Abstract

The utility model relates to a salt solution concentration sensor for water-softener, which is used for detecting concentration of salt solution and coordinated with the controller of water-softener. The sensor comprises a rod body that is fixed in the salt box by a fixture and provided with a brine float and a freshwater float; wherein a magnetic ring is fixed on the brine float and the freshwater float, a check ring is also fixed on the rod body at the lower end of the brine float and the freshwater float. The prior water-softener is unable to detect concentration of salt solution without the sensor, thus is manipulated only by experience and feeling, which directly influences on soften performance of hard water due to concentration instability of salt solution, even worse results in invalidation of ion exchange resin regeneration. Now the salt box is equipped with the sensor, which can detect concentration of salt solution in real time and remind user adding salt to the salt box through light and sound signal after the switch of controller is put through, thus salt content, soften performance and quality are guaranteed, and work efficiency is improved as well.

Description

Water softening device saline solution concentration sensor

Technical field

The utility model relates to a kind of saline solution concentration detector, particularly a kind of water softening device saline solution concentration sensor.

Background technology

Raising along with people's living standard, the reinforcement of environmental consciousness, for healthy people more and more higher to the water quality requirement of potable water, domestic water, especially in hard water areas,, can in watering equipment, produce incrustation scale as calcium ion, the magnesium ion that wherein contains because of containing each heavy metal species and impurity in the water, easily stop up and use drainage facility, influence people's normal life and work, need to handle entering with the former water of drainage facility for this reason, the method that generally adopts mostly is the use water softening device at present.

Patent No. CN99253772.X " family expenses water softening device ", patent No. CN02205183.X " the integrated small water softening device ", a kind of water softening device of handling hard water just is provided, promptly adopt the ion exchange resin softening of water, but after water softening device work a period of time, because the sodion in the resin is fewer and feweri, finally can be by replacements such as calcium ion, magnesium ions, the hardness of the resin cation state that reaches capacity just can not play in the planar water impurity.At this moment also need carry out regeneration of resin, promptly need in the auxiliary salt cellar of water softening device with salt, make it produce regenerative response, displace calcium, magnesium plasma with sodion, sodion is adsorbed on the resin, and hardness ions and salt solution are discharged from blow-off pipe together, resin just recovers exchange capacity, water softening device enters duty again, so constantly recycles, and reaches the purpose of softening of water.

The use of existing Automatic Control valve, improved the intelligent degree of water softening device greatly, but along with the water softening device exchange resin need be inhaled salt regeneration, then to consume a large amount of salt, to cause the reduction of saline solution concentration because of the minimizing of salt, and do not mention the detection problem of saline solution concentration in the above-mentioned various water softening devices, because of not having measurement, pick-up unit, only grasp, control with individual's experience, to such an extent as to also fail when not having enough salt in the salt case effectively to remind, show, cause ion exchange resin regeneration to lose efficacy, influence the operate as normal and the bating effect of water softening device.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of water softening device saline solution concentration sensor is provided, be installed in the salt case of water softening device, be connected supporting use during regeneration with controller, at any time detect the concentration of saline solution in the salt case, and remind the user to the salt case with salt, thereby guarantee the bating effect of water softening device.

The technical scheme that the utility model addresses the above problem employing is: water softening device saline solution concentration sensor, by connecting saline water float, fresh water float on the body of rod, the body of rod is fixedly mounted in the salt case with securing member to be formed, also be fixed with magnet ring on described saline water float, the fresh water float, also be fixed with spacing collar on the body of rod at saline water float, place, fresh water float lower surface.

Compared with prior art, advantage of the present utility model is: no saline solution concentration detection apparatus on the former water softening device, the main experience that relies on the user, feel to place the salt operation, many, can't detect less, so concentration instability, directly influence bating effect, even also caused ion exchange resin regeneration to lose efficacy.Increase the dress saline water float in the salt case of water softening device now, the saline solution concentration sensor that fresh water float constitutes, by float transfixion in fresh water or low concentration salt solution, cut-off switch also is judged to be light saline solution, make the controller supporting do the acousto-optic alarm with it, show, the prompting user need be with salt, if float is in saturated brine the time, float can upwards float, utilize the switch on the magnet steel connection controller on the float, finish the measurement of saline solution concentration by controller, make all to obtain monitoring in the whole regenerative process, guarantee the content of salt, effectively guarantee bating effect, softening quality reduces the softening time again, increases work efficiency.

Embodiment

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

In saline water float 3, the fresh water float 6 lower end intermediate groove, tight embedding is by magnet ring 3-1, the 6-1 of magnet steel making respectively.Spacing collar is the jump ring 7 that has opening.

Saline water float 3, side dress fixed mount 4, fresh water float 6 are enclosed within on the position, upper, middle and lower of the body of rod 1 successively, and respectively in the annular groove on the lower surface body of rod 1 of saline water float 3, side dress fixed mount 4, fresh water float 6, fixedly jump ring 7 is made spacing usefulness, as shown in Figure 1.If sensor is vertically installed, can cancel side dress fixed mount 4, as shown in Figure 2.

Screw off nut 2 during use, make the top of the body of rod 1 pass through hole on the salt case inner bottom plating, be tightened on base plate (figure draws) with nut 2 again, or be fixed on (figure is picture) on the base plate with side dress fixed mount 4 usefulness nuts 2, pad 5.

For avoiding in the salt case when anhydrous the sensor mistake to survey, the special fresh water float 6 that increases uses as there being water to detect.If when in the salt case water being arranged, fresh water float 6 come-up is connected the switch on the controller, demonstrates and has detected water state, and is opposite when anhydrous, and fresh water float 6 is because action of gravity is returned to original position, position as shown in Figure 1 and Figure 2, and switch disconnects, and demonstrates anhydrous state.

Having under the situation of water, if the salt in the salt case is enough, make brine concentration near saturated, this moment saline water float 3, magnet ring 3-1 come-up is connected the switch on the controller, detect dense salt liquid status, but along with the regeneration of water softening device ion exchange resin suction salt needs to consume a large amount of salt, because the minimizing of salt will cause saline solution concentration slowly to reduce, when the saline solution density loss to the buoyancy of saline water float 3, during less than the weight of saline water float itself, saline water float moves down and gets back to initial position under the effect of self gravitation, switch disconnects, display switch on then supporting with it controller is connected, and just has acousto-optic to show, reminds the user need be with salt.
