Description

Technical Field

[0001] This utility model relates to the field of pesticide production technology, and specifically to a real-time detection device for pesticide production. Background Technology

[0002] Whether it's a suspension concentrate, emulsifiable concentrate, wettable powder, or water-dispersible granule, thorough and uniform mixing of pesticide materials in a mixing tank is a core step to ensure that pesticide products meet quality standards. After mixing, pesticide materials are usually transferred to large transfer tanks or ton containers for temporary storage.

[0003] Current methods for controlling pesticide product quality typically involve manual sampling by the quality inspection department after pesticides are filled into transit tanks or bulk containers. The collected samples are then transported to a laboratory where they undergo a series of pretreatment processes, professional analytical instrument testing, data processing, and manual review before a quality inspection report for the batch of pesticides is obtained. While this method has relatively low equipment investment costs, it cannot achieve real-time, continuous online monitoring of pesticides, suffers from delayed quality control, lacks tight process control, raises questions about sample representativeness, and is inefficient. Summary of the Invention

[0004] This invention addresses the problems of existing technologies being unable to achieve real-time online continuous detection of pesticides and the problem of detection lag by providing a real-time detection device for pesticide production. This device enables real-time online continuous detection of pesticides and moves the quality detection and monitoring point forward to the completion point of the mixing process. Pesticides can be detected immediately after the pesticide mixture is mixed, thus improving the detection efficiency and production quality.

[0005] To achieve the above objectives, the technical solution of this utility model is: a real-time detection device for pesticide production, comprising a buffer chamber and a detection tube. The upper and lower ends of the buffer chamber are respectively connected to an inlet pipe and an outlet pipe. A conical flow divider corresponding to the outlet pipe is installed inside the buffer chamber, and a flow regulating device is installed on the outlet pipe. The inlet pipe and outlet pipe are respectively connected to a mixing device and the detection tube. The pesticide, after being mixed in the mixing device, enters the buffer chamber through the inlet pipe, and the conical flow divider buffers the pesticide entering the buffer chamber.

[0006] The detection tube is connected to an upper and lower section of the tube at its upper and lower ends, respectively. The upper end of the upper section is connected to the discharge pipe and contains a stirring assembly. The detection tube is composed of several downward-sloping straight tubes connected in sequence, with adjacent tubes tilting in opposite directions. The detection tube is equipped with a thermometer probe, a vibrating densitometer, a vibrating viscometer, and a pH meter. A side window with a near-infrared spectroscopy probe is also provided. Pesticide in the buffer chamber enters the detection tube through the upper section of the tube. The stirring assembly stirs and buffers the pesticide. The thermometer probe measures the real-time temperature of the pesticide liquid. The vibrating densitometer and vibrating viscometer measure the density and viscosity of the pesticide liquid, respectively. The pH meter measures the pH value of the pesticide liquid. The near-infrared spectroscopy probe measures the concentration of the active ingredient and the moisture content of the pesticide liquid.

[0007] Furthermore, the buffer chamber is equipped with an observation window with scale lines, which allows staff to observe the amount of pesticide in the buffer chamber.

[0008] Furthermore, both the upper and lower sections of the tube are inclined downwards, with the upper and lower sections inclined in opposite directions. This is to facilitate the downward flow of pesticides into the detection tube and the transfer tank.

[0009] Furthermore, the stirring assembly includes a drive motor, a rotating shaft, and helical blades. The drive motor is located at the upper end of the upper section of the tube, and its output shaft is connected to the rotating shaft. The rotating shaft is rotatably disposed inside the upper section of the tube, and the helical blades are mounted on the rotating shaft. By using a drive motor to drive the rotating shaft to rotate, the rotating shaft causes the helical blades to rotate within the upper section of the tube, thereby achieving the stirring and buffering effect on the pesticide.

[0010] Furthermore, the detection tube includes a first straight tube, a second straight tube, a third straight tube, and a fourth straight tube connected in sequence, the thermometer probe is disposed on the first straight tube, and the vibrating densitometer and the vibrating viscometer are disposed on the second straight tube.

[0011] Furthermore, the side window is mounted on the third straight tube, and the pH meter is mounted on the fourth straight tube.

[0012] Furthermore, it also includes a control cabinet, which is electrically connected to the flow regulating device, thermometer probe, vibratory densitometer, vibratory viscometer, and pH meter. The control cabinet is used to receive signals and control the device's startup and flow regulation.

[0013] The beneficial effects of this utility model through the above technical solution are as follows: This invention has a reasonable structure and good performance. It can realize real-time online continuous detection of pesticides, and at the same time, it moves the quality detection and monitoring point forward to the completion point of the mixing process. Pesticides can be detected immediately after the pesticide mixture is mixed, thereby significantly shortening the quality feedback cycle, reducing the risk of the entire batch of pesticides being scrapped, and improving the detection efficiency, process controllability and production quality of pesticides.

[0014] In this invention, the buffer chamber plays a role in stabilizing the flow of finished pesticide products, so that the pesticide enters the buffer chamber after being mixed by the equipment and then flows into the detection tube for testing. This avoids damage to the flow regulation device due to the weight and impact of the pesticide. The conical diverter buffers the pesticide entering the buffer chamber. After entering through the feed inlet at the top of the buffer chamber, the pesticide falls into the conical diverter and flows outwards under the action of the conical diverter.

[0015] This utility model uses a buffer chamber to buffer pesticides before conveying them to a detection tube via the upper section of the tube. A thermometer probe measures the real-time temperature of the pesticide liquid, while a vibrating densitometer and vibrating viscometer measure the density and viscosity of the pesticide liquid, respectively. A pH meter measures the pH value of the pesticide liquid, and a near-infrared spectroscopy probe measures the concentration of active ingredients and the moisture content of the pesticide liquid. Real-time online continuous detection of the pesticide is completed as it flows through the detection tube. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-2As shown, a real-time detection device for pesticide production includes a buffer chamber 1 and a detection tube 6. The upper and lower ends of the buffer chamber 1 are respectively connected to an inlet pipe 2 and an outlet pipe 4. The buffer chamber 1 is equipped with a conical diverter 5 corresponding to the outlet pipe 4, and the outlet pipe 4 is equipped with a flow regulating device. In this embodiment, the feed pipe 2 is used to connect to the pesticide mixing equipment. After the pesticide is mixed in the mixing equipment, it can enter the buffer chamber 1 through the feed pipe 2. The buffer chamber 1 is used to stabilize the flow of the pesticide. In the early stage of the pesticide entering the buffer chamber 1, the conical diverter 5 plays a buffering role. After the pesticide enters the buffer chamber 1 through the feed pipe 2, it falls downward onto the conical diverter 5. The conical diverter 5 buffers and diverts the pesticide to make it flow in all directions. The conical diverter 5 includes a conical cover and support columns. Four support columns are installed at the bottom edge of the conical cover. The upper and lower ends of the support columns are connected to the conical cover and the bottom plate of the buffer chamber 1, respectively. The support columns can make a certain gap between the conical cover and the bottom plate of the buffer chamber 1 to ensure that the pesticide can be discharged through the discharge pipe 4.

[0019] The flow regulating device on the discharge pipe 4 plays the role of regulating the flow of pesticide from the buffer chamber 1 into the upper half pipe 12. The flow regulating device adopts the Chinese utility model patent with authorization announcement number CN209651464U, which describes a granule spraying device and a granule spraying flow regulating device.

[0020] The detection tube 6 is connected to an upper section tube 12 and a lower section tube 13 at its upper and lower ends, respectively. The upper end of the upper section tube 12 is connected to the discharge tube 4 and is equipped with a stirring assembly inside. The detection tube 6 is composed of several straight tubes that are inclined downwards and connected in sequence. The inclination directions of two adjacent straight tubes are opposite to facilitate the downward flow of pesticides in the detection tube 6. The detection tube 6 is equipped with a thermometer probe 7, a vibrating densitometer 8, a vibrating viscometer 9, and a pH meter 11. The detection tube 6 is also equipped with a side window 10, on which a near-infrared spectroscopy probe is installed. In this embodiment, the lower half-section pipe 13 is connected to the transfer tank. After the buffer chamber 1 enters the upper half-section pipe 12 from the discharge pipe 4, the stirring assembly stirs and buffers the pesticide entering the upper half-section pipe 12. Then, the pesticide flows downward to the detection tube 6. During the flow of the pesticide in the detection tube 6, the thermometer probe 7 measures the real-time temperature of the pesticide liquid, the vibrating density meter 8 and the vibrating viscometer 9 measure the density and viscosity of the pesticide liquid, respectively, the pH meter 11 measures the pH value of the pesticide liquid, and the near-infrared spectral probe measures the concentration of active ingredients and the moisture content in the pesticide liquid, realizing real-time online continuous detection of the pesticide. The side window 10 is a sapphire lens side window, and the near-infrared spectral probe is a reflective near-infrared spectral probe.

[0021] The buffer chamber 1 is provided with an observation window 3, which has scale lines. In this embodiment, the observation window 3 is made of transparent material, and the observation window 3 and the scale lines thereon facilitate the observation of the amount of pesticide in the buffer chamber 1 by the staff.

[0022] Both the upper section 12 and the lower section 13 are inclined downwards, with the upper section 12 and the lower section 13 inclined in opposite directions. In this embodiment, the downward inclination of the upper section 12 facilitates the downward flow of pesticide into the detection tube 6, and the downward inclination of the lower section 13 facilitates the downward flow of pesticide into the transfer tank.

[0023] The stirring assembly includes a drive motor 14, a rotating shaft 15, and a spiral blade 16. The drive motor 14 is located at the upper end of the upper section tube 12, and its output shaft is connected to the rotating shaft 15. The rotating shaft 15 is rotatably disposed inside the upper section tube 12, and the spiral blade 16 is disposed on the rotating shaft 15. In this embodiment, the rotating shaft 15 is rotatably connected to the upper section tube 12 via bearings. When the drive motor 14 is turned on, its output shaft drives the rotating shaft 15 to rotate, which in turn drives the spiral blade 16 to rotate within the upper section tube 12, thereby stirring and buffering the pesticide being transported within the upper section tube 12.

[0024] The detection tube 6 includes a first straight tube 601, a second straight tube 602, a third straight tube 603, and a fourth straight tube 604 connected in sequence. The thermometer probe 7 is disposed on the first straight tube 601, and the vibrating densitometer 8 and the vibrating viscometer 9 are disposed on the second straight tube 602. In this embodiment, the inclination angles of the first straight tube 601, the second straight tube 602, the third straight tube 603, and the fourth straight tube 604, as well as the upper half-section tube 12 and the lower half-section tube 13, are all 3°. Adjacent straight tubes are connected by flanges to facilitate disassembly and maintenance later.

[0025] The pesticide flows into the first straight pipe 601 through the upper section 12, and then flows sequentially through the first straight pipe 601, the second straight pipe 602, the third straight pipe 603 and the fourth straight pipe 604. During the flow of the pesticide in the first straight pipe 601, the thermometer probe 7 continuously measures the real-time temperature of the pesticide liquid. During the flow of the pesticide in the second straight pipe 602, the vibrating density meter 8 and the vibrating viscometer 9 continuously measure the real-time density and viscosity of the pesticide liquid, respectively.

[0026] The side window 10 is disposed on the third straight pipe 603, and the pH meter 11 is disposed on the fourth straight pipe 604. In this embodiment, during the flow of pesticide in the third straight pipe 603, the near-infrared spectroscopy probe continuously measures the concentration of active ingredients and the water content in the pesticide liquid, and during the flow of pesticide in the fourth straight pipe 604, the pH meter 11 continuously measures the real-time pH value of the pesticide liquid.

[0027] It also includes a control cabinet 17, which is electrically connected to a flow regulating device, a thermometer probe 7, a vibrating densitometer 8, a vibrating viscometer 9, and a pH meter 11. In this embodiment, the control cabinet 17 is also electrically connected to a drive motor 14 to control the drive motor 14. The control cabinet 17 is used to receive signals and control the start-up of the device and flow regulation. The thermometer probe 7, the vibrating densitometer 8, the vibrating viscometer 9, and the pH meter 11 can feed back detection signals to the control cabinet 17.

[0028] The working principle of this utility model is as follows: After the pesticide is mixed in the mixing equipment, it is sent into the buffer chamber 1 through the feed pipe 3. After entering the buffer chamber 1 through the feed pipe 2, the pesticide falls downward onto the conical diverter 5. The conical diverter 5 buffers and diverts the pesticide so that it flows in all directions. By opening the flow regulating device and the drive motor 14 through the control cabinet 17, the pesticide flows into the discharge pipe 4 through the gap between the conical diverter 5 and the bottom plate of the buffer chamber 1. The pesticide enters the upper section pipe 12 through the discharge pipe 4.

[0029] The output shaft of the drive motor 14 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the spiral blades 16 to rotate in the upper section of the tube 12, stirring and buffering the pesticide being transported in the upper section of the tube 12. Then the pesticide flows sequentially through the first straight tube 601, the second straight tube 602, the third straight tube 603, and the fourth straight tube 604. During the flow of the pesticide in the first straight tube 601, the thermometer probe 7 continuously measures the real-time temperature of the pesticide liquid. During the flow of the pesticide in the second straight tube 602, the vibrating densitometer 8 and the vibrating viscometer 9 continuously measure the real-time density and viscosity of the pesticide liquid, respectively. During the flow of the pesticide in the third straight tube 603, the near-infrared spectroscopy probe continuously measures the concentration of active ingredients and the water content in the pesticide liquid. During the flow of the pesticide in the fourth straight tube 604, the pH meter 11 continuously measures the real-time pH value of the pesticide liquid, realizing real-time online continuous detection of the pesticide. Finally, the pesticide flows into the transfer tank for temporary storage through the lower section of the tube 13.

Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
