Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to an easily disassembled and assembled folded filter element. Background Art

[0002] Filter element is a professional term for filtering and purification functions. It is a simple device for separating resources and resources to purify the original fluid.

[0003] A currently used easy-to-disassemble foldable filter element has been searched and found, for example, in a Chinese patent document with an authorization publication number of CN210434116U, an easy-to-disassemble foldable filter element is disclosed, including a pipeline, a top cover, a bottom plate, a filter element body, a clamping plate, a non-slip soft rubber pad, a sealing ring, a clamping rod, a fixed plate, a rotating block and a mounting sleeve, wherein the filter element body is mounted on the right end face of the bottom plate, the top cover is mounted on the right end face of the filter element body, the right end face of the top cover is connected to the pipeline, the fixing plates are symmetrically mounted on the upper and lower sides of the right end face of the top cover, the left sleeve of the annular side face of the pipeline is provided with a sealing ring, the right end face of the top cover is connected to the sealing ring, the fixing plate is mounted inside the mounting plate, the clamping rod is mounted inside the mounting sleeve, the rotating block is fixed on the upper end face of the clamping rod, the clamping plate is mounted on the lower end face of the clamping rod, and the non-slip soft rubber pad is bonded to the lower end face of the clamping plate. This design solves the problem that the original filter element is laborious to install and disassemble and lacks mobility and flexibility. The utility model has a reasonable structure, is easy to combine and install, is flexible to use, and is simple to operate.

[0004] Although the above patents solve the problems in the above-mentioned background technology, they still have the following shortcomings: 1. The filter element uses a clamping rod to clamp the anti-slip soft rubber pad and the pipe. This clamping method only relies on friction to install the filter element, and its fixing effect is low. Therefore, when in use, it is easy to cause the filter element and the pipe to shift, which is not conducive to subsequent filtering operations; 2. The folded filter cloth cannot be adjusted in the filter element, so that the filter cloth is in a loose state, which affects the filtering effect of the filter element and reduces the practicality of the filter element.

[0005] In summary, the utility model solves the problems in the above-mentioned background technology by designing an easily disassembled folded filter element. Utility Model Content

An adjusting knob 1051 is fixedly installed at the bottom of the adjusting screw 105.

[0029] Specifically, the top end of the piston rod 103 fits through the bottom surface of the piston cylinder 104 and extends inwardly, the top surface of the piston cylinder 104 contacts the bottom surface of the top cover 101, there are multiple piston rods 103, and the multiple piston rods 103 are distributed in an annular manner with equal distances about the top surface of the bottom cover 102, the inner surface of the filter element body 1 contacts the outer surface of the piston cylinder 104, and it is formed by folding a fine polypropylene fiber membrane and a non-woven fabric in one piece, and the top thread of the adjusting screw 105 passes through the bottom surface of the bottom cover 102 and is rotatably connected to the bottom surface of the top cover 101 through a bearing;

[0030] In this embodiment, the setting of the adjusting knob 1051 is mainly used to drive the adjusting screw 105. Under the threaded cooperation between the adjusting screw 105 and the bottom cover 102, the bottom cover 102 gradually drives the filter element body 1 to move downward, and the setting of the piston cylinder 104 is mainly used to fit and slide with the piston column 103, thereby achieving the effect of smooth movement of the bottom cover 102, facilitating the unfolding of the folded filter cloth in the filter element body 1, and improving the filtering effect of the filter element.

[0031] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The disassembly and assembly mechanism 3 includes a mounting seat 301 and an annular block 302. The mounting seat 301 is fixedly sleeved on the outer bottom end of the pipe 2, and an annular groove 303 is provided on the bottom surface thereof. A guide screw 304 is rotatably provided on the outer surface of the mounting seat 301, and a guide block 305 is sleeved on the outer side of the guide screw 304.

The annular block 302 is fixedly installed on the top surface of the top cover 101, and an insertion hole 308 is provided on the outer side thereof.

[0032] Specifically, a sealing gasket is provided on the inner side of the annular block 302, and it is in sealing contact with the annular groove 303 through the sealing gasket.

The guide screw 304 starts to rotate, and the guide block 305 moves and drives the insertion rod 306 to approach the socket 308 until the insertion rod 306 is plugged into the socket 308, so that the top cover 101 and the pipe 2 are fixed, thereby completing the installation of the filter element. Otherwise, the filter element can be disassembled, thereby improving the practical effect of the filter element.
