Embodiment Construction

[0018] The present invention will be described in detail below with reference to the drawings, such as figure 1 with 2 Shown: the tumble dryer of this embodiment includes a cylindrical body 1 that is slightly inclined to the horizontal plane, a bracket part 2 that supports the entire body so that it can rotate, and a transmission part 3 that drives the body 1 to rotate. The structure of the bracket part 2 and the transmission part 3 can adopt the existing technology. One end of the body 1 has a feeding port 11, the other end is provided with a discharge port 12, and the inner wall of the body 1 is provided with a copy board 6; A hot blast stove 4 for delivering hot air into the machine body 1. The hot blast stove 4 is in communication with the inside of the machine body 1 through a blower pipe 41. The blower pipe 41 extends from the lower end of the machine body 1 into the machine body 1 Inside; the hot blast stove 4 uses a variable frequency fan 42 that can control the wind spe...

Abstract

The invention discloses a rotary drum dryer comprising an obliquely arranged cylindrical dryer body, a bracket part, a driving part and a hot blast stove, wherein the bracket part is used for supporting the whole dryer body to ensure that the dryer body can revolve; the driving part is used for driving the dryer body to revolve; one end of the dryer body is provided with a feeding hole, and the other end of the dryer body is provided with a discharging hole; the hot blast stove is used for delivering hot air into the dryer body, is communicated with the inside of the dryer body through an air supply pipe, and is used for delivering hot air by using an air speed controllable frequency conversion fan. The air speed can be adjusted by using the frequency conversion fan according to drying conditions; for example, the rotary drum dryer can work at a low air speed when the dryer body is preheated and work at a high air speed when the humidity is relatively high, so that the energy consumption is reduced.

Description

Technical field [0001] The invention relates to a compound fertilizer production equipment, in particular to a rotary drum dryer with good drying effect and energy-saving effect. Background technique [0002] The main body of the tumble dryer is a slightly inclined and rotatable cylinder. The working principle of this device is as follows: the wet material is added from the upper part of the higher end of the cylinder, and when passing through the cylinder, it will be dried by effectively contacting the hot air or heating wall surface in the cylinder. Collect at the lower end of the lower end. [0003] During the drying process, the material moves from the higher end to the lower end under the action of gravity by the slow rotation of the cylinder. Generally, the inner wall of the cylinder is equipped with a forward copying board, which continuously picks up and sprinkles the material to increase the thermal contact surface of the material to increase the drying rate and promote ...
