Description

Technical Field

[0001] This utility model relates to the field of papermaking white water recycling technology, and in particular to a papermaking white water recycling device. Background Technology

[0002] Papermaking white water (hereinafter referred to as white water) is wastewater from the papermaking process. It originates from the papermaking process in the papermaking workshop. White water mainly contains fine fibers, fillers, coatings and dissolved wood components, as well as added sizing agents, wet strength agents, preservatives, etc. It is mainly composed of insoluble COD and has low biodegradability.

[0003] White water contains a large amount of fine fibers and other fine solid particles suspended in the air. Existing white water recycling and treatment devices are ineffective in treating impurities when processing large amounts of white water, resulting in low efficiency and easy clogging of the filter screen, which hinders filtration, affects equipment use, and is troublesome to clean, wasting manpower.

[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 4As shown, a papermaking white water recycling device of the present invention includes a shell 4, a filtering mechanism 5, a cleaning mechanism and an inlet mechanism. The filtering mechanism 5 is disposed inside the shell 4. The cleaning mechanism is disposed in the middle of the filtering mechanism 5 and connected to the shell 4. One side of the inlet mechanism is disposed at the lower part of the cleaning mechanism, and the other side of the inlet mechanism is disposed outside the shell 4. A drain outlet 9 is disposed at the lower part of the shell 4.

[0026] The filtration mechanism 5 includes a drive assembly, a turntable 505, an annular filter screen 503, and a rotating ring 504. The turntable 505 is rotatably connected to one side of the outer casing 4. One end of the annular filter screen 503 is connected to the turntable 505, and the other end of the annular filter screen 503 is rotatably connected to the other side of the outer casing 4 through the rotating ring 504. The annular filter screen 503 is disposed inside the outer casing 4. The drive assembly is drivenly connected to the turntable 505, and the cleaning mechanism is disposed in the middle of the annular filter screen 503.

[0027] The cleaning mechanism includes a partition 11 and a scraper 12. The partition 11 is disposed in the middle of the annular filter screen 503 and is fixedly connected to the other side of the outer casing 4. One end of the partition 11 is provided with a gap 6 with one side of the annular filter screen 503, and the other end of the partition 11 is in contact with the other side of the annular filter screen 503. The scraper 12 is inclinedly disposed on the upper part of the partition 11, and the lower part of the scraper 12 is connected to the upper part of the other end of the partition 11. The upper part of the scraper 12 is movably connected to the annular filter screen 503. One side of the inlet mechanism is connected to the lower part of the partition 11.

[0028] The working principle of this utility model is as follows: In actual production and use, when it is necessary to filter and recycle white water, the inlet mechanism can be operated to introduce white water into the housing 4 and discharge it into the middle of the annular filter screen 503. Subsequently, the particulate matter in the white water is retained on the inner side of the annular filter screen 503. The filtered water passes through the annular filter screen 503 and is discharged and collected from the drain outlet 9. During the white water filtration process, the drive component can be operated to drive the annular filter screen 503 to rotate through the turntable 505. While the annular filter screen 503 is rotating, the fibers and solid particles adhering to the annular filter screen 503 are rotated through the gap 6 to the top of the partition plate 11. When passing through the scraper 12, the scraper 12 scrapes the impurities on the annular filter screen 503 onto the partition plate 11, so that the part of the annular filter screen 503 that has passed through the scraper 12 is cleaned. Then the cleaned annular filter screen 503 continues to move to the bottom of the inlet mechanism for better filtration.

[0029] Furthermore, the drive assembly includes a rotation drive 502, a first gear 506, and a second gear 501. The first gear 506 is sleeved on the outside of the turntable 505, and the second gear 501 is rotatably connected to the outside of the housing 4. The first gear 506 and the second gear 501 mesh with each other, and the rotation drive 502 is drivenly connected to the second gear 501.

[0030] As can be seen from the above description, when it is necessary to clean the annular filter screen 503 located at the lower part of the outer casing 4, the rotating drive component 502 can be operated, so that the rotating drive component 502 drives the turntable 505 to rotate through the second gear 501. The turntable 505 drives the annular filter screen 503 that needs to be cleaned to the scraper 12 position through the gap 6 for cleaning. The turntable 505 can also move the cleaned annular filter screen 503 to the lower part of the outer casing 4 for continued filtration, thereby enhancing the continuity of the white water recovery process.

[0031] Furthermore, the inlet mechanism includes a liquid pump 2, a mounting buckle 10, an inlet tube, a main flow tube 7, and several branch tubes 8. The main flow tube 7 is detachably connected to the lower part of the partition 11 through the mounting buckle 10. The other side of the outer shell 4 is provided with a mounting hole adapted to the inlet tube. The inlet tube passes through the mounting hole. One end of the inlet tube is connected to the main flow tube 7. The other end of the inlet tube is provided with the liquid pump 2. The liquid pump 2 is located outside the outer shell 4. Several branch tubes 8 are provided at the lower part of the main flow tube 7.

[0032] As can be seen from the above description, when it is necessary to recycle and filter white water, the pump 2 can be run to introduce white water into the main pipe 7 through the inlet pipe, and then injected into the inner side of the annular filter screen 503 through the diversion pipe 8 for filtration.

[0033] Furthermore, it also includes a sealing door 1, and a slag discharge port is provided on the other side of the outer shell 4. The slag discharge port is located above the partition 11, and the sealing door 1 is detachably connected to the slag discharge port.

[0034] As can be seen from the above description, it is advantageous for operators to open the slag discharge port by opening the sealing door 1, so that the fiber and other particulate matter collected on the partition 11 can be discharged outside the device through the slag discharge port for collection.

[0035] Furthermore, it also includes support feet 3, and several support feet 3 are fixedly connected to the bottom of the outer shell 4.

[0036] As can be seen from the above description, this is conducive to more stable operation of the device and facilitates the collection of filtered water from the drain outlet 9.

[0037] Furthermore, it also includes a PLC controller, which is electrically connected to the filtering mechanism 5 and the inlet mechanism respectively.

[0038] As can be seen from the above description, it is beneficial to adjust the parameters of the papermaking white water recovery device through the PLC controller, and to make it more convenient for operators to operate the papermaking white water recovery device. Example 1
