The invention relates to the technical field of casting auxiliary tools, and discloses a casting waste sand regeneration device based on a thermal expansion and cold contraction principle. The castingwaste sand regeneration device comprises a base, a control device is arranged on the upper portion of the front side of a centrifugal device, an arc-shaped metal sheet is arranged in the control device, a Z-shaped rod is connected to the front side of the centrifugal device, a metal ball corresponding to the arc-shaped metal sheet is arranged at the outer side ends of the Z-shaped rod, a collecting net is connected to the inner side end of the Z-shaped rod, and a torque spring is arranged at the joint of the front end faces of the centrifugal device and the Z-shaped rod. Through continuous falling of an inert film on sand grains, the inert film moves into a funnel of a collecting net under the action of buoyancy, the funnel of the collecting net is gradually blocked, the collecting net drives the metal ball to move on the arc-shaped metal sheet through the Z-shaped rod, and the current in the metal ball and the arc-shaped metal sheet circuit is changed; by means of the structure, theeffects of judging the regeneration degree of the sand grains and automatically controlling operation stopping of equipment are achieved.
Description
Technical field [0001] The invention relates to the technical field of casting auxiliary appliances, in particular to a casting waste sand regeneration device based on the principle of thermal expansion and contraction. Background technique [0002] Casting refers to a processing method in which solid metal is melted into a liquid state and poured into a mold of a specific shape, and then solidified. The metals to be cast include: copper, iron, aluminum, tin, lead, etc. The materials of ordinary castings are raw sand, clay, water glass, resin and other auxiliary materials. Special casting molds include: investment casting, lost foam casting, metal mold casting, ceramic mold casting, etc. my country is a large country in the production of castings, and the output of casting is among the world's forefront, and the amount of raw sand required is also very large. The utilization rate of waste sand is only 20% to 30%. Therefore, the regeneration and reuse of waste sand is an urgent co...
