Referring to fig. 1 to 3, an ash conveying device 10 includes an ash pipe 100 and an ash monitoring mechanism 200.
The ash pipe 100 has a nozzle for guiding ash in the ash storage 300 to the ash truck 400 through the ash pipe 100.
The ash monitoring mechanism 200 comprises a first rotating shaft 210, a rotating wheel 220 and a sensor 230, wherein the rotating wheel 220 is connected to the first rotating shaft 210, the rotating wheel 220 is provided with a plurality of first rotary vanes 221 which are arranged along the circumferential direction, part or all of the first rotary vanes 221 are positioned on an ash discharging path of the ash discharging pipe 100, ash can strike the first rotary vanes 221 in discharging to enable the rotating wheel 220 to rotate, and the sensor 230 is installed at the side part of the rotating wheel 220 and is used for monitoring whether the rotating wheel 220 rotates or not.
If the rotating wheel 220 is in a movable state, that is, if the first rotating piece 221 of the rotating wheel 220 is not blocked or is subjected to resistance, the ash falls down from the ash discharging pipe 100 under the action of gravity, and impacts on the first rotating piece 221 to rotate the rotating wheel 220, the sensor 230 installed at the side of the rotating wheel 220 can monitor whether the rotating wheel 220 rotates, so as to determine whether the rotating wheel 220 is in a movable state or whether the ash falls down normally.
In the embodiment shown in fig. 1, the ash monitoring mechanism 200 further includes a fixing frame 240, the fixing frame 240 is connected to the lower end of the ash discharging pipe 100, and both ends of the first rotating shaft 210 are fixed to the fixing frame 240. In other embodiments of the present application, the first rotating shaft 210 may also be fixed to the lower side of the ash pipe 100 through other external structures.
Optionally, the sensor 230 is attached to an inner wall of the holder 240.
The present application is not limited to the manner of fixing the first rotating shaft 210, and the first rotating shaft 210 may be fixed to the lower side of the dust discharge pipe 100.
In the embodiment shown in FIGS. 2-3, the number of the first vanes 221 of the wheel 220 is 6. In other implementations of the present application, the number of the first rotary vanes 221 of the rotary wheel 220 may also be 3, 4, 5, 7 or more.
The first swing piece 221 is formed in an arc structure along a rotation direction thereof.
The arc-shaped structure can reduce the resistance of the first rotary vane 221 during rotation, increase the contact area between the falling ash and the first rotary vane 221, and ensure that the rotating wheel 220 rotates normally when not subjected to resistance.
It should be noted that all the first rotating blades 221 of the rotating wheel 220 rotate in the same direction.
Optionally, the first rotor 221 has a first end near the center of rotation and a second end far from the center of rotation, and the first rotor 221 is thinned by extending from the first end to the second end, so that the second end of the first rotor 221 is formed into a blade-shaped structure.
Since the ash is easy to scatter and cause secondary environmental pollution, the ash needs to be humidified before being transferred from the ash storage 300 to the ash transport cart 400, and the humidified ash is easy to agglomerate and cake, and when the ash falls to the opening of the ash discharge pipe 100, the agglomerated and caked ash may be stuck on the first rotary piece 221 of the rotary wheel 220. The second end of the first rotary vane 221 is designed to form a blade-shaped structure, the blade-shaped structure can cut or crush agglomerated and caked ash, the breaking force of the rotating wheel 220 on the agglomerated and caked ash is increased, and then the phenomenon that the agglomerated and caked ash is clamped on the first rotary vane 221 of the rotating wheel 220 is avoided.
Further, the side of the first vane 221 is also formed as a knife-edge structure, further increasing the crushing force of the rotating wheel 220 to the agglomerated and caked ash.
It should be noted that the blade structure may be directly ground or cut at the second end of the first rotor 221, or a cutting blade may be installed at an end of each first rotor 221 away from the rotation center. That is, the present application does not limit the specific form of the blade structure, but only provides the blade shape.
Optionally, the edge of the blade structure is serrated.
Because the ash needs to be humidified before being transferred from the ash storage 300 to the ash transport vehicle 400, the ash is not discharged too fast, so as to avoid the situation of insufficient humidification. The ash material with a slower flow rate is not dispersed into the ash cart 400 in time, but rather is formed into a cone shape. The edges of the knife-edge structure are designed to be serrated to facilitate the runner 220 to dump and pulverize the ash accumulated in the ash cart 400.
Referring to fig. 1, when the first rotary vane 221 of the rotary wheel 220 is located on the ash discharging path of the ash discharging pipe 100, the rotary direction of the rotary wheel 220 may be changed according to the ash discharging amount at different positions, and may be clockwise rotation, or counterclockwise rotation, or clockwise and counterclockwise rotation alternately.
Referring to fig. 4, when the first rotating plate 221 of the rotating wheel 220 is partially located on the ash discharging path of the ash discharging pipe 100, that is, only one side of the rotating wheel 220 is located on the ash discharging path of the ash discharging pipe 100.
In the embodiment shown in fig. 4, the left side of the wheel 220 is hit by the falling ash, and the wheel 220 rotates counterclockwise. In other embodiments of the present application, if only the right side of the wheel 220 is impacted by the falling ash, or the right side of the wheel 220 is impacted more by the falling ash, the wheel 220 rotates clockwise.
Referring to fig. 1, the ash monitoring mechanism 200 further includes an ash scraping wheel 250 for pushing and crushing the ash accumulated on the lower side of the ash monitoring mechanism 200 during the rotation process.
When the first rotary vane 221 of the rotary wheel 220 is located on the ash discharging path of the ash discharging pipe 100, the ash scraping wheel 250 can be connected to the first rotating shaft 210 in a transmission manner, that is, the first rotating shaft 210 can rotate to drive the ash scraping wheel 250 to rotate. In addition, the dust scraping wheel 250 can also be connected to the second rotating shaft 260 in a transmission manner.
Optionally, the ash scraping wheel 250 is disposed in the middle of the lower side of the ash pipe 100.
Referring to fig. 4, when the first rotating blade 221 of the rotating wheel 220 is partially located on the ash discharging path of the ash discharging pipe 100, the ash scraping wheel 250 is drivingly connected to the second rotating shaft 260.
Wherein, the ash scraping wheel 250 and the rotating wheel 220 are arranged in a staggered way, and the first rotary vane 221 and the second rotary vane 251 are prevented from contacting and colliding in the rotating process.
It should be noted that, when the ash scraping wheel 250 and the rotating shaft are connected to the first rotating shaft 210 at the same time, the rotating wheel 220 is movably sleeved on the first rotating shaft 210.
In the embodiment shown in fig. 1, the rotating shaft is sleeved on the first rotating shaft 210 through a bearing, and the ash scraping wheel 250 is in interference fit with the first rotating shaft 210.
When the rotating shaft is connected to the first rotating shaft 210, the ash scraping wheel 250 is connected to the second rotating shaft 260, and the rotating shaft can be movably sleeved on the first rotating shaft 210; or directly and fixedly connected to the first rotating shaft 210, and the first rotating shaft 210 can be rotated by the rotating wheel 220.
The rotation radius of the ash scraping wheel 250 is larger than that of the rotating wheel 220, so that the ash scraping wheel 250 can better push and crush the ash accumulated on the lower side of the ash monitoring mechanism 200, and the accumulated ash is prevented from blocking the rotation of the rotating wheel 220.
The ash conveying device 10 further includes a motor 270, and when the ash scraping wheel 250 is connected to the first rotating shaft 210, the motor 270 is connected to an end of the first rotating shaft 210 for driving the first rotating shaft 210 to rotate; when the scraping wheel 250 is connected to the second rotating shaft 260, the motor 270 is connected to an end of the second rotating shaft 260 for driving the second rotating shaft 260 to rotate.
The scraping wheel 250 includes a plurality of second rotary blades 251.
In the embodiment shown in FIGS. 2-3, the number of the second rotary blades 251 of the scraping wheel 250 is 4. In other embodiments of the present disclosure, the number of the second rotary blades 251 of the scraping wheel 250 may be 3, 5, 6, 7 or more.
The second rotor 251 is formed in an arc structure in its rotational direction.
The arc-shaped structure can reduce the resistance of the second rotary blade 251 during rotation, increase the centrifugal force for scraping ash, and greatly improve the spreading effect of ash.
It should be noted that all the second rotary blades 251 of the scraping wheel 250 rotate in the same direction.
Optionally, the second rotor 251 has a first end near the center of rotation and a second end far from the center of rotation, and the second rotor 251 is thinned by extending from the first end to the second end, so that the second end of the second rotor 251 is formed into a blade-shaped structure.
Since the ash is easy to drift and cause secondary environmental pollution, the ash needs to be humidified before being transferred from the ash storage 300 to the ash transport cart 400, and the humidified ash is easy to agglomerate and cake, so that when the ash falls to the opening of the ash discharge pipe 100, the resistance of the ash scraping wheel 250 is increased. The second end of the second rotary blade 251 is designed to form a blade-shaped structure, and the blade-shaped structure can cut or crush agglomerated and caked ash materials and increase the crushing force of the ash scraping wheel 250 on the agglomerated and caked ash materials.
It should be noted that the blade structure may be directly ground or cut at the second end of the second rotor 251, or a cutting blade may be installed at an end of each second rotor 251 away from the rotation center. That is, the present application does not limit the specific form of the blade structure, but only provides the blade shape.
Optionally, the edge of the blade structure is serrated.
Because the ash needs to be humidified before being transferred from the ash storage 300 to the ash transport vehicle 400, the ash is not discharged too fast, so as to avoid the situation of insufficient humidification. The ash material with a slower flow rate is not dispersed into the ash cart 400 in time, but rather is formed into a cone shape. The design of the edge of the knife-edge structure as a saw-tooth shape facilitates the dust scraping wheel 250 to push and crush the accumulated dust in the dust cart 400, and prevents the accumulated dust from affecting the rotation of the rotating wheel 220.
Optionally, the second rotary plate 251 is provided with a plurality of through holes.
The mass of the second rotary piece 251 can be reduced, and the material consumption of the rotary piece is saved.
Referring to fig. 5, the present embodiment further provides a ash discharging system 20 including an ash storage 300, an ash transporting vehicle 400 and the ash conveying device 10.
The ash conveying device 10 is used for conveying the ash in the ash storage 300 to the ash conveying vehicle 400.
The ash conveying device 10 further comprises an ash discharger 500 and a humidifier 600, one end of the ash discharger 500 is mounted at the ash outlet of the ash storage bin 300, the other end of the ash discharger 500 is connected to one end of the humidifier 600, the other end of the humidifier 600 is connected to the inlet of the ash discharge pipe 100, and the ash truck 400 is located at the lower side of the rotating wheel 220.
The ash in the ash storage 300 passes through the ash discharger 500 and the ash discharge pipe 100 to reach the ash transport vehicle 400, when the ash transport vehicle 400 is not filled with the ash, the rotating shaft can rotate under the impact of the ash, and the sensor 230 mounted at the side of the rotating wheel 220 can monitor the rotation of the rotating wheel 220, and at the moment, the ash is kept discharged. When the ash truck 400 is full or has been loaded with a predetermined amount of ash, the lower end of the rotating wheel 220 sinks into the ash of the ash truck 400, i.e. the rotation of the rotating wheel 220 is blocked, after the ash impacts the first rotary vane 221, the rotating wheel 220 cannot rotate any more due to resistance, and the sensor 230 mounted at the side of the rotating wheel 220 can monitor that the rotating wheel 220 stops rotating, at this time, the unloading of the ash is stopped.
The ash storage bin ash unloading system 20 can accurately know whether the ash truck 400 is fully loaded or loaded with the ash material with the preset amount, can stop unloading in time, prevents the ash material from overflowing, and avoids causing secondary dust and polluting the ground.
The ash storage bin unloading system 20 comprises a controller, the controller is connected to the ash unloader 500 and the sensor 230, and when the controller receives a stop signal sent by the sensor 230, the controller controls the ash unloader 500 to stop unloading ash.
In summary, according to the ash conveying device and the ash discharging system of the ash storage bin of the embodiment of the present application, ash in the ash storage bin 300 reaches the ash transport vehicle 400 through the ash discharger 500 and the ash discharge pipe 100, when the ash transport vehicle 400 is not filled with ash, the rotating shaft can rotate under the impact of the ash, and the sensor 230 mounted on the side of the rotating wheel 220 can monitor the rotation of the rotating wheel 220, so as to keep the ash discharged. When the ash truck 400 is full or has been loaded with a predetermined amount of ash, the lower end of the rotating wheel 220 sinks into the ash of the ash truck 400, i.e. the rotation of the rotating wheel 220 is blocked, after the ash impacts the first rotary vane 221, the rotating wheel 220 cannot rotate any more due to resistance, and the sensor 230 mounted at the side of the rotating wheel 220 can monitor that the rotating wheel 220 stops rotating, at this time, the unloading of the ash is stopped. The ash storage bin ash unloading system 20 can accurately know whether the ash truck 400 is fully loaded or loaded with the ash material with the preset amount, can stop unloading in time, prevents the ash material from overflowing, and avoids causing secondary dust and polluting the ground.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
