Description
Technical field
The invention belongs to metallurgy, building materials, electric power, coal industry grinding purposes roller abrasive dust mill for sleeping in equipment, relate to grinding device of air swept horizontal roller mill especially.
Background technology
At present, the known milling equipment that is used for metallurgy, building materials, electric power, coal industry mainly is ball mill, roll squeezer and horizontal roll grinder.The deficiency of ball mill milling equipment is: efficient is low, and capacity usage ratio is low, in grinding process, the mill feed material grinding has arrived any degree, whether reached the technology requirement, in the actual production operation, can't accurately control, thereby can produce grinding or owe grinding; The material mill is meticulous when crossing grinding, has consumed energy more and has belonged to waste; Do not reach the grinding fineness requirement when owing grinding, cause product fineness defective.Roll squeezer and horizontal roll grinder are that grinding process can't accurately be controlled with the charging of gravity type mode, natural centrifugal force+natural gravity formula mode discharging, has " edge effect " problem, and drying capacity is poor, can not handle the big material of moisture, and grinding effect is affected.
Summary of the invention
The purpose of this invention is to provide a kind of novel grinding device.Be intended to avoid the deficiencies in the prior art.
Technical scheme of the present invention is: a kind of grinding device of air swept horizontal roller mill, comprise that the inner surface of drive unit drive is provided with the rotating cylinder of lining and abrasion-proof backing block, bracing or strutting arrangement, grinding roller, feed arrangement, drawing mechanism, device for exerting and sealing device, rotating cylinder is supported on the bracing or strutting arrangement, the rotating cylinder both sides are respectively equipped with entrance and exit, entrance side is equipped with the inlet seal device, outlet side is equipped with the exit seal device, inlet is connected with the gravity feed arrangement by inlet seal device upper outside wall, outlet is connected with drawing mechanism by exit seal device upper outside wall, grinding roller is contained in the below in the rotating cylinder, the axle of grinding roller passes rotating cylinder inlet seal device and is connected with device for exerting with the exit seal device, it is characterized in that: described rotating cylinder entrance side also is provided with an outlet, the outlet of entrance side is connected with the drawing mechanism of entrance side by inlet seal device upper outside wall, the rotating cylinder outlet side also is provided with an inlet, the inlet of outlet side is connected with the gravity feed arrangement of outlet side by exit seal device upper outside wall, promptly establish an inlet and an outlet at each end of cylindrical shell, being two advances two and goes out form, described feed arrangement is provided with the hot blast inlet port, the outer end of hot blast inlet port is connected with equipment hot air generator outward, described drawing mechanism is a wind-force negative pressure cavity drawing mechanism, and promptly wind is swept the formula drawing mechanism.
Grinding device of air swept horizontal roller mill of the present invention is characterized in that: described wind-force negative pressure cavity drawing mechanism is that an air port is set on drawing mechanism, and the outer end in air port is connected with equipment wind-force negative pressure device outward.
Grinding device of air swept horizontal roller mill of the present invention is characterized in that each end inlet porting and outlet of described cylindrical shell, the position of the inlet of entrance side the exit position tiltedly below, the position of the inlet of outlet side is at the oblique upper of exit position.
Principle of the present invention is: material relies on the gravity effect to enter in the rotating cylinder of horizontal roller mill by the rotating cylinder entrance side, material by grinding after, under action of centrifugal force, rise along the rotary barrel inwall, when rising to a certain height, under the effect of gravity, will be by the material of grinding as the parabolic motion rotating cylinder body minimum point that falls to circling round, simultaneously because drawing mechanism is that wind is swept the formula drawing mechanism, under suction function, risen to along the rotary barrel inwall in the process that leaves by the material fine particle of grinding, extracted out outside the mill by the effect of sweeping of the wind of drawing mechanism, the coarse granule material that does not reach the grinding requirement is then fallen the minimum point of rotary barrel, proceeds grinding with follow-up mixing of materials of going into to grind, the circulation grinding is finished grinding work so continuously.Owing to be provided with the hot blast import on feed arrangement, drawing mechanism is that wind is swept the formula drawing mechanism, and under suction function, dry-heat air enters cylindrical shell with material, and wind is swept when acting on convey materials, the oven dry material, and both carry out grinding and oven dry simultaneously.
Compared with prior art, advantage of the present invention is: 1, principle advanced person, project organization is reasonable, has both overcome the low problem of ball mill capacity usage ratio, efficiently solves roll squeezer " edge effect " problem.2, possess drying capacity, the big problem of solution material moisture, both carry out grinding and oven dry simultaneously, saved the drawbacks that drying plant takes up an area of greatly, auxiliary device is many, increase is invested are set separately.3, equipment operates steadily, and eliminates vibration, has reduced and has crossed grinding or owe the grinding phenomenon, makes the product yield and quality be improved energy savings.4, the structure that goes with each other all the time is improved the input and output material efficient of equipment.
