Description

Technical Field

[0001] This invention relates to the field of oil pumping unit purification technology, specifically a purification device for a mobile oil pumping unit reducer. Background Technology

[0002] Pumping units are key equipment in oilfield production. In harsh field conditions, gearbox oil leakage and rapid oil deterioration are major problems affecting their operation. This not only impacts normal equipment operation and production output but also increases daily management and maintenance workload. Addressing gearbox oil leakage and deterioration is a crucial problem we must solve. The gearbox is a vital component of the pumping unit system. Its function is to reduce the high-speed rotation of the electric motor to a low-speed rotation of the output shaft via a three-shaft, two-pole gear transmission, thereby driving the entire pumping unit system. The gearbox uses oil bath lubrication, with gears immersed in oil and bearings lubricated by splash lubrication. Its characteristics include high load capacity and suitability for long-term field operation.

[0003] The oil inside the pumping unit reducer often contains a certain amount of water. If this water is not removed in time, it will affect the normal operation of the reducer. In cold operating environments, the liquid may solidify or increase in viscosity due to low temperature, affecting the normal operation of filtration, purification, and water evaporation. The oil also contains a large number of tiny particles and impurities. Therefore, it is necessary to design corresponding technical solutions to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a mobile oil pump reducer purification device, which solves the technical problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a mobile oil pump reducer purification device, comprising a device body, a separator, a circulating pump, a filter, a diversion pipe, a circulating transfer pipe and a base, wherein a control box is provided at the outer end of the device body, the base is a ladder structure and a fixed horizontal plate is fixedly provided at the rear end, and the fixed horizontal plate is fixedly provided at the inner end of the device body. The separators are fixedly distributed on the upper end of the base and are connected by a connecting pipe at the middle of them. Evaporation tubes are distributed through the upper edge of the separators. A motor is connected to the side of the circulating pump, a control and detection system is connected to the right end of the circulating pump, a water pumping pipe is provided at the outer end of the circulating pump, a water pumping pipe is provided at the inner end of the circulating pump, and the water pumping pipe is connected to the upper part of the separator side on the left end. A suction tube is connected between the front end of the filter and the separator; The circulation adapter is connected between the filter and the diversion pipe, and a return pipe is connected between the front end of the diversion pipe and the separator.

[0006] Preferably, a drain pipe is fixedly connected to the lower rear end of the separator, and a solenoid valve is connected to the side end of the drain pipe; a heat dissipation fin is installed in the middle of the upper end of the separator; the solenoid valve is used to electrically control the drain pipe to drain water, and the heat dissipation fin is used to accelerate the heat dissipation and evaporation of internal moisture.

[0007] Preferably, the upper end of the base is provided with a heating base, and heating ring tubes are electrically connected and distributed above the heating base. The heating ring tubes are connected around the lower end of the separator. The front end of the heating base is electrically connected to a control panel, which is located in the middle of the front end of the base. The control panel is used to intelligently and precisely control the heating base to supply power to multiple sets of heating ring tubes. The heating ring tubes are used to uniformly heat the separator to achieve rapid oil-water separation.

[0008] Preferably, a support plate is fixedly provided at the bottom of the circulating pump, and a support is fixedly provided at the bottom of the motor. Both the support plate and the support are installed on the lower inner side of the equipment body, and a power control box is electrically connected to the side of the motor. The support plate and the support are used to securely install the circulating pump and the motor upwards. The motor is used to drive and control the circulating pump, and the circulating pump is used to control the pumping of liquid.

[0009] Preferably, a liquid level sensor is installed at the upper front end of the separator, and a power supply link is connected between the liquid level sensors. A power adapter is electrically connected between the liquid level sensor located at the left end and the power control box. The liquid level sensor is used to monitor the liquid level at the upper end of the separator in real time to prevent the liquid poured into the separator from overflowing the evaporator tube due to excessive liquid level. The power supply link and the power adapter are connected to the power control box to link the circulation pump, so as to stop the liquid inlet in time.

[0010] Preferably, the filter has an inner filter outer cylinder, which is a cylindrical structure and has a positioning ring plate fixed at its outer end. The outer end of the positioning ring plate is fixed with a handle two. The outer side wall of the positioning ring plate is connected by threaded locking bolts. Multiple locking bolts are used to securely seal the positioning ring plate to one end of the filter. The cylindrical filter outer cylinder is used to fully filter the liquid from the suction tube. The handle two is convenient for hand-held disassembly and assembly, and facilitates subsequent maintenance and replacement of the filter outer cylinder.

[0011] Preferably, the outer filter cylinder has an inner filter cylinder inside, and an end cap is fixedly provided at the outer end of the inner filter cylinder. The end cap is threadedly installed at one end of the filter, and a handle is fixedly provided at the outer end of the end cap. The end cap is used to directly install to one end of the filter via threads, ensuring the sealing of the filtration system and preventing liquid leakage. The diameter of the inner filter cylinder is smaller than the diameter of the outer filter cylinder, and the inner filter cylinder is located inside the outer filter cylinder. The double-layered structure of the inner and outer cylinders further achieves high-efficiency filtration and purification.

[0012] Preferably, the lower end of the suction tube passes through the separator and is connected to an extension suction tube. The lower end of the extension suction tube has an oblique opening, and the side of the extension suction tube has through holes distributed at equal intervals.

[0013] Preferably, an inlet pipe and an outlet pipe are respectively installed in the middle of the circulation transfer pipe, and a circulation pump is connected in the middle of the inlet pipe and the outlet pipe. A support is fixed between the lower end of the circulation pump and the diversion pipe. The support is used to stably support the circulation pump above the diversion pipe. The circulation pump is used to control the liquid to enter from the inlet pipe and then exit from the outlet pipe to realize the circulation of liquid.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the multiple sets of separators connected to the inner end of the circulating pump facilitate uniform and effective oil-water separation; the distributed evaporation tubes connected through the upper edge of the separator can efficiently and quickly evaporate the water inside the separator, thereby improving the purification efficiency. A circulation system connected to the upper and lower ends of the separator, including a suction pipe, filter, circulation adapter pipe, diversion pipe, and return pipe, forms a circulation loop for oil and water liquids to improve the filtration and purification effect. The double-layer filtration structure of the filter's outer and inner cylinders greatly enhances the filtration effect. The liquid first undergoes preliminary filtration in the outer cylinder to remove larger impurities, and then enters the inner cylinder for finer filtration, effectively removing tiny particles and impurities from the liquid and improving the purification quality. The equally spaced through holes on the side of the extended suction pipe greatly improve the uniformity of liquid suction, allowing the liquid to enter the filtration system more fully for filtration and purification. By installing a heating ring pipe in the lower half of the separator, the separator is heated evenly, keeping the liquid inside the separator at a suitable temperature and improving the oil-water separation speed.

[0023] Further improvements include an outer filter cylinder 63 inside the filter 6, which is a cylindrical structure and has a positioning ring plate 631 fixed at its outer end. A handle 632 is fixed at the outer end of the positioning ring plate 631, and locking bolts 633 are distributed on the outer side wall of the positioning ring plate 631 through threaded connections.

[0025] In a further improvement, the lower end of the suction tube 61 passes through the separator 2 and is connected to an extension suction tube 611.

[0026] Specifically, an inlet pipe 811 and an outlet pipe 812 are installed in the middle of the circulation transfer pipe 8, and a circulation pump 81 is connected in the middle of the inlet pipe 811 and the outlet pipe 812. A support seat 82 is fixedly provided between the lower end of the circulation pump 81 and the diversion pipe 7.

[0027] Working principle: The oil inside the pump reducer is drawn out through the water pipe 51 and connected to the hose, and then pumped to the separator 2 through the pump pipe 52. Multiple separators 2 are connected through the connecting pipe 20 to keep the oil inside them at the same level. The level sensor 4 monitors the oil inside the separator 2 in real time. When the oil level is reached, power is supplied to the power control box 55 through the power linkage 41 and the power adapter 42. The motor 56 drives and controls the circulation pump 5 to stop feeding liquid. Start the circulation pump 81 of the circulation transfer pipe 8, and the liquid enters and exits through the inlet pipe 811 and the outlet pipe 812; The oil is drawn out through the extended suction tube 611 at the lower end of the suction tube 61, and the oil inside the separator 2 is evenly drawn out through multiple through holes 6111. After entering the filter 6, it passes through the double-layer filter outer cylinder 63 and filter inner cylinder 62. The double-layer filter structure greatly improves the filtration effect. The liquid first passes through the preliminary filtration of the filter outer cylinder 63 to remove larger impurities, and then enters the filter inner cylinder 62 for more fine filtration, effectively removing small particles and impurities in the liquid and improving the purification quality. Then, it flows back to the inside of the separator 2 through multiple sets of return pipes 71 at the inner end of the diversion pipe 7; At the same time, the heating base 3 is activated by the control panel 32, which causes multiple heating rings 31 to heat the separator 2, so that the separator 2 can quickly achieve oil-water separation. The water evaporates through the heat dissipation fins 22, and then the water inside the separator 2 is quickly evaporated through the evaporation pipe 23, which improves the purification efficiency. Finally, start the solenoid valve 211 to open the drain pipe 21 and drain the oil.
