Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a water treatment reaction pool system. Background Art

[0002] Water treatment reaction tank is a common part of the water treatment process. It is widely used in industrial and domestic sewage treatment, environmental protection and sewage treatment, etc., effectively improving water quality and reducing pollutant emissions. It includes anaerobic tank, anoxic tank and aerobic tank. The three tanks work together to remove organic matter in wastewater through the action of different bacteria and chemical processes, thereby achieving the purpose of treating water quality.

[0003] In an anaerobic tank, due to the anaerobic conditions in the tank, bacteria will decompose organic matter to produce compounds such as sulfide, sulfate and ammonia, thereby producing a foul odor. Although the anaerobic tank is currently connected to a deodorization device to control the spread of the odor, the anaerobic tank is usually open-air, and some odor will still leak out, affecting the air environment. In addition, there is suspended matter settling in the anaerobic tank, specifically solid particulate matter in the wastewater, bacterial communities, and sulfide precipitation. The accumulation of these sediments will cause the normal operation of the anaerobic tank, but due to the presence of a stirring shaft and a flow promoter in the anaerobic tank, it is more troublesome to clean up the sediment. Utility Model Content

[0004] The utility model aims to provide a water treatment reaction tank system which can prevent odor leakage and facilitate the cleaning of anaerobic tank sediments.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A water treatment reaction tank system comprises an anaerobic tank, an anoxic tank and an aerobic tank. The anaerobic tank is connected with the anoxic tank, and the anoxic tank is connected with the aerobic tank through a connecting slot.

[0007] A mounting plate is connected between the inner walls on both sides of the anaerobic tank, vertical poles are installed on both sides of the bottom of the mounting plate, flow promoters are installed on the outer surfaces of the vertical poles, a stirring shaft is installed at the bottom of the mounting plate between the two vertical poles, there are gaps between the vertical poles and the stirring shaft and the bottom of the anaerobic tank, a scraper is arranged inside the anaerobic tank, and the height of the scraper is within the gap.

[0008] Both ends of the upper side of the scraper are connected with connecting rods, and a driving mechanism capable of driving the connecting rods to move horizontally is arranged inside the anaerobic tank.

[0009] A groove is provided inside the anaerobic tank, a sewage pipe is installed on the inner wall of the groove, and the sewage pipe extends to the outside of the anaerobic tank, and a sewage pump is arranged on the sewage pipe.

[0010] An exhaust pipe is installed on the inner wall of one side of the anaerobic tank, and the end of the exhaust pipe extends to the outside of the anaerobic tank and is connected to the deodorization device. A cover plate is installed on the upper side of the anaerobic tank through a lifting mechanism, and the lifting mechanism can drive the cover plate to rise and fall.

[0011] It can be seen that by installing the vertical rod and the stirring shaft on the mounting plate, a certain gap is left between the bottom of the vertical rod and the bottom wall of the anaerobic tank, thereby providing a space for the scraper to move. The scraper is driven to move by the driving mechanism, so that the sediment accumulated at the bottom of the anaerobic tank can be scraped off and concentrated in the groove, and finally it can be pumped away by the sewage pump, thereby achieving the purpose of facilitating the cleaning of the sediment in the anaerobic tank. By covering the anaerobic tank with a cover plate, the interior of the anaerobic tank is made into a closed space, thereby preventing odor from leaking and avoiding affecting the on-site air environment. The cover plate can be raised and lowered by the lifting mechanism, thereby not affecting the operation and maintenance of the staff.

[0012] Furthermore, the driving mechanism includes two threaded rods rotatably connected inside the anaerobic tank, and the ends of the two threaded rods extend to the outside of the anaerobic tank, the outer surfaces of the threaded rods are installed with nut seats, the tops of the connecting rods are connected to the nut seats, and the outer surfaces of the ends of the two threaded rods are provided with pulley sets for transmission, and a motor is installed outside the anaerobic tank, and the output shaft of the motor is connected to one of the threaded rods.

[0013] When the motor is started, a threaded rod connected to it is driven to rotate, and through the transmission action of the pulley group, the two threaded rods can be rotated at the same time, and the nut seats thereon are driven to move respectively. The connection action of the connecting rod can drive the scraper to move, and the sediment at the bottom of the anaerobic tank is scraped into the groove for aggregation. Finally, the sewage pump can be started to discharge the sediment from the sewage pipe to ensure the normal operation of the anaerobic tank.

[0014] Furthermore, the lifting mechanism includes four installation grooves opened at the four corners of the upper side of the anaerobic tank, and a hydraulic cylinder is installed inside the installation groove, and the end of the hydraulic cylinder is connected to the bottom of the cover plate.

[0015] During normal use, the hydraulic cylinder can be started to drive the cover down so that the cover is covered on the upper side of the anaerobic tank, thereby preventing the spread of odor and allowing the odor inside the anaerobic tank to enter the deodorization device through the exhaust pipe for filtration and purification, thus ensuring the on-site air environment. In addition, since the cover can be raised and lowered by the hydraulic cylinder, it will not affect the operation and maintenance of the staff.

[0016] Furthermore, a sealing gasket is provided on the lower surface of the cover plate, and a plurality of notches are provided on the sealing gasket.

[0017] The provision of the sealing gasket can not only improve the sealing effect, but also play a role in buffering and shock absorption, thereby preventing the cover plate from being damaged by hard contact with the anaerobic tank. The gap can ensure air circulation inside the anaerobic tank, allowing external air to enter the anaerobic tank, while the odor inside the anaerobic tank enters the deodorization device through the exhaust pipe.

[0018] Furthermore, an observation window is provided on the cover plate.

[0019] The setting of the observation window can facilitate the operator to observe the operation status inside the anaerobic tank.

[0020] Furthermore, slide grooves are provided on the inner walls of both sides of the anaerobic tank, and sliding blocks are provided inside the slide grooves, and the ends of the sliding blocks are connected to the nut seats.

[0021] The stability of the scraper when moving can be improved by setting the slide groove and the slider. BRIEF DESCRIPTION OF THE DRAWINGS

Through the connection action of the connecting rod 110, the scraper 109 can be driven to move, and the sediment at the bottom of the anaerobic tank 100 can be scraped into the groove 111 for aggregation. Finally, the sewage pump 113 can be started to discharge the sediment from the sewage pipe 112 to ensure the normal operation of the anaerobic tank 100.
