Description

Heparin sodium purification device Technical Field The invention relates to the technical field of heparin sodium purification equipment, in particular to a heparin sodium purification device. Background Heparin sodium is a natural anticoagulant substance extracted from intestinal mucosa or lung of animals such as pigs, cattle and the like, and is widely applied to the fields of thromboembolic disease prevention and treatment, cardiovascular surgery, hemodialysis and the like. At present, in the industrial purification process of heparin sodium, a ceramic membrane filtration technology is often adopted for separation. Ceramic filter elements are widely used as filter media because of their high temperature resistance, acid and alkali resistance, high mechanical strength, long service life and the like. Existing ceramic membrane filtration devices typically include a closed tank and a hollow ceramic filter element fixedly mounted within the tank. During operation, heparin sodium enzymolysis liquid enters the tank body through the liquid inlet pipe, heparin sodium molecules and small molecular impurities penetrate through the porous ceramic wall to enter the filtering flow passage inside the filter element under the driving of pressure to form purified liquid and discharge, and macromolecular proteins and other impurities are trapped on the outer wall of the filter element or blocked in ceramic micropores. The existing heparin sodium ceramic membrane filtration and purification equipment has the defect that the membrane flux is rapidly reduced because macromolecular substances such as protein, mucopolysaccharide and the like contained in heparin sodium enzymolysis liquid are easily adsorbed and deposited on the inner surface and the outer surface of a ceramic filter element and in a micro-channel. The traditional back flushing mode can only be used for introducing clear water or cleaning liquid from one end of the filter element, so that intractable pollutants attached to the inner wall are difficult to effectively remove, the pollutants in the surface area of the filter element can not be thoroughly cleaned, the filtration efficiency is reduced, and the filtration efficiency of the purification equipment is affected. Disclosure of Invention Therefore, the invention aims to provide a heparin sodium purifying device, which aims to solve the problems that the conventional back flushing mode can only introduce clear water or cleaning liquid from one end of a filter element, and is difficult to effectively remove stubborn pollutants attached to the inner wall, and the pollutants in the surface area of the heparin sodium purifying device cannot be thoroughly cleaned, so that the filtering efficiency is reduced. Based on the above object, the present invention provides a heparin sodium purifying device, comprising: The purifying tank is internally provided with a first installation cavity, a purifying cavity and a second installation cavity which are mutually isolated in sequence along the axial direction, and the outer wall of the purifying tank is provided with a liquid inlet pipe communicated with the purifying cavity; the ceramic filter element is arranged in the purification cavity in a rotating manner and is provided with a filtering flow passage which is axially arranged, and one end of the filtering flow passage penetrates through the first installation cavity and extends out of the purification tank; The driven toothed ring is arranged in the first mounting cavity and is fixedly connected with the ceramic filter element; The driving mechanism is fixedly connected with the purification tank and provided with a driving gear extending into the first mounting cavity, and the driving gear is in driving connection with the driven toothed ring and is used for driving the ceramic filter element to rotate; The cleaning mechanism is provided with a cleaning shell fixedly arranged in the second installation cavity, a composite flow channel is axially arranged in the cleaning shell, the other end of the filtering flow channel, which faces to the second installation cavity, can be in disconnectable communication with one end of the composite flow channel, the other end of the composite flow channel extends out of the purification tank, a cleaning roller is in sliding connection with the composite flow channel, and the other end of the composite flow channel is used for providing guiding-out of cleaning media and purification liquid.
