Description

Technical fields:

[0001] This utility model relates to the field of coke conveying technology, and specifically to a coke conveyor. Background technology:

[0002] During coke transportation, a large amount of dust is generated at the discharge point, which not only pollutes the environment but may also affect the health of operators. Furthermore, the impact force of the falling coke easily causes it to break, reducing the proportion of large coke pieces and impacting product quality and economic benefits. Traditional dust prevention and cushioning measures are ineffective. Traditional cushioning devices are mostly rigid structures that cannot effectively absorb impact energy, leading to the easy breakage of large coke pieces. In addition, dust spillage not only pollutes the environment but also accelerates the failure of mechanical components. Utility Model Content:

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a coke conveyor mainly consists of a support frame, a conveyor 1, a discharge pipe 2, a negative pressure dust collection device 3, a high-pressure air curtain device 4, and a stepped buffer device 9. The support frame is used to support the entire conveyor system and ensure its stable operation. The conveyor 1 is fixed on the support frame, and one end of it is set at the lower end of the discharge pipe 2 to receive and transport the coke falling from the discharge pipe 2.

[0022] The negative pressure suction device 3 is fixed on the outer wall of the discharge pipe 2. Specifically, it includes a negative pressure suction pipe 5. The negative pressure suction pipe 5 is made of stainless steel, which has good corrosion resistance and strength. A suction head is fixed at its bottom. The suction head is shaped like a flared mouth, which can increase the suction area and improve the suction efficiency. The top of the negative pressure suction pipe 5 is fixedly connected to an external negative pressure vacuum cleaner through a conduit. The conduit is made of rubber hose, which has a certain degree of flexibility and is easy to install and maintain. A fixing bracket is welded on the outer wall of the discharge pipe 2 to fix the negative pressure suction pipe 5 on the discharge pipe 2 and ensure its stable position.

[0023] The high-pressure air curtain device 4 is set on the outside of the negative pressure dust collection device 3 and is fixedly connected to the conveyor 1 through the bracket. The high-pressure air curtain device 4 includes an air blowing block 6 arranged in a ring outside the negative pressure dust collection pipe 5. The air blowing block 6 is made of aluminum alloy, which is lightweight and high-strength. The air blowing block 6 has an open cavity, and the bottom of the open cavity is connected to an air outlet gap. The width of the air outlet gap is 2mm, which can ensure that the blown air has a certain speed and intensity. The air blowing block 6 is sealed with a cover plate 7. The cover plate 7 and the open cavity form an air blowing channel. The cover plate 7 is fixed to the air blowing block 6 with bolts to ensure a tight connection and prevent air leakage. Four connecting pipes 8 are fixedly connected to the cover plate 7. The connecting pipes 8 are symmetrically arranged on the cover plate 7 and are connected to the open cavity. The connecting pipes 8 are connected to an external high-pressure blower through the pipes. The high-pressure airflow generated by the high-pressure blower enters the air blowing channel through the connecting pipes 8 and is blown out from the air outlet gap to form an air curtain.

[0024] The stepped buffer device 9 is fixed on one side of the conveyor 1 and set at the lower end of the output end of the discharge pipe 2. The stepped buffer device 9 includes multiple idler roller groups arranged in a stepped manner. The inclination angle of each idler roller group is 20° and the spacing between adjacent idler roller groups is 400mm. Each idler roller group includes an idler roller 10 set in the middle and idler rollers 10 symmetrically located on both sides of the middle idler roller 10. The idler roller 10 is made of steel pipe and is covered with a rubber covering layer 11 with a thickness of 15mm. The rubber covering layer 11 is made of wear-resistant rubber material and has good elasticity and wear resistance.

[0025] The rotating shafts on both sides of the idler roller 10 are rotatably connected to the buffer assembly via bearings. The buffer assembly is fixed on the fixed frame. The buffer assembly includes a sliding block 12 and a limiting block 13. The sliding block 12 is embedded in the limiting groove and is slidably connected to the limiting groove. The limiting groove is fixed on the limiting block 13. A damping spring 14 is fixedly connected to the bottom of the limiting groove. The top of the damping spring 14 is fixedly connected to the sliding block 12. Both the sliding block 12 and the limiting block 13 are made of steel and have sufficient strength. The damping spring 14 is a helical spring with a suitable elastic coefficient, which can effectively absorb the impact force when the coke falls.

[0026] Actual working process:

[0027] When coke falls from the discharge pipe 2, a large amount of dust is generated at the outlet of the discharge pipe 2. At this time, the high-pressure fan of the high-pressure air curtain device 4 starts, and the high-pressure airflow enters the blowing channel through the connecting pipe 8 and is blown out from the air outlet gap, forming a ring-shaped high-pressure air curtain. This air curtain forms a barrier around the outlet of the discharge pipe 2, preventing the dust from spreading outward. At the same time, the negative pressure dust collector 3 starts, sucking in the dust blocked by the air curtain through the negative pressure dust collection pipe 5 and the dust collection head, and transporting it to the dust removal equipment for treatment through the duct. The synergistic effect of the high-pressure air curtain and the negative pressure dust collection device can effectively control the spread of dust and reduce the dust concentration in the working area.

[0028] After the coke falls from the feed pipe 2, it first impacts the idler rollers of the stepped buffer device 9. Since the idler rollers are set in a stepped manner and have a certain inclination angle, the impact force of the coke will gradually disperse along the direction of the steps when it rolls on the idler rollers. At the same time, the rubber covering layer 11 on the outside of the idler roller 10 has good elasticity and can absorb part of the impact force. In addition, the idler roller 10 is connected to the fixed frame through the buffer assembly. When the coke impacts the idler roller 10, the idler roller 10 drives the sliding block 12 to slide in the limiting groove, compressing the damping spring 14. The elastic deformation of the damping spring 14 can convert the impact force into elastic potential energy and further absorb energy. Through the combined action of the stepped idler rollers, the rubber covering layer and the buffer assembly, the impact force when the coke falls can be significantly reduced, and the breakage rate of the coke can be reduced.

[0029] Coke falls from the discharge pipe 2, passes through the dust control area of ​​the high-pressure air curtain device 4 and the negative pressure dust collection device 3, and then impacts the idler roller group of the stepped buffer device 9. After being buffered, it falls onto the conveyor 1 and is transported to the designated position by the conveyor 1. Throughout the process, the high-pressure air curtain device and the negative pressure dust collection device work continuously to control dust pollution, and the stepped buffer device buffers the coke to reduce breakage.

[0030] 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.
