Description

Technical Field

[0001] This invention relates to the field of quartz sand processing, specifically to a dust suppression device for quartz sand production. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and screening quartz stone. Quartz stone is a non-metallic mineral, whose main mineral component is silicon dioxide (SiO2). Quartz sand can be classified according to quality into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand, and silica powder, etc. The production process of quartz sand generates a significant amount of dust, requiring dust suppression devices to absorb and treat the dust, thus ensuring a cleaner production environment.

[0003] When the dust suppression device for quartz sand production is in operation, it draws air from the dusty environment and draws the dust-laden air into the bag filter to adsorb the dust. The filtered air is then discharged.

[0004] However, when dust suppression devices used in current quartz sand production are in operation, excessive dust can easily cause the dust collection bags to become clogged, resulting in poor airflow and reduced work efficiency. Summary of the Invention

[0005] To solve the above-mentioned technical problems, a dust suppression device for quartz sand production is provided. This technical solution solves the problem mentioned in the background technology that excessive dust can easily lead to clogging of the dust collection bag, resulting in poor airflow and reduced work efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A dust suppression device for quartz sand production includes an electromagnetic adsorption chamber, a fan chamber located above the electromagnetic adsorption chamber, an air inlet chamber above the fan chamber, a cover plate on the top of the air inlet chamber, a base fixed at the four corners of the bottom of the cover plate, a return spring installed inside the base, a sliding column slidably connected to the base at the end of the return spring, a base attached to the inner wall of the air inlet chamber, a slot provided inside the base, a dust collection bag inside the slot, a retaining plate inside the slot, a second bolt threaded to the top of the retaining plate, the second bolt threaded to the base, an iron plate at the bottom of the dust collection bag, and a dual-axis electric push rod installed in the middle of the fan chamber, one output end of the dual-axis electric push rod connected to a magnet that cooperates with the iron plate.

[0008] Preferably, rotating rods are fixed on both sides of the other output end of the dual-axis electric push rod, and electromagnetic plates are fixedly installed on both sides of the top of the electromagnetic adsorption chamber. A scraper is slidably connected to the outside of the electromagnetic plate, and the scraper is fixedly connected to the end of the rotating rod.

[0009] Preferably, a storage compartment is provided at the bottom of the outer side of the electromagnetic plate, and a fastening bolt is threadedly connected to the bottom of the storage compartment. The fastening bolt is threadedly connected to the electromagnetic plate.

[0010] Preferably, both ends of the scraper are provided with cavities, and a pusher plate is fixed inside the cavity.

[0011] Preferably, the cross-section of the push plate is an obtuse triangle, the height of the push plate is two centimeters, and the width of the cavity is three centimeters.

[0012] Preferably, there are two electromagnetic plates, one of which is connected to the positive terminal of the power supply, and the other is connected to the negative terminal of the power supply.

[0013] Preferably, the electromagnetic adsorption chamber has air outlets at both ends, and a filter screen is installed inside the air outlet. The bottom of the electromagnetic adsorption chamber is rotatably connected to a base plate, and a latch is installed at the connection between the base plate and the electromagnetic adsorption chamber. Fans are installed at both ends inside the fan chamber.

[0014] Preferably, air inlets are provided on both sides of the top of the cover plate, and an air inlet pipe is connected to the top of the air inlet via a flange. First bolts are threadedly connected to the four corners of the top of the cover plate, and the first bolts are threadedly connected to the air inlet chamber.

[0015] Preferably, a silicone pad is provided on the outer side of the base, the base is tightly fitted to the inner wall of the air intake chamber, the dust bag extends through to the bottom of the base, and the top of the dust bag is located between the card plate and the card slot.

[0016] Preferably, there are four sliding posts, and the bottoms of the four sliding posts are in contact with the top of the second bolt.

[0017] Compared with the prior art, the present invention provides a dust suppression device for quartz sand production, which has the following beneficial effects: 1. Start by using the dual-axis electric push rod. One output end of the dual-axis electric push rod pushes the magnet to move up and down reciprocally. At this time, the magnet cooperates with the iron plate, and the magnet drives the dust bag to vibrate up and down, which can reduce the clogging of the dust bag. At the same time, the first bolt is tightened, so that the cover plate is disengaged from the air inlet chamber. At this time, the sliding column loses the downward pressure on the base. Then, the base is pulled to drive the dust bag away from the air inlet chamber for cleaning. When the dust bag is damaged, tighten the second bolt to remove the clamping plate from the slot. Then, the clamping plate loses the clamping force on the dust bag. Replace the damaged dust bag. After that, put the magnet into the dust bag and reset the base and cover plate. 2. The dual-axis electric push rod is activated, and the other output end of the dual-axis electric push rod moves up and down. At this time, the output end of the dual-axis electric push rod pulls the rotating rod to move up and down. When the scraper around the outside of the electromagnetic plate moves downward, the scraper scrapes the dust particles with charged adsorbed on the outside of the electromagnetic plate downward and into the collection compartment. When the scraper moves upward, under the action of the push plate, the dust adhering to the outside of the electromagnetic plate is pushed down through the cavity or directly detached from the electromagnetic plate and falls back onto the electromagnetic plate. When the scraper descends again, it pushes the dust into the collection compartment. Attached Figure Description

[0028] Please refer to Figures 1-6As shown, a dust suppression device for quartz sand production includes an electromagnetic adsorption chamber 1, a fan chamber 2 located above the electromagnetic adsorption chamber 1, an air inlet chamber 5 above the fan chamber 2, a cover plate 8 on the top of the air inlet chamber 5, a base 12 fixed at the four corners of the bottom of the cover plate 8, a return spring 13 installed inside the base 12, a sliding column 14 slidably connected to the base 12 fixed at the end of the return spring 13, a base 15 attached to the inner wall of the air inlet chamber 5, a slot 18 opened inside the base 15, a dust collection bag 10 installed inside the slot 18, a card plate 16 installed inside the slot 18, a second bolt 17 threadedly connected to the top of the card plate 16, the second bolt 17 threadedly connected to the base 15, an iron plate 11 installed at the bottom inside the dust collection bag 10, a dual-axis electric push rod 20 installed in the middle position inside the fan chamber 2, and a magnet 21 cooperating with the iron plate 11 connected to one output end of the dual-axis electric push rod 20.

[0029] In this embodiment, the dual-axis electric push rod 20 is activated. One output end of the dual-axis electric push rod 20 pushes the magnet 21 to move up and down reciprocally. At this time, the magnet 21 cooperates with the iron plate 11. The magnet 21 drives the dust bag 10 to vibrate up and down, which can reduce the blockage of the dust bag 10. At the same time, the first bolt 6 is tightened, so that the cover plate 8 is disengaged from the air inlet chamber 5. At this time, the sliding column 14 loses the downward pressure on the base 15. Then, the base 15 is pulled to drive the dust bag 10 away from the air inlet chamber 5 to clean the dust bag 10. When the dust bag 10 is damaged, the second bolt 17 is tightened to remove the clamping plate 16 from the clamping slot 18. Then, the clamping plate 16 loses the clamping force on the dust bag 10. The damaged dust bag 10 is replaced. After that, the magnet 21 is put into the dust bag 10 and the base 15 and the cover plate 8 are reset.

[0030] Example 2

[0031] Please refer to Figure 5 As shown, rotating rods 23 are fixed on both sides of the other output end of the dual-axis electric push rod 20. Electromagnetic plates 24 are fixedly installed on both sides of the top of the electromagnetic adsorption chamber 1. Scraper 22 is slidably connected to the outer side of the electromagnetic plate 24. The scraper 22 is fixedly connected to the end of the rotating rod 23.

[0032] In this embodiment, one output end of the dual-axis electric push rod 20 drives the rotating rod 23 to move up and down, and the rotating rod 23 drives the scraper 22 to move up and down, and the scraper 22 scrapes the surface of the electromagnetic plate 24.

[0033] Example 3

[0034] Please refer to Figure 6As shown, a storage compartment 25 is provided at the bottom of the outer side of the electromagnetic plate 24. The bottom of the storage compartment 25 is connected to a fastening bolt 26 by a thread. The fastening bolt 26 is connected to the electromagnetic plate 24 by a thread. Both ends of the scraper 22 are provided with cavities 27. A push plate 28 is fixed inside the cavity 27. The cross-section of the push plate 28 is an obtuse triangle, and the height of the push plate 28 is two centimeters. The width of the cavity 27 is three centimeters.

[0035] In this embodiment, when the scraper 22 surrounding the outside of the electromagnetic plate 24 moves downward, the scraper 22 scrapes the dust with charged particles adsorbed on the outside of the electromagnetic plate 24 downward and into the collection chamber 25. When the scraper 22 moves upward, under the action of the push plate 28, the dust attached to the outside of the electromagnetic plate 24 is pushed down through the cavity 27 or directly detached from the electromagnetic plate 24 and falls back onto the electromagnetic plate. When the scraper 22 descends again, it pushes the dust into the collection chamber 25.

[0036] Example 4

[0037] Please refer to Figure 1 and Figure 4 As shown, there are two electromagnetic plates 24. One electromagnetic plate 24 is connected to the positive terminal of the power supply, and the other electromagnetic plate 24 is connected to the negative terminal of the power supply. Air outlets 4 are opened at both ends of the electromagnetic adsorption chamber 1. A filter screen is installed inside the air outlet 4. The bottom of the electromagnetic adsorption chamber 1 is rotatably connected to the bottom plate 3. A latch is installed at the connection between the bottom plate 3 and the electromagnetic adsorption chamber 1. Fans 19 are installed at both ends inside the fan chamber 2. Air inlets 9 are opened on both sides of the top of the cover plate 8. An air inlet pipe 7 is connected to the top of the air inlet 9 through a flange.

[0038] In this embodiment, two electromagnetic plates 24 are connected to the positive and negative terminals of the power supply, forming a magnetic field between them. Dust with charged ions is adsorbed onto the electromagnetic plates 24. The air outlet 4 works with the filter screen to complete the air outlet. The fan 19 is started to form an air duct, drawing in the dusty air from the air inlet pipe 7 and letting it flow out from the air outlet 4. The latch is designed to fix the rotating base plate 3, making it easy to open or close the base plate 3 by rotation.

[0039] Example 5

[0040] Please refer to Figures 1-4 As shown, the four corners of the top of the cover plate 8 are connected by threads to the first bolt 6, which is connected to the air intake chamber 5 by threads. A silicone pad is provided on the outside of the base 15, and the base 15 is tightly fitted to the inner wall of the air intake chamber 5. The dust bag 10 extends to the bottom of the base 15, and the top of the dust bag 10 is located between the card plate 16 and the card slot 18. There are four sliding columns 14, and the bottom of the four sliding columns 14 is in contact with the top of the second bolt 17.

[0041] In this embodiment, the rotation of the first bolt 6 facilitates the disassembly of the cover plate 8 from the air intake chamber 5. Under the action of the return spring 13, the four sliding columns 14 are pushed downward by the return spring 13, thereby pressing the second bolt 17 and pressing down on the base 15. With the help of the silicone pad, a tight seal is formed between the base 15 and the inner wall of the air intake chamber 5. The clamping plate 16 and the clamping groove 18 cooperate with each other, thereby tightly clamping the dust bag 10 located between the clamping plate 16 and the clamping groove 18, realizing the installation of the dust bag 10.
