Description

Technical Field

[0001] The utility model relates to the field of feeding devices, in particular to a spiral feeding device for mica paper production. Background Art

[0002] The mica paper production process primarily involves seven steps: crushing, grading, pulping, papermaking, forming, pressing, and drying. These four steps are well-established in mica paper production, making crushing, grading, and pulping the mica paper the most crucial parts of the entire mica paper production process. The quality of these three steps directly impacts the quality and performance of the finished mica paper. After the mica raw materials are crushed, the shredded material is poured into a grading and screening device to facilitate the next step.

[0003] In the prior art, after the mica crushed material is poured into the elevator, the spiral blades of the elevator rotate to lift the material to a high place and then drop it. During this process, a lot of powder and dust will fall due to the friction between the materials and between the materials and the spiral blades. This powder and dust will pass through the gap between the blades and the inner wall of the elevator and fall and accumulate at the bottom of the elevator. Therefore, it is necessary to open the elevator frequently for discharge and cleaning, otherwise it will cause blockage and friction affecting the blades, reducing the service life.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0027] Example 1:

[0028] A spiral feeding device for mica paper production includes a device body 1, in which a spiral roller 3 is rotatably installed, an upper end of the outer wall of the device body 1 is provided with a discharge port 5 connected to the interior of the device body 1, and a lower end of the outer wall of the device body 1 is provided with a feed port 4 connected to the interior of the device body 1. A dust block 6 adapted to the inner wall of the device body 1 is rotatably installed at a point on the bottom of the outer wall of the device body 1 away from the feed port 4, and dust holes 8 are arranged at intervals on the dust block 6. A locking device 10 is provided at the bottom of the dust block 6.

[0029] The specific working principle is as follows: when using this device to lift materials, the spiral roller 3 is driven to start rotating, and the material is poured into the device body 1 from the feed port 4, and then the material is pushed to a high place due to the action of the spiral blades of the spiral roller 3 and falls from the discharge port 5; in the above process, since the material is mica fragments, under the influence of the friction of the rolling fragments and the collision friction between the blades, the fallen powder and dust will slide all the way to the bottom of the inner wall of the device body 1, and then fall from the dust collection hole 8 to prevent accumulation; when the device needs to be cleaned and flushed, water is directly poured in from a high place, and then the spiral roller 3 is started and the locking device 10 is opened to rotate the dust block 6 to open, allowing the sewage to flow out from the gap adapted to the dust block 6 to complete the cleaning process, and finally the dust block 6 is rotated to close the locking device 10 for reset; in summary, this device can discharge the powder and dust that have fallen and accumulated at the bottom of the device body 1 and facilitate cleaning, prevent blockage, will not affect the blades, and improve service life.

[0030] Example 2:

[0031] The above embodiment is further optimized: a cleaning water pipe 9 connected to the interior of the device body 1 is provided on the side of the upper end of the outer wall of the device body 1 away from the discharge port 5. That is, by turning on the switch of the cleaning water pipe 9, water is filled into the device body 1 to clean the inner wall. The provision of the cleaning water pipe 9 makes it easier to clean the interior of the device body 1. A motor 2 is installed at the bottom of the device body 1, and the output end of the motor 2 is fixedly connected to the spiral roller 3. That is, by starting the motor 2, the spiral roller 3 is driven by the output end of the motor 2 to start rotating. The provision of the motor 2 makes it easier to control the rotation of the spiral roller 3, further facilitating the lifting of materials within the device body 1. A dust guide plate 7 is provided at the outer bottom of the dust block 6. That is, powder dust falling from the dust hole 8 will fall into the dust guide plate 7 and be guided and discharged by the dust guide plate 7. The provision of the dust guide plate 7 makes it easier to collect dust. The locking device 10 includes an installation box 101 provided at the bottom of the dust block 6, and a plug 102 is movably installed in the installation box 101, extending from the installation box 101 and inserted into the outer wall of the bottom of the device body 1. Through the arrangement of the installation box 101 and the plug 102, the device can open or close the dust block 6 by extending and retracting the plug 102 in the installation box 101, so that the dust block 6 can be stably maintained in a fixed state, effectively avoiding leakage of materials in the device body 1. A pull rod 104 extending from the installation box 101 is provided on the side of the plug 102 away from the device body 1, and a spring 103 is provided around the pull rod 104 in the installation box 101. Through the arrangement of the spring 103 and the pull rod 104, the device can pull the plug 102 to extend and retract by the pull rod 104, and quickly reset by the spring 103, further facilitating the operation of the locking device 10.
