Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a food processing wastewater flotation and impurity removal treatment device. Background Art

[0002] The air contains oxygen. Air or oxygen is injected into the wastewater in the form of tiny bubbles through aeration equipment. As these bubbles rise in the water, oxygen is gradually transferred from the bubbles to the water, thereby increasing the dissolved oxygen content in the wastewater. Sufficient dissolved oxygen is essential for the survival and activity of aerobic microorganisms in the wastewater, because aerobic microorganisms need to consume oxygen when decomposing organic pollutants, and waste gas carries waste floating on the water surface.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , a food processing wastewater air flotation impurity removal treatment device, including a treatment tank 1, a moving assembly, a lifting assembly and a filtering assembly. A treatment cavity with an upper opening is provided on the treatment tank 1. The moving assembly includes support legs 2, a support frame 3, a cover body 4, a worm gear 5, a worm 6, a motor 7 and a screw rod 8. The support legs 2 are provided at the four corners above the treatment tank 1, the support frame 3 is provided above the four groups of support legs 2, the cover body 4 is provided on one side of the support frame 3, the worm 6 and two groups of worm gears 5 are provided inside the cover body 4, the worm 6 meshes with the two groups of worm gears 5, the output end of the motor 7 penetrates through the cover body 4 and is connected to the worm 6, two groups of screw rods 8 are also rotatably provided inside the support frame 3, the screw rods 8 penetrate through the support frame 3 and the cover body 4 and are connected to the center of the worm gear 5. The lifting assembly includes a sliding plate 9, a lifter 10 and a lifting plate 11. Two screw holes threadedly connected to the screw rods 8 are provided on the sliding plate 9. The lifter 10 penetrates through the sliding plate 9 and is connected to the lifting plate 11. The filtering assembly includes a guide block 12 and a filter frame 13. A guide groove adapted to the guide block 12 is provided below the lifting plate 11, and the filter frame 13 is also provided below the guide block 12. An aeration tank 16 is also provided on the bottom wall of the treatment tank 1.

[0024] First, introduce the food processing wastewater into the treatment chamber of treatment tank 1. Meanwhile, start the aeration tank 16 to inject air or oxygen into the wastewater for aeration operation, increasing the dissolved oxygen content in the wastewater and prompting impurities such as waste residue to gradually float to the water surface to form scum;

[0025] The support legs 2 provide stable support for the support frame 3, and the support frame 3 provides stable support for the cover body 4 and the screw rod 8. When starting the motor 7 (using a servo motor 7), the output end of the motor 7 rotates to drive the worm 6 to rotate. Since the worm 6 meshes with two groups of worm wheels 5 inside the cover body 4, the rotation of the worm 6 will cause the two groups of worm wheels 5 to rotate synchronously. And the center of the worm wheel 5 is connected to the screw rod 8 rotatably arranged in the support frame 3, so the rotation of the worm wheel 5 will drive the screw rod 8 to rotate. Two groups of screw holes threadedly connected to the screw rod 8 are provided on the sliding plate 9. According to the principle of screw drive, the rotation of the screw rod 8 will cause the sliding plate 9 to move in the horizontal direction. In this way, by controlling the rotation direction and angle of the motor 7, the position of the sliding plate 9 and the lifting assembly connected thereto in the horizontal direction can be accurately adjusted, so as to conveniently move the lifting assembly to a suitable position according to the distribution of the scum on the water surface in the treatment tank 1, etc., for effective collection and treatment of the scum in the subsequent process;

[0026] The lifting assembly mainly realizes the height adjustment of the filtering assembly in the vertical direction. When it is necessary to adjust the height of the filtering frame 13, start the lifter 10 (using a cylinder). The telescopic movement of the piston rod of the cylinder will drive the lifting plate 11 to move in the vertical direction. A guide rod 15 passing through the sliding plate 9 is provided above the lifting plate 11. The guide rod 15 plays a role of guiding and stabilizing, restricting the movement track of the lifting plate 11 in the vertical direction, ensuring that the lifting plate 11 will not shake, deviate, etc. during the lifting process, and can smoothly lift or lower the filtering frame 13 to the specified height position. In this way, according to factors such as the thickness of the scum on the water surface and the treatment requirements, the relative position between the filtering frame 13 and the water surface can be flexibly adjusted to better collect and treat the waste residue floating on the water surface.

[0027] In this embodiment, the guide block 12 is T-shaped, and the guide block 12 and the guide groove are arranged in two groups symmetrically. The filtering frame 13 with the guide block 12 is slidably connected to the lifting plate 11, which is convenient for disassembly and assembly, and the guide block 12 and the guide groove are arranged in two groups symmetrically. When installing the filtering assembly, insert the guide block 12 into the guide groove. The T-shaped guide block 12 can ensure the firmness of the connection, enabling the filtering frame 13 to accurately move in the vertical direction along with the lifting plate 11, realizing the reliable connection between the filtering assembly and the lifting plate 11. This detachable connection method is convenient for disassembling the filtering frame 13 from the lifting plate 11 when it is necessary to clean, replace the filtering frame 13 or centrally transport impurities. Just lift the filtering frame 13 upward to disengage the guide block 12 from the guide groove to complete the disassembly operation, and the operation is simple and convenient.

[0028] In this embodiment, the bottom wall of the filter box 13 is provided with an inclined surface 14, and a side opening is provided at the side opening end of the filter box 13 away from the guide groove. When the filter box 13 is at an appropriate height position, the wastewater will flow through the filter box 13. The filter box 13 can intercept solid impurities in the wastewater, so that when the wastewater passes through the filter box 13, the impurities are left in the box, realizing the preliminary separation of the wastewater and the impurities. The bottom wall of the filter box 13 is provided with an inclined surface 14, and a side opening is provided at the side opening end away from the guide groove. During the flotation impurity removal process, some lighter floating scum may adhere to the bottom wall of the filter box 13. Due to the existence of the inclined surface 14, these floating scum will gradually move along the inclined surface 14 towards the side opening under the action of buoyancy and other forces, and finally float to the water surface from the side opening, facilitating the subsequent centralized cleaning of the floating scum and preventing the impurities from accumulating in the filter box 13 and affecting the filtering effect.
