Abstract

The utility model discloses a pulverizer relates to pulverizer manufacturing technical field, be equipped with the crushing room that feed inlet and rear end were equipped with the discharge gate including the front end, smash and indoorly to wear to be equipped with a plurality of blade discs through the pivot, crushing room is equipped with along a plurality of crushing chamber that ejection of compact direction is reduced in proper order, every all be equipped with one in smashing the chamber the blade disc, these steadily decrease and the interval is worn the dress and is in in proper order along ejection of compact direction for the external diameter of blade disc in the pivot, adjacent be equipped with flow guide disc between the blade disc. Compared with the prior art, the utility model discloses can solve current pulverizer's comminuted inefficiency and the short problem of blade disc life.

Description

Pulverizer
Technical field
The utility model relates to pulverizer manufacturing technology field, especially a kind of for the pulverizer in lithopone production line.
Background technology
In the production of lithopone, be, by pulverizer, large-sized solid material of the bulk made is crushed to required size.Existing a kind of pulverizer, this pulverizer comprises front end and is provided with the pulverizing chamber that charging aperture and rear end are provided with the straight barrel type of discharging opening, and is coated with the identical cutterhead of multiple size successively by rotating shaft in described pulverizing chamber, described rotating shaft is provided with impeller in charging aperture place; Described rotating shaft is installed in frame respectively by the bearing block being located at described rotating shaft two ends.In use there are the following problems for this pulverizer: 1, entering material from charging aperture is pass through in pulverizing chamber the centrifugal action produced by vane rotary, pulverized by multiple cutterhead successively, but because pulverizing chamber is straight barrel type and to pulverize cutterhead external diameter identical, after material is pulverized cutterhead impact by first, warp often not yet enters next cutterhead, just be drawn to outlet under the influence of centrifugal force, often again put into from charging again pulverize because the particle diameter of material pulverized does not reach requirement, crushing material efficiency is low; 2, due to the impact several times of cutterhead and material in operation process, a large amount of heats can be produced in pulverizing chamber, if the time of Continuous maching operation is longer, a large amount of heat assembled will cause pulverizing body and occur that temperature is too high, and this will shorten the normal service life of cutterhead and machine greatly.
Utility model content
The problem that the utility model solves is to provide a kind of pulverizer, with the problem that the crushing material efficiency solving existing pulverizer low and cutterhead service life is short.
In order to solve the problem, the technical solution adopted in the utility model is: this pulverizer comprises front end and is provided with the pulverizing chamber that charging aperture and rear end are provided with discharging opening, multiple cutterhead is coated with by rotating shaft in described pulverizing chamber, described pulverizing chamber is provided with the multiple crushing chambers reduced successively along discharging direction, a described cutterhead is equipped with in each described crushing chamber, the external diameter of cutterhead described in these successively decreases successively along discharging direction and interval is installed in described rotating shaft, between adjacent described cutterhead, be provided with flow guiding disc.
Owing to have employed technique scheme, the utility model compared with prior art has following beneficial effect: 1, because pulverizing chamber is provided with the multiple crushing chambers reduced successively along discharging direction, material just moves after being pulverized cutterhead impact by first under the influence of centrifugal force backward, impacted by cutterhead in the cutterhead entering next crushing chamber after the chamber wall with next crushing chamber collides smoothly, improve the degradation rate of material; 2, multiple cutterhead interval to be contained in rotating shaft and to be provided with flow guiding disc between adjacent cutterhead, reduce and make produce in pulverizing chamber the phenomenon of amount of heat because cutterhead is arranged in order impact material continuously, flow guiding disc can send by the material after last cutterhead pulverizing into next crushing chamber very soon simultaneously, improves the service life of pulverizer.
The utility model is rear along the direction of discharging.
Accompanying drawing explanation
The structural representation of Fig. 1 the utility model embodiment.
Detailed description of the invention
Below in conjunction with attached Example, the utility model is described in further detail:
Pulverizer as shown in Figure 1 comprises front end and the pulverizing chamber 4 that discharging opening 8 is equipped with in charging aperture 3 and rear end is housed, pulverizing chamber 4 is fixed on frame 1, the present embodiment is coated with three cutterheads by rotating shaft 7 in pulverizing chamber 4, rotating shaft 7 is installed in frame 1 by the bearing block being contained in two ends, in one end of rotating shaft 7, belt pulley 2 is housed, belt pulley 2 is connected with motor by belt; Pulverizing chamber 4 is provided with three crushing chambers that chamber internal diameter reduces successively along discharging direction, is equipped with a cutterhead in each crushing chamber, is respectively the cutterhead 10 of cutterhead the 11, three crushing chamber of cutterhead 5, second crushing chamber of the first crushing chamber; The external diameter of these cutterheads successively decreases successively along discharging direction and interval is installed in rotating shaft 7, the rotating shaft 7 between adjacent cutterhead 5, cutterhead 11 and cutterhead 11, cutterhead 10 is coated with respectively two people's flow guiding discs 6.
During work, material enters from charging aperture 3 and is just moved backward under the influence of centrifugal force by after the impact of first pulverizing cutterhead, impacted by cutterhead in the cutterhead entering next crushing chamber after the chamber wall with next crushing chamber collides smoothly, because pulverizing chamber 4 is provided with the multiple crushing chambers reduced successively along discharging direction, improve the degradation rate of material; Because three cutterheads are that interval to be contained in rotating shaft 7 and to be provided with flow guiding disc 6 between adjacent cutterhead, flow guiding disc 6 can send by the material after last cutterhead pulverizing into next crushing chamber very soon, improve the service life of pulverizer, reduce simultaneously and make produce in pulverizing chamber the phenomenon of amount of heat because cutterhead is arranged in order impact material continuously.
