only strengthens the structural strength of the mounting plate 3, but also positions the mounting plate 3 during installation, aligning the second through hole with the first through hole and improving installation efficiency.

[0050] The width of the upper plate 503 is greater than the thickness of the sintered plate 5, and the length of the upper plate 503 is greater than the width of the sintered plate 5. A sealing gasket is provided between the upper plate 503 and the mounting plate 3. A vent hole 504 communicating with the inner side of the sintered plate 5 is opened on the upper plate 503.

[0051] The lower end of the plastic-coated plate 5 is fixedly provided with a lower plate 501, and the lower end of the lower plate 501 is fixedly provided with a positioning boss 502. The inner side of the lower housing 2 is fixedly provided with a support rod 9, and the support rod 9 has a positioning groove 901 corresponding to the positioning boss 502. The positioning boss 502 is installed inside the positioning groove 901. The support plate plays a positioning role for the lower end of the plastic-coated plate 5.

[0052] A compression spring 8 is provided between the head of the mounting bolt 7 and the pressure plate 6, and a washer 701 is provided between the compression spring 8 and the head of the mounting bolt 7. The outer diameter of the washer 701 is larger than the diameter of the spring.

[0053] The mounting plate 3 is fixed with an internally threaded tube 303 corresponding to the sliding hole. The mounting bolt 7 passes through the sliding hole and is threadedly connected to the internally threaded tube 303. The internally threaded tube 303 improves the connection strength of the mounting bolt 7.

[0054] The number of mounting holes 302 is multiple, and the multiple mounting holes 302 are evenly arranged along the length direction of the mounting plate 3. Each mounting hole 302 has a plastic sintered plate 5 on its inner side. Every two adjacent plastic sintered plates 5 correspond to a pressure plate 6. The lower end of the pressure plate 6 is fixed with two positioning posts 601. The two positioning posts 601 are respectively located in the positioning grooves of two adjacent plastic sintered plates 5. Moving one pressure plate 6 can release the pressing state of the two plastic sintered plates 5, which improves maintenance efficiency.

[0055] When replacing the plastic-coated plate 5, loosen the connecting bolts 4 and use a crane to lift the upper housing 1. At this time, the mounting bolts 7 and the positioning pin 601 can be loosened and disengaged from the mounting groove 505. Then, the pressure plate 6 can be rotated to release the restriction on the plastic-coated plate 5. Compared with the traditional method of completely disassembling the bolts, this method is more efficient and avoids the loss of bolts. Alternatively, the pressure plate 6 can be moved upward to compress the spring 8. After the positioning pin 601 is disengaged from the mounting groove 505, the pressure plate 6 can be rotated to release the restriction on the plastic-coated plate 5, thus improving maintenance efficiency.

[0056] In some embodiments, a pulse dust collector blowpipe is provided above the vent hole 504 of each sintered plate 5. The air outlet on the side wall of the pulse dust collector blowpipe corresponds to the vent hole 504 of the sintered plate 5. One end of the pulse dust collector blowpipe is closed and the other end is connected to the air outlet of the air compressor. Each pulse dust collector blowpipe is equipped with a solenoid valve. After a set time, the solenoid valve opens and the high-pressure gas in the pulse dust collector blowpipe enters the sintered plate 5, causing the dust on the surface of the sintered plate 5 to fall to the bottom of the filter chamber and be discharged through the slag discharge pipe 202.

[0057] Work process:

[0058] When the induced draft fan is started, both the filter chamber and the clean chamber are under negative pressure. The gas mixed with dust enters the filter chamber through the air inlet. The dust in the air accumulates on the surface of the sintered plate 5. Then the air passes through the sintered plate 5 and the air vent 504 into the clean chamber and is discharged from the air outlet, completing the dust removal operation.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
