Description

A kind of wear-out part and the rotor of disintegrating machine

Technical field

This utility model relates to the rotor of a kind of wear-out part and disintegrating machine, particularly relates to a kind of for high speed impact Shaping and the wear-out part of disintegrating apparatus and the rotor of disintegrating machine.

Background technology

Disintegrating machine is widely used in the industrial departments such as cement, chemical industry, electric power, metallurgy, and disintegrating machine mainly leans on Impact energy completes broken material operation, and during disintegrating machine work, driven by motor rotor makees high speed rotating, material Uniformly entering in broken machine cavity, at a high speed the tup of revolution impact, shears, tears material and cause material and crush, same Time, the action of gravity of material self makes material rush at support body Internal baffle, grating from the tup of high speed rotating, is more than The material detention of screen size continues the strike by hammer and grinding on sieve plate, until being crushed to required discharging Granularity, finally by sieve plate discharge machine outside.

The impact crusher used in the market, Fig. 1 show the structural representation of the rotor of existing disintegrating machine Figure, the rotor 10 of disintegrating machine is provided around three wear-out parts being connected by screw (not shown) with rotor 10 11, wear-out part 11 uses rich chromium cast iron and hard alloy to make, this material under lower-speed state (2000 turns / minute about), friction durability still may be used；But for the shaping of single crystal product article, need higher rotating speed (to be more than 4000 revs/min), the wear-out part of this material, service life is shorter, and manufacturing cost is high, use cost Greatly, therefore typically now company uses manganese steel plate to add wear resistance electrode built-up welding and use as wear-out part material, but makes The most relatively low with the life-span.

Therefore, it is necessary to design the rotor of a kind of new disintegrating machine.

Utility model content

The purpose of this utility model is to provide the structure of a kind of wear-out part improving rotor and material, raising rotor Physical life and be convenient for changing the wear-out part of wear-out part and the rotor of disintegrating machine.

This utility model provides a kind of wear-out part, comprising: shell and be plugged on enclosure and use pressure The nozzle that the type of making is made, the centre of this nozzle is provided with nozzle bore.

Wherein, described nozzle bore is coniform.

Wherein, described shell is cylindrical.

This utility model also provides for the rotor of a kind of disintegrating machine, rotor be provided around multiple wear-out part, wear-out part Shell be fixed on rotor.

Wherein, the plurality of wear-out part is evenly distributed on around rotor.

Wherein, described wear-out part has 3.

The rotor of this utility model disintegrating machine is by making the wear-out part of existing bulk into cylindric nozzle form Wear-out part, and the nozzle of wear-out part uses plug-in type to be connected with the shell of wear-out part, is convenient for changing nozzle, and sprays Mouth uses compressing mode to make, and can be designed to various sizes of nozzle bore, reaches optimal shaping effect Really.

Detailed description of the invention

This utility model discloses a kind of for high speed impact shaping with the rotor of the disintegrating machine of disintegrating apparatus, this rotor 20 be provided around multiple wear-out part 30, wear-out part 30 is cylindrical, and each wear-out part 30 includes and rotor 20 The shell 31 of contact and be plugged on the nozzle 32 within shell 31, wherein, shell 31 is cylindrical；Nozzle 32 Centre be provided with in cone shape nozzle bore 321.Described wear-out part 30 is provided with 3, is evenly distributed on rotor 20 Around.

Described nozzle 32 is formed by superhard silicon-carbon (SiC) compacting, and nozzle 32 can be dismantled and change, nozzle 32 to make simple, low price, service life long.Broken material puts in nozzle 32 and carries out grinding, due to Nozzle is that employing is compressing, and nozzle can be designed to various sizes of nozzle according to the granule size of material Hole, thus reach optimal shaping effect.

This utility model by making the wear-out part of cylindric nozzle form into by the wear-out part of existing bulk, and abrasion The nozzle of part uses plug-in type to be connected with the shell of wear-out part, is convenient for changing nozzle, and nozzle uses compressing Mode make, various sizes of nozzle bore can be designed to, reach optimal shaping effect.

Above specific embodiment of the utility model is described in detail, but content has been only this utility model wound The preferred embodiment made, it is impossible to be considered for limiting the practical range that this utility model is created.Fan Yiben is practical Equalization change and the improvement etc. that novel creation application range is made, all should still belong to patent of the present utility model and contain Within the scope of lid.
