An operation method of a safe chemical experimental instrument cleaning device comprises the following steps:
step 1: spraying and cleaning, namely placing chemical experimental equipment to be cleaned in a chemical experimental equipment accommodating frame 3, placing the chemical experimental equipment accommodating frame 3 in a cleaning tank 1, and enabling the chemical experimental equipment accommodating frame 3 to be close to a liquid spraying pipe 2. The solenoid valve of the liquid outlet pipe 104 is opened so that the liquid outlet pipe 104 maintains a liquid outlet state. The booster water pump is communicated with a cleaning liquid pool containing chemical agents, the solenoid valve 405, the main solenoid valve 402 and the booster water pump are opened, and the nozzle 201 of the spray pipe 2 sprays cleaning liquid to the chemical experimental instrument in the chemical experimental instrument containing frame 3.
Because if the cleaning liquid sprayed onto the chemical experimental apparatus cannot flow away immediately in time, the fresh cleaning liquid can be prevented from continuously cleaning the chemical experimental apparatus, and the cleaning liquid flowing onto the chemical experimental apparatus is ensured to naturally flow away, the liquid outlet pipe 104 is kept in a liquid outlet state during spray cleaning.
Step 2: soaking and cleaning, closing the booster water pump, completely flowing out the cleaning liquid in the cleaning pool 1, and closing the electromagnetic valve of the liquid outlet pipe 104, so that the liquid outlet pipe 104 is kept in a closed state. The solenoid valve 405, the main solenoid valve 402 and the booster water pump are opened, the nozzle 201 of the liquid spraying pipe 2 sprays the cleaning liquid until the cleaning liquid passes through the top of the chemical experimental instrument, so that the chemical experimental instrument is completely immersed in the cleaning liquid, then the main solenoid valve 402 and the booster water pump are closed, the cleaning liquid is stopped being added, and the chemical experimental instrument is soaked and cleaned. After the soaking and cleaning are finished, the electromagnetic valve of the liquid outlet pipe 104 is opened, so that the liquid outlet pipe 104 is kept in a liquid outlet state, and the cleaning liquid in the cleaning pool 1 is completely discharged.
Example 2
On the basis of the embodiment 1, the top of the cleaning tank 1 is also hinged with three independent tank covers 6, and one side of each tank cover 6 is hinged with the top of one side of the cleaning tank body 101; the tank cover 6 comprises a tank cover body 601 with the same shape as the top of the cleaning tank 1, and a handle 602 is arranged on the other side of the tank cover body 601. When the cleaning device cleans the chemical experimental instrument, the tank cover 6 is in a closed state, so that the cleaning liquid can be prevented from splashing during spray cleaning. After the cleaning device finishes cleaning the chemical experimental instrument, the pool cover 6 is opened through the handle 602, the chemical experimental instrument containing frame 3 is taken out of the cleaning pool 1, and the cleaned chemical experimental instrument is taken out of the chemical experimental instrument containing frame 3.
Example 3
On the basis of the embodiment 1, two groups of liquid spraying pipes 2 are arranged in the cleaning tank 1, two groups of liquid control mechanisms 4 are arranged outside the cleaning tank 1, and the two groups of liquid control mechanisms 4 are respectively connected with the two groups of liquid spraying pipes 2 and used for controlling the working states of the two groups of liquid spraying pipes 2; the chemical experiment instrument holding frame 3 is arranged at a position between the two groups of liquid spraying pipes 2, and the nozzles 201 of the two groups of liquid spraying pipes 2 are arranged in opposite directions. Embodiment 3 is provided with two sets of accuse liquid mechanisms 4 and two sets of hydrojet pipe 2, can spray the washing and spray the washing on the right side to the chemical industry laboratory glassware in the chemical industry laboratory glassware holds frame 3 simultaneously, improves the spray cleaning effect of chemical industry laboratory glassware.
Example 4
In the spray cleaning and the immersion cleaning of example 1, the cleaning liquid first dissolves the contaminants on the outermost surface layer of the chemical experimental apparatus, and gradually permeates into the contaminated layer for dissolution, and in this process, a dissolution saturated layer may be gradually formed on the surface layer of the chemical experimental apparatus. The dissolved saturated layer can isolate fresh cleaning liquid from deep pollutants, prevents the cleaning liquid from continuously dissolving the deep pollutants, and has poor cleaning effect if the dissolved saturated layer cannot be destroyed and removed.
Thus, on the basis of embodiment 3, one or more ultrasonic transducers 5 are mounted on the side wall of the cleaning tank body 101 of the cleaning tank 1. The ultrasonic transducer 5 can emit ultrasonic waves which can cause the cleaning tank 1 to vibrate, and acoustic cavitation occurs due to nonlinear effects when the ultrasonic waves propagate in the cleaning liquid. The shock wave emitted when the cavitation bubbles are suddenly closed can generate thousands of atmospheric pressure around the cavitation bubbles, and the impact can be directly and repeatedly carried out on the dirt layer on the surface of the chemical experimental instrument, so that on one hand, the adsorption of dirt and the surface of the chemical experimental instrument is destroyed, and on the other hand, the dirt layer on the surface of the chemical experimental instrument is destroyed to be separated from the surface of the chemical experimental instrument and dispersed into the cleaning liquid. The ultrasonic vibration causes great vibration speed and acceleration of particles in the cleaning liquid, so that the dirt on the surface of the chemical experimental instrument is frequently and violently impacted, the dissolution of the soluble dirt is accelerated, and the cleaning effect of the cleaning liquid is enhanced.
For the dirty chemical experimental instruments, the cleaning liquid is difficult to thoroughly clean the chemical experimental instruments. When the chemical experimental instrument is soaked and cleaned, the dissolved saturated layer on the surface layer can be destroyed by utilizing the action of ultrasonic waves, new cleaning liquid reaches a deeper polluted layer to be dissolved continuously, the ultrasonic waves then break the newly formed dissolved saturated layer continuously, and the cleaning is continuously carried out until the chemical experimental instrument is cleaned.
The above detailed description of embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model as claimed, but is merely representative of selected embodiments of the utility model.
