Abstract
The utility model discloses a kind of coal breaker erosion controls only to fly special-shaped shell, and the shell includes special-shaped liner and high-strength bolt；Special-shaped liner is designed as arc shell concave-convex type, and side special-shaped liner edge is equipped with bolt hole；High-strength bolt passes through bolt hole and symmetrical two pieces of special-shaped liners is fixed on rotor periphery, and two pieces of special-shaped liners surround shell；The special-shaped liner edge of shell two sides is welded on cavity liner plate, and flywheel, rotor are trapped among in shell.Crushing shell and sieve plate accessory service life in coal breaker can be improved in the utility model, and makes even particle size during coal crusher, prevents from splashing during coal crusher, causes to waste.
Description
Technical field
The utility model relates to coal breaker protective device field, in particular to a kind of coal breaker erosion control only flies special-shaped shell.
Background technique
The raw coal block size that coal mine acquires field acquisition is uneven, and coal cinder size needed for firepower electrical plant and household heating has centainly
Requirement, it is therefore desirable to the raw coal block of bulk is crushed, so that coal cinder being capable of full combustion.Existing coal breaker makes
With in the process, due to flywheel high speed rotation, causes the punching of raw coal block crushing process to generate coal cinder and splash, cause broken inside coal breaker
Slashings, sieve plate deformation, reduce the crushing shell in coal breaker and sieve plate accessory service life.Particle during influence coal crusher
Size is uneven, causes coal cinder burning uneven, influences the full combustion efficiency of coal cinder, wastes coal cinder utilization rate.
Utility model content
In order to solve the above technical problems, the purpose of the utility model is to provide a kind of coal breaker erosion controls only to fly special-shaped shell,
Specific technical solution is as follows:
A kind of coal breaker erosion control only flies special-shaped shell, and the shell includes special-shaped liner and high-strength bolt；
The special-shaped liner is designed as arc shell concave-convex type, and side special-shaped liner edge is equipped with bolt hole；
The high-strength bolt passes through bolt hole and symmetrical two pieces of special-shaped liners is fixed on rotor periphery, two pieces of special-shaped liners
Surround shell；
The special-shaped liner edge of the shell two sides is welded on cavity liner plate, and flywheel, rotor are trapped among in shell.
A kind of coal breaker erosion control, which stops, flies special-shaped shell, and preferred embodiment is uniform there are four the high-strength bolt is set
It is distributed in special-shaped liner edge.
A kind of coal breaker erosion control only flies special-shaped shell, and preferred embodiment is that the arc shell of the special-shaped liner is recessed
Convex is made of 1/4 arc plate of two panels.
A kind of coal breaker erosion control only flies special-shaped shell, and preferred embodiment is that the special-shaped liner uses fiber composite
Plate is made.
A kind of coal breaker erosion control stops the working principle of winged special-shaped shell: in use, two pieces of special-shaped liners are passed through high-strength spiral shell
Bolt is fixed on around the rotor of broken coal machine equipment, increases arcuate relief abnormal shape shell, is rushed during coal crusher for preventing
It hits and splashes, flywheel is caused to wear, and flywheel can be protected to increase preventing impact abrasion, protecting effect.
The utility model has the beneficial effects that shell is two pieces of arcuate relief special-shaped liners, shell rim is arranged to bolt hole
Hole prevents coal in use, two panels arcuate relief abnormal shape shell to be fastened on to the peritrochanteric of coal breaker by high-strength bolt
The effect of splashing is generated in block shattering process.Using fibrous composite, crushing shell, sieve plate can be made to reduce impact wear and prolonged
Its long service life, avoids wasting.Crushing shell and sieve plate accessory service life in coal breaker can be improved in the utility model, and
And make even particle size during coal crusher, it prevents from splashing during coal crusher, causes to waste.

Specific embodiment
A kind of coal breaker erosion control only flies special-shaped shell as shown in Figs 1-4, and the shell 7 includes special-shaped liner 4 and high-strength spiral shell
Bolt 5；
The special-shaped liner 4 is designed as arc shell concave-convex type, and side special-shaped liner edge 3 is equipped with bolt hole；
The high-strength bolt 5 passes through bolt hole and symmetrical two pieces of special-shaped liners 4 is fixed on 2 periphery of rotor, two pieces of abnormal shapes
Liner plate 4 surrounds shell 7；
4 edge of special-shaped liner of 7 two sides of shell is welded on cavity liner plate a8 and cavity liner plate b9, by flywheel 6, is turned
Son 2 is trapped among in shell 7.
The high-strength bolt 5 is evenly distributed at special-shaped liner edge 3 there are four setting.
The arc shell concave-convex type of the special-shaped liner 4 is made of 1/4 arc plate of two panels.
The special-shaped liner 4 is made of fiber composite plate.
A kind of coal breaker erosion control stops the working principle of winged special-shaped shell: in use, two pieces of special-shaped liners 4 are passed through high-strength spiral shell
Bolt 5 is fixed on around the rotor 2 of broken coal machine equipment 1, increases shell 7, is impacted and is splashed during coal crusher for preventing,
It causes flywheel 6 to wear, and flywheel 6 can be protected to increase preventing impact abrasion, protecting effect.
