Embodiment Construction

[0019] like figure 1 , figure 2 and image 3 As shown, the liftable aeration device of the present invention includes an underframe 1 , an aeration pan 2 , a guide frame 7 , a lifting device and a roller guide device 8 . The aeration pan 2 is distributed on the underframe 1 and is connected with an air intake pipe (not shown in the figure), and the air intake pipe is connected with an air source on the ground. A guide frame 7 is respectively arranged on both sides of the underframe 1, and two guide grooves 9 are arranged on the guide frame 7. Self-locking grooves 10 are distributed on the bottom of the guide grooves 9. The self-locking grooves 10 are arc-shaped concave surfaces, and the guide grooves The section of 9 is U-shaped. A set of lifting devices are respectively installed on the guide frame 7 . Roller guide 8 is installed on the underframe 1, and its quantity is the same with guide groove 9, and cooperates with guide groove 9. During use, the guide frame 7 is in...

Abstract

The invention provides a liftable aeration device which comprises an underframe, an aeration disc, guide frames, lifting devices and rolling wheel guide devices, wherein the aeration disc is distributed on the underframe; the guide frames are respectively arranged on two sides of the underframe, and two guide grooves are arranged on the guide frames; the lifting devices are respectively mounted on two guide frames, each lifting device comprises a motor, a worm gear worm reducer, a gear, a rack, a lifting frame and a guide plate, the gears are meshed with the racks, and the racks are connected on the lifting frames; and the rolling wheel guide devices are mounted on the underframe, each rolling wheel guide device comprises a support saddle, a sleeve, a rolling wheel and a mounting frame, and the rolling wheels are positioned in the guide grooves of the guide frames. The lifting of the aeration device can be driven through the meshing between the gears and the racks, the lifting frames are simultaneously guided, and the floating rolling wheels are adopted as guide parts, thereby reducing the lifting resistance, simultaneously ensuring that the aeration device has no unbalance situation due to water flow impact during the lifting device and having the characteristics of stable and reliable lifting process and good positioning effect.

Description

technical field [0001] The invention relates to an aeration device in sewage treatment and belongs to the technical field of sewage treatment. Background technique [0002] In the sewage treatment process, the aeration tank is the main structure for aerobic treatment of sewage. Whether it is biological contact oxidation or activated sludge method, in order to maintain the life activities of microorganisms in the aeration tank during the treatment process, it is necessary to ensure that there is a certain amount of dissolved oxygen in the water. The so-called aeration refers to the use of an aeration device (such as an aeration plate) to continuously inject air into the water, or to use mechanical stirring to dissolve the oxygen in the air into the water. The former is mostly used in the activated sludge process. In the aeration tank of the activated sludge system, the aeration equipment is mostly arranged at the bottom of the tank. This arrangement can effectively play the...
