Description

Technical Field

[0001] The invention relates to the technical field of water purification equipment, and in particular to a metallurgical turbid water cyclone filter. Background Art

[0002] Metallurgical turbid water has always been a long-standing problem that has troubled metallurgical enterprises. Turbid water is in direct contact with the cooling object, and a large amount of iron oxide particles, metal dust and lubricating grease are brought into the water, forming an oil-containing turbid water system. In fact, it is a complex three-phase mixed system of water, solid (metal dust) and oil. Its characteristics are high concentration of iron oxide, large particle size and high oil content. The key to treating this wastewater is oil removal. Metallurgical turbid water is prone to form "oil sludge" with high viscosity. The oil sludge is very easy to adhere to pipes and water-using equipment, causing pipes and water-using equipment (such as nozzles) to be blocked, affecting normal production and product quality. In severe cases, the workshop will be shut down. The oil sludge adheres to the filter material of the filter equipment and blocks the filter material. It is not easy to remove, so that the filter equipment cannot operate normally. Abnormal operation of water treatment equipment will cause the circulating water quality to continue to deteriorate, causing the circulation system to be in a vicious cycle. In order to maintain normal production, some manufacturers will discharge all or part of the oily wastewater, which seriously pollutes the water body and wastes precious water resources. To this end, various steel companies and design and research departments are researching and exploring new methods of oil and pollution removal to improve the quality of turbid circulating water in the metallurgical industry.

[0003] The existing metallurgical turbid water filtering equipment is not perfect and has the following problems:

[0004] First, common filtering equipment cannot perform circulating filtration, has technical problems such as long filtration time and low efficiency.

[0031] like Figure 1As shown, a metallurgical turbid water cyclone filter comprises a sealed tank body 1, a filtering mechanism 2, a water inlet pipe 3, and a clean water pipe 4. The water inlet pipe 3 is connected to the inside of the sealed tank body 1. The filtering mechanism 2 comprises a water distributor 5, a first air distributor 61, a second air distributor 62, a third air distributor 63, and a filter baffle 7. The water distributor 5 is composed of an inlet pipe 51 and an outlet pipe 52. The inlet pipe 51 is connected to the inlet pipe 3. Eight outlet pipes 52 are provided. The eight outlet pipes 52 are installed around the inlet pipe 51. , each outlet pipe 52 is provided with a water discharge hole, and its function is that water enters the water inlet pipe 3, and the water flows through the water inlet pipe 51 and then is divided into eight outlet pipes 52, and is discharged into the sealed tank body 1 through the outlet holes provided on the eight outlet pipes 52, so as to stir the sewage in the sealed tank body 1. The first air distributor 61 is arranged below the water distributor 5, and the first air distributor 61 is composed of eight first outlet pipes (64) connected in a surrounding manner, and the first outlet pipe (64) is provided with an outlet hole, and the second air distributor 62 is arranged at the first outlet pipe (64). The first air distributor 61 is disposed below the second air distributor 62, which is composed of eight second air outlet pipes (65) connected in a circumferential manner. The first air distributor 61 and the second air distributor 62 are connected to a first air inlet pipe 83. The first air inlet pipe 83 can distribute the external airflow to the first air distributor 61 and the second air distributor 62. The gas in the first air distributor 61 and the second air distributor 62 is discharged through the air outlet holes, so that the water in the sealed tank body 1 generates a swirling flow. The filter baffle 7 is installed below the second air distributor 62. 7 divides the entire sealed tank body 1 into two parts, the space above the filter baffle 7 is the filter chamber 9, and the lower part of the filter baffle 7 is the water purification chamber 8. The filter baffle 7 is provided with a fiber ball 71, and the impurities in the sewage are filtered by the fiber ball 71, and the filtered water flows into the space below the filter baffle 7. The third air distributor 63 is arranged below the filter baffle 7, and the third air distributor 63 is composed of a second air inlet pipe 92 and a third air outlet pipe 66. The second air inlet pipe 92 is connected to the outer side of the sealed tank body 1, as shown in FIG. Figure 5 As shown, eight third air outlet pipes 66 are provided, and the eight third air outlet pipes 66 are arranged in a ring shape and are connected to the second air inlet pipe. The third air outlet pipes 66 are provided with air outlet holes, and the air outlet holes face upward. The function of the third air outlet pipes 66 is to respectively introduce the airflow into the eight third air outlet pipes 66 through the second air inlet pipe 92, and to guide the air upward through the air outlet holes on the third air outlet pipes 66, so that the water flowing into the clean water chamber 8 is blown back to the filter chamber 9 for repeated filtration to ensure a more thorough filtration effect. The water after multiple cleanings flows into the clean water chamber 8, and finally the filtered water is discharged through the clean water pipe 4.

[0032] Preferably, Figure 3As shown, the eight first air outlet pipes 64 are provided with counterclockwise arranged air outlet holes, whose function is that the gas discharged from the clockwise arranged air outlet holes causes the sewage in the purification chamber to generate counterclockwise vortex flow, prompting the fiber balls 71 to filter impurities in the sewage.

[0033] Preferably, Figure 4 As shown, the eight second air outlet pipes 65 are provided with clockwise arranged air outlet holes, whose function is that the clockwise arranged air outlet holes discharge gas through the air outlet holes to make the sewage in the purification chamber produce clockwise vortex, prompting the fiber balls 71 to filter impurities in the sewage. At the same time, the second air distributor 62 cooperates with the first air distributor 61 to make the sewage stirred more fully and filter the impurities in the sewage on the fiber balls.

[0034] Preferably, the height of the clean water pipe 4 is set in the middle of the clean water chamber 8. Its function is that the clean water after filtration contains a small amount of dirt. After a period of sedimentation, the dirt is at the bottom of the clean water chamber 8, and the clean water is in the middle and upper part of the clean water chamber 8. By setting the height of the clean water pipe 4 in the middle of the clean water chamber 8, the water flowing out of the clean water pipe 4 is precipitated clean water.

[0035] Preferably, a sewage outlet 82 is further provided at the bottom of the water purification chamber 8 , and the sewage outlet 82 is arranged at the bottom of the water purification chamber 8 . Its function is to discharge the dirt through the sewage outlet 82 when too much dirt is deposited at the bottom of the water purification chamber 8 .

[0036] Preferably, a backwash water inlet 81 and a backwash drain 91 are also provided in the water purification chamber 8. Water is injected through the backwash water inlet 81 to clean the sealed tank body 1, and the backwash water is discharged from the equipment through the backwash drain 91. When backwashing is performed, the water inlet and the water purification pipe 4 are first closed, and then the backwash water inlet 81 is opened to allow water to flow into the sealed tank body 1. The third air distributor 63 is opened, and the compressed gas blown out from the third air distributor 63 is used to blow up the fiber ball 71 to a fluffy state. The first air inlet pipe 83 is opened, and compressed air is blown out simultaneously from the second air distributor 62 and the first air distributor 61 through the first air inlet pipe 83 to cause the fiber ball 71 to rotate, rub, and collide in the sealed tank body 1. Finally, the backwash water is discharged through the backwash drain 91 to complete the backwashing.

[0037] Preferably, the backwash cycle is 8 to 12 hours. After 8 to 12 hours of filtration, a certain amount of dirt is accumulated inside the equipment, and backwashing is required to clean the inside to ensure the filtering effect of the equipment.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
