Abstract
The utility model discloses an automatically block-proof flat jet mill. A couple of automatically block-proof wall scrapers are located in the working cylinder of the device, to remove the materials adhering to the working cylinder wall timely, which can prevent glutinous materials from blocking the working cylinder, so as to guarantee a continuous crushing process, thereby the production capacity and the product quality of the mill are increased greatly.
Description
Technical field
The utility model belongs to a kind of mechanical crushing device, particularly a kind of air flow super device.
Background technology
Airslide disintegrating mill is the device that a class prepares superfine powder, the airslide disintegrating mill of present industrial application mainly contains five types of (" ultra-fine grinding principle, process equipment and application " books of writing referring to Zheng Shuilin, Chinese building material industry publishing house, in May, 1993 front page P164～168), airslide disintegrating mill is known as airflow milling traditionally.The inventor finds the most general flat or horizontal circle disc type airflow milling of present industrial application (as the flat airflow milling of JGM series of East China University of Science's production), there is shortcoming poor for applicability in actual applications, there is following point in (as titanium dioxide) when pulverizing viscous material when flat airflow milling is tried out: 1. easily produce sticking wall, stop up the working cavity of pulverizer, cause and pulverize the operating mode severe exacerbation, product quality is descended; 2. crushing process can not carry out continuously, and general work must be shut down block clearing once after the kind in 30～40 minutes, had increased many troubles to crushing operation; 3. because the material of sticking wall caking can not use, cause the raw material loss to strengthen.Therefore, branch of industry wishes that relevant scientific and technical personnel study improvement, improving the applicability of existing flat airflow milling, thereby satisfies the requirement of various viscous material super-fine processing.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, provides a kind of flat airslide disintegrating mill of energy automatic block-resistant, to satisfy the requirement of various viscous material super-fine processing.
Design of the present utility model is such:
The inventor is by pulverizing viscous material repetition test, observation to existing flat airslide disintegrating mill, find that viscous material very easily adheres on the upper and lower wall of crusher cavity, and constantly thicken, extend, little by little stop up the working cavity of pulverizer, cause the severe exacerbation of pulverizing operating mode, can cause complete machine can not work fully when serious.For this reason, inventor's design is provided with a pair of wall scraper in the working cavity of pulverizer, they near the upper and lower wall of working cavity, are removed the material that adheres on the wall in time by rotatablely moving of they, thereby have prevented from phenomenon of blocking to occur in the pulverizer working cavity respectively.In general, because the lower wall surface adhesion of working cavity is more serious, therefore suitable big near its rotary speed of wall scraper of lower wall surface, between the also upper and lower in other words wall scraper certain differential motion should be arranged, this can realize technically easily.
The utility model also is achieved in that
In flat airslide disintegrating mill working cavity, near upper and lower wall place, be provided with a pair of anti-blocking wall scraper, nationality helps the little shape motor that is arranged on flat airslide disintegrating mill hull outside top, the work of drive differential case, and then the outrigger shaft by gear-box drives wall scraper respectively and carries out differential rotatablely moving, thereby can remove the material that adheres on the wall in time, prevents the generation of clogging in the pulverizer working cavity effectively.
Further illustrate content of the present utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of the flat airslide disintegrating mill of energy automatic block-resistant
Wherein: the 1-micromotor;
The 2-differential case;
A, b-are respectively the outrigger shaft of differential case;
The last wall scraper of 3-(in aggregates with pulverizer classification circle), it is arranged on the upper wall of working cavity
Near, be fixed on a axle of differential case, and make low-speed rotation by the drive of a axle;
4-(pulverizer) working cavity;
5-(pulverizer) main jet;
Wall scraper under the 6-, it is arranged near the lower wall of working cavity, is fixed in differential case
On the b axle, and drive by the b axle and to make low-speed rotation;
7-(pulverizer) discharging opening.
As seen from Figure 1: the said stream pulverizer of the utility model is mainly by micromotor (1), differential case (2) and flat airslide disintegrating mill three parts are formed, on the casing both sides of flat airslide disintegrating mill, be arranged with a main jet (5) respectively, center, below at the working cavity (4) of pulverizer is provided with discharging opening (7), material sprays into working cavity (4) through main jet (5) and collides pulverizing under air-flow drives, product after the pulverizing is discharged by discharging opening (7), improvement part is: close last in flat airslide disintegrating mill working cavity (4), the lower wall place is provided with wall scraper (3) respectively, following wall scraper (6), they are fixed in differential case outrigger shaft (a) respectively, (b) on, and differential case (2) positioning and fixing is above flat airslide disintegrating mill casing, its two concentric outrigger shaft (a), (b) stretch into the working cavity (4) from the center of casing, outrigger shaft (a) and last wall scraper (3) Joint, outrigger shaft (b) and following wall scraper (6) Joint, and on driving, following wall scraper (3), (6) make differential motion; The shell of differential case (2) top is provided with the affixed micromotor (1) that matches with the main shaft of differential case (2).
In a word, be arranged on a pair of wall scraper (3), (6) in the working cavity (4), drive differential case (2) work by micromotor (1), outrigger shaft (a) and (b) by differential case drive wall scraper (3) respectively again, (6) make low-speed rotation, in time remove the material that adheres on the pulverizer working cavity inwall, prevented that automatically the phenomenon of working cavity from appearring stopping up in viscous material in crushing process.
The differential motion of upper and lower wall scraper has not only satisfied the mission that timely removing adheres to the material on the working cavity inwall separately in addition, and helps improving the crush efficiency of crushing process.
The specific embodiment
Getting homemade specification is the flat airflow milling of JGM-H400, try out in the ultra-fine grinding of viscous material (titanium dioxide), pulverizing pressure is 0.7MPa～0.8MPa, charging particle diameter yardstick is-325 orders, and average product is 30Kg/h, and loss is 10%, 40 fens kinds of operation will be opened the cavity block clearing once at most, can not continuous operation, and the quality of product is difficult to guarantee that average grain diameter is 0.8 μ m in the time of preferably.
With the airflow milling of above-mentioned specification, the structural shape of showing according to design of the present invention and Fig. 1 undergoes technological transformation, and is provided with a pair of wall scraper in working cavity, and wherein going up the wall scraper rotating speed is 20 rev/mins, and following wall scraper rotating speed is 30 rev/mins.Because wall scraper turns round continuously, has avoided sticking wall, the obstruction of viscous material in the crushing process, has guaranteed that the working cavity flow field is unobstructed, the material grinding of tackifying effect and quality, crushing process is able to normally carry out continuously.Facts have proved: the utility model device, under same pulverizing pressure and charging particle diameter, not only output can increase to 100Kg/h, loss reduces to 2%, continuous operation normally, and the quality of effect of pulverizing and product also obviously improves the average grain diameter of product＜0.5 μ m, as seen the said pulverizer of the utility model has significant technique effect, has effectively promoted the technological progress of ultra-fine grinding engineering.
