Description

Technical Field

[0001] This utility model relates to the technical field of curtain equipment, specifically an electric curtain for a water plant filtration pool. Background Technology

[0002] A filtration tank is a water treatment structure that removes suspended insoluble substances from raw water or wastewater by passing it through a filter medium. It is commonly divided into two types: gravity filtration tanks with top-down flow and pressure filtration tanks with bottom-up flow. The working cycle generally includes two processes: filtration and backwashing. Filtration tanks are often used in the treatment of water supply and wastewater after sedimentation, and are also used for advanced water treatment. Water plant filtration tanks usually need to be used in conjunction with curtains. Electric curtains can effectively prevent dust, leaves, insects and other debris in the air from entering the filtration tank and protect the filtration equipment.

[0003] Most water plant filtration tanks currently do not have curtains installed, and in water plants where curtains are installed, the curtains are mostly manually operated, which is inconvenient for people to operate. Therefore, those skilled in the art provide an electric curtain for water plant filtration tanks to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an electric curtain for a water plant filtration tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An electric curtain for a water plant filtration tank includes a curtain retraction roller positioning assembly and a drive assembly. The curtain retraction roller positioning assembly includes a crossbeam. Two sets of mounting plates are installed on the outer surface of the crossbeam. Each mounting plate has a mounting hole on its outer surface, and a mounting screw is installed inside each mounting hole. A sliding groove is formed on the outer surface of the crossbeam. Two sliding blocks are slidably connected inside the sliding groove. A connecting rod is installed on the outer surface of each of the two sliding blocks. A symmetrical first bearing is embedded in the inner wall of the crossbeam. A bidirectional lead screw is installed on the inner ring of the two first bearings. Both sliding blocks are threadedly connected to the bidirectional lead screw. A first servo motor is installed on the outer surface of the crossbeam, and the output end of the first servo motor is connected to the bidirectional lead screw.

[0007] As a further improvement of this utility model: the driving assembly includes two fixing plates, and the outer surfaces of both fixing plates are connected to the connecting rod.

[0008] As a further improvement of this utility model: the outer surfaces of both fixing plates are inlaid with second bearings, and the inner rings of both second bearings are fitted with limit tubes.

[0009] As a further embodiment of this utility model: both of the limiting tubes are fitted with locking blocks inside, and the outer surfaces of the two locking blocks are jointly equipped with curtain winding rollers. The outer surfaces of the curtain winding rollers are equipped with two baffles, and the outer surfaces of the curtain winding rollers are wrapped with filter curtains.

[0010] As a further embodiment of this utility model: a second servo motor is mounted on the outer surface of one of the fixed plates, and the output end of the second servo motor is connected to one of the limiting tubes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The water plant's filtration tank uses an electric curtain. Through the cooperation of a crossbeam, sliding groove, sliding block, first bearing, first rotating rod, first servo motor, connecting rod, second servo motor, curtain winding and unwinding roller, second servo motor, fixing plate, second bearing, limit tube, and locking block, the equipment can not only disassemble and assemble the curtain winding and unwinding roller, but also wind and unwind the filter curtain, thus facilitating operation. The baffle design makes the winding and unwinding of the filter curtain by the curtain winding and unwinding roller smoother. Attached Figure Description

A second servo motor 208 is installed on the outer surface of one of the fixed plates 201. The output end of the second servo motor 208 is connected to one of the limit tubes 203. This allows people to disassemble and assemble the filter curtain 207, making it convenient for cleaning or replacement. It also enables the equipment to automatically wind and unwind the filter curtain 207, making it easy for people to operate.

[0023] The working principle of this utility model is as follows: First, people can place the equipment in the usage position and connect the power supply. Then, the locking block 204 can be aligned with the limiting tube 203 and the first servo motor 106 can be started. The first servo motor 106 can drive the bidirectional lead screw 105 to rotate. The bidirectional lead screw 105 can drive the sliding block 103 and the connecting rod 107 to move. After the locking block 204 completes the engagement with the limiting tube 203, the first servo motor 106 is turned off. The second servo motor 208 can drive the curtain winding and unwinding roller 205 to rotate and wind up and unwind the filter curtain 207.
