Description

Technical Field

[0001] The utility model relates to the technical field of centrifuge tube cleaning, in particular to a pure water cleaning device for centrifuge tubes. Background Technique

[0002] A centrifuge tube is a tubular sample container and an accessory of a laboratory centrifuge. The Chinese utility model patent with the application number CN202321814025.6 in the prior art proposes a centrifuge tube cleaning device. This cleaning device uses two groups of clamping blocks to hold the centrifuge tube upside down at the top of the drive box. The motor drives the turntable to rotate, causing the rotating shaft to rotate synchronously. The inner wall of the centrifuge tube is cleaned by the second brush bristles. The electric push rod drives the sliding plate to move up and down, causing the two groups of clamping blocks to drive the centrifuge tube to move up and down, so that the second brush bristles clean the upper and lower positions of the inner wall of the centrifuge tube. The outer wall of the centrifuge tube is clamped by two groups of first brush bristles. When the centrifuge tube moves up and down, the outer wall of the centrifuge tube is cleaned, enabling the device to clean the inner and outer walls of the centrifuge tube simultaneously.

[0003] However, the above prior art can only clean the centrifuge tubes fixed in an upside-down position, and the cleaning mechanism cannot follow the movement of the centrifuge tubes. Therefore, it is not suitable for continuously cleaning multiple centrifuge tubes during movement, and the cleaning efficiency is relatively low. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a pure water cleaning device for centrifuge tubes that can continuously clean multiple centrifuge tubes during movement, which is beneficial to improving the cleaning efficiency.

[0005] A pure water cleaning device for centrifuge tubes of the present utility model comprises a frame, a water receiving tank and a pure water tank. The water receiving tank is installed on the frame, and the pure water tank is located below the water receiving tank. It further comprises a conveying mechanism, a secondary frame, a plurality of driving wheels, a synchronous belt and a plurality of spray heads. The conveying mechanism is installed on the frame. The conveying mechanism is evenly provided with a plurality of clamping positions. The conveying mechanism continuously conveys the centrifuge tubes along a straight line. A water supply pump is arranged in the pure water tank. A plurality of driving wheels are installed on the secondary frame. The axes of the plurality of driving wheels are arranged vertically. The synchronous belt is sleeved on the plurality of driving wheels. The plurality of spray heads are evenly installed on the outer wall of the synchronous belt. The plurality of spray heads are arranged vertically. The plurality of spray heads are located below the conveying mechanism. One side of the synchronous belt is arranged parallel to the conveying mechanism. The plurality of spray heads on one side of the synchronous belt are respectively located directly below the clamping positions of the conveying mechanism. The water pump of the pure water tank is connected to the plurality of spray heads through pipelines. The speed at which the driving wheels drive the synchronous belt to rotate is the same as the conveying speed of the conveying mechanism. During operation, a plurality of centrifuge tubes are continuously loaded upside down onto the clamping positions of the conveying mechanism. The conveying mechanism conveys the plurality of centrifuge tubes backward. At the same time, the plurality of driving wheels drive the synchronous belt to rotate. The synchronous belt drives the plurality of spray heads to rotate. Pure water is stored in the pure water tank. The water pump in the pure water tank operates to make the plurality of spray heads spray high-pressure water streams upward. When the centrifuge tubes meet the spray heads, the water streams sprayed by the spray heads wash the interiors of the centrifuge tubes. The washing water falls into the water receiving tank for recycling. Moreover, the spray heads move synchronously with the centrifuge tubes, thereby increasing the washing time. The plurality of spray heads rotate in a cycle to continuously wash the centrifuge tubes on the frame, realizing continuous cleaning of a plurality of centrifuge tubes during the movement process, which is beneficial to improving the cleaning efficiency.

[0006] Preferably, it further comprises a plurality of solenoid valves. Solenoid valves are installed on the input ends of the plurality of spray heads. By setting the opening and closing times of the plurality of solenoid valves, it is controlled that the plurality of spray heads only open when they are directly below the centrifuge tubes, saving the consumption of pure water.

[0007] Preferably, it further comprises a plurality of toggle levers, a first baffle and a second baffle. The plurality of solenoid valves are all arranged on contact switches. Toggle levers are arranged on the contact switches. The plurality of toggle levers extend outwards from the synchronous belt. The first baffle and the second baffle are both installed on the water receiving tank. The first baffle is located at the inlet end of one side of the synchronous belt. The second baffle is located at the outlet end of one side of the synchronous belt. The plurality of toggle levers are all in contact with the first baffle and the second baffle. When the spray head enters one side of the synchronous belt, the toggle lever on it contacts the first baffle, thereby generating a signal for the contact switch of the solenoid valve on it. The solenoid valve opens according to the signal, enabling pure water to be sprayed out through the spray head. When the spray head leaves one side of the synchronous belt, the toggle lever on it contacts the second baffle, thereby generating a signal for the contact switch of the solenoid valve on it. The solenoid valve closes according to the signal, stopping the spraying of pure water, realizing water conservation.

[0008] Preferably, the water pump pipeline of the pure water tank includes a rotating head and multiple connectors. The rotating head is rotatably installed at the output end of the water outlet pipe of the water pump in the pure water tank. Multiple connectors are evenly arranged in a circle on the rotating head, and the multiple connectors are respectively connected to multiple nozzles through hoses. The water outlet pipe of the water pump in the pure water tank supplies water to the multiple nozzles through the rotating head, multiple connectors and hoses. When the multiple nozzles rotate driven by the synchronous belt, the multiple nozzles can drive the multiple connectors and the rotating head to rotate synchronously on the water outlet pipe of the water pump in the pure water tank through the hoses, thus avoiding entanglement of the hoses.

[0009] Preferably, it further includes a blower, which is installed below the conveying mechanism through a bracket and is located behind the multiple nozzles. The blower blows air on the centrifuge tube to blow off the remaining water droplets and improve the cleaning effect.

[0010] Preferably, it further includes a hot air blower, which is installed below the conveying mechanism through a bracket and is located behind the multiple blowers. The hot air blower blows hot air on the centrifuge tube to dry the centrifuge tube.

[0011] Preferably, the conveying mechanism includes multiple synchronous wheels, a driving motor, two belts and two gears. The multiple synchronous wheels are symmetrically installed on the left and right sides of the frame. The driving motor is installed on the frame, and the driving motor drives one synchronous wheel to rotate. The two belts are respectively sleeved on the multiple symmetrically arranged synchronous wheels. Multiple notches are evenly arranged on the two belts, and the multiple notches on the two belts are symmetrically arranged. The notches are the clamping positions. The two gears are respectively installed on the central shafts of the two symmetrically arranged multiple synchronous wheels, and the two gears are meshed. The multiple synchronous wheels rotate to support the two belts. The driving motor drives one synchronous wheel to rotate. The synchronous wheel drives the belt and the multiple synchronous wheels on the same side to rotate synchronously, and drives the gear on the same side to rotate. The gear meshes to drive the gear on the other side, and the gear on the other side drives the synchronous wheel on the other side to rotate, so that the two belts rotate synchronously relative to each other, and the notches between the two belts are aligned to form a clamping position to clamp the centrifuge tube, which is convenient for loading, unloading and continuously conveying the centrifuge tube, and has good practicability.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: During operation, multiple centrifuge tubes are continuously and inversely loaded onto the clamping positions of the conveying mechanism. The conveying mechanism conveys the multiple centrifuge tubes backward. At the same time, multiple driving wheels drive the synchronous belt to rotate, and the synchronous belt drives multiple nozzles to rotate. Pure water is stored in the pure water tank, and the water pump in the pure water tank operates to make the multiple nozzles spray high-pressure water streams upward. When the centrifuge tube meets the nozzle, the water stream sprayed by the nozzle flushes the inside of the centrifuge tube, and the flushing water falls into the water receiving tank for recycling. Moreover, the nozzle moves synchronously with the centrifuge tube, thereby increasing the flushing time. The multiple nozzles rotate in a cycle to continuously flush the centrifuge tubes on the frame, realizing continuous cleaning of multiple centrifuge tubes during the movement process, which is beneficial to improving the cleaning efficiency.
