Technical Field

[0001] This utility model relates to the technical field of pesticide intermediate processing equipment, specifically to a mixing device for pesticide intermediate processing. Background Technology

[0002] Pesticide intermediates are intermediate compounds that are synthesized from active ingredients into the final product during pesticide production. They are a crucial link in the pesticide production chain. The processing of pesticide intermediates typically involves mixing different pesticide raw materials together and stirring them to ensure proper mixing. However, this mixing process often produces solid impurities that can negatively impact subsequent processing and the efficacy of the final pesticide product. Utility Model Content

[0003] This application provides a mixing device for processing pesticide intermediates, which can solve the problem that some solid impurities are easily generated when different pesticide raw materials are mixed together, affecting the subsequent processing effect.

[0004] This application provides a mixing device for processing pesticide intermediates, including a mixing tank, which is a hollow tank. The mixing tank has an inlet at the upper end and an openable outlet at the lower end. A stirring structure is rotatably installed in the mixing tank, with its rotating shaft in the vertical direction, for mixing pesticide raw materials by stirring. A first motor is provided to drive the stirring structure to rotate. A vertically penetrating mounting pipe is connected to the lower end of the mixing tank. A filter screen is detachably installed in the mounting pipe for filtering the pesticide intermediate discharged from the outlet to remove impurities.

[0005] In one embodiment, an opening and closing cover is hinged at the discharge port, with its rotating shaft in the horizontal direction and a second motor for driving its rotation, thereby realizing the opening and closing of the discharge port.

[0006] In one embodiment, the stirring structure includes a connecting rod that is rotatably arranged vertically. The first motor is mounted downwards on the upper end of the mixing tank. The upper end of the connecting rod is fixedly connected to the output shaft of the first motor, and the lower end of the connecting rod is located inside the mixing tank.

[0008] In one embodiment, an inwardly opening mounting groove is provided on the side of the mounting tube, and the filter plate is slidably connected to the mounting groove in the horizontal direction, so as to enable the filter plate to be detachable by sliding into or out of the mounting tube through the mounting groove.

[0009] In one embodiment, the filter plate is provided with a first through hole, and the mounting tube is provided with a corresponding first threaded hole and a first bolt, so that the filter plate can be fixed or unfixed by means of threaded connection.

[0010] In summary, the mixing apparatus for processing pesticide intermediates disclosed in this application has the following advantages compared to the prior art:

[0011] (1) The pesticide raw materials are stirred and mixed in the mixing tank by the stirring structure, and then the stirred pesticide intermediate is filtered through the filter screen to remove impurities, which can improve the effect of subsequent processing and final product.

[0021] Please see Figure 1 A mixing device for processing pesticide intermediates includes a mixing tank 1, which is a cylindrical hollow tank. The mixing tank 1 has an inlet 2 at its upper end for adding pesticide raw materials. The number of inlets 2 can be determined according to actual needs. The mixing tank 1 has an openable outlet 3 at its lower end for discharging the pesticide intermediates after mixing.

[0022] Please see Figure 1 , Figure 2 , Figure 3 The mixing tank 1 is equipped with a stirring structure 6, whose rotating shaft is in the vertical direction, for mixing pesticide raw materials by stirring, and is equipped with a first motor 9 for driving the stirring structure 6 to rotate.

[0023] Please see Figure 1 , Figure 3 The lower end of the mixing tank 1 is connected to an installation pipe 10 that runs vertically through it. The installation pipe 10 is a square pipe and is fixedly connected to the mixing tank 1 by welding. A filter screen 12 is detachably installed in the installation pipe 10 to filter the pesticide intermediate discharged from the outlet 3 to remove impurities. The filter screen 12 can also be removed and cleaned periodically to maintain a good filtration effect.

[0024] Please see Figure 3, Figure 4 In one embodiment, a hinged cover 4 is hinged at the discharge port 3, with its rotating shaft in a horizontal direction. A second motor 5 is provided to drive its rotation. The housing of the second motor 5 is fixedly connected to the inner wall of the mounting tube 10 by threaded connection or welding, and its output shaft is fixedly connected to the rotating shaft of the hinged cover 4 by welding. When the cover is rotated to a horizontal position, it can completely cover the discharge port 3 at the lower end of the mixing tank 1 and maintain a good sealing effect, preventing liquid leakage from the mixing tank 1. This can be achieved by conventional technical means (such as sealing gaskets), which will not be described in detail here. With this configuration, the discharge port 3 can be opened and closed by rotating the hinged cover 4, which is structurally reasonable and has a stable effect.

[0025] Please see Figure 3 In one embodiment, the stirring structure 6 includes a connecting rod 7, which is vertically rotatably mounted at the central axis of the mixing tank 1 and located on the upper side. The first motor 9 is fixedly mounted downwards on the top surface of the mixing tank 1, and its output shaft extends downwards through the mixing tank 1 into its interior. The upper end of the connecting rod 7 is fixedly connected to the output shaft of the first motor 9 by welding, and the lower end of the connecting rod 7 is located inside the mixing tank 1. An L-shaped rod 8 is welded and fixedly mounted on the connecting rod 7. The horizontal part of the L-shaped rod 8 is fixedly connected to the side of the lower end of the connecting rod 7, and the vertical part of the L-shaped rod 8 extends downwards to stir the pesticide raw materials in the mixing tank 1 through its vertical part under the drive of the first motor 9, so as to mix them. This configuration allows for better mixing through the rotation of the vertical portion of the L-shaped rod 8 around the central axis of the mixing tank 1. Furthermore, after mixing, the L-shaped rod 8 continues to rotate during discharge, easily forming a small vortex at the center of the mixing tank 1. This facilitates the downward discharge of the mixed pesticide intermediate, effectively preventing blockage. Additionally, there are two L-shaped rods 8, located on opposite sides of the connecting rod 7, further enhancing the mixing effect.

[0026] Please see Figure 1 , Figure 3 , Figure 4In one embodiment, the mounting tube 10 has a mounting groove 11 extending inward along a horizontal direction on its side. The filter plate 12 is slidably connected to the mounting groove 11 in a horizontal direction, allowing it to slide into or out of the mounting tube 10 via the mounting groove 11. This design makes the filter plate 12 detachable, making the structure easier to implement and operate. Furthermore, the filter plate 12 has multiple first through holes 13, and the mounting tube 10 has the same number of first threaded holes 14 at corresponding positions, along with multiple first bolts 15. When the filter plate 12 is inserted into the mounting groove 11, each first bolt 15 can pass through one of the first through holes 13 and be screwed into one of the first threaded holes 14. This threaded connection allows for the fixing or unfixing of the filter plate 12, making the structure more stable.
