screen for dam form seal hermetically type easily sludge exhaust

摘要

The present invention relates to a dam-type closed screen for removing sludge in the form of an OIL mass contained in a solution when the steel plate is washed using an alkaline solution and a brush roll, and a dam-type closed screen in which the screen tank (12) A rectangular glass window 18 is fixed by a bolt 20 by means of a glass fixing frame 19 so that a work situation can be visually checked at the upper end and a triangular screen 13 A screen guide plate 15 is installed in the width direction in which the screen is mounted so that the solution flowing down is always flowed down in a constant amount and the sludge flowing down between the screen 13 and the screen guide plate 15 A cleaning nozzle 16 is mounted so as not to be sandwiched by the nozzle 13 and a nozzle 13 is provided at the rear end of the screen 13 to clean the sludge on the surface of the screen during operation. A tank discharge pipe 10 is installed after a level gauge 11 capable of measuring the tank level is installed and a screen high pressure nozzle 30 is mounted on the screen 31. An upper portion and a lower portion A sludge cleaning plate shaft 14 for guiding the sludge to the lower end while being moved is installed and a sludge cleaning blade 28 is mounted on the axis of the sludge cleaning plate shaft 14. The sludge cleaning plate shaft 14 is moved up and down on both sides of the screen tank 12 And the cylinder 39 is mounted on a cylinder fixing member 38 formed in the screen tank and a shaft wheel 43 is mounted on the end of the shaft 14 to fix the motor 39 A motor wheel 42 mounted on the motor shaft and a tension retaining spring 47 mounted on a side surface of the screw gear box 33, a tension wheel 44 connected to the motor wheel 42, Is mounted with a belt (48) connected to the tensioning wheel (44), and a screw The screw 21 of the shaft 22 is mounted on the shaft bearing 23 and the screw gear box 33 is mounted on the shaft 22 and the motor 34 is mounted on the motor fixing member 35 And a sludge discharge port 24 and a sludge box 26 for discharging the sludge 25 are installed on the opposite side of the sludge tank 25 so that sludge can be discharged easily. It is possible to effectively remove nylon from the sludge in the form of an OIL mass and the brush roll that has been dropped during the operation and to discharge the product out of use while the screen is being cleaned. In addition, with this effect, it is possible to further improve the cleanliness of the surface of the plated strip and produce a high quality product.
