Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil purification technology, specifically to a construction oil filter with a flow regulating mechanism. Background Technology

[0002] Construction oil filters are oil purification devices widely used on construction sites for engineering machinery, power equipment, and mining machinery. Their basic working principle involves using negative pressure generated by an oil pump to draw the oil to be treated from the equipment's oil tank, forcing it through one or more filter elements with different filtration precisions. This removes impurities such as water, solid particles, and colloids from the oil. Finally, the cleaned oil is returned to the oil tank or a designated container, thereby extending the equipment's service life and ensuring the stable operation of the hydraulic system.

[0003] Traditional oil filters cause oil pressure changes when adjusting the flow rate, which impacts the preset valves and makes it difficult to maintain a stable flow rate. This requires frequent readjustment by operators, which is labor-intensive. Therefore, a construction oil filter with a flow rate adjustment mechanism is proposed to solve the problems mentioned above. Utility Model Content

[0004] To solve the above-mentioned technical problems, a construction oil filter with a flow regulation mechanism is provided. This technical solution solves the problem mentioned in the background art that the oil pressure changes generated during the flow regulation process of the oil filter will impact the preset valve, making it difficult to maintain a stable flow.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An oil filter for construction with a flow regulating mechanism includes an oil storage tank. A first oil pump, a primary filter chamber, and a fine filter chamber are fixedly installed on the upper surface of the oil storage tank. A diversion pipe is connected to the front end of the oil storage tank. A return pipe and an oil outlet pipe are connected to the front end of the diversion pipe. The end of the return pipe away from the diversion pipe is connected to the front end of the oil storage tank. A mounting plate is fixedly connected to the right end of the diversion pipe. A drive motor is fixedly installed on the front surface of the mounting plate. The output end of the drive motor passes through the right end of the diversion pipe and is fixedly connected to an adjusting plate. The left end of the adjusting plate is rotatably connected to the left inner wall of the diversion pipe. The outer surface of the adjusting plate abuts against the connection between the return pipe and the oil outlet pipe.

[0006] Preferably, four support legs are fixedly connected at the four corners of the lower surface of the oil storage tank.

[0007] Preferably, the input end of the first oil pump is connected to an oil inlet pipe.

[0008] Preferably, a first connecting pipe is connected between the output end of the first oil pump and the front end of the primary filter chamber, as well as between the rear end of the primary filter chamber and the rear end of the fine filter chamber.

[0009] Preferably, a second connecting pipe connects the front end of the fine filtration chamber to the upper surface of the oil storage tank.

[0010] Preferably, a second oil pump is provided on the diversion pipe.

[0011] Compared with the prior art, this utility model provides a construction oil filter with a flow regulating mechanism, which has the following beneficial effects: This invention utilizes an adjusting plate. The rotation of the adjusting plate alters the flow area of ​​the return pipe and the oil outlet pipe, resulting in a smooth adjustment process. During this process, some oil flows back to the storage tank through the return pipe, ensuring stable flow. This avoids the impact of sudden oil pressure changes on the adjusting components, stably maintaining the oil flow rate and meeting the stability requirements of construction equipment for oil flow.

[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0015] Reference Figures 1-4As shown, a construction oil filter with a flow regulating mechanism includes an oil storage tank 1. The oil storage tank 1 is used to store the oil to be filtered, the oil during the filtration process, and the oil after filtration, providing a stable oil storage space for the oil filtration process. During the filtration process, it continuously receives the filtered oil returned from the fine filtration chamber 5, as well as a portion of the oil returned from the return pipe 11. A first oil pump 3, a primary filter chamber 4, and a fine filtration chamber 5 are fixedly installed on the upper surface of the oil storage tank 1. The front end of the oil storage tank 1 is connected to... A second oil pump 10 is installed on the diversion pipe 9. The second oil pump 10 provides power for the flow of oil in the diversion pipe 9, drawing oil from the oil storage tank 1 and transporting it to the diversion pipe 9. The front end of the diversion pipe 9 is connected to a return pipe 11 and an oil outlet pipe 12. The end of the return pipe 11 away from the diversion pipe 9 is connected to the front end of the oil storage tank 1. The return pipe 11 is used to return a portion of the oil in the diversion pipe 9 to the oil storage tank 1. By changing the amount of return oil, in conjunction with the oil outlet pipe 12, the oil flow is achieved. The flow rate can be adjusted to allow the oil to circulate within the system when the oil output demand is low, preventing the oil from stagnating and deteriorating. A mounting plate 13 is fixedly connected to the right end of the distributor pipe 9. A drive motor 14 is fixedly mounted on the front surface of the mounting plate 13. The output end of the drive motor 14 passes through the right end of the distributor pipe 9 and is fixedly connected to an adjusting plate 15. The left end of the adjusting plate 15 is rotatably connected to the left inner wall of the distributor pipe 9. The outer surface of the adjusting plate 15 abuts against the connection between the return pipe 11 and the oil outlet pipe 12. The drive motor 14 serves as the power source for the rotation of the regulating plate 15. Through its output end, the regulating plate 15 rotates within the diversion pipe 9. When the regulating plate 15 rotates towards the return pipe 11, the flow area of ​​the return pipe 11 decreases, the flow area of ​​the oil outlet pipe 12 increases, and the oil output increases. Conversely, when the regulating plate 15 rotates towards the oil outlet pipe 12, the flow area of ​​the oil outlet pipe 12 decreases, the flow area of ​​the return pipe 11 increases, and some oil flows back to the oil storage tank 1, thus maintaining stable oil pressure.

[0016] Furthermore, four support legs 2 are fixedly connected to the four corners of the lower surface of the oil storage tank 1. The support legs 2 serve to support the oil storage tank 1 and the entire oil filter, keeping the oil storage tank 1 at a certain distance from the ground to avoid ground moisture and impurities affecting the oil storage tank 1, while ensuring the stability of the oil filter.

[0017] Furthermore, the input end of the first oil pump 3 is connected to the oil inlet pipe 6. The first oil pump 3 is used to extract the oil to be filtered from the oil storage tank 1 and transport it to the primary filter chamber 4 to provide power for the primary filtration of the oil and ensure that the oil can smoothly enter the filtration system.

[0018] Furthermore, a first connecting pipe 7 is connected between the output end of the first oil pump 3 and the front end of the primary filter chamber 4, as well as between the rear end of the primary filter chamber 4 and the rear end of the fine filter chamber 5. A second connecting pipe 8 is connected between the front end of the fine filter chamber 5 and the upper surface of the oil storage tank 1. The primary filter chamber 4 performs preliminary filtration on the oil delivered by the first oil pump 3, mainly removing larger impurities in the oil, reducing the filtration burden on the subsequent fine filter chamber 5, protecting the filter elements in the fine filter chamber 5, extending their service life, and laying the foundation for fine filtration of the oil. The fine filter chamber 5 performs fine filtration on the oil filtered by the primary filter chamber 4, removing smaller impurities, water, and some harmful substances such as colloids produced by oil oxidation, so that the purity and quality of the oil meet the requirements for construction and use.

[0019] Working Principle: In use, this invention first connects to an external power source and starts the first oil pump 3. The first oil pump 3 draws the oil to be filtered from the oil storage tank 1 through the oil inlet pipe 6, and then transports the oil to the primary filter chamber 4 for preliminary filtration via the first connecting pipe 7. The pre-filtered oil then enters the fine filter chamber 5 through the first connecting pipe 7 for fine filtration. The qualified oil after fine filtration flows back to the oil storage tank 1 through the second connecting pipe 8, completing the oil filtration cycle. When the construction equipment needs oil, the second oil pump 10 is started. The second oil pump 10 draws the qualified oil from the oil storage tank 1 and transports it to the diversion pipe 9. Based on the oil flow requirements of the construction equipment, the drive motor 14 is started, and the drive motor 14 drives the adjustment... The regulating plate 15 rotates within the diversion pipe 9, changing the flow area of ​​the return pipe 11 and the oil outlet pipe 12. After adjusting the oil flow rate of the oil outlet pipe 12 to meet the requirements of the construction equipment, the oil outlet pipe 12 is connected to the oil inlet of the construction equipment to supply oil to the equipment. During this process, some oil flows back to the oil storage tank 1 through the return pipe 11 to ensure stable flow. When construction is completed or oil supply is not required, the second oil pump 10 is turned off first, followed by the first oil pump 3. The connection between the oil outlet pipe 12 and the construction equipment is disconnected. The filter elements in the primary filter chamber 4 and the fine filter chamber 5 are cleaned regularly, and damaged parts are replaced. The condition of each pipeline, motor, oil pump, and other components is checked, and necessary maintenance is performed to prepare for the next use.
