Detailed ways

The specific embodiments of the present utility model will be further described below with reference to the accompanying drawings and examples.

As shown in Figure 1, the heat pump drying equipment that can automatically discharge materials includes a drying box 12, and a mesh chain conveyor 6 is arranged inside the drying box 12. The mesh chain conveyor 6 is used to carry materials, and the mesh chain The drying box at one end of the conveyor 6 is provided with a discharge port 14, and the drying box 12 below the other end of the mesh chain conveyor 6 is connected to a heat pump unit. When the heat pump unit is running, hot air is generated, and the hot air enters the drying box 12. Inside, the hot air forms a static pressure cavity under the action of the inner wall of the drying box 12, the mesh chain conveyor 6 and the multi-layered materials, and the high-temperature drying hot air passes through the mesh gap of the mesh chain conveyor 6 uniformly through the static pressure cavity. Entering into the multi-layered materials stacked on the upper part of the mesh chain conveyor 6, the materials are heated and dried from bottom to top, and the high-temperature drying hot air flows through the materials and becomes a gas with reduced temperature and increased humidity, under the action of the airflow. Blow up into the atmosphere; the material is laid flat on the top of the mesh chain conveyor 6, which can increase its contact area with the hot air, so that the material is heated evenly, which can significantly improve the drying efficiency and the quality of the output material.

As shown in Figures 1 and 2, the heat pump unit has a heat pump 1, an air valve 2 and an air supply fan 3. The air supply fan 3 adopts a high temperature and high humidity axial flow fan. The air supply fan 3 drives the air flow to generate air flow. The air valve 2 uses In order to control the air intake volume of the heat pump unit, so as to control the air volume discharged from the heat pump unit, the heat pump 1 performs work through electrical energy, provides heat energy, and heats the air flow into hot air. Hot air is blown into the interior of 12; further, the air blower 3 is communicated with the drying box 12 through the air outlet 4, the air outlet 4 is a horn-shaped structure, and the larger end of the air outlet 4 is communicated with the drying box 12. , in the process of blowing, the air pressure at one end of the air outlet 4 connected with the drying box 12 is lower than the other end, which is conducive to the discharge of hot air.

As shown in FIG. 1 , a baffle plate 15 is provided above the mesh chain conveyor 6 perpendicular to its transport direction.
