Novel sewage stirring tank having regulating function

Abstract

The invention discloses a novel sewage stirring tank having a regulating function. The novel sewage stirring tank comprises a tank body and a water incoming pipe arranged at the upper end of the tankbody, a transverse plate capable of moving along the horizontal direction is arranged above the tank body, a second driving mechanism is arranged above the transverse plate and comprises an output shaft extending into the tank body, two stirring discs different in diameter are arranged on the output shaft, thickness of each stirring disc is gradually increased from inside to outside, a regulatingrod is arranged on each stirring disc, and one end of each regulating rod is connected with the corresponding stirring disc while the other end of the same is penetratingly inserted on the transverseplate; a moving block is arranged on the inner wall of the tank body and positioned below the water incoming pipe and can move on the inner wall of the tank body along the vertical direction, a waterdiversion plate is arranged on the side wall, facing the output shaft, of the moving block and connected with the moving block through a hinge, the moving block can rotate around the hinge, the waterdiversion plate is positioned below the water outgoing end of the water incoming pipe, and sewage in the water incoming pipe can flow onto the stirring discs through the water diversion plate.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a novel sewage mixing tank with regulating function. Background technique [0002] Urban sewage is a common water pollution. The urban sewage treatment process generally determines the degree of sewage treatment and the corresponding treatment process based on the utilization or discharge of urban sewage and the natural purification capacity of the water body. The treated sewage, whether used for Industry, agriculture, or groundwater recharge must meet the relevant water quality standards issued by the state. Sewage treatment tanks are one of the essential components of the sewage treatment system. According to different functions, sewage treatment tanks include filter tanks, sedimentation tanks, mixing tanks, reaction tanks and clear water tanks. When the mixing tank is used to treat sewage, flocculation technology is often used to treat sewage, so that the suspended p...

AI Technical Summary

Problems solved by technology

At present, in large-scale sewage mixing tanks, most of the existing mixing tanks are equipped with a stirring device in the center of the tank body, and the output end of the stirring device is provided with a stirring piece, which is used to stir the sewage in the tank However, the position of most of the stirring plates is fixed. Since the volume of sewage flowing into the mixing tank is not fixed, when there is a lot of sewage flowing into the pool, the stirring plate is located in the deep part of the sewage, and the sewage is stirred. However, the sewage in the upper layer cannot be stirred effectively; and when the sewage that is introduced is small, the stirring plate cannot stir the sewage when the stirring plate is not submerged, so that the sewage that is passed into the pool must be submerged in the stirring plate before it can be stirred. Stirring the sewage limits the normal use of the stirring device. At the same time, in a large stirring tank, the motors used in the stirring device are relatively large in size, which is inconvenient to adjust its height. Therefore, the existing large stirring tank It is impossible to effectively stir the sewage according to the volume of sewage passed into the pool body; and the existing sewage is sent into the pool body through the water inlet pipe installed on the inner wall of the pool body, because the water inlet pipe is close to the side of the pool body The inner wall makes the sewage gradually flow into the central position of the pool body from the inner wall close to the pool body, and after the sewage flows into the pool body, a part of the larger particles containing impurities will accumulate near the inner wall of the pool body, so the closer to the pool body The impurity concentration of the sewage at the inner wall of the pool is higher than that at the center of the pool body, and the stirring plate installed in the center of the pool body cannot effectively stir the sewage near the inner wall of the pool, so that the sewage near the inner wall of the pool The impurity-containing substances cannot be effectively mixed with the flocculant
