Description

Technical Field

[0001] This utility model relates to the field of coal flotation technology, specifically to a biological flotation agent addition device. Background Technology

[0002] A crucial step in coal washing is froth flotation, a separation process that utilizes the difference in hydrophilicity and hydrophobicity between the surfaces of coal and gangue. To improve flotation efficiency and separation selectivity, frothers and collectors are added. Both frothers and collectors are flotation agents used to regulate and control the flotation process, weakening or improving the floatability of the material to facilitate the separation of gangue from ore, thereby removing impurities or extracting useful mineral particles. Collectors enhance the hydrophobicity of the coal surface, while frothers stabilize the froth and carry coal particles to the surface.

[0003] Traditional reagent addition involves first adding coal-water slurry to a container of a certain volume, then using a graduated cylinder to collect flotation reagent from a tap, adding it to the slurry, and mixing. The amount of flotation reagent added is determined manually, which introduces significant errors, is cumbersome, and results in either insufficient addition affecting separation efficiency or excessive addition wasting reagent and increasing costs. Furthermore, the different materials used for the taps lead to significant leakage over long periods, making accurate measurement difficult, and the existing addition method is inefficient.

[0004] Flotation reagents are diverse, some with high fluidity, some with high viscosity, and some are emulsified oils, thus limiting their applicability to reagent dosing systems. High-viscosity flotation reagents have poor fluidity, and different components exhibit varying kinematic viscosities, affecting performance during seasonal changes and making it difficult to control the dosage. Therefore, existing technologies require further improvement and enhancement. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A bioflotation agent addition device includes a storage unit, a buffer tank, a slurry processor, an electromagnetic flow pump, and an electrical control box. The slurry processor includes a slurry tank with a top cover, a feed pipe at the bottom of the slurry tank, a discharge pipe on one side of the top, and an electronic flow meter on the feed pipe.

The storage unit includes a storage tank, and an electric heating plate is provided at the bottom of the storage tank. The inlet of the electromagnetic flow pump is connected to the outlet pipe at the bottom of the storage tank through the buffer tank.

[0009] The slurry mixing tank is equipped with a conveying coil, an atomizing nozzle, and a stirring mechanism. The conveying coil is arranged in a spiral manner, and its upper end is connected to the outlet of the electromagnetic flow pump through a connecting pipe. The atomizing nozzle is located at the lower end of the conveying coil and is equipped with a temperature sensor. The outlet of the atomizing nozzle is aligned with the rotation direction of the coal-water slurry inside the slurry mixing tank.

[0010] The electrical control box contains a master switch and a PLC controller. The signal terminals of the electronic flow meter, temperature sensor, and electromagnetic flow pump are respectively connected to the PLC controller for communication.

[0017] The conveying coil has two spiral blades on each side along its circumference. The two spiral blades on both sides of the conveying coil are on the same plane and are fixedly connected to the outer wall of the conveying coil as a whole.

[0018] By adopting the above technical solution, the beneficial technical effects of this utility model are as follows: This utility model can heat and keep warm the flotation agent with high viscosity during the transportation process, so that the flotation agent has good fluidity, has a high degree of automation, accurately measures the amount of flotation agent added, reduces the waste of flotation agent, lowers the cost of use, and continuously adds water-coal slurry and flotation agent separately through automatic control, thereby improving production efficiency.

[0021] The present invention will now be described in detail with reference to the accompanying drawings:

[0022] Combination Figure 1 and Figure 2 A bioflotation agent addition device includes a storage unit, a buffer tank 12, a slurry processor 5, an electromagnetic flow pump 10, and an electrical control box 9. The slurry processor 5 includes a slurry tank with a top cover. The bottom of the slurry tank has an inlet pipe, and one side of the top has an outlet pipe. An electronic flow meter 8 is installed on the inlet pipe. The electrical control box 9 contains a master switch and a PLC controller. The signal terminals of the electronic flow meter 8, temperature sensor, and electromagnetic flow pump 10 are respectively connected to the PLC controller. Coal-water slurry is pumped into the slurry tank through the inlet pipe. The electronic flow meter 8 records the flow rate of the coal-water slurry through the inlet pipe in real time and sends the flow data to the PLC controller. The coal-water slurry and flotation agent are thoroughly mixed inside the slurry tank. Afterward, the mixture is discharged through the outlet pipe at the top of the slurry tank and enters the flotation machine.

[0023] Both the storage unit and the electromagnetic flow pump 10 are positioned above the slurry preparation processor 5. The storage unit includes a storage tank 1, the bottom of which is fixedly connected to the top cover of the slurry preparation processor 5 via a tank support 4. A reagent inlet is located at the top of the storage tank 1. An electric heating plate 3 is installed at the bottom of the storage tank 1, and a liquid level window 2 is provided on the side wall of the storage tank 1. The outlet of the storage tank 1 is located on its lower side and is connected to the inlet at the top of the buffer tank 12 via a first pipe. In operation, the electric heating plate 3 is activated to heat the flotation reagent inside the storage tank 1, ensuring the flotation reagent is within a set temperature range and possesses good fluidity.

[0024] The inlet of the electromagnetic flow pump 10 is connected to the outlet pipe at the bottom of the storage tank 1 via the buffer tank 12. Specifically, the buffer tank 12 is a closed structure with an insulation layer 11 on its outer wall. The outlet at the bottom of the buffer tank 12 is connected to the inlet of the electromagnetic flow pump 10 via a second pipe. Both the first and second pipes are equipped with automatic control valves, which are communicatively connected to the PLC controller.

[0025] The flotation reagent is added into the storage tank 1 through the inlet at the top. The amount of flotation reagent inside the storage tank 1 is observed through the level window 2 located on the side wall of the storage tank 1. When the amount of flotation reagent inside the storage tank 1 is less than the set value, flotation reagent continues to be added to the storage tank 1 to ensure a sufficient supply of flotation reagent. In operation, the electromagnetic flow pump 10 pumps the flotation reagent in the storage tank 1 into the conveying coil 6 through the buffer tank 12 and sprays it into the slurry preparation tank through the atomizing nozzle 7. At the same time, the electromagnetic flow pump 10 monitors the flow rate of the flotation reagent in real time and sends the flow rate data to the PLC controller. The PLC controller adjusts the flotation reagent flow rate of the electromagnetic flow pump 10 according to the set program and through instructions, so that the amount of flotation reagent added is positively correlated with the amount of coal-water slurry added.

[0026] The upper part of the mixing tank is cylindrical and the lower part is conical. The interior of the mixing tank is equipped with a conveying coil 6, an atomizing nozzle 7 and a stirring mechanism. The conveying coil 6 is arranged in a spiral manner and its outer contour is cylindrical. The center line of the conveying coil 6 coincides with the axis of the mixing tank. The upper end of the conveying coil 6 is connected to the outlet of the electromagnetic flow pump 10 through a connecting pipe. The atomizing nozzle 7 is located at the lower end of the conveying coil 6 and is fixedly connected to the inner wall of the mixing tank through a nozzle bracket.

[0027] A temperature sensor is installed inside the atomizing nozzle 7. The outlet direction of the atomizing nozzle 7 is consistent with the rotation direction of the coal-water slurry inside the slurry mixing tank. The flotation reagent sprayed through the atomizing nozzle 7 moves and mixes with the coal-water slurry inside the tank. The temperature sensor monitors the temperature of the flotation reagent inside the atomizing nozzle 7 in real time to maintain good fluidity and atomization effect. When the temperature value detected by the temperature sensor is lower than the set value, the temperature of the flotation reagent inside the storage tank 1 can be increased by the electric heating plate 3.

[0028] Two spiral blades 61 are provided on both sides of the conveying coil 6 along its circumference. The two spiral blades 61 on both sides of the conveying coil 6 are on the same plane and are fixedly connected to the outer wall of the conveying coil 6 as a whole. The connecting pipe is vertically installed on the top cover. Its upper end is connected to the outlet of the electromagnetic flow pump 10 and its lower end is connected to the upper end of the conveying coil 6.

[0029] The mixing mechanism includes a mixing shaft, a servo motor, and multiple blades. The mixing shaft is coaxially arranged with the mixing tank. The servo motor is mounted on the top surface of the mixing processor 5, and its output shaft is coaxially and fixedly connected to the mixing shaft. All blades are located below the conveying coil 6, and are evenly arranged in a ring around the mixing shaft and fixedly connected to the side wall of the mixing shaft as one unit.

[0030] In use, the stirring mechanism stirs the coal-water slurry and flotation agent inside the slurry tank. The spirally arranged conveying coil 6 and the spiral blades 61 on both sides can guide the coal-water slurry and flotation agent to flow upward to the discharge pipe. At the same time, the conveying coil 6 and the spiral blades 61 can improve the uniformity of the flotation agent and the coal-water slurry, as well as the utilization efficiency of the flotation agent.
