Problems solved by technology

[0003] The materials of ordinary tumble dryers generally enter the dryer through the hopper for drying. Generally, such hoppers play the role of material adjustment and transportation, but for the three-pass dryer, the use of ordinary hoppers cannot meet the demand. On the one hand, it cannot be realized. The preheating effect on the material cannot achieve the crushing effect on the fine solid particles existing in the dust material, which will affect the quality of the subsequent drying operation of the material; Very low, resulting in waste of materials, thereby reducing the quality of drying of wet wood powder materials and delaying the construction period, resulting in certain economic losses

Abstract

The invention discloses a powder spraying three-return dryer unloading hopper. The unloading hopper comprises a hopper body; a feed hopper is arranged at the top end of the hopper body, and is communicated with the hopper body; an impeller distributor is arranged in the connected place of the feed hopper and the hopper body; a heating rod is arranged on the side wall of the hopper body; an embedder is arranged in the hopper body; a material receiving port is formed in the top end of the embedder; a hot air connecting pipe is arranged in the material receiving port; an inner cylinder is arranged below the hot air connecting pipe; a cyclone separator is arranged at the top end; an ultrafine crusher is arranged on the inner cylinder below the cyclone separator; a thermal insulation layer is arranged on the side wall of the embedder; the heating rod is arranged in the thermal insulation layer; a material chamber is formed in the bottom end of the hopper body; a material transmission port is formed in the bottom end of the material chamber; and a conveyor is arranged in the material chamber. The device realizes a preheating effect and a crushing effect of fine particles in the material unloading process, guarantees the unloading progress of wet wood powder materials, prevents the waste, and improves the drying quality of the wet wood powder materials.

Description

technical field [0001] The invention relates to a preheating lower hopper device for a drum dryer, in particular to a lower hopper for a powder-spraying three-pass dryer. Background technique [0002] With the continuous improvement of the level of science and technology, there are more and more types of dryers, and the core technology is becoming more and more mature. Dryers are widely used in many industries such as industry and agriculture. Along with staff and researchers With the efforts of various aspects, the drying equipment technology applied in various industries has also been further improved, bringing a lot of convenience to operators and production automation, and improving production efficiency. [0003] The materials of ordinary tumble dryers generally enter the dryer through the hopper for drying. Generally, such hoppers play the role of material adjustment and transportation, but for the three-pass dryer, the use of ordinary hoppers cannot meet the demand. O...
