[0002] In the technical field of anhydrous hydrogen fluoride production, it is usually necessary to inject fluorite and concentrated sulfuric acid as production materials into a fluoridation furnace through a filling pipe, and circulate steam into a spiral tube to heat the fluoridation furnace and the production materials. At the same time, a motor is required to drive a stirring plate to rotate through a rotating rod, so that the stirring plate uses the rotational power to stir and mix the fluorite and concentrated sulfuric acid materials in the fluoridation furnace, so that the fluorite and concentrated sulfuric acid react chemically with heating during the stirring process, thereby generating anhydrous hydrogen fluoride gas and discharging it from a flange pipe. However, conventional anhydrous hydrogen fluoride production equipment still has problems in actual operation.

[0003] For example, in the actual operation process, the position for adding materials into the fluorination furnace is a fixed position. After the materials enter the fluorination furnace, they are usually accumulated in a large amount near the filling port of the fluorination furnace, which leads to uneven material filling.

[0127] In the actual application of this embodiment, when the motor 8 is started to drive the rotating rod 9 to rotate clockwise, the staff needs to control the extension of the electric rod 21, so that the electric rod 21 uses the telescopic end to push the L plate 22 under the support of the fluorination furnace 1, so that the L plate 22 drives the rotating shaft 23 to move in the direction away from the fixed end of the electric rod 21 under the action of external force, and at the same time, the rotating shaft 23 drives the rubber wheel 24 and the support plate 27 to move in the direction away from the fixed end of the electric rod 21, and then the rubber wheel 24 is translated to between the transmission wheel 25 and the rubber wheel 26, and is in close contact with the transmission wheel 25 and the rubber wheel 26, so that the motor 8 can pass through the rotating rod 9 and the transmission The wheel 25 utilizes friction force to push the rubber wheel 24 and the rotating shaft 23 to rotate counterclockwise under the support of the L plate 22. At the same time, the rubber wheel 24 utilizes friction force and rotational power to push the rubber wheel 26 to rotate clockwise, so that the rubber wheel 26 can utilize external force to drive the screw 15 to rotate clockwise under the support of the fluorination furnace 1, and then the screw 15 utilizes rotational power and thread to push the rubber ring 36, so that the rubber ring 36 drives the arc tube 16 to slowly and uniformly move in the direction away from the filling pipe 11 under the resistance limit of the fluorination furnace 1. When the arc tube 16 moves in the direction away from the filling pipe 11, it will gradually stretch and unfold the folding tube 14 under the support of the filling pipe 11.

[0128] When the electric rod 21 is extended, the L plate 22 will drive the push plate 28 to move in the direction close to the frame cover 18 through the support plate 27, so that the push plate 28 uses external force to push the frame plate 31, and the frame plate 31 uses external force to push the push plate 30 to pass through the through hole 34 and move in the direction away from the push plate 28 along the track groove 35, and push the support plate 32 during the movement, so that the support plate 32 drives the sealing gasket 33 to move in the direction away from the push plate 28, so that the sealing gasket 33 covering the discharge port 17 is removed, and then the discharge port 17 is opened, so that the material entering the arc tube 16 can be discharged into the fluorination furnace 1 through the discharge port 17, and at the same time, the material in the filling hopper 12, the filling pipe 11 and the folding pipe 14 will gradually enter the arc tube 16 and be discharged through the discharge port 17, and the slow and uniform translation of the arc tube 16 is used to evenly fill the material into the fluorination furnace 1.

[0129] When the arc tube 16 translates, the frame cover 18 will move together. Under the action of external force, the frame cover 18 will drive the push plate 30 to move together through the track groove 35, so that the push plate 30 drives the support plate 32, the sealing gasket 33 and the frame plate 31 to move together, so that the push plate 30 can drive the frame plate 31 to translate together along the guide groove 29 in the direction away from the filling pipe 11 under the support of the guide push plate 28.

[0130] When the arc tube 16 drives the switch 37 to move to the extreme position in the direction away from the filling pipe 11, the switch 37 will contact the fluorination furnace 1 under the support of the arc tube 16, and squeeze the switch 37 under the action of external force and the resistance of the fluorination furnace 1, so that the switch 37 is squeezed and triggered, thereby controlling the electric rod 21 to contract, and then the telescopic end of the electric rod 21 drives the rubber wheel 24 to move in the direction close to the fixed end of the electric rod 21 through the L plate 22 and the rotating shaft 23, so that the rubber wheel 24 is separated from the rubber wheel 26 and the transmission wheel 25, and then the screw 15 stops rotating clockwise, and the stretched and energy-storing spring 20 uses the rebound force to pull the arc tube 16 in the direction close to the filling pipe 11 under the support of the fluorination furnace 1, so that the arc tube 16 drives the rubber ring 36 to move together, so that the rubber ring 36 uses the external force and the thread to push the screw 15 to rotate under the support of the fluorination furnace 1, so that the arc tube 16 can move and reset.

[0131] In another preferred embodiment of the present invention, the protection unit comprises:

[0132] The actuator is rotatably connected to the side of the transmission wheel 25 close to the arc tube 16 and is located below the folding tube 14;

[0133] A push member connected to the actuator and arranged on one side of the rubber wheel 24, corresponding to the position of the actuator;

[0134] The push-pull parts include:

[0135] The arc connecting plate 42 is fixed below the actuator;

[0136] The arc support plate 43 is fixed to one end of the arc connecting plate 42 away from the actuator.

[0137] Specifically, the executive parts include:

[0138] A support ring 39 is fixed to a side of the rubber wheel 26 close to the arc tube 16;

[0139] The bearing 40 is sleeved on the outer side of the support ring 39;

[0140] The arc push plate 41 is fixed on the bearing 40 .

[0141] The rubber wheel 26 can provide a stable support for the support ring 39, the support ring 39 can provide a support for the bearing 40, and the bearing 40 can provide a rotation support for the arc push plate 41. The arc push plate 41 has an arc and is located below the folding tube 14;

[0142] Specifically, the push member also includes:

[0143] There are four levers 38, which are evenly fixed on a side of the rubber wheel 24 away from the motor 8, and one end away from the rubber wheel 24 is an arc structure;

[0144] The counterweight block 44 is fixed on the outer side of the arc support plate 43 , and the counterweight block 44 is heavier than the arc push plate 41 .

[0145] The rubber wheel 24 can provide stable support for the lever 38, and can use the rotational power to drive the lever 38 to rotate together, and the bearing 40 can provide support for the arc connecting plate 42, so that the arc connecting plate 42 can stably support the arc support disk 43, and the arc support disk 43 can provide stable support for the counterweight block 44. The counterweight block 44 can cooperate with the bearing 40 to use gravity to prevent the counterweight block 44, the arc push plate 41, the arc connecting plate 42 and the arc support disk 43 from rotating with the support ring 39 and the rubber wheel 26. The rubber wheel 26 will drive the support ring 39 to rotate on the inner side of the bearing 40.

[0146] In the actual application of this embodiment, when the electric rod 21 is extended to drive the rubber wheel 24 to contact the transmission wheel 25, the rubber wheel 24 will use the rotational power to drive the lever 38 to rotate counterclockwise, so that the lever 38 uses the rotational power to contact the arc support plate 43, and pushes the counterweight block 44 and the arc connecting plate 42 through the arc support plate 43, so that the arc connecting plate 42 pushes the bearing 40 to rotate clockwise with the bearing 40 as the center under the support of the support ring 39. At the same time, the bearing 40 will use the rotational power to drive the arc push plate 41 to rotate clockwise, and then the lever 38 will rotate along the rotating arc support plate as it rotates. 43 moves and gradually separates from the arc support plate 43 as it rotates, and then the counterweight block 44 uses its own gravity to push the arc support plate 43, so that the arc support plate 43 uses gravity to drive the bearing 40 to rotate counterclockwise and reset under the support of the support ring 39 through the arc connecting plate 42, and then the bearing 40 drives the arc push plate 41 to rotate and reset together, waiting to be pushed by the lever 38 next time, and so on, so that the arc push plate 41 can reciprocate and push the folding tube 14 upward to deform, so that the folding tube 14 can push the material inside it under the action of external force, thereby preventing material blockage and facilitating the unblocking of materials.

[0147] As a preferred embodiment of the present invention, a method for using an anhydrous hydrogen fluoride production device is provided, and the method for using includes:

[0148] The materials for the production of anhydrous hydrogen fluoride are injected into the inner side of the arc cylinder 16 through the filling hopper 12, the filling pipe 11 and the folding pipe 14 to temporarily store the materials;

[0149] The motor 8 is started to drive the stirring plate 10 and the transmission wheel 25 to rotate through the rotating rod 9, and the electric rod 21 is controlled to extend, so as to push the rubber wheel 24 to contact and fit with the transmission wheel 25 and the rubber wheel 26, so as to promote the rotation of the screw 15;

[0150] When the electric rod 21 is extended, the L plate 22 pushes the sealing gasket 33 to translate along the frame cover 18 in a direction away from the push plate 28 through the push plate 28, the frame plate 31, the push plate 30 and the support plate 32, so as to open the discharge port 17;

[0151] The screw 15 rotates and uses the threaded action with the rubber ring 36 to push the arc tube 16 to translate in a direction away from the filling pipe 11, and stretches the folding tube 14 and the spring 20 during the translation process. At the same time, the temporarily stored material will pass through the discharge port 17 and fall in a direction close to the rotating rod 9, so as to evenly distribute the material for the production of anhydrous hydrogen fluoride in the fluorination furnace 1, and the rotating stirring plate 10 is used to stir the material;

[0152] When the rubber wheel 24 is in contact with the transmission wheel 25 and the rubber wheel 26, it will drive the wave-pushing member to rotate, so that the arc support plate 43 in the wave-pushing member pushes the actuator through the arc connecting plate 42 under the support of the rubber wheel 26, so as to move and clear the material in the folding tube 14 when the material is evenly distributed in translation.

[0153] Working principle: the material enters the filling pipe 11 through the filling hopper 12, and then is injected into the arc cylinder 16 located in the fluorination furnace 1 through the folding tube 14, and then the motor 8 is started. Through the connection between the shaft cover 7 and the rotating rod 9, the motor 8 drives the rotating rod 9 to drive the stirring plate 10 to rotate in the fluorination furnace 1. The stirring plate 10 utilizes the rotation effect to fully stir the filled material in the fluorination furnace 1, thereby promoting the mixing of the materials and preparing for the reaction to generate anhydrous hydrogen fluoride gas.

[0154] When the motor 8 is started, the extension of the electric rod 21 is controlled to push the L plate 22, so that the rubber wheel 24 contacts the transmission wheel 25 and the rubber wheel 26, so that the screw 15 rotates. The rotation of the screw 15 pushes the rubber ring 36 and the arc tube 16 to move horizontally through the thread action, and at the same time, the discharge port 17 is opened to discharge the temporarily stored materials into the fluorination furnace 1, so that the temporarily stored materials are evenly distributed in the fluorination furnace 1. The fluorination furnace 1 is heated by the steam in the spiral tube 4, so that the materials react chemically in the fluorination furnace 1 to generate anhydrous hydrogen fluoride gas. The generated gas is discharged through the flange pipe 6 and enters the gas delivery pipeline.

[0155] The push-pushing member cooperates with the rubber wheel 26 and the actuator through the arc support plate 43, the arc connecting plate 42, and the rotation of the rubber wheel 26 drives the arc support plate 43 and the counterweight block 44 to rotate clockwise. When the arc support plate 43 contacts the lever 38, the counterweight block 44 is reset counterclockwise by gravity, forming a reciprocating movement effect to prevent material blockage.

[0156] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
