Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, specifically to an assembled small sodium hypochlorite electrolytic cell. Background Technology

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode, with the anode and cathode chambers usually separated by a diaphragm. Based on the electrolyte, they are classified into three types: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface, to produce the desired product.

[0003] Existing small-scale sodium hypochlorite electrolyzers are relatively small in size and are generally designed as an integrated unit for easy handling, installation, and use. However, this integrated design makes internal cleaning difficult, and because small electrolyzers have low flow rates and slow speeds, the heat generated during electrolysis cannot be effectively released, resulting in high electrolyte temperatures. Excessively high electrolyte temperatures are detrimental to both the lifespan of the electrolyzer itself and the normal operation of the electrolysis process. Utility Model Content

[0004] The purpose of this invention is to provide an assembled small sodium hypochlorite electrolytic cell with good heat dissipation and the ability to filter incoming air.

[0005] This utility model is achieved through the following technical solution: an assembled small sodium hypochlorite electrolytic cell, comprising:

[0006] The cathode housing has an inlet located on the lower side of one side and an outlet located on the upper side of the other side. A cathode terminal is located in the middle of one side of the cathode housing.

[0007] A hollow tubular anode is inserted inside the cathode housing and extends out of the cathode housing at both ends. An anode terminal is installed on the top of the tubular anode.

[0008] An insulating layer that covers the outside of the cathode housing;

[0009] A sealing end cap is movably and sealingly installed at both ends of the tubular anode extending out of the cathode housing, and the sealing end caps at the upper and lower ends seal both ends of the cathode housing.

[0010] A connecting assembly is provided at both ends of the cathode housing, with at least two connecting assemblies fixedly installed on each end of the cathode housing, and the connecting assembly fixes the sealing end cap to the cathode housing.

[0011] The working principle of this technical solution is that the original anode plate is designed as a hollow tubular anode. The transparent design of the tubular anode can ensure good heat dissipation during the electrolysis process of the electrolytic cell. The cathode shell and the tubular anode are fixed together by the cooperation of the sealing end cap and the connecting component. The connecting component can easily and conveniently realize the overall installation and disassembly of the electrolytic cell, which greatly facilitates the subsequent cleaning and maintenance of the electrolytic cell.

[0012] To better realize this utility model, it further includes a heat dissipation fan fixed to the lower sealed end cover. A filter assembly is installed at the lower part of the heat dissipation fan. The heat dissipation fan blows air through the filter assembly toward the tubular anode. The air enters from the lower part of the hollow tubular anode and flows out from the upper part of the tubular anode.

[0013] To better realize this utility model, the filter assembly further includes a filter seat installed at the air inlet of the cooling fan, and a filter screen is installed at the lower part of the filter seat.

[0014] To better realize this utility model, one end of the filter screen is hinged to one side of the filter seat, and a pull rod is provided on the other side of the filter seat. The end of the filter screen is provided with a groove that matches the end of the pull rod. A sliding groove is provided in the filter seat above the pull rod. A slider that is fixedly connected to the pull rod is installed in the sliding groove. A spring is also installed between the slider and the inner wall of the sliding groove. The spring pushes the slider so that the pull rod is inserted into the groove at the end of the filter screen.

[0015] To better realize this utility model, the connecting assembly is further provided with a connecting seat fixedly connected to the cathode housing, a square insert fixed to the sealing end cover, a sliding clamping rod inserted into the outside of the connecting seat, and a slot on the square insert that matches the end of the clamping rod, so that the end of the clamping rod can be engaged or disengaged from the slot on the square insert by sliding the clamping rod.

[0016] To better realize this utility model, the connecting seat is further provided with a sliding groove, a reset block is provided in the sliding groove, and a reset spring is installed between the reset block and the inner wall of the sliding groove. The reset spring pushes the reset block so that the end of the clamping rod is engaged in the slot on the square plug.

[0017] To better realize this utility model, a guide slide is further provided at one end of the clamping rod.

[0018] To better realize this utility model, a sealing ring is further provided between the sealing end cap and the connecting seat.

[0019] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0020] (1) This utility model provides a new small sodium hypochlorite electrolytic cell, which designs the original anode plate as a hollow tubular anode. The permeable design inside the tubular anode can ensure that the electrolytic cell has a good heat dissipation effect during the electrolysis process. The fan installed at the bottom of the electrolytic cell can further improve the heat dissipation effect of the electrolytic cell, avoid the electrolyte temperature from being too high and causing damage to the electrolytic cell, and ensure the smooth progress of the electrolysis process.

[0021] (2) In this utility model, the cathode shell and the tubular anode are fixed by the cooperation of the sealing end cap and the connecting component. The electrolytic cell can be assembled and disassembled simply and easily by the cooperation of the connecting component and the sealing end cap, which greatly facilitates the subsequent cleaning and maintenance of the electrolytic cell.

[0022] (3) This utility model also provides a filter component at the air inlet of the heat dissipation fan, which can ensure the cleanliness of the air blown to the internal tubular anode and avoid the adverse effects of unclean air on the internal tubular anode. Its structure is reasonable and its functions are complete. It is especially suitable for small electrolysis equipment with less than 50L and is suitable for widespread application.

[0032] Example 1:

[0033] The main structure of this embodiment is as follows: Figure 1 , Figure 2 As shown, it includes:

[0034] A cathode housing 1 has an inlet 10 located on the lower side of one side of the cathode housing 1 and an outlet 11 located on the upper side of the other side of the cathode housing 1. A cathode terminal 8 is located in the middle of one side of the cathode housing 1.

[0035] A hollow tubular anode 2 is inserted inside the cathode housing 1 and extends out of the cathode housing 1 at both ends. An anode terminal 9 is installed above the tubular anode 2.

[0036] Insulating layer 3, which covers the outside of cathode housing 1;

[0037] A sealing end cap 6 is movably and sealingly installed at both ends of the tubular anode 2 extending out of the cathode housing 1, and the sealing end cap 6 at the upper and lower ends seals both ends of the cathode housing 1.

[0038] The connecting components 7 are disposed at both ends of the cathode housing 1, and at least two connecting components 7 are fixedly installed on each end of the cathode housing 1. The connecting components 7 fix the sealing end cap 6 to the cathode housing 1.

[0039] The specific implementation process is as follows: Assemble the electrolytic cell, embed the tubular anode 2 inside the cathode housing 1, and then install sealing end caps 6 at both ends of the tubular anode 2. The sealing end caps 6 seal both ends of the cathode housing 1. Use the connecting components 7 at both ends of the cathode housing 1 to fix the sealing end caps 6, so that a closed space for the flow of electrode liquid is formed between the cathode housing 1 and the tubular anode 2. Connect wires to the cathode terminal 8 on the cathode housing 1 and the anode terminal 9 on the tubular anode 2 to complete the assembly of the electrolytic cell. For safety, an insulating layer 3 needs to be covered on the surface of the cathode housing 1, and the sealing end caps 6 are also made of insulating materials, such as hard rubber or PVC.

[0040] A sodium chloride solution of a pre-mixed concentration is introduced into the sealed space between the cathode housing 1 and the tubular anode 2 through the inlet 10 below the cathode housing 1 for electrolysis. The hydrogen gas and sodium hypochlorite solution generated after electrolysis flow out from the outlet 11, and the heat generated by electrolysis is dissipated from the hollow interior of the tubular anode 2.

[0041] When maintenance or cleaning is required, simply first release the connection component 7 from the sealing end cap 6, then remove the sealing end cap 6 from the tubular anode 2 (only one end needs to be removed), and then remove the tubular anode 2 from the cathode housing 1, thus completing the disassembly process of the electrolytic cell.

[0042] Example 2:

[0043] This embodiment, based on the above embodiment, further adds a cooling fan 4 and a filter assembly 5, such as... Figure 1 As shown, the device also includes a cooling fan 4 fixed to the lower sealed end cap 6. A filter assembly 5 is installed at the lower part of the cooling fan 4. The cooling fan 4 blows air passing through the filter assembly towards the tubular anode 2. The air enters from the lower part of the hollow tubular anode 2 and flows out from the upper part. To improve the heat dissipation effect of the electrolytic cell, a cooling fan 4 is specifically provided to accelerate the flow of air from the lower part of the hollow tubular anode 2 to the upper part. Since there is no additional protective structure inside the tubular anode 2, a filter assembly 5 is added to prevent dust from entering the tubular anode 2 and affecting its normal operation, ensuring that all air entering the tubular anode 2 through the cooling fan 4 is filtered. Other parts of this embodiment are the same as those in the above embodiments and will not be described again.

[0044] Example 3:

[0045] This embodiment further defines the structure of the filter component 5 based on the above embodiments, such as... Figure 3As shown, the filter assembly 5 includes a filter seat 51 installed at the air inlet of the cooling fan 4, and a filter screen 52 is installed at the lower part of the filter seat 51. The filter screen 52 is installed at the air inlet of the cooling fan 4 using the filter seat 51 to prevent dust from entering. Other parts of this embodiment are the same as those in the above embodiments and will not be described again.

[0046] Example 4:

[0047] This embodiment further defines the structure of the filter component 5 based on the above embodiments, such as... Figure 3 As shown, one end of the filter screen 52 is hinged to one side of the filter base 51, and a pull rod 54 is provided on the other side of the filter base 51. The end of the filter screen 52 has a groove that matches the end of the pull rod 54. A sliding groove is provided inside the filter base 51 above the pull rod 54. A slider 53, fixedly connected to the pull rod 54, is installed in the sliding groove. A spring 55 is also installed between the slider 53 and the inner wall of the sliding groove. The spring 55 pushes the slider 53, causing the pull rod 54 to be inserted into the groove at the end of the filter screen 52. A further improved filter assembly 5 structure allows the filter screen 52 to be opened by pulling the pull rod 4, thus facilitating cleaning of both the filter screen 52 and the fan. In addition, to prevent the end of the pull rod 54 from slipping out of the slot at the end of the filter screen 52, a slider 53 and a spring 55 are specially provided so that the pull rod 54 can remain extended and locked in place with the filter screen 52. Only after pulling the pull rod 54 and overcoming the elastic force of the spring 55 can the pull rod be pulled out, allowing it to disengage from the slot at the end of the filter screen 52. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

A sliding clamping rod 73 is inserted into the connecting seat 71. The square insert 72 has a slot that matches the end of the clamping rod 73, allowing the end of the clamping rod 73 to engage or disengage from the slot by sliding the clamping rod 73. The fixing structure of the connecting assembly 7 is basically the same as that in the filter assembly 5, also using the clamping rod 73 to engage with the square insert 72 fixed to the sealing end cap 6 to fix the clamping rod 73 to the sealing end cap 6, thereby fixing the cathode housing 1 to the tubular anode 2. Other parts of this embodiment are the same as those in the above embodiments and will not be described again.

The reset spring 75 pushes the reset block 74 so that the end of the clamping rod 73 is engaged in the slot on the square insert rod 72. The reset block 74 and the reset spring 75 are provided to ensure that the clamping rod 73 can be stably inserted into the snap of the square insert rod 72. Only after overcoming the elastic force of the reset spring 75 can the clamping rod 73 be pulled out, so that the clamping rod 73 disengages from the slot on the square insert rod 72. The other parts of this embodiment are the same as those of the above embodiment, and will not be described again.

The other parts of this embodiment are the same as those of the above embodiments, and will not be described again.
