Abstract
The utility model discloses an excess loading protector of impeller feeder, including driving motor, driving motor links the below impeller, and the proximity switch support is installed to the impeller below on the feeder organism, install proximity switch on the proximity switch support, and proximity switch's return circuit is inserted in the feeder control box. And signal acquisition when stopping rotatory to the impeller through proximity switch in time conveys the control box with the impeller situation, is blocked timely stop driving motor when stopping at the impeller, has in time protected motor and speed reducer, avoids " three bolds " to damage speed reducer and driving motor.
Description
Technical field
The utility model relates to power plant coal feeder protection system device, particularly relates to a kind of overload protection device of paddle coal feeder.
Background technology
Impeller Coal Reclaimer Machine in Thermal Power Plant is the main coal supply equipment of coal handling system, because thermal powerplant uses faulty coal, in coal, foreign material are many, especially " three bulks " is more, particularly ratchel, big iron etc., when paddle coal feeder runs, feeder vane rotary touches " three bulks ", impeller is transshipped instantaneously, but electrical motor can not stop immediately, very easily damage paddle coal feeder reductor and drive motor.
Utility model content
In order to solve the problems of the technologies described above, the utility model aims to provide a kind of overload protection device of paddle coal feeder.
The utility model is achieved by following technical solution:
A kind of overload protection device of paddle coal feeder; comprise drive motor, below drive motor, link impeller, below impeller, on feeder body, proximity switch support is installed; proximity switch support is provided with proximity switch, in the loop access feeder control box of proximity switch.
Described proximity switch is connected with the control circuit of drive motor.
The beneficial effects of the utility model are:
Compared with prior art; the overload protection device of a kind of paddle coal feeder that the utility model provides is by the acquisition of signal of proximity switch to vane rotary and when stopping; in time impeller situation is sent to control box; drive motor is stopped in time when impeller is stuck and stops; protect motor and reductor in time, avoid " three bulks " to damage reductor and drive motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-drive motor, 2-impeller, 3-proximity switch, 4-proximity switch support, 5-feeder body, 6-control box.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As shown in the figure; the overload protection device of a kind of paddle coal feeder that the utility model provides; comprise drive motor 1; impeller 2 is linked below drive motor; on feeder body 5, proximity switch support 4 is installed below impeller 2; proximity switch support 4 is provided with proximity switch 3, in the loop access feeder control box 6 of proximity switch 3.When impeller 2 rotates, proximity switch 3 imports the signal parameter of variation into control box 6, imports fixed signal into when impeller 2 is stuck and stops, and makes control box 6 control drive motor 1 in time and stops.
In order to motor can stop in time.Described proximity switch 3 is connected with the control circuit of drive motor 1.
Claims (2)
