Abstract

The utility model provides a quartz electron swap-time controller which is controlled by a coke oven or other devices. An ordinary high precision household quartz electronic clock is adopted as a timer, a contact K composed of a gear 4 used for controlling the output of time and which is arranged on a minute hand time traveling gear shaft 3, a movable shell splinter contact 1 and a static shell splinter contact 2 is additionally arranged in the quartz clock, a delay control circuit composed of a time relay ZJ<1> connected with the contact K, a delay relay SJ and a middle operational relay ZJ<2> is used to control the reverse control device of the coke oven. The quartz electron swap-time controller has the advantages of simple structure, high precision of time control and small workload of maintenance, and the cost of the quartz electron swap-time controller is only one tenths of a time program controller.

Description

Quartzcrystal swap-time controller

The utility model belongs to quartz electronic swap time of controller, controls quartz electronic swap time of the controller of coke oven heating commutating period especially.

As everyone knows, the coke oven heating needs commutation in per 20～30 minutes once, and the control of commutating period needs accurately and reliably.At present capacity coke oven generally all adopts the electronic time director, perhaps program timer etc., and the coke oven that also has adopts mechanical clock as time controller.These controllers all have its weak point: it is bigger that mechanical pendulum clock is generally walked time error, and mechanical part weares and teares easily; Inaccurate when electronics device, part cause away because of influenced by mains frequency, thus coke oven commutation control influenced.

The purpose of this utility model provides a kind of mains frequency that is not subjected to be influenced, and does not have the time controller that changes of mechanical wear.

According to the utility model, adopt the bare bones of quartz analog clock as time controller, set up a contact in quartz analog clock inside, draw signal reference time, this contact and timing relay circuit join, and signal removes to control the exchange control gear of coke oven or other user's controlled systems through this delay circuit.

According to the utility model, the interior contacts of quartz analog clock by be contained in minute hand when walking the control time output gear on the gear shaft and the spring plate and the quiet shell fragment that are associated formed.

According to the utility model, the control time output gear rotates with the minute hand shaft of quartz analog clock, during to the stipulated time, this gear touches spring plate, pushes this spring plate to quiet shell fragment, forms the closed-loop path, control signal starts exchange control device through the time breaker delay circuit.

According to controller quartz electronic swap time of the present utility model, swap time is accurate, and is simple in structure, and maintenance load is few, and is cheap, uses reliably, can be widely used in coke oven or other times controller.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is the utility model crystal clock interior contacts synoptic diagram.

As shown in Figure 1, the utility model is by crystal clock interior contacts K, the time relay ZJ that is connected of contact K therewith ₁With timing relay SJ, controlled loop intermediary operation relay ZJ ₂Interconnect and form.When clock inner contact K is closed, DC relay ZJ ₁Electric, contact action makes time relay sj get electric and gets ready for opening of its normally closed time-delay contact, meanwhile, time relay sj contact and DC relay ZJ ₁Contact is connected the loop, makes intermediary operation relay ZJ ₂Coil gets electric and starts, the operation reversing control system.When setting time arrives, the automatic opening operation of timing relay SJ contact loop is for preparing next time.

As shown in Figure 2, crystal clock inner contact K by be contained in minute hand when walking control time output gear (action gear) 4, spring plate contact 1, the quiet shell fragment contact 2 on the gear shaft 3 formed, the mounting means of this contact K is, when control time output gear 4 from the below during near spring plate contact 1, crown can touch spring plate contact 1 and it is lifted after touch quiet shell fragment contact 2, the crown spring plate contact 2 that can slip away then.Commutation can be set at 1～59 second the control time, the number of teeth and the commutation control time of control time output gear are inversely proportional to.For example, the commutation control time is 30 minutes, and the number of teeth equals 2, and the commutation control time is 20 minutes, and the number of teeth equals 3, and the rest may be inferred.

As shown in Figure 2, the rotation of gear shaft 3 when walking along with minute hand, dress control time output gear 4 thereon also rotates thereupon, when turning to the stipulated time, the crown of gear touches spring plate contact 1 and it is lifted, and makes it to join with quiet shell fragment contact 2 and constitute path.The output control signal starts time-delay pilot relay loop.

Crystal clock of the present utility model can adopt the family expenses crystal clock of common accurate timing; Time relay ZJ ₁Be DC relay, can select for use by the operating voltage grade; Timing relay SJ is SJ ₇The series time relay.

The utility model is simple in structure, and installation, easy to use, with low cost only is 1/tens of program timer, and economical and practical, effect is splendid.

Claims

1, a kind of quartz electronic swap time of controller of being made up of quartz analog clock and relay is characterized in that a contact K that this controller set up by quartz analog clock inside, the time relay ZJ that is connected of contact K therewith ₁With timing relay SJ, controlled loop intermediary operation relay ZJ ₂Interconnect and form, said contact K by be contained in minute hand when walking control time output gear 4, spring plate contact 1, the quiet shell fragment contact 2 on the gear shaft 3 formed, the mounting means of this contact K is, when control time output gear 4 from the below during near spring plate contact 1, crown can touch spring plate 1 and it is lifted after touch quiet shell fragment contact 2, the crown shell fragment contact 2 that can slip away then.
