Description

Technical Field

[0001] The utility model relates to the technical field of acetate fiber production, in particular to an elevator for acetate fiber. Background Art

[0002] Cellulose acetate is a thermoplastic resin obtained by esterification using acetic acid as a solvent and acetic anhydride as an acetylating agent in the presence of a catalyst. It is the earliest commercially produced and continuously developed cellulose organic acid ester among cellulose derivatives. As a porous membrane material, cellulose acetate has the characteristics of high selectivity, high water permeability, and simple processing.

[0003] During the production of acetate fiber, an elevator is generally required. Most elevators are equipped with an observation port through which workers can clean the interior. However, the opening and closing of the existing observation port is cumbersome. In addition, when the existing elevator is in operation, acetate fiber is in powder form and easily spills when entering the elevator hopper and falls into the interior of the elevator. The elevator can only be stopped for cleaning and recycling, which not only wastes money but also affects work efficiency. Utility Model Content

[0023] In this embodiment, an ascending air duct 10 is fixedly installed at one end of the two-way air duct 9, and one end of the ascending air duct 10 is connected to the bottom of the ascending wind head 11. A transverse air duct 13 is fixedly installed at the other end of the two-way air duct 9, and one end of the transverse air duct 13 is connected to one side of the transverse wind head 14. An observation port is opened on one side of the lifting shell 2 to facilitate cleaning of the interior of the elevator.

[0024] In this embodiment, an opening and closing base 17 is fixedly installed on the inner side of the observation port, an opening and closing plate 18 is rotatably installed on one side of the opening and closing base 17, an opening and closing shell 19 is fixedly installed on one side of the opening and closing plate 18, a mounting sleeve 21 is fixedly installed on one side of the opening and closing shell 19, and an electric push rod 20 is fixedly installed on the inner side of the mounting sleeve 21.

[0025] In this embodiment, a fixed shell 28 is fixedly installed on the inner side of the opening and closing shell 19, and two sliding metal blocks 25 are slidably installed on the inner side of the fixed shell 28. A fixed metal block 27 is fixedly installed on the side where the two sliding metal blocks 25 are away from each other. A fixing hole is opened on one side of the lifting shell 2, and two grooves are provided on the inner side of the fixing hole. The two fixed metal blocks 27 are respectively adapted to the corresponding grooves.

[0026] In this embodiment, a sliding groove 26 is provided on one side of the two sliding metal blocks 25, and a sliding bar 24 is slidably installed on the inner side of the two sliding grooves 26. The same extruded metal block 23 is fixedly installed on one side of the two sliding bars 24, and an extrusion rod 22 is fixedly installed on one side of the extruded metal block 23 to facilitate the extruded metal block 23 to drive the two sliding bars 24 to move.

[0027] In this embodiment, the extruded metal block 23 is slidably installed on the inner side of the fixed shell 28. A sliding hole is opened on one side of the fixed shell 28. The extrusion rod 22 slides on the inner side of the sliding hole. The output end of the electric push rod 20 is connected to the extrusion rod 22, so that the electric push rod 20 can drive the extruded metal block 23 to move.

[0028] Working principle: The staff starts the machine through the control panel 3, and then pours the acetate fiber raw material into the feed pipe 6. After passing through the feed pipe 6, the raw material falls into multiple lifting hoppers 16 by inertia, and then moves upward with the conveyor belt 15. When it reaches the designated position, it is thrown through the discharge port to the designated position. However, the raw material is prone to spillage during transportation through the elevator. At this time, the spilled raw material slides to the left side of the fixed base 1 through the slope plate 7 by inertia. At this time, the blower 8 is started, and the wind force generated passes through the two-way air duct 9. Part of the wind force enters the rising air duct 10, and reaches the rising wind head 11 through the rising air duct 10. At this time, the raw material sliding down by inertia reaches the barrier net 12, and the wind force blows out through the rising wind head 11 to make the raw material rise. At this time, the other part of the wind force enters the transverse air duct 13 and passes through the transverse wind The head 14 blows out to blow the rising raw materials into the feed pipe 6, reducing the waste of raw materials. When the production is completed, the staff needs to clean the inside of the elevator through the observation port. The staff starts the electric push rod 20 through the control panel 3. The electric push rod 20 starts to drive the extrusion rod 22 to retract. The retraction of the extrusion rod 22 drives the extrusion metal block 23 to move. The movement of the extrusion metal block 23 drives the two sliding bars 24 to move. The movement of the two sliding bars 24 drives the corresponding sliding metal blocks 25 to retract. The retraction of the two sliding metal blocks 25 drives the corresponding fixed metal blocks 27 to retract. The two fixed metal blocks 27 retract into the inner side of the fixed shell 28, releasing the limit on the opening and closing plate 18. At this time, the staff can quickly and easily open the opening and closing plate 18 through the handle on the surface of the opening and closing plate 18 to clean the inside of the elevator.

[0029] The technical progress achieved by the present invention over the prior art is that the improved observation port is more convenient to open and close, and no complicated procedures are required for opening and closing, thereby improving the convenience of the device. In addition, through the provided mechanism, the acetate fiber spilled inside can be recovered and transported again through the lifting hopper 16, which greatly reduces material waste and improves work efficiency.
