Abstract
The invention discloses an emulsifier safe running cutting off monitoring device used in explosive product line. The plate is rigidity material and has sliding surface. One end of the plate is under the outlet of the emulsifier, and the other end is connected to the up end of spring. The down end is fixed. The signal collector is located on the up end that the plate connecting to the spring to collect cut off signal, and the controller process the signal and send out alarm or stop instruction. Comparing to the existing monitor device, it could continuously and reliably auto monitoring. It could decrease the errors by man judgment and effectively improves the safety of the device.
Description
Technical field
The invention belongs to explosive production safety monitoring technology field, be specifically related to a kind of cutout safety monitoring assembly of emulsion explosive production line emulsor.
Background technology
Along with society and expanding economy, civil engineering is very fast to the demand growth of explosive, all reaches annual growth in recent years more than 30%.Emulsion explosive is the widely used explosive of the quick-fried industry of the present people, has the characteristics of efficient and environmental protection.The core equipment of emulsion explosive production line is an emulsor, comprises just emulsor and smart emulsor.How the emulsor working order directly influences the output and the quality of explosive.Simultaneously, emulsor is again unique equipment that the high speed machine motion is arranged in the whole production line, therefore, also is the most dangerous equipment.Emulsor can blast under the situation of material cut-off.At present, domestic have more than 100 of an emulsion explosive production line, and three blast accidents had taken place over nearly 3 years, suffers heavy losses.Technical evaluation shows that it is to be caused by the emulsor material cut-off that explosion hazard is together arranged.As seen, monitoring emulsor mass flow state is reported to the police under error state (ERST) or is stopped in emergency, and has very important meaning for support personnel and property safety.
The mass flow of emulsion explosive production line monitoring at present is main to be relied on artificial or regularly visual inspection of video system, reacts untimely, dangerous high, does not still have the security of the long-term continuous monitoring emulsor of means so far.
Summary of the invention
The object of the present invention is to provide a kind of safety cut-off monitoring apparatus or emulsifier that is used for explosive production line, this device can be effectively, safely to emulsor carry out continuously, disconnection state is monitored automatically reliably.
A kind of safety cut-off monitoring apparatus or emulsifier that is used for explosive production line provided by the invention; it is characterized in that: flat board is for rigid material and have smooth surface; a dull and stereotyped end is positioned at the below of emulsor material outlet; the other end links to each other with the upper end of spring; the lower end of spring is fixed, and signal picker is positioned at the top of a dull and stereotyped end that links to each other with spring, is used for gathering the cutout signal; controller is used for the cutout signal is handled, and sends and reports to the police or stop instruction.
Signal picker can be selected contact switch or displacement sensor for use.
Compare with existing artificial video monitoring means; the present invention can make things convenient for the disconnection state of key equipment emulsor in the emulsion explosive production line continuously, reliable automated security monitor; when stopping, emulsor in time scents a hidden danger; and capable of automatic alarm and chain shutdown; need not again with artificial means direct viewing or closely by the video remote viewing equipment; the possibility of reduction personnel naked eyes monitoring error and response lag and the danger of direct on-site supervision effectively improve device security.
Description of drawings
Fig. 1 is the structural representation of apparatus of the present invention.
Embodiment
Emulsor is the mechanical means of high speed rotating, when cutout takes place material, can produce the steam of High Temperature High Pressure in sealed chamber, blasts.Therefore, can avoid emulsor to explode by the continuous monitoring whether material is stopped because of cutout takes place.The present invention be main means with emulsor cutout monitoring, in emulsor outlet installation apparatus of the present invention, the emulsor signal that stops is converted into and can monitors electrical signal.When emulsor moves, gather the cutout signal in real time, when controller received the cutout signal, the expression mass flow was unusual, and forecast and auto stop prevent that emulsor from producing accidental explosion in advance.
The present invention is further detailed explanation below in conjunction with accompanying drawing and example.
As shown in Figure 1, apparatus of the present invention comprise flat board 2, signal picker 3, spring 4 and controller 5.An end of dull and stereotyped 2 is positioned at the below of the material outlet of emulsor 1, and the other end links to each other with the upper end of spring 4, and the lower end of spring 4 is fixed.Signal picker 3 is positioned at the top of a dull and stereotyped end that links to each other with spring 4.Dull and stereotyped 2 adopt rigid material, and have smooth surface, and signal picker 3 is used for gathering the cutout signal, can select devices such as contact switch or displacement sensor for use.Controller 5 is used for receiving the cutout signal, and the cutout signal is handled, and sends and reports to the police or stop instruction.Controller 5 can be warning lugs or information processing computer etc.
Dull and stereotyped 2 keep a kind of steady state when not being subjected to the impact of material, change into another kind of steady state when it is subjected to the bump of material.Signal picker is gathered the variable signal of dull and stereotyped state, and is translated into level signal and is sent to controller 5 and monitors in real time, when monitoring the cutout signal, and chain shutdown.
Specifically, when signal picker is selected the explosion-proof type contact switch for use, its principle of work is: during the production line works better, the outlet material freely falling body enters collection funnel, clash into smooth plates continuously, by the leverage extension spring, drive the switch contact closure, provided the effusive level signal of material; When the situation of material cut-off occurring, under the effect of spring force, switch contact can disconnect, and provides the level signal that no streams goes out.By detecting high-low level, the cutout signal can be converted into the switching value signal, when the cutout level that monitors surpasses certain hour continuously, then judging having cutout to take place, and controller 5 sends reports to the police or promptly stops production line, thereby reaches the security monitoring of production line.
If signal picker is to select displacement sensor for use, its principle of work is: when production line stopped production, no streams amount, the dull and stereotyped steady state that keeps was adjusted displacement sensor, and the distance that can demarcate its measurement is 0.When the production line works better, the outlet material freely falling body enters collection funnel, clashes into smooth plates continuously, and displacement sensor can be measured the distance under the material situation.When the situation of material cut-off occurring, the distance that displacement sensor goes out is 0.Controller has judged whether that by the distance of judgement displacement sensor cutout takes place, and when judgement had cutout to take place, controller 5 sent warning or promptly stops production line, thereby reaches the security monitoring of production line.
The present invention is converted into the electrical signal that computer can be monitored with the Flow of Goods and Materials situation of emulsor outlet pipe, by with the chain security that ensures emulsor of Controlling System.
