Description

Unloader and burnt powder production line Technical Field The utility model relates to the technical field of material conveying and dust prevention, in particular to a blanking device and a coke powder production line. Background In the sintering production link of steel smelting, coke powder is used as an important fuel, and the efficient and stable transportation plays a key role in the smooth proceeding of the sintering process. The large-inclination-angle belt conveyor has the advantages of large conveying angle, large conveying capacity, compact structure and the like, becomes common equipment for conveying after the coke powder is crushed in a sintering workshop, can effectively save the occupied area of the equipment, and meets the requirement of conveying large-scale materials. However, the four-roll crusher has a square blanking passage, the blanking area of the blanking passage is excessively large, the blanking amount is large and is not matched with the belt size, the blanking is easy to fall to an area outside the belt, and fine powder is easy to be thrown when the blanking falls to the surface of the belt. Because the large-inclination-angle belt conveyor is similar to the conveying mode of a chain bucket machine, the side plates on two sides of the hopper are difficult to seal by adopting the traditional blocking leather. In the coke powder transportation process, a large amount of fine ash can be sprayed out from two sides of the hopper, so that not only is the dust in the post site diffused, but also serious environmental pollution is caused, the whole production environment and the air quality of a workshop are affected, and the labor intensity of post personnel is greatly increased. At present, at least two people need to be arranged to clean the fine ash sprayed from two sides of the hopper after the crushing of each class is finished, which not only occupies a great deal of manpower and time cost, but also has the risk of endangering the health of staff due to long-time exposure in a high-dust environment. Therefore, there is a need to provide a discharging device and a coke powder production line to solve the above problems. Disclosure of utility model The utility model aims to provide a blanking device and a coke powder production line, which remarkably reduce the fine coke powder ash ejection amount, reduce the working time and labor intensity of post personnel for cleaning fine ash, improve the working environment of a sintering workshop, reduce dust pollution, improve the environmental protection and safety of workshop production and realize the clean and efficient transportation of coke powder on a large-inclination-angle belt conveyor on the premise of not influencing the normal operation of the large-inclination-angle belt conveyor and the coke powder transportation efficiency. To achieve the purpose, the utility model adopts the following technical scheme: The utility model provides a unloader, includes hopper, first guide, second guide and two at least cushioning members, the hopper set up in band conveyer's belt top, the unloading passageway has been seted up to the hopper lower extreme, two at least cushioning members follow the interval of belt width direction set up in the unloading passageway, adjacent form the feed opening between the cushioning members, first guide with the second guide follows the belt direction of operation relatively and the interval set up in the feed opening below, just first guide from the top down follows the belt direction of operation slope for with the material is directed the belt, the direction of inclination of second guide with the direction of inclination of first guide is opposite, is used for with the material direction of operation first guide. In some alternative embodiments, the projection of the lower end edge of the second guide in the vertical direction is located between the upper end edge and the lower end edge of the first guide. In some alternative embodiments, the horizontal projection of the lower end edge of the second guide in the direction of belt travel is between the upper and lower end edges of the first guide, and/or, The projection of the lower end edge of the second guide piece in the vertical direction is located at 1/3-2/3 of the distance between the upper end edge and the lower end edge of the first guide piece. In some alternative embodiments, the horizontal projection of the lower end edge of the second guide member in the belt running direction is 1/3 to 2/3 of the distance between the upper end edge and the lower end edge of the first guide member. In some optional embodiments, a blanking port is formed between the lower end of the second guide member and the first guide member, and the length L of the blanking port along the belt running direction ranges from 25cm to 35cm. In some alternative embodiments, the first guide member has an inclination angle α1 with respect to the horizontal direction in the rang
