Abstract
A length-adjustable burner nozzle for a predecomposition furnace of a dry process cement kiln comprises a fixed nozzle pipe (1) and a movable nozzle pipe (2), wherein the fixed nozzle pipe (1) is arranged at a flange (3); the movable nozzle pipe (2) is inserted into the fixed nozzle pipe (1); the burner nozzle is characterized in that an adjustment bracket (4) is arranged on the fixed nozzle pipe (1); another adjustment bracket (5) is also arranged on the movable nozzle pipe (2); and the adjustment brackets (4 and 5) are mutually connected through a bolt (6). The external part of a burner at the nozzle pipes is designed into the two-section structure; for the two sections of nozzle pipes, the distance from a phase to the insertion is adjusted by the bolt so as to realize that the length of the nozzle is adjustable; therefore, the optimal burning point is convenient to find, the burning efficiency is improved, and the service life of the nozzle is prolonged. The burner nozzle has simple structure and is convenient to adjust and easy to realize.
Description
Technical field
The utility model relates to a kind of cement making equipment, the burner nozzle that especially a kind of dry-process cement rotary kiln predecomposition furnace is used, specifically a kind of length adjustable dry-process cement rotary kiln predecomposition furnace burner nozzle.
Background technology
At present, along with the aggravation of urbanization process, city and road construction need a large amount of cement, and therefore, cement industry has obtained develop rapidly.In order to adapt to the needs of cement output, want newly-built cement furnace on the one hand, other method also should improve output by the improvement to existing cement furnace.And cement furnace is the big power consumer, and the efficiency of combustion that improves stove is to realize the key of energy-saving and emission-reduction.The nozzle of the predecomposition furnace of existing dry-process cement rotary kiln is stationary structure, and the length of the rear nozzle that is in place can't be regulated, and this just brings very big inconvenience to design and installation, has deviation will influence combustion efficiency and service life slightly.
Summary of the invention
The purpose of this utility model is because the non-adjustable installation difficulty that causes of nozzle length is big at existing dry-process cement rotary kiln predecomposition furnace burner, require high, very difficult assurance reaches designing requirement, influence the problem in efficiency of combustion and service life, design a kind of length adjustable dry-process cement rotary kiln predecomposition furnace burner nozzle.
The technical solution of the utility model is:
A kind of length adjustable dry-process cement rotary kiln predecomposition furnace burner nozzle, comprise fixedly jet pipe 1 and movable spouts 2, fixedly jet pipe 1 is installed in flange 3, movable spouts 2 is inserted will be in fixing jet pipe 1, it is characterized in that described fixedly jet pipe 1 is provided with adjusting support 4, also be provided with an adjusting support 5 on the movable spouts 2, regulate between the support 4,5 continuous by bolt 6.
The insertion end inwall of described movable spouts 2 is horn-like structure.
The beneficial effects of the utility model:
The utility model becomes the two-segment type structure by the partial design with the nozzle position combustor external, thereby two joint jet pipes have been realized the adjustable of nozzle length to the distance of inserting mutually by the bolt adjustment, help seeking the best combustion point, improve efficiency of combustion, prolong the service life of nozzle.
The utility model is simple in structure, and is easy to adjust, is easy to realize.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of length adjustable dry-process cement rotary kiln predecomposition furnace burner nozzle, comprise fixedly jet pipe 1 and movable spouts 2, fixedly jet pipe 1 is installed in flange 3, movable spouts 2 is inserted will be in fixing jet pipe 1, described fixedly jet pipe 1 is provided with regulates support 4, also be provided with an adjusting support 5 on the movable spouts 2, regulate between the support 4,5 continuous by bolt 6.In order to realize movable spouts 2 and fixing seamlessly transitting of jet pipe 1 inner chamber, the insertion end inwall of movable spouts 2 can be designed to horn-like structure when specifically implementing.As shown in Figure 1.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
Claims (2)
1. length adjustable dry-process cement rotary kiln predecomposition furnace burner nozzle, comprise fixedly jet pipe (1) and movable spouts (2), fixedly jet pipe (1) is installed in flange (3), movable spouts (2) is inserted will be in fixing jet pipe (1), it is characterized in that described fixedly jet pipe (1) is provided with adjusting support (4), also be provided with an adjusting support (5) on the movable spouts (2), regulate between the support (4,5) continuous by bolt (6).
2. nozzle according to claim 1 is characterized in that the insertion end inwall of described movable spouts (2) is horn-like structure.
