Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, a sludge drying device comprises a barrel, a speed reducing motor 1 is arranged at the top of the barrel, an upper transmission assembly 17 is fixedly connected at the bottom of the speed reducing motor 1, a transmission shaft 2 extending into the barrel is fixedly connected at the bottom of the upper transmission assembly 17, a first linear screw 4 is fixedly sleeved on the outer ring of the transmission shaft 2, a second linear screw 6 fixedly sleeved on the outer ring of the transmission shaft 2 is arranged below the first linear screw 4, a third linear screw 7 fixedly sleeved on the outer ring of the transmission shaft 2 is arranged below the second linear screw 6, a lower transmission assembly 18 fixedly connected with the outer wall of the barrel is connected at the bottom end of the transmission shaft 2, an upper tangent discharge port 15 is arranged at the upper part of the left barrel wall of the barrel, a lower tangent discharge port 13 penetrating through the barrel is arranged below the upper tangent discharge port 15, an upper steam inlet 3 is arranged at the upper part of the right side of the barrel, and a, the below of steam inlet 8 is equipped with the comdenstion water export 9 that runs through the barrel down, and mud import 12 has been seted up to the bottom of the positive outer wall of barrel, and the inside cover of mud import 12 is equipped with feed inlet orifice plate 11.

Spiral support rods 5 are welded between the first spiral 4, the second spiral 6 and the third spiral 7 and the transmission shaft 2, four body support legs 10 are welded at the bottom of the cylinder body, a bottom plate is welded at the bottom of the body support legs 10, a heating cylinder inner wall 16 is arranged on the inner wall of the cylinder body, and a steam interlayer 14 is arranged between the cylinder body and the heating cylinder inner wall 16.

In this embodiment, firstly, after equipment starts, gear motor 1 drives first spiral 4, second spiral 6 and third spiral 7 through transmission shaft 2 and rotates, steam interlayer 14 advances interior heating cylinder inner wall 16 temperature rise of steam back barrel, in being dry material enters into the drying cylinder from mud import 12 and feed inlet orifice plate 11, because at first through feed inlet orifice plate 11 in the material gets into the drying chamber, get into with thin strip shape during the entering, can be cut into the granule in the twinkling of an eye after the strip meets high-speed rotatory three spirochaeta, promote by three spirals, under promotion and centrifugal effect, mud etc. are by dry material and heating cylinder inner wall 16 contact, carry out drying heat transfer. The object to be dried who gets into the desicator is in the particulate state all the time like this, has guaranteed drying efficiency, and the material is less than 60% back material because the reduction of weight when the material moisture content, and the speed that is promoted by the spiral is just faster, and when material dryness (moisture content) reached the requirement when reacing the top, the material was rotatory at a high speed under the promotion of three promotion spirals, has formed centrifugal force, from last tangent line discharge gate 15 automatic departure completion drying process. The upper outlet of the traditional spiral flow dryer is vertically installed, and the discharge port of the spiral flow dryer (utility model) and the drying cylinder enter in a tangent line, so that the dried material can leave the drying chamber under the centrifugal action of the material.

If the moisture content of the dried material is high, a high-speed rotating liquid film is formed on the inner wall 16 of the heating cylinder of the drying chamber under the action of the three-wire spiral, the high-speed liquid film and the inner wall 16 of the heating cylinder carry out efficient heat exchange, the process is that the three spiral bodies are distributed at 120 degrees at the same horizontal position to lift the material for three times, and the three times of material distribution and dynamic heating process are carried out. Thereby achieving the most efficient drying efficiency.

The second factor of high drying efficiency is that the three-line screw rotating at high speed provides kinetic energy for the dried material to run at high speed, and the water evaporation process is the process of water molecules obtaining enough kinetic energy or heat energy to change from liquid water to gaseous water. Compared with the traditional drying machine, in particular to a rotary kiln type drying machine, the drying process is to apply the kinetic energy to the rotary cylinder body, so that the energy is not directly applied to the material to be dried, and the drying efficiency is not good.

The device adopts a three-wire spiral, which can be a one-wire (single) spiral, a two-wire spiral, a four-wire five-wire six-wire spiral and other more spirals.

The device can be provided with one feed inlet or a plurality of feed inlets, and the outlet is provided with one or a plurality of outlets.
