In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0046] Furthermore, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0047] Example 1

[0048] Reference Figure 1-2 , this embodiment provides a dust collector ash hopper for flue gas desulfurization and denitrification.

[0049] The ash hopper of the dust collector for flue gas desulfurization and denitrification comprises an ash hopper mechanism 100 and a duct control mechanism 200 .

[0050] Specifically, the ash hopper mechanism 100 includes an ash hopper body 101 arranged in a funnel shape, and a matching upper conduit 102 is sleeved on the inner side of the bottom of the ash hopper body 101, and a lower conduit 103 is also sleeved on the inner side of the lower part of the upper conduit 102. At the same time, two groups of leveling parts 104 are symmetrically arranged on the two outer side walls of the upper conduit 102 about its own center point, and a placement chamber 105 is also connected to both sides of the ash hopper body 101.

[0051] The duct control mechanism 200 is installed in the placement chamber 105 on both sides of the ash hopper body 101, and specifically includes a roller member 201 hoisted inside the placement chamber 105, and a pushing member 202 is embedded inside the roller member 201, and the front end of the pushing member 202 extends to the outer wall of the ash hopper body 101, and a lifting member 203 is also sleeved at the end of the pushing member 202, and a connecting member 204 is installed inside the lifting member 203, and one end of a cable 205 is fixedly wound around the periphery of the lifting member 203, and the other end of the cable 205 is connected to the lower duct 103, and the middle section of the cable 205 is also installed with a guide member 206 fixed to the inner wall of the ash hopper body 101, the guide member 206 can guide the cable 205, reduce the wear of the cable 205 during movement, and prevent the cable 205 from contacting the ash hopper mechanism 100.

[0052] Furthermore, the inner edge of the bottom of the hopper body 101, the upper and lower parts of the upper duct 102 and the lower duct 103 are all provided with convex edges, which can ensure a stable connection between the three while satisfying the up and down movement of the upper duct 102 and the lower duct 103. At the same time, with the setting of the outer convex edge at the bottom of the lower duct 103, when the lower duct 103 moves upward, the outer convex edge can contact the bottom of the upper duct 102, and synchronously drive the upper duct 102 to rise through the rise of the lower duct 103, thereby realizing height adjustment of the upper duct 102 and the lower duct 103.

[0053] During specific use, when the smoke inside the dust collector is discharged through the ash hopper body 101, it can contact the roller member 201 under the action of gravity and drive the roller member 201 to rotate, and then the pushing member 202 inside the roller member 201 extends out and cooperates with the connecting member 204 inside the lifting member 203 to control the connection state of the lifting member 203 and the roller member 201, so that the lifting member 203 can intermittently rotate synchronously with the roller member 201, and then by winding the cable 205, the lower duct 103 and the upper duct 102 are lifted in sequence, and by adjusting the height of the ash hopper mechanism 100, the falling of the smoke can be facilitated to prevent the smoke from accumulating to a certain height when discharged and blocking the lower duct 103.

[0054] Example 2

[0055] Reference Figure 1-6 , which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0056] The leveling member 104 includes a vertically arranged upright pole 104a, and guide blocks 104b and slide posts 104c are integrally arranged on both sides of the top of the upright pole 104a, and a leveling plate 104d is integrally connected to the bottom of the upright pole 104a.

[0057] Furthermore, horizontal guide grooves 101a are provided at the bottom of the inner walls on both sides of the hopper body 101, and inclined grooves 102a are provided on both sides of the outer wall of the upper conduit 102. The two inclined grooves 102a are also symmetrically arranged about the center of the upper conduit 102. The vertical rod 104a is clamped between the hopper body 101 and the upper conduit 102. At the same time, the guide block 104b and the slide column 104c are respectively slidably embedded in the guide groove 101a and the inclined groove 102a. When the inclined groove 102a rises with the rise of the upper conduit 102 and the slide column 104c is released, the inclined groove 102a is lifted and lowered. When relative movement occurs, through the inclined setting of the inclined groove 102a, the groove wall can generate a pushing force on the sliding column 104c, so that the sliding column 104c can drive the entire leveling piece 104 to move. At the same time, with the cooperation of the guide groove 101a and the guide block 104b, the horizontal guide groove 101a guides the movement of the leveling piece 104, so that when the upper guide tube 102 moves upward, the leveling pieces 104 on both sides can move synchronously horizontally toward each other, so as to level the smoke and dust pile, so as to facilitate the smooth falling of the subsequent smoke and dust.

[0058] Example 3

[0059] Reference Figure 1-11 , which is the third embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0060] The roller member 201 includes a turning cylinder 201a which is arranged inside when placed. The inner side of the turning cylinder 201a is arranged in an impeller shape, and both ends of the turning cylinder 201a are rotatably matched with main hangers 201b, and the two main hangers 201b are fixed to the top of the placement chamber 105, thereby realizing the fixed lifting of the turning cylinder 201a, and the center of the turning cylinder 201a is hollow, and a rotating groove 201c is arranged on its inner wall. At the same time, a control panel 201d is fixedly arranged on one end surface of the turning cylinder 201a, and the control panel 201d extends to the outside of the ash hopper body 101, and the rotation of the turning cylinder 201a can be manually controlled by the control panel 201d.

[0061] The pushing member 202 includes a pushing platform 202a located inside the flip cylinder 201a, and a pushing column 202b is arranged on the outside of the pushing platform 202a, and the end surface of the pushing platform 202a is integrally connected with a transmission column 202c, and the outside of the transmission column 202c is also coaxially sleeved with multiple groups of pushing teeth 202d, and the outer wall of the pushing platform 202a is also provided with a positioning groove 202e.

[0062] The winding lifting member 203 includes a winding drum 203a suspended inside the placement chamber 105, and a secondary hanger 203b is provided on both end surfaces of the winding drum 203a, and the winding drum 203a is fixed to one side of the reversing drum through the secondary hanger 203b.

[0063] The connecting member 204 includes a telescopic plate 204a movably arranged inside the winding disk 203a, and the telescopic plate 204a is respectively fixed with a fixed head 204b and a linkage head 204c at both ends of the axial direction of the winding disk 203a, and the telescopic plate 204a is provided with a tooth plate 204d along one side of the radial direction of the winding disk 203a, and the outer side of the tooth plate 204d is matched with a transmission tooth 204e, and the transmission tooth 204e is also arranged in the winding disk 203a, wherein the edge of the transmission tooth 204e extends to the inner edge of the winding disk 203a, and a return spring 204f is also provided on the other side of the telescopic plate 204a, and the two ends of the return spring 204f are respectively abutted against the telescopic plate 204a and the winding disk 203a, thereby playing a role of elastic support for the telescopic plate 204a, ensuring the rapid reset of the telescopic plate 204a after movement.

[0064] The guide member 206 includes a U-shaped guide frame 206 a fixed to the inner wall of the ash hopper body 101 , and a guide wheel 206 b that can fit with the cable 205 is installed on the outside of the middle section of the guide frame 206 a .

[0065] Furthermore, a notch 105a matching with the push column 202b is provided on the outer side of the ash hopper body 101, and a protrusion 105b is provided on the inner edge of the notch 105a. At the same time, the protrusion 105b is movably embedded in the positioning groove 202e on the outer side of the push column 202b. Through the interlocking setting between the protrusion and the positioning groove 202e, the push column 202b can only perform axial horizontal movement without radial movement.

[0066] The rotating groove 201c includes a push groove 201c-1 which is spirally arranged along the inner wall of the turning cylinder 201a. The end of the push groove 201c-1 is connected with an annular groove 201c-2. The push groove 201c-1 and the annular groove 201c-2 are both matched with the push column 202b. At the same time, a guide piece 201c-3 for guiding the movement of the push column 202b is installed inside the annular groove 201c-2. The guide piece 201c-3 can only be moved in one direction. When the turning cylinder 201a rotates under the action of the gravity of the smoke and dust, the push groove 201c-1 inside it can rotate synchronously. At this time, under the action of the groove wall of the push groove 201c-1 on the push column 202b which can only move horizontally, the transmission column 202c and the push platform 202a can be synchronously gradually moved from the turning cylinder 201a to the horizontal push column 202b. 1a extends out, thereby achieving the purpose of extending the pushing member 202 to cooperate with the winding member 203 and the connecting member 204. At the same time, when the pushing column 202b rotates and moves to the annular groove 201c-2 section, the flip cylinder 201a is free to rotate at this time, and will not affect the position of the pushing member 202. If the pushing member 202 is to return to the starting end of the pushing groove 201c-1, the flip cylinder 201a can be rotated in the opposite direction through the control disk 201d. When the pushing column 202b moves to the guide piece 201c-3, it can return to the pushing groove 201c-1 under the guidance of the one-way piece that is unidirectionally moved. Finally, the pushing member 202 can be reset with the reverse rotation of the flip cylinder 201a, so as to facilitate the subsequent use of the ash hopper body 101.

[0067] Preferably, multiple groups of pushing teeth 202d are arranged in a linear array about the transmission column 202c, and the multiple groups of pushing teeth 202d are composed of a plurality of tooth plates 202d-1. The transmission teeth 204e can respectively mesh with the tooth plate 204d and the pushing teeth 202d, so that when the multiple groups of pushing teeth 202d intermittently mesh with the transmission teeth 204e as the transmission column 202c extends, the telescopic plate 204a can be intermittently reciprocated under the joint action of the intermittent transmission of the transmission teeth 204e and the return spring 204f, so as to achieve the purpose of controlling the movement state of the winding disk 203a through intermittent engagement between the fixed heads 204b and the linkage heads 204c at both ends of the telescopic plate 204a and the fixed holes 105c and the linkage holes 201e, thereby realizing the step-by-step rise of the upper guide tube 102 and the lower guide tube 103 by intermittently winding up the cable 205.

[0068] A fixing hole 105c is provided on the inner wall of the placement chamber 105, and a linkage hole 201e is provided on the end surface of one side of the pusher 202 of the flip cylinder 201a, and a plurality of fixing holes 105c and linkage holes 201e are arranged at equal angles. The fixing heads 204b and linkage heads 204c at both ends of the telescopic plate 204a can be respectively engaged with the fixing holes 105c and the linkage heads 204c. When the pushing teeth 202d on the transmission column 202c contact the transmission teeth 204e, the telescopic plate 204a can be moved toward the linkage hole 201e under the transmission of the transmission teeth 204e, and the linkage heads 204c are inserted into the linkage holes. At the same time as 201e, the winding disk 203a rotates synchronously with the flip cylinder 201a, and the cable 205 is wound at this time, so as to realize the pulling up of the lower guide tube 103. With the movement of the transmission column 202c, the pushing tooth 202d is gradually separated from the transmission tooth 204e. At this time, the transmission force exerted on the telescopic plate 204a disappears, and it can be reset under the elastic force of the reset spring 204f, so that the fixed head 204b moves to the fixed hole 105c, so as to achieve the purpose of locking the winding disk 203a, thereby realizing the step-by-step lifting of the upper guide tube 102 and the lower guide tube 103 to meet the falling needs of the smoke and dust.

[0069] During specific use, the gravity of the falling smoke drives the roller member 201 to rotate, thereby causing the pushing member 202 to move outward, and as the pushing member 202 moves outward, the multiple groups of pushing teeth 202d outside the transmission column 202c are meshed with the transmission teeth 204e in sequence, and then the cooperation between the transmission teeth 204e and the tooth plate 204d allows the telescopic plate 204a to be intermittently telescoped, thereby achieving the purpose of controlling the locking state between the winding disk 203a and the turning cylinder 201a or the ash hopper body 101. When the winding disk 203a is locked with the turning cylinder 201a, it can rotate synchronously with the turning cylinder 201a to reel the cable 205, thereby causing the upper guide tube 102 and the lower guide tube 103 to rise, and when the winding disk 203a is locked with the ash hopper body 101, the cable 205 is reeled in. The disk 203a is stationary and the flip cylinder 201a rotates normally. At this time, the winding of the cable 205 stops, the upper guide tube 102 and the lower guide tube 103 stop rising, and at the same time, the opening angle between the multiple fixed holes 105c and the linkage hole 201e is matched with the movement of the telescopic plate 204a, that is, when the pushing tooth 202d contacts the transmission tooth 204e, the telescopic plate 204a moves synchronously to the linkage hole 201e in the rotating state, and is smoothly plugged in, completing the linkage locking between the winding disk 203a and the flip cylinder 201a, and when the pushing tooth 202d is separated from the transmission tooth 204e, the telescopic plate 204a is quickly reset under the push of the reset spring 204f, and is smoothly plugged into the fixed holes 105c at different angles along with the rotation of the winding disk 203a, ensuring the stable use of the winding disk 203a. By setting the duct control mechanism 200, the duct at the bottom of the ash hopper body 101 can change in height as the smoke accumulates, thereby slowing down the speed at which the top of the smoke pile blocks the bottom of the ash hopper body 101, maximizing the single-time exhaust volume of smoke, and reducing the frequency of users cleaning and transferring the smoke pile.
