Description

Technical Field

[0001] The invention relates to the technical field of cooling water treatment, and in particular to a circulating cooling water treatment system for a steel plant. Background Art

[0002] The steel plant circulating cooling water treatment system refers to a system used to treat and recycle cooling water generated during the production process of the steel plant. The system removes impurities, hardness and microorganisms in the cooling water through physical, chemical or biological methods, such as filtration, softening, sterilization, etc., to maintain the water quality of the cooling water so that it meets the standards for reuse and ensures that it can be efficiently and stably recycled in various cooling links of the steel plant. The treated cooling water is sent to the cooling equipment again to complete a cycle. In this process, the cooling water continuously absorbs and takes away the heat generated by the equipment. By absorbing the heat generated by the equipment, the high-temperature medium is cooled to prevent the equipment from overheating and damage, and to extend the service life of the equipment.

The stirring component includes an air outlet pipe and a hollow shaft that are connected to each other internally; the upper part of the hollow shaft is rotatably connected to the top of the treatment box, and the lower part of the hollow shaft extends into the treatment box; the circumferential array of air outlet pipes of the hollow shaft has an air outlet arranged along the air outlet pipe, and the secondary steam in the continuous expansion container is discharged from the air outlet to drive the stirring component to rotate, without the need to set up additional driving equipment, the structure is simple, and the cost is low; the boiler sewage after cooling and pressure reduction is introduced into the treatment box, and the dosing component includes a drug inlet pipe, which runs through the treatment box; the outer end of the drug inlet pipe is connected to the reagent box, and the inner end is provided with a driven gear; the hollow shaft is provided with a driving gear meshing with the driven gear, and the driving gear drives the drug inlet pipe to rotate circumferentially to add drugs, and the drugs are diffused in the sewage in the treatment box to the surroundings, which is conducive to the rapid and uniform treatment of boiler sewage.

[0004] The existing steel mill circulating cooling water treatment system has effectively integrated the sewage filtration, cooling and dosing anti-scaling processes when treating circulating cooling water. The dosing device is a key link, which prevents pipe scaling by adding specific medicine into the cooling water. However, when preparing the medicine, the height and angle of the stirring blades of the dosing device in this system are fixed. This limitation results in the stirring process being able to effectively mix only a specific height layer in the medicine, and it is difficult to achieve uniform and rapid fusion of the entire medicine. Therefore, when faced with medicines that require highly mixed and homogenized, the device has to extend the stirring time to ensure the mixing effect, which inevitably affects the overall efficiency and timeliness of the steel mill's circulating cooling water treatment. In response to the above problems, the present invention document proposes a steel mill circulating cooling water treatment system. Summary of the invention

[0019] Beneficial effects:

[0020] 1. The circulating cooling water treatment system of the steel plant not only supports multiple positioning shafts through a fixing ring arranged on the outside of the driving shaft and multiple flexibly rotatable mounting shafts embedded inside the fixing ring, but also enables multiple positioning shafts and multiple stirring blades to realize orbital and rotational motions in the dosing barrel driven by the driving shaft through the positioning wheels at the ends of each mounting shaft and the tooth grooves on the arc plate.

[0021] 2. The circulating cooling water treatment system of the steel plant is equipped with a material holding frame on the outside of the driving shaft, and cooperates with multiple resistance blocks on the outside of the material holding frame and a toggle rod on the inner wall of the dosing barrel. When the driving shaft drives the material holding frame to rotate, the resistance block will periodically contact and separate with the toggle rod. This interaction causes the powder in the material holding frame to be subjected to uniform thrust, thereby achieving uniform dispersion of the powder in the dosing barrel, avoiding the accumulation or wrapping of the powder in the dosing barrel, ensuring that the powder can enter the medicine solution evenly and stably, so that the medicine solution can quickly mix with it to form a uniform mixed liquid, thereby improving the efficiency and effect of the medicine solution mixing.

When the material frame 16 rotates, it will drive multiple resistance blocks 39 on the outside to rotate. In conjunction with the toggle rod 38 on one side of the inner wall of the dosing barrel 3, the material frame 16 can vibrate when rotating, so that the powder in the material frame 16 can be thoroughly and evenly sprinkled in the dosing barrel 3 through the discharge hole 35;

[0050] When the medicine is mixed and stirred, the driving shaft 6 will not only drive the multiple stirring blades 25 to rotate, but also drive the fixing rings 8 to rotate through the multiple fixing rods 7. The fixing rings 8 will drive the multiple installation shafts 22 to rotate. The multiple installation shafts 22 will respectively drive the multiple positioning shafts 10 to rotate. The multiple positioning shafts 10 will respectively drive the multiple stirring blades 26 to rotate, so that the medicine can be mixed and stirred. The rotation of the multiple positioning shafts 10 will also drive the multiple adjustment shafts 28 to rotate through the multiple limiting plates 29 at the same time. The multiple adjustment shafts 28 will respectively drive the multiple fixed shafts 30 to rotate through the multiple universal joints 31. The multiple fixed shafts 30 will respectively drive the multiple positioning wheels 14 to rotate. In conjunction with the tooth grooves at the bottom end of the arc plate 13, the multiple positioning shafts 10 can also rotate during the revolution. At the same time, in conjunction with the arc plate 13 set in an arc shape, the multiple positioning wheels 14 can be driven to move up and down. The multiple positioning wheels 14 will respectively drive the multiple positioning shafts 10 to rotate, thereby driving the multiple positioning shafts 10 to swing up and down, expanding the range of mixing and stirring the medicine, thereby making the efficiency and uniformity of the medicine mixing better.

[0051] When the medicine is in the mixing process, the pump body 40 can be started, and the pump body 40 will pump the medicine at the bottom of the medicine-dosing barrel 3 into the hose 42 and the water injection pipe 43 through the water delivery pipe 41. When the medicine enters the water injection pipe 43, it will fall into the material holding frame 16 through multiple water injection holes 47 and multiple drainage holes 46, which can not only rinse the residual medicine powder in the material holding frame 16, but also lift the thicker medicine deposited at the bottom of the medicine-dosing barrel 3 to the upper end of the medicine-dosing barrel 3, thereby promoting the comprehensive flow and mixing of the medicine in the medicine-dosing barrel 3. Then, the electric push rod 45 is started, and the output end of the electric push rod 45 will drive the water injection pipe 43 to move, so that the upper water inlet 51 can be aligned with the water inlet 50, so that the medicine can enter the annular tube 48 and flow to the inner wall of the medicine-dosing barrel 3 through multiple water outlet holes 49, so that the medicine powder adhering to the inner wall of the medicine-dosing barrel 3 can be cleaned, thereby avoiding the waste and accumulation of medicine powder.
