Multilayered filtering equipment with backwashing device

Abstract

The invention discloses multilayered filtering equipment with a backwashing device. The external structure of the multilayered filtering equipment mainly comprises a barrel, a feeding pipe, a discharge pipe, a support and a waste residue outlet, wherein a three-layered filter material layer is arranged inside the barrel, in which a perlite layer serves as the lower layer, a quartz sand layer serves as the interlayer, and an activated carbon layer serves as the top most layer; the particle size of the filter material is gradually reduced to increase the filtration efficiency. In the multilayered filtering equipment disclosed by the invention, a control valve is used to switch between the filtering function and the backwashing function; during the filtering process, the material liquid is fed from a lower feeding hole and discharged from an upper discharge hole; during the backwashing process, the material liquid is fed from the upper feeding hole and discharged from the lower discharge hole; the fed material is uniformly distributed through a distribution pipe and the baffling action of a baffle plate, and meanwhile the impact on the filter material when the fed material flows too much can be relieved; the baffle plate serves as a reversed U shape, so as to effectively realize the baffling effect; an access hole is formed in the side of the barrel to bring convenience to inspection; an overflow weir is used to discharge the material, so as to facilitate the discharged material to be more uniform.

Description

technical field [0001] The invention relates to a biopharmaceutical raw material filtering device, in particular to a multi-layer filtering device with backwashing function. Background technique [0002] In recent years, with the rapid development of modern biotechnology represented by genetic engineering, cell engineering, and enzyme engineering, breakthroughs have been made in major technologies such as the Human Genome Project, modern biotechnology has been widely used in medical treatment, and the industrialization of biomedicine has accelerated significantly. The pharmaceutical industry has developed rapidly thereupon, and more and more new drugs are constantly coming out. Filtration of raw materials is an important step in biopharmaceutical industrial processes. The good filtration effect achieved by the filtration step can not only greatly reduce the load of the subsequent treatment process, but also effectively improve the quality of the obtained medicine. In the p...
