Description

Technical Field

[0001] The utility model relates to the technical field of reaction tanks, in particular to a water electrolysis hydrogen production reaction tank. Background Art

[0002] Hydrogen production by water electrolysis is a relatively convenient method of producing hydrogen. Direct current is passed into an electrolytic cell filled with electrolyte, and water molecules undergo electrochemical reactions on the electrodes, decomposing into hydrogen and oxygen. In some production workshops, hydrogen production tanks are directly placed on the ground, because the interior of the reaction tank is made of glass. Workers may collide with the tank during work in the workshop, or the pressure inside the tank is too high, causing the glass to break and causing the storage tank to explode, which poses a huge safety hazard.

[0003] A Chinese patent document CN216614867U discloses a novel reaction tank for producing hydrogen by alkaline water electrolysis, comprising a workbench, an inner tank, which is fixedly connected to the workbench, and the inner tank is used to store electrolytic liquid; a first protective shell; a second protective shell is located outside the inner tank, and the first protective shell and the second protective shell are closed to wrap the inner tank; a supporting device, which is movably connected to the first protective shell, and the supporting device is used to fit and support the inner tank, and supporting devices with equal spacing are arranged inside the protective shell, and the vibration from the outside of the protective shell is buffered by the internal elastic member, and the inner tank is heated by the heating copper wire arranged inside the supporting device, so as to accelerate the volatilization of the decomposed water inside, thereby increasing the efficiency and quality of the decomposition of the device;

[0004] However, the reaction tank cannot see the reaction status inside the tank in time, and the protective shell needs to be opened for inspection. This process is rather troublesome, and the tank is easily collided during opening and closing, posing a safety hazard; the position layout of the electrode rods in the tank also needs to be further optimized and improved.

[0005] Therefore, we provide a water electrolysis hydrogen production reaction tank, the exterior of the tank is made of metal, which is anti-collision and anti-breakage. The metal tank is covered with a heating cover to heat the glass liner and accelerate the volatilization of the internal electrolyte. The limit assembly facilitates the disassembly and assembly of the electrode rod in the tank, avoiding the situation where the electrode rod is rigidly connected to the tank for sampling and is difficult to disassemble, inspect and replace. Utility Model Content

[0006] In order to solve the above-mentioned problems existing in the prior art, the utility model provides a water electrolysis hydrogen production reaction tank, which can heat the glass inner tank to accelerate the volatilization of the internal electrolyte; the limit assembly is used to facilitate the disassembly and assembly of the electrode rod in the tank body, avoiding the situation where the electrode rod is rigidly connected to the tank body for sampling and is difficult to disassemble, inspect and replace.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A water electrolysis hydrogen production reaction tank comprises a tank body, on which a heating assembly and a limiting assembly are arranged, the heating assembly comprises a heating cover arranged on the periphery of the tank body, the limiting assembly comprises a plurality of limiting roller groups and a positive electrode plate and a negative electrode plate arranged inside the tank body, the positive electrode plate and the negative electrode plate are electrically connected to a frame, the heating assembly heats and keeps the electrolyte in the tank body warm through the heating cover, and the limiting assembly limits the frame through the limiting roller group.

[0009] Furthermore, two groups of the limiting roller groups are provided, and the two groups of the limiting roller groups are symmetrically installed inside the tank body. The limiting roller group consists of two rollers, and there is a gap between the two rollers that can accommodate the thickness of the frame.

[0010] Furthermore, the positive electrode plate is located below one group of the limiting roller groups, and the negative electrode plate is located below the other group of the limiting roller groups. The sealing cover is opened, and one end of the frame equipped with the electrode rod is aligned with the gap of the limiting roller group and then lowered until one end of the frame is seated on the positive electrode plate and the negative electrode plate. The positive electrode plate and the negative electrode plate support the frame while being electrically connected to it. The limiting roller group limits the other end of the frame to prevent it from deviating from its position in the tank body.

[0011] Furthermore, one end of the frame is placed on the positive electrode plate and the negative electrode plate, and the other end of the frame is located between the limiting roller groups, and the frame is slidably connected to the limiting roller groups.

[0012] Furthermore, a plurality of electrode rods are evenly spaced on the frame, and the plurality of electrode rods are electrically connected to the frame. The evenly spaced electrode rods can better contact the electrolyte in the tank body. Compared with the traditional simple double-tube contact, the reaction tank improves the efficiency of hydrogen production by electrolysis.

[0013] Furthermore, an electric heating tube is arranged in the heating cover, an explosion-proof glass window is arranged on the tank body, and the heating cover is provided with a notch corresponding to the explosion-proof glass window. The explosion-proof glass window facilitates the operator to observe the reaction status inside the tank body in real time.

[0014] Furthermore, the positive plate is connected to a positive terminal, the negative plate is connected to a negative terminal, a sealing cover is hinged on the tank body, the setting of the sealing cover facilitates the operator to disassemble and assemble the frame, the sealing cover is provided with an air outlet, the tank body is provided with a liquid drain port, and the tank body is connected to a bracket.

[0015] The beneficial effects of the utility model are:

[0016] 1. Open the sealing cover, align one end of the frame with the electrode rods with the gap of the limiting roller group and then lower it until one end of the frame is located on the positive plate and the negative plate. The positive plate and the negative plate support the frame while being electrically connected to it. The limiting roller group limits the other end of the frame to prevent it from deviating from its position in the tank body. The electrode rods distributed at equal intervals can better contact the electrolyte in the tank body. Compared with the traditional simple double-tube contact, this reaction tank improves the efficiency of hydrogen production by electrolysis.

[0017] 2. By setting the sealing cover and the limit assembly, the electrode rod is electrically connected to the positive and negative plates through the frame, without the need for hard soldering connection operations, and it is easy to place or remove the frame, thereby achieving the effect of portable disassembly and maintenance of the electrode rod.

[0018] 3. By adding a heating component to the outside of the tank, the glass inner tank can be heated in a surrounding multi-directional manner through the annular electric heating tubes in the heating component, thereby accelerating the volatilization of the electrolyte inside the tank and improving the hydrogen production efficiency of the reaction tank.
