Abstract

The utility model provides a protector for crusher blocking, which comprises a metal detection board, an approach switch and a PLC. The utility model adopts the approach switch and makes full use of the control function of the PLC, the protection to the motor when the crusher is blocked is realized, the alarm of crusher blocking is realized, and the labor intensity of the operating staff is reduced at the same time.

Description

Disintegrating machine rotation-clogging protection device
Technical field
The utility model relates to a kind of disintegrating machine rotation-clogging protection device, relates in particular to the disintegrating machine rotation-clogging protection device of a kind of PLC of utilization (Programmable Logic Controller).
Background technology
Platform gold, mine, building and railway interests usually use various disintegrating machines to come breaking ores or rock.The disintegrating machine stall often takes place in process of production, is easy to cause the accident of burn-down of electric motor to take place.
Cause the main cause of disintegrating machine stall to have: the batcher feed is inhomogeneous, lump material more for a long time some hard foreign material sneak into, enter disintegrating machine from handpicking belt; When inventory is big, thereby ironware is not picked up by tramp iron separator and enters disintegrating machine.Above situation all may cause disintegrating machine generation stall, as fails to be handled timely, can and then cause burn-down of electric motor, causes damage.
Therefore, cause the situation of burn-down of electric motor, need provide a kind of economic, practical disintegrating machine rotation-clogging protection device to detect and to provide protection/warning to disintegrating machine stall situation for preventing the disintegrating machine stall.
Find in the practice that it is less feasible with the method under the ironware under the material is inhaled to improve suction to reduce the tramp iron separator suspension height, this is because such words bulk materials and long ironware are difficult to abandon iron belt by tramp iron separator.It is also less feasible only to report to the police when the disintegrating machine stall, and this is because the crushing plant noise is very big, is difficult to hear alarm sound in running.
The protective device of shutdown/warning when the utility model proposes a kind of disintegrating machine stall.
The utility model content
Protection when realizing the disintegrating machine stall the utility model proposes a kind of disintegrating machine rotation-clogging protection device.
This device comprises that a metal detection plate, one are near switch and a PLC; described metal detection plate is installed on the disintegrating machine synchromesh gear; describedly be installed near the synchromesh gear in the distance of reaction near switch; described PLC links to each other near switch with described; described PLC comprises computing module and judge module; computing module is by the rotating speed of setting that calculates described synchromesh gear blanking time; judge module is judged the generation stall when the rotating speed of the synchromesh gear that computing module calculated reduces, this moment, PLC sent halt instruction to the disintegrating machine that is attached thereto.
Preferably, described PLC is installed in the shell of described synchromesh gear/put.
Preferably, be 2 seconds the blanking time of described setting.
Preferably, described PLC also comprises a relay, and this relay inserts disintegrating machine and drives the loop, when judging the generation stall, and the described actuating of relay, normally closed contact disconnects, and disintegrating machine is shut down.
Preferably, this device also comprises alarm, and described relay also inserts the siren loop, when judging the generation stall, and the described actuating of relay, the normal opened contact closure, siren sends alarm signal.
The utility model adopts near switch and has made full use of the control function of PLC, can realize the monitoring to the disintegrating machine stall, when realizing the disintegrating machine stall to the protection of motor.Whether simultaneously, alleviated post personnel's labour intensity, originally operating personnel get disintegrating machine operation at any time, only need current check the following stated normally just passable near switch behind application the utility model.Therefore, the utility model device applying flexible, its enforcement not only can reduce the economic loss that the damage of the motor that causes because of the disintegrating machine stall in the production brings, reduced labor intensity of operating personnel, prolong the service life of disintegrating machine, guaranteed the safety of production and carrying out smoothly of ordinary production.
Description of drawings
Read in conjunction with the accompanying drawings, the detailed description of specific embodiment of the utility model is more readily understood.In the accompanying drawing:
Fig. 1 is the operation principle block diagram of the utility model specific embodiment disintegrating machine rotation-clogging protection device.
The specific embodiment
The utility model embodiment is the rotation-clogging protection device that for example is used for the raw coal disintegrating machine.The metal detection plate of rotation-clogging protection device of the present utility model is installed on the position that does not influence synchromesh gear work on the disintegrating machine synchromesh gear, as the side of synchronous gear.Near near the position of passing through that switch is installed in the synchromesh gear, can periodically senses the metal detection plate when synchromesh gear moves, for example be installed in the synchromesh gear shell or put, can certainly be installed on other fixtures in the distance of reaction.In a word, the not only satisfied normal operation that detects needs but also do not influence disintegrating machine in its installation site.Link to each other with a PLC near switch.This PLC also inserts disintegrating machine by a relay and drives loop and siren loop.
The working method of the disintegrating machine rotation-clogging protection device of the utility model specific embodiment is described below with reference to Fig. 1:
When disintegrating machine ran well, its synchromesh gear was along with disintegrating machine rotates, and check-out console periodically near near switch, is passed to the PLC pulse signal near switch periods, and this PLC is every the rotating speed of 2 seconds calculating preliminary crushers.When the rotating speed decline that this PLC calculated, then judge disintegrating machine generation stall, PLC control relay KA action: normally closed contact disconnects, and disintegrating machine is shut down; Simultaneously, the normal opened contact closure, siren sends alarm signal, reminds the timely handling failure of operating personnel.
