Embodiment 1

[0037] Such as Figures 1 to 4 As shown, a new slurry stirring device includes a stirring tank 1, a slurry discharge pipe 2 and a slurry discharge valve 3, the slurry discharge pipe 2 is connected through the bottom of the stirring tank 1, an air compressor 4, and a first electric control valve 5 , the second electronically controlled valve 6, the PLC controller 7, the first group of high-pressure air pipes 8, the second group of high-pressure air pipes 9, and the jet head-10 connected to one end of the first group of high-pressure air pipes 8 and the second group of high-pressure air pipes 9;

[0038] The first group of high-pressure air pipes 8 and the second group of high-pressure air pipes 9 are connected to the air compressor 4 through the first electric control valve 5 and the second electric control valve 6 respectively;

[0039] The PLC controller 7 is connected to the first electric control valve 5 and the second electric control valve 6, and alternately controls the ...

Embodiment 2

[0047] Such as Figure 5 As shown, on the basis of Example 1, the stirring effect is further optimized, and several side wall high-pressure air pipes 13 are connected to the front wall and the rear wall of the stirring tank 1, and the side wall high-pressure air pipes connected to the front wall of the stirring tank 1 13 The air inlet end is connected with the first electric control valve 5, and the side wall high-pressure gas pipe 13 which is connected to the rear wall of the stirring tank 1 is connected with the second electric control valve 6.

[0048] Further, the side wall high-pressure air pipe 13 is connected to the end of the stirring tank 1 connected with the second nozzle 11, and the direction of the second nozzle 11 is inclined upward with respect to the plane of the side wall of the stirring tank 1.

[0049] The above-mentioned arrangement of several sidewall high-pressure air pipes on the sidewall of the stirring tank further accelerates the flow velocity of the s...

Embodiment 3

[0051] Such as Figures 1 to 5 As shown, on the basis of Embodiments 1 and 2, further, the first nozzle 10 and the second nozzle 11 are provided with a check valve 12 to prevent the slurry from flowing back into the high-pressure air pipe.

[0052] During normal operation, under the action of high-pressure gas, the slurry cannot enter the high-pressure air pipe, but when the stirring is stopped, the slurry will flow into the high-pressure air pipe, which will easily cause blockage after a long time, so setting a check valve can effectively prevent The slurry flows back into the high-pressure gas pipe.

[0053] Further, the inclination angle between the air jet head 10 and the bottom plane of the stirring tank 1 is 20°-70°, and the inclination angle between the air jet head two 11 and the side wall plane of the stirring tank 1 is 20°-70°.

[0054] In actual use, the above-mentioned inclination angle will be adjusted and determined according to the size of the stirring tank, th...

Abstract

The invention discloses a novel slurry stirring device. The device comprises a stirring tank, a slurry discharging tube, a slurry discharging valve, the slurry discharging valve is connected to the bottom of the stirring tank in a through manner, the device further comprises an air compressor, a first electric control valve, a second electric control valve, a PLC, a first set of high-pressure airtubes, a second set of high-pressure air tubes and first air spraying heads connected to one ends of the first high-pressure air tubes and the second high-pressure air tubes. The plurality of high-pressure air tubes are communicated with the bottom and the sidewall of the stirring tank, the air spraying directions of the air spraying head are designed to be in an inclined state, the PLC is adoptedto carry out grouping alternate control on the high-pressure air tubes, and the air spraying heads spray high-pressure air in different directions under the action of the air compressor in a time-sharing mode to stir a slurry, so the slurry is stirred sufficiently and evenly, and settlement of the slurry is avoided; and no hardware devices for stirring the slurry are arranged in the stirring tank, and the problem of maintenance of the stirring hardware devices is solved, so the expenditure investment is saved, and the use efficiency of the stirring tank is also improved.

Description

technical field [0001] The invention relates to the field of slurry stirring, in particular to a novel slurry stirring device. Background technique [0002] In many process industries, solid-liquid separation is an essential unit operation process, such as metallurgy, mineral processing, chemical industry, light industry, food, pharmaceuticals, environmental protection, biological products, etc. Some manufacturing industries, even if they do not belong to the process industry, require solid-liquid separation because their products are solid and the production process needs to be carried out in liquid. In these processes, solid-liquid separation is one of the key operations, and its technical level and quality directly affect the possibility of process realization, the advancement and reliability of the process, product quality, energy consumption, and environmental protection. and other economic and social benefits. [0003] In the process of solid-liquid separation, diffe...
