Abstract
The utility model discloses a kind of blast cap and blast pipe assembled device, relate to water-tube boiler parts.This blast cap and blast pipe assembled device, described blast cap is sheathed on described airduct, and blast cap is provided with the eye of wind, and described airduct comprises at least one lug; Be provided with annular groove in described blast cap, annular groove side is provided with the breach be communicated with annular groove, and the lug of described airduct enters annular groove from breach, with the clamping of annular groove phase after rotating.The utility model solves blast cap in the past and easily blows off and not easily detachable problem.
Description
Technical field
The utility model relates to water-tube boiler field of components, particularly relates to a kind of blast cap and blast pipe assembled device.
Background technology
Need in water-tube boiler to use blast cap and blast pipe assembled device to introduce in boiler by wind, under wind action, make coal produce boiling and burn.
The blast cap of current employing and blast pipe assembled device, if the eye of wind is stopped by cinder, wind direction can be made descending, thus blast cap is subject to buoyancy upwards, blast cap is easily blown off, fixes blast cap and airduct according to non-removable mode, then be not easy to change blast cap, and current blast cap adopts cast steel manufacture, and wearability and corrosion resistance are all poor, change comparatively frequent.
Utility model content
The purpose of this utility model is to propose a kind of blast cap and blast pipe assembled device, this blast cap and blast pipe assembled device can be made to realize the fixing blast cap being easy to dismantle, prevent blast cap from being blown off.
For reaching this object, the utility model by the following technical solutions:
A kind of blast cap and blast pipe assembled device, described blast cap is sheathed on described airduct, and blast cap is provided with the eye of wind, and described airduct comprises at least one lug; Be provided with annular groove in described blast cap, annular groove side is provided with the breach be communicated with annular groove, and the lug of described airduct enters annular groove from breach, with the clamping of annular groove phase after rotating.
Further, described blast cap is provided with the first inward flange and the second inward flange by openend successively towards blind end, forms described annular groove by the gap between the first inward flange and the second inward flange, and described breach is located on the first inward flange.
Further, two lateral extents of described annular groove are identical with the thickness of lug.
Further, described lug is two, and described breach is identical with described lug quantity.
Further, described blast cap adopts carborundum manufacture.
The beneficial effects of the utility model have:
The airduct that the utility model adopts is provided with lug, is provided with annular groove in blast cap, and annular groove side is provided with the breach be communicated with annular groove, and the lug of airduct enters annular groove from breach, with the clamping of annular groove phase after rotating, thus prevents blast cap from being blown off; Blast cap is turned to breach corresponding with lug position, namely detachably.
Accompanying drawing explanation
Fig. 1 is the structural representation of the blast cap that provides of the utility model embodiment and blast pipe assembled device;
Fig. 2 is 1/4th sectional views of the blast cap that the utility model embodiment provides;
Fig. 3 is the upward view of the blast cap that the utility model embodiment provides.
In figure, 1, blast cap; 2, airduct; 3, the eye of wind; 4, lug; 5, annular groove; 6, breach; 7, the first inward flange; 8, the second inward flange.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of blast cap and blast pipe assembled device, blast cap 1 is sheathed on described airduct 2, and blast cap 1 is provided with the eye of wind 3, and airduct 2 comprises at least one lug 4; Be provided with annular groove 5 in described blast cap 1, annular groove 5 side is provided with the breach 6 be communicated with annular groove 5, and the lug 4 of described airduct 2 enters annular groove 5 from breach 6, with the clamping of annular groove 5 phase after rotating, blast cap 1 can not be blown off.
Blast cap 1 is provided with the first inward flange 7 and the second inward flange 8 by openend successively towards blind end, and form described annular groove 5 by the gap between the first inward flange 7 and the second inward flange 8, breach 6 is located on the first inward flange 7.
Two lateral extents of annular groove 5 are identical with the thickness of lug 4, and lug 4 can be stuck in annular groove 5 closely.
Lug 4 is two, and breach 6 is identical with described lug 4 quantity.
Blast cap 1 adopts carborundum manufacture, makes blast cap 1 high temperature resistant, wear-resistant, corrosion-resistant, reduces the frequency changing blast cap 1.
When installing blast cap and the blast pipe assembled device of the present embodiment proposition, by breach 6 position of corresponding for the lug 4 of airduct 2 blast cap 1, make lug 4 through breach 6, then lug 4 enters in annular groove 5, rotate blast cap 1 or airduct 2, lug 4 and breach 6 are staggered, thus realize preventing blast cap from being blown off; During dismounting, blast cap 1 is rotated to breach 6 and lug 4 correspondence position, blast cap 1 is mentioned, just can realize dismounting.
Obviously, above-described embodiment of the present utility model is only used to clearly demonstrate the utility model example, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
