Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a screen for a filter and the filter thereof. Background Technology

[0002] A sieve is a mesh material used for screening, filtering, or classifying solid particles. It is widely used in many fields such as industry, agriculture, mining, food processing, construction, and environmental protection. A sieve used for filters is a mesh material specifically designed to filter solid particles in liquids or gases. This type of sieve plays an important role in many fields such as industry, environment, food processing, medicine, and laboratories.

[0003] Existing filter screens require insertion into the mounting box via a sliding groove until they reach the desired position. Then, the threaded column is rotated to move the screen into the fixing hole, securing it for material screening. After screening, cleaning is required; the threaded column is then rotated out of the fixing hole, and the screen is ejected by the second spring for cleaning or replacement. Compared to traditional fixing structures, this external fixing structure prevents material from falling into the mounting box and causing waste, and also prevents dust from contaminating the interior. However, existing filter screens rely on the second spring's elasticity to eject the screen. Over time, the spring is prone to fatigue, leading to reduced or failed elasticity, potentially resulting in insufficient ejection force or even failure to eject the screen. This necessitates frequent spring replacements, increasing maintenance costs.

[0004] Therefore, it is necessary to provide a new type of screen for filters and a filter thereof to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a screen for a filter and a filter thereof.

[0006] The present invention provides a screen for a filter, comprising an installation housing and a screen body, wherein the screen body is detachably connected to the inner wall of the installation housing via several connecting devices. The connecting device includes two connecting outer rings I, two connecting outer rings II, several limiting components, several connecting inner rings, and a fixing frame. The fixing frame is fixedly connected to the outer surface of the mounting housing. Both connecting outer rings I are detachably connected to the inner wall of the fixing frame. Both connecting outer rings II are detachably connected to the top of the screen body through fixing blocks. The several connecting inner rings are respectively fixedly connected to the inner walls of the two connecting outer rings I and the two connecting outer rings II. Sliding holes are provided on the several connecting inner rings, the two connecting outer rings I, and the two connecting outer rings II.

[0007] Preferably, the limiting component includes a limiting plate, which is slidably connected to the inner wall of a groove on the inner connecting ring, and a driving plate is fixedly connected to one side wall of the limiting plate. The driving plate is slidably connected to the inner wall of a sliding hole on the inner connecting ring, the first connecting ring, and the second connecting ring.

[0008] Preferably, a lever is fixedly connected to the top of the drive plate, and rubber anti-slip particles are provided on the outer surfaces of both the drive plate and the lever.

[0009] Preferably, a handle is fixedly connected to the top of the mounting housing.

[0010] Preferably, the inner wall of the mounting housing is provided with a groove for moving the screen body, and one side wall of the mounting housing is provided with a through hole for placing the screen body.

[0011] The second aspect of this utility model provides a filter including a screen for the filter and a filter housing, wherein the fixing frame is detachably connected to the inner wall of the filter housing.

[0012] Compared with related technologies, the screen and filter provided by this utility model have the following advantages: With the designed connecting device, when the screen body needs to be installed, it is first moved into the mounting housing through the through-hole. When the screen body is in the designated position, the drive plate is rotated by the lever. The drive plate will cause the limiting plate to slide on the inner wall of the groove on the connecting inner ring. Then, the limiting plate limits the connecting inner ring and the connecting outer ring, thereby installing the screen body. This device reduces the probability of spring fatigue after long-term use, which may lead to elasticity decay or failure, resulting in insufficient screen ejection force or even failure to eject, requiring frequent spring replacement, thus reducing maintenance costs.
