Description
Technical Field
[0001] This utility model relates to the field of molding sand recycling technology, and in particular to a device for recycling military standard sand dust. Background Technology
[0002] A sand and dust test chamber is a device that uses a fan to blow sand and dust of a certain concentration across the surface of a test sample at a certain flow rate. This allows the test sample (equipment) to be evaluated for its ability to defend against the penetrating effect of dust particles, its ability to defend against the abrasive or clogging effect of sand and gravel, and its ability to be stored and operated when exposed to dry sand or a dusty atmosphere.
[0003] Although existing sand and dust test chambers are equipped with corresponding molding sand recovery mechanisms, the molding sand can easily cause blockage of the discharge port when it is discharged. Moreover, the molding sand dust that floats inside the equipment during operation is not easy to collect, which will affect the quality of the surrounding environment.
[0004] Therefore, it is necessary to provide a device for recovering military-grade sand and dust to solve the above-mentioned technical problems. Utility Model Content

One end of the spiral conveyor blade extends into the discharge pipe. Through the coordinated use of the material drop platform, installation box, drive motor, spiral conveyor blade, discharge pipe, and collection box, it is convenient to recover molding sand while avoiding... The blockage of the discharge pipe necessitates a simpler operation method. During operation, the operator opens the sealed door, places the workpiece on the turntable system, and uses the turntable to rotate the workpiece. Then, the air blowing system is activated, the axial flow fan blows air, and the dust or sand gun is activated to blow air onto the workpiece surface for performance testing. After testing, the molding sand falls onto the discharge platform. The valve on the discharge pipe is then opened, and the drive motor is started, causing the screw conveyor to rotate. Under the action of the screw conveyor, the molding sand on the discharge platform is orderly fed into the discharge pipe and then discharged into the collection box. This method is simple to operate and avoids blockage of the discharge pipe.
[0007] Preferably, a horizontal plate is installed on the outer surface of the device body, and a blower is installed on the top surface of the horizontal plate.

By using the horizontal plate, blower, collection tank, dust suction pipe, filter screen, and grid plate in combination, it is convenient to collect the molding sand dust floating inside the device body when it is working. During operation, the blower is started, and under the action of the blower, the molding sand floating inside the device body is sucked into the collection tank through the dust suction pipe. After being filtered by the filter screen, after a certain amount of molding sand is collected in the collection tank, the valve on the surface of the feed pipe is opened, and then the molding sand inside falls into the collection box.

[0009] Preferably, the bottom of the mounting box is provided with a mounting plate, which is fixedly connected to the unloading platform by fasteners. The top of the mounting box is an arc-shaped structure. By setting the top of the mounting plate to an arc-shaped structure, the phenomenon of sand accumulation is avoided.

Then, the blowing system is activated, the axial flow fan outputs air, and the dust or sand gun is activated, using the air to blow the sand onto the workpiece surface for performance testing. After testing, the molding sand falls onto the discharge platform. Then, the valve on the surface of the discharge pipe is opened, and the drive motor is started, causing the spiral conveyor to rotate. Under the action of the spiral conveyor, the sand is collected and discharged. The molding sand on the material platform enters the discharge pipe in an orderly manner, and then flows into the collection box. This method is simple to operate and avoids clogging of the discharge pipe.
