Description

Calandria type water-cooling flue

Technical Field

The utility model relates to a water-cooling flue for smelting furnace especially relates to calandria formula water-cooling flue.

Background

In copper processing and steel mill enterprises, a coreless smelting furnace (electric furnace) is indispensable equipment, and the coreless smelting furnace has a tilting type and a subsurface type, wherein the tilting type smelting furnace is a furnace body which is tilted for a certain angle to transfer the solution in the furnace into a casting machine. The tipping coreless electric furnace adds scrap materials from the top of the furnace through a vibration feeding device and adds block materials through a feeding trolley. The flue gas temperature that produces in the reinforced is very high, can reach more than 1000 degrees, therefore the flue that gathers dust must be the water-cooling flue, can prevent on the one hand that the flue from being heated and warp, and on the other hand can reduce the temperature of flue gas, prevents that the flue gas from damaging the sack that gathers dust. The more the flue gas circuitously in the water-cooling flue, the more the temperature is reduced. For example, chinese patent publication No. CN108204738A discloses a water sealing structure of a movable flue of a novel movable rotary kiln, wherein a kiln ceiling is arranged above the kiln in an operation channel, and a flue is fixedly arranged below the kiln ceiling; the inner sides of the lower ends of the two side surfaces of the flue are respectively provided with a track, a bottom plate is positioned above the track, and two rollers pivoted on the bottom surface of the bottom plate are respectively supported on the track in a rolling way; the bottom plate is fixedly connected with the kiln, and a tuyere arranged on the bottom plate is communicated with a tuyere arranged on the kiln through an air duct; the lower extreme of two inboards of flue still sets firmly a opening basin up respectively, and the both ends of bottom plate extend downwards and insert in the basin. The structure is complex and the manufacturing cost is high.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that current water-cooling flue cooling effect is not good, perhaps the structure is complicated, and the cost of manufacture is high, provides a calandria formula water-cooling flue for this reason.

The technical scheme of the utility model is that: the calandria type water-cooling flue includes: a 90-degree water-cooling flue; the S-shaped water-cooling flue is sleeved in the 90-degree water-cooling flue, and a gap is reserved between the S-shaped water-cooling flue and the 90-degree water-cooling flue; refractory cotton filled in a gap between the S-shaped water cooling flue and the 90-degree water cooling flue; the refractory cotton rear baffle is fixedly connected in the 90-degree water-cooling flue and is in contact with the refractory cotton and the end surface of the S-shaped water-cooling flue; the front baffle plate is fixedly connected outside the 90-degree water-cooling flue, and the free end of the front baffle plate is in contact with the end face of the refractory cotton.

In the scheme, the S-shaped water-cooling flue is fixed on the electric furnace through the support.

In the scheme, the refractory cotton front baffle is fixedly connected outside the 90-degree water-cooling flue through bolts.

In the scheme, the 90-degree water-cooling flue is fixed on the ground through the support.

In the scheme, the 90-degree water-cooling flue is fixedly connected with a flue fixing plate.

The beneficial effects of the utility model are that the water-cooling flue has S type flue and 90 degrees flues, and the flue gas realizes circuitous many times in the flue, and the flue gas temperature reduces more. The S-shaped flue is fixed on the furnace body, is movable and is inserted into the 90-degree flue to realize dynamic sealing; the refractory cotton ensures good sealing, air is not sucked in, and the negative pressure is not reduced. And a refractory cotton front baffle and a refractory cotton rear baffle are arranged on the two water-cooling flues to prevent the refractory cotton from being sucked into and separated from the water-cooling flues.

Drawings

FIG. 1 is a schematic view of the present invention;

FIG. 2 is a partial enlarged view of FIG. 1 at B;

FIG. 3 is a cross-sectional view A-A of FIG. 1;

in the figure, a water-cooling flue with the angle of 1 and 90 degrees, a water-cooling flue with the angle of 2 and S-shaped, a refractory cotton rear baffle, a refractory cotton front baffle, a support 7, a support, and a flue fixing plate are arranged in the flue.

Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments of the ordinary skilled person in the art without creative work belong to the protection scope of the present invention.
