Description

Impact breaker

Technical field

The invention belongs to the manufacture of cement field of mechanical technique, be specifically related to a kind of impact breaker, be used for lime stone and clay mixing fragmentation.

Background technology

The reason of knowing as those of skill in the art, the raw material of producing cement mainly is lime stone and clay product, the method that these two kinds of materials are mixed mainly contains two kinds: the one, and fragmentation or title are broken separately respectively, store respectively and pre-homogenizing, the batching station of taking out and being transported to grinding workshop section respectively feeds the grinding machine grinding according to a certain percentage.Because this method needs the broken and storage homogenizing induction system of two covers, therefore is not subjected to thinking highly of of industry; The 2nd, lime stone, these two kinds of raw materials of clay are sent into a cover system in proportion simultaneously and carried out fragmentation, industry is called and is mixed fragmentation, because the compound of this fragmentation also only needs a cover storage homogenization system naturally, the equipment amount of coming into operation is few, so the application of this method is relatively more than the former.Especially, when clay is the high-ductility high-moisture, fragmentation is not only difficult separately, and it is very easily sticky in course of conveying after broken with the conveyor belt surface of rubber mass, bonding and stopping up in the running scraper-trough conveyer, the accumulation horizon compacting is difficult to take in accumulation, and tumbling in the process again, conglomeration becomes bulk, or the like, thereby extremely unreliable to producing.Yet, the rerum natura (physical property) through mixing the material after broken greatly for a change, viscosity weakens, mobile increasing, the transportation access is all not difficult, the advance of obviously mixing fragmentation is self-evident.

It is impact breaker that lime stone, clay are mixed broken type, not strange for the structure and the operation principle people of this disintegrating machine.For example in the technical scheme of the disclosed birotor single hop of Chinese patent Granted publication CN2678765Y hammer mill housing, disclose to some extent; And for example in the technical scheme of the use for repairing rotor of hammer type crusher power assisting device that Chinese patent application publication number CN1958165A introduces, as the application examples of this scheme impact breaker Fig. 4 signal of this patent application (specifically by) is disclosed.

With regard to the fragmentation requirement of impact breaker, in order to prevent that the bulk walk from entering disintegrating machine and causing being difficult to mixing and then causing with lime stone immediately the obstruction of rear portion double-edged fine-toothed comb, therefore set up clay-cutting machine at the head of clay batcher, the structure of this kind clay-cutting machine can be passed through Chinese patent Granted publication CN2895004Y detail knowledge.

The present structure that is used for lime stone, clay are mixed broken impact breaker is as by shown in Figure 1, comprises the disintegrating machine body 1 with broken working chamber 3 and is hubbed on clay that being used in the disintegrating machine body 1 will enter into broken working chamber 3 mixes fragmentation with the lime stone raw material a pair of first, second broken rotor 2a, 2b.This mixing crusher can adapt in the compound 15% the broken requirement of mixing of sticking wet shape clay comprises lime stone weight, yet, because the amount of allocating into of clay is bigger in some cases, can reach 30%, therefore be difficult to adapt to and mix broken requirement, trace it to its cause is that the clay content of the existing feed mode a pair of rotor broken material that can't make disintegrating machine is even, because mix the broken two platen formula batcher feed that need, mainboard formula batcher and disintegrating machine occupy on the same axis, and it draws off and send into disintegrating machine with lime stone by the material hole; And inferior apron feeder occupy the axis side, it delivers to clay on the lime stone bed of material of mainboard formula batcher, the material bottom of promptly giving disintegrating machine is a lime stone, the top layer is a clay, when they dump into disintegrating machine through the great wheel of feeding machine 4, top layer material is that clay mainly inclines and combines in the second broken rotor 2b, and underlying material to be lime stone mainly topple over has given the first broken rotor 2a.Therefore too much clay enters the second broken rotor 2b seam that can cause combing and sticks with paste, and causes buildup in the machine, reduces crushing efficiency, increases the wearing and tearing of work.And when first, second broken rotor 2a, 2b worked, the load of the second broken rotor 2b was big, and the load of the first broken rotor 2a is little, therefore owing to the unbalanced crushing efficiency that influences of first, second broken rotor 2a, 2b load.Aforementioned factor has become the existing broken subject matter of mixing.

The industry of the disintegrating machine of home and abroad production is at present all being tried to explore, and the phase gets and obtains to break through, but has not both seen have the crushing system of success to go on the market up to now, also hears the relevant report that success is arranged.The technical scheme that the present invention will introduce below produces under this background.
