Description

Technical Field

[0001] This utility model relates to the field of mineral processing mixing, and in particular to a slurry mixing tank for mineral processing. Background Technology

[0002] The mineral processing slurry mixing tank is a pretreatment equipment with mixing as its core function. It generates strong shear force and circulating flow field through the high-speed rotation of the impeller, so that the mineral particles are fully suspended and dispersed in the slurry. At the same time, it rapidly and evenly mixes the collectors, modifiers and other agents into the slurry and allows them to fully interact with the mineral surface.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN221015749U, a slurry mixing tank for mineral processing is disclosed. It is designed to crush large particles into powder by grinding blocks to achieve slurry mixing. However, in actual use, it has been found that although such equipment can process particulate matter in a timely manner, the particulate matter is returned to the original slurry by spiral extrusion and gravity during processing. However, the overall mixing power of the equipment comes from the central mixing blade. There is no suitable mixing structure between the outer and inner walls, which makes it impossible to form a reasonable internal circulation. As a result, the high and low concentration slurries cannot be mixed and stirred in a timely manner. The high concentration slurry tends to settle at the bottom, affecting the quality of the finished product. Utility Model Content

[0004] The purpose of this invention is to provide a slurry mixing tank for mineral processing in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A slurry mixing tank for mineral processing includes a mixing tank body for providing mixing space and a power mechanism for providing mixing power. The power mechanism is mounted on the upper end of the mixing tank body via a crossbeam. A support is connected to the outside of the mixing tank body. The tank body also includes an external mixing mechanism for providing mixing, a pulse mechanism for increasing internal turbulence, and an internal mixing mechanism. The internal mixing mechanism is installed at the axial position inside the mixing tank body. The external mixing mechanism is rotatably connected to the outside of the internal mixing mechanism. The pulse mechanism is located at the bottom inside the internal mixing mechanism.

[0007] The bottom of the main shaft of the external stirring mechanism is fixedly connected to a spiral blade, and the bottom of the spiral blade is provided with a bottom inclined blade;

[0008] The top of the central cylinder of the internal stirring mechanism is connected to a cross frame by bolts. The top of the central cylinder has a feed inlet for raw material return. The extrusion spiral blades are rotatably connected inside the central cylinder. The injection pipe of the pulse mechanism is arranged around the lower side of the central cylinder.

[0009] Preferably, the main shaft passes through the central cylinder from top to bottom and drives the extrusion spiral blade to rotate. The central cylinder includes a hollow section, an extrusion section, and a pressurization section. The extrusion spiral blade is provided with a friction plate on the outer side of the extrusion section, and the friction plate is in frictional engagement with the inner wall of the central cylinder.

[0010] Preferably, the pulse mechanism includes a jet tube and a pulse disk. The pulse disk is slidably connected to the bottom of the inner side of the central cylinder. The top of the pulse disk cooperates with the main shaft through a reciprocating assembly. A reset member is provided between the bottom of the pulse disk and the central cylinder. Four jet tubes are provided and evenly arranged in an array on the outside of the central cylinder. The jet tubes are in communication with the internal space of the central cylinder.

[0011] Preferably, the injection pipe includes an upper injection pipe and a lower injection pipe, which are staggered, and the inlet of the injection pipe is located at the upper end of the highest horizontal plane of the pulse disk.

[0012] Preferably, the reciprocating assembly includes an extrusion plate, an extrusion groove, and an extrusion rod. The extrusion plate is fixed to the top of the pulse disk, and the extrusion rod is a shaft that is laterally connected to the main shaft. The extrusion plate is formed with an extrusion groove that cooperates with the extrusion rod to perform extrusion lifting.

[0013] Preferably, the central cylinder extrusion section has a conical structure, the angle between the friction plate and the horizontal plane is greater than the angle between the extrusion section and the water surface, and the friction plate has rounded corners corresponding to the rotation direction.

[0014] Preferably, the injection pipe has an arc-shaped structure and a flat cross-section.

[0015] Compared with existing technologies, the beneficial effects are as follows:

[0016] During the mixing process, particles and part of the slurry are recovered through the central position, and then processed and sprayed through the internal mixing mechanism and pulse mechanism. This provides multi-dimensional turbulence to the bottom mixing space, thereby improving the mixing effect, ensuring the quality of the finished slurry, and reducing processing time.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8 As shown, a slurry mixing tank for mineral processing includes a mixing tank body 3 for providing mixing space and a power mechanism 2 for providing mixing power. The power mechanism 2 is mounted on the upper end of the mixing tank body 3 via a cross frame. A support 1 is connected to the outside of the mixing tank body 3. It also includes an outer mixing mechanism 4 for providing mixing, a pulse mechanism 6 for improving internal turbulence, and an inner mixing mechanism 5. The inner mixing mechanism 5 is installed at the axial position inside the mixing tank body 3. The outer mixing mechanism 4 is rotatably connected to the outside of the inner mixing mechanism 5. The pulse mechanism 6 is located at the bottom inside the inner mixing mechanism 5.

[0031] The bottom of the main shaft 41 of the external stirring mechanism 4 is fixedly connected to a spiral blade 42, and the bottom of the spiral blade 42 is provided with a bottom inclined blade 43;

[0032] The top of the central cylinder 51 of the internal stirring mechanism 5 is connected to a cross frame by bolts. The top of the central cylinder 51 has a feed inlet 52 for raw material return. The extrusion spiral blade 53 is rotatably connected inside the central cylinder 51. The injection pipe 61 of the pulse mechanism 6 is arranged around the lower side of the central cylinder 51.

[0033] In this embodiment, the main shaft 41 passes through the central cylinder 51 from top to bottom and drives the extrusion spiral blade 53 to rotate. The central cylinder 51 includes a hollow section, an extrusion section, and a pressurization section. The extrusion spiral blade 53 is provided with a friction plate 54 on the outer side of the extrusion section. The friction plate 54 is in frictional engagement with the inner wall of the central cylinder 51.

[0034] In this embodiment, the pulse mechanism 6 includes a jet pipe 61 and a pulse disk 62. The pulse disk 62 is slidably connected to the bottom of the inner side of the central cylinder 51. The top of the pulse disk 62 is connected to the main shaft 41 through a reciprocating assembly 63. A reset member 64 is provided between the bottom of the pulse disk 62 and the central cylinder 51. Four jet pipes 61 are provided and evenly arranged on the outside of the central cylinder 51. The jet pipes 61 and the internal space of the central cylinder 51 are connected. The jet pipe 61 includes an upper jet pipe and a lower jet pipe, which are staggered. The inlet of the jet pipe 61 is located at the upper end of the highest horizontal surface of the pulse disk 62. The jet pipe 61 has a semi-arc structure and a flat cross-section. By using the flat and bent jet pipe 61, the jet direction can be improved and the multi-dimensional effect of the jet can be enhanced.

[0035] In this embodiment, the reciprocating assembly 63 includes an extrusion plate 631, an extrusion groove 632, and an extrusion rod 633. The extrusion plate 631 is fixed to the top of the pulse disk 62, and the extrusion rod 633 is a shaft horizontally connected to the main shaft 41. The extrusion plate 631 has an extrusion groove 632 formed on it to cooperate with the extrusion rod 633 for extrusion and lifting. When the main shaft 41 drives the extrusion rod 633 to rotate, the extrusion rod 633 cooperates with the extrusion plate 631 through the extrusion groove 632 to extrude, causing the pulse disk 62 to sink until it reaches the release position. Then, the pulse disk 62 quickly resets under the support of the spring of the reset component 64, thereby pushing the slurry at the bottom upwards quickly. Simultaneously, the slurry pressed down by the extrusion spiral blade 53 is released from the surrounding injection pipes 61. After multiple cycles, a pulse is formed, thereby spraying the slurry in the central area to the bottom and surrounding areas, increasing the turbulence of the slurry in the bottom space.

[0036] In this embodiment, the extrusion section of the central cylinder 51 has a conical structure. The angle between the friction plate 54 and the horizontal plane is greater than the angle between the extrusion section and the water surface. The friction plate 54 has rounded corners corresponding to the rotation direction. The friction plate 54 also rotates under the drive of the main shaft 41. Some large particles will cooperate with the friction plate 54 in the extrusion section of the central cylinder 51, thereby grinding the particles. Figure 6 As shown, as the space gradually decreases, the particles will gradually grind and become smaller.

[0037] Working principle: Start the motor of the top power mechanism 2, and drive the main shaft 41 to rotate through the reducer and coupling. After the main shaft 41 rotates, the bottom spiral blade 42 and the bottom inclined blade 43 will be driven to rotate synchronously, thereby stirring the slurry inside the mixing tank 3. At this time, the stirring dynamic of the slurry in the internal space is shown by the dotted line part in the mixing tank 3 in the figure.

[0038] Similarly, the extrusion spiral blades 53, friction plates 54 and the bottom extrusion rods 633 inside the central cylinder 51 are driven to rotate. The external slurry flows into the central cylinder 51 through the feed inlet 52 at the top of the central cylinder 51. In the mixing equipment in the mining industry, large particles tend to accumulate in the central area under the mixing environment. At this time, the large particles are also brought into the central cylinder 51 at the same time.

[0039] The slurry and large particles sink into the central cylinder 51. First, they are subjected to extrusion friction between the friction plates 54 and the inner wall of the central cylinder 51, which grinds the particles. Simultaneously, the friction plates 54 mix and stir the particles. Then, the extrusion spiral blades 53 further extrude and stir the particles. Simultaneously, the rotating extrusion rod 633 also extrudes the extrusion groove 632 and the extrusion plate 631, causing the pulse disk 62 to sink. When the extrusion rod 633 reaches the release position of the extrusion groove 632, the pulse disk 62 quickly resets under the support of the reset member 64. The downward pressure of the slurry driven by the extrusion spiral blades 53 at the top, combined with the reset pressure of the pulse disk 62 at the top, creates a... Figures 8 to 7The change is that only four injection pipes 61 serve as release ports, thereby driving the slurry to be ejected from the four injection pipes 61 positions, breaking the original steady-state mixing, thereby increasing internal turbulence and improving the mixing effect.
