Step type continuous-dehydrating anti-deviating conveyor

Abstract

The invention relates to a step type continuous-dehydrating anti-deviating conveyor, and belongs to the technical field of conveying equipment. The step type continuous-dehydrating anti-deviating conveyor comprises a drive wheel and a drive wheel which are separately arranged outside the two ends of a tunnel type drying tunnel and surround a conveyor belt as well as a tension device, wherein the conveyor belt is provided with a feeding section which passes through the inner part of the drying tunnel and a return section which passes through the lower portion of the drying tunnel; the feeding section is provided with a Z-shaped bend which is distributed in a spaced mode; the Z-shaped bend is formed by enabling the conveyor belt to steer around a front upper roller and a rear lower roller in sequence; and conveyor belt portions at the two sides of the rear lower roller are separately in externally circular contact with bristles of the brush roller supported below the front upper roller. The step type continuous-dehydrating anti-deviating conveyor is beneficial for drying and dehydrating different planes of materials, so that the materials are easily baked; and moreover, material bonding and coking phenomena caused by unsmooth water evaporation loss of long-time contact surfaces of the materials and the conveyor belt can be avoided, so that the dehydrating and drying quality of crops such as fruits, vegetables and tea is improved.

Description

technical field [0001] The invention relates to an anti-deviation conveyor, in particular to a step-type continuous dehydration anti-deviation conveyor, which belongs to the technical field of conveying equipment. Background technique [0002] The dehydration and drying of economic crops such as fruits, vegetables, and tea usually use hot air, infrared, electromagnetic waves, etc. as heat sources, and in most cases, tunnel-type continuous drying equipment is used. Due to the high moisture content of such materials, some of which contain a large amount of bound water, the drying cannot be completed instantaneously, and high temperature will destroy chlorophyll and reduce the content of nutrients, so it needs to be carried out at a lower temperature, so the dehydration of tunnel drying materials is a slow water migration. In the continuous operation process, materials must be evenly arranged on the conveyor belt, and stacking should not occur as much as possible to increase th...

Problems solved by technology

[0003] However, according to the applicant's understanding, the traditional conveyor belt cannot guarantee that the materials will not be stacked, so the subsequent drying process will inevitably have uneven drying and impervious phenomena, and long-term drying will inevitably cause the materials to stick to the conveyor belt, which will not only cause Burnt, and the sticky matter is easy to make the material distribution more uneven, and it will lead to a vicious circle in severe cases

[0004] In addition, the low-temperature drying of fruit and vegetable tea makes the length of the conveyor belt longer, and deviations are prone to occur. At present, traditional anti-deviation methods such as adjusting the tension and adjusting the roller method are not only cumbersome to control and require a large investment in equipment for long-distance transportation of more than 100 meters. , and the effect is not ideal
