Abstract
The utility model belongs to the technical field of auxiliary equipment for a fluidized bed, and particularly relates to a bell jar type blast cap, aiming at solving the problem that the normal and continuous running of a boiler is influenced since the blast cap head of the existing blast cap is easy to fall off. The bell jar type blast cap has the technical scheme that the bell jar type blast cap consists of a blast cap head and a blast cap seat, wherein the lower end of the blast cap head is connected with the blast cap seat by an internally-embedded structure, and the blast cap head is provided with a plurality of wind eyelets. The bell jar type blast cap has the advantages that the bell jar type blast cap is low in cost, the blast cap head is hard to fall off, the stable running of the boiler is guaranteed, and the like.
Description
Technical field
The utility model belongs to fluid bed auxiliary equipment technical field, is specifically related to a kind of bell-jar blast cap.
Background technology
Blast cap commonly used is made up of blast cap head, inner sleeve, blast cap seat, its Apoplexy cap head and blast cap seat adopt detachable structure, inner sleeve is contained in the blast cap seat, it is even that the blast cap of this structure has cloth wind, resistance is little, can effectively solve the problem of air compartment deslagging, but the blast cap head is easy to come off, and increase along with running time, the blast cap head quantity that comes off is more and more, and a large amount of material are poured in down a chimney into air compartment, has had a strong impact on boiler and has normally moved, return the of short duration banking fire operation of boiler simultaneously and bring difficulty, restricted the continuous operation of boiler.
Summary of the invention
The purpose of this utility model is to exist the blast cap head easily to come off at present blast cap, influences the normal problem of operation continuously of boiler, and provides a kind of blast cap head not come off, guarantee the bell-jar blast cap of stable operation of the boiler.
The utility model is to address the above problem the technical scheme of taking to be:
A kind of bell-jar blast cap is made up of blast cap head and blast cap seat, and the lower end of described blast cap head adopts embedded structure to be connected with the blast cap seat, offers the eye of wind on described blast cap head.
Wherein, the described eye of wind is 10～12, and is distributed in the equal portion of circumference of blast cap head.
Compared with prior art, the utlity model has following advantage:
Leave certain cavity between the upper end of 1 the utility model blast cap seat and the blast cap head, this cavity can guarantee that the blast cap head is being subjected to not coming off the stable operation of assurance boiler when a large amount of materials impact;
2 the utility model are not provided with inner sleeve in the blast cap seat, saved the making material of blast cap, have reduced the cost of blast cap, and the blast cap seat be in operation not frayed, need not the maintenance, alleviated working strength of workers.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment 1:
As shown in Figure 1, a kind of bell-jar blast cap is made up of blast cap head 1 and blast cap seat 2, and the lower end of described blast cap head 1 adopts embedded structure to be connected with blast cap seat 2, offers the eye of wind 3 on described blast cap head 1.
The equal portion of circumference that the described eye of wind 3 is distributed in blast cap head 1 is advisable with 10～12.
