Description

Technical Field

[0001] The utility model relates to the technical field of seal ring assembly, and particularly relates to a coupling agent evaporation device. Background Art

[0002] In plastic compounding, a plastic additive that improves the interfacial properties between synthetic resin and inorganic fillers or reinforcing materials, also known as a surface modifier. It can reduce the viscosity of the synthetic resin melt during the plastic processing, improve the dispersion of fillers to enhance the processing performance, and thus enable the product to obtain good surface quality and mechanical, thermal, and electrical properties. Its dosage is generally 0.5 - 2% of the filler dosage. A coupling agent generally consists of two parts: one part is an inorganic group that can act with inorganic fillers or reinforcing materials; the other part is an organic group that can act with synthetic resins. Currently, in the parylene deposition system on the market, the coupling agent is in a liquid state. After the coupling agent evaporates into a gaseous state, the injection of the coupling agent is sucked out by the pressure difference between the inside of the cavity and the inside of the coupling agent bottle. Once there is a pressure difference, the gas-liquid mixed coupling agent that has not been fully evaporated will be sucked out and discarded. In this way, the coupling agent module design is convenient and simple, but it will also cause the coupling agent to enter the cavity in a liquid state rather than a gaseous state, affecting the adhesion of the film layer and also causing pollution to the product. Based on the above defects and deficiencies, it is necessary to improve the existing technology and design a coupling agent evaporation and atomization device for coating equipment.

[0003] Patent No. CN202122623482.4 discloses a coupling agent evaporation and atomization device for coating equipment. This coupling agent evaporation and atomization device for coating equipment includes a coupling agent evaporation tank, a connecting pipe, an electric valve body, a dielectric joint, a coupling agent spray head, a cavity welding joint, and a diffusion plate. The discharge port of the coupling agent evaporation tank is connected to the inlet of the electric valve body through the connecting pipe, the outlet of the electric valve body is connected to the coupling agent spray head through the dielectric joint, the coupling agent spray head is threadedly connected with the cavity welding joint, and a diffusion plate is placed at the connection between the coupling agent spray head and the cavity welding joint. The electric valve body separates the coupling agent evaporation tank and the coupling agent spray head in a switchable manner. The coupling agent evaporation tank is a vacuum cavity structure, and the coupling agent evaporation tank is filled with a coupling agent, and the outer wall of the coupling agent evaporation tank is wrapped with an electric heating module. In this way, the utility model can quickly evaporate, ensure that the coupling agent enters the cavity in a gaseous state, improve the uniformity when the coupling agent is sprayed, enhance the film layer adhesion, and avoid product pollution. By setting the electric valve body, it is necessary to wait for all the coupling agent in the evaporation tank to evaporate before releasing the gas into the coating cavity, which will cause time consumption and reduced efficiency, and suddenly introducing the gas into the coating cavity will cause unstable air pressure. Therefore, the utility model proposes a coupling agent evaporation device. Summary of the Utility Model

[0006] Preferably, the separation component includes a plurality of first U-shaped plates arranged vertically with openings facing the gas distribution box. A second U-shaped plate is arranged between two adjacent first U-shaped plates, and the second U-shaped plate faces the opposite direction of the first U-shaped plate, thus forming a plurality of "hexagon" channels.

[0015] The present utility model will be further described in detail below in conjunction with specific embodiments.

[0016] Embodiment:

[0017] As Figure 1 and Figure 2 shown, a coupling agent evaporation device of the present utility model includes an evaporation tank 1. The evaporation tank 1 is a vacuum cavity structure. The evaporation tank 1 is filled with a coupling agent. The outer wall of the evaporation tank 1 is wrapped with an electric heating module (not marked in the figure). One end of a connecting pipe 2 is connected to the discharge port of the evaporation tank 1. The other end of the connecting pipe 2 is threadedly connected to a cavity welding joint 3 for communicating with a coating cavity. A gas-liquid separation mechanism is connected to the connecting pipe 2. The gas-liquid separation mechanism includes a sealing box 4. The bottom of the sealing box 4 is connected to the evaporation tank 1 through a return pipe 5. A gas distribution box 6 is arranged in the sealing box 4. The gas distribution box 6 communicates with the connecting pipe 2. A plurality of gas distribution holes 7 are arranged on the gas distribution box 6. A separation component is arranged on one side of the gas distribution box 6. The electric heating module evaporates the liquid coupling agent in the evaporation tank 1 into a gas. Under the action of a pressure difference, the gaseous coupling agent enters the gas distribution box 6 along the connecting pipe 2 and is dispersed into the sealing box 4 through the gas distribution holes 7 on the gas distribution box 6. The separation component separates the liquid particles in the gas-liquid mixed coupling agent to ensure that the coupling agent entering the coating cavity is in a gaseous state.

[0018] The separation component includes a plurality of first U-shaped plates 8 arranged vertically with openings facing the gas distribution box. A second U-shaped plate 9 is arranged between two adjacent first U-shaped plates 8. The second U-shaped plate 9 has a direction opposite to that of the first U-shaped plate 8, thereby forming a plurality of "hexagon" channels, so as to extend the passing time of the gas-liquid mixed coupling agent and facilitate the deposition of the liquid coupling agent. Baffle plates 10 are arranged on both the upper and lower sides of the two parallel sides of the first U-shaped plate. The baffle plates 10 form sharp corners to the right. The liquid particles in the gas-liquid mixture are blocked by the baffle plates 10 and gather and slide on their surfaces.

[0019] The horizontal position of the sealing box 4 is higher than that of the evaporation tank 1. The connecting pipe 2 is connected to the bottom of the gas distribution box 6. The aperture of the gas distribution holes 7 gradually increases from bottom to top. The aperture of the bottom gas distribution holes 7 is small and close to the connecting pipe 2, and the gas flow rate is fast. The aperture of the supplementary holes located above is large and the gas flow rate is slow, thereby ensuring the uniformity of gas distribution.

[0020] A diffusion plate (not marked in the figure) for uniformly diffusing the vapor is provided at the connection between the connecting pipe 2 and the cavity welding joint 3.

[0021] A transparent viewing window is provided at the top of the evaporation tank 1 to facilitate observing the evaporation of the coupling agent in the evaporation tank 1.

[0022] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
