Description

Technical Field

[0001] The utility model relates to the technical field of drying racks, in particular to a kudzu powder drying device. Background Art

[0002] The drying room must be equipped with multi-layer drying racks. During the processing of kudzu powder, kudzu powder is obtained through sedimentation and filtration. At this time, the kudzu powder has just been separated from the water and is still stuck together. Remove the stuck kudzu powder and place it on a mesh tray padded with gauze. Place the mesh tray on the multi-layer drying rack and push it into the drying room for drying.

[0003] Generally, companies use multi-layer drying racks of the same height and model, so the placement height of each layer of mesh trays is exactly the same. When hot air is blown in the drying room to dry, the mesh tray located downstream of the hot air blowing and the kudzu powder stuck inside it are easily blocked by the mesh tray upstream of the hot air blowing, resulting in extremely poor contact between the stuck kudzu powder downstream of the hot air blowing and the hot air. The hot air circulation blowing lasts for a long time to dry the stuck kudzu powder in the entire drying room. There are defects such as low drying efficiency, long working time, high energy consumption and time cost, which urgently need to be improved. Utility Model Content

A limiting groove 601 is arranged at the position of the guide rail 6 corresponding to the connecting rod 701, and a roller 702 movably connected to the limiting groove 601 is installed at the end of the connecting rod 701. The angles of the scissor forks 7 corresponding to two adjacent multi-layer drying racks 1 are different, and the height positions of the mesh trays 2 on the two adjacent multi-layer drying racks 1 are staggered;

[0025] A brake universal wheel 8 is installed at the bottom of the movable base frame 3, and a sliding connection seat 9 and a fixed connection seat 10 are respectively arranged on the top of the movable base frame 3. The sliding connection seat 9 is slidably connected with the guide rail 6 on the movable base frame 3, and the sliding connection seat 9 is connected with the connecting rod 701 of the movable end of the scissors 7 corresponding to the guide rail 6 on the movable base frame 3 through a hinge seat 11;
