[0042] Workflow: the operation of the ultrasonic cleaning equipment is as follows, note one: all the electrical appliances of the present application are externally powered and are centrally controlled through the control box 4; note two: the division of A, B and C areas is as Figure 18The cleaning operation: the worker can first place the parts to be cleaned in the cleaning tank 3, so that the parts are completely immersed in the cleaning liquid, then the vibration box 2 is started by one key control of the control box 4, a plurality of vibrators arranged in an array in the vibration box 2 synchronously generate high-frequency electric signals which are rapidly converted into mechanical vibration to radiate ultrasonic waves to the cleaning liquid at a frequency of tens of thousands per second, under the action of the ultrasonic waves, dense cavitation bubbles are formed in the cleaning liquid, the cavitation bubbles are broken instantaneously to release powerful micro-jet and shock wave, which can deeply enter the blind hole, gap and recessed part of the parts, and quickly strip and disperse the particles, oxides and other impurities attached to the surface of the parts into the cleaning liquid, so that the parts are efficiently, completely and non-damagingly cleaned; the coarse filtering and cleaning operation: the low-speed motor in the low-speed motor mechanism 67 is started by the control box 4 to run, the low-speed motor drives the guide roller 65 located at the lower right to rotate stably at low speed in the clockwise direction; under the traction of the guide roller 65 at the lower right and the common stretching action of the remaining guide rollers 65 and the tensioning roller 66, the filter screen belt 69 is tensioned and synchronously displaced at low speed in the clockwise direction, at the same time, the liquid pump 71 is started to run by the control box 4, the liquid pump 71 cooperates with the shunt pipe 72, the joint 73 and the liquid suction plate 74 to make the cleaning liquid as a whole flow to the right towards the liquid suction plate 74; in the flowing process, the cleaning liquid must pass through the filter screen belt 69, the filter screen belt 69 coarsely filters the passing cleaning liquid, the particles with large particle size are intercepted and attached to the upper inclined surface area of the left part of the outer surface of the filter screen belt 69, then the filter screen belt 69 is transported to the right by the continuous low-speed displacement of the filter screen belt 69, when the filter screen belt 69 with attached impurities passes through the cleaning part 68, the brush 685 of the cleaning part 68 brushes off the large particle impurities, the brushed-off impurities fall downwards to the collection drawer 53, and the cleaned filter screen belt 69 can be continuously used for coarse filtering; through the above continuous operation, the preliminary coarse filtering of the cleaning liquid is completed, the ultrasonic cleaning equipment can automatically perform the preliminary coarse filtering of the cleaning liquid, and the automatically cleaned impurities and dirt under the filtering are collected; the pre-loading operation: the worker can pre-load and add different types and different particle sizes of filter materials, such as quartz sand particles, activated carbon particles and ceramic particles, to each filter unit 82 of the fine filtering module 8 according to the fine filtering requirement, the specific loading steps are as follows: first, the bolt at the loading cover 822 is completely removed from the loading port 8212, then the loading cover 822 is removed, then the filter material is continuously filled into the A area (i.e. the filtering area) in the shell part 821 through the loading port 8212 until the filter material is compacted and fills the entire A area, then the servo motor in the servo motor mechanism 85 is started by the control box 4, the servo motor drives the connecting shaft 84 and the base column 8251 of the dynamic partition part 825 to rotate by 60 degrees, the rotation of the base column 8251 synchronously drives each partition plate 8253 to displace in the outer shell 8211 through each guide groove 8252, and the partition plate 8253 always maintains the close fit with the inner curved surface of the outer shell 8211 through the elastic force of the elastic spring of the partition plate 8253, so that the dynamic partition part 825 always maintains the division of the space in the shell part 821;After the dynamic partitioning part 825 rotates, the filter material originally located in the A zone is pushed into the B zone (i.e., the transfer zone) as a whole, and the A zone is immediately formed into a new cavity. At this time, filter material can be added to the A zone again, and the A zone is filled again. After completion, the dynamic partitioning part 825 is controlled to rotate 60 degrees again, so that the filter material filled for the second time is also transferred to the B zone. The above method is repeated to sequentially complete the preloading of filter material in the A zone, the B zone, and the C zone. Since the space volumes of the A zone, the B zone, and the C zone increase in turn, and all the filter material is first filled in the A zone, the filter material in the A zone is tightly compacted in a small space, and an ideal fine filter layer can be formed. When the filter material is transferred to the B zone with a larger space, the gaps between the filter material increase slightly. When the filter material is finally transferred to the C zone (i.e., the cleaning zone) with the largest space, the filter material is fully loose, which facilitates subsequent airflow cleaning. During the entire process, the spatial positions of the A zone, the B zone, and the C zone remain unchanged, and the sequential transfer of the filter material between the zones is achieved only by the rotation of the dynamic partitioning part 825. Fine filtering and cleaning operation: After the preliminary coarse filtering is completed, the liquid pump 71 draws the cleaning liquid in which large particles have been filtered out through the shunt pipe 72, the connector 73, and the liquid suction plate 74, and stably transports the cleaning liquid to the filter unit 82 located on the front side of the fine filtering module 8 through the liquid delivery pipe 75. The cleaning liquid first enters the A area inside the filter unit 82, and completes the first fine filtering in the tightly packed filter material pores. Subsequently, the liquid is sequentially transferred to the next filter unit 82 through the intermediate pipe 83, and passes through the filter material of the corresponding A area again to achieve the second fine filtering. According to this process, the filtered cleaning liquid is sequentially flowed through the A areas of all the filter units 82 under the continuous action of the liquid pump 71, and is subjected to layer-by-layer interception by different types and different mesh numbers of filter materials, so that the small impurity particles are captured and retained one by one in the filter material, thereby completing deep fine filtering. The cleaning liquid purified by the double purification of coarse filtering and fine filtering is finally guided back to the cleaning bin 3 by the return pipe 9, and can be immediately put into the next round of part cleaning. When the system runs to the set period, the control box 4 automatically stops the liquid pump 71, and then starts the operation of the servo motor of the servo motor mechanism 85. The servo motor drives the connecting shaft 84 and the dynamic partitioning part 825 to rotate 60° synchronously, so that the filter material in the A area which has intercepted impurities is gradually transferred to the B area and the C area from the lower left, and the clean filter material on the right which has been cleaned in the previous stage is rotated into the A area to re-enter the fine filtering work. After the partition switching is completed, the liquid pump 71 resumes operation and fine filtering is started again. After the filter material is transferred, the control box 4 starts the air pump 861 of the air supply part 86. The air pump 861 draws external air through the air inlet filter pipe 862, sends the air into the air supply shell 864 through the air supply pipe 863, and then sprays the air upward at high speed through the evenly distributed air outlets on the top of the air supply shell 864.Strong air flow through the screen into the shell 821 C area, enhance the local liquidity, prompting the retention of small impurities in the filter material surface and pores from the filter material particles, and with the air flow downward through the screen plate 823 fall into the collection drawer 53, realize online cleaning, if further strengthen the cleaning effect, staff can external hot air supply pipeline and air filter tube 862 docking, into the C area of the gas into hot air, filter material for synchronous drying, dried filter material surface adhesion significantly reduced, impurities more easily fall off, thereby improving the cleaning efficiency, realized the ultrasonic cleaning equipment can automatically to clean the liquid filter, and can automatically to the impurities under the filter cleaning collection, solved the ultrasonic cleaning equipment to clean the liquid filter need artificial periodical to the impurities under the filter cleaning, increase the work burden at the same time also will affect the work efficiency problem.
