Detailed Description

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

As shown in fig. 1, the utility model provides a positive pressure filtration system is used in laboratory, filter disc 1 including the tube-shape, filter disc 1's top is equipped with sealed lid 2, and the bottom is equipped with filter 3, sealed lid 2 goes up to alternate has feed hopper 4 and intake pipe 5, be equipped with valve 41 on the feed hopper 4, intake pipe 5 links to each other with the pneumatics equipment, be equipped with through-hole 31 and filter disc 1 intercommunication on the filter 3, filter paper 7 has been laid to through-hole 31 top, and the below is connected with filtrate pipe 8.

The utility model discloses a use is: firstly, a certain amount of slurry to be filtered is fed into the filter disc 1 through the feeding funnel, then the valve 41 on the feeding funnel 4 is closed, finally the air compression device is started, as the air pressure in the filter disc 1 is increased, the moisture in the slurry penetrates through the filter paper 7 under the action of pressure and is discharged from the filtrate pipe 8, and the remaining solid materials are compressed into filter cakes. Compare traditional vacuum disc filter, the malleation filtration mode that this application adopted is structurally simpler, uses also convenient and fast more, need not water ring vacuum pump, deareator, does not also consume the running water, has saved equipment cost and use cost greatly.

In order to take out the filtered cake and replace the filter paper, it is possible to design the sealing cover 2 in an openable manner, but there is a certain disadvantage in convenience of use and a specific pressing structure is required to fix the filter paper 7. Therefore, it is preferred that the filter disc 1 is connected to the filter plates 3 by means of a press handle 9, and that the bottom of the filter disc 1 is provided with a sealing gasket 11. The pressing handle 9 is similar to a locking handle used on a window, the sealing washer 11 is compressed and deformed under the action of the pressing handle 9, so that the filter disc 1 is sealed with the filter plate 3, and the filter paper 7 is laid on the filter plate 3 and pressed on the filter plate 3 through the filter disc 1. The structure can be convenient for taking down the filter plate 3 and removing filter residues, and can also be convenient for replacing and compressing and fixing the filter paper 7.

The filter plate 3 is provided with a concave tapered groove 32, the opening size of the top of the tapered groove 32 is the same as the inner diameter of the filter disc 1, and the through hole 31 is arranged at the bottom of the tapered groove 32. The conical groove 32 can increase the filtering area, improve the filtering effect and facilitate the collection of the filtrate.

The air pressure provided by the air pressure device needs to be controlled during filtering so as not to damage the device. The air compression device can be directly set to stably provide a specific pressure. Further, an exhaust pipe 6 is inserted into the sealing cover 2, and a pressure release valve 61 is arranged on the exhaust pipe 6. The pressure relief pressure of the pressure relief valve 61 is set in advance, and when the gas pressure in the filter disc 1 reaches a certain value, the gas can be discharged from the pressure relief valve 61, so that the device is protected. A pressure gauge 62 may be provided on the vent tube 6 to provide a visual indication of the pressure within the filter disc 1 during the filtration process.

The utility model discloses utilize the high-pressure gas that air compression equipment provided as power, promote the thick liquids in the filter disc and pass the filter paper on the filter, realize liquid filtration, whole device simple structure, convenient to use is swift, need not water ring vacuum pump, deareator, also consumes the running water, has saved equipment cost and use cost greatly, has fine practicality and application prospect.
