Description

Technical Field

[0001] This invention relates to the field of detection technology, and in particular to an online detection system for the uniformity of feed additive premixing and its usage method. Background Technology

[0002] In the field of feed production and processing, the premix uniformity of additives directly determines the nutritional balance and feeding safety of feed products, and is one of the core indicators for measuring feed quality. Whether it is a nutritional additive such as vitamins and minerals, or a functional additive such as drugs and enzymes, its uniform distribution in the basic feed can ensure the stability of the dosage ingested by farmed animals, avoiding toxic side effects caused by excessive local content, or nutritional deficiencies caused by insufficient content. Therefore, accurate detection of premix uniformity is crucial.

[0003] Currently, the testing methods for the uniformity of additive premixing in feed production still mainly rely on the traditional single-point sampling method. This single-point sampling method cannot fully cover the distribution area of ​​materials within the mixer, especially since there are often mixing differences between the center and edges, and between the upper and lower parts of the material flow. Relying solely on the test results of local samples can easily lead to the situation of "misjudging the whole by local uniformity," resulting in unqualified premixed feed flowing into subsequent processes and seriously affecting the stability of product quality.

[0004] Therefore, this invention proposes an online detection system for the premixing uniformity of feed additives and its usage method. Summary of the Invention

[0005] Based on the technical problems existing in the background technology, the present invention proposes an online detection system for the premixing uniformity of feed additives and its usage method.

[0006] The present invention proposes an online detection system for the uniformity of feed additive premixing, comprising a feed additive premixing shell and a feeding port located on the top left side of the feed additive premixing shell. The system is characterized in that a movable base is fixedly installed at the bottom of the feed additive premixing shell, and casters are provided on the bottom side of the movable base. An installation groove is provided at the bottom of the movable base, and a mixing motor is fixedly installed within the installation groove. The output shaft of the mixing motor is fixedly connected to a rotating shaft, and the top end of the rotating shaft rotates through the feed additive premixing shell and is fixedly connected to a stirring paddle.

[0007] A rotary motor is fixedly installed at the top center of the feed additive premix shell. The output end of the rotary motor rotates through the feed additive premix shell and is fixedly connected to a rotating frame. A displacement component is provided on the rotating frame. Two movable frames are movably installed at the bottom of the rotating frame through the displacement component. A lifting component is provided on the movable frame. A lifting frame is movably installed at the bottom of the movable frame through the lifting component. A horizontally arranged sampling frame is fixedly connected to the bottom of the lifting frame. Multiple high-frequency sampling probes for online detection of the uniformity of feed additive premix are fixedly installed at the bottom of the sampling frame.

[0008] The displacement assembly includes a transverse groove at the bottom of the rotating frame, and the top of the moving frame is slidably installed in the transverse groove in the horizontal direction. A transverse lead screw is rotatably installed in the transverse groove, and a lead screw nut is fixedly installed on the moving frame. The transverse lead screw and the lead screw nut are threadedly connected. A mounting shell is fixedly installed at the right end of the rotating frame, and a lead screw motor is fixedly installed inside the mounting shell. The output shaft of the lead screw motor is fixedly connected to the right end of the transverse lead screw.

[0009] Preferably, the lifting assembly includes a mounting cavity on a movable frame, the top of the lifting frame is movably mounted in the mounting cavity, a stepper motor is fixedly mounted in the mounting cavity, a vertical screw is fixedly connected to the output end of the stepper motor, a threaded groove is provided on the top of the lifting frame, and the top of the lifting frame is threadedly connected to the vertical screw through the threaded groove.

[0010] Preferably, a sealing sleeve is fixedly installed on the bottom inner wall of the mounting cavity, and the lifting frame slides vertically through the sealing sleeve.

[0011] Preferably, vertical sliders are fixedly installed on both sides of the lifting frame, and vertical guide rails are installed on both inner walls of the mounting cavity, with the vertical sliders slidingly mounted on the vertical guide rails in the vertical direction.

[0012] Preferably, the transverse lead screw is symmetrically provided with external threads, and the two external threads on the transverse lead screw are arranged in opposite directions.

[0013] Preferably, a horizontal slider is fixedly installed on the top of the lifting frame, and a horizontal guide rail is fixedly installed on the inner wall of the top side of the horizontal groove. The horizontal slider is slidably installed on the horizontal guide rail in the horizontal direction.

[0014] Preferably, a controller is provided on the outside of the feed additive premix shell, and the controller is electrically connected to a rotary motor, a mixing motor, a lead screw motor and a stepper motor respectively.

[0015] Preferably, the online detection system includes a feed additive premix shell, a rotary drive mechanism, a displacement assembly, a lifting assembly, two sampling frames, and multiple high-frequency sampling probes. The rotary drive mechanism includes a rotary motor and a rotary frame. The displacement assembly includes a lead screw motor, a transverse lead screw, and two lead screw nuts. The transverse lead screw has two sections of external threads with opposite directions. The two lead screw nuts are respectively adapted to the two sections of external threads. The lifting assembly includes a stepper motor and a vertical screw. The rotary frame has a movable frame. The lifting frame is connected to the movable frame. The sampling frame is installed at the bottom of the lifting frame. The high-frequency sampling probes are arranged at the bottom of the sampling frame. The usage method includes the following steps:

[0016] S1. Start detection: The controller is used to start the high-frequency sampling probe, and the premixing uniformity of the material in the shell is detected online through multiple high-frequency sampling probes at the bottom of the two sampling frames;

[0017] S2. Rotation to expand the sampling range: Start the rotary motor, which drives the rotary frame to rotate. The rotary frame drives the moving frame, lifting frame, sampling frame and high-frequency sampling probe to rotate synchronously, thereby expanding the radial sampling range of the high-frequency sampling probe;

[0018] S3. Lateral adjustment of sampling position: Start the lead screw motor, which drives the lateral lead screw to rotate forward or backward. Since the two external threads on the lateral lead screw have opposite directions, the two moving frames move in opposite directions on the lateral lead screw through the lead screw nut, so as to move closer or further away from each other. This drives the two lifting frames, sampling frames and high-frequency sampling probe to move closer or further away synchronously. Combined with the rotation action in step S, the lateral sampling area of ​​the high-frequency sampling probe is expanded.

[0019] S4. Vertical adjustment of sampling height: Start the stepper motor, which drives the vertical screw to rotate forward or reverse. The lifting frame moves up and down along the vertical screw through the threaded groove on its surface, driving the sampling frame and the high-frequency sampling probe to move up and down synchronously, adjusting the sampling height of the high-frequency sampling probe, and realizing the sample detection of the upper and lower parts of the material inside the shell;

[0020] S5. Collaborative Detection: Simultaneously execute the actions from step S to step S, causing the high-frequency sampling probe to rotate, move laterally, and rise and fall vertically at the same time, fully covering the center and edge, upper and lower regions of the material flow within the feed additive premix shell, and completing the full detection of the material premix uniformity.

[0021] The beneficial effects of this invention are:

[0022] 1. In this invention, through the three-dimensional coordinated action of rotation, lateral movement, and vertical lifting, the high-frequency sampling probe can better cover the center and edge, upper and lower regions of the material flow inside the premixed shell. This helps to solve the defect of "local uniformity leading to misjudgment of the whole" in traditional single-point sampling, ensuring the representativeness and comprehensiveness of the test samples, and guaranteeing the accuracy of the test results from the source.

[0023] 2. In this invention, a high-frequency sampling probe, combined with three-dimensional dynamic sampling action, enables online continuous detection of the material mixing process. No manual sampling or offline analysis is required, and the detection cycle is greatly shortened compared to traditional methods. It can capture dynamic changes in mixing uniformity in real time, providing timely data support for subsequent control.

[0024] 3. In this invention, the three-dimensional collaborative sampling mode avoids sampling deviations caused by differences in material distribution. Combined with the multi-probe synchronous acquisition design, it effectively reduces the random errors of sampling at a single location. At the same time, the sampling process does not require manual intervention, reducing the contamination or disturbance of samples by human operation and greatly improving the stability of product quality.

A rotary motor 7 is fixedly installed at the top center of the feed additive premix shell 1.

A horizontally arranged sampling frame 11 is fixedly connected to the bottom of the lifting frame 10. Multiple high-frequency sampling probes 12 for online detection of the uniformity of feed additive premixing are fixedly installed at the bottom of the sampling frame 11.

[0034] The displacement assembly includes a transverse groove 801 located at the bottom of the rotating frame 8, and the top of the movable frame 9 is slidably installed in the transverse groove 801 in the horizontal direction. A transverse lead screw 15 is rotatably installed in the transverse groove 801, and a lead screw nut 16 is fixedly installed on the movable frame 9. The transverse lead screw 15 and the lead screw nut 16 are threadedly connected. A mounting shell 13 is fixedly installed at the right end of the rotating frame 8, and a lead screw motor 14 is fixedly installed in the mounting shell 13. The output shaft of the lead screw motor 14 is fixedly connected to the right end of the transverse lead screw 15.

[0035] The lifting assembly includes a mounting cavity 901 on the movable frame 9. The top of the lifting frame 10 is movably mounted in the mounting cavity 901. A stepper motor 902 is fixedly mounted in the mounting cavity 901. A vertical screw 903 is fixedly connected to the output end of the stepper motor 902. A threaded groove 1001 is provided on the top of the lifting frame 10. The top of the lifting frame 10 is threadedly connected to the vertical screw 903 through the threaded groove 1001.

[0036] The installation cavity 901 has a sealing sleeve 906 fixedly installed on the bottom inner wall, and the lifting frame 10 slides through the sealing sleeve 906 in a vertical direction. Vertical sliders 904 are fixedly installed on both sides of the lifting frame 10, and vertical guide rails 905 are installed on both sides of the inner wall of the installation cavity 901. The vertical sliders 904 slide on the vertical guide rails 905 in a vertical direction.

[0037] The transverse lead screw 15 is symmetrically provided with external threads 151, and the two external threads 151 on the transverse lead screw 15 are arranged in opposite directions; the top of the lifting frame 10 is fixedly provided with a transverse slider 802, and the top inner wall of the transverse groove 801 is fixedly provided with a transverse guide rail 803, and the transverse slider 802 is slidably installed on the transverse guide rail 803 in the horizontal direction.

[0038] The feed additive premix shell 1 is equipped with a controller 17 on its exterior. The controller 17 is electrically connected to the rotary motor 7, the mixing motor 5, the lead screw motor 14, and the stepper motor 902.

[0039] A method for using an online detection system for the uniformity of feed additive premixing includes the following steps:

[0040] S1. Start detection: The controller 17 starts the high-frequency sampling probe 12, and the high-frequency sampling probe 12 at the bottom of the two sampling frames 11 performs online detection of the premixing uniformity of the material in the shell;

[0041] S2. Rotation to expand the sampling range: Start the rotary motor 7, the rotary motor 7 drives the rotary frame 8 to rotate, the rotary frame 8 drives the moving frame 9, the lifting frame 10, the sampling frame 11 and the high-frequency sampling probe 12 to rotate synchronously, thereby expanding the radial sampling range of the high-frequency sampling probe 12;

[0042] S3. Lateral adjustment of sampling position: Start the lead screw motor 14, which drives the lateral lead screw 15 to rotate forward or backward. Since the two external threads 151 on the lateral lead screw 15 have opposite thread directions, the two moving frames 9 move in opposite directions on the lateral lead screw 15 through the lead screw nut 16, so as to move closer or further away from each other. This drives the two lifting frames 10, sampling frame 11 and high-frequency sampling probe 12 to move closer or further away synchronously. Combined with the rotation action in step S2, the lateral sampling area of ​​the high-frequency sampling probe 12 is expanded.

[0043] S4. Vertical adjustment of sampling height: Start the stepper motor 902, which drives the vertical screw 903 to rotate forward or reverse. The lifting frame 10 moves up and down along the vertical screw 903 through the threaded groove 1001 on its surface, which drives the sampling frame 11 and the high-frequency sampling probe 12 to move up and down synchronously, thereby adjusting the sampling height of the high-frequency sampling probe 12 and realizing the sample detection of the upper and lower parts of the material inside the shell.

[0044] S5. Collaborative Detection: Simultaneously execute the actions of steps S2 to S4, causing the high-frequency sampling probe 12 to rotate, move laterally, and rise and fall vertically at the same time, fully covering the center and edge, upper and lower areas of the material flow inside the feed additive premix shell 1, and completing the full detection of the material premix uniformity.

[0045] This online detection system for feed additive premix uniformity uses multiple high-frequency sampling probes 12 located at the bottom of two sampling frames 11 to detect the premix uniformity of feed additives within the feed additive premix housing 1. During detection, a rotary motor 7 drives the rotating frame 8, moving frame 9, lifting frame 10, sampling frame 11, and high-frequency sampling probes 12 to rotate as a whole, thus expanding the sampling range of the high-frequency sampling probes 12. Simultaneously, a lead screw motor 14 in the displacement assembly drives the transverse lead screw 15 to rotate forward and backward. Since the two external threads 151 on the transverse lead screw 15 are set in opposite directions, the two moving frames 9 can move closer or further apart via lead screw nuts 16 on the two external threads 151 of the transverse lead screw 15. The movement of the two moving frames 9 also drives the two lifting frames 10, sampling frame 11, and high-frequency sampling probes 12 to move closer or further apart, coordinating with the rotation of the sampling frame 11 and high-frequency sampling probes 12 driven by the rotary motor 7. This design further expands the sampling area of ​​the high-frequency sampling probe 12, ensuring a wider sampling range and enabling thorough and uniform detection of samples at the center and edges of the material flow. Simultaneously, the stepper motor 902 in the lifting assembly drives the vertical screw 903 in both forward and reverse rotation, allowing the lifting frame 10 to move upward or downward along the vertical screw 903 via the threaded groove 1001. The vertical movement of the lifting frame 10 also adjusts the sampling range of the high-frequency sampling probe 12, further enabling detection of samples at the upper and lower parts. Furthermore, the simultaneous rotation, left-right movement, and vertical adjustment of the high-frequency sampling probe 12 ensures thorough and uniform detection of samples at the center and edges, and upper and lower parts of the feed additive premixing uniformity. This avoids the previous situation where a single-point sampling method could not fully cover the material within the mixer, leading to "local uniformity misjudgment of the whole," thus greatly ensuring product quality stability and making it suitable for widespread use.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
