Abstract
The utility model discloses a pulverized coal combustion furnace for ceramic tile spray drying, including pulverized coal combustion furnace main part, lower ash pipe and water seal, its characterized in that: a fire grate made of steel bars is additionally arranged between a lower ash pipe and a water seal at the bottom of a main body of the pulverized coal combustion furnace, a movable upper baffle plate is arranged above the fire grate, and a movable lower baffle plate is arranged below the fire grate. The utility model discloses when normal production and clearance cinder, cut off cinder whereabouts passageway by lower plate washer or last plate washer respectively, avoid during the high temperature cinder accident fell into the water seal to prevent to scald the operative employee because of exploding hot water hot slag of stove to splash everywhere, play the safety protection effect.
Description
Technical Field
The utility model relates to a production of ceramic brick especially relates to a pulverized coal combustion furnace for ceramic brick spray drying.
Background
In the process of ceramic production, the ground slurry is dried to form powder particles, and the slurry is dried by a spray tower in the process. The hot air required by the spray tower for drying is usually provided by fire coal of a grate-fired furnace, a coal water slurry furnace and a pulverized coal combustion furnace. During the combustion process of the pulverized coal combustion furnace, the coal slag can be adhered to the wall of the pulverized coal combustion furnace and the wall of the hot blast pipe. When the coal slag is slagging to a certain lumpiness, the coal slag can fall into a water seal below the pulverized coal combustion furnace. Because the temperature of the coal cinder is nearly thousands of degrees and the adhesion is not very tight, after the large coal cinder falls into the water seal, water is rapidly gasified, so that water vapor, water and coal cinder are splashed all around, hot water hot slag splashes all around to scald operators, the water vapor and water splashed into the combustion furnace can also cause the temperature in the combustion furnace to be rapidly reduced, and all the conditions can cause safety accidents, and the condition is called as a frying furnace in the application.
Disclosure of Invention
The utility model aims at providing a coal dust fires burning furnace for pottery brick spray drying can effectively prevent the cinder from falling into the fried stove that water seal back and arouse.
The utility model adopts the technical proposal that: the utility model provides a pulverized coal fires burning furnace for ceramic brick spray drying, includes pulverized coal fires burning furnace main part, lower ash pipe and water seal, its characterized in that: a fire grate made of steel bars is additionally arranged between a lower ash pipe and a water seal at the bottom of a main body of the pulverized coal combustion furnace, a movable upper baffle plate is arranged above the fire grate, and a movable lower baffle plate is arranged below the fire grate.
The height between lower plate washer and the grate is 100~300mm, and the height of going up plate washer and grate is 50~60 mm.
The utility model discloses when normal production and clearance cinder, cut off cinder whereabouts passageway by lower plate washer or last plate washer respectively, avoid during the high temperature cinder accident fell into the water seal to prevent to scald the operative employee because of exploding hot water hot slag of stove to splash everywhere, play the safety protection effect.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic view of the present invention in normal production;
FIG. 2 is a schematic structural view of the utility model when cleaning coal cinder;
in the figure, 1 is a main body of a pulverized coal combustion furnace, 2 is a lower ash pipe, 3 is a water seal, 4 is a fire grate, 5 is an upper baffle plate, and 6 is a lower baffle plate.
Detailed Description
For a better understanding and an enabling description of the present invention, reference will now be made to the following examples.
As shown in fig. 1, the utility model relates to a pulverized coal combustion furnace for spray drying of ceramic tiles, which comprises a pulverized coal combustion furnace main body 1, a lower ash pipe 2 and a water seal 3, wherein a grate 4 made of steel bars is additionally arranged between the lower ash pipe and the water seal of the pulverized coal combustion furnace main body, and movable baffles are arranged above and below the grate; the upper baffle 5 and the lower baffle 6 are made of common heat-resistant materials. The height difference between the lower baffle plate and the grate is 100-300 mm, and a cinder storage cooling space is formed between the lower baffle plate and the grate; the height difference between the upper baffle plate and the grate is 50-60 mm, so that the grate is convenient to push in.
The utility model discloses a working process specifically does:
during normal production, the upper baffle plate is pulled out and the lower baffle plate is pushed into the ash discharging pipe, so that coal cinder falls on the lower baffle plate 3 for storage and cooling when falling down, and large coal cinder can be broken into small blocks after passing through the fire grate 1, as shown in figure 1. When the coal cinder is cleaned, the upper baffle plate 2 is pushed into the lower ash pipe to block a coal cinder falling channel and block coal cinder falling during cinder cleaning, so that the phenomenon that the coal cinder directly falls into the water seal 4 to generate a blast furnace and affect production and safety is avoided, in addition, the upper baffle plate smashes large coal cinder on a grate, then the lower baffle plate is pulled open, and small coal cinder after cooling falls into the water seal; after the coal cinder is cleaned, the lower baffle plate is pushed in, the upper baffle plate is pulled out, and the position returns to the original position, as shown in figure 2.
The utility model discloses when normal production and clearance cinder, cut off cinder whereabouts passageway by lower plate washer or last plate washer respectively, avoid during the high temperature cinder accident fell into the water seal to prevent to scald the operative employee because of exploding hot water hot slag of stove to splash everywhere, play the safety protection effect.
The embodiments of the present invention are only descriptions of the preferred embodiments of the present invention, not right the present invention is designed and limited, without departing from the design concept of the present invention, the technical personnel in the field should fall into the protection scope of the present invention for various modifications and improvements made by the technical solution of the present invention, and the technical contents of the present invention are all recorded in the claims.
