DETAILED DESCRIPTION

[0026] Please refer to Figs. 1-3 The present application provides a technical scheme: an oil field water quality filtering and separating equipment, which comprises a filter tank 1 and a filter basket 2, and the left side of the filter tank 1 is horizontally connected with a water inlet pipe 11 which is in communication with the inside of the filter tank 1, so that the water to be filtered enters the filter tank 1 from the water inlet pipe 11, and the water inlet pipe 11 is evenly provided with a plurality of water inlet pipes 11, and the water flows from different water inlet pipes 11 to form a relatively uniform rightward flow state.

[0027] The right side of the filter tank 1 is horizontally connected with a water outlet pipe 12 which is in communication with the inside of the filter tank 1, so that the water filtered finally is discharged from the water outlet pipe 12 on the right side, and the water outlet pipe 12 is provided with at least three water outlet pipes 12, which are the same as the above purpose, and the water flows from different water outlet pipes 12 to form a relatively uniform rightward flow state.

[0028] The filter basket 2 is arranged on the right side of the filter tank 1, and the left side of the filter basket 2 is provided with an opening. When the water flows to the right side, the oil dirt and floating impurities will flow to the right side and be collected and intercepted in the filter basket 2 due to the oil dirt and floating impurities floating on the water surface. The filter tank 1 is fixed with the filter cotton 14 at the bottom of the filter basket 2. The water flow also passes through the filter cotton 14 from below and flows out from the drain pipe 12. The water flow is filtered by the filter cotton 14 between the filter tank 1 and the filter basket 2, and finally flows out from the drain pipe 12 for use.

[0029] Through the arrangement of the above scheme, the water outlet is arranged on the lower right side, and the water flow is easy to flow from the upper left side to the lower right side, so that the flow speed on the water surface is slow, and it is not easy to carry the oil dirt and floating impurities to flow to the right side to be collected. In order to solve the problem, the upper side surface of the filter tank 1 on one side of the filter basket 2 is provided with a water outlet cover 13 which is in communication with the inside of the filter tank 1. The water outlet cover 13 is in communication with the inside of the filter tank 1 through the left side long strip-shaped opening. A water pump 4 is also installed on the side of the filter tank 1. The inlet of the water pump 4 is connected to the water outlet cover 13 on the right side of the filter tank 1 through a backwater pipe 41. The water on the upper layer enters the water outlet cover 13 through the strip-shaped opening, and is extracted by the water pump 4 and flows into the filter tank 1 on the left side again through the backwater pipe 41. The water flow speed on the water surface is formed, which is beneficial to carry the oil dirt and floating impurities to flow to the direction of the filter basket 2.

[0030] The filter basket 2 is locked in the right side of the filter tank 1 in the following manner. The two sides of the filter basket 2 are fixed with support plates 21, and the upper surface of the filter tank 1 at the support plates 21 is provided with support grooves 3. The support plates 21 are supported in the support grooves 3 to support and limit the filter basket 2. The surfaces of the support plates 21 are also fixed with handles 211 on both sides. The support plates 21 and the filter basket 2 can be lifted by the handles 211 to clean the oil dirt and floating impurities collected in the filter basket 2, and the filter cotton 14 can be taken out for cleaning or replacement. A blocking net 22 is also vertically fixed on one side of the bottom of the filter basket 2. The height of the blocking net 22 is less than half the height of the filter basket 2. When the filter basket 2 is lifted to clean the impurities in the filter tank 1, the blocking net 22 is not easy to cause the collected impurities to leak out.

[0031] In addition, a plurality of upper insertion rods 23 are vertically fixed on the bottom surface of the filter basket 2, and a plurality of lower insertion rods 15 are vertically fixed on the bottom of the filter tank 1 below the filter cotton 14. The upper insertion rods 23 and the lower insertion rods 15 are inserted into the filter cotton 14 to achieve the locking purpose of the filter cotton 14.

[0032] In use, the water pipe to be filtered and separated is connected to different water inlet pipes 11 through multiple pipe channels, ensuring that the water to be treated can flow uniformly from left to right. At the same time, the water pump 4 is started to draw water from the right side to the left side of the filter tank 1 through the water outlet cover 13 and the water return pipe 41 in a small flow state. The water in the filter tank 1 also flows to the right side of the drain pipe 12. Due to the oil and impurities floating on the water surface, under the flow action of the water pump 4, the oil and impurities or floating impurities will flow to the right side and be collected and intercepted in the filter basket 2. In the process of water flowing to the drain pipe 12, the water will be filtered by the filter cotton 14 between the filter tank 1 and the filter basket 2, and finally discharged from the drain pipe 12 for use. During use, the filter work is stopped regularly, the handle 211 is lifted to lift the support plate 21 and the filter basket 2, the oil and impurities collected in the filter basket 2 are cleaned, and the filter cotton 14 can be taken out for cleaning or replacement.
