Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coal mine filling equipment manufacturing, especially to a building type crushing filling system. BACKGROUND

[0002] Coal gangue is a solid waste discharged in the process of coal mining and coal washing, and is a black gray rock with low carbon content and higher hardness than coal, which is associated with coal seams in the process of coal formation. From the perspective of coal mining, China discharges about 14 million tons of gangue for every 100 million tons of coal produced; from the perspective of coal washing and processing, it discharges 20 million tons of gangue for every 100 million tons of coking coal washed and processed, and 15 million tons of gangue for every 100 million tons of power coal washed and processed. There are more than 1,500 gangue dumps in state-owned coal mines across the country, with a cumulative volume of more than 3 billion tons, accounting for more than 40% of the total amount of industrial solid waste discharged in China. The large-scale stacking of coal gangue not only occupies land and affects the ecological environment, but also pollutes the surrounding soil and groundwater through gangue leaching water. In addition, coal gangue contains certain combustible materials, which can cause spontaneous combustion under suitable conditions, emitting harmful gases such as sulfur dioxide, nitrogen oxides, carbon oxides, and smoke dust, polluting the atmospheric environment and affecting the health of residents in the mining area.

[0003] As a solid waste of mining industry, coal mining activities leave a large number of goaf areas. If not treated in time, the size of the goaf area will become larger and larger, which can cause the sudden collapse of the roof rock layer of the goaf area, not only endangering the safety of the operation, but also causing the movement and deformation of the overburden layer and even the surface layer, and in severe cases, it can lead to major geological disasters such as surface subsidence and ground fissures, causing serious damage to surface buildings. In addition, the large-scale stacking of coal gangue not only occupies land and affects the ecological environment, but also pollutes the surrounding soil and groundwater through gangue leaching water. In addition, coal gangue contains certain combustible materials, which can cause spontaneous combustion under suitable conditions, emitting harmful gases such as sulfur dioxide, nitrogen oxides, carbon oxides, and smoke dust, polluting the atmospheric environment and affecting the health of residents in the mining area.

[0004] With the rapid development of the times, the problem of ground subsidence caused by abandoned coal mines is serious. Therefore, a large amount of coal gangue is needed to fill the subsidence area to prevent ground subsidence and improve the coal mining rate. The existing coal gangue filling method is used to realize coal gangue separation. After the coal gangue is crushed to a certain particle size, it is mixed and stirred with mixed additives (such as water, fly ash, cement, etc.), and then transported to the goaf or caving area. The existing coal gangue crushing device is generally constructed using a flat ground infrastructure, which occupies a large area of ground and has high construction and maintenance costs. In addition, how to more economically and efficiently fill the crushed coal gangue into the goaf is one of the problems that existing technical personnel urgently need to solve.

DETAILED DESCRIPTION

[0032] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0033] It should be understood that various modifications can be made to the embodiments described herein. Therefore, the above description should not be construed as limiting, but merely as an example. Those skilled in the art will contemplate other modifications within the scope and spirit of the present application.

[0034] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the application and, together with the general description of the application given above, and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0035] These and other characteristics of the present application will become apparent from the following description of the preferred forms given, by way of non-limiting example, with reference to the attached drawings.

[0036] It is also to be understood that even though numerous specific details of the present application are set out in the following description and are shown in the accompanying drawings, many changes and modifications in the specifics thereof can be made in accordance with the claims that follow, without departing from the spirit and scope of the application.

[0037] The above and other aspects, features, and advantages of the present application will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate by way of non-limiting examples various embodiments of the present application.

[0038] Specific embodiments of the present application are described in detail below with reference to the attached drawings; however, it is to be understood that the application is not limited to the embodiments described, but instead, can be practiced with modifications and alterations all within the scope and spirit of the application. Accordingly, the application is not to be limited as by the detailed description of specific embodiments.

[0039] The specification can use phrases such as "in one embodiment," "in another embodiment," "in yet another embodiment," or "in at least one embodiment" which can refer to one or more embodiments of the application.

[0040] As shown in the drawings, the first embodiment of the present application provides a building type crushing and filling system for crushing coal gangue, tailings and construction waste and other materials into a particle size suitable for filling goaf and filling, wherein the building type structure adopted by the building type crushing and filling system includes but is not limited to a steel structure tower and a concrete building. Figure 1 The building type crushing and filling system includes a crushing building, a finished product warehouse building 300 and a filling device. The building type crushing and filling system further includes a conveying device for conveying materials. In different conveying stages of the materials, the conveying device can be in various forms, for example, a lifting device, a conveyor belt, a screw conveying device, a chute ladder and other devices for conveying materials in the prior art can be used as the conveying device in the present embodiment.

[0041] The building type crushing and filling system includes a crushing building, a finished product warehouse building 300 and a filling device. The building type crushing and filling system further includes a conveying device for conveying materials. In different conveying stages of the materials, the conveying device can be in various forms, for example, a lifting device, a conveyor belt, a screw conveying device, a chute ladder and other devices for conveying materials in the prior art can be used as the conveying device in the present embodiment.

[0042] In the embodiment, the conveyor belt is preferably used for the horizontal or approximately horizontal material transportation, such as the material transportation between different floors, because the conveyor belt is more reliable, easy to maintain and low in cost; the lifting device is preferably used for the vertical or approximately vertical material transportation, such as the material transportation between different floors, because the lifting device can vertically and continuously transport the material and save the size of the planar space. The lifting device can be an elevator, a bucket elevator, a screw conveyor, etc. The elevator is preferably used as the lifting device in the embodiment because the elevator can effectively save the size of the planar space. The device for the material transportation is collectively referred to as a conveying device in the embodiment. In addition, a combination of various conveying devices can be used in the process of conveying the material, such as the combination of the lifting device and the conveyor belt for conveying the material.

[0043] The crushing floor is arranged to crush the material and convey the material crushed to a predetermined particle size to the finished product warehouse floor 300. The crushing floor can realize multi-stage crushing. In the embodiment, the crushing floor can be multiple, such as the crushing floor including a primary crushing floor 100 and a finished product crushing floor 200.

[0044] The primary crushing floor 100 is arranged with a crushing device 400. The crushing device 400 is used to crush the material, such as being arranged to crush the large particle size material to the medium particle size material or the small particle size material, so that the crushed material is suitable for filling the goaf. The crushing device 400 can adopt a jaw crusher, a gyratory crusher, a cone crusher, a roller crusher, a hammer crusher and an impact crusher, etc. The impact crusher is preferably adopted because the impact crusher can crush a large amount of material and directly crush part of the material to the target particle size or close to the target particle size, thereby reducing the work pressure of the next stage of crushing.

[0045] In the process of crushing the material, it is difficult for the crushing device 400 to crush all the material to the required particle size at one time. Therefore, the primary crushing floor 100 in the embodiment can be further arranged with a particle screening device 500.

[0046] Specifically, the particle screening device 500 is arranged to screen the crushed material and deliver the crushed material according to the particle size of the crushed material, for example, deliver the crushed material to the corresponding crushing device 400 in the next stage or the product tank 600 in the product warehouse 300. More specifically, if the crushed material has met the requirements for filling the goaf, the crushed material is directly delivered to the product tank 600; if the particle size of the crushed material changes little, the crushed material is delivered back to the crushing device 400 in the primary crushing warehouse 100; if the particle size of the crushed material changes significantly, the crushed material is delivered to the crushing device 400 in the crushing warehouse in the next stage (for example, the re-crushing warehouse or the product crushing warehouse 200). The embodiment does not limit the specific size of the particle size of the crushed material, and a person of ordinary skill in the art can design and select according to the actual situation.

[0047] It should be noted that, for the material with soft properties, the primary crushing warehouse 100 can also not be provided with the particle screening device 500 since it does not affect the subsequent filling; or the particle screening device arranged at other positions can also be used for screening.

[0048] The particle screening device 500 can adopt an air flow screen, a cylindrical screen, a single-stage vibrating screen, a multi-stage vibrating screen, a roller screen, etc. Preferably, the particle screening device 500 is a multi-stage vibrating screen, and the working principle of the multi-stage vibrating screen is that the screen meshes of different specifications are arranged from top to bottom, and the pore size decreases successively. By using the multi-stage vibrating screen, the screening of materials with multiple particle sizes can be realized, thereby preparing for the delivery of the material to the corresponding device. Compared with other screening devices, the multi-stage vibrating screen can also improve the screening efficiency and reduce the occupied area under the same size.

[0049] Preferably, in the primary crushing warehouse 100, the particle screening device 500 is located above the crushing device 400, so that the large-particle-level material screened by the particle screening device 500 enters the crushing device 400 by gravity, and the delivery of the material can be realized without additionally arranging a delivery device.

[0050] The material is delivered from the stockpile 101 to the feeding bin 120 of the primary crushing warehouse 100, and then falls on the delivery device (for example, a conveyor belt 810 in this embodiment) to be delivered to the crushing device 400.

[0051] In order to make the material be discharged uniformly, the feeding bin 120 of the primary crushing warehouse 100, the feeding bin (not shown in the figure) of the product crushing warehouse 200 and / or the feeding bin (not shown in the figure) of the product warehouse 300 are provided with auxiliary feeding devices, for example, a vibrating feeder, a belt feeder, a magnet, etc. Preferably, the vibrating feeder 110 is used for discharging, and the reason is that the vibrating feeder can make the material be fed more uniformly.

[0052] The finished product crushing tower 200 is provided with another crushing device 400, and the crushing device in the primary crushing tower 100 and the crushing device 400 in the finished product crushing tower 200 can realize multi-stage crushing. The crushing device 400 is used for crushing materials, for example, it can be arranged to crush the medium particle size material formed after the first crushing to small particle size material, so that the crushed material is suitable for filling the goaf. It should be noted that the feeding bin of the finished product crushing tower 200 does not directly receive the material from the stockpile 101, but receives the material crushed by the crushing device 400 in the upper crushing tower (such as the re-crushing tower or the primary crushing tower 100).

[0053] Similar to the primary crushing tower 100, the finished product crushing tower 200 can also be selectively provided with a particle screening device 500. The particle screening device 500 of the finished product crushing tower 200 is arranged to screen the material crushed by the crushing device 400 of the finished product crushing tower 200 and the like, and convey the crushed material according to the particle size of the crushed material, for example, convey the crushed material to the crushing device 400 of the finished product crushing tower 200 or the finished product tank 600 of the finished product bin tower 300; or when the primary crushing tower 100 is not provided with a particle screening device 500, the material crushed by the primary crushing tower 100 can also enter the particle screening device 500 in the finished product crushing tower 200 for screening, at this time, the particle screening device 500 can convey the crushed material to the crushing device 400 of the primary crushing tower 100, the crushing device 400 of the finished product crushing tower 200 or the finished product tank 600 of the finished product bin tower 300 according to the particle size of the crushed material.

[0054] Preferably, in the finished product crushing tower 200, the particle screening device 500 is located below the crushing device 400, so that the material crushed by the crushing device 400 enters the particle screening device 500 by gravity, and the conveying of the material can be realized without additional conveying devices.

[0055] It should be noted that the particle size values of the large particle size material, the medium particle size material and the small particle size material are relative values, and the specific particle size of the corresponding particle size can be adjusted according to the actual working condition of each crushing tower. The separation and conveying of the material according to the particle size of the material can refer to the related contents in the prior art, and therefore will not be described here.

[0056] Exemplarily, when the particle screening device 500 performs three-stage screening (i.e. screening large-particle-level material, medium-particle-level material and small-particle-level material), for coal gangue, the particle size of the large-particle-level material is preferably > 40 mm, the particle size of the medium-particle-level material is preferably 3 mm ~ 40 mm, and the particle size of the small-particle-level material is preferably < 3 mm.

[0057] In an embodiment, the primary crushing floor 100 is the uppermost floor and the finished product crushing floor 200 is the lowermost floor in the direction of material conveying. The finished product bin floor 300 is provided with a finished product tank 600 configured to receive the material having the predetermined particle size, and the discharge port of the finished product tank 600 is in communication with the filling device.

[0058] More specifically, the finished product tank 600 is configured to receive the material after being crushed by the crushing device 400 in the upper crushing floor (e.g. the primary crushing floor 100, the re-crushing floor to be described later or the finished product crushing floor 200), i.e. the material suitable for filling the goaf.

[0059] The filling device is configured to mix the material from the finished product tank 600 with the mixing additives (e.g. water, fly ash, cement, etc.) and convey the mixed material to the goaf.

[0060] In order to avoid injecting unsuitable material into the goaf in case of failure, the filling device can also convey the material to an emergency pool (e.g. a delamination zone, etc.).

[0061] The filling device can include at least one of a mixing and stirring device 710 and a pumping device 720. The mixing and stirring device 710 can be a vertical mixing device or a horizontal mixing device (e.g. a single-shaft horizontal stirrer, a double-shaft horizontal stirrer, etc.), and the pumping device 720 can be a plunger pump, a slurry pump, a sludge pump, a centrifugal pump or a vane pump, etc.

[0062] When the filling device is only the mixing and stirring device 710 (not shown in the figure), the mixing and stirring device 710 mixes the material from the finished product tank 600 with the mixing additives (e.g. water, fly ash, cement, etc.), and the mixed material flows to the goaf by gravity. It should be noted that, since the pumping device 720 is not provided, the heights of the finished product tank 600, the mixing and stirring device 710 and the filling area (the goaf) are sequentially lowered, and the material conveying relies on its own gravity. The water, powder and granular material in the mixing and stirring device 710 are uniformly mixed, and the uniformly mixed material has a certain viscosity (concentration). The certain concentration after stirring can ensure that the material does not separate during long-distance flow in the underground. The self-flowing process of the mixed material is a prior art, which will not be described here.

[0063] When the filling device is only the pumping device 720 (not shown in the figure), the pumping device 720 pumps the material from the finished product tank 600 together with the mixed additives to the goaf.

[0064] When the filling device comprises the mixing and stirring device 710 and the pumping device 720 (as shown in the figure), the mixing and stirring device 710 mixes the material from the finished product tank 600 with the mixed additives, and then the pumping device 720 pumps the mixed material to the goaf. Figure 1

[0065] It should be noted that, according to different actual conditions, a secondary crushing floor (not shown in the figure) can also be additionally arranged between the primary crushing floor 100 and the finished product crushing floor 200. Similar to the primary crushing floor 100 and the finished product crushing floor 200, the secondary crushing floor is also provided with a crushing device, and the secondary crushing floor can also be selectively provided with a particle screening device according to needs, for crushing and screening the material multiple times between the primary crushing floor 100 and the finished product crushing floor 200. The working principle is basically the same as that of the primary crushing floor 100 and the finished product crushing floor 200, and thus will not be described here.

[0066] In order to enable the floor-type crushing and filling system to be applicable to a lower temperature environment and realize winter operation, the floor-type crushing and filling system further comprises a heat preservation device (not shown in the figure), which can be a heat preservation layer or a heating pipeline arranged at the periphery of the frame of each floor. In the present application, the heat preservation layer is preferably used as the heat preservation device, which not only has heat preservation function, but also has noise reduction function, and can prevent dust pollution of the environment.

[0067] The working process of the floor-type crushing and filling system will be described below with reference to the accompanying drawings. Figure 1

[0068] The material is conveyed from the stockpile 101 to the feed bin 120 of the primary crushing floor 100, and the material in the feed bin 120 enters the vibrating feeder 110 and is laid on the conveying device (for example, a conveyor belt 810) under the vibration of the vibrating feeder 110. The conveyor belt 810 conveys the material to the crushing device 400 in the primary crushing floor 100, and the crushing device 400 crushes the material of large particle size.

[0069] The crushed material enters the conveying device (for example, a lifting device 820 such as an elevator, etc.) in the lifting device 820, and the material in the lifting device 820 enters the particle screening device 500 (for example, a multi-stage vibrating screen).

[0070] ​​After the multi-stage vibration screen is vibrated, the large-particle-level material enters the crushing device 400 in the primary crushing building 100 for re-crushing by gravity; the small-particle-level material is transported to the lifting device 820 by the conveying belt 810, and the small-particle-level material is transported to the finished product tank 600 in the finished product building 300 by the lifting device 820; the medium-particle-level material is transported to the lifting device 820 in the finished product crushing building 200 by the conveying belt 810, and the medium-particle-level material is transported to the crushing device 400 in the finished product crushing building 200 by the lifting device 820.

[0071] In this way, the material (crushed by the crushing device 400 in the primary crushing building 100) is re-crushed by the crushing device 400 in the finished product crushing building 200, the material crushed by the crushing device 400 in the finished product crushing building 200 enters the particle screening device 500 in the finished product crushing building 200 for screening by gravity, the medium-particle-level material after screening enters the lifting device 820, and the medium-particle-level material is re-raised into the crushing device 400 in the finished product crushing building 200 by the lifting device 820 for repeated crushing, and the small-particle-level material formed by crushing is directly transported into the finished product tank 600 by the conveying belt 810 and the lifting device 820 in the finished product building 300.

[0072] In the above process, the particle size of the material at different stages and the powder output can be adjusted by adjusting the outlet size of the crushing device 400 in different crushing buildings, the screen size of the multi-stage vibration screen, and the like. Preferably, the outlet size of the crushing device 400 in the primary crushing building 100 is larger than the outlet size of the crushing device 400 in the finished product crushing building 200; and the screen size of the particle screening device 500 in the primary crushing building 100 is larger than the screen size of the particle screening device 500 in the finished product crushing building 200.

[0073] In order to reduce dust pollution, the building-type crushing and filling system further comprises a dust removal device 900, which comprises a negative pressure fan, a dust removal pipeline (such as a dust removal pipe) in communication with the negative pressure fan, and a dust removal filter (such as a dust removal filter) arranged at the outlet of the dust removal pipeline. Figure 1The dust removal pipeline is also communicated with the conveying device, the crushing device 400, one or more of the particle screening devices 500, and a filtering system (not shown in the figure) to collect the powder generated in the crushing process under negative pressure. The present application does not limit the position of the dust removal device 900, and preferably, the dust removal device 900 is arranged to convey the inhaled powder into the finished product tank 600, so that the powder is mixed with the material in the finished product tank 600, thereby reducing dust pollution and increasing the filling amount, that is, the finished product tank 600 also serves as a collection tank for collecting the powder. Of course, the present application is not limited thereto, and a collection tank for collecting the powder can also be arranged separately. The present application also does not limit the structure and type of the dust removal device 900, for example, the dust removal device 900 can be an electrostatic precipitator, a bag-type dust collector, a cyclone dust collector, a wet dust collector, a filter cartridge dust collector, etc. In the present application, the dust removal device 900 composed of a negative pressure fan, a dust removal pipeline and a filtering system is preferably used, because it can more effectively achieve the dust removal effect, has a smaller footprint, and the powder can be utilized.

[0074] In order to ensure the quantitative conveying of the material, so that the material is quantitatively fed into the mixing and stirring device 710 and / or the pumping device 720, and the weight of the material at each link is identified, the tower-type crushing and filling system further comprises a weighing device (not shown in the figure), which is preferably arranged at the conveying device and / or the finished product tank 600 to measure the weight of the material on the conveying device and / or in the finished product tank 600. The weighing control during operation can refer to the prior art, which will not be described here.

[0075] It should be noted that the present application does not limit the type and structure of the crusher, the particle screening device 500, the vibrating feeder 110, the conveyor belt 810, the lifting device 820, the dust removal device 900, the weighing device and other devices, and those skilled in the art can select or adapt the devices in the prior art according to the actual situation.

Figure 2 The first deformation example of the tower-type crushing and filling system is described below with reference to the structure schematic view of the first deformation example of the tower-type crushing and filling system of the present application.

[0077] Compared with the above-mentioned embodiment, the first deformation example mainly differs in that the particle screening device is not arranged in the primary crushing tower 100, that is, the particle screening device 500 is only arranged in the finished product crushing tower 200, and the dust removal device 900 is arranged in the primary crushing tower 100.

[0078] At this time, the material is transported from the stockpile 101 to the feed bin 120 of the primary crushing building 100, the material in the feed bin 120 enters the vibrating feeder 110, and is paved on the conveying device under the vibration of the vibrating feeder 110, and the conveying belt 810 transports the material to the crushing device 400 in the primary crushing building 100, and the crushing device 400 crushes the material of the large particle size.

[0079] The crushed material directly enters the crushing device 400 in the finished product crushing building 200 through the conveying device (for example, the lifting device 820 such as a hoist), and the material crushed by the crushing device 400 in the finished product crushing building 200 is transported to the particle screening device 500 of the finished product crushing building 200 through the conveying device (for example, the lifting device 820), and the medium particle size material screened is transported to the crushing device 400 of the finished product crushing building 200 through gravity for repeated crushing, and the small particle size material formed by crushing is transported to the finished product tank 600 through the conveying belt 810.

[0080] It should be noted that in different conveying stages of the material, different forms of conveying devices can be used by those skilled in the art for conveying, and the conveying devices can be arranged in the crushing building or outside the crushing building, and the utility model is not limited thereto.

[0081] In the first variant, the particle screening device 500 of the primary crushing building 100 is omitted, and the material is only screened in the finished product crushing building 200, which simplifies the process flow, reduces the cost, and is convenient for maintenance.

[0082] Figure 3 The second variant of the floor type crushing and filling system is shown in the structural schematic view, and the following will be described in combination with the above embodiment. Figure 3 The second variant of the floor type crushing and filling system is described.

[0083] The second variant is different from the above embodiment mainly in that the particle screening device is not arranged in the primary crushing building 100, that is, the particle screening device 500 is only arranged in the finished product crushing building 200, and that the dust removal device 900 is arranged in the finished product bin building 300, but the dust removal device 900 is not arranged to transport the suctioned powder into the finished product tank 600, but a collection tank for collecting the powder is separately arranged in the finished product bin building 300, that is, the dust removal device 900 is arranged to transport the suctioned powder into the separately arranged collection tank. In addition, in the variant, part of the conveying device (for example, the conveying device for conveying the material between the finished product crushing building and the finished product bin building) is arranged outside the crushing building and the finished product bin building.

[0084] Figure 4The utility model discloses a third deformation example structure diagram of building type crushing filling system. Figure 4 The third deformation example of building type crushing filling system is described.

[0085] The third deformation example compared with the second deformation example, its difference mainly is: material is broken by the crushing device 400 of the primary crushing building 100, is transported to the particle screening device 500 of the finished product crushing building 200 through conveying device and carries out screening.

[0086] Specifically, material is transported from the material pile 101 to the feed bin 120 of the primary crushing building 100, and the material in the feed bin 120 enters the vibrating feeder 110 and is laid on the conveying device under the vibration of the vibrating feeder 110, and the conveying belt 810 transports the material to the crushing device 400 in the primary crushing building 100, which breaks the material of large particle size.

[0087] The broken material directly enters the particle screening device 500 in the finished product crushing building 200 through the conveying device (herein, the combination of the conveying belt 810 and the lifting device 820) for screening, and the material of large particle size enters the crushing device 400 in the primary crushing building 100 for re-breaking after screening; the material of small particle size is transported to the finished product tank 600 of the finished product warehouse building 300; and the material of medium particle size is transported to the crushing device 400 in the finished product crushing building 200 for crushing.

[0088] In other words, in the third deformation example, the particle screening device 500 in the finished product crushing building 200 not only receives the material broken by the crushing device 400 in the finished product crushing building 200, but also receives the material broken by the crushing device 400 in the primary crushing building 100. That is, only one particle screening device 500 can screen the material broken by the primary crushing building 100 and the finished product crushing building 200, which reduces the production cost and improves the efficiency, can more effectively screen the material, and is beneficial to reduce the power consumption.

[0089] As can be seen from the above, the primary crushing building, the finished product crushing building and the finished product warehouse building are designed in the embodiment, so that the layout of each device is more reasonable, and the occupied space is smaller; the multi-stage crushing can further refine the material, realize the integrated full-process continuous operation filling including raw material crushing and filling, and when maintenance and change (increase, decrease or replace the building) are needed, the assembly can be directly carried out in the unit of building, and the influence on other equipment is reduced.

The multilayer frame structure especially adopts building structure of steel structure, which has the advantages of short construction period, small land occupation area and high equipment integration, can effectively implement equipment operation process monitoring, improve automation degree and facilitate maintenance.

[0100] Further, the discharge port of the buffer bin is arranged at the height of the first layer for example, and the feeding port of the buffer bin generally has a predetermined height, which can be the height of the second layer or higher for example. The height of the buffer bin is related to the amount of materials required. The buffer bin can effectively control the feeding amount of the wet mill, so as to adjust the amount of materials for grinding.

[0101] Specifically, the crushed materials are lifted to a predetermined height by the lifting device and conveyed into the feeding port of the buffer bin through the second conveying device, and the materials are discharged from the discharge port of the buffer bin. Further, a third conveying device with a weighing function is arranged between the discharge port of the buffer bin and the feeding port of the wet mill. In this way, the materials crushed by the crushing device are discharged from the buffer bin and ground by the wet mill,

[0102] In this way, the discharge port of the buffer bin is connected with the feeding port of the third conveying device, the third conveying device can be a weighing belt for example, the discharge port of the third conveying device is connected with the feeding port of the wet mill, and the third conveying device is used to measure the volume or weight of the materials while conveying the materials.

[0103] Finally, the weighed materials are ground in the wet mill, and the discharge port of the wet mill is connected with the filling device, so that the crushed and ground materials are mixed and filled into the underground goaf by a pumping device for example.

[0104] In other embodiments, there are multiple crushing devices, and the multiple crushing devices are respectively arranged on different floors of the building. The discharge port of the crushing device on the upper floor is connected to the feed port of the crushing device on the next adjacent floor, and the discharge port of the crushing device on the lowest floor among all the crushing devices is connected to the feed port of the wet grinder through the lifting device and the buffer silo.

[0106] In one specific embodiment, the tower-type crushing and filling system can achieve multi-stage crushing and grinding of materials, thereby achieving finer particle size crushing and shaping than a two-stage crushing system. Other devices, such as the filling device, can refer to the first embodiment described above. A detailed description is provided herein with reference to the accompanying drawings.

[0107] like Figures 5-9 As shown, it includes a multi-layer frame structure 20, a buffer silo 4, and a lifting device 2. The multi-layer frame structure 20 includes a first layer 20a, a second layer 20b, and a third layer 20c, which are arranged in sequence. The first layer 20a is set on the ground, the second layer 20b is located above the first layer 20a, and the third layer 20c is located above the second layer 20b. Here, the multi-layer frame structure 20 is provided with a crushing device on the third layer 200c, the second layer 200b, and the first layer 200a from top to bottom, so that the three crushing devices can achieve multi-stage crushing of the material.

[0108] Specifically, a first multi-tooth roller crusher 1 (equivalent to a first-stage crushing device) is arranged on the third layer 20c of the multi-layer frame structure 20, which is directly connected to the coal gangue raw gangue bin through, for example, a belt conveyor. The first multi-tooth roller crusher 1 here can be flexibly arranged according to the location of the coal gangue raw gangue bin on site, and there is no need to set the position sequence and positioning; a second multi-tooth roller crusher 5 (equivalent to a second-stage crushing device) is arranged on the second layer 20b of the multi-layer frame structure 20; a ball mill 14 (equivalent to a wet grinder), a buffer tank 13 and a pumping device 12 are arranged in sequence on the first layer 20a of the multi-layer frame structure 20.

[0109] Considering that the existing crushing devices generally adopt counterattack breaking, hammer crusher, jaw crusher and other devices, such devices have the defects of large size, large vibration, high frequency of replacement of wearing parts, high energy consumption and relatively uneven crushed materials, which leads to obvious defects in the operation mode of coal gangue filling, mixing and filling. The first and second crushing devices in the embodiment can adopt toothed roll crushers, which have the advantages of small size, small vibration, obvious matching advantages with the steel structure building structure and the filling device, relatively uniform materials after crushing, low energy consumption, convenient maintenance and the like. The first multi-toothed roll crusher 1 is preferably a double-toothed roll crusher, and the second multi-toothed roll crusher 5 is preferably a four-toothed roll crusher.

[0110] In the embodiment, the first multi-toothed roll crusher 1 is arranged above the second multi-toothed roll crusher 5, and is connected with the second multi-toothed roll crusher 5 through a chute ladder as a conveying device, so as to ensure that the falling materials after crushing by the first multi-toothed roll crusher 1 enter the second multi-toothed roll crusher 5 by gravity, thereby forming multi-stage crushing of the first multi-toothed roll crusher 1 and the second multi-toothed roll crusher 5.

[0111] In some embodiments, the second multi-toothed roll crusher 5 can also be used alone, for example, connected with an external feeder through a chute ladder, and the feeder is used to feed materials to the second multi-toothed roll crusher 5.

[0112] The discharge port of the second multi-toothed roll crusher 5 is connected with the inlet of the lifting device 2 through the first conveying device 6, specifically, the discharge port of the second multi-toothed roll crusher 5 is connected with the inlet of the first conveying device 6, so that the falling materials after the second crushing by the second multi-toothed roll crusher 5 are conveyed to the inlet of the lifting device 2 through the first conveying device 6, and the materials are lifted to a predetermined height by the lifting device 2, and the predetermined height corresponds to the inlet of the buffer bin 4.

[0113] Further, the discharge port of the lifting device 2 is connected with the inlet of the buffer bin 4 through the second conveying device 3, the falling materials are conveyed to the second conveying device 3 by the lifting device 2, and then the materials are transported to the inlet of the buffer bin 4 by the second conveying device 3.

[0114] The discharge port of the buffer bin 4 is provided below with a weighing belt 7 (equivalent to a third conveying device), which can not only convey the material, but also weigh the volume or weight of the material thereon, so that the material discharged from the buffer bin 4 is conveyed to the ball mill 14 after being weighed by the weighing belt 7. Here, the ball mill 14 is adopted to not only realize grinding by grinding, but also obtain coal gangue material meeting the particle size requirement.

[0115] Preferably, the discharge port of the buffer bin 4 is arranged opposite to the material inlet of the weighing belt 7, and the discharge port of the weighing belt 7 is arranged opposite to the material inlet of the ball mill 14, so as to ensure that the material can be accurately conveyed without being scattered.

[0116] Further, the material discharged from the discharge port of the buffer bin 4 is subjected to third crushing by the ball mill 14, and the coal gangue material after being ground and crushed by the ball mill 14 is conveyed into the buffer tank 13 for further mixing, and then filled into the underground goaf by the pumping device 12. The specific structure of the pumping device 12 here can be the same as that of the first embodiment.

[0117] In addition, the highest layer of the multi-layer frame structure 20, for example, the third layer 20a, is further provided with a dust removal device 8 and a water tank 9. The dust removal device 8 here can refer to the structure of the first embodiment, which will not be described herein.

[0118] In the embodiment, the device further includes a centralized control room 10 and a power distribution room 11, which can be arranged on the first layer 20a or the second layer 20b. The centralized control room 10 is provided with a centralized control system, which can realize independent start-stop control of a single device in the tower-type crushing and filling system, interlocking protection control of multiple processes according to the process, one-key start-stop control of the whole system, and different requirements of different users. The automatic control system can automatically control the start-stop of the whole system and the start-stop of the equipment during pipe blockage repair, and centralized control can reduce the operation difficulty, make the operation more convenient, and save the operation cost.

[0119] In the embodiment, the pulp filling process is realized by adopting the cooperation of multiple toothed roller crushers and ball mills. On the one hand, by adopting the toothed roller crusher to crush in multiple stages, the crushing of the material is relatively uniform, and then the particle size of the crushed coal gangue material is uniform after being ground by the ball mill, the powder content is high, the pulp is not easy to separate after being prepared, the pipeline resistance is small during filling, the underground diffusion is large, which is more beneficial to coal gangue filling, and the filling effect is good. By adopting the toothed roller crusher to crush in multiple stages, the particle size of the material entering the ball mill can be reduced, the purpose of more crushing and less grinding is achieved, and the power of the ball mill is reduced to save energy. On the other hand, the ball mill is installed on the ground by building a foundation, and one or more multiple toothed roller crushers are arranged on the main frame in the order of crushing. The size of the multiple toothed roller crusher is small, and the vibration is small, so the influence on the building is small, the overall land occupation area and height are effectively reduced, and the service life is prolonged.

[0120] In addition, considering that in the prior art, if a screening device is built for screening materials with qualified particle size, when the water content in the coal gangue is high, the screen is easy to be blocked. In the embodiment, the use of the ball mill can reduce the use of the screening device, effectively avoid the problem of screen blocking due to high water content in the coal gangue, reduce the process risk, reduce the operation cost, and improve the process efficiency.

[0121] The pulp filling process of the building type crushing and filling system in the embodiment is as follows: the coal gangue raw material is crushed by at least one multiple toothed roller crusher and then enters the buffer bin 4, is discharged from the buffer bin 4, is ground to a predetermined particle size by the ball mill 14, is mixed in the buffer tank 13, and is discharged to the underground filling area by the pumping device 12.

[0122] Based on the above embodiment, whether two-stage crushing, three-stage crushing, or more-stage crushing such as four-stage crushing, a variety of combination modes can be realized, wherein different crushing devices can be selected according to requirements. The variety of combination modes include but are not limited to "double toothed roller crusher + ball mill", "four toothed roller crusher + ball mill", "double toothed roller crusher + four toothed roller crusher + ball mill", "double toothed roller crusher + double toothed roller crusher + ball mill", "four toothed roller crusher + double toothed roller crusher + ball mill", "four toothed roller crusher + four toothed roller crusher + ball mill", "double toothed roller crusher + double toothed roller crusher + double toothed roller crusher + ball mill", "double toothed roller crusher + six toothed roller crusher + ball mill", "double toothed roller crusher + light roller crusher + ball mill", "four toothed roller crusher + light roller crusher + ball mill", and different forms such as wet mill.

[0123] The above specific embodiment adopts the "double-toothed roller crusher + four-toothed roller crusher + ball mill" as the preferred combination. In the multi-stage crushing combination of "double-toothed roller crusher + four-toothed roller crusher + ball mill", the first stage crushing realized by the double-toothed roller crusher can crush the material with a particle size of not more than 300 mm to below 80 mm, the second stage crushing realized by the four-toothed roller crusher can crush the material with a particle size of not more than 80 mm to below 10 mm, and finally the ball mill can crush the material below 10 mm to below 3 mm.

[0124] In the embodiment, when the "double-toothed roller crusher + four-toothed roller crusher + ball mill" is adopted, the multi-stage crushing realized before the ball mill can also reduce the feed particle size of the ball mill, achieve the purpose of more crushing and less grinding, reduce the power of the ball mill, and save energy consumption. For example, the feed particle size of the ball mill 14 is controlled to be not more than 10 mm, so that the particle size ratio of the plurality of multi-toothed roller crushers is controlled to be 4-5 stages, so that the coal gangue material can be crushed from 300 mm to below 10 mm based on three-stage crushing. Therefore, the combination of "double-toothed roller crusher + four-toothed roller crusher + ball mill" can simplify the crushing process, reduce cost and energy consumption, and reduce the replacement of wear parts.

[0125] In addition, compared with "four-toothed roller crusher + double-toothed roller crusher + ball mill", the combination of "double-toothed roller crusher + four-toothed roller crusher + ball mill" also has advantages. Since the four-toothed roller crusher has a small material throughput, is prone to blockage, and is not easy to disassemble and maintain, the four-toothed roller crusher is preferably used as the crushing device for the second stage crushing, which can effectively improve the problem of easy blockage of the four-toothed roller crusher.

[0126] The embodiment adopts a separate building body form and sets multi-stage crushing devices in the building body structure, so that the particle size of the crushed coal gangue material is uniform, the powder content is high, the slurry is not easy to separate after being prepared, the pipeline resistance is small during filling, the underground diffusion is large, the filling effect is improved, in addition, the overall land occupation is smaller, the devices in the building body are highly integrated, have multiple equipment and functions, the application of conveying devices is reduced during the process to save energy consumption, and the operation and maintenance are more convenient, which fully meets various requirements.

[0127] In addition, although each operation is described in a specific order, this should not be understood as requiring these operations to be performed in the specific order shown or in a sequential order. Under certain circumstances, multitasking and parallel processing may be advantageous. Similarly, although some specific implementation details have been included in the above discussion, these should not be interpreted as limiting the scope of the present invention. Some features described in the context of a separate embodiment can also be implemented in a single embodiment in combination.
