Abstract
The invention discloses a novel powder grading device. The novel powder grading device comprises a cyclone and a rack, wherein the cyclone and the rack are fixedly connected, and an air inlet is formed in the side wall of the cyclone; the novel powder grading device further comprises a single-layer grading tanks and double-layer grading tanks, each single-layer grading tank and the corresponding double-layer grading tank are fixedly connected to the outer side wall of the cyclone from inside to outside sequentially, and a first filter screen is arranged between each single-layer grading tank and the cyclone. The novel powder grading device has the benefits as follows: dust can be separated into different grades by the grading device, production requirements are met, and maximized production benefits are realized.
Description
Technical field
The present invention relates to and select powder equipment, be specifically related to a kind of novel stagewise powder selection device.
Background technology
Powder lot classifying apparatus is used for the production of portland cement, flour manufacture.The cardinal principle of most of grader is separated by the dust of variable grain by the effect of whirlwind generation centrifugal force.Oarse-grained dust receives larger centrifugal action and is thrown toward outermost.Fine grain dust will be collected in cyclone cylinder in sedimentation.But the thickness grade that this classification produces is also insufficient.Usually according to the restriction of working condition in reality production process, need the powder of different fineness.
The fineness degree of dust is needed to be divided into different grades.And existing technical scheme can not reach such requirement.
Summary of the invention
The invention provides a kind of Novel powder grading plant, dust can be divided into different grades by this grading plant, meets the needs of production, and production interests is obtained and maximizes.
The invention provides following technical proposals: a kind of Novel powder grading plant, comprises cyclone cylinder, frame.Described cyclone cylinder is fixedly connected with described frame, and the sidewall of described cyclone cylinder is provided with air inlet.Described Novel powder grading plant also comprises one deck classification case, two layers of classification case, described one deck classification case, two layers of classification case are fixedly connected sequentially in described cyclone cylinder lateral wall from inside to outside, are provided with the first filter screen between described one deck classification case and described cyclone cylinder.Be provided with the second filter screen between described one deck classification case and described two layers of classification case, be communicated with by described first filter screen, the second filter screen between described cyclone cylinder, one deck classification case, two layers of classification case.The top of described cyclone cylinder is connected with the gas outlet with the inner space of described cyclone cylinder.
Further, the diameter of the mesh of described first filter screen, the second filter screen is 600 ~ 800 microns.
Further, described one deck classification case, two layers of classification case present annular array and are surrounded on around described cyclone cylinder, and the group number of described one deck classification case, two layers of classification case is 2 ~ 3 groups.
Further, the below of described cyclone cylinder, one deck classification case, two layers of classification case is provided with discharging opening described in discharging opening and is built-in with steel impeller.
Useful effect effect of the present invention: the high speed whirlwind that powder is flow to by described air inlet by the first filter screen of the present invention, the second filter screen.Carry out centrifugally screening layer by layer.Material after screening flows out from discharging opening.Dust can be divided into different grades by this grading plant of the present invention, meets the needs of production, and production interests is obtained and maximizes.
Accompanying drawing explanation
Fig. 1 is the front view of Novel powder grading plant of the present invention.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the invention will be further described.
In Fig. 1, Fig. 2: cyclone cylinder 1, frame 2, one deck classification case 3, two layers of classification case 4, first filter screen 5, second filter screen 6, discharging opening 7, steel impeller 8, gas outlet 9, air inlet 10, thin screen pack 11.
A kind of Novel powder grading plant, comprise cyclone cylinder 1, frame 2, described cyclone cylinder 1 is fixedly connected with described frame 2.The sidewall of described cyclone cylinder 1 is provided with air inlet 10.Described Novel powder grading plant also comprises one deck classification case 3, two layers of classification case 4, and described one deck classification case 3, two layers of classification case 4 are fixedly connected sequentially from inside to outside in described cyclone cylinder 1 lateral wall.The first filter screen 5 is provided with between described one deck classification case 3 and described cyclone cylinder 1.The second filter screen 6 is provided with between described one deck classification case 3 and described two layers of classification case 4.Be communicated with by described first filter screen 5, second filter screen 6 between described cyclone cylinder 1, one deck classification case 3, two layers of classification case 4.The top of described cyclone cylinder 1 is connected with the gas outlet 9 with the inner space of described cyclone cylinder 1.The described object setting out inflator 9 is to make, and the air-flow flowing to described cyclone cylinder 1 can flow out, and makes to form stable air-flow in described cyclone cylinder 1.
The diameter of the mesh of described first filter screen 5, second filter screen 6 is 600 ~ 800 microns.Change the coarse grained dust of size can pass through smoothly.Meet and use.When the dust being greater than 800 microns will be settled down to the bottom of described cyclone cylinder 1.The bottom of described cyclone cylinder 1 is provided with thin screen pack 11, and invalid coarse grained dust will have the filtering of thin screen pack 11.
Described one deck classification case 3, two layers of classification case 4 present annular array and are surrounded on around described cyclone cylinder 1, and the group number of described one deck classification case 3, two layers of classification case 4 is 2 ~ 3 groups.
The below of described cyclone cylinder 1, one deck classification case 3, two layers of classification case 4 is provided with discharging opening 7 described in discharging opening 7 and is built-in with steel impeller 8.
Oarse-grained dust receives larger centrifugal action and is thrown toward outermost.Relatively a little bit smaller dust is then separated and relative to described cyclone cylinder center.The thinnest dust will be collected in cyclone cylinder in sedimentation.
