Description

Technical Field

[0001] The invention relates to the technical field of glass fiber cloth drying, and in particular to a drying device and a drying method for glass fiber cloth production. Background Art

[0002] As an important industrial material, fiberglass cloth needs to be strictly dried during the production process to remove excess moisture and ensure its physical properties and processing adaptability. Traditional fiberglass cloth drying equipment usually uses a single space for high-temperature drying. Although it can achieve basic drying effects, it still has problems such as high energy consumption, uneven drying, and deformation or damage of fiberglass cloth. In addition, the thermal energy utilization rate of this type of equipment is low, and the waste heat of high-temperature gas is not fully utilized, resulting in energy waste and increased production costs.

[0003] Although some existing equipment has tried to introduce segmented drying technology, it still cannot avoid excessive stretching or deformation of the fiberglass cloth during the drying process due to the lack of effective fiberglass cloth protection and transmission structure. At the same time, the air circulation design in the equipment is often not perfect, resulting in the inability to efficiently recycle heat energy, further reducing the overall production efficiency.

[0032] S9, the glass fiber cloth is pressed by the ironing roller in the ironing unit, and the heating net inside the ironing roller provides heat for the ironing roller to flatten the surface of the glass fiber cloth;

[0033] S10, the air in the pre-drying space is extracted by the exhaust fan, passes through a filter to remove moisture and impurities, and then enters the heating channel of the ironing roller for heating treatment;

[0034] S11. The heated air returns to the intensive drying space through the air outlet channel, forming an efficient recycling and reducing heat energy waste.

[0035] Compared with the prior art, the present invention has the following advantages:

[0036] 1. Through the segmented drying structure, the drying box is divided into pre-drying space and strong drying space, and the high-temperature gas in the strong drying space is introduced into the pre-drying space by using an air suction pump. The residual heat of the high-temperature gas in the strong drying space is used for preliminary drying of the glass fiber cloth, which fully realizes the recycling of waste heat without the need for additional energy input, thereby significantly reducing energy consumption;

[0037] 2. A shaking box is set in the pre-drying space.

In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may also be implemented by those skilled in the art without these specific details.

[0050] like Figure 1-Figure 3As shown, a drying device for glass fiber cloth production includes a drying unit 1, and the drying unit 1 includes a drying box 101, an isolation plate 102, a placement port 103, a movable component 104, a pre-drying space 105, a strong drying space 106, a first guide section 107, a second guide section 108, a feed port 109, a discharge port 1010, an air suction pump 1011, several connecting channels 1012, two shaking boxes 1013, a branch channel 1014, two air outlets 1015, two pistons 1016, two elastic components 1017, two connecting rods 1018 and two shaking plates 1019.

[0051] An isolation plate 102 is arranged in the drying box 101 . The isolation plate 102 is connected to the drying box 101 . A placement opening 103 is provided on the isolation plate 102 . A movable component 104 is arranged at the placement opening 103 . The movable component 104 is connected to the isolation plate 102 .

[0052] The isolation plate 102 divides the interior of the drying box 101 into a pre-drying space 105 and a strong drying space 106. The pre-drying space 105 and the strong drying space 106 are connected through the movable part 104. A first guide section 107 is set in the pre-drying space 105, and a second guide section 108 is set in the strong drying space 106. The first guide section 107 and the second guide section 108 are both connected to the drying box 101.

[0053] A feed port 109 is provided on one side of the drying box 101 where the pre-drying space 105 is provided, and a discharge port 1010 is provided on one side of the drying box 101 where the intensive drying space 106 is provided. The positions of the feed port 109 and the discharge port 1010 correspond to each other.

[0054] An air suction pump 1011 is arranged on the top of the drying box 101 , and the air suction end of the air suction pump 1011 is connected to the strong drying space 106 through the connecting channel 1012 , and the air outlet end of the air suction pump 1011 is connected to the pre-drying space 105 through the connecting channel 1012 .

[0055] Two shake boxes 1013 are arranged in the pre-drying space 105, and both shake boxes 1013 are connected to the drying box 101. One end of the connecting channel 1012 in the pre-drying space 105 is connected to the tops of the two shake boxes 1013 through a branch channel 1014. An air outlet 1015 is also arranged on the top of the shake box 1013, and the air outlet 1015 is connected to the shake box 1013.

[0056] A piston 1016 is provided inside the shake box 1013, and the piston 1016 is slidably matched with the shake box 1013. The piston 1016 is provided with an elastic component 1017 and a connecting rod 1018. One end of the elastic component 1017 is connected to the outer edge of the bottom of the piston 1016, and the other end of the elastic component 1017 is connected to the inner wall of the shake box 1013. One end of the connecting rod 1018 is connected to the center of the bottom of the piston 1016, and the other end of the connecting rod 1018 extends through the shake box 1013 to the outside of the shake box 1013. The connecting rod 1018 is slidably matched with the shake box 1013. A shaking plate 1019 is provided between the two connecting rods 1018, and the shaking plate 1019 is connected to the connecting rod 1018.

[0057] The above-mentioned drying device for glass fiber cloth production is used with the drying box 101 of the device as the main body, and the drying box 101 is provided with a heat-insulating interlayer. The heat-insulating interlayer can effectively reduce the heat loss in the drying box 101 to the outside, and keep the temperature inside the box stable. The interior of the drying box 101 is divided into a pre-drying space 105 and a strong drying space 106 by an isolation plate 102, thereby forming a segmented drying structure.

[0058] Specifically, the pre-drying space 105 uses relatively low-temperature airflow to preliminarily dry the glass fiber cloth 4 to prevent deformation or damage caused by the direct effect of high temperature on the wet glass fiber cloth 4, while the strong drying space 106 uses high-temperature airflow to perform deep drying to ensure that the moisture in the glass fiber cloth 4 is completely evaporated. The placement port 103 provided on the isolation plate 102 is connected to the two spaces through the movable component 104.

[0059] After the glass fiber cloth 4 enters the drying box 101 through the feed port 109, it is first supported and flattened by the first guide section 107 of the pre-drying space 105, ensuring that the glass fiber cloth 4 enters the drying process smoothly.

[0060] In the pre-drying space 105, the suction pump 1011 extracts high-temperature gas from the strong drying space 106 and introduces it into the pre-drying space 105 through the connecting channel 1012, and uses the waste heat of the high-temperature gas to preliminarily dry the fiberglass cloth 4, thereby improving the thermal energy utilization efficiency and achieving energy-saving effects.

[0061] A shaking box 1013 is provided in the pre-drying space 105, and a piston 1016 is provided in the shaking box 1013. The movement of the piston 1016 is driven by the intermittent operation of the suction pump 1011. When the suction pump 1011 is turned on, the airflow pushes the piston 1016 downward. When the suction pump 1011 is turned off, the elastic component 1017 resets the piston 1016 and squeezes the gas in the shaking box 1013, and introduces the airflow into the pre-drying space 105 through the air outlet 1015, wherein the air outlet 1015 can be automatically closed or opened with the start and stop of the suction pump 1011.

[0062] Specifically, the shake box 1013 is cylindrical, which can help the piston 1016 to slide smoothly in the shake box 1013 and avoid uneven friction or deviation caused by irregular shape.

[0063] like Figure 4 As shown, the elastic component 1017 includes two annular plates 1017-1 and a plurality of springs 1017-2 located between the two annular plates 1017-1, the plurality of springs 1017-2 are distributed at equal distances between the two annular plates 1017-1, and both ends of the springs 1017-2 are connected to the adjacent annular plates 1017-1. The two annular plates 1017-1 connect the piston 1016 to the shake box 1013, and the springs 1017-2 between the annular plates 1017-1 can use the rebound force to quickly push the piston 1016 to reset after the force on the upper part of the piston 1016 is removed.

[0064] The piston 1016 is connected to the shaking plate 1019 through the connecting rod 1018, and the connecting plate supports a portion of the bottom of the glass fiber cloth 4. The shaking plate 1019 shakes the glass fiber cloth 4 while shaking up and down, accelerating the dispersion and evaporation of moisture between the fibers of the glass fiber cloth 4, thereby improving the drying efficiency. In order to avoid the stretching of the glass fiber cloth 4 caused by shaking, the movable part 104 will absorb the shaking impact to protect the structure of the glass fiber cloth 4.

[0065] like Figure 5 and Figure 6 As shown, specifically, the movable component 104 includes two slide rails 104-1, a rotating drum 104-2 and two elastic members 104-3. The two slide rails 104-1 are arranged correspondingly, and the slide rails 104-1 are connected to the isolation plate 102. The rotating drum 104-2 is arranged between the two slide rails 104-1, and the two ends of the rotating drum 104-2 are respectively slidably connected to the two slide rails 104-1. An elastic member 104-3 is arranged inside the slide rail 104-1, and the two ends of the elastic member 104-3 are respectively connected to the slide rail 104-1 and the rotating drum 104-2. The two slide rails 104-1 are arranged correspondingly and connected to the isolation plate 102, forming a guide track for the rotating drum 104-2. The rotating drum 104-2 is installed between the two slide rails 104-1 and is slidably connected to the slide rails 104-1, so that it can move smoothly on the slide rails 104-1, ensuring that when the glass fiber cloth 4 is shaken and pulled in the pre-drying space 105, a pulling space is provided for the glass fiber cloth 4, while maintaining its flat state during transportation. Among them, the elastic member 104-3 on the inner side of the slide rail 104-1 can ensure that the rotating drum 104-2 is quickly reset after moving to a different position.

[0066] After the pre-drying is completed, the glass fiber cloth 4 enters the strong drying space 106 through the movable component 104 .

[0067] In the strong drying space 106, the glass fiber cloth 4 continues to be transported along the second guide section 108, thereby ensuring the stability of the glass fiber cloth 4 in the high-temperature airflow. At this time, the high-temperature gas deeply dries the glass fiber cloth 4 and completely evaporates the moisture. After drying, the glass fiber cloth 4 leaves the drying box 101 through the discharge port 1010.

[0068] Among them, the first guide section 107 and the second guide section 108 have the same height, and the positions of the first guide section 107 and the second guide section 108 respectively match the positions of the feed port 109 and the discharge port 1010, and the heights of the first guide section 107 and the second guide section 108 are lower than the height of the movable part 104, and the first guide section 107 and the second guide section 108 are both composed of a plurality of guide rollers.

[0069] The first guide section 107 and the second guide section 108 have the same height, and their positions match the feed port 109 and the discharge port 1010, respectively, to ensure that the glass fiber cloth 4 can be accurately docked when entering and leaving the drying box 101. The heights of the first guide section 107 and the second guide section 108 are lower than the height of the movable part 104, so that the first guide section 107 forms a transition before the second guide section 108. The first guide section 107 and the second guide section 108 are both composed of a plurality of guide rollers, so that the glass fiber cloth 4 can obtain uniform support and guidance during the transmission process.

[0070] like Figure 7 As shown, the drying device for glass fiber cloth production further includes an ironing unit 2 , which includes an ironing roller 201 , a heating channel 202 , a heating net 203 , an exhaust fan 204 , two air inlet channels 205 and an air outlet channel 206 .

[0071] A heating channel 202 is provided inside the ironing roller 201 . A heating net 203 is arranged inside the heating channel 202 . The heating net 203 is connected to the inner wall of the ironing roller 201 .

[0072] An exhaust fan 204 is arranged between the ironing roller 201 and the drying box 101 , the air inlet end of the exhaust fan 204 is connected to the pre-drying space 105 through the air inlet channel 205 , and the air outlet end of the exhaust fan 204 is connected to one end of the ironing roller 201 through the air inlet channel 205 .

[0073] The other end of the ironing roller 201 is connected to the strong drying space 106 through the air outlet channel 206 .

[0074] A heating channel 202 is provided inside the ironing roller 201, and a heating net 203 is installed inside the heating channel 202 and connected to the inner wall of the ironing roller 201. The surface of the ironing roller 201 is evenly heated by the heating net 203 to reach a stable high temperature state. When the glass fiber cloth 4 passes through the ironing roller 201, the high temperature on the surface of the ironing roller 201 directly acts on the surface of the glass fiber cloth 4. Through the combination of heat and pressure, the surface of the glass fiber cloth 4 is fully ironed, thereby effectively reducing the wrinkle problem caused by the evaporation of water during the drying process, and making the glass fiber cloth 4 more flat and beautiful.

[0075] The air inlet end of the exhaust fan 204 is connected to the pre-drying space 105 through the air inlet channel 205, and the air outlet end of the exhaust fan 204 guides the airflow from one end of the ironing roller 201 into the interior of the ironing roller 201 through the air inlet channel 205, ensuring the continuous flow of the airflow in the heating channel 202 and recirculating the residual hot air in the pre-drying space 105. The other end of the ironing roller 201 is connected to the strong drying space 106 through the air outlet channel 206, and the hot air generated during the ironing process is transported to the strong drying space 106 to participate in the high-temperature drying link again. This improves the overall thermal energy utilization rate of the device and further reduces energy consumption.

[0076] It should be noted that a filter 3 is provided in the air inlet passage 205 between the drying box 101 and the exhaust fan 204. The filter 3 can filter the moisture and impurities in the circulating air to prevent the accumulation of moisture and impurities in the circulating gas.

[0077] A drying method for producing glass fiber cloth 4 comprises the following steps:

[0078] S1. The glass fiber cloth 4 to be processed is fed into the drying box 101 through the feed port 109. The glass fiber cloth 4 first passes through the first guide section 107, is supported and flattened by the guide roller, and then enters the pre-drying space 105 to ensure that the glass fiber cloth 4 is transported smoothly;

[0079] S2. In the pre-drying space 105, the suction pump 1011 discontinuously draws the air in the strong drying space 106 into the pre-drying space 105 to preliminarily dry the glass fiber cloth 4 with the air at a lower temperature than that in the strong drying space 106;

[0080] S3, each suction action of the suction pump 1011 triggers the movement of the piston 1016 in the shaking box 1013. When the suction pump 1011 is turned on, the high-temperature air pushes the piston 1016 downward; when the suction pump 1011 is turned off, the elastic component 1017 resets the piston 1016 and squeezes the air in the shaking box 1013 into the pre-drying space 105 through the air outlet 1015;

[0081] S4, the piston 1016 drives the shaking plate 1019 to shake up and down through the connecting rod 1018, causing the glass fiber cloth 4 to shake under the action of the shaking plate 1019, thereby accelerating the dispersion and evaporation of water between the fibers of the glass fiber cloth 4;

[0082] S5. When the glass fiber cloth 4 passes through the shaking plate 1019, in order to prevent excessive stretching caused by shaking, the glass fiber cloth 4 is transmitted through the rotating drum 104-2 of the movable component 104; the rotating drum 104-2 slides up and down along the slide rail 104-1 to absorb the shaking impact, and the elastic member 104-3 in the slide rail 104-1 can ensure that the rotating drum 104-2 is automatically reset, so that the glass fiber cloth 4 is transmitted smoothly and the structure of the glass fiber cloth 4 is protected;

[0083] S6, after the pre-drying is completed, the glass fiber cloth 4 smoothly enters the strong drying space 106 through the rotating drum 104-2 of the movable component 104;

[0084] S7, in the strong drying space 106, the glass fiber cloth 4 continues to be transported along the second guide section 108, and is deeply dried by the high-temperature air to completely evaporate the moisture of the glass fiber cloth 4;

[0085] S8, the dried glass fiber cloth 4 leaves the drying box 101 through the discharge port 1010 and is transferred to the ironing unit 2 for further processing;

[0086] S9, the glass fiber cloth 4 is pressed by the ironing roller 201 in the ironing unit 2, and the heating net 203 inside the ironing roller 201 provides heat for the ironing roller 201 to flatten the surface of the glass fiber cloth 4;

[0087] S10, the air in the pre-drying space 105 is extracted by the exhaust fan 204, passes through the filter 3 to remove moisture and impurities, and then enters the heating channel 202 of the ironing roller 201 for heating treatment;

[0088] S11. The heated air returns to the strong drying space 106 through the air outlet channel 206, forming an efficient recycling and reducing heat energy waste.

[0089] The implementation principle of a drying device and a drying method for glass fiber cloth production of the present invention is as follows:

[0090] By dividing the drying box 101 into a pre-drying space 105 and a strong drying space 106, a segmented drying structure is constructed to achieve efficient staged drying of the glass fiber cloth 4. After the glass fiber cloth 4 enters the drying box 101 through the feed port 109, it first enters the pre-drying space 105. At this stage, the high-temperature gas is extracted from the strong drying space 106 by the suction pump 1011 and transported to the pre-drying space 105, and the residual heat is used to perform preliminary drying on the glass fiber cloth 4. This process not only reduces the demand for additional heat sources during the drying process, but also avoids the direct effect of high temperature on the wet glass fiber cloth 4, effectively preventing the glass fiber cloth 4 from being deformed or damaged due to excessive drying.

[0091] The shaking box 1013 provided in the pre-drying space 105 causes the glass fiber cloth 4 to shake appropriately during the drying process through the linkage of the piston 1016 and the shaking plate 1019, thereby accelerating the evaporation of moisture between the fibers of the glass fiber cloth 4 and improving the drying efficiency. This shaking process can also maintain the flatness of the glass fiber cloth 4, laying a good foundation for subsequent high-temperature drying. Through the buffering function of the movable component 104, the shaking impact of the glass fiber cloth 4 during transmission is absorbed, further improving the stability and protection effect of the glass fiber cloth 4 during the drying process.

[0092] After pre-drying, the glass fiber cloth 4 enters the strong drying space 106 through the movable part 104. In the strong drying space 106, the glass fiber cloth 4 is transmitted along the second guide section 108, and the high-temperature gas deeply dries the glass fiber cloth 4 to completely evaporate the residual moisture. At the same time, the ironing roller 201 in the ironing unit 2 heats and flattens the surface of the glass fiber cloth 4, further enhancing the smoothness and uniformity of the surface of the glass fiber cloth 4. The ironing unit 2 realizes the recycling of airflow through the exhaust fan 204, extracting gas from the pre-drying space 105 and reintroducing it into the strong drying space 106 after being processed by the ironing roller 201, thereby further improving the thermal energy utilization efficiency.

[0093] The device is also provided with a filter 3, which can remove moisture and impurities in the airflow, thereby ensuring the cleanliness of the internal environment of the drying box 101 and the smoothness of the airflow circulation.

[0094] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
