Description

Shot blasting steel grit separation device

Technical Field

The utility model relates to a shot blasting steel grit separating device.

Background

The shot blasting machine is a processing technology for throwing steel sand at high speed to impact the surface of a material body through a sand blasting device. After the casting is sanded, some broken iron and sand blocks on the casting can be mixed with steel sand, the shot blasting effect can be influenced after long-time use, and most of steel sand is screened out through a manual screen by workers at present. The screening mode has high working strength of workers and low efficiency, and is not suitable for the development requirement of industrial modernization.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem of overcoming the defects of the prior art and provides the shot blasting steel grit separation device with high screening efficiency.

The technical scheme adopted by the utility model is that a motor is fixedly arranged on a frame, an output shaft of the motor penetrates through the center of a disc and drives the disc to rotate, one end of a suspension arm is hinged with the frame, the other end of the suspension arm is hinged with a screen box, one end of a connecting rod is hinged with the screen box, and the other end of the connecting rod is hinged with a non-circle center point on the disc.

An upper layer screen and a lower layer screen are arranged in the screen box. The screen box, the upper layer screen and the lower layer screen form an included angle alpha with the horizontal plane. Said angle α is preferably 10 °. This inclination makes the sand material on the screen cloth can fully pass through the screening of screen cloth, can be under the effect of gravity again in addition, discharge the discharge gate on the screen cloth faster, be unlikely to block up the screen cloth. The mesh of the upper layer screen is larger than that of the lower layer screen. The lower one end of sieve case is equipped with top discharge mouth and lower discharge mouth, and the top discharge mouth is as the export that the upper screen cloth was left to sieve the material, and the export that the lower discharge mouth was left to sieve the material as lower floor's screen cloth. The frame is fixedly provided with a hopper.

The sand material that mixes during the use is discharged on the upper screen cloth of sieve incasement by the hopper, the motor drive disc is rotatory, the disc passes through connecting rod drive sieve case left and right sides reciprocating motion, make sand block and the iron plate that is located on the upper screen cloth roll back and forth, sand block and the iron plate that can't pass through upper screen cloth mesh are discharged via the top discharge mouth, the sand material of the mixture through upper screen cloth, pass through the screening of lower floor's screen cloth again, sand block and the iron plate that can't pass through lower floor's screen cloth mesh are discharged by lower discharging opening. And finally, collecting the steel grit penetrating through the meshes of the lower-layer screen, and performing circular shot blasting for use. Therefore, the impurities such as sand blocks, iron blocks and the like in the steel sand can be screened out.

The utility model has the advantages of separating the shot blasting sand block and the shot blasting iron block from the steel sand, reducing the working strength of workers and improving the working efficiency.

FIG. 1 is a front view of a shot blasting steel grit separating device according to the present invention;

fig. 2 is a top view of fig. 1.

Labeled as: 1-frame, 2-motor, 3-disc, 4-suspension arm, 5-sieve box, 6-connecting rod, 7-upper screen, 8-lower screen, 9A-upper discharge port, 9B-lower discharge port and 10-hopper.

Detailed Description

The utility model will be further explained with reference to the drawings.

As shown in figures 1 and 2, a motor 2 is fixedly installed on a frame 1, an output shaft of the motor 2 penetrates through the center of a disc 3 and drives the disc 3 to rotate, one end of a suspension arm 4 is hinged with the frame 1, the other end of the suspension arm 4 is hinged with a screen box 5, one end of a connecting rod 6 is hinged with the screen box 5, and the other end of the connecting rod 6 is hinged with a non-circle center point on the disc 3.

An upper layer screen mesh 7 and a lower layer screen mesh 8 are arranged in the screen box 5. The screen box 5, the upper layer screen 7 and the lower layer screen 8 form an included angle alpha with the horizontal plane. Said angle α is preferably 10 °. This inclination makes the sand material on the screen cloth can fully pass through the screening of screen cloth, can be under the effect of gravity again in addition, discharge the discharge gate on the screen cloth faster, be unlikely to block up the screen cloth. The mesh of the upper layer screen 7 is larger than that of the lower layer screen 8. The lower end of the screen box 5 is provided with an upper discharge hole 9A and a lower discharge hole 9B, the upper discharge hole 9A is used as the outlet of the left screen material of the upper screen 7, and the lower discharge hole 9B is used as the outlet of the left screen material of the lower screen 8. The frame 1 is fixedly provided with a hopper 10.

The sand material that mixes during the use is discharged by hopper 10 on the upper screen cloth 7 of sieve case 5, motor 2 drive disc 3 is rotatory, disc 3 passes through connecting rod 6 and drives sieve case 5 left and right reciprocating motion, make sand block and the iron plate that is located on upper screen cloth 7 roll back and forth, sand block and the iron plate that can't pass through upper screen cloth mesh are discharged via upper discharge gate 9A, the sand material of the mixture through upper screen cloth 7, pass through the screening of lower floor's screen cloth 8 again, sand block and the iron plate that can't pass through lower floor's screen cloth 9 mesh are discharged by lower discharge gate 9B. And finally, collecting the steel grit penetrating through the meshes of the lower-layer screen 8 for circular shot blasting. Therefore, the impurities such as sand blocks, iron blocks and the like in the steel sand can be screened out.
