Embodiment 1

[0020] Such as figure 1 The embodiment of the submersible mixer system of the present invention is given, which is suitable for the occasions where the bottom of the sewage pool is relatively flat and the pool depth of the sewage pool is relatively deep, mainly including the first submersible mixer 1 and the second submersible mixer 2, the first submersible mixer 1 and the second submersible mixer 2 are installed on the connecting piece 5, while the connecting piece 5 is installed on the guide rod 4, and can move up and down along the guide rod 4 to adjust the position, and can be tightened after adjusting the position. The connector 5 is fixed on the pool wall of the sewage pool through the guide rod 4, the guide rod 4 is perpendicular to the bottom of the pool, and installed against the pool wall, the position of the guide rod 4 is equal to the distance from the two sides of the pool wall. The axes of rotation shafts of the first submersible mixer 1 and the second submersibl...

Embodiment 2

[0023] Such as figure 2 As shown, another embodiment of the submersible mixer system of the present invention is given, which is suitable for the occasions where the bottom of the sewage pool is relatively flat, and the width of the sewage pool is relatively wide, and the bottom of the pool is not too deep. It mainly includes a first submersible mixer 1 and a second submersible mixer 2, the axis of rotation of the first submersible mixer 1 and the second submersible mixer 2 are parallel to the bottom plane of the sewage tank, and the first submersible mixer 1 and the second submersible mixer The height of the second submersible mixer 2 is the same, so as to stir the sludge mixed water in the pool in a wide range in the sewage tank, the first submersible mixer 1 and the second submersible mixer 2 are installed on the connecting piece 5, and are connected at the same time Part 5 is installed on the guide rod 4, and can move up and down along the guide rod 4 to adjust the positi...

Abstract

The invention relates to a submersible stirrer system for sewage treatment. The submersible stirrer system comprises a first submersible stirrer and a second submersible stirrer, wherein the axes of the rotating shafts of the first submersible stirrer and the second submersible stirrer are parallel with the surface of the bottom of a sewage pool; an installing plate is arranged at the bottom of the second submersible stirrer; a third submersible stirrer is arranged on the installing plate; the axis of the rotating shaft of the third submersible stirrer is arranged in a certain angle with that of the rotating shaft of the second submersible stirrer; and by additionally arranging the third submersible stirrer at the lower part of the second submersible stirrer, the sludge at the bottom of the sewage pool can be sufficiently stirred. According to the submersible stirrer system, the sludge at the bottom of the sewage pool can be specially stirred; and meanwhile, three submersible stirrers cooperate with each other, so the 360 DEG stirring effect of the sludge in a large-size sewage pool can be improved.

Description

technical field [0001] The invention relates to a mixer system for sewage treatment, which is suitable for occasions where the mixing effect of the sewage at the bottom of the pool is relatively high in a large sewage pool. Background technique [0002] As an important sewage treatment mixing machine, the submersible mixer is suitable for urban and rural sewage treatment plants, and is widely used in biochemical reaction tanks such as anaerobic tanks, sedimentation tanks and aeration tanks. The submersible mixer stirs the fluid in the sewage pool. In order to prevent the activated sludge rich in microorganisms from sinking to the bottom of the pool and keep it suspended in the pool, the fluid in the pool must be in motion. Generally, the fluid velocity in the pool is required to be greater than 0.1m / s, and The average speed is kept at about 0.3m / s, and the stirring effect is the best. In this state, the microorganisms fully react with the sewage to achieve mixing and stirri...
