[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. 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 without creative work are within the scope of protection of the present invention.

[0030] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0031] The embodiment of the utility model provides a residual coal recovery device, which is used on a coke oven pushing car 1. The coke oven pushing car 1 includes a car body and a hopper 3 arranged on the car body.

[0032] The coke pusher 1 typically runs on tracks near the coke oven. During coke oven operation, its primary functions are opening and closing the oven door, pushing red coke out of the coke oven carbonization chamber, cleaning the oven door and oven frame, and handling the head and tail coke. The coke pusher 1 is equipped with a hopper 3 for collecting residual coke, coke dust, and tar that falls during door removal, coke pushing, oven frame cleaning, and door cleaning.

[0033] like Figure 1 As shown, the residual coal recovery device of this embodiment includes a first conveyor 4, a second conveyor 5 and a lifting mechanism 6 respectively arranged on the vehicle body.

[0034] The first conveyor 4 is located below the hopper 3 to convey the coal in the hopper 3. In daily production operation, the hopper 3 can be used to store coal cakes and the like that are about to fall, and fall onto the conveyor through its outlet end.

[0035] The second conveyor 5 is rotatably mounted on the vehicle body to receive and transport the coal from the first conveyor 4. The second conveyor 5 has a storage state in which it is vertically arranged and a working state in which it is inclined.

[0036] When the coke pushing car 1 is used, the second conveyor 5 can be switched to a working state so that the end of the second conveyor 5 is rotated to above the coal charging car 2 to convey the coal to the coal charging car 2 for transportation.

[0037] When the coke pushing car 1 is not in use, the second conveyor 5 can be switched to the storage state, so as not to affect the travel, coke pushing and maintenance of the coke pushing car 1.

[0038] The lifting mechanism 6 of this embodiment is connected to the second conveyor 5 to drive the second conveyor 5 to rotate relative to the vehicle body so as to switch between the storage state and the working state.

[0039] The residual coal recovery device of this embodiment can directly convey the coal cakes collected in the hopper 3 of the coke pushing car 1 to the coal charging car 2 for direct use by arranging the first conveyor 4 and the second conveyor 5 on the coke pushing car 1, thereby avoiding the need for other vehicles to transport the coal cakes. The device has a high degree of automation, reduces resource waste, and improves labor efficiency. At the same time, the second conveyor 5 is in a vertical storage state, which does not affect the normal travel, pushing, and maintenance of the coke pushing car 1.

[0040] In some embodiments, the coal loading car 2 is equipped with a coal storage bin 8. The bottom outlet of the coal storage bin 8 can discharge coal into the excess coal recovery system of the coal loading car 2, forming a continuous transfer. When the second conveyor 5 rotates to the working state, its end is located above the coal storage bin 8, and the coal conveyed by the second conveyor 5 can enter the coal loading car 2 through the coal storage bin 8.

[0041] In some embodiments, the first conveyor 4 and the second conveyor 5 are chain-type conveyors. Preferably, the chains of the two conveyors are non-slip and wear-resistant metal chain plates with raised dots, and the thickness of the chain plates is not less than 3 mm. The non-slip and wear-resistant metal chain plates with raised dots can effectively reduce coal slippage, reduce corrosion, and increase the service life of the conveyors.

[0042] In some embodiments, each chain plate of the second conveyor 5 is provided with a scraper (not shown in the figure), and the length direction of the scraper is perpendicular to the conveying direction of the second conveyor 5. Each chain plate is provided with a scraper, which can ensure that the chain plate carries the coal powder up a large angle to achieve the purpose of conveying.

[0043] Preferably, the transverse width of the scraper of this embodiment is smaller than the transverse width of the chain plate, thereby avoiding friction between the scraper and the body shell of the conveyor.

[0044] In this embodiment, a sealing cover can be used to seal the upper portion of the chain plate of the first conveyor 4 and the outlet of the hopper 3 on the coke pushing car 1, so as to avoid dust generation when the coal is unloaded.

[0045] In some embodiments, the first end of the second conveyor 5 is hinged to the vehicle body. A lifting mechanism 6 fixed to the vehicle body is a chain hoist located above the first end of the second conveyor 5. A chain 7 in the lifting mechanism 6 is connected to the second end of the second conveyor 5.

[0046] The chain hoist generally includes a motor, a drum and a chain 7 wound on the drum. The free end of the chain 7 is connected to the second end of the second conveyor 5. Its specific working principle belongs to the existing technology and will not be described in detail.

[0047] The retraction and extension of the second conveyor 5 can be controlled by controlling the forward and reverse rotation of the reel, thereby reducing or eliminating the impact on the coke pushing car 1 in the working state, and not affecting the travel, coke pushing and maintenance of the coke pushing car 1.

[0048] like Figure 2 As shown, in some embodiments, the residual coal recovery device further includes a discharge hopper 54 fixed to the second end of the second conveyor 5, and the discharge hopper 54 is used to receive the coal on the second conveyor 5 and guide the falling of the coal.

[0049] When the second conveyor 5 rotates to the working state, the discharge hopper 54 at the end thereof overlaps with the coal storage bin 8 , thereby transporting the coal on the second conveyor 5 to the coal loading vehicle 2 .

[0050] Preferably, the discharge hopper 54 of this embodiment is provided with a sight glass, through which the discharge of the coal can be observed.

[0051] Continue as Figure 2 As shown, in some embodiments, the second conveyor 5 includes a first horizontal section 51 , a middle section 52 and a second horizontal section 53 along its conveying direction.

[0052] The first horizontal section 51 forms a first end of the second conveyor 5 , and the second horizontal section 53 forms a second end of the second conveyor 5 .

[0053] The first conveyor 4 of this embodiment is arranged horizontally and is fixed to the coke pushing car 1 through a conveyor bracket 10 .

[0054] The first horizontal section 51 of the second conveyor 5 is located below the first conveyor 4. In this way, the pulverized coal conveyed by the first conveyor 4 falls on the second conveyor 5 by gravity at the end of the first conveyor 4 and is then conveyed by the second conveyor 5.

[0055] The lengthwise direction of the middle section 52 of the second conveyor 5 forms equal obtuse angles with the lengthwise directions of the first horizontal section 51 and the second horizontal section 53. When the second conveyor 5 is rotated into operation, the middle section 52 is tilted. The first horizontal section 51 receives the coal transported by the first conveyor 4, while the middle section 52 transports the coal from the first horizontal section 51 to the second horizontal section 53. The second horizontal section 53 then delivers the coal transported by the second conveyor 5 to the coal loading vehicle 2 via the discharge hopper 54.

[0056] The first conveyor 4 and the second conveyor 5 of this embodiment are driven by motors, each with a power of no less than 2 kW. The motor on the second conveyor 5 rotates with the second conveyor 5 .

[0057] The second conveyor 5 is located on one side along the moving direction of the coke pushing car 1. In some embodiments, a maintenance platform 9 is provided on the car body. The first end of the second conveyor 5 is hinged on the maintenance platform 9. The second conveyor 5 can rotate relative to the maintenance platform 9. The lifting mechanism 6 is located above the maintenance platform 9. The operator can stand on the maintenance platform 9 to inspect the lifting mechanism 6.

[0058] Preferably, an avoidance groove is provided on the maintenance platform 9 of this embodiment. When the second conveyor 5 rotates to the storage state, part of it can move into the avoidance groove, thereby not affecting the rotation of the second conveyor 5.

[0059] In some embodiments, the residual coal recovery device further includes sealing covers (not shown in the figure) buckled on the first conveyor 4 and the second conveyor 5 respectively, and the sealing covers can avoid dust problems during the transportation of coal.

[0060] Preferably, the sealing cover buckled on the second conveyor 5 and the sealing cover buckled on the first conveyor 4 are staggered and fitted together, so as to avoid affecting the rotation of the second conveyor 5 .

[0061] The residual coal recovery device of this embodiment also includes a control system for controlling the operation of the two conveyors and the lifting mechanism 6. The control system is arranged in the electrical room of the coke pushing car 1 for convenient control. The relevant control switches and corresponding limit switches are added to the electrical control cabinet in the electrical room.

[0062] This embodiment also provides a coke oven pushing car, which includes a residual coal recovery device as described in any of the above embodiments.

[0063] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Furthermore, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
