Description

Technical Field

[0001] The invention relates to the technical field of smoke recovery, and in particular to a cold rolling mill emulsion smoke recovery device and a use method thereof. Background Art

[0002] The cold rolling mill is a new type of steel bar cold rolling processing equipment. It uses an electric motor to drag the steel bar, and uses the load-bearing roller and working roller of the cold rolling mill to apply force to the two sides of the steel bar. By changing the size of the gap between the two rollers, the purpose of rolling cold-rolled ribbed steel bars of different diameters is achieved. During the operation of the cold rolling unit, emulsion (rolling oil and water mixed in proportion) will be used to cool the rollers and strip steel. This process will produce a large amount of emulsion smoke. In order to improve the working environment, a fan is required to collect and purify the emulsion smoke and discharge it outdoors.

[0003] The patent with announcement number CN217070167U discloses a cold rolling mill emulsion smoke recovery device, which is equipped with a lower cover and an upper cover at the outlet of the emulsion smoke discharge chimney. The upper cover has an automatic fan extending to the inside of the lower cover. When the water vapor containing the emulsion passes through the fan blades, the fan blades can be driven to rotate, and the water vapor in the emulsion smoke is separated. The inner wall of the upper cover body condenses the water again, and the gas is discharged from the air flow channel. The main pollutants containing a large amount of water flow back to the bottom of the chimney along the inner wall of the chimney, and then recovered from the bottom to the sewage treatment workshop for pollution-free treatment. The device only separates water and gas through the rotation of the fan blades, and the operating efficiency is low. A large amount of smoke will be carried in the gas and discharged directly from the outlet, causing pollution. Summary of the invention

[0036] The mixing element 15 includes an inner gear ring 17 fixedly mounted on the inner wall of the tank body 2, and a gear block 18 meshing with the inner gear ring 17 is rotatably connected to the bottom of the connecting pipe 12.

[0038] See also Figure 1-Figure 8 The method for using the cold rolling mill emulsion smoke recovery device shown in the figure comprises the following steps:

[0039] S1. The emulsion is loaded into the bottom of the tank 2, and the emulsion smoke is input into the tank 2 through the conveying mechanism;

[0040] S2. The emulsion smoke is pressurized and input into the emulsion liquid for absorption and mixing through the recovery mechanism;

[0041] S3. The gas overflowing from the emulsion is guided by the guiding mechanism to extend the gas delivery path, and the emulsion in the tank 2 is pumped to the top position and then sprayed downward by the circulation mechanism to fully absorb the emulsion smoke in the gas;

[0042] S4. The emulsion smoke is continuously recovered at the bottom of the tank 2, and the gas is discharged through the conveying mechanism.

[0043] In this embodiment, the emulsion smoke to be recycled is input through the air inlet pipe 3, the drive motor 10 is started to drive the drive shaft 9 to rotate, and the drive shaft 9 drives the fixed plate 8 to make the rotating cylinder 7 rotate together. At this time, the rotating cylinder 7 drives the guide groove 25 to make the pressure plate 24 rotate synchronously. Since the fixed cylinder 22 is fixed on the fixed frame 21 and is in a stationary state, the pressure plate 24 rotates in the reciprocating thread groove 23 to achieve reciprocating lifting operation. When the pressure plate 24 moves downward, the space between it and the fixed plate 8 increases, and the smoke on the upper side of the fixed plate 8 can be drawn into the area between the fixed plate 8 and the pressure plate 24 through the one-way valve 14 in the first through hole 13. On the contrary, when the pressure plate 24 moves upward, the smoke in this area is compressed and discharged into the connecting pipe 12 through the one-way valve 14 in the connecting pipe 12, and enters the storage chamber 19 in the gear block 18, and finally output to the emulsion liquid at the bottom of the tank body 2 through the second through hole 20 for mixed absorption.

[0044] It is worth noting that: in the process of rotating the cylinder 7 driving the connecting tube 12 to rotate, the gear block 18 rolls on the inner gear ring 17, changing the position of the second through hole 20, so that the smoke discharged from the second through hole 20 can be evenly distributed to various positions in the emulsion solution, thereby improving the absorption efficiency. At the same time, as the connecting tube 12 rotates, the stirring function of the emulsion solution can be synchronously realized, so that the emulsion is more evenly distributed.

[0045] The air overflowing from the emulsion solution will float upward and be guided and transported through the guiding mechanism to extend the gas transport path. At the same time, the emulsion in the tank body 2 is pumped to the top position through the circulation mechanism and then sprayed downward to fully absorb the emulsion smoke in the gas. The absorbed gas is discharged through the exhaust pipe 4, and the emulsion solution at the bottom of the tank body 2 can flow into the drain pipe 5 through the connecting groove 6. The emulsion solution at the bottom can be discharged and collected by opening the drain pipe 5.

[0046] Example 2

[0047] See also Figure 2-Figure 5 Embodiment 2 is described. This embodiment further describes Embodiment 1. The circulation mechanism shown in the figure includes a first filter screen 29 fixedly mounted on the bottom end of the inner wall of the tank body 2. A circulation pipe 30 is connected to the side of the tank body 2. A delivery pump 31 is provided on the circulation pipe 30. An annular pipe 32 is rotatably connected inside the tank body 2. The upper end of the circulation pipe 30 is connected to the annular pipe 32. A plurality of third through holes 33 are evenly arranged on the bottom of the annular pipe 32. An auxiliary part 34 is provided on the driving shaft 9 for driving the annular pipe 32 to rotate and spray and assist in aerosol delivery and filtration.

[0048] The auxiliary component 34 includes a wind wheel 35 fixedly mounted on the top of the driving shaft 9. The upper and lower sides of the wind wheel 35 are respectively connected to the air intake pipe 3 and the rotating cylinder 7. The upper side of the wind wheel 35 is rotatably connected to the air intake pipe 3. The outer wall of the wind wheel 35 is evenly and fixedly connected with multiple groups of connecting rods 36 fixedly connected to the annular tube 32. Multiple groups of second filters 37 are evenly and fixedly connected between the wind wheel 35 and the annular tube 32.

[0049] In this embodiment, the emulsion solution filtered by the first filter screen 29 is pumped into the circulation pipe 30 by the delivery pump 31, discharged into the annular tube 32 at the top, and discharged downward through the third through hole 33 for spraying, thereby performing secondary absorption and recovery of the rising gas. During the rotation of the drive shaft 9, the wind wheel 35 is driven to rotate, thereby assisting the smoke in the intake pipe 3 to be transported to the rotating cylinder 7. At the same time, the annular tube 32 is driven to rotate by the connecting rod 36 to change the position of the third through hole 33, so that the spraying range is more comprehensive. The gas absorbed by the spraying passes through the second filter screen 37 and is discharged into the exhaust pipe 4 for discharge. The second filter screen 37 has a large number of interwoven fibers, and the fibers can be made of glass fiber mesh interlaced and woven. These fibers will not absorb water inside, but can form water droplets by absorbing the aerosol on the surface and then drip down to the bottom of the tank body 2, thereby achieving the purpose of recovering the aerosol again.

[0050] Example 3

[0051] See also Figure 2-Figure 5 Embodiment 3 is described. This embodiment further describes Embodiment 1. The guiding mechanism shown in the figure includes a plurality of first slope rings 27 fixedly mounted on the outer wall of the rotating cylinder 7. A plurality of second slope rings 28 are evenly and fixedly connected to the inner wall of the tank body 2. The first slope rings 27 and the second slope rings 28 are alternately arranged.

[0052] In this embodiment, through multiple groups of alternatingly distributed first slope rings 27 and second slope rings 28, the path of the gas rise can be made to be curved. At the same time, the emulsion liquid flowing downward from the upper side will flow downward through the upper surface slopes of the first slope rings 27 and the second slope rings 28, forming a water curtain at the edge. In the process of the gas passing through the water curtain, the emulsion smoke mixed in the gas is absorbed again. The emulsion smoke rises in this way and passes through multiple water curtains to reach the position of the second filter 37, which greatly improves the efficiency of emulsion smoke recovery.
