DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1 、 Figure 2 as well as Figure 3As shown, a clean papermaking steam circulation device includes an overall frame 1, a roller 2, a first pipe 4, a second pipe 5, a water tank 6, a pumping device 9, a water pump 11 and a steam engine 12; the roller 2 is arranged inside the overall frame 1, and bearings 3 are arranged on both sides of the roller 2. The center point of the roller 2 and the bearing 3 is penetrated by the first pipe 4, and the end extending into the interior of the roller 2 is sealed and connected, and a plurality of first spray holes 7 are provided on the first pipe 4; the other end of the first pipe 4 is connected to the steam outlet end of the steam engine 12; the water inlet of the steam engine 12 is connected to the third pipe 8, the water pump 11 is arranged in the middle of the third pipe 8, and the third pipe 8 is provided with a plurality of first spray holes 7. 8 is connected to the water pumping port of the water tank 6; the water tank 6 is provided with the water pumping device 9, and the water pumping device 9 includes an electric push-pull device 91 and a water storage cavity 93; an opening 96 is provided at one end of the water storage cavity 93, and the electric push-pull device 91 passes through the opening 96 and is fixedly connected to a sealing plate 92, and the sealing plate 92 is inside the water storage cavity 93; a water inlet 94 is provided at the other end of the water storage cavity 93, and the water outlet 95 is provided below the water storage cavity 93; the water inlet 94 is connected to the second pipe 5, and the second pipe 5 passes through and is connected to the first pipe 4, and the second pipe 5 extends along the first pipe 4 to the bottom of the inner side of the roller 2. Specifically, the first pipe 4 also passes through the overall frame 1. At the same time, the second pipe 5 passes through the bearing 3 inside the first pipe 4 and extends downward along the center point of the bearing 3 to the bottom of the roller 2. A distance of 0.3cm-0.8cm is left at the bottom to prevent the second pipe 5 from being driven by the roller 2 when it rotates. The electric push rod device 91 is a common push rod device that can be purchased at hardware stores and major online shopping platforms. The electric push rod device 91 can be remotely controlled to push and pull, and a time setting, such as pushing and pulling once every 30 minutes, can even be controlled by a mobile phone. In short, it is very convenient to use. When in use, the circular hole in the middle of the right side of the water tank 6 is a normally open water injection hole. When closed, it can also be closed with a plug. After water is added, the water pump 11 draws out the water in the water tank 6 and transports it to the steam engine 12. The steam engine 12 outputs steam, and the steam is transported along the first pipe 4 to the spray hole 7. The spray hole 7 sprays the steam into the interior of the roller 2. The roller 2 generates heat to heat the roller, thereby drying the paper. The above drying process generates a large amount of condensed water within the roller 2. Since the roller 2 is cylindrical, the condensed water will remain at the bottom of the roller 2 when the roller 2 rotates. At this time, the electric push-pull device 91 is activated. As long as the pumping device 9 is lower than the water level, the condensed water is sucked into the second pipe 5 by air pressure. The condensed water flows along the second pipe 5 into the water storage cavity 93 and finally flows into the water tank 6 through the water outlet 95, so that the condensed water can be discharged into the water tank 6 when the roller 2 rotates. The electric push rod device 91 is preferably equipped with a timing function. Those skilled in the art can make a rough judgment based on the time it takes for steam to be delivered to the interior of the roller 2 and the specific amount of condensed water generated, and set the time.When the electric push rod device 91 is pushed back, the condensed water has been drained away, and a small amount of air will be pushed into the roller 2. Those skilled in the art will know that this will not cause any impact and the air pressure will not be too high, after all, the steam is continuously transported to the inside of the roller 2.

[0032] In an exemplary embodiment, Figure 2 As shown, a partition 62 is fixedly installed inside the water tank 6; the partition 62 divides the water tank 6 into a placement chamber 61 at the upper end and a water storage chamber 63 at the lower end; the pumping device 9 is arranged inside the placement chamber 61; a through hole 64 is provided on the partition 62, and the water outlet 95 extends through the through hole 64 to the inside of the water storage chamber 63. Specifically, the water tank 6 is divided into two layers, the upper layer, and the baffle on the left side of the placement chamber 61 is detachable to facilitate inspection of the pumping device; the electric push-pull device 91 is fixed to one side of the placement chamber 61, and the water outlet 95 is snapped into the first through hole 64, which can make the pumping device 9 more stable and firm, and can also reduce shaking when the condensed water flows into the water storage chamber 63. According to actual needs, the partition 62 can be set to tilt to the left to allow the condensed water to enter the water storage chamber 63 more smoothly through the water outlet 95.

[0033] In an exemplary embodiment, Figure 2 as well as Figure 4 As shown, a convex plate 10 is provided below the overall frame 1, and the convex plate 10 is lower on the left and higher on the right, and is tilted. When in use, the convex plate 10 is tilted, which allows condensed water to enter the water storage cavity 93 more quickly, thereby flowing into the water storage chamber 63.

[0034] In an exemplary embodiment, Figure 2 As shown, the roller 2 includes a first sleeve 21 and a second sleeve 22. The first sleeve 21 is rotatably connected to the bearing 3, while the second sleeve 22 is fixedly connected to the first pipe 5. The second sleeve 22 is provided with a plurality of second spray holes 15, each corresponding to the first spray holes 7. The second spray holes 15 and the first spray holes 7 are connected to the sleeve 13. Specifically, the first pipe 4 and the second sleeve 22 fixed to the first pipe 4 are both fixed and non-rotatable. The second spray holes 15 and the first spray holes 7 are fixedly connected and sealed by the sleeve 13, making the chamber within the second sleeve 22 sealed and preventing water vapor from flowing into the chamber within the second sleeve 22. During operation, steam enters the first pipe 4, passes through the sleeve 13, and flows into the chamber between the second sleeve 22 and the first sleeve 21, reducing the space. When the steam input into the roller 2 is the same, the smaller the space, the faster the heat transfer to the first sleeve 21. Furthermore, if the temperature outside the first sleeve 21 needs to remain the same, the less steam input is needed.

[0035] In an exemplary embodiment, Figure 2 as well as Figure 5 As shown, a nozzle 14 is fixedly provided outside the second spray hole 15. When in use, the nozzle 14 is a part of a spherical spray hole surface, and the spray holes are closely connected, which does not affect the spraying of steam and can make the heating surface of the steam larger when spraying through the nozzle 14.

[0036] In an exemplary embodiment, Figure 2 As shown, the diameter of the first pipe 4 is 5cm-20cm, and the diameter of the second pipe 5 is 0.8cm-2cm. In use, the shorter the diameter of the second pipe 5, the smaller the steam will be blocked. However, if it is too small, the pipe will be slightly deformed. Preferably, a second pipe 5 with a diameter of 1cm is used. The first pipe 4 is determined according to the steam exhaust volume of the steam engine. If the diameter of the first pipe 4 is too long, the steam will diffuse and the delivery speed will be slow. Preferably, the first pipe 4 has a diameter of 10cm.

[0037] In an exemplary embodiment, Figure 3 As shown, the diameter of the water storage cavity 93 is 10-25 cm. When in use, the second pipe 5 is connected to the water inlet 94 on the pumping device 9. Since the pumped water is pressurized, the flow rate of the water flowing into the water inlet 94 is faster than the flow rate of the water flowing out of the water outlet 95. Therefore, it is necessary to provide a sufficient water storage cavity 93. The specific amount of water storage cavity 93 is determined by the length and diameter of the second pipe 5 during use.

[0038] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present embodiments. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present embodiments. Therefore, the present embodiments are not limited to the embodiments shown herein, but are intended to be implemented in the widest possible manner consistent with the principles and novel features disclosed herein.
