Description

Technical Field

[0001] The invention relates to the field of fin electrodes, in particular to a fin electrode with a split bolt connection structure. Background Art

[0002] The fin electrodes of existing electrode boilers are of integral technology. Although such a structure saves assembly time, it causes great cost for later maintenance. Therefore, it is necessary to improve the fins of existing electrode boilers to save time and effort in maintenance and reduce costs. Summary of the invention

[0003] The object of the present invention is to provide a fin electrode with a split bolt connection structure to solve the problem that the fin electrode of the existing electrode boiler is an integral type and is therefore inconvenient to maintain.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A fin electrode with a split bolt connection structure comprises an electrode upper part, a bolt set and a fin electrode which are arranged in sequence from top to bottom, and the fin electrode is connected in a zero position barrel.

[0005] The fin electrode adopts a split structure, specifically, the upper part of the electrode and the fin electrode are separated, and the two parts are connected with a bolt kit. The advantage of this structure is that the split bolt structure can reduce both the equipment workload and the subsequent maintenance costs.

[0006] As a further preferred embodiment of the present invention, a coaxiality maintaining tool is provided between the fin electrode and the zero position barrel.

[0007] Due to technical requirements, various parts of the electrode boiler have high requirements for coaxiality during assembly, especially the coaxiality between the fin electrode and the zero position barrel, because the coaxiality between the fin electrode and the zero position barrel directly affects the safe operation of the electrode boiler. The existing assembly technology requires three workers and uses coils for correction. Such a project is time-consuming and labor-intensive, and the repeatability of the assembly results cannot be guaranteed. For this reason, in this solution, a coaxiality maintaining tooling is set in the zero position barrel. Relying on this tooling, two workers can achieve a good assembly effect, and the assembly time is effectively reduced, and the repeatability of the assembly results can be guaranteed.

[0008] As a further preferred embodiment of the present invention, the fin electrode includes a ceramic cylinder, a cable hole is provided in the middle of the ceramic cylinder, a cable is arranged in the cable hole, a fin plug-in groove is provided on the outer wall of the ceramic cylinder, a fin is plugged into the ceramic cylinder through the fin plug-in groove, a metal sheet is provided on the end surface of the fin close to the ceramic cylinder, and the fin is connected to the cable through a wire connected to the metal sheet.

[0009] The existing fin structure on the market is an integral one. If a single fin is corroded during later use, the fin must be replaced as a whole, which is not cost-effective for customers. In this solution, such a structure solves this problem and a single fin can be replaced.

[0010] As a further preferred embodiment of the present invention, the fin comprises a titanium alloy sheet and a 316 stainless steel sheet with graphene coated on the surface, and the 316 stainless steel sheet with graphene coated on the surface is clamped between two titanium alloy sheets.

[0011] According to investigation, the fin electrodes on the market are made of 316 stainless steel with graphene coated on the surface. This technology has very strict requirements on the integrity of the coating on the outer surface. During the actual assembly process, a large number of scratches are often generated on the electrode fins, which seriously affects the service life and normal operation of the electrode boiler. Here, the structure of the electrode fins is improved to a "sandwich" form. The materials on both sides are titanium alloy, and the material in the middle is 316 stainless steel. 304 stainless steel bolts are used for connection. This structure can effectively solve the problem of overall replacement of the fin electrode during later maintenance, and also solves the problem of scratches.

[0012] As a further preferred embodiment of the present invention, the titanium alloy sheet and the 316 stainless steel sheet with graphene plated on the surface are connected by bolts.

[0013] The bolts are 304 stainless steel bolts.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. The fin electrode adopts a split structure, specifically, the upper part of the electrode and the fin electrode are separated, and the two parts are connected by a bolt kit. The advantage of this structure is that the split bolt structure can reduce both the equipment workload and the subsequent maintenance costs.

[0015] 2. Due to technical requirements, various parts of the electrode boiler have high requirements for coaxiality during assembly, especially the coaxiality between the fin electrode and the zero position barrel. This is because the coaxiality between the fin electrode and the zero position barrel directly affects the safe operation of the electrode boiler. The existing assembly technology requires three workers and uses coils for correction. Such a project is time-consuming and labor-intensive, and the repeatability of the assembly results cannot be guaranteed. For this reason, a coaxiality maintaining tool is set in the zero position barrel in this solution. Relying on this tool, two workers can achieve a good assembly effect, and the assembly time is effectively reduced, which can also ensure the repeatability of the assembly results.

[0016] 3. The existing fin electrode structure on the market is not integrated. If corrosion occurs on a single fin during later use, the fin must be replaced as a whole, which is not cost-effective for customers. In this solution, such a structure solves this problem and allows the replacement of a single fin.

[0017] 4. According to investigation, the fin electrodes on the market are made of 316 stainless steel with graphene on the surface. This technology has very strict requirements on the integrity of the coating on the outer surface. In the actual assembly process, a large number of scratches are often generated on the electrode fins, which seriously affects the service life and normal operation of the electrode boiler. Here, the structure of the electrode fins is improved to a "sandwich bread" form. The materials on both sides are titanium alloy, and the material in the middle is 316 stainless steel. 304 stainless steel bolts are used for connection. This structure can effectively solve the problem of overall replacement of fin electrodes during later maintenance, and also solves the problem of scratches. BRIEF DESCRIPTION OF THE DRAWINGS
