Description

A kind of polishing dust gathering arrester

Technical field

The utility model belongs to field of mechanical technique, more particularly to polishing purifying and dedusting device.

Background technique

Polishing machine can generate many flue dust in use, not only pollute the environment, but also directly affect operation The health of personnel, especially some metalwork products in generated flue dust such as long-term suction body, will cause various diseases Disease.Dust gathering arrester is a kind of device for controlling dust-contained airflow, collecting flue dust, it is the important component in Partial dust removal system, Dust gathering arrester is used primarily at the dirt source for pipe network system of gathering dust, the prior art due to being gathered dust mode using centralization, pipe network system compared with Long, the kinetic equation loss of system is big, and dirt source is in the front end for pipe network system of gathering dust, and dust dynamics weakens, and dust removing effects are undesirable. Using this polishing dust gathering arrester, meet aerology principle, the air inlet wind speed at dirt source can be improved moment, can effectively enhance flue dust Collection dynamics.

Utility model content

The purpose of the utility model is to overcome the defects of the prior art, provide a kind of polishing dust gathering arrester, realize throwing Flue dust is effectively collected in photoreduction process, has the characteristics that structure is simple and environmentally-friendly, energy consumption is low.

The utility model is realized in this way: a kind of polishing dust gathering arrester comprising:

One inside is exhaust column, connecting tube, dust collecting opening, the dust collecting opening baffle of cavity, is divided on the side wall of the exhaust column Several air inlets are not offered, and the air inlet can set quantity according to actual use demand, effectively improve service efficiency.

It further, further include dust collecting opening, described to be rectangle horn mouth, outer imperial palace is small, during collecting flue dust, The air-flow contraction small by outer imperial palace, can generate higher wind speed, form more preferable flue dust collecting effect, and can effectively prevent flue dust It flies upward.

Further, the connecting tube is arc connecting tube, and cross sectional shape is rectangle, and there are two types of significant for this structure Feature: first is that rectangular cross-sectional, be more advantageous to than circular configuration the metallic particles flown upward when collecting polishing product, the grains of sand and Flue dust；Second is that dust collecting opening and exhaust column are chained up with certain radian, more meet fluid engineering, keeps flue dust more conducively suitable Channel flowing, reduce resistance, energy consumption is effectively reduced.

Further, the dust collecting opening top be equipped with can be rotated and dismountable block plate, significantly more efficient promotion dust collecting effect, The safety of operator is improved simultaneously.

Further, the exhaust column, connecting tube, dust collecting opening are connected and fixed by modes such as screw or welding.

Beneficial effect provided by the utility model is:

Offer several air inlets on the side wall of the exhaust column respectively, the dust collecting opening be rectangle it is horn-like, it is outer big It is interior small, it is connect by arc connecting tube with exhaust column, communicates dust collecting opening with exhaust column, when dusty gas passes through horn-like dust The collection of mouth, when connecting pipeline section by arc, speed can increase moment, will form negative pressuren zone near swiftly flowing gas, To generate powerful adsorption capacity, effectively by flue dust collecting, flue dust is made to fully enter exhaust column, can effectively prevent flue dust and fly upward, The dust gathering arrester pressure loss is small, and dust collecting effect is good, meanwhile, the spy that the utility model also has structure simple and environmentally-friendly and energy consumption is low Point.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, can also be obtained according to these attached drawings other attached drawings.
