Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, labelling is as follows: ash inlet tube 1, ash inlet 2, suction flange 3, cement output tank 4, ash hole 5, outlet(discharge) flange 6, steel plate 7.
Detailed description of the invention
This utility model is made up of ash inlet tube 1, cement output tank 4, suction flange 3, outlet(discharge) flange 6.
Showing in figure, one end of ash inlet tube 1 is ash inlet 2, and ash inlet 2 welds suction flange 3, and the other end steel plate 7 of ash inlet tube 1 blocks.
Figure shows, circular hole is had at the middle part of ash inlet tube 1, circular hole in the middle part of ash inlet tube 1 is positioned at ash inlet tube 1 body central side away from ash inlet 2, center of circular hole and distance is ash inlet tube 1 length the 3/4 of ash inlet 2, and the body of all the other 1/4 length of ash inlet tube 1 is the blind pipe body blocked.
Showing in figure, one end of cement output tank 4 is connected with circular hole circumference vertical welding, and the other end of cement output tank 4 is ash hole 5, and ash hole 5 welds outlet(discharge) flange 6.Ash inlet tube 1 and cement output tank 4 are to being welded into irregular " T-shaped " elbow structure, one end Plate Welding in the shorter tube road of the ash inlet tube 1 of irregular " T-shaped " elbow structure is shut, during use, dedusting ash must enter from the mouth of pipe in the long pipe road of the ash inlet tube 1 of irregular " T-shaped " elbow, flowed out by cement output tank 4 from the middle circle hole site connecting cement output tank 4, the function of this device could be realized.
Ash inlet 2 of the present utility model is connected with the ash conveying pipe flange at two ends, ash conveying pipe elbow respectively with suction flange and 3 outlet(discharge) flanges 6 of ash hole 5.
Ash inlet tube 1 of the present utility model and cement output tank 2 adopt thick-walled pipe, and the wall thickness of pipeline is greater than 10 millimeters, to ensure enough abrasion resistances and service life.
This utility model in use, only need to unclamp the loose flange of former ash conveying pipe elbow and take off, wear-resistant bend device of the present utility model being connected with former ash conveying pipe two ends loose flange, is achieved that the function of wear-resistant bend.The principle of wear-resistant bend device is to utilize " material dnockout ", namely there is the occluding member of 1/4 pipe range ash inlet tube 1 and cement output tank 4 junction, part dust enters and forms blocking in occluding member, the dust of all the other conveyings directly clashes into the dust of closure in ash inlet tube 1 and cement output tank 4 junction when turning, formed " material dnockout ", without clashing into the tube wall of elbow, it is greatly reduced the abrasion of elbow.
An embodiment of the present utility model is as follows:
Adopting ￠ 121 seamless steel pipe of wall thickness 12 millimeters, blanking makes the steel pipe 2 that length is 1.2 meters, 0.48 meter, in the 3/4 place perforate of long 1.2 meters of seamless steel pipes, and in long 0.48 meter of seamless steel pipe to being welded into irregular " T-shaped " head bending device.Short tube mouth one end Plate Welding in the length 1.2 mitron road of " T-shaped " head bending device is shut, and the long tube mouth in long 1.2 mitron roads and the mouth of pipe in long 0.48 mitron road respectively weld a flange, namely become a kind of ash conveying pipe wear-resistant bend device.
During use, only need to unclamp the loose flange of former ash conveying pipe elbow and take off elbow, the wear-resistant bend of new production being connected with former ash conveying pipe two ends loose flange, is achieved that the function of wear-resistant bend.
Wear-resisting ash conveying pipe Simple bended head device is that the principle utilizing " material dnockout " makes.When therefore using, dedusting ash must conform to the principle of simplicity easy head bending device length 1.2 mitron road the mouth of pipe enter, flow out from the mouth of pipe in 0.48 mitron road, the function of Simple wear-resistant ash conveying pipe head bending device could be realized.
The direct economic benefit of the present embodiment:
This utility model efficiently solves ironmaking cleaning shaft finished product elbow and uses abrasion to scrap too fast, and because a variety of causes can not in time at once affecting cleaner unit production problem.This utility model also has the advantages such as simple in construction, easy for installation, reliable operation.According to statistics, the use time of the present utility model can extend to about 3 months, many more than the 30-50 days use time of existing elbow.Simultaneously, wear-resistant bend about 120 changed by 1 year needs of iron-smelter cleaning shaft equipment, an existing wear-resisting ash conveying pipe elbow (￠ 121) is worth 850 yuan/, and this utility model only needs 150 yuan, and expense=120 of annual saving/year × (850 yuan/only-150 yuan/only)=8.4 ten thousand yuan.
