Detailed Description

The present invention will be further described with reference to the following drawings and detailed description, wherein the descriptions of "left", "right", etc. refer to fig. 1 for reference:

as shown in fig. 1-13, a baking system of an assembled sintered wallboard comprises a tunnel baking room 1, a heat energy comprehensive utilization device 4, and a brick plate transportation flat car 5, wherein both ends of an inlet and an outlet of the tunnel baking room 1 are respectively connected with a vehicle-in transition chamber 2 and a vehicle-out transition chamber 3, the vehicle-in transition chamber 2 and the vehicle-out transition chamber 3 play a role of vehicle-in and vehicle-out transition, and can also effectively prevent the heat of the tunnel baking room 1 from escaping, reduce energy consumption and protect the environment, the heat energy comprehensive utilization device 4 is installed on the tunnel baking room 1, a large amount of heat can be generated during baking operation of wallboard components (building blocks, whole plates and the like), the wallboard components need to be rapidly cooled and shaped after being baked, the heat can be greatly wasted during the cooling process of a traditional baking kiln, therefore, the heat energy comprehensive utilization device 4 is designed to recycle the heat energy, and when the wallboard components are molded by extrusion, the water content in the wall board part is too high, and the wall board part can crack and scrap when directly entering the tunnel roasting room 1 for operation, so a primary high-temperature drying chamber can be designed to carry out early drying on the wall board part, so that the water content of the wall board part when entering the tunnel roasting room 1 is less than 3 percent, the primary high-temperature drying chamber needs a large amount of high-temperature air for drying, and the energy consumption is larger, the invention conducts the hot air at the cooling section of the tunnel roasting room 1 to the primary high-temperature drying chamber for recycling through the heat energy comprehensive utilization device 4, can greatly reduce the energy consumption requirement of the primary high-temperature drying chamber, the wall board part just entering the tunnel roasting room 1 can not be directly roasted, and needs to be gradually heated to remove the residual water content so as to avoid the cracking phenomenon of the wall board part, and the heating process also needs a large amount of heat, the invention realizes the heat energy circulation in the tunnel type roasting room 1 through the heat energy comprehensive utilization device 4, meets the heat demand of the preheating section before roasting, thus effectively reducing the installation amount of heat supply equipment and energy consumption, effectively saving energy and reducing emission through the heat energy comprehensive utilization device 4, reducing the production cost of enterprises, orderly passing building materials carried by a tile plate transport flat car 5 from the tunnel type roasting room 1 for roasting operation, piling up wall plate components on the tile plate transport flat car 5, leading the tile plate transport flat car 5 to move forward by one car tightly pushing another car in the tunnel type roasting room 1, the tunnel type roasting room 1 comprises a roasting room body 11, temperature-insulating refractory wall plates 12 are connected on the two inner side walls of the roasting room body 11, effectively preventing heat from escaping outwards to cause energy consumption, a top plate lifting mechanism 13 is arranged at the top of the inner side of the roasting room body 11, and the traditional roasting kiln is highly fixed, because the traditional bricks are basically consistent in size and dimension, the stacking height of the bricks is fixed, the stacking height of the bricks is 1.8 meters generally, the top plate is designed to be 1.9 meters, so that the flames can not escape and air convection space can be ensured, the wall plate parts needing to be roasted in the invention are made of new materials, have different appearance dimensions, and are also provided with holes, particularly thin-wall plate parts, the stacking height of the wall plate parts cannot be too high (the stacking height is too high, and collapse accidents can occur during stacking), when the stacks of the thin-wall plate parts enter the roasting kiln with the fixed top, the gap between the top plate and the stacks is large, the fire channeling phenomenon can occur, and the roasting operation quality is influenced, therefore, the invention designs the top plate lifting mechanism 13, realizes the change of the height space in the roasting room body 11 by lifting the top plate, and can meet the roasting requirements of different products, the baking room body 11 is sequentially provided with a preheating area 111, a high-temperature baking area 112 and a cooling and cooling area 113 along the advancing direction of the brick plate transporting flat car 5, which is determined according to the baking process, the wallboard part firstly removes residual moisture in the preheating area 111, then carries out baking operation in the high-temperature baking area 112, and finally goes to the cooling and cooling area 113 for cooling and shaping and output.

The lifting top plate mechanism 13 comprises a heat insulation top plate 131 and a top plate lifting device 133, the heat insulation top plate 131 is formed by splicing steel frames, fire-resistant and heat-insulating materials are filled in the heat insulation top plate 131, the heat insulation top plate has a heat insulation effect, a top plate lifting guide rod 132 is vertically connected to the upper end surface of the heat insulation top plate 131, the top plate lifting guide rod 132 plays a lifting guide role of the heat insulation top plate 131, so that the heat insulation top plate 131 can be lifted stably, the top plate lifting device 133 is installed at the top of the roasting room body 11, the top plate lifting device 133 is in transmission connection with the heat insulation top plate 131, the top plate lifting device 133 is lifting power equipment of the heat insulation top plate 131, and can select equipment such as a hoist crane, an ascending limiting seat 134 and a descending limiting seat 135 are installed and fixed on the inner wall of the heat insulation fire-resistant wall plate 12, the ascending limiting seat 134 and the descending limiting seat 135 are filled with the heat-resistant materials, two side ends of the heat insulation top plate 131 are connected with isolation inserting plates 1311, the ascending limiting seat 134 and the descending limiting seat 135 are arranged on the motion track line of the isolation inserting plate 1311, and the isolation inserting plate 1311 can be inserted into the ascending limiting seat 134 or the descending limiting seat 135, so that the edge of the heat insulation top plate 131 can be sealed and isolated, heat and air can be effectively prevented from escaping from the edge of the heat insulation top plate 131, and a closed operation environment can still be kept after the size of the indoor space of the roasting room body 11 is adjusted.

The lifting scale 1321 is arranged on the top plate lifting guide rod 132, and whether the heat insulation top plate 131 descends in place can be intuitively calculated according to the descending condition of the lifting scale 1321, so that the heat insulation top plate 131 does not need to be observed in the roasting room body 11, and the operation of equipment operators is facilitated.
