Description

Technical Field

[0001] This utility model relates to the technical field of quartz sand filter media, and in particular to a rolling screening device for quartz sand filter media. Background Technology

[0002] Quartz sand is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO2. Quartz sand is an important industrial mineral raw material, a non-hazardous chemical, and is widely used in industries such as glass and casting. Quartz sand is made from natural quartz ore through crushing, screening, and washing processes. It has the characteristics of high mechanical strength, strong interception capacity, and good acid resistance.

[0003] A quartz sand filter media grading and screening device with authorization announcement number CN222267884U proposes that the presence of inclined baffles can prevent quartz sand particles screened off the first screening plate from directly impacting the second screening plate and being ejected directly from the second discharge port, thereby improving the screening quality of quartz sand. Secondly, the presence of inclined baffles can guide the falling quartz sand particles to roll towards the higher end of the second screening plate, thereby increasing the horizontal movement distance of the quartz sand particles on the second screening plate and improving the screening quality of small quartz sand particles.

[0004] However, in practice, we have found that when a large amount of quartz sand passes through the first screening plate, because the angle of the first screening plate is fixed, when the angle is large, after a large amount of quartz sand enters, the fine quartz sand is discharged along with the large particles of quartz sand without being screened, and is not thoroughly screened. When the angle is small, after a large amount of quartz sand enters, it is easy for the quartz sand to accumulate on the first screening plate, resulting in a reduction in screening efficiency. In view of this, this utility model provides a rolling screening device for quartz sand filter media. Utility Model Content

[0005] The purpose of this application is to provide a rolling screening device for quartz sand filter media to solve the problems mentioned in the background art.

[0010] Preferably, the U-shaped screening disc has a plurality of screening holes evenly distributed, and an arc-shaped guide plate is fixedly installed on the top of the U-shaped screening disc between the screening holes.

[0011] Preferably, a vibration motor is fixedly installed on the top of both the U-shaped screening disc and the filter screen plate, and the filter screen plate has an inclined structure.

[0012] Preferably, a limiting rod is fixedly installed inside the adjusting frame by bolts, and both ends of the adjusting block move through the limiting rod.

[0013] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, the adjusting block on the screw is driven by a servo motor to change from rotational motion to linear motion under the action of the limiting rod. During the movement, the adjusting block adjusts the angle of the U-shaped screening disc on the rotating shaft through the hinge, hinge rod and movable groove, so that the tilt angle of the U-shaped screening disc is adjusted, so that the feeding speed of the U-shaped screening disc is different, thereby achieving different degrees of screening effect. 2. In this utility model, when there is a lot of quartz sand in the feed hopper, the tilt angle of the U-shaped screening disc is increased so that the quartz sand will not accumulate on the U-shaped screening disc, thereby improving the screening efficiency of the quartz sand. When there is less quartz sand in the feed hopper, the tilt angle of the U-shaped screening disc is reduced so that the residence time of the quartz sand on the U-shaped screening disc is increased, thereby improving the screening effect of the quartz sand.

The adjustment assembly includes a screw 31 that moves inside the adjustment frame 30. The bottom of the adjustment frame 30 is movably connected to a U-shaped screening disk 20 via a rotating shaft 21. An adjustment block 32 is threaded through the screw 31. A hinge rod 34 is movably connected between the adjustment block 32 and the U-shaped screening disk 20 via a hinge 33.

[0019] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A conical discharge hopper 12 is fixedly installed at the center of the bottom of the screening box 10. The screened quartz sand filter material is directly discharged through the discharge hopper 12. Support feet 13 are fixedly installed around the bottom of the screening box 10. A U-shaped screening disc 20 is evenly provided with several screening holes 22. The quartz sand filter material is filtered and screened through the screening holes 22, and the smaller diameter quartz sand falls into the bottom of the screening box 10. An arc is fixedly installed on the top of the U-shaped screening disc 20 between the screening holes 22. The curved guide plate 23 increases the residence time of quartz sand on the U-shaped screening disc 20. The top of both the U-shaped screening disc 20 and the filter screen plate 17 are fixedly installed with a vibration motor 40 to improve the screening effect. The filter screen plate 17 has an inclined structure. The inside of the adjusting frame 30 is fixedly installed with a limit rod 37 by bolts. The two ends of the adjusting block 32 move through the limit rod 37, so that the adjusting block 32 changes from rotational motion to linear reciprocating motion in the limit rod 37.

[0020] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A servo motor 35 is fixedly installed on the inner top of the adjusting frame 30, and the top end of the screw 31 is fixedly installed on the output end of the servo motor 35. The servo motor 35 drives the screw 31 to rotate. The adjusting frame 30 has a movable slot 36, and the hinge rod 34 moves through the movable slot 36.

[0022] The working principle of this utility model is as follows: Quartz sand is injected into the screening box 10 through the feed hopper 11. The quartz sand is screened and filtered on the U-shaped screening disc 20 through the screening holes 22 and the arc-shaped guide plate 23. The quartz sand moves downward on the U-shaped screening disc 20 due to gravity. During the falling process, it is buffered and screened through the screening holes 22 and the arc-shaped guide plate 23. The quartz sand enters the filter screen plate 17 through the screening holes 22 of the U-shaped screening disc 20, and is then filtered and screened through the filter screen plate 17. The filtered quartz sand is discharged through the second discharge chute 15 and the discharge pipe 16. The servo motor 35 drives the adjusting block 32 on the screw 31 to change from rotational motion to linear motion under the action of the limit rod 37. During the movement, the adjusting block 32 adjusts the angle of the U-shaped screening disk 20 on the rotating shaft 21 through the hinge 33, hinge rod 34 and movable groove 36, so that the tilt angle of the U-shaped screening disk 20 is adjusted, so that the feeding speed of the U-shaped screening disk 20 is different, thereby achieving different degrees of screening effect.
