Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Example 1

Referring to fig. 1 and 2, compared with the conventional device for removing the impurities in the white oil by stirring, the device uses an air floatation method to remove suspended wax in the white oil, generates bubbles through an ultrasonic generator 13 at the bottom, and then carries the suspended wax in the process of floating up the bubbles, thereby removing the wax deposition in the white oil, and then recycling the gathered wax through a wax scooping part 2.

The concrete structure comprises: tank body 1 and wax portion 2 drag for, tank body 1 is open-top's tank-like structure and is provided with inlet tube 11 and outlet tube 12 respectively in the both sides of bottom, be provided with the multilayer on the bottom surface of tank body 1 and be the supersonic generator 13 of circumference range, wax portion 2 drag for includes carrier ring 24 and tripe 25, every tripe 25 is the bar platelike structure that the density is less than industrial white oil and the long limit of one side is provided with axis of rotation 252, the bottom of carrier ring 24 inwards protrudes the step structure that forms the bearing, all tripe 25 rotate with carrier ring 24 through axis of rotation 252 with the linear arrangement mode and be connected.

Working principle:

ultrasonic devices can generally generate air bubbles in a liquid by sound waves. This process is known as cavitation. As the ultrasonic wave propagates through the liquid, it generates pressure waves in the liquid. The high pressure phase of these waves compresses the liquid, while the low pressure phase creates a localized low pressure region. In these low pressure regions, the liquid may instantaneously vaporize, forming bubbles or cavities. In some cases, impurities may be adsorbed onto the bubbles during the flotation of the bubbles and then removed as the bubbles rise. This is the basic principle of the air-float process.

The device removes suspended wax in the white oil by an air floatation method.

1. The inlet pipe 11 is opened and the outlet pipe 12 is closed, the inside of the tank 1 is filled with industrial white oil, then the inlet pipe 11 is closed, the ultrasonic generator 13 is started, and bubbles are formed by ultrasonic waves.

2. The bubbles adsorb the suspended wax during the process of floating up inside the industrial white oil, and when reaching the highest liquid level of the industrial white oil, the bubbles break and carry the wax to the surface. The wax suspended after a period of treatment is brought to the surface entirely.

3. The operator operates the wax scooping part 2 to descend, and when entering the inside of the industrial white oil, the louver 25 floats up and stands up because the density of the louver 25 is smaller than that of the industrial white oil, so that the wax on the surface layer can pass through the gap of the louver 25.

4. The staff lifts wax portion 2, and because the white oil fluid passes the gap drive of tripe 25 this moment, tripe 25 rotates to horizontal position and forms the structure of leaking the net shape, because carrier ring 24 has inwards convex step so can not continue the rotation downwards, and the in-process of continuing the lift, wax through the air supporting gathering can be taken away by tripe 25, and white oil can flow out through the gap between the tripe 25.

5. The operator lifts up and drags for wax portion 2, will drag for wax that takes out and clear up, then the repetitive operation can be with wax clean up, then opens outlet pipe 12, discharges clean industry white oil to accomplish the work that wax was retrieved.

This device can be efficient through setting up ultrasonic generator 13 at the inside formation a large amount of bubbles of industry white oil, can adsorb at the come-up in-process of bubble and carry wax and impurity, then get up wax's that gathers impurity through the wax portion 2 of dragging for of shutter structure and get rid of, simple structure need not to use powerful motor in order to centrifuge jar body 1 to reduce the energy consumption and reduced noise and maintenance cost.
