Description

Technical Field

[0001] This utility model relates to the field of flotation machine reagent addition technology, specifically a gold ore flotation reagent addition device. Background Technology

[0002] In the field of gold mining and beneficiation, flotation is one of the core technologies for recovering gold minerals. Its efficiency directly determines the utilization rate of gold resources and the economic benefits of enterprises. In the flotation process, the ratio of reagents is crucial. Whether it is xanthate compounds as collectors, pine oil as frothers, or lime and sulfuric acid as modifiers, the correct ratio of their contents will have a significant impact on the surface properties of minerals and the adsorption effect of bubbles, ultimately determining the gold recovery rate and concentrate grade.

[0003] However, in the use of existing technologies, traditional gold ore flotation reagent addition devices mostly rely on manual operation to weigh and feed reagents. There is a time difference between weighing and feeding, and the actual amount of reagents added is prone to deviation due to problems such as reagent spillage and measurement errors. It is difficult to form a stable ratio, which not only causes large fluctuations in reagent ratio accuracy, but also affects the effectiveness of flotation reagents due to ratio imbalance, resulting in unstable gold recovery rate and increased production costs. Therefore, a gold ore flotation reagent addition device is proposed. Utility Model Content

[0016] Please see Figure 1-5 This utility model provides a technical solution: a gold ore flotation reagent addition device, including a mixing cylinder 1, a limiting box 3 fixedly connected to the upper surface of the mixing cylinder 1, a pressure sensor 13 fixedly connected to the upper surface of the mixing cylinder 1, and a weighing box 5 fixedly connected to the upper surface of the pressure sensor 13. The pressure sensor 13 weighs the reagent poured into the weighing box 5, ensuring the accuracy of the reagent ratio. Sliding blocks 24 are fixedly connected to both the front and rear sides of the weighing box 5. A sliding groove 15 is provided inside the limiting box 3, and the inner wall of the sliding groove 15 contacts the outer surface of the sliding block 24. The sliding groove 15 limits the position of the sliding block 24, keeping the weighing box 5 under the limiting action of the sliding groove 15 as materials are added. When the weighing box 5 is in a stable position, a limiting groove 14 is provided inside the weighing box 5. A baffle 12 is slidably connected inside the limiting groove 14. Through the cooperation between the baffle 12 and the limiting groove 14, the bottom of the weighing box 5 is sealed when material is put into the weighing box 5. A fixing rod 6 is fixedly connected to one end of the baffle 12. A top cover 9 is rotatably connected to the top of the weighing box 5. A fixing block 8 is fixedly connected to the upper surface of the top cover 9. A connecting rod 7 is rotatably connected inside the fixing block 8. The end of the connecting rod 7 away from the fixing block 8 is rotatably connected to the inside of the fixing rod 6. Through the cooperation between the fixing block 8 and the connecting rod 7, the baffle 12 is made to contact the inner wall of the limiting groove 14 tightly when the top cover 9 is opened.

[0017] The mixing cylinder 1 has an injection pipe 4 on its upper surface, a water level pipe 2 fixedly connected to its surface, and a discharge pipe 10 fixedly connected to the outer surface of the mixing cylinder 1 on the side away from the water level pipe 2. The water level pipe 2 is used to observe the capacity of the solution inside the mixing cylinder 1.

[0018] The lower surface of the mixing cylinder 1 is fixedly connected to a motor 11, and the output end of the motor 11 is fixedly connected to a transmission rod 21 through a coupling. The motor 11 drives the transmission rod 21 to rotate.

[0019] Among them, a locking block 22 is fixedly connected to the outer surface of the transmission rod 21, and a sleeve rod 17 is provided on the outer surface of the transmission rod 21.

[0020] The sleeve rod 17 has a groove 23 inside, and the inside of the groove 23 is slidably connected to the outer surface of the block 22. Through the cooperation between the groove 23 and the block 22, the sleeve rod 17 is driven to rotate.

[0021] The inner top wall of the mixing cylinder 1 is fixedly connected to a lead screw 16, and the top end of the sleeve rod 17 is sleeved on the outer surface of the lead screw 16. Through the helical transmission between the sleeve rod 17 and the lead screw 16, the sleeve rod 17 can move up and down.

[0022] Among them, the outer surface of the sleeve rod 17 is fixedly connected to a fixed frame 18 arranged in a circular array, and the surface of the fixed frame 18 is fixedly connected to a stirring plate 19. The fixed frame 18 serves to limit and fix the position of the stirring plate 19.

[0023] Among them, a scraper 20 is fixedly connected to the end of the fixed frame 18 away from the sleeve rod 17. The outer surface of the scraper 20 is in contact with the inner wall of the mixing cylinder 1. Through the scraping action between the scraper 20 and the inner wall of the mixing cylinder 1, the material is prevented from adhering to the inner wall of the mixing cylinder 1, reducing the difficulty of subsequent cleaning.

[0024] The motor is existing technology and will not be discussed in detail here. The components that match the motor include connecting wires, power supply, and microcontroller, which are also existing structures and will not be discussed in detail here.

[0025] Working principle: In use, firstly, the solution is injected into the injection pipe 4 using the water supply device. Then, the water level pipe 2 is observed to determine the volume of the solution injected into the mixing cylinder 1. The corresponding weight of the added agent is then calculated. Next, the top cover 9 is opened, causing the top cover 9 to rotate the fixing block 8, which moves the connecting rod 7 downward. This pushes the fixing rod 6 and the baffle 12 downward under the limiting action of the limiting groove 14 until the baffle 12 is in close contact with the inner wall of the limiting groove 14, sealing the bottom of the weighing box 5. At this point, the required agent is poured into the weighing box 5, and the weight of the material poured into the weighing box 5 is monitored at all times by the pressure sensor 13. When the required weight is reached, the fixing block 8 is closed, causing the top cover 9 and the fixing block 8 to move the connecting rod 7 and the fixing rod 6 upward, moving the baffle 12 from the bottom of the weighing box 5. The inside of the limiting groove 14 is pulled out, and the medicine inside the weighing box 5 slides down from the bottom of the weighing box 5 into the inside of the mixing cylinder 1. Then, the motor 11 is started, and the motor 11 drives the transmission rod 21 and the locking block 22 to rotate. Under the limiting action of the locking groove 23, the locking block 22 drives the sleeve rod 17 to rotate. At this time, the sleeve rod 17 and the lead screw 16 are screwed together, so that the sleeve rod 17 moves up and down on the surface of the lead screw 16. This further causes the sleeve rod 17 to move up and down while driving the stirring plate 19 to rotate, stirring the liquid at different depths inside the mixing cylinder 1, ensuring the uniformity of the medicine mixing, and achieving rapid mixing. At the same time, the scraper 20 scrapes against the inner wall of the mixing cylinder 1 to prevent the material from adhering to the inner wall of the mixing cylinder 1, reducing the difficulty of subsequent cleaning, and ensuring the accuracy of the medicine ratio.
