Description

Technical Field

[0001] This utility model relates to the field of chemical storage tank technology, specifically a chemical storage tank for chemical production. Background Technology

[0002] Chemical storage tanks are large, sealed steel containers used to store raw materials, intermediates, finished products, or waste chemicals. They are key static equipment in chemical production processes. Their core function is to provide a stable storage environment for flammable, explosive, corrosive, toxic, or chemically hazardous substances requiring specific temperature and pressure conditions, while ensuring safety. They are typically equipped with monitoring instruments for liquid level, temperature, and pressure, as well as auxiliary devices such as agitation and cooling systems. They are a crucial link in ensuring continuous production and logistics control.

[0003] Traditional chemical storage tanks typically use sampling valves installed on pipes or the tank body to sample internal materials. However, the current operating method has significant drawbacks: the sampling process relies entirely on operators manually opening the valves and manually supporting and suspending the sample bottles. Manual operation is difficult to guarantee stability; shaking or dropping the sample bottles can lead to sampling failure, sample contamination, or even accidents, hindering further sampling work.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Combination Figures 1 to 4 A chemical storage tank for chemical production includes a chemical tank body 1, an adjustment mechanism 2 at the bottom of the chemical tank body 1, a positioning mechanism 3 on the right side of the adjustment mechanism 2, and a sampling valve 4 fixedly connected to the outer wall of the chemical tank body 1. By setting the adjustment mechanism 2 and the positioning mechanism 3, the sampling bottle is stably supported and accurately positioned, which effectively prevents raw materials from splashing due to bottle shaking or improper position during the sampling process, and improves the safety and convenience of sampling.

[0030] The adjusting mechanism 2 includes a fixed arm 21, which is fixedly connected to the outer wall of the chemical tank body 1. A rectangular box 22 is fixedly connected to one side of the fixed arm 21. A threaded rod 23 is rotatably connected to the inner wall of the rectangular box 22. A threaded block 24 is threadedly connected to the outer wall of the threaded rod 23. A connecting arm 27 is fixedly connected to the right side of the threaded block 24. A support seat 28 is fixedly connected to the inner side of the connecting arm 27. A worm gear 25 is fixedly connected to the outer wall of the threaded rod 23. A worm 26 meshes with the outer ring of the worm gear 25. The threaded rod 23 is driven to rotate by the transmission method of the worm gear 25 and the worm 26. It has a self-locking function, which can ensure that the support seat 28 remains stable during the lifting and lowering process and after positioning, and will not slide down on its own due to the weight of the sampling bottle, thus ensuring operational reliability.

[0031] Furthermore, a rotating hole is provided on the front of the rectangular box 22, through which the worm gear 26 passes and rotates. The worm gear 26 is rotatably connected to the inner wall of the rectangular box 22. This structure ensures that the worm gear 26 runs smoothly and is subjected to uniform force during transmission, effectively extending the service life of the transmission components.

[0032] Furthermore, the threaded block 24 is slidably connected to the inner wall of the rectangular box 22, and the threaded block 24 is slidably limited to ensure that the rotational motion of the threaded rod 23 can be accurately converted into the linear motion of the threaded block 24, thereby realizing the smooth lifting and lowering of the support seat 28.

[0033] Furthermore, a long opening is provided on the right side of the rectangular box 22, through which the connecting arm 27 passes. The long opening provides ample space for the connecting arm 27 to move smoothly, enabling it to drive the support base 28 to complete the lifting stroke, while ensuring the integrity of the structure.

[0034] Example 2

[0035] See Figures 1 to 4Furthermore, based on Embodiment 1, the positioning mechanism 3 further includes a support frame 31, which is fixedly connected to the bottom of the support base 28. A threaded rod 32 is rotatably connected to the inner wall of the support frame 31, and a rectangular plate 33 is threadedly connected to the outer wall of the threaded rod 32. A short shaft 34 is fixedly connected to the top of the rectangular plate 33, and an arc block 35 is fixedly connected to the top of the short shaft 34. By rotating a threaded rod 32, the two rectangular plates 33 can be driven to move synchronously in opposite directions, thereby quickly adjusting the distance between the two arc blocks 35. This achieves rapid adaptation and clamping of sampling bottles of different diameters and has strong versatility.

[0036] Furthermore, the rectangular plate 33 is slidably connected to the inner wall of the support frame 31, and the threads on the outer walls of the two ends of the threaded rod 32 are opposite in direction. The design of opposite thread directions enables the two rectangular plates 33 to move synchronously and symmetrically, ensuring that the sampling bottle is always clamped in the center position, with uniform clamping force and good stability.

[0037] Furthermore, the support frame 31 has a rotating hole 2 on the front, through which the threaded rod 2 32 passes and rotates. The rotating hole 2 provides a stable rotation fulcrum for the threaded rod 2 32, ensuring smooth and stable transmission and avoiding jamming.

[0038] Furthermore, there are two arc-shaped blocks 35, and the inner side of both arc-shaped blocks 35 is provided with anti-slip texture. The design of the arc-shaped blocks 35 increases the contact area with the sampling bottle, and the anti-slip texture effectively increases the friction, preventing the sampling bottle from sliding or rotating after clamping, and ensuring a firm and reliable clamping.

[0039] Furthermore, slots are provided at the top of the support frame 31 and the bottom of the support base 28, and the short shaft 34 passes through the slots. The slots provide guidance and space for the movement of the short shaft 34, ensuring that the arc block 35 can move in a straight line strictly according to the predetermined trajectory and accurately perform clamping and releasing actions.

[0040] Furthermore, the arc-shaped block 35 is slidably connected to the inner wall of the support base 28, and the front ends of the threaded rod 32 and the worm gear 26 are both fixedly connected to handwheels to slide and limit the arc-shaped block 35, making its movement more stable; the design of the handwheel provides a labor-saving and convenient operation method, making lifting and clamping actions easy to complete, resulting in a good user experience.

[0041] In actual operation, when this device is used and it is necessary to sample the chemical raw materials inside the chemical tank body 1, the sampling bottle can first be placed on the top of the support base 28. Then, the handwheel at the front end of the threaded rod 32 is turned to rotate the threaded rod 32. Since the rectangular plate 33 slides and is limited on the inner wall of the support frame 31, and the threaded rod 32 and the rectangular plate 33 are threadedly connected, and the threads on the outer walls of the two ends of the threaded rod 32 are opposite in direction, the two rectangular plates 33 will move closer to each other. The rectangular plate 33 can drive the arc block 35 to move through the short shaft 34, so that the arc block 35 can clamp and limit the sampling bottle, ensuring the stability of the sampling bottle during the sampling process. At the same time, it can be used for positioning sampling bottles of different sizes.

[0042] The handwheel at the front end of the worm 26 is turned to rotate the worm 26. Since the worm 26 and the worm wheel 25 are meshed, the worm 26 will drive the threaded rod 23 to rotate through the worm wheel 25. The threaded block 24 slides and limits the movement of the threaded rod 23 on the inner wall of the rectangular box 22, so the rotational motion of the threaded rod 23 is converted into the linear motion of the threaded block 24. The threaded block 24 can drive the support seat 28 to rise through the connecting arm 27, so that the discharge port at the bottom of the sampling valve 4 can extend into the interior of the sampling bottle, reducing splashing during the sampling process. At the same time, it can be used for sampling operations on different sampling bottles.
