Description

Technical Field

[0001] This utility model relates to the field of particle size sand recovery technology, specifically a particle size sand recovery device. Background Technology

[0002] Grit is an abrasive material primarily used in grinding and cutting processes. Grit usually refers to silicon carbide grit, with larger sizes indicating finer particles. Silicon carbide grit ranges from 8# to 320#, with particles larger than 320# being called silicon carbide micro powder. This material comes in green and black varieties and is widely used in the abrasive industry, primarily for making grinding wheels and cutting discs.

[0003] Meanwhile, due to its high hardness, it is often used for sandblasting. During the sandblasting process, the scattered sand particles can often be recycled. Therefore, we propose a sand particle recycling device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a particle size sand recovery device that collects falling particle size sand, automatically discharges and conveys the collected particle size sand, and extracts splashed particle size sand, thus carrying out comprehensive recovery work and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a particle size sand recovery device, comprising a base plate, the lower end of which is connected to the upper end of a conveying pipe, a collection cover fixedly connected to the upper surface of the base plate via support legs, a carrying tray disposed inside the collection cover, a fixing mechanism mounted on the carrying tray for fixing the workpiece to be ground, the upper end of a rotating rod fixedly connected to the middle of the lower surface of the carrying tray, the lower end of the rotating rod extending into the interior of the conveying pipe and through a circular hole opened in the conveying pipe to the exterior of the conveying pipe, and a power mechanism fixedly connected thereto, the power mechanism for controlling the rotation of the rotating rod, the rotating rod being rotatably connected to the inner wall of the circular hole via a bearing, and a feeding screw fixedly connected to the rotating rod.

[0006] The design incorporates a collection hood to catch falling sand particles, enabling recycling and reuse. A loading tray is designed to secure the workpiece to be sandblasted. A rotating rod and feeding screw are also included, allowing the feeding screw to rotate automatically as the workpiece rotates, automating the sandblasting process. Before sandblasting, the workpiece is first secured to the loading tray using a fixing mechanism, then the rotating rod rotates, causing the workpiece to rotate as well. The falling sand particles enter the collection hood and are then conveyed into the conveying pipe by the simultaneously rotating feeding screw.

[0007] Furthermore, the fixing mechanism includes clamps, with clamps respectively provided on the front and rear sides of the inner side of the loading tray. The surfaces of the two clamps that are farther apart are respectively rotatably connected to screws, and the two screws are respectively threadedly connected to screw holes opened at corresponding positions on the loading tray.

[0008] First, place the workpiece on the loading tray, then use the rotating screw to drive the two clamping plates to clamp the workpiece.

[0009] Furthermore, the power mechanism includes a motor, the lower surface of the base plate is fixedly connected to the motor via a base, the input end of the motor is electrically connected to the output end of an external power supply, and the output shaft of the motor is fixedly connected to the lower end of the rotating rod.

[0010] The motor is controlled by an external control switch assembly, which in turn drives the rotating rod to rotate.

[0011] Furthermore, the recycling device also includes a dust suppression hood. The dust suppression hood is installed on the upper side of the collection hood. The upper end of the hydraulic rod is fixedly connected to the left side surface of the dust suppression hood through a connecting plate. The lower end of the hydraulic rod is fixedly connected to the corresponding position on the upper side surface of the base plate. The input end of the hydraulic rod is electrically connected through the output end of an external power supply. A sandblasting port is opened at the front end of the dust suppression hood.

[0012] The dust suppression hood is designed to block upward-splashing sand particles, causing them to fall and be collected uniformly. When the dust suppression hood is in operation, the hydraulic rod is controlled by an external control switch group to move the dust suppression hood downward, thereby cooperating with the collection hood to close it.

[0013] Furthermore, the recycling device also includes a suction pipe, the upper surface of the dust suppression cover is connected to the suction pipe, and an exhaust fan is installed inside the suction pipe.

[0014] The system incorporates a suction pipe and an exhaust fan to remove dust, thus reducing environmental pollution.

A rotating rod 13 and a feeding screw 14 are designed so that the feeding screw 14 can rotate when the workpiece is rotated, thus automatically feeding the workpiece. When sandblasting is to be performed, the workpiece is first fixed to the loading tray 10 by the fixing mechanism, and then the rotating rod 13 is rotated, which in turn rotates the workpiece. The workpiece is then sandblasted. The falling sand particles enter the collection hood 2 and are then conveyed into the conveying pipe 3 by the simultaneously rotating feeding screw 14.
