Abstract
The utility model discloses a feeding cabin material level caution device of a silicon carbide micro-powder grading machine and belongs to the technical field of silicon carbide micro-powder grading machines. The feeding cabin material level caution device of the silicon carbide micro-powder grading machine comprises a feeding cabin, wherein the feeding cabin is internally provided with a first position sensor for detecting the height of a bottom material limiting position of materials in the feeding cabin; and the first position sensor is electrically connected to a control unit of the silicon carbide micro-powder grading machine and the control unit is connected with an alarm. By utilizing the structure, when the materials in the feeding cabin are reduced to the height of the bottom material limiting position, the feeding cabin material level caution device alarms so that workers can treat in time; and the height of the bottom material limiting position needs to be set in the time from alarming to the treatment of workers, and an air hole is not formed by the materials in the feeding cabin.
Description
Technical field
The utility model relates to silicon carbide micro-powder grader technical field, relates in particular to a kind of silicon carbide micro-powder grader feeding warehouse material level alarming device.
Background technology
When the silicon carbide micro-powder grader carries out extension set the variation of the gas field in the machine, negative pressure air pressure and air-flow velocity is had strict requirement, and the three interdepends, therefore; The stability of gas field, air pressure and intake is particularly important, and in traditional grader, feeding warehouse is communicated with feed pipe; Feed pipe is sent into material in the stage equipment in downstream through negative-pressure adsorption, when the material of feeding warehouse is less than to a certain degree, will form the cavity of certain area in the middle of the material; Make feed pipe pass through feeding warehouse and be communicated with ambient atmosphere, this cavity is commonly referred to wind-tunnel, and the staff can not in time find to replenish material; Wind-tunnel also can be increasing; Will destroy the balance of gentle of grader internal gas pressure, cause the product granularity skew, influence the quality of product.
Summary of the invention
The utility model technical matters to be solved is: a kind of silicon carbide micro-powder grader feeding warehouse material level alarming device is provided; It can monitor the height of material in the feeding warehouse; Will report to the police and inform the staff when material is lower than lowest limit controlling level, make the staff can in time adjust the quantity of material in the feeding warehouse, prevent to produce wind-tunnel; Thereby make grader stable, improve the quality of product.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of silicon carbide micro-powder grader feeding warehouse material level alarming device; Comprise feeding warehouse; Be provided with the primary importance sensor that detects the lowest limit controlling level of material in the said feeding warehouse in the said feeding warehouse; Said primary importance sensor electrical is connected on the control module of silicon carbide micro-powder grader, and said control module is connected with alarm, and said lowest limit controlling level can in time add materials for the staff receives the report for police service and prevent in feeding warehouse, to form the height of wind-tunnel; Usually set a little higher than material forms wind-tunnel in feeding warehouse height, concrete setting will be confirmed according to charging rate, staff's reaction time etc. in the actual production process.
As a kind of preferred; The charging aperture place of said feeding warehouse is connected with the second place sensor of the high-order controlling level that detects said feeding warehouse; Said second place sensor electrical is connected on the control module of silicon carbide micro-powder grader, and said high-order controlling level is the height of material near the charging aperture of feeding warehouse, guarantee staff's signal that receives the report for police service; Can in time handle making material not exceed discharging opening to cause material to overflow, specifically also will confirm according to actual production process.
As a kind of preferred, said alarm is an audible-visual annunciator.
As a kind of preferred, said primary importance sensor and second place sensor are level-sensing device.
Owing to adopted technique scheme, when the material in the feeding warehouse arrived lowest limit controlling level, the primary importance sensor will send signal to control module; Control module is handled alarm work, and alarm equipment alarm is notified the staff, and the staff can add materials in feeding warehouse timely; The supply that guarantees material is stable; Can not produce wind-tunnel, thereby guarantee the balance of gentle of grader internal gas pressure, improve the quality of product.
Because the charging aperture place of said feeding warehouse is connected with the second place sensor of the controlling level that detects said feeding warehouse; When the material of feeding warehouse arrives high-order controlling level; Second place sensor sends to control module with signal; Control module control alarm sends signal, notifies the staff in time to handle.
Because alarm is an audible-visual annunciator, can play the warning effect better, the staff can't hear can be seen, and can't see to listen to obtain, and notifies the staff to greatest extent.
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, feeding warehouse; 2, second place sensor; 3, the primary importance sensor; 4, feed pipe; 5, control module; 6, alarm.
Embodiment
Shown in accompanying drawing; A kind of silicon carbide micro-powder grader feeding warehouse material level alarming device comprises feeding warehouse 1, and the discharging opening of said feeding warehouse 1 is communicated with feed pipe 4; The material of feeding warehouse 1 flows into feed pipe 4; Through being provided with the primary importance sensor 3 that detects the lowest limit controlling level of material in the said feeding warehouse 1 in the said feeding warehouse 1, said primary importance sensor 3 is electrically connected on the control module 5 of silicon carbide micro-powder grader, and said control module 5 is connected with alarm 6; In order to improve the effect of warning; Make the staff can receive warning message, said alarm 6 is generally audible-visual annunciator 6 as far as possible, and the charging aperture place of said feeding warehouse 1 is connected with the second place sensor 2 of the high-order controlling level that detects said feeding warehouse 1; Said second place sensor 2 is electrically connected on the control module 5 of silicon carbide micro-powder grader, and said primary importance sensor 3 is level-sensing device with second place sensor 2.
The principle of work of the utility model is: configure the lowest limit controlling level of primary importance sensor 3 detections and the high-order controlling level that second place sensor 2 detects, and feeding warehouse 1 charging in feed pipe 4, the material in feeding warehouse 1 arrives lowest limit controlling level; Primary importance sensor 3 will send signal to control module 5, and control module 5 is handled alarm 6 work, alarm 6 alert notice staff; The staff can add materials in feeding warehouse 1 timely, guarantees that the supply of material is stable, can not produce wind-tunnel; Thereby guarantee the balance of gentle of grader internal gas pressure; Improve the quality of product, when the material of feeding warehouse 1 arrived high-order controlling level, second place sensor 2 sent to control module 5 with signal; Control module 5 control alarms 6 send signal; Notify the staff in time to handle,, cause waste in order to avoid material overflows.
