[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, 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.

[0032] Example 1, reference Figures 1 to 3 , which is the first embodiment of the present invention, provides an ash silo drainage device, including a accommodating mechanism 100, a filtering mechanism 200 arranged in the accommodating mechanism 100, and a vibrating mechanism 300 arranged on the filtering mechanism 200; the accommodating mechanism 100 includes a accommodating box 101, a water inlet trough 102 and a side plate 103 arranged on the accommodating box 101; the vibrating mechanism 300 includes an active component 301 arranged in the filtering mechanism 200, and a trigger component 302 arranged between the accommodating box 101 and the active component 301.

[0033] Specifically, the configuration of the containing mechanism 100 facilitates better protection of its internal components and can better prevent external ash water from contacting the motor 201. The cross-section of the containing mechanism 100 is rectangular. The configuration of the filtering mechanism 200 facilitates better filtering of the water in the ash bin to achieve the effect of separating water and coal slag. The configuration of the vibration mechanism 300 facilitates better driving the filtering mechanism 200 to vibrate and achieves the effect of shaking off the coal powder on the filtering mechanism 200. The configuration of the movable component 301 and the trigger component 302 enables the vibration mechanism 300 to be started when the motor 201 rotates forward and fails when it rotates reversely. The rotation direction of the motor 201 can be selected according to the change of the received water flow. Within a period of time after the ash bin is watered, the water flow received by the device increases, and then gradually decreases until the next watering operation is carried out.

[0034] The filtering mechanism 200 includes a motor 201 arranged inside the accommodating box 101, a filter cartridge 202 arranged at the driving end of the motor 201, circular plates 203 and mounting plates 204 are provided at both ends of the filter cartridge 202, and a pushing arc bar 205 is provided between the circular plate 203 and the mounting plate 204. The driving end of the motor 201 is fixedly connected to the filter cartridge 202 through the circular plate 203, and the inner wall of the pushing arc bar 205 is in contact with the inner wall of the filter cartridge 202. There are multiple pushing arc bars 205, and the multiple pushing arc bars 205 are distributed in a circular array around the filter cartridge 202.

[0035] Furthermore, the setting of the motor 201 facilitates better control of the rotation direction of the filter mechanism 200. The motor 201 is electrically connected to an external power supply. The motor 201 is an existing device and will not be described here. The cross-section of the filter cartridge 202 is circular. The filter cartridge 202 is fixedly connected to the circular plate 203. The circular plate 203 is fixedly connected to the push arc bar 205. The push arc bar 205 is made of stainless steel. The setting of the push arc bar 205 can effectively guide the coal powder at the top of the filter cartridge 202 away from the side of the device to prevent the coal powder from accumulating on the top of the filter cartridge 202 and damaging the operation of the filter cartridge 202.

[0036] In summary, the setting of the accommodating mechanism 100 can better prevent external gray water from contacting the motor 201, the cross-section of the pushing arc bar 205 is circular, and the setting of multiple annular pushing arc bars 205 can effectively guide the coal powder located on the top of the filter cartridge 202 to one side away from the device, thereby preventing the coal powder from accumulating above the filter cartridge 202 and damaging the operation of the filter cartridge 202. A rubber pad layer is provided on the inner wall of the water inlet trough 102 to increase the sealing between the pushing arc bar 205 and the water inlet trough 102, and a drainage groove is provided on the side of the accommodating box 101.

[0037] Example 2, reference Figure 2-5 , which is the second embodiment of the present invention. The difference from the previous embodiment is the movable component 301, which includes a through hole 301a arranged in the middle of the mounting plate 204, a rotating box 301b arranged in the through hole 301a, and an external hole 301c arranged in the rotating box 301b. A docking frame 301d and an external bracket 301e are arranged outside the rotating box 301b, and an internal hole 301f is arranged between the docking frame 301d and the external bracket 301e. The internal hole 301f located inside the docking frame 301d is respectively fixedly connected to the limit rod 301g and the reset spring 301h, and the other end of the reset spring 301h is fixedly connected to the docking frame 301d.

[0038] Specifically, the cross section of the docking frame 301d is "T" shaped, and the setting of the docking frame 301d can effectively connect the trigger assembly 302 with the external structure. The cross section of the through hole 301a is circular, and the through hole 301a is at the same position as the center point of the mounting plate 204. The cross section of the rotating box 301b is circular, and the cross section of the external hole 301c is circular. There is a gap between the docking frame 301d and the external bracket 301e, and the cross section of the built-in hole 301f is circular. The setting of the built-in hole 301f is convenient for adding a gap between the docking frame 301d and the external bracket 301e. The components are arranged to control the distance and relative position between the docking frame 301d and the external bracket 301e. The limit rod 301g is made of stainless steel. The setting of the limit rod 301g is convenient for better limiting the external bracket 301e. The reset spring 301h can effectively control the distance between the external bracket 301e and the docking frame 301d. When the external bracket 301e moves toward the docking frame 301d, the reset spring 301h contracts and accumulates elastic potential energy, and can effectively drive the external bracket 301e to reset when the external force is lost.

[0039] The through hole 301a is rotatably connected to the rotating box 301b. The cross sections of the rotating box 301b and the through hole 301a are both circular. The docking frame 301d is in contact with the outer wall and the inner wall of the return spring 301h.

[0040] Furthermore, the cross section of the rotating box 301b is annular, and the provision of the through hole 301a can effectively limit the rotating box 301b, and the docking frame 301d is fixedly connected to the rotating box 301b.

[0041] The movable assembly 301 further includes a roller 301i disposed on an external bracket 301e, a base 301j and a contact worm frame 301k disposed between the mounting plate 204 and the roller 301i, and a guide piece 301l is disposed between the contact worm frame 301k and the base 301j.

[0042] Preferably, the setting of the outer wall of the roller 301i and the base 301j can effectively support the external bracket 301e, and the setting of the abutting vortex frame 301k can enable the external bracket 301e to move toward the docking frame 301d under the limiting action of the roller 301i during the movement, the abutting vortex frame 301k is fixedly connected to the mounting plate 204, and the abutting vortex frame 301k is fixedly connected to the guide piece 301l. The setting of the guide piece 301l can effectively guide the roller 301i located at the base 301j to the abutting vortex frame 301k, the roller 301i is rotatably connected to the external bracket 301e through a bearing, the guide piece 301l is in contact with the base 301j, the inner wall of the guide piece 301l is in contact with the outer wall of the bottom of the roller 301i, and the outer wall of the base 301j is in arc shape and in contact with the roller 301i.

[0043] The rest of the structure is the same as that of Example 1.

[0044] During use, in order to prevent dust from overflowing, water will be sprinkled in the ash bin to reduce dust. Saturated water is generally used for sprinkling. After the ash bin is sprinkled with water, the ash water will accumulate in the water storage of the ash bin for a period of time. When there is a lot of water in the water storage, it needs to be discharged. When the water sprinkling starts, the motor 201 rotates forward to drive the movable component 301 and the trigger component 302 to operate, so that the vibration mechanism 300 is started when the motor 201 rotates forward. The vibration mechanism 300 drives the filter cartridge 202 to vibrate while running, so that the ash water can be effectively filtered to prevent the impurities remaining on the filter cartridge 202 from affecting the filtering effect.

[0045] When the watering is finished, the water storage is in a seepage state, with less water and no need for rapid filtration. In order to save energy, the motor 201 is reversed. When the motor 201 is reversed, the vibration mechanism 300 fails, and the motor 201 drives the filter cartridge 202 to idle to simply filter the gray water.

[0046] In summary, the setting of the limit rod 301g facilitates better limiting of the external bracket 301e, the reset spring 301h can effectively control the distance between the external bracket 301e and the docking bracket 301d, the setting of the outer wall of the roller 301i and the base 301j can effectively support the external bracket 301e, and the setting of the abutment vortex frame 301k can enable the external bracket 301e to move toward the docking bracket 301d under the limiting action of the roller 301i during the movement.

[0047] Example 3, reference Figures 1 to 7 , which is the third embodiment of the present invention. The difference from the previous embodiment is the trigger assembly 302. The trigger assembly 302 includes a rotating block 302a arranged in the external hole 301c, the rotating block 302a is fixedly connected to the accommodating box 101, and a side block 302b is arranged on the rotating block 302a. The side blocks 302b have slope surfaces 302c and stop surfaces 302d on both sides.

[0048] Specifically, the setting of the trigger component 302 facilitates better control of the activation of the filter mechanism 200. When the motor 201 in the device rotates forward, the trigger component 302 is activated, thereby driving the vibration mechanism 300 to work, achieving the effect of vibration, vibrating the filter cartridge 202, and achieving the effect of vibrating the material to avoid material blockage. When reversed, the trigger component 302 is not activated, thereby rendering the vibration mechanism 300 invalid. At this time, the power consumption of the motor 201 decreases, which is beneficial to saving energy. The rotation direction of the motor 201 can be selected according to the changes in the received water flow.

[0049] The trigger assembly 302 also includes an external rotating rod 302e and an internal rotating rod 302f rotatably disposed in the rotating box 301b, a top bar 302g and a side bar 302h fixedly disposed in the rotating box 301b, a hanging bracket 302i is disposed outside the internal rotating rod 302f, one side of the hanging bracket 302i is arc-shaped, a bottom block 302j is fixedly connected to the bottom of the hanging bracket 302i, a receiving surface 302k and a plane 302l are respectively disposed on both sides of the bottom block 302j, and a receiving groove is disposed on the inner wall of the rotating box 301b. The outer wall of the internal rotating rod 302f is fitted with the inner wall of the hanging bracket 302i, the external rotating rod 302e and the internal rotating rod 302f are both rotatably connected to the rotating box 301b, and the receiving surface 302k and the plane 302l correspond to the slope surface 302c and the stopping surface 302d respectively.

[0050] Furthermore, the external rotating rod 302e and the internal rotating rod 302f are both composed of a positioning rod and a cylinder rotatably connected to the rod. When working, the external component contacts the external rotating rod 302e and the internal rotating rod 302f, which rotates to reduce friction. The cross section of the top bar 302g is "L"-shaped. The top bar 302g can effectively resist the hanging bracket 302i, thereby preventing the hanging bracket 302i from contacting the rotating box 301b and slipping off. The hanging bracket 302i is located between the top bar 302g and the side bar 302 h can be effectively limited, the setting of the embedded groove is convenient for better limiting the hanger 302i, preventing the hanger 302i from slipping during the movement, so as to better limit the hanger 302i and the bottom block 302j, the receiving surface 302k and the slope 302c are both arc surfaces, the slope 302c can effectively drive the bottom block 302j to move, and the setting of the stopping surface 302d can effectively drive the bottom block 302j and the hanger 302i to move under the limiting action of the plane 302l.

[0051] The rest of the structure is the same as that of Example 2.

[0052] When in use, the motor 201 rotates, and the circular plate 203 and the filter cartridge 202 are driven to rotate during the rotation of the motor 201. The filter cartridge 202 is driven to rotate the mounting plate 204 during the rotation of the mounting plate 204. The rotation of the mounting plate 204 drives the base plate, the guide sheet 3011, and the vortex frame to rotate, so that the guide sheet 3011 applies pressure to the roller 301i, causing the roller 301i to rotate. The torsional force of the roller 301i is transmitted to the external bracket 301e and the docking bracket 301d, and the docking bracket 301d The torsional force is transmitted to the rotating box 301b. After the rotating box 301b rotates slightly, the stop surface 302d contacts the plane 302l. After the plane 302l is squeezed, the other end of the hanging bracket 302i contacts the top bar 302g, so that the top bar 302g contacts the hanging bracket 302i. At this time, the external rotating rod 302e is limited by the hanging bracket 302i, so that the rotating box 301b stops rotating. The rotating box 301b stops rotating, which drives the docking frame 301d and the external bracket 301e to stop rotating.

[0053] At this time, the guide sheet contacts the roller 301i, causing the roller 301i to move toward the docking frame 301d, and the roller 301i drives the external bracket 301e to squeeze the return spring 301h, and the return spring 301h contracts to accumulate elastic potential energy. When the roller 301i completely passes through the contact vortex frame 301k, the roller 301i is not contacted, and the elastic potential energy of the return spring 301h is released, driving the roller 301i to reset. When the roller 301i is reset, it impacts the base 301j. After the base 301j is impacted, it drives the filter cartridge 202 to vibrate, thereby vibrating out the dust on the filter cartridge 202, achieving an effective filtering effect.

[0054] When the motor 201 is reversed, the motor 201 drives the circular plate 203 to rotate. During the rotation of the circular plate 203, the filter cartridge 202 is driven to rotate. During the rotation of the filter cartridge 202, the mounting plate 204 is driven to rotate. The rotation of the mounting plate 204 drives the base plate, the guide sheet 3011 and the vortex frame to rotate, so that the guide sheet 3011 applies pressure to the roller 301i, causing the roller 301i to rotate. The torsional force of the roller 301i is transmitted to the external bracket 301e and the docking bracket 301d, and the docking bracket 301d transmits the torsional force to the rotating box 301b. After the rotating box 301b rotates, the receiving surface 302k contacts the slope surface 302c, thereby driving the bracket 302i to enter the embedded groove. At this time, the bracket 302i bends so that the structure on the rotating box 301b cannot borrow force. At this time, the filter cartridge 202 idles to achieve the effect of filtering gray water.

[0055] In summary, the setting of the trigger component 302 facilitates better control of the activation of the filtering mechanism 200. When the motor 201 in the device rotates forward, the trigger component 302 is activated, thereby driving the vibration mechanism 300 to work and achieve the vibration effect. The setting of the bracket 302i and the bottom block 302j can effectively control the rotation of the rotating box 301b, and the rotating box 301b is made of stainless steel.
