Abstract
The utility model discloses a feed device of a silicon-carbide fine power classifier, belonging to the technical field of silicon-carbide fine power classification and comprising a frame. A primary feed bin is mounted on the frame, a discharge port of the primary feed bin is in sealed connection with a feed pipe, and the feed pipe is provided with a detection device for detecting feed rate, the detection device being in electric connection with a system control unit. At least one secondary feed bin is also mounted on the frame, and a conveying device controlled by the control unit for conveying materials from the secondary feed bin to the feed pipe is arranged between the secondary feed bin and the feed pipe. In general conditions, the feed pipe is fed by the primary feed bin other than the secondary feed bin, and only if a feed insufficiency of the feed pipe is detected by the detection device, the control unit receives a signal transmitted by the detection device and controls the feed device to start so as to make materials in the secondary bin conveyed to the feed pipe, thereby keeping the feed rate of the feed pipe stable and improving the quality of products.
Description
Technical field
The utility model relates to a kind of silicon carbide micro-powder classifying equipoment, especially designs a kind of feed arrangement of silicon carbide micro-powder grader.
Background technology
In the process of silicon carbide micro-powder grading technology, need lasting, the stable supply of the interior material (being micro mist) of feed pipe of maintenance silicon carbide micro-powder grader, present feed arrangement has only a feeding warehouse to supply with material to feed pipe; Because the characteristic of material itself; And different raw meal particle sizes composition is different, and the discharging opening of feeding warehouse stops up easily, causes material supply to reduce; Material supply is unstable, thereby influences the quality of product after the classification.
Summary of the invention
The utility model technical problem to be solved is: the feed arrangement that the stable silicon carbide micro-powder grader of a kind of material supply is provided.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of feed arrangement of silicon carbide micro-powder grader; Comprise frame, main feeding warehouse is installed on the said frame, the discharging opening of the said main feeding warehouse feed pipe that is tightly connected; Said feed pipe is provided with the checkout gear that detects inlet amount; Said checkout gear is electrically connected on the control module of system, and at least one secondary feeding warehouse also is installed on the said frame, be provided with between said secondary feeding warehouse and the said feed pipe by control module control with the mass transport of said secondary feeding warehouse pay-off to said feed pipe.
As a kind of preferred, said pay-off comprises the discharging opening that is communicated with said secondary feeding warehouse and the secondary feed pipe of said feed pipe, and said secondary feed pipe is provided with the spiral propeller of being controlled by control module.
As a kind of preferred, said checkout gear is a volume control damper, and said volume control damper is installed on the end of said feed pipe.
As a kind of preferred, said secondary feeding warehouse has two.
As a kind of preferred, the diameter of said secondary feed pipe is 1/3 of a feed tube diameter.
Owing to adopted technique scheme, increase at least one secondary feeding warehouse, secondary feeding warehouse is not generally to the feed pipe charging; Has only main feeding warehouse to the feed pipe charging, when having only checkout gear to detect feed pipe charging deficiency, through sending signal to control module; Control module is just controlled feed arrangement and is opened; Mass transport in the secondary feeding warehouse is in feed pipe, thereby the inlet amount in the maintenance feed pipe is stable, improves the quality of products.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1, main feeding warehouse; 2, secondary feeding warehouse; 3, secondary feed pipe; 4, spiral propeller; 5, volume control damper; 6, frame.
The specific embodiment
Shown in accompanying drawing, a kind of feed arrangement of silicon carbide micro-powder grader comprises frame 6; Main feeding warehouse 1 is installed on the said frame 6, and the discharging opening of said main feeding warehouse 1 feed pipe that is tightly connected, said feed pipe are provided with the checkout gear that detects inlet amount; Said checkout gear is electrically connected on the control module of system, and at least one secondary feeding warehouse 2 also is installed on the said frame 6, usually shown in figure; Said secondary feeding warehouse 2 has two, also can arrange 3 or 4 the secondary feeding warehouses 2 that wait other quantity according to actual conditions certainly, be provided with between said secondary feeding warehouse 2 and the said feed pipe by control module control with the mass transport of said secondary feeding warehouse 2 pay-off to said feed pipe; Said pay-off comprises the discharging opening that is communicated with said secondary feeding warehouse 2 and the secondary feed pipe 3 of said feed pipe; Be the convenience of installation and charging, the diameter of said secondary feed pipe 3 is 1/3 of a feed tube diameter, and said secondary feed pipe 3 is provided with the spiral propeller 4 by control module control; Because the feeding manner of feed pipe adopts the mode of negative-pressure adsorption usually; Therefore, said checkout gear is a volume control damper 5, and said volume control damper 5 is installed on the end of said feed pipe; The feed pipe position is blocked by volume control damper 5 and main feeding warehouse 1 in the drawings, and is invisible.
The operation principle of the utility model is: feed pipe adopts the mode of negative-pressure adsorption with the equipment of mass transport to downstream, and under the normal condition, main feeding warehouse 1 charging aperture is connected with feed pipe; Be continuously feed pipe and supply with material, charging rate is slack-off in main feeding warehouse 1, and volume control damper 5 detects air quantity to be changed; Send signal to control module, control module is controlled said spiral propeller 4 and is opened, with the mass transport in the secondary feed pipe 3 to feed pipe; The balance inlet amount; Make inlet amount keep stable, make and produce stable carrying out, the quality of product after the assurance classification.
Claims (5)
