Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, and in particular to a steam heating device for corrugated paper. Background Technology

[0002] Corrugated paper is a multi-layered composite paper material made by bonding corrugated core paper (a paper with a wavy structure) with face paper and liner paper (flat sheets) using adhesives.

[0003] In the production and processing of corrugated paper, heat treatment is a key step to ensure the quality and performance of corrugated paper. The fiber structure of corrugated paper is quite sensitive to temperature and humidity. If the heating is uneven or the humidity is not properly controlled, it can easily lead to problems such as warping, cracking, and reduced strength of the paper, which directly affects the efficiency of subsequent processing and the quality of the finished product.

[0004] Currently, most corrugated paper heating devices used in the industry employ either hot roller contact heating or hot air circulation heating. While hot roller contact heating can achieve continuous heating, the surface temperature of the hot roller is easily affected by environmental factors and fluctuates. Furthermore, uneven contact pressure with the paper can lead to localized overheating or insufficient heating, especially for corrugated paper with uneven thickness, making it difficult to ensure overall heating consistency. Hot air circulation heating, on the other hand, suffers from significant heat loss and low energy utilization. A large amount of high-temperature steam is directly emitted without sufficient contact with the paper, resulting in energy waste and affecting the production environment due to steam permeating the workshop, increasing the risk of equipment corrosion. Therefore, a steam heating device for corrugated paper is needed. Utility Model Content

[0005] The main objective of this invention is to provide a steam heating device for corrugated paper, which can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The inner surface of the steam outlet cylinder is provided with a plurality of sealing rings, which are arranged in pairs for limiting and sealing the steam outlet cylinders.

[0009] Preferably, each of the steam outlet cylinders is provided with a steam outlet that communicates with a circular hole.

A fan for driving is provided on the left side of the cylindrical cylinder. Water supply pipes are symmetrically arranged on the upper and lower sides of the cylindrical cylinder surface, and a spiral pipe is provided between the two water supply pipes. A liquid storage cylinder is provided on the lower side of the cylindrical cylinder surface.

[0013] Preferably, the lower side of the inner surface of the cylindrical cylinder has a through hole communicating with the liquid storage cylinder, and the surface of the liquid storage cylinder has a liquid level line.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through the design of the steam heating component, directly injects steam onto the surface of the corrugated paper via the steam supply pipe, steam outlet, and circular holes on the surface of the steam cylinder, achieving full contact between the steam and the corrugated paper. By adopting the direct steam injection method, the surface temperature and humidity of the corrugated paper can be kept consistent, avoiding defects such as warping and cracking of the corrugated paper, improving the forming quality and structural strength of the corrugated paper, and is especially suitable for corrugated paper processing scenarios with uneven thickness.

[0016] 2. This utility model, through the cooperation of the steam absorption component and the condensation mechanism, can efficiently recover the excess steam remaining after the corrugated paper is heated.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1 and Figure 2 As shown, a corrugated paper steam heating device includes two fixed plates 4, two steam cylinders 1 are provided between the two fixed plates 4, and several friction rings 3 for conveying corrugated paper are provided on the surface of each steam cylinder 1. Several circular holes 2 for steam outlet are opened on the surface of each steam cylinder 1. A steam absorption component 5 for steam recovery is provided in front of the two fixed plates 4. A steam heating component 6 for heating corrugated paper is provided inside each steam cylinder 1. A steam inlet 7 for conveying steam is provided on the left side of each steam heating component 6.

[0026] This device is a heating roller required for steam heating of corrugated paper. In actual use, the device needs to be installed on the relevant heating equipment. The specific installation method is the conventional operation in the existing technology, and will not be described in detail in this article.

[0027] In the above, the driving element of the steam cylinder 1 is installed on the fixed plate 4 on the side away from the steam inlet 7, driving the two steam cylinders 1 to rotate relative to each other. The driving element is driven by a stepper motor.

[0028] The implementation process of this device is as follows:

[0029] After the device is installed on the relevant equipment, the staff connects the steam generator to the steam inlet 7. The steam generator is a device that converts the chemical energy, electrical energy, nuclear energy and other energy of fuel into thermal energy, and then heats water to boiling and produces steam through heat exchange. The existing technology model is: QXG1.0-0.8-SCIII.

[0030] After installation, connect the cold water pipe to the steam suction assembly 5. Then start the components, steam generator and steam suction assembly 5 to move. When the drive component works, it will drive the two steam cylinders 1 to rotate relative to each other. Then the relevant equipment will transport the corrugated paper between the two steam cylinders 1. When the steam cylinder 1 rotates, it will drive the friction ring 3 connected to the surface to rotate together, so that the friction ring 3 can transport the corrugated paper.

[0031] When the steam generator is working, it will deliver the generated steam to the steam inlet 7, and then the steam inlet 7 will deliver the steam to the two steam heating components 6. The steam heating components 6 will deliver the steam to the surface of the corrugated paper through the circular hole 2 on the steam cylinder 1, and heat the corrugated paper with steam to maintain a certain temperature and humidity. By directly spraying the steam onto the corrugated paper, the surface temperature of the corrugated paper can be kept consistent, avoiding local overheating or undercooling.

[0032] In the above-mentioned process, when the steam suction component 5 is working, it will collect the excess steam after the ejected steam comes into contact with the corrugated paper and then absorb the steam into the interior. At this time, the operator will open the cold water pipe connected to the steam suction component 5 so that the steam comes into contact with the cold water pipe inside the steam suction component 5, thereby reducing the temperature of the steam and causing the steam to condense into water. The steam suction component 5 will then collect the condensed steam.

[0033] When cold water comes into contact with steam, the cold water absorbs the heat from the steam, condensing the steam into water and simultaneously raising the temperature of the cold water, thus allowing the steam to be recovered and reused.

[0034] In Example 2, further, in order to achieve the purpose of the steam heating component 6 delivering steam to the corrugated paper, see [reference needed]. Figure 3 and Figure 4 The steam heating assembly 6 includes a steam pipe 61, which is installed on the steam inlet 7 and the outlet. The surface of the steam pipe 61 is provided with a plurality of steam outlet cylinders 63 corresponding to the circular holes 2 located at the bottom. The inner surface of the steam cylinder 1 is provided with a plurality of sealing rings 62, which are arranged in pairs to limit and seal the steam outlet cylinders 63.

[0035] Furthermore, each of the steam outlet cylinders 63 is provided with a steam outlet 64 that communicates with the circular hole 2.

[0036] In the above process, the steam generator delivers steam to the steam pipe 61 through the steam inlet 7. The steam then gradually flows through the steam pipe 61 to the steam outlet 63, which delivers the steam through the circular hole 2 to the corrugated paper to heat the corrugated paper.

[0037] In the above description, the steam pipe 61 is rotatably installed inside the steam cylinder 1. When the driving element drives the steam cylinder 1 to rotate, the steam pipe 61 remains stationary, thereby keeping the steam outlet cylinder 63 stationary. When the steam cylinder 1 rotates, it will drive the sealing ring 62 to rotate together. At this time, the lower outlet of the steam outlet cylinder 63 will be in a group of two steam outlet cylinders 63, causing the sealing ring 62 to slide on the steam outlet cylinder 63 and seal the outlet of the steam outlet cylinder 63. When the steam cylinder 1 rotates, the circular hole 2 opened on its surface will indirectly communicate with the steam outlet cylinder 63, so that the steam cylinder 1 will not affect the steam delivery when conveying corrugated paper.

[0038] Furthermore, in order to achieve the goal of steam recovery and reuse by the steam intake assembly 5, see [reference needed]. Figure 5 and Figure 6 The steam intake assembly 5 includes four fixing rings 53, which are respectively installed in front of two fixing plates 4. The two fixing rings 53 located on the same plane are provided with a conveying pipe 51. Several steam inlet pipes 52 are provided on opposite sides of the surfaces of the two conveying pipes 51. The outlets of the two conveying pipes 51 are provided with a converging pipe 54 for converging flow.

[0039] Furthermore, the outlet of the confluence pipe 54 is equipped with a condensation mechanism 55 for recovering and utilizing steam;

[0040] Furthermore, the condensation mechanism 55 includes a cylindrical cylinder 551, which is installed at the outlet of the confluence pipe 54 and communicates with the confluence pipe 54. A fan 554 for driving is provided on the left side of the cylindrical cylinder 551. Water pipes 552 are symmetrically arranged on the upper and lower sides of the cylindrical cylinder 551. A spiral pipe 553 is provided between the two water pipes 552. A liquid storage tank 556 is provided on the lower side of the cylindrical cylinder 551.

[0041] Furthermore, a through hole communicating with the liquid storage cylinder 556 is provided on the lower side of the inner surface of the cylindrical cylinder 551, and a liquid level line 555 is provided on the surface of the liquid storage cylinder 556.

[0042] In the above, the cold water pipe is connected to the upper water supply pipe 552, and the water supply pipe is connected to the lower water supply pipe 552. When the steam generator is started, the operator starts the blower 554 at the same time. The blower 554 collects the excess steam after contact with the corrugated paper through the delivery pipe 51 and the steam inlet pipe 52, and absorbs the steam into the confluence pipe 54. At this time, the confluence pipe 54 will then deliver the steam into the cylindrical cylinder 551.

[0043] In the above process, after the upper water supply pipe 552 is connected to the cold water pipe, the operator opens the cold water pipe, allowing cold water to flow from the upper water supply pipe 552 into the spiral tube 553 and then out of the lower water supply pipe 552. When steam flows into the cylindrical tube 551, it comes into contact with the surface of the spiral tube 553. At this time, the cold water flowing in the spiral tube 553 absorbs the heat of the steam, causing the cold water to heat up and the steam to condense into water. The condensed steam then flows into the liquid storage tank 556, where the liquid storage tank 556 collects the condensate, thus realizing the recovery and reuse of steam.

[0044] As described above, the liquid level line 555 on the liquid storage cylinder 556 allows the operator to observe the condensate content in the liquid storage cylinder 556 through the liquid level line 555. The liquid storage cylinder 556 is double-layered, with the upper layer fixedly connected to the lower part of the circular cylinder 551 and the lower layer threadedly connected to the upper layer. When the liquid storage cylinder 556 is full of condensate, the operator can rotate the lower layer to separate the upper and lower layers, pour out the condensate in the lower layer, and then screw the lower layer back into the upper layer.

[0045] It should be noted that the specific installation method, circuit connection method and control method of the fan 554 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
