Abstract
The utility model relates to a kind of air outlet abrasion-proof structure of cement powder concentrator, comprises the passage being connected to discharge pipe end, and the end of discharge pipe is connected short tube, and the wall thickness of short tube is greater than the wall thickness of discharge pipe, and the outer wall of short tube flushes with the outer wall of discharge pipe; The inwall of short tube is fixed with wear-resistant sleeve, the oriented discharge pipe end of one end band of wear-resistant sleeve stretches out and the flange of outwards turnover, flange abuts the inwall of discharge pipe, the other end of wear-resistant sleeve stretch out short tube end face and and with installing annular space between the adapter sleeve that is connected of short tube end face, spiral connection passage in described installation annular space.The utility model installs the high wear-resistant sleeve of wearability in the air outlet of discharge pipe by the short tube thickeied, and avoids itself and passage end directly to impact and causes heavy wear; Passage is connected by spiral between thickening ring and the thinning ring of adapter sleeve, and it is easy and simple to handle, connects reliable; Compare the direct-connected passage structure of traditional air outlet, greatly reduce wearing and tearing, extend the replacement cycle, reduce costs.
Description
Technical field
The utility model relates to field of cement production equipment, particularly the powder concentrator of manufacture of cement.
Background technology
In cement production process, commonly use powder concentrator.Air outlet be in powder concentrator production line cement powders enter warehouse for finished product must through part, run up with under the effect of system high negative pressure at powder concentrator, granule dust carries out impact wear to the passage of air outlet pipeline opening, cause heavy wear in the passage short time, need maintenance in time and change, otherwise causing security incident.In prior art, be connected to the passage that air outlet goes out and be directly installed on air outlet place, its wearability is not high, and replacement operation is comparatively difficult, if directly adopt the passage of abrasion-proof structure, then high cost.
Utility model content
The above-mentioned shortcoming that the applicant exists for the air outlet structure of existing powder concentrator, carries out studying and improving, provides a kind of air outlet abrasion-proof structure of cement powder concentrator, its have wearability high, change easy feature.
In order to solve the problem, the utility model adopts following scheme:
An air outlet abrasion-proof structure for cement powder concentrator, comprises the passage being connected to discharge pipe end, and the end of discharge pipe is connected short tube, and the wall thickness of short tube is greater than the wall thickness of discharge pipe, and the outer wall of short tube flushes with the outer wall of discharge pipe; The inwall of short tube is fixed with wear-resistant sleeve, the oriented discharge pipe end of one end band of wear-resistant sleeve stretches out and the flange of outwards turnover, flange abuts the inwall of discharge pipe, the other end of wear-resistant sleeve stretch out short tube end face and and with installing annular space between the adapter sleeve that is connected of short tube end face, spiral connection passage in described installation annular space.
Further improvement as technique scheme:
The outer wall of adapter sleeve flushes with the outer wall of short tube, and the end of adapter sleeve is with thinning ring, and thinning endless belt has internal thread, and the end of passage is with thickening ring, and thickening ring is with the external screw thread coordinated with thinning ring.
The outer wall end of described adapter sleeve welds with the outer wall end of short tube, and the inwall end of short tube welds with wear-resistant sleeve, and the flange of wear-resistant sleeve welds with the inwall end of discharge pipe.
Technique effect of the present utility model is:
Structure of the present utility model is simple, reasonable in design; Air outlet in discharge pipe installs the high wear-resistant sleeve of wearability by the short tube thickeied, and avoids itself and passage end directly to impact and causes heavy wear; Passage is connected by spiral between thickening ring and the thinning ring of adapter sleeve, and it is easy and simple to handle, connects reliable; The utility model compares the direct-connected passage structure of traditional air outlet, greatly reduces wearing and tearing, extends the replacement cycle, reduces costs.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the air outlet abrasion-proof structure of the cement powder concentrator of the present embodiment, comprises the passage 5 being connected to discharge pipe 1 end, and the end of discharge pipe 1 is connected short tube 2, the wall thickness of short tube 2 is greater than the wall thickness of discharge pipe 1, and the outer wall of short tube 2 flushes with the outer wall of discharge pipe 1; The inwall of short tube 2 is fixed with wear-resistant sleeve 3, one end band oriented discharge pipe 1 end of wear-resistant sleeve 3 stretches out and the flange 31 of outwards turnover, flange 31 abuts the inwall of discharge pipe 1, the other end of wear-resistant sleeve 3 stretch out short tube 2 end face and and with installing annular space between the adapter sleeve 4 that is connected of short tube 2 end face, spiral connection passage 5 in annular space is installed.
As shown in Figure 2, the outer wall of adapter sleeve 4 flushes with the outer wall of short tube 2, and the end of adapter sleeve is with thinning ring 41, and thinning ring 41 is with internal thread, and the end of passage 5 is with thickening ring 51, and thickening ring 51 is with the external screw thread coordinated with thinning ring 41.
As shown in Figure 2, the outer wall end of adapter sleeve 4 welds with the outer wall end of short tube 2, and the inwall end of short tube 2 welds with wear-resistant sleeve 3, and the flange 31 of wear-resistant sleeve 3 welds with the inwall end of discharge pipe 1.
Structure of the present utility model is simple, reasonable in design; Air outlet in discharge pipe installs the high wear-resistant sleeve of wearability by the short tube thickeied, and avoids itself and passage end directly to impact and causes heavy wear; Passage is connected by spiral between thickening ring and the thinning ring of adapter sleeve, and it is easy and simple to handle, connects reliable; The utility model compares the direct-connected passage structure of traditional air outlet, greatly reduces wearing and tearing, extends the replacement cycle, reduces costs.
Above illustrated embodiment is better embodiment of the present utility model, only be used for conveniently the utility model being described, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristic, utilize the utility model disclose the Equivalent embodiments changing or modify in the done local of technology contents, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
