Description

Technical Field

[0001] The utility model relates to the technical field of dust and ash treatment, in particular to a treatment device for coking desulfurization and dust removal ash. Background Technique

[0002] In the traditional iron and steel smelting process, coke is used as the main raw material for blast furnaces, and coking desulfurization and dust removal ash refers to the solid waste generated after being treated by desulfurization and dust removal equipment during the coking process. It contains a large amount of coke powder and desulfurizer. Through reasonable treatment and utilization, it can effectively reduce the impact of coking desulfurization and dust removal ash on the environment and promote the recycling of resources. Therefore, a treatment device is needed to process it.

[0003] The inventor found the following problems in the prior art during the implementation of this application:

[0004] In the prior art, the particle size of coking desulfurization and dust removal ash is small, and a large amount of dust will be generated during dry powder transportation after collection, polluting the environment. After humidification, due to the desulfurizer contained in the dust sticking and caking, it will cause the transportation device to be blocked, and during the treatment process of coking desulfurization and dust removal ash, it is usually necessary to manually intercept part of the raw coal from the conveyor belt and mix it with the ash, which is rather laborious.

[0005] Therefore, those skilled in the art provided a treatment device for coking desulfurization and dust removal ash to solve the problems raised in the above background technique. Summary of the Invention

Near one side of the upper end of the outer wall of the outer shell, a discharge pipe is embedded. At the lower end of the opposite side of the outer shell and the stirring barrel, a connection box is embedded.

[0010] Further, the rotating shaft is rotatably provided at the centers of both sides of the inner wall of the adjustment box.

The transmission shaft is fixedly connected to the output end of the third motor. At both ends near the front and rear of the upper end of the inner wall of the outer shell, three atomizing nozzles are fixedly provided.

[0013] Further, at the center of the upper end face of the outer wall of the outer shell, a second motor is fixedly provided. The spiral conveyor is fixedly connected to the output end of the second motor.

[0014] Further, at the centers of the bottom end faces of the inner walls of the two guide rails, threaded rods are respectively rotatably provided. The two threaded rods respectively threadedly penetrate through the two sliders. The two threaded rods are respectively fixedly connected to the two horizontal bevel gears.

[0015] Further, one end of the second conveyor belt is located below the discharge pipe and the other end is located above the first conveyor belt. One end of the third conveyor belt is located above the stirring barrel.

[0016] The utility model has the following beneficial effects:

[0017] 1. A treatment device for coking desulfurization and dust removal ash proposed by the present utility model conveys raw coal to the inside of a stirring barrel through a No. 3 conveyor belt, then starts a No. 3 motor to drive a transmission shaft and a threaded sleeve to rotate, and drives a plurality of stirring rods to rotate and stir, so that the raw coal adheres and mixes with the coking desulfurization and dust removal ash conveyed into the stirring barrel. The mixed raw coal falls into the inside of a housing along a connecting box, and is sent out from a discharge pipeline through a screw conveyor rod and sent to the upper end surface of a No. 1 conveyor belt again through a No. 2 conveyor belt for use as raw materials. The wet raw coal adsorbs the coking desulfurization and dust removal ash, and prevents the coking desulfurization and dust removal ash from directly mixing with water and causing adhesion and blockage of the device, and can be reused.

[0018] 2. For a treatment device for coking desulfurization and dust removal ash proposed by the present utility model, start a No. 1 motor on one side of an adjustment box to drive a rotating shaft to rotate. The rotating shaft drives two longitudinal bevel gears to rotate, and at the same time makes the two longitudinal bevel gears drive two transverse bevel gears to rotate synchronously, and drives two threaded rods to rotate respectively through the two transverse bevel gears. Thus, sliders respectively threadedly sleeved on the outer walls of the two threaded rods move vertically along the two guide rails, thereby driving a mounting rod and a deflector to move vertically, so that while not affecting the normal conveyance of raw coal by the No. 1 conveyor belt, the deflector intercepts part of the raw coal instead of manual labor, facilitating its mixing with the coking desulfurization and dust removal ash, and making the interception process more labor-saving.
