Description

Portable filter

Technical Field

The utility model relates to a filtration equipment especially relates to a portable filter.

Background

The filter that present laboratory adopted is buchner funnel (filter paper) and glass psammitolite filter, all needs to connect the vacuum suction pump, can not carry the on-the-spot sample, can not select to change the filter screen of different mesh numbers according to the demand for the application range of filter is narrower, is unfavorable for using widely. In addition, the existing filter can not measure the volume of the sample, and waste of the detected sample is easily caused.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a need not portable filter of vacuum suction pump.

The technical scheme is as follows: the utility model relates to a portable filter, which comprises a cylinder body and a piston component, wherein a feed inlet is arranged at the outer side of the cylinder body, a discharge outlet is arranged at the top of the cylinder body, and a filter layer is arranged in the inner cavity of the cylinder body; the piston assembly comprises a push plate, a piston rod and a piston pressing sheet, and the piston pressing sheet is fixedly connected with the stirrer.

Preferably, the blades of the stirrer are rotating blades. In the propelling process, the stirrer rotates and stirs, so that the high-concentration sample is more fully mixed, and the blockage of the filter screen is reduced, and the filtering effect is influenced.

Preferably, the filter layer is the multilayer filter screen that the interval set up, and first layer filter screen passes through horizontal rotary mechanism detachably to be installed between the feed inlet of barrel inner chamber and discharge gate, and the filter screen edge covers there is the sealing washer. First layer filter screen suction filtration in-process can be dismantled out and wash, has solved thick liquids and has blockked up the filter screen problem, and other filter screens can select the specification as required, accurate filtration.

Preferably, the second filter screen of the filter layer is arranged in the cavity between the feeding hole of the cylinder body and the piston pressing sheet.

Preferably, a visual window with scales is arranged on the side surface of the cylinder body.

Preferably, the bottom of the push plate is provided with an anti-slip layer. Avoid the phenomenon of skidding appearing when promoting the push pedal.

Has the advantages that: compared with the prior art, the utility model, have following advantage: 1. by arranging the piston assembly, a vacuum suction pump is omitted, and the device is easy to carry, sample on site and convenient to operate; 2. the stirrer rotates and stirs to reduce the blockage of the filter screen; 3. the first layer of filter screen passes through horizontal rotary mechanism demountable installation, satisfies different filtering requirements, improves application scope.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

The utility model relates to a portable filter, which comprises a cylinder body 1 and a piston component 2, wherein a feed inlet 3 is arranged at the outer side of the cylinder body 1, a discharge outlet 4 is arranged at the top of the cylinder body 1, and a filter layer 5 is arranged in the inner cavity of the cylinder body 1 of the filter; the piston assembly 2 comprises a push plate 21, a piston rod 22 and a piston pressing sheet 23, and a stirrer 24 is fixedly connected to the piston pressing sheet 23.

Filter layer 5 is 2 layers of filter screens that the interval set up, and first layer filter screen 51 is installed between the feed inlet and the discharge gate of filter through rotatory silk spare 6 detachably, and the filter screen edge covers has the sealing washer, and 2 nd layer filter screen 52 second filter screen is located in the cavity between barrel feed inlet and the piston preforming, for user's required correct grinding filter screen specification. The stirrer 24 is positioned in a cavity formed by the first layer of the filter screen 51 and the 2 nd layer of the filter screen 52, and the blades of the stirrer 24 are 360-degree rotating blades.

The left side surface of the cylinder body is provided with a visual window 7 with scales, the feeding port 3 is provided with a feeding hopper, and a valve is arranged on a conveying pipe of the feeding hopper. The bottom of the push plate 21 is provided with an anti-slip layer, and the lower end of the anti-slip layer is carved with a plurality of anti-slip lines.

During the filtration, at first will wait to filter the sample and get into the conveyer pipe through the feeder hopper inside, open the valve on the conveyer pipe this moment, in the sample entering barrel 1 in the conveyer pipe, visual window 7 is observed this moment, when reacing preset volume, closes the valve. The staff upwards promotes push pedal 21, and push pedal 21 drives piston preforming 23 upward movement through piston rod 22, promotes the sample upward movement, and the filtration sample passes through filtration layer 5 and finally discharges through filtrating outlet pipe 7. When the filter screen 51 needs to be replaced, the rotary wire element 6 can be unscrewed to replace the filter screen.
