Technical Field

[0001] The utility model belongs to the technical field of crushing devices, and in particular relates to an ash crusher for ash recycling. Background Art

[0002] With the continuous development of the scale of my country's coal, mining, construction and other industries, the types and numbers of crushers are increasing, and the models are becoming more and more diverse. As the quality requirements of various industries for crusher products continue to increase, higher requirements are placed on crusher technology.

[0003] The crushers currently on the market are unable to screen the crushing results, resulting in poor crushing effect, and the feeding method is inconvenient to use, which easily causes the crushed slag to float and cannot be screened out. In response to the above technical problems, the applicant has retrieved some prior art, such as the Chinese patent with patent publication number CN220759531U. When in use, it is possible to automatically feed by setting a first guide cavity, and the crushing is more complete by setting a first crushing shaft and a second crushing shaft. By setting a second guide cavity, it has the effect of reprocessing unqualified products. However, the processing process requires multiple pushing of the ash position, which is cumbersome and will cause ash to remain in the equipment, reducing the efficiency of the crushing process. Utility Model Content

[0004] The utility model aims to provide an ash crusher for ash recycling, aiming to solve the technical problem that the steps of ash crushing in the prior art are complicated and the crushing efficiency is reduced.

[0005] The utility model is realized in this way: an ash crusher for ash recycling comprises a shell, in which two sets of parallel pulverizing shafts are rotatably installed, the two sets of pulverizing shafts are rotatably connected by belts, and a rotating power member for driving the pulverizing shafts to rotate is fixedly installed on the side of the shell;

[0006] A mounting ring is fixedly installed on the side wall where the crushing shaft is installed in the shell, and a rotating ring is rotatably installed on the mounting ring. A filter cartridge is rotatably installed on the two sets of rotating rings, and the filter cartridge and the mounting ring are coaxially arranged and the filter cartridge is rotatably connected to one set of crushing shafts. A plurality of support plates are fixedly installed on the inner wall of the filter cartridge, and feed pipes are provided at both ends of the shell, which are connected to the filter cartridge, and a feed trough is provided on the bottom surface of the shell.

[0007] Further technical solution: the axis of the mounting ring and the symmetry axes of the two groups of crushing shafts are located on the same straight line, and the two groups of crushing shafts are located inside the mounting ring.

[0008] Further technical solution: A plurality of groups of spaced-apart partitions are fixedly mounted on the outer side of the rotating ring, and the partitions are fixedly connected to the filter cartridge.

[0009] Further technical solution: guide rings are fixedly installed at both ends of the filter cartridge, the cross section of the guide ring is triangular, and the inner side of the guide ring is higher at one end close to the side wall of the shell.

[0010] Further technical solution: A coaxially arranged gear ring is fixedly installed on the inner side of the rotating ring, and the gear ring is meshed with a gear fixedly installed on one set of pulverizing shafts.

[0011] Further technical solution: the support plates are distributed in a circular array around the axis of the filter cartridge, and an angle is set between the support plates and the radial direction of the filter cartridge.

[0012] Further technical solution: a baffle is fixedly installed in the shell, the baffle is located in the rotating ring and is in sliding contact with the inner wall of the rotating ring, and a through hole is opened on the baffle for the crushing shaft to pass through.

[0013] Further technical solution: the two groups of baffles are jointly fixed with a first guide plate, the two groups of crushing shafts are located at the blanking end of the first guide plate, the first guide plate is provided with an angle with the horizontal plane, two groups of symmetrically distributed second guide plates are fixedly installed on the upper surface of the first guide plate, the second guide plates are provided with an angle with the length direction of the first guide plate and the ends of the two groups of second guide plates close to each other are located at the lower end of the first guide plate, and multiple groups of through grooves are provided on the second guide plate.

[0014] Further technical solution: the two groups of baffles are commonly fixedly mounted with a third guide plate, the third guide plate is set at an angle with the horizontal plane, and the first guide plate is located at the blanking end of the third guide plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. When the support plate rotates to tilt below the horizontal plane, the ash on the support plate can move downward under the action of gravity and fall between the two sets of crushing shafts. The ash can then be crushed by the crushing shafts. The crushed ash falls onto the filter cartridge. Ash that meets the standard particle size will pass through the filter cartridge downward and leave the shell through the drop chute. Ash that does not meet the standard will be driven by the support plate to move to the top of the crushing shaft for crushing again, thereby achieving continuous cycle crushing of the ash, improving the speed and efficiency of ash crushing, and realizing real-time filtration of the ash. The filter cartridge remains in a rotating state to avoid ash clogging the filter cartridge, thereby improving the efficiency of ash crushing.

[0017] 2. When the ash falls from the support plate, it will fall on the first guide plate and the second guide plate. Since the first guide plate and the second guide plate are both inclined, the ash on the second guide plate will slide onto the first guide plate, and then the ash will slide down along the first guide plate. During the downward sliding process, the ash will contact the second guide plate. Part of the ash will slide directly downward through the through groove, and part of the ash will continue to move downward along the second guide plate and slide down from the through groove on the rear side, so that the ash gathered at both ends can be dispersed and moved to the middle, so that the ash can be evenly distributed, thereby improving the subsequent ash crushing and filtering effects.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] like Figure 1-Figure 5 As shown, an ash crusher for ash recycling provided by the utility model comprises a shell 1, in which two sets of parallel pulverizing shafts 2 are rotatably installed, and the surfaces of the pulverizing shafts 2 are provided with pulverizing cones, and the two sets of pulverizing shafts 2 are rotatably connected by a belt 4, and a rotating power part 3 for driving the pulverizing shafts 2 to rotate is fixedly installed on the side of the shell 1;

[0027] A mounting ring 5 is fixedly mounted on the side wall where the crushing shaft 2 is mounted in the housing 1, and a rotating ring 6 is rotatably mounted on the mounting ring 5. The axis of the mounting ring 5 and the symmetric axis of the two groups of crushing shafts 2 are located on the same straight line. The two groups of crushing shafts 2 are located in the mounting ring 5, and the two groups of rotating rings 6 are rotatably mounted with a filter cartridge 9. A plurality of groups of spaced partitions 7 are fixedly mounted on the outer side of the rotating ring 6, and the partitions 7 are fixedly connected to the filter cartridge 9. Guide rings 8 are fixedly mounted on both ends of the filter cartridge 9. The cross section of the guide ring 8 is triangular, and the inner side of the guide ring 8 is close to the end of the side wall of the housing 1. The degree is relatively high, the filter cartridge 9 is coaxially arranged with the mounting ring 5 and the filter cartridge 9 is rotatably connected with one set of the crushing shafts 2, a coaxially arranged gear ring 11 is fixedly installed on the inner side of the rotating ring 6, the gear ring 11 is meshed with a gear 10 fixedly installed on one set of the crushing shafts 2, a plurality of groups of support plates 18 are fixedly installed on the inner wall of the filter cartridge 9, the support plates 18 are distributed in a circular array around the axis of the filter cartridge 9, an angle is set between the support plates 18 and the radial direction of the filter cartridge 9, feed pipes 17 are set at both ends of the shell 1, the feed pipes 17 are connected with the filter cartridge 9, and a drop chute 19 is opened on the bottom surface of the shell 1.

[0028] In actual application of this embodiment, the ash is introduced into the housing 1 from the feed pipes 17 at both ends, and the two groups of crushing shafts 2 are driven to rotate simultaneously by the rotating power member 3. The ash falls from the gap between the filter cartridge 9 and the rotating ring 6 to the area between the partition plates 7 on the rotating ring 6. Part of the ash directly enters the filter cartridge 9. When the crushing shaft 2 rotates, the rotating ring 6 and the filter cartridge 9 are driven to rotate synchronously. When the ash rotates to the bottom of the crushing shaft 2, the ash contacts the inner side of the guide ring 8 under the action of gravity. Since the inner side of the guide ring 8 is an inclined structure, the ash leaves the mounting ring 5 and moves to the area where the support plate 18 in the filter cartridge 9 is located.

[0029] Afterwards, when the filter cartridge 9 rotates, the support plate 18 drives the ash at the bottom of the filter cartridge 9 to move. When the support plate 18 rotates to tilt below the horizontal plane, the ash on the support plate 18 can move downward under the action of gravity and fall between the two sets of crushing shafts 2. The ash can then be crushed by the crushing shafts 2, and the crushed ash falls onto the filter cartridge 9. Ash that meets the standard particle size will pass through the filter cartridge 9 downward and leave the shell 1 through the drop chute 19. Ash that does not meet the standard will be driven by the support plate 18 to move to the top of the crushing shaft 2 for crushing again, thereby realizing continuous circulation crushing of ash, improving the speed and efficiency of ash crushing, and realizing real-time filtration of ash. The filter cartridge 9 remains in a rotating state to avoid ash clogging the filter cartridge 9, thereby improving the efficiency of ash crushing.

[0030] In an example of this embodiment, the rotating power component 3 is a motor, and of course it can also be other components that can output rotating power, such as a hydraulic motor, etc. The motor drives the crushing shaft 2 to rotate to crush the ash.

[0031] like Figure 3-Figure 5 As shown, an ash crusher for ash recycling provided by the utility model is provided. A baffle 12 is fixedly installed in the shell 1. The baffle 12 is located in the rotating ring 6 and is in sliding contact with the inner wall of the rotating ring 6. A through hole is opened on the baffle 12 for the crushing shaft 2 to pass through.

[0032] Specifically, the two groups of baffles 12 are jointly fixedly installed with a first guide plate 13, the two groups of crushing shafts 2 are located at the blanking end of the first guide plate 13, the first guide plate 13 is set with an angle with the horizontal plane, and two groups of symmetrically distributed second guide plates 14 are fixedly installed on the upper surface of the first guide plate 13, the second guide plates 14 are set with an angle with the length direction of the first guide plate 13, and the ends of the two groups of second guide plates 14 close to each other are located at the lower end of the first guide plate 13, and multiple groups of through grooves 15 are opened on the second guide plate 14.

[0033] Specifically, the two groups of baffles 12 are commonly fixed with a third guide plate 16 , the third guide plate 16 is set with an angle with the horizontal plane, and the first guide plate 13 is located at the blanking end of the third guide plate 16 .

[0034] When this embodiment is actually used, the ash will fall onto the first guide plate 13 and the third guide plate 16 when falling from the support plate 18. Since the first guide plate 13 and the third guide plate 16 are both inclined, the ash on the third guide plate 16 will slide onto the first guide plate 13, and then the ash will slide downward along the first guide plate 13. During the downward sliding process, the ash will contact the second guide plate 14. Part of the ash will slide directly downward through the through groove 15, and part of the ash will continue to move downward along the second guide plate 14 and slide downward from the through groove 15 on the rear side, so that the ash gathered at both ends can be dispersed and moved to the middle, so that the ash can be evenly distributed, thereby improving the subsequent ash crushing and filtering effects.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
