Therefore, improvements are needed. Utility Model Content

[0004] To overcome the problems existing in related technologies, this utility model provides an electrochemical box and an electrolysis device to solve the technical problem of poor sealing effect of the electrochemical box and direct impact of sewage on the electrode plates.

[0005] According to a first aspect of the present invention, an electrochemical chamber is provided for mounting electrode plates, the electrochemical chamber comprising:

[0006] The reaction chamber has a reaction chamber, a first buffer chamber and a second buffer chamber, wherein the first buffer chamber and the reaction chamber are connected, and the second buffer chamber and the reaction chamber are also connected.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0027] like Figures 1 to 3 As shown, this utility model provides an electrochemical chamber for mounting electrode plates 30, which perform electrolysis when energized. The electrochemical chamber includes a reaction chamber 10 and an assembly cover 20. The reaction chamber 10 has a chamber structure, and the assembly cover 20 closes the opening of the reaction chamber 10.

[0028] The reaction chamber 10 has a hollow box structure, wherein the reaction chamber 10 has a reaction chamber 11, a first buffer chamber 12 and a second buffer chamber 13, the first buffer chamber 12 and the reaction chamber 11 are connected, and the second buffer chamber 13 and the reaction chamber 11 are connected.

[0029] The first buffer chamber 12 and the second buffer chamber 13 are respectively connected to the reaction chamber 11. The first buffer chamber 12 and the second buffer chamber 13 are used to buffer and temporarily store fluids to reduce the flow rate and impact force in the reaction chamber 11 and maintain the reaction stability in the reaction chamber 11.

[0030] Optionally, the first buffer cavity 12 and the second buffer cavity 13 are distributed on opposite sides of the reaction cavity 11 to achieve a centrally located reaction cavity 11. For example, the reaction cavity 11 has a rectangular structure, and the first buffer cavity 12 and the second buffer cavity 13 are located on two opposite rectangular surfaces.

[0031] Optionally, the first buffer chamber 12 and the second buffer chamber 13 are distributed on both sides where the reaction chamber 11 intersects, so as to realize the reversing fluid flow channel arrangement on both sides of the reaction chamber 11. For example, the reaction chamber 11 is a rectangular structure, and the first buffer chamber 12 and the second buffer chamber 13 are respectively located on two vertical rectangular surfaces.

[0032] The reaction chamber 11 is connected to the fluid delivery pipeline through the first buffer chamber 12 and the second buffer chamber 13, thereby avoiding direct connection between the reaction chamber 11 and the fluid delivery pipeline, reducing the flow rate within the reaction chamber 11, and thus increasing the reaction time within the reaction chamber 11 and improving the electrolysis effect. At the same time, the first buffer chamber 12 and the second buffer chamber 13 will also reduce the pressure within the reaction chamber 11, further reducing the risk of leakage.

[0033] The reaction chamber 11 has an open structure, and the top of the reaction chamber 11 is provided with an assembly port 19, through which the electrode plate 30 can enter the reaction chamber 11. Multiple guide grooves 18 are provided at intervals on the opposite side walls of the reaction chamber 11, extending towards the assembly port 19; the guide grooves 18 are used to define the electrode plate 30.

[0034] The guide groove 18 is located on the cavity wall of the reaction chamber 11 and forms a concave structure. Multiple guide grooves 18 are spaced apart. Each guide groove 18 can correspondingly define the edge of an electrode plate 30, thereby maintaining the circumferential support and positioning of the reaction chamber 10 on the electrode plate 30.

[0035] The assembly cover assembly 20 is detachably connected to the reaction chamber 10 and is sealed to the assembly port 19. The assembly cover assembly 20 can seal the assembly port 19, and the small sealing surface area can reduce the risk of leakage. Furthermore, the electrode plate 30 is inserted and fixed to the assembly cover assembly 20, and the power connection part of the electrode plate 30 is located on the outside of the assembly cover assembly 20, which facilitates power connection and conductivity.

[0036] Preferably, the mounting cover assembly 20 is provided with a through conductive hole 212, which is used to insert the positioning electrode plate to achieve insertion in a small space.

[0037] The top of the reaction chamber 11 is open for mounting the electrode plate 30, which reduces the opening area and the number of joints, thus reducing the risk of leakage.

[0038] like Figures 2 to 4As shown, in one embodiment, the reaction chamber 10 includes a first connecting hole 16, a second connecting hole 17, an inlet flange 14, and an outlet flange 15. The first connecting hole 16 connects the first buffer chamber 12 and the reaction chamber 11, and the second connecting hole 17 connects the second buffer chamber 13 and the reaction chamber 11. The first connecting hole 16 extends through the space between the first buffer chamber 12 and the reaction chamber 11, and the second connecting hole 17 extends through the space between the second buffer chamber 13 and the reaction chamber 11. Fluid flows sequentially through the inlet flange 14, the first buffer chamber 12, the first connecting hole 16, the reaction chamber 11, the second connecting hole 17, the second buffer chamber 13, and the outlet flange 15, and is connected through corresponding pipes.

[0039] Both the inlet flange 14 and the outlet flange 15 are equipped with flange connection structures. The inlet flange 14 is connected to the first buffer chamber 12, and the outlet flange 15 is connected to the second buffer chamber 13. The inlet flange 14 and the outlet flange 15 are connected and locked together by fasteners to form the flange joint of the pipeline, thus constructing a fluid flow pipeline.

[0040] Both the first connecting hole 16 and the second connecting hole 17 are configured as elongated holes, and are rectangular elongated holes with their length direction parallel to the insertion direction of the electrode plate 30. The first connecting hole 16 is located laterally to the reaction chamber 11 and is misaligned with the flow path between it and the electrode plate 30, thereby forming a tortuous flow path between the reaction chamber 11 and the electrode plate 30, prolonging the reaction time.

[0041] Furthermore, the center lines of the first connecting hole 16 and the second connecting hole 17 are staggered to guide the fluid input and output directions to be misaligned. This misalignment of the first connecting hole 16 and the second connecting hole 17 guides the fluid to flow in and out, utilizing the spatial structure of the electrochemical chamber itself to change the internal flow direction and improve the smooth flow of the fluid.

[0042] Furthermore, the first connecting hole 16 and the inlet flange 14 are offset, and the second connecting hole 17 and the outlet flange 15 are also offset. The first connecting hole 16 and the inlet flange 14 are located on opposite sides of the first buffer chamber 12 to form an offset, thus creating an initial buffer for the fluid in the first buffer chamber 12. The second connecting hole 17 and the outlet flange 15 are located on opposite sides of the second buffer chamber 13 to form an offset, thus creating an output buffer for the fluid in the second buffer chamber 13.

[0043] Preferably, the first connecting hole 16 is an elongated hole structure, and the inlet flange 14 is a circular hole channel, wherein the channel area of ​​the inlet flange 14 is smaller than the channel area of ​​the first connecting hole 16, so as to form input pressure relief, reduce flow rate and avoid deposition in the first buffer chamber 12.

[0044] The volume of the first buffer chamber 12 is greater than or equal to the volume of the second buffer chamber 13. A buffer space is formed between the first buffer chamber 12 and the second buffer chamber 13, which facilitates the control of the flow rate of the fluid in the input and output directions.

[0045] In one embodiment, the ratio of the volume of the first buffer chamber 12 to the volume of the reaction chamber 11 is A, where 0.3 ≤ A ≤ 0.8. The volume of the reaction chamber 11 is greater than the volume of the first buffer chamber 12. After the fluid enters the reaction chamber 11 from the first buffer chamber 12, an electrolytic reaction is formed in the reaction chamber 11.

[0046] In one embodiment, the assembly port 19 is located at the top of the reaction chamber 11, and the assembly cover assembly 20 covers the reaction chamber 10 and closes the assembly port 19.

[0047] The assembly cover 20 includes an upper cover plate 21 and a seal 22, which is made of an elastic material, such as rubber. The seal 22 has an annular structure and surrounds the assembly opening 19. The upper cover plate 21 is pressed against the seal 22 to compress the seal 22 into elastic deformation, thereby forming a sealing surface.

[0048] Preferably, the seal 22 is configured as a stepped structure, with at least a portion of the upper cover 21 snapping into the stepped portion to form a multi-faceted seal.

[0049] Optionally, the upper cover plate 21 is provided with a protruding pressing boss 211, which surrounds the edge of the upper cover plate 21 to form a stepped structure at the edge.

[0050] The assembly port 19 is provided with an assembly groove, which surrounds the assembly port 19 to form an annular recess. The seal 22 is confined within the assembly groove to form a positioning seal. At the same time, the pressing boss 211 is embedded in the assembly groove to form a stepped multi-seal, wherein the seal 22 achieves multiple seals in the circumferential and bottom directions.

[0051] Preferably, the two outward-facing sides of the seal 22 are configured as convex spherical surfaces or multi-rib structures to achieve multi-point sealing.

[0052] like Figures 3 to 5 As shown, the electrochemical box disclosed in the above embodiments is applied to an electrolysis device, wherein the electrolysis device includes multiple electrode plates 30 and an electrochemical box. The electrode plates 30 are inserted and assembled into the electrochemical box along the guide groove 18 and are located in the reaction chamber 11. There is a flow channel between two adjacent electrode plates 30.

[0053] The edge of the electrode 30 is defined by the guide groove 18, and a flow channel is formed between the electrode 30 and the electrochemical box or between the electrodes 30. When energized, the electrode 30 can electrolyze harmful substances in the fluid, thereby decomposing the corresponding harmful substances in the fluid.

[0054] Optionally, a fluid gap is provided between the electrode plate 30 and the wall of the reaction chamber 11 to allow fluid to flow.

[0055] Optionally, the electrode plate 30 has holes to allow fluid flow.

[0056] In a preferred embodiment, adjacent flow channels are sequentially staggered and connected. The staggered arrangement of adjacent flow channels can extend the flow path and the electrolysis reaction time, thereby improving the electrolysis efficiency and ensuring thorough electrolysis of the fluid.

[0057] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary technical means in the art that are not disclosed in this invention.
