Description

Technical Field

[0001] The utility model belongs to the technical field of pipe galvanizing processing and application, and particularly relates to a drying device used for producing galvanized pipes. Background Art

[0002] Currently, galvanized steel pipes are usually hot-dip galvanized steel pipes, which are welded steel pipes with a hot-dip or electroplated zinc layer on the surface.

[0003] Hot-dip galvanizing involves first pickling steel pipes to remove iron oxide from their surfaces. After pickling, the steel pipes are rinsed in an aqueous solution of ammonium chloride, zinc chloride, or a mixture of ammonium chloride and zinc chloride before being hot-dip galvanized. Hot-dip galvanizing increases the corrosion resistance of steel pipes and extends their service life.

[0004] Before the hot-dip galvanizing process, the pipe body must be pickled and cleaned with a mixed water solution. Before the above cleaning, the pipe body must be polished to achieve high-quality hot-dip galvanizing. The pipe body after the surface polishing is usually rinsed (with water) to remove the residual particles and debris on the polished surface. In order to achieve a fast hot-dip galvanizing process for the pipe body, the pipe body needs to be dried after the conventional rinse (with water).

[0005] How to quickly dry the inner / outer wall surface of the pipe body is a problem that needs to be studied and solved.

[0006] Therefore, based on the above problems, the present invention provides a drying device for producing galvanized pipes. Utility Model Content

[0023] A horizontal support plate 200 is symmetrically arranged on the horizontal base 100.

[0024] A drying shell 201 is provided on the horizontal support plate 200.

[0025] A horizontal cavity 202 is provided inside the drying shell 201.

[0026] A sealing plate 204 is provided on one end surface of the drying shell 201.

[0027] The sealing plate 204 is provided with a heating portion mounting groove 207.

[0028] A heating unit seat 208 is provided on the sealing plate 204 through the heating unit mounting groove 207.

[0029] A heating portion 210 (heating rod) is provided on one side of the heating portion seat 208 and is located in the transverse cavity 202.

[0030] The other side of the heating portion seat 208 is provided with a plug 209 with a conductive wire.

[0031] Several air inlet holes 212 are evenly distributed in the upper part of the drying shell 201.

In this way, the explosion-proof hot air blower 101 performs hot air drying on the outer wall of the pipe body 300 through the air duct 102, the air duct flange plate 103, the air distribution shell 213 and several air inlet holes 212. The heating part seat 208 is connected to an external power supply through a conductive wire plug 209, and uses the heating part 210 to perform high-temperature drying on the inside of the pipe body 300.

[0034] Example 2

[0035] Based on the first embodiment, the drying device for producing galvanized pipes further includes a water collecting bucket 211 provided at the lower portion of the horizontal base 100, an arc-shaped water collecting concave surface 218 provided in the drying shell 201 and located below the horizontal cavity 202, a vertical water inlet 219 provided in the drying shell 201 and used in conjunction with the arc-shaped water collecting concave surface 218, and a flange plate 220 with a hose connected to the vertical water inlet 219;

[0042] In addition, the preferred plurality of air inlet holes 212 are evenly distributed in a "straight line" in the upper part of the drying shell 201, which is suitable for blowing hot air to the outer wall of the inserted pipe body 300 to accelerate evaporation and drying; the air distribution shell 213 is set as an open rectangular structure to achieve balanced air distribution of the plurality of "straight line" air inlet holes 212.

[0043] In addition, in actual application: (1) this structure can be used with an industrial robot, which clamps one end of the pipe body 300 and inserts it horizontally into the transverse cavity 202. At the same time, during the inner / outer wall drying operation, the pipe body 300 can be controlled to rotate to complete the hot air drying at different positions of the outer wall; (2) The opening size of the transverse cavity 202 is 20-30 cm, and the length dimension is greater than the length dimension of the pre-dried pipe body 300, while the length dimension of the heating part 210 is equal to or less than the length dimension of the pre-dried pipe body 300, and the "I-shaped" multiple air inlet holes 212 cover the outer wall surface of the pre-dried pipe body 300 (the length dimension of the "I-shaped" multiple air inlet holes 212 is greater than the length dimension of the pre-dried pipe body 300).

[0044] The structural principle or working principle of the drying device for galvanized pipe production of this structure:

[0045] First, the explosion-proof hot air blower 101 is started. The explosion-proof hot air blower 101 blows dry hot air into the transverse cavity 202 through the air duct 102, the air duct flange plate 103, the air distribution housing 213, and the plurality of air inlet holes 212. The hot air blower 101 is connected to the power supply via the conductive plug 209 and heats the transverse cavity 202 using the heating portion 208.

[0046] Then, the polished and rinsed pipe body 300 is horizontally inserted into the transverse cavity 202. At this time, the heating unit 210 is located inside the pipe body 300 to dry the inner wall (the heating unit 210 does not contact the inner wall of the pipe body 300). The explosion-proof hot air blower 101 uses hot air to dry the outer wall of the pipe body 300 through the air duct 102, the air duct flange plate 103, the air distribution shell 213 and the plurality of air inlet holes 212.

[0047] Finally, after drying is completed, the horizontal part is removed and inserted into the transverse cavity 202.

[0048] Figure 1 The dark arrows in the middle represent the flow direction of water attached to the outer wall surface of the pipe body 300, and the dark arrows represent the flow direction of hot air; Figure 2 The double single arrows in the middle represent the horizontal movement direction of the tube body 300 into / out of the transverse cavity 202 .
