Description

Vertical impact crusher
Technical Field
The utility model belongs to the technical field of the breaker manufacturing technology and specifically relates to a vertical impact crusher for broken building stones.
Background
A vertical impact crusher is novel high-efficiency crushing equipment in the industries of metallurgy, building materials and the like. High hardness materials such as crushed basalt, granite, marble, stone, limestone, clinker, slag, coke, coal and the like. The product has large granularity adjustment range, is fine and uniform, and is the first choice of highways, railways, airports, hydraulic engineering and the like which have higher requirements on stone shapes. The vertical impact crusher is also called vertical impact crushing, is novel high-efficiency crushing equipment in industries such as metallurgy, village construction and the like, and has the advantages of large crushing ratio, cubic particles of mine materials after crushing and the like. Small equipment volume, simple structure, large crushing ratio, low energy consumption, large production capacity, uniform product granularity and selective ore crushing function. The gap that current vertical counterattack breaker was used, has some dust to emerge through the breaker casing, because the lower part bearing department in the breaker adopts labyrinth seal, lime powder that the broken building stones produced for a long time can pile up around labyrinth seal, makes lime powder get into the bearing easily like this in, and accumulational high temperature lime powder can influence the heat dissipation of bearing moreover, reduces bearing life.
SUMMERY OF THE UTILITY MODEL
The utility model provides a problem to provide a vertical impact crusher to lime dust toward emitting, lime powder piles up the problem that reduces bearing life in labyrinth sealing portion when solving the broken building stones of current vertical impact crusher.
In order to solve the above problem, the utility model discloses a technical scheme is: the vertical impact crusher comprises a casing, wherein a feed inlet is formed in the top of the casing, a base is arranged at the bottom of the casing, a discharge outlet is formed in the base, a main shaft is arranged inside the casing, a belt pulley is arranged on the upper portion of the main shaft, the lower portion of the main shaft is connected with the base, a plurality of bearings are arranged between the lower portion of the main shaft and the base, a labyrinth sealing cover for protecting the bearings is arranged on the base, an upper rotor and a lower rotor are arranged on the main shaft, and a dust suppression plate is arranged between the lower rotor and the labyrinth sealing cover.
In the above technical solution, a more specific technical solution may also be: the dust suppression plate is vertically welded to the bottom of the lower rotor.
Further: a10 mm gap is kept between the dust suppression plate and the labyrinth seal cover.
Further: the dust suppression plate is five steel plates with the length of 500mm, the width of 100mm and the thickness of 10 mm.
Further: and a partition plate is arranged between the upper rotor and the lower rotor.
Further: the baffle is welded on the casing, the baffle with the contained angle between the casing is angle A, angle A is 60 degrees ~ 75 degrees.
Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has:
1. the dust suppression plate well inhibits the lime powder at the discharge port from upwelling to cause raised dust, a gap of 10mm is kept between the dust suppression plate and the labyrinth seal cover, the lime powder accumulated around the labyrinth seal cover can be cleaned in time, the influence of the dust on the bottom bearing is reduced, and the service life of the bearing is prolonged;
2. through being equipped with the baffle between upper rotor and lower part rotor to baffle and casing are 60 degrees ~ 75 degrees contained angles, can prevent effectively that the dust from surging upward from the next door and causing the raise dust.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
the vertical impact crusher as shown in figure 1 comprises a machine shell 1 with a feeding hole 1-1 at the top and a base 1-3 at the bottom, a discharging hole 1-2 is arranged on the base 1-3, a main shaft 2 is arranged in the machine shell 1, a belt pulley 2-1 is arranged at the upper part of the main shaft 2, the lower part of the main shaft 2 is connected with the base 1-3, a plurality of bearings 2-2 are arranged between the lower part of the main shaft 2 and the base 1-3, a labyrinth type sealing cover 2-2-1 for protecting the bearings 2-2 is arranged on the base 1-3, an upper rotor 2-3 and a lower rotor 2-4 are arranged on the main shaft 2, and a dust suppression plate 2-4-1 is arranged between the lower rotor 2-4 and the labyrinth type sealing cover 2-2-1; the dust suppression plate 2-4-1 is vertically welded at the bottom of the lower rotor 2-4; a gap of 10mm is kept between the dust suppression plate 2-4-1 and the labyrinth seal cover 2-2-1; the dust suppression plate 2-4-1 is five steel plates with the length of 500mm, the width of 100mm and the thickness of 10 mm; a partition plate 3 is arranged between the upper rotor 2-3 and the lower rotor 2-4; the partition board 3 is welded on the casing 1, and an included angle between the partition board 3 and the casing 1 is an angle a of 60-75 degrees, in this example, the angle a is 75 degrees.
When in use, the belt pulley 2-1 drives the upper rotor 2-3 and the lower rotor 2-4 on the main shaft 2 to rotate, stone is put in from the feed inlet 1-1, and is crushed by the upper rotor 2-3 and the lower rotor 2-4 and then is discharged from the discharge outlet 1-2; when the stone is crushed, the five dust suppression plates 2-4-1 and the lower rotor 2-4 rotate together at a high speed to form a downward pressure on the discharge port 1-2 so as to suppress the upward emission of dust; the lower rotor 2-4 drives the dust suppression plate 2-4-1 to rotate while rotating, so that lime powder accumulated around the labyrinth seal cover 2-2-1 at the bottom of the crusher is scraped, and the influence of dust on the bottom bearing 2-2 is reduced; in the crushing process, a little dust can also emerge upwards along the inner wall of the machine shell 1, a partition plate 3 with 75 degrees is arranged between the upper rotor 2-3 and the lower rotor 2-4, the dust can be effectively blocked and guided to the lower rotor 2-4, the dust is blown to the discharge port 1-2 by wind pressure generated by high-speed rotation of the five dust suppression plates 2-4-1, and through multiple improvement design, when an angle A between the partition plate 3 and the machine shell 1 is larger than 75 degrees, a very small amount of dust can emerge from the feed port 1-1, when the angle A is smaller than 60 degrees, dust is easy to accumulate at an included angle although no dust emerges from the feed port 1-1, and when the angle A is between 60 degrees and 75 degrees, no dust emerges from the feed port 1-1, and dust cannot accumulate at the included angle.
