The ultrasonic generator I-11 is connected below the frame of the cleaning machine through a screw. As shown in figure 8, the ultrasonic generator I-11 converts a common electric signal into a high-frequency electric signal, transmits the high-frequency electric signal to the ultrasonic transducer I-07, and generates a cavitation phenomenon through the high-frequency vibration of the ultrasonic transducer I-07 in water, so that water molecules are violently impacted to remove stains on pits of walnut shells. The ultrasonic cleaning is to utilize the cavitation, acceleration and direct current action of ultrasonic waves in liquid to directly and indirectly act on liquid and dirt, so that a dirt layer is dispersed, emulsified and stripped to achieve the purpose of cleaning. The ultrasonic wave can apply very large energy to the cleaned piece without damaging the surface of the base material, and is particularly suitable for cleaning dirt firmly attached to the foundation. The cleaning effect is closely related to the cavitation intensity generated by the ultrasonic waves in the liquid. The ultrasonic vibration is transmitted in the liquid water, and when the sound wave pressure reaches one atmospheric pressure, the power density of the ultrasonic wave is 0.35w/cm2At the moment, the sound wave pressure peak value of the ultrasonic wave transmitted in the liquid easily reaches vacuum or negative pressure, liquid molecules are pulled and cracked into a cavity, the cavity is vacuum or very close to vacuum, and when a half cycle reaches the maximum value under the signal voltage value.
The liquid molecules are crushed due to the increase of the surrounding pressure, so that the liquid molecules are violently collided to generate very large impact force to impact dirt on the surface of a cleaned object, and the phenomenon that countless fine and dense bubbles generate impact waves when being broken is called cavitation. The water tank top cover I-04 is fixed on the outer edge of the water tank I-03 through an inner hexagonal socket head cap screw.

The granular material like walnut mainly takes two types of axial flow and circumferential flow as main flows in the packing auger. The friction of the packing auger is the main reason of the circumferential movement of the particles along with the packing auger blades, the friction coefficient of the packing auger is properly increased, the circumferential movement times of the walnut shells can be prolonged, and the cleaning effect is enhanced.
The auger material selection and the structural parameter design are as follows:
1. selection of materials
The auger transmission shaft I-0804 can be made of carbon steel, alloy steel, stainless steel, gray cast iron, bronze, high polymer and other materials according to different use occasions. By considering various factors (price and performance), the hollow auger transmission shaft I-0804 made of carbon structural steel Q235(A3) is found to meet the performance requirements of strength, rigidity and the like, and the shaft heads at two ends are made of 45 steel. The auger helical blade I-0801 is made of carbon structural steel Q235(A3), so that the performance requirement of the auger can be met, and the manufacturing cost is economical and reasonable.
2. Determination of the diameter of the helical blades
The diameter of the screw blade is an important parameter of the conveying capacity, and is generally determined according to the production capacity of the screw conveyor, the type of conveyed materials, the structure and the arrangement form.
The helical blade diameter can be calculated according to equation (1):
d-helical blade diameter (m);
q is the conveying amount (t/h) of the materials;
gamma-bulk specific gravity of the Material (t/m)3)；
k is an empirical coefficient representing the comprehensive characteristics of the material;
c-correction factor of the conveying amount in the inclined upward conveying;
according to the standard requirements, the spiral diameter of the auger should be rounded according to the following series of labels:
D＝150、200、250、300、400、500、600mm
3. determination of screw pitch of screw blade of packing auger
The pitch of the blade not only determines the lead angle of the screw, but also determines the slip plane of the material running under a certain filling factor, so the size of the pitch directly influences the conveying process of the material.
The pitch of the helical blade can generally be calculated as follows:
S＝k1D (2)
in the formula: k is a radical of1The ratio of the pitch of the helix to the diameter of the helix, depending on the nature of the material, is usually k10.8 is taken.
4. Determination of rotational speed of auger
In the case of not considering the friction force, an additional material flow is provided, and the influence of the additional material flow on the walnut shell particles is not obvious before the auger reaches a certain rotating speed. When the rotating speed exceeds a certain rotating speed, the material can generate movement vertical to the conveying direction, and the movement V of the material at the moment can be decomposed into horizontal movement V1Vertical movement V2。
In the formula V1-the speed of conveyance of the material in the axial direction;
in the formula V2-the peripheral speed of the material in the radial direction;
α -helix angle;
wherein V2The length of the radius is changed, so that the materials slide relatively in the rotating process of the packing auger. Material V near the screw axis2Big V1Small, material V near the outside of the helix1Big V2Is small.
When the fluid slowly flows through a static object or the object moves in the fluid, the flowing speeds of all parts in the fluid are different, and viscous resistance exists, namely;
f＝C1v (4)
f is viscous resistance, C1V is the fluid relative velocity.
Stokes measures the viscous resistance of a spherical object when the spherical object slowly moves in a fluid, and the viscous resistance is as follows:
f＝6πηvr (5)
the above formula is called stokes formula, wherein η is the viscosity coefficient of the fluid and r is the radius of the spherical object.
