Description

Technical Field

[0001] This utility model relates to the field of waste gas collection technology for sewage treatment ponds, and specifically to a waste gas collection device for sewage treatment ponds. Background Technology

[0002] Secondary pollutant exhaust gases from wastewater treatment plants in chemical enterprises are characterized by strong odors and difficulty in collection, making them a key target for collection and treatment by enterprises. Currently, the most common wastewater treatment plant exhaust gas collection method in engineering is to collect the exhaust gases by covering the top of the pool, mainly using inverted membrane covers, etc. This method mainly utilizes fiber membranes and steel frames erected on the top of the pool, with pre-embedded bolts used to fix the membrane to the top of the pool.

[0003] Existing technologies have complex structures, complicated installations, and cumbersome opening methods. Therefore, a waste gas collection device for sewage treatment ponds is proposed, which has a convenient opening method in the later stages. Utility Model Content

L-shaped brackets are installed on the outer side of the top of the support frame. The top of the sealing frame is equipped with a collection cover, and lifting brackets are provided on both sides of the collection cover. The top of the L-shaped brackets is equipped with hydraulic cylinders by bolts, and a collection hose is connected to one side of the top of the collection cover through a reserved hole.

[0006] By adopting the above technical solution, the groove on the top surface of the sealing frame is used to facilitate the bottom end of the collection cover to be inserted and fixed. The sealing A on the inner wall of the groove and the sealing B at the bottom of the collection cover are both made of rubber and have the effect of stretching and deformation to squeeze each other to improve the sealing performance. The L-shaped bracket is fixed by the support frame, and the slide rail and hydraulic cylinder are fixed by the L-shaped bracket; The hydraulic cylinder drives the lifting frame to raise or lower the collection hood to open and close it. At the same time, the slide rail on the inner wall of the L-shaped bracket works in conjunction with the lifting brackets on both sides of the collection hood to ensure that the bottom of the collection hood always corresponds to the slot on the top of the sealing frame, making opening and closing convenient. The other end of the collection hose is connected to the gas transmission pipeline to facilitate the transmission of the collected waste gas to the relevant treatment device.

[0007] Specifically, the sealing frame has a sealing element A bonded inside the corresponding slot, the bottom end of the collection cover is fixed inside the slot, and the bottom of the outer periphery of the collection cover has a sealing element B bonded inside. Both sealing elements A and B are made of rubber.

[0008] By adopting the above technical solution, the groove on the top surface of the sealing frame is used to facilitate the bottom end of the collection cover to be inserted and fixed. The sealing element A on the inner wall of the groove and the sealing element B at the bottom of the collection cover are both made of rubber and have the effect of stretching and deformation to squeeze each other to improve the sealing performance.

[0009] Specifically, support frames are provided on the top of both sides of the treatment pool body.

[0010] By adopting the above technical solution, the L-shaped bracket is fixed by using a support frame.

[0011] Specifically, the inner wall of each L-shaped bracket is equipped with a slide rail, and each lifting bracket is slidably connected to the slide rail via a slider on one side.

[0012] By adopting the above technical solution, the slide rail and hydraulic cylinder are fixed by the L-shaped bracket, and the slide rail is used in conjunction with the lifting brackets on both sides of the collection hood to lift and lower smoothly, ensuring that the bottom of the collection hood always corresponds to the slot at the top of the sealing frame.

[0013] Specifically, a lifting frame is installed on the top of the collection hood, and the driving ends of the hydraulic cylinders are all connected to the lifting frame.

[0014] By adopting the above technical solution, a hydraulic cylinder is used to drive the lifting frame to raise or lower the collection cover, thereby achieving the function of opening and closing.

[0015] The beneficial effects of this utility model are: The waste gas collection device for a sewage treatment pond described in this utility model uses a slot on the top surface of the sealing frame to allow the bottom end of the collection cover to be locked in place. The sealing element A on the inner wall of the slot and the sealing element B at the bottom of the collection cover are both made of rubber and have a stretching and deforming effect, which squeezes each other to improve the sealing performance.

[0016] The waste gas collection device for sewage treatment ponds described in this utility model uses a hydraulic cylinder to drive a lifting frame to raise or lower the collection hood, thereby achieving the function of opening and closing. At the same time, the sliding rail on the inner wall of the L-shaped bracket cooperates with the lifting brackets on both sides of the collection hood to smoothly raise and lower, ensuring that the bottom of the collection hood always corresponds to the slot at the top of the sealing frame, making opening and closing convenient.
