Abstract
The utility model discloses a linear net burner of a chemical crosslinking polyethylene foaming device, which comprises a first pipeline, a second pipeline, a third pipeline and a fourth pipeline, wherein the fourth pipeline is positioned in the third pipeline, the first pipeline and the second pipeline are both communicated with the fourth pipeline, and the upper side wall of the third pipeline and the lower side wall of the fourth pipeline are respectively provided with multiple air outlets. The linear net burner disclosed by the utility model has the advantages that combustible gas is input through the first pipeline, combustion-supporting gas is input through the second pipeline, the combustible gas and the combustion-supporting gas are mixed in the fourth pipeline firstly and then input in the third pipeline to be fully mixed, and therefore, the uniformity of a gas mixture is improved, so that the gas mixture at each part of the third pipeline is uniform, the temperature of the third pipeline in the process of burning is kept consistent, and a steel net is heated uniformly, so that the service life of the steel net is prolonged, and compared with the existing steel nets, for the steel net using the linear net burner disclosed by the utility model, the service life can be about 12 months, and the cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of polyethylene foam equipment, and the straight line that especially relates to a kind of processes for chemically crosslinked polyethylene foaming machine burns wire stitcher.
Background technology
Existing processes for chemically crosslinked polyethylene foaming machine comprises the pay-off that sets gradually, horizontal foam device, positive and negative calendering device and wrap-up, its course of work is: at first by pay-off the polyethylene master slice is transported in the horizontal foam device, the polyethylene master slice is exported by obtaining processes for chemically crosslinked polyethylene foam sheet semi-finished product after the chemical crosslinking foaming in horizontal foam device, and then by the positive and negative calendering device processes for chemically crosslinked polyethylene foam sheet semi-finished product are carried out obtaining processes for chemically crosslinked polyethylene foam sheet finished product after the press polish, at last by wrap-up with the rolling of processes for chemically crosslinked polyethylene foam sheet finished product.
Horizontal foam device in the processes for chemically crosslinked polyethylene foaming machine comprise the horizontal foaming furnace that is disposed with three thermals treatment zone and be arranged at horizontal foaming furnace top and with three circulating-heating mechanisms of three corresponding connections in the thermal treatment zone.Be provided with the steel mesh for the annular of bearing product in the horizontal foaming furnace.After steel mesh is left in a collection of product foaming, have residue on the steel mesh.In order to prevent that residue from polluting the next group product, is provided with the burning wire stitcher in the port of export bottom of horizontal foaming furnace.Existing burning wire stitcher comprises for the first pipeline of input fuel gas, for the second pipe of input combustion-supporting gas with for the 3rd pipeline with fuel gas and combustion-supporting gas mixing, be provided with a plurality of ventholes on the 3rd pipeline, discharge by venthole and outside the 3rd pipeline, light after fuel gas and combustion-supporting gas mix in the 3rd pipeline steel mesh is burnt, with the residue burn off on the steel mesh.Because everywhere pressure was inconsistent after fuel gas and combustion-supporting gas mixed in the 3rd pipeline, therefore the gas flow of each venthole is different, everywhere flare temperature is inconsistent after the gas igniting, thereby cause the steel mesh inequality of being heated everywhere, reduced the service life of steel mesh, only have about 6 months the service life of steel mesh at present, cost is very high.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of steel mesh service life of can improving, and the straight line of lower-cost processes for chemically crosslinked polyethylene foaming machine burns wire stitcher.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of straight line of processes for chemically crosslinked polyethylene foaming machine burns wire stitcher, comprise the first pipeline, second pipe, the 3rd pipeline and be positioned at the 4th pipeline of described the 3rd pipeline, described the first pipeline and described second pipe all with described the 4th pipeline communication, described the 3rd pipeline is provided with a plurality of the first ventholes uniformly over against a side of steel mesh, evenly is provided with a plurality of the second ventholes on described the 4th pipeline.
Described the second venthole is positioned on the lower wall of described the 4th pipeline.
Compared with prior art, the utility model has the advantage of by the first pipeline input fuel gas, second pipe input combustion-supporting gas, fuel gas and combustion-supporting gas fully mix in input the 3rd pipeline after at first mixing in the 4th pipeline, improved the uniformity of mist, make the mix throughout gas uniform of the 3rd pipeline output, temperature is consistent when keeping its burning, steel mesh is heated unanimously everywhere, improved steel mesh service life, with respect to existing steel mesh, can reach about 12 months the service life of using straight line of the present utility model to burn the steel mesh of wire stitcher, greatly reduces cost;
When the second venthole is positioned on the lower wall of described the 4th pipeline, increased mist in the 3rd ducted incorporation time, further improve the uniformity of mist.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Embodiment: as shown in the figure, a kind of straight line of processes for chemically crosslinked polyethylene foaming machine burns wire stitcher, comprise the first pipeline 1, second pipe 2, the 3rd pipeline 3 and be positioned at the 4th pipeline 4 of the 3rd pipeline 3, the first pipeline 1 and second pipe 2 all are communicated with the 4th pipeline 4, the 3rd pipeline 3 is provided with uniformly over against a side of steel mesh on the lower wall of a plurality of the first venthole 31, the four pipelines 4 and evenly is provided with a plurality of the second ventholes 41.
In the present embodiment, the first pipeline 1 input fuel gas, fuel gas are natural gas, second pipe 2 input combustion-supporting gases, and combustion-supporting gas is compressed air.
Claims (2)
1. the straight line of a processes for chemically crosslinked polyethylene foaming machine burns wire stitcher, the 4th pipeline that it is characterized in that comprising the first pipeline, second pipe, the 3rd pipeline and be positioned at described the 3rd pipeline, described the first pipeline and described second pipe all with described the 4th pipeline communication, described the 3rd pipeline is provided with a plurality of the first ventholes uniformly over against a side of steel mesh, evenly is provided with a plurality of the second ventholes on described the 4th pipeline.
