Technical Field

[0001] The utility model relates to the field of feed production, in particular to a device for mixing raw materials with accurate proportions. Background Art

[0002] In current industrial production, the accurate proportioning of various raw materials is a crucial factor affecting production quality. For example, in the production of powdered calcium and zinc products, certain special functional requirements require that several liquid raw materials be mixed to form a batch, which is then added to the powder for further mixing. However, this production process often results in inaccurate metering and proportioning, leading to low mixing efficiency. Utility Model Content

The first rotating shaft extends laterally, and a plurality of stirring blades are evenly distributed along the circumference of the outer wall of the first rotating shaft. In this optimization solution, the first motor drives the first rotating shaft, thereby driving the stirring blades to stir the raw materials, thereby evenly mixing the raw materials.

[0007] As an optimization, the stirring blades are in a wave-shaped structure. This optimization solution can speed up the mixing of the liquid.

The fourth electrically controlled valve is also controlled by the PLC controller, further improving ease of use and increasing production efficiency.

[0010] As an optimization, the second stirring mechanism includes a second rotating shaft rotatably connected to the tank body and a second motor driving the second rotating shaft. The second rotating shaft extends vertically, and a plurality of stirring rods are evenly distributed along the circumference of the outer wall of the second rotating shaft. In this optimization solution, the second motor drives the second rotating shaft, thereby driving the stirring rods to evenly mix the powder and ingredients.

[0012] As an optimization, an electric heater is provided in the tank. This optimization solution increases the mixing temperature of the powder and liquid ingredients, improves the mixing efficiency, and makes the mixing more uniform.

[0013] The beneficial effects of this utility model are as follows: the liquid raw materials in the first and second raw material chambers enter the proportioning chamber through the first liquid discharge port for stirring and mixing. The amount of liquid raw material added is monitored by a first electronic flowmeter, and the opening and closing of the first electrically controlled valve is controlled by a PLC controller, thereby achieving quantitative addition of the liquid raw materials and greatly improving the accuracy of the raw material proportioning. The mixer uses an electric heater to increase the mixing temperature of the powder and liquid ingredients, improving mixing efficiency and achieving a more uniform mixing.

The first and second raw material chambers 11 and 12 are arranged on the left and right sides, and each of the first and second raw material chambers 11 and 12 is fixedly equipped with a liquid level gauge 26.

[0019] First liquid inlets 6 are provided on the side walls of the first and second raw material chambers 11, 12. First liquid discharge ports 3, located within the proportioning chamber 2, are provided at the bottoms of both the first and second raw material chambers 11, 12. Both first liquid discharge ports 3 are equipped with first electrically controlled valves 5 and first electronic flowmeters 4. The liquid raw materials in the first and second raw material chambers flow through the first liquid discharge ports into the proportioning chamber for mixing.

[0020] The mixing chamber 2 is provided with a first stirring mechanism, which includes a first rotating shaft 8 rotatably connected to the mixing chamber 2 and a first motor 7 that drives the first rotating shaft. The first rotating shaft 8 extends laterally, and a plurality of stirring blades 9 are uniformly distributed along the circumference of the outer wall of the first rotating shaft 8. The stirring blades 9 have a wavy structure. In this embodiment, both ends of the first rotating shaft 8 are rotatably connected to the two side walls of the mixing chamber 2. The first motor 7 is fixed to the side wall of the mixing chamber 2, and the output end of the first motor 7 is fixedly connected to one end of the first rotating shaft 8.

[0021] A second liquid discharge port 13 is provided at the bottom of the proportioning bin 2 , and a third electrically controlled valve 14 is provided on the second liquid discharge port 13 .

[0022] The mixer is provided with a second liquid inlet 16, and the mixer includes a tank body 15. The second liquid inlet 16 is located on the side wall of the tank body 15. A second electrically controlled valve 18 and a second electronic flow meter 17 are provided on the second liquid inlet 16. The second liquid inlet 16 and the second liquid outlet 13 are connected through a delivery pipe 10.

[0023] The tank body 15 is provided with a feed port 23 and a third liquid inlet 19 at the top, a discharge port 24 at the bottom, and a fourth electrically controlled valve 25 at the discharge port 24 .

[0024] A second stirring mechanism is disposed within the tank body 15. The second stirring mechanism includes a second rotating shaft 21 rotatably connected to the tank body 15 and a second motor 20 that drives the second rotating shaft. The second rotating shaft 21 extends vertically, and a plurality of stirring rods 22 are evenly distributed along the circumference of the outer wall of the second rotating shaft 21.

The PLC controller controls the opening of the two first electronically controlled valves 5 to allow the liquid raw materials to enter the mixing chamber 2 for mixing. The first electronic flowmeter 4 monitors the liquid raw material flow rate. When the set value is reached, the PLC controller controls the closing of the two first electronically controlled valves 5. At the same time, the first motor 7 is controlled to drive the first rotating shaft 8 to rotate, causing the first stirring mechanism to stir and mix the two liquid raw materials to form the raw materials.

[0028] The PLC controller then controls the opening of the second and third electrically controlled valves 18 and 14, allowing the mixed ingredients to be fed into the tank 15. The second electronic flowmeter 17 monitors the ingredient flow rate. When the set value is reached, the PLC controller controls the closing of the second and third electrically controlled valves 18 and 14.

When the ingredients are added, the PLC controller controls the second motor 20 to drive the second rotating shaft 21 to rotate, causing the second stirring mechanism to evenly mix the ingredients and powdered raw materials. The PLC controller then controls the opening of the fourth electrically controlled valve 25 to discharge the mixed materials.
