A high-efficiency combustion equipment for biomass solid fuel

Abstract

The invention discloses a biomass solid fuel high-efficiency combustion equipment, which comprises a channel steel frame, a frame is installed on one side of the top of the channel steel frame, a crushing chamber is installed in the frame, and a first motor is installed on the side of the channel steel frame far away from the frame body , the top of the crushing chamber is equipped with a hopper, and the inner cavity of the crushing chamber is rotatably provided with a first crushing roller and a second crushing roller. In the present invention, by setting two meshing and connected gears, the first crushing roller and the second crushing roller can pass through The first motor crushes biomass solid fuel and coal slime efficiently, and the second crushing roller moves to a certain extent on the waist-shaped hole during the crushing process through the cooperation of the screw and the spring, effectively preventing the first crushing roller from colliding with the second crushing roller. The second crushing roller breaks due to excessive tension during the crushing process, and at the same time ensures that the two gears will not slip, and solves the technical problem that the combustion equipment in the prior art is not efficient in crushing biomass solid fuel.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a high-efficiency combustion equipment for biomass solid fuel. Background technique [0002] Biomass refers to various organisms produced through photosynthesis using the atmosphere, water, land, etc., that is, all living organic substances that can grow are commonly referred to as biomass, and straw is also a part of biomass. Straw is the stem and leaf of mature crops. A general term for parts, usually referring to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugar cane and other crops after harvesting seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen and phosphorus , Potassium, Calcium, Magnesium and organic matter, etc., is a kind of multi-purpose renewable organisms. When burning biomass solid fuel, coal slime will be added to increase the combustion efficiency. [0003] The patent do...

Problems solved by technology

[0004] The object of the present invention is to provide a high-efficiency combustion equipment for biomass solid fuels, which solves the following technical problems: (1) By setting two meshing and connected gears, the first crushing roller and the second crushing roller can be oppositely generated by the first motor Material solid fuel and coal slime are efficiently crushed. By setting the lead screw, spring, and waist-shaped hole, the nut on the lead screw is turned to adjust the contact position between the lead screw and the second bearing seat. Through the cooperation of the lead screw and the spring, the first The second crushing roller moves to a certain extent on the waist-shaped hole during the crushing process, which effectively prevents the first crushing roller and the second crushing roller from being broken due to excessive tension during the crushing process, and at the same time ensures that the two gears will not slip. (2) The positioning bearing on the surface is driven to rotate by the rotation of the extrusion rod, and the positioning bearing drives the cutting blade on the surface to crush the extruded extrusion rod. The output is cut, and the cut extrudate falls into the discharge port, and then the extrudate falls into the fuel inlet through the guidance of the lower guide plate, and then falls into the cavity of the combustion chamber. At the same time, a cutting blade is set to convert the biomass solid fuel The extrudate mixed with coal slime is cut in sections, and through the design of two processes of crushing and extrusion from top to bottom, the biomass solid fuel and coal slime are mixed more efficiently to solve the problem of combustion in the prior art The equipment cannot fully mix the biomass solid fuel and coal slime, and thus cannot guarantee the technical problem of combustion efficiency; (3) The blower blows air into the first air duct and the second air duct respectively, and the air passes through the first air duct Entering the fuel inlet, the air enters the combustion chamber through the second air duct, and increases the air volume to the fuel inlet and the combustion chamber. Through the setting of the first air duct and the second air duct, the air in the lower box is effectively increased, and the air in the combustion chamber is effectively improved. Combustion efficiency, the steam inlet pipe discharges the steam from the external steam engine into the combustion chamber, and the steam outlet pipe discharges the steam in the combustion chamber to the outside. Through the design of the steam inlet pipe and steam outlet pipe, the chamber of the combustion chamber can form a steam cycle, and the steam The heat is efficiently converted into heat energy to ensure the efficient combustion of biomass solid fuel and coal slime in the combustion chamber. At the same time, the steam inlet pipe, steam outlet pipe, and water inlet pipe are designed with on-off valves to increase the convenience of the device. The material becomes dry ash and enters the ash cleaning chamber, and the water inlet pipe draws the external water source to the ash cleaning chamber cavity, and the dry ash melts in the water and falls into the ash hopper, which solves the problem of insufficient air volume and air volume in the equipment during the combustion process of the combustion equipment in the prior art, At the same time, the combustion efficiency is not high, and the dry ash produced after combustion is likely to cause air pollution.
