Description

Technical Field

[0001] The present invention relates to the field of belt conveyor related equipment, and in particular to a drum cleaning device for a belt conveyor. Background Art

[0002] A belt conveyor is a commonly used device for bulk material transportation. The conveyor belt conveys materials towards the head drum. The conveyor belt of the belt conveyor winds around the head and tail drums. The upper conveyor belt is used to carry the conveyed materials, and the lower conveyor belt is the return conveyor belt, whose moving direction is opposite to the direction of the load-carrying section of the conveyor belt. When the belt conveyor is operating, there will always be a small amount of materials scattered from the materials conveyed on the load-carrying section of the conveyor belt for some reasons. Some of them will fall onto the return section of the conveyor belt and be sent to each redirecting drum by the return section of the conveyor belt. Especially at the redirecting drum, although a set of empty-section cleaner is configured in front of the redirecting drum to clean the accumulated materials on the return conveyor belt, it is difficult to clean them thoroughly. And some scattered bulk materials are behind the empty-section cleaner, so the configured cleaner has no effect. These materials are finally conveyed by the return conveyor belt to the tail redirecting drum, sandwiched between the conveyor belt and the cylindrical surface of the redirecting drum, and move upward as the redirecting drum rotates until the conveyor belt separates from the surface of the redirecting drum. These sandwiched materials will be thrown out along the moving direction of the conveyor belt with the linear velocity of the drum surface and the speed of the conveyor belt, and finally fall on the surface of the return conveyor belt near the redirecting drum. Then they will be sent to the redirecting drum by the return conveyor belt again and be sandwiched between the drum surface and the conveyor belt. Just like this in a cycle, the materials are repeatedly sandwiched and scattered by the conveyor belt and the drum surface, but cannot be discharged from these areas. With the continuous operation of the belt conveyor, more and more materials conveyed by the return conveyor belt to the drum will accumulate, resulting in more and more coal accumulating at the drum, but it cannot be automatically cleaned. These materials are sandwiched between the conveyor belt and the drum surface, seriously affecting the stable operation of the conveyor belt at the redirecting drum.

[0003] In order to prevent the convolution of coal between the drum and the conveyor belt from causing belt deviation, the current method to solve this problem is to use a slag-discharging drum. For example, the utility model with the publication number CN221274368U discloses a belt conveyor slag-discharging drum, which includes: a bottom plate, a drum frame, a conveying shaft, a fixing rod, a slag-discharging mechanism and a limiting mechanism. Two support rods are fixedly connected to the bottom plate. The drum frame is arranged between the two support rods. A plurality of rotating grooves are formed on the drum frame. A plurality of conveying shafts are provided, and the plurality of conveying shafts are respectively rotatably connected in the plurality of rotating grooves. The fixing rod is fixedly connected between the two support rods. The slag-discharging mechanism is arranged on the fixing rod and is used for discharging and cleaning coal ash and coal slag. The limiting mechanism is arranged on the two support rods and is used for limiting the rotation of the drum frame.

[0004] The surface of the slag discharge drum body adopts a non-continuous cylindrical surface with equally divided strip hollows. A symmetrical conical channel is provided under the drum surface, which can allow the material clamped between the drum surface and the conveyor belt to fall from the hollows on the drum surface into the conical channel and then be guided to the axial ends of the drum along the conical channel. This plays the role of slag discharge, that is, clearing the material, thereby ensuring the stable operation of the conveyor belt on the battlefield of the redirecting drum.

[0005] However, since there are many strip-shaped hollows on the surface of the slag discharge drum, the cylindrical surface of the drum is no longer a continuous cylinder. The conveyor belt will vibrate greatly when passing through the slag discharge drum. This vibration will not only cause the rotating parts of the belt conveyor to be in a vibrating state, but also shorten the service life of adjacent rotating parts on the belt conveyor in severe cases, and cause the possibility of loosening of some fasteners and connectors. In addition, the production cost of the slag discharge drum is relatively high, the process is relatively complicated compared to ordinary drums, and structural cracks have occurred during use. The reliability is relatively poor, and thus the application of the slag discharge drum is limited.

[0006] When a belt conveyor is transporting bulk materials, it is very common for small particles to be caught between the redirecting drum and the conveyor belt. Various types of faults caused by this are endless during the operation of the conveyor, and they are always a common problem when the belt conveyor is transporting bulk materials. If a better solution can be obtained, it will be extremely beneficial to the stable operation of the belt conveyor. Summary of the invention

[0007] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a roller cleaning device for a belt conveyor. The device has no contact with the roller surface but can promptly clean the coal sandwiched between the conveyor belt and the redirecting roller of the belt conveyor, thereby ensuring the safe, stable and normal operation of the conveyor belt on the redirecting roller.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] A roller cleaning device for a belt conveyor is installed in front of a redirecting roller in a conveyor belt of the belt conveyor, the device comprises a baffle shaft, a baffle, an inclined slide plate and a support seat, one end of the baffle is connected to the baffle shaft, both ends of the baffle shaft are connected to the support seat, and the support seat is fixed by an external device; the inclined slide plate is connected to a side surface of the baffle, and there are multiple inclined slide plates, the bottoms of the inclined slide plates located on the left and right sides of the baffle are respectively inclined toward the outside of the baffle, and are symmetrically arranged along the center line of the baffle to form multiple groups of figure eight structures; the baffle is located on the coal throwing trajectory of the redirecting roller of the belt conveyor.

[0010] Furthermore, the conveyor belt comprises a conveyor belt load-bearing section and a conveyor belt return section, and the baffle is located between the conveyor belt load-bearing section and the conveyor belt return section, and is perpendicular to the surface of the conveyor belt return section;

[0011] The redirecting roller is used to rotate the conveyor belt in the return section at the bottom to the load-carrying section of the conveyor belt at the top, and throw the coal carried by the return section of the conveyor belt at the bottom from the top.

[0012] Furthermore, the baffle shaft is parallel to the axis of the roller shaft of the redirecting roller.

[0013] Furthermore, the distance between the surface of the baffle and the surface of the redirecting roller is within the range of 15 to 50 cm.

[0014] Furthermore, the support base includes a triangular bottom plate, and a shaft hole is provided at a corner of the top of the bottom plate. The baffle shaft is matched with the shape and size of the shaft hole and is connected in the shaft hole.

[0015] Furthermore, radially distributed support base positioning holes are provided on the circumferential surface of the shaft hole, and a plurality of radially distributed baffle positioning holes are provided on the circumferences at both ends of the baffle shaft. The support base is connected to the baffle shaft by a pin shaft passing through the support base positioning holes and the baffle positioning holes.

[0016] Furthermore, bolt holes are provided at the top of the bottom plate to fix the support base on the intermediate frame of the belt conveyor through bolts.

[0017] Furthermore, the thickness of the inclined slide plate is within the range of 15 to 20 mm.

[0018] Furthermore, the baffle and the inclined slide plate are made of a metal or non-metal material with a smooth surface and not easily adherent to coal.

[0019] Furthermore, the width of the baffle and the regional length of the inclined slide plate are both greater than the width of the conveyor belt.

[0020] Compared with the prior art, the present invention has the following advantages:

The coal thrown by the roller will be scattered on the inclined slide plates, move a certain distance outward along the inclined slide plates, and then fall onto the return section of the conveyor belt. During the continuous throwing and sliding process, the coal continuously moves towards both ends of the roller and finally automatically moves out of the conveyor belt. This solution has no contact with the roller surface, but can timely clean the coal clamped between the conveyor belt of the belt conveyor and the redirecting roller, so that the conveyor belt always has a good fit with the drum surface of the redirecting roller, thereby ensuring the safe, stable and normal operation of the conveyor belt on the redirecting roller and improving the reliability of the continuous operation of the belt conveyor.

[0023] (3) The working principle of the roller cleaning device for belt conveyors provided by the present invention is relatively simple, but the function is continuously stable, safe and reliable, and can operate for a long time. It can not only be arranged at the tail redirecting roller of the belt conveyor, but also can be arranged and installed at some horizontally or inclined redirecting rollers on the belt conveyor, and can replace the traditional slag discharging roller, making the belt conveyor operate more stably and reliably, but the investment cost is much lower than various solutions adopted by the previous belt conveyors to solve such problems.

[0024] (4) The roller cleaning device for belt conveyors provided by the present invention has the function of cleaning the coal on the return conveyor belt, ensuring the stable operation of the belt conveyor, extending the service life of the belt conveyor, reducing the faults occurring in the belt conveyor, and reducing the maintenance and repair costs.

[0035] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined.

[0036] Embodiment 1

[0037] As Figure 4As shown in the figure, this embodiment provides a roller cleaning device for a belt conveyor, which is installed in front of the inner redirecting roller 1 of the conveyor belt 4 of the belt conveyor. The device includes a baffle shaft 5, a baffle 7, an inclined slide plate 8 and a support seat 9. One end of the baffle 7 is connected to the baffle shaft 5, and both ends of the baffle shaft 5 are connected to the support seat 9, and the support seat 9 is fixed by external equipment; the inclined slide plate 8 is connected to one side surface of the baffle 7. The number of inclined slide plates 8 is multiple. The inclined slide plates 8 located on the left and right sides of the baffle 7 are inclined with their bottoms facing the outside of the baffle 7, and are symmetrically arranged left and right along the center line of the baffle 7, forming multiple groups of inverted V-shaped structures; the baffle 7 is located at the coal throwing trajectory of the redirecting roller 1 of the belt conveyor.

[0038] The width of the baffle 7 and the regional length of the inclined slide plate 8 are both greater than the width of the conveyor belt 4. This can enable the coal thrown by the roller to gradually move to the outside of the conveyor belt and fall out through the inclination of the inclined slide plate.

[0039] The baffle 7 and the inclined slide plate 8 are made of metal or non-metal materials with smooth surfaces and not easy to adhere to coal. The metal material can be stainless steel, and the non-metal material can be polyurethane.

[0040] In this embodiment, as Figure 2 shown, the inclined slide plates 8 are symmetrically arranged left and right along the center line of the baffle 7. Specifically: the number of inclined slide plates 8 on the left side is 8, and there is the same spacing between adjacent two inclined slide plates 8. The bottoms of each inclined slide plate 8 are inclined to the left side of the baffle 7, and the inclination angle is within the range of 15 degrees to 45 degrees. The number of inclined slide plates 8 on the right side is also 8, which is symmetrical with the inclined slide plates 8 on the left side. The specific number of the inclined slide plates 8 arranged should match the width of the conveyor and the inclination angle of the inclined slide plates 8.

[0041] Specifically, as Figure 1 shown, the conveyor belt 4 includes a conveyor belt load-carrying section 401 and a conveyor belt return section 402. The baffle 7 is located between the conveyor belt load-carrying section 401 and the conveyor belt return section 402, and is perpendicular to the surface of the conveyor belt return section 402;

[0042] The redirecting roller 1 is used to rotate the conveyor belt 4 of the bottom conveyor belt return section 402 to the top conveyor belt load-carrying section 401.

[0043] The redirecting roller 1 can be a driving roller of the conveyor belt or a tail redirecting roller of the conveyor belt, as long as it meets the requirement that the roller presses the coal at the bottom of the conveyor belt onto the top of the conveyor belt and throws it out, and has a coal throwing trajectory.

[0044] Preferably, the axis of the baffle shaft 5 is parallel to the axis of the roller shaft 3 of the redirecting roller 1, so that the surface of the baffle is parallel to the surface of the roller, that is, the coal thrown by the roller can vertically fall onto the surface of the baffle.

[0045] For the dimension setting, optionally, the thickness of the inclined slide plate 8 is within the range of 15 to 20 mm.

[0046] The distance between the surface of the baffle 7 and the surface of the redirecting roller 1 is within the range of 15 to 50 cm.

[0047] Preferably, as Figure 3 shown, the support base 9 includes a triangular bottom plate 901. A shaft hole 903 is provided at one corner of the top of the bottom plate 901. The baffle shaft 5 is matched with the shape and size of the shaft hole 903 and is connected in the shaft hole 903. The baffle shaft 5 needs to be fixedly connected to the shaft hole 903 to avoid the shaking of the baffle. The fixed connection method can be bonding, welding, bolt connection or pin connection, etc.

[0048] Optionally, radially distributed support base positioning holes 902 are provided on the circumferential surface of the shaft hole 903, and a plurality of radially distributed baffle positioning holes 6 are provided on the circumferences at both ends of the baffle shaft 5. The support base 9 is connected to the baffle shaft 5 by passing a pin through the support base positioning hole 902 and the baffle positioning hole 6.

[0049] Optionally, bolt holes are provided at the top of the bottom plate 901 to fix the support base 9 to the intermediate frame of the belt conveyor through bolts.

[0050] In this embodiment, the roller cleaning device is installed in front of the tail redirecting roller and is located between the load-carrying section 4-1 and the return section 4-2 of the conveyor belt, close to the tail redirecting roller. The rotation direction 2 of the roller in front of the tail redirecting roller is counterclockwise and is located on the right side of the conveyor belt, which can remove the accumulated coal between the tail redirecting roller and the conveyor belt 4.

[0051] The specific arrangement is as follows: At both ends of the baffle shaft 5, a shaft hole 903 of a support seat 9 is installed respectively. On the circumferential surface on one side of the baffle shaft, several radial through holes are provided, namely baffle positioning holes 6. On the circumferential surface of the shaft hole 903 of the support seat 9, radial through holes are also provided, namely positioning hole support seats 902. These through holes can allow the positioning pin shafts 10 to pass through. When fixing the position of the baffle 7, the positioning hole 6 of the baffle shaft 5 is aligned with the positioning hole 902 on the support seat 9, and then the pin shaft 10 passes through the baffle positioning hole 6 and the positioning hole support seat 902, so that the baffle shaft cannot rotate relative to the shaft hole 903 of the support seat 9. Before positioning, ensure that the baffle is perpendicular to the surface of the return section of the conveyor belt. Several inclined sliding plates 8 are arranged on the surface of the baffle 7. The bottom surface of the inclined sliding plate 8 is fixed on the surface of the baffle 7. The thickness of the inclined sliding block 8 is about 15-20 mm. These inclined sliding plates 8 are arranged symmetrically about the center line of the baffle on the left and right and form an angle with the center line of the baffle. The distance between the surface of the baffle 7 and the surface of the tail redirecting roller 1 is 15-50 cm, ensuring that the coal entrained and spilled between the surface of the roller and the conveyor belt falls on the surface of the baffle 7. There are bolt holes on the bottom plate 901 of the support seat 9, and the support seat 9 can be fixed on the intermediate frame of the belt conveyor through bolts. And the axis of the baffle shaft 5 is parallel to the axis of the tail redirecting roller 1.

[0052] Working principle:

[0053] When the belt conveyor transports materials towards the head of the conveyor, there will always be some materials or foreign objects on the return section 402 of the conveyor belt. The main reasons are as follows:

[0054] 1. Leakage points appear in the feed pipe or chute of the conveyor, and some materials with smaller particle sizes overflow from these leakage points and scatter onto the return conveyor belt of the belt conveyor;

[0055] 2. Abnormal situations occur during the operation of the belt conveyor. For example, the conveyor belt deviates, causing some materials to slide from the load-carrying section 401 of the conveyor belt onto the return conveyor belt;

[0056] These small amounts of scattered coal will fall onto the return section of the conveyor belt and be transported by the return section of the conveyor belt to the tail redirecting roller. As the tail redirecting roller rotates, these small amounts of coal will be clamped between the conveyor belt and the surface of the roller and move in a circular motion along the roller surface. As a result, the clamped coal will rotate to the upper part of the roller. At this time, the surface of the roller and the conveyor belt separate, and the clamped coal will be released and thrown off the roller. However, these coals will again fall onto the return section of the conveyor belt, and the return section of the conveyor belt will send the coal to the tail redirecting roller again to be clamped by the roller surface and the conveyor belt. In this way, these coals can never break away from the conveyor. As the running time increases, the coal accumulated at the tail redirecting roller will become more and more. Coal is a solid and difficult to compress. Therefore, when it accumulates to a certain amount, it will significantly change the rotation profile of the conveyor belt on the surface of the tail redirecting roller, have a greater impact on the normal winding of the conveyor belt at the tail redirecting roller, and cause the conveyor belt to run unstably.

[0057] How to timely remove these coals can ensure the stable operation of the belt conveyor. The present invention relates to a roller cleaning device for a belt conveyor. By arranging it between the return section of the conveyor belt and the carrying belt and near the tail redirecting roller, when the coal clamped between the conveyor belt and the roller surface rotates to the upper part along with the roller, the conveyor belt and the roller separate, and the clamped coal is thrown out. And the baffle of the cleaning device will be arranged at the coal trajectory. These coals will impact on the surface of the baffle 7. An inclined slide plate 8 is arranged on the surface of the baffle 7. These coals will slide along the side surface of the inclined slide plate 8 towards the outside, that is, towards the two circular end faces of the roller. However, the length of the inclined slide plate 8 is limited. The coal can only move a certain distance towards the end face of the roller through one inclined slide plate and then fall onto the return section of the conveyor belt again. These coals will be clamped by the redirecting roller and the belt and rotate towards the upper part of the roller again, and be thrown out again, and be thrown onto the baffle 7 again, and slide down and towards the end face side of the roller along an inclined slide plate adjacent to the previous inclined slide plate. In this way, the coal will rotate with the clamping between the roller and the belt. With the side shifting function of the inclined slide plate on the baffle surface, the coal will continuously move towards the two ends of the tail redirecting roller and finally move out of the conveyor belt, that is, it will no longer be clamped by the conveyor belt and the roller surface. In this way, the coal scattered on the return section of the conveyor belt of the belt conveyor will be cleaned out from the belt. Since the width of the baffle and the length of the area where the inclined baffle is set are larger than the width of the conveyor belt. The coal can be completely and timely cleaned out of the belt conveyor, and more coal cannot accumulate on the surface of the conveyor belt and the roller, and the surface of the roller can also be relatively clean. In this way, the normal and stable operation of the belt conveyor can be ensured.

[0058] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
