Description

Technical Field

[0001] This utility model relates to the field of vacuum tank technology, specifically to an auxiliary support structure for a vacuum tank. Background Technology

[0002] Vacuum tanks, as core equipment for realizing vacuum storage, reaction, or drying of materials, are widely used in industries such as chemical production, food processing, and pharmaceutical research and development. The installation process must strictly ensure precise connection with upstream and downstream equipment. The inlet, outlet, and vacuum interface of the vacuum tank must be sealed and connected to the external inlet pipe, outlet valve, and vacuum pump pipeline, respectively. At the same time, the detection instruments must be precisely aligned with the detection points on the tank.

[0003] Currently, the installation of vacuum tanks in the industry mostly relies on support plates with a fixed bottom height for support and positioning. That is, two metal support plates are fixed to the bottom of the vacuum tank by welding or bolting, and then the support plates are placed on the ground or foundation platform to complete the installation.

[0004] The problem with existing technology is that vacuum tanks are mostly supported by two bottom support plates during installation. However, the height of the support plates is mostly fixed. Since the vacuum tank needs to be precisely connected with upstream and downstream equipment such as feed pipes, discharge valves, vacuum pumps, and detection instruments, if the height of the support plate does not match the height of the interface of the supporting equipment, the two cannot be directly connected. In this case, it is necessary to customize special-shaped pipes, raised flanges and other adapters, which not only increases material costs, but also significantly reduces installation efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary support structure for a vacuum tank. This structure offers the advantages of adjustable tank height and auxiliary support, solving the problem that existing vacuum tanks are typically supported by two bottom support plates with fixed heights. Since the vacuum tank needs precise connection with upstream and downstream equipment such as inlet pipes, outlet valves, vacuum pumps, and testing instruments, a mismatch between the support plate height and the interface height of the supporting equipment prevents direct connection. This necessitates custom-made irregular pipes, raised flanges, and other adapters, increasing material costs and significantly reducing installation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary support structure for a vacuum tank, comprising a tank body and two support plates, wherein the top of the support plates is fixedly connected to the tank body, and a support mechanism is provided at the bottom of the tank body. The support mechanism includes a base, and limit boxes are fixedly connected to the left and right sides of the top of the base; A lifting assembly is provided on one side of each of the two limiting boxes, and auxiliary support assemblies are provided on the left and right sides of the lifting assembly; The bottom of the support plate passes through the limiting box and extends into the inner cavity of the limiting box, and contacts the inner wall of the limiting box.

[0007] In a preferred embodiment of this utility model, the lifting assembly includes a fixed plate and a threaded cylinder. The bottom of the fixed plate is fixedly connected to the base, and the bottom of the threaded cylinder is fixedly connected to the fixed plate. A screw is provided in the inner cavity and is threadedly connected to the screw. The top of the screw passes through the threaded cylinder and extends to the outside of the threaded cylinder, and is fixedly connected to an actuating block. The top of the actuating block is rotatably connected to the tank body.

[0008] As a preferred embodiment of this utility model, the surface of the screw is fitted with a concave plate and is rotatably connected to the concave plate via a bearing. Openings are provided at the bottom of the left and right sides of the inner wall of the concave plate.

[0009] As a preferred embodiment of this utility model, a first nut is provided at the bottom of the concave plate. The first nut is fitted onto the surface of the screw and is threadedly connected to the screw, and its bottom contacts the threaded cylinder.

[0010] As a preferred embodiment of this utility model, the auxiliary support assembly includes a connecting plate, a connecting block, and a support rod. The top of the connecting plate is fixedly connected to the tank body, and the support rod is inclined, with its two ends rotatably connected to the connecting block and the fixed plate, respectively.

[0011] In a preferred embodiment of this utility model, the support rod is located in the inner cavity of the opening, and stroke holes are provided on both the front and rear sides. Extrusion columns are fixedly connected to both the front and rear sides of the inner wall of the opening. The side of the extrusion column closest to the support rod passes through the stroke hole and extends into the inner cavity of the stroke hole, and contacts the inner wall of the stroke hole. The bottom of the connecting plate is provided with a T-shaped groove, and a T-shaped block is slidably connected to the inner cavity of the T-shaped groove. A bolt is fixedly connected to the bottom of the T-shaped block, and the connecting block is sleeved on the surface of the bolt, with its top in contact with the connecting plate.

[0012] As a preferred embodiment of this utility model, a second nut is provided at the bottom of the connecting block. The second nut is sleeved on the surface of the bolt and threadedly connected to the bolt, and its top contacts the connecting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem of existing vacuum tanks being supported by two bottom support plates during installation, where the support plate height is usually fixed. Since the vacuum tank needs to be precisely connected to upstream and downstream equipment such as inlet pipes, outlet valves, vacuum pumps, and testing instruments, if the support plate height does not match the interface height of the supporting equipment, the two cannot be directly connected. In this case, additional custom-made irregular pipes, raised flanges, and other adapters are required, which not only increases material costs but also significantly reduces installation efficiency. This utility model achieves flexible adjustment of the tank height, facilitating the connection between the vacuum tank interface and supporting equipment without the need for additional adapters, thus improving installation efficiency and providing stable auxiliary support.

[0014] 2. This utility model achieves precise adjustment and locking of tank height by setting up a lifting component. It is easy to operate and has no loosening after adjustment. It can adapt to different installation height requirements. Rotating the toggle block drives the screw to rise and fall along the threaded cylinder. The top of the screw pushes the tank to adjust the height synchronously. It can directly match the height of upstream and downstream equipment interfaces without the need for additional adapters. During the adjustment process, the concave plate can rise synchronously with the screw and drive the auxiliary support assembly to rotate through the extrusion column. After the adjustment is completed, the threaded cylinder and the screw are threaded together with trapezoidal thread, which has strong self-locking properties, ensuring that there is no risk of the tank falling after the height is adjusted. Then, the first nut is tightened to make it in close contact with the threaded cylinder, further reinforcing the height of the screw.

[0015] 3. This utility model achieves auxiliary support and angle self-adaptation of the tank by setting an auxiliary support component, distributing the weight of the tank and improving the overall load-bearing capacity. At the same time, it adapts to the angle changes during height adjustment. The support rod is inclined and its two ends are connected to the tank and the fixed plate respectively, forming a triangular stable structure, which distributes the weight of the tank to the base and improves the load-bearing capacity of the tank. When adjusting the height, the support rod rotates with the tank's rise and fall, and the T-shaped block slides along the T-shaped groove to guide and limit the support rod. Tightening the second nut can make the connecting block and the connecting plate make tight contact, thereby fixing the position of the support rod. Attached Figure Description

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0022] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides an auxiliary support structure for a vacuum tank, including a tank body 1 and two support plates 2. The top of the support plates 2 is fixedly connected to the tank body 1, and a support mechanism 3 is provided at the bottom of the tank body 1. The support mechanism 3 includes a base 31, and limit boxes 32 are fixedly connected to the left and right sides of the top of the base 31. A lifting assembly 33 is provided on one side of the two limit boxes 32 facing each other, and auxiliary support assemblies 34 are provided on the left and right sides of the lifting assembly 33. The bottom of the support plate 2 passes through the limiting box 32 and extends into the inner cavity of the limiting box 32, and contacts the inner wall of the limiting box 32.

[0023] Specifically, by setting up the support mechanism 3, the problem of the existing vacuum tanks being supported by two bottom support plates 2 during installation is solved. However, the height of the support plates 2 is mostly fixed. Since the vacuum tank needs to be precisely connected with upstream and downstream equipment such as feed pipes, discharge valves, vacuum pumps, and detection instruments, if the height of the support plate 2 does not match the height of the interface of the supporting equipment, the two cannot be directly connected. At this time, it is necessary to customize special-shaped pipes, raised flanges and other adapters, which not only increases material costs but also significantly reduces installation efficiency. The solution achieves the problem of flexibly adjusting the height of the tank body 1, which facilitates the connection between the vacuum tank interface and the supporting equipment without the need for additional adapters, thus improving installation efficiency and providing stable auxiliary support.

[0024] Furthermore, the lifting component 33 can drive the tank 1 to rise and fall vertically to match the height of the upstream and downstream equipment interfaces. During the adjustment process, the auxiliary support component 34 adaptively adjusts its angle as the tank 1 rises and falls, always maintaining an inclined support state to distribute the weight of the tank 1. The limit box 32, through its cooperation with the support plate 2, restricts the left and right and front and back displacement of the tank 1 to ensure the interface docking accuracy.

[0025] Example 2 In the second embodiment of this utility model, the lifting assembly 33 includes a fixed plate 331 and a threaded cylinder 332. The bottom of the fixed plate 331 is fixedly connected to the base 31, and the bottom of the threaded cylinder 332 is fixedly connected to the fixed plate 331. A screw 333 is provided in the inner cavity and is threadedly connected to the screw 333. The top of the screw 333 passes through the threaded cylinder 332 and extends to the outside of the threaded cylinder 332. An actuating block 334 is fixedly connected thereto, and the top of the actuating block 334 is rotatably connected to the tank body 1.

[0026] The screw 333 is fitted with a concave plate 4 and is rotatably connected to the concave plate 4 via a bearing. Openings 5 ​​are provided at the bottom of the left and right sides of the inner wall of the concave plate 4.

[0027] The bottom of the concave plate 4 is provided with a first nut 6, which is fitted onto the surface of the screw 333 and threadedly connected to the screw 333, and its bottom contacts the threaded cylinder 332.

[0028] Specifically, by setting up the lifting component 33, the height of the tank 1 can be precisely adjusted and locked. The operation is convenient and there is no loosening after adjustment. It can adapt to different installation height requirements. Rotating the toggle block 334 drives the screw 333 to rise and fall along the threaded cylinder 332. The top of the screw 333 pushes the tank 1 to adjust the height synchronously. It can directly match the height of the upstream and downstream equipment interfaces without the need for additional adapters. During the adjustment process, the concave plate 4 can rise synchronously with the screw 333 and drive the auxiliary support assembly 34 to rotate through the extrusion column 8. After the adjustment is completed, the threaded cylinder 332 and the screw 333 are threaded together with trapezoidal thread, which has strong self-locking properties, ensuring that there is no risk of falling after the height of the tank 1 is adjusted. Then, the first nut 6 is tightened to make it in close contact with the threaded cylinder 332, further reinforcing the height of the screw 333.

[0029] Furthermore, in the initial state, the bottom of the screw 333 is located at the bottom of the inner cavity of the threaded cylinder 332, and the tank 1 is at its lowest height. If it is necessary to raise the tank 1, rotate the actuating block 334. The actuating block 334 drives the screw 333 to move upward along the inner thread of the threaded cylinder 332. The top of the screw 333 pushes the tank 1 to rise synchronously. At the same time, the screw 333 drives the concave plate 4 to move upward. The extrusion column 8 in the opening 5 of the concave plate 4 contacts the auxiliary support assembly 34, pushing the auxiliary support assembly 34 to rotate around the fixed plate 331 and gradually contract to form support. When the tank 1 is raised to the target height, stop rotating the toggle block 334. At this time, the screw 333 and the trapezoidal thread of the threaded cylinder 332 are self-locked to prevent the tank 1 from falling. Then tighten the first nut 6 clockwise so that the bottom of the first nut 6 is in close contact with the top of the threaded cylinder 332, forming an axial lock on the screw 333 to prevent the screw 333 from loosening due to vibration. If it is necessary to lower the tank 1, loosen the first nut 6, and then turn the actuating block 334 counterclockwise. The screw 333 descends along the threaded cylinder 332, and the tank 1 moves down accordingly. The concave plate 4 drives the extrusion column 8 to pull the auxiliary support assembly 34 to unfold until the tank 1 is lowered to the appropriate height.

[0030] Example 3 In the third embodiment of this utility model, the auxiliary support component 34 includes a connecting plate 341, a connecting block 342, and a support rod 343. The top of the connecting plate 341 is fixedly connected to the tank body 1, and the support rod 343 is inclined and its two ends are rotatably connected to the connecting block 342 and the fixing plate 331, respectively.

[0031] The support rod 343 is located in the inner cavity of the opening 5, and stroke holes 7 are provided on both the front and rear sides. Extrusion columns 8 are fixedly connected to the front and rear sides of the inner wall of the opening 5. The side of the extrusion column 8 close to the support rod 343 passes through the stroke hole 7 and extends into the inner cavity of the stroke hole 7, and contacts the inner wall of the stroke hole 7. The bottom of the connecting plate 341 is provided with a T-shaped groove 9, and a T-shaped block 10 is slidably connected to the inner cavity of the T-shaped groove 9. A bolt 11 is fixedly connected to the bottom of the T-shaped block 10. The connecting block 342 is sleeved on the surface of the bolt 11, and its top is in contact with the connecting plate 341.

[0032] The bottom of the connecting block 342 is provided with a second nut 12, which is sleeved on the surface of the bolt 11 and threadedly connected to the bolt 11, and its top contacts the connecting block 342.

[0033] Specifically, by setting up the auxiliary support component 34, the auxiliary support and angle self-adaptation of the tank 1 are realized, the weight of the tank 1 is distributed, and the overall load-bearing capacity is improved. At the same time, it adapts to the angle changes during the height adjustment process. The support rod 343 is inclined and its two ends are connected to the tank 1 and the fixed plate 331 respectively, forming a triangular stable structure, which distributes the weight of the tank 1 to the base 31, thereby improving the load-bearing capacity of the tank 1. When adjusting the height, the support rod 343 rotates with the tank 1 as it rises and falls. The T-shaped block 10 slides along the T-shaped groove 9 to guide and limit the support rod 343. Tightening the second nut 12 can make the connecting block 342 and the connecting plate 341 in close contact, thereby fixing the position of the support rod 343.

[0034] Furthermore, when the tank 1 is raised, the connecting plate 341 rises synchronously with the tank 1, and the extrusion column 8 rises along the stroke hole 7, which pushes the support rod 343 to rotate around the pin of the fixed plate 331, and drives the connecting block 342 to rise synchronously with the connecting plate 341. The support rod 343 gradually retracts, and the T-shaped block 10 slides along the T-shaped groove 9 of the connecting plate 341 with the connecting block 342, restricting the movement trajectory of the connecting block 342. When the tank 1 is lowered to the target height, the support rod 343 retracts to a suitable angle to form a stable support. When the tank 1 descends, the connecting plate 341 drives the connecting block 342 to move downwards, the extrusion column 8 slides downwards along the stroke hole 7, and pushes the support rod 343 to rotate in the opposite direction around the pin of the fixed plate 331, gradually unfolding. The T-shaped block 10 resets along the T-shaped groove 9. After adjustment, the second nut 12 is tightened clockwise. The second nut 12 presses against the connecting block 342, so that the connecting block 342 and the connecting plate 341 fit tightly together, fixing the position of the support rod 343 and preventing vibration from causing the angle of the support rod 343 to change. Through the symmetrical auxiliary support components 34 on both sides, the weight of the tank 1 is evenly distributed to the base 31, improving the overall stability.

[0035] Working principle: When the height of tank 1 needs to be adjusted, observe the height difference between the vacuum tank interface and the upstream and downstream equipment interfaces to determine the height that tank 1 needs to be adjusted. Rotate the toggle block 334 of the lifting component 33 clockwise to drive the screw 333 to move upward along the threaded cylinder 332. The top of the screw 333 pushes the tank 1 to rise synchronously. During the rising process, the concave plate 4 moves upward with the screw 333. The extrusion column 8 in its opening 5 pushes the support rod 343 of the auxiliary support component 34 to retract. The T-shaped block 10 slides along the T-shaped groove 9 of the connecting plate 341 to ensure that the tilt angle of the support rod 343 is adaptively adjusted. Continue to rotate the toggle block 334 until the height of the interface of tank 1 is aligned with that of the matching equipment interface, and then stop rotating the toggle block 334. After the height of tank 1 is adjusted, tighten the first nut 6 of lifting assembly 33 clockwise so that the bottom of the first nut 6 is in close contact with the top of threaded cylinder 332, lock the position of screw 333 and prevent tank 1 from falling due to vibration. Subsequently, tighten the second nut 12 of the auxiliary support assembly 34 clockwise to make the connecting block 342 fit tightly with the connecting plate 341, fix the angle of the support rod 343, and ensure that the support rod 343 forms a stable triangular support structure. At this time, the auxiliary support assembly 34 distributes the weight of the tank 1 to the base 31, improving the overall support stability. After the vacuum tank is put into use, the trapezoidal thread self-locking structure of the lifting component 33 and the first nut 6 together ensure the stability of the height of the tank 1 and avoid height deviation caused by equipment vibration. The support rod 343 of the auxiliary support component 34 continuously distributes the weight of the tank 1, and the limit box 32 always restricts the lateral displacement of the tank 1. If the equipment layout needs to be adjusted later, the steps of height adjustment docking and auxiliary support locking can be repeated to flexibly change the height of the tank 1.

[0036] In summary, by setting up support mechanism 3, the height of the tank can be flexibly adjusted, facilitating the connection between the vacuum tank interface and supporting equipment without the need for additional adapters, thus improving installation efficiency and providing stable auxiliary support.
