Description

Technical Field

[0001] The invention relates to the technical field of pesticide preparation, and in particular to a pesticide preparation device containing cyhalofop-butyl and zinc sulfate and a preparation method thereof. Background Art

[0002] Cyhalofop-butyl is mainly used to control grass weeds in rice fields, such as barnyard grass, chinensis, and crabgrass, which pose a serious threat to the growth of rice. Cyhalofop-butyl has a highly effective control effect on these weeds and is highly safe for rice. It will not cause phytotoxicity when used from the seedling stage to the jointing stage. The application of zinc sulfate in pesticides is mainly reflected in its use as a trace element fertilizer and its specific control function. Therefore, some pesticides containing cyhalofop-butyl and zinc sulfate are available on the market. The pesticide preparation process mainly involves mixing cyhalofop-butyl and zinc sulfate to prepare the finished product.

[0003] After searching, the Chinese patent (Announcement No.: CN116474675B) disclosed "a high-purity pesticide powder preparation device, including a preparation barrel, a feeding mechanism installed on the preparation barrel, a servo motor and a carrying plate fixedly installed in the preparation barrel, and a driving spindle rotatably installed between the driving end of the servo motor and the carrying plate, a plurality of stirring blades fixedly installed on the driving spindle, a partition plate fixedly installed in the preparation barrel, and an impurity removal mechanism installed between the partition plate and the preparation barrel, a processing barrel fixedly installed in the preparation barrel, and a liquid guide tube fixedly installed between the processing barrel and the partition plate, a fixed plate fixedly installed in the processing barrel, a plurality of heating plates located above the fixed plate fixedly installed in the processing barrel, a liquid guide mechanism installed between the preparation barrel and the processing barrel, the liquid guide mechanism including a storage ring fixedly installed in the preparation barrel, a plurality of water guide pipes fixedly installed between the storage ring and the processing barrel, a barrier net disk fixedly installed in the inlet end of each water guide pipe, and a plurality of liquid discharge pipes fixedly installed between the storage ring and the preparation barrel";

[0004] However, in the process of implementing the relevant technology, this type of patent has certain technical defects. Among them, the above patent adopts the method of filtering precipitation to remove impurities and heating evaporation to remove water to quickly remove impurities in the liquid medicine. However, this method is not suitable for the preparation of pesticides containing cyhalofop-butyl and zinc sulfate. Since cyhalofop-butyl is a chiral compound, only the (R)-enantiomer has biological activity. However, in the current synthesis process, it is difficult to synthesize the biologically active (R)-isomer with high selectivity, resulting in the product often containing a certain amount of (S)-isomer or other impurities. These impurities may affect the biological activity and environmental friendliness of cyhalofop-butyl and reduce its use effect.

The separation mechanism 10 comprises a distillation tank 101 fixedly connected to the inner side of the shell 2, a feed pipe 102 connected with the bellows 8 is fixedly connected to the top of the distillation tank 101, and a solenoid valve 9 is fixedly connected to the feed pipe 102. A heating element for heating cyhalofop-butyl is arranged on the inner side of the distillation tank 101, a steam conduit 106 is fixedly connected to one end of the distillation tank 101, and a condensation mechanism 11 is arranged at the outlet end of the steam conduit 106, and a mixing mechanism 12 for mixing cyhalofop-butyl with zinc sulfate is arranged at the outlet end of the condensation mechanism 11.

[0034] The cyhalofop-butyl mixture is heated at different temperatures by a heating element, and distilled and separated according to the different boiling points of cyhalofop-butyl and isomers. The separated cyhalofop-butyl and isomer vapor are then introduced into the condensing mechanism 11 through the steam conduit 106 for sequential condensation. Finally, the liquid cyhalofop-butyl is introduced into the mixing mechanism and mixed with zinc sulfate to obtain a finished product. The whole process can achieve the separation of cyhalofop-butyl and isomers, and effectively avoid the problem of reduced use effect of cyhalofop-butyl caused by isomers.

[0035] Furthermore, the heating element includes a concentrically arranged heating tube 1 103, a heating tube 2 104, and a heating tube 3 105, and the heating tube 1 103, the heating tube 2 104, and the heating tube 3 105 are all fixedly connected to the inner side of the distillation tank 101, and the diameters of the heating tube 1 103, the heating tube 2 104, and the heating tube 3 105 decrease successively, and the power of the heating tube 1 103, the heating tube 2 104, and the heating tube 3 105 decreases successively, and a temperature sensor 107 is fixedly connected to the inner side of the distillation tank 101, and a temperature controller 13 is fixedly connected to the outer side of the shell 2, and the temperature sensor 107 is signal-connected to the temperature controller 13, and the heating tube 1 103, the heating tube 2 104, and the heating tube 3 105 are all electrically connected to the temperature controller 13.

Since the boiling points of cyhalofop-butyl and the isomers are different, cyhalofop-butyl and the isomers are distilled and separated at different boiling points, thereby achieving the effect of removing the isomers in cyhalofop-butyl, further improving the purity of cyhalofop-butyl, and also improving the use effect of cyhalofop-butyl.

[0037] Furthermore, the condensing mechanism 11 includes a condenser 111 connected to the outlet end of the steam conduit 106, the outlet end of the condenser 111 is fixedly connected with a liquid outlet pipe 112, the outlet end of the liquid outlet pipe 112 is fixedly connected with a three-way pipe 113, one end of the three-way pipe 113 is fixedly connected with a discharge pipe 114 for discharging isomers, the other end of the three-way pipe 113 is fixedly connected with a feed pipe 115 for delivering cyfluthrin, and the discharge pipe 114 and the feed pipe 115 are both fixedly connected with a solenoid valve 116 for controlling the opening and closing of the pipeline.

[0038] The vaporized product of cyhalofop-butyl or isomers is introduced into the condenser 111 through the steam conduit 106 for condensation to form a liquid product, and the liquid product of the isomers is discharged through the impurity discharge pipe 114, while the feeding pipe 115 can introduce the liquid product of cyhalofop-butyl into the mixing mechanism 12 to mix with zinc sulfate, thereby realizing the preparation of high-purity cyhalofop-butyl and zinc sulfate pesticide products, which greatly improves the use effect of the pesticide products. Example

[0039] In the first embodiment, the cyhalofop-butyl mixture is heated to become a vapor, and the vapor contains a large amount of heat energy. If the vapor is directly condensed into a liquid, it will not only cause a waste of heat energy, but also require a large amount of cooling medium, thereby causing a waste of energy. In view of this, another preferred embodiment of the present invention is proposed;

[0040] like Figure 6~Figure 7 As shown in the figure, as another preferred embodiment of the present invention, the only difference from the first embodiment is that the mixing mechanism 12 includes a mixing barrel 121 fixedly connected to the top of the base 1, one end of the top of the mixing barrel 121 is fixedly connected to a feeding pipe 122 for introducing zinc sulfate, one end of the mixing barrel 121 is connected to the outlet end of the feeding pipe 115, the bottom of the mixing barrel 121 is fixedly connected to a discharge pipe 123, the inner side of the mixing barrel 121 is rotatably connected to a stirring shaft 124, the outer side of the stirring shaft 124 is fixedly connected to a plurality of evenly distributed stirring rods 125, and the steam conduit 106 is provided with a stirring rod 124 that is connected to the mixing barrel 121 by coordinating the flow of steam to The pneumatic part 126 drives the stirring shaft 124 to rotate, and the pneumatic part 126 includes a sealing cylinder 1261 fixedly connected to the steam duct 106, the inner side of the sealing cylinder 1261 is rotatably connected to a steam impeller 1262, the steam impeller 1262 is coaxially fixedly connected to a bevel gear 1263, the inner side of the sealing cylinder 1261 is rotatably connected to a bevel gear 1264 meshing with the bevel gear 1263, the bevel gear 1264 is coaxially fixedly connected to a pulley 1265, the top end of the stirring shaft 124 is fixedly connected to a pulley 2 1266, and the pulley 2 1266 is connected to the pulley 1 1265 through a belt drive.

[0041] The vapor of cyhalofop-butyl or its isomers is introduced into the sealing cylinder 1261 through the steam conduit 106, and the high-pressure vapor will drive the steam impeller 1262 to rotate, and then be introduced into the condenser 111 from the outlet end of the sealing cylinder 1261 for condensation to form a liquid, and the liquid of the isomers is discharged through the discharge pipe 114, while the feeding pipe 115 can introduce the liquid of cyhalofop-butyl into the mixing cylinder 121 to mix with zinc sulfate. During the rotation of the steam impeller 1262, the bevel gear 1263 will be driven to rotate, so that the bevel gear 1264 drives the pulley 1265 to rotate synchronously, and the pulley 2 1266 drives the stirring shaft 124 to rotate, so that all the stirring rods 125 rotate circumferentially, so that the liquid of cyhalofop-butyl and the zinc sulfate are fully mixed, which can not only realize the full utilization of the heat energy of the vapor of cyhalofop-butyl or its isomers, but also improve the mixing effect of the finished cyhalofop-butyl and zinc sulfate pesticide products. Example

[0042] like Figure 8~Figure 10As shown, as another preferred embodiment of the present invention, the only difference from the first or second embodiment is that the stirring mechanism 6 includes a plurality of stirring blades 61 equidistantly distributed along the vertical direction, the plurality of stirring blades 61 are fixedly connected to the central shaft 5, the top of the central shaft 5 is fixedly connected to a rotating frame 62, the outer edge of the rotating frame 62 is rotatably connected to a plurality of rotating shafts 63 equiangularly distributed around the rotating frame 62, a plurality of stirring blades 64 staggered with the stirring blades 61 are fixedly connected to the plurality of rotating shafts 63, the tops of the plurality of rotating shafts 63 are fixedly connected to movable gears 65, the top wall inside the housing 2 is fixedly connected to a fixed gear 66, and the plurality of movable gears 65 are meshed with the fixed gear 66;

[0043] By starting the motor 4, the central shaft 5 rotates, so that all the stirring blades 1 61 rotate circumferentially. At the same time, the rotating frame 62 drives all the rotating shafts 63 to move circumferentially, so that all the movable gears 65 roll along the fixed gear 66, which makes all the rotating shafts 63 rotate synchronously, and all the stirring blades 2 64 rotate, so that the stirring blades 2 64 and the stirring blades 1 61 stir the cyhalofop-butyl raw material at the same time, so that the cyhalofop-butyl raw material is fully mixed and reacted, thereby greatly reducing the content of cyhalofop-butyl isomers.

[0044] Furthermore, the screening mechanism 7 includes a mounting frame 71 slidably connected to the inner side of the housing 2, a plurality of slide bars 73 equiangularly distributed around the mounting frame 71 are fixedly connected to the outer edge of the bottom of the mounting frame 71, a plurality of fixed plates 72 slidably connected to the corresponding slide bars 73 are fixedly connected to the inner wall of the housing 2, a plurality of springs 74 are sleeved on the plurality of slide bars 73, the top ends of the plurality of springs 74 are in contact with the mounting frame 71, the bottom ends of the plurality of springs 74 are in contact with the corresponding fixed plates 72, a sieve plate 75 is fixedly connected to the inner side of the mounting frame 71, and a plurality of springs 74 are fixedly connected to the bottom of the mounting frame 71. The guide hopper 77 and the sieve plate 75 are provided with a pushing member 76 at the center position thereof for driving the sieve plate 75 to move downward intermittently by cooperating with the rotation of the central shaft 5. The pushing member 76 includes a mounting plate 761 fixedly connected to the center position of the sieve plate 75, a plurality of arc-surface pressure blocks 762 equiangularly distributed around the mounting plate 761 are fixedly connected to the top of the mounting plate 761, a rotating plate 763 is fixedly connected to the bottom of the central shaft 5, an arc-surface top block 764 is fixedly connected to one end of the bottom of the rotating plate 763, and the arc-surface top block 764 intermittently conflicts with any one of the arc-surface pressure blocks 762 by cooperating with the rotation of the central shaft 5.

[0045] By starting the motor 4 to rotate the central shaft 5, the rotating plate 763 drives the arc surface top block 764 to rotate. When the arc surface top block 764 contacts one of the arc surface pressing blocks 762, the arc surface pressing block 762 is squeezed and moves downward, which makes the screen plate 75 drive the mounting frame 71 to move downward, so that all the springs 74 are compressed and accumulate potential energy.

[0046] When the arc top block 764 is separated from the arc pressure block 762, all the springs 74 release their potential energy, so that the mounting frame 71 drives the sieve plate 75 to move upward, and the sieve plate 75 can vibrate up and down in this cycle, so that the impurities after the reaction of the cyhalofop-butyl raw material can be removed. At the same time, the vibration screening method can avoid the problem of sieve hole blockage.

[0047] The present invention also provides a method for preparing a pesticide containing cyhalofop-butyl and zinc sulfate, which is implemented according to a pesticide preparation device containing cyhalofop-butyl and zinc sulfate, and comprises the following steps: S1: First, the cyhalofop-butyl raw material is introduced into the housing 2 through the feed pipe 3 for mixing reaction, and then the motor 4 is started to drive the central shaft 5 to rotate, so that all the stirring blades 1 61 rotate circumferentially, and at the same time, the rotating frame 62 drives all the rotating shafts 63 to move circumferentially, so that all the movable gears 65 roll along the fixed gear 66, so that all the rotating shafts 63 rotate synchronously, and all the stirring blades 2 64 rotate, so that the stirring blades 2 64 and the stirring blades 1 61 stir the cyhalofop-butyl raw material at the same time, so that the cyhalofop-butyl raw material is fully mixed and reacted, and the content of cyhalofop-butyl isomers is greatly reduced; S2: The rotation of the central shaft 5 causes the rotating plate 763 to drive the arc surface top block 764 to rotate. When the arc surface top block 764 contacts one of the arc surface pressing blocks 762, the arc surface pressing block 762 is squeezed and moves downward, which causes the sieve plate 75 to drive the mounting frame 71 to move downward, so that all the springs 74 are compressed and accumulate potential energy; when the arc surface top block 764 is separated from the arc surface pressing block 762, all the springs 74 release potential energy, so that the mounting frame 71 drives the sieve plate 75 to move upward, and the cycle continues. The sieve plate 75 can reciprocate up and down, so that the impurities after the reaction of the cyhalofop-butyl raw material can be removed, and then the solenoid valve 9 is opened to allow the bellows 8 to introduce the cyhalofop-butyl mixture into the distillation tank 101; S3: The temperature inside the distillation tank 101 can be detected in real time by the temperature sensor 107, and then the temperature controller 13 controls the heating tube 103, the heating tube 2 104, and the heating tube 3 105 to work individually or synchronously to achieve the temperature control effect, so that the cyhalofop-butyl mixture inside the distillation tank 101 can be heated at different temperatures. Since the boiling points of cyhalofop-butyl and the isomers are different, the cyhalofop-butyl and the isomers are distilled and separated at different boiling points; S4: The vapor of cyhalofop-butyl or its isomers is introduced into the sealing cylinder 1261 through the steam conduit 106, and the high-pressure vapor will drive the steam impeller 1262 to rotate, and then be introduced into the condenser 111 from the outlet end of the sealing cylinder 1261 for condensation to form a liquid, and the liquid of the isomers is discharged through the impurity discharge pipe 114, while the feeding pipe 115 can introduce the liquid of cyhalofop-butyl into the mixing cylinder 121 to mix with zinc sulfate.
