Technical Field

[0001] This utility model relates to the field of chemical storage tank technology, and in particular to a double-layered insulated tank body for a heat-resistant and pressure-resistant chemical storage tank. Background Technology

[0002] In the chemical production process, chemical storage tanks are important equipment for storing various chemical raw materials, intermediate products and finished products. During the use of storage tanks in the chemical production process, they often need to be moved and positioned to meet different production needs.

[0003] Existing chemical storage tanks typically require external equipment such as forklifts for movement, making the process inconvenient. Tanks equipped with rollers are prone to displacement or tipping due to the small contact area between the rollers and the ground, compromising stability and posing certain safety hazards.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a double-walled insulated tank body for a heat-resistant and pressure-resistant chemical storage tank includes a storage tank 1, a base 3 at the bottom of the storage tank 1, and a moving mechanism 4 inside the base 3.

[0021] The moving mechanism 4 includes a protective shell 401, a hidden groove 402, a lifting assembly 403, a power assembly 404, a base plate 405, casters 406, and a limiting rod 407. The hidden groove 402 is formed inside the base 3, and the outer periphery of the base plate 405 is disposed inside the hidden groove 402. The upper part of the lifting assembly 403 is disposed on the front and rear sides of the hidden groove 402, and the lower part of the lifting assembly 403 is disposed on the front and rear sides of the upper part of the base plate 405. The power assembly 404 is installed on the left side of the base 3, and the lifting assembly 403 is connected to the power assembly 404. The protective shell 401 is disposed on the left side of the base 3 and is disposed on the outer periphery of the power assembly 404. The casters 406 are installed on the base plate 405. At the lower four corners, the upper end of the limiting rod 407 is fixedly connected to the left and right sides of the top wall inside the hidden groove 402. The left and right sides of the base plate 405 are slidably connected to the outer periphery of the limiting rod 407. When it is necessary to transfer or move, the lifting component 403 is driven by the power component 404, so that the base plate 405 moves down smoothly under the restriction of the limiting rod 407, so that the casters 406 descend and lift the base 3, so that the bottom of the base 3 is lifted off the ground, and thus the casters 406 can be used to move it. When it is not necessary to move, the casters 406 are hidden inside the hidden groove 402, and the bottom of the base 3 contacts the ground, so that the storage tank 1 is placed stably in place and prevents it from moving, which is very convenient to use.

[0022] Storage tank 1 has a sandwich layer in the middle of its shell. The sandwich layer is evacuated and filled with vacuum fiber insulation material. Storage tank 1 is divided into an inner tank and an outer tank. The inner tank is made of high-temperature and high-pressure resistant materials, such as stainless steel alloy. Its inner wall is smooth, which can reduce material residue and corrosion. The outer tank is also made of high-strength pressure-resistant materials, such as Q345R steel, which has good pressure resistance. The sandwich layer is evacuated and filled with heat insulation materials, such as rock wool and glass wool, which can effectively prevent heat transfer and ensure the storage temperature of the material in the inner tank.

[0023] A magnetic level gauge 2 is installed on the outside of the storage tank 1. The capacity of the liquid material inside the storage tank 1 can be intuitively understood through the magnetic level gauge 2.

[0024] The bottom of the base 3 is equipped with an anti-slip and shock-absorbing rubber pad, which increases the stability of the base 3 when it is stationary.

[0025] The lifting assembly 403 includes a bidirectional threaded rod 4031, an internal threaded seat 4032, and a support rod 4033. The left and right ends of the bidirectional threaded rod 4031 are rotatably connected to the front and rear sides of the concealed groove 402. The middle part of the internal threaded seat 4032 is threadedly connected to the left and right sides of the bidirectional threaded rod 4031. The upper end of the support rod 4033 is rotatably connected to the lower part of the internal threaded seat 4032, and the lower end of the support rod 4033 is rotatably connected to the left and right sides of the upper part of the base plate 405. The bidirectional threaded rod 4031 is rotated by the driving power assembly 404, which causes the internal threaded seats 4032 to move closer or further away from each other. This causes the support rod 4033 to be vertical, allowing the caster wheel 406 to extend out of the concealed groove 402, or the support rod 4033 to be tilted, causing the caster wheel 406 to retract into the concealed groove 402.

[0026] The power assembly 404 includes a helical gear 4041, a connecting rod 4042, a helical gear 4043, a worm gear 4044, a worm wheel 4045, and a transmission rod 4046. One end of the connecting rod 4042 passes through the base 3 and is fixedly connected to the left end of the lifting assembly 403. The middle of the helical gear 4041 is fixedly connected to the outer periphery of the connecting rod 4042. The middle of the helical gear 4043 is fixedly connected to the front and rear ends of the transmission rod 4046. The front and rear ends of the transmission rod 4046 are rotatably connected to the front and rear sides of the protective shell 401. The helical gear 4041 and the helical gear 4043 mesh with each other. The middle of the worm wheel 4045 is fixedly connected to... In the middle of the transmission rod 4046, the lower end of the worm 4044 is rotatably connected to the middle of the protective shell 401. The upper end of the worm 4044 penetrates the wall of the protective shell 401 and is fixedly connected to a handwheel 4047. The worm 4044 and the worm wheel 4045 mesh with each other. Rotating the handwheel 4047 causes the worm 4044 to drive the worm wheel 4045, which in turn causes the transmission rod 4046 to rotate. This, in turn, drives the connecting rod 4042 to rotate through the second helical gear 4043 and the first helical gear 4041. This, in turn, causes the connecting rod 4042 to drive the bidirectional threaded rod 4031 to rotate, thereby controlling the base plate 405 to move up and down.

[0027] Working principle:

[0028] When transfer or movement is required, the power component 404 drives the lifting component 403, causing the base plate 405 to move smoothly downward under the restriction of the limit rod 407, which causes the casters 406 to descend and lift the base 3, so that the bottom of the base 3 is off the ground. This allows for easy movement via the casters 406. When movement is not required, the casters 406 are hidden inside the hiding groove 402, and the bottom of the base 3 contacts the ground, allowing the storage tank 1 to be placed stably in place and preventing it from moving. This makes it very convenient to use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
