Abstract

The inventive crushing device has at least one rotating shaft (1) on which ring-shaped collars (6) are arranged at intervals from each other. U-shaped rotor disc segments (2) are placed over said collars (6), crushing tools being supported on the periphery of these rotor disc segments. A rotor disc segment (2) supports at least one protruding extension (4) on the end of at least one limb of the U, said extension at least partially covering the surface of the shaft (1) in the intermediate area as far as the axially removed next rotor disc segment (2) and extending from the limb of the U in the axial direction of the shaft.

Description

The breaker that has at least one one rotating shaft

The present invention is described according to claim 1, and its content is a breaker, the broken relevant article of this breaker, especially aspect washing as using in waste discharge or the trashformation.

Cutter as rotating in this class crusher is so it can realize that broken function is owing to the periphery at it has toothed rotating ring (cut ring) to do relative rotatablely moving, and reaches shearing, tears and broken effect with this.Except other factors, mainly be to show part and the distance of its opposite face and the effect of the distance between the rotating ring side and realize owing to rotating ring protruding.

The size of the wearing and tearing of rotating ring or rotating ring secter pat is relevant with the material that is broken, owing to produced wearing and tearing, the big more then broken effect of the distance between the distance of rotating ring opposite face and the rotating ring side is more little.

In order to recover desired ability to work, need to change the parts and/or the reparation (problem proposes 1) that are worn.

When under special harsh conditions, working, in the surface that singly is not present in the axle between the rotating ring secter pat of wearing and tearing (problem proposes 2) as breaker.Up to the present, be (very expensive by using the axle that quenches! ) or with the spacing retainer avoiding wearing and tearing, or add the wlding material at the position that has been worn.But realize that back two kinds of measures are pretty troublesome, particularly all the more so when the spacing retainer that replacing is worn, also be adventurous and in the environment of chemical waste is arranged, weld.

In addition, rotary body and spacing retainer have also weakened the function (problem proposes 3) of scraper plate simultaneously because the static strength that wearing and tearing are produced weakens (broken danger is arranged).

Because stability and reliability to breaker have very high requirement, make this apparatus structure very heavy thus.Therefore caused downtime and required hoisting apparatus and the working measure that may need and cause its high price because of the quality requirement of rotary body at last when changing rotary body and/or spacing retainer consequently make the expense costliness.

In system's (this description discloses its content) that EP-A1-6.261 describes, the rotating ring secter pat of changing the cutter of broken usefulness under the situation of taking out or having U type cross section can not dismantled, simultaneously as at US-A-3,991, in 994 systems of being narrated, it can sufficiently reduce time and the expense of changing the rotating ring secter pat (problem proposes 1) that is worn, proposes 2 and 3 but still can not deal with problems.

The present invention is to self having proposed a task: promptly dealing with problems with reasonable prices proposes 2 and 3, has taken into account our the known solution to problem proposition 1 simultaneously again.This task is resolved by in the feature explained in claim 1 and it overall.In relevant claim feature, narrated the structure of useful further in-depth.

Because this breaker life-span is long, the model that is expected to be narrated disposes novel U type rotating ring secter pat with minimum expense and has an axle protection convex shoulder.This rotary body preferentially is used for having hydraulically powered breaker, and they withdraw from or install automatic stopping with reduce that rotary body breaks dangerous and can reduce because the wearing and tearing that produce when using extra heavy primary product by the measure that adapts as counter-rotating, opposite cutter.

Draw analogous conclusions, this rotary body can be in the same way used in other crusher (fast or at a slow speed), no matter all can use when they use which kind of type of drive (as hydraulic pressure, electric or explosive motor) and use the rotary body static or that rotate of how much quantity (as 1,2,3 or more).

On accompanying drawing, show the profile of annular lip and the gland rotating ring secter pat on it, and introduce the present invention in detail with form for example.

Graphic explanation:

Fig. 1: according to the technical situation of EP-B1-6.261 and

Fig. 2 to 4: at the planform of the improved rotating ring secter pat of the present invention.

The annular lip of arranging on axle 1, it becomes the axle that overall structure (Fig. 1-4) or (not shown) be enclosed within a hexahedron by general known mode and axle and goes up or be linked together by the profile of tooth engagement.Flange 2 width of its axial direction in practical structures is approximately 30-40mm.

Be with rotating ring secter pat 2 or 2a (Fig. 1 and 2) on flange 6, they connect as " pin-screw " unit by a pretension of (not shown) with well-known mode, and are bumped on cannelure on axle 1 or the 1a 3 or 3a.Cannelure 3a (Fig. 2) has widened at axial direction with respect to groove 3 (Fig. 1, technical situation) in the case, has added convex shoulder 4 at the end of U-shaped rotation secter pat 2a both side edges, and they have been protected most of surface to make and have not been worn.

According to the planform of Fig. 3, rotating ring secter pat 2b only is with a convex shoulder 4b, and convex shoulder 4b has covered the major part distance between two rotating ring secter pat 2b.Therefore during fabrication, on the surface of axle, need not process a groove.

Certainly, structure as shown in Figure 4 also can be removed (as the structure of Fig. 3 axis 1b) that groove is processed under the following situation, if promptly rotating ring secter pat 2C has convex shoulder 4c at two ends of U-shaped lateral margin, and each convex shoulder will be processed to such form, and the relative convex shoulder 4c of promptly adjacent rotary annular piece 2C covers the distance between two adjacent rotating ring secter pat 2c basically.

Fig. 3 shows the gap 5b between convex shoulder 4b and the adjacent rotating ring secter pat 2b, and the gap 5c between two convex shoulder 4c shown in Figure 4 equally can be made into so little, it is only risen can eliminate because influence that thermal change produced the or wittingly surface of axle is stayed a part and be uncovered, like this, can simplify manufacturing technology on the one hand, also can play inhibition and alleviate the dismantlement work amount on the other hand broken small pieces of material.

In the structure of Fig. 5, the recessed medial surface of rotating ring secter pat 2d has involute profile face 7, it with axle 1c surface on similar toothed surface 8 play a part to be coupled to each other.This structure is compared with the structure of the splined shaft that also can realize in principle or hexahedron axle and should because it has reduced the danger of breaking, have been alleviated workload of assembling and dismantling and the transmission that has improved power as first-selection.
