[0004] The technical solution adopted by this utility model to solve the above problems is as follows: the filter sealing ring clamping device includes a filter cylinder, a filter cover and a filter element. The filter element is installed inside the filter cylinder and the filter cover is installed on the filter cylinder. Its structural features are: a sealing seat is provided inside one end of the filter cylinder, and a sealing groove is provided on the sealing seat; a locking block is provided on the filter cover, and a first inclined surface is provided on the locking block; a sealing ring is provided at one end of the filter element, and a sealing block is provided on the sealing ring; a second inclined surface is provided on the sealing block; the locking block and the sealing block are both located in the sealing groove, and the first inclined surface is in contact with the second inclined surface.

[0005] Furthermore, a filter cartridge flange is provided on the outside of one end of the filter cartridge, and a filter cover flange is provided on the filter cover. The filter cartridge flange and the filter cover flange are connected by bolts.

[0006] Furthermore, the filter cartridge is provided with a discharge pipe at one end, the filter cover is provided with a feed pipe at one end, and the filter cover hopper is provided at the other end, with the filter cover hopper located inside the filter element.

[0007] Compared with the prior art, the present invention has the following advantages: both the card block and the sealing block are placed in the sealing groove, and the first inclined surface and the second inclined surface on the filter cover are pressed together. The filter element can be fixed by installing the filter cover. Therefore, when replacing the filter element, there is no need to fix the filter element separately, which makes it convenient to replace and install the filter element. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0018] Example

[0019] See Figures 1 to 5 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0020] The filter sealing ring clamping device in this embodiment includes a filter cylinder 1, a filter cover 2, and a filter element 3. The filter element 3 is installed inside the filter cylinder 1, and the filter cover 2 is installed on the filter cylinder 1. A sealing seat 12 is provided inside one end of the filter cylinder 1, and a sealing groove 14 is provided on the sealing seat 12. A locking block 24 is provided on the filter cover 2, and a first inclined surface 25 is provided on the locking block 24. A sealing ring 31 is provided at one end of the filter element 3, and a sealing block 32 is provided on the sealing ring 31. A second inclined surface 33 is provided on the sealing block 32. The locking block 24 and the sealing block 32 are both located inside the sealing groove 14, and the first inclined surface 25 is in contact with the second inclined surface 33.

[0021] In this embodiment, a filter cylinder flange 11 is provided on the outside of one end of the filter cylinder 1, and a filter cover flange 21 is provided on the filter cover 2. The filter cylinder flange 11 and the filter cover flange 21 are connected by bolts 4.
