Referring to fig. 1 to 3, a suction filtration device includes a suction filtration container 1, the suction filtration container 1 is connected to a suction filtration pump 2, and a plurality of suction filtration stations 11 are disposed on the suction filtration container 1. The suction filtration pump 2 adopts the conventional pump body to provide negative pressure inside the suction filtration container 1. The quantity of suction filtration station 11 is 10, and suction filtration station 11 is circular port and interval and evenly sets up. The suction filtration stations 11 are arranged in two rows by taking 5 as a group. The interval between the pumping filtration stations 11 is more than 5cm, so that the subsequent operation is convenient, and the volume of the pumping filtration container 1 is about 10L. The number of suction filtration stations 11 and the volume of the suction filtration containers 1 are not limited to the values disclosed in the present application.

Suction filtration subassembly 3 is installed to suction filtration container 1, and suction filtration subassembly 3 includes a plurality of psammitolite filter heads 31, and in the suction filtration station 11 that corresponds was located in the cooperation of psammitolite filter head 31, suction filtration pipeline 32 is connected to psammitolite filter head 31 below, and suction filtration pipeline 32 is located suction filtration container 1, corresponds on every psammitolite filter head 31 and is equipped with control valve 33, and psammitolite filter head 31 is through grabbing formula structure 4 and filter bowl 34 sealing connection. A filter membrane 35 is arranged between the filter cup 34 and the opening of the sand core filter head 31 in a pressing way. The number of the sand core filter heads 31 is 10, the sand core filter heads are correspondingly arranged on the suction filtration pipeline 32, and the connection mode and the connection structure of the sand core filter heads 31 and the suction filtration pipeline 32 are the same as those of the existing six-connection suction filter. The sand core filter head 31 is simultaneously sealed in the suction filtration station 11 through the sealing ring 43, so that the phenomenon that the sand core filter head 31 and the suction filtration station 11 are gapped to cause abnormal suction filtration is avoided. The shape and size of the filter membrane 35, the bowl 34 and the sand core filter head 31 are conventional. Each sand core filter head 31 is independently arranged through the control valve 33, the sand core filter heads provided with the filter cups 34 can be subjected to suction filtration, the sand core filter heads 31 without the filter cups 34 are closed through the control valves 33 to keep sealing, and one-station or multi-station suction filtration can be realized. Correspondingly installing the filter cups 34 on the sand core filter heads 31, opening the corresponding control valves 33, starting the pumping pump 2, enabling the solution in the filter cups 34 to enter the sand core filter heads 31 through the filter membranes 35, then flowing into the pumping container 1 from the pumping pipeline 32 to realize pumping filtration, wherein the pumping filtration principle is similar to that of the existing multi-joint pumping filtration device.
