The vibration motor drives the conveying shell to vibrate near the filter plate end. When the mixed material passes through the filter plate, the small particle impurities in the steel shot mixture are screened by the filter plate. The water pump draws external water through the suction pipe, and then the water is rinsed and cleaned through the three-way valve, branch pipe, and water spray block.

At this time, the water pumped by the water pump is sprayed out through the three-way valve, the bifurcated pipe, and the two groups of water spray bars. The water sprayed by the two groups of water spray bars sprays and cleans the surfaces of the two groups of grinding rollers respectively, thereby promoting the removal of residual materials attached to the surfaces of the grinding rollers.

[0020] Beneficial Effects

[0021] The present invention provides a steel shot processing device and a processing method for a casting shot blasting machine. Compared with the prior art, it has the following beneficial effects:

[0022] (1) The steel shot processing equipment of the casting shot blasting machine is provided with a grinding part in the device, and two groups of cylinders are coordinated to adjust the spacing between the two groups of moving frames, grinding rollers, sleeves, and bevel gear assemblies, so that the spacing between the two groups of grinding rollers matches the steel shots of corresponding sizes. During the adjustment process, the sleeve slides along the cross shaft, and the first motor, the cross shaft, the two groups of sleeves, and the bevel gear assemblies cooperate with each other to provide power for the two groups of grinding rollers to rotate in the opposite direction, which is helpful for the subsequent grinding of the surface of the steel shots of changed sizes. This setting makes the grinding end spacing adjustment and the grinding operation independent of each other, thereby improving the adaptability of the grinding end of the device to steel shots of different sizes.

[0023] (2) The steel shot processing equipment of the casting shot blasting machine is provided with a filter element and a water supply element in the device, so that the second motor cooperates with the auger to transport the steel shot and impurity mixture retained in the conveying shell, and the vibration motor drives the conveying shell to vibrate near the filter plate end. When the mixed material passes through the filter plate, the small particle impurities in the steel shot mixture are screened by the filter plate, and the screened material falls into the recovery box. The water pump draws water from the outside through the suction pipe, and the water is sprayed out through the three-way valve, the branch pipe, and the water spray block. The water sprayed by the water spray block rinses and cleans the steel shot passing through. The remaining water from the rinse is discharged to the recovery end through the second water filter plate, the receiving shell, and the drain pipe. This arrangement has the functions of conveying, grading, filtering, and cleaning the polished steel shot, improving the treatment quality of the device for the steel shot, and facilitating the subsequent shot blasting of the shot blasting machine.

[0024] (3) The steel shot processing equipment of the casting shot blasting machine is provided with a three-way valve in the device. After the steel shot processing is completed, the three-way valve is reversed and the water pump is started. At this time, the water pumped by the water pump is sprayed out through the three-way valve, the bifurcated pipe, and two groups of water spray strips. The water sprayed by the two groups of water spray strips sprays the surfaces of the two groups of grinding rollers to clean them respectively, thereby promoting the fall-off of the residual materials attached to the surfaces of the grinding rollers. The fallen residual materials fall into the conveying shell, and the first water filter plate filters the water in the residual materials. This arrangement realizes the cleaning function of the grinding end, improves the recovery rate of steel shots, and reduces the influence of the residual materials attached to the grinding end on the subsequent grinding.

6. The steel shot processing equipment for casting shot blasting machine according to claim 1, characterized in that: The water supply component (6) comprises a water pump (61) mounted on the support frame (1) for discharging water, a water pumping pipe (65) being mounted on the water pumping end of the water pump (61), a three-way valve (62) for adjusting the water flow direction being arranged on the upper drainage end of the water pump (61), the right side of the three-way valve (62) being connected to the filter element (51), a group of water spray bars (64) for flushing impurities attached to the surface of the grinding roller (43) being mounted on the front side and the rear side of the top of the housing (2), respectively, and a bifurcated pipe (63) for supplying water to the two groups of water spray bars (64) being mounted on the upper end of the three-way valve (62).

7. The steel shot processing equipment for casting shot blasting machine according to claim 6, characterized in that: The bottoms of the two groups of water spray bars (64) are both provided with a plurality of second water spray holes, and the two groups of water spray bars (64) are both fixedly connected to the bifurcated pipe (63).

8. A method for treating steel shot of a casting shot blasting machine, characterized in that: The specific steps include: Step 1: The user adjusts the distance between the two groups of moving frames (42) and the grinding rollers (43) through the two groups of cylinders (41), wherein the moving frame (42) drives the sleeve (44) to slide along the cross shaft (47), and the first motor (46) drives the two groups of grinding rollers (43) to rotate in opposite directions through the cross shaft (47), the two groups of sleeves (44), and the bevel gear assembly (45), respectively, and the steel shot to be processed is introduced into the space between the two groups of grinding rollers (43) in the shell (2) through the feed hopper (3), and the two groups of grinding rollers (43) grind the surface of the steel shot, and the steel shot, the grinding impurities and the mixed impurities fall into the conveying shell (511); Step 2: In step 1, after the conveying shell (511) receives the steel shot, grinds the impurities, and mixes the impurities, the second motor (53) drives the auger (52) to rotate, and the rotating auger (52) conveys the steel shot mixture along the conveying shell (511).
