Description

Technical Field

[0001] The invention relates to the technical field of copper strip production, and in particular to a phosphor bronze feeding structure and a melting furnace. Background Art

[0002] The existing melting furnace for copper strip production is relatively common. In the related technology, large particles or powders are directly put into the melting furnace. The larger particles are easier to store and transport, but there is a risk of large particles hitting the inner wall of the furnace body, which can easily cause damage to the inner wall of the furnace body. In addition, large particles lead to high losses, which increases production costs. If powder is used for feeding, the powder is not easy to preserve and is easy to absorb moisture during storage. If it is directly put into the furnace, water vapor will appear inside the furnace body and the upper cover during the melting process, resulting in a decrease in the production quality of the copper strip.

[0003] Therefore, it is necessary to provide a phosphor bronze feeding structure and a melting furnace with large particle grinding treatment. Summary of the invention

[0004] The invention provides a phosphor bronze feeding structure to solve the above technical problems.

[0006] Furthermore, a plurality of decomposition cones are fixed on the inner wall of the outer cover near the bottom.

[0007] Furthermore, an arcuate surface is provided on the outer periphery of the top surface of the filter plate, and the arcuate surface is inclined downward in a direction away from the center of the driven turntable.

[0008] Furthermore, a chamfered surface is provided on the bottom edge of one end of the divided grinding member facing the arc-shaped surface.

[0009] Furthermore, the driven platform is in a frustum-shaped form, and the radius of the driven platform gradually increases from top to bottom.

[0010] Furthermore, the feeding structure also includes two U-shaped frames, the U-shaped frames are fixedly connected via a transverse support, and the top surface of the outer cover is fixed on the bottom surface of the transverse support.

[0011] Furthermore, a driving assembly is provided on the transverse support, and the driving assembly is connected to the driven platform via a rotating shaft.

[0012] Furthermore, an extension seat is fixed to the bottom of the outer cover.

[0013] Furthermore, the decomposition cone is provided with a sharp corner, and the sharp corner is perpendicular to the chamfered surface.

[0014] The present invention further provides a melting furnace, wherein the feeding structure as described above is arranged above the melting furnace, the melting furnace is arranged in a sinking trough, and the top surface of the melting furnace is flush with the ground.

[0015] Compared with the prior art, the beneficial effects of the present invention are: By setting up the grinding parts, the existing large particles can be made into small particles for feeding, which solves the problem that large particles are easy to damage the inner wall of the furnace and the powder is not easy to store and absorb moisture; By setting a truncated cone-shaped driven table, the material can be discharged to the filter plate below the grinding element under the slow flow, which improves the uniformity of material dispersion, allows the material to enter the furnace evenly, and improves the melting efficiency; By setting the filter plate and decomposition cone with downward slope on the outer edge, the materials that cannot be crushed by rotating downward pressure can be crushed again at the bottom edge inside the outer cover, avoiding the retention of larger particles or even clogging the filter plate; By placing the melting furnace underground, the safety of the melting furnace is enhanced, the heat preservation effect is improved, and the difficulty of loading and unloading operations is reduced.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

Figures 1 to 3 As shown, at least one embodiment provides a phosphor bronze feeding structure, including: an outer cover 3, the feeding structure also includes two U-shaped frames 1, the U-shaped frames 1 are fixedly connected by a cross support 2, and a driving assembly is installed on the cross support 2, and the driving assembly includes a servo motor. The top surface of the outer cover 3 is fixed on the bottom surface of the cross support 2, and the driving assembly is connected to the driven platform 9 through a rotating shaft 8, that is, the rotating shaft 8 is connected to the output end of the servo motor, and the servo motor can control the rotating shaft 8 to rotate clockwise or counterclockwise. An extension seat 4 is fixed to the bottom of the outer cover 3, and the extension seat 4 is used to rest on the top surface of the melting furnace 5 when feeding, so as to avoid material splashing and improve the safety of feeding.

[0021] Please continue reading Figure 2 Combined with Figure 3 to Figure 4 , Figure 4 1 is a perspective view of the best embodiment of the feeding structure and melting furnace of the present invention. Figures 2 to 4 As shown, a driven table 9 is arranged at a concentric position in the outer cover 3. The driven table 9 is truncated, and the radius of the driven table 9 gradually increases from top to bottom. The inclined table surface allows the material to slowly fall along its outer wall to the bottom edge of the driven table 9. The material at the bottom edge is continuously squeezed and pushed outward as the grinding pieces 10 rotate, and some particles that cannot pass through the discharge holes continue to be pushed and squeezed toward the outer edge of the circumference. A plurality of grinding pieces 10 are installed on the outer wall of the driven table 9, and a filter plate 7 is installed at the bottom of the outer cover 3. The filter plate 7 includes discharge holes arranged at equal intervals. Materials within a certain particle size evenly enter the melting furnace 5 from the discharge port, which not only avoids collision, but also enhances the melting uniformity and improves the smelting effect; the filter plate 7 and the bottom of the grinding piece 10 form a certain gap. The gap is used to squeeze and crush the material. In order to avoid the accumulation of large particles, a plurality of decomposition cones 31 are fixed near the bottom of the inner wall of the outer cover 3. The decomposition cone 31 is provided with a sharp corner, and the sharp corner is perpendicular to the chamfered surface 11. The outer periphery of the top surface of the filter plate 7 is provided with an arc surface, and the arc surface is inclined downward in a direction away from the center of the driven turntable. The materials concentrated on the edge of the inner wall of the outer cover 3 will continue to be decomposed by the chamfered surface 1 and the decomposition cone 31, further improving the material processing accuracy; the bottom edge of the grinding member 10 facing one end of the arc surface is provided with a chamfered surface 11.

[0022] See also Figure 4 Combined with Figure 5 , Figure 5 FIG. 1 is a schematic diagram of the structure of the best embodiment of the melting furnace and the sinking tank of the present invention. Figures 4 to 5As shown, the present invention also provides a melting furnace, the feeding structure as described above is arranged above the melting furnace 5, the melting furnace 5 is arranged in the sinking trough 6, and the top surface of the melting furnace 5 is flush with the ground.

In addition, the melting furnace 5 is accommodated below the ground, which not only enhances the thermal insulation effect, but also improves safety and reduces the difficulty of operation.
