Description

Technical Field

[0001] This invention relates to the field of pesticide processing equipment technology, specifically to an integrated dimethoate processing reactor. Background Technology

[0002] As is well known, pendimethalin is a selective pre-emergence herbicide widely used in agricultural production. Its finished formulations (such as emulsifiable concentrates and suspension concentrates) require precise mixing, dispersion and preparation of the active ingredient with solvents, emulsifiers, stabilizers and other adjuvants in a finished product reactor.

[0003] For example, patent CN117531455A, published on 2024-02-09, entitled "A Reactor for Pesticide Production," includes a motor, a stirring assembly, a shell, a conveying module, a rotating module and a meshing module, and a top cover. The motor is rotatably mounted on the top cover. The conveying module is connected to the outer wall of the shell. The rotating module is fixedly mounted on the bottom of the motor and rotatably mounted inside the shell. The meshing module is meshed and engaged inside the rotating module. The top cover is fitted and engaged on the top of the shell. The tilting assembly includes a liquid container and a rotating module. The rotating module, through this multi-functional stirring device, stirs the material in the reactor in multiple directions, ensuring that the material is fully and evenly mixed. At the same time, it prevents the material at the bottom of the reactor from settling at the bottom and allows it to mix with the material at the top, thereby ensuring the overall quality of the pesticide. Furthermore, by locking the top cover during the stirring process, it prevents the reactor from being accidentally opened by workers during pesticide stirring, thus affecting the quality of the finished product.

[0004] In the prior art, during the processing of pendimethalin, when the active ingredient and various adjuvants are mixed and reacted in the finished product reactor, a large amount of insoluble substances or byproducts are generated due to chemical reactions, temperature and pressure changes, and impurity reactions during the reaction process. If these insoluble substances are not thoroughly removed, they will directly lead to problems such as layering, precipitation, or clogging of spray equipment in the finished product, seriously affecting product quality and performance. Therefore, the present invention provides an integrated pendimethalin processing reactor. Summary of the Invention

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0024] Please combine Figures 1 to 11As shown, the present invention provides an integrated dimethyl pendimethalin processing reactor, including a reactor body 10 fixedly installed on a support frame, a top cover 11 that can be raised and lowered directly above the reactor body 10, and a lifting mechanism, a filtering mechanism, and a piston plate 30 disposed inside the reactor body 10; the piston plate 30 is driven by the lifting mechanism to push the mixture inside the reactor body 10 in a vertical reciprocating motion, forcing the mixture to circulate inside the reactor body 10 and enter the filtering mechanism for filtration.

[0025] Specifically, the finished product reactor includes a reactor body 10, which is fixedly installed on a frame 20. A top cover 11 is provided on the top of the reactor body 10. A vertical plate 21 is fixedly installed on the frame 20. A movable plate 22 is slidably installed on the vertical plate 21 and is fixedly connected to the top cover 11. A first motor 23 is fixedly installed at the bottom of the vertical plate 21. A first screw 24 is rotatably installed inside the vertical plate 21. The end of the first screw 24 passes through the interior of the movable plate 22 and is threadedly connected to the movable plate 22. The output end of the first motor 23 is fixedly connected to the bottom end of the first screw 24. A piston plate 30 is provided inside the reactor body 10. A second screw 31 is rotatably installed inside the reactor body 10. The end of the second screw 31 passes through the interior of the piston plate 30 and is threadedly connected to the piston plate 30. A fixed plate 13 is fixedly installed inside the reactor body 10. A limit rod 14 is fixedly installed on the fixed plate 13. The end of the limit rod 14 passes through the interior of the piston plate 30 and is slidably connected to the piston plate 30. Additionally, the lifting mechanism includes a second screw 31, a mating sleeve 34 fixedly mounted on the top end of the second screw 31, a second motor 32 fixedly mounted on the top cover 11, a coupling connector 33 fixedly mounted on the output end of the second motor 32, a slot adapted to the coupling connector 33 being provided inside the mating sleeve 34, and multiple protruding teeth 341 fixedly mounted inside the mating sleeve 34. Multiple grooves 331 are provided on the outer surface of the coupling connector 33, and a movable block 35 is slidably disposed in each groove 331, with one end of the movable block 35 near the mating sleeve 34 being set as an inclined surface. A first spring 36 is fixedly mounted between the movable block 35 and the coupling connector 33. In this embodiment, the first motor 23 drives the first screw 24 to advance... During the rotation of the top cover 11 to close the top of the vessel body 10, the connector 33 is inserted into the slot of the docking sleeve 34. When the inclined surface of the movable block 35 contacts the protruding tooth 341, the movable block 35 is completely inserted into the groove 331. After the second motor 32 drives the connector 33 to rotate, when the movable block 35 leaves the area of ​​the protruding tooth 341, the movable block 35 slides out of the groove 331 under the elastic force of the first spring 36. After the side of the movable block 35 contacts the side of the protruding tooth 341, it can drive the second screw 31 to rotate, so that the piston plate 30 rises or falls inside the vessel body 10 to push the mixture inside the vessel body 10, thereby performing the filtration operation.

[0026] Thus, the filtration mechanism is located on the outside of the vessel body 10, and the filtration mechanism includes a closed cylinder 60, which is located on the outside of the vessel body 10. A filter cylinder 63 is fixedly installed inside the closed cylinder 60. A first conduit 61 is fixedly installed at the bottom end of the closed cylinder 60, and one end of the first conduit 61 is fixedly connected to the bottom end of the vessel body 10. A second conduit 62 is fixedly installed at the top end of the closed cylinder 60, and one end of the second conduit 62 is fixedly connected to the vessel body 10. One end of the second conduit 62 is located above the piston plate 30. The other ends of the first conduit 61 and the second conduit 62 are both located inside the filter cylinder 63.

[0027] In this invention, a first through hole 611 is provided at the other end of the first conduit 61, and a first sealing plug 70 is provided at the other end of the first conduit 61. A third channel 623 is provided on the second conduit 62, which is located inside the sealed cylinder 60 and outside the filter cylinder 63. A sealing sleeve 72 is slidably provided on the second conduit 62 and at the third channel 623. A second spring 73 is fixedly installed between the sealing sleeve 72 and the sealed cylinder 60. The first sealing plug 70 is fixedly connected to the sealing sleeve 72 by a first connecting rod 71. A branch pipe 84 is fixedly installed on the first conduit 61. A tapered pipe 85 is fixedly installed on one end of the branch pipe 84. The tapered pipe 85 is located inside the closed cylinder 60 and outside the filter cylinder 63. A tapered plug 82 is provided inside the tapered pipe 85. A second channel 622 is opened on the other end of the second conduit 62. A second sealing plug 80 is provided at the other end of the second conduit 62. The second sealing plug 80 is fixedly connected to the tapered plug 82 through a second connecting rod 81. A third spring 83 is fixedly installed between the second sealing plug 80 and the filter cylinder 63.

[0028] Specifically, after the various raw materials for producing dimethylpentylamine are added into the interior of the reactor body 10, the interior of the reactor body 10 is kept closed. The second screw 31 is driven by the second motor 32 to rotate, causing the piston plate 30 to rise and fall inside the reactor body 10.

[0029] In this embodiment, the piston plate has two motion states: When the piston plate 30 is in an upward motion state, a negative pressure closed space is formed between the bottom of the piston plate 30 and the vessel body 10. At this time, the conical plug 82 in the conical tube 85 moves downward, and the top opening of the conical tube 85 opens. Since the conical plug 82 is fixedly connected to the second sealing plug 80, after the second sealing plug 80 moves downward with the conical plug 82, the multiple second channels 622 on the second conduit 62 open, and the mixture inside the vessel body 10 enters the filter cylinder 63 through the second conduit 62. The filter cylinder 63 then blocks and filters the substances that have not been fully dissolved. The mixture located outside the filter cylinder 63 first enters the conical tube 85, and finally enters the closed space below the piston plate 30 through the first conduit 61. When the piston plate 30 is in a downward motion state, it presses down on the mixture below it. The first sealing plug 70 moves upward under the pressure of the mixture. The mixture enters the filter cylinder 63 through multiple first through holes 611. At the same time as the first sealing plug 70 moves upward, the sealing sleeve 72 also moves upward. At this time, multiple third channels 623 on the second conduit 62 open, and the mixture outside the filter cylinder 63 enters the second conduit 62, and finally enters the area above the piston plate 30 through the second conduit 62.

[0030] Thus, during the above process, the mixture continuously switches between above and below the piston plate 30, each time entering the interior of the filter cylinder 63. All insoluble substances produced during the reaction enter the filter cylinder 63 and do not return to the vessel body 10. The dimethyl pendimethalin mixed in the vessel body 10 does not require filtration and has high quality. Furthermore, the mixture undergoes vigorous movement each time it enters the filter cylinder 63, further facilitating thorough mixing of the various raw materials of dimethyl pendimethalin. A discharge port 12 is fixedly installed at the bottom of the vessel body 10, and a discharge valve is fixedly installed on the discharge port 12. After mixing, the mixture is discharged through the discharge port 12. The bottom of the filter cylinder 63 is inclined, and a drain pipe 631 is fixedly installed at the bottom of the filter cylinder 63. A drain valve is fixedly installed on the drain pipe 631, allowing insoluble substances accumulated at the bottom of the second conduit 62 to be discharged through the drain pipe 631. Example

[0031] In this invention, a large gear 50 is fixedly mounted on the second screw 31, and a small gear 51 is rotatably mounted on the fixed plate 13. The small gear 51 and the large gear 50 are kept in a meshing state. A stirring blade 40 is rotatably mounted on the upper surface of the piston plate 30. The stirring blade 40 is connected to the small gear 51 through a telescopic rod assembly. The telescopic rod assembly consists of a sleeve rod 41, an inner rod 42, and an intermediate rod 43. The bottom end of the sleeve rod 41 is fixedly connected to the stirring blade 40. There is one or more intermediate rods 43, with two adjacent intermediate rods 43 nested together. The outermost intermediate rod 43 is slidably connected to the sleeve rod 41, and the inner rod 42 is slidably connected to the innermost intermediate rod 43. Slide rails 421 are provided on the outer surfaces of both the inner rod 42 and the intermediate rod 43. Limiting sliders 411 that are adapted to the slide rails 421 are fixedly installed on the inner surfaces of both the sleeve rod 41 and the intermediate rod 43.

[0032] During the rise and fall of the piston plate 30, the large gear 50 can drive the small gear 51 to rotate rapidly, and the stirring blades 40 stir and mix the mixture, further improving the rapid mixing of various raw materials for the production of dimethomorph. Example

[0033] In this invention, an annular tube 65 is fixedly installed on the inner surface of the vessel body 10. The annular tube 65 is positioned above the piston plate 30. Multiple drainage holes 651 are evenly spaced along the circumference of the annular tube 65. A connecting tube 64 is fixedly installed on the second conduit 62. The top end of the connecting tube 64 is connected to the interior of the annular tube 65. A second valve 641 is fixedly installed on the bottom end of the connecting tube 64. A first valve 621 is fixedly installed on the top end of the second conduit 62. When the piston plate 30 descends, the first valve 621 closes and the second valve 641 opens. The mixture entering the second conduit 62 then enters the connecting pipe 64, which transports the mixture to the annular pipe 65. Multiple drain holes 651 evenly spray the mixture inside the vessel body 10, allowing the mixture to disperse quickly. The stirring blades 40 further enhance the mixing effect, thereby improving the mixing efficiency of various raw materials for the production of dimethomorph.
