[0018] Preferably, a support plate is fixedly connected to the inner wall of the dust removal box, and the support plate is slidably connected to the strip plate.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0033] like Figure 1-Figure 7 As shown, the utility model provides a bag dust collector, including a dust box 1, the lower surface of the dust box 1 is fixed and connected with an ash storage hopper 2, the lower end of the ash storage hopper 2 is installed with a control valve 3, the side wall of the dust box 1 is fixed and connected with an air inlet pipe 4, the upper surface of the dust box 1 is fixedly connected with a fan 5, the upper surface of the dust box 1 is fixed and connected with an exhaust pipe 6, one end of the exhaust pipe 6 is fixedly connected and connected with the air inlet end of the fan 5, the inner wall of the dust box 1 is fixedly connected with a mounting plate 7, a plurality of bag tubes 10 are slidably connected in the mounting plate 7, the inner wall of the dust box 1 is provided with a vibration structure 8, and the inner wall of the dust box 1 is provided with an auxiliary structure 9.

[0034] The specific configuration and function of the vibration structure 8 and the auxiliary structure 9 will be described in detail below.

[0035] like Figure 2-Figure 5As shown, the vibration structure 8 includes an extension plate 801, which is fixedly connected to the inner wall of the dust removal box 1, and a plurality of springs 802 are fixedly connected to the upper surface of the extension plate 801, one end of the spring 802 is fixedly connected to a connecting frame 803, and an impact plate 804 is fixedly connected to the upper surface of the connecting frame 803. A rotating rod 805 is rotatably connected in the dust removal box 1, and a driving plate 807 is fixedly connected to the arc surface of the rotating rod 805. A motor 806 is fixedly connected to the outer wall of the dust removal box 1, and the output end of the motor 806 is fixedly connected to the rotating rod 805. A transmission plate 808 is fixedly connected to the lower surface of the connecting frame 803, and two limit plates 809 are fixedly connected to the surface of the extension plate 801. The transmission plate 808 slides through the limit plate 809, and the limit plate 809 reaches a limit on the sliding path of the transmission plate 808, thereby limiting the connection frame 8 03 The role of the sliding path, the driving plate 807 is slidably connected with a card plate 810, and the surface of the card plate 810 is fixedly connected with a wear-resistant plate 811, which is made of polyamide resin. The wear-resistant plate 811 made of polyamide resin can improve the wear resistance of the driving plate 807 while reducing the friction between the driving plate 807 and the transmission plate 808. The driving plate 807 is internally threaded with a bolt 812, and the bolt 812 passes through the driving plate 807 and abuts against the surface of the card plate 810. When the bolt 812 abuts against the surface of the card plate 810, the bolt 812 reaches the position of the card plate 810, thereby limiting the position of the wear-resistant plate 811. A transparent plate 813 is embedded in the dust removal box 1, and the transparent plate 813 can facilitate the observation of foreign matter adhesion on the surface of the bag tube 10, thereby facilitating and timely cleaning of the bag tube 10.

[0036] like Figure 6 and Figure 7 As shown, the auxiliary structure 9 includes a perforated plate 91, which is fixedly connected to the dust removal box 1, and a strip plate 92 is slidably connected inside the dust removal box 1. A sealing plate 93 is fixedly connected to the surface of the strip plate 92, and the sealing plate 93 is slidably connected to the perforated plate 91. The size of the sealing plate 93 is matched with the size of the perforated plate 91. An electric push rod 94 is fixedly connected to the outer wall of the dust removal box 1, and the output end of the electric push rod 94 is fixedly connected to the strip plate 92. A support plate 95 is fixedly connected to the inner wall of the dust removal box 1, and the support plate 95 is slidably connected to the strip plate 92. During the sliding process of the strip plate 92, the support plate 95 can support the strip plate 92, so that the sealing plate 93 can stably seal the perforated plate 91.

[0037] The overall working principle is that when it is necessary to treat the exhaust gas in the grain processing process, the exhaust gas is passed into the air intake pipe 4, and then the fan 5 is turned on. The fan 5 will suck air, and the exhaust gas will flow into the dust removal box 1 through the air intake pipe 4, and then the exhaust gas will flow through the bag tube 10. At this time, the bag tube 10 will filter the exhaust gas, and foreign matter such as dust or bran in the exhaust gas will be blocked on the outer wall of the bag tube 10, and the purified air will flow upward into the exhaust pipe 6, and then be discharged by the fan 5. When it is necessary to clean foreign matter such as dust or bran attached to the outer wall of the bag tube 10, the motor 806 is turned on, and the rotation of the output end of the motor 806 will drive the rotating rod 805 to rotate The rotation of the rotating rod 805 will drive the driving plate 807 to rotate, the rotation of the driving plate 807 will drive the card plate 810 to move, the movement of the card plate 810 will drive the wear-resistant plate 811 to move, when the wear-resistant plate 811 contacts the transmission plate 808, the transmission plate 808 will be squeezed and slide downward, at this time, the wear-resistant plate 811 made of polyamide resin can improve the wear resistance of the driving plate 807 while reducing the friction between the driving plate 807 and the transmission plate 808, the sliding of the transmission plate 808 will drive the connecting frame 803 to slide, in this process, the limit plate 809 reaches the limit of the sliding path of the transmission plate 808, thereby limiting the sliding path of the connecting frame 803 The sliding of the connecting frame 803 will drive the impact plate 804 to move so that the impact plate 804 is out of contact with the bag tube 10. At the same time, the spring 802 will also be compressed by the connecting frame 803. The driving plate 807 continues to rotate to make the wear-resistant plate 811 out of contact with the transmission plate 808. At this time, the spring 802 begins to stretch, and the connecting frame 803 will slide upward quickly with the help of the tension of the spring 802. The sliding of the connecting frame 803 will drive the impact plate 804 to slide. After the impact plate 804 hits the bag tube 10, the bag tube 10 will vibrate, thereby making foreign matter such as dust or chaff attached to the surface of the bag tube 10 fall off, so as to clean the bag tube 10 and prevent dust or chaff from sticking to the bag tube 10. The situation where foreign objects such as leather block the bag tube 10 occurs, which improves the dust removal efficiency. When the wear-resistant plate 811 needs to be replaced, the bolt 812 is rotated to make the bolt 812 disengage from the card plate 810, and then the old wear-resistant plate 811 is removed, and the card plate 810 with the new wear-resistant plate 811 is inserted into the driving plate 807, and then the bolt 812 is rotated in the opposite direction. When the bolt 812 is against the surface of the card plate 810, the bolt 812 reaches the position of the card plate 810, thereby limiting the position of the wear-resistant plate 811. The transparent plate 813 can facilitate the observation of foreign matter adhesion on the surface of the bag tube 10, thereby facilitating and timely cleaning of the bag tube 10.

[0038] When the exhaust gas enters the air inlet pipe 4, the output end of the control electric push rod 94 is extended. At this time, the electric push rod 94 will drive the strip plate 92 to slide along the dust removal box 1. The sliding of the strip plate 92 will drive the blocking plate 93 to slide. The sliding of the blocking plate 93 will block the orifice plate 91. At this time, the exhaust gas cannot blow away the dust or chaff and other foreign matter in the ash storage hopper 2, thereby preventing the dust or chaff and other foreign matter in the ash storage hopper 2 from spreading again and increasing the filtering pressure of the bag tube 10. The dust generated during the dust removal process Foreign matter such as dust or chaff will fall on the upper surface of the orifice plate 91 and the sealing plate 93. After the dust removal is completed, the output end of the electric push rod 94 is controlled to shrink. At this time, the sealing plate 93 no longer blocks the orifice plate 91. Therefore, foreign matter such as dust or chaff on the upper surface of the orifice plate 91 and the sealing plate 93 will fall through the orifice plate 91 into the ash storage hopper 2 for storage. During the sliding process of the strip plate 92, the support plate 95 can support the strip plate 92, so that the sealing plate 93 can stably seal the orifice plate 91.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
