Description

Technical Field

[0001] The present application relates to the field of firing furnaces, and in particular to a firing furnace for producing refractory bricks. Background Art

[0002] Refractory bricks are special bricks that can maintain structural stability and chemical stability for a long time in high temperature environments. They are commonly used in various industrial equipment and facilities. In the production of refractory bricks, sintering is a very critical step, which helps to fix the structure and physical properties of the bricks.

[0003] In the prior art, such as the Chinese publication number CN219347294U, the utility model discloses a refractory brick firing furnace, including a furnace body, a filter box and a trolley, a plurality of smoke inlet pipes are symmetrically installed on both sides of the top surface of the furnace body, and the top of the smoke inlet pipe is fixedly connected to the inner cavity of the filter box, one side of the filter box is fixedly connected to one end of an exhaust pipe, and the other end of the exhaust pipe is connected to a fan, and the fan outlet is connected to one end of an air supply pipe, and the other end of the air supply pipe is connected to the inner cavity of the furnace body, a mounting plate is fixedly installed in the center of the top surface of the trolley, and a plurality of placement plates are symmetrically fixedly installed on the sides of the mounting plate, an air-uniform cavity is provided in the inner cavity of the mounting plate, and a plurality of hot air nozzles installed on the sides of the mounting plate are symmetrically connected on both sides of the air-uniform cavity, and an air inlet pipe is connected to one side of the air-uniform cavity. Beneficial effect: The utility model can reduce the firing temperature difference of the refractory brick blanks placed on the inner and outer sides of the placement plate, improve the heating uniformity of the refractory brick blanks, and is beneficial to improving the overall firing quality of the refractory bricks.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that when the refractory bricks are sintered in the firing furnace, the position of the refractory bricks is not fixed. When taking them out or putting them into the firing furnace, the bricks may fall off. Especially under high temperature conditions, the bricks expand due to heat and move, resulting in a decrease in product quality. In addition, smoke is generated when the bricks are sintered in the firing furnace. Some of the smoke is not treated and is directly discharged to affect the environment. At the same time, workers inhale the smoke, and the harmful substances in the smoke have an impact on the workers. Utility Model Content

[0005] The present application provides a firing furnace for the production of refractory bricks. When the refractory bricks are sintered, the bricks are fixed to prevent the bricks from falling when they are put into or taken out of the firing furnace. At the same time, it can also ensure that the bricks maintain a stable position during the entire sintering process. When the bricks are sintered, the smoke generated is treated before being discharged, thereby reducing pollution to the environment and reducing the concentration of harmful gases in the working environment.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a firing furnace for producing refractory bricks, the firing furnace comprising:

[0007] Furnace body;

[0008] A combustion chamber is arranged on the inner wall of the furnace body, and two sliding blocks are slidably arranged on both sides of the combustion chamber, and the two sliding blocks can slide;

[0009] A placing rack is fixedly arranged on one side opposite to the two sliders, and a plurality of connecting plates are fixedly arranged on one side of the slider, and the refractory bricks to be sintered are placed on the placing rack;

[0010] A plurality of vertical poles are respectively fixedly arranged on one side of the plurality of connecting plates, and a pressure plate is movably sleeved on the outer surfaces of the plurality of vertical poles, and the pressure plate can slide on the outer surfaces of the plurality of vertical poles;

[0011] A plurality of circular plates are fixedly arranged on one side of the plurality of vertical poles, and a spring is fixedly arranged on one side of the plurality of circular plates close to the pressing plate. The elastic force generated by the plurality of springs squeezes the pressing plate, further enabling the pressing plate to clamp the bricks to be sintered, thereby limiting the position of the bricks.

[0012] A handle is fixedly arranged on one side of the pressing plate, and the pressing plate is driven to move upward by pulling the handle upward.

[0013] As a further improvement scheme of the present application: a sealing cover is provided on one side of the furnace body, a pull plate is fixedly provided on the side of the placement rack close to the sealing cover, the multiple springs are movably sleeved on the outer surfaces of the multiple vertical poles, and the pull plate facilitates pulling the placement rack.

[0014] As a further improvement scheme of the present application: a first pipe is installed on one side of the furnace body, and an air pump is installed on one end of the first pipe. When the air pump is turned on, suction is generated at the air inlet end of the air pump, so that the smoke generated by sintering inside the furnace body comes into the inside of the second pipe.

[0015] As a further improvement of the present application: a second pipeline is provided at the outlet end of the air pump, and a processing pipeline is provided on one side of the second pipeline through a flange, which passes through the first pipeline to the interior of the second pipeline and is further discharged into the interior of the stirring plate.

[0016] As a further improvement scheme of the present application: a rotating rod is provided on one side of the inner wall of the processing pipe through a bearing, and a turbine blade is fixedly provided on the side of the rotating rod close to the second pipe. When discharged into the interior of the stirring plate, it will pass through the turbine blade, further causing the turbine blade to rotate.

[0017] As a further improvement of the present application: a plurality of stirring plates are fixedly provided on the outer surface of the rotating rod, and a leakage plate is provided on the outer surface of the rotating rod through a bearing. The plurality of stirring plates rotate to stir the activated carbon inside the treatment pipeline so that it is in full contact with the flue gas, and the leakage plate can rotate because of the bearing.

[0018] As a further improvement scheme of the present application: a sliding cover is provided on the outer surface of the treatment pipe, and a plurality of air outlets are opened on one side of the treatment pipe. The adsorptive material activated carbon is poured into the inside of the stirring plate by sliding the sliding cover, and the treated flue gas is discharged through the plurality of air outlets.

[0019] As a further improvement of the present application: slide grooves are provided on both sides of the inner wall of the combustion chamber, and two sliding blocks can slide in the slide grooves on both sides of the combustion chamber respectively.

[0020] Compared with the prior art, the advantages and positive effects of this application are:

[0021] 1. In the present application, when the furnace body is sintering refractory bricks, the sealing cover is opened, and the two sliders can slide in the slide grooves on both sides of the combustion chamber respectively. The placement rack is pulled by the pull plate, and the pressure plate can slide on the outer surfaces of the multiple vertical poles. The pressure plate is driven to move upward by pulling the handle upward. At this time, the refractory bricks to be sintered are placed on the placement rack, and the handle is released. Since one side of the multiple springs is on one side of the multiple circular plates, the elastic force generated by the multiple springs squeezes the pressure plate, further allowing the pressure plate to clamp the bricks to be sintered. At this time, the placement rack is pushed into the interior of the combustion chamber and the sealing cover is closed. The bricks are sintered inside the furnace body, so that the bricks are fixed when the refractory bricks are sintered to prevent the bricks from falling when they are placed in or taken out of the furnace body. At the same time, it can also ensure that the bricks maintain a stable position during the entire sintering process.

[0022] 2. In the present application, while sintering refractory bricks, the switch of the air pump is turned on, and suction is generated at the air inlet end of the air pump, so that the flue gas generated by the sintering inside the furnace body passes through the first pipe to the inside of the second pipe, and is further discharged into the inside of the stirring plate. While being discharged into the inside of the stirring plate, the flue gas passes through the turbine blades, which further causes the turbine blades to rotate, and further causes the rotating rod to drive the multiple stirring plates to rotate. The adsorptive material activated carbon is poured into the inside of the stirring plate through the sliding cover, and the leakage plate prevents the material from falling into the inside of the second pipe, and the screening holes on the leakage plate allow the flue gas to be discharged. The rotation of the multiple stirring plates stirs the activated carbon inside the treatment pipe, so that it is in full contact with the flue gas, which can effectively adsorb these harmful substances. The treated flue gas is then discharged through multiple air outlets, so that when the bricks are sintered, the flue gas generated is treated before being discharged, thereby reducing pollution to the environment and also reducing the concentration of harmful gases in the working environment.

The elastic force generated by the multiple springs 206 squeezes the pressing plate 205, further allowing the pressing plate 205 to clamp the bricks to be sintered, thereby limiting the position of the bricks;

[0038] The handle 208 is fixedly disposed on one side of the pressing plate 205 , and the pressing plate 205 is moved upward by pulling the handle 208 upward.

[0039] like Figure 1-6 As shown, a sealing cover 210 is provided on one side of the furnace body 1, and a pull plate 209 is fixedly provided on one side of the placement rack 202 close to the sealing cover 210, and multiple springs 206 are movably sleeved on the outer surfaces of multiple vertical rods 204, and the pull plate 209 facilitates pulling the placement rack 202.

[0040] like Figure 1-6 As shown, a first pipe 3 is installed on one side of the furnace body 1, and an air pump 301 is installed at one end of the first pipe 3. When the switch of the air pump 301 is turned on, suction is generated at the air inlet end of the air pump 301, so that the smoke generated by sintering inside the furnace body 1 comes into the inside of the second pipe 302.

[0041] like Figure 1-6 As shown, a second pipe 302 is provided at the outlet end of the air pump 301 , and a processing pipe 303 is provided on one side of the second pipe 302 through a flange, which passes through the first pipe 3 to the inside of the second pipe 302 and is further discharged into the stirring plate 305 .

[0042] like Figure 1-6 As shown, a rotating rod 304 is provided on one side of the inner wall of the processing pipe 303 through a bearing, and a turbine blade 306 is fixedly provided on the side of the rotating rod 304 close to the second pipe 302. When discharged into the interior of the stirring plate 305, it will pass through the turbine blade 306, further causing the turbine blade 306 to rotate.

[0043] like Figure 1-6 As shown, a plurality of stirring plates 305 are fixedly provided on the outer surface of the rotating rod 304, and a leakage plate 307 is provided on the outer surface of the rotating rod 304 through a bearing. The plurality of stirring plates 305 rotate to stir the activated carbon inside the treatment pipe 303 so that it is in full contact with the flue gas, and the leakage plate 307 can rotate because of the bearing.

[0044] like Figure 1-6As shown, a sliding cover 308 is provided on the outer surface of the processing pipe 303, and a plurality of air outlet holes 309 are opened on one side of the processing pipe 303. The adsorptive material activated carbon is poured into the inside of the stirring plate 305 by sliding the sliding cover 308, and the treated flue gas is discharged through the plurality of air outlet holes 309.

[0045] like Figure 1-6 As shown, slide grooves are provided on both sides of the inner wall of the combustion chamber 2 , and two sliders 201 can slide in the slide grooves on both sides of the combustion chamber 2 respectively.

[0046] Working principle: When the furnace body 1 is sintering the refractory bricks, the sealing cover 210 is opened, and the two sliders 201 can slide in the slide grooves on both sides of the combustion chamber 2 respectively, and the placing rack 202 is pulled by the pull plate 209, and the pressing plate 205 can slide on the outer surface of the plurality of vertical rods 204, and the pressing plate 205 is driven to move upward by pulling the handle 208 upward. At this time, the refractory bricks to be sintered are placed on the placing rack 202, and the handle 208 is released. Since one side of the plurality of springs 206 is located on the plurality of circular plates 20 On one side of 7, the elastic force generated by multiple springs 206 squeezes the pressing plate 205, further allowing the pressing plate 205 to clamp the bricks to be sintered. At this time, the placement rack 202 is pushed into the combustion chamber 2 to close the sealing cover 210, and the bricks are sintered inside the furnace body 1. Therefore, when the refractory bricks are sintered, the bricks are fixed to prevent the bricks from falling when they are placed in or taken out of the furnace body 1. At the same time, it can also ensure that the bricks maintain a stable position during the entire sintering process. At the same time, the switch of the air pump 301 is turned on, and the air inlet end of the air pump 301 generates suction, so that the flue gas generated by sintering inside the furnace body 1 passes through the first pipe 3 to the inside of the second pipe 302, and is further discharged into the inside of the stirring plate 305. While being discharged into the inside of the stirring plate 305, it passes through the turbine blade 306, which further causes the turbine blade 306 to rotate, and further causes the rotating rod 304 to drive the multiple stirring plates 305 to rotate, and the adsorbent material activated carbon is poured into the inside of the stirring plate 305 through the sliding cover 308. The leak plate 307 prevents the material from falling into the inside of the second pipe 302, and the screening holes on the leak plate 307 allow the flue gas to be discharged. The multiple stirring plates 305 rotate to stir the activated carbon inside the treatment pipe 303, so that it is fully in contact with the flue gas, which can effectively adsorb these harmful substances. The treated flue gas is then discharged through the multiple air outlets 309, so that when the bricks are sintered, the generated flue gas is treated before being discharged, thereby reducing pollution to the environment and also reducing the concentration of harmful gases in the working environment.

[0047] The above are only preferred embodiments of the application, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
