Description

Technical Field

[0001] The utility model is a rotating disk for water treatment, belonging to the technical field of water treatment. Background Art

[0002] The biological turntable is a biofilm wastewater treatment equipment. The conventional biological turntable is composed of many circular or polygonal discs with small spacing fixed on a rotating shaft. The discs are made of materials such as polyvinyl chloride, polyethylene, foam polystyrene, fiberglass, and aluminum alloy. The two ends of the rotating shaft need to be rotatably connected to its supporting carrier using bearings, and one end of the rotating shaft also needs to be connected to the output end of the motor. When the motor is working, it drives the structure formed by the rotating shaft and the turntable to rotate in the sewage tank. At this time, the sewage mixed with impurities attached to the turntable is easy to diffuse along the surface of the rotating shaft to the connection between the rotating shaft and the bearing, resulting in increased resistance in the bearing due to the attachment of more impurities, which requires irregular maintenance. Therefore, it is necessary to design a water treatment turntable that prevents sewage mixed with impurities from diffusing to the connection between the rotating shaft and the bearing. Utility Model Content

[0005] Furthermore, the limiting member includes a screw, and a side surface of the baffle is threadedly connected with a screw for limiting the relative position of the turntable and the rotating shaft. The screw is arranged parallel to the rotating shaft, and a bull's eye is installed at one end of the screw close to the turntable. The ball portion in the bull's eye is in rolling contact with the turntable, and a handle is installed at the end of the screw away from the bull's eye.

[0006] Furthermore, a circular hole is opened at the edge of one side of the baffle plate, a straight cylinder is installed in the circular hole, a positioning plate is connected and fixed in the middle position of the straight cylinder, a screw hole is opened in the middle position of one side of the positioning plate, the screw is threadedly connected in the screw hole, and spacer rings are provided on both sides of the positioning plate along the length direction of the screw, the spacer rings are sleeved on the screw and connected and fixed to the screw, and the spacer rings are slidably installed in the straight cylinder.

[0007] Furthermore, two fixing holes for inserting bolts are provided on a side of the support plate away from the tube, and the support plate is arranged along the radial direction of the tube.

[0008] Furthermore, the inner surface of the turntable is recessed to form a keyway, and the outer surface of the shaft is connected and fixed with a key bar arranged along the length direction of the shaft, and the key bar is inserted in the keyway.

[0009] Furthermore, bearings are sleeved on both ends of the rotating shaft, the two tubes are arranged between the two rotating shafts, and one end of the rotating shaft is connected and fixed with a flange.

[0010] Beneficial effects of the utility model:

[0011] 1. When the motor drives the shaft to rotate, the shaft drives the two spiral blades to rotate in the two tubes respectively, and the rotation direction of the two spiral blades is toward the middle of the shaft, and then the sewage mixed with impurities in the tube will move toward the turntable under the push of the spiral blades, preventing the sewage mixed with impurities from spreading to the connection between the shaft and the bearing, eliminating the need for irregular maintenance and cleaning of the bearings, and reducing management costs.

[0012] 2. After the position of the tube is restricted, use the handle to rotate the screw rod to make the ball part of the bull's eye roll in contact with the turntable, and then under the limitation of the two sets of screw rods and the bull's eye rod, the relative positions of the multiple turntables and the rotating shaft remain unchanged.

[0013] 3. When the screw is rotated, the screw drives the two spacer rings to move in the straight tube, and the spacer rings do not move to the outside of the straight tube. Then the two spacer rings and the straight tube cooperate with each other to keep the connection between the screw and the screw hole in a closed environment, preventing debris from entering the connection between the screw and the screw hole and affecting the rotation of the screw.
