Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning, in particular to an ultrasonic automatic cleaning machine for experimental equipment. Background Art
[0002] The quality inspection center of a granular silicon production enterprise needs to conduct daily experimental analysis on the product, including total metal impurity analysis of granular silicon, total metal impurity analysis of silicon powder, and total metal impurity analysis of seed crystals. In addition, there are a large number of experimental batches every day, so a large amount of ultrapure water is needed to rinse the experimental equipment. Flushing needs to be done manually. The number of experimental equipment includes about 100 beakers, 20 volumetric flasks, 100 spoons, 10 clamps, etc. Each experimental equipment needs to be rinsed more than 80 times. It takes about 50 seconds to rinse a test equipment, and the overall completion time is relatively long. At present, the quality inspection center is equipped with an ultrapure water machine, which produces about 20 liters of water per minute, and the water tank capacity is 350 liters. The liquid level is low. When the volume reaches 45 liters, the ultrapure water machine will alarm and shut down. The water source for the ultrapure water machine is the unified water supply from the company's desalted water station. The water supply pipeline shares a main pipeline with the other two devices. The normal water supply pressure is between 0.4 MPa and 0.5 MPa. Because the horizontal position of the water intake branch pipe of the quality inspection center is higher than the points of the other two equipment, the water supply pressure of the quality inspection center will suddenly drop to between 0.1 MPa and 0.2 MPa when other users use water. If there is a pressure drop during the peak period of ultrapure water consumption in the quality inspection center, the ultrapure water machine will not be replenished in time, and the liquid level will drop and the ultrapure water machine will shut down. It takes about 20-25 minutes to fill the ultrapure water tank before normal experimental cleaning work can be carried out.
[0003] In order not to affect the overall progress of the experiment, the Quality Inspection Center now adopts the method of using ultrapure water in stages according to the number of experiments in each professional room and the degree of intensity. Based on this method, the phenomenon of ultrapure water machine shutting down due to slow water replenishment speed will still occur. Utility Model Content

The ultrapure water is pumped into the water inlet pipe 6 by the water inlet pump 3, and then flows into the inside of the box body 1 from the bottom of both sides of the box body 1 through the two water supply pipes 2. During this period, the one-way valve 4 prevents water from flowing back, and the solenoid valve 5 controls the on and off of water;
[0027] A plurality of L-shaped drain pipes 7 are respectively inserted through the top of the side wall of the box body 1. The box body 1 is square, and there are at least four drain pipes 7, which are arranged on the four side walls of the box body 1. The inlet of the water outlet pump 8 is connected to one end of the water outlet pipe 10 through a manual valve 9, and the other end of the water outlet pipe 10 is respectively connected to the plurality of drain pipes 7. When the water level of the ultrapure water reaches at least above the drain pipe 7, the manual valve 9 is opened, and the water outlet pump 8 can pump the water inside the box body 1 out of the drain pipe 7 and the water outlet pipe 10 in turn, so that the ultrapure water in the box body 1 forms a state of continuous flow.
[0028] The frame 11 is trapezoidal, and the side walls are inclined, so as to avoid the water pipe 7. Handles 12 are fixed on both sides of the top of the frame 11, and the frame 11 is movably placed in the box 1. Experimental instruments are placed in the frame 11, and the experimental instruments are immersed in water. The two handles 12 are placed in the limiting grooves 13 at the tops of both sides of the box 1. The bottoms of the two handles 12 are fixed with limiting blocks 14 that fit the outer wall of the box 1. The horizontal movement of the handles 12 is limited by the limiting grooves 13 and the limiting blocks 14, so as to limit the movement of the frame 11 and further avoid the water pipe 7.
[0029] The ultrasonic generator 15 is provided with multiple vibration heads 15.1, which are fixed on the outer wall of the box 1. The control device 15.2 of the ultrasonic generator 15 is fixed on the bottom of the box 1.

[0030] A box cover 16 is provided on the top of the box body 1 to reduce dust pollution to the water in the box body 1 .
[0031] The water inlet pipe 6 is connected to a drain pipe 17 , and a valve 18 is provided on the drain pipe 17 . When not in use, the solenoid valve 5 is closed, the valve 18 is opened, and the water in the box 1 is discharged from the water supply pipe 2 and the drain pipe 17 .
[0032] A plurality of vertical support rods 19 are fixed to the inner wall of the frame 11, and the support rods 19 enhance the longitudinal strength of the frame 11.

The inlet of the water inlet pump 3 is connected to the ultrapure water machine to provide an ultrapure water source. The ultrapure water is pumped into the water inlet pipe 6 by the water inlet pump 3, and then flows into the box 1 from the bottom of both sides of the box 1 through two water supply pipes 2. The water level of the ultrapure water is at least above the drain pipe 7. The manual valve 9 is opened, and the water outlet pump 8 can draw the water inside the box 1 from the drain pipe 7 and the outlet pipe 10 in turn, so that the ultrapure water in the box 1 forms a state of continuous flow, and the flow of water is slowly controlled; the liquid level sensor 23 monitors the water level in the box 1. When it is lower than the bottom of the drain pipe 7, the signal is transmitted to the PLC controller 24 to control the opening of the solenoid valve 5 to increase or decrease the amount of water entering.
[0036] Advantages: The ultrasonic automatic cleaning machine of the present invention can take and put the experimental instruments in the box 1 through the frame 11, thereby improving convenience. There is flowing water in the box 1, and ultrasonic vibration is added to realize the cleaning of the experimental instruments.
[0037] The flushing of experimental equipment is carried out 10 hours in advance, which can reduce the number of times the equipment is flushed the next day and further reduce the amount of water used for flushing, so that the ultrapure water machine will not be shut down and will not affect the overall progress of the experiment.
[0038] Secondly, the flowing water inlet and outlet will adopt a small flow rate and slow flow rate. Compared with manual cleaning of experimental equipment, it will reduce the use of ultrapure water and reduce energy consumption.
