The utility model has the advantages that 1, the material inlet tube is 45 degrees inclined downwards, to jet micro powder at high and uniform speed into the classification area, to effectively improve classify accuracy, 2, the airflow channels output material at upper without changed direction at outlets, to effectively improve classify effect, 3, the utility model has high production efficiency and low production cost.
Description
(1) technical field
The utility model relates to a kind of jet classifying machine, particularly a kind of handstand tilting jet classifying machine.
(2) background technology
The jet classifying machine is mainly used in the classification of subparticle, as far back as the propositions such as RUMPF professor HANS by Germany in 1975, (sees patent No. DE 19752538190,19750827 for details; And US4153541); Loflier subsequently, F. and K.Maly go up open at Symposiumon PowderTechnology D2 (1981), and by Nittetsu Kogyo in commercial sale; Okuda in addition, S. and Yasukuni, J. goes up the category that disclosed graders also belong to the jet classifying machine at Proc.Of InternationalSymposium on Powder Technology 81,771 (1981).The jet classifying machine is well used in ink powder manufacturing field, and some various jet classifying machines through transforming occurred in conjunction with the manufacture characteristic of ink powder.But existing jet classifying machine, its version is: the feed pipe that 1) stretches into the jet classifying district is and is horizontally disposed with or vertically is provided with; 2) change into level or vertical direction immediately at the discharging opening place of grader throughput direction.The shortcoming of this version is that effectiveness of classification is restricted, and is ultra micro powder about 1 micron when carrying out classification for average grain diameter particularly, and effectiveness of classification obviously reduces, and does not reach the classification requirement.When so production at present requires extremely strict super fine to size distribution, still generally adopt the multistage subsider to carry out the classification of wet type gravitational settling, and this stage division floor space is big, production efficiency is low, effectiveness of classification is poor, waste great amount of water resources and thermal resource, has increased manufacturing cost greatly.
(3) utility model content
The purpose of this utility model is at the problems referred to above, provides a kind of super fine is had handstand tilting jet classifying machine higher effectiveness of classification, novel structure.
The technical solution of the utility model:
A kind of handstand tilting jet classifying machine is made up of grader body and feed arrangement; The grader body regulates cutter by 6 block objects, two blocks of side plates, two classifications and trip bolt is formed, 5 gas channels of 6 block bodies formation after fastening, and wherein 3 gas channels link to each other with 3 discharging openings respectively, and 2 gas channels communicate with atmosphere; Feed arrangement is made up of hopper, compressed air inlet pipe and the feed pipe that stretches into the jet classifying district, it is characterized in that: the feed pipe that stretches into the jet classifying district with respect to the body plane for being obliquely installed; 3 gas channels of discharging opening are set to discharging upward and do not change direction in the exit at once.
A kind of above-mentioned handstand tilting jet classifying machine is characterized in that: the feed pipe that stretches into the jet classifying district is the setting of inclination miter angle with respect to the body plane.
A kind of above-mentioned handstand tilting jet classifying machine is characterized in that: the gas channel setting of the discharging opening of fines with respect to the body plane for vertically upward.
A kind of above-mentioned handstand tilting jet classifying machine is characterized in that: the throughput direction of 3 gas channels in the exit changes point and is not less than 200 millimeters with the distance that exports.
Operation principle of the present utility model: the raw material micro mist enters from hopper in the feed pipe of downward-sloping 45 degree vertically downward, compressed air is spurted in the feed pipe by inlet tube, in feed pipe, micro mist is accelerated to certain terminal velocity, injects the jet classifying district equably; Micro mist is with induced draft flight (induced draft is formed by the attraction of the air-introduced machine that connects three discharging openings), under the influence of Coanda effect, bend, wherein coarse granule is because inertia is big, be not easy to be bent, so the radian of flight is bigger, the gas channel of coarse granule discharging opening will be entered, fine grained is because its inertia is little, changing direction easily bends, and enter the gas channel of fine grained discharging opening, and middle particle enters gas channel between the two, and the raw material micro mist just is classified into meal, middle powder, the powder of three kinds of particles of fine powder; Regulating cutter by the rotation classification can be to meal, middle powder, and the particle diameter and the yield of fine powder three parts are regulated.
The utility model has the advantages that: 1) owing to micro mist enters from hopper in the feed pipes of downward-sloping 45 degree vertically downward, in being compressed the air accelerator, the initial velocity that micro mist falls from hopper with finally leave the angle that terminal velocity that feed pipe enters the jet classifying district becomes miter angle, compare with traditional jet classifying machine, the suffered micro mist its own inertial resistance of this feed process is less, micro mist is quickened more fully, speed with higher homogeneous is spurted into graded region, can improve effectiveness of classification effectively.2) because 3 gas channels of jet classifying machine discharging opening are set to discharging upward, make the flight path of meal, middle powder, fine powder not intersect, simultaneously owing to be subjected to the influence that is directed downwards of particle gravity in the jet classifying district, desirable flight path will be helped to form, grading effect can be improved effectively.3) 3 of discharging opening gas channels do not change direction at once in the exit, to the stability influence minimum of upstream grader flow field, can effectively improve effectiveness of classification.4) production efficiency height, low cost of manufacture.
