After the filter cloth 90 is washed by the washing nozzle 70, the residual copper powder on the filter cloth 90 can be basically washed away and fall into the sedimentation tank 82.

After the filter cloth 90 passes through the roller scrapers 60 and the washing spray head 70, the copper powder on the filter cloth 90 can basically fall off and fall into the sedimentation tank 82. Because the density of the copper powder is greater than that of water, the copper powder automatically sinks after falling into the water. In order to collect copper powder in the sedimentation tank 82, a support screen 87 is arranged at the middle lower part of the sedimentation tank 82, and a second filter screen 88 is arranged on the support screen 87. The support screen 87 is spaced parallel to the bottom surface of the settling tank 82. The supporting net 87 is used for supporting the second filter 88, and may be made of a metal material, which has a certain supporting strength. The second filter 88 is used to filter the copper powder so that the copper powder in the precipitation tank 82 may be precipitated on the second filter 88. The second filter 88 is detachably connected to the support screen 87, and the specific structure thereof can refer to the prior art, and this embodiment does not limit it.

Further, a first drain hole 89 is provided at the bottom of the sedimentation tank 82, a second drain hole 810 is provided at the bottom of the clean water tank 83, and openable covers are provided at the first drain hole 89 and the second drain hole 810, respectively.

From this, just formed the utility model discloses a copper powder and filter cloth recovery unit of SCR continuous casting and rolling production line. When the filter cloth rolling device is used, the right side of the filter cloth 90 faces upwards, the filter cloth 90 passes through the upper part of the first guide roller 10, the filter cloth 90 is led to the lower part of the third guide roller 30 from the side, far away from the third guide roller 30, of the first guide roller 10, then the filter cloth 90 passes through the lower part of the fourth guide roller 40, the filter cloth 90 is led to the upper part of the second guide roller 20 from the position between the fourth guide roller 40 and the second guide roller 20, and then the filter cloth 90 is led to the rolling device 50. Therefore, the filter cloth 90 originally faces upwards, and when entering the sedimentation tank 82, the filter cloth is turned over to face downwards, so that the copper powder on the face falls off. During operation, the first guide roller 10, the second guide roller 20, the third guide roller 30 and the fourth guide roller 40 can rotate continuously to tension the filter cloth 90, so that the filter cloth 90 passes through the scraping of the roller scraper 60 in the sedimentation tank 82 and the washing of the washing nozzle 70 in sequence, and the copper powder falls off to clean the filter cloth 90. Wherein, because the filter cloth 90 is immersed in water when the filter cloth 90 passes through the roller scraper 60, copper powder on the filter cloth 90 is more easily separated out, and the copper powder on the filter cloth 90 can basically fall off by the scraping of the roller scraper 60, and the filter cloth can be further washed clean by the following washing nozzle 70. The filter cloth 90 after being cleaned is automatically rolled by the rolling device 50, thereby being beneficial to recycling the filter cloth 90. When the filter cloth 90 is cleaned in the sedimentation basin 82, the copper powder on the filter cloth 90 falls into the sedimentation basin 82 and is deposited on the second filter screen 88. The first drain hole 89 and the second drain hole 810 are then periodically opened to drain the water in the recovery tank 80. After the water in the recovery tank 80 is drained, the copper powder is collected on the second filter screen 88, and at the moment, the copper powder can be recovered from the second filter screen 88, so that the copper powder can be recycled.

When in use, the device can be intermittently started according to the copper powder collection degree on the filter cloth 90 in the emulsion tank. When the copper powder on the filter cloth 90 is too much and the emulsion is difficult to circulate, the copper powder and filter cloth recovery device of the SCR continuous casting and rolling production line can be opened, so that the filter cloth 90 is automatically pulled to automatically clean through the sedimentation tank 82. When the device is used for the first time, a certain amount of clean water can be injected into the recovery tank 80. When the device is in operation, the water pump 85 can pump clean water from the clean water reservoir 83 to flush the filter cloth 90. After entering the sedimentation tank 82, the washing water is circulated through the first filter screen 84 above the partition plate 81. When the water in the sedimentation tank 82 reaches a certain height, the clear water in the upper layer of the sedimentation tank 82 flows into the clear water tank 83, so that the water can be recycled. When the first filter 84 is blocked by copper powder and the liquid circulation is seriously affected, the first drain hole 89 and the second drain hole 810 can be opened for draining, the water in the recovery tank 80 is completely drained, then the first filter 84 is replaced or the first filter 84 is cleaned, and the copper powder on the second filter 88 is collected.
