The content of the invention

It is an object of the invention to provide a kind of anti-blocking ignition of sintering process device, this igniter can solve existing sintering machine point The problem of firearm blocks in sintering process.

In order to solve the above problems, the technical solution adopted by the present invention is：

This anti-blocking ignition of sintering process device, including supervisor and more spaced branch pipes, the every branch pipe lower end leads to The burner crossed in hose connecting points stove, it is characterised in that：The every branch pipe passes through horizontal decontamination orifice and supervisor top Connection, the supervisor are obliquely installed in head end is high, end is low, and the supervisor is provided with sewage draining exit close to end.

In the technical scheme of above-mentioned anti-blocking ignition of sintering process device, more specifically technical scheme can also be：The every branch Tube top end is communicated with vertical decontamination orifice.

Further, the supervisor end is provided with flange port.

Further, the sewage draining exit is provided with blow-off pipe.

By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：

1. because branch pipe of the present invention is drawn from supervisor top, supervisor's impurity deposits thereunder, the branch pipe with top Coal gas leading point separates so that and it is in separate type to be responsible for the saltation point of impurity in branch pipe, and impurity is mainly deposited in supervisor, Only deposited on a small quantity in branch pipe, so as to mitigate the cleaning pressure of branch pipe impurity, reduce the probability of branch blockage；Because supervisor is in head End is high, end is low is obliquely installed, and makes the impurity of deposition in the enrichment of supervisor end, and is periodically discharged by sewage draining exit, makes supervisor miscellaneous The deposition cleaning of matter is more simple and convenient；Because branch pipe upper end connects horizontal decontamination orifice, deposited for clearing up branch pipe impurity, and by In branch pipe drawn by supervisor top, therefore impurity will not stay product in the impurity at supervisor, branch pipe connection depositing, branch pipe Cleaning is more thorough, avoids vicious circle；Because the impurity cleaning of supervisor's deposition is carried out in sewage draining exit and blow-off pipe, branch pipe The impurity cleaning of deposition is carried out in vertical decontamination orifice and horizontal decontamination orifice, i.e., the impurity of supervisor and each auto-deposition of branch pipe is clear Reason is in being separate type, therefore, can effectively avoid interfering therebetween；Due to because said structure change, operation It is more reasonable that space becomes big, tubular construction of removing contamination is arranged so that sintering coal gas point device cleaning work difficulty is reduced, intensity is reduced, place The reason time was dropped to 2 ~ 4 hours or so by 6 ~ 8 hours or so.

2. because branch pipe upper end of the present invention is communicated with the presence of vertical decontamination orifice so that the impurity cleaning of deposition can in branch pipe Cleared up from the top down in vertical decontamination orifice, the impurity cleaning for further depositing branch pipe is more simple and convenient.

3. because the present invention is provided with flange port in supervisor end, the interior impurity discharge deposited of supervisor, cleaning are more It is simple and convenient thorough.
