[0019] See also Figures 1 to 4In the embodiment of the utility model, a combined diaphragm frame limiting device comprises two baffles 1 and a combined frame 2, the combined frame 2 is installed between the two baffles 1 and is fixed by bolts 3, a detachable support bar 4 for limiting the anode plate and the cathode plate is installed on the top of the combined frame 2, two upper convex positioning blocks 6 for limiting the support bar 4 are arranged on the top of the baffle 1, a limiting groove is formed between the two upper convex positioning blocks 6, an extended ear 401 of the support bar 4 is located in the limiting groove, the limiting groove is a rectangular groove, when the extended ear 401 is stuck in the limiting groove, a limit is formed, the extended ear 401 limits its rolling and movement in the limiting groove, and keeps the support bar 4 in an upright state, during use of the support bar 4, the weight of the cathode plate is carried on the top, and the anode plate is carried on the structure of the combined frame 2, when the support bar 4 is subjected to force, the support bar 4 will fall flat, causing the support bar 4 to lose its limiting function, so the upper convex positioning blocks 6 are installed on both sides of the support bar 4 to limit the rolling and movement of the support bar 4, so as to keep the support bar 4 upright;

[0020] The structure of the support bar 4 includes a main body, an extended lifting ear 401, a bent portion 402, an anode plate slot 403 and a cathode plate slot 405. Extended lifting ears 401 for lifting and quick release are arranged on both sides of the main body. The main body is provided with bent portions 402 distributed at equal distances. Anode plate slots 403 for limiting the anode plate are arranged on the inner side of the bent portion 402. A cathode plate slot 405 for limiting the cathode plate is opened on the top of the main body and is located between two adjacent bent portions 402. The cathode plate slots 405 and the bent portion 402 opened by the support bar 4 make it serrated. The support bar is installed on the upper edge of one side of the combined frame 2, and the cathode plates in the cathode area are limited to the same straight line, so that the cathode plate in the combined diaphragm frame and the two adjacent plates of the anode plate are aligned in the center. The anode plate is inserted into the inside of the anode plate slot 403, supported on the combined frame 2, and supported by the combined frame 2, so as to achieve the fixed distance positioning function of the anode plate and the cathode plate.

[0021] In a preferred embodiment, a positioning groove 5 is provided at the top of the combined frame 2, and a downward protruding positioning block 404 located inside the positioning groove 5 is provided at the bottom of the support bar 4. When the anode plate is placed, it slides down along the anode plate slot 403 and is supported in the positioning groove 5. The downward protruding positioning block 404 serves to connect with the combined frame 2. The downward protruding positioning block 404 can move up and down in the positioning groove 5. The length of the support bar 4 is the same as the overall length of the diaphragm frame. Therefore, the support bar 4 is prone to bend when under pressure and detaches from the top of the combined frame 2. After the positioning groove 5 and the downward protruding positioning block 404 are added, deformation of the support bar 4 can be effectively avoided.

[0022] In a preferred embodiment, the support bar 4 is an RPP board, and the limiting cathode plate is supported in the cathode board slot 405 of the support bar 4. The RPP material has a low heat deformation temperature, low transparency, low gloss, and low rigidity, but has stronger impact strength. The impact strength of RPP increases with the increase of ethylene content, and the Vicat softening temperature is 150 degrees, which is suitable for this application.

[0023] In a preferred embodiment, the RPP plate of the support bar 4 has a built-in metal steel bar and the RPP plate is wrapped on the outside, which has the rigidity to bear the weight of a whole row of cathode plates. The metal steel bar can improve the performance of the support bar 4 so that it has a better load-bearing capacity, and after loading the rigid metal steel bar, the cathode plates inside the diaphragm frame can be taken out at one time by lifting the extended lifting ears 401 on both sides, thereby improving the efficiency of taking out the cathode plates.

[0024] It should be noted that the above embodiments all belong to the same utility model concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference can be made to the description in other embodiments.

[0025] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
