Description

Technical Field

[0001] The utility model relates to the technical field of air flotation machines, in particular to a water level valve device for an air flotation machine. Background Art

[0002] The flotation machine is a device that injects a large number of fine bubbles into the water, making these bubbles attach to the suspended particles. Since the density of bubbles is less than that of water, the buoyancy principle is used to make these particles float to the water surface, thereby achieving solid-liquid separation. After the particles float to the water surface in the scum pool and retain a certain thickness, they are scraped into the scum tank for discharge.

[0003] However, the water level of the scum pool in the traditional air flotation machine is controlled by the flow limiting valve in the clean water tank, so that the water level is constant at a certain height to prevent the water level from being higher than the height of the scum tank and causing a large amount of drainage. However, at the end of the equipment operation, since the water level has always been lower than the scum tank, there are still many particles on the water surface of the scum pool. In order to solve this pain point, the traditional flow limiting valve needs to be raised and lowered to increase the water level of the scum pool. However, since the height of the flow limiting valve is controlled by rotating the hand wheel, and it is necessary to climb onto the equipment to operate it, the operation is more troublesome and the efficiency is relatively low. Utility Model Content

The lower end of the nozzle cylinder is connected to the scum pool through a connecting pipe. The lifting assembly is connected to a handle assembly, which is mounted on the outer wall of the machine body.

[0011] In the above-mentioned flotation machine water level valve device, the handle assembly includes a first connecting rod fixedly mounted on a rotating shaft, one end of the first connecting rod is hinged to a second connecting rod, the second connecting rod is located on the outside of the machine body, the lower end of the second connecting rod is hinged to the upper surface of the handle, and one end of the handle is mounted on the outer wall of the machine body through a hinge seat.

[0013] The beneficial effect of the utility model is that the height of the nozzle cylinder can be adjusted by the handle assembly on the outer wall of the body, so that when the equipment ends, the height of the nozzle cylinder can be quickly lifted, thereby raising the water level of the scum pool, so that the water surface height is higher than the scum tank, so that after the equipment ends, the particles on the water surface can be quickly discharged into the scum tank, thereby draining the undischarged scum and preventing the particles from staying on the water surface, and the operator does not need to climb to the height of the equipment to operate the flow limiting cylinder, which is simple to operate and highly efficient; the flow limiting cylinder can limit the water level of the scum pool when the equipment is working normally, so that the water level is constant at a certain height to prevent a large amount of drainage.
