Description

Technical Field

[0001] The invention relates to the technical field of conveyor belts, and in particular to an integrated thin-layer conveyor belt for material distribution and conveying. Background Art

[0002] When conveying thin-layer materials, the materials are generally sent to the conveyor belt through the unloading mechanism, and then the materials are sent out through the conveyor belt. In the process of conveying, if it involves the conveying of divided materials, it has certain defects based on the characteristics of the thin-layer conveyor belt and the needs of divided material conveying, such as: First, the conveyor belts usually used for thin-layer transportation have low tension and are often used for short-distance transportation. Their load-bearing capacity is limited to a certain extent. Secondly, when transporting thin layers of materials composed of separated materials, such as coal powder in power plants, it is also necessary to take into account the treatment of impurities and particles in the separated materials. Therefore, when transporting thin layers of separated materials, it is often necessary to integrate screening or sorting mechanisms. After completing this step during the transportation process, the next process can be entered.

[0003] In the existing method, during integrated operations, since the setting of the screening or sorting mechanism often relies on the material's own gravity (or assisted by vibration) for sorting, the conveyor belt needs to be set up into two parts with a height difference, and it is also necessary to cooperate with the corresponding collection mechanism to complete the screening. On the one hand, this combination of screening and conveying will occupy the already tight short-distance conveying space, and on the other hand, it will also increase the conveying burden of the conveyor belt. Once the screening or sorting mechanism (including the collection mechanism) is blocked, it will affect the transmission work of the entire conveyor belt, thereby causing the operation to be interrupted. Secondly, in the transportation of this method, the dust caused by the sorting process will affect the working environment of the conveying area. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the present invention, the sorting mechanism and the conveying mechanism are arranged in an integrated manner, and when the two are operated in an integrated manner, they have their own independence, so that their operations are both related and unrestricted, and it is not easy to cause the shutdown phenomenon caused by material feed blockage in the prior art.

[0021] Specifically, Figure 1 As shown, the present invention provides an integrated thin-layer conveyor belt for material distribution and conveying, comprising a conveyor belt body 10 and a material discharge channel 20, wherein the conveyor belt body 10 forms a turning point at the outlet of the material discharge channel 20 through the support of a material distribution roller 12, and a material guide channel 21 and a material distribution mechanism 30 are integrated in the material discharge channel 20, wherein the material distribution mechanism 30 is arranged on the side of the material guide channel 21, and forms a disturbance zone 201 with a double channel with the material guide channel 21; The conveyor belt body 10 forms a two-way material guide structure with the turning point as the dividing point, wherein the conveyor belt body 10 is divided into a conveying short side 111 and a conveying long side 112 with the turning point as the dividing point, the conveying short side 111 is tilted downward in the opposite direction of the conveying direction to form a reverse guide structure, and the conveying long side 112 is tilted downward in the conveying direction to form a forward guide structure; Among them, the material guide channel 21 is provided with an interlayer cavity with an adjustable gap for a single layer of material to pass through through a clamping plate. The material enters the disturbance zone 201 through the interlayer cavity to form a thin layer. The thin layer of material is separated from impurities by lateral air supply from the dividing mechanism 30 and falls onto the conveyor belt body 10 to form a thin layer. It is disturbed by the dividing roller 12 and enters the conveying short side 111 and the conveying long side 112 respectively to complete the dividing and conveying.

[0022] The present invention arranges an integrated structure at the feed end of the conveyor belt, and forms a conveying mechanism with particle size sorting with a vertical distribution structure, thereby reducing the modification of the thin-layer conveying mechanism and the space occupied. In the process of unloading, a disturbance zone is set to separate by air flow disturbance to isolate dust. In the further conveying process, by improving the thin-layer conveying structure of the conveyor belt, materials of different qualities are separated in both directions, thereby achieving the purpose of enhancing the particle size sorting effect.

[0023] A vertical unloading channel 20 is formed at the feeding place, which is beneficial to reducing the occupied conveying space. The materials are sorted in the disturbance zone 201 by the material sorting mechanism 30, and the sorted materials can be transported in two directions during the unloading process, which is convenient for collecting impurities removed during the sorting process, so that the materials fall to the conveyor belt body 10 after sorting and enter the conveying process, which is beneficial to reducing the impact on the conveying process and further reducing the situation that the overall conveying process is affected by blockage or failure; After the material is sorted in the disturbance zone 201 and falls onto the conveyor belt body 10, the secondary disturbance of the dividing roller 12 at the turning point helps the qualified material to enter the forward guiding conveying process through the conveying long side 112, and separates the unqualified material, so that it enters the reverse guiding process through the conveying short side 111 to be eliminated, thereby enabling the material to be further sorted, reducing the residual impurities and unqualified materials from entering the conveying process, and enhancing the material sorting effect.

[0024] like Figure 1 As shown, the material is sorted by particle size after passing through the disturbance zone 201 with dual channels, and the qualified material falls directly onto the conveyor belt body 10 through the guide channel 21, and is driven by the bidirectional guide structure of the conveyor belt body 10 to be guided in the forward direction and the reverse direction; Among them, the qualified materials falling on the conveying long side 112 are directly conveyed by the conveying long side 112 in a forward-guided manner; Unqualified materials falling on the conveying short edge 111 are guided in the reverse direction by the limiting rollers 14 arranged above the conveying short edge 111 and removed.

[0025] The material is disturbed by the material separation mechanism 30 in the disturbance interval 201, and the material is disturbed and separated in the falling process. The degree of disturbance is adjusted by the material separation mechanism 30, and the impurities or the material with smaller mass in the material are separated and transported separately from the part of the material, and the material is discharged through the dual channels; like Figure 1 The middle arrow indicates the dual-channel conveying direction. After a disturbance, part of the material (in the direction of the downward arrow) directly falls onto the conveyor belt body 10, and impurities or materials of smaller mass (in the direction of the left arrow) are removed from the left side.

[0026] like Figure 1 and Figure 2 As shown, a limiting roller 14 is provided on the conveying short side 111, and the length direction of the limiting roller 14 covers the width direction of the conveying short side 111. The limiting roller 14 rotates clockwise around its axis and moves the unqualified materials falling on the conveying short side 111 to the reverse guiding structure for delivery; Among them, at least three groups of isolation brushes 141 are arranged at equal intervals on the outer wall of the limiting roller 14. The longitudinal section of the isolation brush 141 is an arc-shaped structure. The isolation brush 141 rotates clockwise and its concave side movably contacts with the conveying short side 111 to increase friction with the material.

[0027] The limiting roller 14 is used to isolate the short conveying side 111, which helps to prevent larger mass materials from falling from the short conveying side 111. During the rotation of the limiting roller 14, smaller mass materials or debris and dust are separated through friction, reducing the dust and debris remaining on the surface of the conveyor belt body 10.

[0028] When the limiting roller 14 rotates, at least three groups of isolation brushes 141 continuously rotate and rub the surface of the conveying short edge 111. When at least three groups of isolation brushes 141 contact the surface of the conveying short edge 111, the concave surface of the isolation brush 141 helps to move the waste and guide it in the reverse direction to remove it.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, one end of the material distribution roller 12 and the limiting roller 14 is connected to the same driving mechanism 15; The driving mechanism 15 includes a driving motor 151, a driving wheel 152, a material distribution roller 153, a limiting roller 154 and a first belt 155. The driving shaft of the driving motor 151 is connected to the driving wheel 152, the material distribution roller 153 and the limiting roller 154 through the first belt 155. The material distribution roller 153 is connected to the material distribution roller 12 through the material distribution roller shaft rod 122. The limiting roller 154 is connected to the limiting roller 14 through the limiting roller shaft rod 142. Among them, the dividing roller 12 is connected to the upper adjustment plate 16 arranged on the conveyor belt body 10 through the dividing roller shaft 122, and connecting rods 161 are arranged at both ends of the upper adjustment plate 16. One end of the connecting rod 161 is provided with a bearing 162 which is sleeved on the outer wall of the dividing roller shaft 122. The upper adjustment plate 16 and the dividing roller 12 are arranged parallel to each other, and the lower surface of the upper adjustment plate 16 is movably abutted against the upper surface of the conveyor belt body 10 to form an isolation structure.

[0030] The material distribution roller 12 and the limiting roller 14 are synchronously driven by the driving mechanism 15, which is beneficial to reducing the driving device and cost and achieving the purpose of synchronous driving.

[0031] The driving motor 151 drives the driving wheel 152 to rotate, and the first belt 155 connects the material dividing roller 153 and the limiting roller 154 to drive the material dividing roller 12 and the limiting roller 14 to rotate synchronously.

[0032] The dividing roller 12 is movably connected to the upper adjustment plate 16. During the rotation of the dividing roller 12, the upper adjustment plate 16 is in a relatively static state. The upper adjustment plate 16 is on the upper conveyor belt close to the conveying long side 112, and the height of the upper adjustment plate 16 is only enough to block materials and debris of smaller mass, which is beneficial to control the debris from entering the conveying long side 112, thereby improving the sorting effect.

[0033] like Figure 1 and Figure 2 As shown, the angle between the conveying short side 111 and the conveying long side 112 is an obtuse angle, and the lowest point of the conveying short side 111 is higher than the lowest point of the conveying long side 112, so that the conveyor belt body 10 is tilted downward along the conveying direction as a whole.

[0034] The obtuse angle structure formed by the conveying short side 111 and the conveying long side 112 facilitates further separation of the materials when they fall, and cooperates with the one-way conveying of the upper conveyor belt to facilitate separation of materials of different qualities at the obtuse angle, thereby further completing the particle size sorting of the materials; The material falls to the turning point of the conveyor belt body 10, and a certain height of obstruction is formed by the upper adjustment plate 16, wherein the qualified material enters the conveying process through the conveying long side 112, and the upper adjustment plate 16 blocks the small-mass material and impurities remaining in the material from entering the conveying long side 112, and at the same time, the friction of the small-mass material and impurities is increased through the disturbance of the material distribution roller 12, so that they fall to the conveying short side 111; The materials and impurities with a relatively small mass that fall onto the conveying short side 111 increase the friction on the waste materials on the conveying short side 111 through the limiting roller 14, thereby driving the waste materials on the conveying short side 111 to be removed through reverse guidance.

[0035] Cooperating with the inclination angle of the conveyor belt body 10 is beneficial to increasing the conveying speed of materials with larger mass and slowing down the conveying speed of materials with smaller mass. According to actual needs, the discharge port is set close to the conveying short side 111 or the conveying long side 112, so as to facilitate further separation of the materials.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, a power assist component 13 coaxially installed with the dividing roller 12 is provided in the dividing roller 12, and the power assist component 13 reciprocates along the length direction of the dividing roller 12 and movably contacts with the conveyor belt body 10 to form a friction structure; At least four groups of convex strips 121 are arranged at equal intervals on the surface of the material distribution roller 12, and the combined shape of the at least four groups of convex strips 121 is distributed in a sawtooth shape in longitudinal section; Among them, the power-assisting component 13 includes a two-way cylinder 131, a fixed rod 132 and a movable bar 133. The movable end of the two-way cylinder 131 is connected to the movable bar 133 through the fixed rod 132. The length direction of the movable bar 133 is arranged parallel to the length direction of the convex strip 121, and two groups of oppositely arranged convex strips 121 are provided with movable grooves matching the movable bar 133. The movable bar 133 is accommodated in the movable groove, and the upper surface of the movable bar 133 is not lower than the upper surface of the convex strip 121.

[0037] The friction of the upper conveyor belt is increased by the dividing roller 12, and the friction degree and direction are further adjusted in cooperation with the power assist component 13, which is beneficial to increase the shaking of the material, thereby helping to further separate materials of different qualities.

[0038] The material separation roller 12 is arranged at the connection between the short conveying side 111 and the long conveying side 112, which is beneficial to accelerate the separation during the material unloading process.

[0039] During the rotation of the dividing roller 12, the movable bar 133 is driven to reciprocate by the bidirectional cylinder 131, which is beneficial to increase the lateral friction on the dividing roller 12, accelerate the movement of the material, and achieve the purpose of uniform material and assisting in correcting the deviation of the upper conveyor belt.

[0040] like Figure 1 and Figure 7 As shown, the material distribution mechanism 30 has a disturbance bar 31 capable of supplying air into the material guide channel 21, and the air supply direction obliquely cuts into the disturbance interval 201, and the disturbance bar 31 has an air outlet 311 whose length direction distance is equal to the width direction distance of the material guide channel 21, and at least two groups of disturbance bars 31 are arranged along the length direction of the material guide channel 21 and are located in the disturbance interval 201; Among them, an air regulating plate 32 is arranged on the disturbance bar 31, and a disturbance motor 33 is arranged on the disturbance bar 31. The output end of the disturbance motor 33 is connected to the shaft 34 through a coupling. The air regulating plate 32 is movably connected to the disturbance bar 31 through the shaft 34. The air regulating plate 32 rotates around the connection between it and the disturbance bar 31 to form an angle adjustment structure.

[0041] The range of material falling is controlled by the material guide channel 21, so that the material passes through in a thinner and wider manner, thereby cooperating with the longer disturbance bar 31, which is beneficial to separate materials of different masses by wind force during the material falling process, and is beneficial to accelerate the separation process of the material falling in the disturbance interval 201.

[0042] The disturbance motor 33 drives the shaft 34 and the air regulating plate 32 to rotate, which is beneficial to adjusting the size and direction of the air outlet 311, convenient for adjustment according to actual use, and beneficial to adjusting the air outlet size and direction of the disturbance strip 31 at different positions, thereby enhancing the sorting effect.

[0043] like Figure 1 , Figure 5 and Figure 8 As shown, the opening width of the unloading channel 20 decreases from top to bottom, and the unloading channel 20 is connected to the guiding channel 21 to form an integrated structure, and the length direction distance of the guiding channel 21 is smaller than the width direction distance of the conveyor belt body 10; Among them, a material opening adjustment plate 22 is provided at the opening of the material discharge channel 20, and the material opening adjustment plate 22 translates along the surface of the material discharge channel 20 and covers the material discharge port 23 to form an opening adjustment structure; A material distribution port 24 is provided on one side of the material guide channel 21 , and a material discharge channel 25 is provided at the material distribution port 24 of the material guide channel 21 . One end of the material discharge channel 25 is tilted downward to form a double-channel diversion structure, and the longitudinal section of the material discharge channel 25 is a parallelogram structure.

[0044] A double channel is formed in the disturbance zone 201 through the discharge channel 25 and the guide channel 21. Part of the material is continuously discharged through the guide channel 21. After the material passes through the disturbance zone 201, impurities and materials of smaller mass are removed through the discharge channel 25. At the same time, dust generated during the discharge process is discharged together through the discharge channel 25.

[0045] The range of material falling is controlled by the material discharge port 23, so as to facilitate separation of the material in the disturbance zone 201. The size of the material discharge port 23 is further controlled by the material discharge port adjustment plate 22, so as to facilitate adjustment according to the material quality and actual use requirements. At the same time, the material port adjustment plate 22 moves horizontally on the material discharge channel 20. During the movement of the material port adjustment plate 22, it helps the material in the material discharge channel 20 to fall, increases the friction and movement of the material, and reduces the blockage caused by material accumulation. At the same time, the material port adjustment plate 22 rubs the surface of the material discharge channel 20, which helps to reduce the sticky residue of the material, thereby keeping the material discharge channel 20 unobstructed.

[0046] A material distribution port 24 is provided in the material guiding channel 21 to facilitate the discharge of the separated materials in the disturbance zone 201 , and the inclined direction of the material discharging channel 25 is conducive to guiding the material to be discharged for easy collection.

[0047] like Figure 5 , Figure 6 and Figure 8 As shown, a rack 221 is provided on one side of the material opening adjustment plate 22, and an adjustment component 26 connected to the rack 221 is provided on the material discharge channel 20; The adjustment assembly 26 includes an adjustment motor 261, a driving wheel 262, a pulley 263, a second belt 264, a gear shaft 265 and an adjustment gear 266. The driving shaft of the adjustment motor 261 is connected to the driving wheel 262 and the pulley 263 through the second belt 264. The gear shaft 265 penetrates the inner wall of the adjustment gear 266 and is fixedly connected to the pulley 263. The adjusting gear 266 rotates around the axis of the pulley 263 , and the rack 221 meshes with the adjusting gear 266 to slide on the material port adjusting plate 22 to form a translation structure.

[0048] The two groups of material port adjustment plates 22 are simultaneously driven to perform oblique movement on the unloading channel 20 through the adjustment component 26, and the driving wheel 262 is driven to rotate through the adjustment motor 261. The second belt 264 connects the two groups of pulleys 263, driving at least two groups of adjustment gears 266 to rotate. The adjustment gear 266 is meshed with the rack 221 to drive the rack 221 to translate, thereby driving the material port adjustment plate 22 to slide.

[0049] like Figure 1 and Figure 7As shown, the outer wall of the conveyor belt body 10 is provided with a frame 11 for fixing the driving mechanism 15, and a fan 35 is fixedly provided on the frame 11, and the output end of the fan 35 is connected to the disturbance bar 31 through an air delivery pipe 36; Among them, a valve is provided at the connection between the air supply pipe 36 and the disturbance strip 31, and at least two groups of disturbance strips 31 respectively form a weak wind channel and a strong wind channel through the valve. The weak wind channel and the strong wind channel form a double-stage separation structure in the disturbance interval, and the disturbance interval is smaller than the height of the distribution port 24.

[0050] The fan 35 is connected to the disturbance bar 31 through the air supply pipe 36, which is conducive to conveying wind into the disturbance bar 31, and cooperates with the valve to control the wind output of at least two groups of disturbance bars 31. In the disturbance interval, two groups of disturbance bars 31 are used to perform two-stage separation. The weak wind channel is conducive to first separating the floating and dust on the surface of the material, and the strong wind channel is conducive to separating the smaller mass materials, which is conducive to completing the sorting and dust removal operations during the unloading process, reducing dust pollution to the working environment, and helping to keep the transportation process in a relatively clean environment.
