Description
Technical field
The utility model relates to the detection protective device, more specifically, is a kind of online detection protective device for the sintering trommel mixer.
Background technology
Sintering trommel mixer (or claim batch mixer) is one of visual plant in the agglomerates of sintered pellets system, and it can be used for raw material and mixes, granulates, rolls the multiple uses such as coal, to satisfy in the follow-up flow process sintering machine to the requirement of raw material.As shown in Figure 1, the drive mechanism of trommel mixer 1 mainly is gear drive, its part mainly is comprised of main motor 2, hard-tooth surface speed reducer 3 and pinion assembling, bull gear, transmission base etc., supports and adopts support roller, wheel to be with two grades of supports, and adopt shelves wheel fixed displacement.Normal in service because mixer inertia is large at equipment, starting current is large, therefore very easily cause the impact to each gear and axle in the reductor 3, in addition, oil leakage phenomenon also is most common failure in the gearbox drive system, the leakage of oil meeting affects gear, the lubricant effect of the casees such as bearing, so that friction aggravation between each kinematic pair spare and accessory parts, in case trommel mixer drive mechanism reductor 3 breaks down, during such as the fast axle fracture of reductor or fluid coupling inefficacy, and its main motor 2 is also running well, and this moment, trommel mixer 1 was stopped transport, because existing trommel mixer 1 is take main motor normal operation signal as benchmark at the signal of control system running, therefore according to this signal, if main motor 2 operations illustrate that trommel mixer 1 also moves; Main motor 2 stops, and illustrates that trommel mixer 1 also stops.As mentioned above, in case master's motor 2 is also running well when running into the inefficacy of reductor 3 fast axle fractures or fluid coupling, trommel mixer 1 has been stopped transport, but control system can not think that trommel mixer 1 stopped transport, enter in the trommel mixer 1 but still control the upstream material, can cause like this accident of serious buildup, flash in the mixer to occur.
The utility model content
The purpose of this utility model is to solve the problems referred to above that the sintering trommel mixer occurs in running, thereby a kind of online detection protective device that is used for the sintering trommel mixer of innovation is provided.
Online detection protective device for the sintering trommel mixer of the present utility model; can be used for providing online detection protection to the normal operation of sintering trommel mixer; described sintering trommel mixer is by the control of control loop; under main motor-driven, move; should detect online two sensing chips that protective device comprises the input side inboard that is arranged on described sintering trommel mixer; approach switch for detection of described sensing chip rotation; the signal processor that is connected with described approach switch and the power transfer relay that is connected with described signal processor, described power transfer relay comprises an output contact that is serially connected in the described control loop.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, to composition of the present utility model and operation principle and detailed description.
As shown in Figure 2; online detection protective device for the sintering trommel mixer of the present utility model; can provide online detection protection to sintering trommel mixer 1 (referring to Fig. 1); sintering trommel mixer 1 passes through control loop (referring to Fig. 4; 5) control; operation under main motor 5 drives; particularly; in conjunction with Fig. 2; 3; online detection protective device for the sintering trommel mixer of the present utility model comprises that the sensing chip 10 of the input side inboard that is arranged on described sintering trommel mixer 1 (comprises two sensing chips 11; 12); for detection of sensing chip 11; 12 approach switchs 20 that rotate; the signal processor 30 that is connected with approach switch 20 and the power transfer relay 40 that is connected with signal processor 30; referring to Fig. 5, power transfer relay 40 comprises an output contact KA1_1 who is serially connected in the described control loop 6.
Particularly, shown in Fig. 2,3, sensing chip 10 comprises the sensing chip 11,12 that is formed by two steel discs, and it is inboard to be welded on respectively trommel mixer 1 input side.Approach switch 20 is installed on the frame on next door as sensor, and the model of approach switch 20 can be selected Bil5-cp40-vp4x 2/s34 type approach switch, also can select other suitable types.The inductive head of approach switch 20 should be near sensing chip 11,12, and the spacing between itself and the sensing chip preferably remains on about 12mm.
Shown in Fig. 4,5, be respectively the schematic diagram of major loop and control loop in the electric part of trommel mixer 1.In conjunction with Fig. 4,5, in control loop 6, include contactor coil KM, switch S F, indicator lamp HG, the auxiliary contact KM_1 of contactor coil KM and power supply signal N, in major loop 4, three phase mains L1, L2, L3 are serially connected with respectively auxiliary contact KM_2, KM_3, the KM_4 of contactor coil KM.The output contact KA1_1 of power transfer relay 40 is serially connected in the control loop 6.
When the input side of trommel mixer 1 rotates, sensing chip 11,12 is with its rotation, approach switch 20 just can monitor a pulse signal 1TB, and it is flowed to signal processor 30, whether signal processor 30 detects this pulse signal and switches between high level and low level, if exist high-low level to switch, illustrate that then trommel mixer 1 works well, signal processor 30 sends closure signal to power transfer relay 40, make its output contact KA1_1 remain on closure state, control loop 6 and major loop 4 normally power on, and main motor 5 normally moves.And if do not have switching between the high-low level, illustrating then that trommel mixer 1 is in operation breaks down, signal processor 30 sends cut-off signal to power transfer relay 40, its output contact KA1_1 disconnects, and then the control loop outage, contactor coil KM dead electricity, its a plurality of auxiliary contact KM_1, KM_2, KM_3, KM_4 disconnect, main motor 5 dead electricity, thus make trommel mixer 1 out of service.
In sum; online detection protective device for the sintering trommel mixer of the present utility model; by the detection that the trommel mixer speed of service is changed; guaranteed the run-in synchronism of trommel mixer system and main motor; avoided after trommel mixer shuts down, the control system still situation of operation as usual occurs.Thereby guaranteed the safe operation of whole system, avoided the hidden danger that exists in the prior art.
