Description

Technical Field

[0001] The invention relates to the technical field of equipment for preventing dust from overflowing a conveyor, and in particular to a dust removal device for a material guide chute of a transfer station. Background Art

[0002] At present, the commonly used dust removal methods for the closed guide trough of the steel mill belt conveyor are air circulation dust removal and damping curtain dust removal. The closed guide trough is generally fitted with the belt surface through the anti-overflow skirts on both sides to prevent the material dust on the belt from overflowing through the gap between the guide trough and the belt. In order to reduce the resistance during the belt transmission process, multiple sets of rollers are generally used to support the bottom surface of the belt.

[0003] However, there is a certain gap between the rollers on the existing belt conveyor. The belt will sag slightly due to its own gravity and the pressure of the material on the upper side at the unsupported position on the roller surface. At this time, the anti-overflow skirt is difficult to fit tightly with the belt surface. When the fit is too tight, the friction resistance will increase, affecting the belt transmission efficiency and increasing energy consumption. Although isolating dust with damping curtains can reduce the spread of dust, block the dust inside the material guide trough and improve the efficiency of subsequent dust removal, the bottom end of the curtain is in long-term contact and friction with the material surface, causing severe wear and tear. The service life is relatively short, and long-term use is prone to increase in the gaps between the curtains and reduced dust blocking effects. Summary of the invention

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.

[0023] The adjusting member 16 includes a mounting frame 21 fixedly mounted on both sides of the material guide trough 2, the mounting frame 21 is fixedly connected to the fixing frame 40, an air storage box 22 is fixedly connected to the mounting frame 21, a tension spring 23 fixedly connected to the guide box 10 is fixedly connected to the sliding plate 13, a push rod 24 is fixedly connected to the sliding plate 13, a conveying pipe 25 is connected to the side of the air storage box 22, one end of the push rod 24 is slidably connected to the inner wall of the conveying pipe 25, and one end of the conveying pipe 25 close to the air storage box 22 is designed as a hose, and an inflatable member 26 for inflating the air storage box 22 during the rotation of the driving shaft 17 is provided on the driving shaft 17.

[0024] The inflatable component 26 includes an inflatable box 27 fixedly mounted on the mounting frame 21, an inflatable plate 28 is slidably connected inside the inflatable box 27, a connecting rod 29 is rotatably connected to one end of the driving shaft 17 at a non-center position, the connecting rod 29 is rotatably connected to the upper side of the inflatable plate 28, the bottom of the inflatable box 27 is connected to the gas storage box 22 via a one-way valve 30, the one-way valve 30 is used to control the one-way delivery of gas from the inflatable box 27 to the gas storage box 22, a one-way air inlet valve 31 is fixedly connected to the inflatable box 27 to control the one-way gas to be drawn into the inflatable box 27 from the outside, and 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.

[0025] The pusher 20 includes a plurality of fixed cylinders 32 fixedly installed in the material guide trough 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, and the outer wall of the roller 35 rolls in contact with the upper outer wall of the annular curtain 8.

[0026] In this embodiment, during the installation of the material guide trough 2, the mounting frames 21 on both sides are connected and fixed to the fixing frames 40, and the two ends of the guide box 10 are controlled so that the first transmission belt 12 and the second transmission belt 14 are respectively located 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 larger, which makes it convenient to place them in a suitable position. After the guide boxes 10 on both sides are placed, the installation is completed.

[0027] Afterwards, during the process of conveying materials by the belt 3, the driving motor 37 is started, driving the driving shaft 17 to rotate slowly, and the driving shaft 17 drives the annular curtain 8 to transmit slowly, switching the position of the bottom end of the annular curtain 8. During the conveying process, the material will rub against one side of the annular curtain 8 and push the annular curtain 8 to an inclined state until the material passes 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 avoiding direct diffusion from the inside of the material guide trough 2 to the outside. The relatively static dust inside can be extracted by the dust removal fan 42 arranged inside the material guide trough 2, thereby improving the dust removal efficiency.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] During the clamping process, the tension spring 23 is stretched, and at the same time, the sliding plate 13 will drive one end of the elastic cloth 15 to move and stretch, thereby 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 complete the clamping of the belt 3, the edge position of the belt 3 can be clamped in a relatively flat state, and the gap is smaller, 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 first transmission belt 12 and the second transmission belt 14 surface is relatively small, which greatly reduces the friction coefficient in the resistance sealing process and reduces energy consumption.

[0032] The device can automatically clamp and seal the two sides of the belt 3 without manually adjusting the positions of the first transmission belt 12 and the second transmission belt 14. The operation is efficient and convenient. At the same time, when the driving 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 it is necessary to remove the guide trough 2, 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 to automatically release the clamping state. The equipment is easy to disassemble and assemble, and can be suitable for belts 3 of different thicknesses. At the same time, the position of the guide box 10 is flexible, and it can be installed at the edge position of the belt 3 with different inclination angles.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
