Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of flotation process, specifically a kind of for flotation reagent quantitative proportioning device. BACKGROUND

[0002] With the development of flotation reagent quantitative proportioning technology, various types of quantitative proportioning devices have been widely applied. These devices play an important role in improving flotation efficiency and reducing cost. However, there are still some problems in the actual use of existing quantitative proportioning devices.

[0003] For example, the intelligent flotation reagent quantitative adding system (publication date August 7, 2020) with publication number CN109794359B includes a main body, a reaction mechanism, a reagent adding mechanism and a discharge mechanism, which can automatically add flotation reagent and reduce manual operation. However, this system mainly focuses on the adding process of reagent, and lacks effective control of reagent mixing uniformity, especially when mixing multi-component reagent, which is prone to local uneven mixing, affecting the flotation effect. In addition, the control system used in this system is relatively simple, and the adaptability and stability for complex working conditions are insufficient.

[0004] On the other hand, the flotation reagent full-automatic quantitative mixing equipment (publication date December 26, 2023) with publication number CN117018942B has the function of layered mixing of raw materials, which can transport and mix different depths of liquid respectively, avoiding the phenomenon of uneven emulsification caused by liquid stratification inside the reagent preparation tank. However, this equipment mainly relies on mechanical stirring and layered transportation, and has weak dynamic proportioning and real-time adjustment capability, which is difficult to cope with rapidly changing working conditions. At the same time, the control system of this equipment is relatively complex, and the maintenance and debugging cost is high, which is not suitable for all industrial scenes.

Therefore, the utility model provides a new type of flotation reagent quantitative proportioning device with intelligent automatic adjustment to overcome these shortcomings and provide a new solution that is more intelligent, efficient and adaptable to changing environment.

[0030] The utility model provides a kind of for flotation reagent rationing device, specific conjunction description in annex Figures 1 to 5 , the structure, principle and embodiment of the utility model are described in detail.The utility model aims at solving the problem that the existing equipment is prone to local uneven mixing when mixing multi-component medicaments, and the problem of insufficient adaptability and stability under complex working conditions.By adding precisely controlled metering pump, mixer, heater, cooling device, pressure sensor, flowmeter and observation window, the utility model realizes accurate proportioning, uniform mixing and stable reaction of medicaments, improves the reliability and adaptability of flotation reagent proportioning device.

[0031] The utility model discloses an external reaction component 1, including dispensing box 11, mixing chamber 12 and reaction chamber 13.The top of dispensing box 11 is provided with feed inlet 111, the inside of feed inlet 111 is provided with filter screen 112, filter screen 112 is fixed in feed inlet 111 by fixed ring 113, to prevent impurities in medicaments from entering dispensing box 11.The upper and lower four corners of dispensing box 11 are provided with exhaust valve 114, the outer wall of dispensing box 11 is provided with air hole 115 matched with exhaust valve 114, to ensure the air pressure balance in dispensing box 11, avoid medicaments from fluctuating due to air pressure change.Mixing chamber 12 is symmetrically arranged on the both sides of dispensing box 11, and is provided with metering pump 21 inside.Reaction chamber 13 is arranged on the rear side of dispensing box 11, and is provided with mixer 22 and control unit 23 inside.Feed pipe 24 connects mixing chamber 12 and reaction chamber 13, and the other end of feed pipe 24 is connected with medicament tank 25.Flowmeter 241 is arranged on feed pipe 24, and display 242 is arranged on the surface of flowmeter 241, to monitor the delivery amount of medicaments in real time.Flowmeter 241 and display 242 belong to the public knowledge in the art, and are only used without modification, so the control mode and circuit connection are not described in detail.In one embodiment, the top inner wall of reaction chamber 13 is provided with heater (not shown), cooling device (not shown) and pressure sensor (not shown), and observation window 134 is arranged on the both sides of reaction chamber 13, to monitor the working state in reaction chamber 13 in real time.

[0032] In specific implementation, first, the required flotation reagents are added into the reagent tanks 25 through the feed ports 111, and the filter screens 112 in the feed ports 111 can effectively filter the impurities in the reagents to ensure the purity of the reagents. In the reagent tanks 25, different types of reagents are stored in different tank bodies to avoid cross contamination. The reagent tanks 25 are connected to the mixing chamber 12 through the feed pipes 24, and the flow meters 241 on the feed pipes 24 can accurately measure the delivery amount of the reagents and display it in real time through the displays 242. The control unit 23 controls the operation of the metering pumps 21 through electrical signals according to the preset proportioning ratio to ensure that the reagents are delivered to the mixing chamber 12 in a required and quantitative manner. The metering pumps 21 are symmetrically arranged on the inner wall of the mixing chamber 12 and can uniformly deliver the reagents to the center of the mixing chamber 12 to avoid local over-concentration or under-concentration of the reagents. The metering pumps 21 are commonly known in the art, and only their use is described without modification, so the control mode and circuit connection are not described in detail.

[0033] When the reagents reach the mixing chamber 12, they can be uniformly mixed according to the preset ratio through the accurate control of the metering pumps 21. The mixing chamber 12 is designed in a symmetrical structure, so that when the reagents are delivered through the metering pumps 21, a relatively uniform mixing area can be formed in the middle area, thereby avoiding the problem of uneven mixing in some areas. The mixed reagents are delivered to the reaction chamber 13 through the feed pipes 24, and the feed pipes 24 are designed with smooth inner walls to reduce the adhesion of the reagents during delivery and ensure that the reagents can smoothly enter the reaction chamber 13.

[0034] In the reaction chamber 13, the stirrer 22 is responsible for the further mixing and uniformity of the reagents. The stirrer 22 includes a motor 221 and a stirring shaft 222, and the motor 221 drives the stirring shaft 222 to rotate through a gear connection, thereby realizing efficient mixing of the reagents. The operation of the motor 221 is controlled by the control unit 23 through electrical signals, and the stirring speed can be adjusted according to the properties of the reagents and the reaction conditions to ensure that the reagents achieve the best mixing effect in the reaction chamber. In other embodiments, a heater and a cooling device can also be arranged on the top inner wall of the reaction chamber 13, which can adjust the temperature in the reaction chamber 13 in real time according to the needs of the reaction process to ensure that the reaction is carried out under suitable temperature conditions. The working state of the heater and the cooling device is controlled by the control unit 23 through electrical signals to realize accurate temperature adjustment.

[0035] A pressure sensor is also arranged on the top inner wall of the reaction chamber 13 to monitor the pressure change in the reaction chamber 13 in real time. The pressure sensor transmits the monitored pressure data to the control unit 23, and the control unit 23 adjusts the working conditions of the heater, the cooling device, and the exhaust valve 114 according to the preset pressure range to ensure that the pressure in the reaction chamber 13 remains within a safe range. This not only improves the stability of the reaction but also prolongs the service life of the equipment.

[0036] Two sides of the reaction chamber 13 are provided with observation windows 134 made of transparent high-temperature-resistant material, which can directly observe the mixing and reaction of the reagents in the reaction chamber 13 without affecting the reaction process. Through the observation window 134, the operator can find problems such as uneven mixing of reagents or abnormal reaction in time and take corresponding measures to adjust, thereby further improving the reliability of the equipment.

[0037] In a specific application scenario, the quantitative proportioning device for flotation reagents of the present application can be widely used in the fields of mine flotation, sewage treatment, chemical production, etc. Taking mine flotation as an example, the proportioning and mixing of flotation reagents directly affect the flotation effect and efficiency of the ore. In the traditional flotation reagent proportioning device, due to the uneven delivery and mixing of the reagents, the reagent effect is often unstable, affecting the progress of the flotation process. The present application realizes accurate proportioning and uniform mixing of reagents through the precisely controlled metering pump 21, high-efficiency stirrer 22, temperature regulating device (heater and cooling device) and pressure monitoring device (pressure sensor), ensures stable reaction of the reagents in the reaction chamber 13 and improves the flotation effect and efficiency. In the actual operation process, the operator can observe the mixing and reaction of the reagents in the reaction chamber 13 in real time through the observation window 134 and adjust various parameters through the control unit 23 to achieve the optimal reaction effect.

[0038] In order to further illustrate the specific embodiments of the present application, a specific example is described in detail below. Assuming that the flotation reagents to be proportioned include A, B and C, and the proportioning ratio is 1:2:1. First, reagents A, B and C are added to the corresponding reagent tanks 25, and the filter screen 112 in the feed inlet 111 ensures that the reagents are pure and free of impurities. Then, the control unit 23 sets the proportioning ratio of reagents A, B and C, and starts the metering pump 21. The metering pump 21 delivers reagents A, B and C into the mixing chamber 12 according to the set ratio, and the flow meter 241 on the delivery pipe 24 monitors the delivery amount of the reagents in real time to ensure the delivery accuracy of the reagents. The reagents in the mixing chamber 12 are uniformly delivered by the metering pump 21 to form a relatively uniform mixing area.

[0039] The mixed reagents are transported to the reaction chamber 13 through the delivery pipe 24, which is designed with smooth inner walls to reduce adhesion of the reagents during transportation, ensuring smooth entry of the reagents into the reaction chamber 13. In the reaction chamber 13, the motor 221 of the stirrer 22 is connected to the stirring shaft 222 through a gear, and the rotation speed of the motor 221 is adjusted by the control unit 23 according to the properties of the reagents and the reaction conditions, to achieve efficient mixing and uniform distribution of the reagents. The heater and cooling device adjust the temperature in the reaction chamber 13 in real time according to the required temperature conditions of the reaction. For example, if the reaction needs to be carried out at a higher temperature, the control unit 23 can start the heater through an electrical signal, and the heater raises the temperature in the reaction chamber 13 to the set value; if it needs to be carried out at a lower temperature, the control unit 23 starts the cooling device, and the cooling device lowers the temperature in the reaction chamber 13 to the set value. The pressure sensor monitors the pressure change in the reaction chamber 13 in real time and transmits the data to the control unit 23, which adjusts the working conditions of the heater, cooling device and exhaust valve 114 according to the preset pressure range, to ensure that the pressure in the reaction chamber 13 is within a safe range.

[0040] Through the observation window 134, the operator can directly observe the mixing and reaction of the reagents in the reaction chamber 13. For example, if the reagents are found to be mixed unevenly, the operator can adjust the stirring speed of the stirrer 22; if the reaction temperature is found to be too high or too low, the operator can adjust the working state of the heater and cooling device; if the reaction pressure is found to be abnormal, the operator can adjust it by controlling the opening and closing of the exhaust valve 114. In this way, the operator can take appropriate measures in a timely manner according to the actual situation, to ensure that the reagent ratio and reaction process achieve the best effect.

[0041] During use, the operator can set different mixing ratios and reaction conditions through the control unit 23 to meet the needs of different working conditions. The control unit 23 can be a control system containing a microprocessor and a human-machine interface, and the operator can operate it through a touch screen or buttons to set the required parameters. The control unit 23 will automatically adjust the working state of the metering pump 21, stirrer 22, heater, cooling device and exhaust valve 114 according to the set parameters, to realize automatic mixing of reagents and automatic control of the reaction process.

[0042] In addition, the flotation reagent quantitative proportioning device has high reliability and adaptability. For example, the high-efficiency heat conduction material is used in the design of the heater and the cooling device, so that the temperature can be rapidly changed in a short time, and the needs of different reaction conditions can be met. The combination of the flow meter 241 and the display 242 can display the delivery amount of the reagent in real time, so that the accuracy of the reagent proportioning is ensured. The design of the exhaust valve 114 and the air hole 115 can effectively balance the air pressure in the reagent box 11, so that the fluctuation of the reagent caused by the air pressure change is avoided, and the stability and safety of the equipment are improved.

[0043] In summary, the flotation reagent quantitative proportioning device of the utility model realizes the accurate proportioning and uniform mixing of the reagent by adding the accurately controlled metering pump 21, the high-efficiency stirrer 22, the temperature adjusting device (the heater and the cooling device), the pressure sensor, the flow meter 241 and the observation window 134, so that the stability and controllability of the reaction process are ensured, especially in complex working conditions. The utility model has practicality, reliability and adaptability, and can be widely used in the fields of mine flotation, sewage treatment, chemical production and the like, and the efficiency of the reagent proportioning and the reaction process is significantly improved.
