Detailed Description of the Invention

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] A drying device for special-shaped steel, as Figure 1-6 shown, includes an electric conveyor belt 1 and positioning rollers 2; several positioning rollers 2 are rotatably connected to the upper side of the electric conveyor belt 1, and the positioning rollers 2 are made of alloy material; it also includes a scraper 3, a heating component and a water absorption component; a heating component for heating the special-shaped steel body 4 is connected to the middle of the electric conveyor belt 1; a scraper 3 is connected to the heating component; the scraper 3 is used to scrape off the clear water on the special-shaped steel body 4; a water absorption component is connected to the scraper 3; the water absorption component is used to absorb the clear water accumulated beside the scraper 3.

[0033] The heating component includes a housing 201, side plates 202, heating strips 203 and a first pipe 204; the housing 201 is bolted to the outside of the electric conveyor belt 1; the housing 201 is connected to the scraper 3; a side plate 202 is bolted to both ends of the housing 201; eight heating strips 203 are fixedly connected to the inner side of the housing 201, and the surface of the special-shaped steel body 4 is heated by the heating strips 203 to achieve the drying effect; three first pipes 204 are communicated with the housing 201.

[0034] The water absorption component includes an air pump 205, a second pipe 206, a cylinder 207, a third pipe 208, a solenoid valve 209, a fourth pipe 2010 and a fifth pipe 2011; the air pump 205 is bolted to the scraper 3; the input end of the air pump 205 is communicated with the second pipe 206, and the second pipe 206 can be set as a flexible pipe or a rigid pipe; the cylinder 207 is bolted to the scraper 3; the cylinder 207 is communicated with the second pipe 206; the lower side of the cylinder 207 is communicated and screwed with the third pipe 208; a solenoid valve 209 is installed on the third pipe 208; the upper side of the cylinder 207 is communicated and screwed with the fourth pipe 2010; several fifth pipes 2011 are communicated and welded to the fourth pipe 2010, and the fifth pipes 2011 pass through the scraper 3; the arrangement density of the fifth pipes 2011 located below the fourth pipe 2010 is greater than that of the fifth pipes 2011 located above; the clear water accumulated on the left side of the scraper 3 is absorbed through the fifth pipes 2011.

[0035] The water absorption assembly further includes a U-shaped strip 2012; the U-shaped strip 2012 is welded to the squeegee 3, and the U-shaped strip 2012 is used to block and limit the clear water, which is beneficial to improving the water absorption efficiency of the fifth pipeline 2011 for the clear water.

[0036] The water absorption assembly further includes a first rubber ring 2013; the first rubber ring 2013 is fixedly connected to the outer side of the squeegee 3.

[0037] First, manually connect the external exhaust pipe to the first pipeline 204, connect the external drain pipe to the third pipeline 208, the electric conveyor belt 1 drives the profiled steel body 4 to move to the right, so that the right end of the profiled steel body 4 penetrates into the housing 201 and contacts the first rubber ring 2013. The profiled steel body 4 continues to move to the right, so that the first rubber ring 2013 slides relative to the profiled steel body 4. The first rubber ring 2013 and the squeegee 3 block and limit the clear water inside the profiled steel body 4, so that the clear water accumulates on the left side of the first rubber ring 2013 and the squeegee 3 and contacts the end of the fifth pipeline 2011. Start the air pump 205, and the air pump 205 sucks air into the second pipeline 206. The second pipeline 206 sucks air into the cylinder 207, so that the cylinder 207 is in a negative pressure state. As a result, the clear water accumulated on the left side of the first rubber ring 2013 and the squeegee 3 sequentially flows into the cylinder 207 through the fifth pipeline 2011 and the fourth pipeline 2010. That is, after the right end of the profiled steel body 4 passes through the first rubber ring 2013 and the squeegee 3, the clear water inside it has been sucked out. The heating strip 203 starts to generate heat by itself and heats the outer surface of the profiled steel body 4, so that the moisture on the outer surface of the profiled steel body 4 is converted into water vapor. The water vapor floats up and flows into the external exhaust pipe through the first pipeline 204, completing the drying operation of the profiled steel body 4. After that, open the solenoid valve 209, so that the clear water in the cylinder 207 flows into the external drain pipe through the third pipeline 208. When in use, through the cooperation of the squeegee 3, the fifth pipeline 2011 and the first rubber ring 2013, the clear water remaining in the profiled steel body 4 is cleaned up, and then the drying operation is carried out, solving the problem of insufficient drying caused by excessive residual clear water in the prior art. And the first rubber ring 2013 can adaptively deform according to the concave and convex conditions of the inner side of the profiled steel body 4, which is beneficial to improving the clear water removal efficiency.

[0038] During the process of the fifth pipeline 2011 sucking clear water, by arranging a U-shaped strip 2012 on the left side of the scraper 3, a relatively narrow groove 91 is jointly formed between the outer side of the scraper 3 and the inner surface of the 4-profile steel. When the scraper 3 and the first rubber ring 2013 block and limit the clear water, the clear water first fills into the groove 91, and then the clear water in the groove 91 is sucked out through the fifth pipeline 2011, which makes it easier for the clear water to cover the port of the fifth pipeline 2011, thereby improving the sucking efficiency of the fifth pipeline 2011 for clear water. At the same time, under the action of the gravity of the clear water itself, more clear water will gather at the lower left part of the scraper 3. At this time, by arranging more dense fifth pipelines 2011 at the lower part, the sucking efficiency of the clear water at the lower left part of the scraper 3 is enhanced, and the sucking efficiency is further improved.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, as Figure 1-2 and Figure 7-8 shown, it further includes an auxiliary component; an auxiliary component is connected to the fourth pipeline 2010; the auxiliary component includes a connecting frame 2014 and a first water-absorbing member 2015; the connecting frame 2014 is fixedly connected to the fourth pipeline 2010, and the connecting frame 2014 is made of alloy material; the first water-absorbing member 2015 is fixedly connected to the connecting frame 2014, and the first water-absorbing member 2015 is made of sponge material, and the clear water in the depression of the profile steel body 4 is sucked out through the first water-absorbing member 2015.

[0041] It further includes a second water-absorbing member 2016; the second water-absorbing member 2016 is fixedly connected to the first water-absorbing member 2015, and the second water-absorbing member 2016 is fixedly connected to the scraper 3, and the volatilization speed of the clear water on the first water-absorbing member 2015 is accelerated through the second water-absorbing member 2016.

[0042] It further includes a water removal component; a water removal component is connected to the air pump 205; the water removal component includes a sixth pipeline 2017 and an air dryer 2018; the output end of the air pump 205 is communicated and screwed with the sixth pipeline 2017; the lower port of the sixth pipeline 2017 is located in the cavity 92; the sixth pipeline 2017 is communicated with the inside of the housing 201; an air dryer 2018 is installed on the second pipeline 206.

[0043] It further includes a third water-absorbing member 2019; seven third water-absorbing members 2019 are fixedly connected to the side of the second water-absorbing member 2016 close to the scraper 3, and the volatilization speed of the clear water on the second water-absorbing member 2016 is accelerated through the third water-absorbing members 2019.

[0044] During the forming process of the special-shaped steel body 4, due to defects in the process and materials, the surface of the special-shaped steel body 4 is uneven, resulting in small depressions or protrusions on the surface of the special-shaped steel body 4. The clear water in the depression on the inner vertical surface of the special-shaped steel body 4 falls to the bottom of the inner side of the special-shaped steel body 4 due to gravity. When the depression degree at the bottom of the inner side of the special-shaped steel body 4 is relatively large, the first rubber ring 2013 cannot block the clear water in the depression, resulting in the phenomenon of clear water residue, which affects the drying operation. At this time, the first water-absorbing member 2015 is squeezed by the connecting frame 2014 to the bottom of the inner side of the special-shaped steel body 4. When the depression of the special-shaped steel body 4 moves below the first water-absorbing member 2015, the first water-absorbing member 2015 made of sponge material rebounds into the depression and absorbs the remaining clear water, avoiding the problem of insufficient drying caused by the excessive depression degree at the bottom of the inner side of the special-shaped steel body 4.

[0045] The clear water absorbed by the first water-absorbing member 2015 is automatically transferred to the dry second water-absorbing member 2016 due to negative pressure. During the process of the fifth pipe 2011 sucking clear water, part of the air will also enter the fifth pipe 2011, then flow into the cylinder 207 through the fourth pipe 2010, and then flow into the air pump 205 through the second pipe 206. During this process, the air is dried by the air dryer 2018. The dried air flows into the air pump 205, then flows from the air pump 205 into the sixth pipe 2017, and then flows from the sixth pipe 2017 into the cavity 92 to air-dry the second water-absorbing member 2016, thereby air-drying and removing the clear water absorbed by the first water-absorbing member 2015. Moreover, the third water-absorbing member 2019 is used to increase the contact area with the air, which is conducive to improving the air-drying effect. When in use, the air flow generated by the air pump 205 sucking clear water is used to air-dry the first water-absorbing member 2015, and through the cooperation of the second water-absorbing member 2016 and the third water-absorbing member 2019, the contact area with the air is increased, which is beneficial to improving the air-drying effect.

[0047] On the basis of Embodiment 2, as Figure 1-2 and Figure 9-10 shown, it further includes an isolation component; an isolation component is connected to the outer shell 201; the isolation component includes a partition plate 2020 and a second rubber ring 2021; the partition plate 2020 is fixedly connected to the outer shell 201, the partition plate 2020 is fixedly connected to the scraper 3, and the partition plate 2020 is made of alloy material; the second rubber ring 2021 is fixedly connected to the inner side of the partition plate 2020.

[0048] During the process of the fifth pipeline 2011 sucking in clear water, some air will also enter the fifth pipeline 2011, that is, the outside air will enter the inside of the housing 201 from the left side of the housing 201, resulting in a decrease in the temperature inside the housing 201, and further leading to a decrease in the drying efficiency. At this time, through the cooperation of the partition plate 2020 and the second rubber ring 2021, the left part of the housing 201 is partitioned to prevent air from flowing into the right part of the housing 201, thus avoiding the problem of reduced drying efficiency caused by air entering the housing 201. Moreover, the second rubber ring 2021 can adaptively deform according to the concave and convex conditions of the outer side surface of the profiled steel body 4, which is beneficial to improving the partition effect.
