Roller cooling screen

Abstract

The invention provides a roller cooling screen. The roller cooling screen comprises a support, a water collection tank and a roller. The bottom of the support is provided with supporting columns. Theupper end of the support is provided with cooling supports and fixed plates for fixing the water collection tank. A water pipe is arranged on the cooling supports. The bottom of the water pipe is provided with water spray holes. A driving wheel and a driven wheel are arranged on one side of the upper end of the support. Two turning wheels are arranged on the other side of the support. The water collection tank is provided with an arc-shaped plate and annular baffles arranged at the two ends of the arc-shaped plate. The bottom of the water collection tank is provided with a water outlet. An internal spiral blade is arranged in the roller. The two ends of the roller are provided with grooves. A rotary ring plate is arranged on the outer side of each groove. The rotary ring plates are arranged on the driving wheel, the driven wheel and the turning wheels. The annular baffles are clamped onto the grooves. The driving wheel is connected with a speed reducer through a driving chain wheel. The speed reducer is connected with a motor. The roller cooling screen facilitates cooling of precoated sand, can reduce the labor intensity of workers and is small in energy consumption and capable ofreducing energy waste.

Description

technical field [0001] The invention relates to the technical field of foundry machinery, in particular to a drum cooling screen. Background technique [0002] In the mold casting industry, after the mixing of coated sand is completed, the temperature is too high, so it cannot be directly packaged and used, and it needs to be cooled before it can be packed into bags. Manual drying is inefficient and increases the labor intensity of workers. The existing cooling screen has a complex structure. And energy consumption is big, increases production cost. Contents of the invention [0003] Based on at least one of the above technical problems, the present invention proposes a new drum cooling screen, which facilitates cooling of coated sand and reduces labor intensity of workers. [0004] In view of this, the present invention proposes a drum cooling screen, comprising: a bracket, a water receiving tank, and a drum; the bottom of the bracket is provided with a pillar, and the u...
