Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening devices, in particular to a device for reducing the burning loss of alkaline phenolic resin sand. Background Art
[0002] Alkali phenolic resin sand is mainly composed of alkaline phenolic resin and filler, and is usually used as a mold material in metal casting. During the use of alkaline phenolic resin, the part that comes into contact with the hot molten metal liquid will become unusable due to burning and needs to be removed.
[0003] Alkali phenolic resin sand can be reused after heat treatment, but the material regenerated by heat treatment of alkali phenolic resin has inconsistent internal particle size. Smaller particles are easily burned and damaged, and larger particles have insufficient fit between alkali phenolic resin sands. The surface roughness is large after hot melt metal casting. A device for screening the particle size of alkali phenolic resin sand is needed. While ensuring the appropriate surface roughness after hot melt metal casting, the burning loss of alkali phenolic resin sand when it contacts with hot melt metal is reduced. For this reason, we propose a device to reduce the burning loss of alkali phenolic resin sand to solve the existing problems. Utility Model Content

[0021] Based on the implementation steps of Example 1: the regenerated alkali phenolic resin sand is transported to the inside of the screening box 5 through the feed port 7, the vibration motor 10 operates at the upper end of the discharge box 3, the swing force generated by the rotation of the rotor acts on the spring 11, causing the sleeve plate 8 to shake, and the regenerated alkali phenolic resin sand flows on the screen 14, and the large-sized vertical sand is intercepted. When passing through the stroke port 16, it is transported to the inside of the discharge box 6, and then transported to the outside, and the resin sand falling downward falls to the upper end of the screen 2 15, and the small-sized resin sand falls downward through the shaking of the screen 2 15. The qualified resin sand is transported to the inside of the discharge box 3 through the stroke port 2 17, and then transported to one side of the partition 4. After passing through the screen 14, the resin sand is directly screened by the screen 2 15, and the large-sized and small-sized resin sands are separated at one time.
