Description

Technical Field

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

[0002] In the process of efficient utilization of coal resources, flotation technology, as an important coal separation method, can effectively improve coal quality and reduce ash and sulfur content. With the continuous enhancement of environmental awareness and the increasing requirements for coal quality, bio-flotation agents have been increasingly widely used in the field of coal flotation due to their advantages such as being green, environmentally friendly, and biodegradable.

[0003] Currently, in the flotation devices used in the coal flotation process, the stirring rod is usually fixed in a specific position in the mixing tank. During the mixing process, the area that the stirring rod can cover is limited, making it difficult to fully and thoroughly mix the coal and bioflotation agent in the mixing tank. This results in uneven mixing of coal and bioflotation agent, and some coal cannot fully contact the flotation agent, thus affecting the flotation effect and reducing the separation efficiency and quality of coal.

[0004] Furthermore, in the coal flotation process, the dosage of bio-flotation reagent plays a crucial role in the flotation effect. However, some existing flotation devices cannot accurately control the amount of flotation reagent added automatically, which can easily lead to dosage deviations during the addition process, thus hindering practical use.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Example 1, combined with Figures 1 to 6A flotation device for biological flotation agents includes a flotation tank 15, a mounting plate 1 fixedly connected to the top of the flotation tank 15, the mounting plate 1 being U-shaped, a rectangular opening 2 at the top of the mounting plate 1, a support block 3 slidably connected between the inner walls of the two sides of the rectangular opening 2, a transmission pipe 4 fixedly connected to the top of the support block 3, one end of the transmission pipe 4 passing through the support block 3 and extending into the flotation tank 15; an aeration and stirring mechanism, which works in conjunction with the transmission pipe 4 and is located inside the flotation tank 15; a transmission assembly, located at the top of the inner cavity of the mounting plate 1, fixedly connected to the support block 3, and used in conjunction with the aeration and stirring mechanism; and a quantitative dispensing mechanism, located at the top of the mounting plate 1, which works in conjunction with the support block 3 and the transmission assembly.

[0036] like Figures 1 to 5 As shown, the aeration and stirring mechanism includes an aeration shell 5, an aeration shell 5 fixedly connected to the bottom end of a transmission pipe 4, aeration holes 6 evenly distributed on the top of the aeration shell 5, stirring blades 7 fixedly connected to the top of the aeration shell 5, stirring rods 8 evenly distributed on the side wall of the transmission pipe 4, an aeration pump 31 installed on one side of the mounting plate 1, an air pipe 32 installed at the top air outlet of the aeration pump 31, and one end of the air pipe 32 movably connected to the top end of the transmission pipe 4.

[0037] like Figure 3 and Figure 5 As shown, the transmission assembly includes a slide tube 10. The slide tube 10 is fixedly connected to one side of the support block 3. A reciprocating screw 9 is installed inside the slide tube 10. Both ends of the reciprocating screw 9 pass through the mounting plate 1 and are movably connected to the mounting plate 1. A motor 11 is installed on one side of the mounting plate 1. The output end of the motor 11 is fixedly connected to one end of the reciprocating screw 9. A horizontal plate 13 is fixedly connected to the top of the inner cavity of the mounting plate 1. A rack 14 is fixedly connected to the side of the horizontal plate 13 opposite to the transmission tube 4. A gear 12 is fixedly connected to the side wall of the transmission tube 4 near the top. The gear 12 meshes with the rack 14.

[0038] The reciprocating screw 9 and the slide tube 10 in this invention are a relatively mature existing technology. When the reciprocating screw 9 rotates, it can drive the slide tube 10 to slide back and forth. The working principle of its reciprocating sliding is common knowledge in the field and therefore will not be described in detail in this technical solution. The motor 11 is a common driving device in the present invention. Its installation method and working principle are common knowledge in the field and will not be described in detail in this technical solution. In addition, in actual use, the rotation speed of the motor 11 should not be too fast. It needs to be used in conjunction with a transformer according to the actual situation. Through the transmission mechanism, the transmission tube 4 can be driven to move back and forth left and right, and rotate in both directions during displacement. This can increase the stirring area in the flotation tank 15, thereby increasing the mixing effect and improving the mixing efficiency through aeration.

[0039] Example 2, as Figures 1 to 6 As shown, the quantitative dispensing mechanism includes a quantitative tube 16. The quantitative tube 16 is fixedly connected to the top of the mounting plate 1. A crossbar 17 is provided inside the quantitative tube 16. A piston plate 18 is fixedly connected to one end of the crossbar 17, and a rectangular plate 21 is fixedly connected to the other end of the crossbar 17 to the outside of the quantitative tube 16. The bottom of the rectangular plate 21 is slidably connected to the top of the mounting plate 1. An adjustment mechanism is provided on the side wall of the crossbar 17. A fixing plate 22 is fixedly connected to the top of the mounting plate 1. A tension spring 23 is fixedly connected between the fixing plate 22 and the rectangular plate 21. A push plate 33 is fixedly connected to the top of the support block 3. A pumping mechanism is provided on the side wall of the quantitative tube 16.

[0040] like Figure 2 and Figure 6 As shown, the adjustment mechanism includes a positioning ring 19. The positioning ring 19 is sleeved on the side wall of the crossbar 17. A stop bar 24 is fixedly connected to the outer wall of the positioning ring 19. A screw hole 34 is opened on the outer wall of the positioning ring 19. A screw 20 is installed in the screw hole 34. One end of the screw 20 extends into the positioning ring 19 and contacts the crossbar 17.

[0041] like Figure 2 and Figure 6 As shown, the pumping mechanism includes a second check valve 26. The second check valve 26 is installed at one end of the metering tube 16. A first check valve 25 is installed on the side wall of the metering tube 16 near the second check valve 26. A liquid storage tank 27 is provided on the top of the mounting plate 1. A water delivery pipe 28 is installed on one side of the liquid storage tank 27. One end of the water delivery pipe 28 is fixedly connected to the second check valve 26. A spray pipe 30 is provided inside the mounting plate 1. Both ends of the spray pipe 30 pass through the mounting plate 1. A connecting pipe 29 is fixedly connected to one end of the spray pipe 30. One end of the connecting pipe 29 is fixedly connected to the first check valve 25. Several evenly distributed nozzles are installed on the side wall of the spray pipe 30.

[0042] The quantitative dispensing mechanism draws the flotation agent from the storage tank 27 into the quantitative tube 16. The quantitative tube 16 is made of transparent material and has a scale on its outer wall, allowing for a clear view of the amount drawn each time. The first one-way valve 25 and the second one-way valve 26 have opposite check directions, which is necessary to draw the flotation agent and push it into the spray pipe 30. To accommodate the flotation of more types of coal, the amount of flotation agent drawn into the quantitative tube 16 each time can be adjusted by adjusting the position of the positioning ring 19. The adjustment is convenient and the operation is simple.

[0043] The support block 3 is fixedly connected to the first slider on both sides. The inner wall of the rectangular opening 2 is provided with a first groove that matches the first slider. The first slider and the first groove can limit the support block 3, so that the support block 3 will not fall or rotate during the left and right sliding process, thus playing the role of limiting and supporting.

[0044] In addition, the rectangular plate 21 and the crossbar 17 are respectively fixedly connected to the side opposite to the mounting plate 1 with a second slider. The top of the mounting plate 1 is provided with a second slide groove that matches the second slider. The second slider and the second slide groove can limit the rectangular plate 21 and the crossbar 17, so that the crossbar 17 will not rotate during use, which can effectively improve the stability of use and keep the stop bar 24 in a horizontal state.

[0045] The working principle or general working process of this utility model is as follows: In use, firstly, the flotation agent is placed in the storage tank 27. After pouring in an appropriate amount of flotation agent, the coal slurry can be injected into the flotation tank 15. Next, the motor 11 is started by connecting an external power source. The motor 11 drives the reciprocating screw 9 to rotate. Simultaneously, the rotation of the reciprocating screw 9 drives the slide tube 10 and the support block 3 to move back and forth. At this time, the support block 3 will drive the transmission tube 4 and the aeration shell 5 to move back and forth. Because the gear 12 meshes with the rack 14, when the transmission tube 4 moves back and forth, the gear 12 will drive the transmission tube 4 to rotate in both directions, thereby driving the stirring blade 7 and the stirring rod 8 to rotate in both directions. This can fully stir multiple areas of the flotation tank 15, so that the coal slurry in the flotation tank 15 is fully mixed.

[0046] When the support block 3 moves to the left, after reaching a certain position, the push plate 33 will contact the stop rod 24. As the support block 3 continues to move to the left, it pushes the stop rod 24 and the crossbar 17 to move to the left, stretching the tension spring 23. Simultaneously, the crossbar 17 drives the piston plate 18 to move to the left, creating a negative pressure in the metering tube 16. At this time, the first one-way valve 25 closes, while the second one-way valve 26 opens. The negative pressure allows the flotation reagent in the storage tank 27 to enter the metering tube 16 through the water supply pipe 28, achieving the function of extracting the flotation reagent. When the support block 3 moves to the left to its limit position, it will return to the right. At this time, the stop rod 24 loses the pushing force of the push plate 33, and simultaneously... The tension spring 23 contracts, causing the rectangular plate 21 and the crossbar 17 to move to the right. This pushes the flotation agent in the metering tube 16 through the piston plate 18, increasing the internal pressure of the metering tube 16. This pressure causes the second one-way valve 26 to close and the first one-way valve 25 to open. At this time, as the tension spring 23 contracts, it pulls the crossbar 17, allowing the flotation agent in the metering tube 16 to enter the spray pipe 30 through the first one-way valve 25 and the connecting pipe 29. The nozzle on the spray pipe 30 then sprays the flotation agent onto the coal slurry, where it is thoroughly mixed by the stirring rod 8 and the stirring blade 7. This process is repeated to continuously and quantitatively add the flotation agent and to mix the coal slurry and the flotation agent.

[0047] To better mix the flotation agent with the coal slurry, the aeration pump 31 can be started by an external control power supply. The aeration pump 31 delivers gas through the air pipe 32 to the transmission pipe 4, and then into the aeration shell 5. The gas is sprayed out through the aeration holes 6 to form aeration, which can accelerate the mixing speed of the flotation agent and the coal slurry.

[0048] The dosage of flotation reagent can be adjusted as needed. First, loosen the screw 20, then adjust the position of the positioning ring 19 to the left or right. When the positioning ring 19 moves to the left, the distance the stop rod 24 is pushed by the push plate 33 is shorter. Conversely, when the positioning ring 19 moves to the right, the distance the stop rod 24 is pushed by the push plate 33 is longer. This allows for adjusting the flotation reagent dosage. After adjustment, tighten the screw 20 to fix the position of the positioning ring 19. By adjusting the position of the positioning ring 19, the dosage of flotation reagent drawn into the metering tube 16 each time can be adjusted, effectively improving ease of use.

[0049] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
