Description
Technical Field
[0001] This utility model belongs to the technical field of oil skimming equipment, specifically relating to an oil skimming device for removing floating oil from the surface of a liquid. Background Technology
[0002] Traditional oil skimmers for removing surface oil often employ fixed oil collection pipe structures, which are ill-suited to adapting to dynamic changes in oil levels. While existing technologies, such as the rotary skimmer disclosed in CN201920358U, incorporate a float structure, their adjustment mechanisms lack both manual and electric dual-mode control, leading to operational limitations during power outages or under special conditions. Particularly when processing oils containing significant impurities, the fixed-angle oil collection pipe is prone to reduced skimming efficiency due to level fluctuations, and the lack of an effective drive device at the sludge discharge end frequently results in oil sludge accumulation and blockage. Furthermore, the complex rotary support structure and difficult maintenance inherent in existing devices limit the long-term operational stability of the equipment. Utility Model Content
[0003] The purpose of this invention is to provide an oil skimming device for removing floating oil from the surface of a liquid, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an oil skimming device for removing floating oil from the surface of a liquid, comprising:
[0005] The fixed plate has two fixed plates, and an oil collection pipe is rotatably provided between the inner sides of the two fixed plates. One end of the oil collection pipe can be moved through to the outer side of one of the fixed plates to discharge oil residue. The rear sides of the two fixed plates are provided with floats through positioning frames to adjust the oil collection pipe according to the oil level.
[0006] The two fixed plates are provided with a manual or electric integrated opening and closing mechanism for manually or electrically adjusting the float. The fixed plate at one end of the oil collection pipe is provided with a drive motor for driving the oil collection pipe to rotate or swing.
[0007] Preferably, one side of each of the two fixed plates is provided with a rotary shaft support through which one end of the oil collecting pipe passes and a support shaft support that fixes the other end of the oil collecting pipe to rotate, which ensures the stable rotation of the oil collecting pipe during operation and avoids the oil collecting pipe from shaking or shifting due to unstable installation, thereby ensuring the accuracy and stability of the oil skimming operation.
[0008] Preferably, the bottom of the support shaft seat is provided with a threaded limiting block that limits the rotation of one end of the oil collecting pipe. When the oil collecting pipe rotates to skim oil, it can prevent the oil collecting pipe from rotating excessively and ensure that the oil collecting pipe is always at the optimal skimming angle.
[0009] Preferably, a gear is fixedly fitted onto the surface of one end of the oil collection pipe for slag discharge, and a main gear is provided on the drive motor shaft that meshes with the gear to drive the oil collection pipe to rotate and perform the oil skimming action. The gear drives the gear on the oil collection pipe to rotate, thereby driving the oil collection pipe to rotate and perform the oil skimming action. This gear transmission method can provide stable and precise power transmission.
[0010] Preferably, the front end of the oil collecting pipe is laterally provided with an oil collecting port that skims grease from the liquid surface into the oil collecting pipe and discharges it from one side. This allows the oil collecting pipe to effectively collect floating oil from the surface of the oil during rotation. The lateral arrangement of the oil collecting port increases the oil collecting area. Compared with some small-area or poorly designed oil collecting structures, it can collect floating oil more quickly and comprehensively, greatly improving the working efficiency of the oil skimming device.
[0011] Preferably, one end of the lead screw of the manual-automatic electric gate opener is rotatably mounted at the end of the float, and the positioning frame on one side of the float is guided and positioned behind the fixed plate, so that the float can be adjusted according to the oil level. Under normal circumstances, the extension and retraction of the lead screw can be precisely controlled by the manual-automatic electric gate opener in electric mode, thereby quickly and accurately adjusting the height of the float, and thus driving the oil collection pipe to adapt to changes in the liquid level.
[0012] Compared with the prior art, the technical effects and advantages of this utility model are: this oil skimming device for removing floating oil from the surface of liquids...
[0013] The float in this device can be adjusted automatically or manually according to the liquid level. Under normal operating conditions, the electric mode uses a manual-automatic electric hoist to precisely control the extension and retraction of the screw, quickly and accurately adjusting the float height and driving the oil collection pipe to adapt to changes in liquid level. In the event of a power failure or special operating conditions, switching to manual mode still allows operation, preventing the equipment from failing due to power problems and greatly improving the adaptability and flexibility of the equipment under complex operating conditions.
[0014] This invention achieves efficient oil skimming and effectively prevents clogging through the design of the oil collecting pipe. The horizontally opened oil collecting port increases the oil collecting area, enabling faster and more comprehensive collection of floating oil compared to small-area or poorly designed oil collecting structures, significantly improving skimming efficiency. Simultaneously, the slag discharge end of the oil collecting pipe meshes with the main gear of the drive motor via gears, achieving stable and precise power transmission to drive the oil collecting pipe to rotate and perform the skimming action. This effectively avoids the accumulation and clogging of oil sludge caused by the lack of an effective driving device, solving the problems of decreased skimming efficiency and poor slag discharge in existing devices when processing oils containing many impurities.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This utility model provides a technical solution: an oil skimming device for removing floating oil from the surface of a liquid, comprising:
[0021] Fixed plates 1 ensure the stability of the device during operation. Two fixed plates 1 cooperate to limit the rotation space of the oil collection pipe 2, ensuring that the oil collection pipe 2 can stably perform oil skimming operations. There are two fixed plates 1, which are arranged in parallel. The inner side is used to install the oil collection pipe 2, and it is rotatably connected to the oil collection pipe 2 through the rotary shaft support 8 and the support shaft seat 9. The rear side of the fixed plate 1 is connected to the positioning frame 4, which is used to install the float 5, thereby realizing the adjustment of the height of the oil collection pipe 2. The ends of the fixed plates 1 extend outward and are connected to the manual and automatic electric hoist 6, which is used to control the raising and lowering of the float 5. The oil collection pipe 2 is rotatably installed between the inner sides of the two fixed plates 1, which is responsible for collecting the floating oil on the liquid surface and discharging it.
[0022] The oil collecting pipe 2 rotates under the drive of the drive motor 7. The oil collecting port 13, horizontally opened at the front end, skims grease from the liquid surface into the pipe, then discharges it from one end, completing the skimming process. One end passes through one of the fixed plates 1 via a rotating shaft support 8, achieving a rotatable connection so that the oil skimming action can be performed under the action of the drive motor 7. The other end is fixed to another fixed plate 1 via a support shaft seat 9, also achieving a rotatable connection. Simultaneously, the threaded limiting block 10 at the bottom of the support shaft seat 9 limits the rotation of this end of the oil collecting pipe 2. A fixed gear 11 is sleeved on the surface of one end of the oil collecting pipe 2 for sludge discharge, which meshes with the main gear 12 on the shaft of the drive motor 7. The rotation of the oil collecting pipe 2 is achieved through gear transmission. One end of the oil collecting pipe 2 can be moved through to the outside of one of the fixed plates 1 for oil sludge discharge. The rear sides of the two fixed plates 1 are equipped with floats 5 for adjusting the oil collecting pipe 2 according to the oil level through positioning frames 4. The positioning frames 4 play a positioning and guiding role for the floats 5, ensuring that the floats 5 can maintain a stable running trajectory when adjusting the height according to the oil level, avoiding shaking or deviation, thereby ensuring that the oil collecting pipe 2 can accurately adjust its height with the change of liquid level.
[0023] One end of the positioning frame 4 is fixed to the rear side of the fixing plate 1, and the other end is used to install the float 5. One side of the float 5 is embedded in the positioning frame 4 and can move up and down along the guide of the positioning frame 4. The float 5 senses the change in oil level through its own buoyancy and transmits this change to the oil collection pipe 2, so that the oil collection pipe 2 can automatically adjust according to the oil level. At the same time, with the assistance of the manual-automatic electric gate opener 6, the height of the oil collection pipe 2 can be further precisely adjusted so that it is always in the optimal oil skimming position. The float 5 is indirectly connected to the fixing plate 1 through the positioning frame 4 and can move up and down within the positioning frame 4. One end of the screw of the manual-automatic electric gate opener 6 is rotatably set at the end of the float 5. When the screw extends or retracts, it drives the float 5 to rise and fall, thereby adjusting the height of the oil collection pipe 2.
[0024] Two fixed plates 1 extend outwards from their ends and are equipped with a manual-automatic electric hoist 6 for manually or electrically adjusting the float 5, providing power for raising and lowering the float 5 and achieving precise adjustment of the height of the oil collection pipe 2. It has both manual and electric operation modes. Under normal circumstances, the electric mode can precisely control the extension and retraction of the screw to quickly and accurately adjust the height of the float 5. In case of power failure or special working conditions, it can be switched to manual mode to ensure the normal operation of the device. A drive motor 7 is provided on the outer side of the fixed plate 1 at one end of the oil collection pipe 2 to drive the oil collection pipe 2 to rotate or swing, providing power for the rotation of the oil collection pipe 2 to perform oil skimming. By controlling the speed and direction of the drive motor 7, the rotation speed and angle of the oil collection pipe 2 can be precisely controlled, improving the oil skimming efficiency and quality. The main gear 12 on the shaft of the drive motor 7 meshes with a gear 11 fixed to the surface of the slag discharge end of the oil collection pipe 2, driving the oil collection pipe 2 to rotate through gear transmission.
[0025] One of the two fixed plates 1 has a rotary shaft support 8 on its corresponding side, which allows one end of the oil collecting pipe 2 to pass through and rotate, and a support shaft seat 9 that fixes the other end of the oil collecting pipe 2 to rotate. The rotary shaft support 8 allows one end of the oil collecting pipe 2 to pass through smoothly and achieve a rotatable connection, providing support and positioning for the rotation of the oil collecting pipe 2, ensuring the stability of the oil collecting pipe 2 during rotation, and reducing shaking and deviation. It is fixed on the corresponding side of one of the fixed plates 1. One end of the oil collecting pipe 2 passes through the rotary shaft support 8 to achieve a rotatable connection. The support shaft seat 9 plays a role in fixing and supporting the other end of the oil collecting pipe 2. It cooperates with the rotary shaft support 8 to ensure that the oil collecting pipe 2 can rotate stably during operation. At the same time, it provides an installation position for the threaded limit block 10. It is fixed on the corresponding side of the other fixed plate 1. The other end of the oil collecting pipe 2 is rotatably connected to the support shaft seat 9. The threaded limit block 10 is installed at the bottom of the support shaft seat 9.
[0026] The bottom of the support shaft seat 9 is provided with a threaded limiting block 10 to limit the rotation of one end of the oil collecting pipe 2. This limits the rotation of one end of the oil collecting pipe 2, preventing excessive rotation during oil skimming and ensuring that the oil collecting pipe 2 is always at the optimal skimming angle. When the oil level changes, the rotation range of the oil collecting pipe 2 can be adjusted by adjusting the threaded limiting block 10, improving the adaptability of the oil skimming device to different working conditions. It is installed at the bottom of the support shaft seat 9 and contacts one end of the oil collecting pipe 2. Adjusting its position limits the rotation angle of the oil collecting pipe 2.
[0027] A gear 11 is fitted and fixed to the surface of one end of the oil collecting pipe 2 for slag discharge. This gear meshes with the main gear 12 on the shaft of the drive motor 7, transmitting power and converting the rotational motion of the drive motor 7 into the rotation of the oil collecting pipe 2. This causes the oil collecting pipe 2 to perform an oil skimming action. The drive motor 7 shaft is equipped with a main gear 12 that meshes with the gear 11 to drive the oil collecting pipe 2 to rotate and perform the oil skimming action. This main gear 12 serves as a transmission component between the drive motor 7 and the oil collecting pipe 2, transmitting the power of the drive motor 7 to the gear 11, which in turn drives the oil collecting pipe 2 to rotate. Through gear transmission, stable and precise power transmission can be provided, improving the controllability of the rotation of the oil collecting pipe 2.
[0028] The front end of the oil collecting pipe 2 is laterally provided with an oil collecting port 13, which skims the grease on the liquid surface into the oil collecting pipe 2 and discharges it from one side. This is the key part of the oil collecting pipe 2 for collecting floating oil on the liquid surface. The laterally provided oil collecting port 13 increases the oil collecting area, which can skim the grease on the liquid surface into the oil collecting pipe 2 more quickly and comprehensively, thereby improving the working efficiency of the oil skimming device. It is installed on the rotating shaft of the drive motor 7 and meshes with the gear 11 at the slag discharge end of the oil collecting pipe 2.
[0029] The lead screw of the manual-automatic electric gate opener 6 is rotatably mounted at the end of the float 5, and the positioning frame 4 on one side of the float 5 is guided and positioned on the rear side of the fixed plate 1.
[0030] Specifically, during use, the float 5 senses changes in the oil level using its own buoyancy. When the level changes, the float 5 will rise or fall accordingly. Since the float 5 is connected to the fixed plate 1 via the positioning frame 4, and one end of the screw of the manual / automatic electric gate opener 6 is rotatably located at the end of the float 5, under normal circumstances, the screw can be precisely controlled to extend and retract in electric mode, driving the float 5 to rise and fall, thereby adjusting the height of the oil collection pipe 2. In case of special working conditions such as power failure, switching to manual mode can also be used to ensure that the oil collection pipe 2 always maintains the optimal relative position with the oil level, adapting to dynamic changes in the oil level.
[0031] After the drive motor 7 starts, the main gear 12 on its shaft rotates accordingly. The main gear 12 meshes with the gear 11, which is fixedly fitted onto the surface of the slag discharge end of the oil collecting pipe 2. Through gear transmission, the power of the drive motor 7 is transmitted to the oil collecting pipe 2, causing it to rotate. The oil collecting port 13, which is laterally opened on the front end face of the oil collecting pipe 2, sweeps across the liquid surface during rotation. Because the oil collecting port 13 increases the oil collecting area, it can quickly and comprehensively skim the grease on the liquid surface into the oil collecting pipe 2. As the oil collecting pipe 2 continues to rotate, the collected grease is discharged from one end of the oil collecting pipe 2, completing the skimming process. At the same time, the threaded limiting block 10 at the bottom of the support shaft seat 9 limits the rotation of the oil collecting pipe 2 to prevent excessive rotation and ensure that the oil collecting pipe 2 is always at the optimal skimming angle to adapt to different liquid levels and skimming conditions.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
