By setting the ultrasonic generator structure under the second screening plate, surface sludge can be effectively removed when washing quartz sand, and quartz sand accumulation on the screening plate can be prevented from affecting the discharge.
[0008] As a further embodiment of this utility model: a baffle of matching size is provided at the first discharge port, the lower end of the baffle is hinged to the lower end of the first discharge port, and a latch for fixing the baffle is provided on the upper part of the box body above the first discharge port. Through the structure of the first discharge port, the quartz sand is in a closed space when it is stirred in the box, and the latch can be opened when it is necessary to discharge, so as to facilitate discharge.
[0009] As a further embodiment of this invention, the second and third discharge ports are equipped with electromagnetic valves. The electromagnetic valves have a more enclosed structure, which can prevent water from overflowing during quartz sand washing and also facilitate material discharge.
[0010] As a further embodiment of this invention: the electromagnet is flatly embedded in the inner wall of the box, and the electromagnet is electrically connected to the outside of the box.

The second rotating shaft is horizontally arranged on the central axis of the housing, and one end of the second rotating shaft is connected to the second drive motor on the outer wall of the housing. A plurality of stirring paddles are evenly arranged along the circumference of the second rotating shaft. Through the arrangement of the second stirring device, the quartz sand is rapidly turned over during stirring and washing, thereby facilitating the thorough mixing of the quartz sand and water, accelerating the desliming of the quartz sand and removing fine impurities and dust.
[0013] As a further aspect of this invention, the mesh size of the second screening plate is smaller than the size of the quartz sand. This is to allow water to be discharged from the third outlet first, followed by the collection of the quartz sand from the second outlet, when discharge is required.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By installing an ultrasonic generator structure under the first screening plate, not only can the screening process on the first screening plate be accelerated, but the waste material on the first screening plate can also be discharged more quickly. By installing an ultrasonic generator structure under the second screening plate, surface sludge can be effectively removed during the washing of quartz sand, and the accumulation of quartz sand on the screening plate can be prevented from affecting the discharge.
[0016] Electromagnets, embedded in the inner wall of the chamber, remove magnetic impurities from the quartz sand during agitation. The first agitation device, in conjunction with the first screening plate, removes larger particles of impurities through agitation and sieving, and also agitates the quartz sand to further remove magnetic impurities. The second agitation device rapidly tumbles the quartz sand during agitation and washing, facilitating thorough mixing of the sand and water, thus accelerating desliming and removing fine impurities and dust.
[0017] By combining an electromagnet structure, a first stirring device with a first screening plate, a second stirring device, and an ultrasonic generator structure under the screening plate, multi-stage impurity removal integrating vibration screening, water washing, and magnetic separation can be achieved.

A first discharge port 3 and a second discharge port 4 are respectively provided on the lower end of the housing 1 of the first screening plate 11 and the second screening plate 12. The three discharge ports facilitate grading and impurity removal. The first discharge port 3 is the waste outlet for removing larger particles of quartz sand, the second discharge port 4 is the outlet for filtered quartz sand, and the third discharge port 5 is the outlet for washing water.
[0026] A fixing block 10 is provided on the higher side of the bottom of the first screening plate 11 and the second screening plate 12, and an ultrasonic generator is installed inside the fixing block 10. By setting the ultrasonic generator structure under the first screening plate 11, not only can the screening of the first screening plate 11 be accelerated, but also the waste material on the first screening plate 11 can be discharged more quickly. By setting the ultrasonic generator structure under the second screening plate 12, surface sludge can be effectively removed when washing quartz sand, and quartz sand can be prevented from accumulating on the screening plate and affecting the discharge.
[0027] A baffle of the same size is provided at the first discharge port 3. The lower end of the baffle is hinged to the lower end of the first discharge port 3. A latch 8 for fixing the baffle is provided on the upper box 1 above the first discharge port 3. Through the structure of the first discharge port 3, the quartz sand is in a closed space when it is stirred in the box 1. When it is necessary to discharge, the latch 8 can be opened for convenient discharge.
[0028] The second discharge port 4 and the third discharge port 5 are equipped with solenoid valves. The solenoid valves have a more enclosed structure, which can prevent water from overflowing during quartz sand washing and also facilitate material discharge.
[0029] The electromagnet 15 is laid flat and embedded in the inner wall of the box 1, and the electromagnet 15 is electrically connected to the outside of the box 1. By laying flat and embedding the electromagnet 15 in the inner wall of the box 1, magnetic impurities in the quartz sand can be removed when the quartz sand is stirred in the box 1.
[0030] The first stirring device includes a first rotating shaft 13 and a first drive motor 6. The first rotating shaft 13 is vertically arranged on the central axis of the housing 1. One end of the first rotating shaft 13 is connected to the first drive motor 6 at the top of the housing 1. A plurality of stirring paddles 14 are evenly arranged along the circumference of the first rotating shaft 13. The first stirring device can be used in conjunction with the first screening plate 11 to stir and screen to remove larger particle impurities, or it can be used to stir quartz sand in conjunction with the electromagnet 15 to remove magnetic impurities in the quartz sand.

By setting up the second stirring device, the quartz sand is rapidly turned over during the stirring and washing of the quartz sand, thereby facilitating the full mixing of the quartz sand and water, and accelerating the desliming of the quartz sand and the removal of fine impurities and dust.
[0032] The mesh size of the second screening plate 12 is smaller than that of the quartz sand. The mesh size of the second screening plate 12 is smaller than that of the quartz sand so that when discharge is required, water is discharged from the third discharge port 5 first, and then the quartz sand is collected from the second discharge port 4.
[0033] In using this invention, firstly, quartz sand enters the housing 1 from the feed hopper 2. The quartz sand is stirred by the first stirring device and screened by the first screening plate 11 to remove larger particles of impurities. The electromagnet 15 attracts magnetic impurities within the stirred quartz sand. These magnetic impurities on the electromagnet 15 can discharge and fall onto the first screening plate 11, where they, along with the larger particles screened out, are collected through the first discharge port 3. Next, the water inlet valve 9 is opened, and the quartz sand screened by the first screening plate falls into the lower housing 1. In the water, the quartz sand is stirred by the second stirring device, and the ultrasonic generator installed on the second screening plate 12 removes silt and fine impurities. Finally, the water in the housing 1 is discharged through the third discharge port 5, and the quartz sand falls onto the second screening plate 12 and is collected from the second discharge port 4 by the vibration of the ultrasonic generator.
