Detailed Description

The following detailed description will be given with reference to specific embodiments, so as to solve the technical problems by applying technical means, and to fully understand and implement the technical effects of the present invention.

Example one

Referring to fig. 2 and 3, a novel U-shaped anti-insect net furnace end spoiler comprises an air inlet pipe 1, wherein an air inlet 11 for air to enter is formed in the side wall of the air inlet pipe 1, a flange nut 2 for installation is arranged at the lower end of the air inlet pipe 1, an anti-insect net 3 is installed on the inner wall of the air inlet pipe 1, the longitudinal cross section of the anti-insect net 3 is of a U-shaped structure and comprises a side portion 3a attached to the inner wall of the air inlet pipe 1 and an arc top end portion 3b connected to one end portion of the side portion 3a, and the side portion 3a is attached to the air inlet 11; specifically, the side portions 3a of the insect-proof net 3 have the same structure as the traditional structure and are used for preventing sundries from entering the air inlet pipe 1, the arc-shaped top portion 3b connected to the top end of the air inlet pipe 1 stops conveying to a certain degree, and air flow can pass through holes of the net structure, so that the functions of turbulence and pressure reduction are achieved; it should be noted that the air inlet pipe 1 may be separately manufactured and then connected to the burner conveying pipeline, or may be directly processed on the original burner gas conveying pipeline, and is not limited to be produced as a separate component herein, or may be processed and manufactured together with the gas conveying pipeline;

according to the technical scheme, the traditional insect-proof net 3 is improved, the arc top end part 3b integrated with the traditional insect-proof net 3 is added in the conveying direction of the air inlet pipe 1, so that the longitudinal cross section of the whole insect-proof net 3 is of a U-shaped structure, and the larger air flow sound is generated due to the fact that fuel gas is directly conveyed to a furnace end to be combusted due to large pressure or large air flow, the air pressure is reduced and the air flow is reduced under the influence of the arc top end part 3b, so that the effects of reducing the air flow sound and reducing the use noise of a furnace are achieved, and the use experience of consumers is improved;

specifically, the arc-shaped top end part 3b of the insect-proof net 3 is integrally formed with the side part 3 a; it is including being radial distribution's support body 31 and installing the netted portion 32 on support body 31, forms arc top portion 3b and lateral part 3a according to the position difference, be equipped with on 1 inner wall of intake pipe with support body 31 complex inner groovy, inner groovy evenly distributed, support body 31 then is formed by the thick support wire combination of many radial circles footpaths, realizes leading and fixed through support body 31 and inner groovy during the installation.

In this embodiment, the side portion 3a and the inner wall of the air inlet pipe 1 are in interference fit, and one side of the insect-proof net 3, which is far away from the arc-shaped top end portion 3b, abuts against the flange nut 2; during installation, the insect-proof net 3 is firstly installed, the frame body 31 is clamped on the inner groove, and then the lower end of the insect-proof net 3 is abutted through the flange nut 2, so that the installation is complete and fixed.

Example two

Referring to fig. 4, compared with the first embodiment, the arc-shaped top end portion 3b is an arc-shaped sheet structure, four air-permeable through holes 33 are uniformly distributed on the arc-shaped sheet structure, and the center of the frame body 31 is connected to the periphery of the arc-shaped top end portion 3 b. Unlike the first embodiment, the arc-shaped top end 3b is a single sheet, and the radial support wire end of the frame 31 is connected to the periphery of the arc-shaped sheet structure, so that the main pressure reduction and flow restriction are realized through the ventilation through hole 33; this is another implementation of the present solution.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
