Description

Technical Field

[0001] The utility model relates to the technical field of metal guardrail production, in particular to a rust removal and phosphating device for metal guardrails. Background Art

[0002] Metal guardrail is a kind of safety protection facility widely used in various places, mainly used for isolation, protection, guidance and beautification of the environment. At present, metal guardrail needs to be rust-removed and phosphated during the production process, and most of the methods of rust-removal and phosphating of metal guardrail are through immersion phosphating treatment in the pickling tank. Since the metal guardrail will produce water mist with acidic substances during the phosphating process in the pickling tank, the upper end of the existing pickling tank is basically an open structure, which cannot effectively treat the generated acid mist, causing the acid mist to cause certain pollution to the surrounding environment.

[0003] In order to solve the above problems, the publication number CN214937826U discloses a "metal guardrail rust removal and phosphating device". The stepper motor drives the screw to rotate and the threaded sleeve moves outside the screw. When the two threaded sleeves move, they can drive the mist suction pipe to move back and forth at the top of the pickling tank, absorb the acid mist at the top of the pickling tank, and reduce the diffusion of the acid mist. However, the device still has certain defects in actual use. For example, although the mist suction pipe can move back and forth, when the mist suction pipe moves to the front, it cannot extract the water mist of the acidic substance floating out from the back of the pickling tank, which causes part of the water mist of the acidic substance to float directly out of the pickling tank. In addition, after the device soaks the metal guardrail, it is not convenient to take out the metal guardrail in the pickling tank. Utility Model Content

The bottom of the air extraction pump 501 is connected to the air supply pipe 503. The bottom of the air supply pipe 503 extends to the inside of the purification box 5. When the metal guardrail is immersed in the pickling solution, water mist containing acidic substances will be generated. At this time, the air extraction pump 501 can be turned on to use the air extraction The pipe 502 pumps the water mist of the acidic substance in the box body 1 into the air supply pipe 503, and then transports the water mist of the acidic substance to the purification box 5 through the air supply pipe 503. As the water mist of the acidic substance is continuously pumped into the purification box 5, the purification box 5 flows toward the air outlet 603 and is discharged from the air outlet 603 to the outside of the purification box 5. When the water mist of the acidic substance flows toward the air outlet 603, it passes through the purification frame 601, and the water mist of the acidic substance is purified by the activated carbon particles 602 inside the purification frame 601, thereby preventing the water mist of the acidic substance from being directly discharged to the outside of the purification box 5 to pollute the air.

[0023] Among them, support plates 6 are installed on both sides of the inner wall of the purification box 5, and a purification frame 601 is arranged on the top of the support plate 6.
