Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to an improved scum filtration device. Background Technology

[0002] According to publication number CN222033790U, patent title: "A Scum Filtering Device," when the scum collection box is submerged in water, its internal limiting groove may directly contact the water, allowing floating debris on the water surface to come into contact with the limiting groove. When the lifting mechanism pulls the scum collection box, the floating debris may contaminate the limiting groove, making the maintenance and cleaning of the device complex and difficult. Therefore, we propose an improved scum filtering device. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] In view of the shortcomings of the prior art, this utility model provides an improved scum filtration device, which overcomes the shortcomings of the prior art, has a reasonable design and compact structure, and solves the problems mentioned in the background art.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An improved scum filtration device includes a sliding sleeve with a through groove for a lifting chain to pass through. The lifting chain includes multiple chain teeth connected end-to-end by a connecting rod, with the chain teeth extending to the tail ends on both sides. The chain teeth form an inclination angle with the connecting rod. A sliding block corresponding to the chain teeth is slidably disposed on the sliding sleeve. A spring connected to the sliding block allows the sliding block to extend and retract to remove scum from the chain teeth.

[0008] Preferably, the inner sidewall of the bottom of the sliding sleeve has an inwardly recessed groove, along which the sliding block can slide.

[0009] Preferably, the angle formed by the chain teeth and the connecting rod is an acute angle.

[0010] Preferably, an inclined surface is provided on the bottom of the sliding block, and the inclined surface of the sliding block corresponds to the inclined surface of the chain teeth.

[0011] Preferably, a limiting block is also hinged to the sliding sleeve, and the limiting block extends towards the inclination angle of the chain teeth to limit the lifting chain.

[0012] Preferably, the limiting block has several drainage holes for water to flow out of the lifting chain, and the base of the limiting block also has an arc-shaped surface that extends into the groove of the sliding sleeve to guide the water.

[0013] (III) Beneficial Effects

[0014] This utility model provides an improved scum filtration device. It has the following beneficial effects:

[0015] 1. The sliding block is connected to the sliding sleeve by a spring and can extend and retract, so that when the lifting chain moves, the sliding block can automatically remove the floating debris on the chain teeth.

[0016] 2. Several drainage holes are provided on the limiting block. When the lifting chain is raised, the water adhering to the surface can flow out along the drainage holes, which prevents water from flowing into the cavity where the limiting block is stored, thereby reducing the accumulation of pollutants.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See attached document Figure 1-5An improved scum filtration device includes a sliding sleeve 1. The sliding sleeve 1 has a through groove for a lifting chain 3 to pass through. The lifting chain 3 includes multiple chain teeth 31 connected end-to-end by a connecting rod, with the chain teeth 31 extending to both sides at their tails. The chain teeth 31 form an angle with the connecting rod, and this angle is acute. A sliding block 12 corresponding to the chain teeth 31 is slidably mounted on the sliding sleeve 1. A spring 13 connected to the sliding block 12 allows the sliding block 12 to extend and retract, thus removing scum from the chain teeth 31. 2. The sliding block 12 is connected to the sliding sleeve 1 by the spring 13 and can move telescopically. When the lifting chain 3 moves, the sliding block 12 can automatically remove the scum on the chain teeth 31. The bottom of the sliding block 12 is provided with an inclined surface, which corresponds to the inclined surface of the chain teeth 31. This design allows the scum to be effectively scraped off during the relative movement of the sliding block and the chain teeth, avoiding the accumulation of scum on the chain teeth. The bottom inner wall of the sliding sleeve 1 has an inwardly recessed groove 11, along which the sliding block 12 can slide.

[0025] Furthermore, a limiting block 2 is hinged to the sliding sleeve 1. The limiting block 2 extends towards the inclined angle of the chain teeth 31 to limit the lifting chain 3, thereby preventing the lifting chain 3 from swinging and improving the stability of the device. When the lifting chain 3 is lifted, the water adhering to its surface will flow downwards along the lifting chain 3. In order to prevent the water on the chain teeth 31 from flowing into the cavity where the limiting block 2 is stored, the limiting block 2 is provided with several drainage holes 22 for the water on the lifting chain 3 to flow out. The base of the limiting block 2 is also provided with an arc-shaped surface 21, which extends towards the through groove of the sliding sleeve 1 to guide the water, thereby preventing the water from flowing into the cavity where the limiting block is stored and reducing the accumulation of pollutants.
