Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a chain plate type scraper sprocket tensioning device. Background Art

[0002] With the rapid development of cities, sewage treatment plants have become essential infrastructure for urban development and construction. Sedimentation tanks are a key component of activated sludge sewage treatment technology. They are generally used to settle suspended solids or activated sludge in sewage to achieve water clarification. Horizontal flow sedimentation tanks are the most commonly used sedimentation tanks. These tanks are highly stable, simple to design and construct, and capable of long-term stable operation, making them widely used in sewage treatment plants.

[0003] The equipment in the sedimentation tank includes chain scrapers, skimmers, outlet chutes, etc. The circumference of the chain scraper chain is usually twice the length of the sedimentation tank. Since there will be gaps and wear in the chain during installation and operation, and the chain itself has a certain degree of ductility, the chain will gradually become loose as the running time increases.

[0004] In view of the problems existing in the prior art, a device is needed to solve the problem of chain extension and loosening, so as to solve the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides a chain plate type scraper sprocket tensioning device, comprising:

[0006] An adjustment plate is used to install the scraper sprocket. The adjustment plate is equipped with fixing bolts, which are used to connect with the assembly part of the sprocket to fix the sprocket. The adjustment plate is provided with a long hole for installing the bolt and fixing the adjustment plate to the wall.

[0007] The support plate is used to provide support force during adjustment. It is installed on the wall and is in the same plane as the adjustment plate. The support plate is a right-angled triangle structure with fixing holes on the bottom surface and adjustment holes on the side surface;

[0008] The tensioning structure is used to adjust the position of the adjusting plate, thereby tensioning the sprocket. The tensioning structure includes an adjusting bolt and an adjusting nut. One end of the adjusting bolt is fixedly mounted on the adjusting plate through a protrusion, and the other end passes through the adjusting hole of the support plate. The adjusting nut is threadedly mounted on the adjusting bolt. Two adjusting nuts are provided and are respectively arranged on both sides of the support plate.

[0009] As a preferred solution of the present invention, a washer and a gasket are provided between the adjusting nut and the support plate.

[0010] As a preferred scheme of the utility model, the long hole is equidistantly provided with four, and the long hole is used for adjusting the installation position of the adjusting plate.

[0011] As a preferred scheme of the utility model, the fixed bolt is provided with two M24 bolts.

[0012] As a preferred scheme of the utility model, the fixing hole of the supporting plate is symmetrically provided with two.

[0013] As a preferred scheme of the utility model, the adjusting plate and the supporting plate are both made of stainless steel 304.

[0014] Due to the above technical scheme, the utility model has the following beneficial effects:

[0015] The utility model discloses a tensioning structure of chain plate type mud scraper chain wheel, which realizes effective tensioning of the chain wheel, solves the problem of chain extension and loosening, and further meets different tensioning requirements. ACCURATE DRAWINGS

[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model.

[0020] Embodiment 1

[0021] As Figure 1 , Figure 2As shown, a specific embodiment of a chain plate type scraper sprocket tensioning device described in the utility model includes: an adjusting plate 1, a support plate 2 and a tensioning structure 3. A fixing bolt 5 is installed on the adjusting plate 1 for fixing the sprocket. Four equidistant long holes 4 are also provided on the adjusting plate 1 for installing bolts and fixing the adjusting plate 1 to the wall. The support plate 2 is a right-angled triangle structure with two symmetrical fixing holes on the bottom surface and an adjustment hole on the side. The tensioning structure 3 includes an adjusting bolt 6 and an adjusting nut 7. One end of the adjusting bolt 6 is fixedly installed on the adjusting plate 1 through a protrusion 8, and the other end passes through the adjustment hole of the support plate 2. The adjusting nut 7 is threadedly installed on the adjusting bolt 6 and is respectively arranged on both sides of the support plate 2. In addition, a washer and a gasket are provided between the adjusting nut 7 and the support plate 2 to enhance the stability and reliability of the connection.

[0022] The fixing bolts 5 are set to two M24 bolts, and the adjustment plate 1 and the support plate 2 are both made of stainless steel 304.

[0023] The working principle of the present invention is as follows: when in use, first fix the support plate 2 on the wall through the fixing hole and make it in the same plane as the adjusting plate 1; then, install the sprocket on the adjusting plate 1 and fix it with the fixing bolt 5; then, by adjusting the position of the adjusting plate 1 in the long hole 4 and rotating the adjusting nut 7 on the adjusting bolt 6, the sprocket can be effectively tensioned; when the chain extends and becomes loose, the adjusting nut 7 can be adjusted to make the adjusting bolt 6 pull the adjusting plate 1, thereby subjecting the sprocket to tensioning force, thereby achieving the purpose of tensioning the chain.
