Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] refer to Figure 1 , Figure 2 and Figure 3 This utility model provides a quicklime conveying and storage device for sintering, including a quicklime silo 1, a quicklime tank car 2, and a conveying pipe 3 connecting the quicklime silo 1 and the quicklime tank car 2. A dust removal component 4 is provided on the top of the quicklime silo 1. The dust removal component 4 is a dust collector with a filter bag inside. The dust removal component 4 can reduce the pressure inside the quicklime silo 1 and play a role in dust removal during the conveying operation.

[0020] refer to Figure 1 , Figure 2 and Figure 3 It also includes a lime feeding assembly 5, an explosion-proof assembly 6, and a control assembly 7. The lime feeding assembly 5 includes a gas storage tank 51 and an air blowing pipe 52 connected to the gas outlet of the gas storage tank 51. The gas storage tank 51 stores nitrogen gas, and the air outlet of the air blowing pipe 52 is connected to the lime conveying pipe 3. A quick-cut control valve 53 is installed on the air blowing pipe 52. When the quicklime tanker 2 conveys quicklime into the quicklime silo 1, nitrogen gas is blown into the lime conveying pipe 3 to deliver the quicklime into the quicklime silo 1. The signal receiving end of the quick-cut control valve 53 is connected to the signal output end of the control assembly 7.

[0021] refer to Figures 1-4 The explosion-proof component 6 is used to monitor the ash storage status in the quicklime silo 1 in real time and to cut off the quick-cut control valve 53 in time to stop feeding material into the quicklime silo 1. The explosion-proof component 6 includes a pressure detector 61 installed on the top of the quicklime silo 1. The signal output terminal of the pressure detector 61 is connected to the signal receiving terminal of the control component 7. The explosion-proof component 6 also includes a fixing frame 62 sleeved on the quicklime silo 1 and a weighing detector 63 installed below the fixing frame 62 to support the quicklime silo 1. At least two weighing detectors 63 are provided and are evenly distributed along the circumference of the quicklime silo 1. In this example, four weighing detectors are provided. The signal output terminals of the weighing detectors 63 are all connected to the signal receiving terminal of the control component 7.

[0022] refer to Figures 1-4During the process of transferring quicklime from the quicklime tanker 2 to the quicklime silo 1, the pressure detector 61 detects the pressure inside the quicklime silo 1, and the weighing detector 63 detects the weight of the quicklime silo 1. When the pressure inside the silo is detected to be outside the set value, a signal is transmitted to the control component 7. The control component 7 then controls the quick-cut control valve 53 to close, thereby stopping the transfer of quicklime into the quicklime silo 1 and preventing the silo 1 from bursting due to excessive pressure. An alarm can be installed on the control component 7. When the quick-cut control valve 53 is closed, the alarm will sound, promptly reminding on-site personnel to check and repair the silo. When the weighing detector 63 detects that the total weight of the quicklime silo 1 containing quicklime is outside the set range, a signal is also transmitted to the control component 7 to control the quick-cut control valve 53 to close, preventing the silo from bursting due to excessive quicklime transfer.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The top of the quicklime silo 1 is also equipped with a pressure relief component 8, which is the silo explosion relief valve. The function of the explosion relief valve is to quickly open when a dust explosion occurs inside the silo, and guide the high temperature and high pressure flame and shock wave generated by the explosion in a safe direction, thereby protecting the main structure of the silo from being destroyed and preventing catastrophic accidents.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The front end of the air blowing pipe 52 is equipped with a manual control valve 9, and the rear end of the air blowing pipe 52 is equipped with a flow controller 10. The manual control valve 9 enables manual opening of the ash conveying, and the flow controller 10 can adjust the ash conveying flow rate according to the actual situation to control the feeding speed in the quicklime silo 1.

[0025] refer to Figure 1 , Figure 2 and Figure 3 The control component 7 includes a display screen 11, which displays the pressure and weight inside the quicklime silo 1. The display screen 11 allows on-site personnel to conveniently monitor the ash conveying status inside the silo in real time.

[0026] In summary, by interlocking the pressure detector 61, the weighing detector 63, and the quick-cut control valve 53, the feeding situation in the quicklime silo 1 can be monitored in real time. When the feeding situation is outside the set range, the quick-cut control valve 53 can be shut off in time to stop the feeding of quicklime into the quicklime silo 1, thereby avoiding the risk of silo cracking and explosion and improving safety performance.

[0027] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model.
