Example Embodiment

[0018] Example 1.

[0019] As shown in the figure, a rebar sandblasting and rust removal device 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 reducer, a sprocket mechanism 6, a transmission chain 7, a conveying idler 8 and a steel bar conveying groove 26; The machine is connected to each other and installed at 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 attached to the side shaft of the conveying idler 8, so that the transmission chain 7 drives multiple groups of conveying idlers 8. The conveying idler 8 is installed on the frame 1 through bearings, and two positioning rods are arranged in the middle of the conveying idler 8. The distance between the two positioning rods is adapted to the diamet...

Example Embodiment

[0023] Example 2.

[0024] As shown in the figure, on the basis of Embodiment 1, two sandblasting devices 3 are installed in sequence on the frame, and the process length of each sandblasting device 3 is reduced, and a conveying bracket is arranged between the two sandblasting devices 3 Roller 8; the first sand blasting device adopts coarse steel sand, and the second sand blasting device adopts fine steel sand; in the second sand blasting device, the steel sand outlet 27 is directly connected to the sand tank 23 through the steel sand recovery pipe 22 .

[0025] In this way, the vacancy of the conveying idler can be avoided to be too long, and the driving force for continuous conveying of the steel bar can be ensured; 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 steel grit outlet in the second sand blasting device is directly connected to the sand tank through ...

Abstract

The invention discloses a sand blasting derusting device for a reinforcing steel bar. The sand blasting derusting device comprises a rack, a conveying device, sand blasting devices and a sand suction device. The conveying device comprises a servo motor, a speed reducer, a chain wheel mechanism, a transmission chain, a conveying carrier roller and a reinforcing steel bar conveying groove. Each sand blasting device comprises a sand blasting compartment, a sand blasting gun frame, a gas spray gun frame, a dust collecting compartment and a steel sand recovery compartment. The sand suction device comprises a sand cylinder, a sand shot conveying-out pipe, an air compressor and a spray gun adjusting linkage device. In addition, the two sand blasting devices are sequentially installed on the rack. The sand blasting derusting device has the beneficial effects that sand blasting derusting can be conducted on the reinforcing steel bar in all directions, meanwhile, an internal environment and an external environment can be cleaned, the rack passes through the outer sides of the sand blasting compartments, the conveying carrier roller does not enter the sand blasting compartments either, and the rack and the carrier roller can be prevented from being damaged; and the sand blasting devices are increased, after sand blasting is conducted in a hierarchical manner, rough steel sand is recycled and then cleaned to be reused, and fine steel sand can be directly recycled; and with the comprehensive effect, the production efficiency can be improved, cost is reduced, and the labor protection measure is enhanced.

Description

technical field [0001] The invention relates to the field of derusting technical equipment, in particular to a steel bar blasting derusting device. Background technique [0002] In order to make the metal surface have good cleanliness and roughness, pretreatment such as derusting must be carried out on the surface of the metal structure. The principle of sand blasting rust removal and anti-corrosion construction is to use the pressure generated by the air compressor to make the sand particles gain momentum and spray them on the surface of the steel structural member. The sand particles and the metal surface rub against each other to make the rust attached to the metal surface fall off, and then the anti-corrosion The paint is rolled on the metal surface to form a paint film on the entire metal surface, thereby preventing the erosion of water and air to achieve anti-corrosion effects. [0003] For round steel bars, the existing sandblasting and derusting devices can only san...
