Description

Technical Field

[0001] The utility model relates to the technical field of ash recovery and treatment, in particular to boiler ash cleaning equipment. Background Art

[0002] Boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. Boiler ash refers to the final product formed after the minerals in the coal are burned in the furnace under the high temperature and undergo certain physical and chemical changes. Since ash in the boiler will cause contamination, slagging, corrosion and wear of the heating surface, affecting the normal operation of the boiler, it is necessary to remove the ash effectively and promptly.

[0003] Part of the ash is discharged from the slag hopper behind the grate of the layer-fired furnace, the cold ash hopper at the bottom of the furnace of the pulverized coal furnace, or the slag outlet and slag well at the bottom of the liquid slag discharge furnace, which is called slag discharge. The slag needs to be transported to the slag field using the boiler slag discharge device, which is called slag discharge. The timely transportation and treatment of high-temperature slag is a necessary link for the safe operation of the boiler.

[0004] After the boiler ash is cleaned out from the inside of the boiler, it can be processed and reused. For example, after magnetic separation and gravity separation to separate scrap steel and other metals, it can be used as a paving pad, a landfill cover material, and a material for making unburned bricks, which greatly improves resource utilization. It is known that in the subsequent treatment of ash, crushing equipment is usually required to crush the ash.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-6 , the present utility model provides a technical solution: a boiler ash cleaning device, including a frame 1 and a crushing box 2 installed on the frame 1. Inside the crushing box 2, there is a crushing member 8 for crushing ash, and a sieve plate 5 is also arranged inside the crushing box 2. The sieve plate 5 is located below the crushing member 8. A striking assembly 6 is also arranged on the crushing box 2. A driving member for driving the striking assembly 6 to rotate is arranged on the crushing box 2. While the driving member drives the crushing member 8 to move, it drives the crushing member 8 to rotate through a first synchronizing member 9 for crushing operations.

[0030] Specifically, the boiler ash cleaning device includes a frame 1 and a crushing box 2 installed on the frame 1. Specifically, a supporting member is arranged at the bottom of the frame 1, and an anti-slip pad is arranged at the bottom of the supporting member, thereby improving the stability of the entire cleaning device during use and meeting the working requirements. Specifically, a crushing member 8 for crushing ash is arranged inside the crushing box 2, greatly improving the practicability of the cleaning device. And a sieve plate 5 is also arranged inside the crushing box 2. The sieve plate 5 is located below the crushing member 8. The crushed ash is screened through the sieve plate 5, thereby greatly improving the practicability of the cleaning device. A striking assembly 6 is arranged on the crushing box 2 to prevent the sieve plate 5 from being blocked and affecting the screening efficiency. A driving member for driving the striking assembly 6 to rotate is arranged on the crushing box 2 to meet the working requirements. While the driving member drives the crushing member 8 to move, it drives the crushing member 8 to rotate through a first synchronizing member 9 for crushing operations. Therefore, during use, when the driving member drives the striking assembly 6 to intermittently strike the sieve plate 5, the crushing member 8 is driven to rotate on the crushing box 2 through the first synchronizing member 9 to perform crushing operations on the ash. The crushed ash will then pass through the sieve plate 5 for screening. At the same time, the striking assembly 6 intermittently strikes the sieve plate 5 to prevent the sieve plate 5 from being blocked. This cycle is repeated, greatly improving the practicability of the ash cleaning device and being suitable for wide promotion and use.

[0031] In the embodiment provided by the present utility model, the striking assembly 6 includes a driving rod 6.2 rotatably connected to the crushing box 2. A striking ring 6.1 is installed on the driving rod 6.2. The striking ring 6.1 intermittently strikes the sieve plate 5. The driving member is a servo motor 12. The driving shaft of the servo motor 12 is coaxially connected to the driving rod 6.2. Specifically, the servo motor 12 is equipped with a reducer by itself to meet the working requirements. When the driving rod 6.2 rotates, the striking ring 6.1 intermittently strikes the sieve plate 5 to meet the working requirements.

[0032] In the embodiment provided by the present utility model, the crushing member 8 includes two power rods 8.3 rotatably connected to the crushing box 2. A gear 8.2 is installed on each power rod 8.3. The two gears 8.2 are meshed. And a crushing knife 8.1 is installed on each power rod 8.3 for crushing ash slag. The first synchronizing member is installed on the driving rod 6.2 and one of the power rods 8.3. When the driving force rotates, the two crushing knives 8.1 are driven to rotate towards each other through the meshing of the two gears 8.2 to perform the crushing operation on the ash slag.

[0033] In the embodiment provided by the present utility model, the sieve plate 5 is in an inclined state. And a waste collection component is further provided on the crushing box 2. The waste collection component includes a discharge channel 7 installed on the crushing box 2. And a discharge port is opened on the crushing box 2. The waste is discharged through the discharge channel 7. And a material collection box 14 body for collecting waste is further provided on the frame 1. Therefore, during the use process, the ash slag particles that cannot pass through the sieve plate 5 with a large size will be discharged through the discharge channel 7 and fall into the material collection box 14 body, which is convenient for the secondary crushing operation.

[0034] In the embodiment provided by the present utility model, crushing plates 13 are further provided on both sides of the crushing box 2. The crushing plates 13 are respectively adapted to the crushing knives 8.1 to perform the crushing operation better.

Specifically, the working principles of the first synchronizing member 9 and the second synchronizing member 10 are the same. Therefore, by providing the first conveyor 3, it is convenient to transfer the crushed ash slag to a predetermined area. Therefore, during the use process, while the servo motor 12 realizes the crushing operation and the striking operation, it can also realize the output operation of the crushed waste, further improving the practicability of the cleaning device.

[0036] In the embodiment provided by the present utility model, a second conveying member 4 is arranged on the frame 1. The second conveying member 4 includes a plurality of second transmission rods 4.1 rotatably connected to the frame 1. A second transmission belt is sleeved between the plurality of second transmission rods 4.1. The second transmission belt is in an inclined state and feeds materials to the crushing box 2.

The structures and working principles of the first synchronizing member 9, the second synchronizing member 10 and the third synchronizing member 11 are the same and meet the working requirements. By arranging the second conveying member 4, it is convenient to feed materials into the box body and the use effect is better. Therefore, during the use process, while the servo motor 12 realizes the crushing operation, the striking operation and the output operation, it can also realize the feeding operation, making full use of the power of the servo motor 12. Specifically, both the first conveying member 3 and the second conveying member 4 are prior arts.
