Technical Field

[0001] This utility model relates to the field of water used in sintering production, and in particular to a wastewater utilization device based on sintering production. Background Technology

[0002] The sintering process control is basically divided into process links such as batching, mixing, ignition, sintering, ventilation, crushing, cooling, and screening. Among them, the mixing operation is further divided into three process steps: adding water, mixing and granulation. Moreover, "air, water and carbon" are the three essential elements of sintering production.

[0003] The mixing and water addition process in sintering production is the core and key step. On average, 0.5 tons of water are needed per ton of sinter.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Example 1, as Figure 1 and Figure 2 As shown, a wastewater utilization device based on sintering production includes a wastewater component 1, a water supply component 2, and a filter component 3. The water supply component 2 is used to supply clean water to the wastewater component 1 and the filter component 3 respectively. The wastewater component 1 generates wastewater, and the filter component 3 filters the wastewater.

[0033] Wastewater assembly 1 includes a mixer 11, a purifier 12, and a wastewater pipe 13. The dust outlet of the mixer 11 is connected to the dust suction end of the purifier 12. The mixture of materials in the mixer 11 will generate dust, which enters the purifier 12. The liquid inlet of the wastewater pipe 13 is connected to the interior of the purifier 12.

[0034] The water supply assembly 2 includes a water storage tank 20, a first water outlet pipe 21, and a first water pump 23. The water storage tank 20 is used to store clean water. The two ends of the first water outlet pipe 21 are connected to the purifier 12 and the water storage tank 20, respectively. The first water pump 23 is installed on the first water outlet pipe 21. When the dust stored in the purifier 12 needs to be discharged, the first water pump 23 is turned on. The clean water comes out from the first water outlet pipe 21 and sprays into the purifier 12. The dust and the clean water mix to form wastewater. The clean water sprayed out from the first water outlet pipe 21 is used to clean the inside of the purifier 12. The wastewater is discharged through the wastewater pipe 13.

[0035] The water supply assembly 2 also includes a second water outlet pipe 22 and a second water pump 24. The two ends of the second water outlet pipe 22 are connected to the third filter tank 33 and the water storage tank 20, respectively. The second water pump 24 is installed on the second water outlet pipe 22. The third filter tank 33 is filled with clean water, which is a mixture of filtered water and clean water. When the liquid stored in the third filter tank 33 is insufficient, the second water pump 24 is turned on, and the second water outlet pipe 22 supplies clean water to the third filter tank 33, so that the small amount of fine dust impurities in the third filter tank 33 are diluted.

[0036] The filter assembly 3 includes a first filter tank 31, a second filter tank 32, and a third filter tank 33. The outlet end of the wastewater pipe 13 is located in the first filter tank 31. Wastewater flows out of the wastewater pipe 13 and enters the first filter tank 31, where it settles first. The second filter tank 32 is located between the first filter tank 31 and the third filter tank 33. The outlet end of the second filter tank 32 is higher than the inlet end of the third filter tank 33, and the outlet end of the first filter tank 31 is higher than the inlet end of the second filter tank 32. After settling in the first filter tank 31, some dust and impurities in the wastewater settle at the bottom of the first filter tank 31. The relatively clean wastewater overflows from the first filter tank 31 and flows into the second filter tank 32, where it settles again. The relatively clean wastewater after settling becomes filtered water, which overflows from the second filter tank 32 and flows into the third filter tank 33, where it is stored for later use.

[0037] In this example, the first filter tank 31, the second filter tank 32, and the third filter tank 33 are all cubic in shape.

[0038] The filter assembly 3 includes a water injection pump 34 and a water injection pipe 35. The two ends of the water injection pipe 35 are connected to the third filter tank 33 and the mixer 11, respectively. The water injection pump 34 is installed on the water injection pipe 35. When clean water needs to be injected into the mixer 11, the water injection pump 34 is turned on and the water injection pipe 35 injects clean water into the mixer 11.

[0039] The third filter tank 33 is also equipped with a steam pipe 4, which is connected to a steam source. The steam pipe 4 supplies steam to the third filter tank 33, and the steam heats the liquid in the third filter tank 33. The steam outlet of the steam pipe 4 is located at the bottom of the third filter tank 33, so the steam flows upward and the liquid in the third filter tank 33 will churn. There are also a small amount of fine dust impurities in the third filter tank 33. The churning of the liquid prevents the fine dust impurities from settling. These small amounts of fine dust impurities flow back to the mixer 11 from the water injection pipe 35 along with the liquid.

[0040] The filter assembly 3 also includes a first agitator 311, a first drain pipe 312, and a first drain pump 313. The first agitator 311 is installed inside the first filter tank 31, the first drain pipe 312 is connected to the first filter tank 31, and the first drain pump 313 is installed on the first drain pipe 312. When the first filter tank 31 needs to be cleaned, because a lot of dust and impurities have settled in the first filter tank 31, the first agitator 311 is turned on. The first agitator 311 stirs the sediment and liquid in the first filter tank 31, so that the sediment and liquid mix to form sewage. At the same time, the first drain pump 313 is started so that the sewage in the first filter tank 31 is discharged from the first drain pipe 312.

[0041] The filter assembly 3 also includes a second agitator 321, a second drain pipe 322, and a second drain pump 323. The second agitator 321 is installed inside the second filter tank 32, and the second drain pipe 322 is connected to the second filter tank 32. The second drain pump 323 is installed on the second drain pipe 322. When the second filter tank 32 needs to be cleaned, because a lot of dust and impurities have settled inside the second filter tank 32, the second agitator 321 is turned on. The second agitator 321 stirs the sediment and liquid inside the second filter tank 32, causing the sediment and liquid to mix and form sewage. At the same time, the second drain pump 323 is turned on, so that the sewage inside the second filter tank 32 is discharged from the second drain pipe 322.

[0042] The first filter tank 31 has a first outlet 314 on its wall and a first filter screen 5 at the first outlet 314. Wastewater settles in the first filter tank 31, and then the relatively clean wastewater passes through the first filter screen 5 and flows into the second filter tank 32.

[0043] The second filter tank 32 has a second outlet 324 on its wall and a second filter screen 6 at the second outlet 324. The mesh size of the second filter screen 6 is smaller than that of the first filter screen 5. The relatively clean wastewater settles in the second filter tank 32 and then flows out of the second filter screen 6. The filtered water enters the first filter tank 31.

[0044] The first filter 5 filters out large dust particles and impurities, while the second filter 6 filters out small dust particles and impurities.

[0045] Example 2, as Figure 3 and Figure 4 As shown, unlike Embodiment 1, the first filter tank 31, the second filter tank 32 and the third filter tank 33 are all configured as hollow columns. The first filter tank 31 is located inside the second filter tank 32, and the second filter tank 32 is located inside the third filter tank 33. Wastewater overflows from the first filter tank 31 into the second filter tank 32, and then overflows from the second filter tank 32 into the third filter tank 33.
