Abstract
The utility model discloses an outer drum expansion device for a spiral drum slagging machine, and relates to the technical field of slagging machines. The device comprises an inner drum and an outer drum, wherein a plugging structure is arranged between the inner drum and the outer drum. The device is characterized in that the plugging structure is an expansion joint which is connected with the inner drum and the outer drum. Because the expansion joint is arranged between the inner drum and the outer drum, the expansion amount of the outer drum can be compensated automatically by the expansion joint on the premise that the expansion coefficients of the inner drum and the outer drum are different, so that a water leakage phenomenon caused by tearing an end seal plate is prevented; and the reliability of equipment operation is improved.
Description
Technical field
The utility model relates to the slag extractor technical field, especially a kind of helix drum slag extractor urceolus expansion gear.
Background technology
Boiler is used widely in a lot of industries as a kind of energy conversion, and the cinder that boiler combustion produces needs to discharge, and need clear up timely and transport.The deslagging temperature of boiler is about 950 ℃; The extreme temperatures transportation is very inconvenient; And bring very big hidden danger for site environment and production, and need this moment to use helix drum slag extractor heat exchange structure to lower the temperature to slag, slag is dropped to below 100 ℃; On-the-spot environment can be improved, more means of transportation can be adopted again.
Like Fig. 2; Traditional helix drum slag extractor heat exchange structure comprises swing roller; Be cooling water between the inner core of swing roller and the urceolus, solid welding has the spirally-guided heat exchanging piece on inner tube wall, and slag is realized heat exchange through spirally-guided heat exchanging piece and inner core with the heat transferred cooling water like this.Because the slag temperature in the inner core is about 950 ℃; Connect with shrouding 1 between the inner/outer tube, inner core 3 temperature are much larger than urceolus 2 temperature, and the coefficient of expansion between the inner/outer tube is different; Cause the end shrouding of helix drum slag extractor being torn apart, cause leaking in the output section.
The utility model content
The purpose of the utility model is to provide a kind of helix drum slag extractor urceolus expansion gear, and it can compensate the urceolus swell increment automatically under the different prerequisite of the coefficient of expansion between the inner/outer tube, prevents that the end shrouding from tearing apart, and causes leaking.
The technical scheme that its technical problem of the utility model solution is taked is: helix drum slag extractor urceolus expansion gear, comprise inner core and urceolus, and between the two, be provided with plugging structure, it is characterized in that described plugging structure is for connecting the expansion joint of inner core and urceolus.
Described expansion joint is the hook-shaped of evagination.
Compared with prior art; The helix drum slag extractor urceolus expansion gear of the utility model has following outstanding beneficial effect: owing to be provided with expansion joint between inner core and the urceolus; Under the different prerequisite of the coefficient of expansion between the inner/outer tube, lean on expansion joint can compensate the urceolus swell increment automatically, prevent that the end shrouding from tearing apart; Cause leaking, improved the equipment reliability of operation.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the prior art constructions sketch map;
Among the figure: 1 shrouding, 2 urceolus, 3 inner cores, 11 expansion joints.
The specific embodiment
Do further to describe below in conjunction with 2 pairs of the utility model of Figure of description 1 and accompanying drawing:
The helix drum slag extractor urceolus expansion gear of the utility model comprises the swing roller of being made up of urceolus 2 and inner core 3, is cooling water between inner core 3 and the urceolus 2.
Between inner core 3 and urceolus 2, be provided with plugging structure, described plugging structure is for connecting the expansion joint 11 of inner core 3 and urceolus 2.Described expansion joint 11 is the hook-shaped of evagination.
Expansion joint 11 can also have other structure, as long as have expanded by heating, the structure that can compensate the urceolus swell increment automatically all can, ripple struction for example.
The above; Some principles of the utility model just explain through diagrams; This specification be not be to the utility model be confined to shown in described concrete structure and the scope of application; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
Except that the said technical characterictic of specification, all the other technical characterictics are those skilled in the art's known technology.
