[0025] See Figures 1 to 3 An automatic antimony feeding device for an antimony white furnace includes: a fixed frame 100, a conveying pipe 110 inclinedly arranged on the fixed frame 100, a plurality of spiral blades 111 for lifting materials built into the conveying pipe 110, the spiral blades 111 being connected to a first driving component for driving them to rotate, a feeding frame 120 connected to the lower end of the conveying pipe 110, a pushing component movably arranged on the feeding frame 120, a discharge frame 130 connected to the upper end of the conveying pipe 110, a lifting frame 140 movably arranged in the vertical direction on the discharge frame 130, a second driving component for driving it to move, and a discharge port for connecting to the antimony white furnace opened at the lower end of the lifting frame 140.

[0026] The above-described automatic antimony feeding device for an antimony white furnace operates as follows: The furnace charge is fed into the feeding frame 120. The pushing component then pushes the charge into the conveying pipe 110. Next, the first drive component rotates the spiral blades 111, gradually conveying the charge along the conveying pipe 110 to the discharge frame 130. Finally, under gravity, the charge is fed into the antimony white furnace from the discharge port of the lifting frame 140, completing the charging process. The pushing component and conveying pipe 110 achieve upward conveying of the charge, allowing for charging from a lower position away from the furnace body. The automatic feeding reduces the difficulty of manual charging and improves safety. Furthermore, the second drive component adjusts the position of the discharge port on the lifting frame 140, allowing the device to be used with charging ports at different furnace heights, thus expanding its applicability.

[0027] See Figures 1 to 3 Furthermore, the pushing assembly includes a first cylinder 121, the telescopic end of which is connected to a pushing plate 122. The feeding frame 120 is provided with an upward-facing groove 123, which communicates with the conveying pipe 110. The pushing plate 122 slides against the side wall of the groove 123. Specifically, in the initial position, the pushing plate 122 is located away from the conveying pipe 110, forming a feeding area for temporary storage of furnace charge between the pushing plate 122 and the conveying pipe 110. When the furnace charge is fed into the feeding area, the first cylinder 121 drives the pushing plate 122 to move towards the side closer to the conveying pipe 110, thereby facilitating the gradual pushing of the furnace charge into the interior of the conveying pipe 110, which in turn facilitates the subsequent transport of the furnace charge by the conveying pipe 110. In some embodiments, the pushing assembly can also be replaced by a motor-driven gear rack, which can also drive the pushing plate 122 to achieve horizontal translational movement.

[0028] See Figures 2 to 3 Furthermore, the discharge frame 130 has two side plates 131 arranged opposite each other inside. The side plates 131 have waist-shaped holes 132 arranged in the vertical direction. The side wall of the lifting frame 140 has a through hole. The through hole and the waist-shaped hole 132 are connected by a pin 141. The pin 141 and the inner wall of the waist-shaped hole 132 form a sliding fit, thereby guiding and limiting the movement of the lifting frame 140, which is conducive to regulating the translational movement of the lifting frame 140.

[0029] See Figures 1 to 3Furthermore, the second drive assembly includes a second cylinder 150 disposed on the discharge frame 130. A crossbar 151 is connected to the telescopic end of the second cylinder 150. The crossbar 151 is connected between two opposite side walls of the lifting frame 140, thereby driving the lifting frame 140 to move vertically via the second cylinder 150. This facilitates the discharge port's alignment with the feeding ports of furnace bodies at different heights. In some embodiments, the second drive assembly can also be replaced by a motor driving a gear and rack, which similarly enables the lifting frame 140 to achieve vertical translational movement via the rack.

[0030] See Figures 2 to 3 Furthermore, two mounting rings 133 are arranged opposite each other on the side plate 131, and a rotating shaft 134 is rotatably arranged between the two mounting rings 133. The rotating shaft 134 is connected to a baffle 135, and a torsion spring 136 is sleeved on the rotating shaft 134. One end of the torsion spring 136 abuts against the side plate 131, and the other end of the torsion spring 136 abuts against the lower end face of the baffle 135. Specifically, in use, the furnace charge enters the discharge frame 130 from the upper end of the conveying pipe 110. The furnace charge abuts against the baffle 135 downwards, and then the baffle 135 rotates under force, driving the torsion spring 136 to generate elastic potential energy. Finally, after the furnace charge is fed into the furnace body from the discharge port, the torsion spring 136 drives the baffle 135 to deflect away from the discharge port to the initial position. Through the above structure, the baffle 135 can buffer the falling furnace charge, which helps to reduce the splashing phenomenon caused by the furnace charge falling into the furnace body from a high position.

[0031] See Figures 2 to 3 Furthermore, two baffles 135 are provided, and the two baffles 135 are respectively provided on the corresponding side plates 131, so that the two baffles 135 form a larger projected area that overlaps with the discharge port, thereby better buffering the furnace charge.

[0032] See Figures 1 to 2 Furthermore, the first drive assembly includes a motor 112, the output end of which is connected to a first bevel gear 113. The first bevel gear 113 meshes with a second bevel gear 114, which is connected to a rotating shaft 115. Multiple helical blades 111 are helically wound around the rotating shaft 115. Specifically, the motor 112 drives the first bevel gear 113 to rotate, and the first bevel gear 113 drives the second bevel gear 114 to rotate synchronously, thereby driving the rotating shaft 115 to rotate the multiple helical blades 111, and thus driving the furnace charge to be conveyed from bottom to top.

[0033] See Figures 1 to 2 Furthermore, the feed frame 120 is provided with a mounting plate 124 in the horizontal direction, and a vertical plate 125 is connected between the mounting plate 124 and the motor 112, so as to improve the stability of the motor 112 by using the vertical plate 125.

[0034] See Figures 1 to 2 Furthermore, the fixing frame 100 includes multiple first uprights 101 and second uprights 102. The first uprights 101 are disposed on the lower end face of the feeding frame 120, and the upper ends of the second uprights 102 are connected to the conveying pipe 110. An mounting rod 103 connects the first uprights 101 and the second uprights 102, thereby fixing the feeding frame 120 and the conveying pipe 110 respectively using the first uprights 101 and the second uprights 102. The first uprights 101 and the second uprights 102 have different heights, which facilitates the conveying pipe 110 to be inclined relative to the feeding frame 120.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
