Description
The utility model relates to a kind of powder classification device that is used for industry classifying fine particles such as chemical industry, medicine, agricultural chemicals, dyestuff, mineral products and light industry, particularly a kind of ultrafine powder grading plant.
In the prior art, powder classification device is made up of grader, high pressure positive blower and powder body trap.Its grader generally is to adopt the eddy flow centrifugal separation method, and its structure is a cylinder tangential admission, makes material realize isolating coarse-grained material with the rotation generation centrifugal force of air-flow, thereby collects fine.This powder classification device generally can only separate the following powder of 325 orders, and along with the variation of wind speed, air quantity can influence the powder granularity that institute separates acquisition, is difficult to guarantee the uniformity of partition size, and effectiveness of classification is not high.
The purpose of this utility model is to provide a kind of grading plant that can separate ultrafine powder, the epigranular of classification, effectiveness of classification height.
For achieving the above object, the utility model adopts following technical proposals: the same grader, high pressure positive blower and the powder body trap that is communicated with successively that include with prior art of this ultrafine powder grading plant.Be characterized in: in grader, be equipped with by motor-driven rotary blade.Like this, because the rotation of rotary blade makes powder have bigger rotary centrifugal force, and is applicable to the classification of ultrafine powder.In that accurately the control motor speed is constant, just can obtain the classification uniform grain sizes, the effectiveness of classification height; Set up different motor speeds, just can obtain varigrained classification, grading range is big.
It is vertical cylindrical body that grader of the present utility model can be designed as housing, and center, its underpart connects a feed hose that is used to be communicated with grinding mill.And vertically commercially available wind stopping device is equipped with in the lower end that connects back hopper, cylindrical body bottom, is dished out by centrifugal force and the coarse granule that sinks is collected in the back hopper lower end, is sent back to grinding mill to mill again behind wind stopping device, and wind stopping device then stops air-flow to flow out.Vertically the top inner chamber of cylindrical body is installed rotary blade, makes material produce centrifugal force; Vertically there is discharging opening at the center of the conical lid on cylindrical body top, and discharging opening is communicated with the import of a swirler, and the outlet of swirler connects feed pipe.Motor is installed on the top of grader, and its output shaft connects the rotating shaft of rotary blade.This motor can adopt commercially available stepless speed-regulating motor.Above-mentioned rotary blade can be designed to the upper and lower side of a rotating shaft rotating disk is installed respectively, the sheet fan blade is installed between the outer rim of two rotating disks is formed back taper shape impeller, air vent is arranged on the top rotary table, then large granular materials produces centrifugal action and is dished out under the impeller rotation drives, sink then, satisfactory fine powder then by the wind intake impeller after the air vent of top rotary table enters swirler.The outer rim of the top rotary table of described rotary blade is processed into laminar, is in to be installed in up and down between the damping fin of vertical cylindrical body inboard, constitutes the sealing device of top rotary table outer rim.Can prevent the coarse-grained material swirler that bleeds like this.
It is the setting cylindrical shell that aggregate bin is equipped with in the bottom that powder body trap of the present utility model can be designed to housing, interior dress filter bag.Erect cylindrical shell top the tangential admission mouth is installed, be communicated with grader by feed pipe.Commercially available wind stopping device is equipped with in the lower end of aggregate bin.The powder body that classification is good is discharged by wind stopping device, and air-flow can not flow out from wind stopping device.The inner chamber of filter bag is communicated with the import of high pressure positive blower by induced duct.Because this powder body trap is designed to tangential admission, inlet air flow plays the shake effect to filter bag, prevents that filter bag from stopping up.
Grader of the present utility model, high pressure positive blower and powder body trap can be installed on the frame, constitute an integral body.Then the user uses installation extremely convenient.
The utility model compared with prior art has following conspicuous advantage: be applicable to the classification of ultrafine powder, can separate 500～2000 purpose powders, partition size is even, the effectiveness of classification height, and grading range is wide; And the utility model is assembled into an integral body, and it is extremely convenient to install and use.
