Abstract
The utility model relates to a particle material grading system and aims to solve problems that a present particle material grading system has complicate operation, uneven partition size and low grading efficiency, product cleanness and micro powder content are difficult to be controlled; and the present material grading system has high production cost and a long production period. The particle material grading system mainly comprises an air distribution adjusting valve, a bunker, at least two grading machines in parallel connection, a whirlwind collector, a dust remover and an induced draft fan and further comprises a controller and a pressure sensor. Signals of rotating speed of the induced draft fan and an opening degree of the air distribution adjusting valve in the grading system are collected by the pressure collector and transmitted to the controller; and an automatic frequency converter controls the rotating speed of the induced draft fan and the opening degree of the air distribution adjusting valve. The particle material grading system has simple operation, even partition size and high grading efficiency; by the use of the system, micro powder content can be effectively reduced; product cleanness can be improved; and production period can be shortened and production cost can be reduced.
Description
Technical field
The utility model relates to a kind of granule materials hierarchy system, belongs to gradation technical field.
Background technology
Common hierarchy system is comprised of grader, cyclone collector, deduster, air-introduced machine, and grader is mainly used in the classification of the high rigidity materials such as carborundum, corundum, diamond.The grading technology of grader is ripe already, but in actual production, silicon carbide micro-powder is produced and recycle in engender some problems: the problems such as grading plant is complicated, the production cycle is long, production cost is high, the accurate numerical value of rotating speed neither one of air-introduced machine, micro mist cleannes are not high, as invented CN 102580928 A.Under the effect of air-introduced machine, air quantity is too large, causes the indoor powder skewness of extension set, has affected granularity and the distribution of finished product; Air quantity is too small, and material can not be pulled away because carrier is not enough, is trapped in grading room, has affected grading effect.Because customer service is more and more higher to quality requirement, and air quantity, blast can not get effective control, cannot to the requirement of product, reach indices according to different material sources and different client, cause size distribution inequality, micro mist cleannes in powder to be difficult to control, directly cause the raising of production cost and the reduction of product quality.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of easy and simple to handle, partition size is even, efficiency is high, can effectively reduce powder content and improve product cleannes, reduces production costs simultaneously, shortens the granule materials hierarchy system of production cycle.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Granule materials hierarchy system, comprise the air distribution control valve, feed bin, the grader of at least two series connection, cyclone collector, deduster, the air-introduced machine that connect successively, it is characterized in that, also comprise controller, be correspondingly respectively installed on the pressure sensor on grader, cyclone collector, deduster, air quantity, wind pressure value in the grader that described controller collects according to each corresponding pressure sensor, cyclone collector, deduster, regulate the rotating speed of air-introduced machine and the open degree of air distribution control valve.
Described air distribution control valve is pneumatic control valve or electric control valve.
Described controller is via the rotating speed of Frequency Converter Control air-introduced machine.
Described controller is PID control instrument.
The utlity model has following actively useful effect:
1. this hierarchy system is simple in structure, easy and simple to handle; Due to pressure sensor being installed, can automatically regulate according to air quantity, wind pressure value the open degree of rotating speed and the air distribution control valve of air-introduced machine simultaneously, improve granularity and the precision of classification, improve product cleannes, improve the yield and quality of product.
2. be applicable to different material sources, particularly SiC micro mist, can carry out classification according to the requirement of different customer services, reduces production cost simultaneously, shortens the production cycle, raises labour efficiency.
3. air quantity, the blast that can be widely used in the relevant powder industry graders such as silicon carbide micro-powder are controlled.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of granule materials hierarchy system;
Fig. 2 is a kind of Automatic Control Theory figure of granule materials hierarchy system;
In figure: 1-feed bin, 2-the first grader, 3-the second grader, 4-cyclone collector, 5-deduster, 6-air-introduced machine, 11-air distribution control valve, 7,8,9,10 is pressure sensor.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1: a kind of granule materials hierarchy system, as Fig. 1, shown in 2, comprise the air distribution control valve 11 connecting successively, feed bin 1, two graders that are cascaded, cyclone collector 4, deduster 5, air-introduced machine 6, also comprise PID control instrument, the corresponding deduster 5 that is installed on, cyclone collector 4, the second grader 3, pressure sensor 7 on the first grader 2, 8, 9, 10, described grader can arrange two and be cascaded, also can arrange three, certainly under the prerequisite allowing at pressure, more graders also can be set to be cascaded, the grader that described controller collects according to each pressure sensor, cyclone collector 4, air quantity in deduster 5, wind pressure value, regulate the rotating speed of air-introduced machine 6 and the open degree of air distribution control valve 11.
Above-mentioned granule materials hierarchy system specific works process: as shown in Figure 1, 2, material enters the first grader 2 by feed bin 1, the material that makes to meet the qualified fineness of the first grader 2 classification requirements enters the second grader 3 under the effect of ascending air, through the second grader 3 gains material granularities refinement, more even more, fine powder enters cyclone collector 4 subsequently, a small amount of micro mist enters deduster 5, and purified gas is discharged by air-introduced machine 6.The air quantity in grader wherein, wind pressure value is through pressure sensor 7, 8, 9, 10 force value that detect, change 0-20MA current signal or 0-5V voltage signal into, be delivered to PID Displaying Meter, through computing and set definite value (Air Quantity Required, the size of blast) compare, output control signal is controlled frequency converter, further by the rotating speed of Frequency Converter Control air-introduced machine 6, when blast is crossed Wind Volume hour, the signal that PID Displaying Meter transmits according to sensor regulates the open degree of air distribution control valve 11 automatically, otherwise reduce open degree, thereby make air quantity in hierarchy system, the size of blast meets the requirement of silicon carbide micro-powder to micro-powder graded granularity, reduce powder content, improve the cleannes of product.
