Description

Technical Field

[0001] This utility model relates to the field of oil residue treatment technology, and in particular to a directional collection device for scum and oil. Background Technology

[0002] During tunnel construction through coal-bearing strata, construction wastewater is frequently generated. This wastewater typically contains fine particulate matter and oily contaminants leaked from machinery. Because these contaminants are less dense than water, they easily form scum and oil films on the surface. Due to the characteristics of tunnel construction—large instantaneous drainage volumes and drastic water fluctuations—the amount of scum and oil generated is highly uncertain, making traditional treatment equipment unsuitable for direct application. Currently, manual dredging is commonly used for pretreatment, but this method suffers from high labor intensity and low efficiency.

[0003] A prior art device (Publication No.: CN108643146A), applicant: Guangzhou Saite Environmental Engineering Co., Ltd., application date: April 4, 2018, discloses a device for collecting floating oil and scum, including a sludge collection tank, a mounting bracket, and a scum scraping mechanism. The mounting bracket is installed on the upper side of the sludge collection tank, and the scum scraping mechanism is installed on the mounting bracket. When the scraper in the scum scraping mechanism rotates, it can collect the floating scum and oil on the liquid surface into the sludge collection tank. The upper part of the sludge collection tank is higher than the liquid surface. The sludge collection tank is equipped with a floating system that generates buoyancy with the liquid and supports the sludge collection tank, the mounting bracket, and the scum scraping mechanism. The floating system generates sufficient buoyancy to support the sludge collection tank, the mounting bracket, and the scum scraping mechanism, ensuring that the scum scraping mechanism remains stably at the liquid surface to adapt to changes in the liquid level. That is, the scum scraping mechanism can always collect floating scum and oil during operation, avoiding unnecessary work by the scum scraping mechanism and preventing a decrease in the working efficiency of the collection device.

[0004] However, the aforementioned existing technologies generally have low efficiency in collecting scum and oil. Utility Model Content

[0059] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0060] Example 1

[0061] As attached Figure 1 Appendix Figure 2 and appendix Figure 4-7 As shown in the attached diagram, this embodiment discloses a directional collection device for scum and oil, used to improve the collection efficiency of scum and oil. It mainly includes a mounting base 1, an auxiliary lifting component 3, a float component 6, an oil scum collection assembly 4, and a main discharge pipeline 51. In use, this embodiment is first placed in water with the collection port of the collection housing 41 facing upwards, as shown in the attached diagram. Figure 1 As shown; under the action of the float component 6, this embodiment can float stably on the water surface, and at the same time form a dynamic balance mechanism that is linked to the water level change in real time. That is, this embodiment can rise as the water level rises and fall as the water level falls. Then, the operator operates the auxiliary lifting component 33 to lower the connecting rod 43, which will sink the collection shell 41 to the corresponding height below the water surface, thereby facilitating the collection of scum and oil in this embodiment. Although there will be a momentary disturbance when the collection shell 41 is immersed in the water surface, the disturbance is negligible because the scum and oil will immediately reclam up again after the collection shell 41 is fully submerged in the water. The scum, oil, and water that have gathered above the collection housing 41 form a covering layer. After the external water pump (not shown in the figure) is started, the main discharge pipe 51 will form a continuous suction effect, so that the mixed fluid formed by the scum, oil, and water that has gathered at the discharge outlet 44 will be directionally transported to the inlet of the external water pump. At this time, a negative pressure vortex will be formed above the discharge outlet 44 of the collection housing 41. The radial flow field generated by the vortex can drive the surface scum and oil to gather rapidly towards the discharge outlet 44. After the mixed fluid enters the external water pump through the main discharge pipe 51, it will be transported to the matching collection container (not shown in the figure). This design improves the collection efficiency of scum and oil.

[0062] In the prior art, when the sludge scraping mechanism is running continuously, the scraper on it tends to disperse the floating oil and sludge in the collection area to the surrounding areas, resulting in the inability to effectively collect the floating oil and sludge. However, this embodiment utilizes the principle of fluid dynamics, which forms a negative pressure vortex above the outlet 44 of the collection shell 41. The radial flow field generated by this vortex can drive the surface floating oil and sludge to quickly gather towards the outlet 44. Therefore, the collection efficiency of the prior art for floating oil and sludge is generally lower than that of this embodiment.

[0063] The specific structure of the directional collection device for scum and oil is as follows: It includes a mounting base 1, in which a base frame 11 is provided, and an auxiliary lifting component 3 is directly or indirectly provided on the base frame 11; a float component 6 is provided on the lower side of the auxiliary lifting component 3; a collection shell 41 is provided in the oil scum collection assembly 4, which is located below the auxiliary lifting component 3, and a discharge port 44 is opened at the top of the collection shell 41; a connecting rod 43 is provided at the top of the collection shell 41, and one end of the connecting rod 43 is connected to the auxiliary lifting component 3; a main discharge pipe 51 is provided at the discharge end of the discharge port 44; an auxiliary lifting component 33 is provided in the auxiliary lifting component 3, and the auxiliary lifting component 33 is connected to the connecting rod 43. Compared with the prior art, this utility model improves the collection efficiency of scum and oil and avoids the risk of secondary environmental pollution to a certain extent, thus having high practicality.

[0064] In a specific application scenario, as shown in the appendix Figure 1 and appendix Figure 4 As shown, the auxiliary lifting component 3 is provided with a mounting frame 31. The left and right ends of the mounting frame 31 are directly or indirectly connected to the base frame 11. The mounting frame 31 is provided with four sets of auxiliary lifting components 33. These four sets of auxiliary lifting components 33 are arranged around the oil residue collection component 4. A connecting rod 43 is connected to a set of auxiliary lifting components 33. The position of the auxiliary lifting component 33 corresponds to the position of the connecting rod 43. This design improves the stability of the overall structure of this embodiment.

[0065] Furthermore, the auxiliary lifting component 33 can be an auxiliary lifting nut, with two auxiliary lifting nuts in a set, and the two auxiliary lifting nuts are stacked. The connecting rod 43 is a connecting screw, that is, the inner wall of the auxiliary lifting nut is threadedly connected to the outer wall of the connecting screw. In use, rotating four sets of auxiliary lifting nuts at the same time can quickly achieve the lifting operation of the collection housing 41. The fact that each set has two auxiliary lifting nuts is to achieve the following purpose: when one auxiliary lifting nut slips, rotating the other auxiliary lifting nut can also achieve the lifting operation of the collection housing 41. This design makes it easier for workers to lift and lower the collection housing, thus improving work efficiency to a certain extent.

[0066] In a specific application scenario, as shown in the appendix Figure 5As shown, the collecting shell 41 is generally cylindrical with an opening at the top. Four protrusions (not marked in the figure) extend from the outer peripheral wall of the collecting shell 41 for vertically mounting the aforementioned connecting rods 43, meaning there are four connecting rods 43. Furthermore, a semi-circular notch 42 is provided on the side of the collecting shell 41 near the connecting rods 43. During use, the collecting shell 41 does not need to be completely submerged in water; scum and oil can still flow into the discharge outlet 44 through the notch 42, further improving the collection efficiency of scum and oil. Additionally, the bottom wall of the collecting shell 41 can be conical, with the aforementioned discharge outlet 44 located in the middle of the bottom wall. During use, scum and oil are less likely to adhere to the bottom wall of the collecting shell 41, preventing scum and oil accumulation and improving the flow of scum and oil into the discharge outlet 44 to a certain extent.

[0067] In a specific application scenario, as shown in the appendix Figure 1 and appendix Figure 7 As shown, the float component 6 mainly includes floats 61 and limiting screws 63; there are four floats 61, which are arranged around the collection shell 41, and the outer wall of the floats 61 is provided with mounting holes 62; the bottom end of the limiting screws 63 passes through the mounting bracket 31 into the mounting holes 62, and the limiting screws 63 are threadedly connected to the mounting holes 62, and the number and position of the limiting screws 63 correspond to the number and position of the floats 61.

[0068] Furthermore, the mounting hole 62 can be a through hole, which reduces the buoyancy experienced in this embodiment. If the collection shell 41 is already below the scum and oil, the operator does not need to actively rotate the auxiliary lifting nut. This design reduces the workload of the operator and improves the collection efficiency of scum and oil in this embodiment to a certain extent.

[0069] Furthermore, as shown in the appendix Figure 4 As shown, the auxiliary lifting component 3 is also equipped with a positioning nut 32. Specifically, the positioning nut 32 is located at the top of the mounting bracket 31. The positioning nut 32 is threadedly connected to the limiting screw 63, and the number and position of the positioning nuts 32 correspond to the number and position of the limiting screw 63, which can stabilize the positional relationship between the float 61 and the limiting screw 63 to a certain extent. In addition, there is a distance between the positioning nut 32 and the auxiliary lifting nut. This design can prevent the float 61 from affecting the operation of the collecting shell 41 in collecting scum and oil.

[0070] In a specific application scenario, as shown in the appendix Figure 6As shown, this embodiment includes an oil sludge discharge assembly 5, which comprises a main discharge pipe 51 and an auxiliary discharge pipe 52. The left end of the main discharge pipe 51 is connected to the outlet 44, and the right end of the main discharge pipe 51 is connected to the auxiliary discharge pipe 52. That is, the end of the main discharge pipe 51 away from the outlet 44 is connected to an external water pump through the auxiliary discharge pipe 52. This design can utilize the buffering effect of the two pipes connected in series to discharge the sludge and oil more smoothly to the outside, reducing the risk of pressure fluctuations and leakage during the discharge process, and improving the working efficiency and safety of this embodiment to a certain extent.

[0071] Furthermore, the auxiliary discharge pipe 52 can be a flexible hose structure; the flexible hose structure is easy to disassemble and install, and is beneficial for maintenance and cleaning; at the same time, it can effectively adapt to complex working environments, which improves the flexibility and reliability of this embodiment to a certain extent.

[0072] Example 2

[0073] As attached Figure 1-3 As shown, this embodiment discloses a directional collection device for scum and oil, used to prevent larger foreign objects from entering the collection area of ​​the aforementioned embodiment 1. In addition to the components in embodiment 1, it also includes an interceptor 2. Specifically, the interceptor 2 is set on the base frame 11, and the top of the interceptor 2 is connected to the end of the auxiliary lifting component 3. This design can stabilize the position of the auxiliary lifting component 3 and, to a certain extent, block larger foreign objects from entering the outside of this embodiment. At the same time, the interceptor 2 further increases the volume of the overall structure of this embodiment, displacing more water and receiving greater buoyancy, which can reduce the probability that the entire structure of this embodiment will sink into the water.

[0074] Furthermore, as shown in the appendix Figure 3As shown, the interception component 2 includes a frame 21, a guide sleeve 23, and a screen 22. Specifically, the bottom surface of the frame 21 is constructed by interlacing several steel bars. The steel bars are located below the float component 6. The tops of the left and right sides of the frame 21 are fixedly connected to the ends of the auxiliary lifting component 3. There is no steel bar structure directly below the collecting housing 41, meaning that the auxiliary lifting nut allows the collecting housing 41 to descend to the area below the steel bars. In use, the steel bars can support the float 61, thereby reducing the probability that the float 61 will move away from this embodiment after detaching from the limiting screw 63. The steel bar structure further increases the volume of the overall structure of this embodiment, allowing more water to be discharged and greater buoyancy to be received, further reducing the probability that the entire structure of this embodiment will sink into the water. There are three sets of guide sleeves 23, with each set containing two guide sleeves 23, which are disposed on the outer side wall of the frame 21; the aforementioned mounting base 1 is provided with guide posts 12, which are vertically disposed on the base frame 11, and there are three of them. These three guide posts 12 are located on the left and right sides of the base frame 11, roughly as shown in the attached figure. Figure 2 As shown, a guide post 12 has a guide sleeve 23 penetrating its top, meaning the frame 21 is detachably connected to the mounting base 1. The position of the guide post 12 corresponds to the position of the guide sleeve 23, facilitating the replacement of the interception component 2. Additionally, the three sides of the frame 21 are partially composed of screens 22, roughly as shown in the attached diagram. Figure 3 As shown, during use, larger foreign objects are blocked outside the screen 22, but scum and oil can still move through the screen 22 to the collection area of ​​this embodiment, which improves the collection effect of scum and oil to a certain extent.
