Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, and specifically, to an intermediate wastewater tank for treating oily wastewater. Background Art

[0002] Oily wastewater refers to the wastewater containing oil substances discharged during industrial production processes. These oil substances include natural petroleum, petroleum products, tar and its fractions, as well as edible animal and vegetable oils and fats, etc. Oily wastewater poses potential hazards to the environment and human health, so its treatment and management are crucial.

[0003] The treatment process of oily wastewater usually is as follows: First, large particles and floating oil in the wastewater are removed, then most of the oil droplets and suspended solids in the wastewater are removed by methods such as gravity separation or flotation. Next, biological treatment or chemical treatment methods are used to further degrade the organic matter and oil droplets in the wastewater. Finally, trace pollutants in the wastewater are removed by methods such as filtration, adsorption or membrane separation to ensure that the effluent quality meets the discharge standards.

[0004] Among them, for the device that uses biological treatment or chemical treatment methods to further degrade the organic matter and oil droplets in the wastewater, for example: the utility model patent with the existing publication number: CN217757104U. This device introduces the oily wastewater that has removed most of the oil droplets and suspended solids in the wastewater by methods such as gravity separation or flotation into the reaction tank through the connecting pipe from the filter box, and at the same time, medicaments are put in. Then the motor starts to drive the stirring rod to make the oily wastewater react fully with the medicaments, and then the oily wastewater is further treated in the filter box. However, when the oily wastewater passes through the filter box, since the grease in the oily wastewater remaining at the filter screen will solidify, it is very easy to block the filter screen along with the filtered impurities, and it often needs to be cleaned, which reduces the treatment efficiency of the oily wastewater.

The filter box 3 is fixedly connected to the top of the wastewater intermediate tank 1, and a plurality of filter holes are opened at the bottom of the filter box 3. The rotating shaft 4 with a rotating function is vertically arranged inside the filter box 3. The through-hole mechanism 003 is installed at the bottom of the rotating shaft 4, and the first cleaning plate 6 is arranged at the bottom of the through-hole mechanism 003 and is used to cooperate with the rotating shaft 4 and the through-hole mechanism 003 to clean the inner bottom wall of the filter box 3.

[0049] As Figures 1 - 2 shown in the figure, in this embodiment, the lifting mechanism 001 includes a lifting frame 7, a guiding rod 8, a lead screw 9, a second motor 10, a lifting plate 11, a connecting frame 12 and a first motor 5. The lifting frame 7 is fixedly connected to the outer top wall of the wastewater intermediate tank 1. The guiding rod 8 is fixedly connected to the lifting frame 7. The lead screw 9 is rotatably connected to the lifting frame 7. The second motor 10 is installed on the lifting frame 7, and the output end of the second motor 10 is fixedly connected to the lead screw 9. The lifting plate 11 is threadedly connected to the lead screw 9, and the lifting plate 11 is slidably sleeved on the guiding rod 8.

The rotating shaft 4 is rotatably connected to the connecting frame 12, and the output end of the first motor 5 is fixedly connected to the rotating shaft 4.

[0050] As Figures 1 - 2 shown in the figure, in this embodiment, the stirring mechanism 002 includes a third motor 13, a stirring shaft 14, stirring vanes 15 and a second cleaning plate 16. The third motor 13 is installed on the lifting plate 11. The stirring shaft 14 is rotatably connected to the lifting plate 11, and the output end of the third motor 13 is fixedly connected to one end of the stirring shaft 14. A plurality of stirring vanes 15 are fixedly connected to the stirring shaft 14, and a second cleaning plate 16 is fixedly connected to the top of each stirring vane 15.

[0051] As Figures 3 - 4 shown in the figure, in this embodiment, the through-hole mechanism 003 includes a disk 17, through-hole needles 18 and a baffle 19. The disk 17 is fixedly connected to the bottom of the rotating shaft 4. A plurality of through-hole needles 18 are fixedly connected to the bottom of the disk 17. When the plurality of through-hole needles 18 slide vertically in the filter box 3, the plurality of through-hole needles 18 respectively pass through the plurality of filter holes. The baffle 19 is elastically connected to the bottom of the disk 17, and a plurality of through-holes one for the through-hole needles 18 to pass through are opened on the baffle 19. Among them, the first cleaning plate 6 is fixedly connected to the bottom of the baffle 19, and a through-hole two for the through-hole needles 18 to pass through is opened on the first cleaning plate 6.

[0052] As Figure 5 shown, in this embodiment, it further includes: a first positioning block 20 and a second positioning block 21. The first positioning block 20 is fixedly connected to the top of the side wall of the rotating shaft 4, and the second positioning block 21 is fixedly connected to the connecting frame 12 for positioning after the first cleaning plate 6 is driven to rotate by the first motor 5.

[0053] As Figure 2 shown, in this embodiment, it further includes a limiting block 22. The limiting block 22 is fixedly connected to the stirring shaft 14. When the top of the limiting block 22 contacts the inner top wall of the waste water intermediate tank 1, the tops of the plurality of second cleaning plates 16 are in the same horizontal plane as the outer bottom wall of the filter box 3.

[0054] The working principle of the waste water intermediate tank for treating oily waste water is as follows: when the filter holes on the filter box 3 are blocked, the second motor 10 is started to drive the lead screw 9 to rotate, and then drive the lifting plate 11 to slide downward along the vertical direction on the guiding rod 8, and then drive the stirring mechanism 002 to move downward along the vertical direction in the waste water intermediate tank 1, and at the same time drive the connecting frame 12, the rotating shaft 4, the through hole mechanism 003 and the first cleaning plate 6 to move downward along the vertical direction in the filter box 3.

[0055] When the first cleaning plate 6 contacts the inner bottom wall of the filter box 3, the second motor 10 is shut down, and the first motor 5 is started to drive the rotating shaft 4 to rotate. After the side of the first positioning block 20 contacts the second positioning block 21, due to the limitation of the first positioning block 20 and the second positioning block 21, the operator reverses the first motor 5 to drive the rotating shaft to reverse. When the side of the first positioning block 20 contacts the other side of the second positioning block 21, the first motor 5 is rotated forward to drive the rotating shaft 4 to rotate, and the side of the first positioning block 20 contacts the second positioning block 21. Repeat the above cycle multiple times to drive the through hole mechanism 003 and the first cleaning plate 6 to rotate and clean the inner bottom wall of the filter box 3.

[0056] After the cleaning of the inner bottom wall of the filter box 3 is completed, the first motor 5 rotates to drive the rotating shaft 4 to rotate, so that the side of the first positioning block 20 contacts the second positioning block 21 to position the through hole mechanism 003, align the through hole needle 18 with the filter holes of the filter box 3, and then start the second motor 10 and shut down the first motor 5 at the same time to drive the lead screw 9 to rotate. Since the baffle 19 is elastically connected thereto, the connecting frame 12, the rotating shaft 4, the disc 17 and the through hole needle 18 are driven to move downward along the vertical direction in the filter box 3, while the first cleaning plate 6, the baffle 19 and the filter box 3 remain stationary. Then, the through hole needle 18 performs through hole treatment on the filter holes of the filter box 3 through the through hole one on the baffle 19 and the through hole two on the cleaning plate.

[0057] After the through-hole treatment is completed, the second motor 10 rotates in the reverse direction, driving the lead screw 9 to rotate in the reverse direction, and then driving the lifting plate 11 to slide upward along the guide bar 8 in the vertical direction. Further, the stirring mechanism 002 moves upward in the vertical direction in the waste water intermediate tank 1, and at the same time drives the connecting frame 12, the rotating shaft 4, the through-hole mechanism 003 and the first cleaning plate 6 to move upward in the vertical direction in the filter box 3.

[0058] When the limit block 22 contacts the inner top wall of the waste water intermediate tank 1, the second motor 10 is shut down, and the third motor 13 is started to drive the stirring shaft 14 to rotate, and then drive a plurality of stirring vanes 15 to rotate. At the same time, the second cleaning plate 16 fixedly connected to each stirring vane 15 is driven to clean the outer bottom wall of the filter box 3.

[0059] After the cleaning of the outer bottom wall of the filter box 3 is completed, the third motor 13 is shut down, and the second motor 10 is started to drive the lead screw 9 to rotate, and then drive the lifting plate 11 to slide downward along the guide bar 8 in the vertical direction. Further, the stirring mechanism 002 moves downward in the vertical direction in the waste water intermediate tank 1, and at the same time drives the connecting frame 12, the rotating shaft 4, the through-hole mechanism 003 and the first cleaning plate 6 to move downward in the vertical direction in the filter box 3, so that the device can be restored to the initial state.

[0060] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
