[0002] Modern liquid fertilizers include fertilizers in solution and suspensions containing solid particles, such as liquid ammonia, ammonia water, carbonated ammonia water, and mixed aqueous solutions (or suspensions) containing nitrogen fertilizers, phosphate fertilizers, and potash fertilizers (or salts).

[0003] In the modern production process of liquid fertilizers, proportioning and mixing is the most common production method. However, in the production and mixing process of modern liquid fertilizers, mixing kettles are mainly used for mixing and proportioning. At present, mixing kettles often use auger rotation to mix during mixing. However, since the auger only performs rotational motion during the mixing process, it is necessary to maintain axial stability, but the material only rotates in one direction, the mixing efficiency is often very low, and it is easy to cause insufficient mixing. In view of this, in-depth research on the above problems has led to the creation of this case. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-3 The utility model provides an implementation scheme: In the modern liquid fertilizer production process, liquid fertilizer is often produced by mixing. However, during the production process, only the shear force generated by the rotation of a single auger during mixing makes it impossible to improve the mixing efficiency of the liquid material. If only the auger mixing method is used, if you want to improve the mixing efficiency, you can only improve the efficiency of the mixing motor, which further increases the power demand for the motor.

[0022] According to the instruction manual Figure 1-3 It can be seen that in response to the above problems, the present application discloses an efficient batching machine for liquid fertilizer production, with a mixing machine casing 1 as the main structure of the batching machine, and a top cover 2 is provided on the top of the mixing machine casing 1.

The plurality of supporting legs 5 play a supporting role for the mixing machine casing 1 and raise the height of the mixing machine casing 1;

[0023] According to the instruction manual Figure 1-3 It can be seen that a rotating shaft seat 6 is provided at the center of the top cover 2 of the mixer housing 1. The rotating shaft seat 6 is placed at the center of the top cover 2 and serves as a central mounting. A rotating motor 7 is provided on the rotating shaft seat 6. A gear box 8 is connected to the driving end of the rotating motor 7. The rotating motor 7 can drive the gear box 8 to rotate, thereby utilizing the deceleration effect of the gear box 8 to increase the output torque.

[0024] Furthermore, a mixing shaft 9 is assembled in the mixing housing 1. The end of the mixing shaft 9 is connected to the output end of the gear box 8. A mixing blade 10 is sleeved on the outside of the mixing shaft 9. The torque output by the gear box 8 drives the mixing shaft 9 to rotate, thereby driving the mixing blade 10 to rotate, so that the mixing blade 10 fully mixes the material in the mixing housing 1. A discharge port 11 is provided at the bottom end of the mixing housing 1. After the mixing is completed, the material is discharged from the discharge port 11 at the bottom for filling and other operations.

[0025] According to the instruction manual Figure 1-3 It can be seen that a reflux port 12 is provided on one side of the above-mentioned discharge port 11, a reflux pipe 13 is connected to the reflux port 12, a circulation pump 14 is connected to one side of the reflux pipe 13, a mixing pipe 15 is connected to one side of the circulation pump 14, and the mixing pipe 15 is connected to one side of the mixing housing 1;

[0026] During the specific implementation process, the reflux port 12 is connected to the reflux pipe 13, and the circulating pump 14 is used to extract the mixed liquid from the bottom of the mixer housing 1 through the reflux pipe 13, and then the mixed liquid is passed into the upper layer of the mixer housing 1 through the mixing pipe 15, and then the refluxed material is returned to the mixed liquid at a high speed to realize the circulation exchange of the upper and lower materials, facilitate the full mixing of the materials, avoid the sedimentation of suspended matter, and at the same time, through the high-speed impact of the liquid flow, increase the shear force of the mixing and improve the mixing effect.

[0027] As a preferred solution, further, the gear box 8 is separately connected to the rotating shaft seat 6 of the top cover 2 through a flange, and the gear box 8 is also separately connected to the rotating motor 7 through a flange, which is convenient for disassembly and maintenance.

[0028] As a preferred solution, further, a coupling is connected to the output end of the gear box 8, the end of the mixing shaft 9 is connected to the coupling, and the coupling and the mixing shaft 9 are separately connected by bolts, which facilitates the separation and maintenance of the gear box 8 and the mixing shaft 9.

[0029] As a preferred solution, further, a rotating shaft sleeve is provided in the mixer housing 1 and sleeved on the mixing shaft 9 , and the rotating shaft sleeve plays a stabilizing role on the mixing shaft 9 .

[0030] As a preferred solution, further, a discharge control valve 16 is provided on the discharge port 11 for controlling the discharge of the liquid material.

[0031] As a preferred solution, further, a butt joint pipe 17 is extended from one radial side of the mixer housing 1, and the butt joint pipe 17 is connected to the end of the mixing pipe, so that the mixing pipe can be removed for maintenance.

[0032] From the above, it can be seen that the efficient batching machine for producing liquid fertilizer adopts a mixing machine shell 1 as the main body of the equipment. In addition, a mixing blade 10 is provided on the central axis of the mixing machine shell 1, and the mixing blade 10 is used to mix and stir the material. At the same time, a circulation pump 14 for extracting materials is provided at the bottom of the mixing machine shell 1.
