Description

A kind of disc type airslide disintegrating mill
Technical field:
The utility model relates to field of crushing equipment, is specifically related to a kind of disc type airslide disintegrating mill.
Background technology:
Airslide disintegrating mill is the visual plant carrying out superfine powder processing, and because airslide disintegrating mill needs compressed air as source of the gas, therefore production process power consumption is higher.Under the prerequisite ensureing product cut size, improving crush efficiency as far as possible, reduce specific energy consumption, is the direction of airslide disintegrating mill research and development.The kind of current airslide disintegrating mill mainly contains disc type airslide disintegrating mill, fluidized bed airflow pulverizer, circulation pipe air flow crasher and rake airslide disintegrating mill etc., and wherein the most frequently used is disc type airslide disintegrating mill and fluidized bed airflow pulverizer.Disc type airslide disintegrating mill has the high advantage of crush efficiency, but grain size grading precision is lower; And although fluidized bed airflow pulverizer effectiveness of classification is higher, crush efficiency is lower, price is higher, and in addition because its volume is comparatively large, therefore floor space is large and install and inconvenient maintenance.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of operation and installation convenient and crush efficiency and the high disc type airslide disintegrating mill of grain size grading precision.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of disc type airslide disintegrating mill, by frame, seat ring, upper cover, lower cover and feeding device composition, described seat ring and upper, by bolted between lower cover, inner formation pulverizing-grading room, pulverizing-grading room top is provided with exhaust outlet, bottom is provided with discharging opening, gas-distribution pipe is provided with outside seat ring, pass through the tangentially pulverizing nozzle be arranged on seat ring after compressed air is entered by gas-distribution pipe and enter pulverizing-grading room, described feeding device is by hopper, feed introduction and Venturi tube composition, feed introduction is connected with gas-distribution pipe by reinforced flexible pipe, Venturi tube extends to pulverizing-grading room.
Be provided with pulverizing pressure valve between described gas-distribution pipe and seat ring, be provided with feed pressure valve between gas-distribution pipe and feed introduction, reinforced flexible pipe is provided with feed pressure table, pulverizes nozzle and is provided with pulverizing Pressure gauge.
Operation principle of the present utility model:
The airflow injection that material in hopper is shot out by feed introduction is to Venturi tube, material in Venturi tube and air-flow mix and enter pulverizing-grading room after supercharging, there is the mutual impact of material of certain speed, and adjacent two air-flows pulverized between nozzle form the little eddy flow of some strong rotations, material in little eddy flow carries out acute impact, thus reaches the object of pulverizing; Pulverized particle is brought graded region into by eddy flow and is moved as a laminar flow and carry out classification, and the particle being wherein greater than Cut size turns back to disintegrating area to be continued to pulverize, and the particle being less than Cut size with air-flow by outside exhaust outlet discharge machine.
The beneficial effects of the utility model are: structure is simple, reasonable in design, easy to operate, by feed introduction and the setting of pulverizing nozzle, material is fully pulverized, material after pulverizing moves as a laminar flow and carries out classification, the particle meeting Particle size requirements is discharged from discharging opening, thus improves grain size grading precision.
Accompanying drawing illustrates:
Fig. 1 is structure front view of the present utility model;
Fig. 2 is structure top view of the present utility model.
Wherein: 1-frame; 2-seat ring; 3-upper cover; 4-lower cover; 5-feeding device; 6-bolt; 7-pulverizing-grading room; 8-exhaust outlet; 9-discharging opening; 10-gas-distribution pipe; 11-pulverizes nozzle; 12-hopper; 13-feed introduction; 14-Venturi tube; 15-feeds in raw material flexible pipe; 16-pulverizes pressure valve; 17-feed pressure valve; 18-feed pressure table; 19-pulverizes Pressure gauge.
Detailed description of the invention:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Fig. 1, shown in 2, a kind of disc type airslide disintegrating mill, by frame 1, seat ring 2, upper cover 3, lower cover 4 and feeding device 5 form, seat ring and upper, fastening with bolt 6 between lower cover, inner formation pulverizing-grading room 7, pulverizing-grading room top is provided with exhaust outlet 8, bottom is provided with discharging opening 9, gas-distribution pipe 10 is provided with outside seat ring, pass through the tangentially pulverizing nozzle 11 be arranged on seat ring after compressed air is entered by gas-distribution pipe and enter pulverizing-grading room, feeding device is by hopper 12, feed introduction 13 and Venturi tube 14 form, feed introduction is connected with gas-distribution pipe by reinforced flexible pipe 15, Venturi tube extends to pulverizing-grading room.Be provided with between gas-distribution pipe and seat ring and pulverize pressure valve 16, be provided with feed pressure valve 17 between gas-distribution pipe and feed introduction, reinforced flexible pipe is provided with feed pressure table 18, pulverizes nozzle and is provided with pulverizing Pressure gauge 19.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
