Problems solved by technology

[0005] The Chinese patent application No. 201621438194.4 discloses a degassing mechanism for vehicle-mounted resin machines, which adopts a stirring method for degassing. Because the resin is a high-viscosity liquid, and the amount of resin is large, 500 degassing each time -1000kg, there is a disadvantage that the tiny bubbles inside the resin are difficult to escape

Embodiment 1

[0039] Such as Figure 2-3As shown, the present invention is a kind of defoaming device, comprising a tank body, the tank body includes a side wall 21, the upper part of the tank body is provided with a material inlet, and the tank body is provided with a spinner for accepting materials and a plurality of bowls below the spinner. Degassing components arranged in sequence, the degassing components include an upper partition 22 and a lower partition 24 positioned below the upper partition 22, the upper partition 22 is provided with an upper through hole 221, and the lower partition 24 There is a channel for the material to pass between the side wall 21; the upper partition 22 is inclined upward, and the lower partition 24 is inclined downward, and at least a part of the lower partition 24 is located directly below the upper through hole 221 , the material falls on the upper partition 22 below after passing through the channel. Such as Figure 2-3 As shown, the upper partition ...

Embodiment 2

[0046] Such as figure 1 As shown, a degassing system includes a degassing device 2, and also includes a vacuum pump 1 connected to the degassing device 2 through a pipeline, a heater 4 and a valve arranged on the pipeline, and the material enters after being heated by the heater 4 The defoaming device 2 and the vacuum pump 1 keep the inside of the defoaming device 2 in a negative pressure state, and the material degassed by the defoaming device 2 enters the finished product tank 11 for storage.

[0047] It also includes a pump for re-pumping the material degassed by the degassing device 2 into the degassing device 2, corresponding pipelines and valves.

[0048] The raw material tank 6, the heater 4 and the defoaming device 2 are connected in sequence through pipelines, a solenoid valve III5 is set between the raw material tank 6 and the heater 4, and a solenoid valve I3 is set between the heater 4 and the defoaming device 2. The discharge port of the shown defoaming device 2 ...

Embodiment 3

[0056] A defoaming method, comprising the steps of first heating the material, and then adding the heated material into the defoaming device 2, keeping the defoaming device 2 in a negative pressure environment, the material is brought into the spinner, and the defoamer is thrown During the rotation of the disc, the material is dropped onto the defoaming assembly, and the material passes through the upper partition 22 and the lower partition 24 of the defoaming assembly in turn, and flows downward in a zigzag shape under the action of gravity, and the material is in the film state, the air bubbles in the material are removed.

Abstract

The invention relates to a defoaming apparatus, system, and method. The defoaming apparatus comprises a tank, which comprises a lateral wall. The upper part of the tank is provided with a material inlet. A projecting disc for bearing materials and a plurality of defoaming assemblies, which are arranged under the projecting disc in sequence, are arranged in the tank. Each defoaming assembly comprises an upper partition plate and a lower partition plate, which is under the upper partition plate. An upper through hole is arranged in the upper partition plate. A channel for delivering materials isarranged between the lower partition plate and a lateral wall. The upper partition plate is upwards inclined. The lower partition plate is downwards inclined. At least a part of the lower partition plate is right under the upper through hole. After a material passes through the channel, the material falls on the upper partition plate under the channel. Resin is always in a thin film state, no resin is stored, defoaming is carried out when resin is always in a thin film state; the problem that foams in resin are hard to remove is solved; after defoaming, the foam content of the resin is very low; and the problems such as whitening, bubbling, and the like, in blade infusion are solved.

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to a defoaming device, system and method. Background technique [0002] Wind power generation is an important development direction of the country's new energy industry in recent years. Through wind power generation equipment, the natural wind energy is converted into electrical energy, realizing the development and utilization of clean energy in the country. The main components of wind power generation equipment are: fan blades, generators (including devices), steering devices (tail fins), towers, speed limit safety mechanisms, and energy storage devices. [0003] Among them, the quality of fan blades has a major impact on the power generation system. At present, the mainstream material of fan blades on the market is FRP. An important factor in the quality of FRP blades is the core material of the blades—the air bubbles in the epoxy resin of the blades. Exc...
