Description

Technical Field

[0001] The utility model relates to the technical field of hydrofluoric acid production, in particular to a hydrofluoric acid filling machine. Background Technique

[0002] Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas, a clear, colorless, fuming corrosive liquid with a strong pungent odor. Melting point -83.3 °C, boiling point 19.54 °C, flash point 112.2 °C, density 1.15 g / cm3. It is easily soluble in water and ethanol, slightly soluble in ether. Because the binding ability between hydrogen atoms and fluorine atoms is relatively strong, and there are hydrogen bonds between hydrogen fluoride molecules in the aqueous solution, hydrofluoric acid cannot be completely ionized in water. Therefore, theoretically, low-concentration hydrofluoric acid is a weak acid. It has extremely strong corrosiveness and can strongly corrode metals, glass and silicon-containing objects. If inhaled or contacted with the skin, it will cause incurable burns. In the laboratory, it is generally prepared from fluorite (mainly calcium fluoride) and concentrated sulfuric acid, and needs to be sealed in a plastic bottle and stored in a cool place.

[0003] For example, the patent document with the publication number CN218114996U discloses a hydrofluoric acid filling machine. The sealing measure of this filling machine is to press the gasket on the mouth of the receiving bottle. This sealing method is prone to poor sealing due to pressure changes, resulting in air leakage. Content of the Utility Model

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] As Figure 1 - Figure 4 shown, a hydrofluoric acid filling machine includes an equipment platform 100. A transportation device 300 is installed on the upper surface of the equipment platform 100. A storage tank 200 is provided on one side of the transportation device 300. The storage tank 200 is fixedly connected to the equipment platform 100. A receiving mechanism is installed on the transportation device 300. A sealing mechanism is provided above the receiving mechanism. A filling mechanism is provided above the sealing mechanism. The sealing mechanism includes a rigid filling tube 502. The bottom end of the rigid filling tube 502 is fixedly connected to an elastic sealing tube 501. A sealing ring 503 is provided on the outside of the elastic sealing tube 501. Radial sliding columns 504 distributed in a circumferential array are slidably connected to the sealing ring 503. The inner ends of the radial sliding columns 504 are fixedly connected to a sealing arc plate 505. An inclined surface is provided on the outside of the radial sliding columns 504. An outer ring 506 is slidably connected to the outside of the sealing ring 503. An inclined platform 507 is fixedly connected to the inside of the outer ring 506. The inclined surface of the radial sliding column 504 is slidably connected to the inclined platform 507. An electric telescopic rod 508 is fixedly connected to the top end of the outer ring 506. The electric telescopic rod 508 and the top end of the sealing ring 503 are connected to the filling mechanism.

[0025] The rigid filling pipe 502 is used to install the elastic sealing pipe 501. The sealing arc plate 505 is used to cover the mouth of the receiving bottle 402. The sealing ring 503 is used to slidably connect the radial sliding column 504. The radial sliding column 504 is used to install the sealing arc plate 505. The sealing arc plate 505 squeezes the elastic sealing pipe 501 along the sliding direction of the radial sliding column 504, so that the elastic sealing pipe 501 has a better sealing effect on the mouth of the receiving bottle 402. The electric telescopic rod 508 pushes the outer ring 506 to descend, the outer ring 506 drives the inclined platform 507 to descend, and the inclined surface of the inclined platform 507 squeezes the inclined surface of the radial sliding column 504, causing the radial sliding column 504 to move towards the center along the diameter direction.

[0026] The material receiving mechanism includes a disc 401. The upper surface of the disc 401 is provided with clamping components distributed in a circumferential array. A reset component is arranged outside the clamping components, and a receiving bottle 402 is clamped inside the clamping components.

[0027] The disc 401 is used to install the clamping components and the reset component. The receiving bottle 402 is used to collect the filled hydrofluoric acid.

[0028] The clamping component includes a V-shaped rod 403. The bent part of the V-shaped rod 403 is hinged to the disc 401, and a connecting rod 404 is hinged to the top of the V-shaped rod 403.

[0029] The receiving bottle 402 presses down on the inner end of the V-shaped rod 403, and the outer end of the V-shaped rod 403 moves towards the body of the receiving bottle 402, causing the V-shaped rod 403 to clamp the receiving bottle 402. The connecting rod 404 is used to connect the sliding sleeve 405, facilitating the direct placement of the receiving bottle 402.

[0030] The reset component includes a sliding sleeve 405. The sliding sleeve 405 is hinged to the top of the connecting rod 404. The sliding sleeve 405 is slidably connected to a reset sliding column 406. The bottom end of the reset sliding column 406 is fixedly connected to the disc 401. A spring 407 is arranged outside the reset sliding column 406. The two ends of the spring 407 are respectively fixedly connected to the sliding sleeve 405 and the disc 401.

[0031] After the receiving bottle 402 is placed, the V-shaped rod 403 completes the clamping. The sliding sleeve 405 is pulled downwards through the connecting rod 404, the spring 407 is compressed, and the reset sliding column 406 provides a sliding track. After the receiving bottle 402 is taken out, the elastic potential energy of the receiving bottle 402 is released, pushing the sliding sleeve 405 to move upwards, causing the top of the V-shaped rod 403 to move away, facilitating the next placement.

[0032] The filling mechanism includes two extension plates 601, which are fixedly connected to the left and right sides of the rigid filling pipe 502. A hydraulic cylinder 602 is fixedly connected to one of the extension plates 601. The bottom end of the hydraulic cylinder 602 is fixedly connected to the equipment platform 100. The other extension plate 601 is slidably connected to a vertical sliding column 603. The bottom end of the vertical sliding column 603 is fixedly connected to the vertical sliding column 603. The top end of the electric telescopic rod 508 and the top end of the sealing ring 503 are fixedly connected to the extension plate 601.

[0033] The hydraulic cylinder 602 controls the up and down movement of one side extension plate 601 through its own expansion and contraction, so that the rigid filling pipe 502 also moves accordingly. The vertical sliding column 603 is used to maintain the stability of the rigid filling pipe 502 during movement.

[0034] The filling mechanism further includes a flexible hose 604. The two ends of the flexible hose 604 are respectively fixedly connected to the tank mouth of the storage tank 200 and the top end of the rigid filling pipe 502. A pump body 605 is connected in series in the middle of the rigid filling pipe 502.

[0035] The pump body 605 is used to pump hydrofluoric acid, and the flexible hose 604 is used to connect the storage tank 200 and the rigid filling pipe 502.

[0036] Working principle:

[0037] Put the receiving bottle 402 into the clamping assembly. The receiving bottle 402 presses the inner end of the V-shaped rod 403, and the outer end of the V-shaped rod 403 presses the receiving bottle 402 tightly, so that the receiving bottle 402 is stably conveyed on the conveying device 300.

[0038] When the receiving bottle 402 is conveyed to the directly lower side of the sealing mechanism, start the hydraulic cylinder 602. The hydraulic cylinder 602 pushes the extension plate 601 and the rigid filling pipe 502 downward, sleeving the elastic sealing pipe 501 on the bottle mouth of the receiving bottle 402. Then start the electric telescopic rod 508. The electric telescopic rod 508 pushes the outer ring 506 downward, and then the inclined table 507 descends, and gradually starts to squeeze the radial sliding column 504, so that the radial sliding column 504 moves close to the center of the circle, making the sealing arc plate 505 clamp the elastic sealing pipe 501, so that the elastic sealing pipe 501 forms a good seal on the bottle mouth of the receiving bottle 402. Finally, turn on the pump body 605 to pump the hydrofluoric acid in the storage tank 200 into the receiving bottle 402 to complete the filling operation.
