Although the silicon carbide membrane filtration device currently used can meet normal use needs, it still has the following problems in actual use:

[0004] 1. Most of the existing silicon carbide filtration membrane groups are tubular filters, which have poor filtration effects in the filtration treatment of distillation residues or wastewater.

[0005] 2. In the use of existing silicon carbide flat membrane groups, several groups of frames are usually included, and multiple silicon carbide flat membranes are arranged inside the frames. However, in the installation and use of the frames, two main frames and a side panel need to be installed, and then multiple silicon carbide flat membranes are installed in sequence, and finally another side panel is installed. The side panel and the main frame are still installed by bolts, which is not only troublesome to install, but also very time-consuming and labor-intensive for the installation of multiple groups of frames. Specific tools are also required to operate, which greatly affects production efficiency. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Depend on Figures 1 to 6The invention provides a method for providing a plurality of frames 10 arranged vertically, wherein a plurality of silicon carbide diaphragms 20 are clamped in the frames 10 at equal intervals, wherein the frames 10 include two symmetrically distributed main frames 11, wherein a waist-shaped block 111 is provided on the top of the main frames 11 for clamping the plurality of frames 10 vertically, wherein a water channel 112 is provided in the main frames 11 along the long side direction, wherein a water tank connected to the water channel 112 is provided in the waist-shaped block 111, wherein two symmetrically distributed side panels 12 are provided between the main frames 11, wherein a water tank connected to the water channel 112 is fixed on the side panels 12. The side plate 12 is provided with a plurality of water holes matching the silicon carbide diaphragm 20, and a water collecting plate 13 is fixed on the top of the main frame 11. Through the arrangement of the frame 10, the silicon carbide diaphragm 20 and the water collecting plate 13, when the distillation residue or waste water is treated, the flat silicon carbide diaphragm 20 is used to filter it, and the organic and inorganic substances in the waste water are separated. Compared with the tubular silicon carbide diaphragm 20, the filtering and separation effect is better. In the use of the above-mentioned equipment, it belongs to the prior art and will not be described in detail here.

[0028] Considering the problem of inconvenience in installation of the existing silicon carbide flat membrane group during use, notches are provided at both corners of the side plate 12, the notches are located below the latch 121, a connecting cylinder 122 is fixed in the notches, both ends of the main frame 11 are fixed with a fixing cylinder 113 coaxial with the connecting cylinder 122, when the side plate 12 is installed, the connecting cylinder 122 is clamped with the fixing cylinder 113, a plurality of through holes are provided on the fixing cylinder 113, a rotating shaft 30 is coaxially provided inside the fixing cylinder 113, two symmetrically distributed limit blocks 31 are coaxially rotatably connected to the rotating shaft 30, and a coaxially provided rotating shaft 30 is provided There is a cam 32, which is located between the two limit blocks 31. A connecting groove is provided on the rotating shaft 30. A connecting block is fixed at the connection between the cam 32 and the rotating shaft 30. The connecting block is engaged with the connecting groove. The two limit blocks 31 are slidably connected with the same movable plate 33. In this embodiment, sliding rods are fixed at the four corners of the bottom of the movable plate 33. A sliding hole matching the sliding rod is provided on the limit block 31. The sliding rod slides coaxially inside the sliding hole. A plurality of card blocks 34 are connected to the top of the movable plate 33 through a spring. The cross section of the card block 34 is a right-angle trapezoid. The plurality of card blocks 34 are respectively connected to the corresponding through holes. The connecting tube 122 is provided with a plurality of slots 1221 matching with the block 34. When the block 34 is completely located in the slot 1221, the right angle side of the block 34 reaches a limit with the right angle side of the slot 1221. The fixed tube 113 is provided with a limit slot 1131. The bottoms of the two limit blocks 31 are respectively fixed with limit plates 311 matching with the limit slot 1131. Through the arrangement of the fixed tube 113, the connecting tube 122 and the block 34, when installing between the side plate 12 and the main frame 11, it is only necessary to align the connecting tube 122 with the fixed tube 113 and push it forward. As the fixed cylinder 113 moves coaxially, the block 34 shrinks into the through hole under the action of external force. When the connecting cylinder 122 moves to the end of the fixed cylinder 113, all the blocks 34 and the slots 1221 in the connecting cylinder 122 are limited, thereby achieving the effect of quick installation of the side plate 12, and the installation can be achieved without using tools. When the side plate 12 needs to be disassembled, the rotating shaft 30 is rotated counterclockwise, and the cam 32 rotates under the drive of the rotating shaft 30, and the movable plate 33 falls off downward under the action of gravity. At this time, the block 34 and the slot 1221 are released from the limit, achieving the effect of quick disassembly;

[0029] At the same time, considering that the locking components inside the connecting tube 122 have a limited service life or sudden structural damage, in order to facilitate its replacement, when the block 34 contacts the slot 1221 to limit the position, the rotating shaft 30 can be directly driven out of the fixed tube 113, which is very convenient for disassembly, and the installation methods of the upper limit block 31 and the cam 32 on the rotating shaft 30 are simple and effective.

[0030] refer to Figure 7 As shown, in order to limit the rotation angle of the cam 32 and prevent the cam 32 from rotating too much, which is not conducive to cooperation with the movable plate 33, an arc groove 321 is provided on the cam 32, and the arc groove 321 is a quarter arc groove. A connecting rod 312 that passes through the arc groove 321 is fixed on one side of one of the limit blocks 31, and a polygonal mounting groove is provided on the other limit block 31. A polygonal clamping block 313 located inside the polygonal mounting groove is fixed on one end of the connecting rod 312. Through the settings of the arc groove 321, the polygonal clamping block 313 and the polygonal mounting groove, when the rotating shaft 30 is rotated, the arc groove 321 is limited so that the maximum rotation angle of the cam 32 is 90 degrees, thereby avoiding the problem of the cam 32 rotating too much and being out of control.

[0031] refer to Figure 7 As shown, in order to prevent the cam 32 from rotating when holding the movable plate 33, an elastic card 40 is provided in the arc groove 321. The cam 32 and the elastic card 40 are both made of stainless steel. Through the provision of the elastic card 40, the cam 32 will not deflect when subjected to external vibrations. When manually rotating the shaft 30 to drive the cam 32, only a large force needs to be applied.

[0032] refer to Figure 8 As shown, in order to prevent the block 34 from deviating from the movable plate 33 and thus affecting the assembly of the block 34 and the through hole, a pin shaft 341 penetrating the movable plate 33 is fixed to the bottom of the plurality of blocks 34 .

[0033] refer to Figure 8 As shown, a contact plate 302 located inside the fixed cylinder 113 is fixed at one end of the rotating shaft 30 , and the contact plate 302 contacts the innermost side of the fixed cylinder 113 . A handle 301 is fixed at the other end of the rotating shaft 30 to facilitate control of the rotating shaft 30 .

[0034] When the utility model is used:

[0035] First, when installing the frame 10, align the connecting tube 122 with the fixing tube 113 and push it forward. As the connecting tube 122 moves coaxially with the fixing tube 113, the block 34 contracts into the through hole under the action of external force. When the connecting tube 122 moves to the end of the fixing tube 113, all the blocks 34 and the slots 1221 in the connecting tube 122 are limited.

[0036] Then, when the side panel 12 needs to be disassembled, the rotating shaft 30 is rotated counterclockwise, the cam 32 is rotated under the drive of the rotating shaft 30, and the movable plate 33 falls off downward under the action of gravity. At this time, the clamping block 34 and the clamping slot 1221 are released from the limit, and the side panel 12 can be pulled out to one side;

[0037] Finally, when the locking component inside the fixed tube 113 is replaced or repaired, after the clamping block 34 contacts and limits the clamping groove 1221 , the rotating shaft 30 can be directly driven to separate from the fixed tube 113 .

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
