Description
Technical Field
[0001] The utility model belongs to the technical field of reagent bottle cleaning equipment, and specifically relates to a closed ultrasonic cleaning device. Background Art
[0002] After conducting chemical experiments, a large number of glass bottles need to be cleaned, such as test tubes, micro-reaction bottles, nuclear magnetic tubes, volumetric flasks, triangular flasks, injection bottles, etc. The cleanliness of these glass bottles has an important impact on the results of experiments and tests.
[0003] The traditional way to clean glass bottles is usually to pre-clean them with detergent or tap water, then use an ultrasonic cleaner for further treatment, then rinse with pure water (deionized water), and finally let the glass bottles air dry naturally or put them in an oven for drying. The disadvantage of this cleaning method is that the procedure is relatively cumbersome, requiring a lot of manpower and time costs, and the entire cleaning process requires the use of a sink, ultrasonic cleaner, pure water machine, oven and other equipment, which takes up space.
[0004] Although there are equipment designed specifically for cleaning laboratory glass bottles on the market, there are the following shortcomings:
[0005] 1. The cleaning equipment is open, and the odor overflows greatly;

[0070] like Figure 1 and Figure 2As shown, the enclosed ultrasonic cleaning device of the utility model includes a bracket 10, a receiving barrel 20 installed on the bracket 10, and the receiving barrel 20 is connected to an exhaust unit 40 and a heating unit 70. Among them, rollers can be installed at the bottom of the bracket 10 for easy movement. The receiving barrel 20 is provided with a sealing cover 50 that can be lifted and lowered along the bracket 10, and the sealing cover 50 is connected to a placement rack 60 placed in the receiving barrel 20. The sealing cover 50 can seal the receiving barrel 20, so that a closed environment is formed in the receiving barrel 20, and the sealing cover 50 can be lifted and lowered along the bracket 10, which is easy to operate. The lifting method can be achieved by a motor-driven screw rod or a cylinder. It is a conventional technical means in this field and will not be repeated here. The rack 60 is used to place the glass bottles to be cleaned. In this embodiment, the rack 60 is provided with 4 layers of sample baskets 61. Each layer of sample baskets 61 is provided with a fixing rack (such as a test tube rack, which is a prior art and will not be described here) for fixing various types of glass bottles. The height of the sample basket 61 is adjustable, for example, the sample basket 61 is mounted on the rack 60 by means of a sliding sleeve to achieve height adjustment. The sealing cover 50 is provided with two inserted ultrasonic rods 31. Two mounting holes can be reserved on the sealing cover 50. The inserted ultrasonic rods 31 are inserted and fixed with a chuck joint. The heating unit 70 includes a heating machine 71, and a liquid inlet pipe 72 and a liquid outlet pipe 73 are connected between the heating machine 71 and the jacket 21. The heating machine 71 is a water heater, which heats water and delivers it to the jacket 21 through the liquid outlet pipe 73 (input from the bottom of the jacket 21). The heated water is filled into the jacket 21 from bottom to top, and heat exchanges with the cleaning agent in the container 20. Finally, it flows out from the liquid inlet pipe 72 and enters the heating machine 71 for further heating, and then circulates to exchange heat. The exhaust unit 40 includes a receiving tank 42 connected to the sealing cover 50 through an exhaust pipe 41. The receiving tank 42 is used to store the gas generated during the cleaning process. Because the cleaning agent is heated during the cleaning process, the present embodiment also installs a condenser 43 on the exhaust pipe 41 to cool the gas generated during the cleaning process and then discharge it. Of course, an exhaust valve 44 needs to be installed on the exhaust pipe 41, and the exhaust pipe 41 can be connected to the exhaust port opened on the sealing cover 50. In this embodiment, the cleaning agent is injected from the liquid inlet 53 of the sealing cover 50, and the inert gas is passed into the containing barrel 20 from the gas inlet 52 on the sealing cover 50. The sealing cover 50 is also provided with a sight glass port 54, through which the cleaning condition in the containing barrel 20 can be observed. The sealing cover 50 is also provided with a pressure gauge 55 for indicating the pressure in the containing barrel 20, so as to control the pressure in the containing barrel 20.
[0071] The working process of the enclosed ultrasonic cleaning device is as follows: the sealing cover 50 is electrically lifted, and the glass bottles to be cleaned are placed on the glass bottle rack of the sample basket 61 inside the storage barrel 20 and turned upside down; the upper and lower sample baskets 61 are adjusted to fix each layer of the glass bottles to be cleaned, and the top layer is fixed with a nylon mesh; the sealing cover 50 is slowly lowered and locked with the storage barrel 20; the storage barrel 20 is evacuated to a vacuum state from the air suction port 51; the cleaning solvent is sucked into the storage barrel from the liquid inlet 53, and the suction amount is 80% of the volume of the storage barrel 20; the air suction port 51 is closed, and the liquid inlet 53 is closed. Close, open the air inlet 52, fill nitrogen into the containing barrel 20, fill the containing barrel 20 to normal pressure, and open the valve on the exhaust pipe 41; turn on the heater 71 to heat the cleaning agent in the containing barrel 20; turn on the power of the inserted ultrasonic rod 31, ultrasonicate the glass bottle in the containing barrel 20, and start ultrasonic cleaning; after the cleaning is completed, open the air inlet 52, open the discharge valve 22, press out the cleaning agent in the containing barrel 20 and collect it in the designated solvent barrel; after the cleaning agent is pressed out, pass nitrogen to purge the residual cleaning agent inside; after drying, lift the sealing cover 50 and take out the glass bottle.
