Description
Technical Field
[0001] The utility model relates to the technical field of sodium hypochlorite generators, in particular to an automatic descaling device for an electrolytic cell of a sodium hypochlorite generator. Background Art
[0002] The electrolytic cell is one of the important components in the sodium hypochlorite generator. In the patent document with application number CN202221917778.5, it discloses "a sodium hypochlorite generator electrolytic cell with descaling function", which has the advantages of "avoiding the generation of dirt inside the electrolytic cell body and facilitating the replacement of the filter element" when used. However, there are still some defects:
[0003] The filter element needs to be replaced every certain period of time during use, and the replacement frequency is relatively high. This is not only time-consuming and labor-intensive, but also increases the cost of using the filter element and the cost of descaling the electrolytic cell. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide an automatic descaling device for an electrolytic cell of a sodium hypochlorite generator. When in use, the filter screen does not need to be replaced, and only the filter residue in the residue collecting box needs to be cleaned regularly. The cleaning frequency is lower than the existing frequency of replacing the filter element, which not only saves time and effort, but also reduces the cost of descaling the electrolytic cell.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:
[0006] An automatic descaling device for an electrolytic cell of a sodium hypochlorite generator comprises an electrolytic cell body, wherein a liquid inlet pipe is arranged on the top of the electrolytic cell body, a liquid discharge pipe is arranged on the bottom, and the electrolytic cell body further comprises a filter screen, a slag collecting box and a box cover; the filter screen is arranged in the liquid inlet pipe and is inclined downward from the left, a slag outlet is reserved on the right side of the liquid inlet pipe corresponding to the filter screen, a side projection of the filter screen completely overlaps with the slag outlet, a slag collecting box is fixed on the right side of the liquid inlet pipe, the slag collecting box is a cylindrical structure adapted to the shape of the slag outlet, and the right port is sealed by the box cover.
[0007] As an improvement, the box cover is a square cover structure, and after the bottom is hinged to the bottom of the slag collecting box, the top and the slag collecting box are fixed together by a fastening structure.
[0008] As an improvement, the fastening structure includes ear plate 1, ear plate 2, handle screw and knob nut; the flip side of the box cover is integrally formed with ear plate 1, and the top of the slag collecting box is integrally formed with ear plate 2 corresponding to ear plate 1, and the threaded rod of the handle screw passes through ear plate 1 and ear plate 2 at the same time, and then the ear plate 1 and ear plate 2 are fixed together by cooperating with the knob nut, so as to facilitate the box cover to be firmly sealed on the slag collecting box.
[0009] As an improvement, a sealing ring is fixed on the inner wall of the box cover, which contacts the right end surface of the slag collecting box, so as to ensure good sealing performance at the connection between the slag collecting box and the box cover.
[0010] The advantages of the utility model compared with the prior art are:
[0011] When the utility model is in use, during the process that liquid enters the electrolytic cell body through the liquid inlet pipe, the filter screen can filter the liquid and flush the filter residue into the residue collecting box. When a lot of filter residue is accumulated in the residue collecting box, the cover is opened and the filter residue is cleaned out. At the same time, a lot of filter residue can be stored in the residue collecting box at one time. Therefore, the frequency of cleaning the filter residue of the utility model is lower than the frequency of replacing the filter element in the prior art. At the same time, not replacing the filter screen also increases the cost of using the filter element and the cost of descaling the electrolytic cell. BRIEF DESCRIPTION OF THE DRAWINGS
