Description

The impeller cyclone dust collectors

Technical field:

What the present invention relates to is a kind of cyclone dust collectors with rotary blade, and particularly a kind of impeller cyclone dust collectors that are suitable for removing solid particle size≤10 μ m belong to the fluid machinery technical field.

Background technology:

General in the market cyclone dust collectors, dusty gas is under the effect of the air-introduced machine of deduster outside, tangentially enter deduster from the import department on deduster top, in deduster, the circle tube inner wall of deduster forces dusty gas work spiral circular motion from top to bottom, under action of centrifugal force, small solid grit is thrown toward barrel and is captured, separated gas is then middle from bottom to top at cylinder, through the core pipe of deduster exit, flow out by the pipeline that is connected with air-introduced machine from the top.The cyclone dust collectors that have also have the deflector by being installed in the deduster to make air-flow produce circular motion.Above-mentioned cyclone dust collectors have a common ground, i.e. the rotation of air-flow is the effect owing to how much walls, and centrifugal force is also not very big, so just powerless less than the grit of 10 μ m for solid particle size.If improve separating property by the speed that improves inlet air flow, then can increase the flow losses of whole system, it directly influences and is, causes energy consumption to increase.。

In prior art, the patent No. is 91231398.6, name is called the patent of " active cyclone dust collectors ", and it is at " the air draft mouth of pipe place on housing top is installed with a fan rotor ", " this structure makes full use of the rotary speed that pre-spin that rotor produces dirt improves dust-contained airflow in the deduster ", " with the raising efficiency of dust collection, cut down the consumption of energy ".Because fan rotor is installed in the air draft mouth of pipe, so in impeller, obtain the air-flow of strong rotary speed, can only discharge the deduster cylindrical shell along impeller, even rotary speed is big again, also be difficult to improve the rotary speed of the dust-contained airflow in the deduster cylindrical shell; The motor that drives fan rotor simultaneously is positioned at the deduster cylindrical shell, and when the temperature of dust-contained airflow surpasses 100 ℃, then this motor just is easy to burn.

Summary of the invention:

For deficiency and the defective that overcomes prior art, under the prerequisite that does not increase energy consumption, improve the performance of cyclone dust collectors.The present invention has constructed the impeller cyclone dust collectors that can separate littler solid particle size.Two parts dedusters in the original cyclone dust collectors system and air-introduced machine are combined.The centrifugal impeller that is about to air-introduced machine is put into deduster, and centrifugal impeller becomes the import of deduster, and deduster then becomes the shell of centrifugal impeller.When the impeller cyclone dust collectors are worked, dust-contained airflow enters deduster through centrifugal impeller, because the effect of centrifugal impeller, it is much bigger more than the centrifugal force that obtains from circular wall usually to enter centrifugal force that the ash-laden gas of deduster obtains, so separating effect will significantly improve.Owing to saved the spiral case of air-introduced machine, avoided the impact of air-flow simultaneously, also reduced the noise of system the spiral case wall.

The present invention is mainly simplified by simplified, core tube stent outward, air inlet pipe, motor, electric machine support, inlet box, afflux circle, impeller, escape pipe, core, dust hopper, unload the dirt pipe and form.Impeller is a receded disk impeller, directly is connected with motor, and motor is connected on the inlet box with screw by support.Inlet box is that a cylinder is simplified, and the side is connecting air inlet pipe, is connected with simplified, afflux circle outward below by screw.Core is simplified also to be that a cylinder is simplified, is equidistantly welding four core tube stents on its outer surface, and the core tube stent welds together with outer cylinder body again, and escape pipe is also being welded in its side simultaneously, and the other end and the outer cylinder body of escape pipe weld together.The following of outer cylinder body welding dust hopper and unloading the dirt pipe.

The present invention can make the particle diameter≤10 μ m of separated solia particle, has improved the efficiency of dust collection of deduster, has reduced the noise of dust pelletizing system, has very important significance for environmental protection, has obvious social and economic benefit.

The drawings and the specific embodiments:

Fig. 1 is the structure principle chart of impeller cyclone dust collectors

Among the figure 1 be outer simplified, the 2nd, core tube stent, the 3rd, air inlet pipe, the 4th, motor, the 5th, electric machine support, the 6th, inlet box, the 7th, afflux circle, the 8th, impeller, the 9th, escape pipe, the 10th, core cylindrical shell, the 11st, dust hopper, the 12nd unloads the dirt pipe.

Below in conjunction with accompanying drawing concrete enforcement of the present invention is further described:

By shown in Figure 1, the impeller cyclone dust collectors comprise that outer simplified 1, core tube stent 2, air inlet pipe 3, motor 4, electric machine support 5, inlet box 6, afflux circle 7, impeller 8, escape pipe 9, core are simplified 10, dust hopper 11, unload dirt pipe 12.Impeller 8 is receded disk impellers, directly is connected with motor 4, and motor 4 is connected on the inlet box 6 by support 5 usefulness screws.Inlet box 6 is that a cylinder is simplified, and the side is connecting air inlet pipe 3, is connected with outer simplified 1, afflux circle 7 below by screw.Core simplified 10 also is a cylindrical tube, is equidistantly welding four core tube stents 2 on its outer surface, and core tube stent 2 welds together with outer simplified 1 again, and escape pipe 9 is also being welded in its side simultaneously, and the other end of escape pipe 9 and outer cylinder body 1 weld together.The following of outer cylinder body 1 welding dust hopper 11 and unloading dirt pipe 12.

During the work of impeller cyclone dust collectors, dusty gas is inhaled into air inlet pipe 3, through inlet box 6 and afflux circle 7, enter the impeller 8 that is rotating, dusty gas in impeller 8 by centrifugal force toward radially throwing away, the annular space between outer cylinder body 1 and core simplified 10 is made spiral circular motion from top to bottom, solia particle is with outer simplified 1 wall bump and be captured, fall into dust hopper 11, can discharge by unloading dirt pipe 12.Separated air-flow is then turned back upwards, enters core cylindrical shell 10, flows out through escape pipe 9.Because the effect of centrifugal impeller, the centrifugal force that dusty gas is subjected to is more much bigger than common deduster, makes separating effect better, and the particle diameter of separated solia particle≤10 μ m has improved the efficiency of dust collection of deduster.Also reduced the noise of dust pelletizing system simultaneously.
