Description
Technical field
The utility model is related to a kind of cementitious material grinding devices.
Background technology
The fineness grading of concrete gel material has extremely important influence for the durability of concrete material,
Concrete is mixed and stirred, is poured, in construction process.In order to ensure that architecture quality requires grinding cementitious material mostly, to be promoted
Concrete performance, since concrete unavoidably will produce pore in forming process and gelling hole exists for microcosmic go up
Interior all concrete dynamic modulus, these gaps will have a direct impact on the impermeability of concrete in the case of unicom, and permeability therefore can pole
Increase greatly, physical-chemical reaction caused by hazardous medium intrusion can generate huge negative effect to the durability of concrete.And
Domestic and foreign scholars show to improve the permeability of concrete under study for action at present.One of which method is exactly by grinding gelling material
Material, reduces its fineness grain size so that and during material is conserved and is molded, the minimum material of fineness particle can block hole, from
And achieve the purpose that reduce concrete permeability, it was proved that this method has greatly for reducing concrete permeability really
Benefit.
At present in the cementitious material grinding test of laboratory, service machine mainly grinds storehouse rotation and provides centrifugal force drive
The objects such as all size the shape iron ball, the iron block that differ placed in storehouse and cementitious material rolling rotation by pounding, rubbing, with
And the mode rolled reduces material fineness.This mode grinding effect is bad, and required milling time is long, and the objects such as iron block turn over
Rolling percussion does the noise brought and also will produce influence to human body, environment.
The grinder of above-mentioned current laboratory applications expends the time, for being required in big experiment in material amount of grinding,
Due to inefficiency, it is unfavorable for experiment continuous operation.Iron block was tapped in the service life in grinding storehouse, and noise has for environment
Huge negative effect, and currently on the market it is few it is specific specialized be applied to laboratory in cementitious material grinding device, in view of
This, a kind of novel applicable cementitious material grinding device of design is with regard to very necessary.
Invention content
The purpose of this utility model is to overcome above-mentioned deficiency now provides a kind of cementitious material grinding device, for solving
Time-consuming for existing grinder, noise is big and leads to the problem of dust.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of cementitious material grinding device, it includes rack, grinding storehouse and driving motor, and the grinding storehouse has charging
Mouthful, capping is equipped on feed inlet, axis connection has a support shaft, grinding storehouse axis connection being ground in support shaft in rack
Multiple pressure rollers are installed, driving motor is connected by speedup sprocket wheel and deceleration sprocket wheel with support shaft and the transmission of grinding storehouse respectively in mill storehouse
It connects, support shaft drives multiple pressure roller synchronous backwards to rotate by drive sprocket.
Described capping one end and grinding storehouse are hinged, and other end is connect by screw with grinding storehouse.
It is equipped with material guiding hopper in grinding storehouse, the thinner one end of material guiding hopper is connected to feed inlet, the thicker one end of material guiding hopper and grinding
Storehouse inner wall connection.
It is equipped with receiver below grinding storehouse.
Each pressure roller is connect with multiple gears outside grinding storehouse respectively, and each gear engages successively.
The utility model has the beneficial effects that：In use, cementitious material is first placed in grinding storehouse by feed inlet, pressure is opened
Driving motor in roller, the pressure roller rotated using multiple sync directions, which can be ground cementitious material, to roll, due to rolling
It is to be carried out in storehouse is ground in closing, therefore the noise for grinding generation is small, dust is low and effect is good.In conclusion the utility model
It is simple in structure compared with prior art, grinding effect is good, environment protection health and production cost bottom, there is higher actual application value
It is high.
Description of the drawings
The utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is the cross-sectional view of the utility model,
Fig. 2 is structural schematic diagram of the utility model about multiple pressure rollers.
In figure：Rack 1, grinding storehouse 2, support shaft 3, deceleration sprocket wheel 4, speedup sprocket wheel 5, drive sprocket 6, pressure roller 7, driving electricity
Machine 8, material guiding hopper 9, capping 10, screw 11, receiver 12, feed inlet 21, gear 71.
Specific implementation mode
As shown in the 2 of Fig. 1, a kind of cementitious material grinding device, it includes rack 1, grinds storehouse 2 and driving motor 8, described
Grinding storehouse 2 has feed inlet 21, and capping 10 is equipped on feed inlet 21, and axis connection has a support shaft 3 in rack 1, grinding
2 axis connection of storehouse is equipped with multiple pressure rollers 7, driving motor 8 passes through 5 He of speedup sprocket wheel respectively in support shaft 3 in grinding storehouse 2
Deceleration sprocket wheel 4 is sequentially connected with support shaft 3 and grinding storehouse 2, and support shaft 3 drives 7 synchronous backward of multiple pressure rollers by drive sprocket 6
Rotation.Speedup sprocket wheel 5 is the first small tooth by being connected to first gear wheel of 8 one end of driving motor, being fixedly connected with supporting axis
The first chain on wheel and the first gear wheel of connection and the first pinion gear is constituted；Deceleration sprocket wheel 4 is by being connected to driving motor 8 one
Second pinion gear at end, with grind the second gear wheel that is fixedly connected of storehouse 2 and connect on the second gear wheel and the second pinion gear
