[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] Example 1

[0026] like Figure 1-4 As shown,

[0027] The dust removal system includes a dust collector 1, an ash hopper 2, an ash discharge valve 3, and a centralized ash collection pipe 4; the tobacco dust enters the ash hopper 2 through the dust collector 1, and enters the centralized ash collection pipe 4 through the ash discharge valve 3 for collection;

[0028] An online anti-blocking device for an ash hopper of a tobacco dust collector comprises a back-blowing device 5 installed on an ash hopper 2 near an ash discharge valve 3 and a control device for controlling the action of the back-blowing device 5; the control device is connected to the back-blowing device 5 by signal. The control device is provided with a timer (time module) to back-blow the connection between the ash hopper 2 and the ash discharge valve 3 at regular intervals to prevent dust from accumulating in the ash hopper 2 and causing blockage.

[0029] like Figure 3 As shown, the back-blowing device 5 includes a nozzle 51 fixedly installed on the side wall of the ash hopper 2, a main air intake pipe 52 fixedly connected to the air intake end of the nozzle 51 through an air pipe and a pipe joint, an air amplifier 53 fixedly connected to the main air intake pipe 52, and a solenoid valve 54 fixedly connected to the air amplifier 53; the solenoid valve 54 is connected to the control device signal; the solenoid valve 54 is connected to the air source 55; the air source 55 is compressed air.

[0030] like Figure 3 As shown, the cross section of the ash hopper 2 is square, and there are four nozzles 51 , which are respectively installed on the four side walls of the ash hopper 2 .

[0031] The main air intake pipe 52 is in a circular shape and surrounds the ash hopper 2 . The main air intake pipe 52 is fixedly connected to the four nozzles 51 .

[0032] The control device is a PLC controller; the controller is connected to the solenoid valve signal.

[0033] The PLC controller adopts a Siemens S7-200 controller, which is connected to the signal of the dust removal control system. A time module is provided in the controller to facilitate the timing control of the opening and closing of the solenoid valve 54.

[0034] The air amplifier 53 includes an air intake portion 534 and an amplifier portion 531 fixedly connected to the air intake portion 534; the air intake portion 534 is provided with an intake cone hole 535; the end of the amplifier portion 531 close to the air intake portion 534 is provided with a compressed air annular groove 533; the large end of the intake cone hole 535 is open, and the small end of the intake cone hole 535 is connected to the compressed air annular groove 533; the end of the amplifier portion 531 away from the air intake portion 534 is provided with a mixed gas outlet 536; the amplifier portion 531 is provided with a compressed air inlet hole 532 connected to the compressed air annular groove 533; the compressed air inlet hole 532 is connected to the solenoid valve 54 through an air pipe; the mixed gas outlet 536 is connected to the main intake pipe 52.

[0035] The compressed air flows into the compressed air annular groove 533 from the compressed air inlet hole 532, and enters the interior of the amplifier 531 along the gap between the compressed air annular groove 533 and the air inlet portion 534; due to the Venturi tube principle, a large amount of air will be sucked into the amplifier 531, and after the compressed air is mixed with the air, it flows out of the air amplifier 53 and finally enters the nozzle 51.

The dust collector control system can control the start and end time of each dust collector cleaning system. After the centralized dust collection system and the ash discharge valve 3 are opened for 5 minutes, the ash hopper 2 back-blowing system starts to work. After 10 minutes after the dust collector 1 finishes working, the ash hopper 2 back-blowing system stops working. After 25 minutes after the dust collector 1 finishes working, the ash discharge valve 3 and the centralized ash collection system stop working. Such a start and stop time setting is also a measure to prevent the ash hopper 2 from being blocked.
