Description

Technical Field

[0001] The invention relates to the technical field of carbendazim, and in particular to a high-time wetting-type carbendazim wettable powder preparation device. Background Art

[0002] Carbendazim, also known as cotton wilt and benzimidazole 44, is a broad-spectrum fungicide that is effective against fungal diseases in a variety of crops. It can be used for foliar spraying, seed treatment, and soil treatment. It is particularly effective in controlling powdery mildew and blight in melons, early blight in tomatoes, anthracnose and blight in beans, sclerotinia rot in rapeseed, gray mold in onions and leeks, sclerotinia rot in eggplant and cucumbers, anthracnose in melons and beans, powdery mildew in peas, and fusarium wilt in tomatoes.

[0003] Since carbendazim is almost insoluble in water, has stable chemical properties and poor solubility, it is generally prepared into a wettable powder. At present, the carbendazim raw material is usually mixed with a variety of auxiliary materials to prepare carbendazim wettable powder. In order to achieve a long-term wetting of carbendazim wettable powder, the following measures are usually taken: 1. Adding a wetting agent: The wetting agent can increase the surface tension of the wettable powder, making it easier to wet. Organic or inorganic wetting agents can be selected and optimized according to different wetting agent addition amounts and wetting times. 2. Improving the mechanical preparation method: When preparing carbendazim wettable powder, a ball mill is usually used to change the size of the wettable powder particles, thereby improving its wettability;

[0004] Since the volumes of the carbendazim solid raw materials are different, putting all of the carbendazim solid raw materials into the ball mill for ball milling not only wastes the internal space of the ball mill, but also prolongs the ball milling time and reduces production efficiency.

[0005] In summary, there is currently a need for a device and method for preparing a high-efficiency, long-term, wettable carbendazim wettable powder. Summary of the Invention

[0021] The working method of the high-time wetting type carbendazim wettable powder preparation device comprises the following steps:

[0022] S1. Adding carbendazim raw material: feeding the carbendazim solid raw material into the screening cavity through the feed hopper, and the carbendazim fixed raw material falls onto the surface of the dividing plate through the feed hopper;

[0023] S2. Screening carbendazim solid raw material: The piston rod of the first electric cylinder moves upward, driving the U-shaped frame to move upward, and the U-shaped frame drives the first support frame and the second support frame to move upward. The first support frame and the second support frame press against the bottom surface of the protrusion and drive the material dividing plate to move upward to the top through the protrusion;

[0024] At the same time, the two micro electric cylinders are started, and the piston rods of the micro electric cylinders drive the push plates to move inward, and the push plates push the first support frame and the second support frame to move oppositely until the protrusions fall vertically from between the first support frame and the second support frame, and the falling speed of the large volume of carbendazim solid raw material is greater than the falling speed of the small volume of carbendazim fixed raw material. At this time, the piston rod of the third electric cylinder retracts to drive the receiving plate to slide obliquely upward, and the receiving plate separates the large volume of carbendazim fixed raw material from the small volume of carbendazim fixed raw material, and the large volume of carbendazim fixed raw material falls onto the dividing plate, and the small volume of carbendazim fixed raw material falls onto the receiving plate;

[0025] S3. Ball milling large particles of carbendazim solid raw materials and mixing all carbendazim fixed raw materials: the piston rod of the second electric cylinder extends to drive the dividing plate to tilt, and the large volume of carbendazim fixed raw materials on the dividing plate slides into the material transfer channel. The second fan blows the large volume of carbendazim fixed raw materials into the outer cylinder and then turns off the second fan. The ball mill grinds the large volume of carbendazim solid raw materials into small volume of carbendazim fixed raw materials. The second fan blows the small volume of carbendazim fixed raw materials in the outer cylinder into the connecting pipe. The small volume of carbendazim fixed raw materials sieved in step S2 slides down onto the inclined plate through the inclined receiving plate. The piston rod of the third electric cylinder extends to drive the receiving plate to slide downward and push the small volume of carbendazim fixed raw materials on the inclined plate into the side notch and into the feeding pipe, and then into the connecting pipe through the feeding pipe. The second fan blows all the small volume of carbendazim fixed raw materials in the connecting pipe into the mixing cylinder.

[0026] S4. Add dispersant, wetting agent and filler into the mixing drum for mixing: the dispersant, wetting agent and filler are respectively introduced into the corresponding storage box through the feeding pipe, and then introduced into the mixing drum from the corresponding dispersion pipe for mixing. The second motor drives the first stirring shaft and the second stirring shaft to rotate so as to fully mix the carbendazim fixed raw material, the dispersant, the wetting agent and the filler;

[0027] S5. Drying treatment: The mixed solution obtained in S4 enters the drying box under the action of a water pump. The first fan heats the gas outside the box through a heater and then enters the drying box. The high-temperature gas continuously dries the mixed solution. The gas is discharged to the outside of the drying box through an outlet pipe. Finally, the mixed solution obtained becomes carbendazim wettable powder after being fully dried.

[0028] The present invention provides a device for preparing a high-wetting-time carbendazim wettable powder. Compared with the prior art, it has the following beneficial effects:

[0029] A screening mechanism is provided, which includes a dividing plate, a driving straight-falling component, and a receiving plate. The driving straight-falling component drives the dividing plate to rise to the top and then causes the dividing plate to fall vertically. During the vertical falling of the dividing plate, different sizes of carbendazim raw materials fall at different speeds. The large volume of carbendazim fixed raw materials and the small volume of carbendazim fixed raw materials are separated by driving the receiving plate. The large volume of carbendazim fixed raw materials falls onto the dividing plate, and the small volume of carbendazim fixed raw materials falls onto the receiving plate, thereby realizing the screening of the carbendazim raw materials and ball milling the large volume of carbendazim fixed raw materials to avoid the small volume of carbendazim fixed raw materials occupying the volume of the ball mill and improving production efficiency.

DETAILED DESCRIPTION

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] In order to solve the technical problems in the background technology, the following high-time wetting type carbendazim wettable powder preparation device is provided:

[0045] Combine Figures 1-9As shown, the present invention includes a box body 1, a partition 11 and a support plate 12 are fixedly provided inside the box body 1, the support plate 12 is vertically fixed to the partition 11, a screening chamber 13 is provided between the partition 11, the support plate 12 and the box body 1, a feed hopper 8 is fixedly provided on the side wall of the box body 1, the inner end of the feed hopper 8 extends into the screening chamber 13, a ball mill 3, a mixing mechanism 4 and a high-temperature drying mechanism 5 are sequentially arranged in the box body 1, the partition 11 and the support plate 12 separate the screening chamber 13 in the box body 1, which facilitates the screening mechanism 2 to screen the carbendazim raw material and prevents the unscreened carbendazim raw material from escaping from the screening chamber 13.

[0046] The screen mechanism 2 is located in the screen cavity 13, and the screen mechanism 2 includes a material distribution plate 21, a material receiving plate 25, and an inclined plate 27. The middle of the two side walls of the material distribution plate 21 is fixed with a protrusion 212. The lower part of the material distribution plate 21 is provided with a driving straight-down component 22, and the driving straight-down component 22 includes a U-shaped frame 221. The lower part of the support plate 12 is fixed with a first electric cylinder 23. The piston rod of the first electric cylinder 23 slides through the support plate 12 and is fixed with the bottom end of the U-shaped frame 221. The U-shaped frame 221 is fixedly connected, and both sides of the top end thereof are fixed with a limit box 223. The limit box 223 is provided with a first support frame 226 and a second support frame 227 for sliding inside. When the first support frame 226 and the second support frame 227 are pressed against each other, the first support frame 226 and the second support frame 227 are used to support the protrusion 212. When the first support frame 226 and the second support frame 227 are separated, the protrusion 212 falls from between the first support frame 226 and the second support frame 227.

[0047] A plate-passing channel 111, a material-passing through groove, and a straight groove 112 are provided in the middle of the partition 11. The material receiving plate 25 slides in the plate-passing channel 111. Second sliders 251 are fixed on both side walls of the material receiving plate 25. An inclined slide 17 is symmetrically provided on the inner side wall of the box body 1. The second slider 251 slides in the inclined slide 17. The inclined plate 27 and the material receiving plate 25 are both inclinedly arranged above the material dividing plate 21. The side wall of the inclined plate 27 is fixedly connected to the inner side wall of the box body 1. The material receiving plate 25 slides on the inclined plate 27. A first electric cylinder 23 for driving the inclined movement of the material receiving plate 25 is installed on the outside of the box body 1;

[0048] In the above technical solution, the first support frame 226 and the second support frame 227 can be pressed against or separated from each other, thereby ensuring that the dividing plate 21 can be driven to move upward smoothly or the dividing plate 21 can be made to fall due to gravity. Since the falling speed of the large volume of carbendazim solid raw material is greater than the falling speed of the small volume of carbendazim fixed raw material, during the falling process of the carbendazim solid raw material, the carbendazim fixed raw material can be screened by driving the receiving plate 25.

[0049] The first slider 213 is located at one end of the dividing plate 21 close to the partition 11, and the first slider 213 and the corresponding protrusion 212 are located on the same side wall of the dividing plate 21. The first slider 213 is located at one end of the dividing plate 21 close to the partition 11, and the first slider 213 slides in the first straight slide 14 so that the first slider 213 can rotate in the first straight slide 14, and the discharge plate 211 slides in the straight groove 112, and the feeding channel 113 is located at the bottom end of the straight groove 112. A second electric cylinder 24 is fixed on the support plate 12, and the second electric cylinder 24 is located at the end of the dividing plate 21 away from the partition 11. The piston rod of the second electric cylinder 24 extends to push the dividing plate 21 to rotate with the first slider 213 as the base point, thereby tilting the dividing plate 21, and the carbendazim raw material on the dividing plate 21 enters the feeding channel 113.

[0050] A first straight groove 14, a receiving groove 15, and a second straight groove 16 are symmetrically provided on the inner wall of the box body 1. The receiving groove 15 is located on the outside of the second straight groove 16. The two ends of the driving straight-down component 22 slide in the two receiving grooves 15 respectively, and the protrusion 212 slides in the second straight groove 16. The width of the second straight groove 16 can accommodate the separated first support frame 226 and the second support frame 227. The width of the second straight groove 16 is greater than the width of the protrusion 212, ensuring that when the dividing plate 21 rotates with the first slider 213 as the base point, the protrusion 212 will not limit the rotation of the dividing plate 21.

[0051] A mounting frame 222 is provided on the outside of the limit box 223, and the mounting frame 222 is fixed on the outer wall of the connecting frame. Springs 228 are fixed between the first support frame 226, the second support frame 227 and the inner wall of the limit box 223. In the original state, the elastic force of the spring 228 makes the first support frame 226 and the second support frame 227 press tightly against each other. A push plate 225 is provided between the first support frame 226 and the second support frame 227. The inner side edge of the push plate 225 is V-shaped, and the inner side wall of the push plate 225 is in contact with the first support frame 226 and the second support frame 227.

[0057] Example 3

[0058] like Figure 10 As shown, based on the above embodiment, in order to facilitate the preparation of the high-time wetting type carbendazim wettable powder, this embodiment further provides the following working method:

[0059] The method comprises the following steps:

[0060] S1. Adding carbendazim raw material: feeding the carbendazim solid raw material into the screening cavity through the feed hopper, and the carbendazim fixed raw material falls onto the surface of the dividing plate through the feed hopper;

[0061] S2. Screening carbendazim solid raw material: The piston rod of the first electric cylinder moves upward, driving the U-shaped frame to move upward, and the U-shaped frame drives the first support frame and the second support frame to move upward. The first support frame and the second support frame press against the bottom surface of the protrusion and drive the material dividing plate to move upward to the top through the protrusion;

[0062] At the same time, the two micro electric cylinders are started, and the piston rods of the micro electric cylinders drive the push plates to move inward, and the push plates push the first support frame and the second support frame to move oppositely until the protrusions fall vertically from between the first support frame and the second support frame, and the falling speed of the large volume of carbendazim solid raw material is greater than the falling speed of the small volume of carbendazim fixed raw material. At this time, the piston rod of the third electric cylinder retracts to drive the receiving plate to slide obliquely upward, and the receiving plate separates the large volume of carbendazim fixed raw material from the small volume of carbendazim fixed raw material, and the large volume of carbendazim fixed raw material falls onto the dividing plate, and the small volume of carbendazim fixed raw material falls onto the receiving plate;

[0063] S3. Ball milling large particles of carbendazim solid raw materials and mixing all carbendazim fixed raw materials: the piston rod of the second electric cylinder extends to drive the dividing plate to tilt, and the large volume of carbendazim fixed raw materials on the dividing plate slides into the material transfer channel. The second fan blows the large volume of carbendazim fixed raw materials into the outer cylinder and then turns off the second fan. The ball mill grinds the large volume of carbendazim solid raw materials into small volume of carbendazim fixed raw materials. The second fan blows the small volume of carbendazim fixed raw materials in the outer cylinder into the connecting pipe. The small volume of carbendazim fixed raw materials sieved in step S2 slides down onto the inclined plate through the inclined receiving plate. The piston rod of the third electric cylinder extends to drive the receiving plate to slide downward and push the small volume of carbendazim fixed raw materials on the inclined plate into the side notch and into the feeding pipe, and then into the connecting pipe through the feeding pipe. The second fan blows all the small volume of carbendazim fixed raw materials in the connecting pipe into the mixing cylinder.

[0064] S4. Add dispersant, wetting agent and filler into the mixing drum for mixing: the dispersant, wetting agent and filler are respectively introduced into the corresponding storage box through the feeding pipe, and then introduced into the mixing drum from the corresponding dispersion pipe for mixing. The second motor drives the first stirring shaft and the second stirring shaft to rotate so as to fully mix the carbendazim fixed raw material, the dispersant, the wetting agent and the filler;

[0065] S5. Drying treatment: The mixed solution obtained in S4 enters the drying box under the action of a water pump. The first fan heats the gas outside the box through a heater and then enters the drying box. The high-temperature gas continuously dries the mixed solution. The gas is discharged to the outside of the drying box through an outlet pipe. Finally, the mixed solution obtained becomes carbendazim wettable powder after being fully dried.

[0066] The working principle and use process of the present invention:

[0067] When screening:

[0068] The solid raw material of carbendazim is fed into the screening chamber 13 through the feed hopper 8, and the fixed raw material of carbendazim falls onto the surface of the dividing plate 21 through the feed hopper 8. The first electric cylinder 23 is turned on, and the piston rod of the first electric cylinder 23 moves upward to drive the U-shaped frame 221 to move upward. The U-shaped frame 221 drives the first supporting frame 226 and the second supporting frame 227 to move upward. The first supporting frame 226 and the second supporting frame 227 are pressed against the bottom surface of the protrusion 212 and drive the dividing plate 21 to move upward to the second receiving groove 15 at the top through the protrusion 212.

[0069] At the same time, the two micro-electric cylinders 224 are started, and the piston rod of the micro-electric cylinder 224 drives the push plate 225 to move inward, and the push plate 225 pushes the first support frame 226 and the second support frame 227 to move back to each other until the protrusion 212 falls vertically between the first support frame 226 and the second support frame 227, and the first support frame 226 and the second support frame 227 compress the springs 228 at the corresponding positions respectively. The falling speed of the large volume of carbendazim solid raw material is greater than the falling speed of the small volume of carbendazim fixed raw material. At this time, the third electric cylinder 26 is started, and the piston rod of the third electric cylinder 26 is retracted to drive the receiving plate 25 to slide obliquely upward, and the receiving plate 25 separates the large volume of carbendazim fixed raw material from the small volume of carbendazim fixed raw material, and the large volume of carbendazim fixed raw material falls onto the dividing plate 21, and the small volume of carbendazim fixed raw material falls onto the receiving plate 25;

[0070] The second electric cylinder 24 is started. The piston rod of the second electric cylinder 24 is extended and presses against the dividing plate 21, so that the end of the dividing plate 21 close to the feed hopper 8 moves upward. The dividing plate 21 rotates with the first slider 213 as the base point. The dividing plate 21 tilts, and the large volume of carbendazim fixed raw material on the dividing plate 21 slides into the feeding channel 113. The piston rod of the second electric cylinder 24 is retracted to reset the dividing plate 21, and the second fan 7 is started. The second fan 7 blows the large volume of carbendazim fixed raw material into the outer cylinder 31 and then turns off the second fan 7. The ball mill 3 is started to grind the large volume of carbendazim solid raw material into small volume of carbendazim. The carbendazim fixed raw material is removed and the second fan 7 is started again. The second fan 7 blows the small volume of carbendazim fixed raw material in the outer cylinder 31 into the connecting pipe 38. The screened small volume of carbendazim fixed raw material slides down onto the inclined plate 27 through the inclined receiving plate 25. The piston rod of the third electric cylinder 26 extends to drive the receiving plate 25 to slide downward, pushing the small volume of carbendazim fixed raw material on the inclined plate 27 into the side notch 391 and into the feeding pipe 39. Then, the small volume of carbendazim fixed raw material enters the connecting pipe 38 through the feeding pipe 39. The second fan 7 blows all the small volume of carbendazim fixed raw material in the connecting pipe 38 into the mixing cylinder 41.

[0071] When the material dividing plate 21 falls to the bottom, the bottom surface of the material dividing plate 21 contacts the top of the piston rod of the second electric cylinder 24, and the first electric cylinder 23 retracts to drive the first support frame 226 and the second support frame 227 to fall to the bottom. The first support frame 226 and the second support frame 227 are located below the protrusion 212, and the piston rod of the micro electric cylinder 224 retracts. The push rod no longer presses against the first support frame 226 and the second support frame 227. The elastic force of the spring 228 makes the first support frame 226 and the second support frame 227 press against each other again, thereby resetting the driving straight-down assembly 22 to facilitate the next screening.

[0072] When mixing:

[0073] The dispersant, wetting agent, and filler are respectively fed into the corresponding storage box 471 through the feed pipe 472 and then fed into the mixing drum 41 from the corresponding dispersion pipe 473 for mixing. The second motor 46 is started, and the second motor 46 drives the first stirring shaft 42 and the second stirring shaft 43 to rotate in opposite directions to fully mix the carbendazim fixed raw material, the dispersant, wetting agent, and filler.

[0074] When dry:

[0075] Start the water pump 6, the first fan 53, and the heater 52. The obtained mixed solution enters the drying box 51 under the action of the water pump 6. The first fan 53 heats the gas outside the box 1 through the heater 52 and then enters the drying box 51. The high-temperature gas continuously dries the mixed solution. The gas is discharged to the outside of the drying box 51 through the outlet pipe 54. Finally, the obtained mixed solution becomes carbendazim wettable powder after being fully dried.
