Description

Technical Field

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

[0002] The mesh belt dryer is a continuous drying equipment used for mass production. It is used to dry sheets, strips, granules and some paste materials with good air permeability. It is especially suitable for dehydrated vegetables, Chinese herbal medicines and other materials with high moisture content and heat sensitivity. It has the advantages of high drying rate, high evaporation intensity and good product quality.

[0003] However, the current mesh belt dryer still has some shortcomings. For example, the existing mesh belt dryer has a low heat recovery rate (a large amount of heat will be discharged from the exhaust pipe along with the water vapor), which causes the mesh belt dryer to be continuously heated during operation, which is easy to cause waste of resources and increase the user's use cost, and thus there are certain use defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies and provides a net-belt dryer. Utility Model Content

[0005] The purpose of the utility model is to provide a mesh belt dryer to solve the problems raised in the above background technology.

[0007] Furthermore, the heat exchange mechanism includes a metal heat exchange plate, an air guide groove and exhaust holes, and the metal heat exchange plate is provided with an air guide groove inside, and the metal heat exchange plate is provided with exhaust holes in an array at equal distances inside.

[0008] Furthermore, the heating assembly includes an air heating box, an air supply pipe and an air delivery pipe, and the air supply pipe is fixedly installed on the left side of the air heating box, and the air delivery pipe is arranged parallel to the bottom of the air supply pipe, and the end of the air delivery pipe is fixedly connected to the side of the air heating box.

[0009] Furthermore, the air inlet end of the air guide groove is fixedly connected to the end of the diverter pipe, and the air outlet end of the air guide groove is fixedly connected to the end of the air delivery pipe.

[0010] Furthermore, the end of the support frame is fixedly connected to the side of the dehumidification box, and the other side of the dehumidification box is fixedly connected to the side of the protective shell, and the support frame forms a fixed structure through the dehumidification box and the protective shell.

[0011] Furthermore, the drying component includes a hollow connecting plate, a fixed column and an air outlet, and the fixed column is symmetrically installed on the bottom of the hollow connecting plate, and the air outlet is installed in an array at equal distances on the top of the hollow connecting plate, and the bottom of the hollow connecting plate is connected to the end of the air supply pipe.

[0013] Furthermore, the air outlet end of the air outlet head faces directly below the mesh-belt conveyor mechanism, and the upper part of the mesh-belt conveyor mechanism faces directly above the air inlet end of the air inlet pipe.

[0014] The utility model provides a mesh belt dryer, which has the following beneficial effects:

[0015] 1. The utility model provides a shunt pipe, so that the blower can convey outside air into the interior of the air guide groove during operation, so that the outer surface of the metal heat exchange plate can be at room temperature. When the air inlet pipe conveys the hot steam in the protective shell into the interior of the dehumidification box, the hot air can be automatically heat-exchanged when it contacts the outer surface of the metal heat exchange plate. At this time, water droplets are automatically generated at the bottom of the metal heat exchange plate, and the air conveyed into the air heating box by the air delivery pipe is the hot air that has been preliminarily heated. Therefore, the air heating box can reduce energy consumption when heating the air, thereby improving the heat energy recovery rate of the dryer during operation, and reducing the energy loss and use cost of the dryer during operation.

[0016] 2. The utility model sets the number of heat exchange mechanisms into two groups, so that when the air inlet pipe transports hot steam into the interior of the dehumidification box, the hot air can be in more complete contact with the metal heat exchange plate, thereby improving the heat exchange effect of the heat exchange mechanism and further reducing the water content in the air. In addition, the desiccant drying mechanism is set up to make the water content in the air discharged from the exhaust pipe lower, so that the air discharged from the exhaust pipe will not cause discomfort to the surrounding staff (that is, the air discharged from the exhaust pipe is a gas with a slightly higher temperature and lower water content).
