Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, and in particular to an interception device for wastewater treatment in a wastewater treatment pond. Background Technology
[0002] Wastewater treatment involves using physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, making full use of water resources. Wastewater treatment screens are water treatment devices that can continuously and automatically intercept and remove various impurities from fluids. They are mainly used in urban sewage treatment, the tap water industry, and power plant inlets, and can also be used as pre-screening devices for industrial wastewater treatment in textiles, food processing, and other industries.

[0016] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0017] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.
[0018] In existing technologies, waste treatment refers to the process of reducing, recycling, and rendering harmless the waste generated during oil and gas drilling and urban infrastructure construction. Treatment of wastewater requires solid-liquid separation followed by flocculation for purification. Flocculation refers to the aggregation and enlargement of suspended particles in water or liquid, forming flocs, thereby accelerating particle settling and achieving solid-liquid separation. This phenomenon or operation is called flocculation. Flocculation is usually achieved by adding appropriate flocculants, which adsorb particles and promote aggregation. Existing technologies often employ passive sedimentation and multi-stage filtration methods. The filter structure is easily clogged by sand and gravel, requiring regular manual unclogging, which is time-consuming, labor-intensive, and delays treatment progress. High viscosity of the waste and larger impurities easily clog the filter screen, leading to low filtration efficiency and reduced equipment lifespan.
[0019] Therefore, the present invention aims at least in the following ways: The interception mechanism 200 drives the filter plate 213 to rise and fall within the filter plate groove 104 to filter impurities, temporarily storing them in the water storage tank 101. When the filter plate 213 filters too much impurity, the air pump in the air box 214 can blow air in the opposite direction onto the filter plate 213, thus blowing off the impurities on the surface of the filter plate 213. Starting the drive motor 208 allows the stirring plate 204 at the lower end of the rotating shaft 202 to collect the blown-off impurities, improving the durability and service life of the filter plate 213. The impurities in the water storage tank 101 are controlled by the rotating shafts 202 on both sides, causing the stirring plate 204 to rotate and move into the impurity pool 109. The reciprocating electric push rod 215 pushes the rectangular bracket 304 to reciprocate along the upper slide rail 106. The lever 310 inside the rectangular bracket 304... It can transport dried debris from one end of the water storage tank 101 through the debris tank 109 to the other end. When debris accumulates on one side of the debris tank 109, it can also drive the L-shaped pressure plate 307 to move into the debris tank 109 and compact the debris into blocks. The transport mechanism 300 includes an upper crossbar 301, an extension rod 302, a transmission connecting rod 303, a rectangular bracket 304 and a lever plate 310 inside it, and an L-shaped pressure plate 307 connected by the mounting bracket 308, all fixed to the mounting plate 205. When the electric push rod 215 reciprocates, it synchronously drives the filter plate 213 to rise and fall for filtration through the linkage mechanism, the rectangular bracket 304 drives the lever plate 310 to reciprocate to transport debris along the upper slide rail 106, and drives the L-shaped pressure plate 307 to swing and compact the debris, so that filtration, transportation and compaction are completed in conjunction with the same electric push rod 215.
[0020] Example, according to Figures 1-8 This invention provides an interception device for wastewater treatment in a wastewater treatment pond, comprising a water storage mechanism 100, an interception mechanism 200 installed within the water storage mechanism 100, and a transport mechanism 300 also installed within the water storage mechanism 100, with the interception mechanism 200 connected to the transport mechanism 300; as... Figure 3As shown, the water storage mechanism 100 includes a water storage tank 101, a debris tank 109 connected to one side of the water storage tank 101, and the water storage tank 101 and the debris tank 109 are internally connected. The water storage tank 101 has an internal slope. A baffle groove 103 is formed on the side of the water storage tank 101 near the debris tank 109. A filter plate groove 104 is formed above the side of the debris tank 109 near the water storage tank 101. A water inlet 102 is formed on one side of the water storage tank 101, and a water outlet 108 is formed at one end of the debris tank 109. The upper surface of the debris tank 109 is close to the water storage tank 101. A top cover plate 105 is fixed to one side, and an upper slide rail 106 is fixed to the middle of the lower surface of the top cover plate 105. Side limiting grooves 107 are provided between the two sides of the top cover plate 105 and the debris pool 109. Flocculant and debris wastewater are poured into the water storage tank 101. The interception mechanism 200 can stir and mix the debris and flocculant to make them fully mixed and accelerate the flocculation reaction of the debris wastewater. At the same time, clean water can be added through the inlet 102 to dilute the debris. The purified water after flocculation is discharged into the water tank through the outlet 108, so that the purified debris is at the bottom of the water storage tank 101.
[0021] like Figures 4-6As shown, the interception mechanism 200 includes a mounting plate 205. A limiting hole 211 is formed through one side of the mounting plate 205. An output shaft of an electric push rod 215 is fixedly connected to one side of the mounting plate 205. The electric push rod 215 is fixedly connected to the upper surface of the upper cover plate 105. Connecting sheet metal 212 is fixedly connected to both sides of the lower surface of the mounting plate 205. A fixing bracket 206 is fixedly connected to the lower end of the connecting sheet metal 212. A filter plate 213 is fixedly connected to the lower surface of the fixing bracket 206. An air box 214 is provided on one side of the filter plate 213. The air box 214 is fixedly connected to... The filter plate 213 is located in the filter plate groove 104 on the lower surface of the fixed bracket 206. The mounting plate 205 is located above the water storage tank 101. A partition 207 is slidably installed in the limiting hole 211. The partition 207 is installed in the partition groove 103 via a lifting mechanism. Two rotating shafts 202 are rotatably installed on the top plate 201. The upper ends of the two rotating shafts 202 are fixedly connected to sprockets 209. The two sprockets 209 are connected together by a chain 210. The lower ends of the two rotating shafts 202 are fixedly connected to a stirring plate 204. Located within the water storage tank 101, a gear 203 is fixedly connected to the upper end of a rotating shaft 202 on one side. The output shaft of a drive motor 208 is also connected to the rotating shaft 202 via the gear 203. The drive motor 208 is fixedly connected to the upper surface of the top plate 201. Starting the lifting mechanism can cause the partition 207 to rise and fall within the partition groove 103. The partition 207 connects and separates the water storage tank 101 and the debris pool 109 to intercept debris. Furthermore, the start / stop electric push rod 215 drives the filter plate 213 to rise and fall within the filter plate groove 104 to further filter debris. The filter plate 213 filters out too much debris and temporarily stores it in the water storage tank 101. When the filter plate 213 filters out too much debris, the air pump in the air box 214 can blow air back onto the filter plate 213 to blow off the debris from the surface of the filter plate 213. At the same time, the drive motor 208 is started and drives the two rotating shafts 202 to rotate through the gear 203, sprocket 209 and chain 210. The stirring plate 204 at the lower end of the rotating shaft 202 can collect the debris in the water storage tank 101 to one side of the debris pool 109, gather the debris and intercept it through the filter plate 213 for efficient interception.
[0022] like Figures 7-8As shown, the transport mechanism 300 includes two upper crossbars 301, which are fixed to both ends of the outer wall of the mounting plate 205. Extension rods 302 are fixed to the lower surface of each upper crossbar 301. A transmission connecting rod 303 is rotatably mounted to the lower end of each extension rod 302. A rectangular bracket 304 is rotatably mounted to the lower end of the transmission connecting rod 303. A lower sliding plate 305 is fixed to the lower surface of the rectangular bracket 304 and fits tightly against the inner wall of the debris pool 109. An installation groove 311 is formed in the middle of the rectangular bracket 304. Two levers 310 are rotatably mounted on both sides of the installation groove 311. The upper end of the rectangular bracket 304 is slidably mounted on an upper slide rail 106. An L-shaped bracket 306 is fixed to one end of each upper crossbar 301. An installation bracket 308 is rotatably mounted to the lower end of the L-shaped bracket 306 and one end of the installation bracket 308 is rotatably mounted on the mounting plate. On one side of 205, a connecting plate 309 is rotatably mounted on the upper end of the mounting bracket 308. An L-shaped pressure plate 307 is fixedly connected to one side of the connecting plate 309. The L-shaped pressure plate 307 is located inside the debris pool 109. When the electric push rod 215 is reciprocated, it will also push the upper crossbar 301 and the L-shaped bracket 306 to rise and fall. The rectangular bracket 304 is pushed to reciprocate along the upper slide rail 106 through the extension rod 302 on the lower surface of the upper crossbar 301 and the transmission connecting rod 303. The lever 310 inside the rectangular bracket 304 can realize the conveying of dried debris from one end of the water storage tank 101 through the debris pool 109 to the other end. When the debris accumulates on one side of the debris pool 109 and the upper crossbar 301 moves downward, it will drive the mounting bracket 308 to rotate on one side of the mounting plate 105, which will drive the L-shaped pressure plate 307 to move into the debris pool 109 and compact the debris into blocks.
[0023] The working principle of this invention is as follows: Starting the elevator causes the partition 207 to rise and fall within the partition groove 103. The partition 207 connects and separates the water storage tank 101 and the debris tank 109 to intercept debris. Then, the start / stop electric push rod 215 causes the filter plate 213 to rise and fall within the filter plate groove 104 to filter the debris, temporarily storing it in the water storage tank 101. When the filter plate 213 filters too much debris, the air pump in the air box 214 blows air in the opposite direction onto the filter plate 213, blowing the debris off its surface. Simultaneously, the drive motor 208, through the gear 203, sprocket 209, and chain 210, drives two rotating shafts 202 to rotate. The agitator plate 204 at the lower end of the rotating shafts 202 can collect the debris from the water storage tank 101. The debris is gathered and efficiently intercepted by the filter plate 213 on one side of the debris pool 109. The reciprocating electric push rod 215 also pushes the upper crossbar 301 and L-shaped bracket 306 to rise and fall. The rectangular bracket 304 is pushed to move back and forth along the upper slide rail 106 through the extension rod 302 on the lower surface of the upper crossbar 301 and the transmission connecting rod 303. The deflector plate 310 in the rectangular bracket 304 can realize the transportation of the dried debris from one end of the water storage tank 101 through the debris pool 109 to the other end. When the debris accumulates on one side of the debris pool 109 and the upper crossbar 301 moves downward, it will drive the mounting bracket 308 to rotate on one side of the mounting plate 105, which will drive the L-shaped pressure plate 307 to move into the debris pool 109 and compact the debris into blocks.
