Description

Technical Field

[0001] The utility model relates to a graphite purging device for a carbonization chamber, belonging to the technical field of pusher cars. Background Technique

[0002] The graphite purging device is an important component in the pusher of coke oven machinery. This device is connected to the pusher rod and driven by a pusher motor and a pusher reducer to reciprocate in the carbonization chamber following the pusher rod. Due to long-term use, a large amount of graphite will deposit at the top of the carbonization chamber and the root of the riser pipe, and it is necessary to regularly clean the deposited graphite using compressed air.

[0003] At present, the existing connection method of the graphite purging device has the following disadvantages: the tightening and winding of the graphite purging hose are completed by pulling with a counterweight. This method is extremely easy to damage the air hose and cause the failure of graphite purging. The counterweight will swing randomly when running with the large car, posing a safety hazard.

An annular air distribution pipe is installed at the top of the blowing pipe. A plurality of blowing ports are arranged on the annular air distribution pipe. The bottom of the blowing pipe is connected with an air delivery pipe. The air delivery pipe is arranged along the length direction of the pusher rod. An air delivery pipe winding device is installed on the rear end bracket of the pusher rod. The air delivery pipe is a stainless steel corrugated hose. The air delivery pipe is wound on the air delivery pipe winding device, and the end of the air delivery pipe is connected with a compressed air supply pipe.

[0006] Preferably, the air delivery pipe winding device includes a servo motor, a hollow reel and blocking frames installed at both ends of the hollow reel. The servo motor is fixed on the rear end bracket of the pusher rod. The hollow reel is installed on the output shaft of the servo motor. Blocking frames are respectively installed at both ends of the hollow reel. Through holes are arranged on the hollow reel. The air delivery pipe extends into the hollow reel through the through holes. A rotary joint is installed at one end inside the hollow reel. The air delivery pipe and the compressed air supply pipe are respectively connected to the rotary joint. The servo motor is synchronously controlled with the pusher rod.

[0007] Preferably, a guide wheel and a pressure roller are further installed on the rear end bracket of the pusher rod.

[0008] Compared with the prior art, the utility model has the following technical effects: the gas transmission pipe of the utility model is driven to wind up and unwind by a servo motor, and the servo motor forms a closed-loop control with the coke pushing process, and the winding and unwinding of the gas transmission are completed along with the movement of the coke pushing rod. This design can more accurately realize the purging function, improve the service life of the equipment, and eliminate potential safety hazards; and the design structure is simple, and the operation and maintenance are convenient.
