Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically a dust removal mechanism for paper-faced gypsum board production. Background Technology

[0002] Cutting is an essential step in the production and processing of paper-faced gypsum board. However, the cutting process generates a large amount of dust, which not only permeates the production workshop, causing serious pollution to the working environment and affecting the health of workers, but also may lead to occupational diseases if exposed to high dust levels for a long time.

[0003] To address the dust problem generated during the cutting process, dust collection mechanisms are widely used in gypsum board production equipment. Among these, the dust hood, a key component of the dust collection mechanism, is typically installed above the cutting equipment to collect the dust generated during cutting and transport it to subsequent dust collection equipment (such as a bag filter) for processing. However, existing dust hoods present several inconveniences in practical use. After prolonged use, a large amount of dust and impurities accumulate inside the dust hood, requiring regular maintenance and cleaning. However, due to the structural design limitations of the dust hood, when cleaning the inside, workers often need to insert tools inside. The relatively small space inside the dust hood restricts tool operation, making cleaning difficult and resulting in incomplete cleaning of every corner. Therefore, we propose a dust collection mechanism for gypsum board production. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal mechanism for paper-faced gypsum board production, which solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal mechanism for paper-faced gypsum board production, comprising a bag filter and a dust collection hood.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] As attached Figure 1-4As shown, this utility model provides a technical solution: a dust removal mechanism for paper-faced gypsum board production, including a bag dust collector 1 and a dust collection hood 3. The input end of the bag dust collector 1 is connected to a four-way pipe 2. The front and back of the dust collection hood 3 are respectively provided with a cover plate 4 and a cover plate 8. The top ends of the cover plate 4 and the cover plate 8 are hinged to the dust collection hood 3. The inner sides of the cover plate 4 and the cover plate 8 and the top of the inner wall of the dust collection hood 3 are all fixedly installed with a suction head 5. The top of the suction head 5 is connected to a conduit 6. The other ends of the three sets of conduits 6 are respectively connected to the remaining three ports of the four-way pipe 2 through flexible hoses 7. The inner sides of the cover plate 4 and the cover plate 8 are fixedly installed with a hinge seat 2 11. The top of the inner wall of the dust collection hood 3 is fixedly installed with a hinge seat 9. A gas spring 10 is hinged between the hinge seat 9 and the hinge seat 2 11.

[0023] A shrinkage groove 13 is provided on one side of the inner wall of the dust hood 3. An L-shaped locking block 12 is inserted into the shrinkage groove 13. A locking groove 14 is provided at the bottom of both the first cover plate 4 and the second cover plate 8. A lever 16 is fixedly installed on one side of the L-shaped locking block 12. A sliding groove 15 is provided between one side of the dust hood 3 and the inner wall of the shrinkage groove 13. The lever 16 moves through the sliding groove 15. A limiting rod 17 is fixedly installed on the inner wall of the sliding groove 15. The limiting rod 17 moves through the lever 16. A spring 18 is surrounded on the outer wall of the limiting rod 17. The spring 18 is fixedly installed between the bottom of the lever 16 and the inner wall of the sliding groove 15.

[0024] Specifically, in the above technical solution, when using the dust removal mechanism for paper-faced gypsum board production, the dust suction hood 3 can be fixed above the paper-faced gypsum board cutting equipment via the mounting plate 19. Then, the bag filter 1 is started, and the dust generated during the cutting of the paper-faced gypsum board can be guided from the dust suction hood 3 into the bag filter 1 for dust removal through the four-way pipe 2, flexible hose 7, conduit 6, and dust suction head 5. After the dust suction hood 3 has been used for a long time, the lever 16 can be moved downwards to compress the spring 18, causing the lever 16 to move the L-shaped locking block 12 downwards, thus disengaging the L-shaped locking block 12 from the slot 1. 4. At this point, the operator gently pushes the first cover 4 and the second cover 8 upwards. The first cover 4 and the second cover 8 will then automatically rotate upwards under the action of the gas spring 10, causing the first cover 4 and the second cover 8 to unfold. This makes it easier for the operator to maintain and clean the inside of the vacuum hood 3, greatly reducing the difficulty of maintenance and cleaning, and improving the efficiency of maintenance. This solves the problem that when the existing vacuum hood 3 needs to be cleaned, the operator has to insert tools into the vacuum hood 3, resulting in a small operating space, high cleaning difficulty, and a significant impact on the operator's work efficiency.

[0025] Furthermore, a sealing gasket is installed between cover plate 4, cover plate 8 and dust hood 3, and the sealing gasket is fixedly installed on the inner wall of dust hood 3;

[0026] By setting a sealing gasket, the sealing between cover plate 4 and cover plate 8 and the dust hood 3 can be increased.

[0027] Furthermore, mounting plates 19 are fixedly installed on both sides of the dust cover 3, and positioning holes are provided on the mounting plates 19;

[0028] The installation plate 19 facilitates the installation of the dust hood 3 by personnel.

[0029] Furthermore, there are two shrinkage grooves 13, and the L-shaped locking blocks 12 in the two shrinkage grooves 13 are respectively locked into the locking grooves 14 opened at the bottom of the cover plate 1 4 and the cover plate 2 8.

[0030] By setting an L-shaped locking block 12, the L-shaped locking block 12 can be inserted into the locking slot 14, thereby limiting and fixing the cover plate 1 4 and cover plate 2 8 when folded and covered, improving the stability of cover plate 1 4 and cover plate 2 8 on the dust collection cover 3.

[0031] Furthermore, the L-shaped card block 12 is adapted to the card slot 14.

[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
