Description

Technical Field

[0001] This utility model relates to the field of flotation reagent preparation and dosing technology, and in particular to an automatic reagent preparation and dosing device for quartz flotation reagents. Background Technology

[0002] Flotation is a method of separation based on the differences in the physicochemical properties of mineral particles. By adding specific reagents (such as collectors, frothers, and inhibitors) to change the wettability of the mineral surface, it selectively adheres to air bubbles and floats, thereby achieving the separation of the target mineral from gangue minerals.

[0003] A search of Chinese Patent Publication No. CN211678264U reveals an automatic flotation reagent dosing device. However, this device is only effective for granular or semi-fluid reagents and its processing effect is poor. For reagents such as fatty acids and amines, which solidify at room temperature, this device is ineffective, leading to discontinuous flotation operations. Furthermore, this automatic dosing device lacks a backflow prevention mechanism, resulting in reagent backflow during flotation, causing raw material waste and affecting the accuracy of flotation reagent preparation. Therefore, we propose an automatic quartz flotation reagent dosing and preparation device to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that can only handle particulate or semi-fluid reagents with poor treatment effects and cannot prevent reagent backflow. Therefore, this invention proposes an automatic reagent preparation and dosing device for quartz flotation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic reagent preparation and dosing device for quartz flotation reagents includes:

[0007] Base;

[0008] Two medicine storage tanks are fixedly connected to the top of the base by a bracket;

[0009] Two anti-crystallization heating tubes are installed on the base and are respectively connected to the corresponding medicine storage tanks. Each anti-crystallization heating tube is equipped with a spiral stirring shaft and an electric heating tube. The spiral stirring shaft is driven by a drive motor fixed to the base.

[0010] Two drug inlet switches are installed on the top of the base and are respectively connected to the corresponding anti-crystallization heating tubes;

[0011] The mixing mechanism, installed on the top of the base and located between the two drug inlet switches, includes a venturi tube with drug inlets on both sides communicating with the drug inlet switches, a check valve inside, and a water inlet and a drug outlet at each end.

[0012] The agent is heated and stirred by the anti-crystallization heating tube, and then the flow rate is controlled by the inlet switch to enter the Venturi tube. After mixing with the water flowing in through the inlet, it is output from the outlet.

[0013] In one possible design, one end of the anti-crystallization heating tube extends into the corresponding medicine storage tank and is fixedly connected to the bottom of the medicine storage tank, and one end of the spiral stirring shaft extends to the outside of the anti-crystallization heating tube and is fixedly connected to the output shaft of the drive motor.

[0014] In one possible design, the drug inlet switch has an inlet and an outlet, the other end of the anti-crystallization heating tube is connected to the inlet, and the venturi tube is connected to the outlet through a conveying pipe.

[0015] In one possible design, the medicine storage tank is equipped with an alarm device, a leak detection device, and a liquid level detection device, with the alarm device connected to the leak detection device.

[0016] In one possible design, the inlet is provided with a connector assembly, including:

[0017] The regulating box is fixedly connected inside the water inlet;

[0018] The connecting pipe is fixedly connected to the inner wall of one side of the regulating box;

[0019] The valve seat is located inside the regulating box and has a spherical orifice;

[0020] The valve core is sealed and fitted inside the spherical orifice;

[0021] The stepper motor is fixedly installed on one side of the regulating box, and its output shaft is connected to the valve core.

[0022] In one possible design, a delivery pipe is fixedly connected inside the drug inlet of the venturi tube, and one end of the delivery pipe extends to the outside of the venturi tube and connects to the discharge port.

[0023] In one possible design, the check valve is attached to the inside of the venturi tube near the outlet.

[0024] In one possible design, the electric heating element is fitted onto the outer surface of the anti-crystallization heating element.

[0025] In one possible design, a workbench located between two medicine storage tanks is welded to the top of the base, and a guardrail is welded to the top of the workbench.

[0026] In this application, flotation reagents are stored in two separate storage tanks, one on the left and one on the right. The left tank stores anionic collectors, while the right tank stores cationic collectors. During reagent preparation, both types of reagents flow from their respective storage tanks into an anti-crystallization heating tube. As they pass through the anti-crystallization heating tube, a spiral stirring shaft, driven by a motor, agitates, crushes, and transports the flotation collectors. Simultaneously, an electric heating tube heats both collectors to 30-40°C. The heated reagents then flow through a feed switch, which controls the flow rate of the flotation collectors. The dosage of anionic and cationic collectors is controlled according to different quartz mineral types. The flotation collectors are then transported through a conveying pipe. The system can reach the Venturi tube. After connecting the pipeline for transporting deionized water to the connecting pipe, the stepper motor is started to drive the valve core to rotate. This allows the valve orifice on the valve core to be connected or disconnected from the ball orifice, thereby regulating the flow rate of water entering the Venturi tube. The deionized water entering the Venturi tube mixing device from the inlet has a larger inlet section. After the water flows through the mixing section, the flow rate increases. The anion and cation flotation collectors enter the Venturi tube mixing device from both ends of the inlet and mix with the deionized water. A check valve is set to prevent the backflow of the mixed reagents. Finally, the mixed flotation collectors flow out from the outlet, thus realizing the preparation of the flotation collectors.

[0027] Beneficial effects: In this utility model, the automatic dosing and feeding device for quartz flotation reagents can control the flow rate of the flotation collector after the reagent is delivered to the dosing switch through the anti-crystallization heating tube, and control the amount of anionic and cationic collectors according to different types of quartz minerals.

[0028] In this utility model, the automatic dosing and mixing device for quartz flotation reagents, through a mixing mechanism, can connect the venturi tube to the discharge port of the reagent mixing device through the two end inlets, and at the same time, it is connected to an external water supply pipe through a connector assembly. At this time, the water flow is introduced through the inlet, and different reagent ratios can be achieved by precisely controlling the flow rate of the water and the flow rate of the flotation reagent.

[0029] In this utility model, the automatic dosing and dispensing device for quartz flotation reagents, through the anti-crystallization heating tube, allows the reagents to flow out from the outlet pipe below the storage tank, pass through the anti-crystallization heating tube, and drive the spiral stirring shaft under the drive of the drive motor to stir, crush and transport the flotation collectors. At the same time, the electric heating tube heats the two collectors separately, so that the reagents can be heated during the transportation process.

[0030] This invention effectively prevents reagent solidification, improves reagent utilization, and reduces costs. It also utilizes a venturi tube combined with a check valve to prevent backflow and ensures reagent is dispensed in the correct proportions. The venturi tube plays multiple key roles in the flotation reagent addition process, including mixing, quantitative delivery, and anti-clogging, thus improving the continuity of flotation operations and the precision of flotation reagent preparation.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0038] Example 1: Refer to Figure 1-5A dosing device includes a base 5 made of metal, possessing sufficient strength and stability. At the top of the base 5, two storage tanks 1 are fixedly installed by welding using two sets of metal supports. The two storage tanks 1 are symmetrically distributed and are used to store different types of quartz flotation reagents, such as anionic collectors and cationic collectors.

[0039] Two anti-crystallization heating tubes 14 are installed on the base 5. These tubes are made of stainless steel, offering excellent corrosion resistance and thermal conductivity. One end of each anti-crystallization heating tube 14 extends into the corresponding medicine storage tank 1 and is welded to the bottom inner wall of the tank 1 to ensure a tight seal and prevent leakage. A spiral stirring shaft 141 is installed inside each anti-crystallization heating tube 14, with one end extending to the outside of the tube. Two drive motors 142 are bolted to the top of the base 5. The output shafts of the drive motors 142 are welded to one end of the spiral stirring shaft 141, allowing the motors to rotate the shaft. An electric heating tube 143 is also fixedly mounted on each anti-crystallization heating tube 14. The electric heating tube 143 is wrapped with a highly insulating material to ensure safe operation. When the reagent flows out from the outlet pipe below the storage tank 1 and enters the anti-crystallization heating tube 14, the drive motor 142 drives the spiral stirring shaft 141 to rotate, which stirs, crushes and transports the flotation collector. At the same time, the electric heating tube 143 heats the reagent, realizing the heating treatment of the reagent during the transportation process to prevent the reagent from crystallizing.

[0040] Two feed switches 2 are installed on the top of the base 5. The feed switches 2 use high-precision flow control valves with reliable sealing performance. The other end of the anti-crystallization heating tube 14 is fixedly connected to the feed port 21 of the feed switch 2, and the mixing mechanism is connected to the discharge ports 22 of the two feed switches 2 respectively. After the reagent is delivered into the feed switch 2 through the anti-crystallization heating tube 14, the feed switch 2 can precisely control the amount of anionic and cationic collectors according to different quartz mineral types, so as to achieve precise flow rate adjustment.

[0041] The mixing mechanism is located between the two drug inlet switches 2, specifically a Venturi tube 3 bolted to the top of the base 5. The Venturi tube 3 is made of engineering plastic or stainless steel, possessing good corrosion resistance and strength. Both sides of the inner wall of the Venturi tube 3 have drug inlets 31, with a delivery pipe 35 welded inside each inlet 31. One end of the delivery pipe 35 extends to the outside of the Venturi tube 3 and is fixedly connected to the corresponding outlet 22, ensuring that the drug can be smoothly delivered from the drug inlet switches 2 into the Venturi tube 3. A check valve 34 is bonded inside the Venturi tube 3 to prevent backflow of the drug. The Venturi tube 3 has an inlet 32 ​​and a outlet 33 at its two ends. A connector assembly is installed inside the inlet 32, including a regulating box 36 welded into it. One side of the regulating box 36 extends to the outside of the Venturi tube 3. A connecting pipe 310 is welded to the inner wall of one side of the regulating box 36. A valve seat 37 is welded inside the regulating box 36, and a spherical orifice is formed therein. A valve core 39 is sealed and fitted inside the spherical orifice. A stepper motor 38 is bolted to one side of the regulating box 36, and its output shaft extends into the regulating box 36 and is welded to the valve core 39. When the connecting pipe 310 is connected to an external water supply pipe, the stepper motor 38 is started to rotate the valve core 39, causing the valve orifice on the valve core 39 to either connect or disconnect from the spherical orifice, thereby regulating the flow rate of water entering the Venturi tube 3. After the water flows through the inlet 32 ​​into the venturi tube 3, it mixes with the reagent entering from the reagent inlet 31. By precisely controlling the flow rate of the water and the flow rate of the flotation reagent, different reagent ratios can be achieved. The well-mixed reagent is discharged from the outlet 33 and enters the subsequent flotation process.

[0042] This application can be used in the field of flotation reagent preparation and dosing technology, and can also be used in other fields applicable to this application.

[0043] Example 2: Reference Figure 1 An improvement upon Example 1: An automatic quartz flotation reagent preparation and dosing device, applied in the field of flotation reagent preparation and dosing technology, features a workbench 4 welded to the top of the base 5 between the two storage tanks 1. The workbench 4 is made of metal with a flat surface, facilitating worker standing and operation. A guardrail 41, made of metal and of moderate height, is welded to the top of the workbench 4 to effectively prevent workers from falling during operation, ensuring worker safety and facilitating maintenance of the two storage tanks 1.

[0044] An alarm device 11 is installed on the medicine storage tank 1. The alarm device 11 contains an alarm light and an alarm player. The alarm light uses a high-brightness LED, and the alarm player emits a loud alarm sound. When a drug leak occurs in the medicine storage tank 1, the alarm device 11 will promptly sound an alarm, allowing staff to quickly detect and take control measures. A liquid level detection device 13 is also installed inside the medicine storage tank 1. The top and bottom of the liquid level detection device 13 are connected to the top and bottom inner walls of the medicine storage tank 1, respectively. The liquid level detection device 13 is equipped with a level indicator that can sense the liquid level in the medicine storage tank 1 in real time and transmit the information to an external display device, allowing staff to monitor the liquid level in the medicine storage tank 1 at any time and replenish the medicine in a timely manner. A leak detection device 12 is also connected to the medicine storage tank 1. The alarm device 11 is connected to the leak detection device 12, which can monitor whether a drug leak has occurred in the medicine storage tank 1 in real time. Once a leak is detected, the alarm device 11 will immediately sound an alarm.

[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of the alarm device 11, the leak detection device 12, the liquid level detection device 13, the drive motor 142, the electric heating tube 143, and the stepper motor 38 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
