Abstract

Disclosed is a rotary drum dryer internally provided with a screen cloth. The drum screen cloth of the dryer is installed in an inner cavity of a drum body. A transmission gear, a front roller ring and a rear roller ring are arranged on the outer wall of the drum body. The drum body is supported on a front riding wheel and a rear riding wheel through the front roller ring and the rear roller ring. The transmission gear is connected with a motor through a coupler and a speed reducer. Raising plates are evenly installed on the inner wall of the drum body. A discharging device is installed at the tail of the drum body. According to the rotary drum dryer, the problem that materials inside the drum body are thrown unevenly after being raised by the raising plates can be effectively avoided, the materials can directly absorb heat of the internally-arranged drum screen cloth, the drying efficiency of the dryer is improved, meanwhile, abrasion caused by the materials to the drum body is reduced, and the service life of the drum body is prolonged.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer production equipment, in particular to a rotary drum dryer with a built-in screen. Background technique [0002] The rotary drum dryer is a common drying equipment in the phosphorus compound fertilizer industry. It is also widely used in mining, metallurgy, cement and other industries. In the existing rotary drum dryer, the material in the barrel is repeatedly picked up by the lifting plate and then thrown, so as to exchange heat with the hot air to achieve the purpose of drying the material. The efficiency is not high, the impact of the material on the cylinder is large, and the cylinder wears quickly. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rotary drum dryer with a built-in screen, which can not only make the material curtain passing through the drum screen more uniform, but also prolong ...
