DETAILED DESCRIPTION
[0034] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is described in detail below in conjunction with the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present application.
[0035] A bubble separation unit, the bubble separation unit comprising:
[0036] A bubble separation tank 1, wherein the bubble separation tank 1 has a feed pipe 2 and a discharge pipe 3, a bubble separation space is formed in the bubble separation tank 1, and the cross-sectional area of the bubble separation tank 1 is greater than the cross-sectional area of the feed pipe 2;
[0037] a baffle plate 4, wherein the baffle plate 4 is disposed 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, and the baffle plate 4 is provided with uniformly distributed through holes connecting the first space with the second space;
[0038] The resin with bubbles enters the first space from the feed pipe 2 and is separated by the baffle plate 4 , and the bubbles remain in the first space. The separated resin enters the second space from the through hole and flows out from the discharge pipe 3 .
[0039] Specifically, in this embodiment, as shown in the figure, the present application provides a resin bubble separation device, which is arranged in the middle of a device for preparing resin, one end of the device is connected to a resin pipe for resin to flow out, and the bubble separation device is arranged in the middle of the resin pipe, and the resin bubble separation device includes a bubble separation unit, and the bubble separation unit includes a bubble separation tank 1, and a feed pipe 2 and a discharge pipe 3 are respectively connected to the bubble separation tank 1, and the feed pipe 2 and the discharge pipe 3 are respectively connected to the resin pipe, and a bubble separation space is formed inside the bubble separation tank, and the resin with bubbles entering from the feed pipe 2 enters the bubble separation space and flows out from 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, so as to eliminate the bubbles in the resin and separate the resin as much as possible, and a baffle plate 4 is arranged in the bubble separation space, and the baffle plate 4 divides the bubble separation space into a first space and a second space arranged along a first direction, and the first direction is Figure 1In the horizontal direction, the feed pipe 2 is arranged on one side of the first space and is connected with the first space, the discharge pipe 3 is arranged on one side of the second space and is connected with the second space, and the baffle plate 4 is provided with uniformly distributed through holes connecting the first space with the second space. The through holes can be arranged perpendicular to the surface of the baffle plate 4 or along the first direction, as long as the first space is connected with the second space, the diameter of the through holes corresponds to different filtration requirements and needs to be matched with the process and resin type. The smaller the diameter of the through holes, the better the filtration effect, but the resistance will also increase, so the determination of the through hole diameter is also very important. In this embodiment, the diameter of the through hole is between 0.5-1.5mm, which can ensure that the resin and bubbles can be separated from each other on the one hand, and on the other hand, it can ensure that the resin from which the bubbles are separated can enter 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 the resin pipeline for resin to flow out. A bubble separation device is provided in the middle of the resin pipeline. The feed pipeline 2 and the discharge pipeline 3 of the bubble separation tank 1 are connected to the resin pipeline. The resin with bubbles prepared by the equipment enters the bubble separation tank 1 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, the residence time is prolonged, and 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, bubbles will continue to float up under the action of buoyancy and concentrate above the bubble separation tank 1. The resin without bubbles enters the second space through the baffle plate 4 and flows out through the discharge pipe 3. The present application is provided with a bubble separation tank 1 and a baffle plate 4 in the bubble separation tank 1 to separate the bubbles from the resin. The device described in the present application can eliminate the bubbles in the resin, so that the quality and performance of the manufactured products can be guaranteed, and there will be no defects such as pinholes, bubbles, lack of resin or even stratification in the product, which greatly improves the product yield.

In this way, when the bubbles float up, 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 relative to the bottom of the bubble separation tank 1, and the distance along 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 from the bottom of the bubble separation tank 1 to the top of the bubble separation tank 1, and the first direction is the extension direction of the feed pipe 2.
[0044] Specifically, in this embodiment, the baffle plate 4 is arranged obliquely relative to the bubble separation tank 1, such as Figure 1 As shown, the distance between the baffle plate 4 and the left side wall of the bubble separation tank 1 along the first direction gradually increases 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, which is conducive to the floating of bubbles in the resin and enables more bubble-rich resin to temporarily stay in the upper part of the first space. In this way, even if the feed pipe 2 cannot continue to transport resin into the bubble separation tank 1, the bubble-free resin in the discharge pipe 3 can also be continuously supplied in a short time, and will not affect continuous production.
[0045] Furthermore, a degassing unit is provided above the bubble separation tank 1, and the degassing unit comprises:

The driver 9 is arranged on the motor mounting seat 18 for fixing the driver 9. The driver 9 has a driving end, and the driving end is used to drive the stirring rod 801 to rotate around the first axis, thereby driving the stirring blade 802 to rotate around the first axis. The first axis extends along the second direction. When the resin with bubbles enters the degassing tank 5 from the first pipe 6, the driver 9 is turned on, which will drive the stirring member 8 to stir the resin in the degassing tank 5, and vacuum treatment is performed while stirring, so that the volume of the bubbles in the resin increases, floats to the upper surface of the resin, breaks and is discharged.

[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 the present embodiment, a solenoid valve 10 is further provided on the first pipe 6, and the solenoid valve 10 is connected to the controller signal, wherein the solenoid valve 10 has a first state and a second state, when in the first state, the first pipe 6 is in a conducting state, and the degassing tank 5 is connected to the first space, and when in the second state, the first pipe 6 is in a closed state, and the degassing tank 5 is relatively closed to the first space, and the liquid level sensor detection component also includes an upper limit sensor 16 arranged in the degassing tank 5 at a second preset height from the bottom of the degassing tank 5. When the resin liquid in the degassing tank 5 When the surface height is greater than or equal to a 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 in a closed state relative to each other, and 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 is stopped, and the resin from which the bubbles have been removed flows into the discharge pipe 3, and enters the next process together with the resin inside the discharge pipe 3.
[0059] Furthermore, a buoyancy sensor 11 is provided in the first space, and the signal of the buoyancy sensor 11 is connected to 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, and the controller is further used to control the solenoid valve 10 to switch from the second state to the first state according to the third signal, and control the vacuum machine to evacuate the interior of the degassing tank 5;
[0061] When the value of the buoyancy sensor 11 is greater than or equal to the second buoyancy threshold, a fourth signal is generated, and the controller is further used 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, and the buoyancy sensor 11 is used to detect the density of the resin in the first space. When there are bubbles in the resin, the bubbles will reduce the density of the resin because the bubbles are filled with gas, and the density of the gas is lower than that of the resin.

[0066] Specifically, in the present embodiment, a temperature sensor 12 is further provided in 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 signal is connected to the controller, and the controller signal is connected to the heating element 13. The temperature sensor 12 is used to detect the resin temperature inside the degassing tank 5 and generate a corresponding temperature signal. When the temperature of the resin is greater than or equal to a 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 a value less than or equal to a 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] Furthermore, a zero position sensor 14 is provided at the bottom end of the degassing tank 5. The signal of the zero position sensor 14 is connected to the controller.

[0068] Specifically, in the present embodiment, a zero position sensor 14 is further provided at the bottom of the degassing tank 5, and the zero position sensor 14 is connected to the controller by a signal. The zero position sensor 14 is used to detect whether there is still resin in the degassing tank 5. When the zero position sensor 14 detects that there is no resin in the degassing tank 5, it will send a zero position signal to the controller.

[0069] Furthermore, a heat-insulating layer 15 is also provided outside the degassing tank 5 .
[0070] Specifically, in this embodiment, a heat-insulating layer 15 is further provided on the outside of the degassing tank 5 to 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 containing tank through the third pipe 19, the three-position one-way control valve will first connect the degassing tank 5 with the atmosphere through the air pipe to unload the vacuum inside the degassing tank 5, and then connect the degassing tank 5 with 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 to the resin containing tank under the dual effects of its own gravity and pressure, and the resin liquid level in the degassing tank 5 is continuously reduced. When the zero position sensor 14 detects that there is no resin inside the degassing tank 5, it will send out 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-position one-way control valve will connect the degassing tank 5 with the atmosphere through the air pipe to unload the pressure inside the degassing tank 5;
[0072] The bubble separation device of the present application does not require operators to contact the resin, the degassing tank 5 and the bubble separation tank 1 during operation, which is safe and reliable. At the same time, when heated to the set temperature, the heating can be automatically stopped, and the resin will not be in danger of high-temperature failure. When the resin reaches the upper limit sensor 19 (that is, the liquid level is greater than or equal to the first preset height), the first pipe 6 is in a closed state to prevent the resin in the degassing tank 5 from overflowing. The safety level is high, and the device described in the present application has a wide range of applications. Depending on the type of resin produced, the viscosity of the resin is different, the aperture of the baffle 4 is also different, and the flow rate of the resin is also different depending on the production output. When the output is large, the required degassing capacity will also increase. In this way, products with greater degassing capacity and larger capacity can be selected to meet the needs of different production capacities. An insulation layer 15 is provided on the outside of the degassing tank 5 to reduce heat loss and save energy. The entire degassing process of the resin is carried out in a closed container and pipeline, and will not be exposed and polluted, and will not produce volatile substances, which is beneficial to environmental protection.
