Anti-blocking double-pneumatic flap valve

Abstract

The invention belongs to the technical field of flap valves, and aims to solve the problems that an existing flap valve does not have an anti-blocking function and is difficult to ensure that a discharging process is smoothly conducted, a flap of the existing flap valve is generally manually closed or opened, and the control process is time-consuming and labor-consuming, in particular to an anti-blocking double-pneumatic flap valve. The anti-blocking double-pneumatic flap valve comprises a valve body and a vertical hopper, the vertical hopper is installed at the top of the valve body, a vertical partition plate is installed in the middle of the vertical hopper, a flap assembly is installed at the bottom of the vertical hopper, a first anti-blocking assembly is installed in the valve body, a second anti-blocking assembly is installed at the position, close to the bottom, of the vertical partition plate, and a pneumatic control assembly is installed on the outer wall of the valve body. According to the anti-blocking double-pneumatic flap valve, the pneumatic control assembly is arranged to pneumatically control opening and closing of the flap, operation is easy, use is convenient, time and labor are saved, the operation efficiency is remarkably improved, by arranging the first anti-blocking assembly and the second anti-blocking assembly, the situation that an opening is blocked during discharging can be effectively prevented, it is guaranteed that the discharging process is conducted smoothly, and the discharging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of flap valves, in particular based on anti-clogging double pneumatic flap valves. Background technique [0002] The flap valve is used as the ash hopper unloading device of various equipment and the feeding and unloading device of various mills, dryers, silos and other equipment to prevent the wild wind from blowing in, so as to complete the material transportation. Double-door flap valve and double-layer flap valve mainly use the upper and lower valves to switch at different times to keep a layer of valve plate in the middle of the equipment in a closed and isolated state to prevent air channeling. The layer air lock valve can also play the role of balance and booster valve to help the flow, so that the equipment can not only continuously pulsate feeding, but also have the function of air lock, so as to meet the requirements of pneumatic conveying powder and granular materials; [0003] When the existing ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a dual pneumatic flap valve based on anti-clogging, which can pneumatically control the opening and closing of the flap by setting the pneumatic control component, which is simple to operate, convenient to use, saves time and effort, and significantly improves the operating efficiency. The first anti-blocking component and the second anti-blocking component can effectively prevent the opening from being blocked during unloading, ensure the smooth progress of the unloading process, improve the unloading efficiency, and solve the problem that the existing flap valve does not have an anti-blocking function , can not effectively prevent the unloading opening from being blocked, and it is difficult to ensure the smooth progress of the unloading process, and when the opening is blocked, it is necessary to manually clear the opening through tools, which is not only troublesome, but also further affects the unloading process The smooth progress of the operation reduces the unloading efficiency, and the existing flap valves are generally closed or opened manually, the control process is time-consuming and laborious, and it is not conducive to improving the operating efficiency, which needs to be improved.
