Description

Technical Field

[0001] This utility model belongs to the field of pesticide raw material mixing technology, and in particular relates to a pesticide preparation raw material mixing reaction vessel. Background Technology

[0002] In the pesticide production process, the raw material mixing reactor is one of the core pieces of equipment in the entire process. Its core function is to achieve uniform dispersion and full contact of multiple components such as pesticide technical, solvent, and adjuvants through mechanical stirring.

[0003] Currently, most existing reaction vessels use a single stirring paddle or a simple multi-paddle structure, resulting in a single stirring method. The movement trajectory of the stirring paddle is limited to the reciprocating rotation in the central area of ​​the vessel. The shear force distribution is uneven and the coverage is limited, which cannot effectively drive the material near the vessel wall and bottom to participate in the mixing. This leads to a stratification phenomenon of "sufficient mixing in the center and stagnation and accumulation at the edges," resulting in insufficient uniformity of pesticide raw material mixing and large batch-to-batch quality fluctuations. This not only reduces the reaction conversion rate and formulation stability but also increases the cost of subsequent separation and purification.

[0004] To address the aforementioned issues, this application proposes a pesticide preparation raw material mixing reactor. Utility Model Content

[0005] The purpose of this invention is to provide a pesticide preparation raw material mixing reactor, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a pesticide preparation raw material mixing reactor, comprising a reactor body and multiple sets of stirring rods, which are longitudinally arranged on the outside of a rotating shaft rotatably mounted inside the reactor body. Each set of stirring rods includes multiple main stirring rods arranged circumferentially. A horizontal rod is circumferentially fixed to the outer wall of the upper end of the rotating shaft, and a vertical rod rotatably connected to one end of a main stirring rod is fixed to the bottom end of the horizontal rod. The rotating shaft drives the main stirring rods to revolve around the rotating shaft. Multiple bevel gears are longitudinally fixed to the outer wall of a fixed sleeve, and the bottom end of the fixed sleeve is fixedly connected to the bottom plate of the reactor body. A second bevel gear fixed to the end of the main stirring rod in the same set meshes with the same first bevel gear. Secondary stirring rods are uniformly fixed to the outer wall of the main stirring rods. The rotation of the main stirring rods is driven by the transmission of the second and first bevel gears.

[0008] Furthermore, the adjacent bevel gears are mirror-symmetrical.

[0009] Furthermore, the outer wall of the fixed sleeve is connected to multiple protective components, and bevel gear one and bevel gear two are disposed inside the protective components. The protective components include a rotating ring and two fixed rings fixedly connected to the outer wall of the fixed sleeve. The rotating ring is rotatably installed between the two fixed rings, and the main stirring rod passes through the side wall of the rotating ring and is rotatably connected to the rotating ring.

[0010] Furthermore, a motor with its output end fixedly connected to the rotating shaft is fixedly installed at the top of the vessel body, and a spiral blade is fixedly installed on the outer wall of the rotating shaft, with the spiral blade located inside the fixed sleeve. The upper and lower ends of the fixed sleeve are respectively provided with a feed port and a discharge port.

[0011] Furthermore, a rotating sleeve is rotatably mounted on the top plate of the vessel body. The lower outer wall of the rotating sleeve is fixedly connected to the inner ring of the bearing, the upper inner wall of the fixed sleeve is fixedly connected to the outer ring of the bearing, and the horizontal rod passes through the outer wall of the rotating sleeve and is fixedly connected to the rotating sleeve.

[0012] Furthermore, the inner wall of the fixing sleeve is fitted to the outer wall of the scraper rod, and the scraper rod is fixedly connected to the vertical rod through the fixing block.

[0013] Furthermore, the top and bottom of the vessel are respectively connected to a feed pipe and a discharge pipe, and valves are installed on both the feed pipe and the discharge pipe.

[0014] This utility model has the following beneficial effects:

[0015] This invention uses a rotating shaft to drive the horizontal and vertical rods to rotate, thereby driving all the main stirring rods to rotate around the rotating shaft, forming a large-scale stirring trajectory covering the axial and radial directions of the vessel body, significantly expanding the mixing coverage area;

[0016] When the main stirring rod of this invention rotates around the rotating shaft, the second bevel gear and the first bevel gear are driven together, forcing the main stirring rod to revolve around the central axis and rotate on its own axis at the same time, driving the auxiliary stirring rod to rotate, forming a "revolution + rotation" compound stirring mode, which can not only further improve the stirring coverage, but also improve the degree of mixing and refinement of the raw materials.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figure 1 - Figure 4As shown, this utility model is a pesticide preparation raw material mixing reaction vessel, including a vessel body 1 and multiple sets of stirring rod groups 6, which are longitudinally arranged outside a rotating shaft 3 rotatably installed inside the vessel body 1. Each set of stirring rod groups 6 includes multiple main stirring rods 7 arranged circumferentially. A horizontal rod 301 is fixedly fixed circumferentially on the outer wall of the upper end of the rotating shaft 3, and a vertical rod 302 rotatably connected to one end of the main stirring rod 7 is fixedly fixed at the bottom end of the horizontal rod 301. The rotating shaft 3 drives the main stirring rod 7 to revolve around the rotating shaft 3. Multiple bevel gears 8 are longitudinally fixed on the outer wall of a fixed sleeve 5. The bottom end of the fixed sleeve 5 is fixedly connected to the bottom plate of the vessel body 1. The bevel gears 9 fixed at the ends of the main stirring rods 7 in the same group mesh with the same bevel gear 8. Auxiliary stirring rods 10 are uniformly fixed on the outer wall of the main stirring rods 7. The rotation of the main stirring rods 7 is driven by the transmission of the bevel gears 9 and 8.

[0028] This embodiment provides a pesticide preparation raw material mixing reactor. When the rotating shaft 3 rotates, the horizontal rod 301 drives the vertical rod 302 to rotate, which in turn drives the main stirring rod 7 to revolve around the rotating shaft 3. The arrangement of multiple stirring rod groups 6 can perform large-scale, dead-angle-free preliminary mixing of the raw materials in the reactor, effectively covering the axial and radial areas, avoiding the mixing blind spots that exist in traditional single-point or multi-point stirring, and improving the overall mixing uniformity. When the main stirring rod 7 revolves around the rotating shaft 3, it achieves its own rotation through the transmission of bevel gear 1 8 and bevel gear 2 9. The auxiliary stirring rods 10, which are evenly distributed on its outer wall, rotate synchronously with the main stirring rod 7, forming a "revolution + rotation" composite stirring mode, which increases the stirring dimension. The radial stirring of the rotation further refines the dispersion and mixing of local materials, which is especially suitable for the uniform dispersion of high viscosity or large particle raw materials, avoiding material stratification or agglomeration.

[0029] The adjacent bevel gears 8 are mirror-symmetrical. The mirror-symmetrical arrangement of the bevel gears 8 causes the main stirring rods 7 of adjacent stirring rod groups 6 to rotate in opposite directions. That is, the main stirring rods 7 of one stirring rod group 6 rotate clockwise, while the main stirring rods 7 of the adjacent stirring rod groups 6 rotate counterclockwise, forming convective shear force, avoiding mixing dead zones and improving dispersion efficiency.

[0030] The outer wall of the fixed sleeve 5 is connected to multiple protective components 11, and bevel gear 8 and bevel gear 9 are disposed inside the protective components 11. The protective components 11 include a rotating ring 1102 and two fixed rings 1101 fixedly connected to the outer wall of the fixed sleeve 5. The rotating ring 1102 is rotatably installed between the two fixed rings 1101. The main stirring rod 7 passes through the side wall of the rotating ring 1102 and is rotatably connected to the rotating ring 1102. The protective components 11 isolate the material from the gears and prevent the material from affecting the transmission effect of bevel gear 8 and bevel gear 9.

[0031] The top of the vessel body 1 is fixed with a motor 2 whose output end is fixedly connected to the rotating shaft 3. The outer wall of the rotating shaft 3 is fixed with a spiral blade 4, and the spiral blade 4 is located inside the fixed sleeve 5. The upper end and the lower end of the fixed sleeve 5 are respectively provided with a feed port 501 and a discharge port 502. The rotating shaft 3 drives the spiral blade 4 to rotate, and the material at the bottom is transported to the discharge port 502 through the feed port 501 and discharged. The material at the bottom is lifted to the top and redispersed, forming a vertical convection circulation. The circulation flow accelerates the material exchange rate and avoids local over-stirring or mixing blind spots.

[0032] The top plate of the vessel body 1 is rotatably mounted with a rotating sleeve 13. The lower outer wall of the rotating sleeve 13 is fixedly connected to the inner ring of the bearing 14. The upper inner wall of the fixed sleeve 5 is fixedly connected to the outer ring of the bearing 14. The horizontal rod 301 passes through the outer wall of the rotating sleeve 13 and is fixedly connected to the rotating sleeve 13.

[0033] The inner wall of the fixed sleeve 5 is in contact with the outer wall of the scraper 12, and the scraper 12 is fixedly connected to the vertical rod 302 through the fixing block 1201. When the vertical rod 302 revolves with the rotating shaft 3, the scraper 12 rotates synchronously to scrape off the material attached to the inner wall of the fixed sleeve 5 and avoid material residue.

[0034] The top and bottom of the vessel body 1 are respectively connected to a feed pipe 101 and a discharge pipe 102, and valves are installed on both the feed pipe 101 and the discharge pipe 102. The feed pipe 101 is used for feeding materials, and the discharge pipe 102 is used for discharging mixed products.

[0035] It is understood that this utility model uses the main stirring rod 7 to stir the materials in the vessel 1 over a wide range, thereby improving the mixing uniformity of pesticide raw materials. Secondly, the rotation of the auxiliary stirring rod 10 generates local high shear force, which further improves the mixing uniformity of pesticide raw materials.

[0036] A specific application of the operation process in this embodiment is as follows: Raw materials are fed into the vessel 1 through the feed pipe 101. The motor 2 is started to drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 simultaneously drives the horizontal rod 301 and the spiral blade 4 to rotate. The rotation of the horizontal rod 301 drives the main stirring rod 7 to rotate through the vertical rod 302, so that the main stirring rod 7 can stir and mix the raw materials in the vessel 1 over a large area. When the main stirring rod 7 rotates around the rotating shaft 3, it drives the main stirring rod 7 to rotate by the transmission action of the first bevel gear 8 and the second bevel gear 9. The auxiliary stirring rod 10 rotates synchronously with the main stirring rod 7, which not only further expands the stirring area, but also forms a "revolution + rotation" compound stirring mode with the rotation of the main stirring rod 7, which increases the dimension of stirring. The spiral blade 4 can axially transport the material. When rotating, it drives the material that has sunk to the bottom of the vessel 1 to be transported back to the top, so that the material can be dispersed again and achieve uniform mixing throughout the entire area.
