The invention discloses a device for preparing a novel pesticide, which comprises a preparation module, a shunting module, a detection module and a signal connection module, and is shown in figures 1 and 2.

As shown in fig. 3, the preparation module includes a drying chamber 101, a first nozzle 102, a second nozzle 103, a first storage tank 104, and a second storage tank 105, wherein two side walls of the drying chamber 101 are symmetrically provided with a first mounting hole and a second mounting hole, the first nozzle 102 is mounted on the first mounting hole, the second nozzle 103 is mounted on the second mounting hole, an inlet end of the first nozzle 102 is connected with one end of a first feeding pipe 106 in a matching manner, the other end of the first feeding pipe 106 is connected with the first storage tank 104 in a matching manner, a first pumping pump 107 is arranged on the first feeding pipe 106, an inlet end of the second nozzle 103 is connected with one end of a second feeding pipe 108 in a matching manner, the other end of the second feeding pipe 108 is connected with the second storage tank 105 in a matching manner, and a second pumping pump 109 is arranged on the second feeding pipe 108; the first storage tank 104 stores a stock solution of pesticide, and the second storage tank 105 stores a powdery carrier.

It should be noted that, the traditional spray granulator generally adopts up-down convection type drying granulation, and the process flow generally is that air is heated by a heater and then blown into the drying tower from the bottom end of the drying tower; the mother liquid (pesticide stock solution) is atomized into fog drops under the action of the atomizer, the fog drops enter the drying tower from the top end of the drying tower, and meet hot air blown into the drying tower in the drying tower to generate violent heat exchange, and the fog drops are dried into required granular powder after a very short time, are accumulated at the bottom of the tower and are discharged by a discharge valve. Although the drying rate is high, the finished product of the produced granules is prepared by directly passing through the drying mother liquor, the inside of the granules is not provided with a supporting carrier, the strength and the hardness are low, the crushing resistance is poor, the pulverization rate is high in the transportation process, the intangible loss is large, the transportation and the storage are not facilitated, and in the drying process inside the drying tower, the dried pesticide granules can be blown by hot air, so that the pesticide granules and the inside of the drying tower collide violently to cause the damage of the finished product of the pesticide granules, the quality of the finished product of the pesticide granules is directly influenced, and the yield of the finished product is low.

In the present invention, granulation is performed by convection drying granulation. Specifically, a stock solution of pesticide (mother liquor) is stored in a first storage tank 104, a powdery carrier is stored in a second storage tank 105, when pesticide particles need to be prepared, a first pumping pump 107 and a second pumping pump 109 are simultaneously started, the stock solution of pesticide stored in the first storage tank 104 is pumped out along a first feeding pipe 106 through the first pumping pump 107, and is conveyed to a first nozzle 102, and the stock solution of pesticide is accelerated, pressurized and atomized in the first nozzle 102 to form a high-speed fluid to be sprayed into a drying chamber 101; similarly, the carriers stored in the second storage tank 105 are pumped out along the second feeding pipe 108 by the second pumping pump 109 and are conveyed to the second nozzle 103, and the carriers form another high-speed fluid after accelerated pressurization in the second nozzle 103 and are simultaneously ejected into the drying chamber 101; at this time, the two high-speed fluids impact each other at the center of the drying cavity 101, and the two high-speed fluids perform amplitude-reducing oscillation movement back and forth, so as to form a highly turbulent impact surface, the impact surface is strongly mixed, and there is high-frequency pressure pulsation, and the axial velocity of the two high-speed fluids on the impact surface tends to zero and changes into radial flow, when the two high-speed fluids impact each other, the powdery carrier can penetrate into the pesticide raw liquid by inertia, and the relative velocity reaches a maximum value at the moment of starting penetration, ideally, the flow velocity can approach twice, so as to combine with the pesticide raw liquid to form mist drops, and when the mist drops carrying the carrier leave the impact surface, the mist drops are dried by the hot gas in the drying cavity 101 to form particles, and then fall onto the diversion bucket 301. Therefore, compared with the traditional up-down convection type drying granulation, the left-right convection type drying granulation is adopted for granulation, the high turbulence of the impact surface and the large phase-to-phase relative speed provide excellent transfer conditions, so that the pesticide stock solution and the carrier can be quickly fused, the prepared pesticide particles are carried with the carrier, the strength and the hardness of the carrier are improved, the crushing resistance is high, and the transportation and the storage are facilitated.

Specifically, when the spraying speed of the pesticide raw liquid at the first nozzle 102 needs to be increased, a certain amount of external air is pumped into the second cavity 408 along the air feeding pipeline 501 through the micro air pump 502, after the certain amount of external air enters the second cavity 408, the second inner side wall 407 expands towards the side far away from the second outer side wall 406, and the second adjusting rod 409 extends to a certain length, so that the volume of a space formed between the second inner side wall 407 is reduced, at this time, when the pesticide raw liquid passes through the adjusting and controlling pipeline 405, the pesticide raw liquid is further compressed, the pressure of the pesticide raw liquid passing through the adjusting and controlling pipeline 405 is increased, and the spraying speed of the pesticide raw liquid at the first nozzle 102 is increased; on the contrary, when needs reduce the speed of pesticide stoste when first nozzle 102 blowout, take the external environment out through miniature air pump 502 to a certain amount of second cavity 408 inside air, take outside back out when a certain amount of second cavity 408 inside air, can make second inside wall 407 to be close to second outside wall 406 one side shrink, and make the second adjust pole 409 shorten to certain length, thereby increase the space volume that forms between the second inside wall 407, when the pesticide stoste was through regulation and control pipeline 405 this moment, the pesticide stoste just can further expand, and then reduce the pressure when the pesticide stoste passes through regulation and control pipeline 405, thereby reduce the speed of pesticide stoste when first nozzle 102 blowout. Therefore, the function of adjusting the spraying speed of the pesticide stock solution at the first nozzle 102 is realized through the adjusting and controlling pipeline 405, the structure is simple, the control is easy, the manufacturing cost is low, and the automatic spraying device is suitable for large-area automatic production workshops.

An air pressure sensor is arranged in the second cavity 408 and used for detecting the air pressure value inside the second cavity 408, and the air pressure sensor can feed the detected air pressure value back to a control system of the detection module, so that the detection module can adjust the expansion and contraction amount of the second adjusting rod 409 according to the air pressure value inside the second cavity 408.

It should be noted that, in the process of adjusting the speed of the pesticide stock solution sprayed out from the first nozzle 102 through the adjusting and controlling pipe 405, the gas pressure value inside the second cavity 408 is monitored in real time through the gas pressure sensor, and then the shrinkage or expansion of the second inner side wall 407 is converted according to the gas pressure value, so that the function of accurate adjustment and control is realized.

The invention also discloses a control method of the device for preparing the novel pesticide, which is applied to any one of the devices for preparing the novel pesticide and comprises the following steps:

It should be noted that the pre-trained defect image information includes image information of hollow, adhesive, charred, and broken defects. The first defect proportion value is the ratio of the total number of the bonded and hollow defective granular pesticides appearing in the image of the granular pesticide product shot by the industrial camera to the total number of all granular pesticides in the image during primary detection; the second defect proportion value is the ratio of the total number of burnt and broken defective granular pesticides appearing in the image of the granular pesticide product shot by the industrial camera to the total number of all granular pesticides in the image during one-time detection.

In the finished product of the obtained pesticide granules, defects such as adhesion, hollowness, scorching, and breakage may occur. In the process of forming the blank body, heat is transferred to the inside of the fog drop, and moisture diffuses from the surface of the internal phase of the fog drop and evaporates to the air, and in the process, if the moisture evaporation speed of the fog drop (namely the drying speed of the fog drop) is far less than the diffusion speed of water molecules from the external surface, the fog drop is easy to expand and deform, so that the particle pesticide has a defect of a hollow type, and the inside of the particle pesticide in the situation is not completely dried and falls onto the diversion bucket, and then the moisture in the particle pesticide expands towards the external surface of the particle pesticide, so that the external surface of the particle pesticide has higher humidity, and the particle pesticides are bonded with each other, so that the defect of a bonding type occurs, and the fundamental reason of the defects of hollowness and bonding is that the generated fog drops are too large or the drying temperature in the drying cavity is too low, so that the complete drying cannot be performed in time. On the contrary, if the evaporation rate of the water in the mist drops (i.e. the drying rate of the mist drops) is much higher than the diffusion rate of the water molecules from the outer surface, the water on the mist drops is evaporated rapidly, and before the granular pesticide falls out of the drying cavity, the water in the granular pesticide is evaporated excessively, so that the defects of the types of scorching and crushing are caused, and the root cause of the defects of the types of scorching and crushing is caused by that the water in the mist drops is evaporated too fast in the drying cavity because the generated mist drops are too small or the drying temperature in the drying cavity is too high.

Firstly, establishing a defect recognition model in advance through a neural network, and then importing pre-trained defect image information into the defect recognition model for training to obtain a trained defect recognition model; then shooting images of the pesticide product to be detected on one or more conveyor belts by an industrial camera within a preset time; the images are led into a trained defect recognition model for recognition, so that whether a first preset defect and a second preset defect exist in the shot images or not is recognized, the number of the corresponding defects is calculated, and then a first defect proportion value and a second defect proportion value are calculated; then judging whether the first defect proportion value and the second defect proportion value are larger than a preset threshold value or not; and if so, adjusting the processing parameters of the preparation module based on the first defect proportion value and the second defect proportion value.

In the right-left convection drying granulation method, the reason why the mist is too small is that the velocity of spraying the raw pesticide solution from the first nozzle is too high, so that the kinetic energy carried by the raw pesticide solution when the raw pesticide solution collides with the carrier on the collision surface is too high, so that the raw pesticide solution on the collision surface and the carrier keep high flow velocity after the collision direction is changed, and further the contact time of the raw pesticide solution and the carrier is short, and the generated mist is too small.

On the contrary, the reason that the fog drops are too big is that the kinetic energy carried by the pesticide stock solution when the impact surface impacts the carrier is too small due to the fact that the spraying speed of the pesticide stock solution at the first nozzle is too small, so that the pesticide stock solution on the impact surface and the carrier keep a low flow speed after the impact direction is changed, the contact time of the pesticide stock solution and the carrier is long, the generated fog drops are too big, and therefore when the fog drops are too big, the diameter of the fog drops can be reduced by improving the spraying speed of the pesticide stock solution at the first nozzle.

Therefore, in the invention, if the first defect proportion value is larger than the preset threshold value, the first temperature information in the drying cavity is obtained through the temperature sensor, and whether the first temperature information is within the preset range value is judged; if the second adjusting rod is located, the reason that the hollow is caused and the bonding defect is too much is not caused by too low drying temperature but caused by too large fog drops, the first detection result is generated at the moment, the first detection result is fed back to the control system of the preparation module through the signal connection module, the control system of the preparation module controls the micro air pump to be started at the moment, and the external air is pumped into the second cavity through the micro air pump, so that the second adjusting rod extends, the pressure of the pesticide stock solution in the first feeding pipe is increased, the spraying speed of the pesticide stock solution at the first nozzle is increased, the diameter of the fog drops is reduced, and the generation of the hollow and bonding defects is reduced. If not, the reason that the hollow and bonding defects are too much is caused by too low drying temperature, a second detection result is generated at the moment, the second detection result is fed back to the control system of the preparation module through the signal connection module, and the control system of the preparation module increases the heating power of the gas heater, so that the heat exchange capacity of hot gas in the first cavity is improved, the drying temperature in the drying cavity is further improved, and the generation of the hollow and bonding defects is further reduced.

And if the second defect proportion value is larger than a preset threshold value, acquiring second temperature information in the drying cavity through a temperature sensor, and judging whether the second temperature information is within a preset range value. If the second cavity adjusting rod is located, the third detection result is generated at the moment, the third detection result is fed back to the control system of the preparation module through the signal connection module, the control system of the preparation module controls the micro air pump to be started at the moment, air in the second cavity is pumped out of the second cavity through the micro air pump, the second adjusting rod is shortened, the pressure of the pesticide stock solution in the first feeding pipe is reduced, the spraying speed of the pesticide stock solution at the first nozzle is reduced, the diameter of the fog drops is increased, and the generation of scorching and breaking defects is reduced. If not, the reason that the burning and crushing defects are too much caused by too high drying temperature is shown, a fourth detection result is generated at the moment, the fourth detection result is fed back to the control system of the preparation module through the signal connection module, and the control system of the preparation module reduces the heating power of the gas heater, so that the heat exchange capacity of hot gas in the first cavity is reduced, the drying temperature in the drying cavity is reduced, and the burning and crushing defects are reduced.

In conclusion, the invention can identify the defect information of pesticide particles through the detection module to generate a corresponding detection result, and then feed the corresponding detection result back to the preparation module through the signal connection module, so that the preparation module can adjust the processing parameters according to the detection result, the functions of online monitoring and intelligent adjustment are realized, the condition of large-scale defective products is avoided, and the invention is suitable for large-scale unmanned automatic production workshops.

In addition, the control method of the device for preparing the novel dosage form pesticide further comprises the following steps:

acquiring the limit collision momentum values of various types of carriers through a big data network, and establishing a database based on the limit collision momentum values of the various types of carriers; wherein the limit collision momentum value is a critical value that the carrier is damaged due to collision;

acquiring carrier type information of a current preparation process, and importing the carrier type information of the current preparation process into the database to obtain a preset limit collision momentum value of the carrier of the current preparation process;

acquiring pressure values of a first nozzle and a second nozzle of the current preparation process, and calculating an actual collision momentum value when the pesticide stock solution collides with the carrier based on the pressure values of the first nozzle and the second nozzle;

judging whether the actual collision momentum value is larger than a preset limit collision momentum value or not;

if the pressure of the pesticide raw liquid in the first feeding pipe is higher than the pressure of the pesticide raw liquid in the first feeding pipe, the micro air pump pumps air in the second cavity out of the second cavity, so that the second adjusting rod is shortened, the pressure of the pesticide raw liquid in the first feeding pipe is reduced, and the spraying speed of the pesticide raw liquid in the first nozzle is reduced.

It should be noted that, because the structures of different types of carriers are not consistent, and the extreme collision momentum values are also different, first, the extreme collision momentum values of various types of carriers can be obtained through a big data network, and a database is established based on the extreme collision momentum values of the various types of carriers; then, when in actual production, firstly obtaining the carrier type information used in the current preparation process, and then importing the carrier type used in the current preparation process into a database so as to obtain a preset limit collision momentum value; then, working pressure information on the first nozzle and the second nozzle is obtained through a pressure sensor, and an actual collision momentum value when the pesticide stock solution collides with the carrier is calculated; if the actual collision momentum value is larger than the preset limit collision momentum value, the air in the second cavity is pumped out of the second cavity through the miniature air pump, so that the second adjusting rod is shortened, the pressure of the pesticide stock solution in the first feeding pipe is reduced, the spraying speed of the pesticide stock solution at the first nozzle is reduced, the actual collision momentum value when the pesticide stock solution collides with the carrier is reduced, and the phenomenon that the carrier is damaged by collision of the pesticide stock solution and the carrier is avoided.
