Description

A Pulse Dust Collector Convenient for Cloth Bag Replacement

technical field

The utility model relates to the field of pulse dust collectors, in particular to a pulse dust collector which facilitates the replacement of cloth bags.

Background technique

The pulse bag filter is an improved new high-efficiency pulse bag filter based on the bag filter. The pulse filter is used to blow air to the bag and shake off the dust on the surface of the bag by setting a pulse mechanism above the bag. The cloth bag of the existing pulse dust collector is not easy to replace. In order to solve this problem, a related technology such as a pulse cloth bag dust collector with application number 202122985676.9 is easy to replace the cloth bag. By opening the side plate, sliding the horizontal plate horizontally, and removing the main body of the cloth bag , to replace and maintain the main body of the cloth bag. This method of disassembling the main body of the cloth bag has certain disadvantages. When taking out the horizontal plate, all the main bodies of the cloth bag need to be removed together. When one of the main bodies of the cloth bag is damaged, it is not convenient to disassemble a single main body of the cloth bag replace.

In view of this, we propose a pulse dust collector that is convenient to replace the bag to solve the above problems.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a pulse dust collector which is convenient to replace the bag, including the pulse dust collector body, the pulse dust collector includes a box body 1, the box body 1 is connected with an exhaust pipe 9, and the upper end of the box body 1 The upper cover plate 6 is detachably connected, the fixing mechanism between the upper cover plate 6 and the box body 1 is not shown, the outer wall of the box body 1 is fixed with a pulse valve 2, and the left end of the pulse valve 2 is externally connected to an air bag (not shown) One end of the pulse valve 2 is connected with an output pipe 3, which is the basic structure of the pulse dust collector. The working principle of the pulse dust collector will not be described in detail here, and the specific structure is not shown in the figure, which is the prior art;

What is different from the prior art is that a horizontal plate 10 is fixed inside the box body 1, and the horizontal plate 10 is provided with a perforation (not shown in the figure), and the keel 12 for supporting the cloth bag 11 is vertically inserted into the perforation and connected with the horizontal plate 10. The above-mentioned keel 12 and the horizontal plate 10 are fixed in the prior art, and will not be repeated here. One end of the output pipe 3 is fixed with a connecting pipe 4, and the connecting pipe 4 is rotationally connected with a blowing pipe 5, and the blowing pipe 5 The connecting end with the connecting pipe 4 is an L-shaped structure (as shown in Figure 2), and the part where the blowing pipe 5 is connected with the connecting pipe 4 is connected with a sealing gasket 14, and the sealing gasket 14 is fixed with the blowing pipe 5, and the sealing gasket 14 is connected with the connecting pipe 4. The inner surface of the bag 11 is in close contact to ensure the seal between the connecting pipe 4 and the blowing pipe 5, so that the pulse valve 2 can eject the airflow into the inside of the bag 11, and clean the bag 11. The initial state of the blowing pipe 5 is horizontally set in the bag 11 above, the lower end of the blowing pipe 5 is connected with the blowing head 7 corresponding to the position of the cloth bag 11, and the inner surface of the box body 1 is fixed with a blowing pipe support 13 of L-shaped structure, and the upper end of the vertical surface of the blowing pipe support 13 is connected with the spraying pipe.
