Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, further illustrate the technical solution of the utility model below in conjunction with accompanying drawing by detailed description of the invention.
The utility model provides a kind of large-scale vertical grinder, and this grinder can increase the contact area between raw material and abrasive media, and then reduces the energy consumption needed for grinding.As shown in Figure 1, this grinder comprises base 5 and is arranged on the grinding cylinder 1 on base 5, and in the present embodiment, the quantity of grinding cylinder 1 is one, but this practicality is newly not limited thereto, and also can be multiple grinding cylinder 1 cascaded structure in other embodiments.Be provided with motor 2 above grinding cylinder 1, motor 2 is connected with lapping device 4 and rotates in order to drive lapping device 4.Wherein also be provided with reductor 3 between motor 2 and lapping device 4, the output of reductor 3 is connected with lapping device 4 by shaft coupling 6, and the input of reductor 3 is connected in order to the speed of lapping device 4 to be adjusted in the scope of needs with the output of motor 2.The advantages such as owing to adopting direct coupled structure between motor 2 and decelerator 3, thus make this lapping device have smooth running, shake little, noise is low, and start and stop are convenient.
Lapping device 4 is in order to the raw coal after grinding water coal slurry or fragmentation, described lapping device 4 stretches in sand cylinder 1, flow-stopping plate is provided with and grinding cylinder inwall is obtained by high-abrasive material in grinding cylinder 1, flow-stopping plate vertical distribution on the inwall of grinding cylinder 1, in other embodiments flow-stopping plate can Spiral distribution on the inwall of grinding cylinder 1; Or vertical, Spiral distribution exists simultaneously.Grinding cylinder 1 top is provided with upper end material mouth 11 and abrasive media entrance 12, and grinding cylinder 1 bottom is provided with lower end material mouth 13 and abrasive media outlet 14.
It should be noted that, entering grinder material can be broken rear raw coal or the water-coal-slurry after conventional mill corase grind.When after pan feeding is broken during raw coal, input and output material mode is upper feeding bottom discharge, and now upper end material mouth particular location should in grinding cylinder upper end; When pan feeding is through the water-coal-slurry after conventional mill corase grind, input and output material mode can select upper feeding bottom discharge or lower charging top discharge.The utility model word and drawing statement in input and output material mode be upper feeding bottom discharge.
Pan feeding range of choice of the present utility model is wide, and when selecting to adopt broken rear feed coal, its grind size is≤10mm; Also can select the water-coal-slurry after conventional mill, grinding maximum particle diameter is≤3mm, and average grain diameter is 100 ~ 150 μm, and wherein≤75 μm account for 25 ~ 55%.When grind raw material be fragmentation after raw coal time, material from upper end material mouth 11 enter in grinding cylinder 1, after grind from lower end expect mouth 13 send.
Abrasive media is spherical structure, and the diameter of abrasive media in grinding cylinder 1 described in the present embodiment is incomplete same.In other words, the abrasive media of two kinds of specifications (i.e. diameter) is at least comprised in the present embodiment.The area contacted with each other in process of lapping due to the abrasive media of same diameter is definite value, and then the contact area between raw material and abrasive media is reduced, in order to can contact area be increased, the abrasive media of plurality of specifications in the present embodiment, is adopted to solve the problems referred to above.Select different size abrasive media simultaneously, for the grinding of different material granularity selection, disposablely can grind the material to release mesh.
Lapping device 4 comprises and grinding shaft 41 and grinding shaft 41 is uniformly distributed from top to bottom and is no less than two-layer abrasive disk 42, and described abrasive disk 42 is evenly distributed with grinding rod.Particularly, abrasive disk 42 quantity is 5 ~ 30 layers, can select the abrasive disk number of plies according to actual needs; Abrasive disk 42 is evenly equipped with 3 ~ 12 grinding rods, and removably connects between described grinding rod and abrasive disk 42.Grinding rod is easy loss product, and this kind of structure can easy disassembly and maintenance, and grinding rod only needs the grinding rod more renewed after damaging, without the need to the abrasive disk replacing at grinding rod place that will damage.Motor 2 drives grinding shaft 41 in the process of running up by reductor 3, drives abrasive media degree of depth disturbance in grinding cylinder 1 that grinding material is levigate fast, and then rationally, effectively make use of pressure potential and friction kinetic energy.
Grinding cylinder 1 internal layer is regular polygon structure; And the ratio of height to diameter of grinding cylinder 1 is 1:1 ~ 5:1.Grinding cylinder in the present embodiment adopts above-mentioned ratio of height to diameter can alleviate or avoid grinding cylinder too high and occur rocking, and the grinding cylinder simultaneously within the scope of this kind of ratio of height to diameter is to add man-hour also more easy, and processing cost is corresponding reduction also.
When grinding, this lapping device can not ensure that the material ground out can all meet the requirements, for this reason, upper end material mouth 11 or material mouth 13 place, lower end are also provided with stainless steel grating and auxiliary power unit in order to filter the material after grinding, all grinding requirement can be met to make the material of discharging opening, wherein auxiliary power unit is in order to prevent feed blocking stainless steel grating, it should be noted that, if when feeding manner is upper entering and lower leaving, lower end material mouth is provided with stainless steel grating and auxiliary power unit, if when feeding manner is bottom in and top out, upper end material mouth is provided with stainless steel grating and auxiliary power unit.
Grinding cylinder 1 is also provided with overfall 15, and overfall 15 is in order to observe the situation that in grinding cylinder, whether material overflows.In the present embodiment, abrasive media exports 14 when being mainly used for equipment general overhaul and is released by the abrasive media in grinding cylinder 1.
The utility model adopts vertical installation cylindrical shell grinding material, when being full of abrasive media and material in grinding cylinder, makes grinder obtain high power density, thus the milling time of fine granular materials is shortened greatly.The utility model is compared with traditional rod mill or ball mill, and owing to adopting the abrasive media of different-diameter, abrasive media filling rate is high, improve the grinding efficiency of material, material and abrasive media contact area increase, and make water-coal-slurry grind power consumption≤15kWh/t, have effectively saved the energy.
The utility model can according to the characteristic of material, and select to adopt upper feeding, bottom discharge mode or lower charging, top discharge mode, be particularly suitable for concentration (20% ~ 50%) material in grinding, and separate unit production capacity is large, product granularity easily regulates.
