Description

Plate-shaped microporous ceramic structure with ribs

technical field

The invention relates to the technical field of water purification equipment, in particular to a plate-like microporous ceramic structure with ribs.

Background technique

As a microporous ceramic used in liquid filtration equipment, it has many advantages, such as low cost, easy to clean after clogging, basically all the flow is restored after cleaning, the filtration accuracy does not decrease, and the quality of the liquid can be kept stable from the beginning to the end of the filtration process. Wait, so it's already widely used.

Microporous ceramics are generally made into plates, tubes or hemispheres. When filtering, the liquid enters from one side and flows out from the other side. The particles and suspended solids in the liquid are trapped on the surface of the side where the liquid enters, and deposit or accumulate on the surface to form a filter cake. As the filtration process progresses, the thickness of the filter cake will become thicker and the filtration resistance will increase. Although the quality of the liquid will not decrease, the flow of the liquid will become smaller and smaller, which will eventually lead to a flow that cannot meet the requirements. At this time It is necessary to clean the microporous ceramics to remove the intercepted substances on the surface of the microporous ceramics and restore the filtration flow. People generally hope that the larger the amount of liquid filtered from the beginning of filtration to cleaning, the better. In other words, if the filtration flow rate is constant, the longer the normal filtration time, the better. This actually reflects the dirt-holding capacity of microporous ceramics. The greater the dirt-holding capacity, the longer the interval between two cleanings, and the greater the amount of liquid filtered in a given filtration cycle. The capacity is directly proportional to the filter area, that is, the larger the filter area, the greater the dirt-holding capacity.

For tubular microporous ceramics, one method is to increase the filtration area by increasing the number of microporous ceramic tubes, which has a complex structure and high cost; another method is to increase the filtration area by increasing the diameter of the microporous ceramic tubes , The space in the microporous ceramic tube is just wasted in vain like this, and equipment will become very huge. Apparently, these two kinds of methods all make the equipment cost rise obviously.

For plate-shaped microporous ceramics, a method is to directly increase the area of the plate (such as increasing the diameter of the disc-shaped microporous ceramics). It is easy to be damaged during installation and use. On the other hand, a large size means a large volume of the equipment. Therefore, the method of directly increasing the area of the microporous ceramic plate will increase the manufacturing cost of the equipment rapidly. Another method is to stick two circular plate-shaped microporous ceramics together through a connecting partition, the upper and lower surfaces of the outer circumference of the connecting partition are respectively sealed and connected with the circular microporous ceramics, and the middle of the connecting partition is set There is a connecting pipe passing through the center of one of the ceramic sheets, and the connecting pipe is hermetically connected to the ceramic sheet, as the Chinese patent "Microporous ceramic filter element for water purifier" (patent application number 200520000553.3) discloses such a microporous ceramic filter element structure . The size of this structure is relatively compact, and the filtration area can be increased under the premise of a small increase in volume. However, the structure of this ceramic component is relatively complicated, the reliability is reduced, and the production cost is high.

Contents of the invention

The technical problem to be solved by the present invention is to provide a plate-shaped microporous ceramic structure with ribs for liquid filtration equipment in view of the above-mentioned deficiencies in the prior art. The main function of the present invention is to ensure that the filtration accuracy is not reduced, and On the premise of a small increase in the volume of the microporous ceramics, the filtration area is significantly increased, so that the filtration device of the present invention can have a smaller device volume and a lower manufacturing cost under the same filtration flow rate and filtration accuracy.

Another technical problem to be solved by the present invention is to provide a special water purifier for drinking fountains comprising the plate-like microporous ceramic structure with ribs.

The technical scheme adopted by the present invention to solve the above-mentioned technical problems is: extending ribs in the thickness direction of the plate-shaped microporous ceramics, and providing a liquid flow channel in the ribs.

The plate-shaped microporous ceramics can have a filter surface of one side or two sides; its peripheral shape can be circular, oval, or polygonal; its plate shape can be flat , can be arc plate shape, also can be spherical plate shape.

For plate-shaped microporous ceramics with a single-sided filter surface, one side is the liquid inlet surface and the other side is the liquid outlet surface, and the ribs are arranged on one side of the liquid inlet surface and on one side of the liquid outlet surface. A connector is provided on the side. The size of the periphery of the connector is such that after the plate-shaped microporous ceramics are placed on it, the periphery of the plate-shaped microporous ceramics is completely placed in the periphery of the connector, and the center of the connector is provided with a liquid outlet pipe. The connecting piece and the plate-shaped microporous ceramics are sealed and connected at the periphery, and a liquid flow channel is arranged between the two in the direction of the plate surface. on file. The shape of the liquid flow channel can be radial, mesh or planar. When filtering, the liquid enters the microporous ceramic from all surfaces of the liquid inlet side of the microporous ceramic, and the particles and suspended matter in the liquid are trapped on the surface of the microporous ceramic, thereby separating the particles and suspended matter in the liquid from the liquid. The liquid entering the microporous ceramics will flow to the liquid flow channel, and the liquid in the liquid flow channel in the convex rib will flow to the liquid flow channel arranged in the direction of the plate surface, and all the liquid will finally flow to the liquid outlet pipe and flow out from the liquid outlet pipe.

For plate-shaped microporous ceramics with double-sided filtering surfaces, both sides are liquid inlet surfaces, and a liquid flow channel is provided in the direction of the plate surface in the middle of the plate-shaped microporous ceramics, which can be evenly spaced on the two liquid inlet surfaces. The ribs are set, and the ribs can also be set on one of the liquid inlet surfaces. In addition, a central hole is set in the center of the plate-like microporous ceramics, and the central hole communicates with the liquid flow channel arranged in the direction of the plate surface. The liquid flow channel arranged in the direction of the plate surface communicates with the liquid flow channel in the rib. When filtering, the liquid enters the microporous ceramic from each surface of the two liquid inlet sides of the microporous ceramic, and the particles and suspended matter in the liquid are trapped on the surface of the microporous ceramic, thereby separating the particles and suspended matter in the liquid from the liquid . The liquid entering the microporous ceramics will flow to the liquid flow channel, the liquid in the liquid flow channel in the convex rib will flow to the liquid flow channel arranged in the direction of the plate surface, and all the liquid will finally flow to the central hole.

The ribs can be circular or strip-shaped; the circular can be circular, quadrangular or polygonal; the strip can be straight or arc-shaped; The bar described above can also be a very short bar, which becomes a column.

The beneficial effects of the present invention are: under the premise that the volume of the microporous ceramics increases significantly, the filtration area is significantly increased, and the filtration accuracy of the microporous ceramics can be maintained without decreasing, so that the filter device of the present invention can achieve the same filtration flow rate and filtration accuracy Under conditions, the volume of the equipment is small and the manufacturing cost is low.
