Description

Technical Field

[0001] The present invention relates to the technical field of conveyor dust spill prevention equipment, and specifically relates to a dust removal device for a transfer station feed chute. Background Art

[0002] Currently, the common dust removal methods for the closed feed chute of the steel plant belt conveyor are air flow circulation dust removal and damping curtain dust removal. The closed feed chute generally fits with the belt surface through the anti-spill skirt plates on both sides to prevent the material dust on the belt from overflowing through the gap between the feed chute and the belt. In order to reduce the resistance during belt transmission, multiple sets of rollers are generally used to support the bottom surface of the belt.

[0003] There is a certain gap between the existing rollers on the belt conveyor. The belt will sag slightly under the influence of its own gravity and the pressure of the upper material at the position where it is not supported on the roller surface. At this time, it is difficult for the anti-spill skirt plate to fit tightly with the belt surface. When the fit is too tight, there will be an increase in frictional resistance, affecting the belt transmission efficiency and increasing energy consumption. Although the dust can be isolated by the damping curtain to reduce the diffusion of dust and block the dust inside the feed chute, improving the efficiency of subsequent dust suction and dust removal, the bottom end of the curtain is in contact and friction with the material surface for a long time, resulting in serious wear and relatively short service life. Over time, the gap between the curtains will increase and the dust blocking effect will decline. Summary of the Invention

[0004] The purpose of the present invention is to provide a dust removal device for a transfer station feed chute that is convenient for improving the sealing efficiency between the feed chute and the belt while improving the service efficiency of the curtain, so as to solve the problems raised in the above background art.

[0029] Please refer to Figures 1 - 10The present invention provides a technical solution: a dust removal device for a material guide trough 2 of a transfer station, comprising a base 1, a sealing mechanism 5, a curtain mechanism 7 and a material guide trough 2, wherein a belt 3 is arranged on the base 1, and a conveying member 4 for conveying the belt 3 is arranged on the base 1, wherein the conveying member 4 comprises a plurality of fixing frames 40 fixedly mounted on the base 1, and a plurality of rollers 41 are rotatably connected to the fixing frames 40, and the surfaces of the rollers 41 are in contact with and roll with the belt 3, and a dust removal fan 42 is fixedly connected to the upper side of the material guide trough 2, and the sealing mechanism 5 comprises clamping members 6 installed on both sides of the material guide trough 2, and the clamping members 6 are used to improve the sealing performance with both sides of the belt 3 while reducing the friction resistance of the belt 3 during the transmission process.

[0030] The curtain mechanism 7 includes multiple groups of annular curtains 8 installed in the material guide trough 2. The material guide trough 2 is provided with a driving member 9 for driving the annular curtains 8 to rotate slowly. The curtain mechanism 7 drives the annular curtains 8 to rotate slowly through the driving member 9, thereby changing the position of the bottom end of the annular curtains 8 to avoid continuous wear at a single position. At the same time, the annular curtain design presents a double-layer structure, which can more effectively reduce the dust diffusion effect in the process of being pushed by the material.

[0031] The clamping member 6 includes a guide box 10 installed on the side of the material guide trough 2, a fixed plate 11 is fixedly connected to the guide box 10, and a first transmission belt 12 is slidably connected to the outer wall of the fixed plate 11, a sliding plate 13 is slidably connected to the guide box 10, and a second transmission belt 14 is slidably connected to the outer wall of the sliding plate 13, both ends of the sliding plate 13 and the fixed plate 11 are respectively rotatably connected to multiple groups of rotating shafts 39, the inner walls of the first transmission belt 12 and the second transmission belt 14 are respectively transmission-connected to the outer walls of the multiple groups of rotating shafts 39, an elastic cloth 15 fixedly connected to the edge of the material guide trough 2 is fixedly connected to the upper side of the sliding plate 13, and an adjusting member 16 for adjusting the position of the sliding plate 13 is provided in the guide box 10.

[0032] The driving member 9 includes a driving shaft 17 rotatably connected to the material guide trough 2, and a plurality of groups of partition plates 18 are evenly and fixedly connected to the driving shaft 17. The inner walls of the plurality of groups of annular curtains 8 are transmission-connected to the outer walls of the driving shaft 17, and the plurality of groups of annular curtains 8 are evenly distributed between adjacent partition plates 18. The material guide trough 2 is provided with a rotating member 19 for driving the plurality of groups of driving shafts 17 to rotate synchronously. The rotating member 19 includes a driving motor 37 fixedly mounted on the side of the material guide trough 2. The model of the driving motor 37 is preferably YYHS-40. The output end of the driving motor 37 is coaxially and fixedly connected to one end of any group of driving shafts 17. A synchronous belt 38 is transmission-connected between the plurality of adjacent driving shafts 17. A pushing member 20 for maintaining the contact strength between the annular curtain 8 and the driving shaft 17 is provided in the material guide trough 2.

[0033] The adjusting member 16 includes mounting brackets 21 fixedly installed on both sides of the material guiding groove 2. The mounting brackets 21 are fixedly connected to the fixed bracket 40. A gas storage box 22 is fixedly connected to the mounting brackets 21. A tension spring 23 fixedly connected to the guiding box 10 is fixedly connected to the sliding plate 13. A push rod 24 is fixedly connected to the sliding plate 13. A delivery pipe 25 is connected to the side of the gas storage box 22 in a communicating manner. One end of the push rod 24 is slidably connected to the inner wall of the delivery pipe 25. The end of the delivery pipe 25 close to the gas storage box 22 is designed as a flexible pipe. An inflation member 26 for inflating the gas storage box 22 during the rotation of the drive shaft 17 is provided on the drive shaft 17.

[0034] The inflation member 26 includes an inflation box 27 fixedly installed on the mounting bracket 21. An inflation plate 28 is slidably connected in the inflation box 27. One end of the drive shaft 17 is rotatably connected at a non - central position to a connecting rod 29. The connecting rod 29 is rotatably connected to the upper side of the inflation plate 28. The bottom of the inflation box 27 is connected to the gas storage box 22 through a one - way valve 30. The one - way valve 30 is used to control the one - way delivery of gas from the inflation box 27 to the gas storage box 22. A one - way intake valve 31 for controlling the one - way intake of gas from the outside into the inflation box 27 is fixedly connected to the inflation box 27. A control valve 36 for controlling the air pressure intensity in the gas storage box 22 is provided on the side of the gas storage box 22.

[0035] The pushing member 20 includes a plurality of fixed cylinders 32 fixedly installed in the material guiding groove 2. A lifting frame 33 is slidably connected in the fixed cylinder 32 along the vertical direction. A return spring 34 fixedly connected to the fixed cylinder 32 is fixedly connected to the top of the lifting frame 33. A roller 35 is rotatably connected to the lifting frame 33. The outer wall of the roller 35 is in rolling contact with the upper outer wall of the annular curtain 8.

[0036] In this implementation, during the installation of the material guiding groove 2, the mounting brackets 21 on both sides are connected and fixed to the fixed bracket 40. The two ends of the guiding box 10 are controlled so that the first transmission belt 12 and the second transmission belt 14 are respectively on both sides of the edge of the belt 3. At this time, due to the pulling of the tension spring 23, the distance between the first transmission belt 12 and the second transmission belt 14 is relatively large, which is convenient for placing them in the appropriate position. After placing the guiding boxes 10 on both sides, the installation is completed.

[0037] After that, during the process of the belt 3 transporting materials, the drive motor 37 is started to drive the drive shaft 17 to rotate slowly. The drive shaft 17 drives the annular curtain 8 to move slowly, switching the position of the bottom end of the annular curtain 8. During the transportation of the materials, the materials will be in contact with and rub against one side of the annular curtain 8, pushing the annular curtain 8 to an inclined state until the materials pass through the position below the annular curtain 8. During this process, the dust will be blocked by the annular curtain 8, reducing the flow rate and preventing it from directly diffusing from the inside of the material guiding groove 2 to the outside. The dust removal fan 42 provided inside the material guiding groove 2 can extract the relatively static dust inside, improving the dust removal efficiency.

[0038] The diameter of the driving shaft 17 is 5-10cm, so that each group of annular curtains 8 are in the shape of two bundles of curtains in the vertical direction, and there is a certain distance between the two bundles of curtains, ensuring that when the annular curtains 8 are pushed by the material, the upper side of the annular curtains 8 can still maintain the blocking state of the two bundles of curtains, thereby improving the dust blocking efficiency. At the same time, the pushed annular curtains 8 can maintain one side within a certain inclination angle to be relatively closely fitted with the adjacent annular curtains 8, thereby avoiding the rapid spread of dust. The rotating design of the annular curtains 8 can effectively switch the position of wear between the bottom of the annular curtains 8 and the material, thereby avoiding the problem of short service life of the curtains due to continuous wear at a single position. At the same time, the bottom ends of the annular curtains 8 have a certain curvature on both sides, thereby reducing the friction between the material to a certain extent.

[0039] In the process of the driving shaft 17 driving the annular curtain 8 to rotate, since the outer walls of the annular curtain 8 at different positions have different degrees of wear, a plurality of groups of rollers 35 are used to respectively resist the tops of different annular curtains 8, thereby ensuring that the tops of each group of annular curtains 8 can be resisted downward by the reset spring 34 and the roller 35, thereby increasing the transmission force between the outer wall of the driving shaft 17, so that the driving shaft 17 can continuously and stably drive the annular curtain 8 to rotate slowly.

[0040] During the rotation of the drive shaft 17, the connecting rod 29 will be driven to rotate, and the connecting rod 29 will drive the inflation plate 28 to perform piston lifting and lowering in the inflation box 27, so that the external gas is drawn into the inflation box 27 through the one-way air inlet valve 31, and then pressurized and delivered to the gas storage box 22 through the one-way valve 30. The parameters of the control valve 36 are set in advance, and the maximum air pressure value in the gas storage box 22 is adjusted so that when the air pressure in the gas storage box 22 is greater than the set value, the gas is automatically discharged to the outside through the control valve 36 to prevent the air pressure in the gas storage box 22 from continuing to rise. When the air pressure in the gas storage box 22 increases, the gas pushes the push rod 24 to slide through the delivery pipe 25, so that the sliding plate 13 drives the second transmission belt 14 to slide along the guide box 10, and the second transmission belt 14 gradually fits the upper surface of the belt 3 until the first transmission belt 12 and the second transmission belt 14 respectively tightly clamp the two sides of the belt 3.

[0041] During the clamping process, the tension spring 23 is stretched. At the same time, the sliding plate 13 drives one end of the elastic cloth 15 to move and stretch, ensuring the sealing between the sliding plate 13 and the side wall of the guide groove. After the first transmission belt 12 and the second transmission belt 14 clamp the belt 3, the edge position of the belt 3 can be clamped into a relatively flat state at this time, with a smaller gap, which can effectively prevent dust from overflowing from the side gap. At the same time, the first transmission belt 12 and the second transmission belt 14 can be driven by the belt 3 to rotate around the outer wall of the rotating shaft 39. At this time, the transmission state friction between the belt 3 and the surfaces of the first transmission belt 12 and the second transmission belt 14 is small, greatly reducing the friction coefficient during the contact sealing process and reducing energy consumption.

[0042] This device can automatically clamp and seal both sides of the belt 3 without manually adjusting the positions of the first transmission belt 12 and the second transmission belt 14, and the operation is efficient and convenient. At the same time, after the drive shaft 17 stops rotating, the air pressure in the air storage box 22 no longer changes, and the positions of the first transmission belt 12 and the second transmission belt 14 remain unchanged. When the material guiding groove 2 needs to be removed, the gas in the air storage box 22 is directly released, and the tension spring 23 pulls the sliding plate 13 and the second transmission belt 14 upward, and the clamping state can be automatically released. The equipment is convenient for disassembly and assembly, can be applied to belts 3 of different thicknesses, and at the same time, the position of the guide box 10 is flexible, and can install the edge positions of belts 3 with different inclination angles.
