Powder material dryer based on biomass fuel production and use

Abstract

The invention discloses a powder material dryer based on biomass fuel production and use. The powder material dryer comprises a housing, an inner cylinder, a heating ring, an oil inlet and an oil outlet, wherein the inner cylinder is coaxially arranged in the housing; the heating ring is fixedly arranged between the outer wall of the inner cylinder and the inner wall of the housing; a second support rod installed on the bottom wall of the housing is arranged below a tray; a first electromagnet is installed at the top end of the second support rod; and a first support rod and the second support rod are correspondingly distributed up and down in the initial state. According to the powder material dryer based on biomass fuel production and use, an internal drying structure of a tank dryer is redesigned, and by means of operation of a motor and rotation of a rotating shaft, and a bottom bearing structure can move up and down greatly under the influence effect of electromagnetic repulsion while rotating, stirring, dispersing and drying are conducted, therefore, the drying means are increased, the drying effect is improved, and meanwhile, metal impurities existing in the powder can be rapidly and efficiently screened.

Description

technical field [0001] The invention relates to the technical field of biomass fuel production, in particular to a powder raw material dryer based on biomass fuel production. Background technique [0002] Biomass fuel, which is widely used in daily life at this stage, is obtained through secondary processing of waste materials such as straw and wood. Through the production and use of this type of fuel, the current tension of burning energy materials is alleviated. However, in the process of processing, it is still necessary to ensure the quality of the process and equipment. In the existing technology, the straw waste will be crushed first, and then the moisture in the fiber will be dried, mixed with the adhesive, and shaped and cut. Therefore The quality of the drying effect determines the combustion performance of the subsequent fuel, but the existing similar dryers have the following problems in actual use: [0003] Although it has a certain humidity, the powder raw mate...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a powder raw material dryer based on biomass fuel production to solve the above-mentioned problem in the background technology that although the powdery raw material itself has a certain humidity, the quality of the powdered raw material itself is relatively light, and the conveyor belt dryer If you want to speed up the drying efficiency, it will inevitably cause the powder raw materials to fly away from the conveyor belt. However, due to the unreasonable design of the drying structure in the existing tank type drying structure, the single stirring drying effect is poor, and the airflow drying is extremely difficult. Easy to lead to the problem of explosion phenomenon
