Description

Technical Field

[0001] This utility model relates to the field of paperboard production technology, and in particular to a steam humidification device for electromagnetic heating paperboard production lines. Background Technology

[0002] Five-layer paperboard is often dried using high-efficiency nano-thermal energy (electromagnetic heating) during paperboard production. No steam is generated during the heating process, but because of the difference in moisture content between the paper and the dry areas, the moisture content of the paper must be balanced to ensure the quality of the finished paperboard.

[0003] Therefore, steam is needed to balance the moisture content of paper during production. However, in actual production, after steam is transported through long-distance pipelines, the saturated steam becomes significantly supersaturated due to heat loss. When steam in this state comes into contact with the surface of the cardboard, condensation is easily formed at the contact interface due to the temperature difference, causing abnormally high humidity in local areas. This non-uniform humidification phenomenon not only causes deformation of the paper fiber structure but also affects the quality of the cardboard after production. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that steam is used as a humidification method to balance the moisture of paper during production. However, in actual production, after the steam is transported through long-distance pipelines, the saturated steam will become significantly supersaturated due to heat loss. When the steam in this state comes into contact with the surface of the paperboard, condensation is easily formed at the contact interface due to the temperature difference, causing abnormally high humidity in local areas. This non-uniform humidification phenomenon will not only cause deformation of the paper fiber structure, but also affect the quality of the paperboard after production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steam humidification device for an electromagnetically heated cardboard production line, comprising:

[0006] A base plate, with connecting frames fixedly connected to both ends of the base plate, a turntable rotatably connected inside the connecting frames, and an outer tube fixedly connected between the turntables;

[0007] The inner tube extends through the turntable to the interior of the outer tube, and a separate structure is formed between the inner tube and the outer tube;

[0008] A drain pipe, which is fixedly connected to the lower end of the outer pipe;

[0009] A steam input pipe is fixedly connected to the upper end of the inner pipe;

[0010] An angle adjustment mechanism is provided, wherein a mounting plate is fixedly connected to the side of the base plate away from the inner tube input end, and a mounting platform is fixedly connected to the side end of the mounting plate. The angle adjustment mechanism is disposed in the mounting platform and is connected to the turntable transmission.

[0011] In a preferred embodiment, the separation structure is as follows: the lower end of the inner tube is provided with a plurality of uniformly distributed first steam outlets, and the top end of the outer tube is provided with a plurality of uniformly distributed second steam outlets, the second steam outlets being arranged opposite to the first steam outlets.

[0012] In a preferred embodiment, a threaded rod is rotatably connected inside the mounting platform, and a connecting block is threaded onto the threaded rod.

[0013] In a preferred embodiment, the angle adjustment mechanism includes a second connecting pin fixedly connected to the end of the connecting block, a first connecting pin fixedly connected to the end of the turntable, and the two ends of the connecting rod rotatably connected to the first connecting pin and the second connecting pin, respectively.

[0014] In a preferred embodiment, a throttle is fixedly connected to the top end of the threaded rod.

[0015] In a preferred embodiment, a guide rod is fixedly connected inside the mounting platform, and the guide rod is slidably connected to the connecting block.

[0016] In a preferred embodiment, a second connecting flange is fixedly connected to the lower end of the drain pipe.

[0017] In a preferred embodiment, a first connecting flange is fixedly connected to the top end of the steam input pipe.

[0018] In a preferred embodiment, a sliding seal is provided at the contact point between the outer pipe and the first steam outlet.

[0019] In a preferred embodiment, support pads are fixedly connected to the four corners of the bottom of the base plate.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] This invention can separate steam with low moisture content from steam with high moisture content. The steam with high moisture content condenses at the point of contact with the outer tube before it approaches, and the resulting condensate is discharged through the drain pipe. The steam with low moisture content contacts the cardboard through the second steam outlet. Because of its relatively low moisture content, it will not condense with the cardboard. The discharged steam can also prevent condensate from affecting the cardboard during normal humidification, thus preventing uneven humidification and improving the quality of cardboard production.

[0022] 2. In this utility model, the up-and-down movement of the connecting block can drive the connecting rod to change its angle, which, together with the first connecting pin, drives the turntable to rotate, thereby controlling the angle of the outer cylinder and the steam ejection angle, thus improving the flexibility of the device.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-3 This utility model provides a technical solution: a steam humidification device for an electromagnetically heated cardboard production line, comprising:

[0030] A base plate 1, with connecting frames 3 fixedly connected to both ends of the base plate 1, a turntable 10 rotatably connected inside the connecting frame 3, and an outer tube 9 fixedly connected between the turntables 10;

[0031] Drain pipe 7 is fixedly connected to the lower end of outer pipe 9;

[0032] Steam input pipe 5 is fixedly connected to the upper end of inner pipe 4;

[0033] Inner tube 4 penetrates the turntable 10 to the interior of outer tube 9, and a separation structure is formed between inner tube 4 and outer tube 9;

[0034] The separation structure is as follows: the lower end of the inner tube 4 is provided with multiple evenly distributed first steam outlets 21, and the top end of the outer tube 9 is provided with multiple evenly distributed second steam outlets 11, with the second steam outlets 11 and the first steam outlets 21 being distributed opposite to each other.

[0035] Supporting feet 2 are fixedly connected to the four corners of the bottom of the base plate 1. The supporting feet 2 serve to provide stable support for the device.

[0036] The specific principle of the above separation structure is explained in detail below: After steam enters the inner tube 4 through the steam input pipe 5, it is output through the first steam outlet 21 at the lower end of the inner tube 4. At this time, the output steam needs to overcome gravity to be output through the second steam outlet 11 to humidify the cardboard. However, the steam with higher water content has a larger mass and does more work to overcome gravity. The distance between the first steam outlet 21 and the second steam outlet 11 allows the steam with higher water content to be located below the steam with lower water content, thereby separating the steam with lower water content from the steam with higher water content. The steam with higher water content condenses at the contact point with the outer tube 9 after approaching it, and the condensate is discharged through the drain pipe 7. The steam with lower water content contacts the cardboard through the second steam outlet 11. Since the water content is relatively small, it will not condense with the cardboard. In this application, during the normal humidification of the cardboard, the condensate can also prevent the cardboard from being affected by the condensate.

[0037] The lower end of the drain pipe 7 is fixedly connected to a second connecting flange 8, and the top end of the steam input pipe 5 is fixedly connected to a first connecting flange 6. The first connecting flange 6 and the second connecting flange 8 facilitate the connection of the device to external pipelines.

[0038] An angle adjustment mechanism is provided. A mounting plate 12 is fixedly connected to the side of the base plate 1 away from the input end of the inner tube 4. A mounting platform 19 is fixedly connected to the side end of the mounting plate 12. The angle adjustment mechanism is set in the mounting platform 19 and is connected to the turntable 10 for transmission. A threaded rod 18 is rotatably connected in the mounting platform 19. A connecting block 16 is threadedly connected to the threaded rod 18.

[0039] A sliding seal is provided at the contact point between the outer tube 9 and the first steam outlet 21 to prevent heat loss from the outer tube 9 when the rotating disk 10 rotates.

[0040] A guide rod 17 is fixedly connected inside the mounting platform 19. The guide rod 17 is slidably connected to the connecting block 16. The guide rod 17 and the connecting block 16 cooperate to guide and limit the movement of the connecting block 16.

[0041] A handle 20 is fixedly connected to the top of the threaded rod 18 to facilitate the rotation drive of the threaded rod 18;

[0042] The guide limit of the moving connecting block 16, combined with the rotation of the threaded rod 18, can drive the connecting block 16 to move radially along the threaded rod 18;

[0043] The angle adjustment mechanism includes a second connecting pin 15 fixedly connected to the end of the connecting block 16, a first connecting pin 14 fixedly connected to the end of the turntable 10, and a connecting rod 13 provided between the first connecting pin 14 and the second connecting pin 15. The two ends of the connecting rod 13 are rotatably connected to the first connecting pin 14 and the second connecting pin 15, respectively.

[0044] The specific principle of the above-mentioned angle adjustment mechanism is as follows: by moving the connecting block 16 up and down, the connecting rod 13 can be driven to change its angle, which, together with the first connecting pin 14, drives the turntable 10 to rotate, thereby controlling the angle of the outer cylinder 9 and controlling the steam ejection angle, thus improving the flexibility of the device.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
