Description

Technical Field

[0001] The utility model relates to the technical field of dehydration devices, in particular to a cellulose dehydration device. Background Art

[0002] Cellulose fiber, also known as artificial fiber, mainly includes viscose fiber, acetate fiber and cuprammonium fiber, etc. It is obtained by reshaping the cellulose molecules of natural materials such as cotton linter, wood, bamboo, bagasse and reed through certain process treatment methods. In the existing cellulose fiber production process, a dehydration device is often required to dehydrate the cellulose fiber. For example, the patent with publication number CN219797745U discloses a dehydrator for cellulose fiber production, including a fixed bottom plate, a hydraulic rod is fixedly mounted on the fixed bottom plate, the top end of the hydraulic rod is fixedly connected to a mounting top plate, a servo motor is fixedly connected to the mounting top plate, a first circular gear is fixedly connected to the output shaft of the servo motor, a second circular gear is meshedly connected to the first circular gear, and a feed pipe is fixedly connected to the second circular gear. The device utilizes a flexible scraper on the top of the support rod to automatically drop the cellulose fibers stuck to the inner wall of the fixed frame into the first collecting frame, thereby effectively preventing the cellulose fibers from sticking to the inner wall of the fixed frame. However, some cellulose may stick directly to the scraper through the scraper.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a cellulose dehydration device, comprising an outer cylinder 1, an inner cylinder 2 is rotatably fitted inside the outer cylinder 1, a plurality of filter holes 15 are opened on the circumference of the inner cylinder 2, a filter bag 3 is installed in the inner cylinder 2, a first fixed block 10 and a plurality of second fixed blocks 11 are installed between the inner cylinder 2 and the filter bag 3, a pressure ring 13 is installed in the inner cylinder 2, the pressure ring 13 corresponds to the filter bag 3, a cover plate 8 is rotatably fitted on the upper side of the outer cylinder 1, and the cover plate 8 corresponds to the second fixed blocks 11.

[0023] In this embodiment, a support frame 4 is fixed to the circumferential side of the outer cylinder 1, a support plate 7 is slidably fitted on the support frame 4, a motor 6 is fixed on the support plate 7, an output end of the motor 6 is fixedly connected to a cover plate 8, a plurality of electric cylinders 5 are fixed to the support frame 4, an output end of the electric cylinder 5 is fixedly connected to the support plate 7, a plurality of slots 9 are provided in the cover plate 8, and the slots 9 correspond to the second fixed block 11.

[0024] Specifically, when centrifugal dehydration is required, the filter bag 3 is fixed in the inner drum 2 by the first fixing block 10 and the second fixing block 11, and then cellulose is poured into the filter bag 3, and the electric cylinder 5 is started, so that the electric cylinder 5 drives the support plate 7 to move downward, thereby driving the cover plate 8 to move downward until the second fixing block 11 enters the slot 9, and then the motor 6 is started, so that the motor 6 drives the cover plate 8 to rotate, thereby driving the inner drum 2 to rotate, and centrifugal dehydration can be performed.

[0025] The bottom of the filter bag 3 is fixedly connected to the bottom of the inner tube 2 via a first fixing block 10 , and both the first fixing block 10 and the second fixing block 11 are threadedly matched with the inner tube 2 .

[0026] Specifically, when it is necessary to fix the filter bag 3 inside the inner tube 2, the second fixing block 11 can be passed through the filter bag 3 and threadedly fixed to the side of the inner tube 2, and then the first fixing block 10 can be passed through the filter bag 3 and threadedly fixed to the bottom of the inner tube 2. In order to facilitate disassembly, a fixing rod can be fixedly installed on the first fixing block 10, and the installation and disassembly of the first fixing block 10 can be achieved by rotating the fixing rod. The position of one end of the first fixing rod close to the top of the inner tube 2 can facilitate the installation and disassembly of the first fixing block 10.

[0027] The inner tube 2 is provided with a plurality of fixing grooves 12 , a plurality of clamping blocks 14 are fixed on the pressure ring 13 , and the clamping blocks 14 are fixed in the fixing grooves 12 by bolts. A water outlet 16 is provided at the bottom of the outer tube 1 .

[0028] Specifically, the pressure ring 13 can be fixed to the top of the inner tube 2 by bolts, so that when the filter bag 3 is pulled out, the filter bag 3 will pass through the pressure ring 13. Since the cellulose is accumulated at the bottom of the filter bag 3, the pressure ring 13 will squeeze the filter bag 3, thereby realizing extrusion dehydration. Combined with centrifugal dehydration, it can ensure that the dehydration is more thorough. Regardless of centrifugal dehydration or extrusion dehydration, the waste water generated by dehydration will flow out from the water outlet 16 to prevent water accumulation in the outer tube 1 and ensure the dehydration effect.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
