Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a liquid medicine storage tank with anti-pollution function. Background Technology

[0002] As a key piece of equipment in the pharmaceutical industry, the anti-contamination performance of pharmaceutical liquid storage tanks directly affects the quality and safety of drugs. During the production, storage and transportation of drugs, pharmaceutical liquids are easily contaminated by external environmental factors, operational contact and other factors. Therefore, the development of storage devices with efficient anti-contamination functions has important application value.

[0003] In the prior art, common liquid medicine storage tanks usually adopt a fixed tank structure, which is sealed by a sealing cap and relies on a manual valve to control the flow of liquid medicine. Such devices mostly achieve liquid medicine flow through gravity or simple mechanical structures, such as one-way valves or manual flow adjustment devices. Some designs also reduce the risk of contamination by adding multiple layers of sealing rings or filter components.

[0004] The quantitative control accuracy of existing medicine liquid storage tanks is low, and frequent manual operation when adjusting the tank position or pouring the medicine liquid can easily lead to seal failure or intrusion of external contaminants. This problem is particularly prominent in scenarios that require high-precision quantitative output or frequent adjustment of the tank angle, affecting the purity and storage stability of the medicine liquid. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a medicine storage tank with anti-pollution function, which aims to improve the problem of easy sealing failure or external contaminant intrusion when taking medicine.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a medicine storage tank with anti-pollution function, including a frame, a connecting rod is provided inside the frame, a tank body is provided at one end of the connecting rod, one side of the outer wall of the tank body is rotatably connected to the outer wall of the frame, a metering component is provided on the lower surface of the tank body, and an adjustment component is provided on the outer wall of the connecting rod.

[0007] The metering component includes a cylinder body, which is fixedly connected to the lower surface of the tank. Inside the cylinder body, there is a feed valve and a discharge valve. The feed valve and the discharge valve have the same structure. Inside the discharge valve, there is a connecting ring. Inside the connecting ring, there is a slide rod. One end of the slide rod is fixedly connected to a valve core. A connecting block is fixedly connected to the lower surface of the tank body. A piston is fixedly connected to the inner wall of the connecting block. The output end of the piston is slidably connected inside the cylinder body.

[0008] Furthermore, the adjustment assembly includes a first spur gear, one side of which is fixedly connected to the outer wall of the frame. A second spur gear is sleeved on the outer wall of the first connecting rod, and the first spur gear and the second spur gear mesh with each other. A handwheel is fixedly connected to one end of the first connecting rod, and a second spring is sleeved on the outer wall of the first connecting rod.

[0009] Furthermore, one end of the second spring is fixedly connected to the inside of the second spur gear, and the other end of the second spring is fixedly connected to the outer wall of the tank.

[0010] Furthermore, a spring is fitted on the outer wall of the slide bar, and a discharge nozzle is fixedly connected inside the cylinder.

[0011] Furthermore, one end of the spring is fixedly connected to one side of the outer wall of the connecting ring, and the other end of the spring is fixedly connected to one side of the outer wall of the valve core.

[0012] Furthermore, a connecting rod 2 is fixedly connected to the outer wall of the tank, and a sealing cap is installed on the top of the tank.

[0013] Furthermore, a bolt rod is threaded onto the inner wall of the connecting rod 2, and a bolt head is fixedly connected to one end of the bolt rod.

[0014] Furthermore, the bolt rod is located inside the sealing cover, and the bolt head is located inside the sealing cover.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the piston retracts, allowing the liquid medicine to enter the cylinder from below the tank. When the valve core of the discharge valve is reset under the action of the spring, the piston pushes the liquid medicine to be discharged quantitatively from the discharge nozzle. The automatic reset mechanism of the valve core and the spring can prevent liquid medicine residue or leakage. At the same time, the linkage design of the piston and the connecting block further improves the discharge stability, thereby reducing the risk of pollution caused by operating errors or valve failure.

[0017] In this invention, the adjustment component drives the connecting rod to rotate by turning the handwheel, which in turn drives the second flat gear to rotate. The meshing of the first flat gear and the second flat gear causes the tank to rotate around the frame. After the handwheel is released, the second spring presses the second flat gear onto the first flat gear through its elastic force, thus fixing the angle. This design reduces the steps of frequent manual adjustment, avoids seal wear or external contaminant intrusion caused by repeated operation, and significantly improves the anti-pollution performance.

[0026] 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.

[0027] Reference Figures 1-3This utility model provides an embodiment of a medicine storage tank with anti-pollution function, including a frame 1. A connecting rod 14 is installed inside the frame 1, and a tank body 2 is installed at one end of the connecting rod 14. One side of the outer wall of the tank body 2 is rotatably connected to the outer wall of the frame 1. Through this rotatable connection design, the tilt angle of the tank body 2 can be flexibly adjusted around the frame 1, facilitating the input or pouring of the medicine. A metering component is installed on the lower surface of the tank body 2, and an adjusting component is installed on the outer wall of the connecting rod 14. The metering component includes a cylinder 4, which is fixedly connected to the lower surface of the tank 2. An inlet valve 5 and an outlet valve 6 are installed inside the cylinder 4. The inlet valve 5 and the outlet valve 6 have the same structure. This dual-valve design ensures unidirectional flow of the medicine, avoiding backflow contamination. A connecting ring 7 is fixedly connected inside the outlet valve 6. The connecting ring 7 has a... A sliding rod 8 is provided, with a valve core 9 fixedly connected to one end of the sliding rod 8. The valve core 9 is linked with the sliding rod 8, and the valve automatically seals through spring reset to prevent leakage of medicine. A connecting block 12 is fixedly connected to the lower surface of the tank body 2, and a piston 13 is fixedly connected to the inner wall of the connecting block 12. The output end of the piston 13 is slidably connected to the inside of the cylinder body 4. The reciprocating motion of the piston 13 creates negative or positive pressure in the cylinder body 4, driving the medicine to be accurately drawn in or discharged. A spring 10 is sleeved on the outer wall of the sliding rod 8, and a discharge nozzle 11 is fixedly connected to the inside of the cylinder body 4. One end of the spring 10 is fixedly connected to one side of the outer wall of the connecting ring 7, and the other end of the spring 10 is fixedly connected to one side of the outer wall of the valve core 9. The elastic force of the spring 10 ensures that the valve core 9 quickly resets, blocking the flow path of the medicine and effectively preventing the intrusion of residues or external contaminants.

[0028] Reference Figures 1-6 The adjustment assembly includes a first spur gear 15, one side of which is fixedly connected to the outer wall of the frame 1. A second spur gear 16 is sleeved on the outer wall of a first connecting rod 14. One side of the outer wall of the first spur gear 15 is fixedly connected to the outer wall of the frame 1. The first spur gear 15 and the second spur gear 16 mesh with each other. The gear meshing structure drives the first connecting rod 14 to rotate via a handwheel 21, causing the tank 2 to rotate around the frame 1, thereby achieving stepless adjustment of the tilt angle to meet the needs of different working conditions. A handwheel 21 is fixedly connected to one end of the first connecting rod 14, and a second spring 17 is sleeved on the outer wall of the first connecting rod 14. One end of the second spring 17 is fixedly connected to the inside of the second spur gear 16, and the other end of the second spring 17 is fixedly connected to... On the outer wall of tank 2, the preload of spring 2 17 ensures that spur gear 2 16 and spur gear 1 15 mesh tightly, preventing tank 2 from shifting due to gravity or vibration and ensuring operational stability. Connecting rod 2 18 is fixedly connected to the outer wall of tank 2. A sealing cover 3 is installed on the top of tank 2. Bolt rod 19 is threadedly connected to the inner wall of connecting rod 2 18. Bolt head 20 is fixedly connected to one end of bolt rod 19. Bolt rod 19 is located inside sealing cover 3, and bolt head 20 is located inside sealing cover 3. By rotating bolt head 20, bolt rod 19 is driven to screw into threaded hole of connecting rod 2 18, so that sealing cover 3 and opening of tank 2 are tightly pressed together, forming multiple sealing barriers to isolate external pollutants.

[0029] Working principle: When using this anti-pollution medicine storage tank, first open the sealing cover 3 and inject the medicine into the tank body 2. Then close the sealing cover 3, rotate the bolt head 20, and drive the bolt rod 19 to screw in along the thread of the connecting rod 18, so that the sealing cover 3 tightly presses against the opening of the tank body 2, ensuring that the inside is isolated from the outside. After the medicine enters the cylinder body 4 through the connecting block 12, when the feed valve 5 is opened, the piston 13 retracts and forms a negative pressure in the cylinder body 4, and the medicine flows into the cylinder body 4 through the feed valve 5. After closing the feed valve 5, the piston 13 pushes out, and the slide rod 8 drives the valve core 9 of the discharge valve 6 to compress the spring. 10. When the discharge valve 6 is opened, the liquid medicine is accurately discharged from the discharge nozzle 11. After releasing the valve core 9, the piston 13 retracts, and the spring 10 automatically resets. The valve core 9 seals the discharge valve 6 through the cooperation of the connecting ring 7 and the slide rod 8 to prevent residue or leakage. When it is necessary to adjust the angle of the tank body 2, turn the handwheel 21 to drive the connecting rod 14 to rotate the flat gear 16. The flat gear 16 meshes with the flat gear 15 fixed on the frame 1, so that the tank body 2 rotates around the frame 1 to the required tilt angle. After releasing the handwheel 21, the spring 2 17 presses the flat gear 16 onto the flat gear 15 with elastic force to lock the position of the tank body 2 and prevent shaking from causing the sealing cover 3 to loosen.
