Abstract

The utility model provides a super fine dust-proof crusher used in industrial departments, such as thermal power generation, mining, metallurgy, refractory materials, etc., comprising a box body having a feed port, an abdominal cavity and a screen plate, a rotary shaft arranged on the box body as well as a drum wheel with a hammer head arranged on the rotary shaft and positioned in the abdominal cavity. The utility model is characterized in that the feed port on the box body is provided with a coarse dust collecting chamber having an impact lining board on the inner wall of the box body and communicated with the abdominal cavity. The feed port of the box body is provided with a movable dust-proof baffle plate. The utility model has the advantages of small granularity of crushed materials, good dust-proof effect and low energy consumption.

Description

The carefully dustproof disintegrating machine of superelevation

The utility model relates to a kind of industrial departments such as thermal power generation, mine, metallurgy, refractory material that are used for, especially for the carefully dustproof disintegrating machine of the superelevation of cement slurry and grog.

Disintegrating machine belongs to and runs up, powerful work, the equipment of often dismantling and keeping in repair.The patent No. is advantages such as the dustproof fine crusher of the impact type of CN91230167.8 improves existing fine crusher, and it is better to have dustproof effect, and the broken material granularity is less.But this dustproof fine crusher still exists following shortcoming:

1, material and gas that the high speed that driven by high speed rotary impact hammer is rotated do not have the settlement space of circling round, and dust is easy to discharge contaminated environment from charging aperture.

2, the surfaces of revolution axle center of jump bit overlaps substantially with the sieve plate axle center, the hitting power that material can only be hammered into shape in this interval, and friction and Extrusion power is very little, easily cause the sieve seam to stop up, and the broken material granularity is limited.

In view of above reason, the purpose of this utility model is in order to provide a kind of broken material granularity little, good dustproof effect, the carefully dustproof disintegrating machine of the superelevation that comminution energy conssumption is low.Another purpose of the present utility model is in order to solve the problem of sieve seam obstruction.

The purpose of this utility model is achieved like this: the casing that contains charging aperture and abdominal cavity and sieve plate is arranged in the utility model, be loaded on the rotating shaft on the casing, be positioned at the abdominal cavity and be loaded on the drum that contains tup in the rotating shaft, it is characterized in that the thick broken chamber (referring to Fig. 1) of gathering dust that contains the counterattack liner plate (13) that is loaded on the cabinet wall that communicates with the abdominal cavity being arranged being positioned at the charging aperture place on the casing.

Movable dustproof baffle plate (referring to Fig. 1) is equipped with at above-mentioned casing charging aperture place.

The thin broken back cavity that contains the counterattack liner plate (15) that is loaded on the cabinet wall that communicates with abdominal cavity and the thick broken chamber of gathering dust is arranged in the above-mentioned casing, and thick broken gathering dust has Material control mouth (referring to Fig. 1) between chamber and carefully broken back cavity.

The working face of the tup on the above-mentioned drum is arc surface (referring to Fig. 1).

The working face axis of rotation of above-mentioned tup departs from the axle center of sieve plate, forms by the wide top clearance that narrows down (referring to Fig. 1) between the working face of tup and sieve plate.

During the novel work of this reality, rotating shaft is connected with motor, material is entered by charging aperture, wash movable dustproof baffle plate open, hit by tup and enter thick broken vacuum chamber, impinge upon on the thick broken vacuum chamber counterattack liner plate, in automatic landing process, be subjected to the strike of tup once more, material less than the Material control mouth enters thin broken back cavity, impinge upon on the thin broken back cavity counterattack liner plate, the strike that continues to be subjected to once more tup in automatic landing process enters bottom, casing abdominal cavity, and thin material is discharged from the sieve seam of sieve plate, and thick material continues to be subjected to the strike of tup.In bottom, casing abdominal cavity, because the top clearance that sieve plate and tup motion working face form is to be narrowed down by wide, so material also will be subjected to the shear extrusion power of tup and be broken once more and discharge sieve and stitch in this interval.Do in the high speed rotary motion process at tup, dusty gas and the fine particle that driven by high speed rotary hammer head circles round in the thick broken chamber of gathering dust, weakens, sedimentation, so dusty gas can not discharged from charging aperture.

The utility model is provided with two crusher chamber, and wherein the promptly thick broken chamber of gathering dust, a chamber makes the sedimentation of circling round of thick broken material and gas, has reached dustproof effect.Be provided with movable dustproof baffle plate between the chamber at charging aperture and thick broken gathering dust, material is washed the dustproof baffle plate of activity open and has been entered the thick broken chamber of gathering dust, the open degree of movable dustproof baffle plate is how many automatic controls by charging, reached the dustproof optimum efficiency, the history of the existing feed of crusher mouth ash discharge dirt that is through with.The tup working face is a circular arc, is provided with the top clearance that is narrowed down by wide between sieve plate and the tup, and material not only overwhelms but also pushed by fricting shearing, and the obstruction of sieve seam has been avoided in easier fragmentation of material and discharge, and the broken material granularity is little.

It is little to the utlity model has the broken material granularity, good dustproof effect, and environmental pollution is little, and comminution energy conssumption is low, few easy workout part, advantages such as repair and maintenance convenience.Purposes is wide, is specially adapted to the fragmentation of cement slurry and grog.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation.

Referring to Fig. 1, be provided with charging aperture 2 in the casing 1.On abdominal cavity 3 lower part box sieve plate 4 is housed, rotating shaft 5 is contained on the casing and is positioned at the place, abdominal cavity is equipped with the drum 7 that contains several tups 6.The working face 8 of each tup is an arc surface.The working face axis of rotation 9 of tup departs from the axle center 10 of sieve plate.The work surfaces of revolution of tup and sieve plate have formed by the wide top clearance that narrows down 11.The dustproof baffle plate 12 of the activity of axle on 18 that is contained on the casing is arranged at the charging aperture place.Have and be loaded on containing of feeding inlet thick the prevent dust chamber 14 and the thin broken back cavity 16 that contains the counterattack liner plate 15 that is loaded on the casing of breaking of the counterattack liner plate 13 on the casing in casing, slightly breaking gathers dust chamber 14 and carefully break 16 of back cavities Material control mouth 17.
