DETAILED DESCRIPTION

[0017] like Figure 1 As shown, the working process of the filter aid device for mud water sample of the utility model is briefly introduced as follows:

[0018] 1. Pour the muddy water sample 400 into the main body 300 with a filter aid device at the bottom;

[0019] 2. The mud water sample 400 is assisted in filtration by the filter aid membrane 100 of the filter aid device;

[0020] 3. Then extract through the extraction membrane 200 of the filter aid device;

[0021] 4. Finally, it enters the collection container from the bottom outlet of the main body 300.

[0022] The muddy water sample 400 is blocked by the filter aid device in the main body 300 to form a water layer 500 and a mud sedimentation layer 600 .

[0023] like Figure 2 As shown, the filter aid membrane 100 is divided into three layers, the upper layer is a 10μm fiber membrane 101, the middle layer is a filter aid layer 102, the filter aid layer 102 is made of PTFE and has a spherical microporous structure, and the lower layer is a 1μm fiber membrane 103; the diameter of the spherical micropores ranges from 1μm to 5μm.

[0024] like Figure 3 As shown, the working principle of the filter aid membrane 100 of the filter aid device for the mud water sample 400 of the present invention is briefly introduced as follows:

[0025] 1. The 10 μm fiber membrane 101 filters large particles A in the muddy water sample 400;

[0026] 2. The microparticles B in the slurry water sample 400 are adsorbed into the micropores of the filter aid layer 102;

[0027] 3. The 1 μm fiber membrane 103 filters small particles C in the muddy water sample 400.

[0028] If the existing filter membrane is used, particles with a diameter of about 1 μm will clog the extraction membrane, so that only 10% of the muddy water sample can pass through the extraction membrane, and then clogged, and the detection test cannot be continued.

[0029] By using the filter aid membrane 100 provided by the present invention, particles with a diameter of about 1 μm can be adsorbed in the filter aid layer 102 , and the filtered water will no longer clog the extraction membrane.

[0030] The above description is only illustrative and not restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all of them will fall within the scope of protection of the present invention.
