Description

Technical Field

[0001] This utility model relates to the field of ceramic membrane technology, and in particular to a plate-type columnar membrane. Background Technology

[0002] Currently, the two ends of columnar ceramic membranes are mainly sealed by a plate structure. The plate structure has square or round holes in the middle to accommodate the filter element and also serve as a permeation water channel. During use, because the plate structure is an integral structure, the mechanical strength of the entire plate is poor, making it easy to break and become unusable. In addition, the manufacturing technology requirements are high. Summary of the Invention

[0003] The purpose of this invention is to provide a plate-type columnar membrane.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A plate-type columnar membrane includes a filter element body, the filter element body being cylindrical, characterized in that mounting plates are provided at both ends of the filter element body along its length direction, a plurality of mounting units are embedded in the mounting plates, the mounting units are arranged in a plurality of rows parallel to the mounting plates radially, the cross-section of the mounting unit is a long rectangular plate, and a plurality of mounting holes are provided through the mounting unit along its length direction, the mounting holes accommodating the filter element body.

[0006] Furthermore, all mounting units in the same row are set flush.

[0007] Furthermore, adjacent mounting units in the same row are installed close together.

[0008] Furthermore, the mounting holes in the mounting unit are arranged in several rows parallel to the radial direction of the mounting plate.

[0009] Furthermore, the mounting holes in adjacent rows are staggered.

[0010] Furthermore, the outer edge of the mounting plate is provided with several annular grooves along the circumferential direction, and the annular grooves are fitted with O-ring seals.

[0011] Furthermore, the mounting unit includes a short mounting unit and a long mounting unit. The short mounting unit has five rows of mounting holes, with eighteen mounting holes in each row. The long mounting unit has five rows of mounting holes, with twenty-six mounting holes in each row.

[0012] Furthermore, the mounting plate has eleven rows of mounting units. The first and eleventh rows of the mounting plate each have a long mounting unit. The second and tenth rows of the mounting plate each have a short mounting unit and a long mounting unit. The third and ninth rows of the mounting plate each have three short mounting units. The fourth to eighth rows of the mounting plate each have two short mounting units symmetrically arranged on both sides and a long mounting unit in the center.

[0013] This invention improves upon the existing integrated ceramic membrane mounting plate by embedding several independent mounting units within the mounting plate. Each mounting unit is further provided with through holes, allowing the filter elements to be tightly arranged within the plate. This ensures the mechanical strength of the plate while maintaining a high filter element packing density and high permeability. Attached Figure Description

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] This utility model discloses a plate-type columnar membrane, such as Figure 1 As shown, a plate-type columnar membrane includes a filter element body 1, which is cylindrical. The filter element body 1 has mounting plates 2 at both ends along its length, and several mounting units 3 are embedded in the mounting plates 2.

[0024] like Figure 2 and Figure 3As shown, there are several rows of mounting units 3 arranged radially parallel to the mounting plate. The cross-section of the mounting unit 3 is a long rectangular plate. All mounting units 3 in the same row are flush and adjacent mounting units 3 in the same row are tightly fitted together.

[0025] The installation unit 3 has several installation holes 4 extending along its length. The installation holes 4 accommodate the filter element body 1 and serve as raw water channels. The installation holes 4 in the installation unit 3 are arranged in several rows parallel to the installation plate radially, and the installation holes 4 in adjacent rows are staggered.

[0026] The outer edge of the mounting plate 2 is provided with several annular grooves 21 along the circumferential direction, such as Figure 4 As shown, preferably, there are two annular grooves 21, and an O-ring is fitted on the outside of the annular grooves 21 to seal the mounting plate 2 to the ceramic membrane filter housing.

[0027] In one embodiment, such as Figure 2 and Figure 3 As shown, the mounting plate 2 has eleven rows of mounting units 3. The first and eleventh rows each have one mounting unit 3, the second and tenth rows each have two mounting units 3, and the remaining rows each have three mounting units 3.

[0028] The mounting unit 3 has two designs: a short mounting unit 31 and a long mounting unit 32. The short mounting unit 31 includes five rows of mounting holes 3, with eighteen mounting holes 3 in each row. The long mounting unit 32 includes five rows of mounting holes 3, with twenty-six mounting holes 3 in each row.

[0029] like Figure 1 As shown, the first and eleventh rows of the mounting plate 2 are provided with a long mounting unit 32, the second and tenth rows of the mounting plate 2 are provided with a short mounting unit 31 and a long mounting unit 32, the third and ninth rows of the mounting plate 2 are provided with three short mounting units 31, and the fourth to eighth rows of the mounting plate 2 are provided with two short mounting units 31 symmetrically arranged on both sides and a long mounting unit 32 in the middle.
