Description

Technical Field

[0001] The utility model relates to a direct-connected shot blasting machine, belonging to the technical field of shot blasting machines. Background Art

[0002] Shot blasters are used in industries such as foundry machinery, metallurgy, machining, steel structure, aerospace, bridge construction, heavy steel, and light steel. They are used in conjunction with a cleaning machine to clean the metal surfaces of cast, forged, welded, and structural parts, removing grit, scale, and contaminants from the workpiece surface, and strengthening the workpiece surface. In the shot blasting equipment industry, shot blasters are the most important and critical equipment. Their performance plays an absolutely crucial role in the effectiveness of the entire shot blasting system and the speed at which workpieces are cleaned.

[0003] The shot blaster drives the blades to rotate through the impeller, and the centrifugal force throws the shot along the direction of the blades. The shot blasters commonly used at present all adopt a split structure, relying on belt, pulley and motor transmission.

[0004] Conventional belt-driven shot blasters take up a lot of space, require numerous components, are expensive, and suffer losses during power transmission. Furthermore, existing shot blasters are welded integrally to the housing, with welds all around. Because shot blasters often operate continuously under harsh conditions, this can easily wear through certain areas of the sealing plate. This leads to complex repairs, excessive labor, and delayed service life, resulting in high maintenance costs. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned traditional technology and provide a direct-connected shot blasting machine with a fastening structure for connecting the motor and the shot blasting machine. The structure is simple and the manufacturing cost is reduced. The detachable shell improves the convenience of maintenance, saves two-thirds of the maintenance time, and reduces the overall operating cost of the supporting production line.

[0006] The purpose of the utility model is achieved by the following technical measures: a direct-connected shot blasting machine, comprising a motor and a shot blasting machine, a linkage sealing disk is provided between the motor and the shot blasting machine, the linkage sealing disk is fixedly connected to the motor, and the motor and the shot blasting machine are connected together through the linkage sealing disk;

[0007] The shot blasting machine includes a shot-splitting wheel, which is connected to the motor through transmission, and a directional sleeve is sheathed on the outside of the shot-splitting wheel;

[0008] The bottom periphery of the pelletizing wheel is connected to an impeller, and a plurality of blades are evenly arranged on the periphery of the impeller;

[0009] The rear side of the impeller is connected to a coupling disc, which is respectively connected to the linkage sealing disc and the motor;

[0010] A rear labyrinth is provided between the coupling disc and the motor;

[0011] The shot blasting machine is provided with a protective shell on the outside, and an outer shell is provided on the outside of the protective shell. The lower end of the outer shell is open, and the lower end of the protective shell extends out of the outer shell;

[0012] A front labyrinth is provided between the shell and the front end of the directional sleeve.

[0013] As a further improvement of the above technical solution:

[0014] The protective shell comprises a rear end guard plate, a front end guard plate, a top guard plate and side guard plates, which are connected to form a shell with an open lower end.

[0015] The upper part of the shell is arranged above the top guard plate, the lower part of the shell is arranged on the periphery of the rear end guard plate, the front end guard plate and the side guard plates, and a pressing device is provided between the upper part and the lower part of the shell.

[0016] The front sides of the outer shell and the protective shell are provided with a through hole, which is arranged right in front of the pill-splitting wheel, and a pill-sliding pipe is connected to the through hole.

[0017] Due to the adoption of the above technical solution, the advantages of the present invention compared with the existing technology are as follows: when the present invention is working, the steel shot and shot material enter the high-speed rotating shot wheel through the shot chute for initial acceleration, and then enter the high-speed rotating blades through the directional sleeve for secondary acceleration, so that the projectile obtains extremely high centrifugal force. Under the action of centrifugal force, the shot material is guided along the blades and accelerated to the workpiece, thereby achieving the purpose of cleaning and strengthening. The motor and shot blasting wheel are tightly connected and adopt a labyrinth ring sealing method to form a rotatable labyrinth with a slight gap. The centrifugal force brought by high-speed rotation and the labyrinth ring with a slight gap achieve an excellent sealing effect.

[0018] The utility model has a simple structure, reduces manufacturing costs, and the detachable shell improves the convenience of maintenance, saves two-thirds of the maintenance time, and reduces the overall operating costs of the supporting production line.
