Description

Technical Field

[0001] This utility model relates to the field of centrifugal oil filtration technology, and in particular to a centrifugal oil separation filter that is easy to clean. Background Technology

[0002] Centrifugal oil separators are core equipment in food processing and small-scale industrial oil treatment. Their working principle is to generate centrifugal force through the high-speed rotation of the drum, which throws the oil residue in the oil onto the inner wall of the drum, thereby achieving the separation and purification of oil and oil residue. The outer cylinder serves as the receiving cavity, and together with the end cover, it houses the drum. The end cover and the outer cylinder are generally fixed with a multi-bolt connection structure. Since a large amount of oil residue will adhere to the inner wall of the drum after centrifugation, it is necessary to periodically insert a shovel to clean the inner wall of the drum. However, due to the complexity of disassembling the bolt connection, operators usually choose not to disassemble the end cover and directly insert the shovel into the inner cylinder through the feed port on the end cover to clean it. The feed port was originally designed to meet the needs of introducing the oil to be filtered. Its limited size restricts the movement of the shovel after it is inserted, making it impossible to fully cover all areas of the inner wall of the drum, which is not convenient for cleaning the oil residue.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an 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 excludes other embodiments.

[0029] Example 1 Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a centrifugal oil separator that is easy to clean. The centrifugal oil separator that is easy to clean includes a main component 1, including an outer cylinder 11. An end cover 12 is provided on the outer cylinder 11. A rotating drum 13 is provided inside the outer cylinder 11. An inlet 12-1 is provided on the end cover 12. The rotating drum 13 can rotate in the space formed by the outer cylinder 11 and the end cover 12. Untreated oil enters the rotating drum 13 and is separated by the rotation of the rotating drum 13. After long-term use, oil residue will be attached to the inner wall of the rotating drum 13. Therefore, it is necessary to clean it regularly. This is the prior art. This solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0030] Mounting component 2, located inside the outer cylinder 11, includes mounting component 21. The mounting component 21 allows the outer cylinder 11 and end cap 12 to be quickly installed, so that they can be quickly separated when cleaning is required, and the upper space of the outer cylinder 11 can be fully opened, expanding the range of operation of the cleaning tool and facilitating cleaning. The part of the outer cylinder 11 that contacts the end cap 12 has a thicker wall to accommodate the mounting component 21.

[0031] The bottom of the end cap 12 is fixed with a locking block 211, and the outer cylinder 11 is provided with a locking groove 11-1. The bottom of the end cap 12 is fixed with a sealing ring 212. The locking block 211 is rectangular, and the locking groove 11-1 is in a corresponding shape. The sealing ring 212 is used for sealing and is made of rubber. When the locking block 211 and the locking groove 11-1 are locked together and prevent them from separating, the relative position of the end cap 12 and the outer cylinder 11 will be locked, and the two can be connected.

[0032] The mounting assembly 2 also includes a locking member 22 located inside the outer cylinder 11. The locking member 22 locks the engagement state of the locking block 211 and the slot 11-1, ensuring the stability of the connection between the end cap 12 and the outer cylinder 11. The locking member 22 includes a locking block 221 that slides inside the outer cylinder 11. A first spring 222 is fixed on one side of the locking block 221, and the other end of the first spring 222 is fixed on the outer cylinder 11. A locking slot 211-1 is provided on the locking block 211. The first spring 222 applies a continuous pushing force to the locking block 221, ensuring that the locking block 221 can engage with the locking slot 211-1. When the two are engaged, the locking block 211 will not be able to separate from the slot 11-1.

[0033] One end of the locking block 221 is inclined. By setting it at an inclination, when the end cap 12 is installed on the outer cylinder 11, the locking block 211 is aligned with the locking groove 11-1. Then, the end cap 12 is slowly placed downward on the outer cylinder 11. At this time, the locking block 211 will first contact the inclined surface of the locking block 221. The first spring 222 is compressed and will not hinder the locking block 211 from engaging with the locking groove 11-1. When the locking block 221 and the locking groove 211-1 are coaxial, the first spring 222 makes the two engage, thereby preventing the locking block 211 from separating from the locking groove 11-1.

[0034] Example 2 Reference Figures 3-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, there are four card blocks 211 and four locking pieces 22, which correspond one-to-one with card blocks 211.

[0036] Specifically, an inclined block 223 is slidably disposed inside the outer cylinder 11. An extension block 224 is fixed to the bottom of the inclined block 223. There are four inclined blocks 223 and four extension blocks 224, each corresponding to a locking block 221. One end of the extension block 224 extends to the outside of the outer cylinder 11, and an annular ring 225 is fixed to the bottom of the extension block 224. The annular ring 225 connects the four extension blocks 224 together, and all the extension blocks 224 and the inclined block 223 can move up and down synchronously. Multiple pressure plates 226 are fixed on the annular ring 225. The pressure plates 226 are L-shaped, which facilitates pressing the annular ring 225, thereby driving the extension blocks 224 and the inclined block 223 to move downward synchronously.

[0037] Specifically, the locking block 221 has an inclined groove 221-1 and a sliding groove 221-2, which are connected to each other. The inclined block 223 can contact the inclined groove 221-1, and the extension block 224 can slide in the sliding groove 221-2. The width of the sliding groove 221-2 is narrower than that of the inclined groove 221-1. When the extension block 224 moves downward, the inclined block 223 moves downward simultaneously and contacts the inclined groove 221-1, and squeezes the inclined groove 221-1, thereby compressing the first spring 222. The locking block 221 separates from the locking groove 211-1. At this time, the extension block 224 will slide in the sliding groove 221-2, thereby releasing the limit of the locking block 211 and the locking groove 11-1. At this time, lifting the end cover 12 upward can separate it from the outer cylinder 11.

[0038] Specifically, a second spring 227 is fixed on the annular ring 225, and the other end of the second spring 227 is fixed on the outer cylinder 11. The second spring 227 applies a continuous pushing force to the annular ring 225, so that the inclined block 223 does not contact the inclined groove 221-1 when there is no other external force, thus avoiding affecting the engagement of the locking block 211 and the locking groove 11-1. The second spring 227 is also used for the reset of the annular ring 225, the extension block 224 and the inclined block 223.

[0039] Example 3 Reference Figures 5-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] Specifically, the installation component 2 also includes an auxiliary component 23 located on one side of the drum 13. By setting the auxiliary component 23, when the centrifuge is in operation, the drum 13 rotates and uses centrifugal force to lock the position of the locking block 221, ensuring that the locking block 211 will not separate from the slot 11-1.

[0041] The auxiliary component 23 includes a fixing ring 231 fixed to the outside of the drum 13. The fixing ring 231 has a first through groove 231-1. A small arc plate 232 is slidably disposed in the first through groove 231-1. A pressing block 233 is fixed to one side of the small arc plate 232. The pressing block 233 can slide inside the outer cylinder 11. One end of the pressing block 233 is coaxial with the locking block 221. The pressing block 233 moves toward the locking block 221 and can apply a pushing force to the locking block 221 to move toward the locking groove 211-1. The first through groove 231-1 is provided so that when the drum 13 drives the fixing ring 231 to rotate, the small arc plate 232 will not obstruct the rotation of the fixing ring 231.

[0042] Specifically, a second through groove 231-2 is provided on the fixing ring 231. The first through groove 231-1 and the second through groove 231-2 are connected. A large arc plate 234 is slidably arranged in the second through groove 231-2. The large arc plate 234 can contact the small arc plate 232. When the large arc plate 234 moves towards the edge of the fixing ring 231, it will squeeze the small arc plate 232, causing the small arc plate 232 to move towards the edge of the fixing ring 231 simultaneously, thereby driving the squeezing block 233 to move towards the locking block 221.

[0043] Specifically, a movable groove 231-3 is provided on the fixed ring 231. A counterweight 235 and a movable block 236 are slidably arranged in the movable groove 231-3. The movable groove 231-3 and the movable block 236 are both T-shaped. The T-shape allows the movable block 236 to slide smoothly in the movable groove 231-3 without separating from it. One end of the movable block 236 is fixed to the large arc plate 234.

[0044] When the drum 13 rotates, under the action of centrifugal force, the counterweight 235 will move towards the edge of the fixed ring 231 within the moving groove 231-3, thereby pushing the moving block 236 to move. This causes the large arc plate 234 to move towards the edge of the fixed ring 231, which will squeeze the small arc plate 232. This causes the small arc plate 232 to move towards the edge of the fixed ring 231 simultaneously, thereby driving the squeezing block 233 to move towards the locking block 221. This makes the locking block 221 more tightly engaged with the locking groove 211-1, preventing the end cap 12 from separating from the outer cylinder 11 during centrifugation.

[0045] The state shown in the figure is that after the drum 13 rotates, the counterweight 235 has pushed the squeezing block 233 close to the locking block 221 under the action of centrifugal force.

[0046] Specifically, there are four large arc plates 234 and four small arc plates 232. When the large arc plate 234 is located closest to the edge of the fixing ring 231, the distance between two adjacent large arc plates 234 is the largest. This distance is smaller than the length of the small arc plate 232, thus ensuring that no matter what angle the rotating drum 13 drives the fixing ring 231 to rotate, the small arc plate 232 can be pushed by at least one large arc plate 234 and move towards the locking block 221, thereby ensuring the limiting effect on the locking block 221.

[0047] There are four counterweights 235 and four moving blocks 236. The cooperation between the moving slots 231-3 and the moving blocks 236 can restrict the large arc plate 234 to move linearly only within the second through slot 231-2.

[0048] Specifically, a support buffer 14 is provided on the outer side of the outer cylinder 11 to support the entire centrifuge device and reduce shock. A positioning groove 121 is fixed on the end cover 12, and a positioning ring 131 is fixed on the drum 13. The size of the positioning groove 121 is slightly larger than that of the positioning ring 131. The positioning ring 131 can slide in the positioning groove 121 to ensure that the center of the drum 13 and the end cover 12 are aligned.

[0049] When cleaning is required after prolonged use, press the pressure plate 226 to drive the annular ring 225 and the four sets of extension blocks 224 and the inclined block 223 to move downwards synchronously. The inclined block 223 moves downwards and contacts the inclined groove 221-1, squeezing the inclined groove 221-1, thereby compressing the first spring 222. The four locking blocks 221 are simultaneously separated from the corresponding locking grooves 211-1, thereby releasing the limiting position of the locking block 211. At this time, lifting the end cover 12 upwards can separate it from the outer cylinder 11, so that the upper space of the outer cylinder 11 is fully opened, expanding the range of operation of cleaning tools. Operators can directly insert tools such as shovels and high-pressure cleaning guns into the inside of the drum 13 without being limited by the size constraints of the original feed port 12-1. The tool angle can be adjusted to facilitate the cleaning of oil residue.

[0050] After cleaning, move the end cap 12 above the outer cylinder 11, align the locking block 211 with the locking groove 11-1, and then slowly place the end cap 12 downwards onto the outer cylinder 11. At this time, the locking block 211 will first contact the inclined surface of the locking block 221, and the first spring 222 will be compressed, which will not hinder the engagement of the locking block 211 with the locking groove 11-1. When the locking block 221 and the locking groove 211-1 are coaxial, the first spring 222 will engage the two, thereby preventing the locking block 211 from separating from the locking groove 11-1.

[0051] In operation, the rotating drum 13, under the action of centrifugal force, causes the counterweight 235 to move towards the edge of the fixed ring 231 within the moving groove 231-3, thereby pushing the moving block 236 to move. This causes the large arc plate 234 to move towards the edge of the fixed ring 231, which in turn squeezes the small arc plate 232, causing the small arc plate 232 to move synchronously towards the edge of the fixed ring 231. This, in turn, drives the squeezing block 233 to move towards the locking block 221, causing the locking block 221 to engage with the locking groove. 211-1 engages more tightly, preventing the end cap 12 from separating from the outer cylinder 11 during centrifugation. When the drum 13 stops rotating, pressing the pressure plate 226 separates the locking block 221 from the locking groove 211-1. The locking block 221 applies a pushing force to the squeezing block 233, thereby causing the small arc plate 232, the large arc plate 234, the counterweight block 235, and the moving block 236 to move towards the center of the fixed ring 231 and reset, without hindering the separation of the locking block 221 from the locking groove 211-1.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
