[0003] In the prior art, the gangue treatment device is constructed by flat ground infrastructure. After the gangue is crushed to a certain particle size, it is mixed with mixed additives (such as water, fly ash, cement, etc.), and then transported to the underground filling area (goaf, collapse area, separation area, accident pool, etc.). However, the flat ground infrastructure occupies a large ground area, has high construction costs, and high maintenance and operation costs, which has become a major pain point in the industry.

[0004] In addition to the above, there are also waste rock treatment devices constructed in the form of multiple towers. However, most of the buildings are reinforced concrete structures, which are complex to build, occupy a large area, and are high in height. There are many material conveying equipment connections between the crushing and screening equipment inside the building and between different buildings. The spatial layout is highly complex, which reduces the maintenance convenience of the equipment and increases the cost of maintenance. For areas with a small footprint, if you want to expand the filling system, you will not be able to carry out filling operations due to the footprint. Summary of the invention

More specifically, the material dividing device is a diverter chute, which includes a feed port and multiple outlet pipelines, and each of the outlet pipelines is equipped with a stop valve and a variable valve.

[0012] In order to allow the crushed materials to enter different secondary crushing devices, the material discharge ports of the two screening devices on the screen are connected to the feed ports of the two secondary crushing devices through chutes respectively, and the feed ports of the two secondary crushing devices are located directly below the material discharge ports of the two screening devices on the screen; a fourth belt conveyor is arranged directly below the material discharge ports of the two screening devices under the screen, and the material discharge ports of the two screening devices under the screen are connected to the feed port of the fourth belt conveyor.

[0023] Figure 1 It is a main schematic diagram of the building-type crushing and filling system of the utility model; Figure 2 It is a left side schematic diagram of the building type crushing and filling system of the utility model; Figure 3 This is a top view of the building-type crushing and filling system of the utility model. Figures 1 to 3 As shown, the utility model provides a building-type crushing and filling system, which is used to crush materials (raw materials) such as coal gangue, tailings and construction waste into particle sizes suitable for filling underground filling areas and then fill them.

[0024] The building type crushing and filling system includes a steel structure building 900, in which a crushing device, a screening device 400, a finished product bin 500 and a filling device are arranged. The crushing device is configured to crush the large particle size material into the material of the predetermined particle size, so that the crushed material is suitable for filling the underground filling area. The screening device 400 is configured to screen the crushed material and transport the crushed material according to the particle size of the crushed material. The finished product bin 500 is configured to receive the material with the predetermined particle size. The filling device is configured to mix the material from the finished product bin with the mixed additive and then transport it to the underground filling area.

[0025] Exemplarily, the crushing device includes one primary crushing device 110 and two secondary crushing devices 120, and the number of the screening devices 400 is two.

[0026] The building of the utility model is constructed with steel structure as a whole, without cement concrete, simple structure, short construction period, flexible and detachable; all equipment is installed in one building, occupying a smaller area. The steel structure building 900 can refer to the existing technology such as sand making building, which will not be described here. In order to make the building type crushing and filling system can be used in low temperature working environment (such as ambient temperature -30°C), an insulation layer is set on the outside of the steel structure building 900, and the insulation layer wraps the steel structure building 900.

[0027] The building-type crushing and filling system of the utility model also includes a conveying device for conveying materials. In different stages of material conveying, the conveying device can be in various forms. For example, the utility model can use a lifting device, a belt conveyor, a screw conveyor, a chute (a chute is a structure that directly connects the discharge port of one device to the feed port of another device, mainly used as a channel for gravity drop) and other devices for conveying materials in the prior art as conveying devices. For the transportation of materials in the horizontal direction or the approximately horizontal direction (the angle between the horizontal direction is less than or equal to 20°), the utility model preferably uses a belt conveyor, because the belt conveying is more reliable, easy to maintain, and has lower cost. For the transportation of materials in the vertical direction or the approximately vertical direction, the utility model preferably uses a lifting device, because the lifting device can be vertically and continuously conveyed, saving the size of the plane space. The lifting device can be an elevator, a bucket lift, a screw conveyor, etc. The utility model preferably uses an elevator as the lifting device, because the elevator can effectively save the size in the plane space. The utility model refers to the devices used for material transportation as conveying devices. In addition, in the process of conveying materials, a combination of various forms of conveying devices can be used, such as using a lifting device and a belt conveyor to jointly convey materials.

[0028] It should be added that, unless otherwise specified, the present invention does not limit the type of conveying device. For example, although the belt conveyor is used as an example below to transport materials in a horizontal or approximately horizontal direction, the belt conveyor can also be replaced by other applicable conveying devices in the prior art.

[0029] In the existing gangue filling technology, the material conveying equipment mainly adopts belt conveyor for conveying, that is, the belt conveyor is connected to the crusher discharge and sent to the screening machine feeding port. Since the belt conveyor has the limitation of the inclination angle, the material is easy to roll down when the inclination angle is too large. In order to meet the feeding requirements, the length of the belt conveyor is very long, and the overall equipment occupies a large area. The utility model adopts a lifting device as one of the conveying devices, which can directly lift the material to a certain height, reduce the layout of the belt conveyor, and the overall area is smaller. In addition, the utility model adopts a chute to realize the connection of the materials between the two devices, which can save a lot of conveying space and effectively reduce the floor area and height of the building-type crushing and filling system.

[0030] In the process of material crushing, it is difficult to crush all the materials to the required particle size at one time. Therefore, the utility model provides a primary crushing device 110 and a secondary crushing device 120 for crushing the materials together. The crushing device can be 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 used because the impact crusher has a relatively large crushing force, which can directly crush part of the materials to the target particle size or close to the target particle size, thereby reducing the operating pressure of the next stage of crushing.

[0031] The screening device 400 is configured to screen the crushed material and transport the crushed material according to the particle size of the crushed material. For example, the crushed material is transported to the secondary crushing device 120 or the finished product bin 500. More specifically, if the crushed material has met the requirements for filling the underground filling area, the crushed material is transported to the finished product bin 500; if the crushed material still does not meet the requirements for filling the underground filling area, the crushed material is transported to the secondary crushing device 120. The utility model does not limit the specific size of the particle size of the crushed material, and ordinary technicians in this field can design and select according to actual conditions.

[0032] The screening device 400 can adopt a relaxation screen, an air flow screen, a cylindrical screen, a single-stage vibrating screen, a multi-stage vibrating screen and a roller screen, etc. Preferably, the screening device 400 is a relaxation screen, and the screen is made of rubber. During operation, the screen is alternately tightened and relaxed, and the screen holes are constantly deformed, which increases the vibration degree of the screen surface and prevents the material from adhering to the screen and clogging the screen holes.

[0033] The crushing device (the primary crushing device 110 and the secondary crushing device 120) is arranged on the foundation, and the screening device 400 is arranged on the independent installation platform 910, and the independent installation platform 910 is arranged on the foundation. That is, the primary crushing device 110, the secondary crushing device 120 and the screening device 400 are independent of the steel structure building 900, and their installation and arrangement are not mutually dependent on the steel structure building 900. Except for the passage for passage, the primary crushing device 110, the secondary crushing device 120 and the screening device 400 are not connected to the steel structure building 900.

[0034] The primary crushing device 110 and the secondary crushing device 120 are directly connected to the foundation, and the screening device 400 is indirectly connected to the foundation through an independent mounting platform 910. This arrangement isolates the vibrations generated by the primary crushing device 110, the secondary crushing device 120 and the screening device 400 from affecting the steel structure building 900, and also avoids the impact of vibrations on other equipment on the steel structure building 900, reduces the load on the steel structure building 900, effectively extends the service life of the steel structure building 900, and provides effective conditions for concentrating all equipment in one tower.

[0035] The independent installation platform 910 may be a steel structure platform in the prior art, used to support the screening device 400. Exemplarily, the main body of the independent installation platform 910 may be composed of a mounting plane and a support frame, and the independent installation platform 910 is installed on the foundation. More specifically, the support frame is installed on the foundation, and a mounting plane is provided thereon, and the screening device 400 and the like are installed on the mounting plane.

[0036] The feeding system of the primary crushing device 110 is arranged outside the steel structure building 900. In order to match a variety of working environments, the present invention does not limit the structure and type of the feeding system.

[0037] For example, the feeding belt conveyor 810 of the feeding system can be directly connected to the coal washing plant, and the gangue washed by the coal washing plant is directly transported to the primary crushing device 110 through the feeding belt conveyor 810. This setting can reduce the use of equipment such as impurity removal and iron removal, thereby saving manpower and material resources.

[0038] Alternatively, the feeding system can be fed from a gangue bin / tank, in which case a feeding belt conveyor 810 is installed in the gangue bin / tank, a feeder 820 (such as a vibrating feeder, etc.) is installed above the feeding belt conveyor 810, and a filtering and impurity removal device 830 can be optionally installed above the feeder 820, and a forklift or direct material drop is used to feed the material to the filtering and impurity removal device 830, and the filtering and impurity removal device 830 filters large particles (>300mm), plastics, wood and other debris in the gangue raw stone through a filter screen, and then the feeder 820 transports the large particles (>300mm), plastics, wood and other debris to the feeding belt conveyor 810 for feeding. It should be noted that the feeding belt conveyor 810 is selected as the conveying device here, because in general, the feeding is long-distance feeding, and the feeding belt conveyor 810 has high versatility with the customer's equipment. Of course, the utility model is not limited to this, and other types of conveying devices can also be selected.

[0039] In order to remove iron materials from materials such as coal gangue, an iron remover 840 can be installed above the conveying device at the inlet and outlet of the primary crushing device 110. For example, the iron remover is arranged above the feeding belt conveyor 810. In addition, an independent dust removal device (dust removal point) can be installed at the conveying device for fixed-point dust removal.

[0040] By using the feeding belt conveyor 810 to feed the primary crushing device 110, it is more flexible. Combined with the filtering and impurity removal device 830 used when feeding the gangue bin / tank, the influence of large particles on the primary crushing is effectively eliminated through filtering, thus realizing the flexible application of the tower.

[0041] In order to facilitate the maintenance and replacement of wearing parts of the primary crushing device 110, a maintenance hoisting mechanism is provided above the primary crushing device 110, and the maintenance hoisting mechanism is installed on the steel structure building 900 through a hoisting bracket.

[0042] A first belt conveyor 210 is disposed below the discharge port of the primary crushing device 110 , and the discharge port of the primary crushing device 110 is connected to the feed port of the first belt conveyor 210 .

[0043] The discharge port of the first belt conveyor 210 is connected to the feed ports of two semi-finished product lifting devices 310 respectively through a material dividing device.

[0044] The material distribution device is used to transport the materials from the first belt conveyor 210 to the two semi-finished product lifting devices 310. The present invention does not limit the structure and type of the material distribution device, and the material distribution device, material distributor, etc. in the prior art can be used.

[0045] Exemplarily, in the present invention, the material dividing device may be a diverting chute. Figure 4 It is a schematic diagram of the main view of the diversion chute of the utility model; Figure 5It is a side view schematic diagram of the diverter chute of the utility model. The diverter chute 211 is designed with an automatically controlled switching system. For example, the diverter chute 211 includes a feed port 212 and multiple outlet pipelines 213 (in this embodiment, there are two outlet pipelines 213). After the material enters the diverter chute from the feed port 212, it flows out through multiple outlet pipelines 213, and each outlet pipeline 213 is installed with a stop valve 214 and a variable valve 215; the stop valve 214 can choose two control modes, automatic and manual control, which can make the outlet pipeline 213 fully open or fully closed, and does not have the function of regulating flow; the variable valve 215 is an automatically controlled valve, which can adopt various control methods such as electric and pneumatic, without manual intervention, and the switch state can be accurately controlled. The material flow can be adjusted according to needs to improve production efficiency and achieve uniform material distribution. The material enters the diverter chute 211 from the feed port 212 and then enters each outlet pipeline 213, first passes through the variable valve 215 and then passes through the stop valve 214, so that the pipeline can be closed more thoroughly, and automatic control switching of production capacity can be achieved. In addition to the above, other types of diverter chute 211 designs that can be automatically controlled in the prior art can also be used. It should be added that the diverter chute 211 can be set inclined or vertically.

[0046] The two semi-finished product lifting devices 310 are located between the two screening devices 400. The discharge ports of the two semi-finished product lifting devices 310 are respectively connected to the feed ports of the two screening devices 400 through chutes. Exemplarily, the two semi-finished product lifting devices 310 are both arranged on a foundation.

[0047] The two screening devices 400 are installed on an independent installation platform 910 and the independent installation platforms 910 of the two screening devices 400 are independent of each other.

[0048] The oversize material discharge ports of the two screening devices 400 are connected to the feed ports of the two secondary crushing devices 120 through chutes, respectively, and the feed ports of the two secondary crushing devices 120 are respectively located directly below the oversize material discharge ports of the two screening devices 400. The oversize material (for example, with a particle size ≥ 3 mm) enters the secondary crushing device 120 through the chute.

[0049] The discharge ports of the two secondary crushing devices 120 are respectively connected to the feed ports of the two third belt conveyors 230. The feed ports of the two third belt conveyors 230 are respectively located directly below the discharge ports of the two secondary crushing devices 120. The discharge ports of the two third belt conveyors 230 are connected to the feed port of the first belt conveyor 210 (the first belt conveyor 210 and other belt conveyors may have multiple feed ports), and the crushed screened materials are transported to the screening device 400 again through the first belt conveyor 210 for subsequent processing.

[0050] A fourth belt conveyor 240 is provided directly below the discharge ports of the undersize materials of the two screening devices 400 . The discharge ports of the undersize materials of the two screening devices 400 are connected to the feed ports of the fourth belt conveyor 240 , and the undersize materials directly fall onto the fourth belt conveyor 240 .

[0051] More specifically, the feed port of the fourth belt conveyor 240 is located directly below the discharge ports of the under-screened materials of the two screening devices 400. The discharge port of the fourth belt conveyor 240 is connected to the feed port of the finished product lifting device 320. The finished product lifting device 320 is located on the side of the screening device 400, and the discharge port of the finished product lifting device 320 is connected to the feed port of the second belt conveyor 220, and the discharge port of the second belt conveyor 220 is connected to the feed port of the finished product bin 500.

[0052] From the above, it can be seen that a chute is provided between the discharge ports of the two semi-finished product lifting devices 310 and the feed ports of the two screening devices 400 in the building-type crushing and filling system of the utility model, and a chute is provided between the discharge ports of the screened materials of the two screening devices 400 and the feed ports of the two secondary crushing devices 120, which use gravity to flow to the lower-level equipment, thereby reducing the application of the conveying device and the maintenance work of the whole system. At the same time, the chute design saves a lot of conveying space and effectively reduces the floor space and height of the tower. In addition, the process route of two-stage crushing and more screening and less crushing is adopted, which realizes energy saving and consumption reduction of the crushing device and the screening device 400, increases the material cost advantage, and improves the finished product rate of gangue crushing and the proportion of powder.

[0053] Furthermore, the utility model adopts a double lifting device (semi-finished product lifting device 310) for loading, and each semi-finished product lifting device 310 corresponds to a screening device 400 and a secondary crushing device 120 respectively. Combined with the design of the diversion chute 211, the operation of any set of semi-finished product lifting device 310-screening device 400-secondary crushing device 120 can be realized, which not only provides a backup system for equipment maintenance, but also can switch equipment according to the requirements of the filling volume to adjust the system output, which can effectively reduce the equipment operation cost, realize non-stop maintenance, and meet the continuous operation requirements of mixing and filling.

[0054] A weighing belt conveyor 280 is provided directly below the discharge port of the finished product bin 500. The discharge port of the weighing belt conveyor 280 is connected to the feed port of the filling device.

[0055] The filling device is configured to mix the material from the finished product bin 500 with mixed additives (such as water, fly ash, cement, etc.), and transport the mixed material to the underground filling area.

[0056] In order to prevent inappropriate materials from being injected into the underground filling area when a fault occurs, the filling device can also transport the materials to an accident pool (such as a separation zone, etc.).

[0057] The filling device includes a mixing device and a pumping device. The inlet of the mixing device is connected to the outlet of the weighing belt conveyor 280. The mixing device is used to mix the measured materials in the finished product bin 500 with the mixed additives into slurry and then transmit it to the pumping device through the discharge manifold. The pumping device is used to transport the mixed materials to the underground filling area.

[0058] The mixing device may be a vertical mixing device or a horizontal mixing device (such as a single-shaft horizontal mixer, a double-shaft horizontal mixer), etc., and the pumping device may be a plunger pump, a mud pump, a slurry pump, a centrifugal pump or a vane pump, etc.

[0059] In order to reduce dust pollution and improve the utilization rate of materials, the building type crushing and filling system also includes a dust removal device, which can be placed directly on the foundation or installed on the steel structure building 900. In order to save space, the dust removal device is located at a higher place (such as the 2nd and 3rd floors) of the steel structure building 900. The utility model does not limit the structure and type of the dust removal device. For example, the dust removal device can be an electrostatic dust collector, a bag dust collector, a cyclone dust collector, a wet dust collector, a cartridge dust collector, etc.

[0060] Exemplarily, the dust removal device may include a screw conveyor 710, a discharge valve (such as a star valve), a dust collection pipeline, a dust collector 730, a dust removal fan 740, etc. The dust removal fan 740 is connected to the air outlet of the dust collector 730, one end of the dust collection pipeline is connected to the air inlet of the dust collector 730, and the other end is connected to the dust collection point. The discharge port of the screw conveyor 710 is connected to the feed port of the finished product lifting device 320; the dust removal fan 740 drives the dust-containing gas at each dust collection point to enter the dust collector 730 through the dust collection pipeline. 30, the dust-containing gas is filtered by the dust collector 730, enters the dust removal fan 740 through the air outlet of the dust collector 730, and is discharged from the air outlet of the dust removal fan 740; the filtered powder is cleaned by the dust collector 730 and falls into the ash hopper of the dust collector 730, and the powder in the ash hopper is unloaded into the screw conveyor 710 through the discharge valve of the discharge port of the dust collector 730, and the powder is transported to the finished product lifting device 320 through the screw conveyor 710, and then finally reaches the finished product warehouse 500 through the second belt conveyor 220. The screw conveyor is used here to transport dusty materials, which can ensure uniform material delivery and no dust, and the utility model does not directly transport the powder to the finished product warehouse 500, which can control the powder content of the material in the finished product warehouse 500 and avoid uneven powder content of the material in the finished product warehouse 500. The above-mentioned setting can effectively reduce the overall height of the building-type crushing and filling system, and provide conditions for the integrated tower solution.

[0061] The present invention does not limit the location of the dust collection point, and those skilled in the art can design and select according to needs. For example, the dust collection point can be set at the inlet and outlet of the primary crushing device 110 and the secondary crushing device 120, near the screening device 400, and at the drop point connected between the conveying devices. It should be noted that the dust collection point should be separated from the drop point by a distance to avoid taking away the finished materials.

[0062] In order to facilitate equipment maintenance or debugging, the steel structure building 900 includes a floor, stairs or elevator for personnel to pass through. In order to save space, when stairs are used, the stairs are arranged around the semi-finished product lifting device 310. Personnel can reach different positions of the steel structure building 900 and maintenance points of various components of the building-type crushing and filling system (such as maintenance points of the lifting device) through the floor, stairs or elevator.

[0063] The utility model can change the number of floors and height of the steel structure building 900. For example, an additional floor can be set above the finished product warehouse 500, and the emergency water tank 510 can be set above the finished product warehouse 500. The emergency water tank 510 reserves emergency water, which can be used for emergency water and equipment pipeline cleaning by gravity flow, realizing the non-powered application of emergency water and saving energy consumption.

[0064] It should be noted that, as needed, the building-type crushing and filling system may also include emergency lighting, a monitoring system, etc. A solar panel may be added to the top of the building-type crushing and filling system to use solar power generation to supply internal lighting, emergency power supply, and monitoring equipment, etc., thereby saving energy and ensuring normal use of the lighting and monitoring equipment inside the tower during power outages.

[0065] The working process of the building-type crushing and filling system of the utility model is introduced below with reference to specific examples.

[0066] The primary crushing device 110 is loaded with a belt conveyor. Raw materials such as coal gangue and raw stone are transported to the feeding port of the primary crushing device 110 through the loading belt conveyor 810, and fall onto the first belt conveyor 210 after being crushed. After being divided by the diversion chute 211, they fall into two semi-finished product lifting devices 310 respectively. The two semi-finished product lifting devices 310 lift the materials to the feeding height of the screening device 400, and throw the materials into the screening device 400 respectively; the screened materials of the two screening devices 400 flow into the two secondary crushing devices 120 respectively through the chute, and the materials after the secondary crushing are transported to the first belt conveyor 210 through the third belt conveyor 230 for re-screening; the under-screened materials of the two screening devices 400 enter the fourth belt conveyor 240 and are transported to the feeding port of the finished product lifting device 320. The finished product lifting device 320 transports the materials to the second belt conveyor 220 and then enters the finished product warehouse 500. The material falls onto the weighing belt conveyor 280, and enters the inlet of the filling device from the outlet of the weighing belt conveyor 280 for filling and other processing.
