Abstract

This utility model discloses a shear emulsification device for pesticide emulsifiable concentrates. The device includes a mixing tank, a coaxial stirring rod, and a lateral stirring rod. The coaxial stirring rod is rotatably and coaxially disposed within the mixing tank, and the lateral stirring rod is rotatably and obliquely disposed within the mixing tank. This application overcomes the shortcomings of existing shear emulsification mechanisms, which often use a coaxial stirring rod, resulting in low mixing efficiency, high agglomeration, difficulty in dispersion, large loss of active ingredient, and low dispersion efficiency and poor dispersion effect for thickeners such as xanthan gum. Therefore, this invention provides a shear emulsification device for pesticide emulsifiable concentrates that simultaneously incorporates both a coaxial stirring rod and a lateral stirring rod.

Description

Technical Field

[0001] This utility model relates to the field of pesticide production technology, specifically to a shearing emulsification device for pesticide emulsifiable concentrates. Background Technology

[0002] Emulsifiable concentrate is a type of pesticide formulation. It is a liquid made by dissolving a high concentration of active ingredient in a solvent and adding an emulsifier. In the preparation process, powdered raw materials are added and mixed with water. However, the powdered raw materials are difficult to dissolve in water, resulting in a large number of impurities in the final emulsifier. This can affect the subsequent application of the emulsifier and clog the spray pipe.

[0003] Chinese Patent No. CN202421592249.1 discloses a shearing emulsification mechanism for the production of pesticide emulsifiable concentrates. This mechanism, through the design of deflecting blades, allows the deflecting blades to be offset from the bottom blades and rotate relative to the bottom blades to a predetermined angle and then stop when the pressure of the local emulsion on the shearing blades increases. This separates the agglomerated impurities, allowing the separated impurities to enter the rectangular opening through the upper and lower sides of the deflecting blades respectively. This makes the impurities finer, reduces agglomeration, and also avoids excessive pressure on the shearing blades caused by agglomerated impurities.

[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution: Existing shear emulsification mechanisms mostly use coaxial stirring rods, resulting in low mixing efficiency, high agglomeration, difficulty in dispersion, large loss of active ingredient, low dispersion efficiency for thickeners such as xanthan gum, and poor dispersion effect.

[0005] Therefore, providing a shear emulsification device for pesticide emulsifiable concentrates that simultaneously employs a coaxial stirring rod and a lateral stirring rod is a problem that this utility model urgently needs to solve. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this invention is to overcome the shortcomings of existing shear emulsification mechanisms, which often employ coaxial stirring rods, resulting in low mixing efficiency, high agglomeration, difficulty in dispersion, significant loss of active pharmaceutical ingredients, and poor dispersion efficiency and effect for thickeners such as xanthan gum. Therefore, this invention provides a shear emulsification device for pesticide emulsifiable concentrates that simultaneously incorporates both a coaxial stirring rod and a lateral stirring rod.

[0007] To achieve the above objectives, this utility model provides a shear emulsification device for pesticide emulsifiable concentrates. The device includes: a mixing tank, a coaxial stirring rod, and a lateral stirring rod. The coaxial stirring rod is rotatably and coaxially disposed inside the mixing tank, and the lateral stirring rod is rotatably and obliquely disposed inside the mixing tank.

[0008] Preferably, the mixing tank is provided with a drive mechanism for driving the coaxial stirring rod and the lateral stirring rod to rotate synchronously; wherein, the drive mechanism includes: a first rotary motor, a first bevel gear and a second bevel gear, the upper end of the coaxial stirring rod is coaxially provided with the first bevel gear, the upper end of the lateral stirring rod is coaxially provided with the second bevel gear meshing with the first bevel gear, the first rotary motor is provided on the mixing tank and is capable of driving the coaxial stirring rod or the lateral stirring rod to rotate.

[0009] Preferably, the lower end of the coaxial stirring rod is provided with a frame-type stirring rack adapted to the interior of the stirring tank.

[0010] Preferably, a fixing frame is inclinedly arranged inside the mixing tank, a stator frame is provided at the lower end of the fixing frame, and a rotor frame is provided at the lower end of the lateral stirring rod.

[0011] Preferably, the rotor frame has a plurality of first shear grooves coaxially arranged around its bottom, and the stator frame has a plurality of second shear grooves coaxially arranged around its periphery.

[0012] Preferably, the lateral stirring rod is coaxially provided with a propeller whose air outlet faces the rotor frame.

[0013] Preferably, a stabilizing frame for supporting the coaxial mixing tank is also provided at the bottom of the mixing tank.

[0014] Preferably, the mixing tank has a feed inlet on one side of the top and a discharge outlet at the bottom.

[0015] Preferably, the feed inlet is provided with a sealing cover, and the discharge outlet is provided with a solenoid valve that can be connected to a pipeline.

[0016] According to the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This application adds raw material powder, water, suspension slurry, thickener, defoamer, antifreeze and other additives to the mixing tank through the feed inlet after opening the sealing cover. Then, the sealing cover is fixed to the feed inlet with bolts. Then, the first rotary motor is started to drive the coaxial stirring rod or the lateral stirring rod to rotate. Thus, through the meshing of the first bevel gear and the second bevel gear, the coaxial stirring rod and the lateral stirring rod are driven to rotate coaxially. The frame-type stirring frame makes the liquid in the mixing tank form a horizontal circulation, so as to prevent the base material from being exposed to the air. After sedimentation, a high-frequency shearing force is generated by the cooperation of the first shearing groove on the rotor frame and the second shearing groove on the stator frame, which directly acts on the emulsifiable concentrate to break it up and improve the fineness of the emulsion. The propeller airflow pushes the material to circulate into the shearing zone to avoid material sticking and improve the shearing emulsification efficiency. After emulsification is completed, the bottom solenoid valve is opened to output the emulsifiable concentrate through the pipeline. The opening degree of the solenoid valve is adjustable to prevent secondary stratification of the emulsion. This device accurately solves the problem of dispersion and homogenization in the production of pesticide emulsifiable concentrates by using coaxial macro-mixing and stirring, lateral shearing emulsification, and propeller airflow to prevent sticking.

[0025] Reference Figure 1 and Figure 2 The mixing tank 1 is equipped with a drive mechanism 4 for synchronously driving the coaxial stirring rod 2 and the lateral stirring rod 3. The drive mechanism 4 includes a first rotary motor 401, a first bevel gear 402, and a second bevel gear 403. The first bevel gear 402 is coaxially mounted on the upper end of the coaxial stirring rod 2, and the second bevel gear 403, meshing with the first bevel gear 402, is coaxially mounted on the upper end of the lateral stirring rod 3. The first rotary motor 401 is mounted on the mixing tank 1 and can drive either the coaxial stirring rod 2 or the lateral stirring rod 3 to rotate. To ensure effective transmission of the first bevel gear 402 and the second bevel gear 403, a protective cover can be provided on their exterior to prevent foreign objects from interfering with their transmission.

[0026] Reference Figure 3 The lower end of the coaxial stirring rod 2 is provided with a frame-type stirring rack 201 that is adapted to the interior of the stirring tank 1.

The cooperation between the first shearing groove 30101 on the sub-frame 301 and the second shearing groove 10201 on the stator frame 102 generates high-frequency shearing force, which directly acts on the emulsifiable concentrate to break it up and improve the fineness of the emulsion.
