Description

Technical Field

[0001] This utility model relates to the field of terbium fluoride processing technology, specifically a heating furnace for crude terbium fluoride processing. Background Technology

[0002] The most common dry process for preparing terbium fluoride involves reacting anhydrous hydrogen fluoride gas with terbium oxide. In a dry fluorination apparatus, hydrogen fluoride gas is introduced into the reactor to react with the terbium oxide inside, yielding the final terbium fluoride.

[0003] A search revealed a dry fluorination apparatus for preparing terbium fluoride, with publication number CN217077003U. This application utilizes a dispersion rod and a dispersion plate to better disperse the raw materials, resulting in a more thorough reaction and preventing the raw materials from adhering to the bottom.

[0004] However, the following drawbacks were found in practical applications of this device: During material discharge after the reaction, the fixed baffles and dispersing rods hinder the smooth discharge of terbium fluoride products, leading to reduced discharge efficiency and potentially affecting the purity of the next batch due to material residue. Furthermore, the inability to retract or avoid the discharging rods and baffles during the discharge phase limits the device's applicability in continuous production and increases the difficulty of manual cleaning and maintenance. Utility Model Content

[0007] The storage component includes:

[0008] Circular plate one is used to drive the synchronous radial movement of each component;

[0009] Long rod two is used to drive circular plate one to rotate synchronously;

[0010] Connector, used for stabilizing long rods.

[0011] Preferably, the turning assembly includes a fixed cylinder rotatably connected to the left end of the inner wall of the furnace body. A turning rod is provided inside the fixed cylinder, passing through the fixed cylinder and slidably connected to it. A connecting cylinder is fixed to the left end of the fixed cylinder, passing through the furnace body and rotatably connected to it.

[0012] Preferably, the circular plate is rotatably connected to the inner wall of the fixed cylinder. A connecting hole is provided on the outer surface of the circular plate.

A stabilizing frame is fixed to the left end of the furnace body. A worm is rotatably connected to the inner side of the stabilizing frame. A motor is fixed to the outer surface of the stabilizing frame. The output shaft of the motor passes through the stabilizing frame and is fixed to the outer surface of the worm. The worm meshes with the worm wheel. When the motor is started, the worm drives the worm wheel and the rotating rod to rotate. The circular plate rotates accordingly. The inner wall of the connecting hole contacts the long rod, pushing each long rod and the flipping rod to retract radially away from the inner wall of the furnace body.

[0013] Preferably, the connector includes a cavity formed inside the worm gear. A second circular plate is rotatably connected to the inner wall of the cavity. A second connecting hole is formed on the outer surface of the second circular plate. A short rod abuts against the inner wall of the second connecting hole.

The side of the clamping block away from the second circular plate is slidably connected to the inner wall of the cavity. A T-shaped plate is fixed to the side of the clamping block away from the second circular plate.

When the motor four is turned on, the screw rotates, causing the T-shaped plate to move towards the fixed plate. The clamping block moves towards the long rod two and pushes the short rod, so that the short rod contacts the inner wall of the second connecting hole, driving the second circular plate to rotate. This, in turn, drives the short rod and the clamping block to move radially, so that the clamping block passes through the through hole and clamps the long rod two, facilitating the subsequent synchronous rotation of the long rod two and the first circular plate.

[0016] Compared with the prior art, this utility model provides a heating furnace for crude terbium fluoride production, which has the following advantages:

[0017] 1. This terbium fluoride crude refining furnace, through its set-up receiving components, activates motor four, causing the screw to move the T-shaped plate towards the fixed plate, synchronously advancing the clamping blocks. The clamping blocks push the contact rod, bringing it into contact with the inner wall of the connecting hole, causing the disc to rotate, which in turn causes the clamping blocks to move radially and clamp the long rod two. Subsequently, motor three is activated, and the worm gear drives the worm wheel to rotate, causing the long rod two to drive the circular plate one to rotate, pushing the long rod one and the flipping rod to retract radially, detaching them from the inner wall of the furnace. This allows for normal material discharge, preventing the flipping rod from obstructing normal discharge.

[0018] 2. The heating furnace for crude terbium fluoride production, through the set turning component, when heating and reaction are carried out, motor two is turned on, gear four drives gear three to rotate synchronously, the connecting cylinder drives the fixed cylinder and the turning rod to rotate synchronously, further turning the terbium oxide, and further improving the reaction and heating efficiency of terbium oxide.

[0028] A circular plate 90 is rotatably connected to the inner wall of a fixed cylinder 80. A connecting hole 91 is provided on the outer surface of the circular plate 90. A long rod 92 abuts against the inner wall of the connecting hole 91. The long rod 92 passes through a flipping rod 81 and is fixedly connected to the flipping rod 81.

The second long rod 93 is rotatably connected to the fixed cylinder 80 and the connecting cylinder 82. A worm gear 94 is rotatably connected to the left end of the second long rod 93. A stabilizer 95 is fixed to the left end of component 1. A worm gear 96 is rotatably connected to the inner side of the stabilizer 95. A motor 97 is fixed to the outer surface of the stabilizer 95. The output shaft of the motor 97 passes through the stabilizer 95 and is fixed to the outer surface of the worm gear 96. The worm gear 96 meshes with a worm wheel 94. A connecting piece 98 includes a cavity 980, which is located inside the worm wheel 94. A circular plate 981 is rotatably connected to the inner wall of the cavity 980. A connecting hole 982 is provided on the outer surface of the circular plate 981. A short rod 983 abuts against the inner wall of the connecting hole 982. The short rod 983 is away from the circular plate 981. One end of 981 is fixed with a clamping block 984.

After motor 4 989 is turned on, screw 988 rotates and drives T-shaped plate 986 to move towards fixed plate 987. At the same time, clamping block 984 moves towards long rod 2 93 and pushes short rod 983, so that short rod 983 contacts the inner wall of connecting hole 2 982, driving round plate 2 981 to rotate, which in turn drives short rod 983 and clamping block 984 to move radially, so that clamping block 984 passes through through hole 985 and clamps long rod 2 93. Then motor 3 97 is started, worm gear 96 drives worm wheel 94 and rotating rod 2 to rotate, round plate 1 90 rotates accordingly, and the inner wall of connecting hole 1 91 contacts long rod 1 92, pushing each long rod 1 92 and flipping rod 81 to retract radially away from the inner wall of furnace body 1. After cooling, open the cover 10, and the cylinder 7 extends to tilt the bottom plate 4 of the furnace body 1, so that terbium fluoride can be smoothly discharged from the right end, avoiding interference from the flipping rod 81.

[0029] The agitation assembly 8 includes a fixed cylinder 80, which is rotatably connected to the left end of the inner wall of the furnace body 1. A flipping rod 81 is provided inside the fixed cylinder 80, which passes through the fixed cylinder 80 and is slidably connected to the fixed cylinder 80. A connecting cylinder 82 is fixed to the left end of the fixed cylinder 80, which passes through the furnace body 1 and is rotatably connected to the furnace body 1. A gear 3 83 is fixed to the outer surface of the connecting cylinder 82. A gear 4 85 is rotatably connected to the left end of the furnace body 1. A motor 2 84 is fixed to the left end surface of the furnace body 1 through a mounting bracket. The output shaft of the motor 2 84 is fixed to the outer surface of the gear 4 85. The gear 4 85 meshes with the gear 3 83. When the motor 2 84 is turned on, the gear 4 85 drives the gear 3 83 to rotate synchronously. At this time, the connecting cylinder 82 drives the fixed cylinder 80 and the flipping rod 81 to rotate synchronously, further agitating the terbium oxide and further improving the reaction and heating efficiency of the terbium oxide.

[0030] Gear 13 is fixed to the outer surface of the left end of the furnace body 1. Motor 14 is fixed to the outer surface of the support frame 3 via a mounting bracket. Gear 25 is fixed to the output shaft of motor 14. Gear 25 is rotatably connected to the outer surface of the support frame 3 and meshes with gear 13. An exhaust port 12 is provided at the left end of the furnace body 1. A cover 10 is installed at the right end of the furnace body 1 via a flange. An air inlet 11 is provided on the outer surface of the cover 10. A base plate 4 is fixed to the bottom of the support frame 3. A support plate 5 is hinged to the bottom of the base plate 4. The furnace body 1 is fixed with a base 6 and two sets of support plates 5. The top of the set of support plates 5 away from the cover 10 abuts against the bottom of the base plate 4. A cylinder 7 is hinged to the top of the base 6 and the output end of the cylinder 7 is hinged to the bottom of the base plate 4. When the motor 14 is turned on, the gear 2 15 and gear 13 will rotate synchronously. At this time, the furnace body 1 will rotate synchronously, which will cause the terbium oxide to flip, improve heating and reaction uniformity. When discharge is required, the cylinder 7 extends, which will cause the base plate 4 to tilt the furnace body 1, so that the terbium fluoride can be discharged through the right end of the furnace body 1.

[0031] During processing, open the cover 10 and add terbium oxide into the furnace body 1. Close the cover 10, connect the exhaust pipe to the external gas purification device, and connect the inlet 11 to the hydrogen fluoride gas supply device to allow hydrogen fluoride to enter the furnace body 1. Turn on the resistance furnace 2 to heat the furnace body 1. At this time, turn on motor 14, which will drive gear 2 15 and gear 1 13 to rotate synchronously. The furnace body 1 will rotate synchronously, causing the terbium oxide to flip, improving heating and reaction uniformity. At the same time, turn on motor 2 84, and gear 4 85 will drive gear 3 83 to rotate synchronously. At this time, the connecting cylinder 82 will drive the fixed cylinder 80 and the turning rod 81 to rotate synchronously, further turning the terbium oxide and further improving the reaction and heating efficiency of the terbium oxide. Meanwhile, the long rod 2 93 rotates in the worm gear 94 and will not affect the position of the worm 96. When processing is completed and material needs to be discharged, turn on motor 4 989. At this time, the screw 988 will rotate, driving the T-shaped plate 986 to approach the fixed plate. When plate 987 moves, clamping block 984 moves synchronously closer to long rod 2 93. At this time, clamping block 984 drives short rod 983 to move synchronously. At this time, the surface of short rod 983 abuts against the inner wall of connecting hole 2 982, which causes round plate 2 981 to rotate. This causes each short rod 983 and clamping block 984 to move radially synchronously, allowing clamping block 984 to pass through through hole 985 and clamp long rod 2 93. At this time, motor 3 97 can be turned on normally, which causes worm gear 96 to drive worm wheel 94 to rotate synchronously. At this time, rotating rod 2 drives round plate 1 90 to rotate synchronously. At this time, the inner wall of connecting hole 1 91 abuts against the surface of long rod 1 92, which causes each long rod 1 92 and flipping rod 81 to move radially synchronously away from the inner wall of furnace body 1. At this time, wait for cooling and open cover 10. At this time, cylinder 7 extends, which causes bottom plate 4 to tilt furnace body 1, allowing terbium fluoride to be discharged through the right end of furnace body 1, avoiding the flipping rod 81 from affecting the normal discharge of terbium fluoride.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
