Description

Technical Field

[0001] This utility model relates to the field of fluorescent whitening agent slurry technology, and in particular to a vacuum degassing device for fluorescent whitening agent slurry that prevents overflow. Background Technology

[0002] The spill-proof vacuum degassing unit for optical brightener slurries is a highly efficient device specifically designed to remove potential air bubbles and volatile substances from the slurry. This unit plays a crucial role in the production process of optical brighteners. By creating a vacuum environment, it effectively reduces the gas content in the slurry, thereby ensuring the quality and stability of the final product. Furthermore, the advanced technology of this unit optimizes the production process, improves production efficiency, and makes the application of optical brighteners more widespread and reliable.

[0003] In a vacuum environment, dissolved gases in the slurry are released, forming bubbles. If the slurry contains a large amount of gas or tiny bubbles, vacuum degassing may cause these bubbles to aggregate and expand, generating a large amount of foam. The generation of foam hinders the formation of a vacuum environment, preventing the gas from being effectively extracted, thus affecting the degassing effect and resulting in residual bubbles in the slurry. Therefore, there is an urgent need for a leak-proof vacuum degassing device for fluorescent whitening agent slurry to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vacuum degassing device for preventing leakage of fluorescent whitening agent slurry.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vacuum degassing device for fluorescent whitening agent slurry with spill prevention includes a degassing furnace. The top of the furnace's interior is equipped with a degassing mechanism for evacuating the fluorescent whitening agent slurry. The top of the furnace's outer wall is equipped with a processing mechanism for treating the foam in the fluorescent whitening agent slurry. The degassing mechanism includes two first connecting pipes, one end of which is connected to a U-shaped anti-overflow pipe. The other ends of the two U-shaped anti-overflow pipes are connected to a second connecting pipe, with the other ends of the second connecting pipes located at the bottom of the furnace's interior. A conical hood is fixed to the top of the furnace, and a sealing plate is fixed to the bottom of the inner wall of the conical hood. A vacuum pump is installed on the top of the sealing plate. The inlet of the vacuum pump is connected to a connecting conduit, with the other end of the conduit located at the top of the furnace's interior. The outlet of the vacuum pump is connected to a connecting exhaust pipe. The U-shaped anti-overflow pipe can store some material, forming a water seal to prevent gas leakage or entry into the furnace during degassing.

[0007] Preferably, both of the first connecting pipes are equipped with electromagnetic valves, and both U-shaped anti-overflow pipes have fixing plates fixed to their outer walls, with one end of each fixing plate fixedly connected to the outer wall of the degassing furnace.

[0008] Preferably, the top four corners of the outer wall of the conical shroud are fixed with support columns, and the top of the four support columns is fixed with the same baffle. The baffle can prevent external dust from falling into the interior of the conical shroud and causing blockage of the exhaust pipe.

[0009] Preferably, a dustproof mesh is fixed to the bottom of the baffle, and the bottom of the dustproof mesh is fixedly connected to the top of the outer wall of the conical cover.

[0010] Preferably, a liquid level sensor is installed at the bottom of the inner wall of the degassing furnace.

[0011] Preferably, the processing mechanism includes a mounting plate fixed to the top of the outer wall of the degassing furnace. A liquid storage box is provided on the top of the mounting plate. The liquid storage box is filled with defoamer. The top of the liquid storage box is connected to an injection port communicating with its interior. A third connecting pipe is connected to the bottom of the inner wall of the liquid storage box, and the other end of the third connecting pipe is connected to and communicates with the top of the interior of the degassing furnace.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Due to the adoption of a degassing mechanism, the material to be degassed can be transported into the degassing furnace through the first connecting pipe. At this time, some material will remain inside the U-shaped anti-overflow pipe, forming a water seal effect to prevent air leakage during the degassing process. Then, the degassing process can be carried out inside the degassing furnace through a vacuum pump, thereby achieving a good sealing effect during the degassing process, improving the degassing efficiency, and improving the quality of the fluorescent whitening agent slurry. The sealing effect prevents backflow of external air, maintains a stable vacuum environment inside the degassing furnace, and reduces equipment malfunctions caused by air pressure fluctuations.

[0015] 2. Due to the adoption of a processing mechanism, when foam is generated in the fluorescent whitening agent slurry during degassing, the control valve is opened through the control panel, and the defoamer inside the storage box is transported to the inside of the degassing furnace through the third connecting pipe, thereby achieving the effect of eliminating foam, improving the degassing efficiency of the fluorescent whitening agent slurry, improving the purity and stability of the slurry, and enhancing the functionality of the fluorescent whitening agent.

The outlet end of the vacuum pump 403 is connected to a conduit 406. The vacuum pump 403 can be used to evacuate the interior of the degassing furnace 1, which facilitates the degassing process of the fluorescent whitening agent slurry.

[0024] In this utility model, electromagnetic valves 204 are installed inside the two first connecting pipes 2, and fixing plates 202 are fixed on the outer walls of the two U-shaped anti-overflow pipes 201. One end of the two fixing plates 202 is fixedly connected to the outer wall of the degassing furnace 1.

[0025] In this utility model, support columns 402 are fixed at the four corners of the top of the outer wall of the conical cover 103, and the top of the four support columns 402 is fixed with the same baffle 4. The baffle 4 can prevent external dust from falling into the interior of the conical cover 103 and causing blockage to the exhaust pipe 406.

[0027] In this invention, a liquid level sensor 105 is installed at the bottom of the inner wall of the degassing furnace 1.

[0028] In this utility model, the processing mechanism includes a mounting plate 301 fixed to the top of the outer wall of the degassing furnace 1. A liquid storage box 3 is provided on the top of the mounting plate 301. The liquid storage box 3 is filled with defoamer.
