Embodiment Construction

[0027] as attached figure 1 As shown, a pneumatic slag discharge valve includes a slag discharge valve, a driving mechanism, a position sensor unit and a central control room. The slag discharge valve and the driving mechanism are connected together through a bracket 5. Body 3, hollow metal O-ring 12, sealing packing 13, valve body 3 is provided with a slag discharge channel, and the gate 1 moves to realize the opening and closing of the slag discharge channel in the valve body 3. The driving mechanism controls the opening and closing of the slag discharge valve by driving the movement of the gate 1. The position sensor unit is arranged on the bracket, and the central control room is connected with the position sensor unit. The position sensor unit can sense the movement information of the piston rod and send it to the central control unit. Room, the central control room is used to control the action of the drive mechanism. The driving mechanism includes a compressed air sour...

Abstract

The invention relates to a pneumatic residual cake valve which comprises a residual cake valve, a driving mechanism, a position sensor unit, a support and a central control room; the residual cake valve comprises a valve body and a movable flashboard, wherein a vertical passage is arranged on the valve body, a flow guide hole is arranged on the flashboard, and a sealing device is arranged between the flashboard and the valve body; a furnace bottom flange is arranged on one end surface of the passage, and a pipe flange is arranged on the other end surface of the passage; the driving mechanism comprises a compressed air source, a solenoid directional valve, a cylinder, a piston arranged in the cylinder and a piston rod; the piston divides the cylinder into a first air chamber and a second air chamber, a first air passage is communicated with the first air chamber, and a second air passage is communicated with the second air chamber; and the position sensor unit comprises a position sensor and a positioning ring. The pneumatic residual cake valve solves the technical problems that molten ash residue cannot be discharged and automatic opening and closing of a valve cannot be realized. The pneumatic residual cake valve can realize continuous and automatic control on the opening and closing of the valve and can detect the opening and closing time of the valve in real time.

Description

technical field [0001] The invention relates to a slag discharge valve which can regularly and automatically discharge molten ash. Background technique [0002] The gasifier of pulverized coal dry direct gasification system needs to automatically discharge molten ash from the bottom regularly, but there is no suitable valve to realize continuous and automatic valve opening and closing state control. Contents of the invention [0003] The object of the present invention is to provide a pneumatic slag discharge valve, which can realize continuous and automatic control of the opening and closing of the valve, and can detect the opening and closing time of the valve in real time, which solves the problem that the existing valve cannot be used to discharge molten ash, The automatic opening and closing of the valve cannot be realized, and the technical problems of inconvenient detection. [0004] Technical solution of the present invention: [0005] A pneumatic slag discharge ...
