Description

Technical Field

[0001] The utility model belongs to the field of paper processing equipment, and particularly relates to a paper processing and drying device with a water-vapor separation structure. Background Art

[0002] A paper processing and drying device is a device used for drying paper during the paper production process. The current paper processing and drying devices have some disadvantages without a water-vapor separation structure. First of all, due to the lack of a water-vapor separation function, the water vapor in the hot air will continuously accumulate, resulting in a decrease in drying efficiency. As the drying process progresses, the water vapor content in the air gradually increases, causing the drying ability of the hot air to decline, the evaporation rate of the water in the paper to slow down, thereby prolonging the drying time and reducing the production efficiency. The reason for this disadvantage is that the hot air continuously absorbs the water vapor evaporated from the paper during the circulation process, and there is no effective separation means to discharge the water vapor. The conventional countermeasure is to increase the ventilation volume to reduce the water vapor content in the air by increasing the flow rate of the hot air. However, this method has drawbacks. On the one hand, increasing the ventilation volume will lead to an increase in energy consumption because a larger power fan is required to drive the air flow; on the other hand, an excessive ventilation volume may cause the wind speed on the paper surface to be too high, resulting in problems such as paper deformation and wrinkling, affecting the paper quality. In addition, simply increasing the ventilation volume cannot fundamentally solve the problem of water vapor accumulation, but only alleviates the decline in drying efficiency to a certain extent. Therefore, a new structure is needed to solve the above technical problems. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a paper processing and drying device with a water-vapor separation structure to solve the problems put forward in the above background art.

[0009] As a preferred embodiment, one end of the pipe 2 away from the drying box is connected to the air outlet end of the condenser. Check valves are installed inside both the pipe 2 and the pipe 1. Sealing rings are arranged at the connection positions between the pipe 1 and the condenser and the air suction cylinder, and between the pipe 2 and the condenser and the drying box (the sealing rings used for the pipe 1 and the pipe 2 have the same structure). When in use, through the connection of the pipe 1 and the pipe 2, the hot air containing water vapor can smoothly flow from the inside of the drying box of the drying component to the water vapor separation component through the air suction component, and then after the water vapor separation by the condenser, the dry air can return to the drying component through the pipe and continue to participate in the drying process of the paper.

[0019] Please refer to Figures 1 to 2 , the present invention provides a technical solution: a paper processing and drying device with a water vapor separation structure, including: a conveyor member 100, a drying assembly 270, and a water vapor separation assembly 340. A drying assembly 270 is installed above the conveyor member 100. The drying assembly 270 is connected to the water vapor separation assembly 340 through a first pipe 310 and a second pipe 320. The drying assembly 270 includes: a drying box 200, a box door 210, a drying member, a control board 220, and a filter screen 260. An accommodation cavity is provided inside the drying box 200. Drying members are symmetrically installed on the upper side surface inside the drying box 200. A filter screen 260 is installed on the upper side surface inside the drying box 200. The front side surface of the drying box 200 is symmetrically and dampingly hinged with box doors 210. A control board 220 is installed on the front side surface of the box door 210. The water vapor separation assembly 340 includes: a suction member, a first pipe 310, a second pipe 320, and a condenser 300. The suction member is installed on the upper side surface of the drying box 200. A first pipe 310 is installed on the upper side surface of the suction member. A second pipe 320 is installed on the right side surface of the drying box 200. One end of the second pipe 320 away from the drying box 200 is connected to the condenser 300.

[0020] Please refer to Figures 1 to 2 , as the first embodiment of the present invention: a groove with a U-shaped structure is formed by the downward depression of the lower side surface of the drying box 200. The lower side surface of the drying box 200 is designed to be open. A box door 210 is symmetrically and dampingly hinged to the left and right edges of the front side surface of the drying box 200 respectively. A sealing ring is provided at the contact position between the box door 210 and the drying box 200;

[0021] A control board 220 is installed on the front side surface of the right box door 210. The drying member includes: an electric push rod 230, a mounting plate 240, and an electric heating plate 250. Two electric push rods 230 are symmetrically installed on the upper side surface inside the drying box 200. One end of the electric push rod 230 away from the drying box 200 is installed with a mounting plate 240. An electric heating plate 250 is installed on the side surface of the mounting plate 240 away from the electric push rod 230;

[0022] When in use, according to the attached drawings of the specification Figure 1As shown in the figure, place the paper to be dried on the upper surface of the conveyor 100 (place the paper on the left or right side of the upper surface of the conveyor 100, and try not to place it at the center position of the upper surface of the conveyor 100, as it will affect the drying effect of the paper), and then convey the paper to the opening at the lower surface of the drying box 200 through the conveyor 100 (the thickness of the paper shall not be higher than the height between the conveyor 100 and the lower groove of the drying box 200). When the paper is conveyed below the drying box 200, stop the conveyance at this time. Then the user opens the door 210 on the front surface of the drying box 200, and then synchronously starts two electric push rods 230 through the control panel 220 on the surface of the door 210, so that the electric push rods 230 drive the mounting plate 240 and the electric heating plate 250 on the lower surface of the mounting plate 240 to move downward, so that the electric heating plate 250 is located above the paper. After adjusting the height of the electric heating plate 250, close the door 210. At this time, the user can start the electric heating plate 250 to dry the paper (as for the heating temperature and heating time, they can both be controlled through the control panel 220, and the specific data can be selected according to the actual situation, which will not be elaborated here). When heating and drying the paper, the hot air containing water vapor will float upward along the inside of the drying box 200 and gather above the inside of the drying box 200. Then, through the water vapor separation component 340, the hot air containing water vapor is separated. After the operation is completed, the user can convey the dried paper out through the conveyor 100 through the above steps (after the paper is output, for the curling of the paper caused by heating, etc., the user can install the subsequent paper processing structure according to actual needs. The subsequent paper processing structure is prior art and will not be elaborated here). Since during use, the electric push rod 230 can flexibly adjust the positions of the mounting plate 240 and the electric heating plate 250, and can accurately adjust the heating distance according to different drying stages of the paper, ensuring that all parts of the paper are evenly heated, maximizing the heat utilization efficiency, thereby accelerating the evaporation speed of the moisture in the paper and significantly improving the drying efficiency.

[0023] Please refer to Figures 1 to 2 , as the second embodiment of the present utility model: The drying member is electrically connected to the power supply and the control panel 220 through a wire. A filter screen 260 is installed at the center position of the upper surface inside the drying box 200. The air suction member includes: an air suction cylinder 330 and an axial flow air suction fan 331. The air suction cylinder 330 is installed at the center position of the upper surface of the drying box 200, and the axial flow air suction fan 331 is installed inside the air suction cylinder 330. The central axis of the air suction end of the axial flow air suction fan 331 is collinear with the central axis of the filter screen 260;

[0024] The upper side surface of the air suction cylinder 330 is equipped with a first pipeline 310. The first pipeline 310 has the same structure as the second pipeline 320. One end of the first pipeline 310 away from the air suction cylinder 330 is connected to the inlet end of the condenser 300;

[0025] One end of the second pipeline 320 away from the drying oven 200 is connected to the air outlet end of the condenser 300. Check valves are installed inside both the second pipeline 320 and the first pipeline 310. Sealing rings are provided at the connections between the first pipeline 310 and the condenser 300 as well as the air suction cylinder 330, and sealing rings are provided at the connections between the second pipeline 320 and the condenser 300 as well as the drying oven 200;

[0026] During use, when the drying component 270 dries the paper, the hot air containing water vapor will gather above the inside of the drying oven 200. At this time, the user can start the axial flow air blower 331 inside the air suction cylinder 330, so that a negative pressure suction is generated by the axial flow air blower 331 below the filter screen 260, thereby transferring the hot air containing water vapor to the first pipeline 310, filling the first pipeline 310 with hot air containing water vapor. Then the first pipeline 310 transfers the hot air containing water vapor to the condenser 300. At this time, the condenser 300 works to condense and liquefy the hot air containing water vapor, thereby separating the water vapor in the air from the air (the condenser 300 is a prior art, and its specific equipment can be selected from existing market models, as long as it meets the use of the equipment, and its working principle and structure will not be elaborated here). Then the user can discharge the liquefied water vapor through the drain port of the condenser 300. Then the air outlet end of the condenser 300 discharges the separated air into the drying oven 200 through the second pipeline 320, thus forming a cycle. Since during use, through the connection of the first pipeline 310 and the second pipeline 320, the hot air containing water vapor can smoothly be discharged from the inside of the drying oven 200 of the drying component 270 to the water vapor separation component 340 through the air suction component, and then after the water vapor separation by the condenser 300, the dry air can return to the drying component 270 through the pipeline and continue to participate in the paper drying process. In this way, the recycling of air is realized, ensuring air circulation and greatly improving the drying efficiency and effect.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
