Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

Referring to fig. 1 to 4, the present invention discloses an assembled filter cartridge structure, which comprises a cylindrical net pipe 1, a filter material cylinder 2 and two end covers 3, wherein the filter material can be a folding filter material. Each end cover fixed connection is at the both ends of drum network management 1, the utility model discloses in, the center of end cover 3 sets up a circle through-hole 31, and the periphery of end cover 3 is provided with round outward flange 32, and the periphery of circle through-hole 31 is provided with round inward flange 33, and the inner wall of inward flange 33 is provided with internal thread 34. When the end cover 3 is installed, the outer wall of the inner flange 33 is fixedly connected to the cylindrical mesh pipe 1, and welding can be performed. The outer flange 32 and the inner flange 33 are arranged in the same direction, a mounting groove 35 capable of connecting two ends of a filter material is formed between the outer flange 32 and the inner flange 33, and the mounting groove 35 can block the filter material barrel body 2 from falling.

When two filter cylinders are required to be combined and connected, the two end covers 3 of two adjacent filter cylinders can be connected through a threaded pipe 4, and the threaded pipe 4 is a hollow pipe so as to ensure the air circulation between the two filter cylinders. The outer diameter of the threaded pipe 4 corresponds to the inner diameter of the circular through hole 31, and the outer wall of the threaded pipe 4 is provided with an external thread 41 which can be matched with the internal thread 34 on the end cover 3. A high-temperature-resistant gasket 5 is arranged between the two connected end covers 3, and the high-temperature-resistant gasket 5 is positioned between the bottom surfaces of the two mounting grooves 35. The length of the threaded pipe 5 is larger than the sum of the lengths of the inner flanges of the two end covers 3, and even the length of the threaded pipe can be longer, so that the threaded pipe 5 can be connected with the inner sides of the two end covers 3 to form a connecting effect. When the assembly is needed, the threaded pipe 5 can be connected to one end cover 3, the high-temperature-resistant sealing gasket 5 is sleeved on the threaded pipe, and then the internal thread 34 of the end cover 3 of the other filter cylinder is assembled on the threaded pipe 5 and screwed tightly. In order to overcome the problem that the threaded pipe can be directly rotated into the same end cover when the threaded pipe rotates for the second time, a resisting part is convexly arranged at the middle part of the threaded pipe 5, so that the outer side surface of the resisting part forms an anti-skidding surface, and the resisting part resists against the outer side of the round through hole 31 and is positioned on the bottom surface of the mounting groove 35. In order to avoid the high temperature resistant gasket 35 from being affected, the thickness of the blocking portion is smaller than that of the high temperature resistant gasket, and a relief notch (not shown in the figure) for accommodating the blocking portion is formed on the inner side of the high temperature resistant gasket. In this embodiment, the two ribs 42 are formed on the outer wall of the threaded pipe, and the upper and lower surfaces of the ribs 42 are provided with a plurality of anti-slip protruding particles to increase friction force, so that the ribs 42 have an anti-slip effect when being attached to the surface of the end cover 3.

In order to match the use of the filter cartridge, a screw cap 6 can be further matched on the end cover 3, as shown in fig. 4, the outer periphery of the screw cap is provided with an external thread 61 matched with the internal thread 34 on the end cover 3, the screw cap 6 can form a sealing cap body or a cap body with a vent hole, and a sealing ring can be added between the screw cap and the round through hole.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
