Description

Technical Field

[0001] The invention relates to the technical field of aerogel felt dipping, in particular to an automatic uniform dipping device and method for aerogel felt. Background Art

[0002] Aerogel is a nano-scale porous solid material formed by using a sol-gel method to replace the liquid phase in the gel with gas in a certain drying method. It is one of the lowest density solids in the world. The high porosity of aerogel gives it excellent thermal insulation properties and can effectively prevent heat transfer.

[0003] ‌‌Aerogel glue solutions are currently mostly prepared by artificial dipping in the market, which often has the following defects: 1: On the one hand, artificial dipping takes up a lot of manpower and is inefficient. Working in this environment for a long time will cause certain harm to the human body. On the other hand, artificial dipping leads to unstable product performance. 2: When using manual dipping, manual discharging is often required during the feeding stage. Manual discharging is not only inefficient, but also the interval between the relative discharging positions is unstable. Therefore, it is urgent to develop a set of supporting automatic discharging equipment. Manual dipping leads to unstable product performance. The force of glue squeezing during manual dipping is uneven. In addition, there are factors such as different raw material thicknesses and uneven dipping time, which lead to large fluctuations in thickness and thermal conductivity of the products after dipping and squeezing. 3: The following situations often occur when using artificial dipping: the glue liquid has a short gel time under non-flowing working conditions; the glue liquid has a certain viscosity, especially as time goes by, the viscosity of the glue liquid increases, and the viscosity will also increase. In this case, the difficulty of dipping and squeezing glue is increased; 4: After production is completed, it is difficult to remove the glue on the equipment. Most of the time, the glue is removed manually after it solidifies, which wastes the glue and increases costs. 5. During the production process, the sheet-like raw felt and the rolled felt are separated into different dipping equipment, which takes up a lot of space and has a single function; 6: During the production process, some components in the glue solution have certain volatility and have a certain impact on the surrounding environment; for this purpose, an automatic and uniform glue dipping device and method for aerogel felt are provided.

[0013] A method for automatically and uniformly dipping aerogel felt is implemented using the automatic uniform dipping device of the present invention, and the specific steps are as follows: Step 1: Pass one end of the rolled felt through the flattening roller, the glue pouring pipe and the dipping and squeezing roller in sequence, and then manually adjust the adjustable bearing seat C and the adjustable bearing seat D or use the second servo motor to automatically adjust the adjustable bearing seat C and the adjustable bearing seat D, so that the dipping and squeezing roller descends to squeeze the rolled felt, and when the dipping and squeezing roller descends, the scraper in contact with the dipping and squeezing roller also descends; Step 2: The control cabinet controls the reduction motor and the circulation pump to work simultaneously.

At the same time, the circulation pump sucks the glue liquid in the recovery tank into the glass buffer tank, and by opening the feed switch valve, the glue liquid in the glass buffer tank is transported to the glue spraying pipeline, and the glue liquid flows out from the glue spraying hole at the bottom of the glue spraying pipeline to the surface of the roll felt; Step 3: The glue liquid on the felt roll is made more uniform by the glue-impregnating and squeezing roller, and the excess glue liquid adsorbed in the felt roll is squeezed out. The glue liquid flows into the glue-impregnating tank, and then flows into the recovery tank through the pipe at the bottom of the glue-impregnating tank. The glue liquid on the surface of the glue-impregnating and squeezing roller is scraped out by the scraper, so that the glue-impregnating and squeezing roller can more evenly impregnate the felt roll; Step 4: During the working process, the glue liquid is recycled through the circulating pipe system. When the glue liquid in the recovery tank is insufficient, it will be automatically replenished through the glue tank.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1.

After testing, under the condition of the same volume of sheet-like original felt, the production time is shortened by about 70%.

[0015] 2. Improved quality: The original felt passes through the glue spraying and dipping areas and fully absorbs the glue. According to a large amount of test data, the force of glue squeezing after dipping is uniform, the thickness of the dipped felt is uniform, and the time of dipping and squeezing is fully equal, ensuring that the thermal conductivity of the finished aerogel composite material is optimal and the surface is smoother.

[0016] 3. Saving of raw materials: The device adopts a glue liquid flow circulation process method, which allows the glue liquid to circulate, which can increase the gel time of the glue liquid during the dipping process. At the same time, the time when the viscosity of the glue liquid increases is postponed. Under the condition of the same volume of glue liquid, the output of the dipped felt is increased and the waste of glue liquid is reduced.

[0017] 4. Saving floor space: In the existing production process, sheet-like raw felt and rolled felt are produced in different devices and methods. The present invention combines the two into one, which simplifies the operation and greatly saves floor space.

The dual-channel correction sensor 119 is electrically connected to the first servo motor 113 through a controller. The dual-channel correction sensor 119 is used to detect whether the corrosion-resistant conveyor belt 109 is offset. If offset occurs, the first servo motor 113 is controlled by the controller to operate. When the corrosion-resistant conveyor belt 109 deviates toward the adjustable bearing seat E111, the first servo motor 113 is operated to fine-tune the position of the built-in bearing of the adjustable bearing seat E111, thereby adjusting the position of the driven roller 110 on its side, reducing the force on the corrosion-resistant conveyor belt 109 on its side, and the corrosion-resistant conveyor belt 109 deviates to the direction where it is subjected to greater force. Conversely, the force on the corrosion-resistant conveyor belt 109 is increased.

[0026] like Figure 1-2 As shown: adjustable bearing seat A104, adjustable bearing seat B116, adjustable bearing seat C105, adjustable bearing seat D107, adjustable bearing seat E111 and adjustable bearing seat F112 are all installed on the bracket 101 by bolts, and the first servo motor 113, the second servo motor 114 and the reduction motor 102 are all explosion-proof motors.

[0032] A method for automatically and uniformly dipping aerogel felt is implemented using the automatic uniform dipping device of the present invention, and the specific steps are as follows: Step 1: Pass one end of the rolled felt 201 through the flattening roller 202, the glue spraying pipe 108 and the dipping and squeezing roller 106 in sequence, and then manually adjust the adjustable bearing seat C105 and the adjustable bearing seat D107 or automatically adjust the adjustable bearing seat C105 and the adjustable bearing seat D107 using the second servo motor 114, so that the dipping and squeezing roller 106 descends to squeeze the rolled felt 201, and when the dipping and squeezing roller 106 descends, the scraper 501 in contact with the dipping and squeezing roller 106 also descends; Step 2: The control cabinet 115 controls the reduction motor 102 and the circulation pump 302 to work simultaneously. The reduction motor 102 drives the active roller 103 to rotate through the belt, so as to realize the rotation of the corrosion-resistant conveyor belt 109, thereby driving the roll felt 201 on the top of the corrosion-resistant conveyor belt 109 to move under the action of friction. At the same time, the circulation pump 302 sucks the glue liquid in the recovery tank 118 into the glass buffer tank 305, and by opening the feeding switch valve 306, the glue liquid in the glass buffer tank 305 is transported to the glue spraying pipeline 108, and the glue liquid flows out from the glue spraying hole at the bottom of the glue spraying pipeline 108 to the surface of the roll felt 201; Step 3: Under the action of the dipping and squeezing roller 106 squeezing the felt roll 201, the glue on the felt roll 201 is made more uniform, and the excess glue adsorbed in the felt roll 201 is squeezed out, and the glue flows into the dipping tank 117, and then flows into the recovery tank 118 through the pipeline at the bottom of the dipping tank 117. Under the action of the scraper 501, the glue on the surface of the dipping and squeezing roller 106 is scraped out, so that the dipping and squeezing roller 106 can dip the felt roll 201 more evenly; Step 4: During the working process, the glue liquid is recycled through the circulating pipe system. When the glue liquid in the recovery tank 118 is insufficient, it will be automatically replenished through the glue tank 307.

[0033] like Figure 7 As shown, a control system for automatic and uniform dipping of aerogel felt is provided, and the specific control method is as follows: In the first step, the control cabinet 115 gives a start signal to the suction device (auxiliary equipment, independent of the dipping device), and stops the suction device after production is completed; The second step is to set the required parameters related to the felt production in the control cabinet 115, confirm the parameters, and the whole device will automatically adjust the built-in bearing positions of the adjustable bearing seat C105 and the adjustable bearing seat D107 and the conveying speed of the corrosion-resistant conveyor belt 109 according to the set parameters; The third step is to detect and confirm that the glue solution is configured and the original felt is ready after the previous step is completed. After confirmation, the circulation pump 302 is started to automatically adjust the opening of the feed regulating valve 303 and the bypass electric regulating valve 304, and the glue solution feed flow rate is accurately adjusted through the PID algorithm; Step 4: After the above steps are completed, the control cabinet 115 sends a production start signal to the gripping device to place the original felt on the feeding end of the automatic uniform dipping device 100, and measure the number of dipped felt bodies. If the original felt is changed midway, the automatic uniform dipping device 100 is paused to cycle the above steps; The fifth step is to detect whether the production is completed according to the set workload, and clean the automatic uniform dipping device 100 after completion.

[0034] The above embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.

At the same time, the circulation pump (302) sucks the glue liquid in the recovery tank (118) into the glass buffer tank (305), and by opening the feeding switch valve (306), the glue liquid in the glass buffer tank (305) is transported to the glue spraying pipeline (108), and the glue liquid flows out through the glue spraying hole at the bottom of the glue spraying pipeline (108) to the surface of the roll felt (201); Step 3: Under the action of the impregnation and squeezing roller (106) squeezing the felt roll (201), the glue liquid on the felt roll (201) is made more uniform, and the excess glue liquid adsorbed in the felt roll (201) is squeezed out, and the glue liquid flows into the impregnation tank (117), and then flows into the recovery tank (118) through the pipeline at the bottom of the impregnation tank (117). Under the action of the scraper (501), the glue liquid on the surface of the impregnation and squeezing roller (106) is scraped out, so that the impregnation and squeezing roller (106) can impregnate the felt roll (201) more evenly; Step 4: During the working process, the glue liquid is recycled through the circulation pipeline system. When the glue liquid in the recovery tank (118) is insufficient, it will be automatically replenished through the glue tank (307).
