Abstract

The invention discloses a combined type classifier. The classifier comprises an outer cylinder, an inner cylinder arranged in the outer cylinder, and a classifying motor arranged on the upper end of the outer cylinder by a bracket, wherein the lower end of an output shaft of the classifying motor is fixedly connected with a rotating shaft which extends to the internal of the outer cylinder; a classifying impeller which is above the inner cavity is arranged on the lower end of the rotating shaft; the outer shell of a bulk tray is provided with a feeding inlet; the lower end of the outer cylinder is provided with a discharging outlet; the lower end of the inner cylinder is a conical discharging hopper; the side wall of the discharging hopper is provided with a screen mesh; and the discharging hopper is connected with an air classifier. The classifier of the invention scatters and classifies the materials for many times which are pressed by a roll squeezer, separates the materials which are not pressed or not completely pressed by combining the air classification with screening and then sends the separated materials back to the roller squeezer. The classifying efficiency is high.

Description

Combined type classifier
Technical field
The present invention relates to scattering and grading equipment, specifically is a kind of combined type classifier.
Background technology
At present, be accompanied by the high speed development of Chinese national economy in recent years, China's cement production capacity has reached 1,000,000,000 tons.New production line all is the large-scale production line in 700,000 tons of annual outputs and above scale thereof, ton cement power consumption is about 90~100kWh, and the power consumption of cement grinding workshop section accounts for and produces 60~70% of cement power consumption, only cement grinding this, a year power consumption just reaches about 60,000,000,000 degree.And roll squeezer can make system's volume increase 50%~200% in the successful Application of cement grinding system, and economize on electricity 20%~40% has been saved the energy, reduced the manufacture of cement electricity consumption, thereby realizes sustainable development.Roll squeezer applying high voltage bed of material pulverization principle, adopt single material to pulverize the working method of group feature, brittle material reduces surmising rapidly of material through high-pressure extrusion (pressure of crush zone is about 150MPa), fine powder content less than 0.08mm reaches 20~30%, material less than 2mm reaches more than 70%, and has a large amount of micro-cracks in all materials through pushing, and has improved the grindability of material, make material in next operation during grinding, required energy consumption reduces significantly.According to our the acquired actual data of using, adopt the grinding system of roll squeezer can increase production 50~200% than former traditional grinding system, the per unit area yield power consumption can reduce by 20~40%, the noise of equipment work also reduces to some extent simultaneously, improve the worker laboring environment, fully demonstrated remarkable economic benefit and social benefit.
Summary of the invention
The purpose of this invention is to provide a kind of combined type classifier, the material that pushed through roll squeezer is broken up and multiple fractionation, though the combination by selection by winnowing and screening will be come out without extruding and through the feed separation of pushing but not being adequately compressed, send roll squeezer back to and push again, efficiency of separation height.
Technical scheme of the present invention is as follows:
Combined type classifier, include outer cylinder body, be set with inner barrel in the outer cylinder body, the upper end of outer cylinder body is equipped with split-pole motor by support, the output shaft lower end of split-pole motor is fixedly connected with the rotating shaft that extend into outer cylinder body inside, the lower end of rotating shaft is equipped with the classifying turbine that is positioned at the inner barrel top, rotating shaft is set with hollow shaft outward, hollow shaft is by breaing up motor-driven, the lower end of hollow shaft is equipped with the bulk cargo dish, the shell body of the top of bulk cargo dish has charging aperture, and the lower end of outer cylinder body has discharging opening, it is characterized in that: described inner barrel lower end is conical hopper, be furnished with mesh on the sidewall of hopper, hopper is connected air classifier, and described air classifier comprises the air intake passage that crosses, the air-out passage, tapping channel, blanking channel, its intersection is fixed with the bulk cargo plate of interlaced arrangement.
Described air classifier is built in the outer cylinder body, and air intake passage, tapping channel, blanking channel all pass the sidewall of outer cylinder body; Air classifier or be placed on outside the outer cylinder body.
Described bulk cargo plate is through Wear-resistant Treatment, and arrangement is herringbone each other.
Beneficial effect of the present invention is as follows:
1, the present invention is to having been carried out multi-level sorting by the material of sorting, efficiency of separation height; And adopt the principle of screening back selection by winnowing earlier, reached the purpose of energy efficient;
2, all do Wear-resistant Treatment or adopt high-abrasive material to make with the position that material fully contacts, prolonged service life of equipment;
3, adopt the mode of piecemeal making for the consumable accessory of need periodic replacement, reduced the weight of consumable accessory, be easy to mounting or dismounting.
