Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water filtration, and particularly relates to a water treatment device for electrolyzing hydrogen gas. Background Art
[0002] Hydrogen-rich water is a kind of drinking water mixed with hydrogen gas. Specifically, hydrogen gas is mixed into drinking water and locked in the water to form hydrogen-rich water. At present, the hydrogen gas in hydrogen-rich water is usually obtained by electrolyzing water, and the water quality requirements for the electrolyzed hydrogen and oxygen are generally relatively high. Usually, pure water is used to electrolyze to obtain hydrogen gas. Otherwise, if there are positive and negative ions in the water, it will affect the electrolysis and even form toxic substances.
[0003] With the current use of hydrogen-rich water to raise livestock in the breeding field, a relatively large amount of hydrogen-rich water supply is required. However, the cost of obtaining hydrogen gas by completely electrolyzing pure water is relatively high, increasing the breeding cost. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a water treatment device for electrolyzing hydrogen gas to solve the problem of high cost of obtaining hydrogen gas by electrolyzing pure water in the prior art.
[0005] To achieve the above purpose, a water treatment device for electrolyzing hydrogen gas provided by an embodiment of the utility model is connected to a water source and an electrolytic cell. The water treatment device for electrolyzing hydrogen gas includes a first filtering device and a second filtering device connected in series. The first filtering device is connected to the input water source, and the second filtering device is connected to the electrolytic cell. A first electrode is provided at the upper end of the first filtering device, and a second electrode is provided at the lower end. The first electrode and the second electrode are respectively connected to the positive electrode and the negative electrode of a power supply.
[0006] Further, the first electrode and the second electrode are in a net cylinder structure and are respectively sleeved on the upper and lower ends of the filter element of the first filtering device.
[0007] Further, both the first filtering device and the second filtering device are ceramic filters. The ceramic filter includes an outer cylinder and a ceramic filter element. A bottom cover is provided at the bottom end of the outer cylinder, and a top cover is provided at the top end. A water inlet pipe is provided on the bottom cover, and the water inlet pipe is connected to the water source input end. A water outlet pipe is provided on the top cover, and the bottom end of the water outlet pipe extends into the outer cylinder. A stepped hole is provided at the bottom end of the water outlet pipe, and the open end of the ceramic filter element is sleeved in the stepped hole.
[0008] Further, a limiting ring is provided on the outer side of the lower end of the water outlet pipe, and the first electrode is sleeved on the limiting ring. One end of the water inlet pipe extends into the outer cylinder, and the second electrode is sleeved on the end of the water inlet pipe.
[0009] Further, the top cover is also provided with a backwash inlet pipe, and the bottom cover is also provided with a drain pipe; the backwash inlet pipe and the drain pipe are in a normally closed state.
[0010] Further, the outer cylinder is a transparent pipe.
[0011] One or more of the above technical solutions in the water treatment device for electrolyzing hydrogen provided by the embodiments of the present invention at least have the following technical effects:
[0012] 1. The first filtering device can be directly connected to the drinking water, and the second filtering device is connected to the first filtering device and the electrolytic cell. The drinking water is filtered through two levels of the first filtering device and the second filtering device, so that the particulate impurities in the drinking water can be filtered, and the particulate impurities are prevented from entering the electrolytic cell and affecting the electrolyzed water.
[0013] 2.

Therefore, the positive and negative ions in the drinking water can be respectively adsorbed on the outer sides of the first electrode and the second electrode, so that the filtered water does not contain or contains very few positive and negative ions. Therefore, it is possible to electrolyze ordinary drinking water to obtain hydrogen, reducing the cost. Description of the Drawings

[0022] In an embodiment of the water treatment device for electrolyzing hydrogen of the present utility model, please refer to Figures 1 to 3 ; The water treatment device for electrolyzing hydrogen is connected to a water source and an electrolytic cell. Thus, after filtering and purifying drinking water, electrolyzed water can be provided to the electrolytic cell to obtain hydrogen and oxygen.
[0023] Specifically, the water treatment device for electrolyzing hydrogen includes a first filtering device 100 and a second filtering device 200 connected in series. The first filtering device 100 is connected to the input water source, and the second filtering device 200 is connected to the electrolytic cell and the first filtering device 100. Among them, a first electrode 300 is provided at the upper end of the first filtering device 100, and a second electrode 400 is provided at the lower end. The first electrode 300 and the second electrode 400 are respectively connected to the positive and negative electrodes of the power supply.
[0024] The water treatment device of this embodiment can directly connect to drinking water with the first filtering device 100, and the second filtering device 200 is connected to the first filtering device and the electrolytic cell. The drinking water is filtered through two stages of the first filtering device 100 and the second filtering device 200, so that the particulate impurities in the drinking water can be filtered to avoid the particulate impurities entering the electrolytic cell and affecting the electrolyzed water. When the drinking water passes through the first filtering device 100, the first electrode 300 and the second electrode 400 are respectively connected to the positive and negative electrodes of the power supply, so that the positive and negative ions in the drinking water move in a definite direction. The metal ions move to the negative electrode, and the non-metal ions move to the positive electrode. Therefore, the positive and negative ions in the drinking water can be adsorbed on the outer sides of the first electrode 300 and the second electrode 400 respectively, so that the filtered water contains no or very few positive and negative ions. Therefore, it is possible to obtain hydrogen by electrolyzing ordinary drinking water, reducing the cost.
[0025] Furthermore, the first electrode 300 and the second electrode 400 are in a net cylinder structure and are respectively sleeved on the upper and lower ends of the filter element of the first filtering device 100. In this embodiment, the first electrode 300 and the second electrode 400 are arranged in a net cylinder structure, so that the surface areas of the first electrode 300 and the second electrode 400 can be increased, and thus the adsorption amounts of the positive and negative ions can be increased.
[0026] Furthermore, referring to Figure 2 and Figure 3 , both the first filtering device 100 and the second filtering device 200 are ceramic filters. The first filtering device 100 includes a first outer cylinder 110 and a first ceramic filter element 120. A first bottom cover 111 is provided at the bottom end of the first outer cylinder 110, and a first top cover 112 is provided at the top end. The first bottom cover 111 is provided with a first water inlet pipe 113, and the first water inlet pipe 113 is connected to the water source input end. The first top cover 112 is provided with a first water outlet pipe 114, and the bottom end of the first water outlet pipe 114 extends into the first outer cylinder 110. A first stepped hole 115 is provided at the bottom end of the first water outlet pipe 114, and the open end of the first ceramic filter element 120 is sleeved in the first stepped hole 115.
[0027] The second filtering device 200 includes a second outer cylinder 210 and a second ceramic filter element 220. A second bottom cover 211 is provided at the bottom end of the second outer cylinder 210, and a second top cover 212 is provided at the top end. The second bottom cover 211 is provided with a second water inlet pipe 213, and the second water inlet pipe 213 is connected to the water source input end. The second top cover 212 is provided with a second water outlet pipe 214, and the bottom end of the second water outlet pipe 214 extends into the second outer cylinder 210. A second stepped hole 215 is provided at the bottom end of the second water outlet pipe 214, and the open end of the second ceramic filter element 220 is sleeved in the second stepped hole 215.
[0028] In this embodiment, the first water inlet pipe 113 of the first filtering device 100 can be directly connected to a drinking water source. The second water inlet pipe 213 of the second filtering device 200 is connected to the first water outlet pipe 114, and the second water outlet pipe 214 is connected to an electrolytic cell. The drinking water that enters the first outer cylinder 110 from the first water inlet pipe 113 is filtered by the first ceramic filter element 220 and then enters the second outer cylinder 210 from the first water outlet pipe 114 and is further filtered by the second ceramic filter element 220.
[0029] Further, referring to Figure 2 , a limiting ring 116 is provided on the outer side of the lower end of the first water outlet pipe 114, and the first electrode 300 is sleeved on the limiting ring 116. One end of the first water inlet pipe 113 extends into the first outer cylinder 110, and the second electrode 400 is sleeved on the end of the first water inlet pipe 113. Thus, the installation and fixation of the first electrode 300 and the second electrode 400 are realized.
[0030] Further, referring to Figure 3 , an anti-rush water inlet pipe 500 is provided on both the first top cover 112 and the second top cover 212, and a drain pipe 600 is also provided on both the first bottom cover 111 and the second bottom cover 211; the anti-rush water inlet pipe 500 and the drain pipe 600 are in a normally closed state. In this embodiment, if the anti-rush water inlet pipe 500 is connected to pure water input, then the anti-rush cleaning water flow can be input into the interior of the ceramic filter element, and the dirt on the outer side wall of the ceramic filter element can be flushed down, so as to clean the filter element, and the sewage after cleaning can be discharged from the drain pipe 600.
[0031] Furthermore, in order to conveniently observe the internal conditions of the first filtering device 100 and the second filtering device 200, the first outer cylinder 110 and the second outer cylinder 210 are set as transparent pipes. Thus, it can be observed whether the filter element needs to be cleaned.
