Description

Backwashing device of water softener

Technical Field

The utility model relates to a water softener field especially relates to a backwash device of water softener.

Background

The water softener mainly removes calcium and magnesium ions in water through ion exchange resin to reduce the hardness of water. Compared with tap water, the soft water has very obvious taste and hand feeling. After the soft water is used, scales are not generated in the water cup, the teapot, the bathtub and the water bucket, and the water cup, the teapot, the bathtub and the water bucket are easier to clean. The water pipe in the house can not scale, the service life of the water heater is longer, and the hot water flow is smaller and smaller because of long service time. The soft water can reduce the use amount of detergent, soap and other washing articles, greatly reduce the maintenance cost of water pipes, prolong the service life of clothes by 32% compared with the service life of clothes washed in hard water, prevent clothes from becoming full of spring, make white shirts whiter, make blue shirts bluer and make the clothes brighter.

The main filter material of the existing water softener is softening resin which is used for adsorbing calcium and magnesium ions in water. When the exchange capacity of the softening resin is saturated, 5-8% of saline water is needed to carry out backwashing on the softening resin, calcium and magnesium ions adsorbed on the resin are exchanged by sodium ions, and the calcium and magnesium ions can be exchanged again by the softening resin to soften the water quality. The backwashing device of the existing water softener switches a water path through a combined valve head to suck saline water into a resin bin, washes saturated resin and completes the backwashing process. The structure and the manufacturing process of the combined valve head are complex, so that the size and the price of the valve head are large, and the price of the whole water softener is increased. Therefore, a new backwashing device is needed to reduce the volume of the water softener and reduce the salt amount for backwashing.

Disclosure of Invention

The utility model aims to solve the technical problem that a backwash device of water softener is provided, simple structure, the power of backwash is switched for the water pump from running water pressure and is provided pressure, reduces the cost of this device, has reduced the volume of water softener, for the miniaturization of water softener, and the basis is done in the automation, has great help to the economic nature of water softener and the salt volume that reduces the backwash.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a backwash device of water softener, including storing up the salt storehouse, the inside position that is close to the bottom of storing up the salt storehouse install the salt baffle with store up the salt storehouse and separate for from top to bottom and store up salt chamber and water storage chamber, the lateral wall in storage salt storehouse on install the water pump, the end of intaking of water pump be linked together through first connecting pipe and water storage chamber, the play water end of water pump links to each other through second connecting pipe and a plurality of resin filter storehouse, the external inlet tube of lateral wall in water storage chamber.

Furthermore, one end of the second connecting pipe is connected with the flow distribution plate, and the resin filtering bin is connected with the flow distribution plate.

Furthermore, a one-way valve is installed on the second connecting pipe.

Has the advantages that: the utility model relates to a backwash device of water softener, moreover, the steam generator is simple in structure, the power of backwash is switched from running water pressure and is provided pressure for the water pump, will just wash and keep apart with two way water routes of backwash, simplify the valve head water route, reduce whole backwash device total volume, provide probably for the salt solution that decides concentration simultaneously, reduce the cost of this device, reduced the volume of water softener, for the miniaturization of water softener, the basis is done in the automation, there is great help to the economic nature of water softener and reduction salt volume for the backwash.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

As shown in figure 1, the embodiment of the utility model relates to a backwashing device of water softener, including storing up salt storehouse 1, the inside position that is close to the bottom of storing up salt storehouse 1 install salt baffle 4 and separate from storing up salt storehouse 1 from top to bottom for storing up salt chamber 3 and water storage chamber 2, the lateral wall of storing up salt storehouse 1 on install water pump 5, water pump 5's the end of intaking be linked together through first connecting pipe 6 and water storage chamber 2, water pump 5's the end of exhalant is crossed second connecting pipe 7 and is filtered the storehouse 9 with a plurality of resin and is linked to each other, the external inlet tube 8 of lateral wall of water storage chamber 2.

One end of the second connecting pipe 7 is connected with the flow distribution plate 10, and the resin filtering bin 9 is connected with the flow distribution plate 10.

And a check valve is arranged on the second connecting pipe 7 to prevent the reverse flow of the saline water.

As an embodiment of the present invention:

a normal washing state: after entering from the water inlet valve of the water softener, the water is evenly distributed to the resin filtering bin 9, and the water is guided into the bottom of the resin filtering bin 3 and flows through the resin from bottom to top to seep out, so that the exchange of calcium and magnesium ions is completed.

And (3) backwashing state: before the resin is backwashed, the water level of the salt storage bin 1 is always kept at the lowest water level second water level sensor, at the moment, softened salt is not completely immersed, only a small part of softened salt is soaked in water, and the salt water in the bin is in a saturated state. After the device is started and reversed, water is injected into the salt storage bin 1 until the water level reaches the position of the first water level sensor, water inflow is stopped, and the concentration of mixed salt water is reduced;

as the solid salt begins to dissolve, the brine density begins to increase from small to large. The density of the float is 1.05g/cm3, when the density of the saline is higher than 1.05g/cm³When the floater floats upwards and reaches the height which can be sensed by the sensor, the water pump 5 starts to work, the salt water pumped from the salt storage bin 1 is evenly distributed to the resin filtering bin 9 through the one-way valve, the water is guided into the bottom of the resin filtering bin 9 to seep out and flows through the resin from bottom to top, and the reverse exchange of calcium and magnesium ions is completed, namely the so-called resin backwashing.

When the water pump 5 pumps the salt water to the position of the second water level sensor, the water pump 5 stops working and enters the circulation of injecting fresh water, dissolving salt and discharging salt water again until the set backwashing flow is reached. When the total amount of the brine pumped by the water pump 5 exceeds the set value and the water level returns to the second water level sensor, the device enters a forward washing state for 5 minutes, and the brine in the resin filter bin 9 is washed.

The utility model discloses simple structure, the power of backwash is switched from running water pressure and is provided pressure for the water pump, will just wash and keep apart with two way water routes of backwash, simplifies the valve head water route, reduces whole backwash device total volume, provides probably for the definite concentration goes out salt water simultaneously, reduces the cost of this device, has reduced the volume of water softener, for the miniaturization of water softener, and the basis is done in the automation, has great help to the economic nature of water softener and reduction salt volume for the backwash.
