Embodiment Construction

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

[0018] figure 1 The structure of the preferred embodiment of the present invention is schematically shown. As shown, the preferred embodiment includes a holder 1, a sample storage bottle 31, a filtrate collection bottle 71, and 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 a filtrate filter device. The structure of the bracket 1 of the preferred embodiment is in the shape of "upper", and its structure shape can be selected according to the operating space and the configuration of other components, and is not particularly limited. The sample storage bottle 31 is mainly used to store the sample to be filtered, and the sample is transported to the filter tray through the sample transport pipe 3...

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 an electromagnetic 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, belonging to the technical field of sample and mobile phase filtration in chromatographic separation. Background technique [0002] The filter is mainly used for the filtration of samples and mobile phase in chromatographic separation. It can protect the chromatographic column, infusion pipe pump and injection valve from contamination by impurities, prevent pipeline blockage, and extend the service life of the chromatographic column. It is widely used in gravimetric analysis and micro Analysis, colloid separation and sterile 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 purpose of sep...
