Problems solved by technology

[0002] At present, the high efficiency, environmental protection and easy processing of gas appliances are the development and pursuit of the industry, but the fire cover for the burner generally has secondary air supplementation, insufficient mixing, and high temperature, resulting in low thermal efficiency and excessive CO content in the flue gas. High, especially NOX, an important indicator of environmental protection, fails to meet the requirements of environmental protection and energy-saving products; at the same time, due to the large number of fire holes in the fire cover, each fire hole must be processed one by one, and the production efficiency and production quality are low.

Embodiment 1

[0026] Such as figure 1 , figure 2 As shown, a direct-injection annular fire cover for a burner includes a fire cover body 1 , and the fire cover body 1 includes an inner ring wall plate 2 , an outer ring wall plate 3 and a circular top cover 4 . The annular cover plate 4 is in the shape of an inverted truncated cone, and there are several hollow premixing chambers 5 that open downward on the annular cover plate 4, and the length direction of the premixing chamber 5 is along the busbar direction of the annular cover plate 4 ;

[0027] There are combustion holes 6 on the premix chamber 5 .

[0028] The combustion holes 6 are arc-shaped, and several combustion holes are distributed on concentric circles with different diameters;

[0029] Adjacent combustion holes on two adjacent premix chambers 5 are on a circle.

[0030] The present invention can also be realized in the following way: the combustion hole 6 is in a spiral shape, there are several combustion holes on the pre...

Embodiment 2

[0033] Such as image 3 , Figure 4 Shown, a kind of cutting tool, it comprises driving shaft 7, base 8 and at least two cutting knives 9;

[0034] The cutting knife 9 includes a cylindrical seat 91 and several cutter bodies 92 provided with the ends of the cylindrical seat;

[0035] One end of the drive shaft 7 is fixedly connected to the base 7, and the cylindrical seat 91 of the cutter is fixedly connected to the base 8;

[0036] The length of the cylindrical seat 91 decreases gradually from the radially inner side to the radially outer side of the base 8 of the cutting blade 9 .

[0037] During use, the fire cover body 1 moves along a straight line, and the drive shaft 7 drives the cutting knife 9 to rotate, and the process can be completed.

Embodiment 3

[0039] Such as Figure 5 , Figure 6 Shown, a kind of cutter, it comprises base 8 and at least two cutting blades 9; Cutting blade 9 is circular arc; Cutting blade 9 is arranged on one end of base 8, and the other end of base 8 is a fixed end;

[0040] The cutting knives 9 are distributed in the form of concentric circles of different diameters;

[0041] The cutting blade 9 takes the fixed end of the base 8 as the center of a circle, and the height from the cutting edge to the base 8 gradually decreases from the radially inner side to the radially outer side.

[0042] When the present invention is in use, as Figure 6 As shown, the fire cover body 1 rotates, and the cutter moves forward along a straight line, which can be completed.

Abstract

A direct-injection annular fire cover for a burner, including a fire cover body, the fire cover body includes an inner ring wall plate, an outer ring wall plate and a ring-shaped top cover, the ring-shaped cover plate is in the shape of an inverted truncated cone, and the ring There are several hollow premixing chambers opening downward on the shaped cover plate, the length direction of the premixing chamber is along the generatrix direction of the annular cover plate; there are combustion holes on the premixing chambers. A cutting tool includes a drive shaft, a base and a cutting blade. Due to the adoption of such a structure, it is highly efficient and environmentally friendly: it is fully mixed and supplemented by the suspended fire outlet and air, the direct injection is fully burned, the temperature of the fire cover is reduced, and the thermal efficiency is improved to achieve super-level energy efficiency. At the same time, the NOX in the flue gas is effectively reduced to meet environmental protection requirements. . High production efficiency and high production quality: It solves the defect that each fire hole of the fire cover on the market must be processed once, and the previous dozens or hundreds of fire holes need to be processed dozens or hundreds of times, which is reduced to only one time , greatly improving production efficiency and production quality.

Description

technical field [0001] The invention relates to a cooker burner device, in particular to an annular fire cover of the burner. Background technique [0002] At present, the high efficiency, environmental protection and easy processing of gas appliances are the development and pursuit of the industry, but the fire cover for the burner generally has secondary air supplementation, insufficient mixing, and high temperature, resulting in low thermal efficiency and excessive CO content in the flue gas. High, especially NOX, an important indicator of environmental protection, fails to meet the requirements of environmental protection and energy-saving products; at the same time, due to the large number of fire holes in the fire cover, each fire hole must be processed one by one, and the production efficiency and production quality are low. Contents of the invention [0003] The object of the present invention is to provide a direct-injection annular fire cover for a burner, the fi...
