Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of resin materials, and particularly relates to a defoaming device prepared from resin. Background Technique
[0002] In the preparation process of resin materials, defoaming is a crucial link, which directly affects the quality and performance of the final product. At present, the resin defoaming methods widely used in the market mainly include natural static defoaming, heating defoaming, and mechanical vibration defoaming, etc. Among them, natural static defoaming takes a long time and has low efficiency; heating defoaming can accelerate the discharge of bubbles, but may have an adverse effect on some properties of the resin, such as thermal stability; mechanical vibration defoaming improves the efficiency to a certain extent, but there are still problems such as uneven defoaming and difficulty in completely discharging some small bubbles.
[0003] In particular, although the method of negative pressure vacuum pumping is adopted for defoaming in the prior art, the mixing uniformity of the resin during the defoaming process is often ignored, resulting in the defoaming effect being limited by the initial state of the resin, and there are defects such as uneven distribution of the internal components of the resin after defoaming. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a defoaming device prepared from resin to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A defoaming device prepared from resin, including a chassis, a sealed inner tank, and a mixing tank. A vacuum pump is installed on one side inside the chassis. A sealed inner tank is fixedly installed inside the chassis. A vacuum extraction port is arranged at the front end of the top of the sealed inner tank. A door bolt is arranged on one side of the front of the sealed inner tank. A sealed door is installed on the front of the sealed inner tank through a hinge. Two wire frames are installed inside the sealed inner tank. A mixing tank is installed at the rear end inside the sealed inner tank. An installation plate is installed inside the mixing tank. Two mixers are installed on the front of the installation plate.
[0006] The sealed inner tank is used to hold the resin material to be defoamed. By closing the sealed door and clamping the sealed door with the door bolt, the sealed inner tank has good sealing performance to ensure operation in a negative pressure environment. The output end of the vacuum pump is connected to the vacuum extraction port through a pipeline (not shown in the figure due to the use of prior art). Through the operation of the vacuum pump, vacuum pumping operation can be carried out on the sealed inner tank, and the pressure difference is used to prompt the bubbles in the resin to expand rapidly and be discharged. The mixer is located inside the reaction kettle, and the stirring speed can be adjusted according to needs to ensure that the resin is fully mixed during the defoaming process, avoiding uneven distribution of components. At the same time, the shear force generated by stirring also helps to accelerate the rupture and discharge of bubbles. This device combines the dual effects of negative pressure vacuum pumping and stirring, significantly improving the defoaming efficiency and shortening the defoaming time.
[0007] Preferably, a controller is provided above the front of the chassis, and a cabinet door is installed on one side of the front of the chassis through a hinge.
[0008] The controller adopts a PLC control system, which is a common automated control device in the prior art and is a programmable logic control device.
[0009] Preferably, a feed inlet is installed at the rear end of the top of the sealed inner tank, a discharge outlet is provided at the bottom of the sealed inner tank, and control valves are provided on both the feed inlet and the discharge outlet.
[0010] The resin raw material can enter the inside of the sealed inner tank through the feed inlet and be discharged through the discharge outlet, and the setting of the control valve can facilitate the staff to control the opening of the vacuum inside the sealed inner tank or discharge the resin raw material.
[0011] Preferably, the mixer, the vacuum pump and the controller are electrically connected.
[0012] Since the mixer, the vacuum pump and the controller are electrically connected, it is convenient for the staff to control the operation of the mixer and the vacuum pump through the controller, so that the internal electrical equipment of the device can operate in coordination.
[0013] In summary, the present application includes the following beneficial technical effects:
[0014] The utility model can perform vacuum pumping operation on the sealed inner tank through the operation of the vacuum pump, and use the pressure difference to prompt the bubbles in the resin to expand rapidly and discharge. The mixer is located inside the reaction kettle, and the stirring speed can be adjusted according to needs to ensure that the resin is fully mixed during the defoaming process, avoiding uneven distribution of components. At the same time, the shear force generated by stirring also helps to accelerate the rupture and discharge of bubbles. The device combines the dual effects of negative pressure vacuum pumping and stirring, significantly improving the defoaming efficiency and shortening the defoaming time. Description of the Drawings
