Description

Technical Field

[0001] This utility model relates to the field of liquid preparation system technology, specifically to a liquid preparation system component that is easy to clean and disinfect. Background Technology

[0002] Liquid mixing system components typically refer to equipment parts used for the automatic or semi-automatic mixing, dispensing, and processing of liquid samples. These components usually include fluid pumps, valves, pipes, storage containers, controllers, sensors, and software to ensure accurate and repeatable liquid mixing. Liquids are delivered to the mixing tank via a transfer pump.

[0003] Chinese patent discloses a delivery pump assembly (authorization announcement number CN221400907U). This patented technology includes a delivery pump and a magnetic coupling. The delivery pump is configured to deliver a first medium. The isolation cover of the magnetic coupling cooperates with the housing of the delivery pump to form a first chamber accommodating the driven component of the magnetic coupling. The rotating shaft of the delivery pump passes through the housing, extends into the first chamber, and is drivenly connected to the driven component. A second chamber is provided on the housing to store an externally injected second medium, and the second chamber is adjacent to the first chamber. The temperature of the first medium is higher than the temperature of the second medium. In the delivery pump assembly provided by this disclosure, the second chamber is adjacent to the first chamber, and the temperature of the first medium is higher than the temperature of the second medium. Therefore, the second medium can effectively cool the first medium inside the first chamber, preventing the technical problem of demagnetization of the magnetic coupling due to excessively high first medium temperature. This ensures that the magnetic coupling can normally transmit the power of the motor to the delivery pump, avoiding the problem of unexpected pump shutdown.

[0004] This patented technology has the ability to stop unexpectedly during use, but it still has shortcomings in use. The impeller of the delivery pump used in the liquid preparation component comes into contact with the liquid, which means that the impeller cannot be thoroughly cleaned and disinfected after use because it is inside the pump casing. When the liquid preparation is changed, cross-contamination can easily occur. Therefore, those skilled in the art have provided a liquid preparation system component that is easy to clean and disinfect to solve the problems mentioned in the background art.

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.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] Example 1:

[0030] An easy-to-clean and disinfect liquid preparation system component includes a base 1, a mounting frame 2, a pump housing 5, an upper tank 8, and a lower tank 10. The mounting frame 2 and the lower tank 10 are provided at the upper end of the base 1. The pump housing 5 and the closing cover 4 are provided above the mounting frame 2. Nuts 18 are provided at the lower ends of the pump housing 5 and the closing cover 4. A motor 3 is provided at one end of the mounting frame 2. A bidirectional lead screw 25 is rotatably installed inside the mounting frame 2 and threadedly installed with the nut 18, with the threads on the outer wall being relatively distributed. A motor 32 is provided at one end of the pump housing 5. An impeller 21 is rotatably installed inside the pump housing 5 at the output end of the motor 32.

[0031] A slider 19 is provided at the lower end of the nut 18, and a guide rail 20 is provided on the inner wall of the lower end of the mounting frame 2. The slider 19 is slidably sleeved on the outer wall of the guide rail 20.

[0032] The pump casing 5 has an annular groove 22 at one end, and the closed cover 4 has a retaining ring 23 that is engaged inside the annular groove 22 at one end. The inner wall of the annular groove 22 is provided with a sealing gasket.

[0033] In this embodiment, the impeller 21 of the delivery pump is operated by motor 3. The threaded installation of nut 18 and double-acting screw 25, as well as the opening and closing relationship of the closed cover 4 and pump casing 5, are displayed to the outside, making it convenient for staff to thoroughly clean them. This design can greatly reduce the potential risk of cross-infection. Motor 3 12 drives the impeller 21 to rotate in the closed space inside the pump casing 5 and closed cover 4. After use, the closed cover 4 and pump casing 5 can be opened to facilitate quick adjustment and maintenance by the operator as needed.

[0034] Example 2:

[0035] An upper barrel 8 is provided above the lower barrel 10. A collar 9 is sleeved on the outer wall of the upper barrel 8. Hydraulic rods 11 with telescopic ends connected to the collar 9 are provided on both sides of the lower barrel 10.

[0036] The upper end of the upper barrel 8 is equipped with a motor 7, and the lower end of the motor 7 is equipped with a rotating shaft 15 rotatably installed inside the upper barrel 8. The outer wall of the rotating shaft 15 is equipped with stirring rods 16 arranged in a ring array.

[0037] The lower inner wall of the lower barrel 10 is provided with a funnel-shaped guide plate, and the lower end of the lower barrel 10 is provided with a discharge pipe 17, and a valve is provided inside the discharge pipe 17.

[0038] The upper barrel 8 and the lower barrel 10 are fitted together and connected, and a sealing gasket is provided on the mating surface;

[0039] A conveying pipe 6 is provided between the output end of the pump casing 5 and the input end of the upper barrel 8. Flanges 24 are provided at both ends of the conveying pipe 6 on the mating surfaces of the output end of the pump casing 5 and the input end of the upper barrel 8.

[0040] The outer wall of flange 24 is fitted with symmetrically distributed ferrules 14, and both ends of the conveying pipe 6 are provided with symmetrically distributed hydraulic rods 13 whose telescopic ends are connected to the ferrules 14;

[0041] In this embodiment, the upper tank 8 is lifted by hydraulic rod 11, thereby exposing the inside of the mixing tank to the outside world. The stirring structure and the inner wall of the mixing tank can be easily cleaned and disinfected. At the same time, the flange 24 of the delivery pipe 6 is connected and closed by the clamp 14. The bolts of the closure can be easily removed and installed during use, making assembly convenient and facilitating quick reassembly after equipment cleaning, thus shortening the maintenance, cleaning and disinfection time. It is worth noting that the delivery pipe 6 is a flexible hose with a steel wire inner layer, which can be stretched and moved.

[0042] Working principle: Motor 3 12 drives impeller 21 to rotate in the closed space inside pump casing 5 and closed cover 4. The pump casing 5 draws liquid material from the suction end and delivers it through the output end. The liquid material enters the closed space inside upper tank 8 and lower tank 10 through the delivery pipe 6. Motor 2 7 drives the rotating shaft 15 to rotate, which drives the stirring rod 16 to stir the liquid material, realizing the stirring and mixing of the liquid material in the liquid distribution system. The liquid material is transferred through the discharge pipe 17.

[0043] After the liquid is mixed, motor 3 drives the bidirectional lead screw 25 to rotate. Because of the relatively distributed threads on the outer wall of the bidirectional lead screw 25 and the sliding block 19 is slidably mounted on the guide rail 20, when the bidirectional lead screw 25 rotates, it pushes the nut 18 relative to or away from each other, causing the closed pump casing 5 and the closed cover 4 to open. The fitted retaining ring 23 is in contact with the ring groove 22, and the impeller 21 is exposed to the outside. At the same time, hydraulic rod 13 drives the sleeve 14 to move away from each other, contacting the flange 24. The two ends of the delivery pipe 6 are in contact with the output end of the pump casing 5 and the input end of the upper tank 8. The delivery pipe 6 is moved out, and hydraulic rod 11 drives the upper tank 8 to lift. The fitting relationship between the upper tank 8 and the lower tank 10 is released, and the upper tank 8 and the lower tank 10 are opened. The inside of the mixing tank composed of the upper tank 8 and the lower tank 10 is exposed to the outside, which is convenient for the staff to clean and disinfect.
