Description

Technical Field

[0001] The invention relates to the technical field of feed additive detection, in particular to a feed additive component detection device. Background Art

[0002] Feed additives are various ingredients added to feed in order to increase the nutritional value of feed, improve the palatability of feed, promote animal growth, prevent and treat animal diseases, etc., such as some trace elements and vitamins. In order to ensure that feed additives do not contain substances that are harmful to humans or animals, such as heavy metals, toxic substances, microbial contamination, etc., it is necessary to test the ingredients of feed additives.

[0003] For example, Chinese patent number CN117269077B discloses a detection device for detecting the composition of feed additives, including: a frame, a top cover is buckled at the upper opening of which, a hopper is fixedly connected to the upper surface of the top cover, a discharge tray and an exhaust pipe are fixedly connected to the side wall of the frame, and a light source is arranged inside the frame; a material guide mechanism is arranged on the bottom surface of the top cover and cooperates with the hopper; a sample preparation mechanism is arranged between the frame and the top cover and is located below the material guide mechanism; a spectrometer is fixedly arranged in the installation opening opened on the upper surface of the top cover and is located directly above the light source.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 11 The present invention provides a technical solution: a feed additive component detection device, comprising a chassis 1, characterized in that: a spectrometer 2 is fixedly installed on the inner bottom surface of the chassis 1, a detection cavity 4 is provided in the chassis 1, a light source 33 is fixedly installed on the inner bottom surface of the detection cavity 4 directly below the spectrometer 2, and a perforation is opened on the top surface of the detection cavity 4;

[0038] The sample preparation part also includes a sample preparation part, which has a light-transmitting surface for laying out the feed additive raw material, and the sample preparation part can lay out the feed additive raw material and prepare samples;

[0039] A feed pipe 9 is also fixedly mounted on the inner wall of the detection cavity 4, and the feed pipe 9 is connected to an external peristaltic pump and can inject fluid and paste-like feed additive raw materials onto the light-transmitting surface.

[0040] When the device is in use, the mixture of the feed additive raw material and the solvent is first dripped onto the surface of the light-transmitting surface through the feed pipe 9 (the mixing method of the feed additive raw material and the solvent can be referred to Chinese Patent No. CN117269077B, and it can be concluded from the document that the feed additive raw material and the solvent are mixed to form a fluid and paste-like sample raw material, so the mixing process is no longer described in detail in this case), and then the mixture is sampled by the sample preparation part, that is, the mixture is smeared into a thin layer with uniform thickness, and then the light source 33 is used to irradiate the light-transmitting surface and the spectrometer 2 is used to perform spectral detection on the sample, so that the flattening sample preparation before the spectral detection of the sample is completed.

[0041] In this way, the mixture of the feed additive raw material and the solvent to be tested is spread out for sample preparation by the sample preparation unit to ensure that the sample to be tested is in a flat and uniform state, so that the error of the spectrometer 2 when testing the sample is reduced to a minimum, thereby improving the accuracy of the analysis result of the spectrometer 2.

[0042] Furthermore, the sample preparation part includes a fixed ring 11 fixedly mounted on the bottom surface of the detection chamber 4, a rotating disk 12 capable of intermittent rotation is mounted on the inner ring of the fixed ring 11, a plurality of through holes are opened on the surface of the rotating disk 12, and a rotating cylinder 32 is rotatably mounted in each through hole, a detection mirror 29 for carrying feed additive raw materials is fixedly mounted on the top surface of the rotating cylinder 32, and a smoothing component for smoothing the sample on the surface of the detection mirror 29 is provided on the side of the rotating disk 12;

[0043] The sample preparation unit also includes a heating component, which is used to heat the detection mirror 29;

[0044] The sample preparation unit also includes a driving unit, which is used to drive the rotating cylinder 32 to rotate and cooperate with the smoothing component to smooth the sample.

[0045] According to the above embodiment, a specific embodiment of a sample preparation part is provided. When the feed pipe 9 drips the mixture of feed additive raw materials and solvent onto the surface of the detection mirror 29, and rotates the rotating cylinder 32 to a suitable position through the rotating disk 12, the driving part drives the rotating cylinder 32 to rotate, and cooperates with the smoothing component to smooth the sample. At the same time, the heating component starts to heat the bottom surface of the detection mirror 29, and transfers the heat to the smoothed sample through the heat conduction of the detection mirror 29. The sample is heated to quickly evaporate the water in the solvent (such as methanol or ethanol, etc.), so that the sample is solidified and shaped into a circular thin sheet with uniform thickness, so as to facilitate the subsequent spectral detection of the sample. Then, the rotating disk 12 continues to rotate to rotate and transport the detection mirror 29 to the bottom of the spectrometer 2 to start spectral detection.

[0046] In this way, the driving unit drives the rotating cylinder 32 to rotate and cooperates with the smoothing component to smooth the sample, and then uses the heating component to remove excess moisture in the sample. The sample can be smoothed into a circular thin slice to facilitate the spectrometer 2 to perform spectral analysis, and the sample to be tested can be shaped and excess moisture can be removed to avoid the presence of moisture affecting some substances with the same wavelength as moisture and causing distortion of the spectral analysis. The shaped sample will not have a reduced center thickness and an increased peripheral thickness due to the action of centrifugal force when the rotating cylinder 32 rotates, thereby affecting the detection mirror 29 of the light source 33 and the penetrability of the sample.

[0047] Furthermore, the smoothing component includes a rotating shaft 13 installed on the bottom surface of the detection chamber 4 and capable of intermittent rotation. The outer wall of the rotating shaft 13 is slidably sleeved with a sliding sleeve 17 through a flat key. The outer wall of the sliding sleeve 17 is fixedly installed with a sliding disk 26 and a cross tool holder 24. Each end of the cross tool holder 24 is provided with a smearing pan 25. Two limit rods 34 are fixedly installed on the bottom surface of the detection chamber 4 on both sides of the rotating shaft 13. The side wall of the sliding disk 26 is provided with a limit groove 27 composed of a plurality of vertical grooves and oblique grooves connected end to end in sequence. The side walls of the two limit rods 34 are fixedly installed with elastic pins that can slide in the limit groove 27. A disc is fixed on the top of the rotating shaft 13, and a spring 23 is provided between the disc and the cross tool holder 24. The bottom surface of the detection chamber 4 is provided with an ultrasonic cleaning machine 15 in which the smearing pan 25 can be immersed.

[0048] According to the above embodiment, a specific embodiment of a smoothing component is provided. Figure 5 When the external mechanism drives the rotating shaft 13 to rotate and drives the sliding sleeve 17 and the sliding disk 26 to rotate together, the elastic pin in the limiting rod 34 slides obliquely upward in the limiting groove 27, causing the sliding disk 26 to slide downward to the bottom. At this time, when the smear pan 25 is located directly above the detection mirror 29, only a certain gap is left between the bottom end of the smear pan 25 and the detection mirror 29. At this time, the driving part drives the rotating cylinder 32 to rotate, which will cause the sample on the upper surface of the detection mirror 29 to be hindered by the smear pan 25, and expand outward to a circular sheet with the rotating cylinder 32 as the center. At the same time, the heating plate 30 aggregates to heat the bottom surface of the detection mirror 29 until the sample is shaped into a hard circular sheet, and the sample preparation can be completed.

[0049] Then, the external structure continues to drive the rotating shaft 13 to rotate, so that the elastic pin in the limiting rod 34 slides downward in the limiting groove 27, and drives the sliding plate 26 to slide downward and slide up to the highest point and then descend. At this time, the next group of smear pans 25 move to the top of the detection mirror 29 to start leveling and preparing the next group of samples, and the previous group of smear pans 25 are immersed in the ultrasonic cleaning machine 15 after two of the above switches, and the ultrasonic cleaning machine 15 is used to clean the samples solidified on the outer wall of the smear pan 25 during the heating process.

[0050] In this way, the sliding sleeve 17 and the cross tool holder 24 are rotated by rotating the rotating shaft 13, the smear pan 25 is switched and cleaned, ensuring that the sample will not adhere to the outer wall of the smear pan 25 and affect the subsequent sample concentration and uniformity. The solidified sample debris may destroy the flatness of the sample surface when the smear pan 25 is smearing the sample, resulting in unevenness or uneven thickness on the sample surface, causing the spectrometer 2 to reduce the accuracy of sample detection. Therefore, switching and cleaning the smear pan 25 can avoid this situation.

[0051] Furthermore, the heating assembly includes a plurality of heating plates 30 slidably mounted on the top surface of a rotating cylinder 32, a sliding tube 28 slidably mounted in the rotating cylinder 32, a spiral groove 31 is provided on the inner wall of the rotating cylinder 32, a limit pin capable of sliding in the spiral groove 31 is provided on the side wall of the sliding tube 28, a long pin is fixedly mounted on the bottom end of the heating plate 30, the long pin can slide in the arc groove provided on the top surface of the sliding tube 28, and the sliding tube 28 does not separate from the long pin when sliding, a magnetic block is provided at the bottom end of the sliding tube 28, and a plurality of magnets 18 corresponding to the magnetic blocks and capable of repelling and attracting the magnetic blocks are fixedly mounted on the bottom surface of the detection chamber 4.

[0052] According to the above embodiment, a specific embodiment of a heating component is provided. When the rotating disk 12 drives the rotating cylinder 32 to move below the magnet 18 attracted to the magnetic block, the magnet 18 attracts the sliding tube 28 to slide downward. When the sliding tube 28 slides downward, the limit pin slides in the spiral groove 31, so that the sliding tube 28 starts to rotate while sliding downward, driving the long pin and the heating plate 30 to slide in the arc groove, gradually opening from a closed state to a diffused state, and stopping heating. Since the heating plate 30 stops sealing the bottom surface of the detection mirror 29 after diffusion, the light source 33 can irradiate the sample on the surface of the detection mirror 29, thereby completing the detection of the sample.

[0053] When the rotating disk 12 drives the rotating cylinder 32 to move below the magnet 18 that repels the magnetic block, the magnet 18 pushes the sliding tube 28 to slide upward. When the sliding tube 28 slides upward, the limit pin slides in the opposite direction in the spiral groove 31, so that the sliding tube 28 starts to rotate while sliding upward, driving the long pin and the heating plate 30 to slide in the arc groove, gradually closing from a diffused state to form a circular disk and starting to heat with electricity. At this time, the rotating cylinder 32 rotates and cooperates with the smear pan 25 to evenly spread the sample, and heats the sample through the heating plate 30 to remove water and solidify it, completing the flattening and shaping of the sample.

[0054] Furthermore, the driving part includes a motor 3 fixedly mounted on the bottom surface of the chassis 1, the part of the main shaft of the motor 3 that penetrates into the detection cavity 4 is fixedly connected to the central axis 5, the outer wall of the central axis 5 is fixedly mounted with a driving gear 7, the outer wall of the bottom end of the rotating cylinder 32 is fixed with a transmission gear 20, and the bottom surface of the detection cavity 4 is rotatably mounted with a transmission gear 19 that can mesh with the driving gear 7 and the transmission gear 20 at the same time.

[0055] According to the above embodiment, a specific embodiment of a driving unit is provided. Figure 4 When the motor 3 drives the central shaft 5 and the driving gear 7 to rotate together, it will drive the transmission gear 19 and the transmission gear 20 to rotate together, that is, drive the rotating cylinder 32 to start rotating, and the driving of the rotating cylinder 32 to rotate as mentioned above can be completed.

[0056] Furthermore, a cross groove 16 is formed on the bottom surface of the rotating disk 12 , a rotating plate 21 is fixedly mounted on the top of the central axis 5 , and a limiting block 22 that slides in the cross groove 16 is fixedly mounted on one end of the rotating plate 21 .

[0057] According to the above embodiment, a specific embodiment of driving the rotating disk 12 to rotate intermittently is provided. Figure 4 When the motor 3 drives the central shaft 5 and the rotating plate 21 to rotate together, the limit block 22 can be driven to rotate and drive the rotating disk 12 to rotate intermittently.

[0058] Furthermore, a rotating shaft is fixedly installed at the center of the cross groove 16, a first pulley 6 is fixedly installed at the bottom end of the rotating shaft, a second pulley 14 is fixedly installed on the outer wall of the rotating shaft 13, and the first pulley 6 and the second pulley 14 are connected by belt transmission.

[0059] In this embodiment, each rotation of the central axis 5 and the rotating plate 21 will cause the rotating disk 12 to rotate ninety degrees, and because the transmission ratios of the first pulley 6 and the second pulley 14 are consistent, the rotating disk 12 rotates ninety degrees and the rotating shaft 13 rotates ninety degrees at the same time, that is, while the rotating disk 12 rotates and switches the sample, the rotating shaft 13 also switches the smear pan 25 once, ensuring that the smear pan 25 corresponding to each sample is unused or cleaned when it is flattened for sample preparation, so as to avoid contamination or influence of other samples on the sample, thereby causing distortion of the test result.

[0060] Furthermore, a scraping plate 10 is fixedly installed on the inner wall of the detection chamber 4, and an air outlet connected to the external air supply pipeline is provided above the scraping plate 10. A liquid outlet pipe 8 connected to the external liquid supply equipment is also fixedly installed on the inner wall of the detection chamber 4. An electromagnetic valve is provided at the mouth of the liquid outlet pipe 8, and a waste recovery area is provided on the bottom surface of the detection chamber 4 below the scraping plate 10.

[0061] According to the above embodiment, when the rotating disk 12 rotates intermittently to rotate the tested sample to the bottom of the liquid outlet pipe 8, a certain amount of cleaning liquid is dripped onto the surface of the detection mirror 29 through the control of the solenoid valve to soften the sample after heating and curing. Then the rotating disk 12 drives the sample to continue to rotate to the scraping plate 10. When passing through the scraping plate 10, the sample will be scraped off the surface of the detection mirror 29, and the sample and excess cleaning liquid will be blown to the waste recovery area below the scraping plate 10 through the air outlet, completing the cleaning work of the surface of the detection mirror 29 passing through this area.

[0062] It is worth mentioning that since four detection mirrors 29 are provided on the rotating disk 12, Fig.11As shown, a is the detection area, b is the cleaning area, c is the preheating area, and d is the sample preparation area. When the detection mirror 29 rotates to the b area, in order to prevent the cleaning liquid from being retained on the surface of the detection mirror 29 and entering the d area, which causes contamination of the sample, a magnet 18 that repels the magnetic block can be set at the bottom of the c area, so that the heating plate 30 completes polymerization and starts to heat the detection mirror 29, thereby evaporating the retained cleaning liquid and avoiding the cleaning liquid from affecting the concentration or absorbance of the sample. In addition, by preheating the detection mirror 29 at c, the detection mirror 29 can evaporate excess water in the sample faster when it enters the d area, so that the sample can be quickly shaped and the centrifugal force when the rotating cylinder 32 rotates can be avoided from throwing the sample out.

[0063] Furthermore, a differential is provided between the transmission gear 19 and the drive gear 20 so that the drive gear 20 rotates at least 360 degrees when the transmission gear 19 rotates 90 degrees.

[0064] According to the above embodiment, in order to ensure the uniformity of the thickness of the sample when it is flattened, the transmission ratio between the transmission gear 19 and the transmission gear 20 should be set to at least 1:4, that is, the transmission gear 20 can rotate at least 360 degrees when the transmission gear 19 rotates 90 degrees, or the transmission gear 20 can rotate a multiple of 360 degrees when the transmission gear 19 rotates 90 degrees through the differential.

[0065] Furthermore, an arc-shaped plate that can fit with the plane where the detection mirror 29 is located is fixed to one end of the smear pan 25.

[0066] According to the above embodiment, since the smear pan 25 may concentrate certain samples on the outer circle of the detection mirror 29 when smoothing the samples, an arc-shaped plate that can fit with the plane of the detection mirror 29 is fixed at one end of the smear pan 25 to prevent the samples from being squeezed out of the detection range of the detection mirror 29 when the rotating cylinder 32 rotates.

[0067] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
