Description

Technical Field

[0001] This utility model relates to the field of sodium hypochlorite generators, and in particular to an electrode mounting structure for a sodium hypochlorite generator. Background Technology

[0002] A sodium hypochlorite generator is a device used to prepare sodium hypochlorite, a disinfectant for water bodies. Existing sodium hypochlorite generators first dissolve salt to prepare a saturated sodium chloride solution, then dilute the saturated sodium chloride solution to a specific concentration. During operation, the diluted sodium chloride solution is fed into an electrolytic cell for electrolysis to generate sodium hypochlorite solution.

[0003] As attached Figure 1-2 As shown, the two ends of the electrolytic cell 1 are sealed together by flange 11, and the metal bolts connecting to the inside of the electrolytic cell 1 pass through the central axis of flange 11. As electrodes for conducting the electrolysis circuit, the metal bolts at both ends of the electrolytic cell 1 are the positive and negative terminals, respectively. These metal bolts are connected to an external DC power supply via wires, and simultaneously, the positive and negative terminals are connected to electrode plates inside the electrolytic cell 1 (not shown in the figure). The DC power supply makes contact with the metal bolts through the metal connecting piece 2 at the end of the wire, thus enabling circuit conduction.

[0004] During long-term use, scale will accumulate in the electrolytic cell 1 and on the electrode plates. Scale buildup leads to a decrease in electrolysis efficiency, while increasing power consumption and heat generation. Therefore, it is necessary to periodically disassemble the flange 11 on the electrolytic cell 1 to clean the inside of the electrolytic cell 1 and the electrode plates. However, most sodium hypochlorite generators operate in environments with high humidity, and the surfaces of metal bolts and connecting plates 2 exposed to this environment for a long time are prone to rust, directly affecting conductivity. Moreover, cleaning also requires unscrewing the metal bolts to disassemble the connecting plates 2, and rusted bolts are prone to slippage and damage during repeated disassembly and unassembly. Therefore, it is necessary to design an electrode mounting structure that can effectively protect the electrodes. Utility Model Content

[0005] To address the problems existing in the prior art, where the metal electrodes at both ends of the electrolytic cell are prone to rusting due to long-term exposure to a humid environment, affecting their conductivity, the purpose of this utility model is to provide an electrode installation structure for a sodium hypochlorite generator. By setting two mutually cooperating connectors at the electrode connection position, the first connector and the second connector can be quickly assembled and disassembled without the use of any tools. Moreover, after the two are assembled, the electrodes are isolated and protected, preventing the electrodes from contacting humid air.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: An electrode mounting structure for a sodium hypochlorite generator is located on the outside of flanges at both ends of an electrolytic cell, with the electrode's axis coinciding with the flange's axis.

The conductive mechanism is fixed inside the second connector, and their center lines coincide. The conductive mechanism is conductive and connected to a wire. The first connector is fixed to the flange, and the electrode extends through the first connector. A locking pin is provided on the side wall of the first connector. The second connector includes a mating portion and a locking groove. The locking pin can enter the locking groove and engage with it.

[0007] The present invention is further configured such that: the diameter of the second connector is larger than the diameter of the first connector, the shape and size of the mating part are adapted to the first connector, and when the first connector is fully inserted into the mating part, the edge of the second connector toward the first connector is pressed against the flange.

[0008] The present invention is further configured such that: the snap-fit ​​groove includes an insertion groove and a locking groove, the length direction of the insertion groove is perpendicular to the locking groove, and the insertion groove is connected to the locking groove, and the length direction of the insertion groove is parallel to the axis direction of the second connector.

[0009] The present invention is further configured such that: the conducting mechanism includes a fixed tube and a connecting wire, the axis of the fixed tube coincides with the axis of the electrode and the second connector, the connecting wire is used to connect the fixed tube and the wire, the electrode is adapted to the fixed tube, and when the locking pin enters the locking groove, the electrode enters the fixed tube and contacts the fixed tube.

[0010] The present invention is further configured such that: the conducting mechanism further includes a spring and a sliding block, the sliding block is located inside the fixed tube, the side wall of the sliding block is in contact with the fixed tube and the sliding block can slide freely inside the fixed tube, and the spring is located between the bottom of the fixed tube and the sliding block.

[0011] The present invention is further configured such that the two ends of the spring are respectively fixedly connected to the bottom of the fixed tube and the sliding block.

[0012] The present invention is further configured such that: the end of the electrode is hemispherical, and the shape and size of the end of the sliding block facing the electrode are adapted to the end of the electrode.

[0013] The present invention is further configured such that: the second connector also includes a groove, the opening of which communicates with the mating portion, and the groove is used to store desiccant.

[0014] The present invention is further configured such that: the first connector is also provided with a connecting groove, the connecting groove is arranged around the electrode, and the connecting groove is connected to the groove when the first connector is fully inserted into the docking part.

[0015] Located on the outer side of the flanges at both ends of the electrolytic cell, with the electrode coinciding with the axis of the flange, the structure includes a first connector, a second connector, and a conductive mechanism. The axes of the first connector, the second connector, and the electrode coincide. The conductive mechanism is fixed inside the second connector, and their center lines coincide.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] As attached Figure 3-6 As shown, an electrode mounting structure for a sodium hypochlorite generator includes a first connector 3, a second connector 4, and a conductive mechanism 6. This mounting structure is located outside the flanges 11 at both ends of the electrolytic cell 1, with the flanges 11 coinciding with the axis of the electrode 12.

[0023] In this embodiment, electrode 12 is a cylindrical columnar structure with a hemispherical top. Electrode 12 is connected to the electrode plates inside the electrolytic cell 1. To form an electrolytic circuit, electrode 12 is made of a conductive material.

[0024] The first connector 3 is a cylindrical columnar structure, with its axis coinciding with the axis of the electrode 12. The first connector 3 is fixedly connected to the flange 11 or integrally formed therefrom. Furthermore, the length of the first connector 3 along its own axis is less than that of the electrode 12, thereby allowing the electrode 12 to pass through the first connector 3.

[0025] The first connector 3 has a locking pin 31 on its side wall for connecting and engaging with the second connector 4. The locking pin 31 is also a cylindrical structure with a hemispherical top, protruding from the side wall of the first connector 3. The axis of the locking pin 31 is perpendicular to the axis of the first connector 3.

[0026] As attached Figure 6-9 As shown, the second connector 4 is a cylindrical columnar structure with a diameter larger than that of the first connector 3.

[0027] The second connector 4 is recessed at the center of one end facing the first connector 3 to form a mating portion 41. The shape and size of the mating portion 41 are adapted to the first connector 3. When the second connector 4 is close to the first connector 3, the mating portion 41 can completely and just right accommodate the first connector 3. At this time, the edge sidewall of the second connector 4 is in close contact with the flange 11 and the bottom surface of the mating portion 41 is in close contact with the top surface of the first connector 3.

[0028] The second connector 4 has snap-fit ​​grooves 42 around the mating portion 41. The number of snap-fit ​​grooves 42 is equal to the number of snap-fit ​​pins 31, and their positions correspond one-to-one. In this embodiment, two snap-fit ​​pins 31 are symmetrically arranged on the outer side wall of the first connector 3, so the second connector 4 has a total of two snap-fit ​​grooves 42.

[0029] The snap-fit ​​groove 42 is generally similar to an L-shaped channel, and includes an insertion groove 421 and a locking groove 422. The length direction of the insertion groove 421 is parallel to the axis of the second connector 4, and the length direction of the insertion groove 421 is perpendicular to the locking groove 422. The end of the insertion groove 421 is connected to one end of the locking groove 422.

[0030] In actual operation, the second connector 4 can be rotated to align the locking pin 31 with the insertion groove 421. During the process of fastening the second connector 4 to the first connector 3, the locking pin 31 enters and penetrates the insertion groove 421. When the first connector 3 is fully inserted into the mating part 41, the locking pin 31 simultaneously reaches the connection point between the insertion groove 421 and the locking groove 422. At this point, rotating the second connector 4 allows the locking pin 31 to enter the locking groove 422, thus completing the locking engagement between the first connector 3 and the second connector 4. The friction between all contact surfaces of the first connector 3 and the second connector 4 ensures that they cannot rotate relative to each other, therefore the locking pin 31 cannot disengage from the locking groove 422, thereby maintaining the locking engagement between the first connector 3 and the second connector 4.

[0031] The conductive mechanism 6 is fixed inside the second connector 4, and their center lines coincide. The entire conductive mechanism 6 is conductive and connected to the power supply of the electrolytic cell 1 via a wire. The conductive mechanism 6 includes a fixed tube 61, a connecting wire 62, a spring 63, and a sliding block 64.

[0032] The fixing tube 61 is a cylindrical metal tube with one open end and one closed end, with the open end located on the side where the docking part 41 is located. The other end of the fixing tube 61 is connected to the power supply wire via the connecting wire 62 and is electrically conductive. In particular, a protective sleeve 7 is provided at the connection point between the wire and the connecting wire 62 to prevent the wire from being damaged by excessive bending during use.

[0033] The axis of the fixed tube 61 coincides with the axis of the second connector 4, and the diameter of the electrode 12 is adapted to the fixed tube 61. When the first connector 3 and the second connector 4 are engaged, the electrode 12 extends into the interior of the fixed tube 61, and the side wall of the electrode 12 contacts the inner wall of the fixed tube 61.

[0034] The sliding block 64 is located inside the fixed tube 61. The side wall of the sliding block 64 is in contact with the inner wall of the fixed tube 61, and the sliding block 64 can slide freely inside the fixed tube 61. The end of the sliding block 64 facing the electrode 12 is a hemispherical recess, so that it is adapted to the shape and size of the end of the electrode 12.

[0035] Spring 63 is located inside fixed tube 61, and its two ends are fixedly connected to the bottom of fixed tube 61 and sliding block 64, respectively. When electrode 12 is inserted into fixed tube 61, spring 63 is compressed, the end of electrode 12 contacts sliding block 64, and the side wall of electrode 12 contacts fixed tube 61, thereby ensuring the conduction of electrolysis circuit.

[0036] The second connector 4 is also provided with a groove 43. The groove 43 is an elongated blind hole formed on the bottom surface of the mating part 41, and its opening connects to the mating part 41. The groove 43 is used to store the desiccant 5 in the small package, and the desiccant 5 can be obtained directly from the market.

[0037] As attached Figure 4 and attached Figure 10 As shown, the first connector 3 is also provided with a connecting groove 32 surrounding the electrode 12. When the first connector 3 is fully inserted into the docking part 41, the connecting groove 32 can still communicate with the groove 43, so that the desiccant 5 in the groove 43 can adsorb the moisture in the space where the electrode 12 and the conducting mechanism 6 are located.

[0038] The implementation principle of the above embodiments is as follows: The first connector 3 is directly fixed to the flanges 11 at both ends of the electrolytic cell 1. The steps for installing the second connector 4 at both ends of the electrolytic cell 1 are as follows: After placing the desiccant 5 in the groove 43, adjust the second connector 4 so that the locking pin 31 is aligned with the insertion groove 421. Then, press the second connector 4 onto the first connector 3 until the first connector 3 is fully inserted into the mating part 41. At this time, rotate the second connector 4 so that the locking pin 31 enters the locking groove 422, and the first connector 3 and the second connector 4 are locked together. At this time, the axes of the first connector 3 and the second connector 4 coincide, the electrode 12 is in full contact with the conducting mechanism 6, and the electrolytic circuit is connected. When it is necessary to disassemble and clean the scale, rotate the second connector 4 in the opposite direction so that the locking pin 31 enters the insertion groove 421 from the locking groove 422. Then, pull the second connector 4 outward to release the locking engagement between the first connector 3 and the second connector 4.

[0039] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
