Abstract
The utility model discloses a spreader of a cement pre-decomposition system comprising a spreading case. The upper port of the spreading case is communicated with an ascending pipe; the spreading case has a lateral surface extension port communicated with a discharging pipe; an ash removing hole is arranged below the lateral surface extension port of the spreading case; a plurality of anchoring cramps are fixedly distributed on the inner wall of the spreading case; refractory materials are cast on the surface of the anchoring cramp; and the lower port of the spreading case is a hot air inlet which protrudes inwardly. The utility model has simple structure, long service cycle, low cost and good spreading effect, and is convenient to process.
Description
Technical field
The utility model relates to a kind of material-strewing device that is used for the cement precalcining system.
Background technology
In new type nonaqueous cement production line, in the precalcining system whirlwind tube at different levels increase in pipeline material-strewing device is installed all, the material that enters in tremie pipe the increase in pipeline is uniformly dispersed, help material and high-temperature flue gas reaches sufficient heat exchange, thereby progressively finish the preheating and the predecomposition reaction of material.In precalcining system, material-strewing device plays crucial effect to material dispersed.Eliminate on the one hand under the material impulsion and can and shed material, go deep into barrier air in the upcast on the other hand, following ascending gas is stopped after, around it, form one higher part air-flow that detours, help breaking up and hold in the palm and rise material.Because of material and gas temperature height, the material-strewing device of usefulness was the high temperature steel material in the past, the cost height, and work-ing life is short, replacing, maintenance difficult.
Summary of the invention
The purpose of this utility model provides a kind of cement precalcining system material-strewing device, and is not only simple in structure, easy to process, and life cycle is long, cost is low, spreading is effective.
The technical solution of the utility model is as follows:
Cement precalcining system material-strewing device includes the spreading case, the upper port of spreading case and upcast are connected, the spreading case has side extending port and tremie pipe to connect, the below of spreading case side extending port has ash removing opening, described spreading chamber interior wall stationary distribution has a plurality of anchoring dogs, described anchoring dog surface casting has refractory matter, and described spreading case lower port is hot air intake place and is inside overshooting shape.
As further improvement of the utility model, described anchoring dog is Y and V font.
As further improvement of the utility model, described hot air intake place outer side wall is provided with calcium silicate board with microporous.
As further improvement of the utility model, 0～90 ° of the medullary ray of described spreading case side extending port and the scope of described spreading case medullary ray angle
Adopted the utility model cement precalcining system material-strewing device, whole box body utilizes the Q235-A steel plate to be welded by general steel plate, and internal surface is welded with heat-resisting anchoring dog, and the cast refractory castable, increase high temperature resistant, corrosion-resistant, abrasion resistance properties, life cycle extends to 3～4 years.Mould material is worn when serious, but the teeming mould material.Manufacturing cost and use cost will reduce significantly.
