Multi-stage premixed pipe for gas furnace head

Abstract

The invention discloses a multi-stage premixed pipe for a gas furnace head. The multi-stage premixed pipe a pipe body, a first gas inlet, a second gas inlet and a mixed gas outlet, one end of the pipebody is provided with the first gas inlet and the second gas inlet correspondingly, the other end of the pipe body is provided with the mixed gas outlet, the pipe body is fixedly connected with a fixed plate, and two cavities are formed in the inner part of the pipe body through the fixed plate, the side wall of the fixed plate is provided with a communicating port which is in the horizontal direction, the two ends of the pipe body communicate through the communicating port, one end of the inner part of the pipe body is fixedly provided with a first conduit, and a second conduit is arranged on the outer part of the first conduit in the pipe body, the outer side of the first conduit is equidistantly provided with a first exhaust port, the outer side of the second conduit is equidistantly provided with a second exhaust port, and the other end of the pipe body is provided with a guide rod. The premixed pipe realizes multi-stage mixing of gas, the overall structure is simple, the design is reasonable, the mixing effect of gas is good, the utilization rate of gas is improved, and it is convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of premixing tubes, in particular to a multistage premixing tube for a gas burner. Background technique [0002] The gas stove belongs to the kitchen cooking device stove. In use, the pot is placed on the stove, and the gas in the furnace burns to heat the pot for cooking. In order to improve the combustion effect or combustion efficiency of the stove, it is necessary to The gas is premixed before combustion, and the premixing of the gas requires the use of a premixing tube. [0003] The structure of the current pre-mixing tube is relatively simple, and the mixing degree of the gas is not enough. Insufficient gas mixing will lead to insufficient combustion of the fuel, and insufficient combustion of the fuel will lead to a decrease in firepower, and the furnace core is prone to carbon accumulation, resulting in blockage of the gas outlet. Combustion is incomplete and waste gas increases to pollute the envir...

Problems solved by technology

[0003] The structure of the current pre-mixing tube is relatively simple, and the mixing degree of the gas is not enough. Insufficient gas mixing will lead to insufficient combustion of the fuel, and insufficient combustion of the fuel will lead to a decrease in firepower, and the furnace core is prone to carbon accumulation, resulting in blockage of the gas outlet. Combustion is incomplete and the waste gas during combustion increases and pollutes the environment. For this reason, we propose a multi-stage premixing tube for gas burners
