[0034] Figure 1 A schematic diagram of a dust removal device according to an embodiment of the present application is schematically shown. As shown in the figure, Figure 1 in an embodiment of the present application, a dust removal device 100 is provided, comprising:

[0035] Dust removal motor 101;

[0036] Delay relay 102, connected with the dust removal motor, for on-off control of the dust removal motor;

[0037] Controller 103, including a dust removal start input port and a dust removal control output port, the dust removal control output port being connected with the delay relay, the dust removal start input port being used for receiving a dust removal start signal, and the dust removal control output port being used for dust removal control according to the dust removal start signal.

[0038] The dust removal device 100 includes a dust removal motor 101, a delay relay 102, and a controller 103. The controller 103 includes a dust removal start input port and a dust removal control output port. Figure 2 As shown, a schematic diagram of a controller is provided, where G is a ground terminal, C0 is a counter number, X0 is a dust removal start input port, and Y3 is a dust removal control output port.

[0039] The dust removal control output port Y3 is connected with the delay relay 102, and the delay relay 102 is connected with the dust removal motor 101. The dust removal motor 101 can provide power for dust removal. The delay relay 102 is provided with a delay time value, which can be used for on-off control of the dust removal motor. The delay time value can be customized according to actual conditions. For example, it can be determined according to the material conveying amount and the material conveying speed, or it can be set according to actual experience.

[0040] When the material conveying vehicle reaches the material unloading area for material conveying, the user can start feeding through the feeding button. At this time, the generated dust removal start signal is fed back to the controller 103 through the dust removal start input X0, and the dust removal control output port Y3 of the controller 103 can start dust removal according to the dust removal start signal.

[0041] Specifically, the dust removal control output port Y3 of the controller 103 can control the delay relay 102 to connect the dust removal motor 101 according to the dust removal start signal, so as to realize dust removal during material conveying. When the start duration of the delay relay 102 reaches the set delay time value, the delay relay 102 is automatically disconnected, so that the circuit between the delay relay 102 and the dust removal motor 101 is disconnected, and at this time the dust removal is automatically ended.

[0042] The dust removal mode in the present scheme can include vibration dust removal or fan dust removal, and can enter the corresponding dust removal mode according to the dust removal start signal.

[0043] The dust removal device comprises a dust removal motor, a time delay relay and a controller, the time delay relay and the controller are added, the dust removal motor can be automatically turned off when the time reaches the time delay time value set by the time delay relay after the dust removal is turned on, the invalid idling of the dust removal motor for a long time is avoided, the service life of the dust removal motor is improved, and the maintenance cost of the dust removal motor is reduced.

[0044] In the embodiment of the application, the dust removal device further comprises a pressure sensor, and the controller further comprises: a feeding height signal input port connected with the pressure sensor, configured to receive a pressure signal collected by the pressure sensor, and a dust removal control output port configured to perform dust removal control according to the pressure signal.

[0045] The dust removal device 100 further comprises a pressure sensor. The pressure sensor is configured to detect the atmospheric pressure in the feeding pipe. For example, the higher the material conveying height, the greater the pressure value borne by the pressure sensor, and the lower the material conveying height, the smaller the pressure value borne by the pressure sensor. Therefore, the initial value of the pressure sensor can be set as the atmospheric pressure value, i.e., the air pressure when no material is fed into the feeding pipe, and the pressure threshold value can be set according to requirements. The pressure threshold value can be customized according to actual conditions. When performing dust removal control, the conveying height of the material in the pipe can be determined according to the pressure value collected by the pressure sensor.

[0046] The controller 103 further comprises a feeding height signal input port, Figure 2 X2 shown in FIG. 1 is a feeding height signal input port. The feeding height signal input port X2 is connected with the pressure sensor. When performing dust removal control, the pressure sensor can collect a pressure signal and feed back to the controller 103 through the feeding height signal input port X2, and the dust removal control output port Y3 of the controller 103 can determine whether to turn off the dust removal according to the pressure signal. Specifically, during the dust removal process, if the pressure value of the pressure sensor reaches the pressure threshold value, it can be determined that the material conveying is at a high material level at this time, at this time, the time delay relay 102 is automatically disconnected, so that the circuit between the time delay relay 102 and the dust removal motor 101 is disconnected, and the dust removal is automatically ended at this time.

[0047] The above scheme adds a pressure sensor, which can automatically turn off the dust removal after the dust removal is turned on, avoid the invalid idling of the dust removal motor for a long time, and improve the service life of the dust removal motor.

[0048] In the embodiment of the application, the dust removal device further comprises a feeding height meter and a feeding height sound alarm device, the feeding height signal input port is connected with the feeding height meter and configured to receive a feeding height signal collected by the feeding height meter, and the controller further comprises: a first alarm output port connected with the feeding height sound alarm device and configured to control the feeding height sound alarm device according to the feeding height signal.

[0049] The dust removal device 100 further comprises a feeding position meter and a feeding position sound alarm device. The feeding position signal input port is connected with the feeding position meter, that is Figure 2 The feeding position signal input port X2 shown in the above formula is also connected with the feeding position meter. The controller 103 further comprises a first alarm output port, Figure 2 Y1 shown in the above formula is the first alarm output port. The first alarm output port is connected with the feeding position sound alarm device.

[0050] The feeding position sound alarm device is used to give a sound alarm prompt. In the embodiment of the present application, the feeding position sound alarm device is a buzzer or a sound-light-electric bell. The buzzer can be used for high-frequency sound warning. The sound-light-electric bell can also be used for periodic sound warning.

[0051] When dust removal control is performed, the height of material conveying can be collected by the feeding position meter. The feeding position meter can collect a feeding position signal, and the feeding position signal can be fed back to the controller 103 through the feeding position signal input port X2. According to the feeding position signal, the conveying height of the material at this time can be determined. If the conveying height at this time reaches a high material position, feeding needs to be stopped. At this time, the first alarm output port Y1 can control the feeding position sound alarm device to output an alarm prompt according to the feeding position signal. If the conveying height at this time does not reach the high material position, feeding can not be stopped. At this time, the feeding position sound alarm device can not be controlled to output an alarm prompt. The high material position can be set according to requirements or the capacity of the container for material conveying.

[0052] In one embodiment, when the feeding position sound alarm device is controlled, the sound period of the alarm prompt can be set. For example, the sound period can be set to 10 seconds every 5 minutes, or can be set to 10 seconds every 2 minutes. The specific setting can be flexible according to actual requirements or actual working environment. In this way, the operation personnel can be reminded, and too much sound interference caused by the sound alarm prompt can be avoided.

[0053] The above scheme adds the feeding position sound alarm device, which can automatically control the feeding position sound alarm device according to the feeding position signal collected by the feeding position meter. The user can be timely prompted about the current material position through sound during dust removal control, so as to realize timely monitoring of the material position.

[0054] In the embodiment of the present application, the dust removal device further comprises a feeding position visual alarm device, and the controller further comprises a second alarm output port connected with the feeding position visual alarm device and used to control the feeding position visual alarm device according to the feeding position signal.

[0055] The dust removal device 100 further comprises a feeding position visual alarm device. The controller 103 further comprises a second alarm output port, Figure 2 Y0 shown in the above formula is the second alarm output port. The second alarm output port is connected with the feeding position visual alarm device.

[0056] The upper material level visual alarm device is used to send a visual alarm prompt. In the embodiment of the present application, the upper material level visual alarm device is an upper material level alarm lamp.

[0057] When dust removal control is performed, the height of material conveying can be collected by the upper material level meter. The upper material level meter can collect an upper material level signal, which can be fed back to the controller 103 through the upper material level signal input port X2. According to the upper material level signal, the conveying height of the material at this time can be determined. If the conveying height at this time reaches the high material position, the feeding needs to be stopped. At this time, the second alarm output port Y0 can control the upper material level visual alarm device to output a visual alarm prompt according to the upper material level signal. If the conveying height at this time does not reach the high material position, the feeding can not be stopped. At this time, the upper material level visual alarm device can not be controlled to output a visual alarm prompt. The high material position can be set according to requirements or the capacity of the container for material conveying.

[0058] In an embodiment, when the upper material level visual alarm device is controlled, the visual prompt period of the alarm prompt can be set. For example, the visual prompt period can be set to flash for 10 seconds every 5 minutes, or can be set to flash for 10 seconds every 2 minutes. The specific setting can be flexible according to actual requirements or actual working environment. In this way, the operation personnel can be reminded, and the surrounding working personnel will not be affected because the visual alarm prompt is too frequent.

[0059] The above scheme adds the upper material level visual alarm device, which can automatically control the upper material level visual alarm device according to the upper material level signal collected by the upper material level meter. The user can be prompted in a timely manner about the current material level through vision during dust removal control, and timely monitoring of the material level can be achieved.

[0060] In the embodiment of the present application, the controller further includes an alarm silencing input port connected with the first alarm output port, used to eliminate the sound alarm prompt.

[0061] The controller 103 further includes an alarm silencing input port. Figure 2 X1 shown in FIG. 1 is an alarm silencing input port. The alarm silencing input port X1 is connected with the first alarm output port Y1. In the case of controlling the upper material level sound alarm device to perform a sound alarm prompt according to the upper material level signal, the sound alarm prompt can be eliminated.

[0062] For example, a silencing button can be set. When the user presses the silencing button, a silencing signal generated thereby is fed back to the alarm silencing input port X1. At this time, the sound alarm prompt of the upper material level sound alarm device through the first alarm output port Y1 is eliminated.

[0063] For example, a timer can be started after the sound alarm is triggered. If the sound alarm duration reaches the preset duration, a silencing signal can be generated and sent to the alarm silencing input port X1, which in turn can eliminate the sound alarm of the material loading sound alarm device through the first alarm output port Y1.

[0064] As described above, the dust removal device may include a single audible alarm device for the material loading level, a single visual alarm device for the material loading level, or both a audible alarm device and a visual alarm device for the material loading level. When a audible alarm device for the material loading level is included, its audible alarm prompts can be eliminated.

[0065] The controller includes a first alarm output port and a second alarm output port, which separately controls the audible alarm and the visual alarm. The audible alarm can be turned off independently, and the audible alarm can be reset and restarted when the visual alarm stops. This avoids the risk of the high level gauge not working during the next feeding due to the user manually turning off the audible alarm device.

[0066] In this embodiment of the application, the dust removal device further includes a discharge level gauge and a feed indicator light. The controller further includes: a discharge level signal input port, connected to the discharge level gauge, for receiving the discharge level signal collected by the discharge level gauge; and a feed output port, connected to the feed indicator light, for controlling the feed indicator light according to the discharge level signal.

[0067] The dust removal device 100 also includes a discharge level gauge and a feed indicator light. The discharge level gauge is used to collect the height of the material being conveyed. The feed indicator light is used to indicate when the material is being fed. The controller 103 also includes a discharge level signal input port and a feed output port. Figure 2 X3 shown is the unloading position signal input port. Figure 2 Y2 in the diagram refers to the feed output port. The unloading position signal input port X3 is connected to the unloading position gauge. The feed output port Y2 is connected to the feed indicator light.

[0068] During dust control, the material conveying height can be collected using a level gauge. The level gauge collects the material level signal, which is fed back to the controller 103 via the level signal input port X3. Based on the level signal, the current material conveying height can be determined. If the conveying height reaches the low-level alarm position, a feeding reminder is required. In this case, the feeding output port Y2 can control the feeding indicator light to output a feeding prompt based on the level signal. If the conveying height has not reached the low-level alarm position, no feeding reminder is needed. In this case, the feeding indicator light does not need to output a feeding prompt. The low-level alarm position can be set according to requirements or the capacity of the material conveying container.

[0069] In one embodiment, when the feeding instruction light is controlled, the reminding period of the feeding prompt can be set. For example, the reminding period can be set as 3s reminding every 2 minutes, or 5s reminding every 3 minutes, which can be flexibly set according to actual needs or actual working environment.

[0070] The above scheme adds a feeding instruction light, which can automatically control the feeding instruction light according to the discharge position signal collected by the discharge position meter, can timely prompt the user of the current material position during the dust removal control process, and realizes timely monitoring of the material position.

[0071] As shown in Figure 3 Fig. 1, a schematic diagram of a dust removal method is provided, which includes the following steps:

[0072] Step 1: When the powder conveying vehicle arrives at the specified position and starts powder conveying, start the feeding button and enter PLC control.

[0073] Step 2: Set the time value of the delay relay, the switch threshold value of the pressure sensor, and start the high material position meter monitoring in the PLC, and start the feeding button display light (the material position light in the figure).

[0074] Step 3: Determine whether to automatically close the high material position meter monitoring and the dust removal system by judging whether the time value of the delay relay and the pressure detected by the pressure sensor reach the target value.

[0075] Step 4: When the pressure sensor value is greater than a certain value or the time value of the delay relay reaches a certain value, the dust removal system is automatically closed; at the same time, when the high material position meter monitoring shows that the feeding has reached the high material position, the feeding is immediately stopped, and the alarm light and the buzzer are prompted to alarm, and the working time of the buzzer is set to 10s every 5 minutes, and the high material position meter monitoring is closed after the alarm is started; during the alarm prompt, the alarm light and the buzzer are separately controlled, the buzzer can be separately closed, and the high material position alarm light is reset after the high material position alarm light stops flashing.

[0076] Step 5: Turn off the feeding button display light and turn on the low material position meter monitoring, and when the material position reaches the low position alarm position, the material position light is turned on and the feeding is reminded.
