Description

Technical Field

[0001] This utility model relates to the technical field of sedimentation and purification water storage tank structure, and in particular to a high-efficiency sedimentation and purification water storage tank for water conservancy projects. Background Technology

[0002] A reservoir is a facility used to store water resources and is widely used in agricultural irrigation, industrial water use, urban water supply, and flood control and drought relief. Among them, sedimentation and purification reservoirs are important facilities for water treatment. They are mainly used to remove suspended solids, silt and other impurities from the water to improve water quality. By utilizing the principle of gravity sedimentation, suspended solids and silt in the water naturally settle to the bottom of the reservoir, thereby purifying the water.

[0003] Sedimentation and purification water storage tanks typically include an inlet channel, a sedimentation zone, a sludge hopper, a sludge discharge channel, and a clear water channel. In existing technologies, the mixed liquor enters the sedimentation zone through the inlet channel. After sludge-water separation, the sludge settles into the sludge hopper, while the supernatant is discharged through the clear water channel. This type of water storage tank has several problems: First, although the sludge can be discharged through the sludge hopper at the bottom of the tank, there is no automatic cleaning structure. The deposits and residual sludge on the inner wall of the sedimentation and purification water storage tank will affect the efficient sedimentation and purification of the water storage tank. Second, the sludge hopper is located at the bottom of the tank, and the inlet and outlet are located above it. When water is flowing in and out, the sludge in the sludge hopper is easy to float up. Moreover, not every treatment zone is equipped with a sludge hopper, which is not conducive to subsequent cleaning. Utility Model Content

[0004] The main purpose of this invention is to provide a high-efficiency sedimentation and purification water storage tank for water conservancy projects, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-5 As shown, a high-efficiency sedimentation and purification water storage tank for water conservancy projects includes a sedimentation water storage tank 1. A movable scraper 2 is fixedly installed at the upper end of the sedimentation water storage tank 1. The sedimentation water storage tank 1 includes a water storage tank body 101, an inlet valve 102, an outlet valve 103, a first sludge hopper 104, a second sludge hopper 105, a third sludge hopper 106, a sludge valve 107, an inlet baffle 108, and a clear water baffle 109. The movable scraper 2 includes a scraper blade 201, a limiting slide bar 202, a motor outer frame 203, a limiting frame 204, a bidirectional motor 205, and a screw 206. The sedimentation tank 1, in conjunction with the movable scraper 2, enables the sedimentation and purification tank to automatically clean the sludge and attached materials inside, which is beneficial for the regular cleaning of the sedimentation and purification tank and ensures the efficient sedimentation and purification of the tank. The sedimentation tank 1 is responsible for sedimenting and purifying the mixed liquor. The inlet and outlet water interfaces and the sludge hopper are located at its two ends, respectively. Each treatment area is equipped with a sludge hopper, which is beneficial for subsequent cleaning and reduces the probability of sludge and attached materials floating in the sludge hopper when draining and filling water. The movable scraper 2 is responsible for scraping the sludge and attached materials off the inner wall of the sedimentation tank 1 and scraping them towards the sludge hopper of the sedimentation tank 1.

[0022] In this embodiment, the inlet valve 102 is fixedly connected to the inlet port of the water storage tank body 101, and the outlet valve 103 is fixedly connected to the outlet port of the water storage tank body 101.

[0023] In this embodiment, sludge hopper 104 is embedded and fixedly installed at one corner of the lower surface of the main body 101 of the water storage tank. Sludge hopper 105 is embedded and fixedly installed at the other corner of the lower surface of the main body 101 of the water storage tank. Sludge hopper 106 is embedded and fixedly installed between sludge hopper 104 and sludge hopper 105 on the lower surface of the main body 101 of the water storage tank. There are three sludge valves 107, which are fixedly installed at the lower ends of sludge hopper 104, sludge hopper 105 and sludge hopper 106 respectively.

[0024] In this embodiment, the inlet baffle 108 and the clear water baffle 109 are both fixedly installed inside the main body 101 of the water storage tank. The inlet baffle 108 is located between the second sludge hopper 105 and the third sludge hopper 106, and the clear water baffle 109 is located between the third sludge hopper 106 and the first sludge hopper 104. During sedimentation and water storage, the inlet valve 102 is opened to drain water into the main body 101 of the water storage tank. The inlet baffle 108 and the clear water baffle 109 divide the interior of the main body 101 of the water storage tank into an inlet area, a sedimentation area and a clear water area. The opening at the rear end of the inlet baffle 108 allows the inlet area and the sedimentation area to be connected. The inlet baffle 108 acts as a barrier, making the water flow in the sedimentation area more stable and suitable for sedimentation. The upper layer of the sedimentation area is clear water. The clear water enters the clear water area through the notch at one corner of the upper end of the clear water baffle 109, and then the outlet valve 103 is opened to discharge it. Alternatively, the outlet valve 103 can be opened to discharge the clear water when the clear water area is full.

[0025] In this embodiment, the sludge scraper 201 is inserted into the interior of the water storage tank body 101. There are three limiting slide rods 202, all of which are located in the through holes of the sludge scraper 201. The two ends of the limiting slide rods 202 are fixedly connected to the interior of the water storage tank body 101.

[0026] In this embodiment, the motor outer frame 203 is fixedly installed on the upper part of the front surface of the water storage tank body 101, and the limiting frame 204 is fixedly installed on the upper part of the rear surface of the water storage tank body 101.

[0027] In this embodiment, the bidirectional motor 205 is fixedly installed inside the motor frame 203. The rear end of the screw 206 is fixedly connected to the rotating shaft of the bidirectional motor 205. The front end of the screw 206 passes through the threaded through hole at the upper end of the scraper 201. The front end of the screw 206 is engaged in the limiting through hole of the limiting frame 204. When cleaning the sedimentation tank 1, the inlet valve 102 and the outlet valve 103 are closed, and the sludge valve 107 is opened. The sewage is discharged slowly first. The bidirectional motor inside the motor frame 203... The machine 205 drives the screw 206 to rotate, which in turn drives the scraper 201 to move along the limiting slide bar 202. The front end of the screw 206 rotates within the limiting frame 204. The scraper 201 scrapes off the sludge and attachments from the inner wall of the main body 101 of the water storage tank, the surface of the inlet baffle 108 and the clear water baffle 109, and pushes them into the interior of the No. 1 sludge hopper 104, the No. 2 sludge hopper 105 and the No. 3 sludge hopper 106. The remaining sewage, sludge and attachments are discharged from the sludge valve 107.

[0028] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
