Filtering-separation liquid seal container

Abstract

The invention discloses a filtering-separation liquid seal container. The filtering-separation liquid seal container comprises a barrel, wherein an upper end enclosure which is provided with a blow-down pipe and a feeding pipe is arranged at the top part of the barrel, a lower end enclosure which is provided with a discharge pipe is arranged at the bottom of the barrel, a separation cavity is arranged in the middle of the barrel, the feeding pipe is inserted into the separation cavity, and a filtering basket is arranged at the bottom of the feeding pipe. The filtering-separation liquid seal container has the advantages that firstly, the filtering basket is arranged below the feeding pipe and used for filtering major-diameter polymers; secondly, the feeding pipe is arranged in the separation cavity and has a liquid sealing function; thirdly, a mesh enclosure is arranged outside a notch and used for further filtering polymers; fourthly, the mesh enclosure is arranged on a side plate by a mesh enclosure buckle and is convenient to take out without affecting production; fifthly, the filtering basket is provided with a traction connecting rod and a hand-pulling connecting rod and is convenient to take out for cleaning; sixthly, a slide way is arranged in the separation cavity and the filtering basket is convenient to take out.

Description

technical field [0001] The invention relates to chemical equipment, in particular to a filtering and separating liquid-sealed container. Background technique [0002] Polybutylene terephthalate (PBT) is a linear saturated polyester resin. In terms of chemical structure, it is a homologue of polyester resin polyethylene terephthalate (PET). It was developed in 1949 by German scientists first made it. In 1970, CELANESE Company in the United States first developed a new type of PBT thermoplastic polyester engineering plastic. This plastic has high mechanical strength, heat resistance, good dimensional stability, creep resistance, and excellent performance. Electrothermal performance and chemical stability, so it has a large application space. In the 1990s, with the rise of the automobile industry and the electronics industry, it has been widely used. Now it has become one of the top five engineering plastics, with an annual growth rate of 8 % or so, it is now widely used in op...

AI Technical Summary

Problems solved by technology

[0003] In the production process of polybutylene terephthalate (PBT), the butylene glycol from the scraper condenser contains a large amount of oligomers, which need to be filtered, separated and other processes, and now commonly used The means are generally implemented by series connection of equipment such as filters, separators, and liquid seal tanks, each of which completes a process and function. Each equipment needs to be equipped with a large number of auxiliary equipment such as cylinders, heads, joints, and supports. These auxiliary equipment are combined together, there are many equipments, occupy a large area, and the failure rate is high. If one of the parts or equipment fails, other equipment can only be shut down.
