Description

Technical Field

[0001] The utility model relates to the technical field of coke dry quenching technology, in particular to a coke powder cleaning device for a circulating fan ventilation network. Background Art

[0002] The so-called dry quenching process, relative to wet quenching, refers to a quenching process method that uses inert gas to cool down red coke.

[0003] After the coal is refined into coke in the carbonization chamber, it should be pushed out of the carbonization chamber in time. The temperature of the red coke when it is pushed out is about one thousand degrees. In order to avoid coke combustion and be suitable for transportation and storage, it cannot be sent directly to the blast furnace for ironmaking, and the temperature of the red coke must be lowered. Therefore, a circulating fan is needed. Although the existing circulating fan can provide power for the dry quenching cooling gas, a large amount of coke powder will be generated in the production process of dry quenching. The coke powder may adhere to the ventilation net at the suction of the fan due to the suction force of the circulating fan. The coke powder adheres to the suction of the fan for a long time, which may reduce the wind force of the circulating fan and cause the cooling efficiency of the red coke to decrease. The staff needs to perform cleaning operations frequently. Long-term contact with coke powder is harmful to human health, and manual cleaning operations are very time-consuming and labor-intensive, and inefficient. Therefore, designing a safe and efficient solution to clean the coke powder attached to the ventilation net is a problem that needs to be solved at present. Summary of the invention

One end of the threaded screw in the screw transmission pair is connected to the output shaft of the motor, and a bearing is sleeved on the outside of the other end of the threaded screw. A bearing seat rotatably connected to the bearing is provided at the corresponding bearing position of the first column.

[0011] Furthermore, the dust suction tube is a corrugated tube.

[0012] Furthermore, the end of the dust suction pipe is connected to an air collecting pipe corresponding to the length of the brush plate. The air collecting pipe is located below the brush plate and is fixedly connected to the brush plate. A plurality of dust suction holes are arranged in sequence on the air collecting pipe.

[0013] Furthermore, the dust suction device comprises a box body, an exhaust fan is arranged in the box body, and a filter is arranged at the connection between the box body and the dust suction pipe.

[0014] Furthermore, the circulation fan is arranged on a fixed seat, a receiving groove for receiving the circulation fan is arranged on the top of the fixed seat, and reinforcing plates for strengthening the center of gravity balance of the fixed seat are respectively arranged on both sides of the fixed seat.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1. The utility model drives the brush plate to move on the surface of the ventilation net through a traction device, and the brush on the brush plate sweeps away the dry quenching dust attached to the surface of the ventilation net. The dust suction hole cooperates with the brush to suck the swept dry quenching dust into the dust suction device, thereby improving the working efficiency of the circulating fan body and the safety of personnel.

[0018] 2. The utility model can facilitate the installation of the circulation fan body by providing a fixing seat, thus playing a role of installation and fixing.
