Description

Technical Field

[0001] This utility model relates to the field of oil filters, and in particular to an automatic settling oil filter. Background Technology

[0002] A certain amount of waste oil is generated during the production process. Direct discharge not only pollutes the environment but also wastes resources. Oil filters can treat waste oil by separating oil and water, allowing for the regeneration and recycling of the waste oil, reducing environmental pollution, and lowering production costs. Existing oil filtration equipment is mostly ultrasonic demulsifiers, which use high-frequency vibration to separate oil and water. However, using ultrasonic demulsifiers requires opening the filter housing, and operators at the top may experience oil leaks onto the outside or ground, posing a safety risk. Operating at the top also involves the risk of falls due to working at height. Furthermore, opening the housing causes oil vapors that may harm workers, and the oil mist can spread pollution. Additionally, the separated water contains small amounts of oil impurities, posing an environmental risk if discharged directly. Therefore, we propose an automatic sedimentation oil filter to solve these problems. Utility Model Content

[0003] This utility model provides an automatic sedimentation oil filter, which solves the problems of using an ultrasonic demulsifier requiring opening the filter tank, which makes it easy for workers to operate the equipment from the top of the tank, causing oil leakage, inconvenience to workers, safety risks, and potential harm to workers from oil fumes; and the presence of a small amount of oil in the separated water.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an automatic settling oil filter, including an oil filter, a buffer baffle on the oil filter, multiple flow plates on the oil filter, the multiple flow plates are arranged alternately, and a flow port is formed between the flow plates and the inner wall of the oil filter. A first pump body and a second pump body are provided at the other end of the oil filter, and an oil return mechanism is provided on the oil collection tank. The first pump body is connected to the oil collection tank.

[0005] In a preferred embodiment, one end of the oil filter is equipped with a partition plate, which divides the front end of the oil filter into a buffer zone and a flow zone. A buffer baffle is installed in the buffer zone, and an inlet pump is provided on one side of the buffer zone.

[0006] In the preferred embodiment, the inlet pump includes an inlet pump pipe that penetrates the oil filter and extends into the buffer zone. The partition plate has a notch, and the buffer baffle has an inclined structure.

[0007] In the preferred embodiment, the oil filter is provided with two liquid outlets, one of which is connected to the first pump body and the other of which is connected to the second pump body. The second pump body is provided with a connected return oil tank on one side.

[0008] In a preferred embodiment, one end of the oil filter is equipped with a pull-wire sensor, and the other end of the pull-wire sensor is equipped with a float ball. The density of the float ball is greater than the density of oil and less than the density of water.

[0009] In a preferred embodiment, one end of the flow plate abuts against the inner wall of the oil filter, and the other end of the flow plate forms a flow opening with the inner wall on the other side of the oil filter. The length of the flow plate is less than the width of the internal cavity of the oil filter.

[0010] In a preferred embodiment, the oil return mechanism includes a housing with two mounting slots and a rotating oil suction roller mounted on each slot. Multiple cylinders are mounted on the bottom of the housing and installed on the oil collection tank. A scraper is provided on one side of the oil suction roller.

[0011] In the preferred embodiment, the scraper is installed on the mounting groove, the oil return mechanism includes a first motor, a main bevel gear is provided on the output shaft of the first motor, a meshing driven bevel gear is provided on the main bevel gear, a rotating shaft is provided on the oil suction roller, the driven bevel gear is installed on the rotating shaft, and a third pump body is provided on the housing.

[0012] The beneficial effects of this invention are as follows: The buffer baffle slows down the flow rate of the inlet pump, allowing the oil-water mixture to flow slowly from one end of the oil filter to the other. When the oil-water mixture reaches the first few flow plates, it is blocked, further reducing its flow rate and allowing it to flow at a slower speed, effectively accelerating the stratification of the oil-water mixture. The multiple flow plates are arranged in a staggered manner, resulting in multiple flow outlets that are also staggered. The inner wall of the oil filter has a long travel distance, and the staggered arrangement of the multiple flow plates on the inner wall greatly increases the travel distance of the oil-water mixture from one end of the filter to the other, increasing the flow time and travel distance, thus allowing for sufficient oil and water stratification.

[0013] When the oil-water mixture flows to the end of the oil filter, the oil-water separation is completed. The first pump body is driven to collect the water into the oil collection tank. When the float ball of the pull-wire sensor touches the ground of the oil filter, the pull-wire sensor outputs a signal and drives the second pump body to collect the oil into the return oil tank, so that the oil and water are separated for the first time.

[0014] After the oil collection tank finishes collecting the oil, the cylinder is driven to raise and lower the tank relative to the oil collection tank. The first motor is then driven to make the two oil suction rollers roll and suck up the oil. The scraper hangs the oil sucked up by the oil suction rollers into the tank. The third pump is then driven to transport the sucked oil to the buffer zone for a second oil-water separation.

[0015] The overall structure avoids the need to open the top of the oil filter when using an ultrasonic demulsifier, thus preventing workers from operating the equipment from above and causing oil leaks. It also prevents potential hazards to workers operating the equipment from oil fumes. The oil return mechanism can discharge a small amount of oil from the separated water for a second oil-water separation, preventing direct discharge of oil-containing water and avoiding environmental pollution. This design has significant potential for widespread adoption. Attached Figure Description

[0024] Example 1:

[0025] like Figure 1-6An automatic settling oil filter includes an oil filter 1, a buffer baffle 4, and multiple flow plates 5 arranged in an alternating pattern. A flow port 501 is formed between the flow plates 5 and the inner wall of the oil filter 1. A first pump body 9 and a second pump body 10 are located at the other end of the oil filter 1. An oil return mechanism 7 is provided on an oil collection tank 6, and the first pump body 9 is connected to the oil collection tank 6. This structure drives the inlet pump 2, causing the oil-water mixture to impact the buffer baffle 4 through the inlet pump pipe 201. The buffer baffle 4 slows down the flow rate of the inlet pump 2, allowing the oil-water mixture to flow slowly from one end of the oil filter 1 to the other. When the oil-water mixture reaches the first few flow plates 5, the flow rate is further reduced by the obstruction of the oil-water mixture, allowing it to flow at a slower speed and effectively accelerating the stratification of the oil-water mixture. Multiple flow plates 5 are arranged in an alternating manner so that multiple flow ports 501 are arranged in an alternating manner. The inner wall of the oil filter 1 has a long stroke. The multiple flow plates 5 are arranged in an alternating manner on the inner wall of the oil filter 1, which greatly increases the stroke of the oil-water mixture from one end of the oil filter 1 to the other end of the oil filter 1, and increases the flow time and flow stroke of the oil-water mixture, so that the oil-water mixture can be sufficiently separated into oil and water.

[0026] When the oil-water mixture flows to the tail end of the oil filter 1, the oil-water separation is completed. The first pump body 9 is driven first to collect the water into the oil collection tank 6. When the float 801 of the pull wire sensor 8 contacts the ground of the oil filter 1, the pull wire sensor 8 outputs a signal and drives the second pump body 10 to collect the oil into the return oil tank, so that the oil and water are separated for the first time.

[0027] After the oil collection tank 6 has finished collecting, the cylinder 708 is driven to raise and lower the tank body 701 relative to the oil collection tank 6, and the first motor 704 is driven to make the two oil suction rollers 703 roll to suck up the oil. The scraper 705 hangs the oil sucked up by the oil suction rollers 703 into the tank body 701, and the third pump body is driven to transport the sucked oil to the buffer zone 101 for a second oil-water separation.

[0028] The overall structure avoids the need to open the top of the oil filter 1 when using an ultrasonic demulsifier, thus preventing personnel from operating the equipment from the top and causing oil leakage. It also prevents oil fumes from potentially harming personnel operating the equipment from above. The oil return mechanism 7 can discharge a small amount of oil from the separated water for a second oil-water separation, preventing direct discharge of oil-containing water and thus avoiding environmental pollution.

[0029] In a preferred embodiment, a partition plate 3 is provided at one end of the oil filter 1, which divides the front end of the oil filter 1 into a buffer zone 101 and a flow zone 102. A buffer baffle 4 is installed in the buffer zone 101, and an inlet pump 2 is provided on one side of the buffer zone 101. With this structure, both outlets 103 are located at the bottom of the oil filter 1.

[0030] In a preferred embodiment, the inlet pump 2 includes an inlet pump pipe 201 that penetrates the oil filter 1 and extends into the buffer zone 101. The partition plate 3 has a notch 301, and the buffer baffle 4 has an inclined structure. This structure drives the inlet pump 2, causing the oil-water mixture to pass through the inlet pump pipe 201 and impact the buffer baffle 4. The buffer baffle 4 slows down the flow rate of the inlet pump 2, allowing the oil-water mixture to slowly flow from one end of the oil filter 1 to the other.

[0031] In a preferred embodiment, the oil filter 1 is provided with two liquid outlets 103. One liquid outlet 103 is connected to the first pump body 9, and the other liquid outlet 103 is connected to the second pump body 10. The second pump body 10 is provided with a connected return oil tank on one side.

[0032] In a preferred embodiment, one end of the oil filter 1 is equipped with a pull-wire sensor 8, and one end of the pull-wire sensor 8 is equipped with a float 801. The density of the float 801 is greater than the density of oil and less than the density of water. With this structure, when the oil-water mixture flows to the tail end of the oil filter 1, oil-water stratification is completed. The first pump body 9 is driven first to collect the water into the oil collection tank 6. When the float 801 of the pull-wire sensor 8 contacts the ground of the oil filter 1, the pull-wire sensor 8 outputs a signal, stops the operation of the first pump body 9, and drives the second pump body 10 to collect the oil into the return oil tank, thus achieving the first separation of oil and water.

[0033] In a preferred embodiment, one end of the flow plate 5 abuts against the inner wall of the oil filter 1, and the other end of the flow plate 5 forms a flow port 501 between it and the inner wall on the other side of the oil filter 1. The length of the flow plate 5 is less than the width of the internal cavity of the oil filter 1. With this structure, when the oil-water mixture flows to the first few flow plates 5, the mixture is blocked, further reducing its flow velocity and allowing it to flow at a slower speed, effectively accelerating the stratification of the oil-water mixture. The multiple flow plates 5 are arranged in an alternating pattern, resulting in multiple flow ports 501. The inner wall of the oil filter 1 has a longer travel distance, and the alternating arrangement of the multiple flow plates 5 greatly increases the travel distance of the oil-water mixture from one end of the oil filter 1 to the other, increasing the flow time and travel distance, thus allowing sufficient oil and water stratification.

[0034] In a preferred embodiment, the oil return mechanism 7 includes a housing 701 with two mounting slots 702. A rotating oil suction roller 703 is mounted on each mounting slot 702. Multiple cylinders 708 are located at the bottom of the housing 701 and are mounted on the oil collection tank 6. A scraper 705 is located on one side of the oil suction roller 703. This structure drives the cylinders 708 to raise and lower the housing 701 relative to the oil collection tank 6.

[0035] In the preferred embodiment, the scraper 705 is mounted on the mounting groove 702, and the oil return mechanism 7 includes a first motor 704. A main bevel gear 706 is mounted on the output shaft of the first motor 704, and a meshing driven bevel gear 707 is mounted on the main bevel gear 706. A rotating shaft 7031 is mounted on the oil suction roller 703, and the driven bevel gear 707 is mounted on the rotating shaft 7031. A third pump body is mounted on the housing 701. With this structure, the first motor 704 is driven to rotate the main bevel gear 706, which in turn rotates the driven bevel gear 707, causing the two oil suction rollers 703 to roll and suck up oil. The scraper 705 hangs the oil sucked up by the oil suction rollers 703 into the housing 701, and the third pump body is driven to transport the sucked oil to the buffer zone 101 for a second oil-water separation.

That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
