Description

Technical Field

[0001] This invention relates to the technical field of air compressor storage tanks, and more particularly to a heat preservation device for air storage tanks. Background Technology

[0002] Pneumatic actuators are widely used in many industries and enterprises. However, due to air compressor malfunctions or other reasons, the quality of the instrument air source may be poor, containing significant amounts of water. This water can freeze in the air source pipeline and inside the actuator, causing the actuator to fail to operate and affecting the safe and stable operation of the system and production. It also causes wear and corrosion of internal actuator components, reducing equipment lifespan and increasing maintenance costs. To improve air source quality, air tanks are typically used to separate and remove moisture from the instrument air. However, in low ambient temperatures, if water accumulates in the air tank for a long time without timely drainage, it can also freeze. This is especially true in northern regions, where extreme cold weather has frequently occurred in recent years, with ambient temperatures dropping to below -20 degrees Celsius, further increasing the risk of air source system freezing.

[0003] The present invention aims to develop a heat preservation device for a gas storage tank. The device improves and maintains the ambient temperature of the gas storage tank through a temperature control component, preventing the gas source from freezing directly due to water. By adding an automatic timed drainage solenoid valve, accumulated water is removed in time, improving the quality of the stored gas, providing a reliable working medium for the actuator, ensuring the normal operation of the actuator, and laying a solid foundation for stable production operation.

In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0029] Example 1 Reference Figure 1 The first embodiment of the present invention provides a heat preservation device for a gas storage tank, the device comprising, The self-temperature controlled insulation box includes a box body 101, a cabinet door 102 fixedly connected to the box body 101 by a hinge, a base 103 fixedly connected inside the box body 101, and a gas storage tank 104 installed above the base 103. The box 101 is a double-layer design with insulation cotton in between. The box is made of high-quality steel with a thickness of 2-2.5mm. The size is designed according to the size of the gas tank to ensure that the gas tank is placed effectively and leave space for inspection and maintenance. The bottom of the box 101 is provided with a drain outlet, and the bottom of the base 103 is also provided with a drain outlet of the same size and concentric axis.

[0030] Furthermore, the enclosure 101 includes an air inlet 101a on the surface of the enclosure 101, an air outlet on the other side of the enclosure 101, a safety valve outlet 101c on the outer surface of the enclosure 101, a drain outlet at the bottom of the enclosure 101, a rain cover 101e on the top of the enclosure 101, a sealing strip 101f on the edge of the enclosure 101, and a clip fixedly installed inside the enclosure 101. Among them, the sealing strip 101f needs to have a good sealing effect, and the material should preferably be EPDM.

[0031] Furthermore, the cabinet door 102 includes a pressure gauge observation window 102a opened on the cabinet door 102, a power switch 102b disposed on the outer surface of the cabinet door 102, a temperature controller 102c installed on the outer surface of the cabinet door 102, and a door lock 102d disposed on the cabinet door 102.

[0032] Preferably, the cabinet 101 has a lock groove, which can be inserted into the lock groove by squeezing the sealing strip 101f with the cabinet door 102 and then rotating the door lock 102d, thus achieving a better sealing and heat preservation effect.

[0033] More preferably, the gas storage tank 104 includes a tank body 104a mounted and fixed on the base 103, a pressure gauge 104b disposed on the surface of the tank body 104a, a safety valve 104c fixedly connected to the top of the tank body 104a, a safety valve exhaust pipe 104d extending from one end of the safety valve 104c, an exhaust pipe 104e adapted to be installed on the surface of the tank body 104a, an intake pipe 104f adapted to be installed on the surface of the tank body 104a, and a solenoid valve 104g disposed at the bottom of the tank body 104a. Among them, the solenoid valve 104g can be set to drain water at a time, so that the water in the gas storage tank 104 is discharged at a time.

[0034] Furthermore, the base 103 includes a water inlet 103a that is installed through the surface of the base 103, and a manual drain valve 103b that is provided on the surface of the base 103.

[0035] During use, the gas tank 104a is installed inside the housing 101. The safety valve exhaust pipe is then connected to the gas tank 104a through the safety valve outlet. The exhaust pipe 104e is then installed to the gas tank 104a through the exhaust port. The inlet pipe 104f is then installed to the gas tank 104a through the inlet port. The cabinet door 102 is then closed by turning the door lock. The cabinet door 102, which is fixed by the hinge, presses the sealing strip 101f on the surface of the housing 101, thus sealing the inside of the housing 101 and achieving a good heat preservation effect. The pressure gauge display and the overall condition inside the housing 101 can be observed through the pressure gauge observation window 102. The water in the gas tank 104a can be discharged into the base 103 at regular intervals through the solenoid valve 104g.

[0036] In summary, the sealing strip 101f improves the overall sealing effect of the housing 101, enhances the internal insulation effect, and allows for observation of the pressure gauge reading and the overall condition inside the housing 101 through the pressure gauge observation window 102. Furthermore, the solenoid valve 104g can periodically drain the water in the gas storage tank 104 into the base 103, effectively solving the problem of easy freezing of the gas storage device in cold environments and improving the quality of the gas source.

[0037] Example 2 Reference Figure 1 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a temperature control component 200, including a heating rod 201 that is adapted to be installed inside the base 103, and a water pump unit component 202 that is fixedly installed inside the base 103.

[0038] Furthermore, the water pump unit component 202 includes a protective cover 202a fixedly installed inside the base 103, a water pump 202b disposed inside the protective cover 202a, an inlet pipe 202c disposed on one side of the water pump 202b and penetrating the protective cover 202a, an outlet pipe 202d fixedly connected to one side of the water pump 202b and penetrating the protective cover 202a, and a return pipe 202e disposed through the base 103; The power switch 102b is connected to the water pump 202b, the temperature controller 102c is connected to the heating rod 201, the water inlet pipe 202c is coiled in a ring inside the housing 101 and fixedly installed on the housing 101 by the provided clips, the joints of the water inlet pipe 202c and the water outlet pipe 202d that pass through the protective cover 202a, and the joints of the return pipe 202e that pass through the base 103 are all sealed with sealant to prevent water leakage.

[0039] Among them, the water outlet pipe 202d is made of a heat-conducting material, preferably copper.

[0040] In use, water is injected into the temperature control component 200 through the water inlet 103a. At this time, the power switch 102b is pressed to start the water pump unit 202. The heating rod 201 heats the water. The temperature controller 102c can control the temperature adjustment of the heating rod 201. The water pump draws water in through the inlet pipe 202c, discharges water through the outlet pipe 202d, and finally recovers water through the return pipe 202e. The water is also cooled through the outlet pipe 202d, maintaining the temperature inside the chamber 101 in an optimal working environment of 15°~25°.

[0041] In summary, by adjusting the temperature controller 102c, the temperature inside the housing 101 can be precisely controlled, effectively improving the working environment of the gas storage tank 104.

[0042] Example 3 Reference Figure 1 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an automatic replenishment and drainage assembly 300, including a drainage component adapted to be installed inside the base 103, and an adjustment component disposed inside the base 103.

[0043] Furthermore, the drainage component includes a positioning slide rod 301a fixedly installed inside the base 103, a float plate 301b slidably connected to the positioning slide rod 301a, a connecting rod 301c fixedly connected to the outer surface of the float plate 301b, a guide rod 301d movably connected inside the float plate 301b, and a valve 301e extending from one end of the guide rod 301d.

[0044] Furthermore, by rotating the manual drain valve 103b into the drainage component and lifting the manual drain valve 103b directly, the valve 301e can be opened directly to drain the water inside.

[0045] More preferably, the adjusting components include a partition plate 302a fixedly connected inside the base 103, a water inlet groove 302a-1 opened on the partition plate 302a, a sliding groove 302a-2 opened inside the partition plate 302a, a limiting guide groove 302a-3 opened on one side of the partition plate 302a, a guide tube 302b set on one side of the partition plate 302a, a pull rope 302b-1 installed in the guide tube 302b, a float 302b-2 fixedly connected to one end of the pull rope 302b-1, a first baffle 302c slidably connected inside the sliding groove 302a-2, a spring 302d fixedly connected to the first baffle 302c inside the sliding groove 302a-2, and a second baffle 302e slidably connected inside the sliding groove 302a-2. Among them, the float 301b can drive the guide rod 301d to open the valve 301e, and can also drive the second baffle 302e to open at the same time. The other end of the pull rope 302b-1 is fixedly connected to the first baffle 302c. When the float ball 302b-2 floats, the first baffle 302c can be pulled down by the pull rope 302b-1. The connecting rod 301c passes through the limiting guide groove 302a-3 and is fixedly connected to the second baffle 302e.

[0046] In use, when the water inlet 103a touches the float 302b-2, the float 302b-2 floats up, causing the pull rope 302b-1 to pull down the first baffle 302c, closing the water inlet tank. When the water evaporation inside the temperature control component 200 decreases, the float 302b-2 will move downwards. At this time, the spring 302d will pull the first baffle 302c back to its original position, opening the water inlet tank. When water is periodically discharged into the base 103 through the solenoid valve 104g, when the water touches the float 301b, the float 301b will rise, causing the second baffle 302e, which is connected to it via the connecting rod 301c, to move upwards, opening the water inlet tank 302a-1, and the water will... Water is preferentially supplied to the temperature control component 200 through the inlet tank 302a-1. When the water inside the temperature control component 200 is replenished, the float ball 302b-2 will rise and pull down the first baffle 302c, closing the inlet tank 302a-1. If the water inside the temperature control component 200 is in a normal state, the first baffle 302c will not open. When the solenoid valve 104g continues to drain water, the float plate 301b will drive the guide rod 301d to open the bottom valve 301e, allowing the water inside to drain. At this time, the water inside will not be completely drained, so that less water is needed to replenish the temperature control component 200 next time.

[0047] Among them, the buoyancy of float 302b-2 is F1, the tension of spring 302d is L1, the buoyancy of float plate 301b is F2, and the suction force of valve drainage is X1. When the water in temperature control component 200 is sufficient, F1 > L1, and vice versa when it is insufficient. When the water in the regulating component is sufficient to make float plate 301b float, F2 is greater than X1, and vice versa.

[0048] In summary, the design of the automatic water supply and drainage component 300 allows the water discharged periodically by the solenoid valve 104g to be appropriately replenished into the temperature control component 200. After replenishment, excess water can be discharged through the valve 301e, achieving the functions of automatically replenishing the water in the temperature control component 200 and automatically draining excess water from the base 103. This greatly reduces workload, improves work efficiency, and enables the gas storage tank to operate continuously under normal working conditions.
