Description

Technical Field

[0001] The invention relates to the field of pesticide herbicides, and in particular to low-temperature crushing equipment for tembotrione raw materials. Background Art

[0002] Tembotrione is a member of the triketone herbicide class and belongs to the HPPD inhibitor class. It was successfully developed by Bayer in 2007. Tembotrione is the youngest member of the triketone herbicide class. Like other HPPD inhibitors, the herbicidal activity of tembotrione is manifested through 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors. After HPPD is inhibited, tyrosine accumulates and plastoquinone is deficient in the weed meristem. After 3-5 days, the weeds show yellowing symptoms, which eventually spread to the whole plant, and the weeds turn white and die. As a new member of the HPPD herbicide class, tembotrione performs equally well in controlling weeds. This herbicide is generally used in combination with the safener isoxadifen to protect corn from ultraviolet damage. It has broad-spectrum, fast-acting characteristics, and is highly compatible with the environment. Compared with the famous mesotrione, tembotrione is not only more active, but also has a wider range of weed control. Cyproconazole also has a strong killing effect on many weeds such as Thistle, Convolvulus, Veronica, Capsicum, Ephedra, Anthemis, and Galium, and can also kill weeds resistant to glyphosate, dicamba, and ALS inhibitor herbicides. In addition, cyproconazole has a strong ability to resist rain erosion and can maintain good herbicidal activity throughout the crop growth period without causing harm to the next crop.

[0003] Cyproconazole is a new generation of highly active herbicides. Compared with other varieties, cyproconazole has the following advantages: it has a strong killing effect on a variety of weeds, no residual activity, strong resistance to rain erosion, and a wide spectrum of weed control. It can effectively control weeds such as Thistle, Convolvulus, Veronica, Capsicum, Ephedra, Anthemis, and Galium. According to statistics, it has a 100% control effect on 18 weeds, 95% on 41, 90% on 56, and 75% on 92. Cyproconazole can maintain good herbicidal activity throughout the growth period of crops, better control broadleaf weeds, and will not cause harm to the next crop.

[0004] Different crystalline forms of commercially important molecules often have different properties that can be used in different situations. Thus, for example, crystalline forms are often more stable than amorphous forms, making them useful for long-term storage of the solid, while amorphous forms are often more soluble than crystalline forms, making them more useful for certain purposes than crystalline forms in terms of drug administration. Small packages for commercial applications require large crystals to be crushed into powder using crushing equipment, but powdered tampoxone is easy to scatter, and existing equipment cannot completely prevent it from scattering, so operators need to wear safety clothing and dust masks, which poses certain safety risks.

[0017] 1. The low-temperature crushing equipment for cyclosulfuron raw materials is provided with a dispersion component and an exhaust component. When the rotor rotates, the fallen cyclosulfuron crystals will be thrown onto the inner wall of the inner shell by the impeller for crushing. Similarly, the high-speed rotating impeller can also crush the cyclosulfuron crystals. When the crystals appear in a powder state, the rotor of the cyclone component rotates, the fan blades blow upward, and the external air enters from the air inlet, and the cyclosulfuron that has become powder is blown out of the exhaust component. At the same time, the cyclosulfuron that has not become powder falls with gravity, is hit by the fan blades again and soars, and then contacts the impeller again to be crushed again. With the completion of crushing, the powdered cyclosulfuron will completely enter the outer shell. The outer shell needs to be connected to an exhaust device, such as a cyclone separator, which can suck the powder while blowing the powder with the cooperation of the cyclone component, thereby achieving the effect of quickly separating the powdered cyclosulfuron and sealing the process to prevent leakage.

[0018] 2. The low-temperature crushing equipment for cyclohexane raw materials is provided with a low-temperature crushing component. Cyclohexane crystals will be crushed by a grinding wheel when they are put in the first step. During the crushing process, the processing area will heat up, especially the metal feed port. Before the temperature rises, the heat near the feed port can be quickly taken in by circulating coolant in the sealing cover, thereby achieving the effect of low-temperature crushing during the initial crushing to prevent volatilization.

[0019] 3. The low-temperature crushing equipment for cyclohexane raw materials is provided with a grinding wheel and a dispersing blade. After the grinding wheel crushes the cyclohexane crystals in the first step, the dispersing blades can hit the cyclohexane crystal fragments to make them collide internally, thereby causing them to be impacted and broken, which is convenient for the next step of crushing and avoids heating due to grinding.

[0035] like Figure 1-10 As shown, a low-temperature crushing equipment for cyclosulfuron raw materials includes a low-temperature crushing component 1, a dispersion component 2 and a bottom shell 3. A cyclone component 6 is installed between the bottom shell 3 and the dispersion component 2. A motor A4 and a motor B5 are fixedly installed inside the bottom shell 3. The motor A4 is used for the operation of the low-temperature crushing component 1, and the motor B5 is used to drive the cyclone component 6 to operate.

[0036] The dispersion assembly 2 includes a rotor 201, an impeller 202, an inner shell 203 and an outer shell 204. The upper end of the inner shell 203 is connected to the low-temperature crushing assembly 1, and the lower end of the inner shell 203 is fixed to the bottom shell 3. The rotor 201 is located in the inner shell 203 and is connected to the inner shell 203 for coaxial rotation. The output shaft of the motor A4 is connected to the rotor 201, and the impeller 202 is fixed to the outside of the rotor 201. The inner wall of the inner shell 203 is provided with a plurality of raised rings 205 arranged up and down. The impeller 202 extends away from one end of the rotor 201. At the raised ring 205, the inner wall of the inner shell 203 is provided with a plurality of vertical grooves 206 distributed in a circular array, and the vertical grooves 206 pass through the raised ring 205. Exhaust components 207 are installed at positions corresponding to the vertical grooves 206 on the inner shell 203. The exhaust components 207 connect the inside and outside of the inner shell 203. The outer shell 204 covers the outside of the inner shell 203, and its upper and lower ends are sealed with the side walls of the inner shell 203. The exhaust component 207 is in the outer shell 204, and two suction pipes 208 are installed on the outer wall of the outer shell 204.

[0037] The outer shell 204 is composed of two semicircular shells, which can be disassembled for cleaning later. The blades of the impeller 202 extend to fit the raised ring 205, but there is a gap between the two. The gap of the exhaust component 207 is smaller. When the cyclosulfuron crystals are not broken into the required particle diameter, they cannot pass through the exhaust component 207. The suction pipe 208 outside the outer shell 204 needs to be connected to a vacuum pump or a cyclone separator with a vacuum pump when actually used.

[0038] Placement grooves 209 are provided at the outer walls of the inner shell 203 corresponding to the vertical grooves 206. The placement grooves 209 connect the inside and outside of the inner shell 203. The exhaust component 207 is fixed in the placement grooves 209. The exhaust component 207 includes a retractable plate 2071. The two retractable plates 2071 are located inside the inner shell 203 at one end close to each other and at the other end far away from each other; it also includes two connecting plates 2072, which are respectively fixedly connected to the upper and lower ends of the two retractable plates 2071. The two connecting plates 2072 are fixed to the upper and lower inner walls of the placement groove 209.

[0039] The diffuse exhaust component 207 can prevent the cyclohexane powder that has passed through from returning easily, and the cyclohexane that has not been crushed into powder can hardly pass through the exhaust component 207.

[0040] The impeller 202 has a plurality of blades 2021 on its exterior, and a U-shaped groove 2022 is formed at one end of the blade 2021 away from the impeller 202 .

[0041] The impeller 202 with the U-shaped groove 2022 can increase the contact force with the tembotrione crystals, and the crushing efficiency is high when striking the tembotrione.

[0042] The lower end of the inner shell 203 is fixedly mounted with a shrinkage cover 7 concentric therewith, the bottom shell 3 is fixed to the lower end of the shrinkage cover 7, the output end of the motor A4 is fixedly mounted with a diffusion cover 8 concentric therewith, the upper end of the diffusion cover 8 is fixed to the rotor 201, the lower end of the diffusion cover 8 and the lower end of the shrinkage cover 7 are in the same plane, the cyclone assembly 6 is between the lower ends of the two, the cyclone assembly 6 is rotatably connected to the shrinkage cover 7 and the diffusion cover 8, and a circle of air inlet holes 9 is provided on the side of the bottom end of the shrinkage cover 7.

[0043] The shrinking cover 7 and the diffusion cover 8 will cause the cyclosulfuron that falls with gravity to hit the cyclone assembly 6, and then be brought upward again by the cyclone assembly 6.

[0044] The cyclone assembly 6 includes a rotating ring 601, which is stuck between the contraction cover 7 and the diffusion cover 8 and is rotationally connected to the two. The output shaft of the motor B5 is installed with a gear 602. The bottom surface of the rotating ring 601 is fixedly installed with a ring gear 603. The gear 602 is meshed with the ring gear 603. The upper surface of the rotating ring 601 is fixedly installed with fan blades 604. When the rotating ring 601 rotates, the fan blades 604 can suck air from the air inlet 9 and blow air upwards.

[0045] The high-speed rotation of the rotating ring 601 will not cause powder to enter between the rotating ring 601 and the shrinking cover 7 or the diffusion cover 8.

[0046] A support ring 605 is fixedly mounted on the bottom end of the shrink cover 7, and the outer circle of the gear ring 603 is clamped in the support ring 605 and is rotatably connected thereto.

[0047] The cryogenic pulverizing assembly 1 comprises a feed port 101 and a grinding wheel 102. The feed port 101 is fixed to the upper end of the inner shell 203 and communicated with the inner shell 203. The grinding wheel 102 is located in the feed port 101 and fixed to the rotor 201. The two are coaxially arranged. The interior of the feed port 101 is a two-stage structure. The diameter of the inner wall of the upper end gradually shrinks downward, and the diameter of the inner wall of the lower end gradually increases downward. The two are combined in the middle position. The grinding wheel 102 is located inside the lower end of the feed port 101. The diameter of the grinding wheel 102 gradually increases from top to bottom. The gap between the grinding wheel 102 and the feed port 101 gradually decreases from top to bottom, the outer wall of the grinding wheel 102 is fixedly mounted with a plurality of convex strips 103 distributed in a circular array, the inner wall of the lower end of the feed port 101 is provided with a circle of concave strips 104 distributed in a circular array, the external fixed cover of the feed port 101 is provided with a sealing cover 105, a coolant circulation pipe 106 is installed on the sealing cover 105, and a plurality of cooling fins 107 are fixedly installed on the external side of one end of the feed port 101 inside the sealing cover 105.

[0048] The structure of the grinding wheel 102 and the feed port 101 can initially crush large pieces of cyclohexane crystals, and the externally arranged sealing cover 105 needs to be connected to a coolant circulation device in the prior art, so as to promptly remove the heat near the feed port 101 during processing.

[0049] A circle of dispersion blades 108 is fixedly installed on the bottom surface of the grinding wheel 102 below the feed inlet 101 .

[0050] A permeable net 210 is fixedly mounted on the upper end of the inner shell 203 below the dispersion blades 108 , and the main shaft of the rotor 201 passes through the permeable net 210 and is rotatably connected thereto.

[0051] When in use, the cyclohexane crystals will be crushed by the grinding wheel 102 when they are put in the first step. During the crushing process, the processing area will heat up, especially the metal feed port. Before the temperature rises, the heat near the feed port 101 can be quickly brought in by circulating the coolant in the sealing cover 105. After the grinding wheel 102 crushes the cyclohexane crystals in the first step, the dispersion blades 108 can hit the cyclohexane crystal fragments, causing them to collide internally, thereby causing them to impact and break, which is convenient for the next step of crushing and avoids heating due to grinding. When the rotor 201 is rotating, the fallen cyclohexane crystals will be thrown by the impeller 202 onto the inner wall of the inner shell 203 for crushing. The same high-speed rotating impeller 202 can also crush the cyclosulfuron crystals. When the crystals appear in powder state, the rotor 201 of the cyclone assembly 6 rotates, and the fan blades 604 blow air upwards. External air enters from the air inlet 9, and the cyclosulfuron that has been turned into powder is blown out from the exhaust assembly 207. At the same time, the cyclosulfuron that has not been turned into powder falls with gravity, is hit by the fan blades 604 again and flies up, and then contacts the impeller 202 again to be crushed again. After the crushing is completed, the powdered cyclosulfuron will completely enter the shell 204. The shell 204 needs to be connected to an exhaust device, such as a cyclone separator, which can suck the powder while blowing it with the cooperation of the cyclone assembly 6.
