[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 3 , a refined oil detection device, including an upper housing 1 and a lower housing 2. The bottom end of the upper housing 1 is fixedly connected to the top end of the lower housing 2, and a separation and detection mechanism. The separation and detection mechanism is arranged inside the upper housing 1 and the lower housing 2. The separation and detection mechanism includes a first bracket 302 fixedly connected to the top end of the upper housing 1. A motor 301 is fixedly connected to the middle of the first bracket 302. The centrifugal bucket 304 can be driven to rotate by the motor 301. The output shaft of the motor 301 is fixedly connected to a second bracket 303. The surface of the second bracket 303 is fixedly connected to the centrifugal bucket 304. The solid substances in the edible oil can be made to move away from the center of the centrifugal bucket 304 by the rotating centrifugal bucket 304, reducing the influence of the solid substances on the detection data of trans fatty acids in the edible oil during the subsequent detection process.

[0024] Among them, two support rods 307 are fixedly connected inside the lower housing 2. An oil receiving hopper 305 is fixedly connected between the two support rods 307. A pipeline 306 is communicated with the bottom of the oil receiving hopper 305. A detection chamber 308 is sleeved at the outlet end of the pipeline 306. An installation hanger 312 is fixedly connected to the outer arc surface of the oil receiving hopper 305. An infrared light source 311 is installed at the lower end of the installation hanger 312. The infrared light source 311 can emit infrared light. An infrared detector 309 is fixedly connected to the bottom end inside the lower housing 2. The infrared detector 309 can receive the infrared light emitted by the infrared light source 311 and further analyze the output signal of the infrared detector 309.

[0025] Among them, an infrared filter 310 is fixedly connected to the bottom end of the detection chamber 308. The infrared filter 310 can filter the incoming infrared light and filter out infrared light of other frequencies, thereby further improving the accuracy of the detection data of trans fatty acids in edible oil. A light-shielding cover 315 is fixedly connected to the lower end of the installation hanger 312 and the surface of the infrared detector 309. The light-shielding cover 315 can separate the external light source and reduce the interference of the external light source on the detection process, thereby further improving the accuracy of the detection data of trans fatty acids in edible oil. A rubber retaining ring 313 is fixedly sleeved on the outlet end of the oil delivery pipe 306. A housing door 314 is rotatably connected to the surface of the lower housing 2. When removing the detection chamber 308 for cleaning, the housing door 314 can be opened to remove the detection chamber 308 from the oil delivery pipe 306. When installing the detection chamber 308, the detection chamber 308 is fixed by the extrusion force and friction force between the rubber retaining ring 313 and the detection chamber 308.

[0026] By adopting the above technical solution, when detecting edible oil, the edible oil is injected into the centrifuge barrel 304, and then the centrifuge barrel 304 is driven to rotate by the motor 301. The solid substances in the edible oil can be separated from the center of the centrifuge barrel 304 by the action of centrifugal force. Then, the edible oil after centrifuging the solid substances flows into the oil receiving hopper 305 and flows into the detection chamber 308 through the oil delivery pipe 306. At this time, the edible oil is located on the infrared filter 310. When the infrared light source 311 emits infrared light to the infrared filter 310, the infrared detector 309 can receive the infrared light emitted by the infrared light source 311, detect the infrared light of the set frequency point from the infrared light emitted by the infrared light source 311, and further analyze the output signal of the infrared detector 309, so as to obtain the content of trans fatty acids in the edible oil and judge whether the edible oil is qualified. The solid substances in the edible oil are separated from the center of the centrifuge barrel 304 by the action of centrifugal force, reducing the influence of the solid substances on the detection data of trans fatty acids in the edible oil during the detection process.

[0027] As Figures 4 - 6 shown, a middle oil extraction mechanism is provided inside the lower housing 2. The middle oil extraction mechanism includes a guide plate 417 fixedly connected to the bottom of the upper housing 1. An inner bracket 412 is slidably sleeved on the surface of the guide plate 417. A rotating column 411 is fixedly connected to the upper surface of the left end of the inner bracket 412. A rubber plug 401 is rotatably connected to the upper surface of the rotating column 411. The rubber plug 401 can block the oil outlet nozzle 413 to control the outflow of the edible oil. The middle part of the lower end of the centrifuge barrel 304 is communicated with the oil outlet nozzle 413. A hydraulic rod 418 is fixedly connected between the inner bracket 412 and the upper housing 1. The hydraulic rod 418 can drive the rubber plug 401 to move up and down to control the opening and closing of the oil outlet nozzle 413.

[0028] Among them, a diversion cover 409 is fixedly sleeved on the upper end of the rotating column 411. Through the diversion cover 409, the amount of edible oil staying on the inner support 412 can be reduced, and the cleanliness of the detection process can be improved. A plurality of diversion rods 410 are fixedly connected to the lower end of the diversion cover 409. Through the diversion rods 410, a guiding effect can be achieved, reducing the probability of edible oil flowing onto the lower surface of the diversion cover 409 and improving the cleanliness of the detection process. The middle part of the inner support 412 is a bent section 419. Through the bent section 419, the amount of edible oil staying on the inner support 412 can be reduced, and the cleanliness of the detection process can be improved.

[0029] Among them, a plurality of oil outlet grooves 402 are formed on the arc surface of the rubber plug 401. Through the oil outlet grooves 402, when the rubber plug 401 moves slightly downward, the edible oil can slowly flow out, preventing the edible oil from flowing out too fast and driving the solid substances to flow out synchronously. A plurality of inserting rods 403 are inserted into the interiors of the plurality of oil outlet grooves 402. Through the inserting rods 403, solid substances can be prevented from falling into the oil outlet grooves 402, resulting in the subsequent solid substances flowing out with the oil outlet grooves 402 and affecting the detection quality. A connecting ring 404 is fixedly connected to the tops of the plurality of inserting rods 403.

[0030] Among them, two support plates 405 are fixedly connected to the surface of the connecting ring 404. A magnet block 406 is fixedly connected to the lower surface of the support plate 405. A support long rod 408 is fixedly connected to the upper surface of the diversion cover 409. A magnet ring 407 is fixedly connected to the top of the support long rod 408. When the magnet ring 407 approaches the magnet block 406, the magnet block 406 can be driven to move downward, so that the inserting rod 403 is inserted into the oil outlet groove 402. A slot 415 is formed on the lower surface of the magnet block 406. A guiding rod 414 is inserted into the interior of the slot 415. The bottom end of the guiding rod 414 is fixedly connected to the inner bottom end of the centrifuge barrel 304. A spring 416 is fixedly connected to the interior of the magnet block 406. Through the spring 416, when the magnet block 406 is out of the attraction range of the magnet ring 407, the inserting rod 403 can be driven to disengage from the oil outlet groove 402. The bottom end of the spring 416 is fixedly connected to the inner bottom end of the centrifuge barrel 304.

[0031] By adopting the above technical solution, after the centrifugal bucket 304 is used to centrifuge the solid substances in the edible oil, the centrifugal bucket 304 continues to rotate. Then, the hydraulic rod 418 is used to drive the rubber plug 401 to move downward until the oil outlet groove 402 is exposed from the oil outlet nozzle 413. At this time, the magnet ring 407 moves away from the magnet block 406, causing the magnet block 406 to fall out of the attraction range of the magnet ring 407, and the spring 416 is in a compressed state. Therefore, the spring 416 can push the magnet block 406 and the insertion rod 403 upward, causing the insertion rod 403 to disengage from the oil outlet groove 402. At this time, the edible oil flows from the oil outlet groove 402 into the oil receiving hopper 305. Since the centrifugal bucket 304 remains in a rotating state at this time, the solid impurities in the edible oil always remain away from the middle of the centrifugal bucket 304 during the outflow process, preventing the solid substances from flowing out along with the edible oil when the centrifugal bucket 304 stops rotating, and preventing the solid substances from affecting the detection result of the trans fatty acids in the edible oil.

[0032] Usage method: First, inject the edible oil into the centrifugal bucket 304, and then drive the centrifugal bucket 304 to rotate through the motor 301, so that the solid substances in the edible oil can be separated from the center of the centrifugal bucket 304 by the action of centrifugal force; Next, the centrifugal bucket 304 continues to rotate. Then, the hydraulic rod 418 is used to drive the rubber plug 401 to move downward, the oil outlet groove 402 is exposed from the oil outlet nozzle 413, and the edible oil flows from the oil outlet groove 402 into the oil receiving hopper 305 and then flows into the detection chamber 308 through the oil delivery pipe 306; Finally, the infrared light source 311 emits infrared light onto the infrared filter 310. The infrared detector 309 receives the infrared light emitted by the infrared light source 311, detects the infrared light at a set frequency point from the infrared light emitted by the infrared light source 311, and further analyzes the output signal of the infrared detector 309 to obtain the content of trans fatty acids in the edible oil.

[0033] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
