Description

Technical Field

[0001] The present invention relates to the technical field of mineral water production, in particular to a filtering device for mineral water production and a use method thereof. Background Art

[0002] Mineral water is uncontaminated underground water that emerges naturally or is artificially exposed from deep underground. It contains a certain amount of mineral salts, trace elements, or carbon dioxide gas. Under normal circumstances, its chemical composition, flow rate, water temperature, and other dynamics are relatively stable within the natural fluctuation range. Mineral water circulates deep within the earth's strata and contains minerals and limited indicators specified by national standards. During the mineral water production process, some impurities and particulates in the water must be filtered and removed.

[0003] Existing filtering devices usually use filtering consumables for filtration. Since mineral water is drinking water, in order to ensure the safety of the water body, the filtering consumables need to be replaced after filtering once.

[0011] Preferably, electric push rods are fixedly installed on both sides of the butt joint, and an electromagnet is fixedly installed on the telescopic end of the electric push rod. The electromagnet is magnetically connected to the magnetic joint, and a limiting groove is provided at the rear end of the electromagnet.

[0012] Preferably, a control valve is fixedly installed on the outer wall of the docking joint, a control mechanism is fixedly installed on one side of the electric push rod, and the output end of the control mechanism is electrically connected to the input end of the control valve, the electric push rod, and the electric telescopic rod, and a display screen is fixedly installed above the docking joint, and the input end of the display screen is electrically connected to the output end of the control mechanism.

[0013] Preferably, a first water storage container is fixedly installed inside the water receiving box, a liquid level meter is fixedly installed on the upper end of the first water storage container, and the output end of the liquid level meter is electrically connected to the input end of the control mechanism, and a water inlet cover is fixedly installed on one side of the liquid level meter.

[0014] Preferably, a second water storage container is fixedly installed inside the water storage tank, and an ultraviolet sterilization lamp is fixedly installed above the inside of the second water storage container.

[0015] Preferably, a scale bar is fixedly mounted on the outer wall of the water storage tank, and a transparent acrylic plate is fixedly mounted on the outer wall of the second water storage container.

[0016] Preferably, a delivery pipe is fixedly mounted on one end of the second water storage container via a flange.

[0017] Preferably, a method for using a filtering device for mineral water production comprises the following steps:

[0018] Step 1: Install multiple filters on the fixed rod in advance, connect the water inlet cover to the water pipe to let water in, and the stepper motor drives the sprocket to rotate through the transmission shaft. The chain follows the rotation and drives the filter to move, so that the filter moves to the position of the docking joint;

[0019] Step 2: The control mechanism controls the electric push rod to extend forward, the electromagnet is energized to generate magnetism, and the electric push rod is used to press the electromagnet against the magnetic joint so that the two are magnetically fixed. The electric push rod retracts backward, so that the telescopic tube is pulled and extended, and the electromagnet is retracted into the limit groove, and the plug of the magnetic joint is inserted into the slot of the butt joint. The extension of the electric telescopic rod makes the plug fit into the slot, thereby achieving the effect of fixing the magnetic joint and the butt joint together;

[0020] Step 3: The control mechanism opens the control valve, allowing the mineral water in the first water storage container to enter the filter element of the filter element from the water inlet pipe for filtration. The impurities and particles in the mineral water are blocked by the filter element, and the water overflows outward and enters the spiral flow channel through the through hole. The water moves along the spiral flow channel, and the impurities and particles in the water are removed by the filter mesh and water purification activated carbon provided in the flow channel. The holes of the filter mesh inside the spiral become smaller as the spiral moves toward the outer circle, so that the water is filtered step by step in the spiral flow channel and flows into the second water storage container from the water outlet pipe for storage. The mineral water in the second water storage container is sterilized by the ultraviolet sterilization lamp and is transported outward to the subsequent equipment through the delivery pipe.

[0021] Step 4: When the set flow rate is reached, the control mechanism uses the control valve to close, stopping the delivery of mineral water, and the electric telescopic rod retracts, so that the movement of the insert is no longer restricted. The electric push rod drives the electromagnet to extend forward, so that the telescopic tube is pushed and retracted, thereby achieving the effect of separating the magnetic joint from the docking joint. After the telescopic tube retracts to the initial position, the electromagnet is powered off and demagnetized, and retracts into the limit groove. The stepper motor drives the sprocket and chain to transmit, removes the used filter element, and the unused filter element is moved to the docking joint for re-filtration.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention filters mineral water by feeding it into the filter element of the filter. Impurity particles in the mineral water are blocked by the filter element, and the water overflows outward and enters the spiral flow channel through the through hole. The water moves along the spiral flow channel, and the impurity particles in the water are removed by the filter mesh and water purification activated carbon arranged in the flow channel. The more the spiral moves toward the outer circle, the smaller the hole diameter of the internal filter mesh is, so that the water is filtered step by step in the spiral flow channel. Since the internal flow adopts a spiral manner, the user can increase the internal flow time and filtration times of the water by increasing the spiral flow channels, so that the water can be filtered multiple times by multiple spiral flow channels, multiple filter meshes and clean water particles in the filter element, so that the filtering effect of the filter mechanism on mineral water is improved.

[0024] 2. The control mechanism controls the electric push rod to extend forward, and the electromagnet is energized to generate magnetism. The electric push rod is used to press the electromagnet against the magnetic joint so that the two are magnetically fixed. The electric push rod retracts backward, so that the telescopic tube is pulled and extended, and the electromagnet is retracted into the limit slot, and the plug of the magnetic joint is inserted into the slot of the docking joint. The plug is engaged in the slot through the extension of the electric telescopic rod, which has the effect of fixing the magnetic joint and the docking joint. When the set flow rate is reached, the control mechanism uses the control valve to close, so that the mineral water is stopped from being transported, and the electric telescopic rod retracts so that the plug no longer moves. The electric push rod drives the electromagnet to extend forward, so that the telescopic tube is pushed and retracted, thereby achieving the effect of separating the magnetic joint from the docking joint. After the telescopic tube retracts to the initial position, the electromagnet is powered off and demagnetized, and retracts into the limit groove. The stepper motor drives the sprocket and chain to transmit, and the used filter element is removed, and the unused filter element is moved to the docking joint for re-filtration. The above structure can automatically replace the filter element, and the filter element docking and assembly process can also be automated, thereby ensuring the filtering effect of mineral water and facilitating user use.

[0045] See also Figure 1-6 A method for using a filtering device for producing mineral water comprises the following steps:

[0046] Step 1: Pre-install multiple filter elements 9 on the fixed rod 10, connect the water inlet cover 28 to the water pipe to let water in, and the stepper motor 6 drives the sprocket 7 to rotate through the transmission shaft. The chain 8 follows the rotation and drives the filter element 9 to move, so that the filter element 9 moves to the position of the docking joint 20;

[0047] Step 2: The control mechanism 25 controls the electric push rod 21 to extend forward, and the electromagnet 22 is energized to generate magnetism. The electric push rod 21 is used to press the electromagnet 22 against the magnetic connector 14, so that the two are magnetically fixed.

[0048] Step 3: The control mechanism 25 opens the control valve 24, allowing the mineral water in the first water storage container 29 to enter the filter element 15 of the filter element 9 from the water inlet pipe 11 for filtration. The impurities and particles in the mineral water are blocked by the filter element 15, and the water overflows outward and enters the spiral flow channel 17 through the through hole 16. The water moves along the spiral flow channel 17 and is removed from the impurities and particles in the water by the filter mesh 18 and water purification activated carbon 19 provided in the flow channel. The holes of the filter mesh 18 become smaller as the spiral moves toward the outer circle, so that the water is filtered step by step in the spiral flow channel 17 and flows from the water outlet pipe 12 to the second water storage container 30 for storage. The mineral water in the second water storage container 30 is sterilized by the ultraviolet sterilization lamp 31 and is transported outward to the subsequent equipment through the delivery pipe 33.

[0049] Step 4: When the set flow rate is reached, the control mechanism 25 uses the control valve 24 to close, stopping the delivery of mineral water, and the electric telescopic rod 37 retracts, so that the movement of the insert 35 is no longer restricted. The electric push rod 21 drives the electromagnet 22 to extend forward, so that the telescopic tube 13 is pushed and retracted, thereby achieving the effect of separating the magnetic joint 14 from the docking joint 20. After the telescopic tube 13 retracts to the initial position, the electromagnet 22 is powered off and demagnetized, and retracts into the limit groove 23. The stepper motor 6 drives the sprocket 7 and the chain 8 to transmit, and the used filter element 9 is removed, and the unused filter element 9 is moved to the docking joint 20 for re-filtration.
