Detailed description of the invention

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail:

It is embodied as such as Fig. 1, shown in Fig. 2, this utility model is a kind of double-geared roller crusher, including casing 1, motor 2 and cutter tooth roller 3, casing is provided with charging aperture 4 and discharging opening 5, charging aperture 4 is arranged on the top of cutter tooth roller 3, discharging opening 5 is arranged on the lower section of cutter tooth roller 3, cutter tooth roller 3 is connected with motor 2 power, cutter tooth roller 3 is provided with two groups, the axis of two groups of cutter tooth rollers 3 is arranged in the same direction, two components are high speed cutter tooth roller and low speed cutter tooth roller, high speed cutter tooth roller side is connected with decelerator, the speed of low speed cutter tooth roller is reduced by decelerator, the teeth of low speed cutter tooth roller are just contrary with the teeth of high speed cutter tooth roller, play the effect of solid material and feeding, described cutter tooth roller 3 includes roll shaft 6, crushing cutter 7 and shim 8, crushing cutter 7 and shim 8 are all disc-shaped structure, crushing cutter 7 is provided with teeth 9, crushing cutter 7 and shim 8 on same roll shaft 6 are crisscross arranged, crushing cutter 7 on two groups of cutter tooth rollers 3 forms staggered engaging structure, teeth 9 on the cutter tooth roller 3 of two groups, engagement place are towards on the contrary, and the rotation direction of two groups of cutter tooth roller 3 engagement places is straight down。This utility model is operationally, two intermeshing sides of cutter tooth roller 3 rotate down, material is thrown something and fed in charging aperture 4, two staggered engagements of cutter tooth roller 3, by crushing material after material enters, owing to crushing cutter 7 is separated by shim 8, crushing cutter 7 spacing is made to become big, convenient heat radiation, by shim 8 increasing heat radiation area, is conducive to heat radiation。

For ensureing the intensity of teeth 9, described teeth 9 assume diamond in shape structure, teeth 9 tip towards identical with cutter tooth roller 3 rotation direction。While ensureing the bigger dense degree of teeth 9, in order to increase the width of teeth 9 as far as possible, described crushing cutter 7 is fitted tightly fixing blade by two and forms, and the circumference side of each blade is evenly arranged with teeth 9, and the teeth 9 on two blades shift to install。

Described crushing cutter 7 diameter is R, and described shim 8 diameter is r, and its numerical relation is R=r, only has teeth 9 and protrudes from axle rod, has good rigidity, and crushing cutter 7 is maximized with shim 8 contact area, it is ensured that dissipate heat availability。Described crushing cutter 7 thickness is H, described shim 8 thickness is h, its numerical relation is H < h, crushing cutter 7 operationally produces heat and is diffused on shim 8, shim 8 is bigger than the thickness of crushing cutter 7, the heat avoiding both sides crushing cutter 7 accumulates on shim 8, dispel the heat the in time heat of the crushing cutter 7 also simultaneously preventing both sides of guarantee equipment interferes, accumulation, guarantee equipment safety, the trough body structure that teeth 9 on the crushing cutter 7 of both sides are open with shim 8 composition, and shim 8 adopts aluminium to make, shim 8 is bigger than the thickness of crushing cutter 7, make in cutter tooth roller 3 rotation process, in cell body, air easily flows, the heat produced on crushing cutter 7 distributes in time through shim 8, guarantee equipment simultaneously completes heat radiation in production, avoid the equipment damage problem that heat build-up causes, practical application connects discharging air exhauster at discharging opening, powder material is extracted out, flow by the air with air exhauster, extraneous Cryogenic air is sucked by charging aperture, improve the heat-sinking capability of equipment further。

Described two groups of cutter tooth rollers 3 respectively high speed discaling roll and low speed discaling roll, the teeth 9 of engagement place low speed discaling roll set up, the teeth 9 of high speed discaling roll are arranged downwards, and the rotating ratio of high speed discaling roll and low speed discaling roll is 1:1500 to 1:2000, and shim 8 side of described low speed discaling roll is also equipped with teeth 9。Owing to rotating speed limits, material will be held by low speed discaling roll by the teeth 9 set up, and by low speed discaling roll, material slowly fed engagement place, material is quickly smashed by high speed discaling roll by teeth 9, material is made to complete crushing operation, speed difference due to high, low speed discaling roll, when low speed discaling roll turns over a unit angle, high speed discaling roll has been rotated through 1500-2000 unit angle in engagement place, that is the material length that on low speed discaling roll, unit angle is corresponding is cut to 1500-2000 part by high speed discaling roll, thereby ensures that the granularity of material。

Time actually used, owing to the cell body between the teeth 9 on two crushing cutters 7 and shim 8 easily clamping material, the problem causing plug tooth, in order to solve this problem, described shim 8 side is also equipped with teeth 9, when cutter tooth roller 3 relatively rotates, teeth 9 support material rubs on relative shim 8, the problem namely efficiently solving plug tooth, makes again crushing material more thorough, also increase the area of shim 8 side, it is ensured that radiating effect preferably simultaneously。

This utility model adopts two opposed cutter tooth rollers to complete the fragmentation procedure of material, reduce the equipment requirement for material, material is carried by means of low speed cutter tooth roller, eliminate the setting of general pulverizer upper sieve plate, make bulk, strip, plate material can both be pulverized preferably, avoid sieve plate blocking, reduce maintenance time, compared to prior art, there is better crushing effect, occupation area of equipment greatly reduces, and owing to producing the minimizing of equipment, reduce energy resource consumption, reduce labor strength, heat radiation is simultaneously completed in production during equipment work, maintain easily, it is greatly improved production efficiency。
