[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-2The utility model provides a support structure for a filter screen plate, comprising: an equipment cylinder 1, a support ring 2 connected to the equipment cylinder, four filter element skeletons 3 covered on the support ring, and a support beam 4 arranged below the connection between adjacent filter element skeletons, wherein the support ring is welded to the equipment cylinder through a plurality of first welding members 5, and the four filter element skeletons are respectively welded to the support ring through second welding members 6, the support beam is an "I"-shaped structure, the second welding member is arranged at the top of the support beam, the first welding members are evenly distributed circumferentially along the center of the support ring as the center point, the two ends of the first welding member are respectively fully welded to the support ring and the equipment cylinder, the first welding member and the second welding member are welding studs, the filter element skeleton is fully welded to the second welding member, and the welding structure is relatively firm.

[0021] See also Figure 3-4 The filter element skeletons on both sides are connected to the equipment cylinder through a sealing assembly. The sealing assembly includes a pressure plate 7 covered on the filter element skeletons on both sides. The pressure plate is detachably connected to the support ring through a fixing bolt 8. A sealing medium 9 is filled between the filter element skeleton and the inner side wall of the equipment cylinder. The sealing medium is a ceramic fiber rope stacked side by side. The filter element skeletons on both sides may expand at high temperatures. The ceramic fiber rope has a certain compression rate, thereby ensuring the elastic connection and sealing between the filter element skeletons on both sides and the equipment cylinder.

[0022] Specifically, the filter element skeleton adopts Johnson mesh as the filter element and is made into a sieve plate shape. The mesh holes of the Johnson mesh are constituted as medium lead-out holes. The Johnson mesh has high strength and strong permeability, which can make the filter element have automatic backwashing function. During normal operation, water flows from the inside to the outside through the filter element, and during backwashing, water flows from the outside to the inside. After the backwashing is completed, the filter element performance can be restored to the initial state, so that its life span and the equipment life span remain the same, thereby reducing the operating cost of the equipment.

[0023] Specifically, a reinforcing rib plate 10 is provided between the bottom of the support ring and the inner wall of the equipment cylinder to make the structure more stable.
