Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] figure 1 The structure of the preferred embodiment of the present invention is schematically shown, as shown in it, the preferred embodiment includes a support 1, a sample storage bottle 31, a filtrate collection bottle 71, a plurality of filter membranes 432 (such as figure 2 ) filter disc, filtrate collection device and control system. The bracket 1 mainly has a supporting function and can carry multiple components including the filtrate filtering device. The structure of the bracket 1 in this preferred embodiment is in the shape of "up", and its structural shape can be selected according to the operating space and the configuration of other components, without any special limitation. The sample storage bottle 31 is mainly used to store the sample to be filtered, and it delivers the sample to the filter disc through the sa...

Abstract

The invention discloses an automatic continuous filter, comprising a bracket, a sample storage bottle, a filtrate collecting bottle, a plurality of filtering plates provided with filtering membranes, a filtrate collecting device and a control system, wherein the sample storage bottle can be connected to inlets of the filtering plates in a sealing manner through a sample conveying pipeline; a plurality of filtering plates are detachable and annularly arrayed on the filtrate collecting device, the filtrate collecting device is rotatably arranged on the bracket and is connected to the filtrate collecting bottle through a filtrate conveying pipeline; the control system comprises a valve for controlling the opening and the closing of the sample conveying pipeline, a pressure sensor for detecting the pressure of samples in the sample conveying pipeline, a pipeline drive device for controlling the sample conveying pipeline to be disengaged from and connected, in a sealing manner, with the inlets of the filtering plates, and a controller for controlling the operating time sequences of the valve and the pipeline drive device according to the data of the pressure sensor; and the valve is anelectromagnetic valve arranged on the sample conveying pipeline, and the valve and the pressure sensor are electrically connected to the controller. The automatic continuous filter can realize continuous filtering.

Description

technical field [0001] The invention relates to a filter, in particular to an automatic continuous filter, which belongs to the technical field of sample and mobile phase filtration in chromatographic separation. Background technique [0002] Filters are mainly used for the filtration of samples and mobile phases in chromatographic separation. They can protect chromatographic columns, infusion tube pumps and sampling valves from being polluted by impurities, prevent pipeline clogging, and prolong the service life of chromatographic columns. They are widely used in gravimetric analysis, trace Analysis, colloid separation and sterility experiments. The current filter products include positive pressure filters, negative pressure filters, and syringe filter membrane filters. The positive pressure filter pressurizes the solution to be filtered so that the solution passes through the filter membrane, and the insoluble matter is blocked by the filter membrane to achieve the purpos...
