Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of electrolytic equipment, in particular to a wind cover for an electrolytic cell. BACKGROUND
[0002] An electrolytic cell is composed of a cell body, an anode and a cathode, and most of them are separated by a diaphragm. According to the different electrolyte, it is divided into three types of water solution electrolytic cell, molten salt electrolytic cell and non-aqueous solution electrolytic cell. When direct current passes through the electrolytic cell, oxidation reaction occurs at the interface between the anode and the solution, and reduction reaction occurs at the interface between the cathode and the solution to produce the desired product. In the process of electrolysis, due to electrolysis, high temperature and other factors, acid mist will be produced and volatilized in the electrolytic cell. The traditional wind cover is a long groove which is inverted and buckled on the electrolytic cell to cover the entire electrolytic cell including the conductive copper bar. The acid mist produced during electrolysis volatilizes and falls on the electrolytic copper bar to corrode the conductive copper bar, thereby causing damage to the electrolytic copper bar and reducing the electrolysis efficiency.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0023] In view of the above problems, the present application provides a wind cover for an electrolytic cell, and the technical scheme of the present application is described in detail below in combination with the drawings.
[0024] As shown in Figure 1 and Figure 2 A wind cover for an electrolytic cell, comprising a wind cover body 4; the wind cover body 4 of the present application is provided with an arc-shaped cover or a horizontal cover in a lifting cover manner at the top, and symmetrical and parallel vertical plates are connected on both sides of the cover body, and the whole is a cover matching the length of the electrolytic cell 1; an inclined plate 41 is connected at the bottom of the vertical plate on both sides of the wind cover body 4, and the inclined plate 41 has an acute angle with the vertical plate, and the angle of the acute angle is between 30 degrees and 60 degrees, and the best choice is 45 degrees. When the volatilized gas condenses and falls on the wind cover body 4, it flows back to the electrolytic cell along the inclined plate 41. Since the electrode plate 3 in the electrolytic cell 1 is located above the copper bar 2 during normal operation, gaps will inevitably occur. In order to reduce these gaps as much as possible, a soft plate 43 is connected at the bottom of the plate along the inclined plate 41, and the soft plate 43 is parallel to the vertical plate to block these gaps.
[0025] In this way, the present application sets an inclined plate 41 as a flow guide plate at the bottom of the traditional wind cover to guide the condensed solution that originally falls on the copper bar 2 into the electrolytic cell 1, and at the same time blocks the electrode plate 3 through the soft plate 43, thereby reducing the acid mist generated during electrolysis from falling on the electrolytic copper bar and corroding the conductive copper bar, thereby reducing the service life of the electrolytic copper bar and the electrolysis efficiency.
[0026] In the device, the electrode plates 3 are arranged in the electrolytic tank 1 in a plurality of intervals, and the liquid collection on the inclined plate 41 will inevitably flow to the copper bar 2 after falling on the electrode plates 3. Therefore, a semicircular liquid collection groove 46 is arranged at the plate edge of the inclined plate 41, and a plurality of drainage heads 44 are arranged at the radial groove edge of the liquid collection groove 46 in intervals. The drainage head 44 is a groove type and is in communication with the groove bottom of the liquid collection groove 46 to drain the liquid. At the same time, the interval between the two drainage heads 44 is the interval of the electrode plates 3 in the electrolytic tank 1, and the drainage head 44 is located between the two electrode plates 3. In this way, the liquid collection can be guided as much as possible to avoid falling on the electrode plates 3.
[0027] In the device, the electrolytic tank 1 is relatively long, and in order to avoid the collapse of the inclined plate 41, the bottom of the inclined plate 41 is provided with a connecting column 42 connected with the vertical plate for support.
[0028] In the device, the soft plate 43 naturally falls vertically above the electrode plate 3 and has a gap of 0.5-1 cm with the electrode plate 3 to avoid contact with the electrode plate 3. At the same time, the soft plate 43 is located at the inner side groove edge of the electrolytic tank 1 to prevent the condensed volatile solution from falling on the copper bar of the groove edge.
[0029] In the device, the outer side of the fan cover body 4 is provided with a positioning plate 45 flush with the outer side of the groove edge of the electrolytic tank 1 to facilitate positioning when covering.
[0030] Finally, it should be noted that in this text, the relationship such as first and second belongs to only distinguish one entity or operation from another entity or operation, and does not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the term includes, contains or any other variant is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such process, method, article or equipment.
