Description

Technical Field

[0001] The present application relates to the technical field of continuous stirring and mixing of tailings or gangue, and in particular to a continuous mixing device for filling slurry. Background Art

[0002] In the mining field, the large-scale stacking of coal gangue not only occupies land and affects the ecological environment, but also pollutes the surrounding soil and groundwater with gangue leaching water. In addition, the coal gangue contains certain combustibles, which will spontaneously combust under suitable conditions, emitting harmful gases such as sulfur dioxide, nitrogen oxides, carbon oxides and smoke, polluting the atmospheric environment and affecting the health of residents in the mining area. Coal mining activities leave a large number of goafs. If they are not handled in time, the scale of the goafs will become larger and larger, causing the roof rock layer of the goaf to suddenly collapse, which will not only endanger the safety of underground operations, but also cause the movement and deformation of the overburden layer and even the surface layer. In severe cases, it will lead to major geological disasters such as surface collapse and ground fissures, causing serious damage to surface buildings.

[0003] Backfill mining is a green mining method that prevents surface subsidence from the source, achieves the acquisition of mineral resources with minimal ecological disturbance, and limits the impact on the ecological environment, water and soil resources and infrastructure to the minimum.

Therefore, the underground gangue is not filled in the mine. According to the situation in the mine, the development of integrated, miniaturized, intelligent and mobile gangue slurry mixing equipment can not only improve the ecological environment, but also has broad market application prospects and practical engineering significance.

[0005] In view of the existing filling methods, it is hoped to provide a continuous mixing device for filling slurry, so as to realize integrated and intelligent filling of the slurry. Utility Model Content

[0040] The continuous mixing device for filling slurry of the utility model is a device for preparing filling slurry by stirring and mixing liquid and solid materials, and is generally connected to a pumping device to pump the prepared filling slurry to the use site. Figure 1As shown, a continuous mixing device for filling slurry of an embodiment of the utility model includes a solid material conveying device 1, a liquid conveying device 2, a mixing device 3 and a discharge circulation device 5. In addition, the continuous mixing device for filling slurry of the utility model also includes a skid device 4 and a platform device 6. The solid material conveying device 1 is used to convey solid materials to the mixing device 3, and a belt weighing feeder can be used, wherein a weighing sensor is installed on the belt weighing feeder, and the weight of the conveyed solid material is weighed, and the variable frequency motor can adjust the belt speed to control the conveying amount of the solid material. Depending on the type of solid material being conveyed, multiple solid material conveying devices 1 can be arranged according to demand. In this case, multiple feed ports can be arranged on the mixing device 3 to feed different solid materials. The solid material conveying device 1 can be either a belt weighing feeder or a screw conveyor.

[0041] like Figure 2As shown, the liquid delivery device 2 includes a valve 24 (for example, an electric valve can be preferably used), a first flow meter 25 and a liquid outlet 29, and is used to deliver liquid (for example, water) to the mixing device 3. In addition, the liquid delivery device 2 also includes a main valve 21, a liquid filter 22, a flushing pipe 23, a first valve 26, a second valve 27 and a pipe joint 28. The main valve 21 is responsible for controlling the liquid inlet switch of the liquid manifold, the liquid filter 22 is used to filter impurities in the liquid, and the flushing pipe 23 is equipped with an independent valve. When the liquid is water, the independent valve can be used to flush the equipment and the ground after opening. The valve 24 can control the delivery amount of the liquid to the mixing device 3 by adjusting the valve opening, and the first flow meter 25 can monitor the liquid flow rate, and can cooperate with the valve 24 to realize the real-time control of the delivery amount of the liquid (for example, water). Under normal operating conditions, the first valve 26 is in a closed state, and the second valve 27 is in an open state, which can normally provide liquid, such as clean water, to the mixing device 3. When the second valve 27 is closed and the first valve 26 is opened, liquid, such as clean water, can be provided to other equipment. That is, the first valve 26 is used to control the supply of liquid to other equipment outside the mixing device 3, such as supplying liquid to the outside of the continuous mixing device filled with slurry. Specifically, for example, the first valve 26 can control the delivery of liquid to the pumping device. As described above, the continuous mixing device filled with slurry is generally connected to the pumping device, and specifically the mixing device 3 is directly or indirectly connected to the pumping device to supply the slurry in the mixing device 3 to the pumping device. When the mixing device 3 fails, the liquid (such as clean water) can be directly provided to the pumping device by closing the second valve 27 and opening the first valve 26, and the slurry is replaced with clean water to end the operation. On the other hand, when the pumping device is blocked, the low-pressure suction end of the pumping device can be directly flushed with liquid (such as clean water) to flush the blocked position by closing the second valve 27 and opening the first valve 26. After the blocked position is flushed, normal operation can be continued by closing the first valve 26 and opening the second valve 27. The second valve 27 is used to control the supply of liquid to the mixing device 3. In this way, the liquid delivery device 2 not only has the function of providing liquid (e.g., water supply) to the mixing device 3, but also has the function of providing liquid (e.g., water supply) to other devices other than the mixing device 3, and the ability to provide liquid (e.g., water supply) in multiple directions is realized through a single liquid delivery device 2. The liquid outlet 29 allows the delivered liquid to flow from the liquid delivery device 2 into the mixing device 3. By adjusting the pipe joint 28, the liquid outlet (e.g., water outlet) direction of the liquid outlet 29 can be adjusted, so that the liquid outlet (e.g., water outlet) direction can be adjusted according to the actual operation conditions on site.

[0042] like Figure 3As shown, the mixing device 3 includes a vertical mixing tank body 31, a mixing tank blade and its driving mechanism 33 and a liquid level monitoring device 34, and is used to stir and mix the solid materials and liquid (for example, clean water) transported to the mixing tank to form a slurry. In addition, the mixing device 3 also includes a mixing tank observation window 32, a mixing tank lifting lug 35 and a mixing tank drain outlet 36. The mixing tank body 31 is used to carry the mixed slurry. Through the mixing tank observation window 32, the situation inside the mixing tank can be observed. The mixing tank blade and its driving mechanism 33 are used to stir the slurry in the mixing tank. The liquid level monitoring device 34 monitors the liquid level of the slurry in the mixing tank to ensure that the liquid level fluctuates within a set range. During the equipment manufacturing and assembly process, the hoisting operation is performed through the mixing tank lifting lug 35. When the operation is completed and the mixing tank needs to be emptied or an abnormal situation occurs and the slurry in the tank needs to be discharged urgently, the mixing tank drain outlet 36 is opened to achieve the purpose of emptying the mixing tank. It should be noted that the stirring of the vertical mixing tank 31 can generate strong convection and shear force through the rotation of the blades, so that the materials can be mixed finely. By adjusting the shape and angle of the blades, the movement trajectory and mixing uniformity of the materials can be better controlled.

[0043] The mixing device 3 is not limited to single-stage stirring, and multi-stage stirring can also be used. That is, a mixing tank can be divided into multiple cavities, and the multiple cavities are stirred separately, or multiple mixing tanks can be connected. In addition, a small volume of primary mixing cavity can be arranged above the mixing tank, and after the primary mixing cavity is premixed, the slurry flows into the mixing tank for stirring. In other words, the utility model is not limited to the structure of one stirring tank and one stirring device. In other words, the mixing tank can be provided with multiple cavities for step-by-step stirring or multiple mixing tanks can be connected for step-by-step stirring to achieve a better stirring effect.

[0044] like Figure 4 As shown, the discharge circulation device 5 includes a discharge centrifugal pump 51, a centrifugal pump drive motor 52 and a discharge port 54. The discharge circulation device 5 is connected to the slurry discharge port and the pumping device of the mixing device 3, and is used to discharge the slurry in the mixing device 3 to the pumping device or recirculate it back to the mixing device 3. In addition, the discharge circulation device 5 also includes a sampling port 53, a second flow meter 55, a circulation pipe joint 56, a circulation pipe discharge port 57, a circulation centrifugal pump 58 and a flushing port 59.

[0045] The discharge centrifugal pump 51 is driven by a centrifugal pump drive motor 52 to extract the slurry in the mixing device 3, and the flow rate of the discharged slurry is monitored by a second flow meter 55. In order to confirm the slurry stirring effect, the sampling port 53 can be opened to sample the slurry and confirm the stirring state of the slurry. The discharge port 54 is connected to the pumping device to provide the slurry to the pumping device, that is, to discharge the slurry to the pumping device. The circulation centrifugal pump 58 is driven by another motor and extracts the slurry from the mixing device 3 and discharges it back to the mixing device 3 through the circulation pipe discharge port 57. The direction of the circulation pipe discharge port 57 can be adjusted by adjusting the circulation pipe joint 56 to improve the slurry stirring effect in the mixing tank. The slurry through the circulation pipe discharge port 57 returns to the mixing tank, so that the slurry in the tank forms turbulence, so that the slurry is mixed more fully. When the suction port of the discharge centrifugal pump 51 or the circulation centrifugal pump 58 is blocked or foreign matter appears, the fault of the centrifugal pump suction port can be eliminated by opening the flushing port 59.

[0046] The above describes a technical solution in which a centrifugal pump and a centrifugal pump driving motor are used in the discharge circulation device 5 and the slurry in the mixing device 3 is discharged to the pumping device through the discharge circulation device 5. However, the present invention is not limited thereto. Alternatively, the slurry discharge port of the mixing device 3 can be directly connected to the pumping device, and the continuous mixing device filled with slurry and the pumping device are arranged up and down in space, that is, the mixing device 3 is arranged above the pumping device in the direction of gravity, and the height difference is used to make the slurry automatically supplied to the pumping device by its own flow.

[0047] like Figure 5 As shown, the platform device 6 includes a platform bracket 61, a vertical ladder 62, a guardrail door 63 and a platform grille plate 64. When the operator operates the valve of the discharge circulation device 5 and repairs and maintains the driving device of the mixing device 3, the operator can open the guardrail door 63 and climb onto the platform grille plate 64 through the vertical ladder 62 to perform related operations. The platform grille plate is installed on the platform bracket 61.

[0048] The skid device 4 is used to carry the equipment installed thereon to facilitate the movement or transportation of the equipment. Figure 1 The skid device 4 can be Figure 6 The one-piece type shown, or it can also be a split type.

[0049] like Figure 6As shown, the integrated skid device 4 includes a skid 41, a skid lifting lug 42, a centrifugal pump mounting seat 43 and a motor mounting seat 44. During the assembly or transportation of the whole machine, the equipment is hoisted and transported through the skid lifting lug 42. The centrifugal pump mounting seat 43 is used to install the centrifugal pump 51 of the discharge circulation device 5, and the motor mounting seat 44 is used to install the centrifugal pump drive motor 52 of the discharge circulation device 5. It should be noted that the liquid conveying device 2, the mixing device 3, the discharge circulation device 5 and the platform device 6 are all installed on the skid device 4. The platform device 6 can facilitate the operator to operate the valve of the discharge circulation device 5 and repair and maintain the drive device of the mixing device 3.

[0050] Refer to the following Figures 7 to 10 A continuous mixing device for filling slurry with a split skid device according to another embodiment of the present invention is described.

[0051] and Figure 1 similar, Figure 7 A schematic diagram of a continuous mixing device for filling slurry is shown, which is Figure 1 The only difference is that the skid device 7 included is split, replacing Figure 1 The integrated skid frame device 4 in the embodiment of the present invention has the same structure as the Figure 1 Basically the same.

[0052] Figure 8 It is schematically shown Figure 7 A perspective view of a skid device 7 of a continuous mixing device for filling slurry is shown. Figure 8 As shown, the skid device 7 is split and includes a first skid portion 71 and a second skid portion 73 and a skid connecting device 72 located between the first skid portion 71 and the second skid portion 73. Here, the first skid portion 71 can be a mixing device skid for carrying the liquid conveying device 2 and the mixing device 3, that is, the mixing device 3 and the liquid conveying device 2 are arranged on the first skid portion 71, and the second skid portion 73 can be a discharge circulation device skid for carrying the discharge circulation device 5 and the platform device 6, that is, the discharge circulation device 5 and the platform device 6 are arranged on the second skid portion 73. The skid connecting device 72 is used to detachably connect the first skid portion 71 and the second skid portion 73, that is, the first skid portion 71 and the second skid portion 73 can be connected and detached from each other through the skid connecting device 72. Here, the split skid device 7 also includes a skid hanging ear 42, a centrifugal pump mounting seat 43 and a motor mounting seat 44, wherein the centrifugal pump mounting seat 43 and the motor mounting seat 44 are arranged on the second skid portion 73. Referring to Fig. 9 and Fig.10 It can be seen that the schematic diagram of the continuous mixing device for filling slurry is provided with a split skid device 7, and Figure 7 In comparison, only Figure 7Here, it should be noted that the solid material conveying device 1 is omitted. Fig. 9 and Fig.10 The continuous mixing device for filling slurry shown can be connected with the solid material conveying device 1 at the construction site to form a complete continuous mixing device for filling slurry, and can be transported separately from the solid material conveying device 1 before construction, thereby reducing the volume of the entire transportation equipment to facilitate road transportation. In the case of a split skid frame device 7, before the equipment is installed, the first skid frame part 71 and the second skid frame part 73 can be disassembled by the skid frame connecting device 72 to reduce the size of the entire skid frame device 4, thereby facilitating transportation, and then assembled after being transported to the customer's site of use.

[0053] The operating mechanism of the above structural composition is as follows: the solid material conveying device 1 and the liquid conveying device 2 are used to continuously convey the materials required for stirring to the mixing device 3. The mixing device 3 stirs the slurry. The discharge circulation device 5 is connected to the mixing device 23 and the pumping device, and continuously discharges the stirred slurry to supply the pumping device, and at the same time circulates part of the slurry back to the mixing device 3 for further sufficient stirring.

[0054] According to the scheme of the utility model, the following beneficial effects are achieved: by controlling the delivery amount of solid materials and liquids (such as clean water), the slurry mixing ratio and the material delivery amount are adjusted in real time. The materials are fully mixed and stirred by the mixing device 3 and the discharge circulation device 5, and the slurry is continuously supplied to the pumping equipment through the discharge circulation device. Thereby, the purpose of continuously mixing the slurry and pumping it to the goaf is achieved. The equipment has a high degree of integration and is miniaturized and intelligent. It has broad market application prospects and practical engineering significance. The use of a split skid frame device can further improve the transportation convenience of the equipment, thereby facilitating the installation of the overall equipment.
