Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, and more specifically to an ethanol storage tank with a drying function. Background Art

[0002] The ethanol tank breathing valve mainly meets the ventilation requirements of the size of the tank and is installed on the top of the ethanol tank that stores Class A, B, and C liquids in conjunction with the flame arrester. The ethanol tank breathing valve is an important accessory to protect the safety of the tank. It is installed on the top plate of the ethanol tank and consists of a pressure valve and a vacuum valve. Its function is to maintain the airtightness of the ethanol tank under normal circumstances and reduce the evaporation loss of ethanol to a certain extent. When necessary, it can automatically ventilate and adjust the pressure inside and outside the ethanol tank to balance the pressure, which plays a safety role for the ethanol tank.

[0003] At present, in the actual use of the ethanol storage tank breathing valve, due to the need to balance the internal and external pressures of the ethanol storage tank, the opening and closing of the ethanol storage tank breathing valve needs to be adjusted more frequently. Moreover, since ethanol is a liquid structure under normal conditions, the commonly used ethanol storage tank breathing valve lacks a drying device. At this time, the air entering the ethanol storage tank may contain more moisture, and after the moisture and ethanol are miscible, the purity of the ethanol may change, thereby affecting the quality of the ethanol.

[0004] Therefore, in view of this, the existing structure is studied and improved, and an ethanol storage tank with a drying function is provided, in order to achieve a more practical purpose. Utility Model Content

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] In this scheme, when the ethanol breathing valve is used, when the ethanol storage tank needs to be supplemented with gas and used to balance the pressure, air is introduced from the breathing valve of the ethanol storage tank. Then, if the gas contains moisture, the anhydrous copper sulfate will turn blue when the gas passes through the anhydrous copper sulfate, and the moisture content of the air can be understood according to the degree of blueing. Then the gas passes through the drying box and is dried under the drying effect of the desiccant inside the drying box, and finally the gas entering the ethanol storage tank contains no moisture or contains less moisture, thereby reducing the degree of mutual solubility between moisture and ethanol, and further effectively reducing the influence of moisture in the air on the purity of ethanol. At the same time, the moisture content in the air can be detected according to the anhydrous copper sulfate, and the appropriate frequency of replacing the desiccant can be selected, and finally the quality of ethanol can be effectively guaranteed.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0038] Example:

[0039] See also Figure 1-4 , an ethanol storage tank with a drying function, comprising an ethanol storage tank 1, a breathing valve 2 is fixedly arranged at the top of the ethanol storage tank 1, a drying box 3 is fixedly arranged at the top of the ethanol storage tank 1 and close to the breathing valve 2, a No. 1 air guide pipe 4 is fixedly arranged on one side of the inner bottom of the drying box 3, and is connected with the ethanol storage tank 1 through the No. 1 air guide pipe 4, a No. 2 air guide pipe 5 is fixedly arranged at the other end of the drying box 3, and an anhydrous copper sulfate tempered glass cylinder 6 is fixedly installed between the No. 2 air guide pipe 5 and the breathing valve 2 through a flange;

[0040] Two parallel isolation plates 301 are fixedly arranged inside the drying box 3, a sealed load-bearing plate 302 is slidably connected between the two isolation plates 301, a plurality of spring members 303 are fixedly arranged between the bottom end of the sealed load-bearing plate 302 and the bottom of the drying box 3, a desiccant filling box 304 is arranged on the top of the sealed load-bearing plate 302, air ports 305 with isolation nets are provided at both ends of the bottom of the side of the desiccant filling box 304, a slide groove 306 is provided on the top of the drying box 3, and the desiccant filling box 304 is slidably connected to the slide groove 306;

[0041] A positioning hole 307 is fixedly opened on the side of the desiccant filling box 304 , and a locking bolt 308 is threadedly connected to the side of the drying box 3 .

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 Specifically, the height of the isolation plate 301 is 3 / 5 of the internal height of the ethanol storage tank 1 .

[0043] Specifically, the sealing load-bearing plate 302 includes a lower sealing plate 3021 and an upper sealing plate 3022 , and the height of the lower sealing plate 3021 is 1 / 2 of the internal height of the ethanol storage tank 1 .

[0044] Specifically, the upper sealing plate 3022 is an inverted T-shaped structure, and the upper sealing plate 3022 is engaged with the slide groove 306 after moving;

[0045] The width of the slide groove 306 is smaller than the width of the lower sealing plate 3021 .

[0046] By controlling the height of the isolation plate 301, the gas can only pass through the channel between the two isolation plates 301. Then, the height of the lower sealing plate 3021 is controlled. Since the spring member 303 is always in a compressed state, under the elastic effect of the spring member 303, when the lower sealing plate 3021 reaches the maximum height, the upper sealing plate 3022 is snapped into the slide groove 306 of the drying box 3. At this time, the channel between the two isolation plates 301 will be blocked, thereby preventing undried gas from passing through.

[0047] See also Figure 2 , Figure 3 and Figure 4 Specifically, a cover plate 3041 is slidably connected to the interior of the desiccant filling box 304 , and the cover plate 3041 includes an upper metal layer plate 3042 and a lower rubber sealing layer plate 3043 .

[0048] Specifically, a short air pipe 3044 with a valve is fixedly connected to the cover plate 3041 .

[0049] The cover plate 3041 can be used to ensure the sealing effect of the drying box 3. At this time, the metal layer plate 3042 ensures the stability of the cover plate 3041 when it moves, and the rubber sealing layer plate 3043 can ensure the sealing of the cover plate 3041 when it moves. When the cover plate 3041 moves, it is necessary to open the valve of the short air pipe 3044 with a valve to balance the air pressure above and below the cover plate 3041, thereby ensuring that the cover plate 3041 can move up and down smoothly.

[0050] See also Figure 3 and Figure 4 Specifically, a support column 3045 is fixedly provided inside the desiccant filling box 304, and the height of the support column 3045 is greater than the height of the air port 305 with the isolation net.

[0051] The height of the support column 3045 limits the maximum downward pressing height of the cover plate 3041 and can ensure that the filled desiccant can cover the air port 305 with the isolation net, so that the gas passing through the desiccant filling box 304 can be effectively dried.

[0052] Working principle:

[0053] When the entire device is in use, if the internal pressure in the ethanol storage tank 1 decreases, in order to balance the internal pressure of the ethanol storage tank 1, external air will be introduced at this time, specifically:

[0054] The valve port of the breathing valve 2 is opened. At this time, air enters from the breathing valve 2 and then enters the anhydrous copper sulfate tempered glass cylinder 6. Since anhydrous copper sulfate turns blue when it meets water, and the tempered glass structure allows the color change inside to be observed, at this time, the water content of the air can be determined according to the color change degree of the anhydrous copper sulfate, and the replacement frequency of the desiccant inside the desiccant filling box 304 can be determined according to the determination result;

[0055] The gas containing water enters the drying box 3 through the No. 2 gas duct 5, and then passes through the gap of the isolation plate 301, the gas port 305 with the isolation net and the desiccant filling box 304 in sequence, and is finally introduced into the ethanol storage tank 1 from the No. 1 gas duct 4. During this process, the desiccant inside the desiccant filling box 304 will fully absorb the moisture in the air to complete the drying of the gas.

[0056] When the desiccant needs to be replaced, the locking bolt 308 is unscrewed. At this time, under the action of the spring member 303, the height of the sealing load-bearing plate 302 is increased until the upper sealing plate 3022 is snapped into contact with the slide groove 306, so that the lower sealing plate 3021, the upper sealing plate 3022 and the isolation plate 301 can form a seal for the gas, thereby preventing the gas from passing through the desiccant filling box 304, and then, open the short air pipe 3044 with a valve to balance the internal and external pressures of the desiccant filling box 304, then, pull out the cover plate 3041, take out the desiccant in the desiccant filling box 304, and refill it with new desiccant, and then press down the desiccant filling box 304 again until the locking bolt 308 can be screwed into the positioning hole 307.

[0057] This completes the use of the entire device.

[0058] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
