The slag is dropped into the storage chamber through a discharge hole through a central funnel, and enters the discharge chamber through a lowering port at the bottom of an inclined plate inclined on one side. Then, when the slag needs to be discharged, the solenoid valve A is closed, and then the exhaust fan works to discharge the gas in the storage chamber and the discharge chamber back into the hydrofluoric acid reactor body through the air outlet pipe and the air inlet pipe. Then, the solenoid valve B is opened, and the spiral auger is rotated under the action of the motor, so that the slag is discharged through the discharge port, thereby completing the slag discharge work of the hydrofluoric acid reactor and avoiding the discharge of internal gas, making the safety performance higher and reducing gas leakage.

The connecting ring moves upward to drive the stabilizing frame upward, and the stabilizing frame moves upward to drive the T-shaped rod upward. When the T-shaped rod moves upward and is aligned with the fixed groove, release the T-shaped rod; Step 3: The T-shaped rod is loosened so that the T-shaped rod moves toward the slag discharge pipe under the elastic force of the No. 1 spring, and the T-shaped rod moves toward the slag discharge pipe and contacts the fixing groove to fix the slag discharge pipe and the recovery frame; Step 4: After the slag discharge pipe and the recovery frame are fixed and stable, start the electric valve to release the seal of the reactor body.

[0015] The present invention provides a slag discharging device for a hydrofluoric acid reaction furnace. It has the following beneficial effects: (1) The invention places a recovery frame at the bottom of the slag discharge pipe and aligns the auxiliary groove with the arc rod. After the auxiliary groove is aligned with the arc rod, the recovery frame and the connecting ring are pushed upward to contact the slag discharge pipe. The leakage of hydrofluoric acid or other corrosive substances can be effectively prevented through precise docking, thereby reducing harm to the environment and operators. After the limit of the slag discharge pipe is released, the recovery frame moves downward under the action of its own gravity. The recovery frame moves downward under the action of its own gravity and is disconnected from the slag discharge pipe. The time of the slag discharge operation can be reduced through quick docking and disassembly, thereby shortening the production cycle and improving the overall work efficiency. The quick docking design facilitates regular inspection and cleaning, reducing the complexity of equipment maintenance.

[0016] (2) The invention moves the clamping plate toward the slag discharge pipe to contact the slag discharge pipe and perform auxiliary clamping and fixing on the slag discharge pipe. The auxiliary clamping and fixing can prevent the slag discharge pipe from displacement or vibration during operation, reduce the risk of waste slag leakage caused by looseness of the slag discharge pipe and the recovery frame, thereby ensuring the safety of the operator. The inclined plate moves toward the direction away from the slag discharge pipe to drive the protrusion to move. The movement of the protrusion hits the recovery frame to generate vibration. The vibration can accelerate the falling and flow of the waste slag, thereby improving the slag discharge efficiency, reducing the slag discharge time and making the slag discharge process more efficient.

[0017] (3) In the present invention, the upward movement of the L-shaped rod drives the limit plate to move upward. The limit plate moves upward to disengage from the limit groove and release the limit on the driving button. After the limit of the driving button is released, the driving button is manually pressed. The driving button is pressed to drive the electric valve to release the seal of the reactor body. Unstable docking will cause waste slag to accumulate at the joint. By ensuring stable docking before performing the slag discharge operation, the slag discharge pipe can be kept unobstructed. Stable docking can effectively avoid leakage of waste slag, further preventing corrosive substances from causing harm to the environment and operators. BRIEF DESCRIPTION OF THE DRAWINGS

A slag discharge device for a hydrofluoric acid reaction furnace according to claim 5, characterized in that: The protection device comprises a protection groove (171), a protection frame (172), a protection rod (173), an L-shaped rod (174), a limiting plate (175), a driving button (176) and a limiting groove (177); the protection groove (171) is formed on the circumferential surface of the slag discharge pipe (6); the protection frame (172) is fixedly mounted on the inner wall of the protection groove (171); the protection rod (173) slides through the inner and outer walls of the protection frame (172); the L-shaped rod (174) is fixedly mounted on the top of the protection rod (173); the limiting plate (175) is fixedly mounted on an end of the L-shaped rod (174) away from the slag discharge pipe (6); the driving button (176) is fixedly mounted on the front side of the protection frame (172); and the limiting groove (177) is formed on the circumferential surface of the driving button (176).

7. A slag discharge device for a hydrofluoric acid reaction furnace according to claim 6, characterized in that: The L-shaped rod (174) contacts the inner wall of the protection groove (171), a No. 2 spring is provided between the protection frame (172) and the protection rod (173), and one end of the L-shaped rod (174) close to the recovery frame (7) is provided as an inclined surface.

8. A slag discharge device for a hydrofluoric acid reaction furnace according to claim 7, characterized in that: The L-shaped rod (174) is in contact with the clamping plate (166), the driving button (176) is electrically connected to the electric valve (5), and the L-shaped rod (174) penetrates the inner and outer walls of the protection frame (172).

9. A method for using a slag tapping device for a hydrofluoric acid reaction furnace, using the slag tapping device for a hydrofluoric acid reaction furnace according to claim 8, characterized in that: The following steps are involved: Step 1: When the slag inside the reactor body (2) is discharged, the T-shaped rod (13) is first manually pulled to move away from the connecting ring (9), and at the same time, the recovery frame (7) is manually placed at the bottom of the discharge pipe (6) and the auxiliary groove (10) is aligned with the arc rod (11); Step 2: After the auxiliary groove (10) is aligned with the arc rod (11), the recovery frame (7) and the connecting ring (9) are pushed upward to contact the slag discharge pipe (6), the connecting ring (9) moves upward to drive the stabilizing frame (12) to move upward, the stabilizing frame (12) moves upward to drive the T-shaped rod (13) to move upward, and when the T-shaped rod (13) moves upward to align with the fixing groove (14), the T-shaped rod (13) is released; Step 3: The T-shaped rod (13) is loosened so that the T-shaped rod (13) moves toward the slag discharge pipe (6) under the elastic force of the first spring. The T-shaped rod (13) moves toward the slag discharge pipe (6) and contacts the fixing groove (14) to fix the slag discharge pipe (6) and the recovery frame (7). Step 4: After the slag discharge pipe (6) and the recovery frame (7) are fixed and stable, the electric valve (5) is started to release the seal of the reactor body (2). After the seal of the reactor body (2) is released, the slag inside the reactor body (2) enters the recovery frame (7) through the slag discharge pipe (6) under the action of its own gravity for slag discharge.
