Ultrasonic cleaning operations

Ultrasonic bath and control cabinet model MO-572 (hereinafter – the Equipment) are intended for cleaning with the use of ultrasound products from technological pollution in aqueous solutions of technical detergents (TD), used according to indications of the technological processes of the enterprise-consumer operating  the equipment.

The equipment is made in climatic version category 4.2 according to GOST15150 and is intended for use in the following  conditions:

– ambient air temperature from 10 to 35 ° C;

– relative air humidity up to 80% at 25 ° С;

– atmospheric pressure from 84 to 106.7 kPa (from 630 to 800 mm Hg) – height above

sea ​​level not more than 1000 m.

The equipment must be operated in the premises of category D on airbags 105-3.

According to the method of protection against electric shock, the equipment complies with class I according to GOST 12.2.007.0.

The equipment produces ultrasonic cleaning products in a heated solution of TD. When an ultrasonic radiator is operating in a liquid, the effect of ultrasonic cavitations and acoustic currents that affect the surface of products immersed in liquid, destroying and removing pollution. Cleaning products produced in the tank ultrasonic. Ultrasound disconnected automatically at the end of the set time. During the cleaning cycle, but the inclusion of bubbling at a given time. The temperature of the solution is maintained by automatic near the set value. The working bath is made of stainless steel and is designed to work with non-aggressive to the main material of the tank structure – steel 12X18H10T at a temperature from plus to plus 65 ° С. When working on other temperature conditions, additional adjustment is required.

The Tank is a rectangular welded construction of rolled stainless steel sheet. From the outside it is covered with a heat and sound insulating material. Capacity through anti-vibration pads installed in the frame and fastened to it with screws. The bath has a hinged lid with a counterweight and a device for draining condensate into the working tank. To turn off ultrasound when opening the lid on the container.

The working bath has a reed switch (cover sensor), and a magnet on the cover. Thirty two ultrasonic piezoceramic emitters are built into the bottom, acoustically untied from the container gasket. A cruciform collector is placed at the bottom of the tank air diving for bubbling. The bubbling system consists of a manifold, an electromagnetic air supply valve and a filter regulator to clean the air and set the required pressure. Tubes are provided for heating the cleaning solution and temperature control. Electric heaters (heating elements) in an amount of 3 pieces with a capacity of 5 kW each and a temperature sensor tours.

To control the level of the washing solution, a liquid level sensor is provided.

To fill the tank on the right side of the bath, a DN15 pipe with a thread is provided. (G1 / 2 ”).

For discharging the waste solution from the tank, 2 pipes are provided to the sewage system G1: one for draining from the overflow pocket, the other for full draining from the tank drain and overflow connections are located on the left side of the bath.

The frame is made of a profile pipe and covered with panels. The frame and panels are made from stainless steel. For maintenance of ultrasonic emitters and electric the panels are removable. The frame has adjustable feet . Suspension for products made in the form of a basket of stainless steel bar, sheet metal and stainless welded mesh. In working position, the suspension rests on board around the perimeter of the bath. The maximum load capacity of the suspension (with a uniformly distributed load) is 300 kg.

During the operation of ultrasonic emitters in ultrasonic fluid, the effect of ultrasonic cavitation and acoustic currents occurs, which affect the surface of products immersed in liquid, destroying and removing contaminants. The bubbling device is designed to remove contaminants by exposure to air bubbles. The principle of operation of the radiator is based on the change in the linear dimensions of a piezoceramic pair of crystals in the converter when a variable voltage is applied to it Voltage.
