[0036] The feed inlet 101 of the furnace body 100 is provided with a blower 103, and the air outlet of the blower 103 is connected to an air delivery pipe 104, and the end of the air delivery pipe 104 away from the blower 103 is placed in the furnace body 100, so as to realize the air input of the end of the furnace body 100 close to the feed inlet 101. The blower 103 is connected to the control center, and the control center controls the opening and closing of the blower 103, and the adjustment of the blowing volume after opening. The blower 103 delivers air to the furnace body 100 under the action of the air delivery pipe 104, and its delivery range is from the feed inlet 101 of the furnace body 100 to the half of the furnace body 100 close to the feed inlet 101.

[0037] A gas delivery network is disposed on the outer wall of the furnace body 100 , and the diameter of the rotating gear is larger than the diameter of the column formed by the gas delivery network, that is, the rotating gear protrudes from the gas delivery network in the direction away from the furnace body 100 .

[0038] A cooling device is provided at one end of the furnace body 100 near the discharge port 102, and the cooling device is used to reduce the temperature of the material at one end of the discharge port 102, and includes a coil 105 and a cooling trough 106. The coil 105 is wound around the furnace body 100 at one end of the discharge port 102, and a coolant is provided in the cooling trough 106. The cooling trough 106 is provided vertically below the furnace body 100 at one end of the discharge port 102, that is, below the furnace body 100 where the coil 105 is provided, and one end of the coil 105 near the placement plane is placed in the coolant in the cooling trough 106.

[0039] The gas delivery network includes a steam delivery network and an air delivery network. The steam delivery network is connected to the steam delivery pipeline through a rotary joint, and the air delivery network is connected to the air delivery pipeline through a rotary joint. When the furnace body 100 rotates under the drive of the rotary drive device, the gas delivery network also rotates accordingly, and under the action of the rotary joint, the connection with the steam delivery pipeline and / or the air delivery pipeline is ensured. The end of the steam delivery network away from the steam delivery pipeline is divided into a plurality of output ports, each of which is respectively connected to a steam nozzle 108, and the end of the air delivery network away from the air delivery pipeline is respectively connected to an air nozzle.

[0040] The inner wall of the furnace body 100 is provided with a plurality of steam nozzles 108 and a plurality of air nozzles. Specifically, the steam nozzles 108 are evenly dispersed on the entire inner wall of the furnace body 100, and the air nozzles are evenly dispersed on the inner wall of the furnace body 100 near the discharge port 102. The air nozzles are arranged on the inner wall of the furnace body 100 away from the feed port 101. The plurality of air nozzles and the air delivery pipe network constitute a wall-mounted fan.

[0041] The steam delivery network is divided into N steam delivery areas in the delivery direction of the furnace body 100, where N is an integer greater than or equal to 2. A first control valve is respectively provided on the steam delivery network corresponding to each steam delivery area. The steam nozzle 108 at the location of each steam delivery area is connected to the delivery network of the steam delivery area, and the control center controls the steam delivery amount of different steam delivery areas by controlling the first control valve of the steam delivery network corresponding to the steam delivery area. The length of each steam delivery area in the delivery direction of the furnace body 100 can be the same, or it can gradually decrease / increase along the delivery direction of the furnace body 100.

[0042] Each steam delivery zone is provided with n steam delivery blocks 107 in a direction perpendicular to the extension direction of the furnace body 100, that is, in the longitudinal direction of each steam delivery zone, the current steam delivery zone is evenly divided into n steam delivery blocks 107 according to arcs. The steam delivery pipe network corresponding to each steam delivery block 107 is respectively provided with a third control valve. n is an integer greater than or equal to 3, and here n is taken as an example of 5, at which time the corresponding central angle of each steam delivery block 107 is 72 degrees, and the specific division is as follows: Figure 2 shown.

[0043] The furnace body 100 is divided into a first air conveying range and a second air conveying range in the material conveying direction. The first air conveying range is located at one end of the furnace body 100 close to the feed port 101. The length of the first air conveying range in the conveying direction of the furnace body 100 is equal to the conveying distance of the blower 103, that is, when the blower 103 is under the action of the air delivery duct 104, the air conveying range of the first air conveying range is the first air conveying range. The length of the first air conveying range in the conveying direction of the furnace body 100 is optimally half the length of the furnace body 100. The end of the first air conveying range away from the feed port 101 is the second air conveying range, and the air nozzle is arranged on the inner wall of the second air conveying range of the furnace body 100. The second air conveying range is half of the length of the furnace body 100 in the conveying direction away from the feed port 101.

[0044] The air delivery duct is arranged on the outer wall of the furnace body 100 in the second air delivery range, and the air nozzle is arranged on the inner wall of the furnace body 100 in the second air delivery range. It should be noted that the setting position of the air nozzle needs to meet the air demand of the furnace body 100 at one-half away from the feed inlet 101 during activation. The air delivery duct corresponds to the air nozzle relative to the furnace body 100 to ensure the supply of air to the nozzle during air input. Optimally, the air delivery duct and the air nozzle can be arranged at three-quarters of the furnace body 100 away from the feed inlet 101, that is, the furnace body 100 is divided into four parts along the direction from the feed inlet 101 to the discharge port 102, the air delivery duct is arranged at the outer wall of the third part of the furnace body 100, and the air nozzle is arranged at the inner wall of the third part of the furnace body 100.

[0045] The air delivery pipeline is divided into M air delivery areas in the delivery direction of the furnace body 100, wherein M is an integer greater than or equal to 2. A second control valve is respectively provided on the air delivery pipe network corresponding to each air delivery area.

[0046] Since the steam needs to be in full contact with the material, the steam nozzle 108 for spraying steam is placed in the material when the steam is input, that is, the steam nozzle 108 for spraying steam is located on the side of the furnace body 100 close to the ground. When the air is input, it needs to be in full contact with the material. When the material is lifted by the lifting plate, the air nozzle placed above the material should spray air, that is, the air nozzle that sprays air is located on the side of the furnace body 100 away from the ground. Therefore, within the second air delivery range, the steam nozzle 108 and the air nozzle can be shared or separately set. Of course, within the second air delivery range, the steam delivery pipe network connected to the steam nozzle 108 and the air delivery pipe network connected to the air nozzle can also be a parallel structure or can be set separately.

[0047] In the first air delivery range, the control center controls the air input amount by controlling the power of the blower 103. In the second air delivery range, the control center controls the air delivery amount of different air delivery areas by controlling the second control valve of the air delivery pipe network corresponding to different air delivery areas.

[0048] Each air delivery zone is provided with m air delivery blocks in a direction perpendicular to the extension direction of the furnace body 100, that is, in the longitudinal direction of each air delivery zone, the current air delivery zone is evenly divided into m air delivery blocks according to the arc. The air delivery pipe network corresponding to each air delivery block is respectively provided with a fourth control valve. The m is an integer greater than or equal to 3, and here m is taken as an example of 5, at this time, the corresponding central angle of each air delivery block is 72 degrees. The air delivery block is similar to the arrangement of the steam delivery block 107, and the structure of the air delivery block can refer to Figure 2 .

[0049] The control center is connected to the first control valve, the second control valve, the third control valve and the fourth control valve respectively, and controls the gas delivery amounts of different steam delivery areas and / or different air delivery areas, different steam delivery blocks 107 and / or different air delivery blocks by controlling the first control valve, the second control valve, the third control valve and the fourth control valve.

[0050] The feed port 101 and the discharge port 102 of the furnace body 100 are respectively provided with gas monitoring devices, including gas flow rate monitoring, gas oxygen content detection and gas water content detection. The gas monitoring devices are connected to the control center and the monitored raw gas data are sent to the control center in real time. Multiple gas monitoring devices can be provided, and there is no requirement for their number here. It should be noted that multiple gas monitoring devices can be evenly provided without affecting the feeding and discharging, so as to ensure the accuracy of the monitored gas data.

[0051] The control center pre-processes the received raw gas data to obtain gas data. The control center pre-processes the raw gas data by calculating the average value of the gas monitoring device of the feed port 101 and the gas monitoring device of the discharge port 102, respectively, so as to obtain the gas data of the feed port 101 and the gas data of the discharge port 102 in real time.

[0052] The furnace body 100 is provided with a reference point, and the non-rotating part of the furnace body 100 is provided with a starting point. The control center calculates the state of the material in the furnace body 100 according to the angle between the reference point and the starting position of the furnace body 100, thereby determining the input of water vapor and / or air to the furnace body 100. The reference point and the starting point are preset positions. The angle relationship between the reference point and the starting position of the furnace body 100 can be determined by the rotation angle of the rotary drive device, and no specific limitation is made here. The control center is provided with a positional relationship between the reference point and different steam delivery blocks 107 and / or different air delivery blocks, which can be each steam delivery block 107 and / or each air delivery block.

[0053] The control center includes an input unit, a construction unit, an analysis unit, a storage unit and a display unit. The input unit is used to input activation information and node information, the construction unit constructs a relationship map based on the activation information and node information to obtain an activation map of a demand relationship, the analysis unit selects the position and amount of water vapor and / or air at the next moment based on the amount of water vapor and / or air introduced at the previous moment and gas data, the storage unit is used to store each node information, and the display unit displays the activation map.

[0054] The activation information is the key information provided by the construction unit when constructing the activation map, including key data in the production process such as activation time, activation temperature, water vapor usage, air usage, water vapor input, air input, raw material quantity, product quantity or product grade. The activation information is a key node for creating a demand relationship map, and the activation information input by the input unit includes at least one.

[0055] The node information includes key entities represented by key nodes, other entities related to the key entities, and relationship edges between the key entities and other entities. Specifically, the node information refers to the relationship between two different entities, and each node information is a single relationship graph. Each node information includes at least i related nodes, and the relationship between them, i is a positive integer greater than or equal to 2. Among them, the related nodes include a key node and j other nodes, j=i-1. The key node represents the key entity in the node information, and the other nodes represent other entities in the node information except the key entity. Each other entity is connected to the key entity through a relationship edge, and each relationship edge is an association relationship between other entities and the key entity.

[0056] For example, the key entity is the feed volume of 500 kg per hour, the related edge is the feed of 2 hours, and the other entity is the feed of 1000 kg; the key entity is the furnace body 100 speed 1rp / min, the related edge is the material entering the furnace body 100 for 10 minutes, and the other entity is the material distance from the feed port 0.5m.

[0057] The node information includes a relationship map between different entities and different data in each stage of feeding, activation and discharging to meet common production needs.

[0058] The input unit can input single node information or modify single node information. All node information of the storage unit constitutes a node database, in which each node information is stored in the order of the production process. The node database sets process partitions according to the production process corresponding to the node information, for example: pre-activation partition, activation partition and completed activation partition, and stores the node information in the corresponding process partition according to the production process, so as to facilitate the construction unit to quickly select the corresponding node information when constructing the relationship map, thereby improving the construction speed of the activation map.

[0059] When the construction unit constructs the relationship graph, Figure 3 As shown, the specific steps include:

[0060] Step 1: According to the production process stage of the current activation information, the key entity corresponding to the current activation information is searched in the corresponding process partition in the node database to obtain the node information of the key entity corresponding to the current activation information;

[0061] Step 2: the construction unit searches at both ends of the node database according to the location of the node information of the key entity corresponding to the current activation information. At this time, the key entity to be searched is the other entity in the node information searched last time;

[0062] Step 3, the construction unit arranges the searched related node information according to the order in the node database to obtain a related node information set of the activation map;

[0063] Step 4: the construction unit associates and combines the node information in the associated node information set to obtain an activation map.

[0064] The control center is also connected to the feeding device of the feeding port and the discharging device of the discharging port of the furnace body.

[0065] The construction unit sets the activation parameters of the furnace body 100 according to the obtained activation spectrum, and displays the activation spectrum on the display unit. The administrator modifies / confirms the activation spectrum displayed on the display unit. When the administrator modifies the activation spectrum, the activation parameters of the furnace body 100 are modified synchronously. When the administrator confirms the activation spectrum, the furnace body 100 starts the activation operation, including feeding, activation, discharging, etc., to achieve precise production.

[0066] In the node information, a virtual beam emitting device is respectively set between the key entity and each other entity, and each other entity is set with a virtual beam receiving device corresponding to the virtual beam emitting device, and each virtual beam receiving device is respectively associated with the corresponding virtual beam emitting device, that is, the virtual beam receiving device only receives the virtual beam emitted by the corresponding virtual beam emitting device. The virtual beam emitted by the virtual beam emitting device includes the association relationship between other entities and the key entity, forming a relationship edge between the key entity and other entities.

[0067] The construction unit includes a deflection device, which is used to adjust the deflection angle of the relationship edge in the node information, deflect the relationship edge and other entities connected to the relationship edge, so that the activation map forms a three-dimensional map.

[0068] When the construction unit constructs the relationship graph, step 4 specifically includes:

[0069] Step 41, the construction unit randomly selects a node information in the associated node information set, takes the key entity in the node information as the starting node, and selects the node information containing the key entity in the associated node information set, and connects them in sequence according to the connection relationship of the relationship edge to obtain a two-dimensional activation map;

[0070] In step 42, the construction unit takes the starting node as the center and uses the deflection device to perform angle deflection on each relationship edge to obtain the activation spectrum. At this time, the activation spectrum is a three-dimensional spectrum.

[0071] In step 42, the deflection device performs angle deflection on each relationship edge, specifically including: the construction unit reads the number of relationship edges connecting the entity to be deflected, calculates the deflection angle of the relationship edge connecting the node, and the deflection device performs angle deflection on each relationship edge connecting the node according to the deflection angle. When selecting an entity, the construction unit takes the starting node as the starting point and deflects the relationship edge of each entity in turn along the connection relationship of the relationship edge. The construction unit calculates the deflection angle of the relationship edge connecting the node by: obtaining the number of relationship edges of the entity to be deflected, calculating the projection angle of each two adjacent relationship edges of the entity to be deflected on the horizontal plane, for example, if the number of relationship edges of the entity to be deflected is 6, then the projection of the angle of each two adjacent relationship edges of the entity to be deflected on the horizontal plane is 60 degrees. The projection angle refers to the angle between the projection lines of two relationship edges on the horizontal plane.

[0072] The deflection device includes a virtual reflector and an adjustment structure, and the adjustment structure adjusts the reflection angle of the virtual reflector according to the deflection angle. The virtual reflector deflects the virtual light beam of the relationship edge and adjusts the connection angle of the relationship edge. The construction unit adjusts the position of the virtual light beam receiving device corresponding to the virtual light beam emitting device in the key entity according to the deflection angle, that is, the construction unit adjusts the position of other entities corresponding to the virtual light beam emitting device in the key entity according to the deflection angle. The adjustment can be that the construction unit takes the current key entity as the origin, calculates the position coordinates of other entities corresponding to the virtual light beam emitting device in the key entity according to the deflection angle and the distance between the current key entity and the current other entities, and obtains the adjustment coordinates. The construction unit adjusts the position of the corresponding other entity to the position represented by the adjustment coordinates according to the adjustment coordinates of the corresponding other entity, thereby realizing the angular deflection of the relationship edge and other entities.

[0073] The steam delivery zone has the same boundary range as the first air delivery range and the second air delivery range.

[0074] The gas monitoring device provided at the feed port 101 is a first gas monitoring device, and the raw gas data of the first gas monitoring device is processed by the control center to obtain the first gas data. The gas monitoring device provided at the discharge port 102 is a second gas monitoring device, and the raw gas data of the second gas monitoring device is processed by the control center to obtain the second gas data. The first gas data includes the oxygen percentage value of the feed port 101 and the water vapor percentage value of the feed port 101, and the second gas data includes the oxygen percentage value of the discharge port 102 and the water vapor percentage value of the discharge port 102.

[0083] Table 4: Comparison table of water content of the second gas data

[0084] After the analysis unit calculates the adjustment amount of air and / or water vapor according to the gas adjustment comparison table, the control center sends an adjustment command to the furnace. The control center controls the first control valve and the second control valve to adjust the amount of water vapor and / or air, thereby ensuring the supply of oxygen and / or water vapor during the activation process and improving the quality of the finished product.

[0085] The high-efficiency rotary kiln with a wall-mounted fan adopts a combination of a wall-mounted extension and a blower, which reduces the air or oxygen recoil caused by the pressure in the furnace, while ensuring the uniform distribution of oxygen in the rotary kiln, thereby improving the quality of the required products. In addition, the rotary kiln in the present invention constructs a relationship map to obtain an activation map of the demand relationship, and the control center adjusts the activation parameters of the rotary kiln according to the activation map to achieve precise production. In addition, the activation map is constructed as a three-dimensional map in the present invention, and the administrator can quickly adjust the activation parameters through the display device to avoid the two-dimensional map being too large and affecting the overall map appearance. Finally, the present invention sets a gas monitoring device at the feed port and the discharge port respectively to detect the content of oxygen and water vapor in the output gas, so as to timely adjust the amount of oxygen / air and water vapor introduced into the furnace body, further ensuring the quality of the activated product.
