Description

Technical Field

[0001] This utility model relates to the field of oil and water treatment technology, specifically to a float-type oil suction device. Background Technology

[0002] During tunnel construction, especially in sections where the surrounding rock joints and fissures are well-developed and the water inflow in the main tunnel and cross tunnels is significant, a considerable amount of construction wastewater is generated. This wastewater mainly includes bedrock fissure water, wastewater from drilling rigs, and wastewater generated during concrete spraying, pouring, and curing, as well as wastewater from equipment washing. The construction process generates wastewater with high concentrations of oily substances. If this oily construction wastewater is not collected and treated and is allowed to flow freely, it will cause varying degrees of pollution to the water environment near the inlet and outlet.

[0003] The conventional treatment method is to collect oily wastewater into a collection tank and separate it using an oil absorption device, such as the oil absorption device disclosed in CN202265814 U. It uses a sponge oil absorption layer for adsorption. However, the oil absorption layer on the sea surface is easily covered with floating oil after long-term operation, which reduces the adsorption efficiency and requires frequent replacement of the sponge oil absorption layer. Moreover, this device cannot properly adjust the distance between the oil-absorbing sponge and the water surface, and cannot accurately adsorb the oil layer, resulting in a high water content in the adsorbed oil and thus low oil absorption efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a float-type oil suction device. Based on the liquid level, the controller can control the drive motor to rotate forward and backward to cooperate with the gear and rack structure to drive the oil suction funnel to adjust its position up and down to meet different working conditions. It has high oil suction efficiency and long service life.

[0005] This utility model is achieved through the following technical solution:

[0006] A float-type oil suction device is provided, comprising a triangular mounting plate, with floats installed at each corner of the mounting plate. A fixed opening is provided at the center of the mounting plate, and an oil suction pipe is vertically installed within the fixed opening. An oil suction funnel is connected to the upper end of the oil suction pipe above the mounting plate, and an oil extraction hose is connected to the lower end of the oil suction pipe via an elbow. Three vertically spaced guide rods are circumferentially connected to the side of the oil suction funnel. Guide openings are provided on the mounting plate opposite each guide rod, and the guide rods are slidably positioned within the guide openings. A toothed rack is formed along the length of the side wall of the oil suction pipe. The bottom surface of the mounting plate... The suction pipe has a height adjustment mechanism connected to one side with a rack. The height adjustment mechanism includes a rotating shaft I that is rotatably mounted on the bottom surface of the mounting plate via a support I, and a rotating shaft II that is rotatably mounted on the bottom surface of the mounting plate via a support II. The rotating shafts I and II are arranged perpendicularly and intersecting each other. A gear that meshes with the rack is fixed between the two supports I. One end of the rotating shaft I passes through the support I and is connected to a worm gear. The part of the rotating shaft II facing the worm gear forms a worm that meshes with the worm gear. One end of the rotating shaft II passes through the support II and is connected to a motor. The motor is sealed and fixed to the bottom surface of the mounting plate through a motor housing.

[0007] Preferably, a counterweight is connected to the bottom surface of the mounting plate on the side opposite to the height adjustment mechanism.

[0008] By setting a counterweight on the bottom of the mounting plate, the weight of the height adjustment mechanism can be balanced, keeping the mounting plate level on the water surface and achieving uniform operation.

[0009] Furthermore, the upper circumferential edge of the oil suction funnel is vertically connected with multiple filter plates arranged at intervals, and the gaps between adjacent filter plates form a filter channel.

[0010] By setting filter plates on the upper circumferential edge of the oil suction funnel, the filter channels between adjacent filter plates serve as oil suction channels. At the same time, surface floating matter can be blocked to prevent it from being adsorbed into the oil suction funnel and causing blockage.

[0011] Furthermore, each filtration channel is inclined in a parallel manner.

[0012] The inclined filter channels help improve filtration efficiency, and have a better barrier effect than vertically set filter plates, thus improving filtration stability.

[0013] Furthermore, the motor housing is equipped with a rotating sealing ring at the through connection of the motor output shaft.

[0014] By setting a rotating sealing ring, a rotational seal can be achieved between the motor housing and the motor output shaft, improving the sealing performance of the motor housing and ensuring safe operation.

[0015] Furthermore, the motor housing is equipped with a controller electrically connected to the motor, as well as a DC power supply that powers the controller and the motor. The controller is also electrically connected to a liquid level sensor, which is installed on the upper edge of the oil suction funnel.

[0016] By installing a controller inside the motor housing, the motor can be rotated in both directions. Combined with the sensing function of the liquid level sensor, the position of the oil suction funnel can be automatically adjusted according to the liquid level, ensuring that it is always at the same level as the liquid surface, so as to guarantee the adsorption effect on the upper layer of floating oil.

[0017] The beneficial effects of this utility model are:

[0018] This invention utilizes a long rack and gear on the oil suction pipe, powered by a motor, to adjust the height of the oil suction funnel opening according to the thickness of the floating oil under different working conditions, ensuring it always maintains the optimal oil suction position. Combined with a liquid level sensor, it achieves automated dynamic adjustment, making operation convenient and guaranteeing the adsorption of floating oil on the water surface. It effectively reduces the water content in the oil-water mixture, improves oil suction efficiency, and expands the application range of the oil suction device. It can be used to clean various types of water bodies, including rivers, lakes, and oceans, thus improving work efficiency. Attached Figure Description

Detailed Implementation

[0026] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution. 1

[0027] like Figures 1-5 As shown, a float-type oil suction device includes a triangular mounting plate 1. A float 2 is installed at each corner of the mounting plate 1. A fixed opening 21 is provided at the center of the mounting plate 1, and an oil suction pipe 3 is vertically arranged within the fixed opening 21. The upper end of the oil suction pipe 3 is connected to an oil suction funnel 6 above the mounting plate 1. Multiple filter plates 23 are vertically connected at intervals along the upper circumferential edge of the oil suction funnel 6. The gaps between adjacent filter plates 22 form filter channels 24. To improve the filtration effect, each filter channel 24 is inclined and parallel to each other.

[0028] The lower end of the oil suction pipe 3 is connected to the oil suction hose 5 via an elbow 4. Three vertical guide rods 12 are equidistantly connected to the side of the oil suction funnel 6. Guide openings 22 are provided on the mounting plate 1, respectively, facing the guide rods 12. The guide rods 12 are slidably disposed in the guide openings 22. A rack 15 is formed along the length direction on the side wall of the oil suction pipe 3. A height adjustment mechanism is connected to the bottom surface of the mounting plate 1 on the side of the oil suction pipe 3 with the rack 15. A counterweight 14 is connected to the bottom surface of the mounting plate 1 on the side facing the height adjustment mechanism.

[0029] The height adjustment mechanism includes a rotating shaft I20 rotatably mounted on the bottom surface of the mounting plate 1 via a support I16, and a rotating shaft II13 rotatably mounted on the bottom surface of the mounting plate 1 via a support II11. The rotating shafts I20 and II13 are perpendicularly intersecting. A gear 17 meshing with a rack 15 is fixed between the two supports I16 on the rotating shaft I20. One end of the rotating shaft I20 passes through the support I16 and is connected to a worm gear 18. A worm 19 meshing with the worm gear 18 is formed on the portion of the rotating shaft II13 opposite to the worm gear 18. One end of the rotating shaft II13 passes through the support II11 and is connected to a motor 10. The motor 10 is sealed and fixed to the bottom surface of the mounting plate 1 via a motor housing 7. To ensure the sealing of the motor housing 7, a rotating sealing ring is provided at the point where the output shaft of the motor 10 passes through.

[0030] The motor housing 7 is equipped with a controller 9 that is electrically connected to the motor 10, and a DC power supply 8 that supplies power to the controller 9 and the motor 10. The controller 9 is also electrically connected to a liquid level sensor 25, which is installed on the upper edge of the oil suction funnel 6.

[0031] Considering that it may operate underwater for a long time, the rack 15, gear 17, shaft I20, shaft II13, support I16, support II11, etc. in this utility model can all be made of plastic parts, which can effectively prevent rusting and reduce weight without affecting the buoyancy of the float.

[0032] The working process of this utility model:

[0033] Before launching the float-type oil suction device of this invention, connect the oil suction hose 5 to the oil pump and then place it into the oily wastewater collection tank. The entire device can float on the water surface by means of three floats 2. The controller 9 in the motor box 7 on the bottom of the mounting plate 1 can control the drive motor 10 to reverse according to the signal sent by the liquid level sensor 25, and use the motor 10 to drive the rotating shaft II 13 to rotate. The worm gear 19 on the rotating shaft II 13 drives the worm wheel 18 to rotate, and the worm wheel 18 drives the gear 17 to drive the rack 15 to move, thereby driving the oil suction pipe 3 to move up and down in the fixed opening 21, adjusting the position of the upper oil suction funnel 6, so that the funnel opening of the oil suction funnel 6 is flush with the liquid surface, which facilitates the adsorption of floating oil and the water absorption. The circumferential guide rod 12 of the oil suction funnel 6 can limit and guide the oil suction pipe 3 to move up and down by means of the guide opening 22, ensuring the stability of the oil suction funnel 6 in raising and lowering.

[0034] The upper circumference of the oil suction funnel 6 is vertically connected to the filter plate 23. The gaps between the multiple filter plates 23 form a filter channel 24, which can effectively filter floating objects on the water surface and prevent floating oil from entering the funnel 6 and causing blockage of the oil suction funnel 6, thus effectively ensuring the stability of oil suction.

[0035] The oil-water mixture adsorbed by the oil suction funnel 6 is sent to the oil-water separation equipment through the oil suction hose 5 and the oil pump for secondary separation, which can achieve complete separation of oil and water. The separated water can be returned to the original collection tank. The secondary adsorption separation can effectively reduce the oil content in the collection tank, thus achieving complete oil-water separation.

[0036] This invention enables automatic collection of floating oil. After absorbing the oil, it automatically collects the oil into a designated container, reducing manual intervention. This invention is typically manufactured using environmentally friendly materials and will not cause secondary pollution to the environment during use.

[0037] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
