Description
Technical Field
The utility model belongs to carbide stove part, concretely relates to carbide stove burner.
Background
And at a furnace outlet of a first layer of the calcium carbide furnace, the molten high-temperature calcium carbide flows into the calcium carbide pot through a furnace nozzle, and is conveyed to a cold bag room through the molten calcium carbide through the calcium carbide pot, the trolley and the rail for cooling. At this in-process, the molten high temperature carbide that is mingled with the molten iron flows through the furnace mouth, is provided with the water route in the furnace mouth and cools down, if the water route blocks up, then the furnace mouth can be burnt out to high temperature carbide flow, and the carbide meets water and can take place the flash explosion, and the safety risk is big.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a carbide stove burner has cancelled the water route that current burner used, has improved high temperature resistant intensity, does not need the maintenance of often blowing out to can effectively improve production efficiency.
The technical scheme is as follows:
carbide stove burner includes: a furnace mouth body and a refractory injection material; the furnace nozzle body includes: the fire-resistant pouring trough comprises a connecting section and a flow trough section, wherein the end parts of the connecting section and the flow trough section are connected, the connecting section and the flow trough section are of arc-shaped trough body structures, a plurality of cross-connected transverse partition plates and longitudinal partition plates are arranged on the inner wall of the flow trough section, and a fire-resistant pouring material covers the upper surface of the flow trough section.
Further, the chute section is provided with an arc edge at the front end, and an arc block is arranged on the inner wall of the chute section at the inner side of the arc edge.
Furthermore, the heights of the upper surfaces of the connecting positions of the transverse partition plates and the longitudinal partition plates are the same.
Furthermore, the included angle of the axes of the connecting section and the runner section is 90-180 degrees.
Furthermore, the inner wall surface of the runner section is divided into a plurality of separated spaces by the transverse partition plates and the longitudinal partition plates, and the transverse partition plates and the longitudinal partition plates are embedded in the refractory casting material.
Furthermore, the shape of the transverse partition plate is crescent.
Compared with the prior art, the utility model have following advantage:
the utility model redesigns the furnace mouth structure, cancels the water path used by the prior furnace mouth, because the utility model discloses difficult burning loss, the burning-through furnace mouth phenomenon obviously reduces, has improved high temperature resistance intensity moreover.
Because the utility model is not easy to burn, the furnace does not need to be frequently shut down for maintenance, thereby improving the production efficiency and obviously reducing the danger coefficient.

Detailed Description
The following description fully illustrates the specific embodiments of the invention to enable one skilled in the art to practice and reproduce.
As shown in figure 1, is a schematic structural view of the furnace mouth of the calcium carbide furnace of the utility model. As shown in fig. 2, it is a schematic structural diagram of the middle burner body 1 of the present invention. As shown in FIG. 3, it is a schematic diagram of the structure of the vertical section of the furnace mouth of the middle calcium carbide furnace of the present invention.
Carbide stove burner, its structure includes: a furnace mouth body 1 and a refractory injection material 2.
The furnace nozzle body 1 includes: the connecting section 11 and the chute section 12 are connected, the ends of the connecting section 11 and the chute section 12 are connected, and the included angle of the axes is 90-180 degrees. The connection section 11 and the chute section 12 are of an arc-shaped groove structure. Refractory charge 2 covers the upper surface of the launder section 12
The inner wall of the runner section 12 is provided with a plurality of transverse clapboards 121 and longitudinal clapboards 122, the transverse clapboards 121 and the longitudinal clapboards 122 are connected in a cross way, and the transverse clapboards 121 are crescent. The height of the connecting position of the transverse partition 121 and the longitudinal partition 122 is the same. Thus, the inner wall surfaces of the runner sections 12 are partitioned by the transverse partition plates 121 and the longitudinal partition plates 122 to form a plurality of partitioned spaces, so that the refractory castable 2 can be conveniently embedded. The thickness of the runner section 12 gradually decreases, and the depth of the inner wall surface gradually decreases.
The front end part of the runner section 12 is provided with an arc-shaped edge 123, and the inner wall of the runner section 12 at the inner side of the arc-shaped edge 123 is provided with an arc-shaped block 124; the curved inner edge 123 and the curved blocks 124 serve to improve the structural strength of the front end of the launder section 12.
After the refractory pouring material 2 is coated on the upper surface of the furnace mouth body 1, the refractory pouring material 2 is poured into the separation space, the transverse partition plate 121 and the longitudinal partition plate 122 are embedded in the refractory pouring material 2, the inner wall surface of the separation space can improve the bonding force of the refractory pouring material 2, the refractory pouring material 2 is prevented from falling off, and the refractory pouring material 2 is a high-temperature-resistant refractory material.
During the use, bury connecting segment 11 in the tapping hole position of carbide stove one deck underground, the melting carbide liquation flows through from fire-resistant notes material 2 from furnace comes out the back, avoids melting carbide liquation direct contact furnace mouth body 1, and furnace mouth body 1 adopts cast iron casting preparation moreover, and furnace mouth body 1 is difficult to be burnt and is lost.
The carbide furnace mouth has changed original furnace mouth structure completely, has cancelled the inside water route that is used for the cooling of original furnace mouth, is difficult for being burnt and decreases to reduce the danger coefficient.
The terminology used herein is for the purpose of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
