Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-6, the present utility model provides a self-plugging ceramic filter tube protection device in a first aspect, which is used for being installed at an opening of a filter tube 100 to cover the opening, the self-plugging ceramic filter tube protection device comprises a fixing plate 200, a filter cover 300 and a sealing plate 400 installed on a second side of the filter cover 300, the filter cover 300 is in a hollow truncated cone-shaped structure with openings on two sides, a plurality of limiting bodies 301 are uniformly arranged on the inner side wall of the filter cover 300, the first side of the filter cover 300 is reversely buckled at the opening of the filter tube 100 through the fixing plate 200 and is connected with the opening, the sealing plate 400 is used for shielding the opening on the second side of the filter cover 300, the self-plugging ceramic filter tube protection device further comprises a nozzle tube 500, a connecting hole 401 is arranged on the sealing plate 400, the nozzle tube 500 extends into the filter cover 300 from the connecting hole 401, and the connecting hole 401 is sealed with the tube wall of the nozzle tube 500.

Specifically, as shown in fig. 1, when the filter tube 100 is inserted into the filter cavity (not shown in the drawings, specifically, the peripheral portion of the filter tube 100), and in fact, when the air is filtered in the filter cavity, the flow direction of the air passes through the filter tube 100 from the filter cavity, so that some dust 600 is accumulated on the side of the filter tube 100 facing the filter cavity, but the use of the filter tube 100 for a long time or the occurrence of some accidents may cause damage to the filter tube 100 and the occurrence of a breakage 700, as shown in fig. 6, if the self-plugging ceramic filter tube protection device is not installed at the opening of the filter tube 100, the dust 600 enters along the filter tube 100 for storing the filtered air, thereby affecting surrounding filter tube units. In the utility model, by additionally arranging the self-plugging ceramic filter tube protection device at the opening of the filter tube 100, the subsequent air flows out from two sides of the filter cover 300, dust particles in the air are captured by the limiting body 301 on the inner side wall of the filter cover 300, so as to achieve a safety effect, after the filter tube 100 is damaged, the self-plugging ceramic filter tube protection device can prevent dust-containing flue gas from overflowing for the first time, realize self plugging, reduce the probability of dust-containing flue gas overflowing, improve the protection of surrounding filter tube units, and the outside of the nozzle tube 500 is connected with dust removing equipment, as shown in fig. 5, the dust removing equipment conveys gas into the filter tube 100 from the nozzle tube 500, and the gas can blow off dust 600 attached to the filter tube 100 towards the filter cavity side, so as to realize cleaning of the filter tube 100.
