Detailed Description

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail. As shown in fig. 1 and 2, an ash removal device for a ceramic filter element dust remover comprises a ceramic filter element 100, the ceramic filter element 100 is a hollow cylindrical structure, the ceramic filter element 100 comprises a first end 110 and a second end 120, the first end 110 is an opening, the second end 120 is funnel-shaped, the second end is further provided with an ash falling port 121, the ceramic filter element further comprises a blowing main pipe 200 and a blowing branch pipe 300 detachably mounted on the blowing main pipe, the first end 110 is fixed with a gland 111, the gland 111 is provided with a first through hole 112, and the blowing branch pipe 300 is driven by the first through hole 112 to enter an inner cavity of the ceramic filter element 100.

In one embodiment, as shown in fig. 1, the blow main tube 200 is disposed laterally above the side of the ceramic filter element 100. The blowing main pipe 200 comprises a main pipe 210 and branch pipes 220, the branch pipes 220 are fixed on the left side and the right side of the main pipe 210, the main pipe 210 is communicated with the inner cavities of the branch pipes 220, and a certain included angle is formed between the main pipe 210 and the branch pipes 220. The included angle ranges from 20 degrees to 90 degrees.

In one embodiment, as shown in fig. 1, the included angle ranges from 45 ° to 50 °, the blowing main pipe 200 is disposed laterally above the ceramic filter element 100, and unlike the conventional structure in which the blowing main pipe is disposed directly above the filter element, when the filter element needs to be replaced, the blowing main pipe does not need to be detached first, and then the filter element is detached, thereby reducing labor intensity. As shown in fig. 4, jetting is responsible for 1 and is set up directly over filter core or filter media in the traditional architecture, jetting in the equipment is responsible for 1 and filter core 3 and often has several rows, jetting is responsible for and is equipped with blowing nozzle 2 with the position that the filter core mouth corresponds, when one of them or several filter cores damage or need change, the jetting that is located directly over the filter core is responsible for the dismantlement that can obstruct the filter core, so at first will be responsible for whole the demolising back with the jetting, just can carry out subsequent filter core and demolish, in the large-scale dust collecting equipment, jetting is responsible for often great, heavy weight, it is very inconvenient to dismantle, labor intensity is great. In an embodiment, as shown in fig. 2, a first sealing ring 113 is further disposed between the pressing cover 111 and the first end 110, a second sealing ring 310 is sleeved and fixed on the blowing branch pipe 300, and the second sealing ring 310 seals the first through hole 112. The first sealing ring 113 and the second sealing ring 310 are arranged to prevent the gas blown into the ceramic filter element from being discharged from a place except the dust falling port, so that dust blown by the gas can only be removed from the dust falling port 121.

In one embodiment, as shown in figure 2, the purge leg 300 enters the interior cavity of the ceramic filter element along the central axis of the ceramic filter element 100.
