[0002] Pulp is a slurry made from a mixture of cellulose and water, commonly used to make paper and cardboard. Cellulose, the main component of plant cell walls, can be extracted from plant fiber materials such as wood, bamboo, and waste paper.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5The utility model provides a technical solution: a water filtering device for a pulp dewatering machine that is convenient for accelerating water filtering, comprising: a mounting base 1, a water filtering bin 2, a first squeezing roller 3, a first gear 4, a second squeezing roller 5, a second gear 6, a transmission box 7, a water pipe 8, a nozzle 9, a vibration plate 10, an electric push rod 11, a scraper 12, a guide rod 13, a rotating rod 14, an eccentric wheel 15, a motor 16, a drying bin 17, a fan 18, and a heater 19.

[0028] First, as attached Figure 1 , Attachment Figure 4 and attached Figure 5 As shown in , when the device is used to filter water from pulp, the pulp is first poured into the interior of the water filter bin 2 through the top of the water filter bin 2, and then three groups of first squeezing rollers 3 are arranged about the horizontal line of the water filter bin 2, and three groups of second squeezing rollers 5 are also arranged about the horizontal line of the water filter bin 2. At the same time, the second gear 6 on the second squeezing roller 5 is meshed with the first gear 4 on the first squeezing roller 3, and then the second squeezing roller 5 is driven to rotate through the output end of the transmission box 7, so that the transmission box 7 drives the second squeezing roller 5 to rotate in the opposite direction through the second gear 6. At the same time, the second gear 6 is meshed with the first gear 4, so that the second gear 6 drives the first squeezing roller 3 to rotate in the opposite direction through the first gear 4, and then the spacing between the first squeezing rollers 3 is greater than the spacing between the second squeezing rollers 5, so that the pulp entering the water filter bin 2 is first squeezed by the first squeezing roller 3, and at the same time, the pulp squeezed by the first squeezing roller 3 is squeezed again by the second squeezing roller 5 on the pulp squeezed by the first squeezing roller 3, so that the water in the pulp can be quickly separated by squeezing;

[0029] As attached Figure 1 , Attachment Figure 2 and attached Figure 3As shown in the figure, when the pulp is squeezed by the second squeezing roller 5, the squeezed pulp falls to the surface of the vibration plate 10, and then is slidably connected to the inner wall of the water filter bin 2 through the vibration plate 10. At the same time, the guide rod 13 at the bottom of the vibration plate 10 is arranged in a corresponding state with the eccentric wheel 15 on the rod body of the rotating rod 14, and then a synchronous pulley is fixedly installed on the rod body at the rear end of the rotating rod 14, so that the synchronous pulleys on the rotating rods 14 at the left and right ends of the water filter bin 2 are connected together through a belt sleeve, and then the output end of the motor 16 is fixedly connected to the rear end of the left rotating rod 14 in the water filter bin 2, so that the motor 16 drives the rotating rods at the left and right ends of the water filter bin 2 through the cooperation between the synchronous pulley and the belt. The movable rod 14 rotates synchronously, thereby causing the rotating rod 14 to drive the eccentric wheel 15 to rotate. Since the eccentric wheel 15 corresponds to the guide rod 13, and the eccentric wheels 15 at the left and right ends of the water filter bin 2 are arranged in a staggered state, when the left eccentric wheel 15 in the water filter bin 2 fits with the guide rod 13, the eccentric wheel 15 drives the vibration plate 10 to form a lifting structure. At the same time, when the left eccentric wheel 15 in the water filter bin 2 descends, the right eccentric wheel 15 in the water filter bin 2 rises, thereby causing the right eccentric wheel 15 in the water filter bin 2 to fit with the guide rod 13, thereby causing the vibration plate 10 to slide against the inner wall of the water filter bin 2 again, and then through the up and down vibration of the vibration plate 10, the squeezed pulp can be separated by vibration.

[0030] As attached Figure 1 and attached Figure 3 As shown in , after the pulp on the surface of the vibration plate 10 is separated by vibration, the electric push rods 11 at the front and rear ends of the vibration plate 10 can be started. First, the output end of the front electric push rod 11 in the vibration plate 10 drives the scraper 12 to slide on the surface of the vibration plate 10, thereby pushing the pulp on the surface of the vibration plate 10 through the left scraper 12 in the vibration plate 10 to the right scraper 12. At the same time, the right scraper 12 is in the middle position of the surface of the vibration plate 10, and then the scraper 12 can be driven to slide on the surface of the vibration plate 10 by the output end of the rear electric push rod 11 in the vibration plate 10. Since the scraper 12 and the drying chamber 17 are arranged in a corresponding state, and the drying chamber 1 7 is arranged in a connected state with the water filter bin 2, and the pulp on the surface of the vibration plate 10 is pushed to the inside of the drying bin 17 by the scraper 12, and then the fan 18 and the heater 19 can be started to generate heat by the heater 19. At the same time, the wind generated by the fan 18 also blows the wind generated by the heater 19 into the inside of the drying bin 17, and then the pulp inside the drying bin 17 is dried, thereby accelerating the drying speed of the pulp by the heat source. After the pulp is filtered, it can be connected to the water pipe 8 through an external water pipe, and then the nozzle 9 is arranged in an array state on the pipe body of the water pipe 8, and the internal components of the water filter bin 2 are flushed by the nozzle 9.
