[0028] Working principle: in use, the liquid separated by the liquid inlet conveying belt is transported to the immersion generating end head 44, and after the related parameters of the ultrasonic generator 4 are set and started, the conductor 47 passing through the top plate 2 is connected with the conductive rail 46, thereby realizing electrical connection and control with the generating end head 44, and when the ultrasonic generator 4 is working, the driving motor 41 can be started to drive the gear one 42 to rotate, thereby driving the gear ring one 43 to rotate, so that the generating end head 44 fixed on the gear ring one 43 can rotate in the solution, so that the solution can be uniformly subjected to ultrasonic strengthening effect to accelerate precipitation and improve the efficiency of solid-liquid separation, and the generating end head 44 can also stir the solution to further improve its uniformity. The conductive rail 46 and the conductor 47 can ensure that the generating end head 44 is electrically connected with the ultrasonic generator 4 during rotation, so as to ensure that the ultrasonic strengthening is stably and continuously carried out. The liquid in the mixed solution flows down to the partition plate 52 and the filter barrel 1 through the filter screen 51, and the precipitate is intercepted by the filter screen 51 and distributed on the upper surface of the filter screen 51. Before filtration, the electric push rod 58 is started to make the fixed ring 54 upwardly lift, thereby making the inclined part on the sealing ring 56 elastically expand under the action of the guide ring 57 to enter the accommodation groove 55, so that the fixed ring 54 moves out of the mounting groove 53, realizing the separation of the filter screen 51 and the mounting frame 5. The filter screen 51 can be easily taken down and cleaned and replaced, facilitating equipment maintenance and maintenance, being conducive to prolonging the service life of the equipment and improving the filtering effect. During installation, only the positioning ring 510 is inserted after being positioned in the positioning groove 59, and then the filter screen 51 is pressed vertically downward, so that the sealing ring 56 elastically expands to enter the accommodation groove 55 under the action of the guide ring 57, and the fixed ring 54 is smoothly clamped into the mounting groove 53, and sealing and limiting are realized under the action of the sealing ring 56, ensuring the stability of the use of the filter screen 51. When the gear ring one 43 rotates, the mounting rod 6 and the scraper 61 will rotate along the filter screen 51, scraping the precipitate off the filter screen 51 to avoid the deposition affecting the filtering efficiency. The inverted conical filter screen 51 and the scraper 61 arranged at a certain angle will make the scraped precipitate fall into the discharge outlet. Before use, the threaded sleeve one 64 can be rotated to adjust the distance between the mounting rod 6 and the filter screen 51, thereby adjusting the pressure of the mounting rod 6 on the clamping block 63 and the scraper 61, realizing the cleaning of the filter screen 51 at different pressures. The pressure can be adjusted according to the different states of the equipment to ensure effective cleaning, while avoiding damage to the filter screen 51 caused by excessive pressure. After the liquid is discharged, the servo motor 75 can drive the friction wheel 76 to rotate, and then drive the threaded sleeve 73 to rotate, and the threaded rod 72 moves downward along the guide cylinder 71, so that the precipitate is discharged from the discharge port to the space between the partition plate 52 and the bottom wall of the filter barrel 1. The gyro-type stop block 74 can guide the precipitate to fall to both sides when the precipitate falls, so as to avoid the precipitate falling directly on the protective shell 7, so as to protect the device and facilitate cleaning of the precipitate. The sealing plate 92 is driven by the electric telescopic rod 93 to slide, the discharge port 9 is opened, the gear 8 is driven by the servo motor 75 to rotate, the gear ring 81 is driven to rotate, and then the cleaning plate 83 is driven to rotate along the bottom of the filter barrel 1, so that the precipitate is scraped out from the discharge port 9. By setting the friction wheel 76 and the spring 77, when the cleaning plate 83 is cleaned, if the stop block 74 moves to the position and exceeds the threshold value of the friction wheel 76, relative sliding is realized, and damage to the equipment is avoided. It should be noted that the working principle and connection mode of the ultrasonic generator 4 are both mature technologies, and will not be described in detail here.

[0029] The technical scope of the present application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the present application, and these modifications and changes should be within the protection scope of the present application.
