[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0019] Combine the following Figures 1 to 4 The distributor for the wiped film evaporator according to the embodiment of the present utility model is described in detail.

[0020] like Figures 1 to 4 As shown, the utility model proposes a distributor for a scraper film evaporator, including a spiral blade 1, a spiral blade fixing ring 2, a wire mesh 3, a sleeve 4, and multiple groups of blades 5. The spiral blade 1 is welded to the outer wall of the spiral blade fixing ring 2. The spiral blade 1 is arranged on the outer wall of the spiral blade fixing ring 2 in a clockwise spiral downward distribution along the vertical rotation direction, so that the material forms a liquid film and is thrown onto the cylinder wall under the action of centrifugal force. Multiple groups of blades 5 are welded on the inner wall of the spiral blade fixing ring 2, and the other end of the blade 5 is welded on the outer wall of the sleeve 4. The blade 5 has a 45° inclination angle. When the distributor rotates, an ascending airflow propulsion force is formed to accelerate the discharge of steam. The wire mesh 3 is welded to the spiral blade fixing ring 2 and the lower edge of the sleeve 4. The sleeve 4 is fixed to the stirring shaft of the scraper film evaporator by nailing, and the entire distributor rotates with the shaft. The wire mesh 3 adopts a 40-60 mesh stainless steel wire mesh, which eliminates foam while not hindering the discharge of steam due to too dense mesh.

[0021] Working process: spiral blade 1 is welded to the outer wall of spiral blade fixing ring 2, spiral blade fixing ring 2 is welded to shaft sleeve 4 through multiple sets of blades 5, wire mesh 3 is welded to spiral blade fixing ring 2 and the lower edge of shaft sleeve 4, shaft sleeve 4 is fixed to the shaft by nails, and the whole distributor rotates with the shaft. One component is used to replace two components, which has both liquid centrifugal distribution function and defoaming function. At the same time, the inclined blade structure has a propulsion function for the formed steam, which accelerates the evaporation rate of the solvent in the material, greatly reduces the production cost, and increases the evaporation rate, which is worth promoting.
