Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a multi-stage filtration inclined plate oil separator. Background Technology

[0002] Oil separators utilize the difference in specific gravity between suspended solids and water in wastewater to achieve separation. In water treatment, oil separators are needed to separate oil from wastewater.

[0003] A search revealed that application number CN201510508065.1 discloses a multi-stage filtration and separation oil separator, comprising a slag basket, a first oil separator plate, a second oil separator plate, a third oil separator plate, a first oil scraper, a second oil scraper, an oil collecting plate, and a tank body with an internal cavity. Three slag discharge ports are located at the bottom of the tank body. The first and second oil separator plates are positioned in the middle of the internal cavity of the tank body. The oil collecting plate is placed at an angle on the left side of the internal cavity of the tank body, and an oil extraction port is located at the bottom left side of the oil collecting plate. The third oil separator plate is fixedly connected to the right edge of the oil collecting plate, and its height is lower than that of the second oil separator plate. The first oil scraper is located to the upper left of the second oil separator plate, and the second oil scraper is located to the upper left of the third oil separator plate. This invention incorporates multiple oil scraping devices, which can effectively reduce impurities in the scraped oil, easing the burden on subsequent impurity removal work.

[0004] When this technical solution is used, impurities floating on top of the solution are scraped off by the oil scraper and fall into the oil collection plate along with the oil. This requires workers to remove the oil and internal impurities, which is very inconvenient and affects the oil separation effect.

[0005] Therefore, we propose a multi-stage filtration inclined plate oil separator. Utility Model Content

The oil scraping blades are arranged in a circle and fixedly connected to the outer wall of the rotating shaft. The baffle is fixedly connected to the inner walls of both sides of the oil separator body and located at the top of the oil scraping blades. The baffle is arc-shaped and has a gap area larger than that between the two oil scraping blades. Multiple filter holes are arranged in a matrix on the baffle.

[0013] The scraper blade has multiple linearly arranged sliding holes at the end away from the rotating shaft. A drain rod is slidably connected to the inner wall of the sliding hole. The end of the drain rod away from the rotating shaft is a frustum-shaped block with arc-shaped cross-sections at both ends, while the end of the drain rod near the rotating shaft is cylindrical.

[0030] Example 1: A multi-stage filtration inclined plate oil separator, such as Figure 1 and Figure 2 As shown, including

[0031] The oil separator body 1 has an oil separator plate 3 in the middle for separation, a slag basket 2 for separating slag on the right side of the oil separator body 1, and an oil collection plate 4 for collecting oil on the right side of the oil separator body 1.

[0032] The discharge port 6 is located at both ends of the bottom of the oil separator body 1 and on one side of the oil collecting plate 4. Both ends of the bottom of the oil separator body 1 are inclined. The discharge port 6 is located at the bottom of both ends of the bottom of the oil separator body 1. The outer wall of the oil separator body 1 is provided with a fixing hole on one side of the oil collecting plate 4. The discharge port 6 is fixedly connected to the inner wall of the fixing hole.

[0033] The oil scraping assembly is located on the inner wall of the oil separator body 1 at the top of the oil collection plate 4. The oil scraping assembly includes a rotating shaft 9 for driving and an oil scraping plate 5 for scraping oil.

[0034] An isolation component is disposed on the inner wall of the oil separator body 1 and located on one side of the oil scraper 5. The isolation component includes a baffle 7.

[0035] like Figure 3 As shown, the rotating shaft 9 is connected to the inner walls of both sides of the oil separator body 1 via a motor. The oil scraper 5 is arranged in a circle and fixedly connected to the outer wall of the rotating shaft 9. The baffle 7 is fixedly connected to the inner walls of both sides of the oil separator body 1 and located at the top of the oil scraper 5. The baffle 7 is arc-shaped and has a gap area larger than that between the two oil scraper 5. The baffle 7 has multiple filter holes 8 arranged in a matrix.

[0036] When oil is scraped from the top, the motor drives the fixed shaft 10 to rotate, which in turn drives the scraper 5 to rotate synchronously, scraping the oil and impurities floating on the top into the gaps of the scraper 5. When the scraper 5 rotates to the top of the oil collecting plate 4, the impurities in the gaps of the scraper 5 can be blocked by the filter holes 8 on the baffle 7, and the oil can fall into the top of the oil collecting plate 4 through the filter holes 8. The oil is then discharged through the oil collecting plate 4 and the discharge port 6 on it. The impurities in the gaps of the scraper 5 can rotate with the scraper 5 to the bottom and fall down.

[0037] By using the isolation components, impurities floating on top can be isolated, preventing them from being discharged along with the oil, which would hinder the processing of impurities in the oil, causing inconvenience and affecting the oil separation effect.

[0038] like Figure 4 and Figure 5 As shown, the scraper blade 5 has multiple linearly arranged sliding holes at the end away from the rotating shaft 9. A drain rod 15 is slidably connected to the inner wall of the sliding holes. The end of the drain rod 15 away from the rotating shaft 9 is a frustum-shaped block with arc-shaped cross-sections at both ends, and the end of the drain rod 15 near the rotating shaft 9 is cylindrical.

[0039] A rotating seat 16 is rotatably connected to the sliding hole, and a dredging rod 15 is slidably connected to the inner wall of the rotating seat 16. A return spring 14 for providing elastic force is fixedly connected to the wall surface opposite to the dredging rod 15 and the rotating seat 16.

[0040] When the scraper blade 5 rotates, the unblocking rod 15 on the scraper blade 5 rotates to the axis of the filter hole 8. The unblocking rod 15 can then be driven into the filter hole 8 by the elastic force of the return spring 14 to unblock the filter hole 8. When the unblocking rod 15 rotates out of the axis of the filter hole 8, the unblocking rod 15 can be driven into the rotating seat 16 by the pressure of the inner wall of the filter hole 8 on the arc surface. Then the unblocking rod 15 can enter and exit the filter hole 8 in sequence to unblock the impurities in the filter hole 8 and prevent the filter hole 8 from becoming blocked.

[0041] By using the unblocking rod 15, which moves in and out of the filter hole 8 in sequence, the filter hole 8 can be unblocked, preventing impurities from clogging the filter hole 8 and affecting the efficiency of oil passage.

[0042] like Figure 6 As shown, the inner wall of the rotating seat 16 has multiple grooves 17 arranged in a circle, and the outer wall of the unblocking rod 15 near the rotating shaft 9 is fixedly connected to multiple guide rails 18 arranged in a circle. The guide rails 18 are slidably connected to the inner wall of the grooves 17.

[0043] like Figure 4 and Figure 5 As shown, a through rotating hole is provided in the oil scraper 5, which extends to the inner wall of the rotating shaft 9. A drive shaft 12 is rotatably connected to the inner wall of the rotating hole. One end of the drive shaft 12 is fixedly connected to the axial position of the rotating seat 16, and the other end of the drive shaft 12 is fixedly connected to the axial position of the second bevel gear 13.

[0044] Both ends of the rotating shaft 9 are provided with through holes, and a fixed shaft 10 is provided in the through holes. Both ends of the fixed shaft 10 are fixedly connected to the inner wall of the oil separator body 1. Multiple first bevel gears 11 arranged in a linear pattern are fixedly connected to the outer wall of the fixed shaft 10, and second bevel gears 13 mesh with the outer wall of the first bevel gears 11.

[0045] When the scraper blade 5 rotates, the drive shaft 12 inside it rotates synchronously. One end of the fixed shaft 10 is fixedly connected to the inner wall of the oil separator body 1, and there is a relative rotation between it and the drive shaft 12. Under the drive of the meshing first bevel gear 11 and the second bevel gear 13, the drive shaft 12 can be driven to rotate. The drive shaft 12 can drive the unblocking rod 15 to rotate through the rotating seat 16 and the sliding groove 17 on it. The unblocking rod 15 can improve the cleaning effect of the filter hole 8 by rotating itself as it enters and exits the filter hole 8.

[0046] With the fixed shaft 10 in place, the unblocking rod 15 can rotate when it enters and exits the filter hole 8, thereby improving the cleaning effect on the filter hole 8 and further preventing the filter hole 8 from becoming clogged and affecting the efficiency of oil passage.

[0047] The working principle of this utility model is as follows: When water treatment is required, the raw material is introduced into the oil separator body 1 through the slag basket 2. At this time, the larger impurities in the water can be separated by the slag basket 2, and the water and oil can fall to the other side through the oil separator plate 3. After the oil is scraped by the oil scraper plate 5, the oil is discharged through the oil collection plate 4 and the discharge port 6 on it. The remaining solution can be discharged through the discharge ports 6 at both ends of the bottom.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
