The present invention relates to water-coal-slurry slurring apparatus field, especially relate to a kind of water-coal-slurry high shear intensified pump.
Background technology
Water-coal-slurry, by 65% about coal, 34% water and a small amount of chemical addition agent are made, and are a kind of fuel slurries, permissible Pump, be atomized, store and stablize burning as oil, its calorific value is equivalent to the half of fuel oil, fuel oil can be replaced to be used for pot Stove, power station, industrial furnace and kiln, for replacing coal directly to use or replacing fuel oil, have combustion benefits height, load adjustment just Profit, reduce environmental pollution, improve working conditions and saving coal or the advantages of with coal for replacing oil.
After traditional coal-water-slurry completes, its viscosity is very high, and spraying effect is bad, and efficiency of combustion is low, because viscosity is very high, So mobility is very poor, it is susceptible to pipeline blockage and spray gun spray nozzle blocking, improves CWS Reological Properties energy and stability, Reduce Cws Viscosity.
Content of the invention
The present invention is to solve current Cws Viscosity height, the problem of poor fluidity, provides a kind of water-coal-slurry height for this and cuts Cut strengthening pump, including base, described base is fixedly installed driving motor, described driving motor is connected with high shear dress Put, described high-shear device includes support, turbine casing and end cap, described support one end is provided with rotor assembly, described rotor Assembly includes power transmission shaft, and one end of described power transmission shaft is provided with propulsion knife, and described propulsion knife is fixed on power transmission shaft by adjusting head On, described end cap is connected with stator module, described stator module includes external toothing, middle gear ring and ring gear;
Described turbine box house is provided with slurry outlet groove and water-flowing trough, described turbine casing be shaped as swirl shape, make Pulp aisle spare progressively zooms in, and produces pressure;
Described propulsion knife includes body and some helical tooths, and described propulsion knife is connected with power transmission shaft by keyway cooperation.
The invention has the beneficial effects as follows:The present invention utilizes the high-speed rotation of rotor assembly, so that the viscosity of water-coal-slurry is reduced, and increases Plus mobile performance, it is not easy to there is pipeline or spray nozzle clogging, extends the service life of pipeline and nozzle, and improves water coal The density of slurry, increases efficiency of combustion, increased rheological characteristic and the stability of water-coal-slurry, more conducively preserve.

Specific embodiment
All features disclosed in this specification, or disclosed all methods or during step, except mutually exclusive Feature and/or step beyond, all can combine by any way.
This specification(Including any accessory claim, summary and accompanying drawing)Disclosed in any feature, except non-specifically is chatted State, all can be replaced by other alternative features equivalent or that there is similar purpose.I.e., unless specifically stated otherwise, each feature It is a series of equivalent or one of similar characteristics example.
A kind of water-coal-slurry high shear intensified pump as shown in Figure 1, including base 1, described base 1 is fixedly installed transmission Motor 2, described driving motor 2 is connected with high-shear device 3, as shown in Fig. 2 described high-shear device 3 include support 3.1, Turbine casing 3.2 and end cap 3.3, described support 3.1 one end is provided with rotor assembly 4, as shown in figure 3, described rotor assembly 4 wraps Include power transmission shaft 4.1, one end of described power transmission shaft 4.1 is provided with propulsion knife 4.2, and it is fixing that described propulsion knife 4.2 passes through regulation 4.3 On power transmission shaft 4.1, as shown in figure 4, being connected with stator module 5 on described end cap 3.3, described stator module 5 includes external toothing 5.1st, middle gear ring 5.2 and ring gear 5.3;
As shown in fig. 6, described turbine casing 3.2 is internally provided with slurry outlet groove 3.21 and water-flowing trough 3.22, described turbine box Body 3.2 be shaped as swirl shape, so that pulp aisle spare is progressively zoomed in, produce pressure;
As shown in figure 5, described propulsion knife 4.2 includes body 4.21 and some helical tooths 4.22, described propulsion knife 4.2 passes through Keyway cooperation is connected with power transmission shaft 4.1.
