[0001] This utility model belongs to the field of disc filter technology, specifically a disc filter that is easy to assemble. Background Technology

[0002] Disc filters (also known as disc filters) are devices that achieve efficient deep filtration through multiple layers of grooved plastic discs. Their core design consists of multiple parallel-arranged filter units.

[0003] In the existing technology, disc filters require filter element replacement after a period of operation. However, the existing filter body is generally installed by threads. Repeated installation or removal of the threads can lead to stripping of the threads and leakage.

[0004] Therefore, this utility model provides a stacked filter that is easy to assemble. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems raised in the background art.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A conveniently assembled disc filter, comprising an inlet pipe and a three-way valve; one end of the three-way valve is connected to the inlet pipe via a flange, and another end of the three-way valve is connected to a drain pipe via a flange, and a bottom cover via a flange; an upper cover is installed on the bottom cover via an installation unit; a filter element is provided inside the bottom cover and the upper cover; the bottom end of the bottom cover is connected to an outlet pipe via a flange. In the prior art, disc filters require filter element replacement after a period of operation. However, existing filters are generally installed using threads, but repeated thread rotation during installation or disassembly can lead to thread stripping and leakage. Therefore, in this utility model, the filter element is an existing technology and will not be specifically described. During operation, the upper cover can be installed on or removed from the bottom cover via a concealed installation unit, facilitating filter element replacement and effectively preventing leakage due to thread stripping.

[0007] Preferably, the installation unit includes a first annular block; the first annular block is fixedly connected to the outer wall of the bottom cover; a first annular groove is formed on the first annular block; a set of arc-shaped L-shaped grooves are formed on the inner wall of the first annular groove, and the top of the arc-shaped L-shaped grooves is open; a second annular block is fixedly connected to the outer wall of the top cover; a fixing post is rotatably connected to the outer wall of the second annular block; during operation, the fixing post of the top cover and the second annular block is inserted into the opening of the arc-shaped L-shaped groove, and then rotated to move the fixing post into the horizontal groove of the arc-shaped L-shaped groove for limiting and fixing operation.

[0008] Preferably, a set of semi-circular annular grooves are formed on the outer wall of the bottom cover; annular rubber is fixedly connected to the inner wall of the semi-circular annular grooves; the annular rubber is hollow inside; a lower pressure plate is fixedly connected to the bottom of the first annular groove by a spring; a rubber bladder is provided between the lower pressure plate and the bottom of the first annular groove; the rubber bladder and the set of annular rubbers are interconnected by a hose; during operation, after the second annular block enters the first annular groove, the lower pressure plate is pressed down, causing the lower pressure plate to press down on the rubber bladder, and then the hose enters the annular rubber to inflate the annular rubber, filling the gap between the bottom cover and the top cover to ensure sealing.

[0009] Preferably, a circular groove is formed on the first annular block; the bottom end of the circular groove penetrates the arc-shaped horizontal groove of the L-shaped groove; a cylinder is provided in the circular groove; the cylinder is installed in the circular groove by a locking unit; a second annular groove is formed on the groove wall below the arc-shaped L-shaped groove.

[0010] Preferably, the locking unit includes a first groove; a pair of symmetrically distributed first grooves are provided on the outer wall of the cylinder; a locking block is fixed to the bottom of the first groove by a spring, and the end of the locking block is provided with a first inclined surface; a pull ring is provided at the top of the cylinder, and the bottom end of the pull ring is connected to the locking block by a pull wire.

[0011] Preferably, a second groove is formed at the bottom end of the cylinder; a support column is fixedly connected to the bottom of the second groove by a spring; and a disc is fixedly connected to the bottom end of the support column.

[0012] During operation, the cylinder is inserted through the through slot, and the locking block is inserted into the second annular groove. Then, the cylinder is limited by the disc and the support column to ensure stability. At the same time, when disassembling later, the locking block is retracted into the first groove by the pull ring, thereby releasing the locking column and allowing the second annular block and the top cover to rotate, thereby allowing the fixed column to disengage from the arc-shaped L-shaped groove and completing the disassembly operation.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The stacked disc filter described in this utility model is easy to assemble. The top cover can be installed on the bottom cover or removed from the bottom cover through a concealed mounting unit, which facilitates the replacement of the filter element and can effectively prevent water leakage due to slippage of the filter element.

[0015] 2. The stacked filter of this utility model, which is easy to assemble, presses down the pressure plate after the second annular block enters the first annular groove. The pressure plate presses down on the rubber bladder, and then the hose enters the annular rubber to inflate the annular rubber, filling the gap between the bottom cover and the top cover and ensuring a tight seal.
