Description

Technical Field

[0001] The invention relates to the field of cleaning and is a chemical experiment equipment storage device. Background Art

[0002] Test tubes are common reaction containers in chemical experiments, used to hold chemical reagents for small-dose chemical experiments. They are usually made of glass, which is easy to observe experimental reactions in real time because of its high transparency. At the same time, glass does not react with most reagents, thus ensuring the purity of the chemical experimental environment. After the experiment, the test tubes need to be cleaned so that they can be recycled without affecting subsequent experiments. After cleaning, the test tubes need to be properly stored to avoid damage and loss.

[0003] When a large number of test tubes need to be cleaned, cleaning equipment is often used to clean them to improve cleaning efficiency. However, the cleaned test tubes need to be taken out of the cleaning equipment one by one and placed on the storage rack one by one. This process is cumbersome and time-consuming, and requires careful operation to prevent the test tubes from being contaminated. Therefore, the existing technology has a cumbersome cleaning and storage process for test tubes after use, and it is urgent to design a chemical experiment equipment storage device that does not require the transfer of test tubes to simplify the treatment process of test tubes after use. Summary of the invention

[0004] In view of the above problems, the present invention proposes a chemical experiment equipment storage device, and the technical solution is as follows:

[0006] The rack unit includes: a fixing ring fixedly connected to the central column; a storage rack arranged on the fixing ring, on which the test tube is placed upside down, and at least three storage racks are arranged on the fixing ring; an expansion bag fixedly connected to the storage rack, the expansion bag is filled with water to expand and squeeze and tension the test tube, the expansion bag rotates relative to the test tube, and the inner wall surface of the test tube can be cleaned, and holes are arranged on the expansion bag; a connecting tube fixedly connected between the expansion bag and the central column, the connecting tube connects the expansion bag and the central column.

[0007] As a further limitation of the technical solution, at least one set of shelf units is arranged on the central column.

[0008] As a further limitation of the present technical solution, it also includes: a screw rotatably connected to the bin shell; a guide rod fixedly connected to the bin shell; a motor a fixedly connected to the bin shell, the output end of the motor a is fixed to the screw, and the motor a is controlled by the machine base; a cross frame arranged between the screw and the guide rod, the cross frame is threadedly connected to the screw, and is slidably connected to the guide rod, and the cleaning cylinder is rotatably connected to the cross frame.

[0009] As a further limitation of the technical solution, it also includes: a motor b fixedly connected to the horizontal frame, which is controlled by the base; a rotating shaft rotatably connected to the horizontal frame, and the output end of the motor b is fixed to the rotating shaft; a bevel gear a fixedly connected to the rotating shaft; a bevel gear ring fixedly connected to the top of the cleaning cylinder, and the bevel gear a is meshed with the bevel gear ring.

[0014] The beneficial effects are as follows:

[0015] The present invention uses a rack unit that can change modes to place test tubes. When the present invention is used to clean the test tubes, the position of the test tubes is stabilized by using an expansion bag to clean them, and the inner wall of the test tube is cleaned in cooperation with a cleaning cylinder that cleans the outer wall of the test tube. After the test tubes are cleaned, the racks are released from fixation so that the racks can be unfolded to assist in dehydrating the test tubes, thereby helping the test tubes to dry and clean faster. After the test tubes are dehydrated, the racks are fixed again so that the test tubes can be stored in a stable state. Therefore, the present invention achieves the effect of not needing to transfer the test tubes by combining the cleaning function and the storage function into one, thereby simplifying the processing flow of the test tubes after use and improving the convenience of use of the present invention.

A contact pattern b801 is provided on the inner wall surface of the cleaning cylinder 8. When the cleaning cylinder 8 is covered outside the storage rack 5, the contact pattern b801 on the cleaning cylinder 8 will contact the test tube 0 placed on the rack unit. Therefore, when the cleaning cylinder 8 rotates, the contact pattern b801 on the cleaning cylinder 8 can clean the outer wall surface of the test tube 0. The nozzle 9 is fixedly installed at the bottom of the chamber shell 2, and the nozzle 9 faces upward.

[0032] See also Figure 6 , Figure 7 and Figure 8 , and also includes: a bevel gear b18 fixedly mounted on the rotating shaft 15 and the center column 3, the two bevel gears b18 are meshed, so that the rotating shaft 15 can drive the center column 3 to rotate. When the center column 3 rotates, the rack 5 rotates upward relative to the center column 3 under the action of centrifugation, and its angle direction is close to the direction in which water flows under the centrifugal force, so it can accelerate the outflow of water from the test tube 0; a gasket 19 fixedly mounted on the center column 3, and six gaskets are arranged on the gasket 19. The position of each gasket corresponds to the position of each rack 5.

[0035] The test tubes 0 to be cleaned are placed on the racks 5 in sequence, and the machine base 1 is used to control the filling of water into the expansion bag 6, so that the expansion bag 6 tightens the test tube 0 without shaking; then, the motor a12 is controlled to control the cleaning cylinder 8 to move downward, and the two bevel gears b18 are disengaged, and the cleaning cylinder 8 contacts the outer wall surface of the test tube 0 placed on the rack 5. After this step is completed, the motor b14 is controlled to control the cleaning cylinder 8 to rotate, and the nozzle 9 is controlled to spray water between the test tube 0 and the cleaning cylinder 8. The contact pattern a601 on the cleaning cylinder 8 uses the water sprayed by the nozzle 9 to clean the outer wall surface of the test tube 0. At the same time, the friction between the cleaning cylinder 8 and the test tube 0 will drive the test tube 0 to rotate relative to the expansion bag 6, and the expansion bag 6 uses the water flowing out of its hole to clean the inner wall surface of the test tube 0. The inside and outside are synchronized, and the cleaning work of the test tube 0 is quickly completed;

At this time, the fixing function of the storage rack 5 is converted into a storage function, so that the test tube 0 can be neatly and stably stored.

[0037] All sewage will be discharged through the leakage hole 23 and the discharge pipe 24 to avoid sewage accumulation in the storage shell 2, so as to prevent the subsequent use and cleaning of the equipment from being affected; and when the residue on the test tube 0 involves the generation of harmful gases, when cleaning such a test tube 0, the sealing shell 22 is slid downward to close the storage shell 2, and the processor 20 is used to suck out and treat the harmful gas to prevent the leakage of harmful gases from causing harm to the operator.
