Description

Technical Field

[0001] This utility model relates to a mixing device, specifically a laboratory mineral processing mixer. Background Technology

[0002] Mineral processing mixers, also known as mining mixers or slurry mixers, are one of the important auxiliary equipment in the flotation process. Their main function is to mix the ore and reagents before the mineral flotation.

[0003] The mixing tank is a crucial component of a mineral processing mixer, primarily consisting of the tank body and agitator blades installed within it. After material mixing is complete, cleaning of the tank body and agitator blades is generally required, typically involving two steps: detergent cleaning and water rinsing. In existing technologies, the cleaning method for the tank body and agitator blades generally involves the operator first spraying detergent (such as foam detergent) onto the inner wall of the tank and the agitator blades from a detergent bottle. Then, water is injected into the tank, causing the blades to rotate and be washed by the water. Finally, the cleaning water is drained to complete the cleaning process.

[0004] The main drawbacks of this method are: First, manual operation makes it difficult to meet standardized management requirements. In practice, it has been found that the amount of detergent sprayed is often too inaccurate, resulting in poor washing effect or detergent waste. Second, detergent spraying is usually completed in a short time, and the rotation of the stirring blades is relied upon for a longer period of time. It is difficult to ensure that detergent is continuously added for a long time. During the rotation of the blades, most of the detergent is thrown off the blades, resulting in poor cleaning effect. Third, the detergent spraying pressure is low, which affects the washing effect. Fourth, after rinsing with water, the inner wall of the cylinder and the stirring blades still contain moisture. In a small-batch laboratory environment, this water will inevitably affect the accuracy of subsequent experiments, especially the accuracy of moisture measurement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a laboratory mineral processing mixer. First, by improving the detergent addition method, the quantitative control of detergent spraying is realized, and the detergent is continuously added under high pressure for a long period of time, thereby further improving the cleaning effect. Second, after cleaning, the inner wall of the cylinder and the stirring blades are kept dry.

[0006] The technical solution of this utility model is as follows:

[0007] A laboratory mineral processing mixer includes a cylindrical body with an internal stirring shaft and blades. A first motor for driving the stirring shaft to rotate is fixedly installed at the bottom of the cylindrical body. A hopper is connected to the lower end of the cylindrical body. A shaft seat is installed on the outer wall of the cylindrical body, and a rotating frame capable of rotating around the cylindrical body is installed on the outer side of the shaft seat. The mineral processing mixer also includes a mixer connected to the rotating frame via a connecting mechanism. A horizontally arranged nozzle located above the cylindrical body is connected to the lower end of the mixer. The nozzle is equipped with a downward nozzle and an angled nozzle. The mineral processing mixer also includes a rotary drive mechanism for driving the rotating frame to rotate around the cylindrical body. A cleaning agent filling pipe, an air filling pipe, and a water filling pipe, each equipped with a switch valve, are connected to the upper end of the mixer.

[0008] Preferably, the rotary drive mechanism includes a support plate fixedly connected to the cylinder and a second motor fixedly mounted on the support plate, the output end of the second motor being connected to a worm gear; the rotary drive mechanism also includes a worm wheel connected to the rotating frame and meshing with the worm gear.

[0009] Preferably, the connecting mechanism includes a connecting column with one end fixed to the rotating frame and the other end connected to a sleeve; the lower end of the mixer has a locking block that engages with the sleeve.

[0010] More preferably, the sleeve is provided with a snap-fit ​​assembly for limiting the position of the snap-fit ​​block.

[0011] More preferably, the locking assembly includes a locking seat fixedly connected to the sleeve and a movable block slidably installed inside the locking seat; a locking rod is fixedly connected to the inner side of the movable block, and a locking hole that cooperates with the locking rod is opened on the locking block; a spring for pushing the locking rod into the locking hole is also installed inside the locking seat; and a pull rod is fixed to the outer side of the movable block.

[0012] The beneficial effects of this utility model are as follows:

[0013] First, by setting up a mixer and pre-filling a standard amount of detergent in the mixer, this utility model achieves quantitative control of detergent spraying, resulting in a higher degree of standardization in washing operations. This effectively ensures the amount of detergent sprayed without wasting detergent.

[0014] Secondly, this utility model uses a rotary drive mechanism to drive the nozzle to rotate continuously around the mixing tank, spraying detergent under pressure. This allows for more even, longer-lasting, and higher-pressure spraying of detergent onto the inner wall of the tank and the mixing blades, effectively ensuring continuous high-pressure addition of detergent over a longer period, resulting in better cleaning performance.

[0015] Third, this invention can be cleaned with high-pressure air after washing with water, ensuring that the inner wall of the cylinder and the stirring blades are dry, preventing excess water from being carried into subsequent experiments and thus not affecting the accuracy of subsequent experiments.

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0021] like Figure 1 The laboratory mineral processing mixer, as an embodiment of this utility model, includes a cylindrical body 1 with a stirring shaft 12 equipped with blades 13 installed inside. A first motor 11 is fixedly installed at the bottom end of the cylindrical body 1.

[0022] The output end of the first motor 11 is connected to the lower end of the stirring shaft 12 via a coupling. The upper port of the cylinder 1 is provided with an end cover, which is closed during slurry stirring, water washing, and air drying, and left open when cleaning agent is added. The lower end of the cylinder 1 is connected to a hopper 14 for discharging slurry, washing water, or drying air.

[0023] Combination Figure 1 and Figure 2 A bearing seat 2 is installed on the outer wall of the cylinder 1, and a rotating frame 3 capable of rotating around the cylinder 1 is installed on the outer side of the bearing seat 2. Specifically, the bearing seat 2 is in the form of a bearing, with its inner ring fixed to the cylinder 1 and its outer ring fixed to the rotating frame 3.

[0024] This embodiment also includes a sealed container-type mixer 5, which is connected to the rotating frame 3 via a connecting mechanism 4. The lower end of the mixer 5 is connected to a horizontally positioned nozzle 6 located above the cylinder 1. The nozzle 6 is equipped with a downward nozzle 61 and an angled nozzle 62. The downward nozzle 6 sprays downwards, and the angled nozzle 62 sprays towards the inner wall of the cylinder 1.

[0025] This embodiment also includes a rotary drive mechanism 7 for driving the rotating frame 3 to rotate around the cylinder 1. The rotary drive mechanism 7 includes a support plate 71 fixedly connected to the cylinder 1 and a second motor 72 fixedly mounted on the support plate 71. The output end of the second motor 72 is connected to a worm gear 73 via a coupling. The rotary drive mechanism 7 also includes a worm wheel 74 connected to the rotating frame 3 and meshing with the worm gear 73. When the second motor 72 operates, it drives the worm gear 73 to rotate, which in turn drives the worm wheel 74 to rotate. The worm wheel 74 then drives the rotating frame 3 to rotate, and the rotating frame 3 drives the mixer 5 and the nozzle 6 to rotate.

[0026] Furthermore, the upper end of the mixer 5 is connected to a cleaning agent filling pipe 53, an air filling pipe 54, and a water filling pipe 55, each equipped with a switching valve.

[0027] Furthermore, the connecting mechanism 4 includes a connecting post 42, one end of which is fixed to the rotating frame 3 and the other end of which is connected to a sleeve 41. The lower end of the mixer 5 has a locking block 51 that engages with the sleeve 41.

[0028] Furthermore, combining Figure 3 The sleeve 41 is equipped with a locking assembly 8 for quickly limiting the position of the locking block 51. The locking assembly 8 includes a locking seat 81 fixedly connected to the sleeve 41 and a movable block 82 slidably installed inside the locking seat 81. A locking rod 83 is fixedly connected to the inner side of the movable block 82. Correspondingly, the locking block 51 has a locking hole 52 that cooperates with the locking rod 83. A spring 821 for pushing the locking rod 83 into the locking hole 52 is also installed inside the locking seat 81. A pull rod 822 extending outward from the locking seat 81 is fixed to the outer side of the movable block 82. The lock is unlocked when the pull rod 822 is manually pulled outward. This utility model makes the assembly and disassembly of the mixer 5 more convenient through the cooperative design of the sleeve 41 and the locking block 51 and the design of the locking assembly 8.

[0029] During cleaning, the slurry inside the cylinder 1 is discharged through the hopper 14, the upper end cover of the cylinder 1 is removed, and the valve of the hopper 14 is closed. Then, the valves on the cleaning agent filling pipe 53 and the air filling pipe 54 are opened. With the mixer 5 and the nozzle 6 rotating, high-pressure air is used to spray detergent onto the blades 13 and the inner wall of the cylinder 1 through the nozzles 61 and slanted nozzles 62. Afterward, the valves on the cleaning agent filling pipe 53 and the air filling pipe 54 are closed, and the valves on the water filling pipe 55 and the hopper 14 valve are opened to perform water rinsing using high-pressure water flow. Finally, the valve on the air filling pipe 54 is opened, and high-pressure airflow is used to dry the blades 13 and the inner wall of the cylinder 1.
