High-efficiency dryer

Abstract

The invention discloses a high-efficiency dryer which comprises a hearth body (1) and a furnace body (2), wherein the furnace body (2) is horizontally arranged in the hearth body (1), two ends of the furnace body (2), extending out of the hearth body (1), are supported by adopting riding wheels (3), the riding wheels (3) are in contact connection with a rolling ring (4) on the furnace body (2), one end of the furnace body (2) is connected with the output end of a speed change motor (6) through a transmission mechanism (5), a feeding pipe (7) is arranged at one end of the furnace body (2), a valve (8) is arranged on the feeding pipe (7), the other end of the furnace body (2) is sealed by adopting a sealing plate (9), a spiral groove (11) arranged along the radial direction of the furnace body (2) and a stirring rib (12) arranged along the axial direction of the furnace body (2) are arranged in the furnace body (2), and hot air inlets (10) connected with an outside heat source are formed in the hearth body (1). The high-efficiency dryer is simple in structure, convenient to use and good in drying effect, is capable of carrying out vacuum drying, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to a drying device, in particular to a high-efficiency dryer with high drying temperature, high drying efficiency and vacuum drying. Background technique [0002] In the field of asphalt modulation process and activated carbon preparation, it is often necessary to use a dryer to dry raw materials, semi-finished products or finished products. At present, when the common dryer is in use, the furnace body used for drying is driven by a motor to rotate, and at the same time, the material to be dried slides along the inner wall of the furnace body with the rotation of the furnace body to be heated and dried. The above method makes the movement mode of the material to be dried single, and the uneven heating results in poor drying effect, which cannot achieve the expected effect; and the furnace body of the ordinary dryer is made of 304 stainless steel, which can withstand heat up to 400°C and has a low heat resistance temperature. . ...
