Description
Technical field
The present invention relates to a kind of cement slurry homogenizer, particularly relate to a kind of cement raw-material homogenizing discharge system.
Background technology
In cement production process, the storage of raw material and homogenizing are the material guarantee that cement kiln runs the most continuously, in four key links of raw material preparation system, the homogenizing cycle of raw material homogenizing silo is shorter, homogenization is bigger, being again last the homogenizing link before raw material enter kiln, homo-effect is particularly important.In cement slurry preparation process, people are pursuing the cement slurry ideal with minimum power consumption acquisition homogenization coefficient all the time, thus obtain the biggest economic benefit.At present, existing raw material homogenizing silo bottom of the reservior homogenizing discharge system feeding mode is single, it is impossible to enough carries out mixing homogenizing to the raw material of zones of different and different component in warehouse-in during difference or storehouse body, is not easy to realize multi-mode and automatically controls.
Because above-mentioned defect, the design people, the most in addition research and innovation, to founding the cement slurry homogenizing discharge system of a kind of new structure so that it is have more the value in industry.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of when extracting difference in warehouse-in, storehouse body the raw material of zones of different or different component carry out mixing the cement raw-material homogenizing discharge system of homogenizing.
nullThe cement raw-material homogenizing discharge system of the present invention，Including pedestal and be fixedly installed on the storehouse body above pedestal，The end face of described pedestal is the back taper inclined-plane that portion tilts wherein，Decompression cone it is provided with at the middle part of the end face of pedestal，The bottom of described decompression cone is along the circumferential direction provided with at least two charging hole，On the end face of described pedestal, the position of corresponding each charging hole is equipped with passage，And at least a part of which has the length of a passage different from the length of other passage，The bottom of the described passage inner chamber with charging hole UNICOM and by charging hole with decompression cone communicates，First class rod it is provided with in described passage，On the end face of described pedestal, corresponding every passage is additionally provided with deflector chute，Described deflector chute is between the storehouse wall of the top of passage and storehouse body，The bottom of deflector chute extends to the top of passage，The second fluidized bar it is additionally provided with in described deflector chute；
At least two subregion supply endless tube it is additionally provided with in the body of described storehouse, the input of subregion supply endless tube is connected with outside gas source by electromagnetic valve respectively, and first class rod in described passage and the second fluidized bar in the corresponding deflector chute that connects to passage supply one of them subregion in endless tube by pipeline and at least two subregion respectively and supply endless tube UNICOM；
Described cement raw-material homogenizing discharge system also includes controlling device, and described control device can send a control signal to electromagnetic valve thus control the break-make between each subregion supply endless tube and gas source.
By such scheme, the present invention at least has the advantage that the cement raw-material homogenizing discharge system of the present invention, it is equipped with passage on the end face of its pedestal, and at least the length of a passage and the length of other passages are different, it is additionally provided with deflector chute between top and the storehouse wall of passage, first class rod it is provided with in passage, the second fluidized bar it is provided with in deflector chute, additionally include that at least two subregion supplies endless tube, subregion supply endless tube is connected with outside gas source by electromagnetic valve respectively, and the first class rod in passage and the second fluidized bar in the corresponding deflector chute that connects to passage are respectively by pipeline and one of them subregion supply endless tube UNICOM at least two subregion supply endless tube；nullAssume the passage having two kinds of length，Then the end face of pedestal is divided into outer zone and two regions of interior ring region by two kinds of different passages，Wherein the region between the top of longer passage and storehouse wall is outer zone，The region being positioned at the top of longer passage and the top of shorter passage is ring region，The cement slurry being positioned at outer zone enters into decompression cone along longer passage under the fluidization of first class rod and the second fluidized bar，The cement slurry being positioned at ring region enters into decompression cone along shorter passage under the fluidization of first class rod and the second fluidized bar，As long as being separately turned on first class corresponding with different ring region rod as required and the cement slurry in different ring region can being pumped the purpose to decompression cone by the second fluidized bar，Thus realize being divided into the cement slurry in the body of storehouse two different annular regions；In addition, control system is by sending a control signal to electromagnetic valve, thus control the break-make of each subregion supply endless tube, and each subregion supply endless tube respectively with the first class rod in respective regions and the second fluidized bar UNICOM, thus realize along the circumferential direction being divided into the cement slurry in the body of storehouse the purpose in several regions, assume there are four subregion supply endless tubes, then storehouse body can be divided into four right angle sector regions by these four subregion supply endless tubes, if the subregion supply endless tube opened in respective regions, the all cement slurries in corresponding right angle sector region or the cement slurry in part ring region can be made to pump to decompression cone.In sum, when the cement raw-material homogenizing discharge system of the present invention can extract difference, in warehouse-in, storehouse body, the raw material of zones of different or different component carry out mixing homogenizing.
