These parts work together to ensure that the square tubes can be subjected to efficient and stable hot-dip galvanizing treatment to obtain excellent corrosion resistance and service life;

[0003] When the square rectangular tube is galvanized, since the reaction liquid stored in the box is in a static state, the internal temperature will be uneven or the ion concentration will be different, which will affect the galvanizing effect of the square rectangular tube. When the square rectangular tube is galvanized, the square rectangular tube will react with the reaction liquid to produce harmful gases. However, when the square rectangular tube is galvanized, the gases produced during the reaction are not treated, which not only pollutes the environment, but also has a greater irritation to the human respiratory tract. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: Figure 1-4 As shown, the utility model provides a square tube hot-dip galvanizing device, including a box body 1, a first rotating shaft 23 is rotatably installed on one side of the lower part of the box body 1, one side of the first rotating shaft 23 passes through the box body 1, and a second bevel gear 22 is fixedly installed on one end of the first rotating shaft 23 passing through the box body 1, and a plurality of first stirring rods 231 distributed at equal intervals are fixedly installed on the outer surface of the first rotating shaft 23, a third bevel gear 24 is provided on one side of the second bevel gear 22, a second rotating shaft 25 is fixedly installed in the middle of one side of the third bevel gear 24, the second rotating shaft 25 passes through the middle of the second bevel gear 22, one side of the second rotating shaft 25 is slidably inserted in the middle of the first rotating shaft 23, and a plurality of second stirring rods 251 distributed at equal intervals are fixedly installed on the outer surface of one side of the second rotating shaft 25, and a driving component is provided at the lower part of one side of the box body 1.

[0018] A second motor 3 is provided on one side of the upper portion of the housing 1, a first gear 31 is provided on one side of the second motor 3, two diagonally distributed tooth plates 32 are provided on one side of the housing 1, both tooth plates 32 are meshed and connected with the first gear 31, baffles 33 are fixedly installed on one side of the two tooth plates 32, sliders 34 are fixedly installed on one side of the two baffles 33, an exhaust gas treatment device 4 is provided on one side of the housing 1, and an input end of the exhaust gas treatment device 4 is fixedly installed on an upper portion of one side of the housing 1.

[0019] The driving assembly includes a first motor 2, which is installed at the lower part of one side of the housing 1. A first bevel gear 21 is provided at the upper part of the first motor 2. The bottom end of the first bevel gear 21 is fixedly installed at the driving end of the first motor 2. The first bevel gear 21 is meshed and connected with the second bevel gear 22 and the third bevel gear 24. By setting the first motor 2 and starting the first motor 2, the first bevel gear 21 is driven to rotate, so that the second bevel gear 22 and the third bevel gear 24 are rotated, that is, the first rotating shaft 23 and the second rotating shaft 25 are rotated, so that the rotation of the first rotating shaft 23 and the second rotating shaft 25 drives the first stirring rod 231 and the second stirring rod 251 to rotate, thereby stirring the internal reaction liquid.

[0020] A fixing block 11 is fixedly installed on the lower part of one side of the box body 1, and one side of the third bevel gear 24 is rotatably installed on the side of the fixing block 11. The driving end of the first motor 2 passes through the lower part of the fixing block 11. By setting the fixing block 11 and rotatably installing the third bevel gear 24 on one side of the fixing block 11, when the third bevel gear 24 rotates, it drives the second rotating shaft 25 to rotate more stably.

[0021] Two sets of symmetrically distributed third stirring rods 26 are fixedly installed inside the box 1. By setting the third stirring rods 26, the third stirring rods 26 cooperate with the first stirring rods 231 and the second stirring rods 251, so that the reaction liquid inside the box 1 can be stirred more fully.

[0022] Two symmetrically distributed slide grooves 321 are provided on one side of the upper part of the box body 1, and the two tooth plates 32 are slidably clamped inside the slide grooves 321. By setting the slide grooves 321 and sliding the tooth plates 32 inside the slide grooves 321, the tooth plates 32 are driven to move more stably when the first gear 31 rotates.

[0023] Two diagonally distributed limiting grooves 341 are provided on one side of the box body 1 close to the slider 34. Both sliders 34 are slidably clamped in the limiting grooves 341. By setting the limiting grooves 341, the slider 34 fixedly installed on one side of the baffle 33 is limited by the limiting grooves 341, so that the baffle 33 is more stable when moving.

[0024] A fixing plate 35 is fixedly installed on the upper part of one side of the box body 1, and the bottom end of the second motor 3 is fixedly installed on the middle of the top end of the fixing plate 35. By setting the fixing plate 35, the second motor 3 is fixedly installed on the upper part of the fixing plate 35, thereby fixing the second motor 3.

[0025] Working principle: In actual use, by starting the first motor 2, the first bevel gear 21 is driven to rotate, so that the second bevel gear 22 and the third bevel gear 24 are rotated, that is, the first rotating shaft 23 and the second rotating shaft 25 are rotated. Since the second bevel gear 22 and the third bevel gear 24 are distributed in a mirror image, the rotation directions of the first rotating shaft 23 and the second rotating shaft 25 are opposite, thereby driving the first stirring rod 231 and the second stirring rod 251 to rotate in opposite directions, thereby stirring the reaction liquid inside;

[0026] The square tube is placed in the box 1 and galvanized. At the same time, the second motor 3 is started to drive the first gear 31 to rotate, so that the tooth plate 32 moves under the limit of the slide groove 321. Since the two tooth plates 32 are diagonally distributed, they move relative to or away from each other during movement, thereby driving the two baffles 33 to move, that is, the upper part of the box 1 is closed, and the exhaust gas treatment device 4 is started. The gas generated when the square tube reacts with the reaction liquid during galvanizing is sucked in by the exhaust gas treatment device 4 to treat the harmful gas. After the galvanizing is completed, the two baffles 33 can be opened by reverse operation to take out the galvanized square tube.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
