Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a paddle mixer for sewage treatment. Background Art

[0002] In sewage treatment, the paddle mixer is mainly used for sewage agitation to fully mix the sewage with the added flocculant. The paddle mixer is mainly composed of a motor, a rotating rod and a stirring blade.

[0003] For example, the authorization announcement number CN218688622U provides a water treatment paddle mixer, including a motor, a stirring shaft and a stirring paddle, the stirring paddle is composed of a shaft sleeve and a paddle, the shaft sleeve is arranged on the stirring shaft and is slidably connected thereto, the lower end surface of the paddle is provided with a reinforcing rib, the side end surface of the shaft sleeve is provided with an adjusting groove, the bottom of the adjusting groove is provided with a screw hole, a fastening bolt is provided in the screw hole, and a waterproof cover is provided in the adjusting groove. By providing a slidingly connected waterproof cover structure on the fastening bolt, the waterproof cover can shield the fastening bolt during the use of the stirring paddle, so as to prevent the fastening bolt from contacting with external sewage, thereby preventing the fastening bolt from rusting and being unable to be screwed out, thereby affecting the height adjustment of the stirring paddle, and by providing an arc-shaped reinforcing rib on the back of the paddle, the structural strength of the paddle is improved, and the resistance is small, which will not cause sludge to accumulate in dead corners, but the paddle mixer has the following disadvantages during use:

[0004] The paddle mixer involves adjusting the paddle blades up and down. During the specific up and down adjustment process, the paddle can slide on the stirring shaft by loosening the fastening bolts. After adjusting to a suitable height, the fastening bolts are tightened. However, when the paddle blades are stirring sewage, the paddle blades are in the sewage. When personnel need to adjust the height of the paddle blades, if the situation is urgent, they need to dive into the sewage to loosen the fastening bolts to adjust the height of the paddle blades. The operation is difficult and inconvenient for personnel to operate. Therefore, the utility model provides a paddle mixer for sewage treatment. Utility Model Content
