Description

Technical Field

[0001] This utility model relates to the field of papermaking wire mesh cleaning technology, specifically a papermaking wire mesh cleaning and drying device. Background Technology

[0002] In papermaking, papermaking wire mesh is a core component in the paper forming stage. Its mesh structure directly determines the pulp filtration effect and fiber interlacing pattern, which in turn affects key qualities such as paper thickness uniformity, surface smoothness, and physical strength. During long-term production, residual pulp fibers, fillers (such as calcium carbonate), and sizing agents easily adhere to the surface of papermaking wire mesh. If it is not cleaned regularly, it will clog the mesh, reduce filtration efficiency, and may also accelerate the wear and aging of the wire mesh, shorten its service life, and increase the production cost of enterprises. In order to maintain the performance of papermaking wire mesh, the industry needs to clean it with cleaning equipment.

[0003] However, existing cleaning solutions, such as soaking or rinsing, have limited effectiveness in removing stubborn, tightly attached impurities. They also fail to achieve simultaneous and coordinated soaking and brushing, resulting in poor cleaning efficiency. Furthermore, the cleaned wire mesh often needs to be transferred to a drying device for processing. During this process, the wire mesh becomes excessively wet, which not only increases the difficulty and time cost of operation but also makes it prone to secondary pollution due to excessive moisture combining with air impurities.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0024] Reference Figure 1-6 This is the first embodiment of the present invention, which provides a papermaking wire mesh washing and drying device, including a tank body 1, an inlet valve 2 and an outlet valve 3. The inlet valve 2 is fixedly connected to the upper left side of the tank body 1 and communicates with the tank body 1. The outlet valve 3 is fixedly connected to the lower left side of the tank body 1 and communicates with the tank body 1. A partition 4 is provided inside the tank body 1 and is fixedly connected to the inner wall of the tank body 1. A wire mesh inlet 7 is opened at the upper left side of the tank body 1, and a wire mesh outlet 8 is opened at the upper right side of the tank body 1. A wire mesh passage 9 is opened at the upper end of the partition 4.

[0025] The tank 1 on the left side of the partition 4 is a disinfection chamber 10, which is equipped with a cleaning mechanism 5. The tank 1 on the right side of the partition 4 is a drying chamber 11, which is equipped with a drying mechanism 6.

[0026] Specifically, it enables integrated and continuous operation of soaking, brushing, and drying of papermaking wire mesh in cleaning solution, effectively improving cleaning efficiency and cleanliness, and avoiding subsequent secondary pollution.

[0027] Furthermore, the water inlet valve 2 injects liquid into the cleaning chamber 10. After the wire mesh enters through the mesh inlet 7, it is soaked and brushed by the cleaning mechanism 5, and then enters the drying chamber 11 through the mesh inlet 9. After being dried by the drying mechanism 6, it passes out through the mesh outlet 8, and the wastewater is discharged through the water outlet valve 3. All components work together to achieve the cleaning and drying of the wire mesh. Example

[0028] In the second embodiment of this utility model, the cleaning mechanism 5 includes guide rollers 51 and a light brush assembly 52. ​​There are four guide rollers 51, which are respectively arranged on the left and right sides and the left and right sides at the bottom of the inside of the disinfection chamber 10. Both the front and rear ends are rotatably connected to the tank body 1. The two guide rollers 51 at the top correspond to the inlet 7 and the outlet 9. The light brush assembly 52 is arranged at the bottom of the inside of the disinfection chamber 10 and is located between the two guide rollers 51 at the bottom.

[0029] The light brush assembly 52 includes two rotating rods 521, brush cylinders 522, gears 523, and a motor 524. There are two rotating rods 521, both of which are located inside the lower side of the disinfection chamber 10 and are arranged vertically. The front and rear ends of the two rotating rods 521 extend out of the groove 1 and are rotatably connected to the groove 1. There are two brush cylinders 522, which are respectively sleeved on the surface of the two rotating rods 521 and are fixedly connected to the rotating rods 521. There are two gears 523, which are respectively fixedly connected to the rear ends of the two rotating rods 521 and are meshed with each other. The motor 524 is fixedly connected to the front end of the upper rotating rod 521 and is fixedly connected to the front surface of the groove 1.

[0030] Specifically, by setting up the cleaning mechanism 5, the guiding and conveying of the papermaking wire mesh can be synchronized with the soaking and brushing of the cleaning solution, thereby improving the efficiency of impurity removal.

[0031] Furthermore, the four guide rollers 51 are rotatably connected to the tank 1 to provide multi-directional guidance and support for the wire mesh. The upper left guide roller 51 guides the wire mesh smoothly into the cleaning chamber 10 from the inlet 7. The lower left and right guide rollers 51 ensure that the wire mesh is fully immersed in the cleaning solution and kept flat. The upper right guide roller 51 connects the wire mesh and conveys it to the outlet 9. In the brush assembly 52, the motor 524 drives the upper rotating rod 521 to rotate. The gears 523 meshing at the rear ends of the two rotating rods 521 drive the lower rotating rod 521 to rotate in the opposite direction, causing the two brush cylinders 522 sleeved on the rotating rods 521 to rotate in opposite directions. When the wire mesh passes between the two brush cylinders 522, the rotating brush cylinders 522 can thoroughly brush the upper and lower surfaces of the soaked wire mesh, achieving efficient removal of impurities. Example

[0032] In the third embodiment of this utility model, the drying mechanism 6 includes an air supply component 61 and a drying unit 62. The air supply component 61 is disposed at the upper end of the drying chamber 11, and the drying unit 62 is disposed at the lower end of the front right side of the tank 1.

[0033] The air supply assembly 61 includes a rectangular air plate 611, a fixing seat 612, a long strip air outlet 613, and a Y-shaped connecting pipe 614. There are two rectangular air plates 611, which are set at the upper part of the drying chamber 11 and arranged opposite each other. There are eight fixing seats 612, which are fixedly connected to the four corners of the upper surface of the upper rectangular air plate 611 and the four corners of the lower surface of the lower rectangular air plate 611. All eight fixing seats 612 are fixedly connected to the trough 1. There are several long strip air outlets 613, which are evenly opened on the side surface of the two rectangular air plates 611 that are close to each other. The Y-shaped connecting pipe 614 is set on the front side of the two rectangular air plates 611, and its rear end is fixedly connected to and communicates with the two rectangular air plates 611, and its front end extends out of the trough 1.

[0034] The drying unit 62 includes a drying hot air blower 621 and a conveying pipe 622. The drying hot air blower 621 is located at the lower end of the front right side of the tank 1. The conveying pipe 622 is fixedly connected to the output end of the drying hot air blower 621, and its upper end is fixedly connected to the front end of the Y-type connecting pipe 614.

[0035] Specifically, by setting up the drying mechanism 6, it can provide uniform hot air in both directions after cleaning the wire mesh, quickly evaporate residual moisture, avoid secondary pollution and wire mesh corrosion, and adapt to the needs of continuous operation.

[0036] Furthermore, after the drying hot air blower 621 in the drying unit 62 is started, the generated hot air is transported to the Y-type connecting pipe 614 through the conveying pipe 622. The Y-type connecting pipe 614 evenly distributes the hot air to the two rectangular air plates 611 in the drying chamber 11. The hot air is blown synchronously onto the upper and lower surfaces of the wire mesh passing between the two air plates through the elongated air outlets 613 evenly opened on opposite sides of the two rectangular air plates 611. The residual moisture is quickly removed through heat exchange, thus completing the wire mesh drying process.

[0037] In use, the papermaking wire mesh to be cleaned is inserted into the cleaning chamber 10 through the inlet 7 at the upper left side of the tank 1. First, it passes around the guide roller 51 at the upper left side of the cleaning chamber 10. The guide roller 51 guides the wire mesh by rotating itself, ensuring that the wire mesh enters the cleaning area smoothly. Then, the wire mesh extends downward, passes around the guide roller 51 at the lower left side of the cleaning chamber 10 in sequence, passes between the two brush cylinders 522, and then passes around the two guide rollers 51 at the lower right side of the cleaning chamber 10 in sequence. It then passes through the wire mesh opening 9 on the partition plate 4 into the drying chamber 11, and then passes between the two rectangular air plates 611 before exiting through the outlet 8 and connecting to the external winding equipment.

[0038] Then, inject sufficient cleaning fluid into the cleaning chamber 10 through the water inlet valve 2 at the upper left side of the tank 1 until the liquid level completely covers the lower guide roller 51 and the light brush assembly 52, ensuring that the wire mesh can be fully immersed in the cleaning fluid during the cleaning stage, and then close the water inlet valve 2.

[0039] When the device is running, the external winding equipment starts and provides stable traction, driving the wire mesh to be continuously conveyed along the preset path. Inside the cleaning chamber 10, when the wire mesh passes the upper left guide roller 51, the guide roller 51 rotates synchronously with the wire mesh by means of friction, guiding it. Then the wire mesh extends downward and passes the lower left guide roller 51, at which point it is completely immersed in the cleaning solution. The chemical components in the cleaning solution quickly penetrate the wire mesh pores, softening and decomposing the attached pulp fibers, calcium carbonate fillers, sizing agents, and other impurities, preparing for the brushing stage. Subsequently, the wire mesh enters the light... In the brush assembly 52 area, passing between two vertically arranged brush cylinders 522, the control motor 524 starts, driving the upper rotating rod 521 to rotate. Because the gears 523 at the rear ends of the two rotating rods 521 mesh with each other, the upper rotating rod 521 synchronously drives the lower rotating rod 521 to rotate in the opposite direction, causing the two brush cylinders 522 to rotate in opposite directions. The rotating brush cylinders 522 are in close contact with the upper and lower surfaces of the mesh, thoroughly removing stubborn impurities softened by the cleaning solution. At the same time, the rotation of the brush cylinders 522 can also agitate the cleaning solution, forming a localized water flow to flush the mesh pores. To further remove residual impurities and achieve a synergistic cleaning effect of soaking and brushing, after brushing, the wire mesh continues to be conveyed to the right, passing in sequence around the two guide rollers 51 on the lower right side of the washing chamber 10. Then, the wire mesh passes upward through the mesh opening 9 on the partition 4 and smoothly enters the right-side drying chamber 11. After entering the drying chamber 11, the wire mesh precisely passes between two vertically arranged rectangular air plates 611. The two rectangular air plates 611 are firmly installed on the upper part of the drying chamber 11 by eight fixing seats 612, and several long strip-shaped air outlets are evenly opened on their opposite sides. The hot air is delivered via pipe 622 to Y-shaped connecting pipe 614, and then distributed to two rectangular air plates 611 in the drying chamber 11. The hot air delivered by Y-shaped connecting pipe 614 is evenly blown onto the upper and lower surfaces of the wire mesh, and the hot air comes into full contact with the cleaning liquid remaining on the surface of the wire mesh. Through heat exchange, the moisture is quickly evaporated. Finally, the dried wire mesh is passed out from the outlet 8 at the upper right side of the tank 1 and continuously wound up by the external winding equipment. The whole process realizes the continuous operation of "cleaning, brushing and drying", which greatly improves the cleaning efficiency and facilitates subsequent processing. After all the wire mesh is processed, the motor 524 and the hot air drying fan 621 are turned off, and the water outlet 3 at the lower left side of the tank 1 is opened to discharge the wastewater containing impurities in the cleaning chamber 10, which facilitates the subsequent cleaning and maintenance of the equipment and prepares it for the next use.

[0040] In summary, by using the tank 1, water inlet valve 2, water outlet valve 3, baffle 4, cleaning mechanism 5, guide roller 51, light brush assembly 52, rotating rod 521, brush cylinder 522, gear 523, motor 524, drying mechanism 6, air supply assembly 61, rectangular air plate 611, fixed base 612, long strip air outlet 613, Y-type connecting pipe 614, drying unit 62, drying hot air blower 621, conveying pipe 622, screen inlet 7, screen outlet 8, screen passage 9, disinfection chamber 10, and drying chamber 11 in coordination, the effect of simultaneous and coordinated soaking and brushing of cleaning solution, and integrated continuous operation of cleaning and drying is achieved.
