Description

Technical Field

[0001] The utility model belongs to the technical field related to metal fiber combustion equipment, in particular to a metal fiber mesh plate used for metal fiber combustion equipment. Background Art

[0002] Metal fiber burners are premixed gas surface combustion. The premixed gas-air mixture flows to the burner head and burns on the metal fiber fabric surface layer with uniform air permeability. Metal fiber burners can achieve clean combustion of gas through metal fiber mesh plates, reduce nitrogen oxides and carbon monoxide produced by combustion on the metal fiber burner surface, and improve combustion efficiency. Among them, the metal fiber mesh plate is the core component of combustion assistance, but the metal fiber mesh plate still has the following disadvantages in actual use:

[0003] 1. During the working process of the metal fiber mesh plate, the gas in it is directly sprayed onto it during the initial work, impacting the metal fiber mesh. During the long-term start-stop or uneven delivery of the gas and air mixture causing impact, the metal fiber mesh plate is easily deformed by the jet impact, causing the mesh size of the fiber mesh to change, affecting the uniformity of combustion;

[0004] 2. When the metal fiber mesh plate is working, the gas passes directly through a single layer of the metal fiber mesh. If the gas transmission is relatively concentrated, the mixing area between the gas and the air will not be large enough, and the gas combustion dispersion will not be good enough, and the combustion efficiency will not be high enough. Utility Model Content

[0005] The purpose of the utility model is to provide a metal fiber mesh plate for metal fiber combustion equipment. By arranging a support plate, a fixed plate, a fixed cylinder and a fixed column, the problems of long-term impact of gas on the metal mesh during the operation of the metal fiber mesh plate easily causing deformation of the fiber mesh and affecting the uniformity of combustion are solved, and the mixing and spreading area between the gas and air when the gas passes through a single-layer fiber mesh is not large enough, the gas combustion dispersion is not good enough, and the combustion efficiency is not high enough are solved.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a metal fiber mesh plate for metal fiber combustion equipment, comprising a supporting disk, a fixing disk, a fixing tube and a fixing column. The supporting disk is vertically penetrated in an annular array and movably connected with fixing columns. The top of the supporting disk outside each fixing column is fixed with a tightening spring. The bottom end of the fixing column is fixed with a threaded column. The bottom ends of all the threaded columns are commonly threadedly connected with the fixing disk. The bottom end of the fixing disk is fixed with a fixing tube. When working, the fixing tube is movably connected thereto through the supporting disk, and the tightening spring absorbs the impact of the pre-mixed gas-air mixture sprayed on the metal mesh 1 and the metal mesh 2 after tightening. The metal mesh 1 is fixed therein through the fixing disk, and the fixing ring is fixed thereon through the fixing tube, and connected with the fixing disk.

[0008] Furthermore, the support plate is provided with insertion holes in a circular array, and a fixing opening is vertically provided in the center of the support plate, and the support plate is fixed to the output end of the metal mesh combustion device through the fixing opening.

[0009] Furthermore, a metal mesh is fixed vertically through the center of the fixed disk, a sleeve is fixed at the center of the top of the fixed disk, and the sleeve is arranged on the outside of the metal mesh. The fixed disk initially disperses the pre-mixed gas-air mixture passing through the metal mesh.

[0010] Furthermore, a fixing ring is fixed to the bottom end of the fixing cylinder, a second metal mesh is fixed on the inner wall of the fixing ring, and the fixing cylinder fixes the second metal mesh therein through the fixing ring, and the pre-mixed uniform gas-air mixture is further dispersed through the second metal mesh.

[0011] Furthermore, a rotating block is fixed to the top of the fixed column, the top of the pressing spring and the bottom of the rotating block are pressed against each other, and the fixed column is inserted into the socket, and the fixed column and the threaded column are driven to rotate by fixing the rotating block.

[0012] Furthermore, the fixing plate outside the sleeve is provided with mounting screw holes in a circular array vertically therethrough, the bottom end of the threaded column is threadedly connected in the mounting screw hole, and the mounting plate is threadedly connected to the threaded column through the mounting screw hole.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the long-term impact of gas on the metal mesh during the operation of the metal fiber mesh plate easily causes the fiber mesh to deform and affect the uniformity of combustion by arranging a supporting plate, a fixing plate, a fixing cylinder and a fixing column. When the metal fiber combustion equipment is started, the pre-mixed gas-air mixture is rushed to the metal mesh 1 and the metal mesh 2, or the pre-mixed gas-air mixture is unevenly transported and impacts the metal mesh 1 and the metal mesh 2. The impact is transmitted to the fixing plate, driving the fixing column, and reducing the impact by tightening the compression spring, thereby reducing the deformation of the metal mesh 1 and the metal mesh 2 and increasing the durability of the metal fiber mesh plate.

[0015] 2. The utility model solves the problems of insufficient mixing and spreading area between gas and air through a single-layer fiber mesh, insufficient dispersion of gas combustion, and insufficient combustion efficiency by arranging a fixed disk and a fixed cylinder. The support disk is fixed to the outside of the metal fiber combustion device so that the fixed disk connected by the threaded column is fixed thereunder. When the pre-mixed gas-air mixture is output, the pre-mixed gas-air mixture is first conveyed into the sleeve, dispersed through the metal mesh 1 below the sleeve, and then conveyed to the fixed cylinder, and output through the metal mesh 2 at the bottom of the fixed cylinder. The pre-mixed gas-air mixture is further homogenized on the surface of the metal mesh 2 and output for combustion. By arranging the double-layer fiber mesh, the mixing and spreading area between gas and air through the single-layer fiber mesh is larger, the combustion is more sufficient, and the combustion efficiency is higher.
