Embodiment 1
[0019] As shown in the figure, a sandblasting and derusting device for steel bars is installed, including a frame 1, a conveying device 2, a sandblasting device 3 and a sand suction device 4.
[0020] First install the frame 1 and the conveying device 2, the conveying device 2 includes a servo motor 5, a speed reducer, a sprocket mechanism 6, a transmission chain 7, a conveying roller 8 and a steel bar conveying trough 26; wherein the servo motor 5 and the decelerating The machine is connected with each other and installed in the lower part of the frame 1, the reducer is connected to the transmission chain 7 through the sprocket mechanism 6, and the transmission chain 7 is mounted on the side shaft of the conveying roller 8, so that the transmission chain 7 drives multiple groups of conveying rollers 8. The conveying roller 8 is installed on the frame 1 through the bearing, and two positioning rods are set in the middle of the conveying roller 8. The distance between the two po...
Embodiment 2
[0024] As shown in the figure, on the basis of Embodiment 1, two sandblasting devices 3 are installed sequentially on the frame, and the process length of each sandblasting device 3 is reduced, and a delivery support is set between the two sandblasting devices 3 Roller 8; the first sand blasting device adopts coarse steel grit, and the second sand blasting device adopts fine steel grit; in the second sand blasting device, the steel grit outlet 27 is directly connected to the sand cylinder 23 through the steel grit recovery pipe 22 .
[0025] In this way, it can avoid the excessively long vacancy of the conveying roller and ensure the driving force of continuous conveying of the steel bar; when in use, the first sandblasting device uses coarse steel sand for sandblasting, and the second sandblasting device uses fine steel sand for sandblasting; The outlet of the steel grit in the second sandblasting device is directly connected to the sand cylinder through the steel grit recove...
