Embodiment Construction

[0036] The application will be described in further detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 As shown, a cooling device for coated sand includes a pair of racks 1 distributed at right angles, and each rack 1 is provided with a strip-shaped drum 2 . The drum 2 is horizontally rotatably connected to the frame 1, and a connecting funnel 3 is arranged between a pair of drums 2 .

[0038] Such as figure 1 As shown, the frame 1 is provided with a water spray pipe 11 directly above the drum 2 , and the length direction of the water spray pipe 11 is the same as that of the drum 2 . The outer wall of the lower end of the water spray pipe 11 is provided with a water spray port 12 , and the frame 1 is provided with a pool 13 directly below the drum 2 .

[0039] When the above cooling device is used, the coated sand is poured into the drum 2, and the coated sand is transported by the drum 2 at the same time. After the coated sand is transfe...

Abstract

The application discloses a cooling device for coated sand, which relates to the field of coated sand production, which includes a frame and a strip-shaped drum, the drum is connected to the frame for horizontal rotation, and the inner wall of the drum is provided with a reamer, and the frame There are a pair of support frames respectively located at both ends of the drum, and a support rod that runs through the drum is horizontally arranged on the support frame. A plurality of spatulas that touch the inner wall of the drum are hinged on the support rods, and a drive for controlling the turning of the spatula is arranged inside the drum. mechanism. The application has the following advantages and effects: by setting the reciprocating scraper, the automatic lifting of the coated sand is realized, so that the coated sand is more dispersed and a large area contacts the inner wall of the drum, and the rapid cooling of the coated sand is realized. Thereby, the cooling efficiency of the coated sand is improved.

Description

technical field [0001] The application relates to the field of coated sand production, in particular to a cooling device for coated sand. Background technique [0002] Coated sand is molding sand or core sand whose surface is covered with a layer of solid resin film before molding. During the production and processing of coated sand, the sand is usually preheated to a certain temperature by thermal method, then resin is added to melt it, stirred to coat the resin on the surface of the sand grains, and coated sand is obtained after cooling. [0003] Chinese patent CN208743613U discloses a coated sand cooling device, which includes a drum and a base. The inside of the drum is provided with helical teeth, the drum is covered with a protective cover, and the top of the protective cover is provided with a water distribution pipe. A water outlet is arranged under the cover. [0004] When the cooling device in the related art is working, cold water is used to spray the outer wall...
