Description

Technical Field

[0001] This utility model relates to a storage and protection container, and in particular to a storage and protection container for a highly active non-metallic catalyst, belonging to the field of catalyst storage technology. Background Technology

[0002] Non-metallic catalysts are a class of non-metallic materials that exhibit excellent performance in catalytic reactions. They are characterized by high efficiency, environmental friendliness, and low cost, and have gradually become a research hotspot for replacing traditional metal catalysts (especially precious metal catalysts). Due to their high activity, catalysts need to be sealed and stored in tanks before use.

[0003] In the prior art, such as the utility model application with application number 202021022829.9, a tilt-resistant vertical catalyst storage tank is disclosed. To address the problems of inconvenient transportation of existing vertical catalyst storage tanks, requiring multiple people to handle them, and the tank easily tipping over during transport due to inconsistent force applied by multiple operators, posing certain safety hazards and low reliability, this invention utilizes a screw-on connection between a lead screw and a threaded through-hole. The lead screw can be pre-rotated upwards to a position where it does not contact the adjusting ring. Then, by simultaneously controlling four electric push rods, four support rods are extended outwards. Due to the tank's own weight and the universal rollers at the bottom of the support rods, the tank is supported by the ground. The contact mechanism, as the four support rods extend outwards simultaneously, pushes the adjusting ring upwards along the direction of the tank, compressing multiple connecting springs. When the four support rods are at a certain angle, each lead screw is rotated downwards, causing the bottom end of each lead screw to be screwed into the corresponding threaded hole on the adjusting ring, locking the position of the adjusting ring and ensuring the working distance between the fixed ring and the adjusting ring. Thus, during the movement of the tank, the four support rods and the universal rollers at the bottom of the support rods work together with the casters at the bottom of the tank to move the tank, increasing the support capacity during the movement of the tank, improving the anti-tipping ability of the tank during movement, and improving the reliability of use.

[0004] The above-mentioned applications still have shortcomings:

[0005] During the support and movement of the tank, multiple sets of electric push rods are needed to unfold the support rods. The production cost of the device is high and the control is inconvenient. In addition, after the device is moved to a fixed position, the casters need to be fixed after the support rods are retracted to ensure the stability of the tank. The operation and use are inconvenient.

[0006] To address these issues, a highly active non-metallic catalyst storage and protection container was designed. Utility Model Content

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment proposes a storage and protection container for a highly active non-metallic catalyst, including a tank body 1. The tank body 1 is made of 316L stainless steel with a wall thickness of 8-12mm and an inner surface polished to Ra≤0.8μm. A base 2 is provided below the tank body 1. A column 3 is vertically fixed at one end of the top of the base 2. A buffer mechanism 4 is provided between the side of the column 3 and the tank body 1. A collar 5 is fitted on the outside of the tank body 1 and slides along the vertical direction of the tank body 1. Support rods 7 are evenly hinged at the bottom of the collar 5. The support rods 7 are made of high-strength aluminum alloy, grade 6061-T6, with an outer diameter of 40-50mm. A lifting mechanism 6 is provided on the column 3 to control the sliding of the collar 5. Universal wheels 8 are installed at the bottom of the support rods 7. An unfolding mechanism 9 is evenly arranged circumferentially at the bottom of the outside of the tank body 1. The unfolding mechanism 9 controls the unfolding and retraction of the support rods 7.

[0036] When the device is placed vertically, the support rods 7 are evenly and vertically arranged along the circumference of the tank body 1, forming a protective barrier on the outside of the tank body 1. The bottom end of the support rods 7 is located above the base 2. At this time, the tank body 1 is vertically fixed. When the tank body 1 needs to be moved, in order to ensure the stability during the movement, the lifting mechanism 6 controls the collar 5 to move downward. During the downward movement of the collar 5, the unfolding mechanism 9 unfolds multiple sets of support rods 7 outward at the same time. As the collar 5 moves downward, the universal wheels 8 at the bottom of the support rods 7 contact the ground, and the base 2 is lifted off the ground. Only the universal wheels 8 contact the ground, pushing the device to move. During the movement, the buffer mechanism 4 can reduce the shaking during the movement.

[0037] Example 2

[0038] The solution in Example 1 will be further described below with reference to its specific working method.

[0039] like Figure 1 As shown, in a preferred embodiment, based on the above method, the base 2 is further U-shaped, and the bottom of the base 2 is provided with an anti-slip pad. The U-shaped base 2 increases the contact area with the ground, and the use of the anti-slip pad increases the friction with the ground, resulting in higher placement stability.

[0040] like Figure 3As shown, in a preferred embodiment, based on the above method, the buffer mechanism 4 further includes a first slide groove 401, a first slider 402, a spring 403, and a damper 404. The first slide groove 401 is formed at the top and bottom of the inner side of the column 3. The first slider 402 is vertically slidably arranged inside the first slide groove 401. The first slider 402 is fixedly connected to the side of the tank body 1. A damper 404 is provided between the bottom end of the first slider 402 and the inner bottom of the first slide groove 401. The damper 404 is a hydraulic damper with an adjustable damping force range of 500-1500N. The top end of the damper 404 is fixedly connected to the bottom surface of the first slider 402, and the bottom end is fixed to the bottom of the first slide groove 401. A spring 403 is sleeved on the outside of the damper 404. The spring 403 is a compression spring with an elastic coefficient of 50-100N / mm and a free length of 50-80mm. The spring 403 is sleeved on the outside of the damper 404 and its two ends are in contact with the bottom of the first slider 402 and the bottom of the first slide groove 401, respectively.

[0041] During the movement of the device, if it passes through a bumpy area, the spring 403 can be used for buffering and shock absorption. The damper 404 can consume the elastic potential energy of the spring 403 to improve the stability of the tank body 1 during movement.

[0042] like Figure 3 As shown, in a preferred embodiment, based on the above method, the lifting mechanism 6 further includes a second slide groove 601, a second slider 602, a screw 603, and a rotating assembly. The second slide groove 601 is vertically opened on the inner side of the column 3. The second slider 602 is vertically slidably arranged inside the second slide groove 601. The screw 603 is rotatably installed between the upper and lower ends of the second slide groove 601. The screw 603 is threadedly connected to the second slider 602. The second slider 602 is fixed on the outer side of the collar 5. The bottom end of the screw 603 is provided with a rotating assembly.

[0043] When the device needs to be moved, the rotating component is used to control the rotation of the screw 603. Since the screw 603 is threadedly connected to the second slider 602, the rotation of the screw 603 controls the second slider 602 to move downward. The collar 5 moves downward with the second slider 602, and the collar 5 drives multiple sets of support rods 7 to move downward.

[0044] like Figure 3As shown, in a preferred embodiment, based on the above method, the rotating assembly further includes a worm gear 604, a worm 605, and a handwheel 606. The worm gear 604 is fixed to the bottom end of the screw 603. The worm 605 is rotatably mounted inside the column 3 and meshes with the outer side of the worm gear 604. The transmission backlash of the worm gear 604 and the worm 605 is ≤0.15mm, and the contact pattern is ≥40% along the tooth height and ≥50% along the tooth length. The handwheel 606 is fixed to the end of the worm 605. When controlling the rotation of the screw 603, the handwheel 606 is held to control the rotation of the worm 605. The rotation of the worm 605 will drive the worm gear 604 to rotate, and the worm gear 604 controls the rotation of the screw 603.

[0045] like Figure 4 As shown, in a preferred embodiment, based on the above method, the unfolding mechanism 9 further includes a fixing plate 901, an upper guide groove 902, an inclined guide groove 903, a lower guide groove 904, and a guide block 905. The fixing plate 901 is vertically fixed to the bottom of the outer side of the storage tank body 1. The top of the fixing plate 901 has an upper guide groove 902, and the bottom end of the upper guide groove 902 is inclinedly provided with an inclined guide groove 903. The inclined guide groove 903 makes an angle of 30°-60° with the vertical direction. The bottom end of the guide groove 903 is provided with a lower guide groove 904. The upper guide groove 902, the inclined guide groove 903 and the lower guide groove 904 are slidably provided with guide blocks 905. The guide blocks 905 are installed on the side of the support rod 7. The upper guide groove 902 is 100-150mm long, the horizontal projection length of the inclined guide groove 903 is 80-120mm, and the horizontal length of the lower guide groove 904 is 50-80mm. The cross-section of the guide groove is rectangular, with a width of 15-25mm and a depth of 10-15mm.

[0046] In the initial state, the guide block 905 on the outside of the support rod 7 is located at the top of the upper guide groove 902. When the support rod 7 moves down, the guide block 905 moves down along the upper guide groove 902, the inclined guide groove 903 and the lower guide groove 904. After the guide block 905 passes the inclined guide groove 903, the support rod 7 unfolds outward. After the guide block 905 enters the lower guide groove 904, the unfolding angle of the support rod 7 is fixed, and then it only moves vertically downward.

[0047] like Figure 4 As shown, in a preferred embodiment, based on the above method, the guide block 905 is further cylindrical in shape and is rotatably connected to the support rod 7. The cylindrical guide block 905 can reduce the frictional resistance during movement.

[0048] Example 3

[0049] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0050] When the device is placed vertically, the support rods 7 are evenly and vertically arranged along the circumference of the tank body 1, forming a protective barrier on the outside of the tank body 1. The bottom end of the support rods 7 is located above the base 2. At this time, the tank body 1 is vertically fixed. Meanwhile, the guide block 905 on the outside of the lower support rod 7 is located at the top of the upper guide groove 902. When the tank body 1 needs to be moved, to ensure stability during movement, the handwheel 606 is used to control the rotation of the worm gear 605. The rotation of the worm gear 605 will drive the worm wheel 604 to rotate. The worm wheel 604 controls the rotation of the screw 603. Since the screw 603 is threadedly connected to the second slider 602, the rotation of the screw 603 controls the rotation of the second slider. As block 602 moves downward, collar 5 moves downward simultaneously with the second slider 602. Collar 5 drives multiple sets of support rods 7 to move downward. As the support rods 7 move downward, guide block 905 moves downward along upper guide groove 902, inclined guide groove 903 and lower guide groove 904. After guide block 905 passes through inclined guide groove 903, support rod 7 unfolds outward. After guide block 905 enters the lower guide groove 904, the unfolding angle of support rod 7 is fixed, and then it moves only vertically downward until caster 8 contacts the ground and lifts base 2 off the ground. Then the device is pushed to move, and during the movement, spring 403 is used for buffering and shock absorption to improve the stability of the tank body 1 when it moves.

[0051] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
