Heat conducting pipe type wet material dryer and drying method thereof

Abstract

The invention discloses a heat conducting pipe type wet material dryer which comprises a support. A heating drum is arranged on the support, rotatable heat conducting pipes are arranged in the heating drum, and scraper plates are arranged on the peripheral heat conducting pipes. The whole support is obliquely arranged, the higher end of the heating drum of the dryer is connected with a hot blast furnace, the end, close to the hot blast furnace, of the heating drum is provided with a feeding inlet, and the other end of the heating drum is provided with a dried material discharging outlet. The heat conducting pipes are communicated with the hot blast furnace through a first pipeline. High-temperature hot air generated by the hot blast furnace flows through the heat conducting pipes, wet materials to be dried are completely isolated from the high-temperature hot air, and therefore the potential hazard of fires of the materials is eliminated; the wet materials to be dried enter from the high-temperature end close to the hot blast furnace, vapor outlets are formed in the high-temperature end, and when the wet materials enter the high-temperature end, a large amount of generated vapor is directly exhausted from the vapor outlets through a vapor exhaust fan and a cyclone separator; the vapor exhausting effect is good, the material drying effect is good, and the drying efficiency is high.

Description

technical field [0001] The invention relates to the technical field of dryers, in particular to a heat-conducting tube type wet material dryer and a drying method thereof. Background technique [0002] Existing wet material dryers generally include tumble dryers and heat-conducting tube dryers. In the traditional tumble dryer, the wet material inlet is close to the hot air inlet. When the dry wet material enters the dryer, it is in direct contact with the high-temperature hot air generated by the hot blast stove, and rolls along with the rolling of the cylinder. It is easy to catch fire, and even dust explosion occurs, which is a potential safety hazard; the water vapor generated by drying is extracted from the discharge end. During the drying process, the material and water vapor tumble together, the drying efficiency is not high, and the drying effect is not good. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcom...
