Description

Technical Field

[0001] The utility model relates to the technical field of hydrometallurgy, and particularly relates to a forced quantitative feeding device for sponge metal. Background Art

[0002] In the field of hydrometallurgy, during the pressing and forming process of sponge metals such as cadmium, indium, and zinc, the traditional feeding method mainly relies on manual operation. Workers need to manually put the fluffy and flocculent sponge metal into the briquetting machine. Such materials often contain corrosive residues such as dilute sulfuric acid and organic solvents, resulting in a harsh working environment, where workers are prone to chemical burns and have extremely high labor intensity. In addition, manual feeding has low efficiency and difficult quantitative control, making it difficult to meet the requirements of large-scale production.

[0003] To improve the drawbacks of manual feeding, automated feeding devices have been proposed in the prior art. For example, the Chinese utility model patent CN215040642U discloses a fully automatic feeding machine for a sponge metal briquetting machine, which realizes the automatic conveying of materials through designs such as a conical hopper, a feeding mechanism (including a positioning rod, a support rod, and a feeding oil cylinder / cylinder), and a vibration motor. However, it still has the following defects: the bottom of the hopper is a small-diameter round hole with a narrow opening, and the sponge metal is prone to secondary caking at the discharge port, and it is necessary to frequently rely on the feeding mechanism to dredge, resulting in poor feeding continuity and insufficient discharge efficiency; the device relies on the reciprocating motion of the feeding mechanism to force the material to fall, but lacks a constant-volume control structure, resulting in large fluctuations in the feeding amount, making it difficult to meet the precise requirements of the briquetting process for the material amount. Especially when the fluidity of the material varies due to humidity changes, the feeding uniformity deteriorates further, affecting the consistency of the finished product quality. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a forced quantitative feeding device for sponge metal, which realizes high-precision constant-volume feeding and breaks through the harsh requirements of the prior art for the material state.

[0005] The technical solution adopted by the utility model is as follows: A forced quantitative feeding device for sponge metal, comprising a frame and a hopper, characterized in that it further comprises a feeding mechanism and a pushing mechanism;

[0006] The hopper is installed on the frame, and a long-strip discharge port is provided at the bottom of the hopper;

[0007] The pushing mechanism comprises a pushing pipe and a pushing oil cylinder. The axial direction of the pushing pipe is consistent with the length direction of the discharge port. An opening for docking with the discharge port is provided at the top of the pushing pipe. One end of the pushing pipe is docked with the feeding end of the briquetting machine, and a pushing piston connected to the piston rod of the pushing oil cylinder is provided at the other end of the pushing pipe. The material entering the pushing pipe is pushed into the briquetting machine through the pushing oil cylinder;

[0008] The feeding mechanism includes a support frame, a feeding oil cylinder, and a feeding component. The two ends of the support frame are fixedly installed on the frame and are located above the hopper. The feeding oil cylinder is vertically installed on the support frame, and the lower end of its piston rod is connected to the feeding component. The feeding component extends into the hopper, and the feeding component is driven by the feeding oil cylinder to move up and down, pushing the material from the discharge port into the pushing pipe.

[0009] Further, the feeding station of the hopper is located on one side of the hopper. The feeding component includes a connecting frame, linear guide rods, and feeding support rods. The middle of the connecting frame is fixedly connected to the piston rod end of the feeding oil cylinder. There are three linear guide rods, and their lower ends are fixedly installed on the connecting frame. Two of them are symmetrically arranged on both sides of the piston rod of the feeding oil cylinder, and the third one is arranged on the opposite side of the feeding station of the hopper. The upper ends of the linear guide rods are slidably matched with linear bearings or guide sleeves fixedly installed on the support frame. At least two feeding support rods are fixedly connected to the connecting frame and are distributed at intervals along the length direction of the long strip-shaped discharge port. The feeding support rods extend downward to the discharge port of the hopper.

[0010] Further, at least one transverse strengthening rod is fixedly connected between adjacent feeding support rods.

[0011] Further, a vertical strengthening rod is fixedly connected between the transverse strengthening rod and the connecting frame. The vertical strengthening rod is vertically arranged on the opposite side of the feeding station of the hopper. Its lower end is fixedly connected to the transverse strengthening rod, and its upper end is fixedly connected to the connecting frame.

[0012] Further, a guiding inclined plate is provided at the edge of the top opening of the hopper for guiding the material to slide down along the guiding inclined plate into the hopper.

[0013] Further, a vibration motor is fixedly installed on the outer side wall of the hopper. The hopper is connected to the frame through a plurality of elastic members. A detachable sealing plate is provided at the discharge port of the hopper, and the sealing plate is inserted into the opening of the pushing pipe.

[0014] The beneficial effects of the present utility model are as follows: The present utility model improves the disordered feeding structure that traditionally relies on the natural fluidity of materials into a hydraulic-driven forced fixed-volume feeding system. It forcibly pushes the materials in the hopper to the feeding opening of the pushing pipe through the feeding mechanism to complete preliminary quantitative filling. Then, through the pushing mechanism, by driving the linear movement of the pushing piston, the fixed-volume materials in the pushing pipe are secondarily compacted and pushed. The dual effects eliminate the material gaps and compact the loose flocculent materials, ensuring that the materials enter the briquetting machine in a uniform and dense state, breaking through the harsh requirements for the material state in the prior art, and greatly optimizing the uniformity of feeding. Through the cooperation of the long strip-shaped discharge port and multiple feeding support rods distributed at intervals, the sponge metal is divided into multiple strip-shaped material flows, dispersing the pushing pressure and improving the working efficiency.

Detailed Embodiment

[0020] For the convenience of understanding the present utility model, the following will describe the present utility model more comprehensively and meticulously in conjunction with the drawings in the specification and preferred embodiments, but the protection scope of the present utility model is not limited to the following specific embodiments.

[0021] As Figures 1 - 4 shown, a sponge-like metal forced quantitative feeding device provided in this embodiment includes a frame 100, a hopper 200, a feeding mechanism 300, and a material pushing mechanism 400.

[0022] The hopper 200 is flexibly connected to the frame 100 through a plurality of elastic members (such as compression springs or rubber damping blocks), and the elastic members are evenly distributed in the circumferential direction of the hopper 200 for buffering vibration energy and reducing the transmission of the whole machine vibration. A vibration motor 202 is fixedly installed on the outer side wall of the hopper 200 to promote the flow of materials through vibration. The bottom of the hopper 200 is provided with a long strip-shaped discharge port.

[0023] The material pushing mechanism 400 includes a material pushing pipe 401 and a material pushing oil cylinder 403. The axial direction of the material pushing pipe 401 is consistent with the length direction of the discharge port, and an opening for docking with the discharge port is provided at the top thereof. A detachable sealing plate 203 is provided at the discharge port of the hopper 200, and the sealing plate 203 is inserted into the opening of the material pushing pipe 401. Through the design of the sealing plate, while improving the sealing reliability, a dynamic seal is formed with the material pushing pipe 401 to adapt to the relative movement under the vibration condition. The detachable structure is convenient for maintenance or replacement.

[0024] The feeding mechanism 300 includes a support frame 301, a feeding oil cylinder 302, and a feeding component. Both ends of the support frame 301 are fixedly installed on the frame 100 and are located above the hopper 200. The feeding oil cylinder 302 is vertically installed on the support frame 301, and the lower end of its piston rod is connected to the feeding component. The feeding component extends into the hopper 200. By driving the feeding component to move up and down through the feeding oil cylinder 302, the material is pushed from the discharge port into the pushing pipe 401.

[0025] One end of the pushing pipe 401 is docked with the feeding end of the briquetting machine. The other end of the pushing pipe 401 is provided with a pushing piston 402 connected to the piston rod of the pushing oil cylinder 403. The material entering the pushing pipe 401 is pushed into the briquetting machine through the pushing oil cylinder 403.

[0026] As another embodiment, the feeding station of the hopper 200 is located on one side of the hopper 200. A guiding inclined plate 201 is provided at the edge of the top opening of the hopper 200 for guiding the material to slide down along the guiding inclined plate 201 into the hopper 200. This design enables the hopper to be docked with the belt elevator, thereby realizing the automatic connection of the material transmission path in the entire production line and effectively reducing the manual intervention link.

[0027] As another embodiment, the feeding component includes a connecting frame 303, linear guide rods 304, and feeding support rods 305. The middle of the connecting frame 303 is fixedly connected to the piston rod end of the feeding oil cylinder 302. There are three linear guide rods 304, and their lower ends are fixedly installed on the connecting frame 303. Two of them are symmetrically arranged on both sides of the piston rod of the feeding oil cylinder 302, and the third one is arranged on the opposite side of the feeding station of the hopper 200. The upper ends of the linear guide rods 304 are slidably matched with linear bearings or guide sleeves fixedly installed on the support frame 301. The three linear guide rods ensure the smooth reciprocating movement of the feeding component in the vertical direction. The third linear guide rod is arranged on the opposite side of the feeding station of the hopper 200, which not only avoids affecting the feeding but also resists the lateral impact force of the material during feeding on the feeding oil cylinder 302, extending the service life of the feeding oil cylinder 302.

[0028] Three feeding support rods 305 are fixedly connected to the connecting frame 303 and are distributed at intervals along the length direction of the long strip-shaped discharge port. The feeding support rods 305 extend downward to the discharge port of the hopper 200. By arranging multiple feeding support rods 305, the material in the hopper is divided into multiple strip-shaped flows, dispersing the pushing pressure and improving the feeding uniformity.

[0029] To improve the strength of the feeding support rod 305, at least one transverse strengthening rod 306 is fixedly connected between adjacent feeding support rods 305. A vertical strengthening rod 307 is fixedly connected between the transverse strengthening rod 306 and the connecting frame 303. The vertical strengthening rod 307 is vertically arranged on the opposite side of the feeding station of the hopper 200. Its lower end is fixedly connected to the transverse strengthening rod 306, and its upper end is fixedly connected to the connecting frame 303.

Therefore, it is to be understood that the invention is not limited to the specific embodiments disclosed and that modifications and other embodiments are contemplated as being included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
