[0036] Principle and specific operation process

[0037] The utility model discloses a through existing controller receives sensor signal and controls each part, and the stirrer 102 installed in the stirring barrel 1 rotates at high speed under the drive of motor 103, makes the cleaning water that injects from the water inlet pipe 2 and pyrazole compound solid particle fully mix.Under the double action of water flow impact and stirring shearing force, the impurity attached to the solid surface can be separated, and the particle agglomeration is avoided, and the slurry washing uniformity is guaranteed.

[0038] The filter barrel 5 and the stirring barrel 1 adopt gap fit, and the inner diameter of the filter barrel 5 is equal to the outer diameter of the stirring barrel 1, and the two are closely attached and also convenient to separate.The filter screen 51 in the filter barrel 5 is customized according to the particle size of pyrazole compound particles and the required filtering precision, when the water with impurities after stirring is discharged through the filter barrel 5, the solid particles are intercepted in the filter screen 51, realizing solid-liquid separation, and in actual production, the drain pipe 52 can be connected to the suction filtration device, improving the filtering efficiency.

[0039] The air inlet pipe 3 of the drying device is connected with an air pump, air is introduced when the air pump works, and the electric heating wire 31 around the outer wall of the air inlet pipe 3 is electrified to generate heat, and the heat is transferred to the flowing air through heat conduction, so that the air is heated to become hot air entering the stirring barrel 1.The heat insulating sleeve 32 reduces heat loss and ensures heat efficiency.The stirrer 102 rotates at low speed at this time, so that the hot air is uniformly distributed in the barrel and fully contacts with the damp pyrazole compound, and the moisture is evaporated into water vapor and discharged through the air outlet pipe 4.The temperature sensor 41 on the air outlet pipe 4 monitors in real time, and when the temperature approaches or exceeds the heat-sensitive threshold of pyrazole compound, the feedback signal controls the power of the electric heating wire 31 or the flow of the air pump to prevent the raw materials from deteriorating due to overheating; the humidity sensor 42 detects the water vapor content, and when the humidity decreases to the predetermined drying standard, the drying program is automatically turned off.

[0040] The gasket 55 inside the filtering barrel 5 close to the filter screen 51 is made of elastic material, and when the stirring barrel 1 and the filtering barrel 5 are assembled, the gasket 55 is deformed by extrusion to fill the gap between the two, thereby forming a sealing barrier to prevent liquid leakage. The locking clamp 6 at the joint of the stirring barrel 1 and the filtering barrel 5 tightly fixes the two by mechanical clamping force, resists vibration and pressure impact during stirring and filtering, and maintains the overall stability of the device. The lifting support 53 of the lifting mechanism realizes quantitative height adjustment based on the principle of hydraulic pressure, pneumatic pressure or screw drive, and when discharging, transferring or cleaning is required, the height of the filtering barrel 5 is lowered, and the universal wheel 54 at the bottom of the filtering barrel 5 facilitates the convenient movement of the entire filtering barrel 5.

[0041] In use, first, the pyrazole compound solid raw material to be washed is placed on the filter screen 51 of the filtering barrel 5, then the stirring barrel 1 and the filtering barrel 5 are assembled, the locking clamp 6 is closed to complete the fixation, and at this time, the drain pipe 52 is closed. Then, the valve of the water inlet pipe 2 is opened, an appropriate amount of washing water is injected into the stirring barrel 1, the water amount is pre-set according to the amount of raw material and the washing requirement, the motor 103 is started, and the stirrer 102 is rotated at high speed to ensure that the solid and water are fully mixed and impurities are effectively separated. After the washing is completed, the motor 103 is stopped, the drain pipe 52 is opened, and the water mixed with impurities is discharged from the filtering barrel 5 through the filter screen 51, and the washed raw material is intercepted on the filter screen 51. After the filtering is completed, the drain pipe 52 is closed, the air inlet pipe 3 is connected with the air pump, the air pump is started, and the power of the electric heating wire 31 is turned on. The electric heating wire 31 starts to heat the entering air, and the stirrer 102 starts to rotate at low speed to make the hot air uniformly distributed. The temperature sensor 41 monitors the temperature in the stirring barrel 1 in real time, and when the temperature approaches the maximum allowable drying temperature of the pyrazole compound, the power of the electric heating wire 31 or the flow of the air pump is automatically adjusted through the control system to maintain the temperature stable. The humidity sensor 42 continuously detects the humidity, and when the humidity decreases to the predetermined drying standard, a signal is sent to stop the electric heating wire 31 and the air pump, and the drying operation is stopped. After the drying is completed, the locking clamp 6 is loosened, the lifting mechanism is operated to lower the filtering barrel 5, the filtering barrel 5 is pushed to the specified position through the universal wheel 54, and the dried pyrazole compound finished product is collected. After the discharging is completed, the filtering barrel 5, the stirring barrel 1 and the filter screen 51 are cleaned.

[0042] Although the specific embodiments of the present application are described above with reference to the drawings, it is not a limitation on the protection scope of the present application.
