Abstract
The utility model discloses an air-lock valve timing cycle control device comprising a starting contactor KM and a starting relay KA; a time relay KT is arranged in parallel with the starting contactor KM and is provided with a normally close control contact KT1; the normally close control contact KT1 of the time relay KT is arranged in a voltage loop controlling the power source of the starting contactor KM; and a control contact KA1 of the starting relay KA is arranged in a voltage loop controlling power of the starting contactor KM and the time relay KT. Compared with the prior art, the work of the air-lock valve is controlled in an intermittent timing cycle control manner; so the air-lock valve timing cycle control device can effectively reduce power consumption, minimize parts wearing, thereby reducing equipment failure rate and operation cost.
Description
Technical field
The utility model relates to a kind of wind stopping device timing cycle control device.
Background technology
Wind stopping device has another name called star-like discharger, unloading valve, Blowing stopper, rotary feeder, common structure is comprised of impeller of rotor, housing, seal, decelerator and the motor etc. with several pieces blades, because it is applicable to granular material and granulated material, therefore using on raymond mill, also be widely used on the production equipment of the industries such as environmental protection, metallurgy, chemical industry, grain, food.
But wind stopping device is as a kind of plant equipment commonly used, as in raymond mill, wind stopping device generally is arranged on the grader cylindrical shell bottom of raymond mill, adopt threephase motor as power, currently used traditional start-stop control circuit is controlled, and wind stopping device is in operating condition always, the one, energy consumption is higher, the 2nd,, component wear is serious, and equipment failure rate is corresponding increasing also.
And in actual motion, generally according to material blanking velocity situation, do not need wind stopping device to turn round always, simultaneously, the ash bucket that is arranged on above wind stopping device can be stored a certain amount of material.Therefore wind stopping device can be taked service intermittent according to actual conditions, treats to restart work after having a certain amount of material in ash bucket, can quit work afterwards, can avoid unnecessary wear and tear in machines, can also reduce energy consumption simultaneously.
So, a kind ofly can reduce energy consumption, alleviate component wear serious, and then the wind stopping device timing cycle control device that reduces equipment failure rate just arises at the historic moment.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can reduces energy consumption, alleviates component wear serious, and then reduces the wind stopping device timing cycle control device of equipment failure rate.
the purpose of this utility model realizes by following structure: comprise starting contactor KM and starting relay KA, starting contactor KM controls the on-off of wind stopping device motor M power supply by controlling contact KM1, starting relay KA controls the power supply of starting contactor KM by contact KA2, its improvement is: be arranged in parallel free relay K T with starting contactor KM, this time relay KT is provided with normally closed control contact KT1, and the normally closed control contact KT1 of time relay KT is arranged in the voltage circuit of the power supply of controlling starting contactor KM, the control contact KA1 of starting relay KA is arranged in the voltage circuit of the power supply of controlling starting contactor KM and time relay KT.
As improvement, the utility model is provided with thermal relay FR, and this thermal relay FR is provided with normally-closed contact FR1, and this normally-closed contact FR1 is arranged in the voltage circuit of power supply of contactor KM.
Compared with prior art, the utility model can effectively reduce energy consumption, and alleviate component wear by the work of intermittent timed loop control wind stopping device, and then reduces equipment failure rate and operating cost.
Description of drawings
Fig. 1 is the circuit diagram of the utility model embodiment 1.
Shown in figure: KA is starting relay, KM is that starting contactor is, KT is the time relay, FR is thermal relay, and KA1, KA2, KM1, KT1 and FR are respectively the control contact of starting relay KA, starting contactor KM, time relay KT and thermal relay FR, and M is the wind stopping device motor, SB1, SB2 are hand switch, QF1 is circuit breaker, and A, B, C are binding post, and HL1, HL2 are indicator light.
Embodiment
embodiment 1: with reference to Fig. 1, be the utility model embodiment 1 circuit diagram, comprise starting contactor KM, starting relay KA, starting relay KA is by hand switch SB1, SB2 and control contact KA1 consist of a self-locking control circuit, starting contactor KM controls the on-off of wind stopping device motor M power supply by controlling contact KM1, starting relay KA controls the power supply of starting contactor KM by contact KA1, be arranged in parallel free relay K T with starting contactor KM, this time relay KT is provided with normally closed control contact KT1, and the normally closed control contact KT1 of time relay KT is arranged in the voltage circuit of the power supply of controlling starting contactor KM, the control contact KA1 of starting relay KA is arranged in the voltage circuit of the power supply of controlling starting contactor KM and time relay KT, be provided with simultaneously thermal relay FR, this thermal relay FR is provided with normally-closed contact FR1, and this normally-closed contact FR1 is arranged in the voltage circuit of power supply of contactor KM, the thermal sensor of thermal relay FR is arranged on wind stopping device motor M body, operating temperature with induction wind stopping device motor M.
In actual use, can set in advance the control time of time relay KT, such as, two periods of setup times relay K T, its set point is respectively: T1=2 minute, and T2=4 minute, perhaps set point is respectively: T1=3 minute, T2=5 minute, the set point of certain two periods also can be identical, as T1, T2 be 4 minutes, 3 minutes or 5 minutes.
Whole control procedure is as follows: the set point of time relay KT is respectively: T1=2 minute, T2=4 minute, after pressing the button SB1, starting relay KA gets electric its normally opened contact KA1 adhesive self-locking, run indicator HL1 is bright in system, make starting contactor KM and time relay KT get electric after the normally opened contact KA2 of starting relay KA adhesive simultaneously, the wind stopping device motor is started working, between relay K T first paragraph time T 1 beginning timing, after 2 minutes, the contact KT1 of time relay KT moves first, make starting contactor KM dead electricity, the wind stopping device motor stops operating.The meanwhile second segment time T 2 beginning timing of time relay KT, after 4 minutes, the contact KT1 of time relay KT moves again, starting contactor KM is got electric, and the wind stopping device motor begins again to rotate, and so repeatedly, makes wind stopping device be in the service intermittent state.Whole system quits work after pressing the button SB2.
