Description

Technical Field

[0001] The utility model belongs to the technical field of isobutane, in particular to an isobutane storage device. Background Technique

[0002] Isobutane is a colorless flammable gas at normal temperature and pressure. It is slightly soluble in water and soluble in ethanol, ether, etc. It mainly exists in natural gas, refinery gas and cracking gas, and is obtained by physical separation, etc., and can also be prepared by isomerization of n-butane. It is mainly used for alkylation with isobutene to produce isooctane as an improver for gasoline octane number. It can also be used as a refrigerant. Isobutane needs to be stored at low temperature, so a refrigerator is required for refrigeration. However, during the refrigeration process, there is no stirring and mixing function, which will affect the uniformity of refrigeration.

[0003] After retrieval, a Chinese patent document (authorized announcement number CN218378980U) is an isobutane storage device, in which there are a heat insulation box, a storage tank and a coiled tube. The storage tank is arranged inside the heat insulation box, and the top and bottom of the storage tank are respectively fixed inside the heat insulation box through fixed columns. A vacuum heat insulation cavity is formed between the heat insulation box and the storage tank; the utility model forms a vacuum heat insulation cavity by setting a heat insulation box. When in use, the inside of the vacuum heat insulation cavity is pumped to a vacuum. Since the inside of the vacuum heat insulation cavity is in a vacuum state and lacks a heat transfer medium, the external heat is not easily transferred to the storage tank, reducing the heat transfer effect, improving the heat preservation effect, reducing the use of refrigeration equipment, and saving energy and protecting the environment. Isobutane needs to be refrigerated by a refrigerator, but during the refrigeration process, there is no stirring and mixing function, which will affect the uniformity of refrigeration. Content of the Utility Model

[0004] The purpose of the utility model is to provide an isobutane storage device to solve the problems raised in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an isobutane storage device, including:

[0006] A storage tank storing isobutane;

[0007] A heat preservation box, and two fixing frames for fixing the storage tank are arranged in the inner cavity of the heat preservation box;

[0008] Two vertical inner walls of the heat preservation box are both connected with assembly plates through bolts. A bearing is connected between the two assembly plates, and the inner wall of the bearing is detachably connected with a plurality of stirring blades made of iron materials;

[0013] As a preferred embodiment, the insulation box is connected to a counterweight plate through a plurality of heat insulation blocks. The top end of the counterweight plate is connected to a heat insulation plate on one side of the insulation box, and a vacuum pump is also installed on the side of the heat insulation plate.

[0016] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0017] During the use of this isobutane storage device, the refrigerating part of the semiconductor refrigeration chip can cool down the air in the insulation box.

[0031] The inside of the incubator 2 of this application is in a low-temperature environment, and one side of the heat insulation board 17 is in a hot environment. Therefore, the degree of the heat insulation function of multiple structures needs to be selected according to actual needs. In addition, the heat dissipation and refrigeration instruments are customized and specially processed according to the usage requirements. For example, the heat dissipation part of the semiconductor refrigeration chip will be specially heat-dissipated to reduce the impact on the incubator.

[0033] A storage tank 1 stores isobutane. A maintenance door with a lock is rotatably connected to the side of the storage tank 1. The maintenance door has its own sealing structure to ensure the sealing performance;

[0034] An incubator 2, and two fixing frames 3 for fixing the storage tank 1 are arranged in the inner cavity of the incubator 2;

[0035] Both vertical inner walls of the incubator 2 are connected with assembly plates 4 by bolts. A bearing 5 is connected between the two assembly plates 4. The inner wall of the bearing 5 is detachably connected with a plurality of stirring blades 6 made of iron materials.

A plurality of magnetic blocks 9 that attract the iron material stirring blades 6 are connected to the bottom end of the horizontal support plate 8. The servo motor 7 drives the horizontal support plate 8 to rotate, and then drives the magnetic blocks 9 to rotate. Due to the attraction between the magnetic blocks 9 and the iron material stirring blades 6, the rotation of the magnetic blocks 9 can drive the rotation of the stirring blades 6, realizing the stirring of the air in the incubator 2 and the uniformity of refrigeration.

[0036] The detachable design of the assembly plate 4 and the stirring blade 6 also facilitates the movement of the positions of the bearing 5 and the stirring blade 6, and is convenient for the up and down movement of the storage tank 1.

[0037] To meet different usage requirements, a support plate 10 is connected to the inner wall of the fixing frame 3. Rubber pads are bonded to the sides of the fixing frame 3 and the support plate 10. The lower fixing frame 3 is connected and fixed to the incubator 2 through a plurality of connecting blocks 11. The inner top wall of the incubator 2 is fixedly connected with an upper lead screw 12. The top end of the upper support plate 10 is connected with a lower lead screw 13. A threaded tube 14 is commonly threadedly connected to the outer peripheries of the upper lead screw 12 and the lower lead screw 13.

After holding the upper fixing frame 3 with one hand, rotate the threaded tube 14 with the other hand to make the fixing frame 3 move downwards, so as to fix the storage tank 1, and then close the maintenance door.

[0038] The incubator 2 is connected with a counterweight plate 16 through a plurality of heat insulation blocks 15. The top end of the counterweight plate 16 is connected with a heat insulation plate 17 on one side of the incubator 2. A vacuum pump 18 is also installed on the side surface of the heat insulation plate 17. A plurality of semiconductor refrigeration chips 19 are installed on the side surface of the heat insulation plate 17. The semiconductor refrigeration chip 19 includes a refrigeration part, a connection part, a working part and a heat release part. Only the refrigeration part is inside the incubator 2, and the working part and the heat release part are outside. The refrigeration part of the semiconductor refrigeration chip 19 is installed on the inner wall of the incubator 2. The vacuum pump 8 pumps air, so that the inside of the incubator 2 is in a state close to vacuum. The refrigeration part of the semiconductor refrigeration chip 19 can cool the air inside the incubator 2. The incubator 2 is communicated with a ventilation pipe 20 which is communicated with the vacuum pump 18 and is provided with a valve.

[0040] Working principle

[0041] For this isobutane storage device, place the storage tank 1 on the lower fixing frame 3. After pressing the upper fixing frame 3 with one hand, rotate the threaded pipe 14 with the other hand, so that the fixing frame 3 moves downward, thereby fixing the storage tank 1, and then close the inspection door;

[0042] Then turn on the semiconductor refrigeration chip 19, the vacuum pump 18 and the servo motor 7. The vacuum pump 8 pumps air, so that the inside of the incubator 2 is in a state close to vacuum. The refrigeration part of the semiconductor refrigeration chip 19 can cool the air inside the incubator 2. The servo motor 7 drives the cross support plate 8 to rotate, and then drives the magnetic block 9 to rotate. Due to the attraction between the magnetic block 9 and the stirring blade 6 made of iron material, the rotation of the magnetic block 9 can drive the rotation of the stirring blade 6, realizing the stirring of the air inside the incubator 2 and achieving the uniformity of refrigeration.
