Description

Technical Field

[0001] This application relates to the technical field of fertilizer processing equipment, and particularly relates to a premixer. Background Art

[0002] At present, with the development of the aquaculture industry, the demand for fertilizers is increasing. Fertilizers contain a variety of raw materials, and they need to be fully and evenly mixed to produce qualified fertilizer products. Therefore, the mixing blender is an essential equipment for the fertilizer industry.

[0003] Currently, the commonly used mixing blender equipment basically uses a single agitator to complete all mixing work. Since the various materials are unevenly distributed during feeding, it takes a long time to stir them evenly, resulting in low mixing efficiency. Moreover, after mixing one batch, it is necessary to stop the machine and add different raw materials in sequence, which affects the production efficiency. Utility Model Content

[0004] In order to improve the mixing efficiency and production efficiency of chemical fertilizer raw materials, this application provides a premixer.

[0005] The premixer provided by this application adopts the following technical solutions:

[0006] A premixer includes an agitator, and also includes a pre-mixing tank arranged above the agitator and a driving component fixedly installed on the top of the agitator and driving the pre-mixing tank to vibrate. A telescopic pipe is connected between the feeding port at the bottom of the pre-mixing tank and the feeding port at the top of the agitator.

[0007] By adopting the above technical solutions, this application sets a vibratable pre-mixing tank above the agitator, enabling the pre-mixing of chemical fertilizer raw materials in the pre-mixing tank, improving the mixing efficiency of chemical fertilizer raw materials. Moreover, while the next batch of chemical fertilizer raw materials is being pre-mixed, the agitator is simultaneously stirring the chemical fertilizer raw materials in the previous batch, making the production more continuous. In addition, the pre-mixing tank can cache chemical fertilizer raw materials, eliminating the need to feed them into the agitator sequentially, shortening the feeding time, and improving the production efficiency.

[0008] Optionally, the driving component is a hydraulic cylinder component, and two groups of the driving components are arranged, respectively on both sides of the telescopic pipe.

[0009] By adopting the above technical solutions, the two groups of hydraulic cylinder components can better support the pre-mixing tank and the chemical fertilizer raw materials in the tank, thus facilitating the continuity of production.

[0010] Optionally, a plug cover is arranged above the feeding port in the pre-mixing tank, and a second driving component for controlling the telescopic movement of the plug cover to open or close the feeding port is installed on the pre-mixing tank.

[0011] Optionally, the second driving component is a hydraulic cylinder component.

[0012] By adopting the above technical solution, the hydraulic cylinder assembly can automatically control the opening or closing of the plug cover, thereby automatically controlling the feeding and saving labor.

[0013] Optionally, two sets of stirring devices are installed on the stirrer. The stirring device includes a motor fixedly installed on the top of the stirrer and a stirring rod fixedly connected to the output shaft of the motor. The stirring rod includes a main rod and a plurality of branch rods fixedly connected to the main rod.

[0014] By adopting the above technical solution, the application improves the stirring efficiency by arranging multiple sets of stirring devices.

[0015] Optionally, the feed inlet of the stirrer is located at the center of the top end of the stirrer, and the stirring devices are respectively arranged on both sides of the feed inlet of the stirrer.

[0016] Optionally, a deflector plate fixedly connected to the top end of the stirrer is provided at the feed inlet of the stirrer. There are a pair of deflector plates, which are respectively oriented towards different stirring rods.

[0017] By adopting the above technical solution, the deflector plate can deflect the fertilizer raw materials in the premixing tank towards the stirring rods, so as to stir the fertilizer raw materials more accurately and further improve the stirring efficiency.

[0018] Optionally, it further includes a first conveyor belt assembly for automatically feeding the premixing tank and a second conveyor belt assembly for transporting materials arranged below the stirrer.

[0019] By adopting the above technical solution, the first conveyor belt assembly and the second conveyor belt assembly can save labor and further improve the production efficiency.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The present application sets a vibratable premixing tank above the stirrer, so that the fertilizer raw materials in the premixing tank are premixed, improving the mixing efficiency of the fertilizer raw materials. And while the next batch of fertilizer raw materials is being premixed, the stirrer is simultaneously stirring the fertilizer raw materials in the previous batch, making the production more continuous. In addition, the premixing tank can cache the fertilizer raw materials, eliminating the need to feed them into the stirrer one by one, shortening the feeding time and improving the production efficiency;

Detailed implementation manners

[0026] The following further describes the present application in detail Figure 1-2 in conjunction with the appended

[0027] Embodiments of the present application disclose a premixer.

[0028] As Figure 1 and Figure 2 shown, a premixer includes a stirrer 1, a premixing tank 2 provided above the stirrer 1, and a first driving assembly 3 fixedly installed on the top of the stirrer 1 and capable of driving the premixing tank 2 to vibrate. The first driving assembly 3 is a hydraulic cylinder assembly, and two groups of hydraulic cylinder assemblies are provided. A telescopic pipe 21 is connected between the material discharge port at the bottom of the premixing tank 2 and the material inlet at the top of the stirrer 1. The telescopic pipe 21 can expand and contract with the vibration of the premixing tank 2. The material inlet of the stirrer 1 is located at the center of the top end of the stirrer 1, and the hydraulic cylinder assemblies are provided on both sides of the telescopic pipe 21.

[0029] In the present application, a premixing tank 2 that can vibrate up and down is provided above the stirrer 1, so that the chemical fertilizer raw materials in the premixing tank 2 are premixed, improving the mixing efficiency of the chemical fertilizer raw materials. While the stirrer 1 stirs the chemical fertilizer raw materials in the previous batch, the premixing tank 2 premixes the chemical fertilizer raw materials in the next batch, making the production more continuous. In addition, the premixing tank 2 can cache the chemical fertilizer raw materials, without feeding them into the stirrer 1 one by one, shortening the feeding time and improving the production efficiency.

[0030] As Figure 1 shown, a premixer further includes a first conveyor belt assembly 4 for automatically feeding the premixing tank 2 and a second conveyor belt assembly 5 for transporting materials provided below the stirrer 1.

[0031] The first conveyor belt assembly 4 and the second conveyor belt assembly 5 can save labor and further improve the production efficiency.

[0032] As Figure 1 and Figure 2As shown in the figure, a plug cover 22 is provided above the discharge port of the premixing tank 2. A second drive assembly 23 for controlling the expansion and contraction of the plug cover 22 to open or close the discharge port is fixedly installed on the premixing tank 2. The second drive assembly 23 is a hydraulic cylinder assembly. The hydraulic cylinder is installed on the outer wall of the premixing tank 2, and the output shaft of the hydraulic cylinder is fixedly connected to the plug cover 22.

[0033] The hydraulic cylinder assembly can automatically control the opening or closing of the plug cover 22, thereby automatically controlling the feeding and saving labor.

[0034] As Figure 2 shown in the figure, two sets of stirring devices 6 are installed on the stirrer 1. The stirring devices 6 are respectively arranged on both sides of the feed port of the stirrer 1. The stirring device 6 includes a motor 61 fixedly installed on the top of the stirrer 1 and a stirring rod 62 fixedly connected to the output shaft of the motor 61. The stirring rod 62 includes a main rod 621 and a plurality of support rods 622 fixedly connected to the main rod.

[0035] In this application, two sets of stirring devices 6 are provided and a plurality of support rods 622 are arranged on the main rod 621, further improving the stirring efficiency.

[0036] A deflector plate 7 fixedly connected to the top end of the stirrer 1 is provided at the feed port of the stirrer 1. There are a pair of deflector plates 7 with opposite flow guiding directions, respectively facing different stirring rods 62, so that the falling fertilizer raw materials are closer to the stirring rods 62, increasing the contact opportunity between the fertilizer raw materials and the stirring rods 62.

[0037] The deflector plate 7 can deflect the fertilizer raw materials in the premixing tank 2 towards the stirring rods 62, thereby being able to stir the fertilizer raw materials more precisely and further improving the stirring efficiency.

[0038] The implementation principle of an example of a premixer in this application is as follows: The fertilizer raw materials are conveyed to the premixing tank 2 through the first conveyor belt assembly 4. The hydraulic cylinder assembly controls the up and down vibration of the premixing tank 2. After premixing, the hydraulic cylinder assembly controls the expansion and contraction of the plug cover 22, exposing the discharge port of the premixing tank 2. The premixed fertilizer raw materials fall into the stirrer 1 through the telescopic pipe 21. The motor 61 is started, and the stirring rod 62 stirs the fertilizer raw materials. The stirred fertilizer falls onto the second conveyor belt assembly 5 for the next step.

[0039] The examples of this specific implementation manner are all preferred examples of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
