[0002] The pulse bag dust collector is a new type of high-efficiency pulse bag dust collector improved on the basis of the bag dust collector. The pulse bag dust collector is widely used, wherein the smoke inlet pipe is connected to the ash hopper connected to the bottom of the pulse bag dust collector. In order to solve the problem of direct entry into the ash hopper causing local dust accumulation or severe local wear in the ash hopper, a guide device is generally provided in the ash hopper. After searching, the patent with publication number CN212881500U discloses a bag dust collector air inlet guide device, which is provided with a group of parallel guide plates on the top of the ash hopper inner cavity, and each guide plate is arranged perpendicular to the ash hopper. However, although this method can make the airflow When entering the dust collector hopper, it changes from laminar flow to turbulent flow, and then changes to laminar flow with a slower flow rate after entering the filter chamber, which optimizes the airflow distribution, improves the dust collection efficiency of the dust collector, and extends the service life of the bag. However, in actual application, when the dust collector bag on the top is being cleaned, lumps of dust are likely to fall from the dust collector bag, and are easily stuck on the top of multiple guide plates to cause accumulation. For this reason, a pulse bag dust collector hopper air inlet diversion device is designed, which is convenient for diversion and can break up the lumps that fall to the top of multiple guide plates when cleaning the dust collector bag, so that they can smoothly enter the bottom of the ash hopper, ensuring the normal operation of the air inlet diversion.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the utility model provides a pulse bag dust collector hopper air inlet guide device, which has the following beneficial effects:

When the dust bag is cleaned, the plate agglomeration breaking drive mechanism can be started to drive the multiple breaking strips to rotate as a whole, thereby breaking the plate agglomerates on the top of the vertical guide plates. The smoke is then guided downwards by the vertical guide plates to the bottom of the ash hopper, thereby preventing the smoke from accumulating and agglomerating on the vertical guide plates and affecting the airflow distribution. The smoke is guided downwards by the vertical guide plates to further ensure the uniformity of the airflow distribution.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example:

[0024] See also Figure 1-6, a pulse bag dust collector hopper air inlet guide device, includes an ash hopper 1 with a top pulse bag dust collector connection port 3 and a bottom ash cleaning port. One side of the top of the ash hopper 1 is fixedly connected to a smoke inlet pipe 2. A plurality of vertical guide plates 4 are sequentially arranged on the inner top of the ash hopper 1 along the air inlet direction of the smoke inlet pipe 2, and the top of each vertical guide plate 4 is provided with a crushing bar 5 which is in the same guide surface as the vertical guide plate 4. It also includes a plate agglomeration breaking drive mechanism for synchronously driving the plurality of crushing bars 5 to rotate, and the plurality of vertical guide plates 4 all have a downward inclination angle away from the smoke inlet pipe 2. Further, the air inlet pipe 2 can be horizontally connected to the ash hopper 1 or have a downward inclination angle which is smaller than the inclination angle of the guide plate 4.

[0025] Specifically, the tops of the multiple vertical guide plates 4 are flush, and the heights of the bottom ends of the multiple vertical guide plates 4 decrease successively in the direction away from the smoke inlet pipe 2, and the bottom end of a vertical guide plate 4 away from the smoke inlet pipe 2 is lower than the bottom end of the smoke inlet pipe 2. By lowering the bottom ends of the multiple vertical guide plates 4 successively, the airflow distribution can be made more uniform, and the impact force on the vertical guide plates 4 on the front side can be reduced.

[0026] Specifically, the multiple shredder bars 5 are fixedly connected by multiple fixed connecting rods 6, and the multiple shredder bars 5 are fixedly connected with a central axis connecting bar 7 that can rotate around the center of the pulse bag dust collector connection port 3. The multiple fixed connecting rods 6 are used to improve the overall stability of the multiple shredder bars 5. At the same time, the central axis connecting bar 7 can be driven to rotate, thereby driving the multiple shredder bars 5 to rotate around the center of the pulse bag dust collector connection port 3.

[0027] Specifically, the plate agglomeration crushing drive mechanism includes a support platform 8 fixedly installed on the top of the ash hopper 1 through two positioning connecting rods 9, and the central axis connecting bar 7 is rotatably connected to the support platform 8. It also includes a drive motor 12 fixedly installed on the top of the outer ash hopper 1. The output end of the drive motor 12 is sealed and passes through the ash hopper 1 and is fixedly connected to a drive shaft 10 extending to the top of the support platform 8. The central axis connecting bar 7 and the drive shaft 10 are connected through a transmission component. When the drive motor 12 is started, the output shaft of the drive motor 12 rotates, which facilitates the rotation of the drive shaft 10. Through the transmission cooperation of the transmission component, the central axis connecting bar 7 is conveniently driven to rotate, and then the multiple crushing bars 5 are driven to rotate as a whole.

[0028] Specifically, the transmission assembly includes two meshing bevel gears 11, one of which is fixedly connected to the middle axis connecting bar 7, and the other is fixedly connected to the drive shaft 10. A support cover 13 fixedly connected to the support platform 8 is provided on the outside of the two bevel gears 11, and the drive shaft 10 and the support cover 13 are sealed and rotated together. Through the meshing of the two bevel gears 11, when the drive shaft 10 rotates, it is convenient to drive the middle axis connecting bar 7 to rotate. Through the setting of the support cover 13, the plate agglomeration is avoided to affect the meshing of the two bevel gears 11, and the drive shaft 10 is supported.

[0029] Specifically, the vertical guide plate 4 is configured to be a wavy shape with an enlarged bottom, so as to improve the uniformity of airflow distribution.
