Description

Technical Field

[0001] This utility model belongs to the field of electrolytic cell technology, specifically relating to an electrolytic cell with easily replaceable electrode plates. Background Technology

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode, with most separating the anode and cathode chambers 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. Optimizing the electrolytic cell structure and rationally selecting electrode and diaphragm materials are key to improving current efficiency, reducing cell voltage, and saving energy.

[0003] Existing electrolyzers can be used to produce hydrogen or oxygen, but the two electrode plates cannot be easily replaced, which reduces the scope of application and practicality. Furthermore, during use, the internal gas cannot be discharged, and if a large amount of toxic gas accumulates, it will affect normal use. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an electrolytic cell with easily replaceable electrodes, featuring convenient electrode replacement and timely gas discharge.

[0006] The disassembly and assembly mechanism includes a rectangular frame, the bottom of which is fixedly connected to the top cover. Grooves are provided at both ends of the rectangular frame. A limiting post is fixedly connected to the upper side of the electrode plate. A separation mechanism is provided at the end of the limiting post away from the electrode plate. The electrode plate is detachably connected to the separation mechanism through the limiting post.

[0007] Preferably, the separation mechanism includes a U-shaped plate, one side of which is fixedly connected to a limiting post, and a connecting rod is provided on the inner side of the U-shaped plate. A circular plate is fixedly connected to the bottom end of the connecting rod, and a pull rod is fixedly connected to the top end of the connecting rod.

[0008] Preferably, a handle is fixedly connected to the outer side of the pull rod.

[0009] Preferably, a sealing ring is provided at the top of the rectangular frame.

[0010] Preferably, the exhaust mechanism includes a housing, on both sides of which are provided a plurality of rows of air holes at equal intervals, and a fan is fixedly connected to the side of the housing near the air holes.

[0011] Preferably, a filter screen is fixedly connected to the lower inner side of the housing.

[0012] Preferably, two cover plates are provided on the side of the housing near the fan, and a connector is provided on the outer side of each of the two cover plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a disassembly and assembly mechanism. The upper side of the electrode plate is fixedly connected to a limiting post, which is made of insulating polytetrafluoroethylene to reduce the impact on the electrode plate. Hold the pull rod and insert the connecting rod into the U-shaped plate at one end of the limiting post. Then pull the pull rod upward. The circular plate drives the U-shaped plate and the electrode plate to move upward, so that the electrode plate can be separated from the top cover and the groove. The handle is made of rubber to prevent the pull rod from falling out of the hand. The sealing ring can reduce gas leakage from the gap after the electrode plate is inserted into the groove. By holding the pull rod and pulling the electrode plate upward, the electrode plate can be replaced at any time, thereby improving the practicality of the device.

[0015] 2. This utility model is equipped with an exhaust mechanism. The top cover has a slot at the box body, through which gas can enter the box body. The fan consists of an electric motor and fan blades. When the fan starts, a negative pressure is formed inside the box body, causing air to quickly gather upwards and then be discharged from the air vent. The filter screen can isolate liquids and reduce the electrolyte in the discharged gas. The cover plate is a hollow cabinet that can be placed on both ends of the box body to cover the air vents at both ends. The connector is then connected to an external gas pipeline, which can collect the discharged hydrogen and oxygen. By driving the fan to generate negative pressure, the gas can be discharged in time, avoiding the accumulation of harmful gases. Attached Figure Description

[0029] Specifically, the separation mechanism 34 includes a U-shaped plate 341. One side of the U-shaped plate 341 is fixedly connected to the limiting post 33. A connecting rod 342 is provided on the inner side of the U-shaped plate 341. A circular plate 343 is fixedly connected to the bottom end of the connecting rod 342. A pull rod 344 is fixedly connected to the top end of the connecting rod 342. By adopting the above technical solution, the upper side of the electrode plate 4 is fixedly connected to the limiting post 33, which reduces the impact on the electrode plate 4. Hold the pull rod 344 and insert the connecting rod 342 into the U-shaped plate 341 at one end of the limiting post 33. Then pull the pull rod 344 upward. The circular plate 343 drives the U-shaped plate 341 and the electrode plate 4 to move upward, so that the electrode plate 4 can be separated from the top cover 2 and the tank 1.

[0030] Specifically, a handle 345 is fixedly connected to the outside of the lever 344. The handle 345 is made of rubber to prevent the lever 344 from slipping out of the hand.

[0031] Specifically, a sealing ring 35 is provided at the top of the rectangular frame 31. The sealing ring 35 can reduce gas leakage from the gap after the electrode plate 4 is inserted into the groove 1.

[0035] The working principle and usage process of this utility model are as follows:

[0036] First, fill the tank 1 with electrolyte, and place the top cover 2 on top of the tank 1. The top of the top cover 2 has a slot for inserting the electrode plate 4.

Hold the pull rod 344 and insert the connecting rod 342 into the U-shaped plate 341 at one end of the limiting post 33. Then pull the pull rod 344 upward. The circular plate 343 drives the U-shaped plate 341 and the electrode plate 4 to move upward, so that the electrode plate 4 can be separated from the top cover 2 and the tank 1. The handle 345 is made of rubber to prevent the pull rod 344 from falling out of the hand. The sealing ring 35 can reduce gas leakage from the gap after the electrode plate 4 is inserted into the tank 1.

[0037] Subsequently, the top cover 2 has a slot at the housing 61, through which gas can enter the housing 61. The fan 63 consists of an electric motor and fan blades. When the fan 63 starts, it creates a negative pressure inside the housing 61, causing the air to quickly gather upwards and then be discharged from the vent 62. The filter screen 64 can isolate liquids and reduce the electrolyte in the discharged gas. The cover plate 65 is a hollow cabinet that can be placed on both ends of the housing 61 to cover the vents 62 at both ends. The connector 66 is then connected to the external gas pipeline to collect the discharged hydrogen and oxygen.

[0038] During use, the electrode plate 4 can be pulled up by holding the lever 344 to replace it at any time, improving the practicality of the device; by driving the fan 63 to generate negative pressure, the gas can be discharged in time to avoid the accumulation of harmful gases.
