Description

Technical Field

[0001] The utility model relates to the technical field of diaphragmless electrolytic cells, in particular to a diaphragmless electrolytic cell with an exhaust structure. Background Art

[0002] There is no diaphragm inside the diaphragmless electrolyzer. The liquid level tank is lower than that of the previous diaphragm electrolyzer, and the operating voltage is also lower, which saves energy and reduces operating costs. The electrolyte is transported through pipelines, and then under the operation of positive and negative ions inside the battery, the anode and cathode produce oxidation and reduction reactions with the solution interface respectively, and then the required gases and other substances are produced.

[0003] However, previous diaphragmless electrolyzers often used cross bars to assemble various parts, which were inserted between the side plates on both sides to prevent the anode electrodes, cathode electrodes and other objects from being dispersed. However, there was a lack of necessary connection between the rod body and the slot, and the electrolyzer operated quite loosely and was likely to shake.

[0004] Now, a new type of diaphragmless electrolyzer with an exhaust structure is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a diaphragmless electrolytic cell with an exhaust structure to solve the problem that the electrolytic cell frame is easy to loosen in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a diaphragmless electrolytic cell with an exhaust structure, comprising a side plate and a liquid inlet, a bipolar plate fixed to the surface of the side plate, and a gasket arranged at the center between the bipolar plates, a cathode electrode mounted on the left side of the gasket, and an anode electrode mounted on the right side of the gasket, an air outlet pipe fixed to the top of the other side of the side plate, and a liquid inlet fixed to the bottom of the other side of the side plate, notches are respectively arranged on the upper and lower sides inside the side plate, and a reinforcement rod is horizontally inserted between the notches, limiting grooves are respectively arranged on both sides of the reinforcement rod, and a clamping rod is arranged between the front and rear of the inner side of the limiting groove, spring shafts are respectively arranged between the two ends of the clamping rod and the limiting groove, and a frosted pad is fitted on the surface of the clamping rod.

[0007] Preferably, two sides of the reinforcement rod are respectively embedded in the notches, and the clamping rod can swing left and right in the limiting groove.

[0008] Preferably, the anode electrode and the cathode electrode are fixedly connected to the bipolar plates respectively, and the anode electrode and the cathode electrode are symmetrically arranged on both sides of the gasket.

[0009] Preferably, a metal sheet is welded to the front end of one side of the bipolar plate, and an engagement groove is provided on one side inside the metal sheet, a circular hole is provided on the side of the engagement groove, a bolt is screwed into the engagement groove, and a threaded groove is provided on the surface of the bolt.

[0010] Preferably, the raised pattern of the thread groove matches the engagement groove, and the bolt can be screwed in and out of the engagement groove horizontally.

[0011] Preferably, the circular hole, the meshing groove and the bolt are arranged in concentric circles, and the spiral groove of the thread groove can be clamped by the metal copper wire.

[0012] Preferably, an air pump is installed on the air outlet pipe, a pipe mouth is provided at the top of the air outlet pipe, and a block is provided on the outside of the pipe mouth, a ring is fixed on the surface of the block, a fine-pore filter membrane is fixed on the upper part of the block, a medium-sized filter membrane is fixed at the center of the block, and a coarse-pore filter membrane is fixed on the lower part of the block.

[0013] Preferably, the medium filter membrane is suspended at the center of the fine-pore filter membrane and the coarse-pore filter membrane, and the medium filter membrane, the medium filter membrane and the medium filter membrane are in the same vertical plane.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the membrane-free electrolytic cell with an exhaust structure not only avoids loosening of the frame and reinforces the connection harness, but also filters out debris;

[0015] (1) By providing notches on the upper and lower sides of the inner side plate, when assembling the side plate, bipolar plate, anode electrode and cathode electrode, it is necessary to insert the reinforcing rod between the horizontal notches, and it is necessary to turn the clamping rods on both sides in advance so that they are located laterally on the sides of the reinforcing rods. After the reinforcing rods pass through the notches, the clamping rods are released. After the spring shaft is reset, the clamping rods are forced to fit on the surface of the side plate through the frosted pad for reinforcement, so as to prevent the reinforcing rods from loosening and prevent the internal components from separating;

[0016] (2) By welding a metal sheet at the front end of one side of the bipolar plate, the bolt with a threaded groove can be manually screwed in and out of the meshing groove, so that the metal wire rod with the rubber peeled off is completely wrapped around the bolt surface, and then the bolt in the meshing groove is continuously screwed to receive the bolt connected to the wire harness into the round hole, thereby preventing the wire harness from being separated from the insertion position;

[0017] (3) By setting a pipe opening at the top of the outlet pipe and inserting a plug with a collar into the outlet pipe, when the internal reaction produces hydrogen and other gases, they will be injected into the outlet pipe under the operation of the air pump, and then pass through the coarse-pore filter membrane, medium-pore filter membrane and fine-pore filter membrane from bottom to top. This membrane allows gas to enter and exit, but isolates liquid, ensuring the purity of hydrogen and other substances, and can also prevent liquid from splashing, ensuring the dryness of the outside of the equipment.
