Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soft water production equipment, in particular to an automatic salt adding device for a soft water system. Background Art
[0002] Water softening equipment operates on the principle that ion exchange resin (usually sodium ions) is installed within the device. Ions on the resin (usually sodium ions) exchange with calcium and magnesium ions in the water, thereby reducing the calcium and magnesium ion content in the water and achieving the desired softening effect. However, over time, the number of ions on the resin decreases, reducing its exchange capacity and softening effectiveness. If ions are not replenished promptly, the resin will remain ineffective and prone to rupture, leading to resin loss and affecting the performance of the water softener.
[0003] In the prior art, salt addition is usually performed manually, but manual operation is labor-intensive and it is impossible to monitor the brine concentration in real time and replenish it in time. Utility Model Content
[0004] The purpose of the utility model is to address the deficiencies of the above-mentioned prior art and to provide an automatic salt adding device for a soft water system, which can automatically perform salt and water adding operations and provide salt water of stable concentration into the soft water system.
[0005] The utility model proposes an automatic salt-adding device for a soft water system, comprising a neutralization tank and a brine tank. A salinity sensor and a first liquid level meter are provided in the neutralization tank. The salinity sensor is used to detect the concentration of brine in the neutralization tank. The first liquid level meter is used to detect the liquid level height in the neutralization tank. A conveyor for conveying salt into the neutralization tank and a water inlet pipe for conveying water into the neutralization tank are provided outside the neutralization tank. The brine tank is connected to the neutralization tank through a conveying pipe, and the brine tank is connected to a soft water system.
[0006] A better technical solution of the utility model is that the neutralization tank is connected to the air source through an air inlet pipe.
[0007] A better technical solution of the utility model is that compressed air is introduced into the bottom of the neutralization tank through the air inlet pipe.
[0008] A better technical solution of the present utility model is that a sewage outlet is provided at the bottom of the neutralization tank.
[0009] A better technical solution of the present invention is as follows: a second liquid level gauge for detecting the liquid level in the brine tank is provided in the brine tank, and a water pump for controlling the flow of brine from the neutralization tank to the brine tank is provided on the delivery pipeline.
[0010] A preferred technical solution of the present invention further includes a control system, which is electrically connected to the second liquid level gauge and the water pump to control the neutralization tank to supply brine into the brine tank.
[0011] A better technical solution of the present invention is that a plurality of brine tanks are provided, and the plurality of brine tanks are arranged in parallel on the delivery pipeline.
[0012] A better technical solution of the present invention is as follows: a water valve is provided on the water inlet pipe, and the control system is electrically connected to the conveyor, the first liquid level meter, the water valve and the salinity sensor to control the amount of salt and water entering the neutralization tank.
[0013] The automatic salt adding device for a soft water system of the utility model has the following beneficial effects:
[0014] 1. It includes a neutralization tank and a brine tank. The neutralization tank sends the prepared brine with standard concentration to the brine tank, which then flows into the soft water system. The brine is pre-mixed in the neutralization tank, which can reduce the brine concentration error and improve the brine replenishment efficiency.
[0015] 2. A salinity sensor is installed in the neutralization tank to monitor the salt water concentration in the neutralization tank. The value detected by the salinity sensor controls the water intake and salt addition, so that the salt water concentration in the neutralization tank meets the use requirements of the soft water system;
[0016] 3. Compressed air is introduced into the neutralization tank through the air inlet pipe. The compressed air enters the bottom of the neutralization tank. The gas moves upward from the bottom of the neutralization tank, causing the liquid in the neutralization tank to tumble, accelerating the dissolution of salt in water. At the same time, the brine is evenly distributed in the neutralization tank, ensuring that the brine concentration is consistent everywhere in the neutralization tank.
[0017] 4. A control system is provided to control the amount of salt added to the neutralization tank, the amount of water inlet, and the amount of brine replenished in the brine tank, so as to replenish brine to the soft water system in a timely manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be arbitrarily combined with each other.
[0022] See also Figure 1 An automatic salt-adding device for a soft water system includes a neutralization tank 10 and a brine tank 70. A conveyor 20 is provided outside the neutralization tank 10 for conveying salt into the neutralization tank 10. A water inlet pipe 30 is provided on the neutralization tank 10, through which water enters the neutralization tank 10. A salinity sensor 12 is provided in the neutralization tank 10 for detecting the concentration of brine in the neutralization tank 10. The brine tank 70 is connected to the neutralization tank 10 through a conveying pipe 80, and the brine tank 70 is connected to the soft water system. After the salt and water are mixed to an appropriate concentration in the neutralization tank 10, they are sent to the brine tank 70, and brine is replenished into the soft water system through the brine tank 70.
[0023] In this embodiment, conveyor 20 is an elevator, and salt is placed on the elevator. The elevator operates to transport the salt to the top of neutralization tank 10, from where it enters the neutralization tank 10. Neutralization tank 10 is provided with a water inlet pipe 30 connected to a water source. Water enters the neutralization tank 10 through the inlet pipe 30, where it merges with the salt to form brine of a certain concentration. Neutralization tank 10 is equipped with a salinity sensor 12 for detecting the brine concentration within the neutralization tank 10. The value detected by salinity sensor 12 is used to control the amount of salt added and the amount of water inlet to ensure that the brine concentration within the neutralization tank 10 meets the brine concentration requirements of the soft water system.
[0024] A first liquid level gauge 11 is provided in the neutralization tank 10 for detecting the liquid level in the neutralization tank 10. The amount of water added can be confirmed by confirming the value of the first liquid level gauge 11, thereby controlling the amount of brine in the neutralization tank 10 to avoid overflowing of the neutralization tank 10 during the preparation of brine.
[0025] An air inlet pipe 40 is provided on the neutralization tank 10. The air inlet pipe 40 is connected to an external gas source for introducing compressed gas into the neutralization tank 10. Specifically, the air inlet pipe 40 is connected to the bottom of the neutralization tank 10 so that after the gas enters the neutralization tank 10, the gas moves upward, and the liquid in the neutralization tank 10 rolls under the drive of the gas, thereby accelerating the dissolution of salt in water. The salt water flows in the neutralization tank 10, and the concentration of the salt water in each place in the neutralization tank 10 remains consistent.
[0026] Taking into account that the neutralization tank 10 is in an open top state during the salt addition process, in order to prevent impurities from entering the neutralization tank 10 during the salt addition process and then being sent from the neutralization tank 10 to the brine tank 70, in the present application, when the delivery pipe 80 is connected to the brine tank 70, the first end of the delivery pipe 80 connected to the neutralization tank 10 is located on the side wall of the neutralization tank 10. Specifically, the connection between the delivery pipe 80 and the side wall of the neutralization tank 10 is located above the bottom of the neutralization tank 10. Preferably, the connection between the delivery pipe 80 and the side wall of the neutralization tank 10 is located about 10 cm above the bottom of the neutralization tank 10. By raising the connection between the delivery pipe 80 and the neutralization tank 10, impurities precipitated in the neutralization tank 10 are prevented from entering the brine tank 70 through the delivery pipe 80, which would cause impurities to enter the soft water system and affect the soft water effect.
[0027] Preferably, a drain port 50 is provided at the bottom of the neutralization tank 10 for draining the liquid in the neutralization tank 10 during cleaning.
[0028] In the present application, brine is prepared in advance in the neutralization tank 10, and the neutralization tank 10 transports the prepared brine of fixed concentration into the brine tank 70, which is then replenished into the soft water system by the brine tank 70, thereby reducing the brine concentration error during the brine preparation process.
[0029] A water pump 60 is provided on the delivery pipe 80 for delivering the brine in the neutralization tank 10 to the brine tank 70. A second liquid level gauge 71 is provided in the brine tank 70 for monitoring the liquid level in the brine tank 70. Preferably, both the first liquid level gauge 11 and the second liquid level gauge 71 are photoelectric liquid level gauges that can detect multiple liquid levels and issue an alarm when the liquid level reaches its highest or lowest point.
[0030] The system also includes a control system. A water valve 31 is provided on the water inlet pipe 30 to control the flow of water in the water inlet pipe 30. The control system connects the water valve 31, the conveyor 20, the first liquid level gauge 11, and the salinity sensor 12. When the first liquid level gauge 11 detects that the liquid level in the neutralization tank 10 is at its lowest point, the elevator starts to add salt to the neutralization tank 10, the water valve 31 opens to convey water into the neutralization tank 10, and the air intake pipe opens to allow gas to enter the neutralization tank 10, thereby starting the preparation of brine. When the first liquid level gauge 11 detects that the liquid level has reached its maximum value, the control system issues a command to control the water valve 31 to close. When the salinity sensor 12 detects that the brine concentration has reached a set value, the control system issues a command to control the elevator to stop and close the air intake pipe 40, completing the preparation of brine.
[0031] The control system is electrically connected to the second liquid level gauge 71 and the water pump 60. When the second liquid level gauge 71 detects that the brine tank 70 is insufficient, that is, when the liquid level in the brine tank 70 is at its lowest point, the water pump 60 starts to pump the brine prepared in the neutralization tank 10 into the brine tank 70. When the second liquid level gauge 71 detects that the liquid level in the brine tank 70 is at its highest point, the water pump 60 stops, completing the replenishment of the brine in the brine tank 70.
[0032] In this embodiment, a plurality of brine tanks 70 are provided, and the plurality of brine tanks 70 are arranged in parallel on the delivery pipeline 80 to meet the use of multiple soft water systems in the production process in actual production.
[0033] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents; and such modifications or replacements do not deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
