A method and device for constant temperature digital controlled ultrasonic cleaning

Abstract

The invention discloses a constant-temperature numerical-control ultrasonic cleaning method and device. The constant-temperature numerical-control ultrasonic cleaning method includes the steps that the temperature of ultrasonic liquid inside the constant-temperature numerical-control ultrasonic cleaning device is detected, when the temperature of the ultrasonic liquid is higher than a set value, a certain amount of low-temperature ultrasonic liquid is added into the constant-temperature numerical-control ultrasonic cleaning device and evenly stirred, meanwhile, a certain amount of ultrasonic liquid is discharged out of the constant-temperature numerical-control ultrasonic cleaning device, and when the temperature of the ultrasonic liquid is lower than the set value, the ultrasonic liquid is heated to the set value. By means of the operation, constant-temperature and constant-amount dynamic balance of the ultrasonic liquid in the constant-temperature numerical-control ultrasonic cleaning device is maintained so as to achieve the aim of constant-temperature ultrasonic cleaning. The constant-temperature numerical-control ultrasonic cleaning device comprises a liquid storage tank. A technological material frame (1) is arranged on the upper portion of the liquid storage tank, a liquid inlet pipe is arranged on the lateral side of the liquid storage tank, a liquid outlet pipe is arranged on the bottom face of the liquid storage tank, a temperature sensor (2) and a heater (3) are arranged inside the liquid storage tank, and a magnetic stirring apparatus (7) and an ultrasonic transducer (8) are arranged below the liquid storage tank. According to the constant-temperature numerical-control ultrasonic cleaning method and device, a refrigerating system in a traditional constant-temperature ultrasonic cleaning device is eliminated, the production cost is greatly reduced, and the size of the constant-temperature ultrasonic cleaning device is reduced.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic cleaning, in particular, the invention relates to a method and device for constant-temperature numerical control ultrasonic cleaning. Background technique [0002] At present, the ultrasonic cleaners sold on the market are generally divided into two types: conventional ultrasonic cleaners and constant temperature ultrasonic cleaners. [0003] The capacity of small conventional ultrasonic cleaners is generally 2.5L or 3L, and the price of each unit is generally about 3,000 yuan. This type of ultrasonic cleaner cannot be used for temperature control. With the progress of ultrasonic cleaning, the temperature of the ultrasonic liquid in the device will increase. It keeps increasing, and the increase is very fast, usually by 1°C every 5 minutes or so. [0004] As for the constant temperature ultrasonic cleaner, because a refrigeration system such as a condenser is added during the design, this type...

AI Technical Summary

Problems solved by technology

[0005] Obviously, although the constant temperature ultrasonic cleaner can perform constant temperature ultrasonic cleaning, due to the increase of its refrigeration system, the volume of the ultrasonic cleaner has increased sharply, and the cost has risen sharply. Compared with conventional ultrasonic cleaners, its minimum capacity has increased by nearly 4. times, and the cost has increased by nearly 10 times
