Description

Technical Field

[0001] This invention relates to the field of conveyor belt impurity removal, and in particular to an impurity removal device for preventing conveyor belt tearing. Background Technology

[0002] Belt conveyors are simple in structure, easy to maintain, energy-efficient, and have low operating costs. They are widely used and are commonly used material conveying equipment in coal plants, raw material yards, and other locations. During material transport, impurities generated during mining operations and the overall transportation chain are mixed with coal or other bulk materials. When these impurities and bulk materials reach the head of the belt conveyor for unloading, they impact the conveyor belt, easily causing it to jam and tear, even while the conveyor is still running. Replacing or repairing the conveyor belt requires a significant amount of time, rendering the conveyor unusable and directly impacting production. Simultaneously, a large amount of coal accumulates at the bottom of the belt conveyor, increasing the workload for cleaning personnel. Therefore, a conveyor belt tear prevention and impurity removal device is proposed. Summary of the Invention

[0029] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0030] Example 1

[0031] Reference Figure 1 This embodiment provides a debris removal device for preventing conveyor belt tearing.

[0032] The conveyor belt anti-tear cleaning device includes a cleaning mechanism 100.

[0033] Specifically, the impurity removal mechanism 100 includes a base 101. Two sets of supports 102 are symmetrically arranged on the rear surface of the base 101, with two supports in each set. The top of the four supports 102 is supported by a top plate 103. Meanwhile, a magnetic separator assembly 104 is installed on the inner side of the supports 102. The magnetic separator assembly 104 can magnetically attract and remove metal impurities in the coal.

[0034] It also includes a mounting platform 105 located at the front of the surface of the base 101. The mounting platforms 105 are symmetrically mounted on the base 101, and motors 106 are fixedly placed on the surfaces of both mounting platforms 105. The output ends of the motors 106 are connected to transmission components 107 through couplings. A screening component 108 is installed between the two transmission components 107. A conveyor component 110 is also installed inside the screening component 108.

[0035] Furthermore, the transmission component 107 includes a rotating column 107a, and the surface of the rotating column 107a is provided with a groove 107b.

[0036] The screening component 108 includes a horizontally arranged screening cylinder 108a, which is located on a conveyor belt between two rotating columns 107a. The top and bottom of the screening cylinder 108a are respectively provided with an upper opening 108b and a lower opening 108c. Connecting rods 108d are fixedly connected to both sides of the screening cylinder 108a. Drive rings 108e are fixedly connected to the outer sides of the two connecting rods 108d. The two drive rings 108e are respectively sleeved on the rotating columns 107a. A drive block 108f is integrally provided on the inner wall of each drive ring 108e. Discharge ports 108g are also provided on both sides of the bottom of the screening cylinder 108a.

[0037] The conveying component 110 includes a rotating rod 110a arranged laterally inside the screening cylinder 108a. Two sets of blades 110b are symmetrically arranged on the outside of the rotating rod 110a. A transmission tooth 110c is coaxially arranged at one end of the rotating rod 110a. A small tooth 110d is meshed with the outer side of the transmission tooth 110c. The small tooth 110d is rotatably mounted on the inner wall of one end of the screening cylinder 108a. A window is also opened on the outer wall of the screening cylinder 108a to expose the small tooth 110d. At the same time, an inner tooth ring 110e is meshed with the outer side of the small tooth 110d. The inner tooth ring 110e is fixed to the inner side wall of one end of the tilting frame 109a.

[0038] Furthermore, the transmission gear 110c, the small gear 110d, and the inner gear ring 110e mesh in pairs. Thus, when the tilting frame 109a rotates, the inner gear ring 110e on its inner sidewall drives the small gear 110d to rotate. Through the transmission of the small gear 110d, the transmission gear 110c drives the rotating rod 110a to rotate with the tilting frame 109a. At the same time, the blades 110b on the rotating rod 110a can push impurities when rotating. Thus, through the two sets of symmetrically arranged blades 110b on the rotating rod 110a, when the rotating rod 110a rotates, the two sets of oppositely arranged blades 110b can push the impurities to both sides of the screening cylinder 108a, achieving the purpose of discharging the impurities from both sides, thereby realizing the automatic discharge of screened impurities and ensuring the normal use of the screening cylinder 108a.

[0039] Preferably, the groove 107b is arranged in an undulating closed configuration along the circumference of the rotating column 107a. Simultaneously, the driving block 108f on the inner wall of the driving ring 108e is slidably embedded inside the groove 107b. Thus, when the motor 106 drives the rotating column 107a to rotate, the driving block 108f slides within the groove 107b due to the push from the groove wall. With the connection and fixation between the two driving rings 108e and the screening cylinder 108a, the two driving rings 108e can synchronously reciprocate and rise and fall with the rotation of the rotating column 107a. This allows the screening cylinder 108a to be lifted, enabling it to reciprocate up and down. During coal transport, coal can enter the screening cylinder 108a through the upper opening 108b for screening when it is at its lowest point. As the screening cylinder 108a gradually rises, the cleaned coal falls through the lower opening 108c and continues to be transported, while impurities remain inside the screening cylinder 108a for later discharge. This process effectively removes non-metallic impurities from the coal, preventing the conveyor belt from tearing and becoming unusable due to debris jamming, and ensuring the normal transport of coal by the conveyor belt.

[0040] It should be noted that the width of the upper opening 108b is greater than that of the lower opening 108c, so that both large impurities and coal can enter the screening cylinder 108a through the upper opening 108b. The setting of the lower opening 108c being smaller than the upper opening 108b can intercept large impurities, allowing only coal to fall out and continue to be conveyed. This achieves the screening and separation between impurities and coal, and in conjunction with the iron remover assembly 104, achieves the purpose of removing both metallic and non-metallic impurities from the coal.

[0041] Example 2

[0042] Reference Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0043] The impurity removal mechanism 100 also includes a rummaging component 109 fitted outside the screening component 108.

[0044] Specifically, the flipping component 109 includes a flipping frame wrapped around the screening cylinder 108a. The surface of the flipping frame is arranged in a circular array with multiple sets of levers 109b. Both ends of the flipping frame are fixedly provided with driven bevel teeth 109c. The outer sides of the two driven bevel teeth 109c are engaged with active bevel teeth 109d. The inner walls of the active bevel teeth 109d are fixedly provided with locking blocks 109e.

[0045] Furthermore, the active bevel gear 109d is also sleeved on the outside of the rotating column 107a. A locking groove 107c is also provided on the surface of the rotating column 107a away from the U-shaped groove 107b. The locking block 109e is located within the locking groove 107c. Through the embedded setting of the locking block 109e, the active bevel gear 109d can rotate synchronously with the rotating column 107a. Simultaneously, the bottom of the active bevel gear 109d is movably embedded in the drive ring 108e. This allows the active bevel gear 109d to rise and fall synchronously with the drive ring 108e and rotate synchronously with the rotating column 107a when the rotating column 107a rotates. Furthermore, the vertical setting of the locking groove 107c ensures that the active bevel gear 109d remains in contact with the rotating column 107a when rising and falling with the drive ring 108e. The synchronous rotation between the active bevel teeth 109d and the driven bevel teeth 109c is required to ensure constant meshing. Under the transmission of the driven bevel teeth 109c, the flipping frame can always flip outside the screening cylinder 108a during reciprocating lifting and screening. Through the lever 109b set on it, the metal and non-metal impurities in the coal are flipped out. As the lever 109b rotates, the impurities are brought to the upper opening 108b of the screening cylinder 108a. The metal impurities are adsorbed by the iron removal component 104, while the non-metallic impurities fall into the screening cylinder 108a. The setting of the flipping component 109 further improves the screening efficiency of the screening cylinder 108a for impurities, while reducing the leakage of impurities in the coal and optimizing the impurity removal effect of the device.

[0046] Example 3

[0047] Reference Figure 5 This is the third embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0048] It also includes a detection mechanism 200, which includes a camera component 201, an image data analysis module 202, a magnetic field shielding component 203, and a metal detection component 204, which are fixed sequentially on the bracket 102.

[0049] The metal detection component can detect exposed iron parts, as well as exposed or buried metal parts in bulk cargo, give an alarm and联动切断输送机电动滚筒电源. The sensitivity of the metal detection component is ≥ 40mm and the sensitivity can be adjusted. Small metal objects triggering the alarm linkage can be ignored to avoid frequent triggering of the alarm linkage to cut off the power supply of the conveyor electric drum and affect the normal operation of the equipment.

[0050] The magnetic field shielding component 203 is installed between the metal detection component 204 and the iron remover component 104 to prevent the metal detection component 204 from being interfered by the magnetic field of the iron removal device.

[0051] The camera component 201 can cooperate with the image data analysis module 202. When the camera component 201 detects a large hard object on the output conveyor belt and gives an alarm, through the comparison and analysis judgment of the image data analysis module 202 with the graphic database, if it is a hard object and its external dimension is large, with a length exceeding 30MM, it is judged as an abnormal hard object. At this time, the power supply of the conveyor electric drum can be联动切断输送机电动滚筒电源, which can directly prevent sundries in bulk cargo from tearing the conveyor belt or early detection of conveyor belt tearing to avoid further expansion of the accident.

[0052] The impurity removal device for conveyor belt anti-tearing is mostly set at both ends of the conveyor, and multi-conveyor process linkage can be achieved. It can also be arranged in a multi-point distributed array, with a detection distance of 30 - 50 meters interval. The remote control function can be used to achieve intelligent multi-machine linkage of the overall conveying system on the switch of the bulk cargo conveying centralized control center. Realize real-time upload of various on-site parameters and store them in the SIS platform management system for easy maintenance analysis and event tracing, further improving the automatic control of the conveyor transportation system.
