Optionally, the number of the steel supporting transverse bars 1141 is less than that of the transverse bars 111, and the number of the steel supporting longitudinal bars 1142 is less than that of the longitudinal bars 112, so that not each transverse bar 111 is connected with the steel supporting transverse bars 1141, but a part of the transverse bars 111 is connected with the steel supporting transverse bars 1141, and not each longitudinal bar 112 is connected with the steel supporting longitudinal bars 1142, but a part of the longitudinal bars 112 is connected with the steel supporting longitudinal bars 1142.

Optionally, fixing holes are formed in the steel supporting transverse bar 1141, the steel supporting longitudinal bar 1142, the transverse bar 111 and the longitudinal bar 112, so that screws pass through the fixing holes of the steel supporting transverse bar 1141 and the fixing holes of the transverse bar 111, and screws pass through the fixing holes of the steel supporting longitudinal bar 1142 and the fixing holes of the longitudinal bar 112, thereby fixing the steel supporting transverse bar 1141 and the steel supporting longitudinal bar 1142 to the transverse bar 111 and the longitudinal bar 112.

The thickness of the horizontal bars 111, the vertical bars 112 and the circular rings 113 can be reduced by arranging the steel support frames 114 because the filter using the tube plate is subjected to impact force during the back flushing process and needs to bear load. I.e. the thickness of the horizontal bars 111, the vertical bars 112, the circular rings 113, can be optimally adapted according to the structure of the steel support frame 114.

For example: the thickness of the conventional tube sheet is usually 38mm, 28mm, etc., whereas the thickness of the tube sheet in the present application is 18mm, 10mm, etc. Due to the use of the steel support frame 114, the thickness of the plate can be greatly reduced, the material consumption is greatly reduced, the cost of the tube plate is also greatly reduced, and the cost performance of the tube plate is improved.

In addition, the process of cutting the circular tube hole by using the numerical control machine tool is avoided, so that the use of a whole plate and the cutting of the circular plate are avoided, the waste of materials is reduced, and the fault tolerance of the tube plate is improved. In addition, because the transverse strips and the longitudinal strips are crossed to form an installation space for installing the filtering membrane assemblies, the cutting of circular tube holes is avoided, so that the quantity of the assembled filtering membrane assemblies is increased under the condition of the same area, and the membrane assembly rate of the tube plates is increased.

Meanwhile, the utilization rate and the processing cost of materials are not considered, and a required square installation space, a required rectangular installation space or a required right-angled triangle installation space can be formed in the whole plate through cutting.

In addition, the horizontal bars 111, the vertical bars 112 and the circular rings 113 may be made of titanium, steel lining rubber, or composite titanium.
