Description

Technical Field

[0001] This invention belongs to the field of pesticide processing technology, specifically an emulsification device for pesticide suspensions. Background Technology

[0002] Pesticide suspensions are a type of suspension preparation made by using water as the dispersion medium and uniformly dispersing emulsifiers in the form of extremely small droplets in the pesticide liquid, followed by mixing and emulsification.

[0003] Typically, pesticide suspensions are emulsified by injecting emulsifiers and liquid pesticides into a reaction vessel, where a high-speed rotating agitator achieves mixing and emulsification. However, because the emulsifier and liquid pesticides are injected rapidly, they are initially in a stratified state within the vessel. The reaction vessel's over-reliance on the high-speed rotating agitator can easily lead to the formation of laminar flow zones and dead zones within the vessel due to the shearing action of the agitator, resulting in uneven mixing. Furthermore, while the strong shear force from the high rotation speed helps with initial dispersion, it can also damage already formed micro-droplets and affect the stability of the emulsion system. Therefore, to address these issues, an emulsification device for pesticide suspensions is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides an emulsification device for pesticide suspensions, which solves the problems that the method of emulsification and stirring using a stirring head alone will lead to uneven local mixing of the suspended pesticide and that the high-speed rotating stirring head will damage the already formed micro-droplets.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an emulsification device for pesticide suspension, comprising a barrel and a feeding pipe and a discharge port respectively installed at its top and bottom, a cover being installed at the top of the barrel, and further comprising: a stirring mechanism disposed on the barrel, a transmission mechanism being installed at the top of the cover cavity and being connected to the stirring mechanism, and a cam being installed on the transmission mechanism that can be driven and rotated by it, and an adjuvant adding mechanism being installed at the top of the barrel;

[0006] The additive addition mechanism includes a storage tank fixed to the top of the cover, with the bottom of the storage tank extending into the cover and connected to a feeding pipe. The bottom end of the feeding pipe is an atomizing nozzle, and the bottom of the feeding pipe is provided with a one-way valve that can conduct downward unidirectionally. The middle part of the feeding pipe is provided with a one-way valve that can conduct unidirectionally into the feeding pipe. A spring piston rod with an outward tendency is movably installed in the cavity at the top of the feeding pipe. One end of the spring piston rod can abut against the outer periphery of a cam, and the cam is provided with a cross-section.

[0007] When the cam rotates, it can compress the spring piston rod to block the connection between the feeding pipe and the storage tank, and push out the emulsifier in the feeding pipe.

[0008] Preferably, the stirring mechanism includes a motor fixedly installed at the bottom of the barrel, the output end of the motor extending into the cavity at the bottom of the barrel and being drivenly connected to a stirring paddle, the stirring paddle being rotatably connected to the barrel.

[0009] Preferably, the transmission mechanism includes a sun gear fixedly sleeved on the top of the stirring paddle rod, a plurality of fixed shafts fixedly connected in a circular array on the top of the cover, planetary gears rotatably connected to the outer periphery of the fixed shafts, an internal gear ring also provided on the top of the cover cavity, and the bottom of the plurality of fixed shafts can support the bottom of the internal gear ring; the sun gear can mesh with the plurality of fixed shafts, and the plurality of fixed shafts can mesh with the internal gear ring, and the cam is fixedly sleeved on the outer periphery of the internal gear ring.

[0010] Preferably, one end of the feeding pipe inside the cover body is a hollow ring and is sleeved on the outer periphery of the stirring paddle shaft body. The bottom of the hollow ring of the feeding pipe is provided with several oblique holes.

[0011] Preferably, an elastic diaphragm located below the transmission mechanism is fixedly installed at the bottom of the cavity of the cover, the feeding tube can pass through the elastic diaphragm, and the middle part of the elastic diaphragm is movably sleeved on the outer periphery of the stirring paddle rod; in the initial state, the elastic diaphragm is inverted funnel shape.

[0012] Preferably, the top of the rod portion of the stirring paddle is equipped with a vibration component located below the transmission mechanism for driving the elastic diaphragm to continuously reciprocate in the vertical direction.

[0013] Preferably, the vibration assembly includes a hollow column movably sleeved on the top of the rod portion of the stirring paddle, a guide groove is provided inside the hollow column, and a plurality of limiting columns are fixedly connected to the top of the hollow column in a circular array. The top of the limiting columns can pass upward through the fixed shaft and extend to the top of the cover, and the limiting columns are movably sleeved in the fixed shaft; the middle part of the elastic diaphragm is fixedly connected to the outer periphery of the hollow column.

[0014] The top of the rod portion of the stirring paddle is fixedly connected to a convex shaft that can slide in the guide groove, and the cover has a constant pressure hole that is higher than the elastic diaphragm in the vertical direction.

[0015] Preferably, the guide groove includes an upper arc groove and a rubber scraper ring formed on the hollow column, and the top and bottom ends of the upper arc groove are respectively connected to the top and bottom ends of the lower arc groove.

[0016] Preferably, a rubber scraper ring is fixedly installed at the bottom of the hollow column, and the rubber scraper ring is movably sleeved outside the rod part of the stirring paddle.

[0017] Preferably, a vertical groove is formed on the rod portion of the agitator; a flow guiding assembly is installed on the rod portion of the agitator; the flow guiding assembly includes a float and a hollow cylinder movably sleeved on the rod portion of the agitator, a plurality of flexible flow guiding plates are arranged in a ring array on the outer periphery of the hollow cylinder, the bottom of the hollow cylinder is fixedly connected to the top of the float, a plurality of counterweights are fixedly connected to the bottom of the float, and a connector is fixedly connected to the cavity of the hollow cylinder, and the connector is movably installed in the vertical groove;

[0018] The edges of two adjacent flexible guide vanes can be positioned directly below the blade portion of the agitator at the joint.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] The above solution involves inputting liquid medicine through a feeding pipe and discharging it through an oblique hole. A motor drives a stirring paddle to agitate the liquid inside the tank. Simultaneously, the stirring paddle, through a transmission mechanism, drives a cam to rotate. This causes the cam to intermittently compress a spring piston rod to first seal the connection between the storage tank and the feeding pipe. Subsequently, the continued movement of the spring piston rod disperses the emulsifier in the feeding pipe through an atomizing nozzle, allowing it to fall evenly onto the liquid surface at the bottom of the tank. This achieves uniform addition of the liquid medicine and emulsifier, and the medicine is mixed evenly in layers during the addition process. At this point, the stirring paddle does not need to operate at excessively high speeds to perform efficient emulsification and mixing.

[0021] The above scheme uses the rotation of the stirring paddle to drive the cam shaft to rotate and slide in the guide groove. At this time, under the limiting action of the hollow column and the fixed shaft, the hollow column reciprocates in the vertical direction. At the same time, the hollow column also drives the middle part of the elastic diaphragm to reciprocate in the vertical direction, thereby avoiding the situation where some of the diffused drug molecules injected into the barrel from the atomizing nozzle and the oblique hole will adhere to the elastic diaphragm.

[0022] The above solution works by having the liquid medicine and emulsifier injected into the tank. During this process, the medicine sprayed from the angled hole impacts the rod of the agitator and falls onto the flexible guide plate for dispersion. The presence of the flexible guide plate prevents the liquid medicine falling rapidly from the bottom of the tank from sinking too deep into the liquid surface, ensuring that the newly injected liquid medicine and emulsifier are all on the liquid surface, which facilitates subsequent mixing operations.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 11As shown, the present invention provides an emulsification device for pesticide suspensions, including a barrel 1 and a feeding pipe 12 and a discharge port 13 respectively installed at the top and bottom of the barrel 1. A cover 11 is installed on the top of the barrel 1. The device also includes a stirring mechanism 2 mounted on the barrel 1, a transmission mechanism 4 connected to the stirring mechanism 2 and mounted on the top of the cavity of the cover 11, and a cam 5 that can be driven and rotated by the transmission mechanism 4. An adjuvant adding mechanism 3 is installed on the top of the barrel 1; the adjuvant adding mechanism 3 includes a component fixed to the top of the cover 11. The storage tank 31 extends to the cover 11 and is connected to the feeding pipe 32. The bottom end of the feeding pipe 32 is an atomizing nozzle 34. The bottom of the feeding pipe 32 is provided with a one-way valve 35 that can unidirectionally flow downwards. The middle part of the feeding pipe 32 is provided with a one-way valve 36 that can unidirectionally flow into the feeding pipe 32. A spring piston rod 33 with an outward tendency is movably installed in the cavity at the top of the feeding pipe 32. One end of the spring piston rod 33 can abut against the outer periphery of the cam 5. The cam 5 is provided with a cross section 51.

[0037] When the cam 5 rotates, it can squeeze the spring piston rod 33 to block the connection between the feeding pipe 32 and the storage tank 31, and push out the emulsifier in the feeding pipe 32;

[0038] The stirring mechanism 2 includes a motor 21 fixedly installed at the bottom of the barrel 1. The output end of the motor 21 can extend into the cavity at the bottom of the barrel 1 and is connected to a stirring paddle 22. The stirring paddle 22 is rotatably connected to the barrel 1.

[0039] The end of the feed pipe 12 located inside the cover 11 is a hollow ring and is sleeved on the outer periphery of the shaft part of the stirring paddle 22. The bottom of the hollow ring of the feed pipe 12 is provided with several oblique holes 121.

[0040] Using the above scheme, the liquid medicine is input through the feeding pipe 12 and discharged through the inclined hole 121. The motor 21 drives the stirring paddle 22 to stir the liquid in the tank 1. At the same time, the stirring paddle 22 drives the cam 5 to rotate through the transmission mechanism 4. The cam 5 intermittently squeezes the spring piston rod 33 to first block the connection between the storage tank 31 and the feeding pipe 32. Then, the continued movement of the spring piston rod 33 will disperse the emulsifier in the feeding pipe 32 through the atomizing nozzle 34 and evenly fall into the liquid surface at the bottom of the tank 1, so as to achieve uniform addition of liquid medicine and emulsifier. During the medicine addition process, the medicine is mixed in layers evenly. At this time, the stirring paddle 22 does not need to be too fast to perform efficient emulsification and mixing.

[0041] When one end of the spring piston rod 33 passes the section 51, the spring piston rod 33 will move left and right toward the cam 5 and reset due to its own elastic force. At this time, the outside gas will enter the feeding pipe 12 through the one-way valve 36, and the emulsifier in the storage tank 31 will enter the feeding pipe 32 through its bottom for filling, so as to facilitate the next operation of the device.

[0042] like Figure 3 , Figure 6 and Figure 7 As shown, the transmission mechanism 4 includes a sun gear 41 fixedly sleeved on the top of the rod part of the stirring paddle 22, and several sets of fixed shafts 42 fixedly connected to the top of the cover 11 in a circular array. Planet gears 43 are rotatably connected to the outer periphery of the fixed shafts 42. An internal gear ring 44 is also provided on the top of the cavity of the cover 11. The bottom of the several fixed shafts 42 can support the bottom of the internal gear ring 44.

[0043] The sun gear 41 can mesh with a number of fixed shafts 42, and the number of fixed shafts 42 can mesh with the internal gear ring 44. The cam 5 is fixedly sleeved on the outer periphery of the internal gear ring 44.

[0044] By adopting the above scheme, the transmission mechanism 4 increases the speed reduction and torque of the stirring paddle 22 and drives the cam 5 to rotate, which can ensure that the cam 5 can stably push the spring piston rod 33 to move, and at the same time avoid the situation where the reciprocating speed of the spring piston rod 33 is too fast, resulting in the emulsifier being sprayed out of the atomizing nozzle 34 at too fast a speed.

[0045] like Figures 2-4 and Figures 6-9 As shown, an elastic diaphragm 6 located below the transmission mechanism 4 is fixedly installed at the bottom of the cavity of the cover 11. The feeding pipe 32 can pass through the elastic diaphragm 6, and the middle part of the elastic diaphragm 6 is movably sleeved on the outer periphery of the rod part of the stirring paddle 22. In the initial state, the elastic diaphragm 6 is an inverted funnel shape.

[0046] The top of the rod portion of the stirring paddle 22 is equipped with a vibration assembly 7 located below the transmission mechanism 4, which drives the elastic diaphragm 6 to continuously reciprocate in the vertical direction. The vibration assembly 7 includes a hollow column 71 movably sleeved on the top of the rod portion of the stirring paddle 22. A guide groove 72 is provided inside the hollow column 71. Several limiting columns 73 are fixedly connected to the top of the hollow column 71 in a circular array. The top of the limiting column 73 can pass upward through the fixed shaft 42 and extend to the top of the cover 11. The limiting column 73 is movably sleeved in the fixed shaft 42.

[0047] The middle part of the elastic diaphragm 6 is fixedly connected to the outer periphery of the hollow column 71; the top of the rod part of the stirring paddle 22 is fixedly connected to a convex shaft 221 that can slide in the guide groove 72; and a constant pressure hole 14 with a height higher than the elastic diaphragm 6 in the vertical direction is opened on the cover 11.

[0048] The guide groove 72 includes an upper arc groove 721 and a rubber scraper ring 711 formed on the hollow column 71. The top and bottom ends of the upper arc groove 721 are respectively connected to the top and bottom ends of the lower arc groove 722. The convex shaft 221 can slide in the upper arc groove 721 and the lower arc groove 722.

[0049] By adopting the above scheme, the elastic diaphragm 6 can prevent the dispersed drug particles in the barrel 1 from adhering to the transmission mechanism 4. The rotation of the stirring paddle 22 will drive the convex shaft 221 to rotate and slide in the guide groove 72. At this time, under the limiting action of the hollow column 71 and the fixed shaft 42, the hollow column 71 will reciprocate in the vertical direction. At the same time, the hollow column 71 will also drive the middle part of the elastic diaphragm 6 to reciprocate in the vertical direction, thereby preventing some of the dispersed drug molecules injected into the barrel 1 through the atomizing nozzle 34 and the oblique hole 121 from adhering to the elastic diaphragm 6. The opening of the constant pressure hole 14 can ensure the balance of gas pressure above the elastic diaphragm 6 in the cover 11.

[0050] like Figure 8 and Figure 9 As shown, a rubber scraper ring 711 is fixedly installed at the bottom of the hollow column 71, and the rubber scraper ring 711 is movably sleeved outside the rod part of the stirring paddle 22.

[0051] By adopting the above solution, the rubber scraper ring 711 follows the hollow column 71 back and forth in the vertical direction, which can prevent the dispersed particles in the barrel 1 from entering the upper part of the elastic diaphragm 6 through the gap between the hollow column 71 and the rod part of the stirring paddle 22.

[0052] like Figure 2 , Figure 3 , Figure 5 , Figure 10 and Figure 11 As shown, a vertical groove 222 is provided on the rod part of the agitator 22; a flow guiding assembly 8 is installed on the rod part of the agitator 22; the flow guiding assembly 8 includes a float 81 and a hollow cylinder 83 movably sleeved on the rod part of the agitator 22, a plurality of flexible flow guiding plates 84 are arranged in a ring array on the outer periphery of the hollow cylinder 83, the bottom of the hollow cylinder 83 is fixedly connected to the top of the float 81, a plurality of counterweights 82 are fixedly connected to the bottom of the float 81, a connector 85 is fixedly connected to the cavity of the hollow cylinder 83, and the connector 85 is movably installed in the vertical groove 222; the edges of two adjacent flexible flow guiding plates 84 can be located directly below the blade part of the agitator 22 at the joint;

[0053] Using the above scheme, during the process of injecting the liquid medicine and emulsifier into the tank 1, the medicine sprayed from the inclined hole 121 will hit the rod part of the stirring paddle 22 and fall onto the flexible guide plate 84 for dispersion. At this time, the presence of the flexible guide plate 84 can prevent the liquid medicine falling rapidly from the bottom of the tank 1 from going too deep into the liquid surface of the tank 1, ensuring that the newly injected liquid medicine and emulsifier are all on the liquid surface, which is convenient for subsequent mixing operations.

[0054] Working principle and usage process of this invention:

[0055] In use, the liquid medicine is fed into the feed pipe 12 and discharged through the inclined hole 121. The motor 21 drives the stirring paddle 22 to stir the liquid in the tank 1. At the same time, the stirring paddle 22 drives the cam 5 to rotate through the transmission mechanism 4. The cam 5 intermittently squeezes the spring piston rod 33 to first block the connection between the storage tank 31 and the feed pipe 32. Then, the continued movement of the spring piston rod 33 will disperse the emulsifier in the feed pipe 32 through the atomizing nozzle 34 and evenly fall into the liquid surface at the bottom of the tank 1, so as to achieve uniform addition of liquid medicine and emulsifier, thereby improving mixing efficiency and mixing effect.

[0056] The rotation of the stirring paddle 22 will drive the convex shaft 221 to rotate and slide in the guide groove 72. At this time, under the limiting action of the hollow column 71 and the fixed shaft 42, the hollow column 71 will reciprocate in the vertical direction. At the same time, the hollow column 71 will also drive the middle part of the elastic diaphragm 6 to reciprocate in the vertical direction, thereby avoiding the situation that some of the diffused drug molecules injected into the barrel 1 from the atomizing nozzle 34 and the oblique hole 121 will adhere to the elastic diaphragm 6.

[0057] During the process of injecting the liquid medicine and emulsifier into the tank 1, the medicine sprayed from the inclined hole 121 will hit the rod part of the stirring paddle 22 and fall onto the flexible guide plate 84 for dispersion. At this time, the presence of the flexible guide plate 84 can prevent the liquid medicine falling rapidly from the bottom of the tank 1 from going too deep into the liquid surface of the tank 1, ensuring that the newly injected liquid medicine and emulsifier are all on the liquid surface, which is convenient for subsequent mixing operations.
