[0003] However, in actual working conditions, thin oil pumps are used to collect oil-water mixtures that need to be reused. Since different impurities are often mixed in the secondary oil-water mixture, the existing thin oil pumps only collect the secondary oil-water mixture and let it settle for a period of time before separating the oil and water. However, settling for a period of time is not enough to screen out the impurities in the oil-water mixture, resulting in the thin oil pump outputting oil or water containing 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Figure 1 A schematic diagram of the multifunctional thin oil pump of this utility model is shown. Figure 2 A schematic diagram of the box structure in this utility model is shown. Figure 3 A cross-sectional view of the multifunctional thin oil pump of this invention is shown. Figure 4 A schematic diagram of the oil suction mechanism in this invention is shown. Figure 5 A cross-sectional view of the gear pump of this invention is shown. Figure 6 A schematic diagram of the pumping mechanism in this utility model is shown. The multifunctional thin oil pump includes: a housing 1, an oil suction mechanism 2, and a water pumping mechanism 3. The housing 1 has a hollow cavity 10, and a first partition 11 is provided inside the hollow cavity 10. The first partition 11 divides the hollow cavity 10 into a filter cavity 12 and a flow cavity 13. The first partition 11 is provided with a flow hole 111, and the filter cavity 12 communicates with the flow cavity 13 through the flow hole 111. The oil suction mechanism 2 and the water pumping mechanism 3 are also shown. The water pumping mechanism 3 is installed on the upper surface of the housing 1. The oil suction end of the oil suction mechanism 2 extends into the flow cavity 13, and the oil suction end of the oil suction mechanism 2 is located in the middle region of the flow cavity 13. The water pumping mechanism 3 includes a detection unit 31 and a water pumping unit 32. The detection end of the detection unit 31 extends into the flow cavity 13, and the water suction end of the water pumping unit 32 extends into the flow cavity 13, and the water suction end of the water pumping unit 32 is located in the bottom region of the flow cavity 13. In this embodiment, the hollow cavity 10 is divided into the flow cavity 13 and the filter cavity 12. The fluid first enters the filter cavity 12, that is, the fluid is pre-treated by the filter cavity 12 to filter the impurities carried by the fluid. This achieves efficient impurity separation through a graded cavity structure, reducing the risk of impurities carried by the fluid entering the flow cavity 13 and reducing the risk of equipment wear caused by impurities being sucked in by the oil suction mechanism 2 and the water pumping mechanism 3. Since the fluid is an oil-water mixture, when the oil-water mixture enters the flow chamber 13, the oil and water have different densities, so the oil floats on the water surface. That is, when the oil and water volumes are the same, the water will remain in the bottom region of the flow chamber 13, and the oil will remain in the middle region of the flow chamber 13. The end of the water pumping mechanism 3 is located in the bottom region of the flow chamber 13, and the water pumping mechanism 3 can remove water in time. The oil suction end of the oil suction mechanism 2 is located in the middle region of the flow chamber 13, ensuring that the oil suction mechanism 2 can remove oil in time, achieving efficient oil-water separation and improving the purity of the liquid pumped away by the oil suction mechanism 2 and the water pumping mechanism 3.

[0021] Furthermore, a second partition 121 is provided in the filter chamber 12. The second partition 121 is located at the center of the filter chamber 12 and divides the filter chamber 12 into a first sub-filter chamber 122 and a second sub-filter chamber 123. In this embodiment, the second partition 121 is a rectangular flat plate, vertically installed at the center of the filter chamber 12, dividing the filter chamber 12 laterally into two sub-chambers of equal volume, namely, the first sub-filter chamber 122 and the second sub-filter chamber 123. The height of the second partition 121 is slightly lower than the height of the interior of the housing 1, meaning that the top of the first sub-filter chamber 122 and the top of the second sub-filter chamber 123 are interconnected. When fluid enters the first sub-filter chamber 122 from the top, the filtered fluid enters the first sub-filter chamber 122 from the top inlet and flows downward under the action of gravity. Since the fluid stays in the first sub-filter chamber 122 for a long time, large particles of impurities can be deposited to the bottom of the first sub-filter chamber 122 by their own gravity, and preliminary filtration is carried out. The fluid completes coarse filtration in the first sub-filter chamber 122, reducing the load on the second sub-filter chamber 123.

[0022] Furthermore, a filter 1231 is provided in the second sub-filter chamber 123, and the filter 1231 is detachably mounted on the first partition 11 based on the flow hole 111. The output end of the filter 1231 is installed in the flow hole 111 to ensure that the liquid entering the flow chamber 13 from the second sub-filter chamber 123 must pass through the filter 1231 for filtration, reducing the risk of liquid carrying impurities entering the flow chamber 13. In this embodiment, the filter 1231 is used to filter small particulate impurities in the fluid. When the fluid flows from the first sub-filter chamber 122, large particulate impurities are deposited in the first sub-filter chamber 122, but some small particulate impurities still exist in the fluid. Fluid carrying small particulate impurities enters the second sub-filter chamber 123 from the first sub-filter chamber 122, and then passes through the filter 1231 to screen out the small particulate impurities, leaving them in the filter 1231. The filtration by the filter 1231 allows the impurity-free fluid to enter the flow chamber 13, preventing impurities from settling in the flow chamber 13 and causing the oil suction mechanism 2 and water pumping mechanism 3 to pump away the impurities along with it, thus ensuring that the fluid in the flow chamber 13 is free of impurities.

[0023] Furthermore, an elbow 14 is provided on the upper end face of the housing 1, and the elbow 14 is connected to the first sub-filter chamber 122. In this embodiment, one end of the elbow 14 is inserted into the upper end face of the housing 1, and one end of the elbow 14 is connected to the first sub-filter chamber 122, while the other end of the elbow 14 can be connected to the external fluid that needs to be filtered. The elbow 14 has a corner. When external fluid enters the elbow 14, the fluid directly impacts the corner of the elbow 14. The elbow 14 absorbs part of the fluid's kinetic energy, reducing the fluid's kinetic energy and allowing the fluid to flow smoothly into the first sub-filter chamber 122. This prevents the fluid from impacting the bottom of the first sub-filter chamber 122, causing impurities that have settled in the first sub-filter chamber 122 to float back into the fluid. This would cause large particles of impurities to enter the second sub-filter chamber 123, which helps reduce the risk of debris entering the filter 1231 and clogging the filter 1231, preventing the fluid from passing through the filter 1231 and entering the flow chamber 13 from the second filter chamber 12.

[0024] Furthermore, the detection unit 31 includes multiple detection probes of varying lengths. The ends of these probes are located within the flow cavity 13, and the tips of the probes are mounted on the upper surface of the housing 1. In this embodiment, the detection probes are resistivity probes, meaning they determine whether the medium is water by measuring its conductivity. The detection unit 31 includes two detection probes of different lengths: a first detection probe 311 and a second detection probe 312. The first detection probe 311 is longer than the second detection probe 312. The end of the first detection probe 311 is located in the bottom region of the flow cavity 13, and the end of the second detection probe 312 is located in the middle region of the flow cavity 13. The first detection probe 311 is used to detect the lowest water level, and the second detection probe 312 is used to detect the highest water level, preventing excessive fluid overflow from the flow cavity 13 and facilitating real-time monitoring of the water level within the flow cavity 13.

[0025] It should be noted that the detection unit 31 also has a maximum oil level detector 34, and the end of the maximum oil level detector 34 is located in the flow chamber 13. The maximum oil level detector 34 is used to detect the oil level. When the oil level rises to the end of the maximum oil level detector 34, the buzzer built into the maximum oil level detector 34 will sound an alarm to remind the staff of the warning that the oil level is too high.

[0026] Furthermore, the pumping unit 32 includes a water pump 321, a suction pipe 322, and an outlet pipe 33. The input end of the water pump 321 is connected to one end of the suction pipe 322, and the output end of the water pump 321 is connected to one end of the outlet pipe 33. The other end of the suction pipe 322 extends to the bottom of the flow chamber 13, and the other end of the outlet pipe 33 is fixed to the upper surface of the housing 1. In this embodiment, the other end of the suction pipe 322 extends to the bottom of the flow chamber 13, and the end of the suction pipe 322 maintains a certain distance from the bottom of the flow chamber 13 to avoid the end of the suction pipe 322 abutting against the bottom, which would prevent the suction pipe 322 from forming an effective negative pressure zone, thus facilitating the rapid water intake of the suction pipe 322. Since the flow chamber 13 contains an oil-water mixture and the oil and water have different densities, the oil will float on the water surface. Therefore, the end of the suction pipe 322 extends to the bottom of the flow chamber 13 to ensure that the water pump 321 draws in water.

[0027] It should be noted that the pumping unit 32 includes a controller, which transmits data to the detection unit 31 via an electrical connection. The controller converts the data sent by the detection unit 31 into a corresponding pumping signal to control the pumping unit 32 to perform or stop pumping. When the detection unit 31 detects that the water level has risen to the end of the second detection probe 312, the detection unit 31 generates water level data and sends it to the controller in the pumping unit 32. The controller converts the water level data into a first pumping signal, and the pumping unit 32 starts working according to the first pumping signal to promptly remove the water from the flow chamber 13. When the detection unit 31 detects that the water level has dropped to the end of the first probe, the detection unit 31 generates water level data and sends it to the controller in the pumping unit 32. The controller converts the water level data into a second pumping signal, and the pumping unit stops working according to the second pumping signal, ceasing pumping.

[0028] Furthermore, the middle region of the outlet pipe 33 bends towards the bottom of the flow chamber 13 to form a U-shaped pipe. In this embodiment, the middle region of the outlet pipe 33 bends to form a U-shaped pipe, changing the straight flow channel into a curved flow channel and altering the direction of fluid movement. After the water pump 321 outputs water, some of the water remains at the bottom of the U-shaped pipe, achieving a liquid seal effect. This reduces the amount of external contaminants entering the water pump 321 along the U-shaped pipe, thus extending the service life of the water pump 321.

[0029] Furthermore, the oil suction mechanism 2 includes a gear pump 21, a drive assembly 22, and a transmission rod 23. One end of the transmission rod 23 is fixedly connected to the output end of the drive assembly 22, and the other end of the transmission rod 23 is connected to the gear pump 21. In this embodiment, the drive assembly 22 is installed on the upper surface of the housing 1, and the gear pump 21 is located in the flow chamber 13. The drive assembly 22 is connected based on the transmission rod 23, and the transmission rod 23 is driven by the drive assembly 22 to rotate. The rotation of the transmission rod 23 drives the gear pump 21 to work. When the gear pump 21 works, it sucks away the oil in the flow chamber 13 and promptly outputs the filtered oil to the next process.

[0030] It should be noted that the output end of the gear pump 21 is provided with an output pipe. One end of the output pipe is connected to the output end of the gear pump 21, and the other end of the output pipe is connected to the oil outlet provided on the upper surface of the housing 1, so that the oil pumped by the gear pump 21 can be output to the next process along the output pipe.

[0031] Furthermore, the gear pump 21 has a mounting cavity 210, in which a driving gear 211 and a driven gear 212 are disposed, and the driving gear 211 and the driven gear 212 mesh. The driving gear 211 is connected to the transmission rod 23, and the driving gear 211 is driven to rotate by the transmission rod 23. In this embodiment, the output end of the drive mechanism is connected to one end of the transmission rod 23. That is, when the drive mechanism outputs power, the transmission rod 23 is driven by the drive mechanism to rotate around the axis of the transmission rod 23. The transmission rod 23 drives the driving gear 211 to rotate, and the driving gear 211 meshes with the driven gear 212. When the driving gear 211 rotates, it drives the driven gear 212 to rotate, thereby driving the gear pump 21 to work. When the driving gear 211 rotates, it drives the driven gear 212 to rotate. The tooth grooves of the driving gear 211 and the driven gear 212 gradually disengage, forming a partial vacuum. Under the action of pressure difference, external fluid is drawn into the sealed chamber formed by the gear tooth groove and the inner wall of the pump body through the oil inlet of the gear pump 21. The driving gear 211 and the driven gear 212 continue to rotate in the flow chamber 13. The fluid in the sealed chamber is carried by the driving gear 211 and the driven gear 212 to the oil outlet of the gear pump 21, so that the fluid can flow from the oil inlet of the gear pump 21 to the oil outlet of the gear pump 21. This facilitates the gear pump 21 to transport the fluid in the flow chamber 13 to the next part, allowing the fluid to be output along a designated path.

[0032] Furthermore, an oil level gauge 4 is provided on the side wall of the housing 1, and the oil level gauge 4 communicates with the flow cavity 13. In this embodiment, the side wall of the housing 1 has two mounting holes, and the oil level gauge 4 is mounted on the side wall of the housing 1 based on the two mounting holes, and the interior of the oil level gauge 4 communicates with the flow cavity 13 based on the mounting holes. The oil level gauge 4 has a mounting cavity 210, and a scale is provided in the mounting cavity 210, which communicates with the flow cavity 13 based on the two mounting holes. Since the flow cavity 13 and the mounting cavity 210 are connected, that is, the fluid height in the flow cavity 13 is the same as the fluid height in the mounting cavity 210, the operator can observe the fluid level in the mounting cavity 210 covering the scale on the scale to understand the fluid level in the flow cavity 13, which is beneficial for the operator to intuitively understand the fluid level in the flow cavity 13.

[0033] In summary, this utility model incorporates a first baffle in the multi-functional thin oil pump, which divides the housing into a filtration chamber and a flow chamber. The fluid first passes through the filtration chamber, filtering out any impurities it carries. This staged chamber structure enables efficient impurity separation, reducing the risk of impurities entering the flow chamber and mitigating the risk of wear caused by impurities being drawn into the oil suction and water pumping mechanisms. Furthermore, this utility model includes an oil suction mechanism and a water pumping mechanism. The oil suction end of the oil suction mechanism is located in the middle region of the flow chamber, specifically in the oil layer of the oil-water mixture. The water suction end of the water pumping mechanism is located at the bottom of the flow chamber, specifically in the water layer of the oil-water mixture. This improves the purity of the liquid pumped by the oil suction and water pumping mechanisms.
