The pulse bag type dust collector for the mine gravel comprises a lower box body, a middle box body and an upper box body, wherein the lower box body is provided with an air inlet; the middle box body is provided with a control instrument; the upper box body is provided with an air outlet; an ash discharge device is arranged below the lower box body; a filter bag is arranged in the middle box body; a Venturi tube is arranged in the filter bag; a blowing ash discharge device is arranged in the upper box body, and is connected with a blowing pipe; and the blowing pipe is provided with a gas orifice. In the pulse bag type dust collector for the mine gravel, the filtering air speed is selected according to the dust content of the air in every cubic meter in a practical working environment, and the blowing period of the blowing ash discharge device is decided according to the filtering air speed, so that the air current resistance of the filter bag in the dust collector does not surpass a critical value, reasonable running of the dust collector is ensured, and a good dust collecting effect is achieved.
Description
Technical field
The utility model relates to the deduster technical field, especially a kind of mine rubble pulse bag type dust collector.
Background technology
Deduster is since coming out, through being extensive use of both at home and abroad, update, on the performances such as purification dusty gas with on the structure very big improvement is being arranged, but dust removal machine can't be selected the reality of dedusting according to actual conditions in work, the effect of dedusting is also undesirable, after working for a long time, the resistance of circulation of air can increase gradually, and dust removing effects can die down, and influences operating efficiency.
Summary of the invention
In order to overcome the deficiency of the existing back dust removal machine operating efficiency step-down that works long hours: the utility model provides a kind of mine rubble pulse bag type dust collector.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of mine rubble pulse bag type dust collector, comprise lower box, middle casing and upper box, described lower box is provided with air inlet, middle casing is provided with controller, upper box is provided with the gas outlet, described lower box below is provided with ash exhauster, be provided with filter bag in the casing in described, be provided with Venturi tube in the filter bag, be provided with jetting deashing device in the described upper box, described jetting deashing device connects the winding-up pipe, and described winding-up pipe is provided with fumarole, be provided with gas bag in the described jetting deashing device, gas bag connects air compressor and pulse valve, and the described pulse valve left side connects control valve, and the right connects the winding-up pipe, the number of described filter bag and Venturi tube is at least 2, and the number of described fumarole is at least 2.
The beneficial effects of the utility model are: this mine rubble pulse bag type dust collector is selected filtration velocity according to every cubic metre of dustiness in the air in the actual working environment, and decide the cycle of jetting deashing system winding-up according to filtration velocity, so just can guarantee that filter bag can not surpass critical value to gas-flow resistance in the deduster, guarantee the reasonable operation of dust removal machine, dust removing effects is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a dedusting schematic diagram of the present utility model;
Among the figure 1, air inlet, 2, lower box, 3, middle casing, 4, upper box, 5, controller, 6, jetting deashing device, 7, filter bag, 8, Venturi tube, 9, the gas outlet, 10, gas bag, 11, air compressor, 12, control valve, 13, pulse valve, 14, winding-up pipe, 15, filter bag, 16, ash exhauster, 17, fumarole.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, a kind of mine rubble pulse bag type dust collector, comprise lower box 2, middle casing 3 and upper box 4, described lower box 2 is provided with air inlet 1, middle casing 3 is provided with controller 5, upper box 4 is provided with gas outlet 9, described lower box 2 belows are provided with ash exhauster 16, be provided with filter bag 7 in the casing 2 in described, be provided with Venturi tube 8 in the filter bag 7, be provided with jetting deashing device 6 in the described upper box 3, described jetting deashing device 6 connects winding-up pipe 14, described winding-up pipe 13 is provided with fumarole 17, is provided with gas bag 10 in the described jetting deashing device 6, and gas bag 10 connects air compressor 11 and pulse valve 13, described pulse valve 13 left sides connect control valve 12, the right connects winding-up pipe 14, and the number of described filter bag 7 and Venturi tube 8 is at least 2, and the number of described fumarole 17 is at least 2.
This mine rubble pulse bag type dust collector, the gas that will contain dust from the air inlet 1 of deduster enter lower box 2 and casing 3, wherein airborne oarse-grained dust is done tangential motion along lower box 2 in lower box 2, utilize deadweight to be deposited to the bottom of lower box 2, the dust of other parts is followed wind direction in middle casing 3 motions, the filter bag 7 that in middle casing 2, is provided with, utilize filter bag 7 that airborne dust is adsorbed on the filter bag 7, the gas that passes filter bag 7 enters upper box 4 through Venturi tube 8, by gas outlet 9 purified gas is discharged again.
Increase along with the dust removal machine working time, the dust that is adsorbed on the filter bag 7 is more and more, the resistance of 7 pairs of air-flows of filter bag also increases thereupon, cause gas flow to reduce gradually by filter bag 7, be controlled at the scope of deduster energy operate as normal for the resistance that makes 7 pairs of air-flows of filter bag, it is clear just need to carry out periodicity to dust adsorbed on the filter bag 7, deashing is handled by jetting deashing device 6, during deashing, jetting deashing device 6 sends instruction, make the compressed air of pulse valve 13 at the abrupt release 0.4～0.7MPa of action, compressed air pours filter bag 7 by the fumarole 17 over against filter bag 7 on the winding-up pipe 14 with high speed, when compressed air pours filter bag 7 inside, because the cone of Venturi tube 8 was used yesterday, induce again and be several times as much as compressed-air actuated secondary gas flow, so produce a kind of temporary impact ripple, and propagate expansion downwards along the length direction of whole filter bag 7, so just the dust that can will be adsorbed on the filter bag 7 falls from filter bag 7, the dust of forming agglomerate just falls into lower box 2, by ash exhauster 16 dust is discharged deduster again, so just can guarantee that deduster works under a rational working condition always, be with respond well.
Determining of filtration velocity;
According to the concentration of dust in the air, selecting of filtration velocity can be with reference to following table under the normal temperature situation.
The selection of pulse period;
Pulse period (promptly jetting the cycle) is finished a required time of deashing circulation for whole pulse valves on the deduster.The selection of cycle length with enter deduster dust content size, filtration velocity and winding-up are relevant with stream pressure height etc.When blowing gas pressure is defined as 0.4MPa constantly, following table can be selected reference for use.
