Description
Technical field
The present invention relates to a kind of new-type rubber grinder, be applicable to reclaimed rubber resources domain.
Background technology
At present, micelle after the fragmentation of the rubber such as junked tire, sebific duct is generally used for reclaimed rubber industry, in addition topmost purposes makes fine glue powder exactly, just fine glue powder can be called more than 40 object rubber powders, can be used for modified plastics, water-repellent paint, modifying road asphalt and directly adding in rubber manufacture process, thus, grind rubber powder and become an emerging industry gradually.
Existing flour mill install primarily of motor, belt gear, the main shaft utilizing belt gear to drive and end thereof movable grinding disc, hard-wired fixed millstone, be enclosed in dynamic, that fixed millstone is outside milling compartment, the compositions such as pay-off, wherein, movable grinding disc and fixed millstone are solid construction, and both have respective pedestal respectively.There are the following problems for it:
1, movable grinding disc and fixed millstone are solid construction, although ensure that the disk body rigidity of mill, but two mills temperature in milling process is high, processing again due to rubber powder is different from hard material, rubber flexible, and rubber To Be Protected from Heat, on the mill of high temperature, micelle can not be ground into fine powder, reason is, namely desulfurization is started after elastomeric material preheating, reduction, now there is deformability characteristics, two mills can be bonded together at once, the rotation of mill is run and produces great resistance, namely paste mill alleged in producing, not only hinder normally carrying out of producing, reduce production efficiency, add the maintenance cost of the parts such as mill simultaneously.The existing cooling means to movable grinding disc and fixed millstone also just cools surface both usually, and cooling effect is not good, can not fundamentally solve the problem.
2, enough normal pressures to be had between two mills of flour mill, the cutter of micelle and disc surface just can be made to produce enough large frictional force, thus micelle is levigate, in order to achieve the above object, existing flour mill all improve as much as possible dynamic, the rigidity of fixed millstone pedestal separately, but owing to will be convenient to dismantle mill, be convenient to powder delivery, powder storehouse needs the reasons such as cooling, flour mill two mill can not keep the necessary depth of parallelism under long-term duty, be easy to cause eccentric wear, substantially reduce the service life of mill, cause the particle size range of product to distribute wide simultaneously, product percent of pass is low.
3, in order to reach high-yield and high-efficiency object, usual employing high power motor, but when high power motor is by belt pulley drive main shaft High Rotation Speed, when belt pulley is rotated simultaneously produce larger tension force pass to main shaft and on movable grinding disc, greatly reduce the running accuracy of movable grinding disc, have a strong impact on the qualification rate of product.
Summary of the invention
The object of the invention is to provide a kind of new-type rubber grinder solving in existing rubber grinder operation process the problem of dynamic, fixed millstone high temperature, eccentric wear, running accuracy difference.
Technical scheme of the present invention is:

Above-mentioned new-type rubber grinder, is provided with catch and seal receptacle between described cooling water pipeline and annular backwater road, prevents string water object to reach.
Above-mentioned new-type rubber grinder, the inner surface in corresponding described cooling water circulation chamber, described top layer that is dynamic, fixed millstone is set to zigzag respectively, to increase heat exchange area, strengthens cooling effect.
Above-mentioned new-type rubber grinder, thrust ball bearing is provided with between described main shaft and casing neck bush, described casing end flange utilizes screw to be fixedly connected with described milling compartment, described fixed millstone is fixed on described milling compartment sidewall, described casing and milling compartment are fixed on same base, when described dynamic, when fixed millstone produces tension force in milling process, the tension force that movable grinding disc produces is passed to casing by the thrust ball bearing on main shaft, casing passes to milling compartment, and cancel out each other with the tension force that fixed millstone on milling compartment produces, thus ensure the axiality of two mills, prevent eccentric wear, significantly improve the service life of mill and the qualification rate of product, decrease the rigidity requirement of equipment operation to pedestal simultaneously.
Above-mentioned new-type rubber grinder, described casing rear end is fixedly connected with the bonnet with cylindric afterbody, on the cylindric afterbody that the belt pulley of described belt gear utilizes bearing to be installed on described bonnet and axial location, the power intake of described main shaft passes the cylindric afterbody of described bonnet and between sleeve is housed, described sleeve exposed junction is fixedly connected with described belt pulley side, while revolving force is passed to main shaft by sleeve by belt pulley, again its rotational strain is passed to casing by bonnet, born by casing, thus ensure that the running accuracy of movable grinding disc, eliminate the vibration that produced by belt pulley to the impact of movable grinding disc.
Above-mentioned new-type rubber grinder, described pay-off is the spiral pushing device be communicated with fixed millstone.
Above-mentioned new-type rubber grinder, described abrasive dust tool section adopts tungsten carbide button, effectively extends the service life of mill.
The invention has the beneficial effects as follows: because dynamic, fixed millstone are respectively equipped with bifurcation structure, add area of dissipation, improve radiating rate, significantly improve the cooling effect of mill in production process, the phenomenon avoiding " sticking with paste mill " produces, and ensure that normal that rubber powder is produced carries out in order, significantly improves production efficiency, improve the service life of the parts such as mill, reduce maintenance cost.
