Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, and particularly relates to an oil floating aggregation mechanism with an oil blowing function and a wastewater oil removal system. Background Art

[0002] In a wastewater treatment system, before the wastewater enters the aerobic treatment link and the anaerobic treatment link, it is generally necessary to filter out impurities first, and then precipitate through a supernatant tank, so that the sludge in the wastewater precipitates to the bottom of the supernatant tank, and the precipitated water body enters other treatment links through an overflow channel.

[0003] During the precipitation of the wastewater in the supernatant tank, not only will there be a problem of sludge sinking to the bottom, but also the oil in the wastewater will float to the surface. At present, a rotary oil scraper is generally used to push the oil on the surface of the supernatant tank, and an oil collector is arranged on the pool wall of the supernatant tank. The continuously rotating oil scraper will push the oil into the oil collector to prevent the oil from entering the subsequent wastewater treatment link along with the wastewater. However, for the existing rotary oil scraper, after the oil is pushed, only part of it is pushed into the oil collector, and quite a part of the oil will continuously move in the supernatant tank along with the rotation of the oil scraping mechanism. The oil scraping effect is not good, resulting in part of the oil entering the subsequent wastewater treatment link and affecting the subsequent wastewater treatment.

[0004] Based on the above background, the inventor designed an oil floating aggregation mechanism with an oil blowing function and a wastewater oil removal system, aiming to solve the problem of poor oil removal effect of the current oil scraping structure.

[0045] The present utility model will be described in detail below by referring to the drawings and in conjunction with embodiments.

[0046] Embodiment 1

[0047] As Figure 2 shown, this embodiment provides an oil floating aggregation mechanism with an oil blowing function, including a first rotating assembly, a second rotating assembly, and a driving assembly for driving the first rotating assembly and the second rotating assembly to rotate synchronously and in opposite directions;

[0048] It further includes two groups of oil scraping assemblies respectively fixed on the first rotating assembly and the second rotating assembly and rotating synchronously therewith;

[0049] The oil scraping assembly includes an oil scraping rod barrel with a hollow cavity, and a blowing mechanism whose air outlet end is communicated with the hollow cavity of the oil scraping rod barrel;

[0050] A plurality of air outlet structures communicated with the hollow cavity and distributed along the axial direction thereof are provided on the oil scraping rod barrel.

[0051] As Figure 1 shown, in the prior art, the oil scraper rotates continuously in the same direction. Although the grease attached to the water surface will be aggregated by the oil scraper, only part of the floating oil enters the waste oil collector every time it rotates one week, and the oil scraping effect is not good.

[0052] As Figure 2 shown, in this embodiment, by setting a first rotating component and a second rotating component that can rotate synchronously in opposite directions, and setting an oil scraping component fixed on the first rotating component and the second rotating component, the two oil scraping components can complete the floating oil gathering action of first moving away from each other and then approaching each other through the reverse rotation of the first rotating component and the second rotating component. The oil scraping rod cylinder, through the air supply mechanism connected thereto, enables the air outlet structure provided thereon to blow the floating oil gathered between the two oil scraping rod cylinders, so that the floating oil is blown into the set oil collecting structure to complete an oil removal action. After the floating oil continues to accumulate, the driving component drives the first rotating component and the second rotating component to rotate in the direction opposite to that of the previous oil removal action, and again completes the floating oil gathering action of first moving away from each other and then approaching each other, and then uses the air outlet structure to blow the floating oil so that it is collected by the oil collecting structure. By repeating the above action process, the oil removal action of the supernatant tank of the wastewater treatment system can be continuously completed.

[0053] Therefore, the core of this application lies in that the oil scraping rod cylinders of the two oil scraping components have the function of gathering floating oil. At the same time, they can blow the floating oil with air, forming an oil removal concept of first gathering oil and then blowing oil. Moreover, the oil scraping rod cylinder is in direct contact with the floating oil, and the oil blowing effect is good. The structure of the entire mechanism is simple, stable and reliable. Compared with the prior art, the oil removal action is efficient, and the single oil removal effect is thorough. It can effectively solve the problem of poor oil scraping effect caused by the single rotation of the current oil scraper.

[0054] Specifically, in this embodiment, as Figure 2 shown, the driving component includes a horizontally arranged driving motor and a driving bevel gear arranged on the output shaft of the driving motor;

[0055] The first rotating component includes a first rotating sleeve and a first driven bevel gear installed on the first rotating sleeve;

[0057] The first rotating sleeve and the second rotating sleeve are coaxially arranged;

In this embodiment, the first driven bevel gear and the second driven bevel gear have the same structure, and the transmission ratio between the driving bevel gear and the first driven bevel gear is equal to the transmission ratio between the driving bevel gear and the second driven bevel gear. When the driving bevel gear rotates, it can drive the first driven bevel gear and the second driven bevel gear to rotate in opposite directions, thereby driving the first rotating sleeve and the second rotating sleeve to rotate in opposite directions, and further causing the two oil scraping plates to repeatedly move away from and approach each other. In this embodiment, the driving motor can be a servo motor or a stepper motor.

[0060] Specifically, in this embodiment, as Figure 2 shown, it further includes a vertically arranged fixed shaft;

[0062] The second rotating sleeve is installed on the first rotating sleeve and is rotatably connected thereto.

[0063] Specifically, in this embodiment, the first driven bevel gear and the second driven bevel gear have the same structure;

[0064] The transmission ratio between the first driven bevel gear and the driving bevel gear is equal to the transmission ratio between the second driven bevel gear and the driving bevel gear. In this embodiment, the transmission ratio is 1.

[0065] Specifically, in this embodiment, the oil scraping component further includes a support rod with ends fixed on the first rotating component and the second rotating component;

[0066] The air supply mechanism is a blower fixed on the support rod;

[0067] The oil scraping rod barrel is fixed on the support rod or the blower. In this embodiment, the oil scraping rod barrel is fixed on the blower, and the blower is fixed on the support rod, and the blower will rotate with the oil scraping rod barrel and the support rod. In some embodiments, the blower can also be fixed, and a corrugated hose can be used for air supply.

[0068] Specifically, in this embodiment, the oil scraping rod barrels are all in an L shape, ensuring that the oil scraping rod barrels are at a lower position relative to structures such as the blower, which is convenient for oil scraping;

[0069] The shape of the outer peripheral wall of its cross-section is any one of a triangle, a trapezoid, a circle, and a rectangle. In this embodiment, the shape of the outer peripheral wall of its cross-section is an isosceles triangle. In some embodiments, the outer peripheral shape of its cross-section can also be a rectangle, a trapezoid, a circle, or other shapes, which will not be elaborated here.

[0070] Specifically, in this embodiment, as Figure 2 shown, the air outlet structure on the oil scraping rod barrel is an air outlet branch pipe, and the air outlet branch pipes are uniformly distributed along the axial direction of the oil scraping rod barrel;

[0071] Air outlet branch pipes are arranged on both sides of the oil scraping rod barrel;

[0072] The air outlet direction of the air outlet branch pipe is horizontal and biased towards the free end of the oil scraping rod barrel, which can improve the effect of blowing the floating oil towards the oil collecting structure.

[0073] Specifically, in this embodiment, the included angle range between the air outlet direction of the air outlet branch pipe and the axis of the oil scraping rod barrel is: 15° to 75°. In this embodiment, the included angle between the air outlet direction of the air outlet branch pipe and the axis of the oil scraping rod barrel is 30°. Technicians can set other angles such as 45° and 60° according to needs, which will not be elaborated here.

[0074] In some embodiments, the included angle between several air outlet branch pipes and the axis of the oil scraping rod barrel can gradually increase along the direction close to the free end of the oil scraping rod barrel.

[0075] Specifically, in this embodiment, the air outlet branch pipes on both sides of the oil scraping rod barrel are mirror-symmetrically arranged with the axis of the oil scraping rod barrel as the symmetry axis, ensuring that the air outlet branch pipes can efficiently blow the floating oil in both the forward and reverse rotations of the driving motor, so that it moves towards the oil inlet end of the oil collecting structure.
