Description

Technical Field

[0001] The utility model relates to the technical field of electronic-grade hydrofluoric acid production, and more specifically to an ultra-clean high-purity electronic-grade hydrofluoric acid concentration ratio regulating device. Background Art

[0002] Ultra-clean high-purity electronic-grade hydrofluoric acid is an aqueous solution of hydrogen fluoride gas. It is a clear, colorless, fuming, corrosive liquid with a strong pungent odor. During the production of ultra-clean high-purity electronic-grade hydrofluoric acid, its concentration needs to be adjusted through an adjusting device to ensure the quality of the product.

The water supply device includes a static pressure water tank, an electromagnetic reversing valve, and a water outlet flow meter. A differential pressure reducing valve and a throttle valve are arranged between the static pressure water tank and the electromagnetic reversing valve in sequence. The static pressure water tank is connected to the differential pressure reducing valve, the throttle valve, the electromagnetic reversing valve and the water outlet flow meter in sequence through a water pipe. The mixing device includes a turbine flow meter, an electric stirrer, a mixer, and a concentration ratio detection device for detecting the concentration of hydrofluoric acid in the mixer. The blade end of the electric stirrer is arranged in the mixer, and the turbine flowmeter is connected to the water outlet flowmeter and the mixer respectively; it mainly realizes the automatic proportioning of the hydrofluoric acid concentration by utilizing the PLC control technology. The system is not only simple in structure, convenient in maintenance and low in cost, but also can realize the online detection of the hydrofluoric acid concentration. The PLC control box arranged in the hydrofluoric acid proportioning device is a control device integrating display, alarm and transmission. The liquid crystal display screen on the control box panel can intuitively display the real-time value of the hydrofluoric acid concentration. The hydrofluoric acid proportioning device utilizes the fixed ratio proportioning technology of variable frequency pump control and flow feedback to ensure the stability and reliability of the proportioning concentration and has good environmental adaptability.

[0004] The above-mentioned ultra-clean high-purity electronic-grade hydrofluoric acid concentration ratio regulating device still has certain shortcomings: since the regulating device does not have a lifting function, once the height of the regulating device is set lower than the height of the solution, it will affect the operation of the regulating device, thereby reducing the working efficiency of the device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an ultra-clean high-purity electronic-grade hydrofluoric acid concentration ratio adjustment device to solve the problems existing in the prior art.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an ultra-clean high-purity electronic-grade hydrofluoric acid concentration ratio adjustment device, comprising a solution containing cylinder, the surface of the solution containing cylinder is symmetrically inlaid with two connecting nuts along the center, the surface of the solution containing cylinder is detachably installed with a lifting component through the connecting nuts, the interior of the lifting component is fixedly connected with a fastening connection component, the interior of the fastening connection component is provided with an adjustment cylinder, the interior of the adjustment cylinder is provided with a sealing gasket, the top end of the sealing gasket is fixedly connected with a connecting rod, and the middle part of the lower surface of the adjustment cylinder is connected with a connecting pipe.

[0007] The fastening connection assembly includes a second mounting ring and connecting through holes, and the surface of the second mounting ring is provided with four connecting through holes in a circular array.

[0008] Wherein, the surface of the second mounting ring is connected to a hydraulic telescopic rod through the connecting through hole, and one end of the hydraulic telescopic rod is fixedly connected to an arc-shaped mounting plate.

[0009] The side wall of the arc-shaped mounting plate is fixedly connected with three suction cups in an arc-shaped array, and the surface of the suction cup fits with the surface of the adjustment cylinder.

[0010] Wherein, the lifting assembly includes an L-shaped connecting plate and a connecting bolt, and the bottom end of the side wall of the L-shaped connecting plate is detachably mounted with a connecting bolt, and one end of the connecting bolt is connected to the inside of the connecting nut.

[0011] Among them, a hydraulic lifting rod is detachably installed on one side of the lower surface of the L-shaped connecting plate, and a stabilizing plate is fixedly connected to the bottom end of the hydraulic lifting rod.

[0012] Among them, one end of the stabilizing plate is fixedly connected to a first mounting ring, the inner wall of the first mounting ring is connected to the other end of the hydraulic telescopic rod, and the number of the stabilizing plates is two.

[0013] The beneficial effects of the above technical solution of the utility model are as follows:

[0014] 1. In the above scheme, the ultra-clean high-purity electronic-grade hydrofluoric acid concentration ratio adjustment device is provided with a fastening connection component. When the model of the adjustment cylinder is smaller than the model that can be fixed by the lifting component, the adjustment cylinder is placed inside the fastening connection component, and then the four sets of hydraulic telescopic rods are started to drive the arc-shaped mounting plate to extend and retract until the surface of the suction cup is closely fitted with the surface of the adjustment cylinder.

Because the hydraulic telescopic rod has the function of automatic extension and retraction, it can control the size of the area surrounded by the four sets of arc-shaped mounting plates, thereby adapting to various types of adjustment cylinders and enhancing the adaptability of the device;

[0015] 2. In the above scheme, the ultra-clean high-purity electronic-grade hydrofluoric acid concentration ratio adjusting device is provided with a lifting component. When the height of the adjusting cylinder is set lower than the height of the solution inside the solution holding cylinder, the hydraulic lifting rod inside the lifting component is started to make it lift and lower. Then the hydraulic lifting rod will drive the stabilizing plate and the first mounting ring to move downward. Because the adjusting cylinder is connected to the first mounting ring through a fastening connecting component, the movement of the first mounting ring can drive the movement of the adjusting cylinder until the connecting pipe is lowered into the solution, so as to adjust the concentration of the hydrofluoric acid solution. Because the hydraulic lifting rod has the function of automatic lifting, the position of the adjusting cylinder can be adjusted, thereby facilitating the operation of the adjusting device and improving the working efficiency of the device.

[0025] The fastening connection assembly 3 includes a second mounting ring 31 and a connecting through hole 32. The surface of the second mounting ring 31 is provided with four connecting through holes 32 in a circular array. The surface of the second mounting ring 31 is connected to a hydraulic telescopic rod 33 through the connecting through holes 32. One end of the hydraulic telescopic rod 33 is fixedly connected to an arc-shaped mounting plate 34. The side wall of the arc-shaped mounting plate 34 is fixedly connected to three suction cups 35 in an arc-shaped array. The surface of the suction cup 35 fits the surface of the adjusting cylinder 4. The lifting assembly 2 includes an L-shaped connecting plate 21 and a connecting bolt 22. The bottom end of the side wall of the L-shaped connecting plate 21 is detachably mounted with a connecting bolt 22. One end of the connecting bolt 22 is connected to the inside of the connecting nut. A hydraulic lifting rod 23 is detachably mounted on one side of the lower surface of the L-shaped connecting plate 21. The bottom end of the hydraulic lifting rod 23 is fixedly connected to a stabilizing plate 24. One end of the stabilizing plate 24 is fixedly connected to a first mounting ring 25. The inner wall of the first mounting ring 25 is connected to the other end of the hydraulic telescopic rod 33. There are two stabilizing plates 24.

[0026] Benefits: By symmetrically inlaying two connecting nuts on the surface of the solution containing cylinder 1 along the center, the connecting nuts and the connecting bolts 22 cooperate with each other, so as to achieve the effect of detachable lifting assembly 2.

[0027] The working process of the utility model is as follows:

[0028] When the ultra-clean high-purity electronic-grade hydrofluoric acid concentration ratio adjustment device is in use, in order to enhance the adaptability of the device, a fastening connection component 3 is provided.
