Description

Technical Field

[0001] This utility model belongs to the field of conveying and regulating technology, specifically relating to a coal flow regulating guide trough for a belt conveyor in a coal coking system. Background Technology

[0002] In coal coking production systems, belt conveyors are typically an essential piece of equipment for transporting various types of coal. However, during actual coal transport, the continuous accumulation of coal can cause the conveyor belt to deviate or coal to spill off the belt, and the coal flow cannot be kept centered on the conveyor belt, which requires improvement. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a coal flow regulating guide chute for a belt conveyor in a coal coking system, which can effectively guide and center the coal flow and facilitate disassembly and replacement, so as to solve the above problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coal flow regulating guide chute for a belt conveyor in a coal coking system, comprising a belt conveyor and a guide chute located above the feeding end of the belt conveyor. The guide chute consists of a feeding pipe, a discharge pipe located below one side of the feeding pipe with a cross-sectional area smaller than the feeding pipe, and a chute inclined between the bottom end of the feeding pipe and the top end of the discharge pipe, forming a trapezoidal structure that is wider at the top and narrower at the bottom. An installation block is fixedly provided on the upper side of the bottom of the chute, and several blind holes arranged in a rectangular array are provided on both the front and rear sides of the installation block. Below the mounting block is an inverted U-shaped bracket. A positioning box with an open top is fixed on the top of the horizontal part of the bracket. A first hydraulic cylinder is fixed on the top of the horizontal part of the bracket on both the front and rear sides of the positioning box. The piston rod of the first hydraulic cylinder faces the positioning box and is fixedly connected to a limiting plate. Several limiting rods are fixed on the side of the limiting plate near the positioning box. The limiting rods can extend into the positioning box. The mounting block is inserted into the positioning box. The limiting plate abuts against the outer side of the positioning box on the same side. The limiting rods correspond one-to-one with the blind holes on the same side and are inserted into the box.

[0005] Preferably, the mounting block is adapted to the mounting box.

[0006] Preferably, the limiting rod is adapted to the corresponding blind hole.

[0007] Preferably, a support plate is fixedly connected between the two vertical parts of the bracket, a dust collector and an exhaust fan are installed on the support plate, an annular pipe is sleeved on the outside of the feeding pipe, a number of dust collection hoods are connected to the bottom of the annular pipe, the side of the annular pipe near the bracket is connected to the air inlet of the dust collector, and the exhaust port of the dust collector is connected to the air inlet of the exhaust fan.

[0008] Preferably, the bottom left and right sides of the two vertical parts of the bracket are each vertically fixed with a support leg, and an inverted U-shaped support plate made of foam aluminum is fixedly sleeved on the support leg.

[0009] Preferably, the outrigger is a second hydraulic cylinder, and the support plate is fixedly sleeved on the outside of the cylinder body of the second hydraulic cylinder. The piston rod of the second hydraulic cylinder faces downward and a caster is installed on its bottom end. When the piston rod of the second hydraulic cylinder is in the retracted state, the bottom end of the caster is higher than the bottom end of the vertical part of the support plate.

[0010] The beneficial effects of this utility model are as follows: During coal conveying, the coal material can enter from the feed pipe of the guide chute, and then, guided by the chute, converge towards the middle of the belt conveyor. Finally, it is discharged through the discharge pipe to the middle of the belt conveyor, so that the subsequent coal flow can be effectively kept in the center of the conveyor belt, which is more conducive to improving the quality of coal conveying. After long-term use, if the guide chute leaks due to impact wear or other reasons, it can be easily disassembled and replaced. Specifically, with the machine stopped, first run the two first hydraulic cylinders to retract their piston rods, driving the limit plate back until the limit rod is completely pulled out of the positioning box, which releases the insertion limit of the mounting block. Then, move the entire guide chute upward to disassemble the original guide chute. Next, take the new guide trough, align the mounting block on it with the positioning box sleeve, and then operate the two first hydraulic cylinders to extend their piston rods, causing the limiting plate to press against the outside of the positioning box. This allows the limiting rod to be inserted into the corresponding blind hole, securing the mounting block in place, thus completing the fixed installation of the new guide trough. This allows for flexible and convenient assembly and disassembly of the entire guide trough, and facilitates easy replacement in case of leaks, making the overall device more convenient and practical to use.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 7 As shown, a coal flow regulating guide chute for a belt conveyor in a coal coking system includes a belt conveyor 1 and a guide chute 2 located above the feeding end of the belt conveyor 1. The guide chute 2 consists of a feeding pipe 3, a discharge pipe 4 located below one side of the feeding pipe 3 and having a cross-sectional area smaller than the feeding pipe 3, and a chute 5 inclined between the bottom end of the feeding pipe 3 and the top end of the discharge pipe 4, having a trapezoidal structure that is wider at the top and narrower at the bottom. A mounting block 6 is fixedly installed on the upper side of the bottom of the chute 5. Several blind holes 7 arranged in a rectangular array are opened on the front and rear sides of the mounting block 6. An inverted U-shaped bracket 8 is provided below the mounting block 6. A positioning box 9 with an open top is fixedly installed on the top of the horizontal part of the bracket 8. A first hydraulic cylinder 10 is fixedly mounted on the top of the horizontal part of the bracket 8 on the front and rear sides of the positioning box 9. The piston rod of the first hydraulic cylinder 10 faces the positioning box 9 and is fixedly connected to a limiting plate 11. Several limiting rods 12 are fixedly installed on the side of the limiting plate 11 near the positioning box 9. The limiting rods 12 can extend into the positioning box 9. The mounting block 6 is inserted into the positioning box 9. The limiting plate 11 abuts against the outer side of the positioning box 9 on the same side. The limiting rods 12 correspond one-to-one with the blind holes 7 on the same side and are inserted into it.

[0021] During coal conveying, the coal material enters through the feed pipe of the guide chute 2, and then, guided by the chute 5, converges towards the center of the belt conveyor 1. Finally, it is discharged through the discharge pipe 4 to the center of the belt conveyor 1, ensuring that the subsequent coal flow is effectively kept in the center of the conveyor belt of the belt conveyor 1, which is more conducive to improving the quality of coal conveying. After long-term use, if the guide chute 2 leaks due to impact wear or other reasons, it can be easily disassembled and replaced. Specifically, with the machine stopped, first run the two first hydraulic cylinders 10 to retract their piston rods, driving the limit plate 11 back until the limit rod 12 is completely pulled out of the positioning box 9, which releases the insertion limit of the mounting block 6. Then, move the entire guide chute 2 upward to remove the original guide chute 2. Next, take the new guide trough 2, align the mounting block 6 on it with the positioning box 9, and then operate the two first hydraulic cylinders 10 to extend their piston rods, causing the limiting plate 11 to press against the outside of the positioning box 9, so that the limiting rod 12 can be inserted into the corresponding blind hole 7, and the mounting block 6 is inserted and fixed in place, thus completing the fixed installation of the new guide trough 2. This allows for flexible and convenient assembly and disassembly of the guide trough 2, and facilitates easy replacement in case of leakage, making the overall device more convenient and practical. The belt conveyor 1 can be constructed using existing technology.

[0022] In this embodiment, the mounting block 6 is adapted to the mounting box 9 to ensure that the mounting block 6 is smoothly inserted and installed in place, so as to achieve the initial positioning and installation of the guide trough 2.

[0023] In this embodiment, the limiting rod 12 is adapted to the corresponding blind hole 7 to ensure that the limiting rod 12 is smoothly inserted into place, thereby achieving further limiting and fixing of the guide groove 2.

[0024] In this embodiment, a support plate 13 is fixedly connected between the two vertical parts of the support 8. A dust collector 14 and an exhaust fan 15 are installed on the support plate 13. A ring pipe 16 is sleeved on the outside of the feed pipe 4. Several dust collection hoods 17 are connected to the bottom of the ring pipe 16. The side of the ring pipe 16 near the support 8 is connected to the air inlet of the dust collector 14. The exhaust port of the dust collector 14 is connected to the air inlet of the exhaust fan 15. In actual coal operation, when the coal falls from the feed pipe 4 to the middle of the conveyor belt of the belt conveyor 1, there is a certain dust problem. At this time, the exhaust fan 15 can be run. Under the suction of the exhaust fan 15, the dust can be collected in the ring pipe 16 by the multiple dust collection hoods 17 around the feed pipe 4 and then sent to the dust collector 14 for dust removal. Finally, it is discharged through the exhaust fan 15, which can achieve effective dust removal and is more environmentally friendly and practical. Both the dust collector 14 and the exhaust fan 15 can be based on existing technologies. Specifically, the dust collector 14 can be a conventional bag filter or cyclone dust collector. The annular pipe 16 is located on the outer periphery of the feed pipe 4, and a certain distance is left between its inner ring and the outer side of the feed pipe 4, so as not to affect the disassembly and replacement operation of the entire feed chute 2, and to ensure the effective dust removal range.

[0025] In this embodiment, support legs 18 are vertically fixed on the left and right sides of the bottom of the two vertical parts of the support 8. Inverted U-shaped support plates 19 made of aluminum foam are fixedly sleeved on the support legs 18. In actual use, the support 8 and the entire guide trough 2 can be effectively supported and fixed by the cooperation of multiple sets of support legs 18 and support plates 19 without affecting the use of the guide trough 2. Moreover, aluminum foam is an existing material with excellent damping and shock absorption characteristics, which is more conducive to the stable operation of the guide trough 2.

[0026] In this embodiment, the outrigger 18 is a second hydraulic cylinder 20. The support plate 19 is fixedly sleeved on the outside of the cylinder body of the second hydraulic cylinder 20. The piston rod of the second hydraulic cylinder 20 faces downward and a caster 21 is installed on its bottom end. When the piston rod of the second hydraulic cylinder 20 is in the retracted state, the bottom end of the caster 21 is higher than the bottom end of the vertical part of the support plate 19. This allows the outrigger 18 to be configured as a second hydraulic cylinder 20 in actual use. When used for coal conveying, the cylinder body of the second hydraulic cylinder 20 acts as the outrigger 18, cooperating with the support... Plate 19 effectively supports and fixes the bracket 8 and the guide trough 2. When it is necessary to remove the entire bracket 8 and guide trough 2 from the corresponding belt conveyor 1, the second hydraulic cylinder 20 can be operated to extend its piston rod, driving the casters 21 to move down until the casters 21 are on the ground and lift the support plate 19. With the cooperation of the four sets of casters 21, the bracket 8 can move flexibly and easily, making it easier to remove from the belt conveyor 1, reducing the difficulty of operation, and making the overall use of the device more flexible and convenient. The first hydraulic cylinder 10, the second hydraulic cylinder 20, and the required supporting oil circuits and electrical control systems can all adopt existing technologies, and will not be described in detail here.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
