Specific implementation

[0032] In order to make the purpose, technical scheme and advantage of the utility model more clear, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the scope of the utility model.

[0033] Referring to Figures 1-8 The utility model provides electrolytic sewage treatment device, including:

[0034] Support frame 7, the upper portion of support frame 7 is provided with reaction tank 2, and reaction tank 2 top is opened, which is convenient for subsequent cleaning;

[0035] Gas collecting cover 5 is arranged above reaction tank 2, and the top of gas collecting cover 5 is provided with exhaust pipe 4; during sewage treatment, the gas generated by reaction is collected through gas collecting cover 5 and is led out to external gas treatment equipment through exhaust pipe 4 for treatment;

[0036] Copper bar 3 is arranged on the side wall of reaction tank 2, and current is dispersed to each electrode group 12 through copper bar 3 for power supply, so as to cooperate with chemical reaction;

[0037] The electrode group 12 is plug-in mounted in the reaction tank 2 and connected with the copper bar 3 through bolts. The electrode group 12 is divided into positive electrode plates 1201 and negative electrode plates 1202, which are arranged alternately in the reaction tank 2. The surface of the electrode plates in the electrode group 12 is provided with through holes for water flow, which can not only play a filtering role, but also increase the probability of contact between the electrode plates and sewage, thereby improving the sewage treatment effect. The positive electrode plates 1201 adopt a tensile net structure, and the negative electrode plates 1202 adopt a punched plate structure. Such a structure design can guide the water flow to pass through the net holes in an orderly manner, thereby improving the reaction efficiency.

[0038] The direct current power supply 6 is arranged on one side of the support frame 7 and used for supplying power to the copper bar 3. The direct current power supply 6 is connected with the mains and introduced into the copper bar 3 after voltage transformation.

[0039] The water inlet pipe 9 is arranged at the bottom of the reaction tank 2 and connected with one end of the reaction tank 2. The sewage is introduced into the water inlet pipe 9 through the water pump and finally flows into the reaction tank 2 for purification treatment.

[0040] The water outlet pipe 1 is arranged at the bottom of the reaction tank 2 and connected with the other end of the reaction tank 2. The purified sewage passes through the reaction tank 2 and finally leaves the reaction tank 2 to realize batch treatment of the sewage.

[0041] In use, the sewage is introduced into the reaction tank 2 from the water inlet pipe 9 and contacts the electrode group 12 when passing through the reaction tank 2. At the same time, the direct current power supply 6 supplies power to the electrode group 12 through the copper bar 3 to facilitate chemical reaction, thereby reducing the heavy metal ions in the sewage. The through holes on the surface of the electrode group 12 screen the recesses, thereby filtering out the waste residues. Finally, the treated sewage is introduced into the water outlet pipe 1 to realize complete treatment of the sewage.

[0042] In another embodiment, the inner bottom surface of the reaction tank 2 is provided with a residue discharge channel 11, and the inner bottom surface of the reaction tank 2 is provided with a residue discharge pipe 10 connected with the residue discharge channel 11. Since the sewage is in constant contact with the electrode group 12 during the treatment process, the sewage is often screened out by the through holes on the surface of the electrode group 12 and gradually falls to the bottom of the reaction tank 2 under the action of gravity. In order to facilitate the filtered waste residues to be quickly discharged out of the reaction tank 2, the bottom edge of the electrode group 12 is still away from the bottom of the reaction tank 2 after being installed in the reaction tank 2, i.e. the residue discharge channel 11. The waste residues after reaction are introduced into the residue discharge pipe 10 through the residue discharge channel 11 and finally discharged out of the equipment. Through the design of the residue discharge structure, the efficiency of residue discharge during the sewage treatment process can be significantly improved, thereby ensuring the treatment capacity.

[0043] In another embodiment, the inner wall of the reaction tank 2 is provided with a groove for inserting the electrode group 12. The groove can cooperate with the electrode plate in the electrode group 12 to position the electrode group 12. This design can reduce the installation difficulty during insertion and improve the stability of the electrode group 12, so that the electrode group 12 can always be inside the groove during the subsequent sewage treatment process to maximize the contact area with the sewage.

[0044] In another embodiment, the reaction tank 2 is internally provided with a vertically installed water level control plate 13, and the reaction tank 2 is provided with evenly distributed water blocking plates 14. The number of water blocking plates 14 is three, and the electrode group 12 is internally installed. The height of the water level control plate 13 is higher than the height of the water blocking plate 14. After the sewage to be treated is introduced into the reaction tank 2 through the water inlet pipe 9, it will first accumulate in the gap between the reaction tank 2 and the water level control plate 13. When the amount of sewage is large enough, it will overflow from the top of the water level control plate 13 into the gap between the water blocking plate 14 and the water level control plate 13, and then contact the electrode plate group. During the contact process, the water flow flows through the mesh and perforations of the positive and negative electrode plates to realize the chemical reaction of sewage treatment. Finally, after moving through multiple water blocking plates 14, the sewage is discharged from the water outlet pipe 1 to realize the whole sewage flow process.

[0045] In another embodiment, the lower part of the reaction tank 2 is provided with a cooling water pipe for cooling the direct current power supply 6. The cooling water pipe is used to continuously cool the direct current power supply 6 to improve the stability of the equipment.

[0046] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
