Description

Technical Field

[0001] This application relates to the field of mixing equipment technology, specifically a mixing device for an anti-precipitation pesticide emulsifier. Background Technology

[0002] The production of pesticide emulsifiers requires the uniform mixing of multiple components such as solvents, active ingredients, and emulsifying agents. However, the mixing process is prone to precipitation problems due to the characteristics of the components and the stirring method.

[0003] However, the density differences between different components are significant. For example, the density of active ingredients is often greater than that of solvents, and emulsifiers need to be thoroughly stirred to form a stable dispersion system. If the dispersed phase particles are not effectively dispersed, they are prone to agglomeration and sedimentation due to gravity. Secondly, most existing mixing devices use a single stirring shaft, which is usually suspended inside the tank. There is a large gap between its bottom end and the bottom end of the tank, and its stirring range is limited. It is not possible to effectively agitate the material at the bottom of the tank, nor is it possible to ensure that the hydrophilic or lipophilic groups of the emulsifier are uniformly adsorbed on the surface of the dispersed phase to form a stable emulsion film, which ultimately leads to uneven mixing of materials. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a mixing device for anti-precipitation pesticide emulsifiers, which has advantages such as anti-precipitation and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a mixing device for an anti-settling pesticide emulsifier, comprising a tank, wherein a stirring tube is rotatably connected between the top and bottom ends of the tank, and a support ring is fixedly connected to the bottom end of the tank and is coaxially arranged therewith;

[0006] The support ring is rotatably connected to a closed cylinder coaxially arranged with the tank body. The closed cylinder is radially inclined and rotatably connected to a set of bottom stirring shafts. Bottom stirring blades are fixedly installed on the outer surface of each bottom stirring shaft. The closed cylinder is fixedly connected to the stirring tube.

[0007] Furthermore, a set of main stirring blades are fixedly connected to the middle and top of the stirring tube, and the bottom end of the stirring tube is connected to the output end of an external power source to drive the stirring tube to rotate.

[0008] The above method enables synchronous stirring of materials at different heights in the tank, thereby improving the uniformity of material mixing.

[0009] Furthermore, a set of return pipes is fixedly connected to the top of the tank, an adsorption port is opened on the bottom circumferential surface of the stirring tube, a pump body is installed above the top of the stirring tube, the input end of the pump body is connected to the top of the stirring tube through a rotary joint, and the output end of the pump body is fixedly connected to a flow divider box. A set of connection ports is fixedly connected to the outer surface of the flow divider box, and the connection ports are connected to the corresponding return pipes through external pipelines.

[0010] Through the above scheme, during the mixing process, the pump body can draw up the material that is easy to settle at the bottom, and after passing through the mixing pipe, pump body and distribution box, it is transported to the top of the tank through the return pipe, so as to further realize the circulation and mixing of materials, avoid local material sedimentation, and further improve the mixing effect.

[0011] Furthermore, a set of support legs for supporting the tank are fixedly installed on the outer surface of the tank, and a gap is provided between the bottom of the tank and the bottom end of the support legs for installing an external motor.

[0012] The above solution facilitates the power connection between the external motor and the bottom of the mixing tube, while avoiding interference caused by direct contact between the motor and the ground.

[0013] Furthermore, a feed valve pipe and a discharge valve pipe are respectively installed at the top and bottom of the tank.

[0014] With the above scheme, the feed valve pipe is used to add materials into the tank, and the discharge valve pipe is used to discharge the mixed pesticide emulsion.

[0015] Furthermore, the stirring tube is made of 304 stainless steel.

[0016] The above solution ensures mechanical strength while meeting the corrosion resistance requirements of pesticide emulsifiers, thus extending the service life of the equipment.

[0017] Furthermore, the support ring is fixedly connected to a coaxially arranged bevel gear ring, and each end of the stirring shaft located inside the closed cylinder is fixedly connected to a bevel gear, and each bevel gear is meshed with the bevel gear ring.

[0018] With the above scheme, when the stirring tube rotates, it drives the closed cylinder to rotate. The closed cylinder drives the bottom stirring shaft to revolve. During the revolution, the stirring shaft rotates on its own axis, which can fully disperse the material deposited at the bottom and push it to the middle of the tank to mix with the material at the top, further enhancing the anti-sedimentation effect.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0020] The mixing device for this anti-settling pesticide emulsifier uses a coaxially rotating stirring tube inside the tank, with stirring blades installed in the middle and top of the stirring tube, to achieve synchronous stirring of the materials in the main areas of the tank, ensuring the uniformity of material mixing. When the stirring tube rotates, it drives the bottom stirring shaft to revolve. The stirring shaft rotates by meshing with a bevel gear and a bevel gear ring, which can fully disperse the material deposited at the bottom and push it to the middle of the tank to mix with the material at the top.

[0021] By utilizing the adsorption port, pump body, diversion box, and return pipe at the bottom of the stirring tube, materials that are prone to sedimentation at the bottom can be sucked up during the stirring process and transported to the top of the tank, realizing the circulation and mixing of materials, avoiding local material sedimentation, and further improving the mixing effect.

[0030] Please see Figures 1-5This embodiment discloses a mixing device for an anti-settling pesticide emulsifier, comprising a tank 1. An inlet valve pipe 14 and a outlet valve pipe 15 are respectively installed at the top and bottom of the tank 1. The inlet valve pipe 14 is used to add materials into the tank 1, and the outlet valve pipe 15 is used to discharge the mixed pesticide emulsifier. A coaxial stirring pipe 2 is rotatably connected between the top and bottom of the tank 1. The stirring pipe 2 is made of 304 stainless steel, ensuring mechanical strength while meeting the corrosion resistance requirements of the pesticide emulsifier, thus extending the service life of the device. A coaxial stirring pipe is fixedly connected to the bottom of the tank 1. The set support ring 3, the middle and top of the stirring tube 2 are fixedly connected to a set of stirring blades 7, the bottom end of the stirring tube 2 is connected to the output end of the external power source, which is used to drive the stirring tube 2 to rotate, realize the synchronous stirring of materials at different heights in the tank 1, and improve the uniformity of material mixing. A set of support legs 13 are fixedly installed on the outer surface of the tank 1 for supporting it. A gap is set between the bottom of the tank 1 and the bottom end of the support legs 13 for installing an external motor, which facilitates the power connection between the external motor and the bottom end of the stirring tube 2, and avoids interference caused by direct contact between the motor and the ground.

[0031] A support ring 3 is rotatably connected to a closed cylinder 4 coaxially arranged with the tank body 1. The closed cylinder 4 prevents material contamination at the connection between the stirring pipe 2 and the tank body 1, ensuring the sealing and cleanliness of the internal components and preventing interference with the internal transmission structure. A set of bottom stirring shafts 5 are rotatably connected to the radially inclined closed cylinder 4. Bottom stirring blades 6 are fixedly installed on the outer surface of each bottom stirring shaft 5. The closed cylinder 4 is fixedly connected to the stirring pipe 2. The bottom stirring blades 6 can stir the material at the bottom of the tank body 1. During rotation, they continuously stir the bottom material... The material is turned upwards, and with the horizontal stirring above, the material is fully mixed. The support ring 3 is fixedly connected to a coaxially arranged conical tooth ring 16. Each end of the stirring shaft located inside the closed cylinder 4 is fixedly connected to a conical gear 17. Each conical gear 17 is meshed with the conical tooth ring 16. When the stirring tube 2 rotates, it drives the closed cylinder 4 to rotate. The closed cylinder 4 drives the bottom stirring shaft 5 to revolve. The stirring shaft rotates on its own axis during the revolution, which can fully disperse the material deposited at the bottom and push it to the middle of the tank 1 to mix with the material above, further enhancing the anti-sedimentation effect.

[0032] A set of return pipes 8 are fixedly connected to the top of the tank body 1. An adsorption port 9 is opened on the circumferential surface of the bottom end of the stirring pipe 2. A pump body 10 is set above the top of the stirring pipe 2. The input end of the pump body 10 is connected to the top of the stirring pipe 2 through a rotary joint. The output end of the pump body 10 is fixedly connected to a diversion box 11. A set of connection ports 12 are fixedly connected to the outer surface of the diversion box 11. The connection ports 12 are connected to the corresponding return pipes 8 through external pipelines. During the stirring process, the pump body 10 can suck up the material that is easy to settle at the bottom. After passing through the stirring pipe 2, the pump body 10 and the diversion box 11, it is transported to the top of the tank body 1 through the return pipe 8 to further realize the circulation and mixing of materials, avoid local material sedimentation, and further improve the mixing effect.

[0033] The working principle of the above embodiment is as follows: Through the feed valve pipe 14 installed at the top of the tank 1, multi-component materials such as solvent, active ingredients, and emulsifying agents are added into the tank 1 to prepare for subsequent mixing and stirring. The bottom end of the stirring pipe 2 is connected to the output end of an external power source. After the power source is started, it drives the stirring shaft to rotate. Since the stirring pipe 2 is connected to the stirring shaft, it drives the stirring pipe 2 to rotate coaxially between the top and bottom ends of the tank 1. A set of stirring blades 7 are fixedly connected to the middle and top of the stirring pipe 2. During the rotation of the stirring pipe 2, the stirring blades 7 rotate accordingly, and the materials at different heights of the tank 1 are stirred synchronously, so that the materials in the main area of ​​the tank 1 can be initially mixed under the action of the stirring blades 7, thereby improving the uniformity of material mixing. A support ring 3 is fixedly connected to the bottom end of the tank 1 and is coaxially arranged. The support ring 3 is rotatably connected to a closed cylinder 4 that is coaxially arranged with the tank 1, and the closed cylinder 4 is fixedly connected to the stirring pipe 2. When the stirring pipe 2 rotates, it will drive the closed cylinder 4 to rotate together. A set of bottom stirring shafts 5 are radially inclined and rotatably connected to the closed cylinder 4. Bottom stirring blades 6 are fixedly installed on the outer surface of each bottom stirring shaft 5. The rotation of the closed cylinder 4 drives the bottom stirring shafts 5 to revolve. A coaxially arranged bevel gear ring 16 is fixedly connected to the support ring 3. A bevel gear 17 is fixedly connected to one end of each stirring shaft located inside the closed cylinder 4. Each bevel gear 17 is meshed with the bevel gear ring 16. During the revolution of the bottom stirring shaft 5, due to the meshing action of the bevel gear 17 and the bevel gear ring 16, the bottom stirring shaft 5 rotates on its own axis while revolving around the center. Driven by the bottom stirring shaft 5, the bottom stirring blades 6 fully disperse the material deposited at the bottom and push it to the middle and upper parts of the tank 1 for further mixing with the material being stirred at the top. This effectively prevents the bottom material from settling and enhances the anti-settling effect. The bottom circumferential surface of the stirring tube 2 is provided with an adsorption port 9. During the stirring process, the material that is prone to settling at the bottom of the tank 1 will enter the interior of the stirring tube 2 through the adsorption port 9. A pump body 10 is provided at the top of the stirring tube 2, and the input end of the pump body 10 is connected to the top of the stirring tube 2 through a rotary joint. After the pump body 10 is started, it draws out the material sucked from the bottom of the stirring tube 2 and delivers it to the fixedly connected diversion box 11 through the output end of the pump body 10. A set of connection ports 12 are fixedly connected to the outer surface of the diversion box 11. The connection ports 12 are connected to the corresponding return pipe 8 through the external pipeline. The return pipe 8 is fixedly connected to the top of the tank body 1. Therefore, the material coming out of the diversion box 11 will be delivered to the top of the tank body 1 through the return pipe 8 to realize the circulation and mixing of the material, avoid local material sedimentation, and further improve the mixing effect.
