Description

Technical Field

[0001] This utility model relates to the field of pesticide production mixing technology, and in particular to a mixing device for preparing liquid formulations. Background Technology

[0002] In the field of pesticide production technology, the production process of various liquid formulations, such as emulsifiable concentrates, aqueous solutions, and suspensions, all require the use of a mixing tank. The typical procedure involves adding the materials to the mixing tank, mixing them thoroughly using a stirring paddle, and then packaging them. However, different materials have different requirements regarding the length of the stirring paddle.

[0003] Existing mixing paddles have significant limitations in practical use. Their blades have a fixed length and are mounted on a ring, which is then fixed to the motor's output shaft. Rotation of the motor's output shaft drives the ring and blades to rotate together. Because pesticides and feedstocks vary in density and viscosity, mismatches between the paddle length and the material properties can lead to uneven mixing. To address this issue, companies often need to equip multiple mixing tanks with different blade lengths and motors of varying power. This not only results in excessive equipment investment but also increases production costs. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1:

[0030] Reference Figures 1-5 A stirring device for preparing liquid formulations, comprising:

[0031] A stirring vessel 2 with a lid 201 attached to its top;

[0032] Stirring rod 3 is rotatably connected to the kettle cover 201;

[0033] The connecting sleeve 4 is detachably connected to the stirring rod 3. Multiple sets of fixed blades 5 are fixedly connected to the connecting sleeve 4, and movable blades 6 are connected to the fixed blades 5.

[0034] Multiple sets of first mounting holes 602 are evenly distributed on the movable blade 6;

[0035] A first screw 8 is threadedly connected to the fixed blade 5, and the first screw 8 is threadedly connected to the first mounting hole 602.

[0036] It should be noted that the spacing between two adjacent sets of first mounting holes 602 is equal.

[0037] Reference Figure 1 , Figure 3The lid 201 is connected to a drive motor 1 and a reducer 101. The reducer 101 is connected to the drive end of the drive motor 1, and the stirring rod 3 is connected to the drive end of the reducer 101.

[0038] In practical implementation, drive motor 1 is a commercially available variable frequency motor, specifically the FMWB150-59-YVP variable frequency motor, and reducer 101 is a commercially available KF97 reducer.

[0039] Variable frequency motors can directly adjust their operating power based on changes in the length of the agitator blades and the actual resistance during material mixing. While meeting the process requirements for agitator blade length, the motor operates at minimum power, avoiding unnecessary energy consumption and achieving significant energy savings, thus optimizing production and operating costs.

[0040] The fixed blade 5 has a threaded hole 504, which is threadedly connected to the first screw 8. A limit hole 503 is fixedly connected in the fixed blade 5, and the limit hole 503 is located directly below the threaded hole 504.

[0041] A magnet 9 is fixedly connected in the limiting hole 503. The first screw 8 is an iron rod, and the bottom of the first screw 8 is attracted to the magnet 9.

[0042] Reference Figure 5 After the first screw 8 is tightened, the bottom of the first screw 8 will be screwed into the limiting hole 503, and at this time the bottom of the first screw 8 will be attracted to the magnet 9 in the limiting hole 503. The magnet 9 attracts the first screw 8, thereby improving the stability of the first screw 8 after tightening, reducing the possibility of the first screw 8 loosening due to stirring vibration, and ensuring its fixed stability to the movable blade 6.

[0043] A sealing ring 502 is fixedly connected to the fixed blade 5, and the sealing ring 502 is in contact with the first screw 8.

[0044] Reference Figure 5 The fixed blade 5 has a mounting groove 501 that matches the movable blade 6. When the movable blade 6 is inserted into the mounting groove 501, the side wall of the movable blade 6 is in contact with the inner side wall of the mounting groove 501.

[0045] Reference Figure 5 By fixing the sealing ring 502 connected to the blade 5, the movable blade 6 is installed in the mounting groove 501. When the first screw 8 is tightened, the sealing ring 502 will fill the gap between the top of the first screw 8 and the threaded hole 504. During the stirring operation, it can effectively prevent the stirring material from entering the mounting groove 501.

[0046] The bottom of the stirring rod 3 is fixedly connected to the mounting rod 301, and the connecting sleeve 4 has a second mounting hole 401 that matches the mounting rod 301.

[0047] A limiting rod 302 is fixedly connected to the side wall of the mounting rod 301, and a limiting groove 402 is opened on the connecting sleeve 4, which matches the limiting rod 302.

[0048] The mounting rod 301 has a connecting hole 3011 at the bottom, and a second screw 701 is threaded into the connecting hole 3011. A pressure plate 7 is fixedly connected to the bottom of the second screw 701, and the pressure plate 7 abuts against the connecting sleeve 4.

[0049] An arc-shaped surface 601 is provided on the movable blade 6.

[0050] Reference Figure 4 The arc-shaped surface 601 on the movable blade 6 effectively reduces the stirring resistance during stirring.

[0051] Reference Figures 3-6 When it is necessary to adjust the installation length of the movable blade 6, the staff unscrews the first screw 8 and pulls out the movable blade 6. When the movable blade 6 is pulled out to the appropriate installation length, the first mounting hole 602 and the threaded hole 504 on the movable blade 6 are aligned, and the first screw 8 is screwed into the threaded hole 504 to complete the fixing of the movable blade 6.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
