[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When the quartz sand raw material is put into the drying chamber, the electric heating tube is turned on by control. When the electric heating tube is turned on, it heats the water inside the drying chamber. When the water inside the drying chamber is heated, it heats the drying chamber through the heating chamber, thus heating and drying the quartz sand inside the drying chamber. When the quartz sand inside the drying chamber is heated and dried, the exhaust fan is turned on by control. When the exhaust fan is turned on, it exhausts the air and dissipates heat from the inside of the drying chamber. At the same time, the stirring motor is turned on by control. When the stirring motor is turned on, it drives the stirring shaft to rotate. When the stirring shaft rotates, it stirs the quartz sand inside the drying chamber, so that the quartz sand is heated evenly, thereby facilitating the drying of the quartz sand.

[0017] This invention also features a vibration motor that is activated when quartz sand is discharged into the screening box. When the vibration motor is activated, it works with the support spring to vibrate the screening box. When the screening box vibrates, it simultaneously drives the first and second screening screens to vibrate and screen the quartz sand discharged into the screening box, and then discharges it out through the discharge chute. This facilitates the drying and grading of the quartz sand, and avoids excessive moisture affecting the screening effect during the screening process. Attached Figure Description

Two heating chambers 7 are fixedly installed at the front and rear ends of the drying chamber 2, symmetrically distributed at the front and rear ends. An electric heating tube 8 is fixedly installed inside the heating chamber 7. A water inlet 9 is fixedly connected to the outer side of the upper end of the heating chamber 7, allowing heated water to be discharged into the heating chamber 7. A temperature and humidity sensor is fixedly installed inside the drying chamber 2. A stirring motor 10 is fixedly installed on the outer side of the middle part of the drying chamber 2. A stirring shaft 11 is fixedly installed on the inner drive shaft of the stirring motor 10, and the stirring shaft 11 is rotatably connected to the middle part of the drying chamber 2 via a rotating shaft. A stirring rod 12 is fixedly installed on the outer curved surface of the stirring shaft 11, and there are several stirring rods 12, which are symmetrically distributed in sequence on the outer curved surface of the stirring shaft 11. The lower end of the drying box 2 is fixedly connected to the feeding trough 13. The front side of the lower end of the feeding trough 13 is connected to a baffle plate 14 for blocking the inner wall of the upper end of the feeding trough 13. The outer side of the front end of the feeding trough 13 is supported and fixedly installed with a U-shaped frame 15. An electric telescopic rod 16 is fixedly installed through the middle of the U-shaped frame 15. The telescopic part of the rear end of the electric telescopic rod 16 is fixedly installed in the middle of the front end of the baffle plate 14. Limiting slide rods 17 are fixedly installed on both sides of the front end of the baffle plate 14, and the front end of the limiting slide rods 17 is connected through the U-shaped frame 15, so that the baffle plate 14 can be linearly moved and limited by the limiting slide rods 17.

[0025] The upper front side of the screening box 3 is fixedly connected to the feeding trough 18, and the opening of the feeding trough 18 is located directly below the discharging trough 13. The screening box 3 has a first screening chamber 19, a second screening chamber 20 and a third screening chamber 26. The first screening chamber 19 and the second screening chamber 20 are respectively fixedly installed with a first screening screen 21 and a second screening screen 22 in the middle. The mesh size of the first screening screen 21 is larger than that of the second screening screen 22. The first screening screen 21 and the second screening screen 22 are inclined backward. The outer sides of the first screening chamber 19, the second screening chamber 20 and the third screening chamber 26 are respectively fixedly connected to the discharge trough 23. The four corners of the lower end of the screening box 3 are fixedly supported by four springs 24, which are symmetrically distributed at the four corners of the lower end of the screening box 3. The springs 24 are fixedly installed on the upper end of the mounting base plate 1. The upper middle part of the screening box 3 is fixedly installed with a vibration motor 25.

[0026] Working principle: In use, the present invention feeds the required quartz sand raw material into the drying chamber 2 through the feed hopper 5. When the quartz sand raw material is fed into the drying chamber 2, the electric heating tube 8 is turned on by control. When the electric heating tube 8 is turned on, it heats the water inside the drying chamber 2. When the water inside the drying chamber 2 is heated, it heats the drying chamber 2 through the heating chamber 7, so that the quartz sand inside the drying chamber 2 is heated and dried. When the quartz sand inside the drying chamber 2 is heated and dried, the exhaust fan 6 is turned on by control. When the exhaust fan 6 is turned on, it exhausts the air and dissipates heat inside the drying chamber 2. At the same time, the stirring motor 10 is turned on by control. When the stirring motor 10 is turned on, it drives the stirring shaft 11 to rotate. When the stirring shaft 11 rotates, it stirs the quartz sand inside the drying chamber 2, so that the quartz sand is heated evenly, thereby achieving the function of drying the quartz sand.

[0027] After the quartz sand is dried, the electric telescopic rod 16 is retracted by controlling the operation. When the electric telescopic rod 16 retracts, it drives the baffle plate 14 to move outward in a straight line. When the baffle plate 14 moves outward in a straight line, the quartz sand inside the drying box 2 will be discharged downward into the screening box 3 along the feeding chute 13 and the feeding chute 18. When the quartz sand is discharged into the screening box 3, the vibration motor 25 is activated by controlling the operation. When the vibration motor 25 is activated, it will work with the support spring 24 to drive the screening box 3 to vibrate. When the screening box 3 vibrates, it will simultaneously drive the first screening screen 21 and the second screening screen 22 to vibrate and screen the quartz sand discharged into the screening box 3, and discharge it outward through the discharge chute 23. This facilitates the grading and screening of the quartz sand after drying, and avoids the quartz sand screening effect being affected by excessive moisture during screening.
