Description

Technical Field

[0001] The present invention relates to the technical field of separators, and specifically to an oil fine separator. Background Art

[0002] The oil fine separator is mainly used to separate lubricating oil and compressed gas. It is a vulnerable part that often needs to be replaced and is relatively expensive. It is actually a porous filtering material. Before the oil-gas mixture enters the filtering element, oil droplets with a diameter larger than the pore diameter of the element material will be filtered out on the surface of the element. Then, by changing the shape and size of the internal flow channels of the filtering material, small-diameter oil droplets entering its interior can coalesce into large-diameter oil droplets on the fibers of the material under the action of inertial force and the like, and be filtered out. The oil fine separator core generally uses materials such as ultra-fine glass fiber developed specifically for this purpose, achieving good oil removal effect, long life, and small pressure drop. The oil fine separator core produced by professional manufacturers can already reduce the oil content in the gas to 1-2 ppm.

[0003] However, the current oil fine separator needs to be disassembled and cleaned multiple times after use, and the lubricating oil will contain some impurities during long-term use. After the impurities block the filtering material, the filtering effect will be further reduced. Therefore, there is an urgent need for an oil fine separator to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an oil fine separator to solve the problems raised in the above background art.

[0005] The technical solution of the present invention is: an oil fine separator, including a housing, and further including:

[0006] A core body, which is used for filtering the mixture and is located inside the housing. A partition is installed on the inner wall of the circumferential surface of the housing, and an annular groove is provided on the outer wall of the top of the partition. A connecting ring is fixedly connected to the inner wall of the annular groove. A connecting groove is provided on the outer wall of the top of the connecting ring, and a piston ring is installed on the inner wall of the connecting groove. Equally spaced buffer springs are installed on the outer wall of the bottom of the piston ring, and the bottom outer wall of the buffer spring is fixedly connected to the bottom inner wall of the connecting groove;

[0007] A support ring, which is fixed on the outer wall of the circumference of the core body. The core body is matched with the inner wall of the connecting groove. The core body includes an oil collecting layer, a coarse filtration layer, and a fine filtration layer. A fixing groove is provided on the outer wall of the bottom of the support ring, and a fixing ring matched with the fixing groove is installed on the outer wall of the top of the partition;

[0008] A cleaning mechanism, which is used for scraping and cleaning the inner wall of the core body and is located inside the housing. A liquid inlet pipe is inserted into the outer wall of the bottom of the housing. The cleaning mechanism includes a liquid spraying pipe that rotates on the top of the circumferential outer wall of the liquid inlet pipe. The circumferential outer wall of the liquid spraying pipe is inserted with arc-shaped housings distributed at equal intervals. One end of the outer wall of the arc-shaped housing is inserted with liquid outlet nozzles distributed at equal intervals. One side of the outer wall of the arc-shaped housing is provided with second brush hairs distributed at equal intervals. The circumferential outer wall of the liquid spraying pipe is provided with first brush hairs distributed at equal intervals. The outer walls of the first brush hairs and the second brush hairs are slidably connected to the inner wall of the core body.

[0009] Preferably, the top outer wall of the partition plate is provided with tapered holes distributed at equal intervals. A protective housing is installed at the bottom of the circumferential outer wall of the liquid spraying pipe. The separated impurities flow down through the tapered holes on the partition plate to the bottom of the housing. The diameter of the top of the tapered hole is larger than that of the bottom, which can make it difficult for the filtered impurities to rise after falling below the housing.

[0010] Preferably, a fixed screw block is installed on the top outer wall of the housing. The top of the circumferential outer wall of the fixed screw block is rotationally connected with a rear cover through a thread. The top outer wall of the rear cover is rotationally connected with a screw rod through a thread.

[0011] Preferably, the bottom outer wall of the screw rod is rotationally connected with a circular block through a bearing. A circular groove is opened on the bottom outer wall of the circular block. The inner wall of the circular groove is rotationally connected with a sealing block through a bearing. A fixing groove matching the core body is opened on the bottom outer wall of the sealing block. Rotating the screw rod drives the sealing block on the circular block to descend, so that the fixing groove on the sealing block limits and fixes the core body, thereby enabling quick extrusion sealing of the core body.

[0012] Preferably, an air outlet pipe is inserted into one side outer wall of the housing, and a controller is installed on one end outer wall of the housing.

[0013] Preferably, an opening is opened on one end outer wall of the housing, and a sealing door panel is joined to the inner wall of one side of the opening. After the work is completed, the collected impurities in the housing are cleaned by opening the sealing door panel, which facilitates the subsequent separation work.

[0014] Preferably, support frames are installed on both sides of the bottom outer wall of the housing, and a reinforcing plate is installed on the top outer wall of the support frames. The separator can be fixed at the working location through the reinforcing plate and the support frames to ensure the stability of the separator during work.

[0015] Preferably, support shells are inserted into the top outer wall of the protective housing at equal intervals, and one-way valves are inserted into the top outer wall of the support shells.

[0016] Preferably, a support groove is opened on the bottom outer wall of the support shell, and a filter screen plate is installed on the inner wall of the support groove. The flow direction of the one-way valve is from the inside of the protective housing to the outside.

[0017] The present invention provides an oil fine separator by means of improvement. Compared with the prior art, the following improvements and advantages are achieved:

[0018] First: By providing a connecting ring and a piston ring on the partition plate, the core is inserted into the interior of the housing, such that the core enters the piston ring on the connecting ring. Then, the fixing ring on the partition plate enters the support ring on the core. The rear cover is rotated by a thread on the fixing block, and the rotating screw rod drives the sealing block on the circular block to descend, such that the fixing groove on the sealing block limits and fixes the core. Thereby, the core can be quickly squeezed and sealed, improving the efficiency of disassembly and installation and ensuring the separation effect of lubricating oil and compressed gas;

[0019] Second: By providing a cleaning mechanism, the mixture is added to the housing through the liquid inlet pipe. The mixture is ejected through the arc-shaped housing and the liquid outlet nozzle on the liquid spraying pipe. The impact force of the ejected mixture drives the liquid spraying pipe to rotate. The rotation of the liquid spraying pipe can drive the first brush bristles and the arc-shaped housing and the second brush bristles to rotate. The first brush bristles and the second brush bristles can scrape and clean the inner wall of the core, preventing impurities in the mixture from clogging the core and improving the filtering efficiency of the compressed gas;

[0020] Third: By providing a tapered hole on the partition plate, the separated impurities flow down through the tapered hole on the partition plate to the bottom of the housing. Cooperating with the protective housing on the outer wall of the liquid spraying pipe, it can protect the falling impurities and prevent them from returning to the upper part of the housing again, improving the storage effect. The filtered mixture mixed with impurities moves to the lower part of the housing. The support housing, one-way valve, and filter mesh plate provided on the protective housing can make the mixture flow into the protective housing, further improving the impurity storage effect and making the device more perfect and reasonable.

[0032] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0033] The present invention provides an oil fine separator by improvement. The technical solution of the present invention is as follows:

[0034] Embodiment 1

[0035] As Figures 1 - 7 shown, an oil fine separator includes a housing 5 and further includes:

[0036] A core body 15 for filtering the mixture, located inside the housing 5. A partition board 14 is installed on the circumferential inner wall of the housing 5, and an annular groove is opened on the outer wall of the top of the partition board 14. A connection ring 24 is fixedly connected to the inner wall of the annular groove. A connection groove 21 is opened on the outer wall of the top of the connection ring 24, and a piston ring 25 is installed on the inner wall of the connection groove 21. A plurality of buffer springs 26 are installed on the outer wall of the bottom of the piston ring 25, and the bottom outer wall of the buffer springs 26 is fixedly connected to the bottom inner wall of the connection groove 21;

[0037] The support ring 17 is fixed to the outer circumferential wall of the core body 15. The core body 15 matches the inner wall of the connecting groove 21. The core body 15 includes an oil collecting layer 153, a coarse filter layer 152 and a fine filter layer 151. And a fixing groove 18 is provided on the outer wall of the bottom of the support ring 17. And a fixing ring 19 matching the fixing groove 18 is installed on the outer wall of the top of the partition plate 14. The core body 15 includes an oil collecting layer 153, a coarse filter layer 152 and a fine filter layer 151, which can perform multi-stage filtration on the mixture;

[0038] The cleaning mechanism is used for scraping and cleaning the inner wall of the core body 15 and is located inside the housing 5. A liquid inlet pipe 7 is inserted into the outer wall of the bottom of the housing 5. The cleaning mechanism includes a liquid spraying pipe 12 rotating on the top of the outer circumferential wall of the liquid inlet pipe 7. And arc-shaped shells 22 are inserted into the outer circumferential wall of the liquid spraying pipe 12 at equidistant intervals. A liquid outlet nozzle 28 is inserted into one end outer wall of the arc-shaped shell 22 at equidistant intervals. And second brush hairs 29 are installed on one side outer wall of the arc-shaped shell 22 at equidistant intervals. First brush hairs 23 are installed on the outer circumferential wall of the liquid spraying pipe 12 at equidistant intervals. The outer walls of the first brush hairs 23 and the second brush hairs 29 are slidably connected to the inner wall of the core body 15. The mixture is added into the housing 5 through the liquid inlet pipe 7. The mixture is sprayed out through the arc-shaped shells 22 and the liquid outlet nozzles 28 on the liquid spraying pipe 12. The impact force of the sprayed mixture will drive the liquid spraying pipe 12 to rotate. The rotation of the liquid spraying pipe 12 can drive the first brush hairs 23 and the arc-shaped shells 22 and the second brush hairs 29 to rotate. The first brush hairs 23 and the second brush hairs 29 can scrape and clean the inner wall of the core body 15, preventing impurities in the mixture from blocking the core body 15 and ensuring the filtering effect.

[0039] Further, tapered holes 20 are provided on the outer wall of the top of the partition plate 14 at equidistant intervals. And a protective housing 13 is installed on the bottom of the outer circumferential wall of the liquid spraying pipe 12. The separated impurities flow down through the tapered holes 20 on the partition plate 14 to the bottom of the housing 5. The diameter of the top of the tapered hole 20 is larger than that of the bottom, which can make the filtered impurities difficult to rise after falling below the housing 5. A sewage discharge pipe is inserted into the outer wall of the bottom of the housing 5, and an activated carbon mesh plate is installed on the inner wall of the sewage discharge pipe.

[0040] Further, a fixing screw block 2 is installed on the outer wall of the top of the housing 5. And a rear cover 1 is rotationally connected to the top of the outer circumferential wall of the fixing screw block 2 through a thread. And a screw rod 11 is rotationally connected to the top of the outer wall of the rear cover 1 through a thread, which is convenient for sealing the housing 5.

[0041] Further, the bottom outer wall of the screw rod 11 is rotationally connected to a circular block 27 through a bearing. And a circular groove is provided on the bottom outer wall of the circular block 27. A sealing block 10 is rotationally connected to the inner wall of the circular groove through a bearing. A fixing groove matching the core body 15 is provided on the bottom outer wall of the sealing block 10. Rotating the screw rod 11 drives the sealing block 10 on the circular block 27 to descend, so that the fixing groove on the sealing block 10 limits and fixes the core body 15, thereby enabling quick extrusion sealing of the core body 15.

[0042] Furthermore, an air outlet pipe 3 is inserted into the outer wall of one side of the housing 5, and a controller 4 is installed on the outer wall of one end of the housing 5.

[0043] Furthermore, an opening is provided on the outer wall of one end of the housing 5, and a sealing door panel 6 is joined to the inner wall of one side of the opening. After the work is completed, the sealing door panel 6 is opened to clean the impurities collected in the housing 5, facilitating the subsequent separation work.

[0044] Furthermore, support frames 9 are installed on both sides of the outer wall of the bottom of the housing 5. Threaded holes are provided on the outer wall of the top of the support frames 9, and a reinforcing plate 8 is installed on the outer wall of the top of the support frames 9. The separator can be fixed to the working location through the reinforcing plate 8 and the support frames 9 to ensure the stability of the separator during operation.

[0045] Working principle: First, the core body 15 is inserted into the interior of the housing 5, such that the core body 15 enters the piston ring 25 on the connecting ring 24. Then, the fixing ring 19 on the partition plate 14 enters the support ring 17 on the core body 15. The rear cover 1 is rotated by threading onto the fixing block 2. The screw rod 11 is rotated to drive the sealing block 10 on the circular block 27 to descend, such that the fixing groove on the sealing block 10 limits and fixes the core body 15, thereby enabling rapid extrusion and sealing of the core body 15. The mixture is added to the housing 5 through the liquid inlet pipe 7, and the mixture is ejected through the arc-shaped housing 22 and the liquid outlet nozzle 28 on the liquid spraying pipe 12. The impact force of the ejected mixture drives the rotation of the liquid spraying pipe 12. The rotation of the liquid spraying pipe 12 drives the rotation of the first brush bristles 23 and the arc-shaped housing 22 and the second brush bristles 29. The first brush bristles 23 and the second brush bristles 29 can scrape and clean the inner wall of the core body 15, preventing impurities in the mixture from clogging the core body 15 and ensuring the filtering effect. The core body 15 includes an oil collecting layer 153, a coarse filtering layer 152, and a fine filtering layer 151, and can perform multi-stage filtering on the mixture. The separated compressed gas is discharged through the air outlet pipe 3. The separated impurities and oil droplets flow down through the conical holes 20 on the partition plate 14 to the bottom of the housing 5. Cooperating with the protective housing 13 on the outer wall of the liquid spraying pipe 12, it can protect the falling impurities and prevent them from returning above the housing 5 again, improving the storage effect. After the work is completed, the electric valve on the inner wall of the sewage discharge pipe is opened to discharge the oil droplets filtered by the activated carbon filter mesh plate to the outside. Then, the sealing door panel 6 is opened to clean the impurities collected in the housing 5, facilitating the subsequent separation work. The separator can be fixed to the working location through the reinforcing plate 8 and the support frames 9 to ensure the stability of the separator during operation.
