Description

Technical Field

[0001] The utility model relates to the technical field of papermaking equipment, in particular to an environment-friendly papermaking equipment capable of recycling sewage. Background Technique

[0002] Papermaking wastewater refers to the wastewater generated in the pulping and papermaking process, including pulping cooking waste liquid, washing wastewater, bleaching wastewater, paper machine white water, etc. Papermaking wastewater has a complex composition and poor biodegradability. It belongs to industrial wastewater that is relatively difficult to treat and is one of the main industrial pollution sources at present. Currently, the papermaking industry mostly uses straw, wood pulp, etc. as papermaking raw materials. The pulping and papermaking production generally consists of processes such as pulping, washing pulp, bleaching, and papermaking.

[0003] The application number is CN202021274866.9, which discloses an environment-friendly papermaking equipment capable of recycling sewage, including a headbox. A workbench is installed below the headbox, and a sewage recovery tank is installed below the workbench. In this environment-friendly papermaking equipment capable of recycling sewage, through the setting of the sewage recovery tank, the industrial water used by the papermaking equipment flows into the workbench through the headbox and flows through the conveyor belt outside the tensioning roller below the workbench. The used water flows down to the sewage recovery tank below the workbench, thereby collecting the industrial water. The sewage is filtered through a filter plate inside the sewage recovery tank. When in use, the filter plate divides the sewage into two parts, and the water suction pipe below the water pump sucks the filtered clean water, and the extracted water is discharged into the water tank, and the outer surface of the paper is sprayed through the electric spray head on one side, so as to carry out the processing work. The sewage is reused, effectively reducing resource consumption and improving environmental protection.

[0004] During the papermaking process, there are usually certain paper scraps in the sewage. When the device filters and treats the sewage, a filter screen is used to treat the paper scraps in the sewage. During the filtering process, the paper scraps will accumulate on the filter screen, causing the filter screen to be blocked, affecting the filtering effect and rate. Content of the Utility Model

[0039] During use, start the motor 202, open the bottom valve of the paper machine 12, and the sewage will enter the filter box 201 through the feed pipe 207, and then fall onto the first filter plate 204. The paper impurities will stay on the first filter plate 204. At the same time, the operation of the motor 202 will drive the rotating rod 203 to rotate clockwise. The rotation of the rotating rod 203 drives the first filter plate 204 to rotate. The rotation of the first filter plate 204 drives the paper impurities to rotate. When it rotates to the impurity outlet 208, the paper will enter the extrusion box 301 through the recovery port 209 due to gravity and centrifugal force. Some impurities may fall onto the second filter plate 205 due to the impact force of the water flow.

At the same time, the rotating rod 203 will drive the first pulley 206 to rotate. The first pulley 206 drives the second pulley 303 to rotate through the belt. The second pulley 303 drives the connecting rod 302 to rotate. The connecting rod 302 drives the turntable 304 to rotate. The turntable 304 drives the bottom end of the pull rod 305 to rotate, so that the top end of the pull rod 305 moves up and down. The movement of the pull rod 305 drives the fixed rod 306 to move. The fixed rod 306 drives the push rod 307 to move. The movement of the push rod 307 drives the sleeve 308 to move. The sleeve 308 drives the pressing plate 311 to move. When the pressing plate 311 contacts the paper debris and the push rod 307 continues to move downward, at this time, the push rod 307 will push the limit piece 309 downward to compress the spring 310. The reaction of the spring 310 applies a downward force to the pressing plate 311, so as to squeeze the paper debris entering the extrusion box 301 and remove the sewage adsorbed by the paper debris. The squeezed water flows into 201 through the filter holes 313 and the recovery port 209, further reducing water resource waste. Because the spring 310 has a certain elastic range, it can squeeze the paper debris with a certain thickness. And the diameter of the first pulley 206 is six times that of the second pulley 303, and six first filter plates 204 are provided. Therefore, when the first pulley 206 rotates one-sixth of a circle, the turntable 304 rotates one circle, so as to ensure that when the paper impurities enter the extrusion box 301, the pressing plate 311 is always located at the top of the extrusion box 301. The rotation of the first pulley 206 drives the third turntable 402 to rotate. The rotation of the water inlet pipe 403 makes the water pump 401 operate, so as to pump the filtered water into the paper machine 12 through the turntable 304 and then through the water outlet pipe 404 for recycling.
