Water coal slurry high shear intensified pump
Technical field
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 technique
Water coal slurry, by the coal of about 65%, water and a small amount of chemical additives of 34% are made, it is a kind of fuel slurry, can pumping as oil, atomization, storage and smooth combustion, its calorific value is equivalent to the half of fuel oil, and fuel oil can be replaced to be used for boiler, power station, industrial furnace and kiln, for replacing coal directly to use or replacing fuel oil, having that combustion benefits is high, load adjustment is convenient, reduce environmental pollution, improving working conditions and the advantage such as saving coal or coal replacing oil.
After traditional coal-water-slurry completes, its viscosity is very high, and spraying effect is bad, combustion efficiency is low, because viscosity is very high, so mobility is very poor, easy generation pipeline blockage and spray gun spray nozzle blocking, improve CWS Reological Properties energy and stability, reduce Cws Viscosity.
Summary of the invention
The present invention is high for solving current Cws Viscosity, the problem of poor fluidity, for herein is provided a kind of water coal slurry high shear intensified pump, comprise base, described base is fixedly installed drive motor, described drive motor is connected with high-shear device, described high-shear device comprises support, turbine casing and end cap, described support one end is provided with rotor assembly, described rotor assembly comprises transmission shaft, one end of described transmission shaft is provided with propelling cutter, described propelling cutter is fixed on transmission shaft by adjusting head, described end cap is connected with stator module, described stator module comprises external toothing, middle gear ring and ring gear.
As preferably, described turbine box house is provided with slurry outlet groove and water-flowing trough, and the shape of described turbine casing is swirl shape, and pulp aisle spare is progressively zoomed in, and produces pressure.
As preferably, described propelling cutter comprises body and some helical tooths, and described propelling cutter is coordinated by keyway and is connected with transmission shaft.
The invention has the beneficial effects as follows: the present invention utilizes the High Rotation Speed of rotor assembly, the viscosity of water coal slurry is reduced, increase mobile performance, pipeline or spray nozzle clogging are less likely to occur, extend the working life of pipeline and nozzle, and improve the density of water coal slurry, increase combustion efficiency, add rheological characteristic and the stability of water coal slurry, be more conducive to preserve.

Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
A kind of water coal slurry high shear intensified pump as shown in Figure 1, comprise base 1, described base 1 is fixedly installed drive motor 2, described drive motor 2 is connected with high-shear device 3, as shown in Figure 2, described high-shear device 3 comprises 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 comprises transmission shaft 4.1, one end of described transmission shaft 4.1 is provided with and advances cutter 4.2, described propelling cutter 4.2 is fixed on transmission shaft 4.1 by adjusting head 4.3, as shown in Figure 4, described end cap 3.3 is connected with stator module 5, described stator module 5 comprises external toothing 5.1, middle gear ring 5.2 and ring gear 5.3.
As shown in Figure 6, described turbine casing 3.2 inside is provided with slurry outlet groove 3.21 and water-flowing trough 3.22, and the shape of described turbine casing 3.2 is swirl shape, and pulp aisle spare is progressively zoomed in, and produces pressure.
As shown in Figure 5, described propelling cutter 4.2 comprises body 4.21 and some helical tooths 4.22, and described propelling cutter 4.2 is coordinated by keyway and is connected with transmission shaft 4.1.
Described stator module 5 and the respective assembly parts of rotor assembly 4 are fixed by bolt and locating stud.
In use, water coal slurry enters from end cap 3.3, between stator module 5 and rotor assembly 4, finally flow out from the slurry outlet groove 3.21 of turbine casing 3.2, through the High Rotation Speed of rotor assembly 4, increase water coal slurry density, reduce viscosity, increase mobility, can heat be produced in rotary course, water-flowing trough 3.22 have water intake and water outlet, cold water bottom in and top out, entered water-flowing trough 3.22 and take away heat, adjusting head 4.3 can regulate the gap of stator module 5 and rotor assembly 4, reaches the effect regulating the different viscosity of water coal slurry finished product.
Make high viscosity metabolic water coal slurry be down to below 1200mpa.s, ensure spray burning effect, improve whitewashing Security and improve the spray tip life-span.Improve the yield strength of water coal slurry, yield strength is higher, water coal slurry stability better, ensures that the slurry for subsequent use in circulating tank stablized number of days more than 60 days.
The present invention utilizes the High Rotation Speed of rotor assembly, the viscosity of water coal slurry is reduced, increase mobile performance, pipeline or spray nozzle clogging are less likely to occur, extend the working life of pipeline and nozzle, and improve the density of water coal slurry, increase combustion efficiency, add rheological characteristic and the stability of water coal slurry, be more conducive to preserve.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
