Description

Technical Field

[0002] In the process of forming resin matrix composites, the resin needs to be added with components, stirred and mixed, and then combined with reinforcing materials. After reaction and curing, it becomes a product with high strength, low density and special use functions, which is widely used in many fields such as national defense, aerospace, aviation, rail transit, automobiles, ships, chemical industry, etc., and plays a very important and irreplaceable role.

[0034] To enable those skilled in the art to better understand the technical solution of the present application, the present application will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present application.

[0035] A bubble separation unit, the bubble separation unit includes:

[0036] A bubble separation tank 1, the bubble separation tank 1 has a feed pipe 2 and a discharge pipe 3, a bubble separation space is formed inside the bubble separation tank 1, and the cross-sectional area of the bubble separation tank 1 is larger than the cross-sectional area of the feed pipe 2;

[0037] A baffle plate 4, the baffle plate 4 is arranged in the bubble separation space and divides the bubble separation space into a first space and a second space distributed along the arrangement direction from the feed pipe 2 to the discharge pipe 3. Through holes that communicate the first space and the second space are uniformly and densely arranged on the baffle plate 4;

[0038] The resin with bubbles enters the first space from the feed pipe 2 and is separated by the baffle plate 4. The bubbles remain in the first space, and the separated resin enters the second space from the through holes and flows out through the discharge pipe 3.

[0039] Specifically, in this embodiment, as shown in the figure, the present application provides a resin bubble separation device. The resin bubble separation device is arranged in the middle of the equipment for preparing resin. One end of the equipment is connected to a resin pipe for discharging resin. The bubble separation device is arranged in the middle of the resin pipe. The resin bubble separation device includes a bubble separation unit. The bubble separation unit includes a bubble separation tank 1. A feed pipe 2 and a discharge pipe 3 are respectively connected to the bubble separation tank 1. The feed pipe 2 and the discharge pipe 3 are respectively connected to the resin pipe. A bubble separation space is formed inside the bubble separation tank. The resin with bubbles entering from the feed pipe 2 enters the bubble separation space and flows out through the discharge pipe 3. And the cross-sectional area of the bubble separation tank 1 is much larger than the cross-sectional area of the feed pipe 2, which can extend the residence time of the resin with bubbles in the bubble separation tank 1 to separate the bubbles in the resin from the resin as much as possible. A baffle plate 4 is arranged in the bubble separation space. The baffle plate 4 divides the bubble separation space into a first space and a second space arranged along a first direction. The first direction is Figure 1In the horizontal direction, the feeding pipeline 2 is arranged on one side of the first space and communicated with the first space, and the discharging pipeline 3 is arranged on one side of the second space and communicated with the second space. Through holes that uniformly and densely distribute and connect the first space and the second space are provided on the partition board 4. The through holes can be arranged perpendicular to the surface of the partition board 4 or along the first direction, as long as they connect the first space and the second space. The diameter of the through holes corresponds to different filtering requirements and needs to match the process and resin type. The smaller the diameter of the through holes, the better the filtering effect, but the resistance will also increase. Therefore, the determination of the through hole diameter is also very important. In this embodiment, the diameter of the through holes is between 0.5 - 1.5 mm. On the one hand, it can ensure that the resin and bubbles can be separated from each other, and on the other hand, it can also ensure that the resin from which the bubbles have been separated can enter the interior of the second space through the through holes.

[0040] During use, the bubble separation tank 1 is installed in the resin pipeline of the molding equipment. One end of the equipment is connected to a resin pipeline for discharging resin. A bubble separation device is provided in the middle of the resin pipeline. The feeding pipeline 2 and the discharging pipeline 3 of the bubble separation tank 1 are communicated with the resin pipeline. The resin with bubbles produced by the equipment enters the bubble separation tank 1 from the feeding pipeline 2. Since the cross-sectional area of the bubble separation tank 1 is much larger than that of the feeding pipeline 2, the flow rate of the resin entering the first space is significantly reduced, the residence time is prolonged, and the bubbles are difficult to pass through the partition board 4, so they are blocked on one side of the partition board 4, that is, in the first space. At the same time, under the action of buoyancy, the bubbles will continuously float upward and concentrate above the bubble separation tank 1. The resin without bubbles passes through the partition board 4 and enters the interior of the second space, and flows out through the discharging pipeline 3. Through the provision of the bubble separation tank 1 and the partition board 4 in the bubble separation tank 1 in this application, the separation of bubbles and resin is achieved. Through the device described in this application, the bubbles in the resin can be eliminated, so that the quality and performance of the produced product can be guaranteed, and defects such as pinholes, bubbles, resin shortage, and even delamination will not appear in the product, greatly improving the product yield.

[0041] Further, the feeding pipeline 2 is arranged above one side of the bubble separation tank 1, and the discharging pipeline 3 is arranged below the side of the bubble separation tank 1 away from the feeding pipeline 2.

[0042] Specifically, in this embodiment, the feed pipe 2 is located above one side of the bubble separation tank 1, and the discharge pipe 3 is located on the side of the bubble separation tank 1 away from the feed pipe 2 and is below, which is beneficial to the bubbles contained in the resin in the bubble separation tank 1 floating upward. In this way, when the bubbles float upward, the time to reach the top of the bubble separation tank 1 is shorter and the separation effect is better. The discharge pipe 3 is located below, which can ensure that only the resin with the lowest bubble content can be sent to the next process.

[0043] Furthermore, the baffle plate 4 is inclined with respect to the bottom of the bubble separation tank 1, and the distance in the first direction between the side wall of the baffle plate 4 and the side wall of the bubble separation tank 1 relatively close to the feed pipe 2 gradually increases in the direction from the bottom of the bubble separation tank 1 to the top of the bubble separation tank 1. The first direction is the extending direction of the feed pipe 2.

[0044] Specifically, in this embodiment, the baffle plate 4 is inclined with respect to the bubble separation tank 1, as Figure 1 shown. The distance in the first direction between the baffle plate 4 and the left side wall of the bubble separation tank 1 gradually increases in the direction from the bottom of the bubble separation tank 1 to the top of the bubble separation tank 1, that is, gradually increases from bottom to top. This is beneficial to the bubbles in the resin floating upward and can make the upper part of the first space temporarily hold more resin rich in bubbles. In this way, even if the feed pipe 2 cannot continue to transport resin into the bubble separation tank 1, the resin without bubbles in the discharge pipe 3 can be continuously supplied in a short time and will not affect continuous production.

[0045] Furthermore, a defoaming unit is provided above the bubble separation tank 1. The defoaming unit includes:

[0046] A defoaming tank 5, on which a first pipe 6 extending in the second direction is provided. The other end of the first pipe 6 is communicated with the first space, and the second direction is perpendicular to the first direction;

[0047] At one end of the defoaming tank 5 away from the first pipe 6, a second pipe is provided. The end of the second pipe away from the defoaming tank 5 is communicated with a vacuum machine, and the vacuum machine is used to evacuate the inside of the defoaming tank 5;

[0048] A stirring member 8, which is arranged inside the defoaming tank 5 and extends in the second direction. A driver 9 is provided at the top of the defoaming tank 5. The driving end of the driver 9 is connected to the stirring member 8 and is used to drive the stirring member 8 to rotate around a first axis, and the first axis extends in the second direction.

[0049] Specifically, in this embodiment, a defoaming unit is provided above the bubble separation tank 1. The defoaming unit is used to eliminate the bubbles generated in the bubble separation tank 1. The defoaming unit includes a defoaming tank 5. A first pipe 6 extending in the second direction is connected below the defoaming tank 5. The second direction is perpendicular to the first direction. The other end of the first pipe 6 is communicated with the first space, facilitating the bubbles and resin in the first space to enter the interior of the defoaming tank 5 along the first pipe 6. A second pipe is provided at the other end of the defoaming tank 5 away from the first pipe 6. One end of the second pipe away from the defoaming tank 5 is communicated with a vacuum extraction pipe. One end of the vacuum extraction pipe away from the defoaming tank 5 is connected to a vacuum machine. The vacuum machine is used to evacuate the interior of the defoaming tank 5 to eliminate the bubbles inside the defoaming tank 5. A stirring member 8 is further provided inside the defoaming tank 5. The stirring member 8 includes a stirring rod 801 extending in the second direction. A stirring blade 802 is connected to the bottom end of the stirring rod 801. A driver 9 is further provided at the top of the defoaming tank 5. The driver 9 is a driving motor in this embodiment. An electric motor mounting seat 18 is further provided at the top of the defoaming tank 5. The driver 9 is provided on the electric motor mounting seat 18 for fixing the driver 9. The driver 9 has a driving end. The driving end is used to drive the stirring rod 801 to rotate around a first axis, thereby driving the stirring blade 802 to rotate around the first axis. The first axis extends along the second direction. After the resin with bubbles enters the interior of the defoaming tank 5 from the first pipe 6, the driver 9 is turned on, and it will drive the stirring member 8 to stir the resin inside the defoaming tank 5. While stirring, a vacuum extraction process is carried out to make the volume of the bubbles in the resin increase, float to the upper surface of the resin, burst and discharge.

[0050] Further, the defoaming unit further includes a liquid level sensor detection assembly provided inside the defoaming tank 5. The liquid level sensor assembly is used to detect the liquid level height of the resin inside the defoaming tank 5. The liquid level sensor detection assembly is signal-connected to a controller. The controller is signal-connected to the driver 9 and the vacuum machine.

[0051] The liquid level sensor detection assembly is also used to generate a first signal when the liquid level of the resin in the defoaming tank 5 is greater than or equal to a first preset height.

[0052] The controller is used to control the driver 9 to drive the stirring member 8 to rotate and simultaneously control the vacuum machine to evacuate the defoaming tank 5 after receiving the first signal.

[0053] Specifically, in the present embodiment, the degassing unit further comprises a liquid level sensor detection component arranged in the degassing tank 5, the liquid level sensor detection component is used to detect the liquid level height of the resin in the degassing tank 5, the liquid level sensor detection component signal is connected to a controller, the controller signal is connected to the driver 9 and the vacuum machine, the liquid level sensor detection component comprises a lower limit sensor 17 arranged on the side wall of the degassing tank 5 relatively close to one end of the first pipe 6, the distance between the lower limit sensor 17 and the bottom of the degassing tank 5 is a first preset height, when the resin liquid level in the degassing tank 5 is greater than or equal to the first preset height, the lower limit sensor 17 generates a first signal and sends the first signal to the controller, after receiving the first signal, the controller controls the driver 9 to drive the stirring member 8 to rotate, and at the same time controls the vacuum machine to open, and vacuumizes the degassing tank 5 to eliminate bubbles on the resin inside the degassing tank 5.

[0054] Furthermore, a solenoid valve 10 is provided on the first pipeline 6, and the solenoid valve 10 is connected to the controller signal;

[0055] The solenoid valve 10 has a first state and a second state. When in the first state, the first pipeline 6 is connected, and when in the second state, the first pipeline 6 is closed.

[0056] The liquid level sensor detection component is also used to generate a second signal when it is detected that the resin liquid level in the degassing tank 5 is greater than or equal to a second preset height;

[0057] The controller is further configured to control the solenoid valve 10 to switch from the first state to the second state after receiving the second signal.

[0058] Specifically, in this embodiment, a solenoid valve 10 is further provided on the first pipeline 6. The solenoid valve 10 is in signal connection with the controller. Among them, the solenoid valve 10 has a first state and a second state. When in the first state, the first pipeline 6 is in a conducting state, and the degassing tank 5 is communicated with the first space. When in the second state, the first pipeline 6 is in a closed state, and the degassing tank 5 is relatively closed to the first space. The liquid level sensor detection assembly further includes an upper limit sensor 16 disposed in the degassing tank 5 at a second preset height from the bottom of the degassing tank 5. When the resin liquid level height in the degassing tank 5 is greater than or equal to the second preset height, the upper limit sensor 16 generates a second signal and sends the second signal to the controller. After receiving the second signal, the controller controls the solenoid valve 10 to switch from the first state to the second state. At this time, the degassing tank 5 and the first space are relatively closed to each other. Then, the resin in the degassing tank 5 continues to be degassed for a preset time. When the cumulative degassing time reaches the preset time, the vacuum pumping is stopped, and the resin with the bubbles removed flows to the discharge pipeline 3 and enters the next process together with the resin inside the discharge pipeline 3.

[0059] Further, a buoyancy sensor 11 is also provided in the first space. The buoyancy sensor 11 is in signal connection with the controller;

[0060] When the value of the buoyancy sensor 11 is less than or equal to the first buoyancy threshold, a third signal is generated. The controller is further configured to control the solenoid valve 10 to switch from the second state to the first state and control the vacuum machine to evacuate the inside of the degassing tank 5 according to the third signal;

[0061] When the value of the buoyancy sensor 11 is greater than or equal to the second buoyancy threshold, a fourth signal is generated. The controller is further configured to control the solenoid valve 10 to switch from the first state to the second state according to the fourth signal.

[0062] Specifically, in this embodiment, a buoyancy sensor 11 is further provided in the first space. The buoyancy sensor 11 is used to detect the density of the resin inside the first space. When there are bubbles in the resin, the bubbles will reduce the density of the resin because the inside of the bubbles is filled with gas, and the density of the gas is lower than that of the resin. When the bubble content in the resin increases, the buoyancy received by the buoyancy sensor 11 decreases. When the value of the buoyancy sensor 11 is less than or equal to a preset first buoyancy threshold, the buoyancy sensor 11 will generate a third signal and send the third signal to the controller. When the controller receives the third signal, it will control the solenoid valve 10 to switch from the second state to the first state. At the same time, the controller will control the vacuum machine to start and perform a vacuum treatment on the inside of the degassing tank 5, so that the resin with bubbles inside the bubble separation tank 1 enters the inside of the degassing tank 5 through the first pipeline 6, and a vacuum treatment is performed on the resin and bubbles inside the degassing tank 5, thereby accelerating the rupture of the bubbles. When the value of the buoyancy sensor 11 is greater than or equal to a preset second buoyancy threshold, the buoyancy sensor 11 will generate a fourth signal and send the fourth signal to the controller. When the controller receives the fourth signal, it will control the solenoid valve 10 to switch from the first state to the second state.

[0063] Further, the degassing unit further includes a temperature sensor 12 provided in the degassing tank 5 and a heating element 13 provided below the degassing tank 5. The temperature sensor 12 is signal-connected to the controller, and the controller is signal-connected to the heating element 13;

[0064] The temperature sensor 12 is used to generate a first temperature signal when the resin temperature in the degassing tank 5 is greater than or equal to a first temperature threshold. The controller is used to control the heating element 13 to stop heating after receiving the first temperature signal;

[0065] The temperature sensor 12 is further used to generate a second temperature signal when the resin temperature in the degassing tank 5 is less than or equal to a second temperature threshold. The controller is further used to control the heating element 13 to start heating after receiving the second temperature signal.

[0066] Specifically, in this embodiment, a temperature sensor 12 is further provided inside the degassing tank 5, and a heating element 13 is further provided below the degassing tank 5. The heating element 13 is used to heat the resin to increase the degassing rate of the resin. The temperature sensor 12 is signal-connected to the controller, and the controller is signal-connected to the heating element 13. The temperature sensor 12 is used to detect the temperature of the resin inside the degassing tank 5 and generate a corresponding temperature signal. When the temperature of the resin is greater than or equal to the set first temperature threshold, the temperature sensor 12 generates a first temperature signal. After receiving the first temperature signal, the controller controls the heating element 13 to stop heating the resin inside the degassing tank 5. When the temperature of the resin reaches less than or equal to the set second temperature threshold, the temperature sensor 12 generates a second temperature signal. After receiving the second temperature signal, the controller controls the heating element 13 to start heating the resin inside the degassing tank 5.

[0067] Further, a zero-level sensor 14 is further provided at the bottom end inside the degassing tank 5. The zero-level sensor 14 is signal-connected to the controller. The zero-level sensor 14 is used to detect and send a zero-level signal when there is no resin in the degassing tank 5. After receiving the zero-level signal, the controller controls the heating element 13 to stop heating.

[0068] Specifically, in this embodiment, a zero-level sensor 14 is further provided at the bottom of the degassing tank 5. The zero-level sensor 14 is signal-connected to the controller. The zero-level sensor 14 is used to detect whether there is still resin in the degassing tank 5. When the zero-level sensor 14 detects that there is no resin inside the degassing tank 5, it sends a zero-level signal to the controller. After receiving the zero-level signal, the controller controls the heating element 13 to stop heating.

[0069] Further, a heat-insulating layer 15 is sleeved outside the degassing tank 5.

[0070] Specifically, in this embodiment, a heat-insulating layer 15 is sleeved outside the degassing tank 5, which can reduce heat loss.

[0071] Working principle: When the third pipeline 19 is working, the resin with bubbles enters the first space from the feed pipeline 2. Because the cross-sectional area of ​​the bubble separation tank 1 is much larger than the cross-sectional area of ​​the feed pipeline 2, the flow rate of the resin entering the first space is significantly reduced, and the resin stays in the first space for a longer time. It is difficult for the bubbles to pass through the baffle plate 4, so they are blocked on one side of the baffle plate 4, that is, in the first space. At the same time, as the resin in the first space is continuously accumulated, the bubbles inside the resin continue to rise, and the buoyancy sensor 11 will measure the density of the resin in real time. When the value of the buoyancy sensor 11 is less than or equal to the first buoyancy threshold, the buoyancy sensor 11 will A third signal is sent out. After receiving the third signal, the controller controls the solenoid valve 10 to switch from the second state to the first state, and at the same time controls the vacuum machine to vacuum the degassing tank 5, and sucks the resin in the bubble separation tank 1 and the bubbles thereon into the degassing tank 5 to eliminate the bubbles. When the lower limit sensor 17 detects that the resin liquid level is greater than or equal to the first preset height, a first signal is generated. After receiving the first signal, the controller controls the driver 9 to drive the stirring member 8 to rotate, and at the same time continues to vacuum the degassing tank 5. In the process of vacuuming the resin, the temperature sensor 1 at the bottom of the degassing tank 5 2 will judge the temperature of the resin in real time and generate a temperature signal, and control the heating plate 13 to start or stop heating according to the temperature signal, and the resin liquid level in the degassing tank 5 continues to rise. When the upper limit sensor 16 detects that the resin liquid level in the degassing tank 5 is greater than or equal to the second preset height, it generates a second signal. After receiving the second signal, the controller will control the solenoid valve 10 to switch from the first state to the second state, so that the resin in the bubble separation tank 1 will not continue to rise into the degassing tank 5, the driver 9 continues to stir the resin in the degassing tank 5, the heating element 13 also continues to heat, and at the same time performs a vacuum treatment, so that the bubbles are not The degassing tank 5 is provided with a third pipe 19 at the bottom end thereof, and the resin coming out of the third pipe 19 and the resin flowing out of the second space of the degassing tank 5 can be directly used for production. A fourth pipe is provided at the top of the degassing tank 5, and a three-position one-way control valve is provided at one end of the fourth pipe away from the degassing tank 5. A vacuum machine, an air pipe connected to the outside, and a device for conveying compressed air are respectively connected at one end of the fourth pipe away from the degassing tank 5. When the resin inside the degassing tank 5 is emptied, the solenoid valve 10 is switched from the first state to the second state. At the same time, the three-position one-way control valve connects the degassing tank 5 with the air pipe to unload the pressure inside the degassing tank 5.When the resin enters the resin storage tank through the third pipeline 19, first, the three-way control valve connects the degassing tank 5 to the atmosphere through the air pipeline to unload the vacuum inside the degassing tank 5. Then, the degassing tank 5 is connected to the device for conveying compressed air to convey compressed air into the degassing tank 5, so that the resin inside the degassing tank 5 flows back into the resin storage tank under the dual action of its own gravity and pressure. The resin liquid level in the degassing tank 5 continuously decreases. When the zero-position sensor 14 detects that there is no resin inside the degassing tank 5, it will send a zero-position signal. After receiving the zero-position signal, the controller will control the heating element 13 to stop heating the degassing tank 5, and the three-way control valve will connect the degassing tank 5 to the atmosphere through the air pipeline to unload the pressure inside the degassing tank 5;

[0072] During the working process of the bubble separation device of the present application, operators do not need to contact the resin, the degassing tank 5, and the bubble separation tank 1, which is safe and reliable. At the same time, when heated to the set temperature, heating can be automatically stopped, and there is no risk of high-temperature failure of the resin. When the resin reaches the upper limit sensor 19 (that is, when the liquid level height is greater than or equal to the first preset height), the first pipeline 6 is in a closed state to prevent the resin inside the degassing tank 5 from overflowing, with a high safety level. Moreover, the device described in the present application has a wide range of applications. According to different types of resins produced, the viscosities of the resins are different, and the pore diameters of the baffle plates 4 are also different. According to different production outputs, the resin flow rates are also different. When the output is large, the required degassing capacity will also increase. In this case, products with a greater degassing capacity and a larger volume can be selected to meet the needs of different production capacities. A heat insulation layer 15 is provided outside the degassing tank 5, which can reduce heat dissipation and is conducive to energy conservation. The entire degassing process of the resin is carried out in a closed container and pipeline, without exposure and pollution, and no volatile substances are generated, which is beneficial to environmental protection.
