Description

Technical Field

[0001] The invention relates to an industrial water filter, in particular to an industrial water filtering device. Background Art

[0002] In industrial production, both the incoming water to the equipment and the wastewater discharged from the equipment need to be filtered, especially the wastewater discharged from the equipment. Some large particles of waste can be removed by sedimentation, and the small density waste that is easy to float can be removed by filter salvage, filtration and other means. However, it is more troublesome to remove some floating and suspended small-sized particles, filaments, and flocs, because the gears are smaller than the filter holes of the filter and are difficult to filter out. The more effective means in the prior art is to add flocculants to precipitate these wastes and pollutants for removal. This method will affect the different amounts of flocculants added due to the different waste content in the water. This requires measurement and proportioning before treatment.

Sewage is drawn from the sedimentation tank 1 into the filter cartridge 3 through the secondary water pipe 21 for filtration.

[0040] In this embodiment, a bracket 31 is provided at the bottom of the filter cartridge 1 3 , and the bracket 31 is used to support the filter cartridge 1 3 and the filter cartridge 2 4 .

[0041] In this embodiment, an overflow cover 41 is provided on the top of the filter cartridge 2 4 to prevent sewage from overflowing through the hole on the top of the filter cartridge 2 4 .

[0042] In this embodiment, a connecting head 51 is provided at the top of the connecting tube 5, and the connecting head 51 is connected to the connecting tube 5 via a connecting block. A motor can be provided on the top of the connecting head 51 to drive the connecting tube 5 to rotate. While rotating, the inner sleeve 73 stuck on the connecting tube 5 will be driven to rotate through the key on the tube wall, so that the adsorption rod 71 can rotate.

[0043] In this embodiment, the adsorption structure 7 includes an adsorption rod 71, an outer sleeve 72 and an inner sleeve 73. The adsorption rod 71 is provided with a plurality of rods 71 ​​and is arranged at equal intervals on the outside of the cylindrical outer sleeve 72.

[0044] In this embodiment, the adsorption rod 71 includes a parallel rod 711 and an arc rod 712. The arc rod 711 is fixedly connected to the bottom of the parallel rod 711. A suction hole 713 is provided at the bottom of the arc rod 712. Bristles 714 are provided at the edge of the suction hole 713.

[0045] In this embodiment, the bubble manufacturing structure 8 includes an annular tube 81, a main air pipe 82 and a branch air pipe 83.

One end of the main air pipe 82 is connected to the branch air pipe 83, and the other end passes through the filter cartridge 3 and the bracket 31 and is connected to the external air pump. The branch air pipe 83 passes through the annular tube 81 and is connected to the annular tube 81 through the air hole. The annular tube 81 is provided with an opening facing upward. The micropores have an aperture of 1.0-1.5 mm. Air is introduced into the main air pipe 82 and the branch air pipe 83 through an external air pump, and then the air is discharged through the micropores on the annular tube 81. Combined with the set sound wave generator 85, the gas discharged into the sewage is broken up into bubbles as small as possible. The surface tension of the bubbles adsorbs small-sized particles, filaments, flocs and other wastes in the sewage, and these wastes are concentrated in the foam formed by the aggregation of the bubbles through the polymerization of the bubbles, thereby completing the filtration and cleaning of tiny wastes in the sewage.

[0046] In this embodiment, there are several annular tubes 81 with the same diameter. All the annular tubes 81 are concentrically arranged with the main air pipe 82 and the annular diameters decrease successively. Multiple groups of annular tubes 81 are arranged to increase the speed of bubble generation and accelerate filtration.

[0047] In this embodiment, an arc-shaped cover 91 is provided on the top of the floating weight cylinder 9, and the distance between the side wall of the floating weight cylinder 9 and the side wall of the filter cartridge 2 4 decreases from top to bottom. A sealing bottom plate 92 is provided at the bottom of the floating weight cylinder 9, and the sealing bottom plate 92 is sealed and connected to the inner wall of the filter cartridge 2 4. An elastic pad 93 is provided at the bottom of the floating weight cylinder 9, and the sealing bottom plate 92 is fixedly connected to the outer sleeve 72. A suction pipe 94 that passes through the filter cartridge 2 4 is provided on the floating weight cylinder 9. The floating weight cylinder 9 There is a gap between the filter cartridge 1 and the filter cartridge 2 4. As the annular tube 81 continuously enters the air, the sewage in the filter cartridge 1 3 will be pressed into the filter cartridge 2 4 by the air pressure through the connecting tube 5, and will flow to the sealing bottom plate 92 under the guidance of the arc cover 91. As the amount of water continues to increase, the elastic pad 93 will be pressed down to make the sealing bottom plate 92 drop, thereby causing the outer sleeve 72 and the adsorption rod 71 to drop. Under the suction action of the suction pipe 94, when the sewage water level in the filter cartridge 3 drops, the adsorption of the foam by the adsorption rod 71 can still be maintained.

[0048] Working principle: First, a certain amount of sewage is drawn out of the filter cartridge 3 from the sedimentation tank where sedimentation has been completed through the water pipe 2, and then air is introduced into the main air pipe 82 and the branch air pipe 83 through an external air pump, and then the air is discharged through the micropores on the annular tube 81. Combined with the set sound wave generator 85, the gas discharged into the sewage is broken up into bubbles as small as possible, and the surface tension of the bubbles adsorbs small-sized particles, filaments, floccules and other wastes in the sewage, and these wastes are concentrated in the foam formed by the aggregation of bubbles through the polymerization of bubbles, completing the filtration and cleaning of tiny wastes in the sewage. The foam floating on the water surface will be adsorbed and sucked through the adsorption rod 71. It is finally discharged under the suction action of the suction pipe 94. At the same time, as the air is continuously discharged from the annular tube 81, the air pressure in the filter cartridge 1 3 increases, and the sewage will be pressed into the filter cartridge 2 4 through the connecting tube 5, and flow to the sealing bottom plate 92 under the guidance of the arc cover 91. As the amount of water continues to increase, the elastic pad 93 will be pressed down to make the sealing bottom plate 92 drop, and then the outer sleeve 72 and the adsorption rod 71 will drop. Under the suction action of the suction pipe 94, when the sewage water level in the filter cartridge 1 3 drops, the adsorption of the foam by the adsorption rod 71 can still be maintained. Finally, the sewage entering the filter cartridge 2 4 will be discharged through the discharge pipe on the side of the filter cartridge 2 4 after filtering and cleaning the tiny waste in the water.

[0049] Based on the above, the present invention sets up a sedimentation tank, which can remove part of the waste in the wastewater by sedimentation; the bubble making structure sets up the bubbles discharged from the annular tube to disperse into tiny bubbles with a large specific surface area through ultrasonic vibration, and the small-sized waste in the wastewater is adsorbed by the surface tension of these tiny bubbles, and then the adsorbed waste will accumulate on the surface of the wastewater, and the tiny bubbles will aggregate to form foam, and the waste carriers will not enter the wastewater again, thus completing the cleaning of the tiny waste; the floating counterweight cylinder sets up will gradually press the adsorption rod downward under the gravity of the filtered wastewater, and can maintain the suction of the foam on the water surface after the water level is lowered, so as to remove the foam containing the waste as much as possible.

[0050] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the inventive concept and technical solution of the present invention, or the inventive concept and technical solution are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
