Due to the structural relation, the hoist frame, in particular to the large hoist frame, has more residual materials, and if the hoist frame is not cleaned for a long time, the hoist frame is easy to mold, germinate and harden, so that the use of equipment is affected, and the environment is polluted. The conventional large-scale elevator frame is manually cleaned, so that not only is the labor wasted, but also the operation environment is usually bad, and the cleaning is not clean.

Disclosure of utility model

The technical problems to be solved by the utility model are as follows: in order to overcome the defect that residual materials in a lifting machine base are difficult to clean in the prior art, the utility model provides a clean material air conveying system for a bucket elevator.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a bucket elevator connects silo with clear material air feed system, includes fan, salon and frame, the frame connects the silo cover to locate the mouth department that gathers materials of lifting machine casing bottom, frame connects silo one end to communicate with salon feed inlet through first tuber pipe, the air inlet of fan communicates with the gas outlet of salon, the gas outlet of fan connects the silo to keep away from the one end intercommunication of first tuber pipe through the second tuber pipe with the frame, salon's discharge gate department is equipped with opens and close the valve, it locates the blanking mouth top of lifting machine to open and close the valve, it is connected with the unloading elephant trunk to open and close on the valve, the lower extreme of unloading elephant trunk extends to the blanking mouth department of lifting machine.

The fan is used as a power mechanism of a material cleaning air conveying system, so that the first air pipe is used for exhausting air, the second air pipe is used for exhausting air, and residual materials which fall on the bottom of the elevator shell and on the material receiving groove of the machine base are conveyed by wind power and enter the salon through the first air pipe; the material-containing air flow is rotated by the salon, the material is separated from the air flow by virtue of centrifugal force and is trapped on the inner wall surface, then the material falls into the ash bucket by virtue of the gravity effect, and the material automatically sinks to the salon discharge port; the air flow without material enters the fan through the air outlet of the saxophone. After the material cleaning air conveying system is started for a period of time, the opening and closing valve is opened, materials fall into a blanking port of the lifting machine through the blanking chute, and the lifting machine lifts and conveys the cleaned and collected materials again.

Further, in order to prevent dead angles exist in the machine base receiving groove, materials cannot be cleaned up, the cross section of the machine base receiving groove in the vertical direction is arc-shaped, and the inner diameter of the machine base receiving groove is the same as the inner diameters of the first air pipe and the second air pipe.

Further, the material collecting port is of a conical structure with a wide upper part and a narrow lower part.

Further, the opening and closing valve is a butterfly valve.

Further, the model of the salon is CLK diffusion salon.

The beneficial effects of the utility model are as follows: according to the material cleaning air conveying system for the bucket elevator, the machine base receiving groove, the first air pipe, the saxophone, the fan and the second air pipe are matched with each other to form a complete air conveying system, residual materials in the elevator base are cleaned, the self-cleaning function of the elevator base is achieved, and the material cleaning air conveying system has the advantages of being small in failure rate, environment-friendly in conveying, good in cleaning effect, low in cost and the like.
