Description

Technical Field

[0001] This invention relates to the field of oil pollution cleaning technology for water collection wells, and particularly to an oil pollution absorption device for water collection wells. Background Technology

[0002] Hydropower station sump wells are located at the lowest point of the power plant to collect various wastewaters. The wastewater in the sump wells contains a large amount of grease. To prevent pollution to the natural environment, the grease and water in the sump wells need to be separated before the wastewater is discharged. The existing method for cleaning oil pollution in power plant sump wells mainly involves placing oil-absorbing cloths on the water surface to absorb the oil. However, this method has certain shortcomings:

[0003] First, the oil-absorbing cloth has a limited capacity to absorb oil stains. It will become saturated with oil stains in a very short time, so it needs to be replaced in a timely manner, which is inconvenient to use.

[0004] Secondly, the water collection well is quite deep, requiring the use of ropes to place the oil-absorbing cloth in the well, which makes it inconvenient for workers to place and retrieve the oil-absorbing cloth.

[0005] Finally, during the replacement of oil-absorbing cloths soaked with oil, the oil absorbed by the cloths can easily transfer to the workers' clothes, causing stains that are difficult to clean. Summary of the Invention

The outer wall of the liquid outlet groove is provided with a protective pad adapted to it.

[0009] Preferably, the inner wall of the box is provided with support frames on all four sides. The support frames are U-shaped structures. A filter core plate is placed on the top of the support frame. The filter core plate is adapted to the box and the support frame. The filter core plate is made of polyester fiber or glass fiber. A pull ring adapted to the filter core plate is provided in the middle of the top outer wall. The height of the pull ring is lower than the height of the liquid outlet pipe.

[0010] Preferably, a drain pipe is provided at the bottom of the outer wall of the box body away from the oil suction pipe, and an oil discharge pipe is provided at the top of the outer wall of the box body near the oil suction pipe. Both the drain pipe and the oil discharge pipe are equipped with control valves that are compatible with them. The height of the oil discharge pipe is lower than the height of the liquid outlet tank.

[0011] Preferably, the bottom outer wall of the box is provided with a water collection slope, the water collection slope is lower on the side near the drain pipe and higher on the side near the oil drain pipe, and the water collection slope is inclined from the oil drain pipe toward the drain pipe.

[0012] Preferably, a limiting ring is welded to the outer wall of the tank cover near the oil suction pipe. The limiting ring is adapted to the oil suction pipe and is sleeved on the outer wall of the oil suction pipe.

[0016] Preferably, a control handle is provided on the outer wall of the housing away from the telescopic hose, and the outer wall of the control handle is covered with a matching anti-slip sleeve.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] In this invention, during operation, the water collection well is opened, and then the telescopic hose, suction head, and tank are separated. The length of the telescopic hose is adjusted according to the water level so that the suction head can contact the water surface. When the suction head contacts the water surface, the floating block floats on the water surface under the action of buoyancy and directly contacts the oil sludge on the surface. Then, the water pump is started, and the oil sludge on the water surface is sucked into the tank through the suction pipe for storage through the suction head. Due to the buoyancy of the floating block, the suction head will not be submerged in the water. Therefore, the suction head only sucks up the oil sludge on the surface of the water, while there is less water below the oil sludge. In addition, the oil suction groove opened at the bottom of the floating block facilitates the oil sludge to collect into the suction head. Less water is absorbed along with the oil sludge, which can reduce the storage pressure in the tank. Compared with the oil-absorbing cloth method, it is not necessary to replace the oil-absorbing cloth frequently, and it can continuously absorb the oil sludge in the water collection well, avoiding the problems of frequent replacement of oil-absorbing cloth and limited oil absorption. At the same time, the operation is more convenient, and the oil sludge will not stick to the workers during the use of the device.

[0019] In this invention, oil absorbed through the suction pipe is discharged into the tank through the outlet channel. The oil slides down the inside of the tank onto the filter core plate. Under the gravity of the oil itself, the filter core plate separates the water and oil in the oil. The water permeates through the filter core plate to the bottom of the tank, while the oil is trapped above the filter core plate. Due to the difference in specific gravity between water and oil, the oil gradually rises to the top of the liquid surface, while the water falls to the bottom of the tank, thus completing the water-oil separation. Since the oil slides down the inner wall of the tank through the outlet channel, the continuous influx of oil into the tank will not cause fluctuations in the existing liquid level inside the tank. The oil and water can remain separated, preventing the oil from impacting from a height and causing water-oil mixing, making water-oil separation more convenient.

[0020] In this invention, water and oil are separated by a filter core plate. The settled water is discharged through a drain pipe. When the liquid level inside the tank reaches the height of the oil drain pipe, the oil at the top of the liquid surface is discharged through the oil drain pipe for collection, preventing excessive oil storage inside the tank from affecting oil absorption. Compared with oil-absorbing cloth, it can continuously absorb oil and is more convenient to use. The tank body and the tank cover are connected by connecting pins and connecting holes. The tank cover will not be opened during use. After the device is used, it is easy to separate the tank cover from the tank body for easy cleaning of the inside of the tank.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] refer to Figure 1-7 The oil sludge absorption device for the collection well shown includes a housing 1, a cover 2 on the top outer wall of the housing 1, which is inserted into the housing 1. An oil suction assembly is installed on the top of the cover 2 and is adapted to the cover 2. Universal wheels are bolted to all four sides of the bottom outer wall of the housing 1, and the universal wheels are equipped with matching locking components. The oil suction assembly includes an oil suction pipe 3 located at the center of the top outer wall of the cover 2, a telescopic hose 4 installed at the end of the oil suction pipe 3, and an suction head installed at the end of the telescopic hose 4. 5. The adsorption head 5 is inverted funnel-shaped. A floating block 6 is provided on the bottom outer wall of the adsorption head 5. The floating block 6 is adapted to the adsorption head 5. The floating block 6 is made of cross-linked foam material. Oil suction grooves 7 are evenly distributed on the bottom outer wall of the floating block 6. The oil suction grooves 7 are semi-circular. The oil suction grooves 7 are adapted to the floating block 6. A water pump 8 adapted to it is installed on the outer wall of the oil suction pipe 3. A control handle 24 is provided on the outer wall of the box 1 away from the telescopic hose 4. The outer wall of the control handle 24 is covered with an anti-slip sleeve 25 adapted to it.

[0031] With the above structure: During operation, the collection well is opened, and then the telescopic hose 4 and suction head 5 are separated from the tank 1. The length of the telescopic hose 4 is adjusted according to the water level so that the suction head 5 can contact the water surface. When the suction head 5 contacts the water surface, the float 6 floats on the water surface under the buoyancy and directly contacts the oil sludge on the surface. Then, the water pump 8 is started, and the oil sludge on the water surface is sucked into the tank 1 through the suction pipe 3 via the suction head 5 for storage. Due to the buoyancy of the float 6, the suction head 5 will not be submerged in the water. The adsorption head 5 absorbs the oil on the surface of the water, while there is less water below the oil. The oil absorption groove 7 at the bottom of the floating block 6 facilitates the oil to collect inside the adsorption head 5. Less water is absorbed along with the oil, which reduces the storage pressure in the tank 1. Compared with the oil absorption cloth method, it does not require frequent replacement of the oil absorption cloth and can continuously absorb oil in the water collection well, avoiding the problems of frequent replacement of oil absorption cloth and limited oil absorption. At the same time, it is more convenient to operate, and the oil will not stick to the staff during the use of the device.

[0032] like Figure 3 As shown, the oil suction pipe 3 penetrates the top of the tank cover 2. The end of the oil suction pipe 3 away from the telescopic hose 4 is connected to the liquid outlet pipe 9. Both ends of the liquid outlet pipe 9 are equipped with liquid outlet grooves 10, which are adapted to the tank body 1 and contact the inner wall of the tank body 1. The outer wall of the liquid outlet groove 10 is equipped with a protective pad 11 adapted to it. Support frames 12 are installed around the inner wall of the tank body 1. The support frames 12 have a "U"-shaped structure. A filter core plate 13 is placed on top of the support frame 12. The filter core plate 13 is adapted to both the tank body 1 and the support frame 12. The filter core plate 13 is made of polyester fiber or glass fiber. A pull ring 14 is installed in the middle of the top outer wall of the filter core plate 13, and the height of the pull ring 14 is lower than the height of the liquid outlet pipe 9. The oil absorbed by the suction pipe 3 is discharged into the tank 1 through the outlet tank 10. The oil slides down the inside of the tank 1 onto the filter core plate 13. Under the gravity of the oil itself, the filter core plate 13 separates the water and oil in the oil. The water permeates through the filter core plate 13 to the bottom of the tank 1, while the oil is trapped above the filter core plate 13. Due to the difference in specific gravity between water and oil, the oil gradually rises to the top of the liquid surface, while the water falls to the bottom of the tank 1, thus completing the water-oil separation. Since the oil slides down the inner wall of the tank 1 through the outlet tank 10, the oil continuously entering the tank 1 will not cause fluctuations in the existing liquid level inside the tank 1. The oil and water can remain separated, preventing the oil from impacting from a height and causing water-oil mixing, making water-oil separation more convenient.

[0033] like Figure 4As shown, a drain pipe 15 is installed at the bottom of the outer wall of the tank 1 away from the oil suction pipe 3, and an oil drain pipe 16 is installed at the top of the outer wall of the tank 1 near the oil suction pipe 3. Both the drain pipe 15 and the oil drain pipe 16 are equipped with corresponding control valves. The height of the oil drain pipe 16 is lower than the height of the liquid outlet tank 10. A water collection slope 17 is installed on the bottom outer wall of the tank 1. The horizontal position of the water collection slope 17 near the drain pipe 15 is lower, and the horizontal position of the water collection slope 17 near the oil drain pipe 16 is higher. The water collection slope 17 is inclined from the oil drain pipe 16 towards the drain pipe 15. Water and oil are separated by the filter core plate 13. The settled water is discharged through the drain pipe 15. When the liquid level inside the tank 1 reaches the height of the oil drain pipe 16, the oil at the top of the liquid surface is discharged through the oil drain pipe 16 for collection, preventing the tank 1 from storing too much oil and affecting the absorption of oil. Compared with the absorption of oil cloth, it can continuously absorb oil and is more convenient to use.

[0034] like Figure 1 As shown, a limiting ring 18 is welded to the outer wall of the box cover 2 near the oil suction pipe 3. The limiting ring 18 is adapted to the oil suction pipe 3 and is sleeved on the outer wall of the oil suction pipe 3. A fixing frame 19 is provided at the bottom of the outer wall of the box body 1 near the telescopic hose 4. The fixing frame 19 has an arc-shaped structure and is adapted to the suction head 5. The suction head 5 is snapped into the fixing frame 19. The limiting ring 18 and the fixing frame 19 facilitate the fixing of the oil suction pipe 3 and the suction head 5. When the device is working, the suction head 5 can be removed from the fixing frame 19 to adjust the length of the telescopic hose 4 and thus adjust the position of the suction head 5. After the oil is collected, the telescopic hose 4 can be shortened to retract the suction head 5. Finally, the suction head 5 can be fixed by hanging it on the fixing frame 19.

[0035] like Figure 5 As shown, the outer wall of the box body 1 is provided with an observation window 20, and both ends of the top outer wall of the box cover 2 are provided with handles 23, which are adapted to the oil suction pipe 3. The bottom outer wall of the box cover 2 is provided with connecting pins 21 around the perimeter, and the top outer wall of the box body 1 is provided with connecting holes 22 around the perimeter. The connecting pins 21 are inserted into the connecting holes 22, and the inner wall of the connecting holes 22 is provided with a sealing sleeve that is adapted to it. The box body 1 and the box cover 2 are connected by the connecting pins 21 and the connecting holes 22. The box cover 2 will not be opened during use. After the device is used, it is easy to separate the box cover 2 from the box body 1 to facilitate cleaning of the inside of the box body 1.

[0036] Working principle of this invention:

[0037] During operation, the water collection well is opened, and then the telescopic hose 4 and suction head 5 are separated from the tank 1. The length of the telescopic hose 4 is adjusted according to the water level so that the suction head 5 can contact the water surface. When the suction head 5 contacts the water surface, the floating block 6 floats on the water surface under the action of buoyancy and directly contacts the oil on the surface. Then the water pump 8 is started and sucks the oil on the water surface into the tank 1 through the suction pipe 3 for storage through the suction head 5. Due to the buoyancy of the floating block 6, the suction head 5 will not be immersed in the water. Therefore, the suction head 5 only sucks the oil on the surface, while there is less water below the oil. The oil suction groove 7 opened at the bottom of the floating block 6 facilitates the oil to collect into the suction head 5. The amount of water absorbed along with the oil is small, which can reduce the storage pressure in the tank 1. Compared with the oil-absorbing cloth method, it does not need to replace the oil-absorbing cloth frequently, and it can continuously absorb the oil in the water collection well, avoiding the problems of frequently replacing the oil-absorbing cloth and the limitation of the oil absorption volume. At the same time, the operation is more convenient, and the oil will not stick to the workers during the use of the device.

[0038] The oil absorbed by the suction pipe 3 is discharged into the tank 1 through the outlet tank 10. The oil slides down the inside of the tank 1 onto the filter core plate 13. Under the gravity of the oil itself, the filter core plate 13 separates the water and oil in the oil. The water permeates through the filter core plate 13 to the bottom of the tank 1, while the oil is trapped above the filter core plate 13. Due to the difference in specific gravity between water and oil, the oil gradually rises to the top of the liquid surface, while the water falls to the bottom of the tank 1, thus completing the separation of water and oil. Since the oil slides down the inner wall of the tank 1 through the outlet tank 10, the oil continuously entering the tank 1 will not cause fluctuations in the existing liquid surface inside the tank 1. The oil and water can remain separated, preventing the oil from impacting from a height and causing water and oil to mix, making the separation of water and oil more convenient.

[0039] Water and oil are separated by the filter core plate 13. The settled water is discharged through the drain pipe 15. When the liquid level inside the tank 1 reaches the height of the oil drain pipe 16, the oil at the top of the liquid surface is discharged through the oil drain pipe 16 for collection, preventing the tank 1 from storing too much oil and affecting the absorption of oil. Compared with oil-absorbing cloth, it can continuously absorb oil and is more convenient to use. The tank 1 and the tank cover 2 are connected by connecting pin 21 and connecting hole 22. The tank cover 2 will not be opened during use. After the device is used, it is easy to separate the tank cover 2 from the tank 1 for easy cleaning of the inside of the tank 1.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
