Description

Technical Field

[0001] The utility model relates to the technical field of ceramic dust collectors, in particular to a fixing device for effectively protecting a ceramic filter element. Background Art

[0002] Ceramic filter dust collector is a new type of industrial purification equipment that relies on filtration to collect dust. Its working principle is: relying on the new filter material - the tiny pores of the porous ceramic filter element to collect and filter the dust in the flue gas, and then by cleaning the filter material to separate the dust accumulated on the filter element from the filter element, and then the conveying equipment transports the separated dust to the designated location. When the ceramic filter element and the flower plate are installed in the existing ceramic dust collector, the filter element flange is in hard contact with the flower plate, and when the dust collector shakes as a whole, it is easy to cause damage to the flange.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0016] See attached Figure 1 and 2 A fixing device for effectively protecting a ceramic filter element comprises a pressing plate 2, a venturi tube 3, a filter element 5 and a flower plate 8. The filter element 5 is inserted in the flower plate 8. A lower gasket 6 is sleeved between the filter element 5 and the flower plate 8. The venturi tube 3 is inserted in the filter element 5. The pressing plate 2 is arranged on the top of the filter element 5. An upper gasket 4 is arranged between the pressing plate 2 and the filter element 5. By installing the lower gasket 6, it is ensured that the flange of the filter element does not have hard contact with the flower plate 8 when pressed. By installing the upper gasket 4, it is ensured that the pressing plate does not have hard contact with the filter element. When the dust collector is blown and shaken as a whole, the lower gasket 6 and the upper gasket 4 can increase the elastic space, thereby ensuring that the pressing plate 2 does not have hard contact. Example

[0017] See attached Figure 3 and 4Based on the first embodiment, a plurality of filter holes 10 are provided on the flower plate 8, and a limiting annular groove 11 is provided at the filter hole 10. The lower gasket 6 is located in the limiting annular groove 11, and an anti-slip pattern 12 is provided at the bottom of the limiting annular groove 11. The lower gasket 6 contacts the anti-slip pattern 12, so that the lower gasket 6 can be limited, and the installation efficiency is improved. In addition, the existence of the anti-slip pattern 12 increases the friction between the lower gasket 6 and the flower plate 8, and improves the stability;

[0018] The upper gasket 4 and the lower gasket 6 are composed of a first ceramic gasket 13, a high temperature resistant soft pad 15 and a second ceramic gasket 14 arranged from bottom to bottom. The high temperature resistant soft pad 15 is adhered between the first ceramic gasket 13 and the second ceramic gasket 14. Figure 4 As shown, the overall elasticity of the upper gasket 4 and the lower gasket 6 is improved by adding the high temperature resistant soft pad 15, and in this embodiment, the high temperature resistant soft pad 15 is made of silicone rubber material, which is resistant to high temperatures and has good toughness. Example

[0019] Based on the above-mentioned embodiment one or two, threaded columns 9 are installed at the four corners of the flower plate 8, and spacer threaded tubes 7 are threadedly connected on the threaded columns 9. Bolts 1 are provided at the four corners of the pressure plate 2, and the bolts 1 are threadedly connected in the spacer threaded tubes 7. When used specifically, first place the lower gasket 6 in the limiting annular groove 11, and then insert the filter element 5 into the filter element hole 10 of the flower plate 8, press the lower gasket 6 down at the flange of the filter element 5, and then insert the Venturi tube 3 in the filter element 5, place the upper gasket 4 on the top of the filter element 5, and finally cover the pressure plate 2, and then connect the pressure plate 2 and the flower plate 8, thread the spacer threaded tube 7 on the threaded columns 9, and then thread the bolts 1 into the spacer threaded tube 7.
