Abstract

The utility model relates to a dustproof pulverizer. The dustproof pulverizer comprises a bearing (8), a shell (3), a central shaft (7) and a front pressing cover (4) and is characterized in that a first separation blade (5) is arranged at a part of the central shaft (7), which is close to the front pressing cover, and a second separation blade (6) is arranged at a part of the shell (3), which is close to the front pressing cover (4). As the dustproof pulverizer is provided with the first separation blade (5) and the second separation blade (6), dust cannot enter the inner part of a bearing cavity (9), so that the problems that balls in the bearing (8) are jammed and damaged and gets rusty, and the like are solved.

Description

A kind of anti-dust pulverizer

Technical field

The utility model relates to a kind of reducing mechanism, comprises belt, rear pressing cover, shell, bearing, central shaft, front gland and catch.

Background technology

Pulverizer is that large-sized solid material is crushed to the machinery that requires size.

According to pulverizer being divided into boulder crusher, pulverizer, micronizer by the size of particle or broken material processed.

The external force that puts on solid in crushing process has shearing, impacts, rolls, grinds four kinds.Shear and be mainly used in coarse crushing (fragmentation) and comminution process, be applicable to flexible or have the material of fiber and fragmentation or the comminution process of bulk material; Impact and be mainly used in comminution process, be suitable for the pulverizing of brittle material; Roll and be mainly used in high finess disintegrating (ultramicro grinding) operation, the material that is suitable for most of character carries out ultramicro grinding operation; Grinding is mainly used in ultramicro grinding or ultra-large type disintegrating apparatus, is suitable for the further comminution process after comminution process.

The bearing portion of pulverizer, due to often in dust atmosphere, is very easily subject to erosion and the pollution of dust.Dust enters after bearing cavity, can cause bearing ball tied, get rusty and damage.

Summary of the invention

This is in order to address the above problem, and the utility model comprises bearing, shell, central shaft and front gland; On described central shaft, near front gland place, be provided with the first catch; On described shell, near front gland place, be provided with the second catch, the first catch and the second catch radius are all less than shell radius.

Owing to being provided with the first catch between front gland and bearing, on shell, near front gland place, be provided with the second catch, and because this catch radius is less than shell radius, so leave gap between catch and shell, can not cause wearing and tearing because of vibrations friction.Owing to maintaining interval between two catch, so can not cause because of vibrations the wearing and tearing of catch.Meanwhile, owing to being provided with catch, dust cannot enter bearing inside cavity, solved bearing ball tied, get rusty and the problem such as damage.

In addition, because the material of catch is pottery, smooth surface, is difficult for absorption dust, thereby avoid forming, stops up.

Accompanying drawing explanation

Fig. 1 is the utility model longitudinal sectional view.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment is made to detailed description.

A kind of anti-dust pulverizer in Fig. 1, comprises bearing 8, shell 3, central shaft 7 and front gland 4.On described central shaft 7, near front gland 4 places, be provided with the first catch 5; On described shell 3, near front gland 4 places, be provided with the second catch 6, the first catch 5 and the second catch 6 radiuses are all less than shell 3 radiuses.

Because the radius of the first catch 5 and the second catch 6 is all less than the radius of shell 3, so have gap between the first catch 5, the second catch 6 and shell 3, the first catch 5, the second catch 6 can not cause self wearing and tearing because of vibrations friction.Because the first catch 5,6 of the second catch maintain interval, so can not cause because of vibrations the wearing and tearing of catch.Meanwhile, owing to being provided with the first catch 5 and the second catch 6, dust cannot enter bearing cavity 9 inside, thus solved the ball at bearing 8 places tied, get rusty and the problem such as damage.

As further improvement, the first catch 5, the second catch 6 can change ceramic material catch into.Due to the smooth surface of ceramic material own, be easy to adhere to dust, so can effectively adhere to dust, prevent that dust from entering bearing cavity 9 inside.

Claims

1. an anti-dust pulverizer, comprises bearing (8), shell (3), and central shaft (7) and front gland (4), is characterized in that: described central shaft (7) is upper locates to be provided with the first catch (5) near front gland (4); Described shell (3) is upper locates to be provided with the second catch (6) near front gland (4).

2. a kind of anti-dust pulverizer according to claim 1, is characterized in that: described the first catch (5) and described the second catch (6) are ceramic material catch.
