Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a bag dust collector for high-purity silicon nitride. Background Art

[0002] Bag filter is a kind of high-efficiency dry dust collector. It relies on filter bags made of fiber filter materials, and more importantly, it purifies the gas through the dust layer formed on the surface of the filter bag. For almost all dust in general industry, its dust removal efficiency can reach more than 99%.

[0003] For example, the Chinese patent: CN219722231U discloses the following technical solution: a bag dust collector for high-purity silicon nitride is disclosed, including a dust box, a gas outlet is connected to the top of one side wall of the dust box, a dust hopper is connected to the bottom of the dust box, and a dust inlet is connected to the bottom of the side wall of the dust box facing away from the gas outlet; a dust filter bag is fixedly installed in the middle of the dust box through a frame. The utility model is provided with a reciprocating motor and a top ball. During the use of the bag dust collector for high-purity silicon nitride, if the machine needs to be stopped to clean the filter bag, the reciprocating motor can be used to drive the transmission shaft to reciprocate up and down, and the motor drives the sleeve to move up and down. Since the top ball is limited by the tension spring, when the top ball moves past the bump, the tension spring shrinks adaptively, and then the tension spring gives the top ball a force to impact the non-bump area of ​​the dust box hopper, causing the hopper to vibrate intermittently. Compared with the existing method, the multi-point vibration and high-frequency vibration anti-blocking effect are more ideal.

[0004] However, in actual use, the dust removal method in the above patent requires vibrating the entire ash hopper to achieve the dust removal effect, and knocking the entire dust removal box may affect the use effect of the dust collector. Utility Model Content

[0026] The connecting plate 608 is fixedly connected to the inner wall of the dust removal box 3 , a threaded hole 609 is provided at the upper end of the connecting plate 608 , and the threaded rod 607 is threadedly connected to the threaded hole 609 .

[0027] In this embodiment, by setting up a cleaning mechanism, the threaded rod 607 can be driven to rotate while being lifted and lowered, thereby driving the mounting plate 701 to rotate during the lifting process, and then the dust bag 705 is vibrated and rotated up and down in cooperation with the tension spring 703 in the dust suction device, thereby achieving a dust removal effect on the dust bag 705.

[0028] Example 2

[0029] like Figure 2 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the dust suction device includes a mounting plate 701, the mounting plate 701 is fixedly connected to the bottom of the threaded rod 607, the outer wall of the mounting plate 701 is fixedly connected to the fixing ring 702, the interior of the fixing ring 702 is fixedly connected with a tension spring 703, the bottom of the tension spring 703 is fixedly connected with a mounting block 704, and the bottom of the mounting block 704 is fixedly connected with a dust bag 705.
