The embodiment of the utility model provides and protects a powder tank, which comprises a tank body 10, a feeding pipe 20 and a control mechanism 30, wherein a containing cavity 110 is arranged in the powder tank, and a pressure safety valve 130 is arranged on the tank body 10. The feeding pipe 20 is communicated with the accommodating cavity 110, and the feeding pipe 20 is provided with a control valve 210, and the control valve 210 is used for controlling the on-off of the feeding pipe 20. The control mechanism 30 includes a controller 310 and a pressure sensor 320, wherein one end of the pressure sensor 320 is connected to the pressure relief valve 130, and the pressure sensor 320 is communicatively connected to the controller 310. The control valve 210 is in communication connection with the controller 310, and the controller 310 is configured to receive a pressure signal from the pressure sensor 320, and control the control valve 210 to close when a pressure value represented by the pressure signal is greater than or equal to a threshold value, where the threshold value is less than a discharge pressure of the pressure relief valve 130.
Specifically, the pressure sensor 320 and the controller 310, and the control valve 210 and the controller 310 may be connected by a wired connection or a wireless connection, which is not limited herein.
For the pressure relief valve 130, the pressure relief valve 130 is generally provided at the top of the can body 10. It should be noted that, the dust collector 120 is further disposed at the top of the tank 10, in the prior art, when a filter element of the dust collector 120 is blocked, and the feeding pipe 20 is in a continuous feeding state, a pressure value inside the tank 10 becomes large, and the pressure safety valve 130 is pushed to open to release pressure, but because the pressure value inside the tank 10 is not monitored in time, before a worker reaches the tank 10, the tank 10 may be grayed or roof-blown due to continuous feeding, and further, a certain potential safety hazard exists.
Further, the powder tank further comprises a standby dust collector 160, the standby dust collector 160 is in communication connection with the controller 310, and the controller 310 is used for controlling the standby dust collector 160 to be turned on when a pressure value represented by the pressure signal is greater than or equal to a threshold value. That is, when the filter element of the dust collector 120 becomes clogged, activating the backup dust collector 160 can further slow down the rate at which ash or roof fall occurs. A spare dust collector 160 is also provided on the top of the can 10 and spaced from the dust collector 120. The number of the spare dust collectors 160 is not limited to one, and two or three spare dust collectors may be provided, which is not limited herein.
In some embodiments of the present invention, the pressure safety valve 130 is connected to the pressure sensor 320, the pressure sensor 320 can detect a pressure signal at the pressure safety valve 130 in real time to obtain a pressure value inside the tank 10, and transmit the pressure signal to the controller 310, and the controller 310 receives the detected pressure signal and sends a closing signal to the control valve 210 to close the control valve 210 in a state that the pressure signal is greater than or equal to a threshold value, so as to block the feeding pipe 20 from feeding into the tank 10, thereby avoiding a situation that the tank 10 is grayed or topped when the filter element of the dust collector 120 is blocked.
To further enhance the detection of the can body 10, an alarm mechanism 40 is also provided. In some embodiments of the present invention, the alarm mechanism 40 is connected to the controller 310 via a first electrical connection 410, and the controller 310 is configured to control the alarm mechanism 40 to send an alarm signal when the pressure signal is greater than or equal to the threshold value.
That is, when the pressure signal detected by the pressure sensor 320 at the control valve 210 is greater than or equal to the threshold value, the controller 310 receives the pressure signal, and simultaneously controls the alarm mechanism 40 to send an alarm signal and sends a closing signal to the control valve 210, so as to realize blocking feeding into the tank 10 and simultaneously inform field workers of timely overhauling the dust collector 120, thereby timely overhauling the powder tank and avoiding potential safety hazards.
In some embodiments of the present invention, the warning mechanism 40 may be a warning light or a buzzer. For example, when the alarm mechanism 40 is an alarm lamp, the on-off state of the lamp is controlled to notify a field person, that is, when the pressure signal is greater than or equal to the threshold value, the alarm lamp can be controlled to be turned on, so that the field person can timely overhaul the dust collector 120. Similarly, when the alarm mechanism 40 is a buzzer, an alarm sound is given by the buzzer to inform field personnel of repairing the dust collector 120.
Specifically, a supporting frame 140 is arranged at the bottom of the tank 10, and the alarm mechanism 40 is connected with the supporting frame 140. The alarm mechanism 40 and the support frame 140 may be connected by a fixed connection, such as welding or bonding; the connection may also be detachable, such as a snap connection or a bolt and nut fit connection, which is not limited herein.
In some embodiments of the present invention, the pressure sensor 320 is a patch-type pressure sensor 320, the pressure sensor 320 is attached to the outer surface of the pressure relief valve 130, and specifically, the pressure sensor 320 is attached to the outer surface of the pressure relief valve 130. In some embodiments of the present invention, the pressure value may also be detected by an air pressure sensor, which is not limited herein.
For the control valve 210, in some embodiments of the present embodiments, the control valve 210 may be a pneumatic tube bladder valve. In other embodiments, the valve may be a pneumatic butterfly valve or a pneumatic pinch valve, which is not limited herein.
Specifically, in some embodiments of the present invention, the control valve 210 is connected to the controller 310 via a second electrical connection line 2110. That is, the controller 310 controls the on/off of the control valve 210 through the second electrical connection line 2110, that is, when the signal sent by the pressure sensor 320 is received by the controller 310 and is greater than or equal to the threshold value, the controller 310 sends a closing signal to the control valve 210 to avoid continuing to convey material into the tank 10, so as to prevent ash or roof from being blown out.
In some embodiments of the present invention, the pressure sensor 320 is connected to the controller 310 by a third electrical connection 3210. That is, the controller 310 obtains the signal transmitted by the pressure sensor 320 through the third electrical connection line 3210, that is, the pressure signal at the control valve 210 detected by the pressure sensor 320 can be obtained in time.
It should be noted that the pressure relief valve 130 has a discharge pressure value, and the threshold value is between eighty-five percent and ninety-five percent, preferably ninety percent, of the discharge pressure value. For example, the opening air pressure of the pressure safety valve 130 is 5000Pa, the set threshold value is 4500Pa, when the controller 310 detects that the air pressure in the powder tank reaches the threshold value, a signal is sent to enable the alarm mechanism 40 to send an alarm signal, meanwhile, a closing signal is sent to the control valve 210 to stop feeding into the tank body 10, and feeding is carried out again after field personnel overhaul the dust collector 120.
For the installation of the feeding pipe 20, a feeding hole 150 may be formed near the top of the can body 10, and one end of the feeding pipe 20 extends into the accommodating cavity 110 through the feeding hole 150 for feeding.
It should be noted that, as for the controller 310, a commercially available controller 310 may be used as the controller 310, and no modification of an internal program is required. The pressure relief valve 130, the control valve 210, the pressure sensor 320, and the alarm mechanism 40 are all selected from commercially available and directly installed components, and no modification of internal procedures or structures is required.
Therefore, in the embodiment of the present invention, the controller 310 can initialize the air pressure of the pressure relief valve 130, and the pressure sensor 320 detects the air pressure inside the can body 10 through the linear deformation of the air pressure on the column of the pressure relief valve 130. When the feeding pipe 20 continuously feeds materials into the tank body 10 and a filter element of the dust collector 120 is blocked, the air pressure input into the tank body 10 cannot be released outwards, the air pressure in the pressure safety valve 130 gradually increases, when the air pressure value is detected to be greater than or equal to the threshold value, the controller 310 controls the alarm mechanism 40 to send an alarm signal, meanwhile, the control valve 210 is closed, feeding into the tank body 10 is stopped, feeding is resumed after field personnel finish overhauling, and therefore the phenomenon that the powder tank generates ash emission or roof emission can be avoided.
