Problems solved by technology
At this time, the semi-finished coated sand in the sand mixer is easy to loose and lumpy, and needs to be crushed and then cooled. In the existing production line, two sets of equipment are usually used, vibrating screen and cooling bed respectively. To complete the steps of crushing and cooling, the equipment investment is large, the floor area is large, and the production efficiency is reduced

The invention provides a vibratory cooling screen which is simple in structure, can be used for simultaneously realizing crushing and cooling functions, and has good cooling and screening effects. The vibratory cooling screen comprises a screen body, wherein a vibrating motor is connected to the screen body; the screen body is arranged on a support through a spring. The vibratory cooling screen is characterized in that a feeding screen is arranged on the upper part of one end of the screen body, wherein feeding screen cloth is arranged at the bottom of the feeding screen; a ventilation plate corresponding to a part below the feeding screen is arranged in the screen body; a plurality of blast caps are uniformly distributed on the ventilation plate; a plurality of cooling water pipes are arranged in an array between the feeding screen and the ventilation plate; an air inlet is formed in the sidewall of the screen body below the ventilation plate; an air outlet is formed in the top of the screen body; discharging screen cloth is connected to the front end of the ventilation plate; a discharge port is formed below the discharging screen cloth; and a residue discharge port is connected to one side of the discharging screen cloth.
Description
technical field [0001] The invention relates to sand processing equipment in the foundry industry, in particular to a vibrating cooling screen. Background technique [0002] Coated sand, the surface of the sand grains is covered with a layer of solid resin film or core before molding. The coated sand mainly uses high-quality selected natural quartz sand as raw sand, thermoplastic phenolic resin, urotropine and reinforcing agent as raw materials. Coated sand molding is used in complex castings with high dimensional accuracy requirements, and is one of the best molding materials for automobiles, tractors, hydraulic parts, etc. [0003] When using the thermal method to mix coated sand, first heat the raw sand evenly to 120-150°C, then add the heated raw sand and solid resin to the sand mixer for mixing. After the resin melts, it stays on the sand grains and coats the sand grains. At this time, the semi-finished coated sand in the sand mixer is easy to loose and lumpy, and...
