Abstract
The utility model pertains to a rotary scraper used for palletizing disk of sinter pellets, more particularly, which relates to an embedded and integrated high wear-resistant rotary scraper. The utility model comprises a body of the rotary scraper and a scraper head and is characterized in that the part of the scraper head of the body is provided with a plurality of wear-resistant blocks in embedding, which can be six to twelve blocks. The wear-resistant block which is made of high purity silicate materials has external arc surfaces and internal plane surfaces; an upper end of the body, which is close to the scraper head, is sleeved with a protective sleeve. The utility model has the advantages that as the wear-resistant blocks are embedded in the scraper head of the body of the scraper, an integrated structure is formed by the scraper head and the scraper body, which avoids scraper head releasing from the scraper and effectively prevents cracking and releasing caused by the impact by the bump of impurity in the pellet to the wear-resistant blocks; in addition, the protective sleeve is arranged at the outer side of a scraper rod, which effectively prevents the defect of thinning of the neck part of the scraper rod caused by wearing, and compared with similar products, the service life of the scraper of the utility model is prolonged about three months.
Description
Technical field
The utility model belongs to the revolving scraper of using on a kind of sintered balls nodulizing balling disk (-sc), especially relates to a kind of inserted integrated high abrasion revolving scraper.
Background technology
In the production of sintered balls nodulizing, revolving scraper on the balling disk (-sc) is main normal consumption spare part, because of contacting of iron powder on the balling disk (-sc) and revolving scraper is unusual intensive abrasive wear, breeze is very big to the wear loss of scraper, and the work-ing life of the revolving scraper of general pellet formation producer is all at 20～60 days.For head it off, people improve scraping jet blade, its structure is: the jet blade of being made by high-abrasive material of scraping is fixed on the cutter hub by flush bolt, though this revolving scraper has improved wear resisting property, the frequent loose or dislocation of joint bolt, the scraper that in use are prone between cutter head and the knife bar turn around, and wear-resisting part is damaged, broken away from, problems such as the scraper neck attenuates, need overhaul often, increase labor strength, reduce the operating rate of balling disk (-sc).
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, wear resisting property good, the inserted integrated high abrasion revolving scraper of long service life.
The purpose of this utility model realizes by following technical proposals.
According to the inserted integrated high abrasion revolving scraper of the utility model, comprise revolving scraper body, cutter head, it is characterized in that the embedded polylith wear-resistant block that is equipped with at the cutter head place of scraper body, be with protective sleeve in the upper end of the close cutter head of revolving scraper body.
Described wear-resistant block can be 6～12.
Described wear-resistant block outside surface is a cambered surface, and internal surface is the plane.
Described wear-resistant block adopts highly purified silicate material to make.
The utility model has the advantages that: since at the cutter head place of scraper body the embedded polylith wear-resistant block that is equipped with, make cutter head and cutter hub formation integrative-structure, on the scraper cutter hub, do not have other part, so just avoided the scraper phenomenon that turns around; And owing to form certain slit between wear-resistant block and the wear-resistant block, having prevented effectively that the foreign matter bump causes due to the impact of wear-resistant block in the ball dish breeze breaks, breaks away from, and the while has also formed " material dnockout ".In addition in the design and installation of the outside of knife bar protective sleeve, can prevent neck effectively because of the defective that attenuates of wearing and tearing unprotect, compared with similar products, prolong about 3 months work-ing life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of figure.
Embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present invention is elaborated.
As shown in Figure 1 and Figure 2, the integrated high abrasion revolving scraper of the utility model novel mosaic, comprise revolving scraper body 1, cutter head 3, it is characterized in that the embedded polylith wear-resistant block 3 that is equipped with at the cutter head place of scraper body 1, its described wear-resisting 3 can be 6～12; It is cambered surface that described wear-resistant block can be made into outside surface, and internal surface is the plane, is convenient to form whole attrition resistant working face, can make working face damage minimum result again when being subjected to the foreign matter bump, as shown in Figure 2.For improving the wear resisting property of its cutter head, wear-resistant block of the present utility model adopts highly purified silicate material to make.The hardness height of the wear-resistant block that this material is made (Vickers' hardness can reach 2000), shock resistance good (bending strength 390MPa).In order to prevent that neck from attenuating because of the wearing and tearing unprotect; the utility model is with protective sleeve 2 in the outside of revolving scraper body 1 close cutter head; the size of its protective sleeve can be by the height flexible design of material level on user's balling disk (-sc), general protective sleeve state length get final product at 100～150mm.
The utility model is simple in structure, and wear resistance is good, and protective sleeve can prevent the defective that neck attenuates because of the wearing and tearing unprotect effectively, long service life, and single cutter head life cycle surpasses 5 months,
