When the locking sleeve 6 is completely rotated to the inside of the inner recessed thread groove 201, the stabilizing layer 602 can tightly press against the outer ring of the opening of the water inlet and outlet ports 2, thereby playing a role of sealing and stabilizing the connection.

[0033] Connection of the water guide pipe 3 and the filter body 1

[0034] The water guide pipe 3 is used to guide the sewage into and out of the filter body 1. A limiting inner ring 4 is fixed on the inner wall of the water guide pipe 3, which can be made of plastic material and is used to limit the inserted connecting piece 5.

[0035] The connecting piece 5 and the water guide pipe 3 are connected through a fixing structure. The connecting piece 5 and the water guide pipe 3 are threadedly connected through fastening bolts 7 around the interfaces, which can be made of metal material to ensure the firmness of the connection. When the fastening bolts 7 are connected, the sealing rings 701 provided around the outer periphery thereof can be made of rubber material, which are inserted around the outer periphery of the interface of the connecting piece 5 to ensure the sealing property when the bolts are connected.

[0036] An arc-shaped guiding component guide 503 is connected to one end of the connecting piece 5 facing the limiting inner ring 4, which can be made of plastic material and can guide the insertion into the opening when the connecting piece 5 is butted to the ring interface of the limiting inner ring 4, thereby improving the smoothness of the butt joint.

[0037] A stabilizing ring body 401 is provided between the interface of the connecting piece 5 and the limiting inner ring 4, which can be made of rubber material to improve the stability.

[0039] Sewage filtering operation

[0040] The sewage enters the filter body 1 through the water guide pipe 3 at one end, and the sieve net 502 inside the connecting piece 5 intercepts the large impurities in the sewage during the entering process. The filtered sewage enters the filter body 1 for further treatment, and the treated water is guided out through the water guide pipe 3 at the other end.

[0041] II. Detailed working principle

[0042] Connection principle of the water inlet and outlet 2 and the water guide pipe 3

[0043] The inner concave thread groove 201 at the outer end of the water inlet and outlet 2 matches the outer thread of the locking sleeve 6. By rotating the rotating ring 601 on the locking sleeve 6, the locking sleeve 6 can be threadedly connected along the inner concave thread groove 201. When the locking sleeve 6 is completely rotated to the inside of the inner concave thread groove 201, the stable layer 602 glued to the inner end face of the rotating ring 601 tightly presses against the outer circle of the opening of the water inlet and outlet 2, achieving the purpose of sealing and stabilizing the connection.

[0044] Connection of the water guide pipe 3 with the connecting piece 5

[0045] The inner thread of the locking sleeve 6 matches the thread at the interface of the water guide pipe 3 and the connecting piece 5. Before installation, the locking sleeve 6 is first threadedly connected to the interface of the water guide pipe 3. After the water guide pipe 3 is connected to the connecting piece 5, the water guide pipe 3 is slowly rotated to connect the locking sleeve 6 to the connecting piece 5, and the outer thread of the locking sleeve 6 is connected to the inner thread of the inner concave thread groove 201, thereby assembling the water guide pipe 3 on the water inlet and outlet 2. This connection method can ensure sealing and does not require multiple bolts to be sequentially assembled, thereby improving installation efficiency.

[0046] Sewage filtration principle

[0047] When the sewage enters the filter, it first passes through the connecting piece 5. The sieve screen 502 in the connecting piece 5 intercepts large impurities in the sewage. Since the sieve screen 502 is made of stainless steel, it has certain strength and corrosion resistance, can effectively filter large-sized impurities, and prevent them from entering the inside of the filter body 1 to cause blockage. The filtered sewage enters the filter body 1 for further treatment, ensuring efficient operation of the entire sewage treatment process.

[0048] Connection stability and sealing principle

[0049] Connection stability of the connecting piece 5 and the water guide pipe 3

[0050] The connecting piece 5 and the water guide pipe 3 are connected by the fastening bolt 7, which ensures the firmness of the connection between the two. At the same time, during the connection process, the sealing ring 701 is inserted around the interface of the connecting piece 5 under the action of the fastening bolt 7, ensuring the sealing property of the connection between the two, preventing sewage leakage.

[0051] Stability of the connecting piece 5 and the limiting inner ring 4

[0052] In the process of connecting the connecting piece 5 and the limiting inner ring 4, the stable ring body 401 plays an important role. The clamping ball 402 at one end of the stable ring body 401 is inserted in the inside of the limiting inner ring 4, and the other end is inserted in the slot of the interface of the connecting piece 5. The stable ring body 401 is made of rubber material and has a certain elasticity, which can not only ensure the stability of the connection, but also facilitate replacement when needed. At the same time, the guiding part guide 503 on the connecting piece 5 can guide the insertion into the opening inside when it is connected to the ring port of the limiting inner ring 4, which improves the smoothness of the connection and further guarantees the stability and sealing performance of the whole device during operation.

[0053] The above is the working process of the whole device, and the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.
