Description

Technical Field

[0001] This application relates to the field of chemical raw material storage technology, and in particular to a chemical raw material storage tank. Background Technology

[0002] Currently, chemical raw materials generally need to be sealed and stored in storage tanks after production and processing.

[0003] When chemical raw materials need to be transferred, workers need to lift heavy storage tanks for transport. During the transport process, in order to prevent chemical raw materials from leaking, the storage tanks need to be kept vertical, which is not only time-consuming and labor-intensive, but also poses safety hazards. Utility Model Content

[0004] In order to improve the problem that transporting storage tanks is not only time-consuming and labor-intensive but also poses safety hazards, this application provides a chemical raw material storage tank.

[0005] The chemical raw material storage tank provided in this application adopts the following technical solution:

[0006] A chemical raw material storage tank includes a tank body, a sealing cover, and a support frame. The sealing cover is closed on the top of the tank body, and the bottom of the tank body is provided with wheels. The support frame is connected to the bottom of the tank body along a vertical sliding rod, and the tank body is provided with a lifting mechanism for driving the support frame to rise and fall.

[0007] By adopting the above technical solution, when the tank needs to be fixed, the support frame is driven to move down through the lifting mechanism, so that the lowest point of the support frame is lower than the wheels, thereby forming a stable support for the tank and avoiding possible shaking or tipping. When the tank needs to be moved, the support frame is driven to move up through the lifting mechanism, and then the tank is moved through the wheels, which improves the problem that transporting storage tanks is not only time-consuming and labor-intensive but also poses safety hazards.

[0008] Optionally, the lifting mechanism includes a pull rod, a first connecting rod, a second connecting rod, and a slider. The bottom end of the pull rod is rotatably connected to the bottom of the tank, and the tank is provided with a locking component for locking the position of the pull rod. One end of the first connecting rod is fixedly connected to the pull rod, and the other end of the first connecting rod is hinged to the second connecting rod. The other end of the second connecting rod is hinged to the slider. The slider is vertically slidably connected to the bottom of the tank, and the slider is fixedly connected to the support frame.

[0009] By adopting the above technical solution, the bottom end of the pull rod is rotatably connected to the bottom of the tank. When it is necessary to adjust the height of the support frame, the pull rod is pulled to rotate around its connection point, which drives the first connecting rod to move accordingly. The first connecting rod is hinged to the second connecting rod, and the other end of the second connecting rod is hinged to the slider, so that the slider slides vertically along the bottom of the tank, thereby driving the support frame fixedly connected to the slider to rise and fall. In the whole process, the linkage between the components ensures the stability and reliability of the height adjustment of the support frame, and the pull rod can also serve as a handhold for the staff to pull the tank, making it more convenient and labor-saving to pull.

[0010] Optionally, the locking assembly includes a fixing frame, a plug rod, and a return spring. The fixing frame includes a connecting plate and a first side plate and a second side plate perpendicularly connected to both ends of the connecting plate. The connecting plate is fixedly connected to the tank body. The plug rod is movably inserted into the first side plate. The plug rod and the fixing frame form a limiting space for accommodating the pull rod. One end of the return spring is connected to the plug rod, and the other end of the return spring is connected to the first side plate. The return spring tends to press the plug rod against the second side plate.

[0011] By adopting the above technical solution, when it is necessary to lock the pull rod, manually pull the insert rod to overcome the elastic force of the return spring, causing the insert rod to move away from the second side plate, thereby opening the channel for the pull rod to enter the limiting space. At this time, the pull rod can be swung into the limiting space. After releasing the insert rod, the return spring drives the insert rod to return to its original position and press against the second side plate, achieving stable locking of the pull rod. If it is necessary to unlock the pull rod, simply pull the insert rod again to easily remove the pull rod. The entire process is simple and convenient to operate and can effectively fix the position of the pull rod.

[0012] Optionally, the side of the insertion rod away from the connecting plate is chamfered.

[0013] By adopting the above technical solution, the chamfer setting makes the pull rod enter the limit space more smoothly, increasing the ease of operation.

[0014] Optionally, the sealing cap is threaded onto the tank body, and a locking ring is threaded onto the outer peripheral wall of the sealing cap, which is also threaded onto the tank body.

[0015] By adopting the above technical solution, the locking ring can effectively enhance the connection strength between the sealing cap and the tank body, avoid sealing failure due to vibration or external force, and ensure the safety of the storage tank during transportation or use.

[0016] Optionally, the sealing cover is equipped with a rotating motor, and the rotating shaft of the rotating motor is connected to a rotating rod that is inserted into the tank. The rotating rod is equipped with helical blades.

[0017] By adopting the above technical solution, the chemical raw materials can be turned upside down, avoiding precipitation and clumping of chemical raw materials during long-term storage and improving storage stability.

[0018] Optionally, a first gear is coaxially connected to the rotating rod, and an internal gear ring is coaxially connected inside the sealing cover; an annular groove is provided on the inner wall of the sealing cover, and a stirring rod is movably engaged in the annular groove. The stirring rod is provided with stirring blades, and a second gear is coaxially connected to the stirring rod, which meshes with both the first gear and the internal gear ring.

[0019] By adopting the above technical solution, when the rotating motor drives the rotating rod to rotate, the first gear rotates accordingly. Since the second gear meshes with both the first gear and the internal gear ring, it rotates under the drive of the first gear, thereby driving the stirring rod to rotate and causing the stirring blades to stir the chemical raw materials. Simultaneously, the second gear is also subjected to the reaction force of the stationary internal gear ring, causing the stirring rod to move in a circular motion along the annular groove. This achieves a combined motion of the stirring blades within the tank, enhancing the stirring effect and improving the uniformity of the chemical raw material mixing.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. By installing wheels and support frames at the bottom of the tank and equipping it with a lifting mechanism, the tank can be quickly switched between fixed and mobile states. The operation is simple and convenient, improving the problem that moving storage tanks is not only time-consuming and laborious but also poses safety hazards.

[0022] 2. The coordinated arrangement of the pull rod, the first connecting rod, the second connecting rod, and the slider enables a stable and reliable height adjustment function for the support frame. The structure is relatively simple and easy to use. Furthermore, the pull rod can also serve as a handhold for workers to pull the tank, making it more convenient and labor-saving to pull.

[0023] 3. The matching arrangement of the first gear, internal gear ring, second gear and stirring rod, and the compound motion of the stirring blades in the tank enhance the stirring effect and improve the uniformity of chemical raw material mixing. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a chemical raw material storage tank. (Refer to...) Figure 1-2 The chemical raw material storage tank includes a tank body 1, a sealing cover 2, and a support frame 3. The tank body 1 has a feed inlet 11 at the top, and the sealing cover 2 is threadedly connected to the feed inlet 11. The sealing cover 2 also has a stirring mechanism 4. The tank body 1 has multiple wheels 5 at the bottom, which are omnidirectional wheels. The support frame 3 has multiple limiting rods 12 welded vertically to its bottom. The support frame 3 slides vertically onto each limiting rod 12. The tank body 1 has a lifting mechanism 6 for driving the support frame 3 to rise and fall.

[0031] The lifting mechanism 6 drives the support frame 3 to move downwards until its lowest point is below the wheel 5, at which point the wheel 5 is completely off the ground, thus achieving stable support and fixation of the tank 1 by the support frame 3. When the support frame 3 rises to its highest position, the wheel 5 contacts the ground, allowing the tank 1 to be moved easily by the wheel 5, thus improving the problem of time-consuming, labor-intensive, and safety-hazardous handling of storage tanks. In addition, the stirring mechanism 4 can stir the chemical raw materials stored in the tank 1, improving the uniformity of the chemical mixture.

[0032] The lifting mechanism 6 includes a pull rod 61, a first connecting rod 62, a second connecting rod 63, and a slider 64. The bottom end of the pull rod 61 is rotatably connected to the bottom of the tank 1 via a pin 65. A handle 66 is provided at the upper end of the pull rod 61 for easy manual operation. One end of the first connecting rod 62 is welded and fixed to the pull rod 61, and the other end is rotatably connected to the second connecting rod 63. The other end of the second connecting rod 63 is rotatably connected to the slider 64, which is fixedly connected to the support frame 3. When it is necessary to move the tank 1, pulling the pull rod 61 downwards causes the first connecting rod 62 to rotate around the pin 65, which in turn causes the second connecting rod 63 to swing, thereby moving the slider 64 up and down, and consequently, the support frame 3 connected to the slider 64. Furthermore, the handle 66 on the pull rod 61 can also serve as a handhold for the operator to pull the tank 1, making pulling more convenient and effortless.

[0033] Reference Figure 3 When the tank 1 does not need to move, a locking assembly 7 is provided to lock the position of the pull rod 61 in order to further optimize the stability of the lifting mechanism 6. The locking assembly 7 includes a fixing frame 71, a plug rod 72, and a return spring 73. The fixing frame 71 consists of a connecting plate 711 and a first side plate 712 and a second side plate 713 vertically connected to both ends of the connecting plate 711. The connecting plate 711 is fixedly connected to the tank 1. The plug rod 72 is movably inserted into the first side plate 712. The plug rod 72 and the fixing frame 71 form a limiting space for storing the pull rod 61. The return spring 73 is sleeved on the plug rod 72. One end of the return spring 73 is connected to the plug rod 72, and the other end is connected to the first side plate 712. The return spring 73 tends to press the plug rod 72 against the second side plate 713. When locking the lever 61, manually pull the insert rod 72 to overcome the elastic force of the return spring 73, causing the insert rod 72 to move away from the second side plate 713, thereby opening the channel for the lever 61 to enter the limiting space; then swing the lever 61 to make the lever 61 lock into the limiting space. After releasing the insert rod 72, the return spring 73 drives the insert rod 72 to reset and press against the second side plate 713, achieving stable locking of the lever 61; if it is necessary to unlock the lever 61, pull the insert rod 72 again to easily remove the lever 61.

[0034] In addition, the side of the insertion rod 72 away from the connecting plate 711 is chamfered. The chamfer allows the pull rod 61 to press on the chamfer of the insertion rod 72 to drive the insertion rod 72 backward away from the second side plate 713, making it smoother when entering the limiting space and increasing the ease of operation.

[0035] Reference Figure 2To increase the strength of the connection between the sealing cap 2 and the tank body 1, a locking ring 21 is threaded onto the outer peripheral wall of the sealing cap 2, and the locking ring 21 is also threaded onto the tank body 1. This double-layer locking design of the sealing cap 2 and the locking ring 21 effectively prevents the risk of leakage caused by the loosening of a single threaded connection. A rubber sealing ring can also be installed between the sealing cap 2 and the tank body 1. The rubber sealing ring has good elasticity and can fill tiny gaps to ensure the airtightness and liquid tightness of the storage tank.

[0036] The stirring mechanism 4 includes a rotary motor 41, a rotating rod 42, a stirring rod 43, and a synchronous drive assembly. The rotary motor 41 is vertically bolted to the sealing cover 2. The rotating rod 42 is fixedly connected to the rotating shaft of the rotary motor 41 and inserted into the tank 1. The rotating rod 42 is equipped with spiral blades 44. Starting the rotary motor 41 drives the rotating rod 42 to rotate, which in turn drives the spiral blades 44 to rotate, thus agitating the chemical raw materials in the stirring tank and effectively preventing the chemical raw materials from settling and clumping during long-term storage.

[0037] The sealing cap 2 has an annular groove 22 on its inner wall. The top end of the stirring rod 43 is slidably engaged in the annular groove 22, and the stirring rod 43 is equipped with stirring blades. The synchronous drive assembly includes an internal gear ring 45, a first gear 46, and a second gear 47. The internal gear ring 45 is coaxially connected to the inner wall of the sealing cap 2, the first gear 46 is coaxially connected to the rotating rod 42, and the second gear 47 is coaxially connected to the stirring rod 43. The second gear 47 meshes with both the first gear 46 and the internal gear ring 45. When the rotating rod 42 rotates, the first gear 46 rotates accordingly. Because the second gear 47 meshes with both the first gear 46 and the internal gear ring 45, the second gear 47 rotates under the drive of the first gear 46, thereby driving the stirring rod 43 to rotate, causing the stirring blades to stir the chemical raw materials. At the same time, the second gear 47 is also subjected to the reaction force of the fixed internal gear ring 45, which causes the stirring rod 43 to make circumferential motion along the annular groove 22, realizing the compound motion of the stirring blades in the tank 1, enhancing the stirring effect and improving the uniformity of chemical raw material mixing.

[0038] The implementation principle of the chemical raw material storage tank in this embodiment is as follows: by pulling the lever 61, the support frame 3 is raised and lowered using the lever principle and the synergistic effect of the first connecting rod 62 and the second connecting rod 63. When the support frame 3 is lowered to the lowest position, the wheel 5 is completely off the ground, thus achieving the fixing function; when the support frame 3 is raised to the highest position, the wheel 5 contacts the ground, thus achieving the moving function. The entire process requires no additional tools, is simple and quick to operate, and has a simple and reliable structure, improving the problem that moving storage tanks is not only time-consuming and laborious but also poses safety hazards. The locking component 7 ensures that the lever 61 will not loosen due to external vibration or misoperation in the fixed state, thus ensuring the stability of the support frame 3. The combination design of the double-layer locking structure and the rubber sealing ring achieves multiple sealing protections for the chemical raw material storage tank, effectively preventing leakage problems. By rotating the motor 41 to drive the rotating rod 42 to rotate, combined with the gear transmission and planetary motion principle, all-round stirring of the chemical raw materials in the tank 1 is achieved. This design not only improves mixing efficiency but also avoids the problem of dead zones in traditional mixing devices, making it particularly suitable for chemical raw material storage scenarios that require thorough mixing.

[0039] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
