Description

Broken grinding machine
Technical field
The utility model relates to a kind of broken grinding machine, is applicable to building materials, chemical industry, controls gold, the fragmentation of the hard brittle material of power industry, is particularly useful for the Super-fine grinder of clinker is pulverized.
Background technology
In the grinding system of cement industry, the grinding system power consumption accounts for more than 70% of total power consumption, implements the outer precrushing of mill, reduces the mill feed material particle diameter, improves system's grinding output, reduces production costs significantly, obtains the common recognition of cement industry already.Grinding system is implemented the outer precrushing of mill, and thing must gone.But in the more than ten years, implement to have equipment operation fault rate height all the time in the clinker precrushing, operating cost is high, can not adapt to the drawback of the demand of modern enterprise.Released a collection of disintegrating apparatus of clinker preferably in China over the past two years, as the patent No. is the stitching crusher that the screening function is arranged of ZL00224822.0, the excellent broken grinding machine of interior sieve that the patent No. is 01214438.X, in actual use, all obtained effect preferably.But, these equipment the former to exist broken physique amount big, operational shock is serious, consumable accessory is changed difficulty, the defective of broken poor stability; And the latter exists investment high, and broken body is elongated, and operational shock is big, and broken poor stability, broken body are directly made defectives such as the random rod in back after levigate.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of running high-efficiency and economic, safe and reliable is provided, the broken efficiently grinding machine of convenient operating maintenance.
The purpose of this utility model is achieved like this:
Be the main shaft that broken grinding machine described in the utility model comprises spindle drum, driven by motor and decelerator, rotating cylinder; It is characterized in that: the two ends of rotating cylinder are connected with main shaft and the quill shaft that is positioned at hollow axle bed and bearing respectively; Feed hopper passes quill shaft and is communicated with rotating cylinder; On the circumference outside the rotating cylinder, has the collecting hood of band dust-exhausting port and discharging opening; Described rotating cylinder has the skin of band discharge port and access hole, is positioned at the ladder grate plate with band dumping pit and diffusion chamber on this skin inner periphery, has broken body in the cavity that the ladder grate plate is surrounded.
The utility model is owing to described structure has following advantage:
1, adopt broken body from falling the gravity broken material, break-up point is many, and no hard grind is wiped, broken output height.
2, adopt the broken body of point-like gravity, attended operation is convenient and swift, and crushing performance is stable, after broken body diameter mill is little, recyclablely uses for ball mill.
3, adopt the gravity broken material that falls certainly of broken body, eliminated the favorable loss of iron block access arrangement, equipment is safe and reliable to operation.
4, adopt the ladder grate plate, the discharging area is big, in time discharges the material of qualified particle diameter, has eliminated the fine powder cushion, has thoroughly solved fine powder to the moderate effect of broken body, has increased substantially the breaking capacity of broken body.
5, adopt the ladder grate plate of band diffusion chamber, discharging is unimpeded, putty not, and it is few to cross broken material, the unit-hour output height.
6, ladder grate plate, the discharging particle diameter is even, and the grating of grinding machine abrasive body is accurately convenient, grinding system output height.
7, ladder grate plate is with broken body hoisting power strong, and broken body impulsive force is big.
8, the low investment of the utility model can make short mill into the grinding process of Super-fine grinder, grinding system output height.
9, adopt roller bearings and contain the collecting hood collection material of dust-exhausting port, power consumption is low, and is dustproof, heat resistance is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a system flow chart;
Fig. 3 is a ladder grate plate view;
Fig. 4 is the A-A cutaway view of Fig. 3;
The specific embodiment
Referring to Fig. 1 and Fig. 2, bearing 13,11 is arranged in spindle drum 17 and the hollow axle bed 2, quill shaft 3 is arranged on the bearing 13, feed hopper 1 is arranged in the quill shaft, workshop section's conveying equipment before feed hopper is connected in, main shaft 10 is arranged on the bearing 11, and main shaft is connected with motor 18 via decelerator 12, and the two ends of rotating cylinder 4 and main shaft and quill shaft connect to form a rigidity body.Discharge port 5 and manhole 7 are arranged on the circumference of rotating cylinder 4, the ladder grate plate 8 that contains dumping pit 9 and diffusion chamber 24 is arranged on the whole inner periphery of rotating cylinder, broken body 14 is arranged in the ladder grate plate of rotating cylinder.The collecting hood 16 that contains discharging opening 15 and dust-exhausting port 6 is arranged on the excircle of rotating cylinder, and discharging opening is connected in output equipment 20, and dust-exhausting port 6 is connected in deduster.
In said apparatus, broken body 14 is ellipsoid, spheroid or short cylinder.
Referring to accompanying drawing 3,4: the section of ladder grate plate 8 is for imitative trapezoidal, and the dumping pit 9 on the ladder grate plate is a rectangle.The ladder grate plate is stepped by constituting on the inner periphery of rotating cylinder on the inner periphery that is bolted to rotating cylinder 8 by the screw on it; With the discharge port 5 on the dumping pit 9 corresponding rotating cylinder skins on the ladder grate plate 8 be that several circular ports are formed.
When using the utility model, as Fig. 1 and Fig. 2, motor footpath decelerator deceleration force amplifier rear drive main shaft, rotating cylinder, quill shaft are done gyration around the axis of two bearings, and when rotating cylinder was done gyration, broken body was under the effect of centrifugal inertial force, be attached on the ladder grate plate of rotating cylinder, turn round with rotating cylinder, taken to certain height by the ladder grate plate after, by the gravity effect of itself body, fallen by impelling, will smash by the material that feed arrangement is come in.Qualified particle diameter material after being crashed to pieces, pass dumping pit, diffusion chamber on the ladder grate plate, fall in the collecting hood via the discharge port on the rotating cylinder, discharge from the discharging opening of collecting hood, the material that discharging opening is discharged is transported in the ball mill 21 by grinding by promoting conveying equipment, and the off grade size material is still stayed broken and continued fragmentation in the grinding machine.Enter in the ball mill behind the material ball mill grinding by promoting conveying equipment 22 and deliver to ultra-fine powder concentrator 23 and carry out sorting, qualified products are transported to the hypomere operation, substandard product is sent ball mill grinding once more back to, and the air-flow that dust in the rotating cylinder and heat retinue feed arrangement are come in enters discharge after the purification in the deduster through the dust-exhausting port of collecting hood.
