Description

A tank-type methanol storage device Technical Field

[0001] This utility model relates to the field of methanol storage technology, specifically a tank-type methanol storage device. Background Technology

[0002] Methanol, also known as hydroxymethane, wood alcohol, or wood spirit, is an organic compound and the simplest saturated monohydric alcohol. In the current chemical industry, methanol is an important organic solvent and chemical raw material. After production, methanol is stored in storage devices. Current storage devices are equipped with multiple square storage tanks to facilitate the storage of methanol.

[0003] Several utility model patents in the field of methanol storage and processing technology are disclosed in the prior art. Among them, utility model patent with publication number CN222292551U discloses a methanol storage device with external cooling and heat insulation. The device includes a storage tank, an insulation shell fixedly connected to the outside of the storage tank, a water tank fixedly connected to the bottom of the storage tank, a condenser pipe fixedly connected to the front bottom of the water tank, a water pump fixedly connected to the other end of the condenser pipe, a water pump fixedly mounted on the right side of the storage tank on the left side, a flow pipe fixedly connected to the output end of the water pump, the other end of the flow pipe fixedly connected to the front top of the water tank, and a water inlet pipe fixedly connected to the rear side of the water tank. The other end of the water inlet pipe is threadedly connected to a liquid-blocking cap. This utility model facilitates the monitoring of the storage tank temperature, thereby enabling cooling of the tank interior when the temperature rises. It also facilitates air and water cooling of the tank body, reducing the risk of combustion and explosion caused by increased internal methanol temperature, thus improving storage safety.

[0004] However, the above methods still have the following drawbacks in actual use: most storage devices do not have a pressure relief structure. When the internal gas pressure increases due to temperature rise or other reasons, it is difficult to release the pressure in time, which may cause the storage tank to bear excessive pressure, thereby causing safety risks and reducing the applicability of the storage device. Summary of the Invention

[0005] The purpose of this invention is to provide a tank-type methanol storage device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tank-type methanol storage device, comprising a support frame, a storage cylinder fixedly connected to the top of the support frame, a pressure gauge and an exhaust pipe fixedly connected to the outer surface of the storage cylinder, a connecting box fixedly connected to the front of the support frame, a centrifugal pump fixedly connected to one side of the support frame, a connecting pipe connected to one end of the centrifugal pump, a feed pipe connected to the other side of the centrifugal pump, a controller fixedly connected to the outer surface of the exhaust pipe, a sealing plastic cylinder slidably connected inside the exhaust pipe, a sealing ball fixedly connected to one end of the sealing plastic cylinder, an exhaust port opened inside the exhaust pipe, a sealing rubber plate fixedly connected inside the exhaust pipe, a slider fixedly connected to the outer surface of the sealing ball, a guide rod fixedly connected to one side of the slider, and a telescopic device fixedly connected inside the exhaust pipe.

[0007] As a further preferred embodiment of this technical solution, one end of the exhaust pipe is connected to the connecting box, and the other end of the connecting pipe is connected to the storage cylinder.

[0008] As a further preferred embodiment of this technical solution, the sealing rubber plate is slidably connected inside the sealing plastic cylinder, and the sealing ball overlaps inside the exhaust pipe.

[0009] As a further preferred embodiment of this technical solution, a groove is provided inside the exhaust pipe, and the slider is slidably connected inside the groove.

[0010] As a further preferred embodiment of this technical solution, the guide rod is slidably connected inside the exhaust pipe, the exhaust pipe has a groove, and a fixing plate is fixedly connected to the outer surface of the guide rod.

[0011] As a further preferred embodiment of this technical solution, the guide rod is sleeved with a spring, the fixed plate is fixedly connected to the groove by the spring, and the guide rod is slidably connected to the telescopic device.

[0012] This utility model provides a tank-type methanol storage device, which has the following advantages:

[0013] (1) This utility model sets up a controller, a sealed plastic cylinder, a sealing ball, an exhaust port and a guide rod. The controller controls the telescopic device to operate, and the telescopic device will apply a thrust to the guide rod. The sealing ball will drive the sealed plastic cylinder to slide with the slider, and the sealing rubber plate will move inside the sealed plastic cylinder. When the sealing ball moves to the appropriate position, the sealing rubber plate will disengage from the exhaust port, and then the internal air pressure will be transported to the connecting box through the exhaust port. Through the cooperation between the telescopic device, the sealing rubber plate and the exhaust port, the storage device can release the excessive air pressure in the storage cylinder in time, avoid the storage device from being subjected to excessive pressure and causing safety risks, thereby ensuring the applicability of the storage device, realizing automatic pressure balance, reducing manual intervention and improving the level of automation.

[0014] (2) By setting a groove, a fixing plate and a spring, when the guide rod is subjected to tension, the fixing plate will drive the spring to deform. When the sealing ball is restored, it will contact the inside of the exhaust pipe. Then the spring will apply a pushing force to the fixing plate, so that the sealing ball and the exhaust pipe can fit tightly together and avoid gaps at the connection. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: As shown in Figures 1 and 4, in this embodiment, a tank-type methanol storage device includes a support frame 1, a storage cylinder 2 fixedly connected to the top of the support frame 1, a pressure gauge 3 and an exhaust pipe 5 fixedly connected to the outer surface of the storage cylinder 2, a connecting box 4 fixedly connected to the front of the support frame 1, a centrifugal pump 6 fixedly connected to one side of the support frame 1, a connecting pipe 7 connected to one end of the centrifugal pump 6, a feed pipe 8 connected to the other side of the centrifugal pump 6, a controller 13 fixedly connected to the outer surface of the exhaust pipe 5, a sealing plastic cylinder 10 slidably connected inside the exhaust pipe 5, a sealing ball 11 fixedly connected to one end of the sealing plastic cylinder 10, an exhaust port 12 opened inside the exhaust pipe 5, a sealing rubber plate 9 fixedly connected inside the exhaust pipe 5, a slider 14 fixedly connected to the outer surface of the sealing ball 11, a guide rod 16 fixedly connected to one side of the slider 14, and a telescopic device 17 fixedly connected inside the exhaust pipe 5.

[0022] As shown in Figures 1 and 3, one end of the exhaust pipe 5 is connected to the connecting box 4, one end of the connecting pipe 7 is connected to the storage cylinder 2, the sealing rubber plate 9 is slidably connected inside the sealing plastic cylinder 10, the sealing ball 11 overlaps inside the exhaust pipe 5, the exhaust pipe 5 has a sliding groove 15, and the slider 14 is slidably connected inside the sliding groove 15.

[0023] By setting a sealing rubber plate 9 and a sealing plastic cylinder 10, when the sealing plastic cylinder 10 is subjected to tension, it will move on the surface of the sealing rubber plate 9. When the sealing plastic cylinder 10 returns to its original position, the sealing rubber plate 9 will seal the exhaust port 12, preventing the air pressure inside the storage cylinder 2 from leaking through the exhaust port 12, thus ensuring the stability of the air pressure inside the storage cylinder 2.

[0024] As shown in Figures 3 and 4, the guide rod 16 is slidably connected inside the exhaust pipe 5. A groove 18 is provided inside the exhaust pipe 5. A fixing plate 19 is fixedly connected to the outer surface of the guide rod 16. A spring 20 is sleeved on the guide rod 16. The fixing plate 19 is fixedly connected to the groove 18 through the spring 20. The guide rod 16 is slidably connected inside the telescopic device 17.

[0025] By setting the slide groove 15, when the telescopic device 17 applies a pulling or pushing force to the sealing ball 11 through the guide rod 16, the slider 14 will slide in the slide groove 15, so that the slide groove 15 plays a certain guiding role in the movement of the sealing ball 11, and avoids the sealing ball 11 from getting stuck when moving.

[0026] This utility model provides a tank-type methanol storage device, the specific working principle of which is as follows:

[0027] When the storage device stores methanol, the centrifugal pump 6 delivers it into the storage cylinder 2 through the feed pipe 8 and connecting pipe 7. The internal pressure is then detected by the pressure gauge 3. When the internal pressure is too high, the controller 13 controls the telescopic device 17 to operate. The telescopic device 17 applies a thrust to the guide rod 16, and the sealing ball 11 drives the sealing plastic cylinder 10 to slide along with the slider 14. The sealing rubber plate 9 moves inside the sealing plastic cylinder 10. When the sealing ball 11 moves to the appropriate position, the sealing rubber plate 9 disengages from the exhaust port 12. The internal pressure is then delivered to the connecting box 4 through the exhaust port 12. When the pressure stabilizes, the sealing ball 11 and the sealing plastic cylinder 10 are reset. When the guide rod 16 moves, the fixing plate 19 on its surface causes the spring 20 to deform within the groove 18.

[0028] 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.
