DETAILED DESCRIPTION

[0016] Specific embodiments are provided below to further illustrate the present invention, but the present invention is not limited to the following embodiments.

[0017] The system mainly includes a salt-forming device, a control unit and a mobile terminal, and the mobile terminal can be a mobile phone or a computer.

[0018] As an example, Figure 1 As shown, it is an overall schematic diagram of the system. The salt-forming device includes a salt-forming container and a material container located above the salt-forming container. When the mobile terminal does not need remote control, the local start button on the control unit can be pressed to change the water.

[0019] The control unit is also equipped with a network switch and a main power switch, and an electronic screen on which users can set parameters.

[0020] The material container is preferably a square box 2, with transparent covers 3 on all four sides, which are fixed by screws. While preventing water vapor from entering, the operating conditions inside can also be seen, so as to facilitate operation.

[0021] The salt container can be a square salt box 1 with a volume larger than that of the square box 2. The square box 2 is placed on the salt box 1. A salt feeder 19 with a large upper part and a small lower part is provided in the square box 2 to facilitate the discharge of salt. The salt enters the salt box 1 through a discharge port of the salt box top plate 4 of the salt box 1.

[0022] The control unit is preferably installed in the square box 2, installed on one side of the square box 2 or in a space away from the salt feeder 19, and is used to control the entire system to change water, connect all electrical devices wirelessly or wired, and connect to the mobile terminal via a wireless network. The switch button on the control unit is fixed on the outer wall of the square box 2 for easy operation.

[0023] All electrical equipment, such as motors, solenoid valves, etc. are preferably fixedly installed in the square box 2 through mounting brackets.

[0024] First, it is convenient to connect the control unit, reduces the line settings, and avoids signal failure, no signal, etc. caused by interference from other signals, which affects the normal progress of the entire water change work.

[0025] Second, it is to avoid short circuit caused by contamination of water vapor. It is necessary to change water every week when raising marine fish in the family. There are many marine fish raised in the store, and the frequency of water change is also more frequent. Especially in summer, the weather is hot, water evaporates easily, and there is a lot of water vapor indoors, which can easily cause circuit short circuit and then dangerous situation. This system encapsulates all electrical equipment in the material box 2 to avoid the occurrence of dangerous situations. Moreover, the fish in the seawater tank occasionally splashes water and falls around the seawater tank. This method of the system completely avoids the occurrence of this situation and greatly increases the sense of security.

[0026] Third, it reduces the space occupied. The square box 2 and the salt tank 1 can be an integrated structure, and the pipes can be put in and out by drilling holes in the side walls of the square box 2. Rollers are provided under the salt tank, and only a little physical strength is needed to push it when it is not in use. It can be placed in a small space on the side of the seawater tank at home. The store can easily push it to each seawater tank to change the water. Physical strength is greatly reduced. Since the electrical appliances are installed in the square box 2 through the mounting bracket, the electrical appliances will not shake when moving, which increases the safety and practicality of the equipment.

[0027] like Figure 3 and Figure 4 As shown, the lower discharge port of the salt feeder 19 is provided with an electric control panel 20, which is controlled by the discharge port push rod stepper motor 32 to open or close the discharge port. After the salt adding process is completed, the electric control panel 20 closes the discharge port at the bottom or one side of the salt feeder 19 to prevent the salt feeder from getting damp.

[0028] The sea salt in the salt feeder 19 is transported into the salting tank 1 through the screw conveyor 36. The feeding speed regulating motor 21 drives the feeding screw of the screw conveyor 36 to rotate and can adjust the feeding speed. The feeding speed regulating motor 21 is connected to the control unit, and the feeding speed can be set on the mobile terminal. The feeding speed can be adjusted according to the temperature or the amount of water change, so as to carry out salting in the fastest time. Reduce the waiting time for salting.

[0029] The conveying rod of the screw conveyor 36 is provided with an outer wall and moisture-proof covers at both ends to prevent the salt material from getting damp and agglomerating during the conveying process.

[0030] A level meter is provided in the salt feeder 19, and a load-bearing level meter can be used. When it is detected that there is no sea salt in the salt feeder 19, the level meter feeds back information to the control unit, and the control unit stops the operation of the feeding speed regulating motor 21 and closes the electric control panel 20 of the salt feeder 19 through the discharge port push rod stepper motor 32.

[0031] A salt quantity monitoring probe 38 is installed on the side wall of the salt feeder 19, which is wirelessly connected to a mobile terminal. The situation of the salt material can be viewed through the mobile terminal, which is convenient for the user to add sea salt in time and check the feeding situation.

[0032] A discharge detection device and a vibrating motor 37 are installed near the discharge port of the salt feeder 19. The discharge detection device is used to detect whether the discharge is normal. Once there is no discharge, the vibrating motor 37 will vibrate the discharge port. The vibrating motor 37 can be installed slightly above the discharge port. After two vibrations, if there is no discharge, the control unit will alarm and push the alarm to the mobile terminal. The water replacement process is stopped.

[0033] It is also possible to determine whether the material is discharged normally by detecting the change in salinity of the salt tank 1. If the screw conveyor 36 keeps rotating within the set time, but the salinity does not change, it means that there is a jam, and the vibrating motor 37 vibrates the discharge port. If the salinity does not change after a certain period of time, the vibrating motor 37 vibrates the discharge port again. If the salinity does not change, the mobile terminal pushes a message to the alarm of the salt feeder 19 jamming the material, and stops the water replacement process.

[0034] One end of the RO main water pipe is connected to the RO machine, and the other end passes through the side wall of the square box 2. A TDS value monitoring sensor 30 is provided on the RO main water pipe in the square box 2. The RO main water pipe is divided into two branches in the square box 2, one branch is the RO water inlet pipe 24 of the salt container leading to the salt tank 1, and the other branch is the seawater tank water supply pipe 33 leading to the seawater tank.

[0035] When the TDS value monitoring sensor 30 detects that the TDS has reached the upper limit, the water supply is stopped and the mobile terminal is promptly alerted to inform the user to replace the RO machine filter as soon as possible.

[0036] like Figure 2 As shown, the desalination tank 1 has an RO water inlet on one side thereof, which is connected to the RO main water pipe through the RO water inlet pipe 24 of the desalination container, and is used to feed RO purified water filtered by the RO machine into the desalination container. The RO water inlet pipe of the desalination tank 1 is provided with a solenoid valve 25, and the solenoid valve is located in the square box 2.

[0037] The RO water inlet pipe outlet 7 is located near the top of the salt tank 1, and the pipe outlet is provided with an anti-overflow float valve 8. An anti-overflow float valve liquid level adjustment bracket 16 is installed on the top of the salt tank 1 to fix and adjust the anti-overflow float valve.

[0038] A salinity meter 10 is provided in the salt tank 1 and connected to the control unit. The user can set the value on the mobile terminal. A liquid level meter 11 is provided to control the water volume. The liquid level meter is located on a liquid level meter adjustment bracket 13 on one side of the bottom. The upper and lower limits of the water level can be set on the mobile terminal. Generally, the salinity is between 1.020% and 1.023%. The user can set the salinity value on the mobile terminal according to his or her own experience.

[0039] A circulation device is installed on the top of the salt tank 1, specifically, an n-shaped internal circulation pipe 9 is provided to extend to the bottom of the salt tank 1, and an internal circulation ball valve 17 is installed on the internal circulation pipe 9, which is controlled by an internal circulation water pump 12, and the internal circulation water pump 12 is connected to the control unit. The dissolution of the salt material is accelerated, and the salinity of the obtained new brine is uniform.

[0040] Because the salt will settle to the bottom, if internal circulation is not carried out, the time for salt dissolution will increase significantly, or the salt particles will not be completely dissolved, or the salinity will be uneven.

[0041] The inner circulation pipeline is connected to a drainage pipeline, on which an external drainage ball valve 18 is installed. If the water volume exceeds the upper limit of the liquid level meter 11, or the anti-overflow float valve 8 closes the solenoid valve on the RO water inlet pipeline 24, the water is drained through the drainage pipeline to prevent the water in the salt tank 1 from overflowing and flushing out of the tank.

[0042] The bottom of the salt tank 1 is provided with an inclined plate 5, and a heater 6 is provided with a heater support 15, and the heater 6 is located on the lower side of the inclined plate, and the two are close to each other. After a small amount of salt particles that are not completely dissolved sink to the bottom, they slide over the surface of the inclined plate 5 and fall near the heater 6 on the lower side of the inclined plate 5, which accelerates the dissolution of the salt material, not only making the salt material completely dissolved but also saving a lot of time.

[0043] The sea salt enters from the top. Because of the heating and circulation device of the heater 6 for the RO purified water, the sea salt particles that sink to the bottom will be relatively few, and will eventually settle to the lower side of the inclined plate 5. The heater 6 heats the salt material, thereby achieving complete and rapid dissolution. The dissolved salt material is then driven into the water flow along with the flow of the inner circulating water, so that the salinity in the salt tank 1 is uniform.

[0044] The heater 6 can also heat the water in the salt tank 1 to a specified temperature and feed it back to the control unit. Generally, the temperature of the seawater tank is maintained between 24 and 26 degrees. Different marine fish species or corals and anemones have specific temperatures. The temperature of the salt tank 1 can be set according to the conditions of the seawater tank.

[0045] The seawater tank water supply pipe 33 is also provided with a solenoid valve and the solenoid valve 25 on the salt container RO water inlet pipe 24 is fixed in the square box 2 through a mounting bracket and connected to the control unit.

[0046] A new water pipeline 14 leading to the seawater tank is provided in the desalination tank 1. The new water pipeline 14 extends from the top of the desalination tank 1 through the new water pipeline 26 of the desalination tank section to the new water peristaltic pump 22 located in the square box 2. After passing through the new water peristaltic pump 22, the new water enters the seawater tank filtration system through the new water pipeline 27 of the seawater tank section. The new water peristaltic pump 22 is connected to the control unit and is installed on the new water peristaltic pump bracket 23 fixed to the bottom of the square box 2.

[0047] In order to reduce the impact on the organisms in the seawater tank, a peristaltic pump is used to slowly change water and drain water.

[0048] A wastewater pipe 28 is provided in the seawater tank, and a wastewater peristaltic pump 34 is installed on the wastewater pipe. The wastewater peristaltic pump 34 is installed at the bottom of the square box 2 through a wastewater peristaltic pump mounting bracket 35 and is connected to a control unit. The wastewater peristaltic pump is connected to a wastewater pipe 29 leading to a wastewater tank section, and the water in the seawater tank is discharged to the wastewater tank, or to a sewer.

[0049] There are three water level gauges in the seawater tank, namely the upper limit water level, lower limit water level and water replenishment level. The upper limit and lower limit water levels are the upper and lower limit water levels of the seawater tank. Once the upper limit is exceeded or the lower limit is lower than the lower limit, the water intake or drainage will be stopped and an alarm will be issued.

[0050] Natural evaporation causes the water level in the seawater tank to drop. When it drops to the water replenishment level, the solenoid valve 31 on the seawater tank water replenishment pipeline is opened to replenish water. When the water level reaches the upper limit water level, the water replenishment stops and the solenoid valve 31 on the seawater tank water replenishment pipeline is closed.

[0051] The working process of the present system is described in detail below, taking operation on a remote mobile terminal as an example.

[0052] Set various parameter values ​​on the mobile terminal, such as: salinity of salt tank 1, upper and lower limits of salt tank 1 liquid level, TDS upper limit, conveyor speed, salt tank temperature, calibration of various sensors and flow rates for the first use, and set the full salting time. After setting the above parameters, click Start on the mobile terminal.

[0053] The controller receives the signal from the mobile terminal and starts to work. The electromagnetic valve 25 on the RO water inlet pipe of the salt tank 1 is opened, and after the water flows to the upper limit of the liquid level meter, the electromagnetic valve 35 on the RO water inlet pipe of the salt tank 1 stops working.

[0054] The circulating water pump 12 in the desalination tank is started, the circulating ball valve 17 in the desalination tank 1 is opened, and the water in the desalination tank begins to circulate.

[0055] The salt tank heater 6 is started, and after heating to the specified salt tank temperature, the heater stops working. Once the temperature drops, heating continues to be performed so that the temperature is maintained at the set temperature value.

[0056] The discharge port push rod stepper motor 32 opens the electric control panel 20 of the discharge port of the salt feeder 19, starts the feeding speed regulating motor 21, and the screw conveyor 36 transports the sea salt into the salt tank 1.

[0057] Salt has the characteristic of sticking to the wall. Within the set time, the salinity meter in the salt tank reports that the salinity has not changed, indicating that the material is stuck. The vibrating motor 37 starts vibrating for the set time. If the salinity does not change, it is turned on again. If the salinity does not change, the mobile terminal pushes a message that the material box is stuck, stops the screw conveyor, and closes the discharge door of the salt feeder 19.

[0058] After the salinity reaches the set value, the screw conveyor 36 stops working and the discharge port of the salt feeder 19 is closed. The salt is fully dissolved according to the set time.

[0059] After the desalination time is over, start the new water and waste water peristaltic pumps to change the water in the seawater tank. Two water exchange modes can be used.

[0060] The first type: two motors run at the same time, a new water pump pumps water from the brine tank into the seawater tank filtration system, and a wastewater peristaltic pump pumps water from the seawater tank filtration system into the sewer. It stops after running to the lower line value set by the liquid level meter, and the number of liters can also be set on the mobile terminal to stop.

[0061] Finally, the mobile terminal pushes a message that the water change is completed. If there is an imbalance in flow during operation, the water inlet and outlet will be stopped through the upper and lower limit water level gauges of the seawater tank to prevent the seawater tank from overflowing or being emptied without water to damage the filtration equipment.

[0062] The second method: first start the wastewater peristaltic pump to discharge the seawater tank water into the sewer, run it at full power according to the number of liters set on the mobile terminal, and stop the wastewater drive pump after the number of liters is reached.

[0063] Then start the new water drive pump to pump new water into the fish tank. When the set value is reached, the new water peristaltic pump stops.

[0064] Finally, the mobile terminal pushes a message that the water change is completed.

[0065] When the liquid level in the brine tank 1 is lower than the set lower limit, the circulating water pump is stopped and the heater is stopped to prevent damage due to lack of water.

[0066] Two operating modes can be selected on the mobile terminal.

[0067] There is evaporation in the seawater tank every day. In order to avoid the evaporation affecting the salinity and other trace elements, once the water level drops to the water replenishment level, the automatic water replenishment solenoid valve of the seawater tank opens to replenish the evaporation of the seawater tank.

[0068] This system only requires simple settings on the mobile terminal to complete the work of changing and replenishing water, and an adjustable angle monitoring probe can be installed at the appropriate position of the material box, and the process of changing water can be remotely viewed and operated on the mobile terminal, making the work of changing water in the seawater tank simple and easy.

[0069] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the present invention.
