Description

Technical Field

[0001] The utility model relates to the technical field of waste oil purification, in particular to a purification device for waste oil treatment. Background Art

[0002] With the rapid development of industry and the catering industry, the amount of waste oil generated is increasing. Improper disposal of waste oil can cause serious environmental pollution, endangering human health and ecological balance. In order to protect the environment and recycle and reuse resources, waste oil generally needs to be purified before it can be reused.

[0003] According to a search, Chinese patent document publication number CN221244241U discloses a hazardous waste oil and water treatment and purification device. By starting the motor, the motor's output drives the rotating shaft, causing the rotating block to rotate accordingly. The impactor is provided, and the impactor, under the action of the rotating body, can continuously move back and forth laterally. This allows the striking plate to intermittently impact the side of the filter screen, causing the filter screen to vibrate. The vibration accelerates the flow of the hazardous waste oil and water, thereby improving the efficiency of the hazardous waste oil and water filtration treatment, and the hazardous waste oil and water flows into the oil outlet pipe in a timely manner and is discharged, completing the hazardous waste oil and water purification process.

[0004] However, in actual use, the above-mentioned purification device increases the fluidity of waste oil by causing vibrations to impact the filter. This not only increases noise and affects the on-site environment, but also only filters large impurities through the filter, resulting in unsatisfactory filtration effects. Therefore, further innovation and improvement are needed. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the utility model provides a purification equipment for waste oil treatment, which has the advantages of being able to perform multi-stage filtration and purification of waste oil, thereby achieving better waste oil purification effect, and solves the above technical problems.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waste oil purification device, comprising a box body, wherein two polished rods are fixedly connected to the inner wall of the box body, a pressure plate, a filter plate, a filter frame and a tail plate are arranged between the two polished rods, industrial filter paper is clamped between the filter plate and the filter frame, and sliders are fixedly connected on both sides of the pressure plate, filter plate, filter frame and tail plate, one side of the slider is fixedly connected to a pin rod, the outer surface of the pin rod is slidably connected to a connecting piece, the center of the outer surface of the pressure plate is rotatably connected to the adjusting rod, the outer surface of the tail plate is fixedly connected to an oil inlet pipe and an oil outlet pipe, one end of the oil inlet pipe is connected to a pumping pipe, one end of the pumping pipe is connected to an oil pump, the suction end of the oil pump is connected to an oil extraction pipe, one end of the oil extraction pipe is connected to a primary filter, and an oil inlet valve is installed on the outer surface of the primary filter.

[0009] Preferably, a filter element is provided inside the primary filter, and the primary filter is connected to the outer wall of the box through a clamp.

[0010] Through the above technical solution, the oil pipe for waste oil is connected to the oil inlet valve. After the oil inlet valve is opened, the oil pump is started to generate negative pressure in the oil extraction pipe, and then negative pressure is generated inside the primary filter. In this way, the waste oil enters the interior of the primary filter through the oil inlet valve. Since a filter element is provided inside the primary filter, the waste oil will pass through the filter element after entering and filter out larger impurities, thus realizing primary treatment of the waste oil.

[0011] Preferably, the bottom of the primary filter is connected to an oil extraction pipe, and the output end of the oil pump is connected to a pumping pipe.

[0012] The filter press of the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter screen, and the filter press is moved along the filter

[0013] Preferably, a pressure gauge is installed between the pumping pipe and the oil inlet pipe, and two through holes are provided through the outer surfaces of the filter plate and the filter frame.

[0014] Through the above technical solution, by setting a pressure gauge, the pressure during oil inlet can be observed at any time. If the pressure during oil inlet increases significantly, it is judged that the industrial filter paper is seriously clogged. By rotating the handle in the opposite direction to drive the adjusting rod to rotate counterclockwise, the pressure plate can be driven to move in the direction of the adjusting rod. In this way, a gap is generated between the filter plate and the filter frame, so that the industrial filter paper can be pulled out and then replaced with a new industrial filter paper, thereby restoring the filtering effect of the waste oil.

[0015] Preferably, a sliding groove is provided through the outer surface of the connecting piece, a connecting piece is slidably connected between two adjacent pin rods, and a rotating handle is connected to the end of the adjusting rod away from the pressure plate.

[0016] Through the above technical solution, during the process of replacing industrial filter paper, the adjusting rod is rotated in the opposite direction to drive the pressure plate to move. At this time, the pressure plate drives the pin rod connected to it to move, the pin rod drives the connecting piece, and the connecting piece drives another pin rod connected to the filter plate. In this way, multiple groups of filter plates and filter frames can be unfolded one by one, which avoids the need to separate the filter plates and filter frames one by one, thereby improving the efficiency of separating the filter plates and filter frames, and thus improving the efficiency of replacing industrial filter paper.

[0017] Preferably, one end of the oil outlet pipe is connected to an oil-water separator, and an oil drain valve is installed on the outer surface of the oil-water separator.

[0018] Through the above technical solution, if the original waste oil contains water, the oil after multi-stage filtration can be discharged from the oil outlet pipe and then enter the oil-water separator for oil-water separation. If the original waste oil does not contain water, this step is not necessary. The overall structure can selectively filter out the water in the waterproof waste oil, making the waste oil purification more comprehensive.

[0019] Preferably, a reflux valve is installed at the bottom of the box body, the bottom end of the reflux valve is connected to an oil return pipe, and one end of the oil return pipe is connected to the outer surface of the primary filter.

[0020] Through the above technical solution, when the waste oil undergoes multi-stage filtration, some oil will precipitate from between the filter plate, industrial filter paper and filter frame, and then settle inside the box. If the level of the precipitated oil is too high, it will affect the filtration effect of the waste oil. Therefore, by opening the reflux valve, the oil in the box enters the return oil pipe, and then enters the primary filter under the action of the oil pump, and then undergoes multi-stage filtration again.

[0021] Compared with the prior art, the present invention provides a waste oil purification device with the following beneficial effects:

[0022] 1. The utility model connects the waste oil pipeline to the oil inlet valve. Under the transportation of the oil pump, the waste oil can first pass through the primary filter to filter out larger impurities, and then transport the waste oil to the sandwich between multiple filter plates, filter frames and industrial filter papers. The multiple industrial filter papers filter out fine impurities step by step. The overall structure enables the waste oil to undergo multi-stage filtration treatment, thereby achieving a replacement purification effect.

[0023] 2. The utility model drives the pressure plate to move by rotating the adjusting rod in the opposite direction. At this time, the pressure plate drives the pin rod connected to it to move, the pin rod drives the connecting piece, and the connecting piece drives another pin rod connected to the filter plate. In this way, multiple groups of filter plates and filter frames can be unfolded one by one, which avoids the need to separate the filter plates and filter frames one by one, thereby improving the efficiency of separating the filter plates and filter frames, and further improving the efficiency of replacing industrial filter paper.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1-4, a purification equipment for waste oil treatment, including a box body 1, two polished rods 2 are fixedly connected to the inner wall of the box body 1, a pressure plate 3, a filter plate 4, a filter frame 5 and a tail plate 6 are arranged between the two polished rods 2, and industrial filter paper 24 is clamped between the filter plate 4 and the filter frame 5, and sliders 7 are fixedly connected on both sides of the pressure plate 3, the filter plate 4, the filter frame 5 and the tail plate 6, one side of the slider 7 is fixedly connected to the pin rod 8, the outer surface of the pin rod 8 is slidably connected with a connecting piece 9, the center of the outer surface of the pressure plate 3 is rotated to connect the adjusting rod 10, and the outer surface of the tail plate 6 is fixedly connected to an oil inlet pipe 11 and an oil outlet pipe 12, one end of the oil inlet pipe 11 is connected to a pumping pipe 13, one end of the pumping pipe 13 is connected to an oil pump 14, the suction end of the oil pump 14 is connected to an oil extraction pipe 15, one end of the oil extraction pipe 15 is connected to a primary filter 16, and an oil inlet valve 17 is installed on the outer surface of the primary filter 16.

[0031] Specifically, a filter element is disposed within the primary filter 16, and the primary filter 16 is connected to the outer wall of the housing 1 via a clamp. This advantageously allows the waste oil pipe to be connected to the oil inlet valve 17. After opening the oil inlet valve 17, the oil pump 14 is activated to generate negative pressure within the oil extraction pipe 15, which in turn generates negative pressure within the primary filter 16. This allows the waste oil to enter the primary filter 16 through the oil inlet valve 17. Since the filter element is disposed within the primary filter 16, the waste oil passes through the filter element upon entry, filtering out larger impurities, thereby achieving primary treatment of the waste oil.

[0032] Specifically, the bottom of the primary filter 16 is connected to the oil extraction pipe 15, and the output end of the oil pump 14 is connected to the pumping pipe 13. The advantage is that after the waste oil passes through the primary filter 16 to filter out larger impurities, the oil pump 14 continuously pumps the waste oil through the oil extraction pipe 15 to deliver the primary filtered waste oil to the pumping pipe 13, and then into the oil inlet pipe 11; in the process of filtering and purifying the waste oil, an industrial filter paper 24 is clamped between the filter plate 4 and the filter frame 5, and the filter plate 4, the filter frame 5 and the industrial filter paper 24 are provided in multiple groups. By rotating the adjustment rod 10 to drive the pressure plate 3 to move, the multiple groups can be guided by the two polished rods 2. The filter plate 4, the filter frame 5 and the industrial filter paper 24 are tightly fitted together. Since two through holes are provided on the outer surfaces of the filter plate 4, the filter frame 5 and the industrial filter paper 24, the two through holes correspond to the oil inlet pipe 11 and the oil outlet pipe 12 respectively. In this way, when the waste oil enters the oil inlet pipe 11, it will gradually penetrate into each filter plate 4, and then pass through multiple industrial filter papers 24 to filter out fine impurities step by step. Finally, the purified oil can be discharged from the oil outlet pipe 12. The overall structure allows the waste oil to undergo multi-stage filtration, and the filtering and purification effect is good.

[0033] Specifically, a pressure gauge 18 is installed between the pumping pipe 13 and the oil inlet pipe 11. Two through-holes are provided through the outer surfaces of the filter plate 4 and the filter frame 5. Advantageously, the pressure gauge 18 allows for constant monitoring of the oil inlet pressure. If the inlet pressure increases significantly, it is determined that the industrial filter paper 24 is severely clogged. By rotating the handle 19 in the opposite direction, the adjusting rod 10 rotates counterclockwise, which in turn moves the pressure plate 3 toward the adjusting rod 10. This creates a gap between the filter plate 4 and the filter frame 5, allowing the industrial filter paper 24 to be removed and subsequently replaced with a new one, thus restoring the waste oil filtration effect.

[0034] Specifically, a chute is provided through the outer surface of the connecting piece 9, and a connecting piece 9 is slidably connected between two adjacent pin rods 8. The end of the adjusting rod 10 away from the pressure plate 3 is connected to a rotating handle 19. The advantage is that during the process of replacing the industrial filter paper 24, the adjusting rod 10 is rotated in the opposite direction to drive the pressure plate 3 to move. At this time, the pressure plate 3 drives the pin rod 8 connected to it to move, and the pin rod 8 drives the connecting piece 9, and the connecting piece 9 drives another pin rod 8 connected to the filter plate 4. Such transmission can cause multiple groups of filter plates 4 and filter frames 5 to be deployed one by one, thus avoiding the need to separate the filter plates 4 and filter frames 5 one by one, thereby improving the efficiency of separating the filter plates 4 and filter frames 5, and further improving the efficiency of replacing the industrial filter paper 24.

[0035] Specifically, one end of the oil outlet pipe 12 is connected to an oil-water separator 20, and an oil drain valve 21 is mounted on the outer surface of the oil-water separator 20. The advantage is that if the original waste oil contains water, the oil, after multi-stage filtration, can be discharged from the oil outlet pipe 12 and then enter the oil-water separator 20 for oil-water separation. If the original waste oil does not contain water, this step is not required. The overall structure can selectively filter out water from the waterproof waste oil, resulting in more comprehensive waste oil purification.

[0036] Specifically, a return valve 22 is installed at the bottom of the housing 1. The bottom end of the return valve 22 is connected to an oil return pipe 23, one end of which is connected to the outer surface of the primary filter 16. The advantage is that during the multi-stage filtration process, some oil in the waste oil will precipitate from between the filter plate 4, the industrial filter paper 24, and the filter frame 5, and then settle inside the housing 1. If the level of the settled oil is too high, it will affect the filtration effect of the waste oil. Therefore, by opening the return valve 22, the oil in the housing 1 enters the oil return pipe 23, and then enters the primary filter 16 under the action of the oil pump 14, and then undergoes multi-stage filtration again.

[0037] When in use, first connect the waste oil pipeline to the oil inlet valve 17, and start the oil pump 14 to generate negative pressure in the oil extraction pipe 15, thereby generating negative pressure inside the primary filter 16. In this way, the waste oil enters the interior of the primary filter 16 through the oil inlet valve 17, and then passes through the filter element to filter out larger impurities and complete the primary treatment. Under the continuous suction action of the oil pump 14 and the oil extraction pipe 15, the waste oil after primary filtration can be sent to the pumping pipe 13, and then enter the oil inlet pipe 11, and then gradually penetrate into each filter plate 4. Then, fine impurities are filtered out step by step through multiple industrial filter papers 24, and finally the purified oil can be discharged from the oil outlet pipe 12. If the original waste oil contains water, the oil outlet pipe 12 is connected to the oil-water separator 20, and the water is filtered out through the oil-water separator 20, and the purified oil is discharged by opening the oil drain valve 21; when the oil level inside the box 1 is too high, the return valve 22 can be opened to allow the oil in the box 1 to enter the return oil pipe 23, and then enter the primary filter 16 under the action of the oil pump 14, and then undergo multi-stage filtration again.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
