Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a vacuum belt dryer. Background Art

[0002] Vacuum belt dryer is a contact vacuum drying equipment with continuous feeding and continuous discharging. The liquid to be dried directly enters the dryer in a high vacuum through the conveying mechanism and is spread on several drying belts in the dryer. The motor drives the special rubber roller to drive the drying belt to move along the direction of the dryer cylinder at a set speed. There are three independent heating plates and one cooling plate under each drying belt. The drying belt fits tightly with the heating plate and the cooling plate, and the energy required for drying is transferred to the material in the form of contact heat transfer.

[0003] In the existing material distribution device, when adding materials, the materials are prone to bridge inside the device, which can easily lead to intermittent blockage of the materials during the discharge process, resulting in uneven material distribution and low practicality. For this reason, we propose a vacuum belt dryer. Utility Model Content

[0024] The spiral surface mounting column 54 is slidably mounted in the slide groove 56 through the slide rod 55 and is rotatably mounted in the barrel 2, which has a supporting and mounting function for the spiral surface mounting column 54, thereby improving the stability of the device;

[0025] The motor 51 drives the rotating shaft 52 to rotate, and the rotating shaft 52 drives the multiple stirring rods 53 to rotate to break up the materials, prevent the materials from bridging, and ensure the normal distribution of the materials.

[0026] There are multiple stirring rods 53, and the multiple stirring rods 53 are evenly distributed on the rotating shaft 52;
