Abstract
The utility model relates to a kind of coal nozzle, comprises housing, blade and mozzle; Described blade and mozzle are equipped with in housing; Described mozzle is arranged on the middle part of housing; Described blade centered by mozzle, and is disposed in an evenly spaced relation in mozzle outside in one week around mozzle, and blade is fixedly connected with mozzle; Described blade extends from mozzle to housing.The utility model can make mixing of wind and coal dust, and fine mist can be become to spray, thus make coal dust even Thorough combustion in combustion chamber, the length of flame is easily controlled, and improves the efficiency of combustion of coal dust, reduces production cost.
Description
Technical field
The utility model relates to coal dries industry device, particularly relates to a kind of coal nozzle.
Background technology
At present, drying coal nozzle in industry at coal is the wind and the mixed mixture of coal dust sent by blower fan, the equipment of combustion chamber is sent at a high speed after carrying out secondary mixing, after in combustion chamber, coal dust carries out Thorough combustion, hot-air is sent into drying plant as in Drying by quirk, material is dried again.There is following defect in existing coal nozzle: the huge and complex structure of the equipment of coal nozzle, takes up room large, and cost is high to be caused and once invest comparatively large, and installs difficulty; The mixed effect of wind and coal dust is poor, normal one-tenth strand ejection in combustion chamber, coal dust is slow in the speed of combustion chamber combustion, the length of flame is longer, even flame can arrive quirk and Drying combustion, and the efficiency of combustion of coal dust is low, part of fuel does not have enough time to burn and just takes away with the wind, wastes larger.
Summary of the invention
For the defect of prior art, the utility model proposes a kind of coal nozzle, simple for structure, take up room little, small investment is easy for installation, and the secondary good mixing effect of wind and coal dust can become fine mist to spray; Coal dust in combustion chamber combustion evenly fully, the length of flame easily controls, and reduces production cost.
For achieving the above object, the utility model proposes a kind of coal nozzle, comprise housing, blade and mozzle; Described blade and mozzle are equipped with in housing; Described mozzle is arranged on the middle part of housing; Described blade centered by mozzle, and is disposed in an evenly spaced relation in mozzle outside in one week around mozzle, and blade is fixedly connected with mozzle; Described blade extends from mozzle to housing.
Described housing comprises centrum and hypocentrum, and described upper centrum cooperatively interacts with the bottom surface of hypocentrum and is fixedly connected with.
Described mozzle is conical flow guiding pipe.
Described blade is four helical blades, and one end of helical blade is fixedly connected with mozzle.
Beneficial effect
The utility model, by the housing that arranges, mozzle and blade, makes mixing of wind and coal dust, fine mist can be become to spray, thus make coal dust even Thorough combustion in combustion chamber, the length of flame is easily controlled, and improves the efficiency of combustion of coal dust, reduces production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 of the present utility modelly looks up structural representation.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in the figure, a kind of coal nozzle of the utility model, comprises housing, blade and mozzle; Housing comprises centrum and hypocentrum, upper centrum and hypocentrum are hollow and all adopt the stainless steel of heat-resistant antifriction, two bottom surfaces of upper centrum and hypocentrum cooperatively interact and are fixed and welded together, mozzle is the mozzle being arranged on the taper of casing center along the axis of housing, and mozzle is fixed and welded together by support and housing.Blade and mozzle all adopt the stainless steel of heat-resistant antifriction.Blade centered by mozzle, and is disposed in an evenly spaced relation in mozzle outside in one week around mozzle, and blade and mozzle are fixed and welded together; Blade is four helical blades, and helical blade is prior art, and blade integral is S type helically, and one end of helical blade is welded with mozzle, and the other end of blade extends from mozzle to housing, and blade and mozzle cooperation are welded in housing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
