Description

TECHNICAL FIELD

[0001] The utility model relates to electrolytic equipment field, concretely is a sewage electrolytic cell with detachable electrode plate. BACKGROUND

[0002] With the development of society, the improvement of people's living standards, the total amount of sewage discharge in industry and life is increasing, which makes the treatment difficulty increasing, which brings difficulties to the green development of city. The existing technology generally adopts biological method, chemical method and electrolysis method to treat sewage. The biological method needs a large amount of aeration, and the biological reaction rate is slow, which takes a lot of time; and it can not remove harmful gases in water well, resulting in large odor of effluent. If chemical method is used, a large amount of chemical reagent needs to be invested, and the sludge formed needs subsequent treatment, and at present, no cheap and effective chemical reagent has been found, which increases the cost of sewage treatment. Because of its effective treatment method, the electrolysis method can treat sewage by electrode plate, so that the sewage forms electric flocculation, which has high efficiency and fast effect compared with traditional biochemical method, and has small pollution and low cost. Therefore, it has attracted high attention in the market.

[0003] The electrolytic equipment in the prior art is usually composed of electrode plates and electrolytic cells. The positive and negative electrode plates are installed in the electrolytic cell. The water inlet and water outlet are arranged on the tank body of the electrolytic cell, so that the sewage flows through the electrolytic area formed between the electrode plates when flowing through the electrolytic cell, and then the electrolysis reaction occurs, the macromolecular pollutants are decomposed into small molecular pollutants, and the small molecular flocculation formed by electrolysis is flocculated into a mass by the electrode plate with electric flocculation effect, and is deposited at the bottom of the electrolytic cell to form sludge for discharge. In order to enhance the electrolysis effect of the electrolysis device, a plurality of electrolytic electrode plates are usually arranged, such as the patent document with the application number CN202322946062.9, which discloses a multifunctional electrode plate capable of simultaneous electrolysis and electric flocculation. The multifunctional electrode plate comprises a plurality of mutually parallel metal plates, the metal plates include aluminum plates and iron plates, the aluminum plates and the iron plates are arranged in a mutually penetrating manner, and the two end metal plates are respectively connected to the positive and negative poles of an external power supply. A through hole is formed at each of the four vertices of the metal plate, and each corresponding through hole on each metal plate penetrates through the same connecting piece. The connecting piece is used to integrate all the electrode plates into an electrode plate whole, and the electrode plate whole is directly installed in the electrolytic cell to form a plurality of strong electrolysis areas, so that the electrolysis and electric flocculation effects are enhanced.

[0004] Although the above-mentioned method enhances the electrolysis effect by increasing the electrode plates, the pollutants in the sewage are not uniformly distributed in the sewage during the electrolysis process, so that the working conditions of each electrode plate are not the same, resulting in that some electrode plates are more likely to be worn out. In the prior art, the electrode plates are integrated into a whole by the connecting piece, so that when one of the electrode plates is replaced, all the electrode plates need to be disassembled and replaced, which is complicated and low in efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a wastewater electrolysis cell with detachable electrode plates, in order to solve the technical problem mentioned above in the prior art where the electrode plates are integrated as a whole, so that when one electrode plate is replaced in the later maintenance, the integrated electrode plates need to be completely disassembled, which is a complicated maintenance process and inefficient.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: a wastewater electrolysis cell with detachable electrode plates, comprising an electrolysis cell and several electrode plates, wherein a limiting member is fixedly connected to the electrolysis cell to limit the electrode plates, and the electrode plates and the limiting member are independently detachable.

[0007] The beneficial effects of this implementation plan are as follows:

[0008] 1. In existing technologies, when multiple electrode plates are used, they are usually integrated into a single unit before being installed in the electrolytic cell. However, when wastewater flows into the electrolytic cell, the water quality is uneven, with some areas having more pollutants than others. This leads to inconsistent wear on each electrode plate, resulting in damage to individual plates, which can also occur unexpectedly. Furthermore, in existing technologies where all electrode plates are integrated, replacing a damaged plate requires disassembling the entire integrated electrode. Therefore, the maintenance process for each electrode plate is cumbersome and inefficient. This application, however, designs a limiting component that is fixed to the electrolytic cell. Each electrode plate is independently connected to the limiting component and can be disassembled individually, allowing for the removal of only one electrode plate during replacement, thus significantly improving maintenance efficiency.

[0009] 2. Electrolysis electrode plates are typically used in wastewater electrolysis treatment where the wastewater source is the same and the electrode plates are made of the same material. Although the wear and tear of each electrode plate is different, the difference is not significant. Therefore, they are integrated into a whole. When one electrode plate is damaged, the others are also nearing the end of their service life, so the cost of replacing the whole unit is not particularly high. However, when using an electrolytic cell to perform electrolysis and electroflocculation simultaneously, the electrode plates are made of two or more materials. The wear and tear time of the electrolysis electrode plates and the electroflocculation electrode plates are completely different. Therefore, replacing the whole unit because one electrode plate is damaged is too costly. Therefore, this application iteratively upgrades and designs an electrolytic cell structure that allows for the individual replacement of electrode plates. For multifunctional electrode plates that perform both electrolysis and electroflocculation simultaneously, compared to the integrated structure, the individual disassembly structure of this application has lower maintenance costs and higher value.

[0010] Furthermore, the limiting component is a snap-fit ​​groove opened on the inner wall of the electrolytic cell, and the electrode plate is detachably connected to the electrolytic cell by inserting into the snap-fit ​​groove. The snap-fit ​​mechanism facilitates replacement.

[0011] Furthermore, the electrolytic cell is provided with a foam discharge outlet that penetrates the side wall of the electrolytic cell. The foam discharge outlet is located at the upper end of the snap-fit ​​groove and is connected to the snap-fit ​​groove.

[0012] Furthermore, the electrode plate is provided with flow holes, which are installed alternately vertically after being connected to the electrolytic cell.

[0013] Furthermore, the electrolytic cell is provided with a foam discharge channel, and the outside of the foam discharge outlet is connected to the foam discharge channel.

[0014] Furthermore, the limiting member is a mounting plate that is fixedly connected to the inner wall of the electrolytic cell. The mounting plate is provided with threaded holes, and the side of the electrode plate is also provided with threaded holes. The electrode plate is connected to the limiting member by bolts through the threaded holes. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] Figure 2 This is a schematic diagram of the electrode plate installation of this utility model. Detailed Implementation

[0017] The following detailed description illustrates the specific implementation method:

[0018] The reference numerals in the accompanying drawings include: electrolytic cell 1, water inlet pipe 11, water outlet pipe 12, snap-fit ​​groove 13, foam discharge outlet 14, foam discharge channel 15, electrode plate 2, flow hole 21, electrode plate lead rod 3, and electrode plate lead clamp 31.

[0019] Implementation, for example, attached Figures 1-2 As shown: A wastewater electrolysis cell with detachable electrode plates includes an electrolysis cell 1. The electrolysis cell 1 is a cuboid cavity formed by four side plates and a bottom plate. An inlet pipe 11 and an outlet pipe 12 are provided at the upper end of the opening of the electrolysis cell 1. The height of the outlet pipe 12 is lower than the height of the inlet pipe, so wastewater can flow from the inlet end of the electrolysis cell 1 to the outlet end by gravity.

[0020] like Figure 1 As shown, with the side where the water outlet pipe 12 is located as the outer front, a limiting member is provided on the inner wall of the electrolytic cell 1 in this embodiment. The limiting member is a snap-fit ​​groove 13, which is a groove carved into the inner wall of the electrolytic cell 1. It is carved on the inner walls of both the left and right sides of the electrolytic cell 1, and the left and right grooves correspond one-to-one. The cross-sectional diameter of the groove is consistent with the thickness of the electrode plate 2, and the width of the electrolytic cell 1 on the left and right sides is also consistent with the width of the electrode plate 2. Therefore, the electrode plate 2 can be inserted into the snap-fit ​​groove 13 to complete the fixation of the electrolytic cell 1 and the electrode plate 2.

[0021] The upper end of the snap-fit ​​groove 13 has a foam discharge outlet 14 that penetrates the side wall of the electrolytic cell 1. The length of the foam discharge outlet 14 is consistent with the installation length of the electrode 2, so that the foam generated by electrolysis can be quickly discharged to the foam discharge outlets 14 on both sides. The downwardly recessed groove of the snap-fit ​​groove 13 is connected to the foam discharge outlet 14. Foam discharge channels 15 are provided on the outer side walls of the electrolytic cell 14. The foam discharge channel 15 is a semi-circular tube structure cut from the central axis. Its semi-circular tube arc opening just covers the foam discharge outlet 14. After being bonded to the outer wall of the electrolytic cell 1, it forms a foam discharge channel. The foam discharged from the foam discharge outlet 14 can change direction and flow back and forth in the electrolytic cell through the foam discharge channel 15 and be discharged. Later, a hose can be used to connect to the foam discharge channel 15 for discharge.

[0022] The electrode plate 2 has several equidistant flow holes 21 drilled on it. During installation, if... Figure 2 As shown, the electrode plates 2 can be installed vertically and horizontally in the snap-fit ​​groove 13, so that the flow holes 21 are also vertically and horizontally staggered. When the sewage from the inlet pipe 11 enters the electrolytic cell 1, it will first fill the cavity separated by the first electrode plate 2 until the water level reaches the position of the flow hole 21, and then pass through the flow hole 21 to the cavity formed by the second electrode plate 2. Since the electrode plates 2 are installed vertically and horizontally, the flow hole 21 of the second electrode plate 2 is located at the bottom. Therefore, the sewage flows from the lower flow hole 21 into the cavity formed by the next electrode plate 2. This makes the sewage flow vertically and horizontally in the electrolytic cell 1, ensuring its electrolysis effect. After the installation is completed, the electrode wire rod 3 is used to guide the electrode wire to the top of the electrode plate 2, and the electrode plate wire clamp 31 is used to hold the electrode plate 2 for connection. The electrode plate wire clamp 31 is a metal clamp that connects to the wire.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
