Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

As mentioned in the background section, CN 204134742U presents a technical problem, the present application proposes a cathode insulation box, which is improved on the basis of this prior art. Fig. 1 shows a schematic cross-sectional front view of a cathode insulation can according to an embodiment of the present application, and fig. 2 shows a schematic cross-sectional side view of the cathode insulation can of fig. 1. The present application is an improvement of the cathode insulation box of the prior art, the basic principle of the insulation box is well known, and the parts which are not described in detail in the present application can be fully understood by those skilled in the art.

As shown in the drawings, the cathode insulating box of the present application also includes a box body 10, a wire hanging opening 102 for the cathode wire 2 to pass through is formed in the center of the bottom of the box body 10, and a quartz sleeve 104 for supporting the cathode wire 2 is formed upward in the bottom of the box body 10. Different from the prior art, in the present application, the top of the box 10 is provided with a detachable sealing upper cover 11, the bottom of the box 10 is provided with a detachable base 12, the upper opening of the quartz sleeve 104 is provided with a sealing cover plate 1041, and the lower opening of the quartz sleeve 104 is provided with a sealing element at the position contacting with the base 12. In the illustrated embodiment, the upper sealing cover 11 is detachably connected to the box 10 by a plurality of bolts around the upper sealing cover 11, two handles 111 are disposed above the upper sealing cover 11 for operation, and a sealing member is disposed between the upper sealing cover 11 and the box 10.

The improvement of the relative prior art of this application lies in, and this application is through setting up quartz sleeve's last end opening and the box is inside isolated for the box that originally has hot-blast mouthful is sealed isolated for the suspension wire mouth of below, and it is inside upwards to invade the box wet heat steam through the suspension wire mouth among the prior art can't get into the box, thereby has avoided the inside erosion that receives wet heat steam of box, has improved the life of cathode insulation case.

The case 104 and the base 12 are coupled to each other by a bolt structure. The bottom of the box 104 is connected to the base 12 at a position that is separated from other structures of the wet electric dust collector by the base 12, so that a sealing structure between the bottom of the box 104 and the base 12 is not needed. In addition, the electric heater to be mentioned later can release moisture in the box body conveniently without a sealing structure.

Further, similar to the prior art, in one embodiment, an anti-wind pipe 103 may also extend from the messenger opening 102 to below the bottom of the housing 10, and a quartz sleeve 104 may be disposed to cover the anti-wind pipe 103.

Further, a sealing member is disposed between the sealing cover plate 1041 and the quartz sleeve 104. It can be seen that the sealing cover plate 1041 of the present application has only one hole for connecting the cathode wire 2, and of course, in order to prevent moisture from passing through, the hole for connecting the cathode wire 2 with the sealing cover plate 1041 is also provided with a sealing gasket or the like to prevent moisture from entering the box body through the hole. The prior art cover plates also have other hot air holes through which hot air is blown to remove moisture, and the sealed cover plate of this embodiment eliminates these hot air holes and thus eliminates the need for hot air ports in the top of the enclosure 10.

In addition, in the illustrated embodiment, the sealing cover plate 1041 is pressed above the quartz sleeve 104 by the sagging tension of the cathode wire 2, and the sagging tension of the cathode wire 2 is large enough to ensure that the sealing cover plate 1041 is tightly pressed against the sealing member above the quartz sleeve 104. Similarly, the position where the lower opening of the quartz sleeve 104 contacts the base 12 is pressed against the sealing member by the sagging tension of the cathode wire 2 and the weight of the quartz sleeve 104 itself.

Further, because of the problems of installation or structural deformation, it is not practical that no moisture enters the inside of the box 10 at all, and therefore, in a specific embodiment of the present application, two sets of electric heaters 107 and a temperature measuring sensor 200 are further disposed around the inside wall of the box 10 (fig. 1 shows four heating pipes of the two sets of electric heaters 107 in a cut-off manner for convenience of illustration, and fig. 2 shows only two heating pipes of one set of electric heaters 107 due to the problem of displaying the direction). In addition, since the upper portion of the chamber 10 is sealed, and a sealing structure is formed between the quartz sleeve 104 and the base 12, moisture intruding into the inside of the chamber 10 is baked by the electric heater 107 and can be released from the chamber 10 through a gap between the chamber 10 and the base 12 without the sealing structure.

In addition, in order to further improve the sealing and moisture-proof effect, in a specific embodiment of the present application, the inner and outer sidewalls of the box 10 are provided with thermal insulation layers.

It is to be understood by those skilled in the art that while the present invention has been described in terms of several embodiments, it is not intended that each embodiment cover a separate embodiment. The description is given for clearness of understanding only, and it is to be understood that all matters in the embodiments are to be interpreted as including all technical equivalents which are encompassed by the claims.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of the invention should be considered within the scope of the invention.
