Description
Technical Field
[0001] The utility model relates to the technical field of filter elements, in particular to a rotary backwashing assembly for regenerating a dust removal filter element. Background Technique
[0002] The filter element is installed in the filter. The gas enters the inside of the filter element through the outer surface of the filter element and then flows out from the upper part. Since the filter element has the functions of filtering and blocking impurities. During the filtering process, more and more impurities accumulate on the outer surface of the filter element. For this reason, common filter elements all have the function of backwashing. Backwashing is to introduce clean gas into the upper part of the filter element, and use the clean gas to blow from the inside of the filter element to the outside, blowing the impurities accumulated on the outside of the filter element outwards, so that the impurities are separated from the filter element. For the existing backwashing assembly, due to the use of a fixed blowing method, the effect of removing impurities on the surface of the filter element is poor. For this reason, people have carried out a lot of research. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a rotary backwashing assembly for regenerating a dust removal filter element, which can solve the problems in the above-mentioned current technology.
[0004] The utility model is realized by the following technical solutions: A rotary backwashing assembly for regenerating a dust removal filter element of the utility model includes a filter element ring buckle pressing plate. A telescopic sleeve is arranged inside the filter element ring buckle pressing plate. It is characterized in that a sleeve is sleeved outside the telescopic sleeve, and the sleeve is rotationally and cooperatively connected with the telescopic sleeve. Guide pipes are arranged on the left and right sides of the sleeve, and an air pipe is arranged at the bottom of the guide pipe. A plurality of air holes are arranged inside the air pipe. A bracket assembly is arranged outside the telescopic sleeve. The telescopic sleeve and the air pipe rotate around the bracket assembly. A filter element assembly is clamped inside the bracket assembly. The filter element assembly includes a filter element. The air pipe is arranged inside the filter element. A first bracket is arranged outside the backwashing air interface rod.
[0005] A further technical solution is that a top ring is arranged at the top of the filter element, and a bottom plate is arranged at the bottom of the top ring.
[0006] A further technical solution is that a plurality of fixing frames are arranged on the outer surface of the air pipe. A fixing rod is arranged in the middle of the fixing frame. The fixing rod is fixedly and cooperatively connected with the telescopic sleeve. A base assembly is arranged at the bottom of the fixing rod.
[0007] The base assembly includes a bottom plum blossom nut. A rotating hole is arranged inside the bottom plum blossom nut. A rotating rod is arranged at the bottom of the fixing rod. The rotating rod is inserted into the rotating hole and rotates in the rotating hole. A bottom sealing gasket is arranged at the top of the bottom plum blossom nut. The rotating rod passes through the bottom sealing gasket.
[0008] Further technical solution: The bracket assembly includes a plurality of second brackets arranged around the first bracket. A clamping structure for clamping the filter element assembly is arranged on the lower side of the second bracket. A connection structure for enabling the telescopic sleeve to rotate within the first bracket is arranged between the first bracket and the telescopic sleeve.
[0009] Further technical solution: The clamping structure includes a third bracket. A fourth bracket is arranged on the upper side of the third bracket.

[0013] Further technical solution: Upper and lower nuts are in threaded fit connection with the outer surface of the anti-blowing interface rod. The upper and lower nuts respectively abut against the upper and lower end faces of the first bracket.
[0014] The beneficial effects of the present utility model are as follows:
[0015] 1. The anti-blowing assembly adopts the method of rotary anti-blowing and is applicable to large-diameter filter elements. Compared with the traditional single-orifice anti-blowing, most dead zones of large-diameter filter elements cannot be reached by anti-blowing, and most of the dust and impurities attached to the surface of the filter element cannot be blown off, resulting in low anti-blowing efficiency. This anti-blowing assembly can penetrate into the interior of the filter element. By arranging an air pipe and air holes, the bracket structure composed of the fixing rod, fixing frame, air pipe, conduit, telescopic sleeve, and anti-blowing interface rod can rotate 360° evenly for anti-blowing, and the separation of impurities attached to the surface of the filter element is obvious, with high anti-blowing efficiency.
[0016] 2. When arranging the air holes on the air pipe, the air holes can be set to open towards the left or right, so that the central axis of the air hole does not pass through the center of the circular trajectory formed after the movement of the air pipe and forms a certain included angle, so that the gas ejected forms a driving force to enable the bracket structure composed of the fixing rod, fixing frame, air pipe, conduit, telescopic sleeve, and anti-blowing interface rod to rotate 360°, and the air holes need to blow towards the filter element.

[0027] Beneficially, a threaded portion is arranged on the outer surface of the bottom plum blossom nut 36. The threaded portion passes through the filter element housing and is in threaded cooperation connection. The filter element housing refers to the housing for installing this assembly and the filter element, so that the bottom plum blossom nut 36 is fixed in the housing. The bottom sealing gasket 35 serves to seal the threaded hole in the filter element housing that cooperates with the bottom plum blossom nut 36.
[0028] Beneficially, the support assembly includes a plurality of second supports 17 arranged around the first support 15. A clamping structure for clamping the filter element assembly is arranged on the lower side of the second support 17. A connection structure for enabling the expansion sleeve 12 to rotate inside the first support 15 is arranged between the first support 15 and the expansion sleeve 12.
[0029] Beneficially, the clamping structure includes a third support 11. A fourth support 42 is arranged on the upper side of the third support 11.

The upper and lower nuts 13 and 52 respectively abut against the upper and lower end faces of the first bracket 15.
[0032] When the component filters gas, the dirty gas in the external space flows from the outside of the filter element 43 towards the inside of the filter element 43. The filter element 43 functions to block the impurities in the dirty gas.

Thereafter, since the sleeve 23 is rotatably sleeved on one side of the telescopic sleeve 12, on the one hand, since the reverse blowing interface rod 14 passes through the first bracket 15 and the rotating rod 34 at the bottom of the fixing rod 22 is rotatably engaged with the rotating hole 51, the bracket structure can rotate freely. Clean gas is introduced into the reverse blowing interface rod 14 and the telescopic sleeve 12. The gas flows along the reverse blowing interface rod 14, the telescopic sleeve 12, the conduit 18 and the trachea 19, and is ejected outward from the pores of the trachea 19 and diffuses from the inside to the outside of the filter element 43, blowing off the impurities accumulated on the outer surface of the filter element 43. Due to the pressure of the gas, when the gas blows obliquely at the pores, the bracket rotates, and 360° uniform reverse blowing can be realized, so that the impurities attached to the filter element 43 are fully separated from it.

Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
