Abstract
The utility model discloses a flame damper which comprises a flame damper body and a flame protection core, wherein the flame protection core is composed of a plurality of layers of flame protection core trays and each layer of the back-fire relief core trays are evenly provided with inclined through holes. The flame damper adopts the flame protection core trays made of polytetrafluoroethene materials and ensures corrosion resistance, flame resistance and temperature tolerance of the flame protection core trays, and meanwhile adopts a way of combining a plurality of layers of inclined hole plates and effectively achieves the purpose of flame protection.
Description
Technical field
The utility model relates to the spark arrester in a kind of engineering storage tank.
Background technology
In various engineerings were used, some media were that the mordant media such as acid or alkali are arranged, and himself material of the spark arrester of traditional metal material will be corroded.Just must use nonmetallic materials, the shell of spark arrester can adopt the material the same with pipe-line system such as PP, FRPP, PPH, UPVC, CPVC, PVDF etc.But the material of fire-retardant core just can not adopt the material the same with shell equally, the one, because most plastic material is not only not fire-retardant, but also non-refractory, the physical property that adds plastic material has determined that it can not be processed into the fire retardant core plate with the corrugated plate dst of traditional metal materials.Original technology just can only adopt the shell of plastics, the core dish of metal.Such structure will make inner member be corroded very soon, just loses the function of back-fire relief.
The utility model content
The utility model purpose is to provide a kind of spark arrester for the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
A kind of spark arrester of the utility model comprises spark arrester body and fire-retardant core, and described fire-retardant core is made of the multilayer fire retardant core plate, the through hole of uniform inclination on every layer of fire retardant core plate.
Preferably, described fire retardant core plate adopts polytetrafluoroethylene (PTFE) to make.
Preferably, described through hole and spark arrester axle center angle at 45 °.
Preferably, described through hole become concentric circles to arrange, and through hole is oblique all towards the fire retardant core plate center take the fire retardant core plate center as the center of circle.
The utility model has guaranteed corrosion resistance, anti-flammability and the temperature tolerance of fire retardant core plate at the fire retardant core plate that has adopted polytetrafluoroethylmaterial material, adopts simultaneously the mode of the little counter direction jet trays combination of multilayer.Effectively reached the purpose of back-fire relief.
Description of drawings
Fig. 1: the utility model overall structure figure.
Fig. 2: the utility model fire retardant core plate structure chart.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of spark arrester of the utility model comprises spark arrester body 1 and fire-retardant core, and described fire-retardant core is made of multilayer fire retardant core plate 2, the through hole 3 of uniform inclination on every layer of fire retardant core plate.
Preferably, described fire retardant core plate adopts polytetrafluoroethylene (PTFE) to make.
Preferably, described through hole and spark arrester axle center angle at 45 °.
Preferably, described through hole become concentric circles to arrange, and through hole is oblique all towards the fire retardant core plate center take the fire retardant core plate center as the center of circle.
The utility model has adopted the innovation of the manufacturing process of the later fire retardant core plate of nonmetallic materials at equipment.At first the materials aspect adopts polytetrafluoroethylmaterial material: this material has guaranteed the corrosion resistance of fire retardant core plate, anti-flammability, temperature tolerance.Because this non-metallic material is not process traditional corrugated plating form, so innovation has also been arranged on version: the mode that adopts the little counter direction jet trays combination of multilayer.Effectively reached the purpose of back-fire relief.
