Abstract

The invention relates to an ultrafiltration membrane stirring and filtering device which structurally comprises a filtering case body, a pressurizing device and an ultrafiltration membrane; the pressurizing device and the ultrafiltration membrane are arranged in the filtering case body; a liquid outlet is formed in the lower part of the filtering case body; the filtering case body is connected with a stirring case body through a connecting pipe; an infusion pump is arranged on the connecting pipe; a star type stirrer is arranged in the stirring case body; a feed opening is formed in the stirring case body. The ultrafiltration membrane stirring and filtering device has the capability of regulating the flow rate and protecting the ultrafiltration membrane, can purify a solution repeatedly to improve the concentration and the purity of the solution, has good leak tightness, prevents material from volatilizing, reduces the cost, avoids pollution to the ambient environment and harm to people, and has an excellent self-protection function.

Description

technical field [0001] The invention relates to a chemical machinery, in particular to an ultrafiltration membrane stirring and filtering device. technical background [0002] The industrial application of ultrafiltration membrane equipment is very extensive, and it has become one of the new chemical unit operations. It is used in separation, concentration and purification of biological products, pharmaceutical products and food industry; it is also used in terminal treatment devices in blood treatment, wastewater treatment and ultrapure water preparation. In my country, ultrafiltration membrane equipment has been successfully used to concentrate and purify Chinese herbal medicine. With the advancement of technology, the screening function of ultrafiltration membrane equipment will be improved and strengthened, and its contribution to human society will also increase. The structure of ultrafiltration membrane is divided into symmetrical and asymmetrical. The former is iso...
