Abstract

The utility model provides a high-efficiency energy-saving crusher with double rotors, which can be applied to construction material industry, mining industry, metallurgy industry and chemical industry. The hammers of the crusher adopt wedge structure, bidirectional inclined planes of feeding, and labyrinth seal. The utility model has the characteristics of high efficiency, saving energy, high hammer durability, homogeneously fine crushed material, good bearing seal property, etc.

Description

Energy-efficient birotor pulverizer

The utility model belongs to a kind of size reduction machinery in building materials, mine, metallurgy, the chemical industry.

Its major defect of various hammer mills that uses is at present, and the species charging is inhomogeneous, the tup serious wear, and efficient is low, energy consumption is high, and raw meal particle size is crossed thick and inhomogeneous, and dust easily enters in the lower rotor part bearing.

Goal of the invention of the present utility model is based on the deficiency of above-mentioned disintegrating machine, provides a kind of rational in infrastructure, and efficient height, material charging are evenly, tup durability height, material pulverize efficient, the energy-conservation birotor pulverizer tiny, that the bearing seal performance is good.

The utility model is provided with two chargings in order to achieve the above object, and tup adopts wedge structure.The buildup dish with state the palace black box, all adopt ramp structure.

To closing accompanying drawing utility model is described further below.

Fig. 1 is an overall construction drawing of the present utility model

Fig. 2 is a tup front view of the present utility model

Fig. 3 is the utility model tup profile

Fig. 4 is the utility model labyrinth inclined plane sealing structure figure

By shown in Figure 1, the utility model is formed by being installed in motor 2 on the support, driving pulley 1, passive belt wheel 11, press strip 3, cylindrical shell 4, counterpunch board 5, rotor 6, novel tup 7, buildup dish 8, main shaft 9, hopper 10, feed hopper 12 etc.

During work, motor 2 drives main shaft 9 rotations by driving pulley, belt and passive belt wheel; All parts on the main shaft rotate with main shaft simultaneously.After spindle speed reached at full speed, material was through feed hopper 12 two-way entering in the pulverizing chamber.The wood that material is at first fallen rotation at a high speed gets rid of on the dish, and quilt is got rid of, and dish is dished out and counterpunch board collides; Because the effect of reaction force is rebounded by counterpunch board on the wedge shape tup that rotates at a high speed.After being subjected to the tup strike, clash into counterpunch board once more.Through after the circulation repeatedly of said process, material is fallen to form on the buildup plate 8 and is piled up like this.Along with the effect that increases and rotate tup at a high speed of material, material produces mobile and forms certain abrasive power.And the percussion of the material under being strikeed back, hitting, material is further pulverized.Thinner material is slipped to next stage and gets rid of on the dish from stockpile; Thicker material is because the effect of inertia force is thrown on the counterpunch board once more, and then being rebounded by counterpunch board is subjected to being thrown to counterpunch board once more after tup hits on the tup of rotation at a high speed.Through after circulating repeatedly, material is fallen to form on lower floor's buildup dish and is piled up like this.Milling, the mill of the tup of the material in the accumulation through rotating are at a high speed examined and are pulverized, and discharge from hopper at last.

This machine compared with prior art has the following advantages. One, because charging is adopted two-way Charging, efficient improves about 20% than like product. Two, because brittle material is main Extruding and bump and cracked. So tup adopts wedge structure, can be at littler bump Make material cracked in the situation of power. And can reduce the wearing and tearing of main body tup. Three, because Buildup adopts the inclined-plane blanking and makes raw meal particle size consistent. Four, the labyrinth seal ramp structure makes Discharging is smooth, and dust is difficult for entering in the bearing.

Claims

A kind of energy-efficient birotor pulverizer is characterized in that: feed hopper is 2, and tup is a wedge shape, is an inclined-plane above the buildup dish, and an inclined-plane is arranged on the labyrinth seal assemblies.
