Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the discharge end of the feeding rod is driven by the rotation of the swing shaft to do circular arc reciprocating motion, so that the material is laid on the conveyor belt. During the material laying process, the conveyor belt It is also in continuous movement. In order to ensure that the material can be evenly laid on the conveyor belt, it is necessary to reduce the conveying speed of the conveyor belt, thereby affecting the drying efficiency

Abstract

The invention relates to a vacuum low-temperature belt dryer, which comprises a raw material stirring barrel, a material distributing device and a vacuum drying tank body. A conveying rack is arranged in the vacuum drying tank body; the conveying rack is provided with a conveying belt for conveying materials; the material distributing device comprises a material conveying pipe connected to the raw material stirring barrel, a material conveying pump arranged on the material conveying pipe, a material distributing pipe arranged on the conveying rack and located above the conveying belt and a plurality of material distributing heads connected to the material distributing pipe, wherein the material distributing pipe is connected with the material conveying pipe, and the material distributing heads are distributed along the axis of the material distributing pipe; the axial direction of the distributing pipe is parallel to the width direction of the conveying belt. The device has the effect of improving the material drying efficiency.

Description

technical field [0001] The present application relates to the technical field of drying equipment, in particular to a vacuum low-temperature belt dryer. Background technique [0002] The vacuum belt dryer is a contact vacuum drying equipment in the form of continuous feeding and continuous discharging. The material liquid to be dried directly enters the inside of the dryer in a high vacuum through the conveying mechanism, and is spread on the drying belt inside the dryer. On the top, the special rubber roller driven by the motor drives the drying belt to move along the direction of the dryer cylinder at a set speed. There is a heating plate under the drying belt, which transfers the energy required for drying to the material in the form of contact heat transfer. The material will thus be dried. [0003] At present, the Chinese patent with the authorized notification number CN 203829666 U discloses a material distribution device of a vacuum belt dryer, which includes a vacuu...
