[0025] An embodiment of the utility model provides a device for removing rust from workpieces used in the production of road height limit frames. The dust-proof component of the device for removing rust from workpieces used in the production of road height limit frames uses two sets of wind knives to blow upward wind to block dust from drifting outwards, and cooperates with a vacuum cleaner to suck away the dust, preventing the dust from drifting into the air, thereby avoiding dust pollution of the air and waste of resources caused by flying sand and gravel.

[0026] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0027] like Figures 1-6 As shown, a workpiece rust removal device for the production of road height limit frames includes: a support frame 1, a rust removal box 11 is provided on the top of the support frame 1, two partition plates 12 are fixedly connected to the inner walls on opposite sides of the rust removal box 11, the two partition plates 12 divide the interior of the rust removal box 11 into two conveying chambers 13 and a rust removal chamber 14, and the two partition plates 12 and the rust removal box 11 are respectively provided with through holes 15 on the opposite sides; a dustproof component, the dustproof component is arranged inside the rust removal chamber 14, and is used to prevent dust from floating into the air, and a conveying component is respectively provided inside the two conveying chambers 13.

[0028] When rust removal is performed on the surface of the raw material steel pipe of the height limit frame, one end of the steel pipe is inserted from the through hole 15 on the left side, and one end of the steel pipe is inserted into the conveying assembly. The steel pipe is conveyed to one side by the conveying assembly. After the steel pipe moves through the rust removal chamber 14, the rust on the surface is removed. During removal, the dustproof assembly can prevent rust from floating out from the through holes 15 on both sides. The steel pipe after rust removal is moved out from the through hole 15 on the far right and it can be removed. A visual window is provided on the front side of the rust removal box 11. Example

[0029] On the basis of Example 1, the dust-proof component includes; a wind knife 2, an air duct 21, an air suction shell 22, a dust suction chamber 23, a filter 24 and a guide plate 25; the wind knives 2 are fixedly installed on the opposite sides of the two partition plates 12, and the two wind knives 2 are respectively located below the through holes 15, and one end of the two wind knives 2 is connected to the air duct 21, one end of the air duct 21 passes through the rust removal box 11 and extends to the outside, an air suction shell 22 is fixedly installed on the inner wall of the rust removal chamber 14 near the top, two dust suction chambers 23 are opened at the bottom of the air suction shell 22, and filters 24 are fixedly installed at the bottom of the two dust suction chambers 23, and two symmetrically arranged guide plates 25 are fixedly installed on the two opposite sides of the bottom of the air suction shell 22, a dust collector 26 is provided on one side of the support frame 1, and a dust suction pipe 27 is provided on one side of the dust collector 26, and the top of the dust suction pipe 27 passes through the top of the rust removal box 11 and is connected to the inside of the two dust suction chambers 23.

[0030] Dust will be generated during rust removal, and rust and other dust will float towards the through hole 15. Before processing, the external air source pipe is connected to the two air ducts 21 respectively. When the air source is turned on, air flow is continuously sent into the air knife 2, and 1 air flow is ejected upward from the top of the air knife 2, thereby forming an air flow wall at the through hole 15. When the dust floats onto the two air flow walls, the dust is driven upward by the upward air flow and moves along the opposite side of the two guide plates 25, so that the dust is moved to the bottom of the air suction shell 22 under the drive of the air flow, and the dust collector 26 is started at the same time. After the dust collector 26 is started, the air inside the two dust suction chambers 23 is continuously extracted through the dust suction pipe 27. Some dust passes through the filter 24 and is directly blown into the two dust suction chambers 23. The two dust suction chambers 23 generate suction to suck the dust into the dust suction pipe 27 and then discharge it into the dust collector 26, thereby preventing dust from floating out of the through hole 15 and polluting the air. Example

[0031] On the basis of Example 1, the conveying assembly includes: a feed roller 3, a mounting frame 31, a mounting frame 32, a pressure roller 33 and a reducer 34; feed rollers 3 are respectively rotated between the inner walls of the two opposite sides of the conveying chamber 13, and mounting frames 31 are respectively provided above the two feed rollers 3, a mounting frame 32 is provided between the inner walls of the opposite sides of the mounting frame 31, and a pressure roller 33 is rotatably connected between the opposite sides of the mounting frame 32, and reducers 34 are fixedly installed at the positions near the two feed rollers 3 on the back side of the rust removal box 11, and the drive shafts of the two reducers 34 are respectively connected to the rotating shafts of the two feed rollers 3, and the opposite sides of the outside of the mounting frame 31 are respectively connected to the inner walls of the opposite sides of the conveying chamber 13, and an electric telescopic rod 35 is fixedly installed on the top of the mounting frame 31, and the bottom end of the electric telescopic rod 35 passes through the mounting frame 31 and is connected to the top of the mounting frame 32.

[0032] Before inserting the steel pipe, the distance between the nip roller 33 and the feed roller 3 is adjusted according to the diameter of the steel pipe. The installation frame 32 is driven to move by controlling the electric telescopic rod 35 to push out or retract. The installation frame 32 drives the nip roller 33 to move to adjust the distance between it and the feed roller 3. After adjustment, one end of the steel pipe is inserted between the nip roller 33 and the feed roller 3, and then the two reducers 34 are started. After starting, the two reducers 34 rotate at the same time with the same rotation direction and speed, thereby conveying the steel pipe to the right. The nip roller 33 starts to press, so that the bottom of the steel pipe fits with the feed roller 3. Example

[0033] On the basis of Example 1, two supporting rollers 4 are rotated between the inner walls on both sides of the rust removal chamber 14 respectively, and the two supporting rollers 4 and the two feeding rollers 3 are located on the same side horizontal plane. A mounting rod 41 is fixedly installed between the inner walls on both sides of the rust removal chamber 14 near the middle, and the mounting rod 41 is located between the two supporting rollers 4, and a sandblasting ring 42 is fixedly installed on the top of the mounting rod 41, and a feeding pipe 43 and an air supply pipe 44 are fixedly installed on the top of the sandblasting ring 42. The top ends of the feeding pipe 43 and the air supply pipe 44 respectively pass through the rust removal box 11 and the air suction shell 22 and extend to the outside. A sand filling 45 is provided on the top of the rust removal box 11, and the top end of the feeding pipe 43 is connected to the bottom of the sand filling 45 and is in communication with the inside.

A funnel 48 is fixedly connected to the bottom of the discharge port 47, and the bottom end of the funnel 48 is in communication with the inside of the collecting box 46.

[0034] The steel pipe is placed on the support roller 4 to play a supporting role. Before rust removal, the external compressed air source is connected to the air supply pipe 44, and then the feeding pipe 43 and the air supply pipe 44 are opened at the same time. Sand flows into the feeding pipe 43 from the sand filling 45. The compressed air flow enters the feeding pipe 43 and drives the air and sand mixed into the sandblasting ring 42, and then is sprayed out by the nozzle on the inner ring of the sandblasting ring 42. The sprayed sand and gravel can remove the rust on the surface of the steel. The removed rust and the sprayed sand and gravel fall to the discharge port 47, and then enter the funnel 48 from the discharge port 47. The rust and sand and gravel are discharged into the collection box 46 through the funnel 48. After the drawer inside the collection box 46 is full, it is pulled out for replacement.
