[0002] A near-infrared spectrometer is an analytical device based on the principle of molecular vibration anharmonicity, which uses near-infrared light (wavelength range approximately from 780 nm to 2500 nm) to perform non-destructive and rapid detection on substances. The existing near-infrared spectrometer is directly fixed on the blanking pipe and extends into the interior of the blanking pipe to analyze the powdery medicine powder in the blanking pipe. After long-term use, the lens of the near-infrared spectrometer will be blocked by the accumulated medicine powder, resulting in deviation of its detection results. In addition, the entire spectrometer always spans in the blanking pipe, which will also hinder the blanking speed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The core of the present invention is to provide an automatic cleaning device that can clean the spectrometer lens to ensure the detection accuracy of the near-infrared spectrometer.

[0031] Another core of the present invention is to provide a near-infrared spectrometer detection device including the above automatic cleaning device.

[0032] It should be noted that the orientation or positional relationship indicated by "up", "down", "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0033] An automatic cleaning device provided by the present application includes: a runner 1, a driving component, a cleaning component, and a control system;

[0034] Among them, the runner 1 is rotatably arranged in the blanking pipe 2, and through holes are provided on the runner 1;

[0035] The driving component is fixed to the runner 1, the driving component is connected to the runner 1 and is used to drive the runner 1 to rotate around a fixed axis. The driving component is also connected to the spectrometer lens, and the driving component is used to drive the spectrometer lens to reciprocate in a direction perpendicular to the runner 1 at the through hole;

[0036] The cleaning component is arranged in the blanking pipe 2, and the runner 1 is used to drive the spectrometer lens to move from the blanking pipe 2 to the cleaning component;

[0037] The control system is signal-connected to the driving component and the cleaning component and is used to control the start or stop of the driving component and the cleaning component.

[0038] Specifically, please refer to the attached Figure 1The feeding tube 2 is a tubular passage arranged along the vertical direction, and a through hole is arranged on its side wall, and the through hole is communicated with the inner cavity of the feeding tube 2. Under normal conditions, the near-infrared spectrometer 11 performs non-destructive and rapid detection of the material in the feeding tube 2 through the through hole. After a certain period of use, the spectrometer lens of the near-infrared spectrometer 11 is pulled out of the feeding tube 2 through the driving component until it moves from the first side of the rotating wheel 1 to the second side of the rotating wheel 1. The rotating wheel 1 is a disc-shaped structure with a certain thickness to maintain structural reliability. A through hole is arranged on its surface to penetrate the rotating wheel 1. The driving assembly can drive the spectrometer lens to pass through the through hole to realize the movement of the spectrometer lens. When the spectrometer lens moves to the second side of the rotating wheel 1, the driving assembly drives the rotating wheel 1 to rotate on a fixed axis until the through hole is docked with the cleaning assembly, and then the driving assembly drives the spectrometer lens to pass through the through hole on the rotating wheel 1, so that the spectrometer lens enters the cleaning assembly. The cleaning assembly can clean the spectrometer lens. The whole process is controlled by the control system, which can automatically complete the regular cleaning and maintenance of the spectrometer lens to ensure the accuracy of the detection results of the near-infrared spectrometer 11.

[0039] It should be noted that the control system generally performs timing control on the driving component and the cleaning component, that is, the driving component and the cleaning component are given a designated signal at designated intervals to clean the spectrometer lens in turn to ensure the cleanliness of the spectrometer lens.

[0040] Optionally, an additional detection component can be provided on the cleaning component, and the detection component is used to detect the cleanliness of the spectrometer lens surface. Similarly, the detection component can be replaced by manual observation. When the cleanliness of the spectrometer lens surface is obviously not up to standard, the operator can control the cleaning component to re-clean or repeat the cleaning multiple times through the control system.

[0041] Based on the above embodiment, the driving assembly includes a rotating cylinder 3, the wheel 1 is connected to the rotating cylinder 3, the rotating cylinder 3 is arranged on the side of the wheel 1 away from the driving assembly, the rotating cylinder 3 is connected to the central axis of the wheel 1 and is used to drive the wheel 1 to rotate.

[0042] Specifically, the rotating cylinder 3 is fixed between the feeding pipe 2 and the cleaning component. Generally speaking, the through-hole on the feeding pipe 2 and the entrance of the cleaning component are arranged at the same horizontal height. At this time, every 180° rotation of the wheel 1 can drive the spectrometer lens to switch between the through-hole of the feeding pipe 2 and the entrance of the cleaning component. The output end of the rotating cylinder 3 is fixedly connected to the center point of the wheel 1 to facilitate position adjustment. Setting the rotating cylinder 3 on the side of the wheel 1 facing the feeding pipe 2 can improve the integration of the equipment and reduce the volume.

[0043] Optionally, the rotary cylinder 3 can be arranged on the side of the runner 1 facing away from the blanking pipe 2. However, in this case, a fixing bracket or a fixing wall surface needs to be additionally provided to fix the rotary cylinder 3. This setting can reduce the density of the equipment components, provide sufficient operating space when installing or disassembling the components, and reduce the construction difficulty of the operators.

[0044] Based on the above embodiments, the driving assembly further includes a telescopic cylinder 4. The telescopic cylinder 4 is fixed on the surface of the runner 1, and the output end of the telescopic cylinder 4 is connected to the spectrometer lens.

[0045] Specifically, the telescopic cylinder 4 is arranged on the surface of the runner 1 on the side facing away from the blanking pipe 2. Its fixed end is set on the runner 1, and the direction when its telescopic end extends is the direction away from the blanking pipe 2. The telescopic end of the telescopic cylinder 4 is connected to the near-infrared spectrometer 11 through a fixing plate 12, and the connection between the two is detachable. The telescopic cylinder 4 can drive the near-infrared spectrometer 11 to move along the through hole and in the direction perpendicular to the runner 1. Since the near-infrared spectrometer 11 of the present application is used to detect the substances in the blanking pipe 2, and in order to prevent the substances in the blanking pipe 2 from leaking to the outside of the blanking pipe 2, the outer wall of the near-infrared spectrometer 11 should be completely fitted with the shape and size of the through hole provided on the runner 1 to ensure that after the near-infrared spectrometer 11 passes through the through hole and enters the blanking pipe 2, the inner cavity of the blanking pipe 2 is in a closed state.

[0046] It should be noted that the spectrometer lens in the attached Figure 1 of the present application is also the lens of the near-infrared spectrometer 11. The near-infrared spectrometer 11 can change its position as the telescopic cylinder 4 moves to realize the detection of substances. Figure 2

[0047] Optionally, the telescopic cylinder 4 can be arranged on the side of the runner 1 facing the blanking pipe 2. Correspondingly, a perforation for the output end of the telescopic cylinder 4 to pass through should be additionally provided on the surface of the runner 1. This design can improve the integration of the equipment, but it should be considered that the size of the runner 1 should be relatively large to avoid interference between the telescopic cylinder 4 and other structures during the rotation of the runner 1.

[0048] Based on the above embodiments, the cleaning assembly includes a dust suction box 5 and a blowing assembly. A blowing port 6 is provided on the dust suction box 5, and the blowing port 6 is communicated with the blowing assembly. The blowing assembly is used to blow air into the dust suction box 5.

[0049] Specifically, please refer to the attached Figure 2 ​The dust box 5 is a shell structure with a cavity. An inlet is provided on the surface of the dust box 5. The inlet is preferably at the same horizontal height as the through hole on the feeding pipe 2. The size and shape of the inlet are exactly the same as the through hole on the rotating wheel 1. When the rotating cylinder 3 drives the rotating wheel 1 to rotate, the rotating wheel 1 drives the telescopic cylinder 4 and the near-infrared spectrometer 11 to rotate synchronously. When the through hole on the rotating wheel 1 completely coincides with the inlet on the dust box 5, the rotating wheel 1 stops rotating, and the telescopic cylinder 4 drives the near-infrared spectrometer 11 to move and extend the spectrometer lens into the dust box 5. A blowing port 6 is also provided on the dust box 5. The blowing port 6 is connected to a blowing component (not shown in the figure). The blowing component generally uses a blower. Gas with a certain speed is introduced into the dust box 5 through the blowing component, and the dust on the surface of the spectrometer lens is blown away by the gas to achieve the purpose of cleaning the spectrometer lens.

[0050] On the basis of the above-mentioned embodiment, a dust collection duct interface 7 is further provided on the dust collection box 5 , and the dust collection duct interface 7 is connected to a recovery component, and the recovery component is used to recover the dust in the dust collection box 5 .

[0051] Specifically, a dust collection duct interface 7 is provided on the lower surface of the dust collection box 5, and the dust collection duct interface 7 is connected to a recovery component (not shown in the figure). The air outlet 6 is provided on the side surface of the dust collection box 5 away from the rotating wheel 1. The dust collection duct interface 7 is provided directly below the dust collection box 5. After the spectrometer lens enters from the entrance of the dust collection box 5, it faces the air outlet 6. The gas introduced from the air outlet 6 can directly blow the spectrometer lens to sweep and clean the dust on its surface. Most of the dust is directly blown into the recovery component through the dust collection duct interface 7 along with the gas. Generally speaking, after a certain period of blowing, it is necessary to stop and remain still. Some floating dust will gradually fall into the recovery component through the dust collection duct interface 7 under the action of gravity, so as to prevent the dust from directly escaping into the air and avoid air pollution.

[0052] On the basis of the above embodiment, it further includes a support plate 8, the support plate 8 is fixedly connected to the feeding pipe 2, and the dust collection box 5 is detachably connected to the support plate 8.

[0053] Specifically, the feed pipe 2 is a pipeline formed by splicing multiple sections of pipes end to end, and two adjacent sections of pipes are connected by flanges. A support plate 8 extending from the feed pipe 2 can be set on the flange. The support plate 8 is selected to be an L-shaped structure. The dust box 5 and the rotating cylinder 3 are both fixed on the support plate 8. A plurality of through holes are provided on the support plate 8, so that the dust box 5 and the rotating cylinder 3 can be detachably connected to the support plate 8 by screws and nuts, thereby reducing the difficulty of installation and the difficulty of disassembly required for daily maintenance.

[0054] Based on the above embodiments, at least two extending pipes extending outward are provided on the side wall of the blanking pipe 2. A viewing window 9 is provided on one of the extending pipes, and the inside of the other extending pipe is used to store the spectrometer lens.

[0055] Specifically, the present application also improves the structure of the blanking pipe 2. The existing blanking pipe 2 is directly drilled on the side wall, and the near-infrared spectrometer 11 is inserted into the blanking pipe 2, which will affect the blanking speed of the blanking pipe 2. Based on the existing blanking pipe 2, an extending pipe is connected to the drilling position by means including but not limited to welding. Generally, two extending pipes are provided, and the included angle between the two extending pipes is 180°. A detachable glass viewing window 9 is provided on one of the extending pipes. The operator can directly observe the blanking situation in the blanking pipe 2 and the working state of the near-infrared spectrometer 11, such as whether it is working, through the glass viewing window 9. The other extending pipe is used to store the lens of the near-infrared spectrometer 11. Such a design does not require the near-infrared spectrometer 11 to be directly inserted into the main pipe of the blanking pipe 2 and will not affect the blanking rate in the blanking pipe 2.

[0056] Optionally, the extending pipe occupied by the near-infrared spectrometer 11 extends obliquely upward, effectively preventing the material from flowing towards the runner 1.

[0057] Based on the above embodiments, a sealing ring is provided at the pipe orifice of the extending pipe, and the sealing ring is provided between the extending pipe and the runner 1.

[0058] Specifically, two sealing rings are installed at the outer extending pipe orifice of the blanking pipe 2 and the orifice of the dust suction box 5. The outer one is a lip seal ring, and the inner one is an oil scraping ring. When the near-infrared spectrometer 11 is pushed in, the oil scraping ring holds the near-infrared spectrometer 11 tightly to achieve sealing and prevent dust from overflowing. When the near-infrared spectrometer 11 is withdrawn and rotated, the outer lip of the lip seal ring will be pressed against the surface of the runner 1, and the rotation of the runner 1 can also seal the entire blanking pipe 2 and the dust suction box 5, and no dust will overflow.

[0059] Based on the above embodiments, a switch plate 10 is provided on the blanking pipe 2.

[0060] Specifically, a switch plate 10 can be provided between two adjacent sections of the blanking pipe 2. By controlling the switch plate 10, the accumulation amount of the material in the blanking pipe 2 can be controlled. When the switch plate 10 is closed, the material in the blanking pipe 2 will gradually accumulate upward from the switch plate 10. When the switch plate 10 is in the open state, the material can directly pass through the position where the switch plate 10 is located for blanking.

[0061] In addition, it should be noted that, please refer to the attached Figure 3 and the attached Figure 4, at the lens of the near-infrared spectrometer 11 provided in this application, there is an inclined section, such that the mirror surface forms a specific angle with the lens cylinder, and this angle is the same as the angle formed by the extending pipe of the through-port of the blanking pipe 2 and the vertical direction. The combination of these two same angles makes the mirror surface of the near-infrared spectrometer 11 parallel to the vertical pipe in the blanking pipe 2. In this way, the vertically falling material is not likely to stick to the mirror surface and will not affect the measurement accuracy. Also, it is this angle design that makes the mirror surface in a downward-buckled state when the runner 1 drives the near-infrared spectrometer 11 to the cleaning station. At this time, the material purged from the mirror surface will fly more towards the dust suction pipe interface 7 below, which is more conducive to purging and dust removal.

[0062] In addition to the above automatic cleaning device, the present invention also provides a near-infrared spectrometer detection device including the automatic cleaning device disclosed in the above embodiment. For the structures of other parts of this near-infrared spectrometer detection device, please refer to the prior art and will not be elaborated herein.

[0063] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same and similar parts among the embodiments, reference can be made to each other.

[0064] The above has introduced in detail an automatic cleaning device and a near-infrared spectrometer detection device provided by the present invention. Specific examples are used herein to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
