[0001] This utility model relates to the field of hazardous materials storage technology, and in particular to a methylamine storage tank. Background Technology

[0002] Currently, methylamine is an important basic chemical raw material, and it is widely used in the production and preparation of new energy materials, chemical synthesis, additives and other products. According to the characteristics of methylamine, its storage tanks need to meet the requirements of pressure or low temperature and normal pressure storage to ensure a stable supply of materials in chemical production, new energy material synthesis and other processes.

[0003] Among them, a search revealed Chinese patent CN207015902U, which discloses a methylamine storage tank. In the application of the above patent's technical solution, due to the limited and uneven distribution of the U-shaped coils within the tank, the cooling effect of the refrigerant flowing through the U-shaped coils on the methylamine in the tank is not good. Therefore, in order to better realize the methylamine cooling function, promote technological progress in the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the cooling structure of the storage tank in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem of poor cooling effect of the U-shaped coil in the existing storage tank on the methylamine inside the tank when the refrigerant flows through it, and to propose a methylamine storage tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A methylamine storage tank includes a tank body. The tank body is equipped with a cooling assembly, which includes a first temperature-conducting pipe and a second temperature-conducting pipe. The two ends of the first temperature-conducting pipe are respectively fixedly connected to a sealing head and a coolant inlet pipe, and the two ends of the second temperature-conducting pipe are respectively fixedly connected to a coolant outlet pipe and a connecting pipe. A connection port is provided at the bottom of one end of the outer surface of the first temperature-conducting pipe, and one end of the connecting pipe is fixedly connected to the connection port. One end of the coolant inlet pipe and one end of the coolant outlet pipe both extend out of one side of the outer surface of the tank body.

[0007] Furthermore, the first temperature-conducting tube is a straight L-shaped stainless steel tube, and the second temperature-conducting tube is a spring-shaped L-shaped stainless steel tube.

[0008] Furthermore, mounting plates are fixedly connected to the outer surfaces of both ends of the first temperature-conducting tube, and the mounting plates are fixedly connected to the inner surface of the tank.

[0009] Furthermore, the first temperature-conducting tube is provided with a guiding assembly, which includes multiple first guide plates and multiple second guide plates. The first guide plates and the second guide plates are respectively fixedly connected to the bottom and top of the inner surface of the first temperature-conducting tube, and the multiple first guide plates and the multiple second guide plates are alternately distributed inside the first temperature-conducting tube.

[0010] Furthermore, a common connecting rod is fixedly connected between the plurality of first guide plates and the plurality of second guide plates, and one end of the connecting rod is fixedly connected to the inner surface of the sealing head.

[0011] Furthermore, the tank body is provided with a protective component, which includes a protective frame. A first rubber pad is fixedly connected to the inner surface of the protective frame, and the four sides of the outer surface of the tank body are in contact with the first rubber pads on the four sides of the inner surface of the protective frame.

[0012] Furthermore, the two ends of the protective frame are respectively fixed with limit plates by bolts, and a second rubber pad is fixedly connected to the inner surface of one side of the limit plate, and the second rubber pad is in contact with the outer surface of the tank.

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

[0014] 1. By combining the first and second heat-conducting pipes in the cooling component, the cooling component has a wider temperature heat exchange range in the tank, ensuring a uniform temperature reduction effect in the tank.

[0015] 2. The design of the spring-shaped 316L stainless steel tube allows the coolant to travel a longer distance in the second temperature-conducting tube, while the guiding component in the first temperature-conducting tube can slow down the flow speed of the coolant in the first temperature-conducting tube, ensuring that the coolant can fully exchange heat and cool down the temperature inside the tank when it flows in the cooling component.

[0016] 3. Through the design of the protective components, the protective frame can prevent the tank from deforming due to impact, the two limiting plates can prevent the tank from shaking during transportation, and the first and second rubber pads can fill and separate the gaps between the tank and the protective frame and the limiting plates respectively, preventing collisions between the tank and the protective components, and ensuring the safe transportation of the methylamine storage tank.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-6 A methylamine storage tank includes a tank body 1. A cooling assembly 2 is installed inside the tank body 1. The cooling assembly 2 includes a first temperature-conducting pipe 201 and a second temperature-conducting pipe 204. A sealing head 202 and a coolant inlet pipe 203 are welded to both ends of the first temperature-conducting pipe 201, respectively. A coolant outlet pipe 205 and a connecting pipe 206 are welded to both ends of the second temperature-conducting pipe 204, respectively. A connection port is provided at the bottom of one end of the outer surface of the first temperature-conducting pipe 201, and one end of the connecting pipe 206 is welded into the connection port. One end of the coolant inlet pipe 203 and one end of the coolant outlet pipe 205 both extend out of one side of the outer surface of the tank body 1. Through the combined design of the first temperature-conducting pipe 201 and the second temperature-conducting pipe 204 in the cooling assembly 2, the cooling assembly 2 has a wider temperature heat exchange range within the tank body 1, ensuring a uniform temperature reduction effect within the tank body 1.

[0026] The first temperature conducting tube 201 is a straight tube made of 316L stainless steel, and the second temperature conducting tube 204 is a spring-shaped 316L stainless steel tube. The design of the spring-shaped 316L stainless steel tube allows the coolant to have a longer travel distance in the second temperature conducting tube 204.

[0027] like Figure 5 As shown, a guide assembly 4 is provided inside the first temperature conducting pipe 201. The guide assembly 4 includes multiple first guide plates 401 and multiple second guide plates 402. The first guide plates 401 and the second guide plates 402 are respectively welded to the bottom and top of the inner surface of the first temperature conducting pipe 201. The multiple first guide plates 401 and multiple second guide plates 402 are alternately distributed inside the first temperature conducting pipe 201. The guide assembly 4 inside the first temperature conducting pipe 201 can slow down the flow rate of the coolant in the first temperature conducting pipe 201, ensuring that the coolant can fully exchange heat and cool down the temperature inside the tank 1 when it flows in the cooling assembly 2. The multiple first guide plates 401 and multiple second guide plates 402 are welded together with the same connecting rod 403, and one end of the connecting rod 403 is welded to the inner surface of the sealing head 202.

[0028] During welding, multiple first guide plates 401, second guide plates 402 and connecting rods 403 are welded first, and then the whole assembly is placed inside the first temperature conducting tube 201. Welding starts from both ends of the outermost first guide plate 401 and second guide plate 402. Finally, the sealing head 202 and the coolant inlet pipe 203 are welded to the first temperature conducting tube 201.

[0029] Mounting plates 3 are welded to the outer surfaces of both ends of the first temperature-conducting pipe 201, and the mounting plates 3 are welded and fixed to the inner surface of the tank body 1.

[0030] The tank body 1 is provided with a protective component 5. The protective component 5 includes a protective frame 501. A first rubber pad 502 is bonded to the inner surface of the protective frame 501. The four sides of the outer surface of the tank body 1 are in contact with the first rubber pad 502 on the four sides of the inner surface of the protective frame 501. The two ends of the protective frame 501 are fixed with limit plates 503 by bolts. A second rubber pad 504 is bonded to the inner surface of one side of the limit plate 503. The second rubber pad 504 is in contact with the outer surface of the tank body 1. The first rubber pad 502 and the second rubber pad 504 can be selected as 5mm thick nitrile rubber.

[0031] The design of the protective component 5 ensures that the protective frame 501 can prevent the tank 1 from being deformed by impact, the two limiting plates 503 prevent the tank 1 from shaking during transportation, and the first rubber pad 502 and the second rubber pad 504 can fill and separate the gaps between the tank 1 and the protective frame 501 and the limiting plate 503 respectively, preventing collisions between the tank 1 and the protective component 5, and ensuring the safe transportation of the methylamine storage tank.

[0032] The working principle of this embodiment is as follows: When in use, the tank 1 is filled with methylamine gas, and the tank 1 is equipped with a thermometer, pressure gauge, safety valve and other structures.

[0033] Subsequently, the operators first connected one end of the refrigerant inlet pipe 203 to the pump outlet. The pump inlet was connected to the refrigerant storage tank via a pipe, while one end of the refrigerant outlet pipe 205 was connected to the refrigerant recovery tank. Then, during the storage of methylamine in tank 1, the operators could use the pump to transfer the refrigerant from the storage tank to the cooling assembly 2. The refrigerant in the cooling assembly 2 was then recovered into the refrigerant recovery tank via the refrigerant outlet pipe 205. As the refrigerant flowed through the cooling assembly 2, the first and second temperature-conducting pipes 201 and the refrigerant within them cooled the methylamine in tank 1, maintaining the temperature within tank 1 within the range of 0℃-10℃. As the temperature decreases, the pressure inside the storage tank is further reduced, preventing the tank from exploding. The design of the first temperature-conducting pipe 201 as a straight 316L stainless steel pipe and the second temperature-conducting pipe 204 as a spring-shaped 316L stainless steel pipe allows the cooling component 2 to have a wider temperature heat exchange range inside the tank 1, ensuring a uniform temperature reduction effect inside the tank 1. At the same time, the spring-shaped 316L stainless steel pipe allows the coolant to have a longer travel distance in the second temperature-conducting pipe 204, while the guide component 4 inside the first temperature-conducting pipe 201 can slow down the flow speed of the coolant in the first temperature-conducting pipe 201, ensuring that the coolant can fully exchange heat and cool down the temperature inside the tank 1 when it flows in the cooling component 2.

[0034] When the methylamine storage tank is moved or transported, the protective frame 501 in the protective assembly 5 provides external protection for the tank body 1 to prevent the tank body 1 from being deformed due to impact. The limiting plate 503 limits the tank body 1 within the protective frame 501 to prevent the tank body 1 from shaking during transportation. The first rubber pad 502 and the second rubber pad 504 can fill and separate the gaps between the tank body 1 and the protective frame 501 and the limiting plate 503 respectively, to prevent the tank body 1 from colliding with the protective assembly 5, thus ensuring the safe transportation of the methylamine storage tank.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
