[0002] Aerogel refers to a nano-porous solid material formed by replacing the liquid phase in a gel with gas through a sol-gel method and using a certain drying method. In the existing process of impregnating a coil material, simply relying on the sol circulation cannot completely impregnate the material, and the remaining bubbles cannot be effectively discharged, resulting in the appearance and quality of the product not meeting the product requirements.

[0003] A patent with the publication number of CN213727455U provides a coil-shaped heat insulation material impregnation device, including a container, in which a shaft body is rotatably arranged, and the outer surface of the shaft body is wound with a heat insulation material in a reel shape.

[0004] According to the above technical solution, the applicant believes that there are the following defects: the material to be impregnated needs to be wound around the shaft body in a reel shape before impregnation. However, in the above solution, the shaft body is located inside the container, and the internal space of the container is limited, which is not convenient for winding or unwinding the material to be impregnated, thereby increasing the operation difficulty during winding or unwinding, and having certain limitations in actual use. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the embodiments described below are a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0023] As Figures 1-4 shown, the technical solution adopted by the present utility model is as follows: An online vacuum pumping device supporting an impregnating bath during the production process of aerogel, including an impregnating bath 2, and the impregnating bath 2 contains sizing solution. A first hydraulic cylinder 1 is fixedly arranged vertically on the outside of the impregnating bath 2, and a support frame 6 is fixedly arranged on the telescopic shaft of the first hydraulic cylinder 1. The support frame 6 is located above the impregnating bath 2.

[0024] Two clamping members 11 are fixedly arranged at the bottom of the support frame 6. The two clamping members 11 are symmetrically arranged, and both of the two clamping members 11 are in an "L" shape. "Concave" type limiting plates are fixedly arranged at the opposite ends of the two clamping members 11, and a second hydraulic cylinder 4 is fixedly installed on each of the two clamping members 11. The two second hydraulic cylinders 4 are communicated with the first hydraulic cylinder 1 through pipelines. The telescopic shafts of the two second hydraulic cylinders 4 face each other, and a clamping plate 5 is fixedly arranged on the telescopic shaft of each of the two second hydraulic cylinders 4.

[0025] A winding drum 8 is arranged between the two clamping plates 5. The two ends of the winding drum 8 correspond to the opposite side surfaces of the two limiting plates one by one, and also correspond to the opposite side surfaces of the two clamping plates 5 one by one. The two ends of the winding drum 8 are both placed in a limited manner on the corresponding limiting plates and are in contact and cooperation with the corresponding clamping plates 5.

[0026] When the telescopic shaft of the first hydraulic cylinder 1 contracts, it will drive the telescopic shafts of the two second hydraulic cylinders 4 to extend. When the telescopic shafts of the two second hydraulic cylinders 4 extend, they will push the winding drum 8 to slide under the support of the two limiting plates through the clamping plates 5, so as to clamp and fix the winding drum 8. During the process of the two clamping plates 5 pushing the winding drum 8 to slide, neither of the two limiting plates will be separated from the winding drum 8.

[0027] A coil material 7 is wound around the outer surface of the winding drum 8, and the gravity of the winding drum 8 is greater than the buoyancy force received when the coil material 7 is completely immersed in the glue. A cavity is opened inside the winding drum 8, and a number of through holes 13 are opened on the inner wall of the winding drum 8. The through holes 13 are used to connect the cavity with the external glue. A pump body (not shown in the figure) is fixedly installed on the outer surface of the dipping pool 2. The pumping port of the pump body is connected to the cavity of the winding drum 8 through a pipeline, and the discharging port of the pump body is connected to the dipping pool 2 through a pipeline. The pump body is used to extract the glue and gas in the cavity of the winding drum 8, and after extraction, input the extracted glue and gas into the dipping pool 2 again. Ensure that the cavity of the winding drum 8 is always in a negative pressure state, so as to discharge the gas in the coil material 7 through the adsorption of negative pressure.

[0028] A motor 9 is fixedly installed on the outer surface of one of the clamping members 11. The output shaft of the motor 9 is fixedly provided with a reciprocating lead screw 10. The end of the reciprocating lead screw 10 far from the motor 9 is rotatably connected to the other clamping member 11. And, the central axis of the reciprocating lead screw 10 is parallel to the central axis of the winding drum 8.

[0029] A moving box 12 is threadedly connected to the outer surface of the reciprocating lead screw 10. The top of the moving box 12 is in limiting sliding fit with the bottom of the support frame 6. The moving box 12, the reciprocating lead screw 10 and the ball form a ball screw pair. A first pulley 15 and a second pulley 17 are rotatably arranged inside the moving box 12, and a belt 14 is sleeved between the first pulley 15 and the second pulley 17 for transmission.

[0030] The second pulley 17 is slidably sleeved on the outer surface of the reciprocating lead screw 10. A number of limiting blocks are fixedly provided on the inner wall of the second pulley 17. A number of limiting grooves are opened on the outer surface of the reciprocating lead screw 10. The number of the limiting blocks is equal to and corresponds to that of the limiting grooves one by one. Each limiting block is slidably arranged in the corresponding limiting groove in a limiting manner.

[0031] The first pulley 15 is sleeved on the outer surface of the coil material 7. A pressing plate 16 is fixedly provided on the inner wall of the first pulley 15. The pressing plate 16 is arranged in an arc shape and inclined. Along the axial direction of the first pulley 15, one end of the pressing plate 16 does not contact the outer surface of the coil material 7, and the other end of the pressing plate 16 abuts against the outer surface of the coil material 7.

[0032] The reciprocating lead screw 10 is driven to rotate by the motor 9. The rotation of the reciprocating lead screw 10 will drive the moving box 12 to slide, so as to apply a pressure along the radial direction of the first pulley 15 to the outer surface of the coil 7 through the pressing plate 16. The pressure value received by the coil 7 changes cyclically from large to small or from having to none. The coil 7 makes a breathing radial expansion and contraction under the action of the external pressure and its own elastic force. That is, after the pressure decreases or disappears, the coil 7 radially extends under the action of its own elastic force and returns to its original state.

[0033] Meanwhile, one end of the dipping pool 2 is connected with a connecting pipe 3. A circulating pump (not shown in the figure) is connected to the pipe orifice of the connecting pipe 3 far away from the dipping pool 2. A heating pipe (not shown in the figure) is installed on the circulating pump. One end of the heating pipe is installed with a liquid outlet pipe (not shown in the figure), and the liquid outlet pipe is communicated with the dipping pool 2.

[0034] The circulating pump serves as the power source for driving the circulation of the sizing agent. The heating pipe can heat the sizing agent in circulation to a certain temperature. The liquid outlet pipe can re-output the heated sizing agent to the dipping pool 2. It avoids the reduction of the temperature of the sizing agent after replenishing the sizing agent or standing the sizing agent for a period of time, and tries to prevent the influence on the dipping effect of the coil 7 due to temperature fluctuations.

[0035] By the cyclic change of the gap size in the coil 7, the negative pressure adsorption effect is used to assist the pressing plate 16 to continuously discharge the gas in the coil 7 and suck in the sizing agent, thereby reducing the overall dipping time of the coil 7 and the circulation time of the sizing agent, and greatly improving the dipping efficiency and effect.

[0036] Working principle: When the coil 7 needs to be dipped, the coil 7 is wound around the winding drum 8 in a cylindrical shape. Subsequently, both ends of the winding drum 8 are clamped on two limiting plates. The telescopic shaft of the first hydraulic cylinder 1 is controlled to contract. The telescopic shaft of the first hydraulic cylinder 1 drives the winding drum 8 to approach the inside of the dipping pool 2 through the support frame 6 until the coil 7 is completely immersed in the sizing agent in the dipping pool 2.

[0037] During the contraction of the telescopic shaft of the first hydraulic cylinder 1, the telescopic shafts of the two second hydraulic cylinders 4 extend, thereby pushing the two clamping plates 5 closer to each other. When the coil 7 is completely immersed in the dipping pool 2, the two clamping plates 5 just complete the clamping of the winding drum 8, avoiding the rotation of the winding drum 8 from affecting the subsequent dipping.

[0038] Then the motor 9 is started, and the output shaft of the motor 9 drives the reciprocating lead screw 10 to rotate. The rotation of the reciprocating lead screw 10 will drive the moving box 12 to make a reciprocating linear motion along the central axis of the reciprocating lead screw 10, thereby driving the second pulley 17 to reciprocate on the surface of the reciprocating lead screw 10, and the first pulley 15 to reciprocate on the surface of the winding drum 8.

[0039] During the process of the second pulley 17 sliding on the surface of the reciprocating lead screw 10, it will rotate by itself under the cooperation of the limit block and the limit groove, thereby driving the first pulley 15 to rotate through the belt 14.

[0040] In the initial state, one end of the pressing plate 16 along the axial direction of the first pulley 15 will press the coil material 7, so that the pressing plate 16 applies a pressure along the radial direction of the first pulley 15 to the coil material 7. During the process of the first pulley 15 reciprocatingly sliding on the surface of the winding drum 8, it will rotate by itself under the transmission of the first pulley 15 and the belt 14, thereby driving the pressing plate 16 to move synchronously, and then comprehensively pressing the outer surface of the coil material 7.

[0041] The pressure value received by the surface of the coil material 7 changes cyclically from large to small or from having to disappearing. The coil material 7 makes a breathing-type radial expansion and contraction under the action of the external pressure and its own elastic force. That is, after the pressure decreases or disappears, the coil material 7 radially extends under the action of its own elastic force and returns to its original state.

[0042] During this process, the pump body is started. The pump body is used to extract the glue liquid and gas in the cavity of the winding drum 8, and then input the extracted glue liquid and gas into the dipping pool 2 again after extraction. Ensure that the cavity of the winding drum 8 is always in a negative pressure state, and use the action of negative pressure adsorption to assist the pressing plate 16 to continuously discharge the gas in the coil material 7 and inhale the glue liquid, greatly improving the dipping efficiency and effect.

[0043] Meanwhile, the circulation pump is started. The connecting pipe 3 is used to send the glue liquid to be heated into the interior of the circulation pump. The circulation pump is the power source for driving the circulation of the glue liquid. The heating pipe can heat the glue liquid in circulation to a certain temperature, and the liquid outlet pipe can re-output the heated glue liquid into the dipping pool 2. Avoid the decrease in the temperature of the glue liquid after replenishing the glue liquid or standing the glue liquid for a period of time, and try to prevent the influence of temperature fluctuation on the dipping effect of the coil material 7.

[0044] After the dipping is completed, control the telescopic shaft of the first hydraulic cylinder 1 to extend. The extension of the telescopic shaft of the first hydraulic cylinder 1 will drive the telescopic shafts of the two second hydraulic cylinders 4 to contract, thereby releasing the clamping of the winding drum 8 by the clamping plate 5. When the coil material 7 is away from the inside of the dipping pool 2, the coil material 7 can be spread out.
