[0002] Quartz sand is quartz particles formed by crushing and processing quartz stone. Its main component is silicon dioxide, and it comes in various colors. Quartz sand screening is a key step in the quartz sand production process. Because different industrial applications have specific requirements for the size of quartz sand particles, screening can classify quartz sand according to particle size to ensure uniform particle size.

[0003] During the screening of quartz sand, workers will pour the quartz sand into the screening screen through the feeding device. The screening device will vibrate to allow the quartz sand that meets the size requirements to fall from the screen. Then, the collection device will collect the quartz sand that meets the requirements.

[0004] The existing technology has the following drawbacks: some existing equipment relies on gravity for feeding, and since the size of the feed inlet is fixed, excessive feed volume can easily cause material accumulation, reducing the screening efficiency of quartz sand. In addition, the vibration device generates a lot of noise during quartz sand screening, which affects the health of the workers. Therefore, a high-strength quartz sand screening device for fracturing is proposed to solve the above problems. Utility Model Content

The output end of the motor 7 is fixedly connected to the turntable 5. The outer wall of the bracket 2 is hinged to the rotating rod 6. The bottom end of the filter box 1 is fixedly connected to the base 15. The outer wall of the turntable 5 is provided with an adjustment mechanism. The outer wall of the filter box 1 is provided with a noise reduction component. The adjustment mechanism includes a moving column 8. The inner wall of the moving column 8 is slidably connected to a slider 10. The inner wall of the moving column 8 has a slot corresponding to the slider 10, allowing the slider 10 to move left and right. The inner wall of the left end of the slider 10 is elastically connected to a locking block 9 through a movable spring 11. The moving column 8 is slidably connected to the outer wall of the turntable 5. The outer wall of the turntable 5 has a slot corresponding to the moving column 8, allowing the moving column 8 to move vertically.

[0037] Reference Figure 1 , Figure 7 and Figure 8 The noise reduction component includes a sound insulation panel 12. Both the sound insulation panel 12 and the movable plate 13 are provided with sound-absorbing sponges, which can reduce noise. The movable plate 13 is inserted into the right side wall of the sound insulation panel 12, and a protrusion is provided on the left side wall of the movable plate 13. The sound insulation panel 12 has two sets of slots corresponding to the protrusions, allowing the sound insulation panel 12 and the movable plate 13 to be spliced. The sound insulation panel 12 and the movable plate 13 are connected by bolts 14. The slots of the sound insulation panel 12 and the movable plate 13 are provided with threads that match the bolts 14. By turning the bolts 14, the sound insulation panel 12 and the movable plate 13 can be spliced ​​and disassembled. The sound insulation panel 12 contacts the outer wall of the filter box 1, and the movable plate 13 contacts the outer wall of the filter box 1. Both the sound insulation panel 12 and the movable plate 13 are in contact with the top of the base 15, and the base 15 provides support for the sound insulation panel 12 and the movable plate 13.

[0038] Reference Figures 4-6The inner wall of the left end of slider 10 is fixedly connected to one end of movable spring 11, and the other end of movable spring 11 is fixedly connected to the left side wall of locking block 9. When slider 10 and locking block 9 approach each other, movable spring 11 is compressed. During reset, the elastic force of movable spring 11 is used to reset slider 10 and locking block 9. Baffle 4 is fixedly connected to the outer wall of rotating rod 6, and locking block 9 is slidably connected to the inner wall of slider 10. The inner wall of slider 10 has a slot corresponding to locking block 9, allowing locking block 9 to... The moving column 8 is slidably connected to the inner wall of the rotating rod 6 by moving left and right. The rotating rod 6 has a slot corresponding to the moving column 8. When the moving column 8 presses against the slot, the rotating rod 6 will deflect around the hinge point. The feed box 3 is fixedly connected to the outer wall of the bracket 2. The slider 10 is inserted into the inner wall of the turntable 5. The locking block 9 is inserted into the inner wall of the turntable 5. The inner wall of the turntable 5 has a slot corresponding to the slider 10 and the locking block 9. The slider 10 and the locking block 9 are initially inserted into the slot.

[0039] Working principle: When it is necessary to reduce the amount of quartz sand added, press the slider 10 and the locking block 9 with your hand. When the slider 10 and the locking block 9 move closer together, they will compress the movable spring 11. When the slider 10 and the locking block 9 separate from the slot on the turntable 5, move the slider 10 and the locking block 9 upwards with your hand. The slider 10 and the locking block 9 will move the moving column 8 upwards with them. When the moving column 8 moves to a position close to the center, release the slider 10 and the locking block 9 with your hand. The elastic force of the movable spring 11 will cause the slider 10 and the locking block 9 to separate from each other and insert into the slot of the turntable 5, thus completing the limit of the moving column 8. At this time, turn on the motor 7, and the motor 7 will drive... As the turntable 5 and the moving column 8 rotate, the moving column 8 will press against the slot of the rotating rod 6, causing the rotating rod 6 to swing left and right with the baffle 4. When the baffle 4 swings left and right, it will not block the slot on the feed box 3, and the material in the feed box 3 will fall into the filter box 1. When the feed rate needs to be increased, the moving column 8 is moved downward by hand. When the moving column 8 moves to the desired position, the slider 10 and the locking block 9 are inserted into the slot to limit the moving column 8. At this time, the moving column 8 is farther away from the center, the swing amplitude of the rotating rod 6 is larger, and the feed rate is greater. If the feed rate needs to be adjusted again, just repeat the above operation steps.

[0040] When screening quartz sand, the vibration device will generate a lot of noise. The sound-absorbing sponge on the sound insulation plate 12 and the movable plate 13 will reduce the noise and reduce the impact of noise on the human body.

[0041] When the sound insulation cotton needs to be replaced, rotate bolt 14 by hand. When bolt 14 separates from the groove on the sound insulation plate 12, move the sound insulation plate 12 and the movable plate 13 to both sides by hand. After the sound insulation plate 12 and the movable plate 13 separate, the staff replaces the sound insulation foam. After the sound insulation foam is replaced, align the movable plate 13 by hand and insert it into the groove on the sound insulation plate 12. At this time, bolt 14 is aligned with the groove on the sound insulation plate 12. Rotate bolt 14 to limit the sound insulation plate 12 and the movable plate 13. If the sound insulation foam needs to be replaced again, simply repeat the above steps.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
