In the figure: the filter comprises a support 1, a suction bottle 2, a valve 3, a hanging lug 4, a feeding cylinder 5, a pull rod 6, filter paper 7, a filter plate 8, a collecting hopper 9, a sealing ring 10 and a support rod 11.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-4, a polypropylene vacuum suction filter, including support 1, fixedly connected with buchner flask 2 and filter funnel on the support 1, filter funnel is located buchner flask 2's top, and filter funnel's bottom and buchner flask 2's feed inlet sealing fixed connection, filter funnel includes aggregate bin 9 and two feed cylinder 5, two feed cylinder 5 all with the fixed intercommunication in top of aggregate bin 9, install two valves 3 of controlling two feed cylinder 5 and buchner flask 2 intercommunication respectively on the aggregate bin 9, the equal fixedly connected with filter plate 8 in inner wall bottom of two feed cylinder 5, the inside of two feed cylinder 5 all can be dismantled and install filter mechanism.

Adopt above-mentioned scheme, filter plate 8 and feeding section of thick bamboo 5 integrated into one piece, two valves 3 control the feeding state of two feeding section of thick bamboos 5 respectively, cause gas leakage phenomenon when preventing to change filter paper 7.

The filter mechanism comprises an elastic sealing ring 10, the outer side wall of the sealing ring 10 is connected with the inner wall of the feeding cylinder 5 in a sealing and sliding mode, the bottom of the sealing ring is abutted to the filter plate 8, the inner wall of the sealing ring 10 is provided with a mounting groove, and the mounting groove is internally provided with filter paper 7 through screw fixing connection.

Adopt above-mentioned scheme, when needing to change filter paper 7, directly taking out whole filter mechanism from feed cylinder 5, filter paper 7 is changed and is accomplished, perhaps directly takes another new filter mechanism, directly fills in feed cylinder 5 with it for change filter paper 7 convenient and fast, and be difficult for revealing.

The inner wall fixedly connected with bracing piece 11 of a plurality of evenly distributed of sealing ring 10, the common fixedly connected with pull rod 6 of a plurality of bracing pieces 11, pull rod 6 are vertical orientation setting, and the top of pull rod 6 extends to the outside of a feeding section of thick bamboo 5, and the operating filter equipment of being convenient for makes it conveniently take out and install from a feeding section of thick bamboo 5.
