Disclosure of Invention

The utility model discloses an overcome not enough that prior art exists, provide a sealing device who prevents that ball mill from leaking the material.

The utility model discloses a realize through following technical scheme: the utility model discloses a sealing device for preventing material leakage of a ball mill, which comprises a cylinder body part, wherein the front side of the cylinder body part is fixedly connected with a feeding part, a main bearing part, a drum-shaped feeder and a feed hopper in sequence, and the rear side of the cylinder body part is fixedly provided with a discharging part, a transmission part, a speed reducer, a shaft coupling and a motor in sequence; a sealing device for preventing the ball mill from leaking materials is arranged at the joint of the feed hopper and the drum-shaped feeder, and comprises a sealing cavity, a feeding pipe, a closed material receiving facility, an exhaust pipe and a dust collecting system; the device comprises a feed hopper, a drum-shaped feeder, a sealed cavity, an exhaust pipe, a dust collecting system, a discharging pipe and a sealed material receiving facility, wherein the sealed cavity is arranged at the joint of the feed hopper and the drum-shaped feeder, the upper part of the sealed cavity is connected with the exhaust pipe, the exhaust pipe is communicated with the dust collecting system, fine dust flying in the ball mill is sucked away from the upper part of the sealed cavity by the dust collecting system through the exhaust pipe, the discharging pipe is arranged at the lower part of the sealed cavity and is connected with the sealed material receiving facility, and large-particle dust generated in the ball mill naturally falls down and falls into the sealed material receiving facility to be sealed and recovered.

A lower funnel with a big upper part and a small lower part in the shape of an opening is arranged between the blanking pipe and the bottom of the sealing cavity.

The utility model has the advantages that: the utility model discloses prevent that sealing device that ball mill leaked material adds in feed inlet and ball mill junction and establishes a sealed chamber, adds a pipeline and dust collecting system connection on the upper portion in sealed chamber, and the tiny dust that flies upward siphons away from upper portion, sets up down the funnel in the lower part in sealed chamber, and the large granule dust falls down naturally, carries out sealed recovery. Thus, the problems of material leakage and dust flying are thoroughly solved.

The utility model discloses prevent that sealing device of ball mill hourglass material still has following advantage: since the utility model provides a sealing device uses years, and the effect is very obvious, and the hourglass material and the dust problem of flying upward of calcine feed opening and ball mill junction are thoroughly solved. The utility model provides a sealing device has improved workman's operational environment greatly, and the environmental pollution problem is solved. Because no dust flies, the loss of valuable metals can not be caused, thereby improving the recovery rate. Due to the use of the sealing device, no dust flies, the influence on the lubrication of on-site electrical equipment and bearings is small, the service life is prolonged, and the failure rate of the equipment is reduced. The investment of the device is very small, but the device solves a big problem in practical application.
