[0019] The present invention provides a slag discharging device for a hydrofluoric acid reaction furnace. It has the following beneficial effects:

[0020] (1) In this invention, by placing the recycling box at the bottom of the slag discharge pipe and aligning the auxiliary groove with the arc-shaped rod, after the alignment of the auxiliary groove and the arc-shaped rod, the recycling box and the connecting ring are pushed upward to contact the slag discharge pipe. Through precise docking, the leakage of hydrofluoric acid or other corrosive substances can be effectively prevented, thereby reducing the harm to the environment and operators. After the limit of the slag discharge pipe is released, the recycling box moves downward under its own gravity, and the recycling box moves downward under its own gravity to disconnect from the slag discharge pipe. Through quick docking and disassembly, the time of slag discharge operation can be reduced, thereby shortening the production cycle and improving the overall work efficiency. And the design of quick docking is convenient for regular inspection and cleaning, reducing the complexity of maintaining the equipment.

[0021] (2) In this invention, the clamping plate moves towards the slag discharge pipe to contact and assist in clamping and fixing the slag discharge pipe. Through the auxiliary clamping and fixing, the displacement or vibration of the slag discharge pipe during operation can be prevented, reducing the risk of waste residue leakage caused by loosening of the slag discharge pipe and the recycling box, thereby ensuring the safety of operators. The inclined panel moves away from the slag discharge pipe to drive the convex block to move, and the movement of the convex block impacts the recycling box to generate vibration. Through vibration, the falling and flowing of the waste residue can be accelerated, thereby improving the slag discharge efficiency, reducing the slag discharge time and making the slag discharge process more efficient.

[0022] (3) In this invention, the L-shaped rod moves upward to drive the limit plate to move upward.

[0035] One end of the T-shaped rod 13 close to the slag discharge pipe 6 is set as an arc surface. A through hole is opened on the circumferential surface of the connection ring 9. The T-shaped rod 13 contacts the inner wall of the through hole. The T-shaped rod 13 moves away from the connection ring 9 and disengages from the contact with the fixing groove 14, and the limit on the slag discharge pipe 6 is released.

[0036] A using method of a slag discharging device for a hydrofluoric acid reaction furnace, using the above-mentioned slag discharging device for a hydrofluoric acid reaction furnace, includes the following steps:

[0037] Step 1: When discharging the slag inside the reaction furnace body 2, first manually pull the T-shaped rod 13 to move away from the connection ring 9, and at the same time manually place the recovery box 7 at the bottom of the slag discharge pipe 6 and align the auxiliary groove 10 with the arc-shaped rod 11;

[0038] Step 2: After the auxiliary groove 10 is aligned with the arc-shaped rod 11, push the recovery box 7 and the connection ring 9 upward to contact the slag discharge pipe 6. The upward movement of the connection ring 9 drives the stabilizing frame 12 to move upward, and the upward movement of the stabilizing frame 12 drives the T-shaped rod 13 to move upward. When the T-shaped rod 13 moves upward and aligns with the fixing groove 14, release the T-shaped rod 13;

[0039] 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, and the T-shaped rod 13 moves toward the slag discharge pipe 6 to contact the fixing groove 14 and fix the slag discharge pipe 6 and the recovery frame 7;

[0040] Step 4: After the slag discharge pipe 6 and the recovery frame 7 are fixed and stable, start the electric valve 5 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.

[0041] When the present embodiment is working: when it is necessary to discharge the slag inside the reactor body 2, the T-shaped rod 13 is first manually pulled in a direction away from the connecting ring 9, and the T-shaped rod 13 moves in a direction away from the connecting ring 9 to pull the No. 1 spring, which is pulled by the T-shaped rod 13 to deform and accumulate force. At the same time, the recovery frame 7 is manually placed at the bottom of the slag discharge pipe 6 and the auxiliary groove 10 is aligned with the cambered rod 11. After the auxiliary groove 10 is aligned with the cambered rod 11, the recovery frame 7 and the connecting ring 9 are pushed to move upward and contact the slag discharge pipe 6. The connecting ring 9 moves upward to drive the stabilizing frame 12 to move upward, and the stabilizing frame 12 moves upward to drive the T-shaped rod 13 to move upward. When the T-shaped rod 13 moves upward and is aligned with the fixing groove 14, the T-shaped rod 13 is released. The T-shaped rod 13 is released so that the T-shaped rod 13 is under the elastic force of the No. 1 spring. Move downward in the direction close to the slag discharge pipe 6, the T-shaped rod 13 moves in the direction close to the slag discharge pipe 6, contacts with the fixed groove 14 and fixes the slag discharge pipe 6 and the recovery frame 7. After the slag discharge pipe 6 and the recovery frame 7 are fixed and stable, start the electric valve 5 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. After the slag discharge operation is completed, manually pull the T-shaped rod 13 to move away from the connecting ring 9. The T-shaped rod 13 moves in the direction away from the connecting ring 9 to break away from the contact with the fixed groove 14 and release the limit on the slag discharge pipe 6. After the limit of the slag discharge pipe 6 is released, the recovery frame 7 moves downward under the action of its own gravity, and the recovery frame 7 moves downward under the action of its own gravity to break away from the connection with the slag discharge pipe 6.

The linkage plate 15 moves back to its original position and disengages from the contact with the inclined panel 162. When the inclined panel 162 disengages from the contact with the linkage plate 15, the sliding rod 161 moves back to its original position towards the slag discharge pipe 6 under the elastic force of the clamping spring 165. The sliding rod 161 moves back to its original position towards the slag discharge pipe 6 and drives the inclined panel 162 and the clamping plate 166 to move. The clamping plate 166 moves towards the slag discharge pipe 6 and contacts the slag discharge pipe 6 and assists in clamping and fixing the slag discharge pipe 6. At the same time, the inclined panel 162 moves away from the slag discharge pipe 6 and drives the convex block 164 to move.

The upward movement of the protection rod 173 pulls the second spring. The second spring deforms under the pull of the protection rod 173. At the same time, the upward movement of the L-shaped rod 174 drives the limiting plate 175 to move upward. The upward movement of the limiting plate 175 disengages from the limit of the limiting groove 177 and releases the limit on the driving button 176. After the limit on the driving button 176 is released, manually press the driving button 176. The driving button 176 is pressed to drive the electric valve 5 to operate and release the seal of the reaction furnace body 2. When the clamping plate 166 moves away from the slag discharge pipe 6, the clamping plate 166 moves away from the contact with the L-shaped rod 174. When the L-shaped rod 174 disengages from the contact with the clamping plate 166, the protection rod 173 moves downward to its original position under the elastic force of the second spring. The downward movement of the protection rod 173 drives the L-shaped rod 174 to move downward. The downward movement of the L-shaped rod 174 drives the limiting plate 175 to move downward.
