Abstract
The utility model discloses a flame-proof breathing device used for a flame-proof type accumulator case, which belongs to a mechanical air-breather, and comprises case body side plates (1), bolts (3), blanking plates (9) and end enclosures (2). Air holes (7) are arranged on the case body side plates (1), breather plates (5) are arranged on the air hole (7), breather holes with the size being identical with the size of the air holes (7) are arranged on the breather plates (5), thin filling pieces (8) are arranged among the breather plates, and the blanking plates (9), the breather plates and the side plates (1) are fixed together through the bolts (3), thereby breathing clearances (6) are formed, and both the upper plane and the lower plane of the breather plate (5) adopt flame-proof planes. The device is used for the flame-proof discharging of the hydrogen gas in the downhole flame-proof type accumulator case.
Description
Technical field:
The utility model relates to a kind of air interchanger, the respiratory ventilation device that particularly a kind of flame-proof type accumulator box is used.
Background technology
The inner dress of flame-proof type accumulator box lead acid accumulator under the coal mine, this storage battery is releasing hydrogen gas when normal the use, usually the way that solves is to adopt sealed type lead acid battery or colloid battery that hydrogen is discharged to reduce, but it is also cumulative that the time has been grown hydrogen, its concentration just might be above standard and require 3% setting, under this concentration, run into electric spark and just may cause the battery case internal explosion, have a strong impact on the normal use of flame-proof type accumulator box.
Summary of the invention
The utility model provides flame-proof type accumulator box flame-proof type respiration apparatus under a kind of coal mine, can be used for flame-proof type accumulator box under the coal mine, is used to solve the inner hydrogen that discharges of flame-proof type accumulator box and produces the technical problem of blast.
The present invention solves above technical problem by the following technical programs:
The flame proof respiration apparatus that the flame-proof type accumulator box is used, comprise flame-proof type box side 1, bolt 3, closure plate 9 and end socket 2, described flame-proof type box side 1 is provided with air vent hole 7, it is provided with air permeable plate 5, have on the air permeable plate 5 and air vent hole 7 the same big air-vents, and the air-vent on the air permeable plate 5 is corresponding with air vent hole 7, the ground floor air permeable plate is provided with second layer air permeable plate 5, second layer air permeable plate is provided with the 3rd layer of air permeable plate 5, the 3rd layer of air permeable plate is provided with closure plate 9, between ground floor air permeable plate and second layer air permeable plate, be provided with shim liner 8 between second layer air permeable plate and the 3rd layer of air permeable plate and between the 3rd layer of air permeable plate and the closure plate 9, bolt 3 is with closure plate 9, each layer air permeable plate and side plate 1 are fixed together, breathe gap 6 thereby form, the upper and lower surface of air permeable plate 5 is explosion suppresion surface.
The end socket 2 of described bolt 3 heads is to be welded on the box inside face of flame-proof type box side 1.
Described breathing gap 6 is 0.2 millimeter.
The utility model is used to solve the inner timely discharging of hydrogen under explosion-proof condition that discharges of flame-proof type accumulator box, has avoided producing owing to the savings of hydrogen the generation of the accident of blast.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
Embodiment of the present utility model is as follows:
This flame-proof type respiration apparatus is made up of flame-proof type box side 1, end socket 2, air permeable plate 5, closure plate 9, shim liner 8, bolt 3, elastic washer 4, and wherein the upper and lower surface of air permeable plate is explosion suppresion surface, and the following of closure plate is explosion suppresion surface.On the flame-proof type box side, open a bigger air vent hole, symmetry is opened four less screwed holes around air vent hole, around the box side air vent hole, make suitably big explosion suppresion surface, the ground floor air permeable plate is installed on explosion suppresion surface, on air permeable plate, place four shim liners, the rest may be inferred can install three to four layers, at last closure plate is placed on above the shim liner, and four bolts pass elastic washer 4, closure plate 9, shim liner 8, air permeable plate 5 screw-in screwed holes according to this and tighten.The centre bore of air permeable plate 5 should be identical with the air vent hole size on the box side 1.Can both breathe freely around making respiration apparatus, the size of shim liner gets final product slightly greatly than the corresponding plain washer of the diameter of bolt, and its thickness should be able to guarantee that gap 6 meets the requirement of explosion-proof criteria to flame proof faying face maximal clearance, is generally 0.2 millimeter.Shim liner 8 overlays on the air permeable plate 5, and air permeable plate 5 should have residual area, and its area should meet the minimum widith requirement of explosion-proof criteria to the flame proof faying face.End socket 2 is welded on the flame-proof type box side 1, all welds an end socket below each screw, its objective is explosion-proof (because of threaded engagement does not play the flame proof effect).
