The upper end that the funnel main part is located the filtrate chamber has the annular to fall the material guide way, and the lower port diameter C of annular to fall the material guide way is less than the upper port diameter D of annular to fall the material guide way, and the annular is fallen the material guide way and is located upper port department and opens there is the opening of falling the material.

The mounting end comprises a holding end and an inserting end, a plurality of anti-slip ribs are uniformly arranged on the outer wall of the holding end along the circumferential direction, and the negative pressure exhaust pipe is arranged on the holding end.

The outer diameter M of the upper end of the inserting end is larger than the outer diameter N of the lower end.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model can utilize the filtrate cavity, the filter disc and the liquid outlet pipe to carry out filtering action, separated liquid can flow out from the liquid outlet pipe, and upper solid separated by the filter disc, such as diatomite, is stopped in the filtrate cavity, and can be poured out conveniently through the annular pouring guide port, and the antiskid rib can ensure that the worker is not easy to slip when in installation;

further, the utility model discloses the material of funnel main part and installation end can be for the PP material, is difficult to damage when using like this, and the cassette then can adopt the PE material to make.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example one

Referring to fig. 1-2, a microporous filter funnel comprises a funnel main body 1 and a mounting end 2, wherein the funnel main body 1 comprises a filtrate cavity 3 and a liquid outlet pipe 4 communicated with the filtrate cavity 3, a filter sheet 3-1 is arranged in the cavity of the filtrate cavity 3, the mounting end 2 is provided with a cavity 5 for the liquid outlet pipe 4 to pass through, and the mounting end 2 is further provided with a negative pressure exhaust pipe 6 communicated with the cavity 5.

Funnel main part 1 is located the lower extreme in filtrate chamber 3 and has male thread section 7, and the upper end chamber wall of cavity 5 has female thread section 8, and through male thread section 7 and female thread section 8's cooperation, 1 screw thread of funnel main part is installed on installation end 2.

Funnel main part 1 is located the upper end in filtrate chamber 3 and has annular pouring guide way 9, and annular pouring guide way 9's lower port diameter C is less than annular pouring guide way 9's last port diameter D, and annular pouring guide way 9 is located the opening of last port department and has fallen material opening 10.

The mounting end 2 comprises a holding end 11 and an inserting end 12, a plurality of anti-slip ribs 13 are uniformly arranged on the outer wall of the holding end 11 along the circumferential direction, and the negative pressure exhaust tube 6 is arranged on the holding end 11.
