Log and straw rotary-cut pulverizer with heating device

Abstract

The invention discloses a log and straw rotary-cut pulverizer with a heating device. The log and straw rotary-cut pulverizer comprises a hopper, an upper box, a lower box, a rotor, an air bellow and a motor. The log and straw rotary-cut pulverizer is characterized in that the heating device is arranged between the lower box and the air bellow, and the end face of the side, close to the air bellow, of the upper box is provided with a square feeding port used for feeding during rotary-cut operation; the end, close to the air bellow, of the rotor is provided with a rotary-cut cutterhead, multiple rotary-cut blades are fixedly installed on the rotary-cut cutterhead through high-strength countersunk bolts, and logs with the large diameter can enter the upper box through the square feeding port for rotary-cut operation. The heating device adopts a resistor heating tube heating mode, and the drying intensity can be adjusted by changing the current size of heating resistance wires to meet the drying requirements of straw with different water contents.

Description

technical field [0001] The invention belongs to the technical field of biomass fuel processing equipment, in particular to a log straw rotary cutting pulverizer with a heating device. Background technique [0002] Biomass fuel, which uses logs and various straws as raw materials, is a kind of clean and renewable energy, which has the remarkable characteristics of large stock, wide application and low pollution, and has a broad market prospect. However, the pulverizers, drying, and molding equipment for producing biomass fuels are still in the process of continuous improvement, and large-scale applications have not yet been realized. The pulverizers and dryers sold in the market are two different products, that is, the straw and logs are now crushed into fine powder in the pulverizer, and then put into the dryer for drying operations to remove excess water before they can be used as Raw material for biomass fuel forming machine. This split structure has obvious disadvantage...

AI Technical Summary

Problems solved by technology

This split structure has obvious disadvantages. First of all, fresh straw and logs with high water content cannot be crushed directly, otherwise it will easily cause the outlet of the bellows to be blocked, and the crusher does not have the function of rotary cutting and cannot process thicker logs.

Moreover, it is expensive to purchase a dryer separately, which increases the production cost, loses the comparative advantage with various coal-based fuels, and is not conducive to the promotion and application of biomass fuels.
