Description

Technical Field

[0001] The invention relates to the technical field of material conveying, and in particular to a hydraulic deviation correction device for a dry coke quenching belt and a coke transport system. Background Art

[0002] Coke dry quenching is a process of drying and extinguishing coal. It uses inert gas to cool the red coke so that the dried and extinguished coal can be stored or transported, which can improve the safety of coal storage and transportation, and also improve the combustion efficiency of coal. When using belts for conveying in the continuous production process of coke dry quenching, the belt will deviate due to uneven force during load operation, causing material to fall and affect normal production operations. Usually, a hydraulic deviation correction device is used to correct the belt deflection problem to facilitate the transportation of coke dry quenching.

[0003] The working principle of the current hydraulic deviation correction device is: when the belt deviates, the belt and the detection drive wheel come into contact to cause the detection drive wheel to rotate, and then the detection drive wheel drives the oil pump to output hydraulic oil, and controls the driving cylinder to drive the self-aligning roller to deflect so that the belt always runs within the set range, which is conducive to the normal operation of the belt conveyor.

[0004] Referring to the Chinese patent document with authorization announcement number CN210593770U, a one-way hydraulic deviation correction device is disclosed. The device reduces the possibility of the belt pressing against the roller, causing the roller to get stuck and difficult to continue rotating, thereby affecting the deviation correction performance, by providing a buffer mechanism at the roller.

[0005] With regard to the above-mentioned related technologies, when the belt is in operation, after the belt contacts the inspection and drive wheel, an angle exists between the belt and the inspection and drive wheel, and the edge of the belt will be folded under the influence of the inspection and drive wheel. The belt repeatedly contacts and folds with the inspection and drive wheel, which may easily cause wear and local deformation on the belt surface, thereby reducing the service life of the belt. Summary of the invention

[0006] In view of this, the present invention provides a dry quenching belt hydraulic deviation correction device and a coke transport system, aiming to solve the problem of short belt life caused by easy wear and local deformation of the belt.

[0007] To solve the above technical problems, in the first aspect, the present invention provides a hydraulic deviation correction device for a dry coke quenching belt, comprising a mounting frame, the mounting frame is provided with a deviation correction roller group, the top of the mounting frame is hinged with a rotating frame, the deviation correction roller group consists of a first support roller and two second support rollers, the first support roller is rotatably connected to the rotating frame, the two second support rollers are respectively arranged on both sides of the first support roller, and the opposite ends of the two second support rollers are inclined from bottom to top; the mounting frame is rotatably connected with a detection and driving roller on the side away from the second support roller, the detection and driving roller consists of a conical roller and a cylindrical roller, the maximum diameter of the cross section of the conical roller is larger than the diameter of the second support roller, and the number of the detection and driving rollers corresponds to the number of the second support rollers, and the central axis of the detection and driving roller is parallel to the central axis of the second support roller; the mounting frame is provided with a driving member for driving the mounting frame to rotate in the horizontal direction when the detection and driving roller rotates.

[0008] By adopting the above technical scheme, during the operation of the belt, the setting of the tapered roller of the detection and driving roller can contact the belt after the belt is offset. Compared with the setting of the detection and driving wheel in the prior art, the line contact between the belt and the detection and driving wheel can be changed to the surface contact of the tapered roller, so as to increase the contact area between the belt and the tapered roller, thereby reducing the wear of the belt and the probability of the edge of the belt folding due to excessive offset, which is beneficial to extending the service life of the belt. It takes a certain reaction time for the second support roller to rotate after the detection and driving roller rotates to realize the deviation correction. The setting of the tapered surface of the tapered roller can provide an inward force to the belt when the belt is offset, so as to prevent the instantaneous offset of the belt from being too large and causing the material to be scattered, and then the belt is corrected by the second support roller.

[0009] Optionally, the driving member includes a gear pump connected to the detection and driving roller and a first oil cylinder connected to the gear pump. The rotation of the detection and driving roller is used to provide power for the gear pump. The oil outlet of the gear pump is connected to the oil inlet of the first oil cylinder. The driving shaft of the first oil cylinder is hinged with a support plate fixedly connected to the rotating frame.

[0010] By adopting the above technical solution, when the second support roller needs to be rotated to correct the belt, the detection and drive roller drives the gear pump to run when it rotates, and the gear pump inputs hydraulic oil into the first cylinder, thereby driving the drive shaft of the first cylinder to extend or retract, so as to drive the support plate and the rotating frame to rotate, so that the belt always runs within the set range.

[0011] Optionally, the mounting frame is provided with an adjustment mechanism, and the adjustment mechanism is used to change the angle between the second supporting roller and the detection and driving roller and the mounting frame.

[0012] By adopting the above technical solution, the setting of the adjustment mechanism can change the angle between the second support roller and the mounting frame, that is, it can drive the second support roller to rotate upward. When the second support rollers on both sides rotate upward, they can drive the belt to bend inward, so as to change the groove depth formed by the belt to adapt to the transportation of different materials and the amount of materials in transportation. At the same time, when the belt runs to the edge, it can assist the belt to restore flatness to facilitate the operation of the belt.

[0013] Optionally, the adjustment mechanism includes a second oil cylinder hingedly mounted on the rotating frame and a third oil cylinder hingedly mounted on the mounting frame, the second oil cylinder is used to drive the second support roller to rotate, and the third oil cylinder is used to drive the detection and driving roller to rotate.

[0014] By adopting the above technical solution, when it is necessary to adjust the angle between the second support roller and the mounting frame, the second support roller can be driven to rotate by starting the second oil cylinder to facilitate its adjustment. At the same time, the detection and drive roller is also adjusted by the third oil cylinder so that the central axes of the second support roller and the detection and drive roller are always kept parallel to facilitate the deviation correction of the belt.

[0015] Optionally, the driving shaft of the second oil cylinder is hinged to the first movable frame, the second support roller is rotatably connected to the first movable frame, and the first movable frame is hinged to the rotating frame, the driving shaft of the second oil cylinder is hinged to the second movable frame, the inspection and driving roller is rotatably connected to the second movable frame, and the second movable frame is hinged to the mounting frame.

[0016] By adopting the above technical solution, when the second support roller needs to be rotated, the second oil cylinder is started so that the driving shaft of the second oil cylinder drives the first movable frame to rotate, and the rotation of the first movable frame can drive the second support roller to rotate, so as to facilitate the adjustment of the second support roller; when the inspection and drive roller needs to be rotated, the third oil cylinder is started so that the driving shaft of the third oil cylinder drives the second movable frame to rotate, and the rotation of the second movable frame can drive the inspection and drive roller to rotate, so as to facilitate the adjustment of the inspection and drive roller.

[0017] Optionally, a hinge shaft is fixedly connected to the mounting frame, and the support plate and the rotating frame are both hinged to the hinge shaft.

[0018] By adopting the above technical solution, the setting of the hinge shaft can provide support for the rotating frame and the support plate, improve the stability of the structure, and facilitate the rotation of the rotating frame and the support plate.

[0019] In a second aspect, the present invention provides a dry quenching coke transport system, comprising a dry quenching coke belt hydraulic deviation correction device in the first aspect, and also comprising a conveyor belt for conveying the dry quenched coke.

[0020] By adopting the above technical solution, a coke transport system having a dry quenching coke belt hydraulic deviation correction device can facilitate the transportation of dry quenched coke, extend the service life of the belt and reduce the probability of material scattering.

[0021] Optionally, the number of applications of the dry quenching belt hydraulic deviation correction device can be increased or decreased according to the length of the conveyor belt.

[0022] By adopting the above technical solution, the number of deviation-correcting devices can be selected according to the length of the belt, so as to correct the deviation of the belt and facilitate the transportation of dry quenched coke.

[0023] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects: 1. The setting of the detection and driving roller can change the contact between the detection and driving roller and the belt into surface contact when the belt contacts the detection and driving roller, thereby increasing the contact area between the belt and the detection and driving roller, reducing the wear of the belt and the occurrence of the belt edge folding phenomenon, which is beneficial to prolonging the service life of the belt. At the same time, the setting of the conical surface can provide an inward force to the belt when the belt deviates, so as to prevent the material from being scattered due to excessive instantaneous deviation of the belt; 2. By adjusting the height of the second support roller, the depth of the groove formed by the belt can be changed, which is conducive to conveying different types of materials or adapting to the amount of transported materials. At the same time, when the belt runs to a turn, the second support roller is rotated downward to restore the belt to a horizontal state, thereby facilitating the operation of the belt.

[0026] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 4 , a clear and complete description of the technical solutions of the embodiments of the present invention is given. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0027] In a first aspect, the present invention provides a hydraulic deviation correction device for a dry coke quenching belt.

[0028] Reference Figure 1 , Figure 2 and Figure 3 A hydraulic deviation correction device for a dry coke quenching belt comprises a mounting frame 1, a deviation correction roller group 11, a detection and driving roller 13, and a driving member 2 for driving the deviation correction roller group 11 to rotate in the horizontal direction. A rotating frame 12 is hingedly connected to the top of the mounting frame 1. The deviation correction roller group 11 consists of a first support roller 111 and two second support rollers 112. The first support roller 111 is rotatably connected to the top of the rotating frame 12 and extends in the horizontal direction. The two second support rollers 112 are respectively arranged on both sides of the first support roller 111 and the opposite ends of the two second support rollers 112 are tilted from bottom to top so that the belt forms a groove for accommodating dry coke quenching. The detection and driving roller 13 is rotatably connected to the side of the mounting frame 1 away from the second support roller 112. The detection and driving roller 13 is tilted, and the central axis of the detection and driving roller 13 is parallel to the central axis of the second support roller 112, and the central axis of the detection and driving roller 13 and the second support roller 112 are equal to the angle between the horizontal plane, and the detection and driving roller 13 consists of a tapered roller. 131 and a cylindrical roller 132, and the cylindrical roller 132 is close to the middle position of the mounting frame 1. When the belt deviates, the belt will abut against the conical roller 131. The inclined conical roller 131 can increase the contact area between the belt and the conical roller 131, so as to protect the surface of the belt, which is beneficial to prolonging the service life of the belt and driving the conical roller 131 to rotate. With the rotation of the conical roller 131, the driving member 2 can drive the rotating frame 12 to rotate, so that the first support roller 111 and the second support roller 112 rotate to realize the deviation correction of the belt. The setting of the conical roller 131 can apply an inward force to the belt when the belt deviates and contacts with the belt, so as to prevent the probability of material spillage caused by excessive belt deviation.

[0029] Reference Figure 1 and Figure 2The driving member 2 includes a gear pump 21, a first oil cylinder 22 and a support plate 23. The gear pump 21 is arranged on one side of the detection and driving roller 13. The rotation of the detection and driving roller 13 can drive the gear in the gear pump 21 to rotate. The gear pump 21 is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to transport liquid or increase its pressure. It belongs to the existing technology well known to people in this field and will not be described in detail here. The gear pump 21 is connected to the oil inlet of the first oil cylinder 22. The first oil cylinder 22 is hingedly mounted on the mounting frame 1 and placed horizontally. The support plate 23 is hinged to the drive shaft of the first oil cylinder 22. The rotating frame 12 is fixedly connected to the top of the support plate 23, and the support plate 23 and the rotating frame 12 are both hinged to the mounting frame 1 through the hinge shaft 4. The first oil cylinder 22 drives the support plate 23 and the rotating frame 12 to rotate, which can rotate the second support roller 112 to achieve belt deviation correction.

[0030] Reference Figure 1 and Figure 4 The mounting frame 1 is provided with an adjustment mechanism 3, which is used to change the angle between the second support roller 112 and the detection and drive roller 13 and the mounting frame 1, that is, the adjustment mechanism 3 can adjust the height of the second support roller 112 and the detection and drive roller 13. The adjustment mechanism 3 includes a second oil cylinder 31, a third oil cylinder 32, a first movable frame 33 and a second movable frame 34. The second oil cylinder 31 is hingedly mounted on the rotating frame 12, the first movable frame 33 is hingedly connected to the driving shaft of the second oil cylinder 31, and the second support roller 112 is rotatably connected to the first movable frame 33, the third oil cylinder 32 is hingedly mounted on the mounting frame 1, the second movable frame 34 is hingedly connected to the driving shaft of the third oil cylinder 32, and the detection and drive roller 13 is rotatably connected to the second movable frame 34.

[0031] The implementation principle of a hydraulic deviation correction device for a dry coke quenching belt in an embodiment of the present invention is as follows: during the transportation process of dry coke quenching, when the belt deviates, the belt will contact the conical roller 131. At this time, the conical roller 131 will give the belt an inward force to prevent the belt from deviating too much. Then the belt can rotate the conical roller 131. As the conical roller 131 rotates, the gear pump 21 starts to run and outputs hydraulic oil to the first oil cylinder 22 to make the first oil cylinder 22 reciprocate, thereby driving the support plate 23, the rotating frame 12 and the second support roller 112 to rotate, so as to adjust the belt so that the belt always runs within the set range to facilitate the transportation of dry coke quenching.

[0032] In a second aspect, the present invention further provides a dry quenching coke transport system, comprising a dry quenching coke belt hydraulic deviation correction device in the first aspect, referring to Figure 1 , and also includes a conveyor belt 5 for conveying dry quenched coke. The number of applications of a dry quenching coke belt hydraulic deviation correction device can be increased or decreased according to the length of the conveyor belt 5 to facilitate the deviation correction of the conveyor belt 5.

[0033] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
