The inside of the cylinder 43 is provided with a filter assembly comprising a circular filter plate 52, and an annular receiving groove 51 is fixedly arranged at the edge of the filter plate 52, namely, the filter plate 52 is sleeved in the annular receiving groove 51.
The trough body of the receiving trough 51 is semicircular.
A vertical discharging pipe 56 is fixedly arranged at the bottom of the receiving groove 51.
As shown in fig. 9, the outer wall of the receiving groove 51, which is far from the filter plate 52, is fixedly connected with the inner wall of the cylinder 43, so that the receiving groove 51 and the filter plate 52 are integrated and fixed in the cylinder 43.
The middle part of the filter plate 52 is provided with a rotatable central shaft 54 through a bearing, the top of the central shaft 54 is fixedly provided with an L-shaped spraying pipe 46 through a connecting seat 59, the vertical part of the spraying pipe 46 is in dynamic sealing connection with the third pipeline 6, and the length of the horizontal part is equal to the diameter of the filter plate 52.
The connecting seat 59 is fixedly connected to the connection of the vertical portion and the horizontal portion of the spout 46.
As shown in fig. 13, the side of the horizontal portion of the spray pipe 46 facing the filter plate 52 is provided with a spout 69, and the width of the spout 69 gradually increases from one end of the horizontal portion near the vertical portion to one end of the horizontal portion distant from the vertical portion. The progressively wider spouts allow for a more uniform spray of fiber slurry on the filter plates 52 as the pressure of the fiber slurry is progressively lower after entering the horizontal section from the vertical section.
A first scraper 53, a squeeze roller 50, and a second scraper 55 are radially and sequentially installed on the central shaft 54, and a horizontal portion of the spray pipe 46 is located between the first scraper 53 and the second scraper 55.
As shown in fig. 9 and 10, the second scraper 55 has an arc shape, a first end of which is connected with the central shaft 54 by bolts, and a second end of which is flush with the edge of the filter plate 52, and a bottom of the second scraper 55 abuts against the top of the filter plate 52. The concave side of the second blade 55 faces the side away from the direction of rotation of the second blade 55.
The roll body 68 of the squeeze roll 50 is free to rotate with a first gap between the roll body 68 and the filter plate 52. The length of the roller bodies 68 is matched to the size of the filter plates 52, i.e., the length of the roller bodies 68 is equal to the difference between the outside diameter of the filter plates 52 and the outside diameter of the central shaft 54.
The first scraper 53 is bolted to the central shaft 54 at a first end and is flush with the edge of the filter plate 52 at a second end.
A second gap is left between the bottom of the first scraper 53 and the filter plate 52. The height of the second gap is equal to or greater than the height of the first gap, preferably greater than the height of the first gap.
The second belt wheel 49 is fixedly installed on the vertical portion of the spraying pipe 46, the second belt wheel 49 is connected with the first belt wheel 45 through a first belt, the first belt wheel 45 is fixedly installed at the output end of the second motor 44, and the second motor 44 is fixedly installed on the outer wall of the cylinder 43.
When coarse filtration is performed, the second motor 44 drives the second belt pulley 49 to rotate, and since the second belt pulley 49 is fixed on the spray pipe 46, the spray pipe 46 is fixed on the central shaft 54 through the connecting seat 59. Therefore, the central shaft 54 is rotated by the second motor 44, and the spray pipe 46, the squeeze roller 50, the first scraper 53, and the second scraper 55 are simultaneously rotated.
The spray pipe 46 sprays the fiber slurry on the filter sheet 52, and is then scraped by the first scraper 53 to form a uniform material layer, and is then pressed by the pressing roller 50 to remove a part of the moisture, which finally flows out from the drain opening. The arcuate second scraper 55 then scrapes the fibrous material into the receiving bin 51. Compared with the existing similar equipment, the structure can remove more water in the fiber slurry, and the treatment process is more continuous.
In order to convey the fibrous material in the receiving chute 51 into the discharge pipe 56, as shown in fig. 10 and 12, a horizontal mounting plate 63 is fixedly mounted on the connecting seat 59, a vertical connecting rod 65 is fixedly mounted at the end of the mounting plate 63, and a scraper 60 matched with the receiving chute 51 is fixedly mounted at the bottom of the connecting rod 65.
As the central shaft 54 rotates, the flights 60 rotate to deliver fibrous material to the discharge tube 56.
In order to prevent the material from being blocked in the material discharging pipe 56, a packing auger 57 is arranged in the material discharging pipe 56, a third belt wheel 58 is fixedly arranged at the bottom end of the packing auger 57, the third belt wheel 58 is connected with a fourth belt wheel through a second belt, and the fourth belt wheel is fixedly arranged at the output end of the third motor 48. The third motor 48 is fixedly mounted to a second motor mount which is fixedly mounted to the ground.
The side wall of the discharge pipe 56 is fixedly provided with a discharge port 47, and the discharge port 47 is positioned at the bottom of the side wall of the discharge pipe 56. The discharge opening 47 is connected to the filter press 3 via a first line 2.
In order to keep the stability of the spray pipe 46 in rotation, a cover is mounted on the top of the cylinder 43, and the vertical portion of the spray pipe 46 passes through the cover and is rotatably fitted with the cover through a bearing.
The structure of the first scraper 53 is shown in fig. 11, and includes a handle 62 having one end connected to the central shaft 54 by a bolt, a cutter body 61 is fixedly mounted on the bottom of the handle 62 by a bolt, and an inclined surface facing the filter plate 52 is disposed on the cutter body 61 and is located at one side of the advancing direction of the cutter body 61.
The squeeze roller 50 has a structure as shown in fig. 12, and comprises a roller body 68 rotatably mounted on a roller 67, wherein rod seats 66 are respectively provided at both ends of the roller 67, the tops of the two rod seats 66 are fixedly connected with the first ends of corresponding spring rods 64, and the second ends of the spring rods 64 are fixedly connected with the bottom of a mounting plate 63.
In the present embodiment, the rod seat 66 has a quadrangular prism structure, and a receiving groove for receiving the rod seat 66 is provided on the central shaft 54.
Due to the presence of the spring rods 64, the roller body 68 is able to accommodate a certain thickness of fibrous material and to squeeze it out of water. Also because roll body 68 is free to rotate, roll body 68 does not push material as does first blade 53 and second blade 55.
The spring rod 64 is shown in fig. 14, and comprises a sleeve 70, wherein the top of the sleeve 70 is fixedly connected with a mounting plate 63, a sliding rod 72 is sleeved in the sleeve 70, the top of the sliding rod 72 is positioned in the sleeve 70 and is fixedly provided with a clamping plate 74, the bottom of the sleeve 70 is fixedly provided with a clamping ring 73 matched with the clamping plate 74, and the clamping ring 73 can prevent the clamping plate 74 from falling out of the sleeve 70.
A spring 71 is mounted between the catch plate 74 and the top wall of the sleeve 70. The bottom of the slide bar 72 is fixedly connected with the corresponding bar seat 66.
Of course, the coarse filter 1 may be a prior art device such as a soymilk filter.
When the device is used, a material to be treated enters a first bending sieve 19 from a ninth pipeline 20 to be screened for the first time, the formed fiber slurry enters a third bin body 10 to be cleaned, the cleaned fiber slurry is pumped into a second bending sieve 21 to be screened for the second time, the fiber slurry generated by the second screening enters a first bin body 7 to be cached, the fiber slurry in the first bin body 7 is pumped into a coarse filter 1 to remove part of water, then the fiber slurry is discharged into a filter press 3 to press the water, and finally the fiber slurry is sent into a dryer 5 to be dried, so that a finished product is obtained.
