Embodiment 1

[0014] Such as figure 1 As shown, the gas-barrier continuous feeding device for a gasifier includes a screw conveyor housing 61, the upper end of the screw conveyor housing 61 is equipped with a hopper 62, and the outside of the screw conveyor housing 61 A feeding motor 63 and a feeding gearbox 64 are installed at the end. The power output end of the feeding gearbox 64 is connected to the conveying dragon 65 located in the screw conveyor housing 61; the screw conveyor housing 61 A one-way plugging door 66 is rotatably installed at the discharge port, and the one-way plugging door 66 is provided with a force applying device that presses the one-way plugging door 66 toward the discharge port. This embodiment In this embodiment, the force application device includes a discharge port arranged obliquely upward and a weight that makes the one-way blocking door 66 abut against the discharge port. This embodiment relies on the one-way seal The weight of the blocking door 66 itself is u...

Embodiment 2

[0018] Such as figure 2 As shown, the gas-barrier continuous feeding device for a gasifier includes a screw conveyor housing 61, the upper end of the screw conveyor housing 61 is equipped with a hopper 62, and the outside of the screw conveyor housing 61 A feeding motor 63 and a feeding gearbox 64 are installed at the end. The power output end of the feeding gearbox 64 is connected to the conveying dragon 65 located in the screw conveyor housing 61; the screw conveyor housing 61 A one-way plugging door 66 is rotatably installed at the discharge port, and the one-way plugging door 66 is provided with a force applying device that presses the one-way plugging door 66 toward the discharge port. This embodiment In the above, the force applying device includes a discharge port arranged obliquely downward and a weight 68 that makes the one-way blocking door 66 abut against the discharge port. This embodiment relies on the weight 68 through the principle of leverage. The weight of is...

Abstract

The invention discloses a gas-blocking continuous feeding device for a gasification furnace, which comprises an auger conveyor; one end of a discharge port of the auger conveyor is provided with a material gas-blocking section without an auger; a one-way blocking door is rotatably mounted at the discharge port of the auger conveyor; a force applying device is disposed on the one-way blocking door and is used for pressing the one-way blocking door to the discharge port; a conveying auger ensures the continuous conveying of the materials; the material gas-blocking section always allows a section of materials at the end of a housing of the auger conveyor, and the section of materials has the gas-blocking effect; the arrangement of the one-way blocking door ensures that when material conveying is stopped, high-temperature flue gas is prevented from overflowing through the housing of the auger conveyor, and also from thawing materials in the housing of the auger conveyor; the invention is simple in structure, reliable in use, and completely suitable for high temperature environment in a gasification furnace.

Description

Technical field [0001] The invention relates to a feeding device for a gasification furnace, in particular to a feeding device for a gasification furnace for recycling, harmless and reducing wastes such as combustible garbage and agricultural straw. Background technique [0002] The prior art uses a gasifier or similar equipment to dry distillation and carbonize wastes such as combustible garbage and agricultural straws to convert them into combustible gas, so that wastes such as combustible garbage and agricultural straws can be recycled, harmless, and reduced. Because of the characteristics of combustible garbage, agricultural straws and other wastes, adding materials to the gasifier becomes a problem. In order to make the gasifier work continuously, a continuous feeding device is required, and no flue gas can be discharged when the feeding is stopped. The feeding device of the existing gasification furnace has a complicated structure, which is not suitable for the feeding of ...
