DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0032] Please refer to Figures 1-3 A finished oil detection device, including upper shell 1 and lower shell 2, the bottom end of the upper shell 1 and the top end of the lower shell 2 are fixedly connected, the separation detection mechanism is arranged in the inside of the upper shell 1 and the lower shell 2, the separation detection mechanism includes the first support 302 fixedly connected to the top end of the upper shell 1, the middle part of the first support 302 is fixedly connected with the motor 301, the centrifugal barrel 304 can be driven to rotate through the motor 301, the output shaft of the motor 301 is fixedly connected with the second support 303, the surface of the second support 303 is fixedly connected with the centrifugal barrel 304, the solid matter in the edible oil can be away from the center of the centrifugal barrel 304 through the rotating centrifugal barrel 304, and the influence of the solid matter on the trans fatty acid detection data in the edible oil in the subsequent detection process is reduced.

[0033] Among them, the inside of the lower shell 2 is fixedly connected with two support rods 307, the two support rods 307 are fixedly connected with the oil receiving hopper 305, the bottom of the oil receiving hopper 305 is communicated with the oil conveying pipe 306, the outlet end of the oil conveying pipe 306 is sleeved with the detection bin 308, the outer circular surface of the oil receiving hopper 305 is fixedly connected with the mounting bracket 312, the lower end of the mounting bracket 312 is mounted with the infrared light source 311, the infrared light source 311 can emit infrared light, the inside bottom end of the lower shell 2 is fixedly connected with the infrared detector 309, the infrared detector 309 can receive the infrared light emitted by the infrared light source 311, and the output signal of the infrared detector 309 is further analyzed.

[0034] The bottom end of the detection bin 308 is fixedly connected with an infrared filter 310. The intake of infrared light can be filtered through the infrared filter 310, and other frequencies of infrared light are filtered out, so as to further improve the accuracy of the detection data of trans fatty acids in edible oil. The lower end of the mounting bracket 312 and the surface of the infrared detector 309 are both fixedly connected with a light shield 315. The light shield 315 can separate the external light source, reduce the interference of the external light source on the detection process, and further improve the accuracy of the detection data of trans fatty acids in edible oil. The outlet end of the oil conveying pipe 306 is fixedly sleeved with a rubber ring 313. The surface of the lower shell 2 is rotatably connected with a shell door 314. When the detection bin 308 is taken out for cleaning, the shell door 314 is opened to take out the detection bin 308 from the oil conveying pipe 306. When the detection bin 308 is installed, the detection bin 308 is fixed through the extrusion force and friction between the rubber ring 313 and the detection bin 308.

[0035] By adopting the above technical scheme, when the edible oil is detected, the edible oil is injected into the centrifugal barrel 304, and then the centrifugal 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 centrifugal barrel 304 by the action of the centrifugal force. Then the edible oil after centrifugal treatment of the solid substances flows into the oil receiving hopper 305 and then flows into the detection bin 308 through the oil conveying pipe 306. At this time, the edible oil is located on the infrared filter 310. When the infrared light source 311 emits infrared light onto the infrared filter 310, the infrared detector 309 can receive the infrared light emitted by the infrared light source 311. The infrared light of the set frequency point is detected from the infrared light emitted by the infrared light source 311, and the output signal of the infrared detector 309 is further analyzed, so as to obtain the content of trans fatty acids in the edible oil, so as to judge whether the edible oil is qualified. The solid substances in the edible oil are separated from the center of the centrifugal barrel 304 by the action of the centrifugal force, so as to reduce the influence of the solid substances on the detection data of trans fatty acids in the edible oil during the detection process.

[0036] As shown in Figures 4-6 The middle oil extraction mechanism is arranged in the inside of the lower shell 2. The middle oil extraction mechanism comprises a guide plate 417 fixedly connected with the bottom of the upper shell 1. The surface of the guide plate 417 is slidably sleeved with an internal support 412. The left end upper surface of the internal support 412 is fixedly connected with a rotating column 411. The upper surface of the rotating column 411 is rotatably connected with a rubber plug 401. The rubber plug 401 can plug the oil outlet nozzle 413, so as to control the outflow of the edible oil. The lower end middle part of the centrifugal barrel 304 is communicated with the oil outlet nozzle 413. The internal support 412 and the upper shell 1 are fixedly connected with a hydraulic rod 418. The hydraulic rod 418 can drive the rubber plug 401 to move up and down, so as to control the opening and closing of the oil outlet nozzle 413.

[0037] The upper end of the rotating column 411 is fixedly sleeved with a flow guide cover 409, which can reduce the amount of edible oil staying on the inner support 412 and improve the cleanliness of the detection process. The lower end of the flow guide cover 409 is fixedly connected with a plurality of flow guide rods 410, which can play a guiding role and reduce the probability of edible oil flowing to the lower surface of the flow guide cover 409, thereby improving the cleanliness of the detection process. The middle part of the inner support 412 is a bending section 419, which can reduce the amount of edible oil flowing to the inner support 412 and improve the cleanliness of the detection process.

[0038] The circular arc surface of the rubber plug 401 is provided with a plurality of oil outlet grooves 402. When the rubber plug 401 moves slightly downward, the edible oil can slowly flow out through the oil outlet grooves 402, preventing the edible oil from flowing out too quickly and driving the solid substances to flow out at the same time. The inner part of each oil outlet groove 402 is inserted with an insertion rod 403, which can prevent solid substances from falling into the oil outlet groove 402 and affecting the detection quality when the solid substances flow out of the oil outlet groove 402. The top end of each insertion rod 403 is fixedly connected with a connecting ring 404.

[0039] The surface of the connecting ring 404 is fixedly connected with two support plates 405. The lower surface of each support plate 405 is fixedly connected with a magnet block 406. The upper surface of the flow guide cover 409 is fixedly connected with a support long rod 408. The top end of the support long rod 408 is fixedly connected with a magnet ring 407. When the magnet ring 407 is close to the magnet block 406, it can drive the magnet block 406 to move downward, so that the insertion rod 403 is inserted into the oil outlet groove 402. The lower surface of the magnet block 406 is provided with an insertion slot 415. The inner part of the insertion slot 415 is inserted with a guide rod 414. The bottom end of the guide rod 414 is fixedly connected with the inner bottom end of the centrifugal barrel 304. The inner part of the magnet block 406 is fixedly connected with a spring 416. When the magnet block 406 is out of the attraction range of the magnet ring 407, the spring 416 can drive the insertion rod 403 to separate from the oil outlet groove 402. The bottom end of the spring 416 is fixedly connected with the inner bottom end of the centrifugal barrel 304.

[0040] By adopting the above technical scheme, after the solid substances in the edible oil are centrifuged by the centrifugal barrel 304, the centrifugal barrel 304 continues to rotate, then the rubber plug 401 is driven downward by the hydraulic rod 418 until the oil outlet groove 402 is exposed from the oil outlet nozzle 413, at this time the magnet ring 407 is away from the magnet block 406, the magnet block 406 is out of the attraction range of the magnet ring 407, and the spring 416 is in a compressed state, so the magnet block 406 and the insertion rod 403 can be pushed upward by the spring 416 to make the insertion rod 403 out of 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 barrel 304 keeps rotating at this time, the solid impurities in the edible oil keep away from the center of the centrifugal barrel 304 during the flowing process, avoiding the solid substances flowing out with the edible oil when the centrifugal barrel 304 stops, preventing the solid substances from affecting the detection result of the trans fatty acids in the edible oil.

[0041] Method for use: first, the edible oil is injected into the centrifugal barrel 304, then the centrifugal barrel 304 is driven to rotate by the motor 301, the solid substances in the edible oil can be away from the center of the centrifugal barrel 304 by the action of centrifugal force;

[0042] Then, the centrifugal barrel 304 continues to rotate, then the rubber plug 401 is driven downward by the hydraulic rod 418, the oil outlet groove 402 is exposed from the oil outlet nozzle 413, the edible oil flows from the oil outlet groove 402 into the oil receiving hopper 305 and then flows into the detection bin 308 through the oil conveying pipe 306;

[0043] Finally, the infrared light source 311 emits infrared light to the infrared filter 310, the infrared detector 309 receives the infrared light emitted by the infrared light source 311, detects the infrared light of the set frequency from the infrared light emitted by the infrared light source 311, and further analyzes the output signal of the infrared detector 309, so as to obtain the content of the trans fatty acids in the edible oil.

[0044] The above is only the preferred specific embodiment of the present application; however, the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme of the present application and the improvement concept thereof within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
