Description

Technical Field

[0001] This utility model relates to the field of herbicide production technology, specifically to a reaction vessel for metsulfuron-methyl. Background Technology

[0002] Metsulfuron-methyl is a sulfonamide herbicide widely used in agriculture. It boasts advantages such as high efficiency, low toxicity, and low residue, effectively controlling a variety of annual and perennial weeds and playing a vital role in modern agricultural production. The production of metsulfuron-methyl requires a reaction vessel, but existing reaction vessels still have certain shortcomings, such as: The application CN202021155945.8, entitled "A reaction vessel for the production and preparation of herbicides," has a simple stirring structure, stirring only in one direction. This results in uneven mixing of the reactants within the vessel, affecting the uniformity and completeness of the reaction. Consequently, the synthesis yield of mesotrione is unstable, and the product quality is inconsistent, impacting the effectiveness of mesotrione and limiting its application. Therefore, this paper proposes a reaction vessel for mesotrione to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a reaction vessel for metsulfuron-methyl to solve the problem mentioned in the background art that the existing reaction vessels have a simple stirring structure, which affects the mixing of reactants and is not conducive to ensuring the effectiveness of metsulfuron-methyl.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a reaction vessel for metolachlor, comprising a vessel body and a support leg fixedly installed at its bottom; A feed hopper is fixedly installed through the top of the vessel, and a discharge pipe with a valve is fixedly installed through the center of the bottom of the vessel. A stirring rod is fixedly installed through the center of the top of the vessel, and stirring blades are fixedly installed on the surface of the stirring rod, with the stirring blades located inside the vessel.

[0005] The above technical solution facilitates thorough and effective stirring of the reaction materials, ensuring the uniformity and sufficiency of the preparation of mesotrione.

[0006] As a preferred embodiment of this utility model, a box is fixedly installed on the top surface of the vessel body, and a sliding plate is laterally connected to the inner top surface of the box body. A rack is fixedly installed on the bottom surface of the sliding plate, and a gear is meshed with the front side of the rack. The gear is fixedly installed on the surface of the stirring rod.

[0007] By adopting the above technical solution, it is convenient to use the slide to drive the rack to make lateral linear motion. Through the meshing transmission of the rack and gear, the linear motion is converted into the rotational motion of the stirring rod, providing a power transmission path for the stirring rod, so that the stirring rod can rotate stably, thereby realizing the stirring operation of the material in the vessel.

[0008] As a preferred technical solution of this utility model, a motor is fixedly installed on the right inner wall of the box, and a reciprocating lead screw is keyed to the shaft end of the motor. The reciprocating lead screw passes through the slide plate, and the rotation of the reciprocating lead screw is used for the reciprocating linear movement of the slide plate. The left end of the reciprocating lead screw is connected to a bearing on the left inner wall surface of the box.

[0009] By adopting the above technical solution, it is easy for the motor to drive the reciprocating screw to rotate. With the help of the reciprocating screw rotation, the slide plate makes reciprocating linear motion in the box, providing a power source for the reciprocating motion of the rack, realizing the alternating forward and reverse rotation of the stirring rod, changing the traditional single-direction stirring method, and effectively improving the uniformity and fullness of material mixing.

[0010] As a preferred embodiment of this utility model, an air inlet pipe is fixedly installed longitudinally through the top of the box, and the top end of the air inlet pipe is connected to an external chlorine supply device. The bottom end of the air inlet pipe is connected to a gas delivery pipe through a rotary sealing joint, and the gas delivery pipe extends into the interior of the stirring rod. The gas delivery pipe is fixedly connected to the stirring rod. A through pipe is fixedly installed transversely on the gas delivery pipe, and the through pipe is fixedly installed through the outside of the stirring rod. Multiple jet nozzles are evenly and equidistantly arranged at the top and bottom of the through pipe.

[0011] The above technical solution facilitates the external chlorine supply equipment to deliver chlorine to the gas delivery pipe through the inlet pipe. The rotary sealing joint ensures that the gas delivery pipe remains sealed when the stirring rod rotates, preventing chlorine leakage. The chlorine enters the through pipe through the gas delivery pipe and is then evenly sprayed out from multiple nozzles at the top and bottom of the through pipe, allowing the chlorine to be fully distributed inside the reactor body, making full contact and reaction with the materials. This meets the chlorine requirements in the metolachlor production process and improves the efficiency and effectiveness of the reaction.

[0012] As a preferred technical solution of this utility model, the stirring blades are evenly arranged in multiple groups from top to bottom on the surface of the stirring rod, and each group of stirring blades is evenly arranged at equal angles.

[0013] The above technical solution facilitates the equidistant distribution of multiple sets of stirring blades from top to bottom, which can expand the longitudinal range of stirring and ensure that materials at different heights can be effectively stirred. The uniformly set stirring blades at equal angles can form a uniform stirring force field when the stirring rod rotates, ensuring that the materials are uniformly mixed on the cross-section of the reactor body, further improving the uniformity and thoroughness of stirring, which is conducive to the stable progress of the metolachlor synthesis reaction.

[0014] As a preferred technical solution of this utility model, the through pipes are arranged in multiple groups at equal intervals from top to bottom, and each group of through pipes is arranged in multiple groups at equal angles, and the through pipes are staggered with the stirring blades.

[0015] The above technical solution facilitates the equidistant distribution of multiple sets of pipes, allowing chlorine gas to be sprayed evenly in the longitudinal space of the vessel. The equidistant angle of each set of pipes ensures that the chlorine gas is evenly distributed in the cross-sectional direction of the vessel, enabling the chlorine gas to reach all areas of the vessel more smoothly and fully contact the materials.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the reaction vessel for metolachlor can ensure that the material is stirred from different directions and that chlorine gas is introduced to react with the material, ensuring that the material is fully stirred and mixed evenly, improving the reaction efficiency and effect, and ensuring the product quality of metolachlor; The motor drives the reciprocating screw to rotate, which causes the slide plate to move the rack back and forth. In turn, the gear drives the stirring rod to achieve alternating forward and reverse stirring action, which changes the traditional single-direction stirring method. Combined with multiple sets of stirring blades that are evenly spaced from top to bottom and distributed at equal angles, the stirring range is effectively expanded and the uniformity and thoroughness of material mixing are improved. The inlet pipe is connected to the gas delivery pipe extending into the stirring rod via a rotary sealing joint. The through pipe on the gas delivery pipe and the multiple jet nozzles evenly spaced at the top and bottom can evenly distribute chlorine gas into the inside of the reactor. During the rotation of the stirring rod, the gas delivery pipe and through pipe rotate synchronously, so that the chlorine gas can fully contact the material, meet the chlorine gas requirements in the metolachlor production process, and improve the reaction efficiency and effect.

Multiple sets of stirring blades 6 are evenly and equidistantly arranged from top to bottom on the surface of the stirring rod 5, and multiple stirring blades 6 are evenly arranged at equal angles in each set.

[0021] A box 7 is fixedly installed on the top surface of the vessel body 1, and a slide plate 8 is slidably connected to the inner top surface of the box 7. A rack 9 is fixedly installed on the bottom surface of the slide plate 8, and a gear 10 is meshed with the front side of the rack 9. The gear 10 is fixedly installed on the surface of the stirring rod 5.

[0022] A motor 11 is fixedly installed on the right inner wall of the housing 7, and a reciprocating screw 12 is keyed to the shaft end of the motor 11. The reciprocating screw 12 passes through the slide plate 8, and the rotation of the reciprocating screw 12 is used for the reciprocating linear movement of the slide plate 8. The left end of the reciprocating screw 12 is connected to the bearing on the left inner wall surface of the housing 7.

[0023] An air inlet pipe 13 is fixedly installed longitudinally through the top of the housing 7, and the top end of the air inlet pipe 13 is connected to an external chlorine supply device. The bottom end of the air inlet pipe 13 is connected to a gas delivery pipe 15 through a rotary sealing joint 14, and the gas delivery pipe 15 extends into the interior of the stirring rod 5. The gas delivery pipe 15 is fixedly connected to the stirring rod 5.

The slide plate 8 drives the rack 9 to move back and forth. Through the meshing of the rack 9 and the gear 10, the stirring rod 5 rotates alternately in the forward and reverse directions, so that multiple sets of stirring blades 6 rotate synchronously with the stirring rod 5 to fully stir the material in the vessel 1 in multiple directions.
