Abstract

The utility model discloses a pulverizer with a dust removal device. The pulverizer comprises a pulverizing bin, an induced draft fan, a delivery pipe and a hopper, wherein the pulverizing bin is connected with the hopper by virtue of the delivery pipe; the induced draft fan is arranged on the delivery pipe; a plurality of small cloth bags are arranged at an air opening of the hopper and are used for preventing ash dust produced by materials which are induced into the hopper through the induced draft fan from dispersing in the air; a large cloth bag is also arranged on the outer layer of the plurality of small cloth bags; and air holes formed in the large cloth bag are smaller than air holes formed in the small cloth bags. According to the structure, air quality of production department can be maintained and the health of workers can be protected.

Description

With the pulverizer of dust arrester

Technical field

The utility model relates to pulverizer, particularly the pulverizer with dust arrester.

Background technology

The class advanced composite material (ACM) that China is surging forward in recent years, refer to utilize polyethylene, polypropylene and polyvinyl chloride etc., replace common resin adhesive, with exceed the useless strings such as more than 35%-70% wood powder, bamboo powder, rice husk, stalk and be mixed into new wood materials, again through the plastic processings such as extruding, mold pressing, injection moulding, the sheet material of producing or section bar.Be mainly used in the industries such as building materials, furniture, logistics packaging.After being mixed by a certain percentage, plastics and wooden powder through the sheet material of hot extrusion molding, be referred to as to push wood-plastic composite panel.In the time producing wood-plastic products, need first by wood chip, bamboo bits mix according to certain ratio and order with other materials after waiting plant to pulverize again again, wood chip, bamboo bits after pulverizer is pulverized in discharge particle be less than the material content of 3 millimeters and account for the more than 50% of total displacement, former pulverizer of haveing been friends in the past is as shown in Figure of description 3, dust arrester is not installed, first material is after crushing bin 1 ' is pulverized, passing through air-introduced machine 3 ' is transported in hopper 4 ' by carrier pipe 2 ' again, due to the wind-force relation of air-introduced machine 3 ', tiny material particles will be discharged to workshop from the gas port 5 ' of hopper easily, so just caused is that workshop dust phenomenon is very serious, pollute the air of workshop, have a strong impact on workers ' health.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of dust arrester of shredder hopper, and this device can greatly improve working environment, effectively protects that workman's is healthy.

With the pulverizer of dust arrester; comprise crushing bin, air-introduced machine, carrier pipe, hopper; crushing bin is connected with hopper by carrier pipe; carrier pipe is provided with air-introduced machine; gas port place at hopper is provided with several beanbags; described some beanbag skins are also provided with a large cloth bag; pore on described large cloth bag is less than the pore on some beanbags; can effectively stop that the dust of running out of is dispersed into workshop from the pore of large cloth bag from beanbag, keep the air quality of workshop and protection workman's health.
