Description
Technical Field
[0001] The utility model belongs to the technical field of water treatment in water delivery channels, and in particular relates to algae intercepting equipment at a water inlet of a forebay of a pump station. Background Art
[0002] When large pumping stations are pumping water, the water flow rate is very high. Especially during the flood season or peak water supply period, the water diversion channel will encounter a large number of floating objects such as algae, dead branches and leaves. If the algae are not cleaned up in time, the pump station will run at no load, threatening the safety of the pump station. Therefore, in order to prevent algae and other floating objects from entering the pump station and affecting the operation of the pump station, it is urgent to install algae interception equipment at the water inlet of the pump station forebay. Utility Model Content
[0003] The utility model aims to provide an algae intercepting device at the water inlet of a pump station forebay, which has a simple structure, is easy to install, has a low cost, has a high algae intercepting efficiency, and can completely replace the existing high-cost sewage cleaning machines and manual cleaning.
[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: an algae blocking device at the water inlet of the forebay of a pumping station, comprising a support frame arranged at the rear side of the water inlet of the forebay of the pumping station, the support frame being provided with a rotating drive mechanism and a circulating lifting chain transmission mechanism with a transmission connection, the circulating lifting chain transmission mechanism being covered with an algae blocking mesh, the front part of the support frame being fixed with water filter plates on the left and right sides of the water inlet of the forebay of the pumping station, the algae blocking mesh being located between the rear sides of the two water filter plates, the left and right sides of the algae blocking mesh having a gap of 1-5mm with the water filter plates on the left and right sides, a frame platform being horizontally provided on the upper part of the support frame, a high-pressure jet water spraying device being provided on the front side of the frame platform for spraying toward the algae blocking mesh, an algae-water separation device being provided below the position where the high-pressure jet water spraying device sprays onto the algae blocking mesh.
[0005] The circulating lifting chain transmission mechanism includes a driving sprocket shaft, a driven sprocket shaft, a first reversing sprocket shaft and a second reversing sprocket shaft, which are all rotatably arranged on the supporting frame and are horizontally arranged in the left and right directions. The rotating driving mechanism is a motor reducer, the motor reducer is installed on the top of the supporting frame, the driving sprocket shaft is located below the motor reducer, the driven sprocket shaft is arranged at the bottom of the supporting frame, the first reversing sprocket shaft is arranged below the front side of the driving sprocket shaft, and the second reversing sprocket shaft is arranged below the rear side of the first reversing sprocket shaft. The motor reducer is connected to one end of the driving sprocket shaft through a driving chain, and the two ends of the driving sprocket shaft, the driven sprocket shaft, the first reversing sprocket shaft and the second reversing sprocket shaft are respectively connected through an annular chain. The left and right sides of the algae blocking net are respectively installed on the annular chains on the left and right sides, and a number of horizontal support rods for supporting the algae blocking net are passed between the annular chain on the left and the annular chain on the right.
[0006] The high-pressure jet water spraying device includes a spray pipe arranged in the left-right direction. The spray pipe is located below the algae-blocking net sheet between the driving sprocket shaft and the first reversing sprocket shaft and above the algae-blocking net sheet between the first reversing sprocket shaft and the second reversing sprocket shaft. A number of nozzles spraying forward and downward are installed on the spray pipe. One end of the spray pipe is blocked, and the other end of the spray pipe is connected with a water suction pipe. The water suction pipe extends vertically along the support frame to below the water surface and is connected with a submersible pump.
[0007] The algae-water separation device includes a water filtration frame and a water guiding frame arranged below the water filtration frame. The water filtration frame is inclined with the front end lower and the rear end higher. The water guiding frame is inclined with the front end higher and the rear end lower. A water filtration net is laid on the water filtration frame. First baffles are arranged on the left side, right side and rear side of the water filtration frame. A material guiding plate connected with the water filtration net is arranged on the front side of the water filtration frame. A water guiding plate is laid on the water guiding frame. Second baffles are arranged on the left side, right side and front side of the water guiding frame. The rear side edge of the water guiding plate extends above the frame platform. A rectangular water dropping hole located below the rear side edge of the water guiding plate is opened on the frame platform.
[0008] The front side of the support frame is fixedly connected to the rear side wall of the front pool of the pumping station through the first expansion bolts. Railings are arranged on the left side, right side and rear side of the frame platform. A horizontal anchoring plate is fixedly arranged on the front side of the frame platform. The horizontal anchoring plate extends forward to the top surface of the pool wall of the front pool of the pumping station. The horizontal anchoring plate is fixedly connected to the top surface of the front pool of the pumping station through the second expansion bolts.
[0009] Adopting the above technical solution, the working principle and process of the utility model are as follows: Water flows from front to back through the water inlet of the front pool of the pumping station into the space between the algae-blocking net sheet and the two water filtering net plates. The two filtering net plates are fixed. The electric speed reducer drives the driving sprocket shaft to rotate through the driving chain. The driving sprocket shaft drives the entire algae-blocking net sheet to circulate through the two annular chains. Algae in the water continuously adhere to the front surface of the algae-blocking net sheet under the action of the water flow. The algae-blocking net sheet with attached algae moves upward. The submersible pump pumps out clear water from the front pool of the pumping station and sprays high-pressure jet water through a number of nozzles on the spray pipe. The algae attached to the surface of the algae-blocking net sheet run to the high-pressure jet of the nozzle and are washed off by the water flow and fall onto the water filtration net. The algae slide forward along the surface of the water filtration net with the rear end higher and the front end lower. The water falls from the water filtration net onto the water guiding plate, thus separating the algae and the water. Finally, the algae fall into the collection box placed on the top surface of the front pool of the pumping station through the material guiding plate. The water falls along the rear side edge of the water guiding plate and falls into the front pool of the pumping station through the rectangular water dropping hole on the frame platform. According to the above algae-blocking and algae-water separation method, the submersible pump and the motor speed reducer keep working, and the algae-blocking and algae-removing operation of the water entering the front pool of the pumping station can be realized.
[0010] Due to the limited width (front - to - back direction) at the top of the pool wall of the pump station forebay, the support frame is set to be relatively long in the front - to - back direction to increase the area of the frame platform. At the same time, the lower part of the algae - intercepting mesh sheet is set at a certain distance from the water inlet of the pump station forebay, and water - passing filter plates are arranged on the left and right to play the role of passing water and intercepting algae.
[0011] The algae - intercepting mesh sheet is made of stainless - steel wire woven mesh. Compared with the fiber - rope mesh, the stainless - steel woven mesh can be soaked in water for a long time without easy aging. In addition, it also has the characteristics of corrosion resistance, good toughness, good ventilation, and easy cleaning, and can meet the requirements of intercepting algae. After algae and other floating objects adhere to the rotary net, the high - pressure jet water - spraying device is the device for removing algae from the rotary net, and it is an important link to ensure the continuous operation of algae interception.
[0012] Due to seasonal changes, the types and quantities of algae in the channels at different times are different. To adapt to this situation, the running speed of the algae - intercepting mesh sheet is adjustable. When there is more algae, the cycle of the algae - intercepting mesh sheet speeds up, and the algae are fished out of the channel faster, so that the rotary net will not be blocked. When there is less algae, the cycle of the algae - intercepting mesh sheet slows down, which can delay the wear of mechanical equipment parts and extend the service life of the equipment.
[0013] The working condition of the support frame is that the lower part is soaked in water for a long time. The support frame should be made of corrosion - resistant materials. Secondly, the design of the support frame should also meet the requirements of stiffness, strength, and stability. In the present utility model, the overall structure of the support frame is made of a truss structure welded by 100×100mm and 80×80mm stainless - steel hollow square tubes. A frame platform is welded at the top of the support frame for daily equipment operation and maintenance, and railings are welded around the frame platform to ensure walking safety. Connecting frames are welded in the middle of the left and right sides of the support frame, and the stability and safety of the support frame in the pump station forebay are ensured by installing the first expansion bolts.
[0014] Stainless - steel material has good corrosion resistance. Making the frame with square tubes has good processing performance. The two ends of the square tubes are easier to be welded to form a closed space, ensuring that the inside of the square tube is hollow. When the support frame enters the water, the buoyancy provided by the support frame itself can effectively reduce the pressure of the self - weight of the support frame on the bottom of the pump station forebay.
[0015] In summary, the present utility model drives the cyclic movement of the algae - intercepting mesh sheet, lifts the algae attached to the algae - intercepting mesh sheet above the water surface, and separates the algae from the algae - intercepting mesh sheet by means of high - pressure water spraying. It is easy to implement, clean and environmentally friendly, convenient for obtaining materials, has high efficiency, low failure rate, stable performance, and safe and reliable operation, providing guarantee for the environmental maintenance of long - distance water - conveyance projects and ensuring the water supply safety of long - distance water - conveyance projects.
