Description

Technical Field

[0001] This utility model relates to the technical field of flotation dosing devices, specifically an automatic flotation dosing device. Background Technology

[0002] Flotation reagent dosing equipment refers to a series of devices and technologies specifically used to add flotation reagents during the flotation process. Flotation is an important method in mineral processing, used to separate and enrich useful minerals. In this process, specific chemical reagents (including collectors, modifiers, frothers, etc.) are added to the slurry containing mineral particles to change the surface properties of the minerals, so that the target minerals can selectively adhere to the bubbles, thereby achieving the purpose of separation from other minerals.

[0003] In existing technologies, flotation reagents are added to the flotation machine via a conveying pipeline. However, the flotation reagents and minerals are not mixed evenly within the flotation machine, and reagents cannot be added in time when they are low, affecting the quality of the product. To avoid the above problems, an automatic reagent dosing mechanism for ilmenite flotation is disclosed in utility model publication number CN222428251U. In this solution, a level gauge is set up to achieve automatic reagent dosing and mixing when the liquid level drops, which has a high degree of automation and precise mixing.

[0004] However, due to the different proportions of various reagents, the consumption of reagents varies. Existing technologies can only add reagents according to the proportions and when they are low, but lack monitoring of the reagents themselves. Inspection and replacement must be done manually, and the reagent boxes are inconvenient to disassemble and reassemble during replacement, easily leading to problems such as missing individual reagents causing inaccurate proportions. Furthermore, regular manual inspections are required. Therefore, we propose an automatic flotation reagent dosing device. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 An automatic flotation reagent dosing device includes a mixing tank 1 for premixing added reagents, precisely controlling reagent concentration, and effectively improving reagent dispersibility and reaction efficiency. A motor 2 is fixedly mounted on the mixing tank 1, and an agitator 3 is fixedly mounted on the output shaft of the motor 2. The motor 2 drives the agitator 3 to rotate, thereby uniformly mixing the reagents. Multiple disassembly / assembly mechanisms 6 are provided at the top of the mixing tank 1, through which a liquid chamber 4 and a powder chamber 5 are installed. The liquid chamber 4 is used for precise addition of liquid reagents, and the powder chamber 5 is used for precise addition of powdered reagents. The disassembly / assembly mechanisms 6 are used for quick disassembly / assembly of the liquid chamber 4 or powder chamber 5 and for providing reminders when the liquid chamber 4 or powder chamber 5 needs to be replaced. A sample delivery pipe 7 is connected to the bottom of the mixing tank 1 for delivering the mixed reagents to the slurry for reaction.

[0029] Please see Figure 2 The liquid tank 4 includes a liquid tank 41 for storing liquid medicine. An armature 42 is fixedly installed at the bottom of the liquid tank 41. The armature 42 is used for quick installation and removal of the liquid tank 41. A metering pump 43 is fixedly installed at the bottom of the liquid tank 41 for precisely controlling the amount of liquid medicine added.

[0030] Please see Figure 3 The powder silo 5 includes a powder tank 51 for storing powder. An armature 2 52 is fixedly installed at the bottom of the powder tank 51. The armature 2 52 is used for quick installation and removal of the powder tank 51. A screw feeder 53 is fixedly installed at the bottom of the powder tank 51 for precisely controlling the amount of powder added.

[0031] Please see Figures 4-6 Multiple disassembly and assembly mechanisms 6 are arranged in a circular array. Each disassembly and assembly mechanism 6 includes an installation groove 61, which is located at the top of the mixing tank 1. An electromagnet 62 is slidably installed in the installation groove 61. By controlling the magnetism of the electromagnet 62, the electromagnet 62 can quickly connect and disconnect magnetically with armature 42 or armature 52, thus having the characteristics of fast disassembly and assembly speed and convenient disassembly and assembly.

[0032] The mixing tank 1 has sliding grooves 64 on both sides of the mounting groove 61. A buzzer alarm 65 is fixedly installed at the top of the sliding groove 64. A marker rod 63 is fixedly installed on the surface of the electromagnet 62. The marker rod 63 is compatible with the sliding groove 64. The bottom of the electromagnet 62 and the mounting groove 61 are fixedly connected by multiple springs. When the material usage in the liquid tank 41 or powder tank 51 decreases, the spring force will drive the electromagnet 62 to slide along the mounting groove 61. The sliding of the electromagnet 62 will drive the marker rod 63 to slide synchronously along the sliding groove 64 until the marker rod 63 contacts the top of the sliding groove 64. The marker rod 63 and the top of the sliding groove 64 are electrically connected and in a continuous state. Because the top of the sliding groove 64 is electrically connected to the buzzer alarm 65, an electrical path is formed between the marker rod 63, the top of the sliding groove 64, and the buzzer alarm 65, thereby triggering the buzzer alarm 65 to remind the staff to change the reagent.

[0033] An automatic flotation dosing device, the working principle of which is as follows:

[0034] By adding reagents according to the ratio, the metering pump 43 accurately measures the liquid medicine added to the mixing tank 1 from the liquid tank 41, the screw feeder 53 accurately measures the powder medicine added to the mixing tank 1, and then the motor 2 drives the stirring paddle 3 to make the medicine premixed evenly. The automation level is high and the mixing is accurate.

[0035] As the medicine is gradually added to the liquid tank 41 or powder tank 51, the dosage and weight of the medicine in the liquid tank 41 or powder tank 51 decrease. Under the action of the spring force, the electromagnet 62 slides upward along the mounting groove 61. The upward sliding of the electromagnet 62 drives the marker rod 63 to slide synchronously along the sliding groove 64 until the medicine in the liquid tank 41 or powder tank 51 is close to empty. At this point, the marker rod 63 contacts the top of the sliding groove 64, thereby triggering the buzzer alarm 65, which then sounds to remind the staff to replace the liquid tank 4 or powder tank 5.

[0036] When replacing the liquid hopper 4 or powder hopper 5, the magnetic connection between the electromagnet 62 and armature 42 or armature 52 can be controlled by de-energizing the corresponding electromagnet 62, thus enabling rapid replacement of the liquid hopper 4 or powder hopper 5. This effectively prevents insufficient dosage of the reagent in the liquid hopper 4 or powder hopper 5.
