Description

A drainage device for ash storage Technical Field

[0001] This invention relates to the technical field of power plant ash silos, and in particular to a drainage device for ash silos. Background Technology

[0002] The drainage system of ash silos in thermal power plants is an important component to ensure the safe operation of ash silos. It is responsible for timely drainage of water accumulated in the ash silos to prevent safety problems caused by excessively high water levels.

[0003] The design of an ash silo drainage system needs to consider various factors, such as the silo's volume and specifications, its main structure (concrete or steel), top equipment, level indicator equipment, gasification system, and unloading system. Ash discharge outlets, including dry and wet ash discharge outlets, are typically installed at the bottom of the silo. Unloading and transportation of ash are achieved using appropriate equipment such as dry ash bulk loaders and twin-shaft mixing and humidifying machines. In some cases, to improve the safety of the ash silo drainage system, technical improvements can be implemented. These include increasing the connection between drainage culverts and drainage shafts, and installing concrete plugs within the drainage culverts to enhance the system's stability and safety, ensure unobstructed drainage, and reduce dust pollution and ash water leakage.

[0004] Existing ash sludge discharges along with coal ash, requiring a corresponding drainage and filtration device. During use, the drainage device experiences peak drainage periods and low drainage periods. Existing drainage and filtration devices cannot adjust their filtration effect according to the drainage volume. Therefore, we designed an ash silo drainage device. Summary of the Invention

Detailed Implementation

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, referring to Figures 1 to 3, is the first embodiment of the present invention. This embodiment provides an ash silo drainage device, including a receiving mechanism 100, a filter mechanism 200 disposed in the receiving mechanism 100, and a vibration mechanism 300 disposed on the filter mechanism 200. The receiving mechanism 100 includes a receiving box 101, a water inlet trough 102 and a side plate 103 disposed on the receiving box 101. The vibration mechanism 300 includes a movable component 301 disposed in the filter mechanism 200, and a trigger component 302 disposed between the receiving box 101 and the movable component 301.

[0034] Specifically, the housing mechanism 100 is designed to better protect its internal components and prevent external ash water from contacting the motor 201. The housing mechanism 100 has a rectangular cross-section. The filter mechanism 200 is designed to better filter the water in the ash silo, achieving the effect of separating water from coal slag. The vibration mechanism 300 is designed to better drive the filter mechanism 200 to vibrate, achieving the effect of shaking off coal powder from the filter mechanism 200. The movable component 301 and the trigger component 302 are designed so that the vibration mechanism 300 is activated when the motor 201 rotates forward and is disabled when it rotates backward. The rotation direction of the motor 201 can be selected according to the change of the received water flow. For a period of time after the ash silo is watered, the water flow received by the device increases and then gradually decreases until the next watering operation.

[0035] The filtration mechanism 200 includes a motor 201 disposed inside the housing 101, a filter cylinder 202 disposed at the drive end of the motor 201, and a circular plate 203 and a mounting plate 204 disposed at both ends of the filter cylinder 202. A pusher arc 205 is provided between the circular plate 203 and the mounting plate 204. The drive end of the motor 201 is fixedly connected to the filter cylinder 202 through the circular plate 203. The inner wall of the pusher arc 205 is in contact with the inner wall of the filter cylinder 202. There are multiple pusher arcs 205, which are distributed in a ring array around the filter cylinder 202.

[0036] Furthermore, 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 source. The motor 201 is an existing device and will not be described in detail here. The filter cylinder 202 has a circular cross-section and is fixedly connected to the circular plate 203. The circular plate 203 is fixedly connected to the pusher arc strip 205. The pusher arc strip 205 is made of stainless steel. The pusher arc strip 205 can effectively guide the coal powder located at the top of the filter cylinder 202 away from the device, preventing the coal powder from accumulating on the top of the filter cylinder 202 and damaging its operation.

[0037] In summary, the arrangement of the containing mechanism 100 can better prevent external ash water from contacting the motor 201. The cross-section of the pusher arc 205 is circular, and the arrangement of multiple pusher arcs 205 in a ring shape can effectively guide the coal powder located at the top of the filter cylinder 202 away from the device, preventing coal powder from accumulating on the top of the filter cylinder 202 and damaging its operation. The inner wall of the water inlet trough 102 is provided with a rubber pad to increase the sealing between the pusher arc 205 and the water inlet trough 102. The side of the containing box 101 is provided with a drainage trough.

[0038] Example 2, referring to Figures 2-5, is the second embodiment of the present invention. Unlike the previous embodiment, the movable component 301 includes a through hole 301a disposed in the middle of the mounting plate 204, a rotating box 301b disposed in the through hole 301a, and an external connection hole 301c disposed in the rotating box 301b. A docking frame 301d and an external support 301e are provided on the outside of the rotating box 301b. An internal hole 301f is provided between the docking frame 301d and the external support 301e. The internal hole 301f located inside the docking frame 301d is fixedly connected to a limit rod 301g and a return spring 301h respectively. The other end of the return spring 301h is fixedly connected to the docking frame 301d.

[0039] In another specific embodiment, the active component 301 includes a through hole 301a disposed in the middle of the mounting plate 204, a rotating box 301b disposed in the through hole 301a, an external connection hole 301c disposed in the rotating box 301b, a docking frame 301d and an external support 301e disposed outside the rotating box 301b, an internal hole 301f disposed between the docking frame 301d and the external support 301e, the internal hole 301f located inside the docking frame 301d is fixedly connected to a limit rod 301g and a return spring 301h respectively, the other end of the return spring 301h is fixedly connected to the external support 301e, the other end of the limit rod 301g is slidably installed in the internal hole 301f inside the external support 301e, and the return spring 301h is sleeved on the limit rod 301g.

[0040] Specifically, the cross-section of the docking frame 301d is T-shaped, which effectively connects the trigger assembly 302 to the external structure. The cross-section of the through hole 301a is circular, and the center point of the through hole 301a is the same as that of the mounting plate 204. The cross-section of the rotating box 301b is circular, the cross-section of the external hole 301c is circular, and there is a gap between the docking frame 301d and the external bracket 301e. The cross-section of the internal hole 301f is circular, and the internal hole 301f facilitates the addition of [something] between the docking frame 301d and the external bracket 301e. The component is designed to control the distance and relative position between the docking frame 301d and the external support 301e. The limiting rod 301g is made of stainless steel. The setting of the limiting rod 301g facilitates better limiting of the external support 301e. The return spring 301h can effectively control the distance between the external support 301e and the docking frame 301d. When the external support 301e moves towards the docking frame 301d, the return spring 301h contracts and accumulates elastic potential energy. When the external force is removed, it can effectively drive the external support 301e to return to its original position.

[0041] The through hole 301a is rotatably connected to the rotating box 301b, and the cross-sections of both the rotating box 301b and the through hole 301a are circular.

[0042] In another specific embodiment, the outer wall of the docking frame 301d is in contact with the inner wall of the return spring 301h.

[0043] Furthermore, the cross-section of the rotating box 301b is annular, and the through hole 301a can effectively limit the rotation box 301b. The docking frame 301d is fixedly connected to the rotating box 301b.

[0044] The active component 301 also includes a roller 301i disposed on the external bracket 301e, a base 301j disposed between the mounting plate 204 and the roller 301i, and an abutting worm gear 301k disposed between the abutting worm gear 301k and the base 301j. A guide plate 301l is provided between the abutting worm gear 301k and the base 301j.

[0045] Preferably, the outer wall of the roller 301i and the base 301j can effectively support the external bracket 301e. The abutting worm gear 301k allows the external bracket 301e to move towards the docking frame 301d under the limiting action of the roller 301i during its movement. The abutting worm gear 301k is fixedly connected to the mounting plate 204 and the guide plate 301l. The guide plate 301l can effectively guide the roller 301i located at the base 301j to the abutting worm gear 301k. The roller 301i is rotatably connected to the external bracket 301e through a bearing. The guide plate 301l is in contact with the base 301j, and the inner wall of the guide plate 301l is in contact with the bottom outer wall of the roller 301i. The outer wall of the base 301j is arc-shaped and fits against the roller 301i.

[0046] The rest of the structure is the same as in Example 1.

[0047] During use, water is sprayed in the ash silo to prevent dust from overflowing. The water spraying is generally saturated. After the ash silo is sprayed, the ash water will accumulate in the water storage area of ​​the ash silo for a period of time. When there is a lot of water in the water storage area, it needs to be drained. When the water spraying starts, the motor 201 rotates forward, driving the moving component 301 and the trigger component 302 to run. When the motor 201 rotates forward, the vibration mechanism 300 is started. The vibration mechanism 300 drives the filter cylinder 202 to vibrate, which can effectively filter the ash water and prevent impurities remaining on the filter cylinder 202 from affecting the filtration effect.

[0048] When the watering ends, the water storage area is in a seeping state with less water, so rapid filtration is not required. In order to save energy, the motor 201 is reversed. When the motor 201 reverses, the vibration mechanism 300 is disabled. The motor 201 drives the filter cylinder 202 to run idle, which can perform simple filtration of the gray water.

[0049] In summary, the setting of the limiting rod 301g facilitates better limiting of the external bracket 301e, the return spring 301h can effectively control the distance between the external bracket 301e and the docking frame 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 abutting worm gear 301k can allow the external bracket 301e to move towards the docking frame 301d under the limiting action of the roller 301i during the movement.

[0050] Example 3, referring to Figures 1-7, is the third embodiment of the present invention. The difference from the previous embodiment is the trigger component 302. The trigger component 302 includes a rotating block 302a disposed in the external connection hole 301c. The rotating block 302a is fixedly connected to the housing 101. A side block 302b is disposed on the rotating block 302a. The side block 302b has a slope surface 302c and a stopping surface 302d on both sides respectively.

[0051] Specifically, the trigger component 302 is designed to better control 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 and achieve the effect of vibration, which vibrates the filter cylinder 202 to achieve the effect of shaking the material and preventing material blockage. When the reverse rotation occurs, the trigger component 302 is not activated, thereby causing the vibration mechanism 300 to fail. At this time, the power consumption of the motor 201 decreases, which is conducive to saving energy. The rotation direction of the motor 201 can be selected according to the changes in the received water flow.

[0052] The triggering component 302 also includes an external rotating rod 302e and an internal rotating rod 302f rotatably disposed in the rotating box 301b, and a top strip 302g and a side strip 302h fixedly disposed in the rotating box 301b. The internal rotating rod 302f is provided with a bracket 302i on its outside. One side of the bracket 302i is arc-shaped. A bottom block 302j is fixedly connected to the bottom of the bracket 302i. The bottom block 302j is provided with a receiving surface 302k and a flat surface 302l on its two sides, respectively. The inner wall of the rotating box 301b is provided with a receiving groove 302m. The outer wall of the internal rotating rod 302f fits against the inner wall of the bracket 302i. Both the external rotating rod 302e and the internal rotating rod 302f are rotatably connected to the rotating box 301b. The receiving surface 302k and the flat surface 302l correspond to the slope surface 302c and the stopping surface 302d, respectively.

[0053] Furthermore, both the external rotating rod 302e and the internal rotating rod 302f consist of a positioning rod and a cylinder rotatably connected to the rod. During operation, when the external components come into contact with the external rotating rod 302e and the internal rotating rod 302f, they will rotate, thereby reducing friction. The top bar 302g has an "L"-shaped cross-section, which effectively abuts against the bracket 302i, thus preventing the bracket 302i from contacting the rotating box 301b and slipping off. The bracket 302i is limited by the top bar 302g and the side bar 302h. Under the action of the position, it can effectively limit the position. The setting of the accommodating groove 302m facilitates better limiting of the bracket 302i and prevents the bracket 302i from slipping during the movement, thereby better limiting the bracket 302i and the bottom block 302j. The receiving surface 302k and the slope surface 302c are both arc surfaces. The slope surface 302c can effectively drive the bottom block 302j to move. The setting of the stopping surface 302d can effectively drive the bottom block 302j and the bracket 302i to move under the limiting action of the plane 302l.

[0054] The rest of the structure is the same as in Example 2.

[0055] During use, the motor 201 rotates, driving the circular plate 203 and filter cartridge 202 to rotate. The rotation of the filter cartridge 202, in turn, drives the mounting plate 204 to rotate. The rotation of the mounting plate 204 causes the base plate, guide plate 301l, and volute frame to rotate. This causes the guide plate 301l to apply pressure to the roller 301i, causing it to rotate. The torsional force of the roller 301i is transmitted to the external bracket 301e and the docking bracket 301d. The torsional force is transmitted to the rotating box 301b. After the rotating box 301b rotates slightly, the stopping surface 302d comes into contact with the plane 302l. After the plane 302l is squeezed, it causes the other end of the bracket 302i to come into contact with the top bar 302g, so that the top bar 302g and the bracket 302i come into contact. At this time, the external rotating rod 302e is limited by the bracket 302i, so that the rotating box 301b stops rotating. The rotating box 301b stops rotating, which causes the docking frame 301d and the external support 301e to stop rotating.

[0056] At this time, the guide plate abuts against the roller 301i, causing the roller 301i to move towards the docking frame 301d. The roller 301i drives the external bracket 301e to compress the return spring 301h. The return spring 301h contracts, thereby accumulating elastic potential energy. When the roller 301i has completely passed the abutting worm gear 301k, the roller 301i is no longer abutted. At this time, the elastic potential energy of the return spring 301h is released, causing the roller 301i to return to its original position. When the roller 301i returns to its original position, it impacts the base 301j. After being impacted, the base 301j causes the filter cartridge 202 to vibrate, thereby shaking out the dust on the filter cartridge 202 and achieving an effective filtration effect.

[0057] When motor 201 reverses, it drives circular plate 203 to rotate. During the rotation of circular plate 203, it drives filter cartridge 202 to rotate. During the rotation of filter cartridge 202, it drives mounting plate 204 to rotate. The rotation of mounting plate 204 drives base plate, guide plate 301l, and vortex frame to rotate. Thus, guide plate 301l applies pressure to roller 301i, causing roller 301i to rotate. The torsional force of roller 301i is transmitted to external bracket 301e and docking bracket 301d. The docking bracket 301d transmits the torsional force to rotating box 301b. After rotating box 301b, the receiving surface 302k contacts the slope surface 302c, thereby driving the hanger 302i into the receiving groove 302m. At this time, the hanger 302i bends, so that the structure on rotating box 301b cannot provide support. At this time, filter cartridge 202 rotates freely to achieve the effect of filtering gray water.

[0058] In summary, the trigger component 302 facilitates better control 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 and achieve the vibration effect. The bracket 302i and the base block 302j can effectively control the rotation of the rotating box 301b, which is made of stainless steel.
