Abstract

The utility model discloses a seawater suspended substance filtering device which comprises a vacuum pump, a barrel body and a base seat used for supporting the barrel body. A plurality of valves are connected to the top part of the barrel body and are respectively connected with a filtering cup seat, both ends of the barrel body are sealed by end covers, a water discharging valve is arranged at the lower part of an end cover at one end of the barrel body, a vacuum meter is arranged at the upper part of the end cover at one end of the barrel body, and an air exhaust pipe connected with the vacuum pump is arranged at the top part at the other end of the barrel body. The seawater suspended substance filtering device has the advantages that the structure is scientific and reasonable, the filtering device can be directly installed on the filtering cup seats, each filtering cup seat is controlled by a valve, to ensure that each filter can be separately opened or closed; the volume of the barrel body is large, the filtering on a plurality of groups of specimens can be performed by pumping vacuum once, thereby saving time and labor and being quick and highly efficient; the pressure intensity in the barrel body can be mastered through the vacuum meter; whether the fluid is discharged or not can be judged through the transparent end covers. The seawater suspended substance filtering device not only can be used in large, medium or small sized laboratories, but also can be carried to perform field operation.

Description

The water suspension filter

(1) technical field

The utility model relates to a kind of filter, specifically a kind of water suspension filter.

(2) background technology

At present, when carrying out the water suspension filtration in the laboratory, generally adopt triangular flask to filter.When handling a large amount of samples, often a plurality of triangular flasks are linked together with three-way pipe, waste time and energy, hand labor intensity is big, and the slow efficient of the rate of filtration is low.

(3) summary of the invention

The purpose of this utility model is exactly that a kind of water suspension filter is provided in order to address the above problem, and this device rate of filtration is fast, efficient is high, and is easy to use.

The purpose of this utility model is realized by following technical scheme: this water suspension filter comprises the base of vavuum pump, staving, support staving, be connected with a plurality of valves at the top of staving, each valve is connected with the filtration cup, two ends of staving are sealed by end cap, one end end cap bottom of staving is provided with draining valve, its top is provided with vacuum meter, and the blast pipe that is connected with vavuum pump is arranged at the other end top of staving.

Be the volume of liquid behind the observation staving inner filtration directly perceived, the end cap of staving two ends adopts transparent end cap.

The utility model has the advantages that scientific and reasonable for structure, can directly one or more filters be installed in each as required respectively filters on the cup, each filters cup all a valve control, makes each filtration independently to open or close, and adds the flexibility of big filter; The staving volume is big, after taking out vacuum, can filter many groups sample continuously, saves plenty of time and manpower; Vacuum meter is installed is grasped pressure in the staving; Adopt transparent end cap can in time judge whether to want discharge liquid.

(4) description of drawings

Fig. 1 is that water suspension filter master looks schematic diagram;

Fig. 2 is the schematic diagram that Fig. 1 analyses and observe;

Fig. 3 is the enlarged diagram shown in the A among Fig. 2;

(5) specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, this water suspension filter comprises vavuum pump 2, staving 1, supports the base 8 of staving 1, can be connected with the valve 5 more than two or two at the top of staving 1, present embodiment staving 1 top is connected with eight valves 5, and valve 5 adopts ceramic gate valves; Each valve 5 connects filtration cup 4, during filtration, filter 9 is connected on the filtration cup 4, and filter 9 can adopt various filters such as lucite filter, core glass filter and Buchner funnel; Two ends of staving 1 are by

end cap

10,11 sealing, and

end cap

10,11 adopts the lucite transparent materials to make, and can intuitively observe the volume of liquid behind the staving inner filtration; On the one end end cap 10 of staving draining valve 7 and vacuum meter 6 are arranged, the blast pipe 3 that is connected with vavuum pump 2 is arranged at the other end top of staving 1.This installs aesthetic in appearance firm generous, and each parts can adopt light material and universal components such as firm corrosion-resistant PVC, stainless steel, lucite and porcelain valve.Not only can use, go back the work on the spot of portability field operation in the laboratory of large, medium and small type.

During use:

(1) earlier this device base for supporting 8 is positioned over stably on the workbench;

(2) with flexible pipe with

blast pipe

3 and 2 airtight connections of vavuum pump, connect vacuum-pump power supply;

(3) valve-off 5 and stainless steel draining valve 7 are opened vavuum pump, the observation vacuum meter, and the pressure of vacuum in how many definite stavings of filtered sample is closed vavuum pump as required;

(4) again filter 9 is tightened on the filtration cup 4, utilize rubber stopper 12 to seal, in filter 9, pour filtered fluid into then, each valve 5 of manual adjustments, make filtered fluid flow into staving 1 fast, after some several or whole filtrations finish, one or several or whole valve 5 are closed, filter membrane (or filter paper) in dismounting, the replacing filter 9 carries out next sample filtering;

(5) when the vacuum gauge pressure was reduced to zero by force, filtered repeating step (3), (4);

(6) finish or filtered fluid volume when reaching staving volume 2/3rds when sample all filters, open valve 5 and draining valve 7, staving 1 inner filtration liquid is discharged.If need carry out new filtration, repeating step (3), (4) get final product.
