Description

Technical Field

[0001] This utility model relates to the technical field of waste oil recycling and treatment equipment, and in particular to waste oil recycling and treatment equipment with multi-stage filtration and purification. Background Technology

[0002] With the rapid development of industrial production and transportation, the amount of waste oil generated is increasing day by day. Waste oil contains a large number of impurities, pollutants and harmful substances. If it is discharged directly without proper treatment, it will not only cause serious pollution to the environment, but also lead to the waste of resources.

[0003] In Chinese utility model patents, such as CN221267289U, a fuel oil waste oil-water separator is disclosed. Through the filter purification device frame, primary filter screen and secondary filter screen, small impurities in waste oil can be effectively filtered, improving the quality of finished oil and enhancing the product's reputation. At the same time, it can save production costs and avoid manufacturers spending a lot of time cleaning impurities in finished oil later, thus bringing better application prospects.

[0004] However, when the above technology is used, the waste oil enters the device through an open waste oil feed trough, and the waste oil gradually passes through multiple filter screens by gravity. Since the waste oil has a certain adhesion, its filtration efficiency is low. In view of this, this application proposes a multi-stage filtration and purification waste oil recycling and treatment device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-stage filtration and purification waste oil recycling and treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-stage filtration and purification waste oil recycling and treatment device includes a base, a filter box fixedly installed on the top surface of the base, multiple filter drawers slidably connected inside the filter box, a first handle fixedly installed on the outer side of each filter drawer, limiting mechanisms on both outer sides of the filter box to restrict the sliding position of the filter drawers, a sealing mechanism on the outer side of the filter box for sealing each filter drawer with the filter box, a first electric push rod fixedly installed on the top surface of the filter box, a first sealing rubber gasket slidably connected inside the filter box, and the bottom end of the first electric push rod fixedly connected to the top surface of the first sealing rubber gasket, a feed inlet fixedly connected to the outer side of the filter box, an air inlet pipe fixedly connected to the outer side of the filter box, a first solenoid valve installed on the air inlet pipe, and a U-shaped pipe fixedly connected to the bottom surface of the filter box, with second solenoid valves installed at both ends of the U-shaped pipe.

[0008] Preferably, the limiting mechanism includes two assembly plates, each assembly plate has a mounting plate slidably connected to its outer side, each mounting plate has multiple insert rods installed on one outer side, each filter drawer has two hanging ears symmetrically installed on its outer side, and each insert rod passes through the corresponding hanging ear. Each mounting plate and the corresponding assembly plate are connected by a limiting spring, and each limiting spring is sleeved on the outer side of the corresponding insert rod. Each mounting plate has a second handle fixedly installed on its outer side.

[0009] Preferably, the sealing mechanism includes an air injection box, which is fixedly installed on the outside of the base. The filter box has multiple openings on its outside, and each filter box is inserted into the corresponding opening. A first sealing rubber gasket is installed on the inner wall of each opening. Each first sealing rubber gasket is interconnected through a connecting pipe group, and the air injection box is connected to the connecting pipe group. An air injection mechanism is provided inside the air injection box.

[0010] Preferably, the gas injection mechanism includes a second electric push rod, which is fixedly installed on the outside of the gas injection box. A second sealing rubber pad is slidably connected inside the gas injection box, and the other end of the second electric push rod is fixedly connected to the outside of the second sealing rubber pad.

[0012] Preferably, the installation height of the air intake pipe is greater than the installation height of the top filter box.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model achieves pressurized filtration of waste oil through devices such as a first electric push rod, an air inlet pipe, and a first sealing rubber gasket. Unlike the prior art that relies solely on gravity to allow waste oil to pass through the filter screen, the first electric push rod pushes the first sealing rubber gasket to apply pressure to the waste oil, effectively overcoming the adhesion of the waste oil and causing it to quickly pass through the multi-stage filter box. This greatly improves the filtration efficiency of waste oil, reduces processing time, and enhances overall work efficiency.

[0015] 2. This utility model achieves rapid installation and disassembly of the filter box through limiting mechanism, sealing mechanism and other devices, and effectively avoids the problem of waste oil leakage during the treatment process. It not only improves the safety of equipment operation, but also prevents waste oil leakage from polluting the environment and ensures the cleanliness of the working environment.

[0016] 3. This utility model achieves efficient cleaning of equipment and smooth discharge of waste oil through devices such as U-shaped tubes. The two ends of the U-shaped tubes are connected to the water source and the waste oil recovery channel, which can perform backwashing operations. In conjunction with the first electric push rod driving the first sealing rubber pad to rise, the filter box is backwashed through the water source, which helps to improve the cleaning efficiency of the filter box.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] This utility model provides a technical solution: such as Figure 1-5As shown, the multi-stage filtration and purification waste oil recycling and treatment equipment includes a base 1, a filter box 2 is fixedly installed on the top surface of the base 1, and multiple filter drawers 6 are slidably connected inside the filter box 2. Each filter drawer 6 has a first handle 7 fixedly installed on its outer side. Limiting mechanisms are provided on both outer sides of the filter box 2, and the limiting mechanisms restrict the sliding position of the filter drawer 6 to ensure that the filter drawer 6 will not slide arbitrarily during operation and to ensure the stability of filtration.

[0025] The filter box 2 is equipped with a sealing mechanism on the outside, and the sealing mechanism is used to seal each filter box 6 with the filter box 2 to prevent waste oil leakage and improve the sealing performance and safety of the equipment.

[0026] A first electric push rod 3 is fixedly installed on the top surface of the filter box 2. A first sealing rubber gasket 12 is slidably connected inside the filter box 2, and the bottom end of the first electric push rod 3 is fixedly connected to the top surface of the first sealing rubber gasket 12. A feed inlet 13 is fixedly connected to the outside of the filter box 2, and an air inlet pipe 4 is fixedly connected to the outside of the filter box 2. A first solenoid valve 5 is installed on the air inlet pipe 4. A U-shaped pipe 9 is fixedly connected to the bottom surface of the filter box 2, and a second solenoid valve 10 is installed at both ends of the U-shaped pipe 9. Through the U-shaped pipe 9, the two ends of the U-shaped pipe 9 can be connected to a water source and a waste oil recovery channel, respectively. When it is necessary to clean the filter box 2, water can be injected into the filter box 2 through the U-shaped pipe 9. When water overflows the top filter box 6, its second solenoid valve 10 is closed, and the first electric push rod 3 is raised to backwash the filter box 6. After backwashing, the second solenoid valve 10 is opened, allowing the water to be discharged through the U-shaped pipe 9. Then, the filter box 6 is removed, and the cleaned impurities are poured out. When one end of the U-shaped pipe 9 is connected to the waste oil recovery channel, pressure can be applied to the waste oil in the filter box 2 to promote the filtration of waste oil and improve the efficiency of waste oil recovery. The air inlet pipe 4 allows air to be replenished when the first sealing rubber gasket 12 is raised, preventing the first sealing rubber gasket 12 from causing the waste oil to rise.

[0027] Furthermore, the limiting mechanism includes two assembly plates 8, each assembly plate 8 having a mounting plate 16 slidably connected to its outer side. Multiple insertion rods 18 are mounted on one outer side of each mounting plate 16. Two hanging ears 15 are symmetrically mounted on the outer side of each filter drawer 6, and each insertion rod 18 passes through the corresponding hanging ear 15. A limiting spring 19 is jointly installed between each mounting plate 16 and the corresponding assembly plate 8, and each limiting spring 19 is sleeved on the outer side of the corresponding insertion rod 18. A second handle 17 is fixedly mounted on the outer side of each mounting plate 16. By pulling the second handle 17, the mounting plate 16 is moved, causing the insertion rod 18 to disengage from the hanging ear 15, allowing for easy removal of the filter drawer 6 and replacement of the filter assembly. Releasing the second handle 17, under the action of the limiting spring 19, causes the insertion rod 18 to re-insert into the hanging ear 15, thus limiting and fixing the filter drawer 6.

[0028] Furthermore, the sealing mechanism includes an air injection box 14, which is fixedly installed on the outside of the base 1. The filter box 2 has multiple openings on its outside, and each filter drawer 6 is inserted into the corresponding opening. A first sealing rubber gasket 12 is installed on the inner wall of each opening. Each first sealing rubber gasket 12 is interconnected through a connecting pipe group 22, and the air injection box 14 is connected to the connecting pipe group 22. An air injection mechanism is provided inside the air injection box 14.

[0029] Furthermore, the gas injection mechanism includes a second electric push rod 20, which is fixedly installed on the outside of the gas injection box 14. A second sealing rubber gasket 21 is slidably connected inside the gas injection box 14, and the other end of the second electric push rod 20 is fixedly connected to the outside of the second sealing rubber gasket 21. By pushing the second sealing rubber gasket 21 through the second electric push rod 20, the gas in the gas injection box 14 can be injected into the first sealing rubber gasket 12 through the connecting pipe assembly 22, causing the first sealing rubber gasket 12 to expand and further enhance the sealing between the filter box 6 and the filter housing 2.

[0030] Furthermore, each filter box 6 is equipped with a sealing gasket 11 on its outer side, and each sealing gasket 11 abuts against the inner wall of the filter box 2 to prevent waste oil from flowing out through the gap between the filter box 6 and the filter box 2.

[0031] Furthermore, the installation height of the intake pipe 4 is greater than the installation height of the top filter box 6, which can prevent waste oil from entering the intake pipe 4 and ensure the normal ventilation function of the intake pipe 4.

[0032] This utility model provides a multi-stage filtration and purification waste oil recycling and treatment equipment. The specific working principle is as follows: Waste oil enters the filter box 2 through the inlet 13. Before the waste oil is injected, the equipment has completed the sealing treatment between the filter box 6 and the filter box 2 through the sealing mechanism. The second electric push rod 20 pushes the second sealing rubber gasket 21, and injects the gas in the gas injection box 14 into the first sealing rubber gasket 12 on the inner wall of the opening through the connecting pipe group 22, so that it expands and tightly fits the filter box 6. At the same time, the sealing gasket 11 on the outside of the filter box 6 also abuts against the inner wall of the filter box 2, so that the waste oil can only fall through the filter plate in the filter box 6.

[0033] Then the first electric push rod 3 is activated, pushing the first sealing rubber pad 12 downward to apply pressure to the waste oil and increase the filtration efficiency of the waste oil. Then the first solenoid valve 5 on the air inlet pipe 4 is opened, and the first electric push rod 3 drives the first sealing rubber pad 12 to rise. After that, the air inlet pipe 4 is closed, and the first sealing rubber pad 12 falls down again, applying pressure to the waste oil repeatedly.

[0034] Under pressure, the waste oil passes through each filter box 6 in sequence. Different filter boxes 6 can be equipped with filter components of different precision to gradually remove impurities, pollutants and harmful substances from the waste oil, thereby achieving multi-stage filtration and purification. The waste oil after multi-stage filtration and purification is discharged through the U-shaped pipe 9 fixed and connected to the bottom of the filter box 2.

[0035] When the filter box 2 needs cleaning, connect the water source and the waste oil recovery channel to both ends of the U-shaped pipe 9 respectively, and inject water into the filter box 2 so that the water source overflows the top filter drawer 6. Close the second solenoid valves 10 at both ends of the U-shaped pipe 9, and start the first electric push rod 3 to raise it, which drives the first sealing rubber gasket 12 to move upward, realizing the backwashing of the filter drawer 6 by the water source, washing off the impurities attached to the filter components. After the backwashing is completed, open the second solenoid valve 10 to discharge the cleaning wastewater through the U-shaped pipe 9.

[0036] After releasing the limiting mechanism of filter box 6, it can be removed, the cleaned impurities can be poured out, and the equipment cleaning work is completed.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
