Abstract
The utility model relates to a fire extinguishing device for offgas of a mining explosionproof diesel engine, in particular to a bead type flame arrestor for a mining explosionproof diesel engine, which solves the problem that the prior flame arrestor adopts a fence type structure, has high manufacture cost, is difficult to replace and clean, and is easy to block an air flue. The bead type flame arrestor for the mining explosionproof diesel engine comprises a hollow round tube, wherein a receiving tray of the flame arrestor is fixed on the outer ring of the upper end surface of the hollow round tube, an upper sieve sheet and a lower sieve sheet fixed with the inner wall of the hollow round tube are respectively arranged on both ends of the hollow round tube, through holes are all formed onthe two sieve sheets, compact toughened glass beads arranged in a staggered manner are encapsulated in a hollow cavity formed by the two sieve sheets, a layer of elastic stainless steel wire is layedbetween the inner side of the upper sieve sheet and the toughened glass beads, and an elastic retainer ring is clamped and fixed on the outer surface of the upper sieve sheet. The utility model has the advantages of simple structure, reasonable design, small volume, light weight, convenient disassembly, maintenance and cleaning, better fire resistant effect and lower manufacture cost compared with the fence type flame arrestor.
Description
Technical field
The utility model relates to a kind of anti-explosion diesel engine for mine tail gas extinguishing device, is specially a kind of anti-explosion diesel engine for mine pearl type spark arrester.
Background technology
At present, for the material transportation in narrow space, low stoop way under the coal mine, diesel engine on traditional haulage vehicle needs for downhole safety, in inlet and exhaust system, all adopt spark arrester, its objective is for prevent that flame in the cylinder of diesel engine from may return or waste gas in flame directly lead to atmosphere, flame is extinguished through spark arrester.
The existing used spark arrester of domestic anti-explosion diesel engine is paling form, and it is superimposed by one group of stainless steel fence sheet and forms, and the gap between the fence sheet must not be greater than 0.5mm.This spark arrester processing cost height, and weight is big, it is also relatively more difficult to change the fence sheet that damages, be unfavorable for operation, and after work a period of time, cause in the exhaust emissions process carbon distribution easily, greasy dirt is sticking stays in the barrier board gap, stops up the air flue phenomenon, cause diesel engine power to descend, very difficult again cleaning.
Summary of the invention
The utility model adopts the paling form structure in order to solve existing spark arrester, has processing cost height, difficult replacing, easily stops up problems such as air flue, difficult cleaning, and a kind of anti-explosion diesel engine for mine pearl type spark arrester is provided.
The utility model is to adopt following technical scheme to realize: anti-explosion diesel engine for mine pearl type spark arrester, comprise hollow circular-tube, outer ring, hollow circular-tube upper surface is fixed with spark arrester and connects dish, innovative point of the present utility model is that the hollow circular-tube two ends is provided with the top sieve sheet fixing with its inwall respectively, sieves sheet down, be evenly equipped with through hole on the two sieve sheets, be packaged with closely and staggered tempered glass pearl in the formed cavity of two sieve sheets.The utility model utilization closely and staggered tempered glass pearl as the back-fire relief medium, and be encapsulated in the hollow circular-tube with the sieve sheet, simple in structure, processing cost is lower, and result of use is fine.
In order further to optimize the structure of this spark arrester, also comprise following structure design, lay one deck elastic stainless steel silk between described top sieve sheet inboard and the tempered glass pearl, make and play positioning action by spark arrester inner tempered glass pearl non-loosening when rocking; The described top sieve sheet outside fixes flexible back-up ring, and hollow circular-tube upper surface inner ring is offered locating slot, and circlip fixes in locating slot, and circlip can play further positioning action to elastic stainless steel silk or top sieve sheet; Described top sieve sheet and the through hole that sieves on the sheet down are strip.
Compared with prior art, the utility model is simple in structure, reasonable in design, volume is little, in light weight, and the processing and manufacturing cost is low than the paling form spark arrester, and dismounting, maintenance, cleaning are convenient, and the back-fire relief effect is better.

Among the figure: the 1-hollow circular-tube, the 2-spark arrester connects dish, and 3-top sieve sheet, 4-be the sieve sheet down, 5-through hole, 6-tempered glass pearl, 7-elastic stainless steel silk, 8-circlip, 9-locating slot, 10-cooling and purifying water tank, 11-exhaust cap.
The specific embodiment
Anti-explosion diesel engine for mine pearl type spark arrester, as shown in Figure 1, 2, comprise hollow circular-tube 1, outer ring, hollow circular-tube 1 upper surface is fixed with spark arrester and connects dish 2, it is characterized in that hollow circular-tube 1 two ends is provided with the top sieve sheet 3 fixing with its inwall respectively, sieves sheet 4 down, as shown in Figure 3, be evenly equipped with through hole 5 on the two sieve sheets, be strip, be packaged with closely and staggered tempered glass pearl 6 in the formed cavity of two sieve sheets; Lay one deck elastic stainless steel silk 7 between top sieve sheet 3 inboards and the tempered glass pearl 6; Top sieve sheet 3 outsides fix flexible back-up ring 8, and hollow circular-tube 1 upper surface inner ring is offered locating slot 9, and circlip 8 fixes in locating slot 9.
During concrete the making, after will sieving sheet and spark arrester down and connecing dish and hollow circular-tube processes by figure, press process sequence with three's seam, processing, put into tempered glass pearl, elastic stainless steel silk and top sieve sheet then successively, compress at last and block, make pearl type spark arrester inner tempered glass pearl non-loosening when rocking with circlip.According to shown in Figure 4, this spark arrester is installed between cooling and purifying water tank 10 and the exhaust cap 11 then.
