The utility model aims at providing a can in time discover disconnected ore through disconnected ore alarm when can add the ore deposit phenomenon at the fluidized bed furnace, thereby guarantee the continuous stability of technology production.
The utility model discloses a main technical scheme: the utility model provides a be applied to broken ore alarm of sulphuric acid of ore deposit system, includes controller, detector, installing support, its characterized in that: the detector is arranged on the feeding control flashboard above the raw material conveying belt through a mounting bracket, adopts an electrostatic capacitance type proximity switch and is provided with an indicator light; the controller is connected with the detector through a cable, and an audible and visual alarm device is arranged on the controller.
Preferably, the mounting bracket is of an L shape, the vertical end of the mounting bracket is connected with the charging control flashboard, and the horizontal end of the mounting bracket is connected with the detector.
The vertical end is connected with the charging control flashboard, and the horizontal end is connected with the detector through bolts.
The detection end face of the detector is parallel to the surface of the material layer on the raw material conveying belt.
The distance between the end face of the detector and the surface of the feeding layer of the raw material conveying belt is 15 mm.
The utility model discloses detection to disconnected ore deposit adopts electrostatic capacitance formula proximity switch to realize, its working process as follows: when the ore feeder normally runs, the feeding amount of the raw material conveying belt always maintains the thickness (height) required by the process, when the ore feeding amount is abnormal, the thickness of a material layer is changed (usually reduced), when the thickness of the material layer is reduced to about 1cm, the output of the proximity switch is cut off, the relay (the load of the proximity switch) stops working at the moment, the contact is restored to the initial state, namely the normally closed contact is switched on, and after the signal is switched on, the controller sends out an audible and visual alarm signal. When the feeding returns to normal, the output of the proximity switch is switched on, the relay works, the normally closed contact is switched off, the signal is switched off, and the controller stops audible and visual alarm.
The utility model can also be used as a bin full material (material level) alarm. The specific using method comprises the following steps: firstly, the approach switch is fixedly installed at the height of a material level to be controlled, the welding wire of the relay contact of the controller of the instrument is displaced, and the welding wire of the normally closed contact is changed into the welding wire of the normally open contact.
The utility model provides a be applied to sulphuric acid's broken ore alarm is made in ore deposit. The instrument has the characteristics of simple structure, convenience in installation and use, small maintenance amount, high alarm sensitivity, reliability in operation and the like.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Examples
The embodiment comprises an ore breaking alarm applied to the ore sulfuric acid production, and the installation mode is shown in the attached figure 1.
The embodiment is applied to the broken ore alarm of the sulfuric acid made by the mine, mainly comprising a controller (not marked in the figure), a detector 3 and a mounting bracket 5, wherein the detector 3 is mounted on a charging control flashboard 1 above a raw material conveyer belt 7 through the mounting bracket 5, and the detector 3 adopts an electrostatic capacitance type proximity switch and is provided with an indicator lamp 4; the controller is connected with the detector 3 through a cable, and an audible and visual alarm device is arranged on the controller.
In the embodiment, the detector 3 is connected with the mounting bracket 5 through the fixing bolt 2, the mounting bracket 5 is L-shaped, the vertical end of the mounting bracket is connected with the charging control flashboard 1 through the fixing bolt 2, and the mounting height can be adjusted; the horizontal end is connected with the detector 3 through the fixing bolt 2, and the detector 3 can be detached at irregular intervals, so that the cleaning and the repairing are convenient.
In the embodiment, the detection end face of the detector 3 is parallel and opposite to the material layer plane on the conveying belt, and the detection end face of the detector is 15 mm away from the material layer surface (namely the lower edge of the material layer thickness control gate) on the conveying belt.
In the embodiment, the installation height of the detector (the distance between the detection end face and the material layer surface) is finely adjusted according to the field condition, and the adjustment method comprises the following steps: the adjustment of the detector height can be started both when the charge conveyor belt is running and full of mineral charge. The position of the detector is adjusted according to the actual effective action distance of the detector, firstly, a fixing nut of a mounting bracket of the detector is loosened, the detector is moved up and down, a critical trigger position of the detector is found, and the critical position of the detector can be determined by the on and off of a working indicator lamp 4 on the detector. The working indicator light is on to indicate that the detector has load current output, and the detector is off without current output. After the critical triggering position is determined, the detector is adjusted downwards, namely the detector approaches to the raw material layer by about 15 mm, and the bracket is locked to fix the nut.
The embodiment of the mine breakage alarm realizes the detection of mine breakage by adopting an electrostatic capacitance type proximity switch, and the working process is as follows: when the ore feeder normally operates, the feeding amount of the raw material conveying belt always maintains the thickness (height) required by the process, when the ore feeding amount is abnormal, the thickness of a material layer changes (generally reduces), when the thickness of the material layer is reduced to reach about 1cm, the output of the proximity switch is cut off, the relay (the load of the proximity switch) stops working at the moment, the contact recovers to the initial state, namely the normally closed contact is switched on, and after the signal is switched on, the controller sends out an audible and visual alarm signal. When the feeding returns to normal, the output of the proximity switch is switched on, the relay works, the normally closed contact is switched off, the signal is switched off, and the controller stops audible and visual alarm.
