Abstract

The utility model relates to a crushing treating apparatus for wasted materials, comprising an outer shell which is provided with a feed inlet. A crushing knife roll which is driven to rotate by a driving mechanism penetrates into the outer shell. The utility model is characterized in that the knife roll is a circular drum body which is provided with a plurality of concave fixed slots; each of the concave fixed slots is respectively fixed with a fixed knife body which is provided with a convexly extending knife edge; all fixed knife bodies rotate synchronously with the circular drum body and cooperate with a knife plate which is arranged on rotary cutting port positions at the circumference of the circular drum body to crushing wasted materials; sawtoothed knife edges are arranged on the knife plate with intervals. After wasted materials are fed in through the feed inlet, the wasted materials are brought to the knife plate through the rotation of the convexly extending knife edges on the rotating drum body, then the wasted materials are cut and crushed through the staggered cutting action of the sawtoothed knife edge on the knife plate and the cutting edges of the knife bodies, and then the wasted materials are discharged through a sieve plate which is arranged on the lower part of the outer shell.

Description

A kind of discarded object processing equipment for pulverizing

The utility model relates to a kind of breaker, particularly a kind of discarded object processing equipment for pulverizing.

Existing waste treatment apparatus as shown in Figure 1, in fixing shell body, be movably set with two relatively turnable rotating shafts 2, in each rotating shaft 2, respectively be arranged with some disc reamers 1, each disc reamer circumferential spaced apart is provided with 2 to 3 edges of a knife 11, each dish type reamer distributes and along its certain angle that circumferentially staggers along axially string is folded separately, when two reamer groups are rotated relatively, edge of a knife is then by wide gradually narrow staggered variation on it, when discarded object places between the two reamer groups, then twisted the body that is cut into small pieces by the staggered edge of a knife.To reach reduced volume, to reduce the processing intent that takes up space, is convenient to reclaim, be convenient to compress landfill or burning.The shortcoming of this breaker is:

First, owing in each rotating shaft, be equipped with several disc reamers, the edge of a knife as a certain reamer damages, and then needs to change whole reamer, and, reamer in the middle of every replacing once, all dish type reamers will be taken off from axle one by one, and then load onto one by one, not only caused the waste of material, and, make the repair and replacement effort time-consuming.

Second, because two reamer groups are staggered incision rotation vertically when work, therefore, do not have any space between cutter piece and the cutter piece and have only very little axle side running clearance, when being entrained with object really up to the mark in the thing, then easily cause the stuck of reamer if be broken, and, in case stuck, then be difficult to cleaning and reject the mounting board thing.

The 3rd, because of the reamer group is the disk reamer string of thinner thickness and constitutes, and the intensity of discoid reamer is relatively poor, so the easy damage and crack of its edge of a knife.

The 4th, because the dish type reamer is better from inside to outside, your material is made, so the cost height, waste is big.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of prior art, and provide that a kind of crushing effect is good, easy to maintenance, long service life, cost is low and be difficult for stuck discarded object processing equipment for pulverizing.

The purpose of this utility model is to realize by following technical scheme:

The utility model has a shell body, one charge door is arranged on shell body, be equipped with the rotating shaft that turns by driving mechanism in the shell body, be arranged with broken reamer in the rotating shaft, it is characterized in that: broken reamer is one to offer the circular drum body of some indent holddown grooves, in each indent holddown groove, all be fixed with one and have the fixed cutter body that protrudes out cutting edge, each cutter hub rotates synchronously with barrel and acts on mutually with the knife plate that is blocked in its all side and changes the entry place and with the discarded object fragmentation, at the bottom week side ladle cover one lonely tabular sieve plate that cutter rolls.The spaced apart zigzag edge of a knife that is provided with on the knife plate, after discarded object is by material mouthful adding, evagination cutting edge on the cylinder that then is rotated changes and brings to the knife plate place, by the staggered shear action of cutting edge of the zigzag edge of a knife on the knife plate and cutter hub with the discarded object cutting and crushing, after its underpart sieve plate leak down.

Therefore remarkable result of the present utility model is as follows:

First, because each cutter hub is to be fixed on separately by screw in each indent holddown groove of cylinder, make and form the structure that does not contact and leave enough spaces of passing through for broken piece between each cutter hub, so, the utmost point is convenient to the maintain and replace after cutter hub damages, and also can not make hobboing cutter stuck because of hard object is arranged in the discarded object.

The second, because each cutter hub is the good block of intensity, so cutter hub is not fragile and have long service life.

The 3rd, sieve plate add if broken thing size than uniformity, the post-processed of being more convenient for.

The 4th, owing to setting up of knife plate, the quantity that cutter is rolled is reduced to one by two, has not only reduced taking up space, and has also reduced weight, and has made designs simplification.

The 5th, both have fragmentation because the cutting edge of the cutter hub of evagination and cylinder periphery are provided with at an angle and have formed, have the commentaries on classics band effect of scoop again, therefore, slightly the discarded object of bulk can be repeatedly by commentaries on classics bring to the knife plate place carry out repeatedly broken, so can reach good crushing effect.
