Vertical shaft type superfine crusher

Abstract

The invention relates to a crusher, and in particular relates to a vertical shaft type superfine crusher which comprises a motor, a barrel, a lower bearing seat, an upper bearing seat, a vertical shaft, a hammer plate, a hammer head and a scraping device, wherein the upper bearing seat and the lower bearing seat are respectively provided with a water channel; the scraping device is arranged in the barrel and is connected with the hammer plate; and a protection plate is connected with the hammer plate by a wedge iron type connecting piece. Compared with the prior art, the vertical shaft type superfine crusher is provided with two water channels respectively on the upper bearing seat and the lower bearing seat, so that the material with the temperature below 400 DEG C can be crushed for a long time; the scraping device is arranged in the barrel, so that the sticky wet material bonded on a lining plate of the barrel can be separated, and blockage can be prevented; and the protection plate is connected with the hammer plate by the wedge iron type connecting piece, so that the hammer head is convenient to replace.

Description

technical field [0001] The invention relates to a crusher, in particular to a vertical shaft ultrafine crusher. Background technique [0002] At present, the structure of vertical shaft crushers used in various industries is arranged in a distributed manner between the main engine and the motor. If the equipment structure is unreasonable, it is inconvenient for users to install it: when the moisture content of the material in the crusher is greater than 6%, the material is pasted on the lining. On the plate, the incoming material is blocked, making the equipment unable to operate: the sealing device of the upper and lower bearings in the crushing chamber is sealed with felt in the labyrinth bearing gland according to the general technical specifications. This kind of seal has poor dustproof performance on this type of equipment, is not easy to maintain, and is very difficult to replace. There is no water cooling in the bearing part, and high-temperature materials cannot be ...

AI Technical Summary

Problems solved by technology

[0002]The structures of the vertical shaft crushers currently used in various industries are distributed and arranged by the main engine and the motor. When the water content of the material is more than 6%, the material is pasted on the liner, and the incoming material is blocked, making the equipment unable to operate: the sealing device of the upper and lower bearings in the crushing chamber is a labyrinth bearing gland according to the general technical specifications. Felt seal inside

This kind of seal has poor dustproof performance on this type of equipment, is not easy to maintain, and is very difficult to replace.

There is no water cooling in the bearing part, and high-temperature materials cannot be crushed. It takes a long time to replace the hammer head, and the labor intensity is high, which affects the popularization and use of the equipment.
