Abstract
Description
Technical Field
[0001] This utility model relates to the field of temporary storage tank technology, and in particular to temporary storage tanks for chemical liquids. Background Technology
[0002] Chemical storage tanks play a crucial role in industrial production, particularly in circuit cleaning and related fields. During circuit cleaning, a stable supply of chemical solutions is essential to ensure effective cleaning. These storage tanks provide temporary storage for chemical solutions in circuit cleaning machines and other equipment, offering significant advantages in their design. They not only ensure the stability of the chemical solutions during storage, preventing sedimentation and other issues from affecting solution quality, but also guarantee secure connections to external pipelines, reducing the risk of leakage or unstable supply due to loose connections. This ensures the efficient and stable operation of the entire cleaning process.
[0003] In existing chemical liquid storage tank systems, there is usually a storage tank for storing the chemical liquid, with a certain amount of internal space to hold it. The tank has corresponding inlets and outlets for the input and output of the liquid. The storage tank is connected to related equipment such as circuit cleaners via pipes. Through these pipes, the chemical liquid can be smoothly transported from the storage tank to the equipment that needs to be used, supporting cleaning and other operations. The connections between these pipes and the storage tank are one of the key parts of the normal operation of the entire system. During the entire operation of the system, the chemical liquid is in a relatively static, temporary storage state within the storage tank.
[0004] However, in practical use, existing chemical solution storage tanks have significant shortcomings in terms of pipe connections. Currently, most connecting pipes are secured using threaded sleeves. After prolonged use or frequent installation and disassembly, this connection method is prone to loosening due to thread wear and mechanical vibration, leading to chemical leakage. This can affect the normal operation of the circuit cleaning machine and even cause environmental pollution and equipment corrosion, severely impacting the effectiveness and stability of chemical solution storage tanks in industrial production. Therefore, this paper proposes a chemical solution storage tank to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a chemical liquid storage tank, which aims to improve the problem that the connection between pipes is usually fixed by threaded sleeves, which can easily cause the connection between pipes to loosen after long-term use or frequent installation and disassembly.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A chemical liquid storage tank includes a storage box, an internal stirring assembly, a support frame two fixedly connected to the outer wall of the storage box, a circulation pump fixedly connected to the top of the support frame two, a single-section connecting pipe one fixedly connected to one output end of the circulation pump, the single-section connecting pipe one fixedly connected to the inside of the storage box, and a multi-section connecting pipe fixedly connected to the other end of the circulation pump, with a connecting assembly provided on the outer wall of the multi-section connecting pipe.
[0008] The connecting assembly includes a fixed tube located on the outer wall of the multi-section connecting tube. A single-section connecting tube is disposed inside the fixed tube.

Multiple springs are disposed on the outer wall of the fixed tube. One end of each spring is fixedly connected to the bottom of the baffle, and the other end of the spring is fixedly connected to the top of the fixed ring. A retaining ball is disposed on one side of the baffle. The retaining ball is slidably connected inside the fixed tube and engages with the inside of the single-section connecting tube.

[0010] The stirring assembly includes multiple Venturi tubes located inside the storage tank, and a motor is fixedly connected to the outer wall of the storage tank;
[0011] As a further description of the above technical solution:
[0012] A sealing ring is provided at the bottom of the single-section connecting pipe II, and a support ring is provided on the outer wall of the sealing ring. The outer wall of the support ring is fixedly connected to the inner wall of the fixed pipe.
[0013] As a further description of the above technical solution:
[0014] A support frame is fixedly connected to the outer wall of the storage box, and a scale plate is fixedly connected to one side of the support frame.
[0015] As a further description of the above technical solution:

[0021] As a further description of the above technical solution:
[0022] Multiple connecting plates are fixedly connected to the outer wall of the rotating shaft. Each connecting plate has multiple flow holes inside, and one side of each flow hole is fixedly connected to the outer wall of the venturi tube.
[0023] This utility model has the following beneficial effects:
[0024] In this invention, the ball engages with the internal groove of the single-section connecting pipe, and the spring ensures the accurate positioning of the ball, thereby achieving a quick connection between the multi-section connecting pipe and the single-section connecting pipe. This solves the problem that the connection between pipes is easily loosened after long-term use or frequent installation and disassembly, which is usually achieved by using threaded sleeves for connection and fixation. This enhances the stability of the connection between the temporary storage tank and the outer wall pipe of the circuit cleaning machine.

This solves the problem that chemical liquids are prone to precipitation when stored in the storage tank for a long time, and the solid and liquid in the liquid separate, thus affecting the use effect of the liquid. This enhances the storage effect of the equipment on chemical liquids. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a chemical liquid temporary storage tank, including a storage box 1. The storage box 1 is equipped with a stirring assembly. A support frame 23 is fixedly connected to the outer wall of the storage box 1. A circulation pump 4 is fixedly connected to the top of the support frame 23. A single-section connecting pipe 5 is fixedly connected to one output end of the circulation pump 4. The single-section connecting pipe 5 is fixedly connected to the inside of the storage box 1. A multi-section connecting pipe 6 is fixedly connected to the other end of the circulation pump 4. A connecting assembly is provided on the outer wall of the multi-section connecting pipe 6.
[0033] The connecting assembly includes a fixing tube 9, which is located on the outer wall of the multi-section connecting tube 6. A single-section connecting tube 16 is installed inside the fixing tube 9. A fixing ring 8 is fixedly connected to the outer wall of the multi-section connecting tube 6, with its top fixedly connected to the bottom of the fixing tube 9. A connecting ring 10, made of stainless steel for good durability, is slidably connected to the outer wall of the fixing tube 9. Multiple baffles 11, also made of stainless steel, are fixedly connected to the bottom of the connecting ring 10 to ensure its durability. Multiple springs 13 are installed on the outer wall of the fixing tube 9. One end of each spring 13 is fixedly connected to the bottom of the baffle 11, and the other end of the spring 13 is fixedly connected to the top of the fixing ring 8. A retaining ball 12 is provided on one side of the baffle 11. The retaining ball 12 is made of wear-resistant alloy to ensure its wear resistance and connection stability during repeated use. The retaining ball 12 is slidably connected inside the fixing tube 9. The retaining ball 12 is engaged with the inside of the single-section connecting tube 2 16. A sealing ring 15 is provided at the bottom of the single-section connecting tube 2 16. A support ring 14 is provided on the outer wall of the sealing ring 15. The outer wall of the support ring 14 is fixedly connected to the inner wall of the fixing tube 9.
[0034] Specifically, during operation, pressure is first applied downwards to the connecting ring 10. During the downward movement, the connecting ring 10 will cause the baffle 11 to separate from the ball clamp 12. At the same time, the movement of the connecting ring 10 will apply pressure to the spring 13. Subsequently, the single-section connecting tube 16 on the outer wall of the circuit cleaner is moved to the inner wall of the fixed tube 9. The arc surface of the outer wall of the single-section connecting tube 16 is used to squeeze the outer wall of the ball clamp 12. When the single-section connecting tube 16 moves to the top of the sealing ring 15, the groove on the outer wall of the single-section connecting tube 16 will remain parallel to the ball clamp 12. Next, the pressure of the connecting ring 10 is released, and the rebound force of the spring 13 is used to push the baffle 11 to reset. After the baffle 11 is reset, it will once again tightly adhere to the ball clamp 12, thereby pushing the ball clamp 12 to be clamped in the groove on the surface of the single-section connecting tube 16. The precise design of the slot ensures a tight fit with the ball 12, achieving stable connection between the multi-section connecting tube 6 and the single-section connecting tube 16, thus guaranteeing the high efficiency and safety of the circuit cleaning machine during use.
[0035] Reference Figure 1 and Figure 3 The stirring assembly includes multiple Venturi tubes 21 located inside the storage tank 1. A motor 17 is fixedly connected to the outer wall of the storage tank 1. A support frame 2 is fixedly connected to the outer wall of the storage tank 1, and a scale plate 3 is fixedly connected to one side of the support frame 2. A cover plate 7 is rotatably connected to the top of the storage tank 1. The cover plate 7 is made of stainless steel, possessing good corrosion resistance and sealing performance to ensure that the chemical solution does not leak. The bottom of the cover plate 7 is located inside the storage tank 1. The storage tank 1 is made of high-density polyethylene, possessing good chemical stability and impact resistance. The output end of the machine 17 is fixedly connected to a rotating shaft 18. The rotating shaft 18 is made of high-quality alloy steel and has good bending strength and wear resistance. The rotating shaft 18 is located inside the storage box 1. One end of the rotating shaft 18 is rotatably connected to a support column 19. The support column 19 is fixedly connected to the outer wall of the storage box 1. Multiple connecting plates 20 are fixedly connected to the outer wall of the rotating shaft 18. Each connecting plate 20 has multiple flow holes 22 inside. The flow holes 22 are made of special alloy material and have excellent corrosion resistance. One side of each flow hole 22 is fixedly connected to the outer wall of the venturi tube 21.
[0036] Specifically, during equipment operation, the cover plate 7 is first opened, and then the chemical solution is poured into the storage tank 1. Next, the motor 17 is started, and the output of the motor 17 drives the rotating shaft 18 to rotate. Simultaneously, the rotating shaft 18 drives the connecting plate 20 to rotate synchronously, stirring the chemical solution inside the storage tank 1. At the same time, according to Bernoulli's principle, when hydraulic pressure flows into the inner wall of the flow hole 22, which is made using precision drilling technology, the flow hole 22 reduces the liquid pressure, thereby increasing the liquid flow rate. While the connecting plate 20 rotates, it also drives the venturi tube 21 to rotate inside the chemical solution. The special shape of the venturi tube 21 changes the liquid flow field structure. At the inlet, the liquid typically enters at a relatively uniform speed. When the liquid enters the throat, due to the contraction of the pipe, the liquid is forced to gather and accelerate. This gathering effect causes the liquid molecules to be more tightly packed, the streamlines to be denser, and the liquid flow direction to be more concentrated towards the throat. After the throat, the pipe gradually expands, and the liquid undergoes a diffusion process after flowing out of the throat. During this process, part of the liquid's kinetic energy is converted into pressure energy. However, because a high flow velocity has already been achieved at the throat, the entire Venturi tube 21 system accelerates the flow of the liquid as it passes through the throat. The stirring and flow holes 22 of the connecting plate 20, along with the acceleration of the liquid flow velocity by the Venturi tube 21, enhance the stirring efficiency on the inner wall of the storage tank 1, effectively preventing sedimentation of the medicine inside the storage tank 1.
[0037] Working principle: During equipment use, first open the cover plate 7 and pour the chemical solution into the storage tank 1. Next, start the motor 17 and use the output end of the motor 17 to drive the rotating shaft 18 to rotate. While rotating, the rotating shaft 18 will drive the connecting plate 20 to rotate synchronously. The connecting plate 20 will stir the solution inside the storage tank 1. At the same time, through Bernoulli's principle, when the hydraulic pressure flows into the inner wall of the flow hole 22, the flow hole 22 will reduce the liquid pressure, thereby increasing the liquid flow rate. While rotating, the connecting plate 20 will also drive the venturi tube 21 to rotate inside the solution. The special shape of the venturi tube 21 will change the liquid flow field structure. At the inlet, the liquid usually enters at a relatively uniform speed. When the liquid enters the throat, due to the contraction of the pipe, the liquid is forced to gather and accelerate. This gathering effect makes the liquid molecules more tightly arranged, the streamlines more dense, and the liquid flow direction more concentrated towards the throat. After the throat, the pipe gradually expands, and the liquid undergoes a diffusion process after flowing out of the throat. During this process, part of the liquid's kinetic energy is converted into pressure energy. However, due to the high flow velocity already achieved at the throat, the entire Venturi tube 21 system accelerates the liquid flow as it passes through the throat. The stirring and flow holes 22 of the connecting plate 20, along with the acceleration of the liquid flow velocity by the Venturi tube 21, enhance the stirring efficiency on the inner wall of the storage tank 1, preventing sedimentation of the medicine inside the storage tank 1. Next, the connecting ring 10 is pressed down. As the connecting ring 10 moves downward, it causes the baffle 11 to separate from the ball 12 side and compresses the spring 13. Subsequently, the circuit is cleared. The single-section connecting pipe 16 on the outer wall of the washing machine moves to the inner wall of the fixed pipe 9. The arc surface of the outer wall of the single-section connecting pipe 16 is used to squeeze the outer wall of the ball 12, causing the ball 12 to slide inside the fixed pipe 9. When the single-section connecting pipe 16 moves to the top of the sealing ring 15, the groove on the outer wall of the single-section connecting pipe 16 will be parallel to the ball 12. Next, the pressing force of the connecting ring 10 is released, and the rebound force of the spring 13 is used to push the baffle 11 to reset, thereby pushing the ball 12 to be stuck in the groove on the surface of the single-section connecting pipe 16, realizing the stability of the connection between the multi-section connecting pipe 6 and the single-section connecting pipe 16. Finally, the circulating pump 4 is used to circulate the chemical liquid in the storage tank 1 and the circuit cleaning machine.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
