Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical gas storage technology, specifically to a pharmaceutical gas storage device. Background Technology

[0002] In the pharmaceutical industry, the most commonly used gas storage equipment is the gas storage tank, which plays an important role in the entire pharmaceutical production process. In the cleanroom of drug production, a stable supply of compressed air is required to drive various pneumatic equipment, such as automatic filling production lines and pneumatic valves. The gas storage tank can ensure that a stable pressure gas source is still provided when the gas consumption of the equipment fluctuates. However, if the pressure control system of the air compressor malfunctions during the use of existing gas storage tanks, and the gas storage tank is continuously filled with air, the pressure inside the gas storage tank may exceed the design pressure, posing a safety hazard such as explosion.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a pharmaceutical gas storage device, including a gas storage tank 1, an expansion cylinder 2 inserted into the upper end of the gas storage tank 1, the inner wall of the gas storage tank 1 and the outer wall of the expansion cylinder 2 are sealed and fitted together, the inner cavity side wall of the gas storage tank 1 is connected to the inner cavity side wall of the expansion cylinder 2 through an elastic structure 3, an air inlet structure 4 is connected to the lower side wall of the gas storage tank 1, an air outlet pipe 5 is fixedly connected to the upper side wall of the gas storage tank 1, a liquid level monitoring structure 6 is installed at the lower inner cavity of the gas storage tank 1, a water collection tank 7 is fixedly installed at the lower end of the inner wall of the gas storage tank 1, and a solenoid valve 8 is fixedly connected to the lower end of the gas storage tank 1. The liquid level monitoring structure 6 is matched with the solenoid valve 8, and two support legs 10 are fixedly connected to the lower end of the gas storage tank 1 through a base plate 9. The two support legs 10 are symmetrically arranged.

[0016] The air storage tank 1 stores compressed air or other gases using its volume. When production equipment requires gas, the air storage tank 1 can stably supply gas, playing a role in buffering and stabilizing the gas supply pressure. If the pressure control system of the air compressor malfunctions and continues to fill the air storage tank, the pressure inside the air storage tank may exceed the design pressure, posing a safety hazard such as an explosion. In this case, the elastic structure 3 and the expansion cylinder 2 work together to increase the capacity of the air storage tank 1, thereby improving the buffering capacity of the air storage system and coping with pressure fluctuations during peak gas demand and equipment failures. The air intake structure 4 dries the gas before it enters the air storage tank 1, removing moisture, acidic gases, and other corrosive substances to prevent tank corrosion. The liquid level monitoring structure 6 and the solenoid valve 8 work together to establish a strict sewage discharge system, regularly discharging the oil-water mixture at the bottom of the air storage tank 1. The system automatically discharges sewage based on the liquid level, ensuring timely discharge. At the same time, the liquid level monitoring structure 6 can be adjusted to ensure a wide range of applicability of the equipment. The base plate 9 and the support legs 10 ensure the overall stability of the equipment. The water collection tank 7 facilitates the discharge of the oil-water mixture by the solenoid valve 8.

[0017] The elastic structure 3 includes a connecting plate 31 and a support plate 32. The connecting plate 31 is fixedly assembled to the inner cavity side wall of the expansion cylinder 2. The support plate 32 is fixedly assembled to the inner cavity side wall of the gas storage tank 1. The support plate 32 is located directly below the connecting plate 31. A sliding rod 33 is fixedly assembled to the lower end of the connecting plate 31. The sliding rod 33 is inserted through the support plate 32. A base 35 is fixedly assembled to the lower end of the sliding rod 33. A spring 34 is sleeved on the outer wall of the sliding rod 33. One end of the spring 34 is fixedly connected to the support plate 32, and the other end of the spring 34 is fixedly connected to the base 35.

[0018] When the pressure inside the gas tank 1 is too high, the pressure will push the expansion cylinder 2 upward. At this time, the expansion cylinder 2 drives the slide rod 33 to move through the connecting plate 31. The slide rod 33 moves longitudinally against the inner wall of the support plate 32, while driving the base 35 to compress the spring 34 and deform it. At the same time, the spring 34 stores force, expanding the usable space inside the gas tank 1 to facilitate the response to gas pressure fluctuations inside the tank. When the gas pressure returns to normal, the expansion cylinder 2 returns to its original position according to the elastic force of the spring 34. A sealing soft rubber is set between the expansion cylinder 2 and the gas tank 1, so that the expansion cylinder 2 has a certain damping when it moves.

[0019] The air intake structure 4 includes a screw cylinder 42, which is fixedly connected to the side wall of the air storage tank 1. An air intake pipe 41 is screwed onto the inner wall of the screw cylinder 42. A mesh cylinder 43 is fitted onto the inner end of the air intake pipe 41, and the inner wall of the mesh cylinder 43 is filled with desiccant.

[0020] The air compressor is connected through the air inlet pipe 41, and gas is input into the air storage tank 1. At the same time, the desiccant in the mesh cylinder 43 dries the gas, removing moisture, acidic gases and other corrosive substances to prevent corrosion of the tank. Meanwhile, the screw cylinder 42 is screwed to the air inlet pipe 41, which facilitates the disassembly and replacement of the air inlet pipe 41.

[0021] The liquid level monitoring structure 6 includes an L-shaped plate 61, which is fixedly mounted on the inner wall of the gas storage tank 1. An electric telescopic rod 62 is fixedly mounted on the upper end of the inner wall of the L-shaped plate 61. A slider 63 is fixedly mounted on the piston rod end of the electric telescopic rod 62. The slider 63 is slidably sleeved on the outer wall of the L-shaped plate 61. A liquid level sensor 64 is fixedly mounted on the lower end of the slider 63.

[0022] When the oil-water mixture accumulates to a certain level at the lower end of the inner cavity of the gas storage tank 1 and touches the liquid level sensor 64, the liquid level sensor 64 controls the solenoid valve 8 to open through the controller and discharge the oil-water mixture. As needed, the position of the slider 63 can be adjusted by the electric telescopic rod 62, and the longitudinal position of the liquid level sensor 64 can be adjusted at the same time to ensure the wide applicability of the equipment.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
