[0002] A filter is a device used for solid-liquid separation. It can intercept solid particles or contaminants suspended in liquids, thereby improving the purity of the liquid. This process is usually achieved through one or more filter media, such as filter paper, filter cloth, filter bags or porous materials. When the liquid passes through these filter media, the solid particles in it are intercepted, while the clean liquid flows out. The design of the filter varies depending on the application scenario. For example, in the chemical, food and beverage, water treatment and pharmaceutical industries, liquid filters need to be able to withstand different chemical properties and temperature conditions.

[0003] The patent document with application number CN201720609650.5 discloses a filter, which includes: a shell, the shell is a hollow cylindrical shape, an inlet pipe and a top outlet pipe are respectively arranged on both sides of the top of the shell, the inlet pipe is located on the top of the top outlet pipe, a sewage outlet is arranged on one side of the bottom of the shell, a bottom outlet pipe is arranged at the bottom of the shell, an external thread is arranged on the top of the shell, and the shell is made of resin material and is integrally formed; a cover plate, the cover plate can be connected to the top of the shell through the external thread; a filter bag, the filter bag is arranged inside the shell, and the horizontal height of the top of the filter bag is located at Between the inlet pipe and the top outlet pipe, the filtrate can enter the filter bag through the inlet pipe and be discharged from the filter through the top outlet pipe and / or the bottom outlet pipe. Based on the search of the above patent and in combination with the filter in the prior art, it is found that when the above filter is used, the filter is usually installed by bolt fastening connection and sealing buckle. However, the adjustability of this method is relatively low. Especially after the filter has been used for a long time, a large amount of dirt may accumulate inside the filter, and even cause unexpected situations such as blockage. These problems may affect the normal operation of the filter and reduce its working efficiency and filtering effect. Utility Model Content
