Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and in particular to a hydrocyclone oil separator. Background Technology

[0002] The coarsely separated oil phase discharged from the DGF tank drain still contains a large amount of water. If it directly enters the downstream treatment equipment, it will cause a surge in the subsequent system's processing capacity and increase energy consumption. Therefore, a hydrocyclone is needed to treat it. The hydrocyclone performs secondary oil-water separation on the oil-containing water discharged from the DGF, concentrating the oil phase and reducing the total oil phase discharge flow rate, thereby reducing the processing pressure on the downstream equipment from the source and improving the oil separation efficiency of the overall water treatment system. The number of hydrocyclones installed varies depending on the drainage volume. If the water flow rate increases or decreases and the number of hydrocyclones needs to be increased or decreased, the upstream DGF oil discharge pipe and the downstream return water pipe must be disassembled first, and then the oil separator assembly must be hoisted and removed as a whole before adding or removing the hydrocyclones. This results in excessive downtime, which can lead to interruption or significant reduction in the system's processing capacity. Furthermore, repeated disassembly and hoisting of pipes will significantly increase costs and waste resources. Summary of the Invention

[0003] In view of the problems existing in the above and / or existing hydrocyclone oil separators, the present invention is proposed.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0028] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a hydrocyclone oil separator. The hydrocyclone oil separator includes a main component 1, including a pipe 11. A support plate 12 is disposed inside the pipe 11. A cyclone tube 13 is inserted into the support plate 12. A pressure plate 14 is disposed at the top of the cyclone tube 13. Multiple slots are provided on both the pressure plate 14 and the support plate 12 for installing and fixing the cyclone tube 13. An appropriate number of cyclone tubes 13 are installed according to the drainage volume. The inlet of the cyclone tube 13 is made of holes evenly distributed around the circumference. The guide vanes inside the cyclone tube form a vortex. Oil and water are separated by the centrifugal force generated by the difference in oil and water density. It can remove oil droplets with a particle size of 20 micrometers or larger from the water. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0029] A water inlet pipe 18 is fixed on one side of the pipe 11. The water inlet pipe 18 is connected to the upstream drainage and is used to introduce water into the pipe 11. A water outlet pipe 15 is fixed at the bottom of the pipe 11. The water outlet pipe 15 is connected to the pipe 11 by flange bolts and is connected to the downstream drainage to discharge the separated water.

[0030] The pipe 11 is provided with a through groove 11-1. By setting the through groove 11-1, the pipe 11 can be disassembled and inserted into the pipe 11 to complete the addition or removal of the cyclone tube 13. This greatly shortens the construction efficiency when installing the cyclone tube 13, avoids long-term downtime from affecting the processing efficiency of the oil separator, and significantly reduces costs and resource waste.

[0031] A baffle 16 is hinged to one side of the pipe 11. The baffle 16 is used to block the through groove 11-1. When the baffle 16 is closed, it can prevent the water inside the pipe 11 from flowing out through the through groove 11-1. The baffle 16 and the through groove 11-1 are sealed to prevent water leakage.

[0032] Auxiliary component 2, which is set on pipe 11, includes a fastener 21. The fastener 21 includes a positioning ring 211 fixed to the inner wall of pipe 11. The positioning ring 211 has a notch near the through groove 11-1. A movable ring 212 is engaged on the outside of the positioning ring 211. The positioning ring 211 is used to support and position the movable ring 212.

[0033] A positioning block 213 is fixed inside the movable ring 212. A threaded column 214 is rotatably connected to the positioning block 213 through a bearing. There are multiple positioning blocks 213 and threaded columns 214, which are evenly distributed in a ring inside the movable ring 212. A threaded hole 14-1 is opened on the pressure plate 14, and the threaded column 214 is internally threaded to the threaded hole 14-1.

[0034] A fixed ring 215 is rotatably connected to the inner wall of the pipe 11. The fixed ring 215 is rotatably connected to the inner wall of the pipe 11 through an annular block and an annular groove. An annular groove 12-1 is opened on the support plate 12. The fixed ring 215 is movably connected to the annular groove 12-1. A sealing gasket is provided between the fixed ring 215 and the annular groove 12-1. A pressure ring 216 is fixed inside the outlet pipe 15. The pressure ring 216 contacts the support plate 12. After the pressure ring 216 presses the support plate 12 tightly, the support plate 12 can rotate without affecting the sealing performance.

[0035] When installing the vortex tube 13, attach the support plate 12 to the fixing ring 215, and then fix the outlet pipe 15 to the pipe 11. At this time, the pressure ring 216 will press and fix the support plate 12. Then, insert the vortex tube 13 into the slots on the support plate 12 in sequence. Then, align the threaded hole 14-1 on the pressure plate 14 with the threaded post 214, and rotate the threaded post 214 to move the pressure plate 14 so that the slot on the pressure plate 14 fits the top of the vortex tube 13. After the pressure plate 14 and the movable ring 212 are tightly fitted, the installation of the vortex tube 13 can be completed. Finally, connect the pipe 11 to the upstream drain pipe.

[0036] When it is necessary to add or remove the cyclone tube 13, simply open the baffle 16, then rotate the threaded column 214 to separate the pressure plate 14 from the top of the cyclone tube 13. This will make room for the installation or removal of the cyclone tube 13, and then the cyclone tube 13 can be removed through the through groove 11-1. Example

[0037] Reference Figures 2-6This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the auxiliary component 2 also includes a rotating component 22, which includes a gear 221 fixed to the outside of the threaded post 214. The number of gears 221 corresponds to the number of threaded posts 214. A gear ring 222 is provided on one side of the movable ring 212. The gear ring 222 meshes with the gear 221. By rotating the gear ring 222, the gear 221 is driven to rotate, and the threaded post 214 is driven to rotate through the gear 221. Thus, multiple threaded posts 214 can be rotated simultaneously while rotating a single gear ring 222, which facilitates the adjustment of the position of the pressure plate 14.

[0039] The gear ring 222 has multiple insertion holes 222-2 on its outer side, which are evenly distributed in a ring on the outer side of the gear ring 222. When rotating the gear ring 222, if it is difficult to continue rotating the gear ring 222 manually, an additional extension rod can be used to insert into the insertion hole 222-2 through the through slot 11-1. The gear ring 222 can be rotated with the assistance of the extension rod. Since there are multiple insertion holes 222-2, the extension rod can be inserted into the insertion hole 222-2 at any angle when the gear ring 222 is rotated.

[0040] A pin is fixed on the baffle 16. When the baffle 16 is closed, the pin will be inserted into the socket 222-2. At this time, the two can be used to limit the toothed ring 222 and prevent the toothed ring 222 from rotating due to the impact of water flow.

[0041] Specifically, a locking block 223 is fixed on one side of the movable ring 212. The locking block 223 is T-shaped, and a slot 222-1 is provided on the toothed ring 222. The locking block 223 is movably connected to the slot 222-1. The two cooperate to connect the toothed ring 222 and the movable ring 212, so that the toothed ring 222 can rotate on one side of the movable ring 212 without separating from the movable ring 212.

[0042] Specifically, the auxiliary component 2 also includes locking components 23. There are three sets of locking components 23, which are evenly distributed in a straight line on one side of the pipe 11. Each locking component 23 includes a support block 231 fixed to one side of the pipe 11. The support block 231 is internally threaded with a threaded rod 232. The end of the threaded rod 232 is rotatably connected to a pressing block 233. After the baffle 16 is closed, rotating the threaded rod 232 drives the pressing block 233 to move, so that the pressing block 233 contacts the baffle 16 and presses the baffle 16, thereby fixing the baffle 16 and preventing the baffle 16 from opening due to water pressure. Example

[0043] Reference Figure 7 and Figure 8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0044] Specifically, a positioning post 234 is fixed on one side of the extrusion block 233. One end of the positioning post 234 passes through the support block 231 and is movably connected to the support block 231. The positioning post 234 is used to guide and position the extrusion block 233 to prevent the extrusion block 233 from shifting when it moves.

[0045] Specifically, the auxiliary component 2 also includes a limiting member 24, which includes a fixing block 241 fixed to one side of the positioning ring 211. A limiting post 242 is inserted into the fixing block 241. A limiting hole 212-1 is opened on the movable ring 212. The limiting post 242 engages with the limiting hole 212-1. The two cooperate to limit the movable ring 212, so as to prevent the movable ring 212 from rotating synchronously when the gear ring 222 is rotated, which would result in the inability to lock the pressure plate 14.

[0046] Specifically, a connecting rod 243 is fixed to one end of the limiting post 242. The connecting rod 243 is arc-shaped and is used to connect and fix the two limiting posts 242. The two limiting posts 242 can be removed at the same time through the connecting rod 243.

[0047] Specifically, both the pressure plate 14 and the support plate 12 are fitted with plugs 17. The plugs 17 are cylindrical T-shaped and fit tightly into the slots on the pressure plate 14 and the support plate 12 to seal the empty slots and prevent water from flowing out through the empty slots.

[0048] Specifically, a handle 16-1 is fixed to one side of the baffle 16, which allows the user to open or close the baffle 16.

[0049] In use, when it is necessary to add or remove the cyclone tube 13, rotate the threaded rod 232 to move the extrusion block 233, causing the extrusion block 233 to separate from the baffle 16. At this time, the restriction on the baffle 16 is released. Then, the baffle 16 is opened, and the gear ring 222 is rotated to drive the gear 221 to rotate. The gear 221 then drives the threaded column 214 to rotate, causing the pressure plate 14 to move away from the cyclone tube 13 and separate it from the cyclone tube 13. At this time, the fixation on the cyclone tube 13 is released. Then, pull the connection. Rod 243 drives the limiting post 242 to move, causing the limiting post 242 to separate from the limiting hole 212-1 and releasing the restriction on the movable ring 212. At this time, the pressure plate 14 and the support plate 12 can be rotated, and the cyclone tube 13 can be installed or removed along their circumference without having to disassemble the entire pipe 11. This improves construction efficiency, avoids long-term downtime affecting the oil separator's processing efficiency, and significantly reduces costs and resource waste. After the addition or removal is completed, it can be fixed.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
