A control valve 14 is provided on the discharge pipe 13.

[0020] For example, the reactor 1 can have a cylindrical or conical structure. The reactor 1 can be mounted on the ground using a profile frame or supported on the ground by support columns 12. The feed pipe 11 can have a straight tube structure or a trumpet-shaped structure. The discharge pipe 13 can have a straight tube structure. The control valve 14 can include, but is not limited to, a solenoid valve or a ball valve.

[0021] For example, referring to Figure 1 Reactor 1 is cylindrical and vertically arranged. Feed pipe 11 is vertically arranged, one end of which is connected to the top of reactor 1. Four support columns 12 are provided, and are evenly arranged along the vertical axis of reactor 1. Support columns 12 are cylindrical and vertically arranged.

[0022] The discharge pipe 13 is a straight tube structure, and the discharge pipe 13 is vertically arranged, and the top end is connected to the bottom end of the reactor 1. The discharge pipe 13 is provided with a solenoid valve.

[0023] According to an example embodiment, referring to Figure 2 and Figure 3 At least one stirring mechanism 3 includes a base member 31, at least one set of stirring teeth 32, a power assembly 33, and a stirring assembly 34. The base member 31 is rotatably disposed within the reactor 1. At least one set of stirring teeth 32 is disposed on the base member 31, and each set of stirring teeth 32 is provided with a plurality of stirring teeth 32. The plurality of stirring teeth 32 are arranged along the radial direction of the rotation circle of the base member 31.

[0024] For example, the base member 31 can be a plate-like or columnar structure. The base member 31 can be made of a corrosion-resistant material, including but not limited to 316L stainless steel, 2205 duplex steel, polytetrafluoroethylene (PTFE) coating, or carbon fiber reinforced resin. The stirring teeth 32 can be provided in multiple groups, and the multiple groups of stirring teeth 32 can be symmetrically arranged on the base member 31.

[0025] Exemplarily, the base member 31 is a rectangular plate-like structure and is vertically arranged, with the width of the base member 31 parallel to the vertical axis of the reactor 1. The base member 31 can be made of 316L stainless steel, and the stirring teeth 32 are provided in two groups, symmetrically arranged at the top and bottom ends of the base member 31. Each group of stirring teeth 32 is provided with multiple stirring teeth, and the multiple stirring teeth 32 are evenly arranged along the length of the base member 31.

[0026] According to an example embodiment, referring to Figure 2 and Figure 3 One end of the power assembly 33 is connected to the base member 31, and the other end contacts the inner wall of the reactor 1. The stirring assembly 34 is rotatably mounted on the base member 31. When the base member 31 rotates, the reactor 1 provides a force to the power assembly 33, causing the power assembly 33 to drive the stirring assembly 34 to rotate, thereby stirring the mixture around the stirring teeth 32, preventing corrosive substances in the mixture from adhering to the stirring teeth 32. The driving mechanism 2 is mounted on the reactor 1 and is used to drive the stirring mechanism 3 to rotate.

[0027] Illustratively, the power assembly 33 is located between the base member 31 and the inner wall of the reactor 1, with one end connected to the base member 31 and the other end in contact with the inner wall of the reactor 1. The stirring assembly 34 is rotatably mounted on the base member 31, and the driving mechanism 2 is mounted on the reactor 1 and is used to drive the stirring mechanism 3 to rotate.

[0028] When the driving mechanism 2 drives the stirring mechanism 3 to rotate, the inner wall of the reactor 1 provides friction for the power component 33, so that the power component 33 drives the stirring component 34 to rotate to stir the mixture around the stirring teeth 32, so that the corrosive substances in the mixture (such as chloride ion-containing sediments) are not easily attached to the stirring teeth 32.

[0029] According to the above embodiment, the driving mechanism 2 drives the stirring mechanism 3 to rotate around the vertical axis of the reactor 1. During the rotation, the base member 31 drives the stirring teeth 32 to stir the mixture, so that the mixture reacts fully to synthesize benzyl alcohol; At the same time, since the power component 33 is in contact with the inner wall of the reactor 1, the inner wall of the reactor 1 provides friction for the power component 33, so that the power component 33 drives the stirring component 34 to rotate to stir the mixture around the stirring teeth 32, so that the corrosive substances in the mixture are not easily attached to the stirring teeth 32, thereby effectively reducing production costs.

[0030] According to an example embodiment, referring to Figure 1 and Figure 4 The drive mechanism 2 includes a driver 21, a driving gear 22, a driven gear 23, and a support cylinder 24. The driver 21 is fixedly connected to the reactor 1; the driving gear 22 is connected to the driver 21, and the driven gear 23 meshes with the driving gear 22. The support cylinder 24 is disposed within the reactor 1 and is coaxially fixedly connected to the driven gear 23. The meshing action of the driving gear 22 and the driven gear 23 causes the support cylinder 24 to rotate.

[0031] For example, the driver 21 may include, but is not limited to, a servo motor, an asynchronous motor, a hydraulic motor, or a pneumatic motor, and the driver 21 may be used in conjunction with a speed reducer. The support cylinder 24 may be made of a corrosion-resistant material, which may include, but is not limited to, 316L stainless steel or 2205 duplex steel.

[0032] Both ends of the support tube 24 can be open, and the two open ends are rotatably connected to the reactor 1 through a limiting groove. A sealing ring can be set in the limiting groove to prevent the mixture from entering the support tube 24; both ends of the support tube 24 can also be sealed, by setting a rotating slot on the support tube 24 and a fixing ring on the reactor 1, and the fixing ring is located in the rotating slot to limit the support tube 24.

[0033] For example, the driver 21 can be a servo motor, fixedly connected to the top of the reactor 1 and located on one side of the feed pipe 11, with the output shaft of the servo motor located within the reactor 1. The driving gear 22 can be connected to the output shaft of the servo motor via a keyway (not shown in the figure).

[0037] Through the above embodiments, the present application increases the number of stirring mechanisms 3. When the support cylinder 24 rotates, the axial arrangement allows the mixture to form spiral convection in the vertical direction, which can avoid stratification; the circumferential uniform distribution can ensure that the reactor 1 is subjected to uniform shear force at each point on the cross section, eliminating the stirring dead zone, thereby improving the stirring effect and further improving the production quality of chlorpyrifos.

The extension member 311 is arranged horizontally, and a vertical plate 312 can be arranged on the extension member 311. One side of the vertical plate 312 contacts the inner wall of the reactor 1.

[0042] According to an example embodiment, referring to Figure 3 At least one roller 331 is coaxially fixedly connected to the vertical rod 330 and contacts the inner wall of the reactor 1. The roller 331 rotates along the inner wall of the reactor 1. The first bevel gear 332 is coaxially fixedly connected to the vertical rod 330.

[0053] According to an example embodiment, referring to Figure 2-Figure 5The production device also includes a detection mechanism 4, which includes an electric telescopic rod 41, a controller 42, a bottom cylinder 43 and a detection component 44. The electric telescopic rod 41 is arranged on the top of the support cylinder 24, the fixed end is fixedly connected to the top of the reactor 1, and the movable end is arranged in the support cylinder 24.

[0054] For example, the fixed connection method between the fixed end of the electric telescopic rod 41 and the top of the reactor 1 may include but is not limited to flange connection or welding.

[0055] Illustratively, the support tube 24 is open at both ends, the fixed end of the electric telescopic rod 41 can be welded to the top center of the reactor 1, the inner wall of the top opening of the support tube 24 can be in contact with the outer wall of the electric telescopic rod 41 through a sealing ring (not shown in the figure), and the movable end of the electric telescopic rod 41 is arranged in the support tube 24.

Specifically, it can be fixed to the sleeve housing of the electric telescopic rod 41 via bolts, and its signal line is led out through a waterproof connector. The controller 42 is located within the sleeve 41. The electric telescopic rod 41 and the driver 21 are both electrically connected to the controller 42. The controller 42 is used to control the extension and retraction of the movable end of the electric telescopic rod 41 and to control the start and stop of the driver 21.

[0058] According to an example embodiment, referring to Figure 2 The top of the bottom cylinder 43 is open and has a rotation groove 431 formed in the open end.

Concentration detection sensor 441 is embedded in a predetermined detection position within support tube 24 and is used to detect the concentration of benzyl alcohol. Concentration detection sensor 441 outputs a concentration signal. Both concentration detection sensor 441 and control valve 14 are electrically connected to controller 42, which responds to the concentration signal output by concentration detection sensor 441.

[0061] For example, it should be noted that the preset detection position is close to the electric telescopic rod 41, which reserves sufficient reaction time for the mixture, and the reaction time is fed back through the height of the support tube 24.

When the concentration of the mixture does not reach the set value, the concentration detection sensor 441 outputs a concentration signal. In response to the concentration signal output by the concentration detection sensor 441, the controller 42 controls the movable end of the electric telescopic rod 41 to move. The movable end of the electric telescopic rod 41 pushes the floating plate 442 to reset. The movable end of the electric telescopic rod 41 contracts and resets. The floating plate 442 squeezes the mixture out of the support cylinder 24, so that the mixture continues to react with the synthetidine. When the concentration of the mixture reaches the set value, the controller 42 controls the solenoid valve to open and remove the chlorpyrifos in the reactor 1. After the pressure is released, the float 442 is reset under the action of its own gravity. This application can easily improve the efficiency of automated production by real-time monitoring of the concentration changes of chlorpyrifos.

[0066] According to an example embodiment, referring to Figure 5 The detection component 44 also includes a float 443, which is fixedly connected to one end of the floating plate 442 away from the electric telescopic rod 41.

[0067] Exemplarily, the float ball 443 is bonded to an end of the float plate 442 away from the electric telescopic rod 41 .

[0068] Through the above embodiments, the present application can enable the float 443 to drive the float plate 442 to displace under the buoyancy of the mixture. By adding the float 443, the buoyancy is increased, making it easier to monitor the concentration change of the herbicide.

[0069] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
