[0029] The specific embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0030] Example

[0031] See also Figures 1 to 5The utility model discloses a casing spiral feeding device, a preferred embodiment of which is composed of a bracket unit 100, a silo unit 200, an inner screw unit 300 and an outer spiral tube unit 400.

[0032] The support unit 100 is the frame of the entire device. The silo unit 200, the inner screw unit 300 and the outer spiral tube unit 400 are all fixed by the support unit 100 to form a whole.

[0033] The support unit is composed of a silo fixing plate 110, an outer tube fixing module 120, a motor fixing module 130 and a base 140. The outer tube fixing module 120 is used to fix and support the outer tube module 400, and it includes a first support plate 121, a second support plate 122 and a support frame 123. The motor fixing module 130 is used to fix the inner screw drive motor 330, the outer tube drive motor 430 and the drive gear 420, and includes an outer tube motor fixing plate 131, a transmission module fixing plate 132 and an inner screw motor fixing plate 133.

[0034] The base 140 provides support for the entire device and is located at the bottom of the entire device.

[0035] The silo fixing plate 110 is vertically fixed on the base 140. Its bottom is fixed to the upper surface of the base 140 by bolts, and its side wall is fixed to the side wall of the lower part of the silo unit 200, so that the silo unit 200 is connected to the base 140 and kept open upward.

[0036] In the external rotating tube fixing module 120, the first support plate 121 is attached to and connected to the silo fixing plate 110. The top of the first support plate 121 forms a U-shaped structure, and the bottom width of the U-shaped structure matches the width of the support frame 123. The support frame 123 is a square bearing bracket. The bottom of the support frame 123 is fixed to the base 140 by bolts, and its top extends into the U-shaped structure of the first support plate, thereby being restricted by the first support plate to prevent its top from shaking. The second support plate 122 is also fixed to the base 140, but is separated from the first support plate 121 and the support frame 123 by a distance, so as to more reliably support and fix the external rotating tube 410 at different positions.

[0037] Through holes matching the outer diameter of the outer rotating tube 410 are provided on the first supporting plate 121, the second supporting plate 122 and the supporting frame 123. The outer rotating tube 410 passes through the through holes on the first supporting plate 121, the second supporting plate 122 and the supporting frame 123, so that it can only rotate but cannot move in other directions.

[0038] The motor fixing module 130 is used to fix the inner screw drive motor 330 , the outer rotary tube drive motor 430 and the drive gear 420 , and includes an outer rotary tube motor fixing plate 131 , a transmission module fixing plate 132 and an inner screw motor fixing plate 133 .

[0039] In the motor fixing module 130, the outer rotating tube motor fixing plate 131 is installed on the base 140. The transmission module fixing plate 132 is installed on the upper part of the outer rotating tube motor fixing plate 131. The driving gear 420 is installed on the transmission module fixing plate 132. The outer rotating tube driving motor 430 is also fixed on the upper part of the outer rotating tube motor fixing plate 131, on the opposite side of the transmission module fixing plate 132. The rotating shaft of the outer rotating tube driving motor 430 passes through the outer rotating tube motor fixing plate 131 and is connected to the driving gear 420. At the lower part of the outer rotating tube motor fixing plate 132, a through hole matching the outer diameter of the outer rotating tube 410 is provided. The inner screw motor fixing plate 133 in the motor fixing module 130 is installed on the base 140, located on the other side of the silo unit 200, and is used to fix the inner screw driving motor 330.

[0040] The outer rotating tube 410, the driving gear 420 as a transmission module, and the outer rotating tube motor 430 together constitute the outer rotating tube unit 400. The outer rotating tube 410 passes through the through holes on the first support plate 121, the second support plate 122, the support frame 123, and the outer rotating tube motor fixing plate 132, and is fixed by them. An outer wall gear is arranged on the outer rotating tube 430. The driving gear 420 is meshed with the outer wall gear. When the driving gear 420 is driven to rotate by the outer rotating tube motor 430, the driving gear 420 further drives the outer rotating tube 430 to rotate.

[0041] The internal screw unit 300 includes an internal screw 310, a coupling 320 and an internal screw motor 330; the internal screw motor 330 is fixed to the internal screw motor fixing plate 133. The output shaft of the internal screw motor 330 is connected to the coupling 320, and the coupling 320 is further connected to the internal screw 310. When the internal screw motor 330 rotates, the coupling 320 drives the internal screw 310 to rotate.

[0042] The cross-section of the silo unit 200 is a trapezoid that is larger at the top and smaller at the bottom, ensuring that the raw materials can enter the bottom of the silo unit in sequence. The length of the inner screw 310 is greater than the length of the outer spiral tube 410. The outer spiral tube 410 is installed in close contact with the side wall of the silo unit 200, so that the raw materials enter the outer spiral tube 410 after leaving the silo unit 200. The inner screw 310 is sleeved in the outer spiral tube unit and is on the same axis as the outer spiral tube 410. The inner screw 310 passes through the side wall of the silo unit 200, with a portion in the outer spiral tube 410 and the other portion extending into the interior of the silo unit 200 and located at the bottom of the silo unit 200. The width of the bottom of the silo unit 200 matches the outer diameter of the inner screw 310 in the inner screw unit 300, so that when the inner screw 310 rotates, the raw materials at the bottom of the silo unit 200 can be pushed into the outer spiral tube 410, and finally discharged from the other end of the outer spiral tube 410 to feed the lower-level equipment.

[0043] In actual operation, because the inner screw 310 and the outer tube 410 are independently driven by different motors, different rotation speeds can be set for the inner screw drive motor 330 and the outer tube drive motor 430 according to different types of raw materials, thereby realizing differential speed operation of the outer tube 410 and the inner screw 310. Under normal working conditions, the outer tube 410 rotates faster than the inner screw 310, thereby accelerating the forward conveying of the material from the inner screw 310, so that the material is not easily accumulated in the conveying pipeline.

[0044] The present invention also discloses a feeding system using the above-mentioned sleeve spiral feeding device, and in its embodiment, it includes multiple groups of sleeve spiral feeding devices, for example, 6 to 24 groups. The feeding system can have different shapes according to the actual situation of the site. When the main body of the feeding system is cylindrical, these sleeve spiral feeding devices are arranged along the circumference with the center of the main cylinder as the center of symmetry. When the main body of the feeding system is rectangular, these sleeve spiral feeding devices are arranged side by side in a straight line. The sleeve spiral feeding device is used to transfer materials from the upper-level equipment to the lower-level equipment in the feeding system.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, any equivalent changes and modifications made according to the content of the patent application scope of the present invention should be within the technical scope of the present invention.
