Description

Technical Field

[0001] This utility model relates to the field of flocculant preparation technology, specifically to an automatic flocculant preparation system. Background Technology

[0002] In mineral processing, the scientific formulation of flocculants is crucial, directly impacting the settling effect and beneficiation efficiency of the slurry. The traditional method involves directly adding the flocculant to the slurry mixing tank along with a suitable amount of water. This simple method has several drawbacks. The flocculant is difficult to fully dissolve, especially at low temperatures, leading to the formation of numerous large flocs. These flocs come into direct contact with the slurry, significantly reducing the effective utilization rate of the flocculant, increasing its consumption, and potentially causing blockages in the delivery pipelines, severely affecting the stability and continuity of the production process. Furthermore, the traditional method makes it difficult to precisely control the flocculant concentration, resulting in unsatisfactory slurry settling. When the properties of the ore change, the amount of flocculant added cannot be adjusted in time, leading to either insufficient supply resulting in poor settling or oversupply and resource waste.

[0003] Therefore, there is an urgent need to develop an automatic flocculant preparation system to solve the problems existing in the traditional preparation method, improve the utilization rate of flocculants, reduce production costs, and ensure the efficient and stable operation of the mineral processing process. Utility Model Content

[0004] This invention provides an automatic flocculant preparation system. The system features intelligent control, enabling precise control of the flocculant dosage and dissolution process. It also automatically adjusts the dosage based on real-time changes in ore properties, thereby effectively improving flocculant utilization.

[0005] The specific technical solution is as follows:

[0006] An automatic flocculant preparation system includes multiple mixing tanks connected in series. The top inlet of the first-stage mixing tank is equipped with a water inlet pipe and a feed box. A solenoid valve and a flow meter are installed on the water inlet pipe, and a screw feeder is installed at the bottom of the feed box. The outlet of the last-stage mixing tank is connected to the top inlet of a dilution tank via a pipe. The top inlet of the dilution tank is also equipped with a dilution water pipe and a level gauge, and an outlet pipe is located below the side wall. A solenoid valve and a flow meter are installed on the dilution water pipe. The solenoid valve, flow meter, screw feeder, level gauge, solenoid valve, and flow meter are all electrically connected to a controller. Both the mixing tank and the dilution tank are equipped with a stirring device.

[0007] Furthermore, preferably, the mixing tanks are connected in series in three stages, with the upper side wall of the first stage mixing tank connected to the corresponding position of the second stage mixing tank, the lower side wall of the second stage mixing tank connected to the corresponding position of the third stage mixing tank, and the upper side wall of the third stage mixing tank connected to the top feed inlet of the dilution tank via a pipe.

[0008] Furthermore, preferably, the water inlet pipe is equipped with a water inlet temperature control system at its front end. The water inlet temperature control system includes a cold water tank, the outlet of which is connected to the inlet of a warm water tank via a heat pump, and the outlet of the warm water tank is connected to the water inlet pipe.

[0009] The beneficial effects of this invention are as follows: This system organically combines multi-stage stirring with warm water preparation, significantly improving flocculant dissolution efficiency and effectively preventing the formation of lumpy flocs, thereby increasing flocculant utilization and reducing resource waste. Simultaneously, through automated control and real-time concentration monitoring, the system ensures the stability of the flocculant solution concentration, thus guaranteeing the reliability of the slurry flocculation and sedimentation effect. Furthermore, based on real-time liquid level monitoring data, the system automatically adjusts the flocculant output, flexibly adapting to changes in ore properties and effectively preventing oversupply or undersupply. This intelligent design also reduces the frequency of manual intervention and maintenance needs, thereby lowering operating costs and achieving a more intelligent and efficient flocculant preparation process.

[0015] like Figure 1 As shown, this embodiment provides an automatic flocculant preparation system, including three-stage series mixing tanks 9. The top inlet of the first-stage mixing tank 901 is equipped with a water inlet pipe 4 and a feed box 7. A solenoid valve 5 and a flow meter 6 are installed on the water inlet pipe 4, and a screw feeder 8 is installed at the bottom of the feed box 7. The upper side wall of the first-stage mixing tank 901 is connected to the corresponding position of the second-stage mixing tank 902, the lower side wall of the second-stage mixing tank 902 is connected to the corresponding position of the third-stage mixing tank 903, and the upper side wall of the third-stage mixing tank 903 is connected to the top inlet of the dilution tank 10 via a pipe. The top inlet of the dilution tank 10 is also equipped with a dilution water pipe 11 and a level gauge 14, and an outlet pipe 15 is installed at the lower side wall. A solenoid valve 12 and a flow meter 13 are installed on the dilution water pipe 11. Solenoid valve 5, flow meter 6, screw feeder 8, level gauge 14, solenoid valve 12, and flow meter 13 are all electrically connected to controller 16, enabling automatic control. Furthermore, both mixing tank 9 and dilution tank 10 are equipped with stirring devices 17, which ensure the flocculant is fully dissolved through stirring.

[0016] As a preferred embodiment, an inlet water temperature control system is also provided at the front end of the inlet pipe 4. The inlet water temperature control system includes a cold water tank 1. The outlet of the cold water tank 1 is connected to the inlet of the warm water tank 3 through a heat pump 2. The outlet of the warm water tank 3 is connected to the inlet pipe 4, thereby ensuring that the water temperature entering the system is constant at 20-30℃, which is conducive to the full dissolution of the flocculant.

[0017] Working Principle: During operation, water from cold water tank 1 is pumped to warm water tank 3 via heat pump 2, heating and maintaining the water temperature within the range of 20-30℃. The water then enters the primary mixing tank 901 via inlet pipe 4. Simultaneously, flocculant particles from feed tank 7 are continuously and quantitatively added to the primary mixing tank 901 via screw feeder 8. The flocculant particles and water initially mix and dissolve in the primary mixing tank 901, then flow from the overflow port above the side wall of the primary mixing tank 901 to the secondary mixing tank 902 for further dissolution. Subsequently, the flocculant continues to flow from the bottom connection port of the secondary mixing tank 902 to the tertiary mixing tank 903. After multiple stages of mixing, the flocculant is fully dissolved, forming a uniform flocculant solution. Finally, the flocculant solution flows through the overflow port above the side wall of the tertiary mixing tank 903 via a pipe to the dilution tank 10 for dilution.

[0018] During operation, water from cold water tank 1 is pumped to warm water tank 3 via heat pump 2, heating and maintaining the water temperature within the range of 20-30℃. The water is then pumped to primary mixing tank 901 via inlet pipe 4. Simultaneously, flocculant particles from feed tank 7 are continuously and quantitatively added to primary mixing tank 901 via screw feeder 8. In primary mixing tank 901, the flocculant particles and warm water undergo preliminary mixing and dissolution. Next, the preliminarily dissolved flocculant solution flows from the overflow port above the side wall of primary mixing tank 901 into secondary mixing tank 902 for further dissolution. The further dissolved solution flows from the connecting port at the bottom of secondary mixing tank 902 into tertiary mixing tank 903. Thus, through multi-stage stirring, the flocculant is fully dissolved, forming a homogeneous flocculant solution. This solution then flows through the overflow port above the side wall of tertiary mixing tank 903 into dilution tank 10 for dilution.

[0019] At this point, controller 16 estimates the feed concentration of the flocculant solution based on the operating status of solenoid valve 5, flow meter 6, and screw feeder 8, and compares it with the preset target concentration. Based on the concentration difference, controller 16 precisely controls solenoid valve 12 on dilution water pipe 11, and simultaneously adjusts the flow rate of the dilution water using real-time flow data provided by flow meter 13, ensuring that the diluted flocculant solution accurately reaches the target concentration requirement. Finally, the diluted, qualified flocculant solution is transported to the mineral processing stage through outlet pipe 15.

[0020] Meanwhile, the level gauge 14 monitors the liquid level changes in the dilution tank 10 in real time. When the liquid level is below the set lower limit, the controller 16 automatically starts the feeding and water supply process to replenish the flocculant solution in a timely manner; while when the liquid level reaches or exceeds the upper limit, the controller 16 automatically stops the feeding and water supply process. Through this intelligent control system, the automatic configuration and stable supply of flocculant solution are realized, effectively meeting the continuous needs of mineral processing production.
