Combustion boiler with air inlet pipe good in sealing performance

Abstract

The invention discloses a combustion boiler with an air inlet pipe good in sealing performance. The combustion boiler comprises a boiler body. An air inlet channel and a through hole are formed in theboiler body, the through hole is located on the right side of the air inlet channel, a vertical rod is fixedly arranged on the inner side of the through hole, and two clamping grooves are formed in one side of the boiler body and located above and below the through hole correspondingly. A sealing pad is clamped and connected to the inner sides of the two clamping grooves. Threaded rods are movably arranged in the vertical rod, one ends of the threaded rods penetrate the sealing pad and extend to the outer side of the sealing pad, the threaded rods are in threaded connection with the sealing pad, and the ends, away from the vertical rods, of the two threaded rods are fixedly provided with a rotary disc. After the air inlet pipe and the boiler body are movably arranged, the rotary disc is rotated to drive the threaded rods to rotate, the sealing pad and the clamping grooves are clamped and connected, precise contact is conducted, and the connecting pipe sealing effect is improved.

Description

technical field [0001] The invention relates to the technical field of combustion boilers, in particular to a combustion boiler with good air inlet pipe sealing. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which ar...

Problems solved by technology

[0003] At present, the intake pipes of combustion boilers on the market are directly connected to the main body of the boiler. When the boiler is working, the installation of the intake pipes does not have a good sealing effect, which will cause certain leakage. Therefore, there is an urgent need for an intake pipe with good sealing performance. Combustion boilers to solve the above problems
