Description

Technical Field

[0001] This utility model relates to the field of butanediol storage technology, and more specifically to a butanediol storage tank. Background Technology

[0002] Butylene glycol is an important organic compound in the chemical industry, widely used in polyester resins, polyurethanes, cosmetics, pharmaceuticals, and many other fields. With the continuous development of these industries, the demand for butylene glycol is increasing, and its production scale and storage volume are expanding accordingly.

[0003] For example, in the production of polyester resin, butanediol is a key raw material. Large-scale production enterprises need a stable and large supply of butanediol, which requires suitable storage facilities to ensure the continuity of production. However, when butanediol is stored in storage tanks, it is easily corroded by butanediol, which can lead to tank leakage. Furthermore, the shaking of butanediol during transportation or daily operation may cause a large impact on the tank, and long-term accumulation may lead to tank damage. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a butanediol storage tank to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a butanediol storage tank, including a tank body and a frame, the tank body is located on the top of the frame, two support seats are fixedly connected to the top of the frame, and the tank body is fixed to the support seats, the tank body includes a stainless steel layer, an insulating layer is fixedly connected to the inner wall of the stainless steel layer, and an anti-corrosion coating is provided on the inner wall of the insulating layer, a central baffle is fixedly connected to the center of the tank body, one side of the central baffle is bent into a V-shaped fold, and a liquid inlet is provided on the top of the tank body, with a pressure cap provided inside the liquid inlet.

[0006] As a further embodiment of this utility model, a pump body is fixedly connected to the top of the frame, a liquid inlet end of the pump body is fixedly connected to a liquid suction pipe, and the liquid suction pipe is located at the bottom of one side of the tank body and connected to the tank body, and a liquid outlet end of the pump body is fixedly connected to a drain pipe.

[0007] As a further embodiment of this utility model, a first switch valve is provided on the outside of the liquid extraction tube, and a second switch valve is provided on the outside of the liquid discharge tube.

[0011] As a further embodiment of this utility model, the outer circumferential wall of the tank is fixedly connected with a plurality of evenly distributed ribs, and a rib groove is provided on one side of the ribs.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model utilizes an anti-corrosion coating and a middle baffle. The anti-corrosion coating is made of polytetrafluoroethylene, which increases the corrosion resistance of the tank and prevents the tank from being corroded by butanediol. At the same time, the V-shaped fold on the middle baffle can block the shaking of butanediol and disperse the force of the shaking, preventing the butanediol from impacting the tank and improving the service life of the tank.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figures 1-3 This utility model provides a butanediol storage tank, including a tank body 1 and a frame 3. The tank body 1 is located on top of the frame 3. Two support seats 2 are welded to the top of the frame 3, and the tank body 1 is fixed to the support seats 2. The tank body 1 includes a stainless steel layer 19, and an insulating layer 20 made of rubber is bonded to the inner wall of the stainless steel layer 19. The inner wall of the insulating layer 20 is provided with an anti-corrosion coating 21 made of polytetrafluoroethylene. A central baffle 14 is welded to the center of the tank body 1, and one side of the central baffle 14 is bent into a V-shaped flange 15. A liquid inlet 10 is provided at the top of the tank body 1. A pressure cap 11 is provided inside the inlet 10. After opening the pressure cap 11, butanediol is added into the tank 1 through the inlet 10. Since polytetrafluoroethylene is sprayed on the inside of the tank 1 to form an anti-corrosion coating 21, the anti-corrosion coating 21 inside the tank 1 can increase the anti-corrosion performance of the tank 1 and prevent the tank 1 from being corroded by butanediol. At the same time, the middle baffle 14 inside the tank 1 can block the sloshing of butanediol, and the V-shaped fold 15 on the middle baffle 14 can disperse the force of the sloshing and impacting of butanediol on the middle baffle 14, preventing the butanediol from impacting the tank 1 and improving the service life of the tank 1.

[0022] In this invention, a pump body 8 is bolted to the top of the frame 3. A suction pipe 5 is bolted to the inlet end of the pump body 8, and the suction pipe 5 is located at the bottom of one side of the tank 1 and connected to the tank 1. A drain pipe 6 is bolted to the outlet end of the pump body 8. A first switch valve 4 is located on the outside of the suction pipe 5, and a second switch valve 7 is located on the outside of the drain pipe 6. When butylene glycol needs to be removed, the first switch valve 4 and the second switch valve 7 are opened, and then the pump body 8 is started. The pump body 8 will draw out the butylene glycol from the tank 1 through the suction pipe 5 and discharge it through the drain pipe 6, thus removing the butylene glycol for use. A pressure gauge 12 is installed on the top of the tank 1 to detect the internal pressure of the tank 1. By detecting the internal pressure of the tank 1 through the pressure gauge 12, the pressure inside the tank 1 can be monitored in real time to prevent excessive pressure inside the tank 1. A pressure gauge is bolted to the inner wall of the top of the tank 1 to monitor the internal pressure of the tank 1. A radar level gauge 13 is used to detect the liquid level inside the tank 1, allowing staff to easily understand the liquid level height inside the tank 1. Both ends of the tank 1 are integrally formed with conical surfaces 9. The conical structure helps to evenly distribute the pressure to all parts of the container, resulting in lower pressure at the bottom and reducing the pressure burden at the bottom. At the same time, it helps to improve the load-bearing capacity and stability of the container when it needs to carry a large amount of liquid or carry out violent chemical reactions. A polyurethane foam insulation layer 18 is bonded to the outside of the stainless steel layer 19. The polyurethane foam insulation layer 18 can improve the insulation performance of the tank 1. Multiple evenly distributed ribs 17 are fixed to the outer circumference of the tank 1 by bolts. A rib groove 16 is opened on one side of the ribs 17. Installing the ribs 17 on the outside of the tank 1 can strengthen the tank 1, thereby improving the overall strength of the tank 1 and improving the impact resistance of the tank 1.

[0023] The working principle of this utility model is as follows: In use, the pressure cap 11 is opened, and then butanediol is added into the tank 1 through the inlet 10. Since polytetrafluoroethylene is sprayed on the inside of the tank 1 to form an anti-corrosion coating 21, the anti-corrosion coating 21 inside the tank 1 can increase the anti-corrosion performance of the tank 1 and prevent the tank 1 from being corroded by butanediol. At the same time, the middle baffle 14 inside the tank 1 can block the shaking of butanediol, and the V-shaped fold 15 on the middle baffle 14 can disperse the force of the shaking and impact of butanediol on the middle baffle 14, preventing butanediol from impacting the tank 1 and improving the service life of the tank 1. When it is necessary to remove the butanediol, the first switch valve 4 and the second switch valve 7 are opened, and then the pump body 8 is started. The pump body 8 will draw out the butanediol in the tank 1 through the suction pipe 5 and discharge the butanediol through the drain pipe 6, thereby removing the butanediol for use.
