Description

Technical Field

[0001] The utility model relates to the field of air flotation tank equipment, in particular to a liquid level adjustment device. Background Art

[0002] A flotation tank refers to a tank that mainly uses a large number of microbubbles to capture and adsorb fine particles and adhesives to make them float, thereby achieving the effect of solid-liquid separation. The liquid level regulating device installed in the existing flotation tank includes an outlet pipe, an iron sheet and a clamp. The pipe wall of the outlet pipe is provided with an outlet hole extending along the axial direction. The iron sheet wraps part of the outlet hole and is tightly connected to the outlet pipe through a clamp. The water level is adjusted by the height of the exposed part of the outlet hole. The diameter of the outlet hole of the existing regulating device is fixed, which cannot meet the requirements of high-efficiency drainage.

[0003] According to a patent document with an existing publication number of CN218003988U, a liquid level regulating device for a flotation tank is disclosed, which includes two supporting channel steels and a connecting pipe and a water outlet pipe of the flotation tank. The upper ends of the two supporting channel steels are fixedly connected to a connecting channel steel. The upper end surface of the connecting channel steel is fixedly connected to a mounting seat. A handwheel is rotatably provided on the upper end surface of the mounting seat. A threaded screw is connected to the interior of the handwheel through a threaded sleeve. The lower end of the threaded screw penetrates the connecting channel steel and is fixedly connected to a connecting plate. When in use, this technical solution adjusts the extension length of the threaded screw by rotating the handwheel. Due to the provision of a retractable rubber bellows, the height of the connecting flange can be adjusted, thereby controlling the outflow of liquid in the flotation tank. With respect to the above technical solution, although this solution adjusts the outflow of liquid, the diameter of the water outlet is fixed during use, and the water output cannot meet the use in different situations, which is inconvenient during use.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

A movable rod 23 is installed on the lifting mechanism 8, and one end of the movable rod 23 is fixed on the movable seat 24. The lifting mechanism 8 is an electric push rod, which drives the position of the movable box 7 to adjust up and down, and adjusts the height of the water level between the support plate 5 and the box body 1, so as to provide sufficient reaction time for the internal sewage and dissolved air.

[0022] In this embodiment, a water pipe 21 is fixed to one end of the sewage inlet pipe 3, and a dissolved air nozzle 26 is fixedly installed on the side of the water pipe 21. A guide rail 11 is welded to the side of the box body 1, and a slide groove 12 is opened on the guide rail 11. A slider 14 is movably installed inside the slide groove 12. A displacement mechanism 13 is fixedly installed at one end of the guide rail 11, and a movable column 16 is installed on the displacement mechanism 13. One end of the movable column 16 is fixed on the slider 14, and a pushing mechanism 15 is fixed to the bottom of the slider 14. A fixed frame 9 is fixedly installed on the top of the pushing mechanism 15, and the inner wall of the fixed frame 9 A connecting plate 17 is fixed, a cleaning box 10 is fixed to the bottom of the connecting plate 17, a fixed pipe 18 is fixed to one side of the cleaning box 10, a connecting pipe 19 is movably installed at one end of the fixed pipe 18, a supporting pipe 20 is movably installed at one end of the connecting pipe 19, and the supporting pipe 20 is fixedly installed at one end of the box body 1. The pushing mechanism 15 and the displacement mechanism 13 are both electric push rods, which push the slider 14 to move horizontally inside the slide groove 12. The horizontal movement of the slider 14 drives the cleaning box 10 on the fixed frame 9 to change its position on the sewage water surface, thereby completing the cleaning and collection of floating objects at different positions.

[0023] The device provides the required electric energy for the electrical appliances inside the device through an external power supply. When using the device, first connect the sewage inlet pipe 3 to the external sewage equipment, and let the sewage enter between the support plate 5 and the box body 1. The dissolved air pipe 4 is connected to the external dissolved air equipment, and the dissolved air is sprayed out from the water pipe 21 and the dissolved air nozzle 26. After the spraying and ventilation, bubbles are generated, and a large number of microbubbles are used to capture and adsorb fine particles and adhesives to make them float, so as to achieve the effect of solid-liquid separation. After the bubbles and particles cooperate, they move upward with the buoyancy of the bubbles, and the rising impurities enter the interior of the movable box 7, and enter the next position reaction through the cooperation of the movable box 7 and the limiting tube 25. When in use, start the lifting mechanism 8 to push the movable rod 23 to move inside the fixed groove 22, and the limiting tube 25 and the movable seat 24 provide vertical limiting force for the movable plate 6. At the same time, the movable plate 6 moves on one side of the fixed groove 22, and the movable plate 6 moves to the fixed groove 22 while moving. The cleaning box 10 on the fixed frame 9 is sealed to avoid the influence caused by the outflow of sewage from the fixed groove 22. When cleaning the impurities on the other side of the support plate 5 at a later time, the displacement mechanism 13 pushes the slider 14 to move inside the slide groove 12 through the movable column 16. When moving, the slider 14 drives the cleaning box 10 on the fixed frame 9 to move forward and backward. The forward and backward movement controls the position of the cleaning box 10, and the floating objects on the water surface at different positions are collected and cleaned. The cleaning box 10 moves up and down under the drive of the pushing mechanism 15, and the height between the cleaning box 10 and the water surface is adjusted according to the thickness of the floating objects, and the floating objects on the water surface enter the interior of the cleaning box 10 to meet the adjustment in different situations. When the cleaning box 10 moves up, down, left and right, the fixed pipe 18 moves up and down inside the connecting pipe 19, and the connecting pipe 19 moves inside the support pipe 20 with the horizontal movement of the cleaning box 10. Later, the floating objects are discharged outward through the fixed pipe 18, the connecting pipe 19 and the support pipe 20.
