Description

Continous way ion-exchanger control device

The utility model relates to a kind of control device of floating bed type continous way ion exchange water treatment equipment.

In automatic switchover continous way ion-exchange unit, need allow the rotary valve assembly rotate a fixing angle on time, finish each exchange column exchange operating mode, in continuous rotary course, each exchange column is finished in the switching of producing between water, pine bed, regeneration, little cleaning, great purge order and is respectively moved once, finish circulation, work so again and again, thus the process of realization continous way ion-exchange.At present, for the control of the rotary valve assembly anglec of rotation, be to adopt the complex component of a series of mutual transmissions such as traditional motor, belt pulley, leading screw, screw, moving bar, shift fork to be equipped with the part electrical equipment to control and realize its automatic switchover purpose.The method that this control is switched because reciprocating existence is subjected to the influence of its transmission inertia, causes the offside and rotary valve endoporus dislocation of moving bar, also causes the damage of drive disk assembly simultaneously easily.Though some producers have also taked the offside measure of various controls to some extent, fail to tackle the problem at its root always.

The purpose of this utility model provides a kind of continous way ion-exchanger control device, has save reciprocating motion, and inertia is little, and is simple in structure.

The purpose of this utility model realizes as follows: this continous way ion-exchanger control device relates to rotary valve assembly, motor and valve shaft, ratchet is installed on valve shaft, on the ring flange of rotary valve assembly, microswitch is housed, the swing arm roller of microswitch directly upwards contacts with ratchet, motor is fixed on the ring flange with support, and motor is connected with valve shaft power.

The power connected mode of motor and valve shaft is: motor is equipped with pinion in a side of valve shaft on motor shaft, gear wheel is housed on valve shaft, and two gears are meshed.The power of motor is connected to valve shaft through primary gear speed reducing like this.

The another kind of power connected mode of motor and valve shaft is: motor is above valve shaft, and motor shaft and valve shaft are connected through shaft coupling is coaxial.

Used motor is the counterseal slowspeed machine.

The advantage that the utility model had is: the anglec of rotation that cooperates electric circuit control rotary valve with ratchet and microswitch, fundamentally solved the offside problem of appearance in original control system course of work, thereby the product water quality and the flow of interchanger have been guaranteed, reliable operation, prolong service life.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the front view of a kind of structure of the utility model continous way ion-exchanger control device.

Fig. 2 is the vertical view of continous way ion-exchanger control device among Fig. 1.

Fig. 3 is the front view of the another kind of structure of the utility model continous way ion-exchanger control device.

Fig. 4 is the control circuit figure of the utility model continous way ion-exchanger control device.

With reference to Fig. 1, Fig. 2, a kind of embodiment of this continous way ion-exchanger control device: ratchet 7 is installed on valve shaft 10, on the ring flange 2 of rotary valve assembly 1, microswitch 8 is housed, the swing arm roller of microswitch 8 upwards contacts with ratchet 7 footpaths, and motor 6 is the counterseal slowspeed machine, is fixed on the ring flange 2 with support 3, motor 6 is in a side of valve shaft 10, pinion 4 is housed on motor shaft 9, gear wheel 5, two gears is housed on valve shaft 10 is meshed.When the roller that rotates to microswitch 8 when ratchet 7 enters the V-type groove of ratchet 7, microswitch 8 contacts disconnect, motor 6 outages stop operating, other all drive disk assemblies stall immediately, both rotary spool was just finished a fixing anglec of rotation, realize an exchange operating mode handoff procedure, ratchet 7 circumference are provided with the ratchet of ten equal equal angles, each ratchet all has a V-type groove, on behalf of an exchange operating mode, each ratchet action once switch and is finished, and ratchet 7 rotates a circle, then represent two switching and each post exchange operating modes between exchange column: produce water, the pine bed, regeneration, little cleaning, each action of switching between the great purge order is once finished an exchange cycles.Go round and begin again like this and realize the automatic control of continous way interchanger.In addition, rotary valve assembly 1 is provided with former water water inlet pipe 13, magnetic valve 12 and Pressure gauge 11.Former water enters in the rotary valve assembly 1 through former water water inlet pipe 13 and magnetic valve 12; the Push And Release of magnetic valve 12 is synchronous with shutdown with the start of complete equipment; Pressure gauge 11 is used for the height of indicating equipment intake pressure, so that control and guarantee the reliable and economical operation of device security.

With reference to Fig. 3, the another kind of embodiment of this continous way ion-exchanger control device: in this embodiment, motor 6 is above valve shaft 10, motor shaft 9 and valve shaft 10 are through 14 coaxial connections of shaft coupling, two travelling gears between motor 6 and the valve shaft 10 have been omitted, other parts are identical with preceding embodiment, repeat no more.

With reference to Fig. 4, connect power supply, the normally closed closure of microswitch SQ, time relay KT must establish the beginning timing by cable, fluid level controller SL gets electricly simultaneously, during less than a high position, fluid level controller SL is in the normally open position as water level, auxiliary reclay KA not electric attonity.Magnetic valve YV gets electric opening, and produces water, indicator lamp HL ₂Bright, water is produced in indication.Water level is after a high position, and probe received signal, signal are input to fluid level controller SL, and normal switching of fluid level controller SL closed, and auxiliary reclay KA coil gets electric, and magnetic valve YV dead electricity is closed, and produces water indicator lamp HL ₂Go out.Auxiliary reclay KA normally opened contact closure, indicator lamp HL ₁Bright, indication water is full; Simultaneously, auxiliary reclay KA relay K turn-on time T halt signal makes its time out, and entire equipment all is in halted state, waits for the decline of water level.Water level drops to after the meta, and water level controller SL probe signal interrupts, and water level controller SL often leaves dead electricity, auxiliary reclay KA coil losing electricity, and magnetic valve YV opens, and produces water indicator lamp HL ₂Bright, time relay KT halt signal interrupts, and equipment is in normal operating conditions.During the equipment operate as normal, the normally closed closure of microswitch SQ, time relay KT gets electric timing, time relay KT action behind the setting-up time, the normally opened contact closure, motor M is rotated, and drives ratchet 7 and rotates.Ratchet 7 itself has station, when station arrives microswitch SQ, and the normally closed disconnection of microswitch SQ, the normal switching closed.Time relay KT dead electricity.Motor M is rotated further under the power supply of microswitch SQ, and after station surpassed microswitch SQ, microswitch SQ often cut-off out, the motor M stall, and the normally closed closure of microswitch SQ, it is electric that time relay KT is got, reclocking.Button SM is manual Pause key, presses back and self-locking, and light emitting diode is bright, is designated as halt signal.The middle and high water level signal of another group button SB contacting.The normal switching of water level controller SL closed, and auxiliary reclay KA gets electric, is time-out this moment.
