[0017] The present invention provides a suction filtration tank for treating wastewater from the production of hexafluoroisopropyl methyl ether. It has the following beneficial effects:

[0018] (1) The present invention uses a cross, a round rod, a heat sink shell, a motor, a horizontal plate, a spring rod, a metal ball, an L-shaped rod and a U-shaped plate in conjunction with a roller. The metal ball is tightly pressed against the bottom of the elastic filter screen and rotates forward. The metal ball rubs under the elastic filter screen to make the elastic filter screen vibrate.

The activated carbon plate increases the contact area with the wastewater, so that the chemical substances in the wastewater are quickly adsorbed by the positively rotating activated carbon plate, thereby preventing the chemical substances in the wastewater from being difficult to be quickly removed and causing poor filtering effect of the equipment. In addition, the inclined plate sweeps the wastewater to the edge of the circular hole plate, allowing the wastewater to quickly enter the circular flat shell for filtration, thereby preventing the wastewater from accumulating in the tank body and causing poor filtering efficiency of the equipment.

[0020] (3) The present invention arranges a wall cleaning device so that the double frame rods, wide plates, short columns, chamfered plates, strip plates and connecting plates cooperate with arc-shaped spring sheets. The chamfer of the chamfered plates scrapes off the scale attached to the wall surface of the tank body, so that the scale generated by the wastewater will not accumulate on the wall surface of the tank body, thereby preventing a large amount of scale on the wall surface of the tank body from causing poor filtering and purification effect of the equipment. In addition, under the elastic force of the arc-shaped spring sheets, the arc-shaped spring sheets slide on the edge of the elastic filter screen, so that a large amount of solid particles of wastewater will not accumulate on the edge of the elastic filter screen, thereby preventing a large amount of solid particles of wastewater from accumulating on the edge of the elastic filter screen and causing the edge of the elastic filter screen to be easily damaged.

During the forward rotation of the rollers 623, the rollers 623 roll on the tank body 2. Under the action of friction, the horizontal plate 615 will not shake violently during the forward rotation, so that the metal ball 617 on the spring rod 616 can rotate stably, so as to avoid the metal ball 617 from shaking violently under the elastic filter screen 6 when the suction tank is filtering hexafluoroisopropyl methyl ether production wastewater, causing the equipment to run unsmoothly.

[0034] When in use, the base 1 supports the tank body 2, the tank body 2 supports the round cover 4, the water pump 5 on the round cover 4 is started, the water pump 5 pumps the hexafluoroisopropyl methyl ether production wastewater into the tank body 2, the elastic filter screen 6 in the tank body 2 filters the hexafluoroisopropyl methyl ether production wastewater, the elastic filter screen 6 filters out the solid particles and floating objects in the hexafluoroisopropyl methyl ether production wastewater, and the filtered wastewater is discharged from the outlet pipe 3 of the tank body 2. Since the solid particles in the wastewater are easily blocked in the mesh seams of the elastic filter screen 6 during the process of the suction tank filtering the hexafluoroisopropyl methyl ether production wastewater, at this time, the tank body 2 supports the heat dissipation shell 613, the motor 614 in the heat dissipation shell 613 is started, the rotating shaft of the motor 614 starts to rotate forward, and the rotating shaft of the motor 614 drives the round rod 612 rotates forward, the round rod 612 rotates forward in the cross 611, the round rod 612 drives the cross plate 615 to rotate forward, the cross plate 615 drives the spring rod 616 to rotate forward, the telescopic end of the spring rod 616 drives the metal ball 617 to rotate forward, and under the elastic force of the spring rod 616, the metal ball 617 is tightly pressed against the bottom of the elastic filter screen 6 to rotate forward during the forward rotation, the metal ball 617 rubs under the elastic filter screen 6 to make the elastic filter screen 6 vibrate, and the elastic filter screen 6 vibrates the solid particles in the mesh gap to prevent the solid particles of wastewater from being blocked in the mesh gap of the elastic filter screen 6 when the equipment is in use, thereby avoiding the problem of poor filtering effect of the equipment caused by the solid particles of wastewater blocking the mesh gap when the suction tank is filtering the hexafluoroisopropyl methyl ether production wastewater.

[0035] While the round rod 612 drives the cross plate 615 to rotate forward, the cross plate 615 drives the L-shaped rod 621 to rotate forward, the L-shaped rod 621 drives the U-shaped plate 622 to rotate forward, and the U-shaped plate 622 drives the roller 623 to rotate forward, so that the roller 623 rolls on the tank body 2 during the forward rotation.

During the positive rotation of the activated carbon plate 76, the activated carbon plate 76 increases the contact area with the wastewater, so that the chemical substances in the wastewater are quickly adsorbed by the positively rotating activated carbon plate 76, so as to avoid the poor filtering effect of the equipment caused by the difficulty in quickly removing the chemical substances in the wastewater when the suction tank is used to filter the hexafluoroisopropyl methyl ether production wastewater.

[0037] The filter device 7 also includes a short plate 77, a thin rod 78 and two inclined plates 79. The short plate 77 is fixed to the bottom of the outer wall of the two L-shaped ring rods 71.

During the forward rotation of the inclined plate 79, the inclined plate 79 sweeps the wastewater to the edge of the circular hole plate 72, allowing the wastewater to quickly enter the round flat shell 73 for filtration, thereby avoiding the accumulation of wastewater in the tank body 2 when the suction tank is filtering the hexafluoroisopropyl methyl ether production wastewater, resulting in poor filtering efficiency of the equipment.

[0038] A wall cleaning device 8 is arranged on the left and right sides of the filter device 7, and the wall cleaning device 8 includes two double-frame rods 81, two wide plates 82, a plurality of short columns 83 and two chamfered plates 84. The two double-frame rods 81 are fixed on the left and right sides of the short plate 77, and the two wide plates 82 are respectively embedded in the inner walls of the two double-frame rods 81, and the two wide plates 82 are respectively located on the side where the two spring rods 616 are away from each other, and a plurality of short columns 83 are respectively fixed on the side where the two wide plates 82 are away from each other, and the two chamfered plates 84 are respectively embedded in one end of the plurality of short columns 83 away from the two wide plates 82, and the chamfers of the two chamfered plates 84 are in rotational contact with the inner wall of the tank body 2.

[0042] While the L-shaped ring rod 71 drives the short plate 77 to rotate forward, the short plate 77 drives the double frame rod 81 to rotate forward, the double frame rod 81 drives the wide plate 82 to rotate forward, the wide plate 82 drives the short column 83 to rotate forward, and the short column 83 drives the chamfered plate 84 to rotate forward, so that during the forward rotation of the chamfered plate 84, the chamfer of the chamfered plate 84 scrapes off the scale attached to the wall of the tank body 2, so that the scale produced by the wastewater will not accumulate on the wall of the tank body 2, preventing a large amount of scale from adhering to the wall of the tank body 2 when the equipment is in use, thereby avoiding the problem of poor filtering and purification effect of the equipment caused by a large amount of scale on the wall of the tank body 2 when the suction tank is filtering hexafluoroisopropyl methyl ether production wastewater.

[0043] While the short plate 77 drives the double frame rod 81 to rotate forward, the double frame rod 81 drives the strip plate 85 to rotate forward, the strip plate 85 drives the connecting plate 86 to rotate forward, and the connecting plate 86 drives the arc-shaped spring piece 87 to rotate forward.
