Description

Technical Field

[0001] This utility model relates to the field of turbid circulating water treatment technology in steel rolling mills, specifically to an integrated filter tank exhaust device. Background Technology

[0002] Steel rolling mill turbid circulating water filter tanks utilize filter media to filter impurities in turbid circulating water, thereby obtaining a relatively pure fluid. Commonly used filter tanks in production are integrated filter tanks that combine filtration and purification functions. Their principle is mainly based on the selective blocking of filter media (such as filter paper, filter membranes, filter screens, etc.) to remove suspended solids, silt, rust, and other impurities from the fluid, thus achieving water purification. The vent valve located at the top of the tank plays a crucial role in the filtration system.

[0003] The main function of the vent valve is to discharge the gas generated by the integrated filter tank during water supply, ensuring the efficient operation of the filtration system. Research and improvement of vent valves are ongoing, as exemplified by patent application number 202020688337.7 and publication number CN 212615678U. This patent describes a float vent valve, whose basic principle includes a valve body and a valve cover. The valve body has a liquid inlet, the valve cover has a vent port, a valve seat is located inside the vent port, and the valve seat has an air hole. A vent plug with an inner hole is located in the vent port above the valve seat. The valve seat is fixedly connected to a lever frame, which is connected to a float via a lever assembly. A valve disc that mates with the lower end of the valve seat is fixedly connected to the lever assembly. The float is located below the lever assembly, and its lower part has a concave spherical surface. As the water level rises or falls, the float moves the lever assembly, which in turn moves the valve disc upwards to engage with the valve seat or downwards away from it, thus effectively venting the gas while preventing water from overflowing the tank.

[0004] However, due to the presence of a large amount of suspended solids, silt, rust, and other impurities in the turbid circulating water, these impurities will be retained at the contact point between the valve disc and the valve seat when the water level rises to the bottom of the valve seat. This results in impurities between the valve disc and the valve seat, preventing the valve disc and valve seat from closing tightly. Consequently, the air vent valve cannot effectively seal the water inside the tank. At this point, the water inside the tank will overflow through the air vent valve and flow along the outer wall of the tank, which will corrode the outer wall of the tank over time. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated filter tank exhaust device to solve the problem that water inside the integrated filter tank in the above-mentioned patent will overflow through the exhaust valve and corrode the outer wall of the tank.

[0006] To achieve the above object, the utility model provides a basic scheme: An integrated filter tank exhaust device, including valve shell and valve core, the inner wall of valve shell is fixed with support plate, support plate is fixed with vertical plate, support plate is connected with valve core seat, vertical plate is equipped with the connecting assembly for connecting vertical plate and valve core, valve core is sleeved with valve core seat, one end of valve core away from connecting assembly is fixed with floating plate, the opening of valve shell is bolted with gland, and the overflow pipe is communicated with the overflow pipe.

[0007] The utility model discloses a principle and beneficial effect lies in: through setting up support plate and separating exhaust valve into two parts, the valve core seat of the support plate is used to limit the orientation of the valve core, and the floating plate fixed to one end of the valve core makes the valve core not separate from the valve core seat due to water pressure, when the water in the tank rises to the height where the floating plate is located, the floating plate will rise due to water pressure until it is attached to the valve core seat, and the water is blocked below the support plate to prevent the water in the tank from overflowing out of the tank body, when there are impurities between the valve core seat and the floating plate, as the water level rises, the air and water in the tank will flow to the overflow pipe through the gap between the valve core and the valve core seat, and finally, the tank body is discharged through the overflow pipe, and the end of the overflow pipe is outside the tank body. The above-mentioned exhaust valve can realize effective exhaust without water overflowing out of the tank body to corrode the outer wall of the tank body.

[0008] Scheme two, this is the preferred of basic scheme, connecting assembly includes connecting rod and ear seat, connecting rod is hinged with vertical plate, ear seat is hinged with connecting rod, and ear seat is fixed with valve core. The connecting rod and the ear seat are connected in a movable shaft mode, so that the valve core can float up and down with the water pressure, which facilitates preventing excessive overflow of water when the water level rises, and facilitates normal exhaust when the water level does not change, and facilitates normal air intake when the water level drops.

[0009] Scheme three, this is the preferred of basic scheme, the outer surface of the valve core and the inner surface of the valve core seat are provided with inclined surfaces. When the gas enters and exits, the valve core will not displace, when the water level rises to the floating plate, the inclined surface on the valve core and the inclined surface on the valve core seat are attached, the greater the water pressure, the closer the two inclined surfaces will be attached, and the more effectively the water overflow is prevented.

[0010] Scheme four, this is the preferred of basic scheme, the connecting part of valve shell and gland is provided with sealing strip. The sealing strip is arranged on the valve shell along the connecting part of the gland to seal, preventing water or gas leakage of the valve shell.

[0011] Scheme five, this is the preferred of basic scheme, the overflow pipe is communicated with the flow guide pipe, and the flow guide pipe is communicated with the air pipe. The flow guide pipe can guide the water in the overflow pipe into the sewage ditch to prevent sewage from polluting the environment, and the air pipe can realize air intake and exhaust of the exhaust valve. When the water level in the tank drops, air is sucked, and when the water level in the tank rises, air is exhausted. DRAWINGS
