A kind of alum feeding device for sewage treatment

Abstract

The invention discloses an alum dispensing device for sewage treatment, which comprises a dispensing machine and a storage box installed on the top of the dispensing machine. The storage box is provided with a storage cavity, and the bottom of the storage cavity is connected with a conical cavity arranged downwardly. The extension part at the bottom of the conical cavity extends into the feeding machine, and the feeding machine at the bottom of the conical cavity is provided with a connecting hole extending downward. Through the feeding port on the bottom surface of the feeding machine, the side of the connecting hole adjacent to the tapered cavity is provided with a sliding chamber extending left and right. The sliding chamber is equipped with a transportation control device, and the inner walls of the left and right sides of the feeding groove are equipped with guides. There are embedded grooves in the inner bottom wall of each guide groove, and a screening plate is slid and connected between the guide grooves on the left and right sides; the present invention is simple in structure, easy to operate, can automatically refine work, and improves Delivery efficiency and delivery uniformity reduce waste.

Description

technical field [0001] The technical field of sewage treatment of the present invention relates to an alum feeding device for sewage treatment. Background technique [0002] Industrial production and residents’ daily life will produce a large amount of sewage. If the sewage is discharged directly into creeks and rivers without treatment, the water quality and environmental landscape will be seriously affected. And through other procedures, finally discharged into the river. The existing alum feeding method adopts manual feeding, which cannot effectively control the feeding amount. Too much feeding will cause waste, and too little feeding will not be able to achieve the desired effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an alum dosing device for sewage treatment, which can solve the above-mentioned problems in the prior art. [0004] The present invention is achieved through the following technical ...
