[0002] Cemented filling mining is an important means for underground mining to control geological disasters and ground pressure risks, improve resource utilization, and achieve green and environmentally friendly mining. For example, Chinese patent document CN113087480A discloses an application-type cemented filling material containing ultra-fine tailings and its preparation method and application. The solid waste cemented filling material is composed of four components: converter slag, blast furnace ore powder, desulfurized ash and desulfurized gypsum. These materials will be mixed during filling. Therefore, the mixing device is a common equipment for cemented filling mining.

[0003] Although the existing solid waste cementing filling material mixing device can efficiently mix the filling material, since the powdered cementing material will float on the liquid surface for a period of time after continuously entering the mixing tank and is difficult to melt, the slurry splashes caused by the stirring of the stirring blades in the mixing tank, which not only causes serious material agglomeration on the upper part of the mixing tank and blocks the feed port, affecting production, but also the raw materials at the bottom of the tank cannot be fully stirred, reducing the stirring and mixing effect. At the same time, after the mixing device has been working for a period of time, it is inevitable that there will be agglomerates and the like attached to the side walls of the mixing tank and the stirring blades. If they are not cleaned regularly, the operating burden of the equipment will increase and the mixing efficiency will be reduced. In the existing mixing device, since the stirring structure is all located in the mixing tank, and the stirring result is often connected to the motor on the top of the mixing tank, the disassembly operation is relatively cumbersome and difficult, which is not conducive to regular maintenance and cleaning of the mixing device.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Embodiment 1:

[0031] Reference Figure 1-Figure 6 The present invention provides a device for mixing a mining solid waste cementing filling material, comprising:

[0032] A funnel-shaped tank body 1, the top and bottom of the funnel-shaped tank body 1 are respectively provided with openings, the top of the funnel-shaped tank body 1 is detachably connected with a top plate 2, a feeding assembly is provided in the top opening of the funnel-shaped tank body 1, the feeding assembly is located on one side of the top opening of the funnel-shaped tank body 1, a watering assembly is provided on the feeding assembly, a blocking block 13 is detachably connected in the bottom opening of the funnel-shaped tank body 1, a driving member is provided between the blocking block 13 and the funnel-shaped tank body 1, and the driving member is used to seal the blocking block 13 in the bottom opening of the funnel-shaped tank body 1 or to detach from the bottom opening;

[0033] The stirring assembly includes a stirring rod 7 and a motor 4 arranged on the top plate 2. The motor 4 is detachably connected to the top of the stirring rod 7. A stirring blade assembly and a bottom stirring member are arranged on the stirring rod 7 from top to bottom. A stirring rod support is arranged between the stirring rod 7 and the feeding assembly. The stirring rod support is used to maintain the stirring rod 7 in an upright state when the stirring rod 7 is separated from the motor 4.

[0034] The main function of the feeding assembly is to facilitate the pouring of the preparation materials of the cementing filling material into the funnel-shaped tank body 1; the main function of the watering assembly is to spray the water for stirring into the funnel-shaped tank body 1 during the stirring process, and at the same time, use the impact of water to prevent the feeding assembly from caking; the main function of the block 13 is to block the bottom opening of the funnel-shaped tank body 1, and at the same time, after the mixing is completed, the mixed material is discharged by separating from the bottom opening of the funnel-shaped tank body 1; the main function of the stirring blade assembly is to stir the raw materials; the main function of the bottom stirring piece is to stir the raw materials at the bottom of the funnel-shaped tank body 1 to ensure that the mixing process is fully carried out; the motor 4 and the stirring rod are detachably connected, so that when the top plate 2 is removed from the funnel-shaped tank body 1, the motor 4 and the stirring rod are in a disconnected state, which reduces the difficulty of disassembling the top plate 2; the main function of the stirring rod support is that when the motor 4 and the stirring rod 7 are in a disconnected state, the stirring rod 7 can be in an upright state in the funnel-shaped tank body 1 without falling down, thereby reducing the difficulty of reconnecting the motor 4 and the stirring rod 7 when the top plate 2 is installed. On the whole, the mixing device of the present invention can spray water into the feed assembly during the mixing and stirring process, which not only meets the demand for water in the mixing process, but also can use the impact force of water to avoid clogging of the feed port due to the agglomeration of raw materials; at the same time, by setting the motor and the stirring rod as a detachable connection, it is convenient to remove the top plate, and use the stirring rod support to maintain the stirring rod in an upright state, which is convenient for reconnecting the motor and the stirring rod when the top plate is reinstalled, and is easy to disassemble and clean the inside of the mixing tank; at the same time, by setting a bottom stirring piece to improve the mixing efficiency of the bottom raw materials, insufficient mixing can be effectively avoided.

[0035] A further optimized solution is that the feed assembly includes a feed frame 6, which is horizontally fixedly connected to the side wall of the top opening of the funnel-shaped tank body 1, and the feed frame 6 is connected to the interior of the funnel-shaped tank body 1. A plurality of railings 19 are horizontally fixedly connected to the interior of the feed frame 6, and the plurality of railings 19 are arranged in parallel at equal intervals.

[0036] like Figure 1 and Figure 4 As shown, by setting a plurality of railings 19, larger particulate matter in various raw materials can be filtered to improve the quality of the cementing filling material after mixing. At the same time, the feed frame 6 is fixedly connected to the funnel-shaped tank body 1 and has no connection relationship with the top plate 2, which can provide a stable fixed structure for the setting of the stirring rod support.

[0037] A further optimized solution is that the sprinkler assembly includes an aggregate enclosure 5, which is fixedly connected to the top of the feed frame 6, the aggregate enclosure 5 is communicated with the feed frame 6, and a plurality of second water nozzles 18 are fixedly connected to the side wall of the aggregate enclosure 5, and the plurality of second water nozzles 18 are used to spray water in the direction of the feed frame 6.

[0038] like Figure 1 and Figure 4 As shown, the top opening of the aggregate enclosure 5 is relatively large to prevent accidental spillage when the raw materials are poured in.

[0039] At the same time, the water mist sprayed by the plurality of second water nozzles 18 can prevent dust from floating out of the feed frame 6 during the process of pouring raw materials, thereby improving the environmental friendliness; during the mixing process, water is sprayed onto the feed frame 6 by the plurality of second water nozzles 18, which can provide the required water source for the mixing process, and at the same time, the continuous impact of water can be used to avoid the occurrence of material agglomeration on the feed frame 6 and the railing 19.

[0040] A further optimized solution is that the driving member includes a plurality of hydraulic cylinders 14 vertically fixedly connected to the bottom of the side wall of the funnel-shaped tank body 1, the bottom of the block 13 is located outside the bottom opening of the funnel-shaped tank body 1, and the telescopic ends of the plurality of hydraulic cylinders 14 are fixedly connected to the bottom of the block 13.

[0041] According to a further optimization scheme, a sealing ring 15 is fixedly connected to the inner wall of the bottom opening of the funnel-shaped tank body 1, the inner wall of the sealing ring 15 is provided with an inclined surface, and the top of the side wall of the blocking block 13 is provided with an annular wedge surface, and the wedge surface is adapted to the inclined surface.

[0042] like Figure 1 As shown, during the mixing process, the hydraulic cylinder 14 is in a contracted state. At this time, the block 13 is in a high position, and the annular wedge surface on the top of the block 13 fits tightly with the inclined surface on the inner side of the sealing ring 15, thereby achieving the purpose of sealing the bottom opening of the funnel-shaped tank body 1.

[0043] When the mixing is completed and the cementitious filling material needs to be discharged from the funnel-shaped tank body 1, the hydraulic cylinder 14 can extend the telescopic end to make the block 13 drop to below the bottom opening of the funnel-shaped tank body 1. At this time, the cementitious filling material can flow out from the bottom opening of the funnel-shaped tank body 1, and the annular wedge surface on the side wall of the block 13 can guide the flow of the cementitious filling material to avoid excessive cementitious filling material from accumulating on the top of the block 13.

[0044] According to a further optimized solution, the bottom of the sealing ring 15 and the bottom of the bottom opening of the funnel-shaped tank body 1 are respectively fixedly connected with a plurality of first water spray nozzles 16;

[0045] The first water nozzles 16 at the bottom of the sealing ring 15 are used to spray water onto the inner wall of the bottom opening of the funnel-shaped tank body 1. When the block 13 is driven by the hydraulic cylinder 14 to move downwardly away from the bottom opening of the funnel-shaped tank body 1, the first water nozzles 16 located at the bottom of the bottom opening of the funnel-shaped tank body 1 are used to spray water onto the surface of the block 13.

[0046] like Figure 1 As shown, after the cementing filling material is led out, the block 13 needs to be raised again to fit with the sealing ring 15. Before the raising, a plurality of first water nozzles 16 are controlled to spray water. The water sprayed by the first water nozzle 16 located at the bottom of the sealing ring 15 flushes the inner wall of the bottom opening of the funnel-shaped tank body 1, and the attached cementing filling material is completely flushed down. The water sprayed by the first water nozzle 16 located at the bottom of the bottom opening of the funnel-shaped tank body 1 can flush the top and side walls of the block 13. After flushing, the block 13 and the filling material attached to the bottom opening of the funnel-shaped tank body 1 can be effectively prevented from affecting the blocking effect of the block 13.

[0047] In a further optimized solution, a lifting assembly is provided between the motor 4 and the top plate 2, and the lifting assembly is used to raise or lower the height of the motor 4;

[0048] The lifting assembly includes two groups of support rods 23 vertically fixedly connected to the top of the top plate 2, two groups of connecting blocks 24 are fixedly connected to the side walls of the motor 4, the two connecting blocks 24 are respectively slidably connected in the two support rods 23, and a lifting drive member is arranged between the connecting block 24 and the support rod 23. A support block 27 is also fixedly connected to the support rod 23, and a detachable connection is achieved between the support block 27 and the connecting block 24 by a fixing bolt 28.

[0049] When in working state, the connection block 24 and the support block 27 can be fixedly connected by fixing bolts 28 to prevent the motor 4 from shaking during operation and improve the operation stability of the equipment.

[0050] According to a further optimized solution, the lifting drive member includes a screw rod 25 vertically rotatably connected to the support rod 23, the screw rod 25 is transmission-connected to the connecting block 24, and the top of the screw rod 25 passes through the top of the support rod 23 and is fixedly connected to a rotating wheel 26.

[0051] According to a further optimization scheme, a through hole 17 is provided in the center of the top plate 2, the top of the stirring rod 7 passes through the through hole 17, a shaft sleeve 29 is fixedly connected to the output shaft of the motor 4, and the top of the stirring rod 7 is detachably connected to the output shaft of the motor 4 through the shaft sleeve 29.

[0052] According to a further optimized solution, a bolt 30 is horizontally arranged in the shaft sleeve 29 , and the bolt 30 passes through the top end of the stirring rod 7 , and its main function is to fix the stirring rod 7 in the shaft sleeve 29 .

[0053] like Figure 1and Figure 2 As shown, when the top plate 2 needs to be disassembled, the motor 4 needs to be disconnected from the stirring rod 7 first. Specifically, by unscrewing the bolt 30, only a sliding connection exists between the stirring rod 7 and the sleeve 29. Then, the rotating wheel 26 is rotated to drive the screw rod 25 to rotate. The threaded transmission between the screw rod 25 and the connecting block 24 is used to make the connecting block 24 rise, thereby driving the motor 4 to rise, so that the sleeve 29 and the stirring rod 7 are disconnected. At this time, the top plate 2 can be easily removed from the top of the funnel-shaped tank body 1.

[0054] A further optimized solution is that the stirring rod support includes a support rod 21 horizontally fixedly connected to the side wall of the feed frame 6, and one end of the support rod 21 away from the feed frame 6 is fixedly connected with a semicircular ring 22, which is arranged close to the through hole 17 and corresponds to the stirring rod 7.

[0055] like Figure 2 and Figure 6 As shown, after the stirring rod 7 is disconnected from the shaft sleeve 29, the stirring rod 7 can be controlled to slightly fall down into the semicircular ring 22, and the stirring rod 7 can be maintained in a nearly upright state by the support function of the semicircular ring 22. The length of the support rod 21 needs to ensure that the stirring rod 7 can be supported by the semicircular ring 22 before the top plate 2 is removed and the stirring rod 7 contacts the side wall of the through hole 17.

[0056] According to a further optimized solution, a socket 32 ​​is vertically opened at the top of the blocking block 13 , and a rotating disk 31 is rotatably connected to the bottom of the socket 32 ​​. The bottom of the stirring rod 7 is inserted into the socket 32 ​​and abuts against the rotating disk 31 .

[0057] like Figure 1 and Figure 3 As shown, when the stirring rod 7 is separated from the shaft sleeve 29 , the stirring rod 7 can be supported in the funnel-shaped tank body 1 by the blocking block 13 .

[0058] The main function of the rotating disk 31 is to reduce the friction between the stirring rod 7 and the bottom of the insertion hole 32 when the stirring rod 7 accidentally contacts the bottom of the insertion hole 32 during the mixing process.

[0059] To further optimize the solution, a water injection port 3 is opened on the top plate 2 to assist in injecting water into the funnel-shaped tank body 1 .

[0060] Further optimization scheme, such as Figure 5 As shown, an opening 20 is provided on one side of the top plate 2 , and the size of the opening 20 matches the size of the feed frame 6 , so as to facilitate the installation and rotation of the top plate 2 and the funnel-shaped tank body 1 .

[0061] According to a further optimization scheme, the top plate 2 and the top of the funnel-shaped tank body 1 can be fixedly connected by setting fastening bolts.

[0062] The working process of this embodiment is as follows: the raw materials required for mixing are poured into the funnel-shaped tank body 1 through the feed frame 6. Afterwards, the motor 4 drives the stirring blade assembly and the bottom stirring assembly through the stirring rod 7 to stir the raw materials in the funnel-shaped tank body 1. During the stirring process, the required water is sprayed into the funnel-shaped tank body 1 through the second water spray nozzle 18. After the mixing is completed, the block 13 is moved down to the bottom of the bottom opening of the funnel-shaped tank body 1 through the hydraulic cylinder 14 to allow the cementing filling material to be discharged. After the discharge is completed, the block and the bottom opening of the funnel-shaped tank body 1 are flushed through the first water spray nozzle 16, and the block 13 is raised back to the blocking position.

[0063] When it is necessary to clean the inside of the mixing device, the operator first unscrews the bolt 30 and the fixing bolt 28, and then rotates the wheel 26 to lift the motor 4. At this time, the stirring rod 7 is separated from the sleeve 29, and the stirring rod 7 is held by hand to make it contact with the semicircular ring 22. After that, the top plate 2 can be easily removed by disassembling the top plate 2. At this time, the bottom of the stirring rod 7 is in contact with the rotating disk 31. If necessary, the stirring rod 7 can also be taken out of the funnel-shaped tank body 1. After cleaning, the stirring rod 7 is put back into the funnel-shaped tank body 1 and abuts on the rotating disk 31, the top plate 2 is installed, and it is ensured that the top of the stirring rod 7 passes through the through hole 17. After that, the wheel 26 is rotated, the motor 4 is lowered, the sleeve 29 is re-connected with the stirring rod 7, and the bolt 30 and the fixing bolt 28 are connected.

[0064] Embodiment 2:

[0065] The stirring blade assembly includes an auger stirring blade 10 fixedly connected to the stirring rod 7 and a plurality of side stirring rods 8. The plurality of side stirring rods 8 are arranged close to the side wall of the funnel-shaped tank body 1 and parallel to the side wall of the funnel-shaped tank body 1. The top and bottom of the side stirring rods 8 are respectively arranged close to the top and bottom of the funnel-shaped tank body 1. The plurality of side stirring rods 8 are evenly distributed in the funnel-shaped tank body 1 and are fixedly connected to the stirring rod 7 through a connecting rod 9.

[0066] like Figure 1 As shown, when the stirring rod 7 is driven by the motor 4 to rotate, the auger stirring blade 10 can stir and tumble the raw materials upward, and the side stirring rod 8 can stir the raw materials close to the side wall of the funnel-shaped tank body 1 and transfer the raw materials to the bottom of the auger stirring blade 10, thereby achieving efficient stirring.

[0067] Embodiment three:

[0068] The bottom stirring member includes two groups of bottom stirring blades 11, and the two groups of bottom stirring blades 11 are respectively arranged at the positions of the stirring rod 7 close to the block 13, and the two groups of bottom stirring blades 11 are arranged from top to bottom, and the edges of the two groups of bottom stirring blades 11 are respectively tilted and fixedly connected with a plurality of inclined stirring rods 12, and the plurality of inclined stirring rods 12 on the bottom stirring blade 11 located at the top are tilted upward, and the plurality of inclined stirring rods 12 on the bottom stirring blade 11 located at the bottom are tilted downward.

[0069] like Figure 1 As shown, a plurality of inclined stirring rods 12 can stir the raw materials at the bottom of the funnel-shaped tank body 1 .
