[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0022] like Figure 1-3 As shown, a quartz sand filter material grading and screening device includes a box 1, which is provided with:

[0023] A first sieve plate 2 and a second sieve plate 3 are arranged in an inclined shape in the vertical direction, and a first discharge port 12, a second discharge port 13 and a third discharge port 14 are opened on the box body 1. The first discharge port 12 is located at the lower end of the first sieve plate 2, the second discharge port 13 is located at the lower end of the second sieve plate 3, and the third discharge port 14 is located at the bottom of the box body 1;

[0024] The inclined baffle plate 4 is arranged in an inclined shape between the first screen plate 2 and the second screen plate 3 to support the quartz sand falling from the first screen plate 2 , and the lower end of the inclined baffle plate 4 faces the higher end of the second screen plate 3 .

[0025] Specifically, Figure 1As shown, a first screen plate 2 and a second screen plate 3 are arranged in the box body 1, the first screen plate 2 is located above the second screen plate 3, and the lower end of the first screen plate 2 is located vertically above the higher end of the second screen plate 3, the upper surface of the inclined baffle 4 is a supporting surface, and a pouring groove 11 is also arranged on the top of the box body 1. When the quartz sand raw material is poured into the box body 1 from the pouring groove 11, the quartz sand raw material moves along the upper surface of the first screen plate 2 from the higher end to the lower end. At this time, the larger quartz sand particles roll out from the first discharge port 12, while the particles Slightly smaller quartz sand particles pass through the first screening plate 2 and fall onto the inclined baffle 4. The quartz baffle on the inclined baffle 4 rolls toward the lower end along the supporting surface of the inclined baffle 4 and falls to the higher end of the second screening plate 3. Then, the quartz sand particles with slightly smaller particles roll toward the lower end along the upper surface of the second screening plate 3 for secondary screening. The quartz sand particles with slightly smaller particles roll out from the second discharge port 13. The smallest quartz sand particles pass through the second screening plate 3 and roll out from the third discharge port 14, thereby completing the three-level screening of the quartz sand particles. The presence of the inclined baffle 4 can prevent the quartz sand particles screened from the first screening plate 2 from directly hitting the second screening plate 3 and directly popping out of the second discharge port 13, thereby improving the screening quality of the quartz sand. Secondly, the presence of the inclined baffle 4 can guide the falling quartz sand particles to roll toward the higher end of the second screening plate 3, thereby increasing the horizontal moving distance of the quartz sand particles on the second screening plate 3 and improving the screening quality of small quartz sand particles.

[0026] In the above technical scheme, the presence of the inclined baffle plate 4 can prevent the quartz sand particles screened off the first screening plate 2 from directly colliding with the second screening plate 3 and the second discharge port 13 from directly popping out, thereby improving the screening quality of the quartz sand. Secondly, the presence of the inclined baffle plate 4 can guide the fallen quartz sand particles to roll toward the high end of the second screening plate 3, thereby increasing the horizontal moving distance of the quartz sand particles on the second screening plate 3 and improving the screening quality of small-particle quartz sand.

[0027] As an embodiment further provided by the present invention, the high end of the inclined baffle 4 is rotatably arranged in the box body 1, and a flip seat 81 is also rotatably arranged in the box body 1, and a telescopic seat 82 is slidably arranged on the flip seat 81, and the end of the telescopic seat 82 is movably arranged on the inclined baffle 4, and the telescopic seat 82 is driven to slide back and forth on the flip seat 81 so that the inclined baffle 4 flips and shakes back and forth.

[0028] Specifically, Figure 2As shown, the right end of the flip seat 81 is rotatably set on the box body 1, and the telescopic seat 82 is slidably set in the flip seat 81, and the telescopic seat 82 is driven to slide by the driving cylinder 83 in the flip seat 81, and the left end of the telescopic seat 82 is movably set in the movable groove 41 opened on the inclined baffle 4, and the telescopic seat 82 can be reciprocated on the flip seat 81 by the driving cylinder 83, so that the inclined baffle 4 is flipped back and forth for shaking, and the inclined baffle 4 is flipped and shaken to make the quartz sand particles supported on the supporting surface of the inclined baffle 4 fall to the high end of the second screening plate 3 faster, thereby improving the screening efficiency of the quartz sand particles.

[0029] As a further embodiment of the present invention, an air charging duct 5 inclined toward the lower end of the inclined baffle 4 is provided on the box body 1, and an air outlet duct 6 opposite to the air charging duct 5 and located at the higher end of the inclined baffle 4 is also provided in the box body 1.

[0030] Specifically, Figure 1 As shown, the filling air duct 5 is arranged on the box body 1 to be inclined toward the lower end of the inclined baffle 4, and the filling air duct 5 is facing the box body 1, and the air outlet 6 is located at the high end of the inclined baffle 4. When the filling air duct 5 fills gas into the box body 1, the filling air duct 5 can blow out the dust brought by the falling quartz sand particles to the air outlet 6, thereby reducing the dust entrained by the quartz sand particles after screening and improving the product quality of the quartz sand. The filling air duct 5 can also blow air to slow down the quartz sand particles rolling and falling on the inclined baffle 4, reducing the flying of the quartz sand particles when falling. Secondly, when the inclined baffle 4 is driven to flip and shake, it can further separate the large and small particles of the quartz sand particles, and separate the dust from the quartz sand particles, thereby further improving the screening efficiency of the quartz sand particles and the removal effect of the entrained dust.

[0031] Furthermore, a shielding net 51 may be provided in the air filling duct 5 to prevent quartz sand particles from falling into the air filling duct 5 .

[0032] As an embodiment further provided by the present invention, a linear array of raised portions 42 with arc-shaped cross sections are arranged on the supporting surface of the inclined baffle 4 .

[0033] Specifically, a linear array of raised portions 42 with arc-shaped cross sections are provided on the supporting surface of the inclined baffle 4 to further enhance the supporting and decelerating effect of the inclined baffle 4 on the quartz sand particles, and further alleviate the problem of the quartz sand particles flying when falling.

When the inclined baffle plate 4 is driven to flip and shake, the first end of the ventilation slot 43 can intermittently face the filling air duct 5. At this time, the gas flows along the ventilation slot 43 to the air outlet 431, and then the gas blows the dust sticking to the supporting surface of the inclined baffle plate 4 to fly, thereby further facilitating the removal of the dust.

[0036] As an embodiment further provided by the present invention, a flexible shielding member 71 for shielding the rotating part of the inclined baffle 4 is arranged in the box body 1.

[0037] Specifically, a flexible shielding member 71 is provided in the box body 1 to prevent quartz sand particles from rolling into the rotating part of the inclined baffle 4 and causing the inclined baffle 4 to be stuck in rotation, thereby improving the working stability of the inclined baffle 4.
