Technical Field
The utility model relates to a casting sand processing equipment technical field especially relates to a casting sand drying-machine.
Background
The casting is a process method which heats metal into liquid state, then pours liquid metal slurry into a casting mould with a certain shape, makes the liquid metal slurry fill the cavity under the action of external force, such as pressure and gravity, and cools and solidifies to form a casting with the shape of the cavity. Among the casting methods, the application to precision casting is the most common and the most common casting method is the sand casting method. In the sand casting process, the quality of a casting is closely related to the quality of molding sand, and the molding sand is generally formed by mixing molding materials such as casting raw sand, a molding sand binder, auxiliary additives and the like according to a certain proportion. The casting waste products caused by poor quality of the molding sand account for about 30-50% of the total casting waste products. High strength and thermal stability are generally required for molding sand to withstand various external forces and high temperatures, good fluidity and high collapsibility. Therefore, the drying process of the molding sand is a very critical process for manufacturing the molding sand.
Among the prior art, current drying device includes drying chamber and support, the support sets up in the drying chamber, through steam, microwave generating device or resistance element etc. to the grit on the support dry can, place the support with the grit after, need artifically to impel the support to dry indoor or the platform truck pulls, artifical promotion labour is too big, also cause the industrial injury easily, the platform truck pulls easy platform truck overtravel walking, make the support bump the drying chamber easily, cause equipment damage, and the incident takes place.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a casting sand drying-machine is including distributing drying by the fire that has heating element and distributing drying chamber and support that has heating element, drying chamber feed end and discharge end all are provided with the slide rail, the bottom plate of drying chamber bottom is provided with the spout, the spout is close to the discharge end and is provided with the limiting plate, the inside anticollision institution that is provided with of drying chamber, the support bottom sets up the bracing piece, and the bracing piece bottom is provided with the gyro wheel, the bracing piece is kept away from the feed end and is connected with telescopic cylinder, the bracing piece is close to the feed end is provided with limit switch.
Preferably, the pulley is provided with a braking device.
Preferably, the anti-collision mechanism is an anti-collision spring.
Preferably, the included angle between the sliding groove and the horizontal plane is 0-15 degrees.
Preferably, there are two sliding grooves respectively located on two sides of the bottom plate.
Preferably, the limiting plate is fixed to the bottom plate through a rotating shaft, and an air cylinder for driving the rotating shaft to rotate is arranged at one end of the rotating shaft.
The utility model has the advantages that: the utility model provides a casting sand drying-machine, is including distributing drying chamber and the support that has heating element, and drying chamber feed end and discharge end all are provided with the slide rail, the bottom plate of drying chamber bottom is provided with the spout, the spout is close to the discharge end and is provided with the limiting plate, the inside anticollision institution that is provided with of drying chamber, the support bottom sets up the bracing piece, and the bracing piece bottom is provided with the gyro wheel, the bracing piece is kept away from the feed end and is connected with telescopic cylinder axle, the bracing piece is close to the feed end is provided with limit switch and gets into in the drying chamber from the feed end between its drive through telescopic cylinder, and the drying chamber is provided with a plurality of anticollision institution all around, has avoided the support to hit the drying chamber.
