Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices, in particular to a waste gas collecting device used in a small sewage treatment pool. Background Art

[0002] Wastewater treatment is an indispensable part of urban and industrial development. Its main goal is to convert wastewater into harmless or reusable water sources. However, various waste gases, including toxic gases and odorous gases, are generated during the sewage treatment process. If these waste gases are not controlled and treated, they may have adverse effects on the environment and human health. Therefore, in the sewage treatment system, the collection and treatment of waste gases become necessary steps.

[0003] Traditional exhaust gas collection devices usually use a whole sealing cover plate to cover the sewage pool, and exhaust the exhaust gas through a vacuum device. However, this traditional design has some obvious defects. When the sewage pool needs to be inspected, maintained, or cleaned of precipitated impurities, the whole sealing cover plate must be lifted by a crane, which is time-consuming, labor-intensive and costly. Utility Model Content

[0004] The utility model provides a waste gas collection device for a small sewage treatment pool, aiming to solve the defect that a crane is required to lift the entire cover plate of a traditional device during inspection, maintenance or cleaning.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a waste gas collection device for a small sewage treatment pool, including a sewage pool, the upper end of the sewage pool is open and a sealing cover plate is provided at the open part, an air pump is provided at one corner of the upper end of the sealing cover plate, and an air inlet is provided at the other corner of the upper end of the sealing cover plate opposite to the air pump, the sealing cover plate includes a fixed cover plate and a sliding cover plate, the fixed cover plate is fixed on one side of the upper end of the sewage pool, and the sliding cover plate slides on the other side of the upper end of the sewage pool, the fixed cover plate and the sliding cover plate are butt-jointed and sealed, and power units for driving the sliding cover plates to slide are fixed on both sides of the sewage pool.

[0006] Furthermore, a slide groove is provided at the upper end of the sewage pool, and a sliding block is fixedly provided at the bottom of the sliding cover plate, and the sliding block is matched with the slide groove and slidably connected.

[0007] Furthermore, a sealing strip is fixedly provided on the inner side wall of the slide groove.

[0008] Furthermore, the air pump is fixed on the fixed cover plate, and the air inlet is fixed on the sliding cover plate.

[0009] Furthermore, a check valve is provided inside the air inlet.

[0010] Furthermore, the power unit adopts an electric push rod, one end of which is fixedly connected to the sewage tank, and the piston end of which is fixedly connected to the sliding cover plate.

[0011] Furthermore, a lower extension plate is fixedly provided on the outer side of the sliding cover plate, and a second sealing strip is fixedly provided on the inner side of the lower extension plate.

[0012] Compared with the prior art, the utility model has the following advantages: the design of the device combines a fixed cover plate and a sliding cover plate, so that the cover plate can be partially opened, which simplifies the operation process and reduces the maintenance cost. The setting of the sliding cover plate makes it unnecessary to lift the entire cover plate when the sewage pool needs to be repaired or cleaned. Only the sliding cover plate is needed to open part of the area, which greatly reduces the operation time and labor cost. At the same time, the sliding cover plate is sealed and connected to the fixed cover plate by sealing strips and sliding grooves, ensuring that the exhaust gas will not leak during normal operation, thus ensuring the safety of the environment. In addition, the positions of the vacuum pump and the air inlet in the device are reasonably distributed, ensuring the efficient collection of the exhaust gas. The vacuum pump is fixed on the fixed cover plate, and the air inlet is fixed on the sliding cover plate. A check valve is also provided inside to avoid the backflow of the exhaust gas. This design further improves the safety and practicality of the device, and is suitable for the exhaust gas collection needs of small sewage treatment pools. BRIEF DESCRIPTION OF THE DRAWINGS
