Description

Technical Field

[0001] This utility model relates to the field of industrial naphthalene processing technology, specifically a vacuum filtration device for industrial naphthalene separation. Background Technology

[0002] Naphthalene, also known as naphthalene, is a colorless, lustrous, flaky crystal. It is the most important polycyclic aromatic hydrocarbon in industry and can be used to produce phthalic anhydride, dye intermediates, rubber additives, and pesticides. After further purification to remove impurities and desulfurization, industrial naphthalene can be obtained as high-purity refined naphthalene.

[0003] In the process of processing industrial naphthalene, a vacuum filtration device is required for separation. However, during prolonged use, the filter screen inside the vacuum filtration device may become clogged, reducing the filtration efficiency of the industrial naphthalene and decreasing the overall processing efficiency. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a vacuum filtration device for industrial naphthalene separation, thereby resolving the issues raised in the background section.

[0005] To achieve the above objectives, this utility model proposes a vacuum filtration device for industrial naphthalene separation, comprising a cylinder, a vacuum pump on one side of the cylinder, a pressure gauge on the top of the cylinder, and a filtration assembly on the top of the cylinder;

[0006] The filter assembly includes a filter barrel fixedly connected to the center of the top of the cylinder. A first connecting rod is rotatably connected to the center of the inner wall of the filter barrel. Multiple scrapers are fixedly connected at equal intervals to the outer wall of the first connecting rod. A cleaning brush is fixedly connected to the bottom of each scraper. A collar is fixedly connected to both sides of the inner wall of the filter barrel. A first screen is embedded in the inner wall of one collar, and a second screen is embedded in the inner wall of the other collar.

[0007] In one example, a base is fixedly connected to the bottom of the first connecting rod, and support frames are fixedly connected to both sides of the outer wall of the base. Multiple levers are fixedly connected at equal distances to one side of the two support frames.

[0008] In one example, a motor is fixedly connected to the top of the filter barrel, and one end of the first connecting rod passes through the top of the filter barrel and is fixedly connected to the output end of the motor.

[0009] In one example, a feed pipe is fixedly connected to one side of the top of the filter barrel, and a discharge pipe is fixedly connected to one side of the outer wall of the barrel.

[0010] In one example, a switch panel is provided on one side of the cylinder, and the surface of the switch panel is provided with a vacuum pump switch and a motor switch. The vacuum pump and the motor are electrically connected through an external power supply.

[0011] The vacuum filtration device for industrial naphthalene separation proposed in this utility model can bring the following beneficial effects:

[0012] This vacuum filtration device for separating industrial naphthalene comprises a first connecting rod, a scraper, a cleaning brush, a collar, a first screen, and a second screen, all located inside the filter barrel. During use, the industrial naphthalene undergoes preliminary filtration through the first screen and then falls onto the second screen for secondary filtration. Driven by a motor, the cleaning brush scrapes the surfaces of both screens, preventing excessive accumulation of industrial naphthalene and improving the efficiency of the filtration process.

[0013] This vacuum filtration device for separating industrial naphthalene, through a base, support frame, and lever located at the bottom of the first connecting rod, allows the filtered industrial naphthalene to fall into the cylinder during use. Then, driven by a motor, the lever rotates to agitate the industrial naphthalene inside, preventing clumping that would occur if left undisturbed, thus improving the quality of the processed industrial naphthalene.
