Technical Field

[0001] This utility model belongs to the field of production equipment technology, and in particular relates to an environmentally friendly and energy-saving ultra-clean high-purity sulfuric acid production equipment. Background Technology

[0002] High-purity sulfuric acid production equipment refers to a series of devices and facilities specifically designed for the preparation of high-purity sulfuric acid. High-purity sulfuric acid is widely used in industries such as semiconductors, electronics, and chemicals. Its production process involves multiple complex steps and technologies, including raw material processing, conversion, absorption, and purification. Therefore, while existing production equipment largely meets current needs, the following problems still exist.

[0003] In the production of high-purity sulfuric acid, operators may use a reaction vessel as the production reactor. During production, the operator adds raw materials to the reaction vessel to allow them to react. While the raw materials are reacting, a stirring device may be installed in the reaction vessel to enhance the reaction effect. However, during the reaction, some reactants may accumulate at the bottom of the reaction vessel, potentially preventing some materials from reacting. Therefore, we propose an environmentally friendly and energy-saving ultra-clean high-purity sulfuric acid production equipment. Utility Model Content

[0004] This utility model provides an environmentally friendly and energy-saving ultra-clean high-purity sulfuric acid production equipment. After the stirring blades rotate, they agitate the raw materials at the end of the reactor body, preventing the raw materials from accumulating at the end of the reactor body and improving the uniformity of the raw material reaction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly and energy-saving ultra-clean high-purity sulfuric acid production equipment, comprising a reaction vessel body and a stirring rod, wherein a stirring rod is installed in the middle of the reaction vessel body, a fixing frame is fitted on the surface of the stirring rod, and the fixing frame is slidably connected to the reaction vessel body, rotating rods are rotatably connected around the fixing frame, and several sets of stirring blades are fixed on the surface of each rotating rod, and a first gear is fixed on the side of each rotating rod near the stirring rod, and a second gear is meshed at the end of the first gear, and the second gear is installed on the stirring rod.

[0006] Furthermore, the inner wall of the reactor body is fixed with several sets of traction blocks, and the surface of the traction blocks is fitted with traction grooves fixed on the fixing frame, and a positioning rod passes through the middle of the traction groove, and the end of the positioning rod is fitted with an avoidance groove opened on the traction block.

[0007] The second gear is fixed with a collar sleeved on the surface of the stirring rod through one side, and a bolt passes through the middle of the collar and the stirring rod, with a nut threaded onto the end of the bolt.

[0008] Furthermore, the bolt surface is symmetrically fitted with extension sleeves, and the extension sleeves are all fixed on the outer wall of the collar, and the ends of the extension sleeves are all set as planes.

[0011] Furthermore, rotating blocks are symmetrically fixed at both ends of the rotating rod, and the surfaces of the rotating blocks are all fitted with rotating grooves opened on the fixing frame.

[0012] The beneficial effects of this utility model are:

[0013] 1. This environmentally friendly and energy-saving ultra-clean high-purity sulfuric acid production equipment is equipped with a first gear, a rotating rod, a stirring blade, and a second gear. After the stirring rod rotates, it drives the first gear to rotate through the second gear. When the first gear rotates, it drives the rotating rod to rotate, which in turn drives the stirring blade to rotate. When the stirring blade rotates, it stirs the raw materials deposited at the bottom of the reactor body, preventing the raw materials from accumulating at the bottom of the reactor body and improving the uniformity of the raw material reaction.

[0014] 2. This environmentally friendly and energy-saving ultra-clean high-purity sulfuric acid production equipment is equipped with a traction block, a traction groove, a positioning rod, and a clearance groove. When the operator pulls the positioning rod, the positioning rod moves out of the clearance groove. Then, the operator pulls the fixed frame, which causes the traction groove to slide on the surface of the traction block. This allows the fixed frame to move within the inner wall of the reactor body, making it convenient for the operator to change the position of the fixed frame according to usage needs and increasing the scope of use of the fixed frame.

[0025] To further understand the utility model's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0026] Example:

[0027] Please see Figure 1 - Figure 8An environmentally friendly and energy-saving ultra-clean high-purity sulfuric acid production equipment includes a reactor body 1 and a stirring rod 2. The stirring rod 2 is installed in the middle of the reactor body 1. A fixing frame 3 is fitted onto the surface of the stirring rod 2, and the fixing frame 3 is slidably connected to the reactor body 1. Rotating rods 6 are rotatably connected around the fixing frame 3. Rotating blocks 12 are symmetrically fixed at both ends of the rotating rods 6, and rotating grooves 13 formed on the fixing frame 3 are fitted onto the surface of each rotating block 12. Several sets of stirring blades 4 are fixed to the surface of each rotating rod 6. A first gear 5 is fixed to the side of each rotating rod 6 near the stirring rod 2, and a second gear 7 meshes with the end of the first gear 5. The second gear 7 is installed on the stirring rod 2. During the production of high-purity sulfuric acid, the operator adds raw materials into the reactor body 1, and the raw materials react... The reaction takes place inside the reactor body 1. During the reaction, the operator starts the motor, which drives the stirring rod 2 to rotate. The stirring rod 2 stirs the raw materials inside the reactor body 1. When the stirring rod 2 rotates, it drives the second gear 7 to rotate. When the second gear 7 rotates, it drives the first gear 5 to rotate. When the first gear 5 rotates, it drives the rotating rod 6 to rotate within the fixed frame 3. When the rotating rod 6 rotates, it drives the stirring blade 4 to rotate. When the stirring blade 4 rotates, it stirs the raw materials deposited at the bottom of the reactor body 1, preventing the raw materials from accumulating at the bottom of the reactor body 1 and thus ensuring that the raw materials are not fully stirred.

[0028] In other embodiments, a plurality of traction blocks 14 are fixed to the inner wall of the reactor body 1, and traction grooves 15 fixed to the fixing frame 3 are sleeved on the surface of the traction blocks 14. A positioning rod 19 passes through the middle of the traction groove 15, and an avoidance groove 16 is sleeved on the end of the positioning rod 19. A guide sleeve 17 is sleeved on the surface of the positioning rod 19, and the guide sleeve 17 is fixed on the outer wall of the traction groove 15. A slider 18 is fixed inside the guide sleeve 17, and a sliding groove 20 is sleeved on the surface of the slider 18. When the operator needs to adjust the height of the fixing frame 3, the operator first pulls the positioning rod 19. The positioning rod 19 slides in the guide sleeve 17, and when the positioning rod 19 slides in the guide sleeve 17, the positioning rod 19 drives the sliding groove 20 to slide in the slider 18. When the groove 20 slides within the slider 18, the positioning rod 19 cannot detach from the guide sleeve 17. When the operator pulls the positioning rod 19 into the guide sleeve 17, the positioning rod 19 moves out of the clearance groove 16, so that the positioning rod 19 and the clearance groove 16 no longer fix the traction block 14 and the traction groove 15. Then, the operator pulls the fixing frame 3, and the fixing frame 3 drives the traction groove 15 to slide on the surface of the traction block 14, so that the fixing frame 3 can move up and down within the reactor body 1. When the fixing frame 3 moves to the appropriate position, the operator takes the positioning rod 19 and inserts it into another clearance groove 16 opened on the surface of the traction block 14, fixing the positioning rod 19 and the clearance groove 16 again to fix the traction block 14 and the traction groove 15, thus fixing the position of the fixing frame 3, making it convenient for the operator to adjust the position of the fixing frame 3.

[0029] The second gear 7 is fixed with a collar 10 on the surface of the stirring rod 2 through one side. A bolt 9 passes through the middle of both the collar 10 and the stirring rod 2. Both sides of the stirring rod 2 through which the bolt 9 passes have oblong holes, which match the cylindrical shape of the bolt 9. A nut 11 is threaded onto the end of the bolt 9. Extending sleeves 8 are symmetrically fitted onto the surface of the bolt 9, and each extending sleeve 8 is fixed to the outer wall of the collar 10. The ends of the extending sleeves 8 are all flat. When the position of the fixing bracket 3 is adjusted, the first gear 5 and the second gear... After separation, the position of the second gear 7 needs to be adjusted. When adjusting the position of the second gear 7, the operator turns the nut 11 so that the nut 11 and the bolt 9 are threaded together. After the bolt 9 and the nut 11 no longer clamp the collar 10 on the surface of the stirring rod 2, the operator pulls the second gear 7 to move. The second gear 7 drives the collar 10 to slide on the surface of the stirring rod 2. When the collar 10 moves, the collar 10 drives the bolt 9 to slide in the waist-shaped hole opened on the stirring rod 2, so that the second gear 7 can move with the first gear 5.
