Description

Technical Field

[0001] The present invention relates to the technical field of spectrum detection, and in particular to a spectrum detection device and a detection method and application thereof. Background Art

[0002] In the field of material detection, samples often need to be processed in a complex manner and accurately detected. Traditional detection methods and devices often have some limitations, such as: the sample processing process is cumbersome, and samples need to be transferred between multiple devices, which can easily cause sample loss and contamination; the lack of an integrated design makes it impossible to complete the entire process from sample processing to detection in the same device; for some special samples, such as mangrove leaves, existing detection devices may not meet the needs of rapid on-site detection. Therefore, it is necessary to develop a new type of spectral detection device to solve the above problems. Summary of the invention

[0003] In order to solve the above technical problems, the present application provides a spectrum detection device and a detection method and application thereof.

[0004] In a first aspect, the present invention provides a spectrum detection device, comprising a box and a base arranged at the bottom of the box, on which a material processing module, a liquid adding and oscillating module, a catheter assembly and a spectrum detection instrument are arranged in sequence, wherein:

[0005] The material processing module includes a crushing unit and a current collecting unit. The crushing unit is fixed above the current collecting unit and is fixed to the base through the current collecting unit.

[0006] The liquid adding and shaking module comprises a container sliding mechanism, a liquid adding unit and a shaking slide rail mechanism fixed to a base, the container sliding mechanism is arranged on the shaking slide rail mechanism, and the liquid adding unit is arranged above the moving track of the container sliding mechanism;

[0007] The conduit assembly includes a first delivery pipe and a second delivery pipe, the liquid adding unit is connected to the crushing unit through the first delivery pipe, one end of the second delivery pipe is connected to the current collecting unit, and the other end is arranged above the moving track of the container sliding mechanism;

[0008] The spectrum detection instrument performs spectrum scanning on the liquid to be tested in the container of the container sliding mechanism through the detection port of the box body.

[0009] In the above technical solution, an integrated spectral detection device is realized by sequentially arranging the material processing module, the liquid adding and shaking module, the catheter assembly and the spectral detection instrument on the base. This layout makes the connection between the modules tight and reasonable, reducing the transfer loss and error of the sample during the processing and detection process. The material processing module can perform preliminary processing on the sample to make it suitable for subsequent detection and analysis; the liquid adding and shaking module can accurately add reagents and shake and mix to ensure that the sample and the reagent fully react; the catheter assembly effectively transmits the liquid to ensure the continuity of the whole process; the spectral detection instrument can accurately perform spectral scanning on the treated liquid to be tested, improving the accuracy and reliability of the detection.

[0010] Furthermore, the spectrum detection device also includes a container replenishment module arranged above the moving track of the container sliding mechanism, and the container replenishment module is arranged at the rear end of the liquid adding unit along the moving direction of the container sliding mechanism. The container replenishment module avoids interruption of the detection process due to insufficient containers, thereby improving the detection efficiency. At the same time, the reasonable position arrangement ensures that the container replenishment process does not interfere with the normal operation of other modules, thereby ensuring the stability and reliability of the entire device.

[0011] Furthermore, the container replenishment module includes a material discharge slope, a baffle assembly, and a "J"-shaped channel arranged at the tail of the material discharge slope. The outlet end of the "J"-shaped channel and the baffle assembly are arranged above the moving track of the container sliding mechanism, and the baffle assembly is fixed to the outer side wall of the "J"-shaped channel. The material discharge slope provides an inclined channel to facilitate the container to slide down; the "J"-shaped channel can change the movement direction of the container so that it can accurately reach the top of the moving track of the container sliding mechanism; the baffle assembly can control the falling time of the container to prevent the container from falling too early or too late, thereby ensuring the accuracy and orderliness of the detection process.

[0012] Furthermore, the corners of the material discharge slope and the "J"-shaped channel are rounded and equipped with rubber strips, and the inner wall of the "J"-shaped channel is provided with a groove for guiding the sliding direction of the container. This reduces the collision damage of the container during the sliding process and extends the service life of the container. At the same time, the rubber strip can also play a role in buffering and shock absorption, reducing the noise generated when the container slides down. The groove for guiding the sliding direction of the container on the inner wall of the "J"-shaped channel further improves the accuracy and stability of the container movement, ensuring that the container can reach the designated position accurately.

[0013] Furthermore, the baffle assembly includes a baffle and a second steering gear for controlling the baffle, the second steering gear is fixed to the outer side wall of the "J"-shaped channel, and the baffle is rotatably arranged at the outlet end of the "J"-shaped channel through the second steering gear. By controlling the rotation of the baffle through the second steering gear, the drop of the container can be accurately controlled. The uncertainty and error of manual operation are avoided, and the automation and accuracy of detection are improved.

[0014] Furthermore, the spectrum detection device also includes a wastewater tank that can be drawn out from the back of the box, and the wastewater tank is connected to the current collecting unit through the third delivery pipe of the catheter assembly, and the inlet end of the second delivery pipe is higher than the inlet end of the third delivery pipe. By utilizing the effect of gravity, the supernatant of the sample mixture can be collected preferentially through the second delivery pipe, while the wastewater flows into the wastewater tank through the third delivery pipe, thereby ensuring the reasonable diversion and treatment of the liquid during the detection process.

[0015] Furthermore, the liquid adding unit includes a reactant adding component and a solution injecting component, and the solution injecting component is connected to the crushing unit through a first delivery pipe. The solution injecting component is connected to the crushing unit through the first delivery pipe, so that the solvent can be injected in time during the crushing process, which promotes the crushing and mixing of the sample and improves the efficiency of sample processing.

[0016] Furthermore, the liquid adding unit also includes several water pumps for controlling the addition amount of the reactant adding component and / or the solution injection component. The amount of reagent added can be accurately controlled by the water pump. This precise control can ensure that the sample and the reagent react fully in a predetermined ratio, thereby improving the accuracy and repeatability of the test results. At the same time, the setting of multiple water pumps can meet the requirements of different reagent addition amounts, thereby increasing the adaptability and flexibility of the device.

[0017] Furthermore, the crushing unit includes a wall-breaking cup and a rotating central axis arranged in the wall-breaking cup, a plurality of rotary blades and a chuck, wherein the chuck is sequentially arranged on the rotating central axis at intervals, and the outer ring of the chuck is inlaid with rotary blades. This structural design can effectively crush the sample, and the outer ring of the chuck is inlaid with rotary blades, so that the distribution of the blades is more uniform, and the sample can be crushed in all directions, avoiding the problem of insufficient local crushing.

[0018] Furthermore, the output end of the first delivery tube is higher than the chuck at the top of the rotating middle axis, and the input end of the second delivery tube is lower than the chuck at the bottom of the rotating middle axis. The output end of the first delivery tube is higher than the chuck at the top of the rotating middle axis, so that the injected solvent can fully contact the sample during the crushing process, thereby promoting the crushing and mixing of the sample.

[0019] Furthermore, the rotary blade is an "S" inclined pipeline structure, and the bottom of the wall breaking cup is provided with a conical notch for collecting the precipitated sample mixture. The rotary blade is an "S" inclined pipeline structure, which conforms to the principle of fluid mechanics, reduces the resistance of the blade during rotation, and improves the crushing efficiency.

[0020] Furthermore, the current collecting unit includes a current collecting shell, a first servo and a mid-stream chassis installed on the upper surface of the current collecting shell. The mid-stream chassis is linked to the first servo through a crank rocker and is movably arranged below the wall-breaking cup.

[0021] Furthermore, the side wall and bottom of the current collecting housing are respectively provided with a wastewater outflow outlet and a guide groove, the side wall of the guide groove is provided with a guide port for flowing to the guide groove, and the upper surface of the guide groove is provided with a sealing ring for sealing the bottom of the wall-breaking cup. The provision of the sealing ring ensures the sealing of the bottom of the wall-breaking cup, prevents leakage of the sample mixture, and improves the sealing and reliability of the device.

[0022] Furthermore, the oscillating slide mechanism includes a conveying trough base, a track belt, a slide motor and an oscillator, the slide motor and the oscillator are fixed to the side wall of the conveying trough base, and the upper surface of the conveying trough base is provided with a groove for the track belt and the container sliding mechanism to move. This structural design can provide a stable moving track for the container sliding mechanism and realize the oscillation function.

[0023] Furthermore, the container sliding mechanism includes an integrally formed connection part and a receiving part, the connection part is provided with a through hole for the track belt to pass through, and the cross section of the connection part is an inverted "T"-shaped structure. This structural design enables the container sliding mechanism to be firmly mounted on the track belt and remain stable during movement. The connection part of the inverted "T"-shaped structure can effectively prevent the container sliding mechanism from moving sideways on the track belt, thereby improving the accuracy and stability of container movement.

[0024] Furthermore, a feeding port and a container replenishing port are provided on the upper surface of the box body, and a container taking-out port and a detection port are provided on the side wall of the box body.

[0025] Furthermore, the spectrum detection device also includes a control processing module, which is respectively connected to the spectrum detection instrument, the material processing module, the container supply module and the liquid addition and oscillation module. The control processing module can automatically adjust the operating parameters of each module according to the detection requirements, thereby improving the automation and accuracy of the detection. At the same time, through the communication connection, information can be transmitted between the modules in real time, ensuring the coordination and consistency of the entire detection process.

[0026] In a second aspect, the present invention provides a spectrum detection method, which utilizes a spectrum detection device and specifically comprises the following steps:

[0027] S1. Put the object to be tested into the crushing unit through the feeding port of the box body, use the solution injection components of the crushing unit and the liquid adding unit to crush and inject water to mix the object to be tested, let it stand and settle, and obtain a sample mixed solution;

[0030] S4. Use a spectrum detector to perform spectrum scanning on the liquid to be tested through the detection port of the box.

[0031] In a third aspect, the present invention proposes an application of spectral detection, which uses the detection device described in the first aspect or the spectral detection method described in the second aspect to detect mangrove leaves.

[0032] Furthermore, the spectroscopic detector is a Raman detector, and the reaction liquid added by the reactant adding component in the liquid adding unit is a salt solution and a gold sol.

[0059] In a specific embodiment, reference Figure 1-2 , Figure 6-Figure 1 0, Figure 6 FIG. 7 and FIG. 9 respectively show the structural schematic diagrams of the material processing module, the current collecting unit and the crushing structure of an embodiment of the present invention, FIG. 10 shows the top view and CC direction cross-sectional view of the wall breaking cup of the crushing unit of an embodiment of the present invention. As shown in the figure, the material processing module 300 includes a crushing unit 301 and a current collecting unit 302, the crushing unit 301 includes a wall breaking cup 3011 and a crushing structure arranged in the wall breaking cup 3011, the crushing structure includes a rotating central axis 3013, a plurality of rotary blades 3012 and a chuck 3014, the chuck 3014 is sequentially arranged on the rotating central axis 3013 at intervals, and the outer ring of the chuck 3014 is inlaid with rotary blades 3012. The outer wall of the breaking cup 3011 is provided with an injection port 30112 and a sample liquid outlet 30113 . The injection port 30112 is higher than the top chuck of the rotating central axis 3013 , and the sample liquid outlet 30113 is lower than the bottom chuck of the rotating central axis 3013 and higher than the top of the conical notch 30111 . The collecting unit 302 includes a collecting shell 3024, a first servo 3023 and a mid-stream chassis 3021 installed on the upper surface of the collecting shell 3024. The mid-stream chassis 3021 is linked by a crank rocker 3022 and is movably arranged below the wall-breaking cup 3011. A guide groove 30241 is provided at the bottom of the collecting shell 3024, and a wastewater outlet 30244 is provided on the side wall. A guide port 30243 for flowing to the guide groove 30241 is opened on the side wall of the guide groove 30241. A sealing ring 30242 for sealing the bottom of the wall-breaking cup 3011 is provided on the upper surface of the guide groove 30241. The outer wall of the collecting shell 3024 is also provided with a accommodating cavity 30245 for placing the crushing motor 3015.

[0060] Preferably, combined Figure 8b, the rotary blade 3012 of the crushing structure is an "S"-like inclined assembly line structure. The blades of conventional wall breakers are usually used for larger-sized ingredients such as vegetables and fruits, and the particles after crushing are large and the uniformity is poor. However, since the volume of the object to be tested is relatively small, if a conventional blade is used for crushing, the problem of uneven wall breaking in the upper layer will occur. The special streamlined blade with all-round coverage designed in this application can better realize the process of leaves moving from top to bottom. By designing an S-shaped, inclined streamlined blade, it conforms to the principles of fluid mechanics, thereby reducing more resistance. At the same time, this design also makes it safer and more convenient to clean the crushing unit 301. Since the rotary blade 3012 is long and thick, you only need to pour clean water and start the crushing motor 3015 to complete the cleaning. When the object to be tested is put into the upper chuck, due to the design of the four chucks, the object to be tested is blocked at the top. When the crushing motor 3015 is started to rotate the rotating central shaft 3013, the object to be tested cannot fall directly to the bottom due to the obstruction of the chuck 3014, and can only be carried to the surrounding rotary blades 3012 by the rotation, and then it is initially crushed by the rotary blades 3012, and then falls into the second layer of the chuck, and this cycle is repeated four times until it falls to the bottom. In this process, a more precise crushing operation is achieved, which lays the foundation for the subsequent full reaction detection of the upper clear liquid of the object to be tested.

[0061] Further combined with Figure 9, when the crushing operation is completed, the mixed liquid of the test object is gathered at the conical notch 30111 at the bottom of the wall-breaking cup 3011. The design of the mid-stream chassis 3021 is similar to a piston structure. When the crank rocker 3022 moves to the lowest position, it is tightly connected with the sealing ring 30242, and the drain port is closed; when the crank rocker 3022 reaches the highest position, the mid-stream chassis 3021 moves upward and no longer blocks the drain port. At this time, the mixed liquid of the test object sample flows through its gap, flows through the guide port 30243, and then is collected by the guide groove 30241 and flows out through the wastewater outlet 30244. The specific flow direction is as follows: Fig.9c Shown as red line.

[0062] Further references Figure 1-6, the conveying trough base 4031 has a specific height, and an iron conveying track belt is arranged on the conveying trough base 4031. The right end of the back of this track belt is connected to the slide motor 4033 to provide power to realize transmission, and the conveying track belt is inlaid with the bottom of the container sliding mechanism 401. An oscillator 4034 is arranged on the left side in front of the conveying track belt. When the container sliding mechanism 401 moves on the track according to the liquid adding sequence when conveying the test tube, the oscillator 4034 oscillates the track at a specific frequency during the whole process. Its purpose is not only to promote the full reaction of the reagent, save time and improve accuracy, but also because the conveying trough base 4031 is connected to the base 200, its vibration can be transmitted to the crushing structure of the crushing unit 301, so that the blade residue after internal crushing is shaken off together with the newly added water into the collecting unit 302, and then enters the wastewater tank 800 together, so as to avoid affecting the accuracy of the next round of detection, and also provide convenience for subsequent cleaning operations. By starting the oscillator 4034 and cooperating with the slide rail motor 4033, a suitable frequency can be called to fully oscillate the entire slide rail, thereby achieving a full reaction between the test sample and the reagent, which has the effect of improving accuracy compared to the traditional manual stirring method.

As shown in the figure, the spectrum detection device also includes a container replenishing module 700 arranged above the moving track of the container sliding mechanism 401. Along the moving direction of the container sliding mechanism 401, the container replenishing module 700 is arranged at the rear end of the liquid adding unit 402. The container replenishing module 700 includes a material discharge slope 701, a baffle assembly 703, and a "J"-shaped channel 702 arranged at the tail of the material discharge slope. The container replenishing port 102 is arranged on the upper surface of the box body 100 and is located at the front end of the material discharge slope 701. The outlet end of the "J"-shaped channel 702 and the baffle assembly 703 are arranged above the moving track of the container sliding mechanism 401, and the baffle assembly 703 is fixed to the outer side wall of the "J"-shaped channel 702. The corners of the material discharge slope 701 and the "J"-shaped channel 702 are rounded and provided with silicone strips and / or rubber strips. The baffle assembly 703 includes a baffle 7031 and a second steering gear 7032 for controlling the baffle, the second steering gear 7032 is fixed to the outer side wall of the "J"-shaped channel 702, and the baffle 7031 is rotatably provided at the outlet end of the "J"-shaped channel 702 through the second steering gear 7032.

[0064] Further, combined with Figure 1 , Figure 5 and Fig.12 The inner wall of the "J"-shaped channel 702 is provided with a groove 7021 for guiding the sliding direction of the container 704, and its outer wall is provided with a holder 7022 for installing the second servo 7032 and a support seat 7023 for placing the solution injection assembly 4022. The clamping ring 7041 on the container 704 slides from the entrance end of the "J"-shaped channel 702 to the exit end along the groove 7021 to realize the horizontal to vertical movement direction of the container 704. When the user puts the container 704 (test tube) through the left container supply port 102, with the tube mouth facing the exit of the "J"-shaped channel 702, the test tube will slide down the slope channel. At several collision corners during the sliding process of the test tube, rounded corner design is adopted, and anti-collision rubber protection is added. At the terminal position where the test tube slides down, i.e., the supply outlet of the "J"-shaped channel 702, a second servo 7032 is embedded, and the second servo 7032 is connected to the baffle 7031 of the supply outlet. When the user takes out the first discarded test tube from the container outlet 103 on the left side wall of the box 100, the track belt 4032 operates under the drive of the slide motor 4033 to send the container sliding mechanism 401 without a container back to the bottom of the supply outlet, and then the second servo 7032 immediately controls the baffle 7031 to open. Since the outlet has a slope design, the test tube will naturally slide into the receiving part 4011 of the container sliding mechanism 401, thereby completing a round of supply operation.

[0065] Further, combined with Figure 1-2 9 and 11, the catheter assembly 500 includes a first delivery pipe 501, a second delivery pipe 502 and a third delivery pipe 503. The liquid adding unit 402 is connected to the crushing unit 301 through the first delivery pipe 501. One end of the second delivery pipe 502 is connected to the current collecting unit 302, and the other end is arranged above the moving track of the container sliding mechanism 401. The inlet end of the first delivery pipe 501 is connected to the solution injection assembly 4022, and the outlet end is connected to the injection port 30112 of the wall breaking cup 3011. The input end of the second delivery pipe 502 is connected to the sample liquid outlet 30113 of the wall breaking cup 3011. The spectrum detection device also includes a waste water tank 800 that can be pulled out from the back of the box 100. The waste water tank 800 is connected to the waste water outlet 30244 of the current collecting housing 3024 through the third delivery pipe 503. In the crushing unit 301, water is added to the object to be tested through the solution injection assembly 4022 and the first delivery pipe 501, and after the crushing operation, the upper clear liquid is delivered to the designated location through the second delivery pipe 502 after static treatment, and the remaining liquid is delivered to the waste water tank 800 as waste liquid through the third delivery pipe 503. When the waste liquid in the waste water tank 800 accumulates to a certain volume, the small sliding door at the rear of the overall device can be pulled up to drag the waste water tank 800 out for related processing operations such as dumping.

[0066] In a specific embodiment, the container 704 finally reaches the detection port 104 with the aid of the oscillating slide rail mechanism 403. The user removes the spectrum detector 600 at the back of the device, performs a spectrum scanning operation through the detection port 104, and the detection results are automatically uploaded to the control processing module. After the final scan is completed, the discarded test tubes can be removed through the container removal port 103 by opening the left sliding door.

[0067] Further, the control processing module is respectively connected to the spectrum detection instrument 600, the material processing module 300 and the liquid adding oscillation module 400, wherein the control processing module controls the material crushing process and the waste liquid discharge by controlling the start and stop of the crushing motor 3015 and the first steering gear 3023 of the material processing module 300. The control processing module realizes the transportation, liquid adding and oscillation operation of the object to be tested through the slide motor 4033, the oscillator 4034 and the controller for controlling the start and stop of the water pump. The container 704 is carried by the track belt 4032 driven by the slide motor 4033, and passes under the dripping inlet of the reactant adding component 4021 to perform the liquid adding operation. Then, the oscillator 4034 is started, and cooperated with the slide motor 4033, and a suitable frequency is called to make the entire slide produce sufficient oscillation, so as to promote the detection sample and the reagent to fully react. Compared with the traditional manual stirring method, this method has the effect of improving accuracy. The control processing module controls the controllers of several water pumps of the liquid adding unit 402 to control the addition amount of the reactant adding component 4021 and / or the solution injection component 4022. The addition of water or solvent by the water pump is mainly controlled by its own operating state. With the help of the opening and closing operations of the water pump, the water and specific solvent stored in the reactant adding component 4021 and / or the solution injection component 4022 are added. In terms of precision control, after many experiments and debugging of the controller response rate, the precision can be controlled within 3%, thereby realizing effective control of solvent addition at the software level. For the controller used, the common products with probes on the market can meet the requirements.
