Problems solved by technology
Most of the current steam rotary dryers adopt the tube type, that is, the heat exchange parts in the dryer are heat exchange tubes. In order to ensure the heat exchange area and the material passing rate, the tube spacing needs to be considered when arranging the heat exchange tubes. Therefore, the unit volume The pipe layout area is small, so the diameter of the equipment is large, resulting in problems such as low reliability of transmission equipment components, high manufacturing and operating costs, etc.
Moreover, the current steam rotary dryer tube is very inconvenient to clean

The invention discloses a plate-type steam rotary dryer, which comprises an inclined cylinder driven by a power device to rotate. A central tube is arranged in the cylinder and heating components are distributed therein. The assembly includes two support tubes and bubble plates distributed along the line at intervals. The heating assembly is axially inserted on the sides of the poles on both sides through the support tubes on both sides. The bubble plates are arc-shaped and on the cross-section Form a multi-layer concentric intermittent ring, the central tube is connected with the support tube through the support rod or the added branch tube, the support tube is connected with the bubble plate, the upper end of the cylinder is connected with the screw feeding device, and the lower end is connected with the end seal by rotation , the upper and lower parts of the end seal cover are respectively provided with a gas outlet and a material outlet, and an external pipe is sealed and passed through the end seal cover. One end of the external pipe is connected and communicated with one end of the central pipe in rotation, the other end is closed and the upper and lower parts are respectively provided with steam mouth and outlet. The invention has high heating area, convenient maintenance and replacement, and convenient cleaning.
Description
technical field [0001] The invention relates to a drying device, in particular to a plate type steam rotary dryer. Background technique [0002] The steam rotary dryer is an indirect heat exchange drying equipment using steam as the heat source. It is often used for drying powder materials in metallurgy, chemical industry, environmental protection, building materials and other industries. Most of the current steam rotary dryers adopt the tube type, that is, the heat exchange parts in the dryer are heat exchange tubes. In order to ensure the heat exchange area and the material passing rate, the tube spacing needs to be considered when arranging the heat exchange tubes. Therefore, the unit volume The pipe layout area is small, so the diameter of the equipment is large, resulting in problems such as low reliability of transmission equipment components, high manufacturing and operating costs, etc. Moreover, the current steam rotary dryer tube is very inconvenient to clean.
