Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion treatment of steel members, and specifically relates to a surface anti-corrosion treatment device for steel member processing. Background Technique

[0002] Steel members are widely used in many fields such as construction, bridges, mechanical manufacturing, petrochemical industry, etc. However, since steel members are often exposed to various environmental conditions during use, such as the atmosphere, water, soil, etc., they are easily affected by corrosion. In an industrial environment, they will also be corroded by chemical substances. Therefore, it is crucial to perform effective surface anti-corrosion treatment on steel members.

[0003] During the production, transportation and storage processes, steel members are exposed to the air, and dust and particulate matter in the air will adhere to the surface of the steel members. Moreover, rust, iron filings and other impurities will be generated during the processing of steel members. Therefore, when spraying anti-corrosion paint on steel members, impurity particles such as dust and rust will affect the contact between the anti-corrosion paint and the surface of the steel members. If there are impurities on the surface of the steel members, the anti-corrosion paint cannot adhere to the steel members fully and tightly, which will reduce the adhesion strength of the anti-corrosion paint. During subsequent use, the anti-corrosion paint is prone to phenomena such as peeling and flaking, thus unable to effectively protect the steel members.

[0004] In the prior art, workers usually directly wipe with a rag. First of all, it is difficult to remove impurities such as firmly adhered rust and iron filings on the surface of the steel members with a rag. Especially for impurities in some small gaps and corners, the rag cannot effectively reach and clean them, resulting in some impurities still remaining on the surface of the steel members. Moreover, after wiping, when the spraying device is started again, impurities will re-adhere during the intermediate interval time, and thus it is necessary to clean again.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The utility model provides a technical solution:

[0027] Referring to Figures 1 - 6 As shown, a surface anti-corrosion treatment device for steel member processing includes a main body of a spray gun 1, on which a storage barrel 2 for conveying anti-corrosion paint into the main body of the spray gun 1 is provided, including a connector 3 fixedly installed at the bottom of the storage barrel 2, the bottom end of which extends through and into the main body of the spray gun 1, and a liquid outlet is opened at the bottom of the connector 3; an inner cylinder 7 slidably arranged in the main body of the spray gun 1, with a cavity opened inside it, air vents 10 for gas passage are opened at both ends of the inner cylinder 7, and the air vents 10 are communicated with the cavity; a switching mechanism is arranged on the inner cylinder 7, and through grooves 12 communicated with the cavity inside the inner cylinder 7 are opened on it and the inner cylinder 7, the two through grooves 12 are correspondingly arranged up and down and communicated, the through groove 12 is adapted to the liquid outlet, and the switching mechanism abuts against the liquid outlet, and is used to make the through groove 12 move away from or dock with the liquid outlet when sliding left and right along with the inner cylinder 7.

[0028] First, the steps of the main body of the spray gun 1 spraying gas are as follows: The main body of the spray gun 1 is connected to an air compressor through a pipeline, so after the main body of the spray gun 1 is started, gas will enter the main body of the spray gun 1, the gas in the main body of the spray gun 1 enters the cavity inside the inner cylinder 7 through the air vent 10, and then is sprayed from the air vent 10 at the other end of the inner cylinder 7 to the muzzle of the main body of the spray gun 1, and then is sprayed out from the main body of the spray gun 1;

[0029] Secondly, the anti-corrosion paint in the storage barrel 2 enters the main body of the spray gun 1 through the connector 3. First, the liquid outlet of the connector 3 is abutted by the switching mechanism, and the anti-corrosion paint cannot flow out of the connector 3 at this time. When the inner cylinder 7 is moved to the left, the switching mechanism moves together with the inner cylinder 7 until the through groove 12 on the right is moved to correspond to the liquid outlet at the bottom of the connector 3, and then the anti-corrosion paint will flow into the through groove 12 through the liquid outlet, and finally enter the cavity inside the inner cylinder 7 through the through groove 12, and then the gas will blow the anti-corrosion paint in the cavity out of the main body of the spray gun 1 and finally spray it on the steel member;

[0030] Before spraying the anti-corrosion paint, move the inner cylinder 7 to the right to make the through groove 12 move away from the liquid outlet. At this time, the liquid outlet is blocked by the switching mechanism, and the anti-corrosion paint cannot flow into the cavity of the main body of the spray gun 1. At this time, start the main body of the spray gun 1, and the main body of the spray gun 1 can only spray gas. Since the air compressor can compress air, the gas sprayed by the main body of the spray gun 1 has impact force. Then use the high-pressure gas to impact the steel member. The high-pressure gas can generate a strong impact force, which can effectively remove various impurities on the surface of the steel member, including rust, iron filings, dust, etc., and can even clean to small gaps and corners. After removing the impurity particles, move the inner cylinder 7 again to make the anti-corrosion paint flow into the cavity, and then spray paint;

[0031] The switching between the cleaning and spraying processes is very fast, and it also solves the problem of impurities re-adhering after cleaning.

[0032] Refer to Figures 2 - 5 , the opening and closing mechanism includes a baffle 9 provided on the inner cylinder 7. The connecting head 3 is provided with a slotted groove 13. The baffle 9 is slidably connected to the slotted groove 13, and the top of the baffle 9 is located inside the slotted groove 13. A nozzle 14 is fixedly installed at the liquid outlet of the connecting head 3. The baffle 9 is provided with a strip-shaped opening 16 for the nozzle 14 to slide. A blocking component is provided inside the strip-shaped opening 16 for blocking the spray holes at the bottom of the nozzle 14.

[0033] When the inner cylinder 7 is moved, the baffle 9 will slide along the slotted groove 13, and the strip-shaped opening 16 provides space for the nozzle 14, so that when the baffle 9 and the inner cylinder 7 are moved, the strip-shaped opening 16 will move along the nozzle 14. The liquid flows out through the spray holes at the bottom of the nozzle 14. Before reaching the nozzle 14 through the through groove 12, the blocking component presses against the spray holes at the bottom of the nozzle 14 to prevent the anti-corrosion paint from flowing to places other than the through groove 12 and avoid leakage of the anti-corrosion paint.

[0034] Refer to Figures 3 - 4 , the blocking component includes a top plate 11. The outer wall of the top plate 11 abuts against the inner wall of the strip-shaped opening 16. A plurality of springs 17 are fixedly installed between the inner bottom wall of the strip-shaped opening 16 and the bottom of the top plate 11. The spray holes at the bottom of the nozzle 14 abut against the top of the top plate 11.

[0035] The springs 17 always push the top plate 11 upward, so that the top plate 11 can tightly abut against the bottom end of the nozzle 14, blocking the spray holes with the top plate 11 and reducing the risk of leakage of the anti-corrosion paint

[0036] Refer to Figures 3 - 5 , a blocking plate 15 is fixedly installed on the outer wall of the top plate 11. The blocking plate 15 is located inside the through groove 12 and abuts against the inner wall of the strip-shaped opening 16.

[0037] The blocking plate 15 blocks the area between the top plate 11 and the strip-shaped opening 16, that is Figure 4 the area where the springs 17 are located, which can prevent the anti-corrosion paint from splashing into the area where the springs 17 are located when flowing towards the through groove 12.

[0038] Refer to Figures 4 - 6 , the baffle 9 is provided with two sliding grooves 18. A plurality of balls 19 are rotatably connected to the inner top wall of the slotted groove 13. The balls 19 are located inside the sliding grooves 18 and are slidably connected to the sliding grooves 18.

[0039] When the baffle 9 moves inside the slotted groove 13, in order to reduce the friction between the baffle 9 and the connecting head 3, the inner top wall of the slotted groove 13 does not directly contact the baffle 9 through the balls 19. Then, when the baffle 9 moves, the sliding grooves 18 will slide along the balls 19, and at the same time, it also makes the movement of the inner cylinder 7 and the baffle 9 smoother.

[0040] Refer toFigures 1 - 2 On the outer wall of the inner cylinder 7, a slat 5 is fixedly installed. The main body 1 of the air gun is provided with a square slideway 4. The slat 5 extends to the outside of the main body 1 of the air gun through the square slideway 4, and the slat 5 is slidably connected to the square slideway 4.

[0041] Moving the slat 5 along the square slideway 4 by finger can drive the inner cylinder 7 inside the main body 1 of the air gun to move, which is convenient for operation.

[0042] Refer to Figure 2 The outer wall of the inner cylinder 7 abuts against the inner wall of the main body 1 of the air gun. The inner cylinder 7 is provided with a strip-shaped groove 8. The bottom of the baffle 9 is fixedly connected to the inner bottom wall of the strip-shaped groove 8.

[0043] The strip-shaped groove 8 leaves space for the connecting head 3, so that when the inner cylinder 7 moves, the strip-shaped groove 8 will slide along the connecting head 3, preventing the inner cylinder 7 from touching the connecting head 3 and thus being unable to move.

[0044] Refer to Figures 1 - 2 The main body 1 of the air gun is provided with a slot 6. The outer wall of the connecting head 3 is fixedly connected to the inner wall of the slot 6, and the bottom end of the connecting head 3 extends into the strip-shaped groove 8.

[0045] The slot 6 provides space for the connecting head 3 to be inserted into the main body 1 of the air gun. At the same time, the connecting head 3 is fixed in the slot 6, and it does not affect the transmission of the anticorrosive paint by the connecting head 3.

[0046] Working principle:

[0047] First, the steps for the main body 1 of the air gun to eject gas are as follows: The main body 1 of the air gun is connected to an air compressor through a pipeline. Therefore, after the main body 1 of the air gun is started, gas will enter the main body 1 of the air gun. The gas in the main body 1 of the air gun enters the cavity inside the inner cylinder 7 through the air vent 10, and then is sprayed from the air vent 10 at the other end of the inner cylinder 7 to the muzzle of the main body 1 of the air gun, and then is sprayed out from the main body 1 of the air gun.

[0048] Secondly, the anticorrosive paint in the storage barrel 2 enters the main body 1 of the air gun through the connecting head 3. The liquid flows out through the spray holes at the bottom of the spray head 14. The spray holes at the bottom of the spray head 14 abut against the top of the top plate 11. At this time, the anticorrosive paint cannot flow out from the spray holes at the bottom of the spray head 14. When the inner cylinder 7 is moved to the left, the baffle 9 moves together with the inner cylinder 7 until the through groove 12 on the right is moved to correspond to the spray head 14. Then the anticorrosive paint will flow into the through groove 12 through the spray head 14, and finally enter the cavity inside the inner cylinder 7 through the through groove 12. Then the gas will blow the anticorrosive paint in the cavity out of the main body 1 of the air gun and finally spray it on the steel member.

[0049] Before spraying the anti-corrosion paint, move the inner cylinder 7 to the right. At this time, the nozzle 14 is blocked by the top plate 11, and the anti-corrosion paint cannot flow into the cavity of the air gun body 1. Then start the air gun body 1. The air gun body 1 can only eject gas. Since the air compressor can compress air, the gas ejected by the air gun body 1 has an impact force. Then use the high-pressure gas to impact the steel member, thereby achieving the effect of removing the impurity particles on the steel member. After removing the impurity particles, move the inner cylinder 7 again to make the anti-corrosion paint flow into the cavity, and then carry out painting.
