Filter pressing device for producing amino acid

Abstract

The invention discloses a filter pressing device for producing amino acid. The filter pressing device comprises a pressing head and a funnel; the inner diameter of the funnel is matched with the outer diameter of the pressing head; the pressing head can be pressed into the funnel; and one group of counter bores are uniformly formed in the bottom of the pressing head. Compared with the prior art, a whole filter pressing process has a certain air pressure gap all the time through the design of the pressing head and the counter bores on the funnel in the aspect of manufacturing; the overflowing, even splashing of an intermediate are not caused and the production efficiency of filter pressing can also be effectively controlled, so that the peripheral environment of a filter pressing field is protected; and meanwhile, a biological film is matched with the filter pressing in the design so that the grain diameter of the intermediate subjected to filter pressing is reduced, a foundation is laid for rapidly entering a next path of fine machining process and the quality of products is also ensured.

Description

[0001] technical field [0002] The invention belongs to the field of chemical industry, and in particular relates to a pharmaceutical intermediate, and mainly provides a pressure filter device for the production of amino acids. Background technique [0003] In the production of amino acids, a series of pretreatments, such as pressure filtration and filtration, are required before the next process can be performed. In the traditional method, the amino acid is generally placed in a larger ascending container first, and the intermediate is pressed into the descending container by controlling the pressure head through the machine. This has many disadvantages. For example, if the pressure is too high or the amino acid in the upward container is too full, it will easily cause overflow during the pressurization process, which may lead to waste of amino acid and even pollute the surrounding production environment. Moreover, if the container and the pressure head are not matched, ...

Problems solved by technology

This has many disadvantages. For example, if the pressure is too high or the amino acid in the upward container is too full, it will easily cause overflow during the pressurization process, which may cause waste of amino acid or even pollute the surrounding production environment.

Moreover, if the container and the pressure head are not matched, it will easily cause the intermediate with larger particles to enter the next process during compression, which will affect the quality of the entire product.
