Description

Technical Field

[0001] This utility model belongs to the field of ethylene glycol storage, specifically an ethylene glycol storage device with moisture-proof function. Background Technology

[0002] Ethylene glycol is a colorless, odorless, sweet-tasting viscous liquid. It is the simplest diol and an important basic chemical raw material with a wide range of applications. Its core uses are concentrated in the following categories: automotive antifreeze, polyester synthesis, chemical intermediates and solvents. Industrially, it is mainly produced by the hydration of ethylene oxide, that is, the oxidation of ethylene to produce ethylene oxide, which then reacts with water in the presence of a catalyst to produce ethylene glycol.

[0003] A search revealed a Chinese patent (authorization announcement number CN209321544U) disclosing a storage tank for facilitating the transportation of water-ethylene glycol fire-resistant hydraulic fluid. This patented technology includes a lower baffle and a second screw cap. The lower baffle has a first limiting groove at its bottom and a first fixing groove at its top. The first fixing groove connects to the bottom of a spring, and the spring contains a telescopic connecting rod. The bottom of the telescopic connecting rod connects to the bottom of the first fixing groove. The tops of both the spring and the telescopic connecting rod connect to the bottom of a second fixing groove, which is located at the bottom of an upper baffle. The bottom of the upper baffle has a limiting element positioned between the second fixing grooves. This storage tank for facilitating the transportation of water-ethylene glycol fire-resistant hydraulic fluid, equipped with a first limiting groove, a spring, a telescopic connecting rod, a forklift slot, and a storage tank body, facilitates the orderly stacking and storage of the storage tank body, as well as its fixation and transportation. It also provides some shock absorption protection, making it more convenient and safer to use.

[0004] After ethylene glycol is produced, it is usually stored in storage tanks. However, existing storage tanks do not have moisture-proof functions. If the moisture inside the storage tank is too high, the ethylene glycol will absorb water, causing the water content of the ethylene glycol to increase, the purity to decrease, and the quality to fail to meet standards. Moreover, if the storage tank is placed in a humid environment, the moisture around the storage tank will be too high, and when ethylene glycol is added to the storage tank, the moisture will easily enter the storage tank along with the ethylene glycol. Therefore, this utility model provides an ethylene glycol storage device with moisture-proof function. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problems of existing storage tanks lacking moisture-proof function, excessive moisture inside the storage tank causing ethylene glycol to absorb water, increasing its water content, reducing its purity, and failing to meet quality standards, and the fact that excessive moisture around the storage tank can easily enter the storage tank when ethylene glycol is added, this utility model proposes an ethylene glycol storage device with moisture-proof function.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The ethylene glycol storage device with moisture-proof function of this utility model includes a tank body, the outer wall of the tank body is fixedly connected with a support leg, the top of the tank body is provided with a liquid inlet valve, the outer wall of the tank body is provided with a liquid outlet valve, the top of the inner wall of the tank body is fixedly connected with an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected with a squeezing plate, the squeezing plate has two symmetrically opened air outlets inside, each of the two air outlets is provided with a one-way valve, the squeezing plate has an inlet located inside the two air outlets, and a sealing component is provided inside the squeezing plate.

[0007] Preferably, the sealing assembly includes two sliding shafts, which are symmetrically arranged inside the squeezing plate with the inlet as the center. Both sliding shafts are slidably connected to the squeezing plate. Limiting blocks are fixedly connected to the top of each sliding shaft, and baffles are fixedly connected to the bottom of each sliding shaft. Springs are sleeved on the outer walls of each sliding shaft. The top of each spring is fixedly connected to the limiting block, and the bottom of each spring is fixedly connected to the squeezing plate. A stop block is fixedly connected to the top of the baffle. The stop block is cone-shaped and fits against the inner wall of the inlet. A funnel is fixedly connected to the top of the squeezing plate and above the inlet.

[0008] Preferably, the outer wall of the stop is provided with a rubber pad.

[0009] Preferably, a bracket is fixedly connected to the top of the tank, and a rain cover is fixedly connected to the top of the bracket. The top of the rain cover is configured as an annular inclined surface.

[0010] Preferably, the rain cover has an internal cavity, and the bottom of the rain cover has several air inlets at equal intervals, which communicate with the cavity. An air pump is fixedly connected to the top of the rain cover, and the output end of the air pump is fixedly connected to a pipe, one end of which extends into the cavity.

[0011] Preferably, the cavity is provided with a top plate, the top of the top plate is fixedly connected to a sponge pad, the top of the extrusion plate is fixedly connected to four top rods at equal intervals, the top of the top rods penetrates the tank body, the bottom of the rain cover is provided with four slots at equal intervals, and the top rods fit into the inner wall of the slots.

[0012] Preferably, the outer wall of the tank is provided with a control panel, which is electrically connected to the electric telescopic rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The ethylene glycol storage device with moisture-proof function described in this utility model, through the cooperation of spring and stop block, seals the extrusion plate when the injection of ethylene glycol stops, so that the ethylene glycol is stored below the extrusion plate. The extrusion plate is controlled to move downward by electric telescopic rod. Under the extrusion of the extrusion plate, the air above the ethylene glycol is squeezed out along the one-way valve, thereby separating the ethylene glycol from the air in the tank and preventing the moisture in the air in the tank from affecting the purity of the ethylene glycol.

[0015] 2. The ethylene glycol storage device with moisture-proof function described in this utility model protects the top of the tank from rain during rain by setting a rain cover to prevent rainwater from falling on the tank. When the liquid inlet valve is opened to add ethylene glycol, the air pump is started, allowing air near the liquid inlet valve to enter the cavity through the air inlet and be discharged upwards through the pipe. This prevents moisture from the surrounding area of ​​the tank from entering the tank when the liquid inlet valve is opened. The sponge pad can absorb the moisture in the air in the cavity, thus making the air around the tank drier while the air pump is pumping air. When the extrusion plate is controlled to move upwards, the push rod is inserted into the cavity along the slot, pushing the top plate upwards to squeeze the sponge pad, thereby expelling the moisture absorbed by the sponge pad. After the moisture in the sponge pad is squeezed out, it can be discharged through the air inlet of the rain cover. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 6 As shown, this utility model provides a technical solution: an ethylene glycol storage device with moisture-proof function, including a tank 1. Support legs 11 are fixedly connected to the outer wall of the tank 1. An inlet valve 12 is provided at the top of the tank 1, and an outlet valve 13 is provided on the outer wall of the tank 1. An electric telescopic rod 14 is fixedly connected to the top of the inner wall of the tank 1. A pressure plate 15 is fixedly connected to the output end of the electric telescopic rod 14. Two symmetrical air outlets 16 are opened inside the pressure plate 15, and a one-way valve 17 is provided inside each of the two air outlets 16. An inlet 2 is opened inside the pressure plate 15 between the two air outlets 16. A sealing assembly is provided inside the pressure plate 15. It includes two sliding shafts 21, which are symmetrically arranged inside the extrusion plate 15 with the liquid inlet 2 as the center. Both sliding shafts 21 are slidably connected to the extrusion plate 15. The top of each sliding shaft 21 is fixedly connected to a limit block 22, and the bottom of each sliding shaft 21 is fixedly connected to a baffle 24. The outer wall of each sliding shaft 21 is fitted with a spring 23. The top of the spring 23 is fixedly connected to the limit block 22, and the bottom of the spring 23 is fixedly connected to the extrusion plate 15. The top of the baffle 24 is fixedly connected to a stop block 25, which is cone-shaped and fits against the inner wall of the liquid inlet 2. A funnel 27 is fixedly connected to the top of the extrusion plate 15 and above the liquid inlet 2.

[0032] With the above technical solution, when storing ethylene glycol in tank 1, the inlet valve 12 is opened, and the electric telescopic rod 14 controls the extrusion plate 15 to move upward, causing the limiting block 22, baffle 24, and stop block 25 to move upward simultaneously. When the limiting block 22 moves to the top of tank 1, under the extrusion of tank 1, the sliding shaft 21 slides downward within the extrusion plate 15, driving the baffle 24 to move downward, causing the stop block 25 to move downward. After the stop block 25 moves downward, it separates from the inlet 2, making it easier to inject ethylene glycol into tank 1 through the inlet valve 12. The ethylene glycol entering tank 1 flows along the funnel 27 and the inlet 2 to the area below the extrusion plate 15, and the limiting block 22 moves upward. After the movement, the spring 23 is compressed, and then the electric telescopic rod 14 controls the squeezing plate 15 to move downward. When the limiting block 22 separates from the tank 1, the sliding shaft 21 moves upward within the squeezing plate 15 under the action of the spring 23, driving the baffle 24 and the stop block 25 to move upward. The stop block 25 seals the liquid inlet 2, thereby keeping the ethylene glycol below the squeezing plate 15. The electric telescopic rod 14 continues to control the squeezing plate 15 to move downward. Under the squeezing of the squeezing plate 15, the air above the ethylene glycol is squeezed out along the one-way valve 17, thereby separating the ethylene glycol from the air in the tank 1 and preventing the moisture in the air in the tank 1 from affecting the purity of the ethylene glycol.

[0033] Specifically, the outer wall of the stop 25 is provided with a rubber pad 26.

[0034] Through the above technical solution, the rubber pad 26 is set to improve the sealing performance of the baffle 25 to the liquid inlet 2, thereby improving the sealing performance of the extrusion plate 15.

[0035] Specifically, a bracket 3 is fixedly connected to the top of the tank 1, and a rain cover 31 is fixedly connected to the top of the bracket 3. The top of the rain cover 31 is set as an annular slope.

[0036] The above technical solution, through the rain cover 31, protects the top of the tank 1 when it rains, preventing rainwater from falling on the tank 1 and avoiding rainwater from seeping into the tank 1.

[0037] Specifically, the rain cover 31 has an internal cavity 32, and the bottom of the rain cover 31 has several air inlets 33 at equal intervals, which are connected to the cavity 32. The top of the rain cover 31 is fixedly connected to an air pump 34, and the output end of the air pump 34 is fixedly connected to a pipe 35, one end of which extends into the interior of the cavity 32.

[0038] With the above technical solution, when it is necessary to open the liquid inlet valve 12 to inject ethylene glycol into the tank 1, the air pump 34 is started so that the air near the liquid inlet valve 12 enters the cavity 32 along the air inlet 33 and is discharged upward along the pipe 35, thereby preventing moisture around the tank 1 from entering the tank 1 when the liquid inlet valve 12 is opened.

[0039] Specifically, a top plate 36 is provided inside the cavity 32, and a sponge pad 37 is fixedly connected to the top of the top plate 36. Four top rods 38 are fixedly connected at equal intervals to the top of the extrusion plate 15. The top of the top rods 38 penetrates the tank body 1. Four slots 39 are opened at equal intervals at the bottom of the rain cover 31, and the top rods 38 fit into the inner wall of the slots 39.

[0040] Through the above technical solution, the sponge pad 37 can absorb the moisture in the air inside the cavity 32, thereby making the air around the tank 1 drier while the air pump 34 is drawing air. When the extrusion plate 15 is moved upward to inject ethylene glycol into the tank 1, the upward movement of the extrusion plate 15 drives the push rod 38 to move upward, so that the push rod 38 is inserted into the cavity 32 along the slot 39. After the push rod 38 enters the cavity 32, it pushes the top plate 36 to move upward, squeezing the sponge pad 37, thereby expelling the moisture absorbed in the sponge pad 37. After the moisture in the sponge pad 37 is squeezed out, it can be discharged out of the rain cover 31 along the air inlet 33.

[0041] Specifically, a control panel 18 is provided on the outer wall of the tank body 1, and the control panel 18 is electrically connected to the electric telescopic rod 14.

[0042] With the above technical solution, the start and stop of the electric telescopic pole 14 can be controlled through the control panel 18.

[0043] In use, when storing ethylene glycol in tank 1, the inlet valve 12 is opened, and the electric telescopic rod 14 controls the squeezing plate 15 to move upward, causing the limiting block 22, baffle 24, and stop block 25 to move upward simultaneously. When the limiting block 22 moves to the top of tank 1, under the squeezing of tank 1, the sliding shaft 21 slides downward within the squeezing plate 15, driving the baffle 24 downward, causing the stop block 25 to move downward. After the stop block 25 moves downward, it separates from the inlet 2, making it easier to inject ethylene glycol into tank 1 through the inlet valve 12. The ethylene glycol entering tank 1 flows along the funnel 27 and the inlet 2 to the squeezing plate 15. Below, after the limiting block 22 moves upward, the spring 23 is compressed. Then, the electric telescopic rod 14 controls the squeezing plate 15 to move downward. When the limiting block 22 separates from the tank 1, under the action of the spring 23, the sliding shaft 21 moves upward within the squeezing plate 15, driving the baffle 24 and the stop block 25 to move upward. The stop block 25 seals the inlet 2, thus keeping the ethylene glycol below the squeezing plate 15. The rubber gasket 26 improves the sealing of the stop block 25 to the inlet 2, ensuring a good seal for the squeezing plate 15. The electric telescopic rod 14 continues to control the squeezing plate 15 to move downward. Under pressure, the air above the ethylene glycol is forced out along the one-way valve 17, thereby separating the ethylene glycol from the air inside the tank 1. This prevents moisture in the air inside the tank 1 from affecting the purity of the ethylene glycol. A rain cover 31 protects the top of the tank 1 from rain, preventing rainwater from falling onto the tank 1 and seeping into it. When it is necessary to open the inlet valve 12 to inject ethylene glycol into the tank 1, the air pump 34 is activated, causing air near the inlet valve 12 to enter the cavity 32 through the air inlet 33 and be discharged upwards along the pipe 35. This prevents moisture around the tank 1 from entering the tank when the inlet valve 12 is opened. Inside the tank 1, the sponge pad 37 absorbs moisture from the air in the cavity 32, thereby making the air around the tank 1 drier while the air pump 34 is drawing air. When the extrusion plate 15 moves upward to inject ethylene glycol into the tank 1, the upward movement of the extrusion plate 15 drives the push rod 38 to move upward, so that the push rod 38 is inserted into the cavity 32 along the slot 39. After the push rod 38 enters the cavity 32, it pushes the top plate 36 to move upward, squeezing the sponge pad 37, thereby expelling the moisture absorbed in the sponge pad 37. After the moisture in the sponge pad 37 is squeezed out, it can be discharged through the air inlet 33 to the rain cover 31.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
