Description

Technical Field

[0001] The present application relates to the technical field of mine filling, and specifically discloses a stirring device for filling mine pits with paste made of all-tailings sand. Background Art

[0002] Tailings sand is the waste discharged by a concentrator after grinding ore and selecting useful components under specific economic and technical conditions. 2. It is generally a solid mineral waste formed by natural dehydration of the tailings pulp discharged by the concentrator. It is the main component of solid industrial waste and can be regarded as a composite mineral material such as silicate carbonate. The content of the main useful components in the tailings is called the tailings grade. 3. It is generally a solid mineral waste formed by natural dehydration of the tailings pulp discharged by the concentrator and is the main component of solid industrial waste. 4. The slag remaining after the extraction of the original ore during the mining process;

[0003] Regarding mine pits: the pits and tunnels excavated for mining need to be filled back after mining;

[0004] Currently, the materials used for filling back usually adopt a mixture of tailings sand and cement, and an automatic filling device such as a spraying machine is used to fill back the mine pits;

[0005] In order to improve the filling effect, the tailings sand and cement are fully stirred to form a mixture. The current problem is that the size of some tailings sand is too different from the size of cement ash, resulting in the inability to stir and mix the tailings sand and cement, and thus the poor effect of the formed mixture. In view of this, the inventor proposes a stirring device for filling mine pits with paste made of all-tailings sand. Utility Model Content

[0006] The purpose of the present utility model is to solve the problem that the traditional stirring device cannot handle the situation where the size of tailings sand is too different from the size of cement ash.

[0007] In order to achieve the above purpose, the present utility model provides the following basic solution:

[0008] A stirring device for filling mine pits with paste made of all-tailings sand, comprising a cylinder body, a discharge port provided at the bottom of the cylinder body, an end cover detachably connected to the cylinder body, a connecting block located at the connection between the cylinder body and the end cover, a motor provided on the top of the end cover, a first feed pipe detachably connected to the end cover, and a plurality of second feed pipes provided on the end cover. The connecting block forms a working groove with the end cover and the cylinder body. The second feed pipes penetrate through the inner wall of the end cover, pass through the working groove, and penetrate out from the inside of the bottom of the cylinder body. The output end of the motor is provided with a rotating disk capable of squeezing the second feed pipes and a plurality of stirring rods for stirring.

[0009] The principle and effect of this basic solution are as follows:

[0010] 1. Compared with the prior art, the present device has a simple structure and an ingenious design. The present device is provided with a first feed pipe, a second feed pipe and a discharge pipe, which reasonably and clearly define the different input positions of different raw materials. The first feed pipe and the second feed pipe do not interfere with each other, and the discharge pipe is arranged at the bottom of the cylinder, which is convenient for the rapid outflow of the stirred mixed material. In addition, a discharge pipe is provided, and the discharge pipe is also convenient for connecting an output component with a pump, so that the stirred mixed material can quickly fill the pit.

[0011] 2. Compared with the prior art, the present device adopts a design mode of detachable connection between the cylinder and the end cover, and a connecting block is designed based on the detachable connection design mode, so that the connecting block, the end cover and the cylinder form a working groove, and a part of the second feed pipe is arranged in the working groove, so that the rotating disk can be squeezed to the second feed pipe located in the working groove. After being squeezed to the second feed pipe located in the working groove, the raw material located in the second feed pipe is further refined, making the size closer to cement ash, thereby solving the problem that the traditional stirring device cannot handle the large difference between the size of tailings sand and the size of cement ash.

[0012] 3. Compared with the prior art, in order to better achieve the extrusion effect of the rotating disk, this case sets a motor as a driving component. The circular rotation of the motor output shaft can better achieve the extrusion effect of the rotating disk. In addition, based on the rotation of the motor, a stirring rod is designed so that the stirring rod can rotate, which is beneficial to the mixing of raw materials, thereby improving the mixing effect and facilitating the full mixing of cement ash and tailings sand.

[0013] 4. Compared with the prior art, the device is simple to install, easy to maintain and easy to replace. The device adopts a vertical structure and a screwless insertion connection method, that is, the connecting block is inserted into the surface of the cylinder, which realizes the rapid installation and rapid disassembly of the end cover and the cylinder.

[0014] 5. Compared with the prior art, the device adopts a quick installation method for the end cover and the cylinder, that is, water can be injected into the cylinder first, and then the mixing process can be realized. The advantage is that when the water is injected, no raw materials are put in, that is, there is no problem of accurate formula ratio due to the impact of water on the raw materials causing the raw materials to fly up and stick to the wall.

[0015] Furthermore, a switch valve is provided on the discharge port, and a plurality of support columns are provided at the bottom of the cylinder, and the free ends of the support columns are fixedly connected with rubber anti-slip pads.

[0016] Furthermore, an annular groove is formed on the upper end surface of the cylinder, and the lower end surface of the end cover is used for fixing the connecting block, into which the connecting block is inserted, and the connecting block is arranged on the outer side of the lower end surface of the end cover.

[0017] Further, through grooves with the same number as the second feed pipes are formed in the inner side of the lower end face of the end cover and the upper end face of the cylinder body. The second feed pipes are inserted into the through grooves. An opening is provided on one side of the through groove located at the bottom of the cylinder body facing the center of the cylinder body, and a material guide plate is arranged at the opening position.

[0018] Further, the second feed pipe includes an elastic hose and rigid pipes connected to both ends of the elastic hose. The rigid pipes are respectively placed in the inner walls of the end cover and the cylinder body, and the elastic hose is arranged in the working groove.

[0019] Further, the rigid pipe located in the inner wall of the end cover is threadedly connected to the end cover, and the rigid pipe passes through the end cover upward and is provided with a collecting plate. The collecting plate is provided with connecting holes corresponding to the rigid pipes in number and position one by one. The inner bottom surfaces of the collecting plate facing the connecting holes are all inclined surfaces, and the inclined surfaces are all inclined towards the center of the connecting holes.

[0020] Further, a connecting shaft is provided at the output end of the motor. The connecting shaft passes through the end cover and is coaxially connected to the rotating disk. The rotating disk and the working groove are in the same plane, and extrusion teeth are evenly distributed on the outer circumference of the rotating disk.

[0021] Further, an extension shaft is coaxially connected to one side of the rotating disk facing the cylinder body, and the stirring rods are evenly fixed around the extension shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, elaborate in detail on the specific implementation manner, structure, features and their effects of the present utility model as follows.

[0028] The reference numerals in the accompanying drawings of the specification include: cylindrical body 1, support column 2, rubber anti-slip pad 3, annular groove 4, connection block 5, end cover 6, second feed pipe 7, hard pipe 701, elastic hose 702, first feed pipe 8, connection hole 9, special hole 10, collection plate 11, motor 12, connection shaft 13, rotating disk 14, extrusion teeth 1401, extension shaft 15, stirring rod 16, and material guiding plate 17.

[0029] The embodiments are as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown:

[0030] A stirring device for filling a whole-tailings paste mine pit, comprising a cylindrical body 1, a discharge port provided at the bottom of the cylindrical body 1, an end cover 6 detachably connected to the cylindrical body 1, a connection block 5 located at the connection between the cylindrical body 1 and the end cover 6, a motor 12 provided on the top of the end cover 6, a first feed pipe 8 detachably connected to the end cover 6, and a plurality of second feed pipes 7 provided on the end cover 6. The connection block 5 and the end cover 6 and the cylindrical body 1 form a working groove. The second feed pipe 7 penetrates through the inner wall of the end cover 6, passes through the working groove, and penetrates out from the inside of the bottom of the cylindrical body 1. The output end of the motor 12 is provided with a rotating disk 14 capable of extruding the second feed pipe 7 and a plurality of stirring rods 16 for stirring.

[0031] As Figure 1 shown, both the cylindrical body 1 and the end cover 6 adopt a non-angular cylindrical structure to improve the safety of the device. A switch valve is provided on the discharge port, and the switch valve is a mechanical ball valve for the mixture to flow out from the discharge port. A plurality of support columns 2 are further provided at the bottom of the cylindrical body 1, and the free ends of the support columns 2 are fixedly connected with rubber anti-slip pads 3 to achieve the vertical prevention of the device and improve the stability of the device.

[0032] As Figure 1 and Figure 2 and Figure 3 shown, an annular groove 4 is opened on the upper end surface of the cylindrical body 1, and the lower end surface of the end cover 6 is used for the fixation of the connection block 5. The connection block 5 is inserted into the connection block 5. Specifically: the connection block 5 is provided on the outside of the lower end surface of the end cover 6, through grooves with the same number as the second feed pipes 7 are opened on the inner side of the lower end surface of the end cover 6 and the upper end surface of the cylindrical body 1, and the second feed pipes 7 are inserted into the through grooves. An opening is provided on one side of the through groove at the bottom of the cylindrical body 1 facing the center of the cylindrical body 1, and a material guiding plate 17 is provided at the opening position.

[0033] Specifically, the second feed pipe 7 includes an elastic hose 702 and rigid pipes 701 connected to both ends of the elastic hose 702. The rigid pipes 701 are respectively placed in the inner walls of the end cap 6 and the cylinder body 1. The elastic hose 702 is arranged in the working groove. The rigid pipe 701 located in the inner wall of the end cap 6 is threadedly connected to the end cap 6, and the rigid pipe 701 passes upward through the end cap 6 and is provided with an assembly tray 11. The assembly tray 11 is provided with connection holes 9 corresponding to the rigid pipes 701 in number and position one by one. The inner bottom surfaces of the assembly tray 11 facing the connection holes 9 are all inclined surfaces, and the inclined surfaces are all inclined towards the center of the connection holes 9.

[0034] Specifically:

[0035] In terms of installation, the second feed pipe 7 is inserted into the end cap 6 and the cylinder body 1 based on the design of the through groove. Since the end cap 6 and the cylinder body 1 are installed based on the design of the connection block 5, as Figure 2 shown, at the installation position of the connection block 5, the second feed pipe 7 will be exposed. Since the second feed pipe 7 includes an elastic hose 702, the elastic hose 702 is arranged in the working groove. The advantage of this design is that the rigid pipe 701 part strengthens the connection stability of the second feed pipe 7, and the elastic hose 702 receives the extrusion brought by the rotation of the rotating disk 14.

[0036] As Figure 2 and Figure 4 shown, the output end of the motor 12 is provided with a connecting shaft 13. The connecting shaft 13 passes through the end cap 6 and is coaxially connected to the rotating disk 14. The rotating disk 14 and the working groove are in the same plane. The outer periphery of the rotating disk 14 is evenly distributed with extrusion teeth 1401. The elastic hose 702 is extruded through the extrusion teeth 1401. The rotating disk 14 is coaxially connected with an extension shaft 15 towards the lower side of the cylinder body 1. The stirring rods 16 are evenly fixed around the extension shaft 15.

[0037] Specific implementation process:

[0038] The first step is to inject water in a certain proportion into the cylinder body 1 according to the relevant formula ratio before the cylinder body 1 and the end cap 6 are installed. Then, as Figure 1 and Figure 2 shown, install the end cap 6 to connect the end cap 6 and the cylinder body 1. After the end cap 6 is installed, install the second feed pipe 7. After the second feed pipe 7 is installed, install the assembly tray 11. The assembly tray 11 is clamped with the top of the second feed pipe 7, and reasonable waterproof measures are set at the clamping position;

[0039] The second step is to then install the first feed pipe 8. There is a special hole 10 on the end cap 6, and the first feed pipe 8 is threadedly connected to the special hole 10.

[0040] In the third step, start the motor 12. After the motor 12 starts, the first feed pipe 8 feeds a certain proportion of cement ash into the collection tray 11, and a certain proportion of tailings sand is fed into the collection tray 11. For the cement ash, it directly falls inside the cylinder 1 through the end cover 6 and is stirred by the stirring rod 16. For the tailings sand, when it flows into the inside of the cylinder 1 through the second feed pipe 7, it will be extruded by the extrusion disc, making the tailings sand finer and the size of the tailings sand closer to the size of the cement ash. When the sizes of the two are relatively close, they are stirred and mixed by the stirring rod 16 and, under the action of water, are mixed more fully, and the effect naturally becomes better.

[0041] This device solves the problem that the traditional stirring device cannot handle the large difference in size between tailings sand and cement ash.

[0042] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
