Description

Technical Field

[0001] The present invention relates to the field of drying devices, and specifically to a continuous drying device for mesotrione. Background Art

[0002] Mesotrione is an organic compound with the molecular formula C14H13NO7S. It is a benzoylcyclohexanedione herbicide and an effective competitive hydroxyphenylpyruvate dioxygenase inhibitor. During the drying process of mesotrione, the material to be dried will be lost along with the drying medium and discharged as waste gas, which not only pollutes the environment but also causes waste of resources. The drying effect of traditional drying equipment is not good, and the raw materials need to be recycled multiple times.

[0003] For example, Chinese Patent Publication No.: CN218915583U discloses a continuous drying device for mesotrione, which includes a workbench. A positive pressure silo, a drying main machine, a drying tower, a screw feeder, a heat exchanger, a cyclone separator, a dry product silo, a material collecting auger, a bag filter, a condenser, a storage tank, a condensate storage tank, and an induced draft fan are installed on the workbench. The positive pressure silo is located directly above the screw feeder, and one end of the screw feeder is arranged inside the drying main machine. The present invention uses an inert gas as the drying medium to avoid the oxidation problem during the drying process of mesotrione. The dried product is cooled before packaging to avoid the oxidation problem of mesotrione due to high temperature after coming out of the drying system. The inert medium is recycled in the drying system, reducing the drying cost. The drying process uses a crushing and grading device to meet the fineness requirements.

[0004] In this solution, when the heated gas dries mesotrione, there may be a problem of incomplete drying. The hot air cannot evenly pass through mesotrione, and there will still be a problem of particle escape if a cyclone separator and a bag filter are used to separate mesotrione. If the filtering effect is good, there will be a problem of wind blockage. Summary of the Invention

The multiple floating disks are inside the air extraction pipe and slide up and down relative to the air extraction pipe. The floating disks and the conical filter meshes are connected by hanging rods. There are multiple through holes A running through vertically on the floating disks, and a limiting ring for preventing the floating disks from moving upwards excessively is provided on the inner wall of the upper end of the air extraction pipe.

[0012] Preferably, a plurality of strip-shaped protrusions are fixedly provided on the inner wall of the air extraction pipe, and grooves matching the strip-shaped protrusions are formed on the sides of the floating disks. The strip-shaped protrusions are used to limit the floating disks to only slide up and down relative to the air extraction pipe.

[0013] Preferably, the cyclone separation component includes a cyclone separator. The end of the bent pipe away from the filtration tank is connected to and communicates with the upper end of the cyclone separator. An air inlet pipe is installed at the cut corner on the side of the cyclone separator, and the other end of the air inlet pipe is connected to the continuous drying component;

[0014] An aggregate bucket is hermetically fixed at the bottom of the cyclone separator.

[0015] Preferably, a discharge port B with a valve is installed at the bottom end of the aggregate bucket.

[0016] Preferably, the continuous drying component includes a drying barrel. The end of the air inlet pipe away from the cyclone separator is connected to and communicates with the side wall of the drying barrel; a feed port with a valve is installed at the upper end of the drying barrel;

[0017] A bottom shell is fixed at the bottom end of the drying barrel. The inside of the bottom shell is a hollow structure, and there are several air holes B on the side of the bottom shell;

[0018] A hot air pipe is inserted from the upper end of the drying barrel and fixed to the bottom shell. The hot air pipe is connected to the hollow structure inside the bottom shell;

[0019] The motor is fixed at the bottom of the bottom case, and its output shaft penetrates through the central position of the bottom case. Multiple blades are installed on the output shaft of the motor.

[0020] Preferably, the bottom case is of a conical structure, and the conical tip of the bottom case faces downward. The output shaft of the motor penetrates through its conical center.

[0021] Preferably, the heating assembly includes a heating barrel, a long tube, a short tube, and a heating coil. One end of the hot air duct away from the drying barrel is connected to the long tube. Both the long tube and the short tube are inserted into the heating barrel. The bottom end of the long tube is below the bottom end of the short tube inside the heating barrel. Multiple heating coils are provided and are fixedly arranged side by side up and down inside the heating barrel. The heating coils are sleeved on the long tube and the short tube. One end of the short tube away from the heating barrel is connected to the air outlet end of the circulating air blower.

[0022] Preferably, an observation assembly is further included. The observation assembly includes an observation barrel and two conduction tubes. Both conduction tubes are hermetically inserted into the observation barrel. One end of one conduction tube away from the observation barrel is connected to the air extraction pipe, and the other end of the other conduction tube away from the observation barrel is connected to the air inlet end of the circulating air blower.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In this continuous sulfentrazone drying device, by setting a multi-layer filtration assembly, the hot air still contains tiny sulfentrazone methyl materials after cyclone separation. When extracting air, multiple conical filter meshes can achieve the effect of filtering dust. The isolated dust will fall onto the conical disc until it falls below the conical disc through the leakage hole A. Since multiple conical discs are provided and are arranged staggeredly, the fallen dust is difficult to be carried back to the conical filter mesh by the wind force. The air extraction pipe is in a negative pressure air extraction state, so the floating disc inside it will move upward during air extraction. And because the conical filter mesh has a certain weight, and there are air holes A on the floating disc, the floating disc will also fall after moving upward, and can perform an up-and-down transformation action. When performing the up-and-down transformation, the dust blocked on the conical filter mesh will be shaken off. The dust on the lower conical filter mesh can be discharged downward through the central leakage hole B. After being discharged, the dust is isolated by the conical disc and is not easy to return to the conical filter mesh again. Thus, the effect of separating and drying sulfentrazone methyl in the air can be achieved, avoiding waste of raw materials and also preventing the dried air from polluting the environment.

[0025] 2. In this continuous drying device for mesotrione, by setting up a continuous drying component, mesotrione is directly put into the drying barrel. Since hot air is ejected from the bottom housing, mesotrione can be dried in the drying barrel. After drying, the motor drives the blade to crush mesotrione. The crushed particles can be dried again by the hot air blown out from the air holes B on the housing. Therefore, when gradually crushing, from large particles to small dust particles, they are all surrounded by hot air until the crushed particles are small enough to be drawn away by the circulating air and then separated by a cyclone separator, achieving the effect of fully drying mesotrione until the drying requirement is met.

[0026] 3. In this continuous drying device for mesotrione, by setting up a heating component, since the wind force is cyclic, the drying air whose heat is carried away by mesotrione can be heated again by the heating component. After heating, the moisture in the drying gas will evaporate and be discharged. Since the gas is heated every time it dries mesotrione, a better drying effect can be achieved.

[0042] As Figures 1-10 shown, a continuous drying device for mesotrione includes a circulating blower 1, and also includes a cyclone separation component 2, a multi-layer filtering component 3, a heating component 4, and a continuous drying component ⑤. The circulating blower 1 conveys wind power to the heating component 4, the heating component 4 sends hot air into the continuous drying component 5, the continuous drying component 5 sends materials into the cyclone separation component 2, and then leads to the multi-layer filtering component 3 until it is connected to the circulating blower 1 again;

[0043] The multi-layer filtering component 3 includes a filtering tank 301, which is provided with a discharge port A302 with a valve at its bottom end, its side is connected to the air extraction end of the cyclone separation component 2 by a bent pipe 303, and its top end is connected to the air inlet end of the circulating blower 1;

[0044] It also includes an air extraction pipe 304, which is fixed to the upper end of the filtering tank 301, and the two are internally connected;

[0045] Conical disks 305, with their tips facing downwards, and a leakage hole A306 penetrating up and down is provided at the center of the conical disk 305. There are multiple conical disks 305, which are arranged vertically and fixed inside the filtering tank 301, and the leakage holes A306 of the multiple conical disks 305 are arranged staggeredly;

[0046] Conical filter meshes 307, there are multiple of them, arranged vertically and distributed, and the multiple conical filter meshes 307 are fixedly connected to each other. Except for the uppermost conical filter mesh 307, leakage holes B308 are provided at the middle positions of the remaining conical filter meshes 307. The connection between the bent pipe 303 and the filtering tank 301 is between the lowermost conical filter mesh 307 and the uppermost conical disk 305;

[0047] Floating disks 309, there are multiple of them, arranged vertically and fixed together. The multiple floating disks 309 are located inside the air extraction pipe 304 and slide up and down relative to the air extraction pipe 304. The floating disks 309 are connected to the conical filter meshes 307 by hanging rods 310. Multiple air holes A311 penetrating up and down are provided on the floating disks 309. A limiting ring 312 for preventing the floating disks 309 from moving upwards excessively is provided on the inner wall of the upper end of the air extraction pipe 304.

[0048] The circulating blower 1 is a high-pressure vortex air pump, which can realize the circulating flow of the entire gas route and can operate stably in a gas environment containing dust. The discharge port A302 can be manually opened. When opened, it is used for discharging materials and can be opened after the circulating blower 1 stops. The conical filter screen 307 is a conical filter cloth with different mesh sizes on each layer. When the raw material particles pass through the conical filter screen 307, they will get stuck in the mesh. The conical disk 305 can be made of stainless steel and needs to meet a certain smoothness. After drying, the particles on the conical disk 305 can easily roll to the position of the leakage hole B308.

[0049] A plurality of strip-shaped protrusions 313 are fixedly arranged on the inner wall of the air extraction pipe 304. Grooves matching with the strip-shaped protrusions 313 are formed on the side edges of the floating disk 309. The strip-shaped protrusions 313 are used to limit the floating disk 309 to only slide up and down relative to the air extraction pipe 304.

[0050] The groove size of the floating disk 309 is larger than the size of the strip-shaped protrusions 313, so there is a small friction force between the two, making the floating disk 309 float under the action of negative pressure.

[0051] The cyclone separation assembly 2 includes a cyclone separator 201. One end of the elbow 303 far from the filter tank 301 is connected and communicated with the upper end of the cyclone separator 201. An air inlet pipe 202 is installed at the side cut angle of the cyclone separator 201. The other end of the air inlet pipe 202 is connected to the continuous drying assembly 5;

[0052] The aggregate bucket 203 is hermetically fixed at the bottom of the cyclone separator 201.

[0053] A discharge port B204 with a valve is installed at the bottom end of the aggregate bucket 203.

[0054] The raw material particles separated by the cyclone separator 201 will fall into the aggregate bucket 203. The bottom of the aggregate bucket 203 can be opened for discharging after the circulating blower 1 stops.

[0055] The continuous drying assembly 5 includes a drying barrel 501. One end of the air inlet pipe 202 far from the cyclone separator 201 is connected to the side wall of the drying barrel 501 and communicated with its interior; A feed port 502 with a valve is installed at the upper end of the drying barrel 501;

[0056] The bottom shell 503 is fixed at the bottom end of the drying barrel 501. The interior of the bottom shell 503 is a hollow structure, and several air holes B504 are provided on the side of the bottom shell 503;

[0057] The hot air pipe 505 is inserted into the upper end of the drying barrel 501 and fixed to the bottom shell 503. The hot air pipe 505 is communicated with the hollow structure inside the bottom shell 503;

[0058] The motor 506 is fixed to the bottom of the bottom shell 503, and its output shaft passes through the central position of the bottom shell 503. Multiple blades 507 are installed on the output shaft of the motor 506.

[0059] The upper feed port 502 is used to add mesotrione that needs to be dried. After adding, the feed port 502 can be covered with a sealing cover. The bottom shell 503 closes the bottom position of the drying barrel 501. The hot air pipe 505 can heat up the bottom shell 503, and the hot air can be ejected from the air hole B504 of the bottom shell 503 and act on the mesotrione.

[0060] The bottom shell 503 is a conical structure, and the conical tip of the bottom shell 503 faces downward. The output shaft of the motor 506 passes through its conical center.

[0061] The mesotrione will gather towards the central position of the bottom shell 503, and after gathering, it will be broken by the blades 507 driven by the motor 506.

[0062] The heating assembly 4 includes a heating barrel 401, a long pipe 402, a short pipe 403, and a heating coil 404. One end of the hot air pipe 505 away from the drying barrel 501 is connected to the long pipe 402. Both the long pipe 402 and the short pipe 403 are inserted into the heating barrel 401. Inside the heating barrel 401, the bottom end of the long pipe 402 is below the bottom end of the short pipe 403. Multiple heating coils 404 are provided and are fixedly arranged side by side up and down inside the heating barrel 401. The heating coils 404 are sleeved on the long pipe 402 and the short pipe 403. One end of the short pipe 403 away from the heating barrel 401 is connected to the air outlet end of the circulation blower 1.

[0063] The heating coil 404 is a resistive heating pipe installed in the heating barrel 401. The cable passes through the heating barrel 401. The heating coil 404 is powered by external electricity. A heat preservation structure can be arranged inside the heating barrel 401. The arrangement of the short pipe 403 and the long pipe 402 can improve the heat transfer efficiency. A temperature sensor, a thermometer, and an electromagnetic steam valve are also installed on the heating barrel 401 for discharging the water vapor evaporated in the drying gas.

[0064] An observation assembly 6 is further included. The observation assembly 6 includes an observation barrel 601 and two conduction pipes 602. Both conduction pipes 602 are hermetically inserted into the observation barrel 601. One end of one conduction pipe 602 away from the observation barrel 601 is connected to the air extraction pipe 304, and one end of the other conduction pipe 602 away from the observation barrel 601 is connected to the air inlet end of the circulation blower 1.

[0065] A glass observation window is provided on the observation barrel 601, which can be used to observe the precipitated raw materials, thereby judging the filtration situation of the particles in the previous process and the raw material particles entering the circulation blower 1.

[0066] In use, the circulating blower 1 can blow air into the heating component 4. The heating component 4 can raise the temperature of the drying gas. The mesotrione to be dried is put into the drying barrel 501. The bottom shell 503 of the drying barrel will eject hot air. Therefore, the mesotrione can be dried in the drying barrel 501. After drying, the motor 506 drives the blade 507 to crush the mesotrione. The crushed particles can be dried again by the hot air blown out from the air hole B504 on the bottom shell 503. Therefore, when gradually crushing, from large particles to small dust particles, they are all surrounded by hot air until the crushed particles are small enough. Under the action of the circulating blower 1, they can be sucked away by the circulating air;

[0067] The raw material particles sucked away are separated and settled by the cyclone separator 201 in the cyclone separation component 2. The settled raw materials will accumulate in the aggregate bucket 203 and be discharged intermittently. The smaller raw materials will enter the multi-layer filtration component 3;

[0068] The hot air after cyclone separation still contains tiny mesotrione materials. When exhausting air, multiple conical filters 307 can achieve the effect of filtering dust. The isolated dust will fall onto the conical disk 305 until it falls from the leakage hole A306 to the lower part of the conical disk 305. Since there are multiple conical disks 305 and they are arranged staggeredly, the fallen dust is difficult to be carried back to the conical filter 307 by the wind force again. The air extraction pipe 304 is in a negative pressure air extraction state. Therefore, when extracting air, the floating disk 309 inside it will move upward. And because the conical filter 307 has a certain weight and there are air holes A311 on the floating disk 309, the floating disk 309 will fall after moving upward, and can perform the action of moving up and down. When moving up and down, the blocked dust on the conical filter 307 will be shaken off. The dust on the lower conical filter 307 can be discharged downward from the central leakage hole B308. After being discharged, the dust is isolated by the conical disk 305 and is not easy to return to the conical filter 307 again.
