Abstract
A kind of coal mud water slurry productive technology, technology is simple, energy consumption is low, comprise the steps: feed coal through conveyor delivery to Slurry homogenizing bin, in Slurry homogenizing bin, inject suitable quantity of water according to feed coal concentration, and add dispersant and stir; By closed conduit the slurry in the Slurry homogenizing bin is delivered to ball mill with underflow pump and carries out the ore grinding processing; The discharging of above-mentioned steps gained grinding machine filter removed by separator be delivered to agitator behind the impurity and carry out brute force and stir, and an amount of stabilizing agent of adding is controlled viscosity of coal-water slurry in agitator; Above-mentioned steps gained slurry is delivered to strengthens pump and carry out being delivered to slurry can after the brute force shearing and carry out slaking, water-coal-slurry gets product.The present invention is used for the production water-coal-slurry, directly the slurry in the Slurry homogenizing bin is delivered to ball mill by underflow pump, has omitted existing repeatedly agitating procedure, has simplified production technology, has reduced energy consumption.
Description
Technical field
The present invention relates to a kind of slurries production technology, relate in particular to a kind of with the technology of coal slime as raw material production water-coal-slurry.
Background technology
At present, the feed coal that uses in the slurries production technology is floatation clean coal, needs repeatedly to stir the technological requirement that just can reach next procedure before feed coal enters the ball mill ore grinding, the complex production process of this water-coal-slurry, and energy input is big.
Summary of the invention
The purpose of this invention is to provide the coal mud water slurry productive technology that a kind of technology is simple, energy consumption is low.
For achieving the above object, the technical solution used in the present invention is:
A kind of coal mud water slurry productive technology, its characteristics are: comprise the steps:
A, feed coal to Slurry homogenizing bin, to Slurry homogenizing bin in inject suitable quantity of water according to feed coal concentration through conveyor delivery, and the adding dispersant stirs;
B, by closed conduit the slurry in the Slurry homogenizing bin is delivered to ball mill with underflow pump and carries out ore grinding and handle;
C, the discharging of above-mentioned steps b gained grinding machine filter removed by separator be delivered to agitator behind the impurity and carry out brute force and stir, and an amount of stabilizing agent of adding is controlled viscosity of coal-water slurry in agitator;
D, above-mentioned steps c gained slurry is delivered to strengthens pump and carry out being delivered to slurry can after the brute force shearing and carry out slaking, water-coal-slurry gets product.
The present invention directly is delivered to ball mill with the slurry in the Slurry homogenizing bin by underflow pump, has omitted existing repeatedly agitating procedure, has simplified production technology, has reduced energy consumption.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further described:
A kind of coal mud water slurry productive technology as shown in Figure 1, comprises the steps:
Feed coal is delivered to Slurry homogenizing bin through drag conveyor, injects suitable quantity of water satisfying the slurry concentration requirement in Slurry homogenizing bin according to feed coal concentration, and adds dispersant and stir; By closed conduit the slurry in the Slurry homogenizing bin is delivered to ball mill with underflow pump then and carries out the ore grinding processing, in this operating process, can adjust the granularity of slurry by the load of control underflow pump; The grinding machine discharging of above-mentioned steps gained is delivered to separator from the collection stock tank, carry out the brute force stirring by being delivered to agitator behind the separator filtration removal large granular impurity, and an amount of stabilizing agent of adding is controlled viscosity of coal-water slurry in agitator; At last, above-mentioned steps gained slurry is delivered to the reinforcement pump with screw pump, carries out brute force and shear, then be delivered to slurry can and carry out slaking, make it become the finished product water-coal-slurry of stable performance.
Use the present invention to produce one ton of water-coal-slurry and only need power consumption 13.5 degree, improve a lot, saved the energy, reduced production cost than traditional handicraft (ton slurry power consumption is 30 degree).
In addition, the duff that the present invention is not only applicable to use coal preparation plant is more suitable for coming production water-coal-slurry less than the coal slime of 0.5mm as feed coal in particle as feed coal, has reduced the requirement to feed coal, and the scope of application is wider.
Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
