A high-efficiency quartz sand drying device

Abstract

This invention discloses a high-efficiency quartz sand drying device, including a protective shell, a quartz sand smoothing mechanism, a conveying mechanism, and a drying mechanism. When the driving mechanism drives the two first through-hole square columns in the quartz sand smoothing mechanism to rotate, and drives the two second round rods to rotate, the two L-shaped connecting ears, the two second through-hole square columns, and the two uprights will drive the four sleeves to slide back and forth on the outer walls of the four guide rods. During the back and forth sliding of the four sleeves on the outer walls of the four guide rods, the extension and retraction of the two first springs will drive the two second round rods to slide back and forth inside the two first through-hole square columns, and will also drive the two second through-hole square columns to slide up and down on the outer walls of the two uprights. This will drive the smoothing plate and the two round wheels to perform reciprocating rectangular motion, so that the smoothing plate can spread the quartz sand evenly on the rotating conveyor belt, which will facilitate the drying mechanism to fully dry the spread quartz sand and improve the drying efficiency.

Description

Technical Field

[0001] This invention belongs to the technical field of quartz sand processing, and specifically relates to a high-efficiency quartz sand drying device. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is milky white or colorless and translucent, with a Mohs hardness of 7. Quartz sand is an important industrial mineral raw material, a non-hazardous chemical, and is widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media, and other industries. Current drying equipment has low drying efficiency and poor dust control, so there is an urgent need to develop a dustproof quartz sand drying device that can improve the drying efficiency of quartz sand and reduce the dust generated during the drying process.

[0003] As disclosed in CN108826891B, a dust-proof drying device for quartz sand can improve drying efficiency and reduce dust generated during the drying process. This dust-proof drying device includes a heating rod, a first mounting plate, a first support rod, a first pulley, a gear, a slider, an annular slide rail, a guide roller, a second support rod, a wing bolt, a first nut, and a second nut. The first support rod is fixed to one side of the first mounting plate, and the second support rod is fixed to the other side of the first mounting plate. The annular slide rail is fixed to one end of the drying cylinder. This invention achieves the effect of improving the drying efficiency of quartz sand and removing dust generated during the drying process, ensuring that the dried quartz sand does not retain excessive dust.

[0004] However, the following problems exist: This application uses a horizontal drum drying process, which requires placing a large amount of quartz sand inside the drying drum. Although the quartz sand can be stirred by the stirring rods to speed up the drying efficiency, there are gaps between the stirring rods during the stirring process. This makes it easy for the quartz sand between the stirring rods to be covered by the stirred quartz sand, which can easily cause some quartz sand to not be dried properly, prolonging the drying time and reducing the drying efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency quartz sand drying device to solve the problem mentioned in the background art that the horizontal drum drying method can easily cause some quartz sand to fail to be dried properly, prolonging the drying time and reducing the efficiency of the drying process.

[0015] Compared with the prior art, the present invention provides a high-efficiency quartz sand drying device, which has the following beneficial effects:

[0016] 1. In this invention, when the driving mechanism drives the two first through-hole square columns in the quartz sand smoothing mechanism to rotate, and drives the two second round rods to rotate, the two L-shaped connecting ears, the two second through-hole square columns, and the two upright rods will drive the four sleeves to slide back and forth on the outer wall of the four guide rods. During the back and forth sliding of the four sleeves on the outer wall of the four guide rods, the extension and retraction of the two first springs will drive the two second round rods to slide back and forth inside the two first through-hole square columns, and will also drive the two second through-hole square columns to slide up and down on the outer wall of the two upright rods. This will drive the smoothing plate and the two round wheels to perform rectangular motion back and forth, so that the smoothing plate can spread the quartz sand flat on the rotating conveyor belt, which will facilitate the drying mechanism to fully dry the spread quartz sand and improve the drying efficiency.

[0017] 2. When the two round wheels contact the two crossbeams, the two round wheels will drive the two fourth round rods to slide to the right inside the two arc groove slide rails, and limit the angle of the rotating and swinging smoothing plate. It will also stretch the second spring, which helps the smoothing plate to spread the quartz sand evenly on the upper surface of the conveyor belt. When the two round wheels separate from the two crossbeams, the retraction of the second spring will pull the two fourth round rods to slide to the left inside the two arc groove slide rails, so that the smoothing plate returns to the initial state and causes the smoothing plate to vibrate, thus preventing the quartz sand from sticking to the surface of the smoothing plate.

[0018] 3. When the sixth round rod in the feeding mechanism is driven to rotate by the driving mechanism, the fixed disc, positioning disc and round shaft will be driven to rotate, so that the round shaft can enter the four U-shaped grooves one after another, and drive the groove wheel, the fifth round rod and the sealing round plate to rotate intermittently, thereby enabling the quartz sand in the feeding groove to achieve intermittent feeding, which helps the quartz sand smoothing mechanism to spread the quartz sand evenly.

[0019] 4. When the seventh round rod in the drive mechanism of the present invention rotates, it will drive the eccentric wheel to rotate, so that the sealing plate can rotate and swing up and down around the second connecting ear as the axis point, thereby enabling the dried quartz sand inside the discharge trough to complete the intermittent discharge work, and at the same time, it can also store the dried quartz sand conveyed by the conveyor belt.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] Please see Figure 1-17 This invention provides a technical solution: a high-efficiency quartz sand drying device, including a protective shell 3, a quartz sand smoothing mechanism, a conveying mechanism, and a drying mechanism. The lower right side of the protective shell 3 is provided with a discharge mechanism for discharging dried quartz sand. The lower inside of the protective shell 3 is provided with a conveying mechanism for conveying quartz sand to the discharge mechanism. The upper inside of the protective shell 3 near the conveying mechanism is provided with a quartz sand smoothing mechanism, which smooths the quartz sand onto the upper surface of the conveying mechanism. The top left side of the protective shell 3 is provided with a feed trough 2 for quartz sand input. The top center of the protective shell 3 is provided with a drying mechanism for drying. The protective shell 3 is provided with a driving mechanism, which drives the quartz sand smoothing mechanism, the feed mechanism, and the discharge mechanism to complete the quartz sand smoothing work, the intermittent input work, and the intermittent discharge work, respectively. A support frame 4 is welded to the lower outer wall of the protective shell 3. An intelligent controller 9 is installed on the front end of the protective shell 3.

[0040] The drive mechanism can rotate the third round rod 46, the sixth round rod 53, and the seventh round rod 60. When the third round rod 46 rotates, it will drive the first through-hole square post 41 to rotate. Through the two second round rods 42, the two L-shaped connecting ears 45, and the smoothing plate 37, it will drive the other first through-hole square post 41 and the first round rod 40 to rotate. When the two first through-hole square posts 41 rotate, the extension and retraction of the two first springs 44 will drive the two second round rods 42 to slide back and forth inside the two first through-hole square posts 41. Through the two L-shaped connecting ears 45, the two second through-hole square posts 43, and the two uprights 39, it will drive the four sleeves 38 to slide back and forth on the outer wall of the four guide rods 36, and it will also drive the two second through-hole square posts 43 to slide back and forth on the outer wall of the two uprights 39, thereby driving the smoothing plate 60 to rotate. The flat plate 37 and the two round wheels 21 reciprocate in a rectangular motion. When the two round wheels 21 contact the two crossbeams 26, they will drive the flat plate 37 to rotate and swing, so that the flat plate 37 can spread the quartz sand evenly on the upper surface of the conveyor belt 20, which will facilitate the drying mechanism to dry the spread quartz sand. This causes the two fourth round rods 47 to slide to the right inside the two arc groove slide rails 50, which limits the angle of the rotating and swinging flat plate 37 and also stretches the second spring 49. When the two round wheels 21 separate from the two crossbeams 26, the retraction of the second spring 49 will pull the two fourth round rods 47 to slide to the left inside the two arc groove slide rails 50, so that the flat plate 37 returns to its initial state and causes the flat plate 37 to vibrate, thus preventing the quartz sand from sticking to the surface of the flat plate 37.

[0041] When the sixth round rod 53 rotates, it will drive the fixed disc 54, the positioning disc 55 and the round shaft 57 to rotate, so that the round shaft 57 can enter the four U-shaped grooves 56 one after another, and drive the groove wheel 52, the fifth round rod 51 and the sealing round plate 58 to rotate intermittently, thereby enabling the quartz sand in the feed trough 2 to achieve intermittent feeding, which helps the quartz sand smoothing mechanism to spread the quartz sand evenly.

[0042] When the seventh round rod 60 rotates, it will drive the eccentric wheel 5 to rotate, so that the sealing plate 6 can rotate and swing up and down with the second connecting ear 62 as the axis, thereby enabling the dried quartz sand inside the discharge trough 7 to complete the intermittent discharge work.

[0043] like Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the quartz sand smoothing mechanism includes a smoothing plate 37, which also includes a connecting long shaft integrally formed at both ends. Round wheels 21 are sleeved on the outer walls of the connecting long shafts on both sides of the smoothing plate 37. A fourth round rod 47 is provided on the two round wheels 21 away from the outer wall of the smoothing plate 37.

The fourth round rod 47 slides within the arc-groove slide rail 50, allowing the smoothing plate 37 to perform a small-amplitude swing operation, facilitating the smoothing plate 37 to tilt and smooth the upper surface of the quartz sand conveyor belt 20. The outer wall of the two second through-hole square pillars 43 is provided with a limiting plate 48 on the left side near the arc-groove slide rail 50. The two limiting plates 48 and the two fourth round rods 47...

The two second through-hole square pillars 43 are slidably connected to upright rods 39, with both ends of the upright rods 39 extending through and beyond the ends of the second through-hole square pillars 43. Sleeves 38 are welded to the upper ends of the two upright rods 39. Guide rods 36 are slidably connected inside the four sleeves 38, with both ends of the guide rods 36 extending through and beyond the ends of the sleeves 38. Fixing seats 35 are welded to both ends of the four guide rods 36. Welded to the inner wall of the protective housing 3, two second through-hole square pillars 43 are rotatably connected to the middle of their end faces away from the round wheel 21 by L-shaped connecting ears 45. The bottom of the two L-shaped connecting ears 45 is provided with a second round rod 42. A first through-hole square pillar 41 is slidably fitted onto the lower outer wall of the two second round rods 42. A first round rod 40 and a third round rod 46 are respectively welded to the end faces of the two first through-hole square pillars 41 near the protective housing 3, and the two first through-hole square pillars 41 are rotatably connected to the protective housing 3 through the first round rod 40 and the third round rod 46 respectively. Simultaneously, the second... Three round rods 46 extend through the protective outer shell 3. The upper outer walls of the two second round rods 42 are fitted with first springs 44, and the two ends of the first springs 44 contact the first through-hole square post 41 and the L-shaped connecting ear 45 respectively. The extension and retraction of the first springs 44 facilitates the reciprocating sliding of the second round rods 42 inside the first through-hole square post 41. Through the quartz sand smoothing mechanism, the reciprocating smoothing work can be realized, so that the quartz sand can be spread evenly on the upper surface of the conveyor belt 20, which facilitates the drying mechanism to dry the spread quartz sand and improves the drying efficiency.

[0044] like Figure 3 , Figure 4 , Figure 12 and Figure 13As shown, the feeding mechanism includes a feeding trough 2 and a conveying pipe 18. The feeding trough 2 is welded to the left side of the upper end face of the protective shell 3.

A fixed disc 54 is sleeved on the outer wall of the sixth round rod 53 near the rear side of the grooved wheel 52, and the front end face of the fixed disc 54 contacts the rear end face of the grooved wheel 52. A positioning disc 55 is welded to the front end face of the fixed disc 54 near the outer wall of the sixth round rod 53, and the edge of the positioning disc 55 abuts against the arc surface of the grooved wheel 52. A round shaft 57 is welded to the lower end face of the fixed disc 54, and the diameter of the round shaft 57 is the same as the width of the U-shaped groove 56. When the fixed disc 54 rotates, the round shaft 57 can enter and exit the four U-shaped grooves 56 successively, and intermittently actuate the grooved wheel 52, the fifth round rod 51, and the sealing disc 58 to rotate. Figure 3 and Figure 4 As shown, the conveying pipe 18 is welded to the top left side of the protective shell 3, and the conveying pipe 18 is located directly below the feed trough 2. Through the feeding mechanism, intermittent conveying work can be realized, which is beneficial for the quartz sand smoothing mechanism to spread the quartz sand evenly on the upper surface of the conveyor belt 20.

A second connecting ear 62 is welded to the lower side of the left end face of the discharge trough 7.

A seventh round rod 60 is rotatably connected to the lower side of the two double-hole connecting blocks 27, and the front end of the seventh round rod 60 extends through the double-hole connecting blocks 27 on the front side. An eccentric wheel 5 is sleeved on the rear outer wall of the seventh round rod 60, and the wheel edge of the eccentric wheel 5 abuts against the lower surface of the sealing plates 6. The rotation of the eccentric wheel 5 facilitates the up-and-down swing of the sealing plates 6. Through the discharge mechanism, intermittent discharge can be achieved.

Through the drive mechanism, the quartz sand smoothing mechanism, the feeding mechanism, and the discharging mechanism can be driven more effectively.

[0047] like Figure 16 As shown, the conveying mechanism includes two crossbeams 26, two first support seats 11, a first drive motor 8, a conveyor belt 20, and a partition plate 63. The two crossbeams 26 are welded to the inner walls of the front and rear sides of the protective shell 3. A first drive roller 14 and several second drive rollers 19 are rotatably connected between the two crossbeams 26 in a left-to-right sequence. Both ends of the several second drive rollers 19 extend through the two crossbeams 26. A conveyor belt 20 is provided between the two crossbeams 26, and the several second drive rollers 19 and the first drive rollers 14 are all located inside the conveyor belt 20. The several second drive rollers 19 and the first drive rollers 14 drive the conveyor belt 20 to rotate. Annular limit blocks 65 are provided on the outer walls of both sides of the conveyor belt 20. Bearing seats 12 are rotatably connected to the outer walls of both sides of the first drive rollers 14, and the bearing seats 12 are located on the outside of the protective shell 3. The two first support seats 11 are welded to the left sides of the front and rear ends of the protective shell 3. The internal thread of the first support seat 11 is connected to a lead screw 15, and both ends of the lead screw 15 extend through the two ends of the first support seat 11. At the same time, the right end of the lead screw 15 is rotatably connected to the left end of the bearing seat 12. The left ends of the two lead screws 15 are welded with handles 16, and the handles 16 are located on the left side of the first support seat 11. The left side of the two crossbeams 26 is provided with a second limiting groove 64, and both ends of the first transmission roller 14 extend through the second limiting groove 64 and slide inside the second limiting groove 64. The first drive motor 8 is installed on the front end face of the protective shell 3, and the first drive motor 8 drives the second transmission roller 19 on the right side to rotate. The two ends of the partition 63 are welded to the inner walls of both sides of the protective shell 3. The partition 63 is located on the left side of the upper surface of the conveyor belt 20, and the lower surface of the partition 63 is in contact with the upper surface of the conveyor belt 20. Through the conveying mechanism, the quartz sand can be conveyed better, and at the same time, it is also convenient for the quartz sand smoothing mechanism to spread the quartz sand.

[0048] like Figure 3 , Figure 4 and Figure 17 As shown, the drying mechanism includes a heater 1, an air outlet slot 22, a fan 10, a base 69, and a gas adapter 70. The gas adapter 70 is welded to the upper inner wall of the protective shell 3, and the upper end of the gas adapter 70 extends through the upper surface of the protective shell 3. The lower end of the gas adapter 70 is provided with several air outlet slots 22, which are located inside the protective shell 3. The base 69 is installed on the upper surface of the protective shell 3. The heater 1 is provided on the left side of the upper surface of the base 69. An air pipe 66 connects the heater 1 and the gas adapter 70. The motor support 68 is provided on the right side of the upper surface of the base 69. A third drive motor 67 is installed on the upper surface of the motor support 68. The fan 10 is sleeved on the outer wall of the motor shaft of the third drive motor 67, and the fan 10 is installed on the right end face of the heater 1. Through the drying mechanism, the drying work can be carried out better.

[0049] like Figure 1 and Figure 2 As shown, the upper left side of the protective shell 3 is provided with a feed inlet 17, which is connected to the feed trough 2 and the conveying pipe 18 respectively. The lower right side of the protective shell 3 is provided with a discharge outlet 23, which is connected to the discharge trough 7. The lower sides of the front and rear ends of the protective shell 3 are provided with a first limiting groove 13 that matches the first transmission roller 14, and the first limiting groove 13 is connected to the second limiting groove 64. The protective shell 3 can better perform the protection work, and at the same time, it is also convenient for the installation of various components.

[0050] In order to achieve intelligent control, the intelligent controller 9 is electrically connected to the heater 1, the first drive motor 8, the second drive motor 24 and the third drive motor 67 via wires. Intelligent control can be achieved through the intelligent controller 9.

[0051] The second drive motor 24 has a higher speed than the first drive motor 8, which allows the quartz sand smoothing mechanism to better spread the quartz sand on the upper surface of the conveyor belt 20. At the same time, it also makes it easier for the working efficiency of the feeding mechanism and the discharging mechanism to be slightly higher than that of the conveying mechanism.

[0052] The working principle and usage process of this invention: When in use, the staff first connects the intelligent controller 9 to the external power supply and operates the intelligent controller 9 to complete the parameter setting. Then, the staff pours the quartz sand to be dried into the feed trough 2 and stores the quartz sand to be dried in the feed trough 2 through the horizontal sealing circular plate 58. Subsequently, the staff places the collection trough under the discharge mechanism at an angle.

[0053] When in use, the staff can operate the intelligent controller 9 to control the heater 1, the first drive motor 8, the second drive motor 24, and the third drive motor 67 to work.

[0054] When heater 1 and third drive motor 67 are working, hot air is generated and blown to conveyor belt 20 through air pipe 66, gas adapter 70 and several air outlet slots 22.

[0055] When the first drive motor 8 is working, it will drive the second transmission roller 19 on the right to rotate, thereby driving the conveyor belt 20 and the two annular limit blocks 65 to rotate.

[0056] When the second drive motor 24 is working, it will drive the second double-groove transmission wheel 34 to rotate. Since the second double-groove transmission wheel 34 and the first single-groove transmission wheel 28 are connected by a first transmission belt 29, the second double-groove transmission wheel 34 and the first double-groove transmission wheel 31 are connected by a second transmission belt 30, and the first double-groove transmission wheel 31 and the second single-groove transmission wheel 33 are connected by a third transmission belt 32, when the second double-groove transmission wheel 34 rotates, it will drive the first single-groove transmission wheel 28, the first double-groove transmission wheel 31 and the second single-groove transmission wheel 33 to rotate, thereby driving the third round rod 46, the sixth round rod 53 and the seventh round rod 60 to rotate.

[0057] When the sixth round rod 53 rotates, it will drive the fixed disc 54, the positioning disc 55 and the round shaft 57 to rotate, so that the round shaft 57 can enter the four U-shaped grooves 56 one after another, and drive the groove wheel 52, the fifth round rod 51 and the sealing round plate 58 to rotate intermittently, so that the quartz sand in the feed trough 2 can achieve intermittent feeding. Through the feed port 17 and the feed pipe 18, the quartz sand to be dried will fall on the upper surface of the conveyor belt 20 and be located on the right side of the partition 63. At this time, the rotating conveyor belt 20 will transport the quartz sand to be dried.

[0058] When the third round rod 46 rotates, it will drive the first through hole square column 41 on the front side to rotate. At this time, through the two second round rods 42, the two L-shaped connecting ears 45, and the smoothing plate 37, the first through hole square column 41 and the first round rod 40 on the rear side will rotate. When the two first through hole square columns 41 rotate, they will drive the two second round rods 42 to rotate. Through the two L-shaped connecting ears 45, the two second through hole square columns 43, and the two uprights 39, the four sleeves 38 will slide back and forth on the outer wall of the four guide rods 36. During the process of the four sleeves 38 sliding back and forth on the outer wall of the four guide rods 36, through the extension and retraction of the two first springs 44, the two second round rods 42 will slide back and forth inside the two first through hole square columns 41, and the two second through hole square columns 43 will slide up and down on the outer wall of the two uprights 39, thereby driving the smoothing plate 37 and the two round wheels 21 to perform rectangular motion back and forth.

[0059] When the smoothing plate 37 and the two wheels 21 move to the lower side and the two wheels 21 contact the two crossbeams 26, the smoothing plate 37 will rotate and swing, which facilitates the smoothing plate 37 to spread the quartz sand evenly on the upper surface of the conveyor belt 20, and also facilitates the drying mechanism to dry the spread quartz sand. At the same time, the two fourth rods 47 slide to the right inside the two arc groove slide rails 50 and limit the angle of the rotating and swinging smoothing plate 37. They also stretch the second spring 49, which helps the smoothing plate 37 to spread the quartz sand evenly on the upper surface of the conveyor belt 20. When the two wheels 21 separate from the two crossbeams 26, the retraction of the second spring 49 pulls the two fourth rods 47 to slide to the left inside the two arc groove slide rails 50, so that the smoothing plate 37 returns to the initial state and causes the smoothing plate 37 to vibrate, thus preventing the quartz sand from sticking to the surface of the smoothing plate 37.

[0060] When the seventh rod 60 rotates, it will drive the eccentric wheel 5 to rotate, so that the sealing plate 6 can rotate and swing up and down around the second connecting ear 62 as the axis. This allows the dried quartz sand inside the discharge trough 7 to complete the intermittent discharge work. At the same time, the dried quartz sand conveyed by the conveyor belt 20 can also be stored through the discharge trough 7 and the horizontal sealing plate 6.
