[0026] Please refer to Figures 1 to 7, a cyclohexane storage device according to an embodiment of the present invention, for storing cyclohexane. The cyclohexane storage device includes a storage tank 10, a cooling device 20, and a mounting bracket 30; the storage tank 10 is mounted on the mounting bracket 30. The storage tank 10 includes an inner tank 11 and an outer tank 12. The outer tank 12 is sleeved inside the inner tank 11, and a heat insulation layer 13 is formed between the outer tank 12 and the inner tank 11. The top of the inner tank 11 extends upward to form a liquid inlet 110, and the bottom of the inner tank 11 extends downward to form a liquid outlet 111. A liquid outlet valve 112 is provided on the liquid outlet 111; the cooling device 20 is a blade 21 and a motor 22 (such as Figure 4 ) mounted on the outer tank 12. The motor 22 includes a rotating part 220. The rotating part 220 penetrates through the outer tank 12 and the inner tank 11 and extends into the inner tank 11. The blade 21 is mounted at the free end of the rotating part 220.

[0027] The working principle of the cyclohexane storage device of the present invention is as follows: The liquid inlet 110 is located at the top of the inner tank 11 and extends upward. When cyclohexane needs to be injected into the storage device, cyclohexane can smoothly flow into the inner tank 11 through the liquid inlet 110; the outer tank 12 is sleeved outside the inner tank 11, playing a role in protecting the inner tank 11 and further enhancing the structural stability; at the same time, the heat insulation layer 13 formed between the outer tank 12 and the inner tank 11 can effectively block the influence of the external temperature on the cyclohexane in the inner tank 11; when the motor 22 is started, the rotating part 220 drives the blade 21 to rotate in the inner tank 11. The stirring action of the blade 21 can make the cyclohexane in the inner tank 11 flow continuously, avoiding the situation of too high or too low temperature in a local area of the cyclohexane; the liquid outlet 111 is located at the bottom of the inner tank 11 and extends downward. The liquid outlet valve 112 provided on the liquid outlet 111 is used to control the outflow of cyclohexane; when cyclohexane needs to be taken, the liquid outlet valve 112 is opened, and the cyclohexane in the inner tank 11 flows out of the storage device through the liquid outlet 111 under the action of gravity.

[0028] Compared with the prior art, for the cyclohexane storage device involved in the present utility model, the design of the inner tank 11 and the outer tank 12 provides double protection for cyclohexane; the inner tank 11 directly stores cyclohexane, ensuring its sealing performance and preventing leakage; the outer tank 12 provides additional protection externally, which can resist external impacts, collisions and other accidents, reducing the risk of cyclohexane leakage; even if there is a slight leakage in the inner tank 11, the outer tank 12 can also play a role in containing to a certain extent, buying time for taking remedial measures in a timely manner; the heat insulation layer 13 effectively blocks the influence of external temperature changes on cyclohexane; it can prevent cyclohexane from accelerating volatilization due to too high temperature, reducing potential explosion hazards; at the same time, it can also prevent cyclohexane from solidifying in a low-temperature environment, ensuring the stability of storage; the stirring of the blades 21 can make the temperature of cyclohexane uniform, avoiding local overheating or overcooling, and can also enhance the heat exchange between cyclohexane and the wall of the inner tank 11; during the long-term storage process of cyclohexane, precipitation or stratification may occur, and the stirring of the blades 21 can effectively prevent this situation from happening, ensuring the uniform and stable quality of cyclohexane.

[0029] Please refer to Figure 3 and Figure 4 , a cooling rod 130 is arranged in the heat insulation layer 13; in this embodiment, the cooling rod 130 is a copper pipe. Since the cooling rod 130 is in contact with the outer tank 12, heat can be transferred to the outer tank 12 through the cooling rod 130 and then dissipated to the external environment by the outer tank 12, thereby realizing the active cooling of cyclohexane; on the basis of the stirring and cooling of the motor 22 and the blades 21, the cooling effect can be further improved. Especially when the external temperature is relatively high or the storage volume of cyclohexane is large and more heat is generated, the cooling rod 130 can quickly and effectively reduce the temperature of cyclohexane; the cooling rods 130 are distributed in the heat insulation layer 13, and can cool cyclohexane at different positions, making the temperature in the entire storage tank 10 more uniform and stable; even when the local temperature fluctuates greatly, the cooling rod 130 can quickly respond, absorb or release heat to adjust the temperature, and keep cyclohexane stored within a suitable temperature range.

[0030] A liquid level detection component 40 is provided on the inner tank 11. The liquid level detection component 40 includes a liquid level display box 41 mounted on the outer tank 12, a liquid level connecting rod 42, and a floating ball 43. One end of the liquid level connecting rod 42 is connected to the liquid level display box 41, and the other end penetrates through the outer tank 12 and extends into the inner tank 11. The floating ball 43 is mounted on the free end of the liquid level connecting rod 42. When cyclohexane starts to be injected into the inner tank 11, as the liquid level gradually rises, the floating ball 43 also starts to rise under the buoyancy of cyclohexane; the rise of the floating ball 43 drives the liquid level connecting rod 42 to move upward. Since the liquid level connecting rod 42 is connected to the liquid level display box 41, the movement of the liquid level connecting rod 42 will generate a corresponding signal change in the liquid level display box 41; after receiving the signal transmitted by the liquid level connecting rod 42, the liquid level display box 41 converts the signal into a liquid level value or an intuitive indication through internal electronic components or mechanical structures; in this embodiment, the liquid level height can be displayed by the movement of a pointer on a dial. In other embodiments, the liquid level value can also be directly displayed through a digital display screen. When the liquid level of cyclohexane in the inner tank 11 drops, the floating ball 43 will also drop accordingly, the liquid level connecting rod 42 will move downward as well, and the indication in the liquid level display box 41 will change correspondingly, reflecting the decrease in the liquid level. It can accurately monitor the liquid level and avoid the overflow of the inner tank 11 caused by excessive injection of cyclohexane; by monitoring the change of the liquid level, possible leakage situations can also be detected early; if the liquid level drops abnormally, it may mean that there is a leakage point in the storage tank 10, and the operator can take timely measures for inspection and repair to prevent the harm caused by the leakage of cyclohexane to the environment and personnel.

[0031] Please refer to Figure 3 and Figure 7, a sealing assembly 50 is provided on the liquid inlet 110. The sealing assembly 50 includes a lower flange 51 sleeved on the liquid inlet 110, an upper flange 52 is provided on the lower flange 51, through holes 53 are provided oppositely between the upper and lower flanges 51. The sealing assembly 50 further includes bolts 54 and matching nuts 55. The bolts 54 penetrate through the through holes 53, and nuts 55 are screwed on the free ends of the bolts 54 to tightly connect the upper and lower flanges 51. When it is necessary to inject cyclohexane into the storage tank 10, first ensure that the contact surface between the upper flange 52 and the lower flange 51 is clean and flat to ensure a good sealing effect; place the upper flange 52 above the lower flange 51 to align the through holes 53 of the two; then insert the bolts 54 into the through holes 53 and screw nuts 55 on the free ends of the bolts 54; as the nuts 55 are gradually tightened, the tension generated by the bolts 54 causes the upper flange 52 and the lower flange 51 to approach each other; the contact surface between the flanges is squeezed to form a sealing surface; at the sealing surface, due to the tight connection between the upper flange 52 and the lower flange 51, the leakage of cyclohexane from the liquid inlet 110 is prevented; the connection of the bolts 54 and the nuts 55 provides sufficient fastening force, so that even during the injection of cyclohexane, the pressure of the liquid will not cause the seal to fail; when the injection is completed, the sealing assembly 50 continues to maintain the sealed state of the liquid inlet 110 to prevent external air, moisture or other impurities from entering the storage tank 10 and affecting the quality and storage safety of cyclohexane.

[0032] The cyclohexane storage device further includes a hydraulic sensor 60, and the hydraulic sensor 60 is installed on the side wall of the inner tank 11. The hydraulic sensor 60 can monitor the hydraulic condition in the inner tank 11 in real time; if the hydraulic pressure exceeds the safe range, it may indicate that the storage device is abnormal, such as excessive injection of cyclohexane, volume expansion caused by a sharp rise in temperature, etc.; timely detection of the overpressure situation can take corresponding measures, such as opening the safety valve for pressure relief, to prevent the storage tank 10 from bursting due to excessive pressure, causing serious safety accidents such as leakage and even explosion; continuous monitoring of the hydraulic pressure by the hydraulic sensor 60 can also give early warning of potential safety risks and gain time for taking preventive measures.

[0033] The cyclohexane storage device further includes an evacuation assembly 70. The evacuation assembly 70 includes an evacuation pipe 71 and an evacuation valve 72. The evacuation pipe 71 penetrates through the inner tank 11 and the outer tank 12, and the evacuation valve 72 is installed on the evacuation pipe 71 on one side of the outer tank 12. When it is necessary to evacuate the storage tank 10, the evacuation valve 72 is opened; if there is gas in the storage tank 10, such as the vapor generated by the volatilization of cyclohexane or the air mixed in during the injection process, etc., these gases can be discharged from the storage tank 10 through the evacuation pipe 71; under the action of the pressure difference, the gas flows from the inner tank 11 through the evacuation pipe 71 to the outside; if the cyclohexane in the storage tank 10 needs to be completely discharged or transferred, the evacuation valve 72 can also be opened, and the cyclohexane can be discharged from the inner tank 11 through the evacuation pipe 71 by using gravity or external pressure; in the normal storage state, the evacuation valve 72 is in the closed state to ensure the tightness of the storage tank 10, prevent the leakage of cyclohexane and the entry of external impurities.

[0034] The cyclohexane storage device further includes a sampling assembly 80 provided on one side of the liquid outlet 111. The sampling assembly 80 includes a sampling pipe 81 and a sampling valve 82. The sampling pipe 81 penetrates through the outer tank 12 and the inner tank 11, and the sampling valve 82 is installed on the sampling pipe 81 on one side of the outer tank 12. When it is necessary to sample the cyclohexane in the storage tank 10, the sampling valve 82 is opened; due to the cyclohexane in the storage tank 10 under the action of pressure or due to gravity, the cyclohexane will flow out from the inner tank 11 through the sampling pipe 81; the flowing-out cyclohexane can be collected in a specific container and used as a sample for analysis and detection; for example, the purity, impurity content, physical properties and other indicators of cyclohexane can be detected to ensure that the quality of the stored cyclohexane meets the requirements; when sampling is not required, the sampling valve 82 is in the closed state to ensure the tightness of the storage tank 10 and prevent the leakage of cyclohexane. Through the sampling assembly 80, samples can be conveniently obtained from the cyclohexane storage device to monitor and analyze the quality of the stored cyclohexane, ensuring the quality stability and safety reliability of cyclohexane during storage.

[0035] Please refer to Figure 1 and Figure 2, a first ear plate 31 extends from one side of the outer tank 12, and a pushing mechanism 32 is arranged on the bracket. The pushing mechanism 32 includes an adjusting rod 320 arranged in the direction of gravity, and the first ear plate 31 is connected to the free end of the adjusting rod 320. The first ear plate 31 extending from one side of the outer tank 12 is connected to the free end of the adjusting rod 320, forming a mechanical connection between the storage tank 10 and the pushing mechanism 32; when the adjusting rod 320 moves, the force is transmitted to the storage tank 10 through the first ear plate 31; when it is necessary to increase the height of the storage tank 10, the adjusting rod 320 extends along the direction of gravity; the free end of the adjusting rod 320 pushes the first ear plate 31 upward, thereby driving the entire storage tank 10 to rise; in order to adapt to different installation height requirements and facilitate the maintenance and inspection of the bottom of the storage tank 10; on the contrary, when it is necessary to lower the height of the storage tank 10, the adjusting rod 320 shortens; the free end of the adjusting rod 320 pulls the first ear plate 31 downward to lower the storage tank 10; fine adjustment can be carried out during the installation process, or it can be used when it is necessary to lower the center of gravity of the storage tank 10 to increase stability; making the cyclohexane storage device more flexible during installation and use; the height and angle of the storage tank 10 can be adjusted according to actual needs to meet different site layouts and operation requirements; facilitating the maintenance and repair of the storage tank 10.

[0036] A second ear plate 33 extends outward from the outer tank 12 on the side opposite to the first ear plate 31. A guiding hole is arranged on the second ear plate 33, and a guiding rod 34 passing through the guiding hole is arranged on the bracket. It extends outward from the outer tank 12 on the side opposite to the first ear plate 31; it acts together with the first ear plate 31 to provide support and connection points for the installation and adjustment of the storage tank 10 on the bracket; when the pushing mechanism 32 adjusts the height or angle of the storage tank 10 through the adjusting rod 320, the guiding rod 34 slides in the guiding hole; the cooperation between the guiding rod 34 and the guiding hole can limit the movement trajectory of the storage tank 10 during the adjustment process and prevent the storage tank 10 from unnecessary shaking or deviation; for example, when the adjusting rod 320 raises the storage tank 10, the guiding rod 34 slides upward in the guiding hole to ensure that the storage tank 10 rises smoothly in the vertical direction. At the same time, the guiding rod 34 can also prevent the storage tank 10 from displacing in the horizontal direction and maintain the balance of the storage tank 10; during the normal use of the storage tank 10, the cooperation between the guiding rod 34 and the guiding hole can enhance the stability of the storage tank 10; the guiding rod 34 can bear part of the weight and external force of the storage tank 10, reducing the pressure on the adjusting rod 320 and the first ear plate 31, thereby improving the reliability and safety of the entire storage device.

[0037] A plurality of pulleys 35 are provided at the bottom of the bracket. The pulleys 35 enable the entire storage device to be easily moved on the ground. When it is necessary to move the storage device from one position to another, there is no need to use large lifting equipment or consume a large amount of manpower for handling; the storage device can be conveniently and quickly moved by manual pushing or with the aid of small traction equipment; it can adapt to different working environments and process requirements.

[0038] The above only expresses the preferred technical solutions of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these modifications and deformations.
