Naphthalene tank breathing valve enhanced cooling crystallization scraping device

Abstract

The invention relates to a strengthened cooling crystal scraping device for a naphthalene tank breather valve. The strengthened cooling crystal scraping device comprises screen plates, scrapers, a cylinder, a main shaft, a gear ring, a gear and a speed reduction motor. A needle bearing is arranged at the bottom of the cylinder. The main shaft is arranged in the needle bearing. The screen plates and the scrapers are arranged on the main shaft in a staggered and sleeving manner to form a multi-layer structure. An embedding structure is arranged between each scraper and the main shaft. A clamping structure is arranged between the edge of each screen plate and the inner wall of the cylinder. The speed reduction motor is arranged on the outer wall of the cylinder, the gear is arranged on a speed reduction motor shaft and engaged with the gear ring, and the gear ring and the scraper on the topmost layer are connected into a whole and installed on the main shaft. The strengthened cooling crystal scraping device is simple in structure and easy to achieve, the strengthened cooling crystal scraping device only needs to be installed between the breather valve and the top of a naphthalene storage tank, naphthalene tank breather valve crystallizing blockage, harmful gas emission and flash explosion can be effectively prevented, and it is guaranteed that the breather valve on the top of the naphthalene tank can normally work around the clock.

Description

Technical field [0001] The invention relates to a naphthalene tank breathing valve enhanced cooling and crystallization scraping device, in particular, is an additional equipment for the naphthalene tank breathing valve, installed between the naphthalene tank and the breathing valve, used for naphthalene gas to enhance cooling and crystallization and scraping back to The device in the tank. Background technique [0002] Coal tar is one of the important products of the coking industry, and many products and raw materials of coking plants contain a certain proportion of naphthalene or naphthalene compounds. At present, for storage tanks containing liquid naphthalene, the temperature in the tank is generally between 80°C and 90°C, and there is a large amount of naphthalene vapor between the naphthalene liquid level and the tank top, which will follow the breathing valve on the top of the naphthalene storage tank. The tank overflows. The crystallization temperature of naphthalene i...
