Description
Technical Field
The invention relates to the technical field of steelmaking equipment, in particular to a high-efficiency sand mixer.
Background
The sand mixer is a device which uniformly mixes all components in the molding sand and effectively coats the surface of the sand by the adhesive. The sand mixer (sand mixer) utilizes the relative motion of a grinding wheel and a grinding disc to crush materials by the action of grinding and grinding the materials placed between the grinding wheel and the grinding disc, and the sand mixer also mixes the materials while crushing the materials. Is an ideal device for producing baking-free bricks, lime-sand bricks, cement bricks, refractory bricks, pulverized and mixed fly ash, boiler slag, tailing slag and industrial waste residues as raw materials for making bricks.
Sand mixers are widely used for mixing molding (core) sand with clay as a binder. The sand mixer is provided with a grinding wheel with a certain weight, and the grinding wheel can revolve around the main shaft of the sand mixer and can rotate around the grinding wheel shaft during sand mixing. The molding sand is ground by the rolling wheel during rolling, so that the molding sand particles are coated with a layer of adhesive film. When the surface sand and the core sand are mixed, the quality of the mixed sand is better than that of other sand mixers. The early 50 s used a roller mill with spring pressure. Because of the adoption of spring pressurization, the dead weight of the rolling wheel is reduced, the higher rotating speed of the main shaft can be used, and the rolling pressure can be automatically adjusted along with the thickness of a rolled sand layer, so that the uniform and consistent sand mixing effect is ensured, and the sand mixing efficiency is improved.
Disclosure of Invention
The invention aims to solve the problems of the sand mixer and provide a high-efficiency sand mixer.
The specific scheme of the invention is as follows: the utility model provides a high-efficient roller mill, has the support, the bottom welding of support has the reduction gear, and the roller mill shell is equipped with at the top of support, and the chassis is equipped with to the bottom of shell, is equipped with outer scraper blade on the chassis, is equipped with interior scraper blade on the outer scraper blade, is equipped with the mixing head on the interior scraper blade, and spring pressure device is all installed to the both sides of mixing head, spring pressure device's both sides all are equipped with the grinding wheel, the feeder hopper is installed at the top of roller mill shell, and driving wheel motor is installed to one side of roller mill shell, and the driving wheel motor lower part is equipped with the motor cabinet.
Preferably, the driven wheel is further mounted at the top of the speed reducer, and the driven wheel is connected with the driving wheel through a belt.
The invention has the following advantages:
1. drying is not needed, the production period is shortened, and energy is saved. 2. The drying process is omitted, the molding sand is easy to compact, the collapsibility is good, the cleaning is easy, the labor intensity of workers is greatly reduced, and conditions are created for realizing mechanized production. 3. The size precision of the casting is high, the external contour is clear, the surface of the casting is smooth and clean, the appearance quality is good, the structure is compact, and the comprehensive quality of the casting is high. The resin sand has better fluidity, is easy to compact, has adjustable demoulding time and high strength after hardening, and does not deform in the subsequent carrying and box assembling processes.
