Description

Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene (PTFE) storage tank technology, and in particular to a combined PTFE storage tank. Background Technology

[0002] Polytetrafluoroethylene (PTFE) storage tanks are widely used in media storage scenarios in industries such as chemical, pharmaceutical, and food due to their strong corrosion resistance and excellent chemical stability. However, existing PTFE storage tanks still have many problems that need to be solved in actual use. The covers of traditional PTFE storage tanks are mostly fixed by a single bolt group or flange connection. Disassembly and assembly require tightening each bolt one by one, which is cumbersome and time-consuming. Especially when it is necessary to clean, maintain, and repair the inside of the storage tank, it greatly increases the operation time and reduces maintenance efficiency. Meanwhile, the single fixed structure lacks sufficient constraint. Under conditions such as the impact of the medium flowing inside the tank and vibration during transportation, the cover is prone to displacement and loosening. This not only affects the sealing performance of the tank but may also lead to medium leakage, causing safety hazards. Existing PTFE storage tanks struggle to balance mobility and stable operation: some tanks are equipped with casters for easy movement, but these casters are always on the ground. During static storage, medium filling / discharging, and other operations, the tank is prone to displacement or shaking due to slight external impacts or changes in the center of gravity of the medium, affecting operational stability. Other tanks use fixed outriggers for stability, but lack convenient moving structures, requiring the use of forklifts, cranes, and other equipment for transfer. This not only increases transportation costs but also reduces flexibility in narrow working areas, making it difficult to quickly move to the designated work area. Although a few tanks have attempted to be equipped with lifting casters, the structural design is complex, the lifting operation is inconvenient, or the locking effect after lifting is poor, still failing to simultaneously meet the dual requirements of "convenient mobility" and "stable operation." Therefore, we propose a modular PTFE storage tank to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a modular polytetrafluoroethylene storage tank to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A modular polytetrafluoroethylene (PTFE) storage tank includes: a tank body, a cover on one side of the tank body, placement slots on both sides of the cover, and disassembly components inside the two sets of placement slots. Each disassembly component includes: a frame, a sliding plate inside the frame, insert plates and pull rods fixedly installed on both sides of the sliding plate, the insert plates being movably inserted into the cover; an insert block fixedly installed on one side of the frame, the insert block being movably inserted into the tank body; a support at the bottom of the tank body, and a moving component inside the support. The moving component includes: a bidirectional lead screw, two sets of threaded plates threaded to the outer side of the bidirectional lead screw; connecting rods hinged to both sides of the two sets of threaded plates; a common set of rotating shafts hinged to one end of the four sets of connecting rods; short plates fixedly installed on both sides of the rotating shafts; a common set of moving plates fixedly installed at the bottom of the two sets of short plates; and four sets of casters fixedly installed at the bottom of the moving plates.

[0006] Preferably, the bidirectional lead screw is rotatably mounted on the inner walls of both sides of the bracket, and a motor is fixedly installed inside one side of the bracket, with the output shaft of the motor being fixedly connected to the bidirectional lead screw.

[0007] Preferably, the two sets of sliding plates are slidably installed inside the corresponding frames, and each set of frames is provided with a spring. The two ends of the two sets of springs are fixedly connected to the corresponding sliding plate and the inner wall of one side of the frame, respectively. The two sets of pull rods slide through to one side of the corresponding frame, and a pull plate is fixedly installed on one side of each set of pull rods.

[0008] Preferably, the two sets of frames are slidably installed inside the corresponding placement slots, and each of the two sets of placement slots is provided with a second spring. The two ends of the two sets of springs are fixedly connected to the inner wall of one side of the corresponding frame and placement slot, respectively.

[0009] Preferably, limit grooves are provided on both inner walls of the bracket, and limit plates are fixedly installed on both sides of the movable plate, with the two sets of limit plates slidably installed inside the corresponding limit grooves.

[0010] Preferably, an insulation board is provided between the inner wall and the outer wall of the storage tank body, a feed pipe is fixedly installed on the top of the storage tank body, a discharge pipe is fixedly installed on one side of the cover, and two sets of support frames are fixedly installed at the bottom of the storage tank body, with both sets of support frames fixedly installed on the top of the bracket.

[0011] In this utility model, a combined polytetrafluoroethylene storage tank is provided with a cover and a disassembly assembly. Pulling the pull plate at the end of the pull rod outward causes the pull rod to drive the sliding plate to slide within the frame and compress the spring. Simultaneously, the sliding plate drives the insert plate to be pulled out from the insertion hole of the cover, releasing the positioning restriction of the insert plate on the frame. This facilitates the quick installation and disassembly of the cover, significantly shortening the time spent on cover assembly and disassembly. It also facilitates the cleaning, maintenance, and repair of the interior of the storage tank body. Furthermore, it achieves double fixation, with the double fixation structure forming a two-way constraint, effectively preventing the cover from shifting or loosening due to factors such as impact from the medium inside the storage tank or vibration during transportation.

[0012] In this utility model, a combined polytetrafluoroethylene storage tank is provided with a support and a moving assembly. The output shaft of the motor drives a bidirectional lead screw to rotate on the inner walls of both sides of the support. When the bidirectional lead screw rotates, the two sets of threaded plates connected by the outer threads are guided by the screw threads and move towards each other along the screw axis, realizing the lifting and lowering of the casters. This makes it easy to lower the casters to move the storage tank to the designated working area, and also easy to raise the casters to make the storage tank body work stably and prevent it from shifting or shaking.

The disassembly assembly 6 includes: a frame 601; a sliding plate 602 is provided inside the frame 601; an insert plate 603 and a pull rod 604 are fixedly installed on both sides of the sliding plate 602, respectively; the insert plate 603 is movably inserted into the cover 2; and an insert block 606 is fixedly installed on one side of the frame 601, and the insert block 606 is movably inserted into the tank body. Inside the tank body 1, a support 4 is provided at the bottom. Inside the support 4, a moving component 5 is provided. The moving component 5 includes: a two-way screw 501, two sets of threaded plates 502 are threaded to the outer side of the two-way screw 501, and connecting rods 503 are hinged to both sides of the two sets of threaded plates 502. One end of the four sets of connecting rods 503 is hinged to the same set of rotating shafts 504. Short plates are fixedly installed on both sides of the rotating shafts 504. The same set of moving plates 505 is fixedly installed at the bottom of the two sets of short plates. Four sets of universal wheels 507 are fixedly installed at the bottom of the moving plates 505.

[0020] In this embodiment, the bidirectional lead screw 501 is rotatably mounted on the inner walls of both sides of the bracket 4. A motor is fixedly installed inside one side of the bracket 4, and the output shaft of the motor is fixedly connected to the bidirectional lead screw 501 to facilitate the rotation of the bidirectional lead screw 501. Two sets of sliding plates 602 are slidably installed inside the corresponding frames 601. Springs 607 are provided inside both sets of frames 601. The two ends of the two sets of springs 607 are fixedly connected to the corresponding sliding plates 602 and the inner wall of one side of the frame 601, respectively. Two sets of pull rods 604 slide through to one side of the corresponding frame 601. Pull plates 605 are fixedly installed on one side of both sets of pull rods 604 to facilitate the quick reset of the insert plate 603 and to facilitate the double fixation of the cover 2 and the tank body 1.

[0021] In this embodiment, two sets of frames 601 are slidably installed inside the corresponding placement slots. Springs 608 are provided inside both sets of placement slots. The two ends of the two sets of springs 608 are fixedly connected to the inner wall of the corresponding frame 601 and the placement slot, respectively, to facilitate the quick reset of the insert 606 and the quick installation and disassembly of the cover 2 and the tank body 1. Limiting slots are provided on both sides of the inner wall of the support 4. Limiting plates 506 are fixedly installed on both sides of the moving plate 505. The two sets of limiting plates 506 are slidably installed inside the corresponding limiting slots, to facilitate the stable up and down movement of the moving plate 505. A heat insulation plate 9 is provided between the inner wall and the outer wall of the tank body 1. A feed pipe 7 is fixedly installed on the top of the tank body 1. A discharge pipe 8 is fixedly installed on one side of the cover 2. Two sets of support frames 3 are fixedly installed on the bottom of the tank body 1. The two sets of support frames 3 are fixedly installed on the top of the support 4, to facilitate the stable operation of the tank body 1.

[0022] In this embodiment, when it is necessary to disassemble the cover 2 during use, the pull plate 605 at the end of the pull rod 604 is pulled outward. The pull rod 604 causes the slide plate 602 to slide inside the frame 601 and compress the first spring 607. Simultaneously, the slide plate 602 causes the insert plate 603 to be pulled out from the insertion hole of the cover 2, releasing the positioning restriction of the insert plate 603 on the frame 601. Continuing to pull the pull plate 605, the frame 601, under the traction of the pull rod 604, compresses the second spring 608 and slides into the placement groove. 601 drives the insert block 606 to disengage from the insertion position of the tank body 1. At this time, the connection constraint between the cover 2 and the tank body 1 is completely released, and the cover 2 can be directly removed from one side of the tank body 1, completing the disassembly of the cover 2. When it is necessary to move the tank, start the motor inside the bracket 4. The motor output shaft drives the bidirectional lead screw 501 to rotate on the inner walls of both sides of the bracket 4. When the bidirectional lead screw 501 rotates, the two sets of threaded plates 502 connected by its outer threads are guided by the lead screw threads and move along the axial direction of the lead screw. During the movement of the two sets of threaded plates 502, the four sets of connecting rods 503 hinged to both sides of the threaded plates 502 rotate synchronously and push the rotating shaft 504 downward. The rotating shaft 504 drives the moving plate 505 to slide downward along the inner wall of the support 4 through the short plates on both sides. When the moving plate 505 moves downward, the four sets of universal wheels 507 at its bottom move downward synchronously until the universal wheels 507 contact the ground and lift the support 4, causing the support 4 to detach from the ground. At this time, the storage tank can move freely through the universal wheels 507. After the storage tank moves to the target position, the motor is started in reverse. The motor drives the bidirectional screw 501 to rotate in reverse. The two sets of threaded plates 502 move in opposite directions along the screw axis until the support 4 contacts the ground again and supports the storage tank. The universal wheels 507 detach from the ground. At this time, the storage tank is stably fixed through the support 4 to avoid displacement during use. The insulation plate 9 is set between the inner wall and the outer wall of the storage tank body 1, which can effectively reduce the temperature loss of the medium inside the storage tank and ensure the stability of the medium storage environment.
