Background Art

[0002] With the continuous exploitation of coal, the demand for gangue filling treatment in China increases year by year. At present, the coal gangue raw materials used in the filling production line are mostly washed coal gangue, and the moisture content of the washed materials is relatively large. When such materials enter the inside of the finished product tank, it is extremely easy to cause abnormal blanking and lead to abnormal operation of downstream links.

[0003] At present, the finished product tanks in the filling industry and downstream links are mostly independently connected and do not realize the relationship of mutual backup. This will lead to the phenomenon that if there is material caking or abnormal blockage inside a certain finished product tank, then the entire process line will be forced to stop for maintenance. This will greatly affect the stability of filling and the continuous operation of upstream and downstream equipment. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a multi-tank blanking device for a building-type crushing and filling system aiming at the deficiencies of the prior art.

[0007] In order to prevent and eliminate plugging phenomena such as caking in the finished product bin and make the materials attached to the side wall of the finished product bin fall off cleanly, a bin vibrator is arranged on the side wall of the finished product bin.

[0025] Figure 1 This is a structural block diagram of the building-type crushing and filling system of the present utility model; Figure 2 This is a front view schematic diagram of the building-type crushing and filling system of the present utility model; Figure 3 This is a top view schematic diagram of the building-type crushing and filling system of the present utility model; Figure 4 This is a left view schematic diagram of the building-type crushing and filling system of the present utility model; Figure 5 This is a right view schematic diagram of the building-type crushing and filling system of the present utility model. As Figures 1 to 5 shown, the present utility model provides a building-type crushing and filling system for crushing materials (raw materials) such as coal gangue, tailings, and construction waste into a particle size suitable for filling the underground filling area 630 and performing filling.

[0026] The building-type crushing and filling system includes a steel structure building body 900, and a crushing device, a screening device 400, a finished product bin 500, and a filling device are arranged in the steel structure building body 900. The crushing device is configured to crush materials of a large particle size level into materials of a predetermined particle size level, so that the crushed materials are suitable for filling the underground filling area 630. The screening device 400 is configured to screen the crushed materials and convey the crushed materials according to the particle size of the crushed materials. The finished product bin 500 is configured to receive the materials with the predetermined particle size. The filling device is configured to mix the materials from the finished product bin with a mixed additive and then convey them to the underground filling area.

[0027] Exemplarily, the crushing device includes a primary crushing device 110 and two secondary crushing devices 120, and the number of the screening devices 400 is two.

[0028] The whole building body of the present utility model is built with a steel structure, without the need for cement concrete construction, with a simple structure, a short construction period, and flexible disassembly; all equipment is centrally installed in one building body, occupying a smaller area. The steel structure building body 900 can refer to existing technologies such as the building body of a sand making building, and will not be elaborated here.

[0029] The floor-type crushing and backfilling system of the present utility model further includes a conveying device for conveying materials. At different conveying stages of the materials, the conveying device can be in various forms. For example, the present 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 passage for gravity feeding), and other devices for conveying materials in the prior art as the conveying device. For the transportation of materials in the horizontal direction or an approximately horizontal direction (the included angle with the horizontal direction is less than or equal to 20°), the present utility model preferably uses a belt conveyor because belt conveying is more reliable, convenient for maintenance, and has lower costs. For the transportation of materials in the vertical direction or an approximately vertical direction, the present utility model preferably uses a lifting device because the lifting device can continuously convey vertically and save the planar space size. The lifting device can be a hoist, a bucket elevator, a screw conveyor, etc. The present utility model preferably uses a hoist as the lifting device because the hoist can effectively save the size in the planar space. The present utility model collectively refers to the devices used for material conveying as the conveying device. Additionally, during the process of conveying materials, a combination of various forms of conveying devices can also be used. For example, a lifting device and a belt conveyor can be used together for material conveying.

[0030] It should be added that unless otherwise specified, the present utility model does not limit the types of conveying devices. For example, although a belt conveyor is used as an example for the transportation of materials in the horizontal direction or an approximately horizontal direction in the following text, the belt conveyor can also be replaced by other applicable conveying devices in the prior art.

[0031] In the existing gangue backfilling technology, the material conveying equipment mainly uses a belt conveyor for conveying, that is, the belt conveyor is connected to the discharge of the crusher and sent to the feed port of the screening machine. Due to the inclination limit of the belt conveyor, when the inclination is too large, the materials are likely to roll down. In order to meet the feeding requirements, the length of the belt conveyor is very long, and the overall floor area of the equipment is very large. The present utility model uses a lifting device as one of the conveying devices, which can directly lift the materials to a certain height, reduce the layout of the belt conveyor, and the overall floor area is smaller.

[0032] During the process of material crushing, since it is difficult to crush all the materials to the required particle size at one time, therefore, in the present utility model, a primary crushing device 110 and a secondary crushing device 120 are provided and jointly used for material crushing. The crushing device can adopt a jaw crusher, a gyratory crusher, a cone crusher, a roll crusher, a hammer crusher, a counterattack crusher, etc. Preferably, a counterattack crusher is adopted because the counterattack crusher has a large crushing ratio, can directly crush some materials to the target particle size or close to the target particle size, and reduce the operation pressure of the next-stage crushing.

[0033] The screening device 400 is configured to screen the crushed material and convey the crushed material according to the particle size of the crushed material. For example, the crushed material is conveyed to the secondary crushing device 120 or the finished product bin 500. More specifically, if the crushed material already meets the requirements for filling the underground filling area 630, then the crushed material is conveyed to the finished product bin 500; if the crushed material does not yet meet the requirements for filling the underground filling area 630, then the crushed material is conveyed to the secondary crushing device 120. The present utility model does not limit the specific size of the particle size of the crushed material, and those of ordinary skill in the art can make design selections according to the actual situation.

[0034] The screening device 400 can be a relaxation screen, an air screen, a cylindrical screen, a single-stage vibrating screen, a multi-stage vibrating screen, a roller screen, etc. Preferably, the screening device 400 is a relaxation screen, and the screen mesh is made of rubber. During operation, the screen mesh is alternately tightened and relaxed, and the screen holes are constantly deformed, increasing the vibration degree of the screen surface, avoiding material adhesion to the screen mesh and clogging of the screen holes.

[0035] The primary crushing device 110, the secondary crushing device 120, and the screening device 400 are respectively arranged on their respective independent installation platforms 910, and the independent installation platforms 910 are independent of the steel structure building 900. In other words, the installation and setting of the independent installation platforms 910 are not mutually dependent on the steel structure building 900. Except for passages for passage, etc., the independent installation platforms 910 are not connected to the steel structure building 900. Further, the multiple independent installation platforms 910 are independent of each other and not connected to each other. The independent independent installation platforms 910 effectively prevent the equipment such as the primary crushing device 110, the secondary crushing device 120, and the screening device 400 from driving the steel structure building 900 to vibrate, and also avoid the influence of vibration on other equipment on the steel structure building 900. At the same time, the load on the steel structure building 900 is reduced, and the service life of the building-type crushing and filling system is extended.

[0036] The independent installation platform 910 can be a steel structure platform in the prior art for supporting the primary crushing device 110, the secondary crushing device 120, and the screening device 400. Exemplarily, the main body of the independent installation platform 910 can be composed of an installation plane and a support frame, and each independent installation platform 910 is installed on the ground. More specifically, the support frame is installed on the ground, and an installation plane is provided thereon, and the primary crushing device 110, the secondary crushing device 120, the screening device 400, etc. are installed on the installation plane.

[0037] The primary crushing device 110 is located inside the steel structure building 900 and is indirectly installed on the ground through the independent installation platform 910. The feeding system of the primary crushing device 110 is arranged outside the steel structure building 900. In order to match various operating environments, the present utility model does not limit the structure and type of the feeding system.

[0038] For example, the feeding belt conveyor 810 of the feeding system can be directly connected to the coal preparation plant, and the coal gangue washed out by the coal preparation plant can be directly conveyed into the primary crushing device 110 through the feeding belt conveyor 810.

[0039] Alternatively, the feeding system can use a coal gangue bin / tank for feeding. At this time, the feeding belt conveyor 810 is installed inside the coal gangue bin / tank, a feeder 820 is installed above the feeding belt conveyor 810, and a filtering and impurity removal device 830 can be optionally built above the feeder 820. The filtering and impurity removal device 830 filters out impurities and large particle materials, etc., and after filtering, it falls into the feeder 820. The feeder 820 conveys the materials 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 generally the feeding is for long-distance feeding, and the feeding belt conveyor 810 has high versatility with customer equipment. Of course, the present utility model is not limited thereto, and other types of conveying devices can also be selected.

[0040] In order to remove iron-containing materials in materials such as coal gangue, a magnetic separator 840 can be installed above the conveying devices at the inlet and outlet of the primary crushing device 110. For example, the magnetic separator 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.

[0041] By using the feeding belt conveyor 810 to feed the primary crushing device 110, the flexibility is relatively high. Combined with the filtering and impurity removal device 830 used in the coal gangue bin / tank feeding, the influence of large particle materials on the primary crushing is effectively excluded through filtering, realizing the flexible application of the tower.

[0042] In order to facilitate the maintenance and replacement of vulnerable parts of the primary crushing device 110, a hoisting mechanism for maintenance is arranged above the primary crushing device 110, and the hoisting mechanism for maintenance is installed on the steel structure building 900 through a hoisting bracket.

[0043] A first belt conveyor 210 is arranged below the outlet of the primary crushing device 110, and the outlet of the primary crushing device 110 is connected to the inlet of the first belt conveyor 210. The first belt conveyor 210 can be installed above or below the ground according to the actual working conditions.

[0044] 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 diversion chute 211. The two semi-finished product lifting devices 310 are symmetrically distributed on both sides of the first belt conveyor 210, and the feed ports of the two semi-finished product lifting devices 310 face the first belt conveyor 210.

[0045] Figure 6 It is the front view schematic diagram of the diversion chute of the present utility model; Figure 7 It is the side view schematic diagram of the diversion chute of the present utility model. The diversion chute 211 is designed with an automatically controlled switching system. Exemplarily, the diversion chute 211 includes a feed port 212 and multiple outlet pipelines 213 (in this embodiment, the number of outlet pipelines 213 is two). After the material enters the diversion chute from the feed port 212, it flows out through the multiple outlet pipelines 213, and a stop valve 214 and a variable valve 215 are installed on each outlet pipeline 213; the stop valve 214 can select two control modes of automatic and manual control, which can fully open or fully close the outlet pipeline 213 and does not have the function of regulating the flow rate; the variable valve 215 is an automatically controlled valve, which can adopt multiple control methods such as electric and pneumatic, without manual intervention, and the on-off state can be precisely controlled. According to needs, the flow rate of the material is adjusted to improve the production efficiency and achieve uniform material distribution. After the material enters the diversion chute 211 from the feed port 212 and enters each outlet pipeline 213, it first passes through the variable valve 215 and then through the stop valve 214, which can make the pipeline close more thoroughly and realize automatic control of switching production capacity. In addition to the above, other types of diversion chutes 211 that can be automatically controlled in the prior art can also be used in the design. It should be added that the diversion chute 211 can be inclined or vertical.

[0046] Below the discharge ports of the two semi-finished product lifting devices 310, second belt conveyors 220 are respectively arranged, and the discharge ports of the semi-finished product lifting devices 310 are connected to the feed ports of the second belt conveyors 220. Exemplarily, the second belt conveyors 220 are located on the top floor of the steel structure building 900.

[0047] The discharge ports of the two second belt conveyors 220 are respectively connected to the feed ports of two screening devices 400 through chutes, and the feed ports of the two screening devices 400 are located directly below the discharge ports of the chutes. The two screening devices 400 are installed on independent installation platforms 910, and the independent installation platforms 910 of the two screening devices 400 are independent of each other.

[0048] In other words, two screening devices 400, two semi-finished product lifting devices 310, and two of the second belt conveyors 220 are symmetrically distributed on both sides of the first belt conveyor 210, such that the materials conveyed from the first belt conveyor 210 can be screened by two sets of screening equipment respectively.

[0049] Two of the secondary crushing devices 120 are also symmetrically distributed on both sides of the first belt conveyor 210. The oversize material discharge ports of the two screening devices 400 are respectively connected to the feeding ports of the two secondary crushing devices 120 through chutes. The feeding 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 materials enter the secondary crushing devices 120 through the chutes.

[0050] The discharge ports of the two secondary crushing devices 120 are respectively connected to the feeding ports of the two third belt conveyors 230. The feeding 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 feeding port of the first belt conveyor 210 (belt conveyors such as the first belt conveyor 210 can have multiple feeding ports). The crushed oversize materials are conveyed again to the screening devices 400 through the first belt conveyor 210 for subsequent processing.

[0051] In other words, two secondary crushing devices 120 are also symmetrically distributed on both sides of the first belt conveyor 210, such that the oversize materials screened by the two sets of screening equipment can be re-crushed by the two secondary crushing devices 120 respectively.

[0052] A fourth belt conveyor 240 is provided directly below the undersize material discharge ports of the two screening devices 400. The undersize material discharge ports of the two screening devices 400 are connected to the feeding port of the fourth belt conveyor 240. The undersize materials directly fall onto the fourth belt conveyor 240.

[0053] More specifically, the feeding port of the fourth belt conveyor 240 is located directly below the undersize material discharge ports of the two screening devices 400 and above the first belt conveyor 210. The discharge port of the fourth belt conveyor 240 is connected to the feeding port of the finished product lifting device 320 through a chute. The finished product lifting device 320 is located on the side of the screening device 400. The discharge port of the finished product lifting device 320 is connected to the feeding port of the fifth belt conveyor 250. The discharge port of the fifth belt conveyor 250 is connected to the feeding port of the two-way belt conveyor 260. The discharge ports at both ends of the two-way belt conveyor 260 are respectively connected to the feeding ports of the two finished product bins 500 through the diverting device 290. The materials are conveyed into the two finished product bins 500 by the forward and reverse rotation of the two-way belt conveyor 260.

[0054] The shunt device 290 includes a feed inlet and a plurality of shunt pipelines. Each shunt pipeline is inserted into the corresponding finished product bin 500, and a plurality of discharge holes are provided in the part of the shunt pipeline inserted into the finished product bin 500.

[0055] During the process of the material (finished product material) falling into the finished product bin 500, larger particles of the material will segregate from the dropping point to the surrounding after entering the finished product bin 500, resulting in uneven distribution of the material in the bin and affecting the mixing effect. By setting the shunt device 290, the number of dropping points can be increased, material segregation can be reduced, and the material in the bin can be made more uniform.

[0056] It should be noted that the present utility model does not limit the number and size of the finished product bins 500.

[0057] As can be seen from the above, the building type crushing and filling system of the present utility model adopts a process route of two-stage crushing and multi-screening and less crushing, realizes energy conservation and consumption reduction of the crushing device and the screening device 400, increases the cost advantage of the material properties, and improves the finished product rate of gangue crushing and the proportion of powder materials.

[0058] In addition, the present utility model uses a double-lifting device (semi-finished product lifting device 310) for feeding. 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 shunt 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 standby system during equipment maintenance, but also can switch the equipment according to the requirements of the filling volume to adjust the system output, and can effectively reduce the equipment operation cost.

[0059] A weighing belt conveyor 280 for transporting materials bidirectionally is arranged directly below the discharge port of the finished product bin 500. The discharge ports at both ends of the weighing belt conveyor 280 are respectively connected to the feed inlets of two filling devices.

[0060] 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 630. Exemplarily, the number of the filling devices is two.

[0061] In order to avoid injecting inappropriate materials into the underground filling area 630 in case of a failure, the filling device can also transport the material to an accident pool (such as a separated layer area, etc.).

[0062] The filling device includes a mixing device 610 and a pumping device 620. The inlet of the mixing device 610 is connected to the outlet of the weighing belt conveyor 280. The mixing device 610 is used to mix the materials in the metered finished product bin 500 with the mixed additive into a slurry and then transfer it to the pumping device 620 through the discharge manifold. The pumping device 620 is used to transport the mixed materials to the underground filling area 630.

[0063] The mixing device 610 can be a vertical mixing device or a horizontal mixing device (such as a single-shaft horizontal mixer, a double-shaft horizontal mixer), etc. The pumping device 620 can be a plunger pump, a mud pump, a slurry pump, a centrifugal pump or a vane pump, etc.

[0064] During operation, different filling devices can be replaced by adjusting the conveying direction of the weighing belt conveyor 280. For example, two filling devices can be used in a standby mode.

[0065] As described above, in the above embodiment, two finished product bins 500 are used for feeding the filling device. The present invention is not limited thereto. In order to solve the problem that the whole process line is forced to stop for maintenance due to material caking or abnormal blockage inside a certain finished product bin, the number of the finished product bins 500 of the present invention is more than two.

[0066] Hereinafter, an example with three finished product bins 500 will be used for exemplary illustration.

[0067] Figure 8 It is the front view schematic diagram of the multi-bin feeding device for the building type crushing and filling system of the present invention; Figure 9 It is the three-dimensional schematic diagram of the multi-bin feeding device for the building type crushing and filling system of the present invention. As Figure 8 and Figure 9 shown, the present invention provides a multi-bin feeding device for a building type crushing and filling system, including a shunt device 290, at least two (three here) finished product bins 500 and a weighing belt conveyor 280 arranged in sequence along the conveying direction of the materials.

[0068] The shunt device 290 includes a shunt inlet 291 and at least two shunt pipelines 292. One end of each shunt pipeline 292 is communicated with the shunt inlet 291, and the other end is inserted into the corresponding finished product bin 500. The number of the shunt pipelines 292 is the same as the number of the finished product bins 500. Here, the number of the finished product bins 500 is three, and the number of the shunt pipelines 292 is also three. When three shunt pipelines 292 and three finished product bins 500 are adopted,

[0069] In order to control the transmission path of materials when entering the finished product bin 500, a blanking valve 293 is provided in each of the shunt pipelines 292. The blanking valve 293 can be a knife gate valve, a rotary seal valve, a gravity valve, etc., and a knife gate valve is preferably used. In order to more precisely control the material transmission, the blanking valve 293 is arranged in the middle section of the shunt pipeline 292. The blanking valve 293 can be connected to the shunt pipeline 292 through a flange or the like, for example.

[0070] In order to control the transmission path of materials when leaving the finished product bin 500, a blanking valve 293 is provided at the bottom of each of the finished product bins 500.

[0071] By controlling the opening and closing of the blanking valves 293 at different positions, the materials can be controlled to enter different finished product bins 500, or the materials can be made to enter the weighing belt conveyor 280 from different finished product bins 500. Alternatively, multiple finished product bins 500 can also discharge materials simultaneously.

[0072] In order to prevent and eliminate plugging phenomena such as caking in the finished product bin 500 and make the materials attached to the side wall of the finished product bin fall off cleanly, a bin vibrator (not shown in the figure) is provided on the side wall of the finished product bin 500. The present invention does not limit the type of the bin vibrator, and those skilled in the art can design and select based on the actual situation on the basis of the existing technology. By means of the bin vibrator, the materials in the finished product bin 500 are vibrated, thereby reducing caking of the materials and facilitating blanking.

[0073] The weighing belt conveyor 280 is provided with a weighing device for detecting the weight of the materials on the weighing belt conveyor 280. The weighing belt conveyor 280 further includes a driving motor 281. By controlling the operation (forward rotation, reverse rotation, stop rotation, etc.) of the driving motor 281, the start-stop and conveying direction of the weighing belt conveyor 280 can be controlled, so as to convey materials to different filling devices and realize one standby and one use of two filling devices.

[0074] In addition, when the weighing device of the weighing belt conveyor 280 detects an abnormality, for example, when the weighing device detects that the material supply is insufficient for a set time (at this time, the materials in the currently discharging finished product bin 500 may be exhausted or caking occurs), the blanking valve 293 that has not been opened can be automatically or manually opened to enable the unused finished product bin 500 to start discharging materials, thereby realizing real-time replenishment of materials.

[0075] Furthermore, in addition to controlling the opening and closing of the blanking valve 293, the blanking speed of the materials can also be controlled by controlling the belt speed of the weighing belt conveyor 280.

[0076] As described above, through the above structure, the utility model can control the feeding path of materials during the feeding process. When a failure occurs in the conveying, the opening and closing of the feeding valve 293 can be controlled to close the faulty conveying path, and other conveying paths can be used for feeding, which greatly avoids aggravating the problems of the production line with problems and realizes the continuous operation of the entire production line.

[0077] To reduce dust pollution and improve the utilization rate of materials, the building-type crushing and filling system further includes a dust removal device, which can be directly placed on the ground or installed on the steel structure building 900. To save space, the dust removal device is located on the side of the semi-finished product lifting device 310. 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 precipitator, a bag filter, a cyclone dust collector, a wet dust collector, a cartridge dust collector, etc.

[0078] Exemplarily, the dust removal device can include a screw conveyor 710, a discharge valve 720, 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 dust removal fan 740 drives the dust-containing gas at each dust collection point to enter the interior of the dust collector 730 through the dust collection pipeline. The dust-containing gas is filtered by the dust collector 730 and then enters the dust removal fan 740 through the air outlet of the dust collector 730 and is discharged from the exhaust port of the dust removal fan 740. The filtered powder falls into the ash hopper of the dust collector 730 after being cleaned by the dust collector 730. The powder in the ash hopper is unloaded into the screw conveyor 710 through the discharge valve 720 at the discharge port of the dust collector 730. The powder is conveyed to the fourth belt conveyor 240 by the screw conveyor 710 (the discharge port of the screw conveyor is connected to the inlet of the fourth belt conveyor), and finally reaches the finished product bin 500. Here, a screw conveyor is selected to convey the dust materials, which can ensure uniform feeding without dust raising. And the utility model does not directly convey the powder to the finished product bin 500, which can control the powder content of the materials in the finished product bin 500 and avoid uneven powder content of the materials in the finished product bin 500.

[0079] The utility model does not limit the setting position of the dust collection points, and those skilled in the art can design and select according to needs. For example, the dust collection points can be set at the inlet and outlet of the primary crushing device 110, the secondary crushing device 120, near the screening device 400, and at the material dropping points connected between the conveying devices. Figure 1 The circular shape in shows schematically the setting position of the dust collection points. It should be noted that the dust collection points should be spaced from the material dropping points to avoid collecting the finished products as well.

[0080] For the convenience of equipment maintenance, debugging, etc., the steel structure building 900 includes a floor slab, stairs or an elevator for personnel passage. To save space, when stairs are adopted, the stairs are arranged around the semi-finished product lifting device 310. Personnel can reach different positions of the steel structure building 900 and the maintenance points of each component in the building-type crushing and filling system (such as the maintenance point of the lifting device) through the floor slab, stairs or elevator.

[0081] To save costs, the upper surface of the finished product bin 500 is part of the top floor of the steel structure building 900. Of course, the present invention is not limited thereto, and the number of floors and height of the steel structure building 900 can also be changed. For example, additional floors can also be provided above the finished product bin 500, and the emergency water tank 510, etc. can be arranged above the finished product bin 500. The emergency water tank 510 can be used for the maintenance of the material conveying device in the finished product bin 500.

After being divided by the diversion chute 211, they respectively fall into the two semi-finished product lifting devices 310. The two semi-finished product lifting devices 310 lift the materials to the feeding height of the screening device 400 and respectively throw the materials onto the two second belt conveyors 220 of the screening device 400. The two second belt conveyors 220 respectively convey the materials to the chute at the feeding port of the screening device 400 so that the materials enter the screening device 400; the oversize materials of the two screening devices 400 flow into the two secondary crushing devices 120 through the chute respectively, and the materials after secondary crushing are conveyed to the first belt conveyor 210 through the third belt conveyor 230 for re-screening; the undersize materials of the two screening devices 400 enter the fourth belt conveyor 240 and are conveyed to the feeding port of the finished product lifting device 320. The finished product lifting device 320 lifts the materials to the feeding height of the diversion device 290. The materials enter the two-way belt conveyor 260 after passing through the fifth belt conveyor 250, and the two-way belt conveyor 260 conveys the materials into the diversion device 290 and then flows into the finished product bin 500.

[0084] During this process, the dust removal fan 740 of the dust removal device drives the dust generated during the crushing and screening processes. After being filtered by the dust collector 730, the dust is concentrated in the ash hopper of the dust collector 730. The dust in the ash hopper is controlled to fall into the screw conveyor 710 through the discharge valve 720. The screw conveyor 710 transports the powder material into the fourth belt conveyor 240 and finally sends it to the finished product bin 500. The material falls onto the weighing belt conveyor 280 for two-way material transportation and enters the feeding ports of two filling devices from the discharge ports at both ends of the weighing belt conveyor 280 for filling.
