Description

A sponge indium pressing device Technical Field

[0001] This utility model belongs to the field of non-ferrous metal smelting technology, and specifically relates to a sponge indium pressing device. Background Technology

[0002] Wet indium recovery is one of the main processes for tapping the potential and increasing efficiency in tin smelting. Currently, sponge indium ingot pressing generally uses the most primitive manual die-casting with jacks. The pressing process requires manual feeding and operation of the pressing handle, which is labor-intensive and poses high safety risks. In addition, sponge indium contains acidic electrolyte, and there is a risk of skin corrosion from direct contact with the acidic liquid during manual feeding and ingot pressing.

[0003] Therefore, how to provide a safe and reliable sponge indium pressing device is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a sponge indium pressing device that is simple and convenient to operate, has low safety risks, and is easy to use in production.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sponge indium pressing device, comprising:

[0006] A base, on which a stabilizing bracket is fixedly connected, and a material cylinder is vertically fixedly connected to the base on one side corresponding to the stabilizing bracket. An overflow groove is provided around the top edge of the outer side of the material cylinder, and an overflow hole communicating with the overflow groove is provided on the top wall edge of the material cylinder.

[0007] A top plate is slidably connected to the inside of the material cylinder and squeezes the material inside the material cylinder. A top plate drive source for driving the top plate to rise and fall is fixedly installed on the base.

[0008] A pressure plate is located above the material cylinder. A power source for the pressure plate is fixed on the stabilizing bracket to cause the pressure plate to descend and enter the material cylinder. The pressure plate cooperates with the top plate to press the ingot inside the material cylinder.

[0009] A spiral feeding mechanism is inclined and fixed on the electronic scale of the base, and the spiral feeding mechanism conveys the material to the material cylinder;

[0010] The control box is fixed on the base and is electrically connected to the top plate drive source, the pressure plate power source, the screw feeding mechanism, and the electronic scale.

[0011] The beneficial effects of this utility model are: the material feeding mechanism can complete the feeding of the material into the cylinder, and then the pressure plate and top plate are used to complete the ingot forming of the material in the cylinder. During this process, the electrolyte in the sponge indium overflows from the top of the cylinder into the overflow tank, which is beneficial for subsequent recycling. The use of the spiral feeding mechanism in conjunction with the electronic scale can calculate the feeding amount of the cylinder, making the ingot forming as standardized as possible. The entire ingot forming process is easy to operate and has low safety risks.

[0012] Preferably, an external drain pipe is connected to the bottom wall of the overflow tank, and the external drain pipe is connected to an external electrolyte collection tank.

[0013] The resulting technical effect is that the external drain pipe can collect the electrolyte overflowing from the ingot pressing process in the overflow tank, and then drain it into the electrolyte collection tank. After enrichment, it is recycled back into the electrolytic cell for use, thus saving resources.

[0014] Preferably, the top of the material cylinder is provided with an outwardly expanding horn-shaped material guide pipe, which receives and guides the material discharged by the spiral feeding mechanism.

[0015] The resulting technical effect is that the horn-shaped feed tube can avoid interference between the spiral feeding mechanism and the top plate, and there is a certain amount of feeding misalignment space.

[0016] Preferably, the inclined bottom edge of the spiral feeding mechanism is provided with a feed inlet, and a feed hopper is installed at the feed inlet. The inclined top edge of the spiral feeding mechanism is provided with a discharge outlet, and a guide plate facing the horn-shaped guide tube is installed at the discharge outlet.

[0017] The resulting technical effect is that the material is fed through the hopper, and in the subsequent process, the material is guided into the cylinder by the guide plate at the discharge port, eliminating the need to open the discharge port directly above the cylinder, thus avoiding interference between the discharge and the top plate.

[0018] Preferably, the top plate drive source is an electric telescopic rod, which is fixed on the base and located inside the material cylinder. The telescopic end of the electric telescopic rod is fixedly connected to the top plate, and the top plate is dynamically and slidably connected to the inner wall of the material cylinder. The electric telescopic rod is electrically connected to the control box.

[0019] The resulting technical effect is that the electric telescopic rod can be controlled by a control box, thereby controlling the vertical lifting stroke of the roof.

[0020] Preferably, the power source for the pressure plate is an electric telescopic cylinder, which is fixedly connected to the stabilizing bracket. The pressure plate is fixed to the telescopic end of the electric telescopic cylinder, and there is a liquid-passing gap between the outer peripheral sidewall of the pressure plate and the inner sidewall of the material cylinder.

[0021] The resulting technical effect is that the overflow can overflow from all sides of the pressure plate and then enter the overflow trough through the overflow hole. The liquid passage gap is small, which can ensure the pressing effect of the ingot while also allowing the overflow to pass through. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Referring to Figures 1 to 3 of this utility model, a sponge indium pressing device according to an embodiment of this utility model includes:

[0028] Base 1 is the load-bearing foundation for the installation and bearing of related components. A stabilizing bracket 2 is fixedly connected to the base 1. It is an inverted L-shaped bracket. A material cylinder 3 is vertically fixedly connected to the base 1 and to one side of the stabilizing bracket 2. An overflow groove 4 is provided around the top edge of the outer side of the material cylinder 3. An overflow hole 5 communicating with the overflow groove 4 is provided on the top edge of the material cylinder 3.

[0029] Top plate 6 is slidably connected to the inside of the material cylinder 3 and squeezes the material inside the material cylinder 3. A top plate drive source 7 that drives the top plate 6 to rise and fall is fixedly installed on the base 1.

[0030] The pressure plate 8 is located above the material cylinder 3. The stabilizing bracket 2 is fixed with a pressure plate power source 9 that causes the pressure plate 8 to descend into the material cylinder 3. The pressure plate 8 cooperates with the top plate 6 to press the ingot inside the material cylinder 3.

[0031] The screw feeding mechanism 10 is tilted and fixed on the electronic scale 11 of the base 1. The screw feeding mechanism 10 transfers materials to the material cylinder 3. When the electronic scale 11 refers to the auxiliary control of the material cylinder feeding, it relies on the experience value of the screw feeding mechanism and the data difference of the electronic scale 11 to combine and feedback the feeding amount of the material cylinder. When the screw feeding mechanism feeds materials into the material cylinder and approaches the target range, the running speed of the screw feeding mechanism is reduced, and the final stop of the screw feeding mechanism is controlled by the data feedback of the electronic scale.

[0032] The control box 15 is fixed on the base 1 and is electrically connected to the top plate drive source 7, the pressure plate power source 9, the screw feeding mechanism 10 and the electronic scale 11.

[0033] It should be noted that when pressing the ingot, the pressure plate 8 needs to be lowered into the material cylinder 3 and located at the lower edge of the overflow hole. In this way, when the top plate 6 and the pressure plate 8 work together to press the ingot, the overflowing electrolyte can enter the overflow tank 4 through the overflow hole 5, and the overflow liquid flows through the overnight gap between the pressure plate and the material cylinder.

[0034] In other embodiments, an external drain pipe 12 is connected to the bottom wall of the overflow tank 4. The external drain pipe 12 is connected to an external electrolyte collection tank 13, which can collect the electrolyte again for later reuse.

[0035] In some other specific embodiments, the top of the material cylinder 3 is provided with an outwardly expanding horn-shaped guide pipe 14. The horn-shaped guide pipe 14 receives the material discharged by the guide spiral feeding mechanism 10. The purpose of setting the horn-shaped guide pipe 14 is to achieve spatial avoidance between the material cylinder feed and the pressure plate, so that no interference problem will occur.

[0036] In some other embodiments, the inclined bottom edge of the spiral feeding mechanism 10 is provided with a feed inlet, and a feed hopper 101 is installed at the feed inlet. The inclined top edge of the spiral feeding mechanism 10 is provided with a discharge outlet, and a guide plate 102 facing the horn guide tube 14 is installed at the discharge outlet. The guide plate 102 is spatially misaligned with the pressure plate. The guide plate can guide the material to the horn guide tube and then into the material cylinder.

[0037] In some other embodiments, the top plate drive source 7 is an electric telescopic rod, which is fixed on the base 1 and located inside the material cylinder 3. The telescopic end of the electric telescopic rod is fixedly connected to the top plate 6. The top plate 6 is dynamically and slidably connected to the inner wall of the material cylinder 3 to prevent downward leakage. The electric telescopic rod is electrically connected to the control box 15.

[0038] In some other specific embodiments, the power source 9 of the pressure plate is an electric telescopic cylinder, which is fixedly connected to the stabilizing bracket 2. The stabilizing bracket 2 provides a stable installation base for the electric telescopic cylinder, which can also ensure the stable lifting and lowering process of the pressure plate. The pressure plate 8 is fixed to the telescopic end of the electric telescopic cylinder, and there is a liquid-filled gap between the outer peripheral sidewall of the pressure plate 8 and the inner sidewall of the material cylinder 3.

[0039] The density of the ingot pressed by this device is 7.25 g / cm³. 3 The density of the die-cast sponge indium ingot can reach 7.25 g / cm³. 3 After being packaged and boxed, they can be sold directly.

[0040] The ejection pressure of the top plate of this device is 15MPa to 20MPa.

[0041] The device involves two processes after feeding: First, the pressure plate 8 is controlled by an electric telescopic cylinder to move downwards to the top edge of the material cylinder (lower edge of the overflow hole 5), and the top plate 6 is controlled by the telescopic end of an electric telescopic rod to rise and stop at the middle of the material cylinder 3. Second, the pressure plate 8 is controlled by the electric telescopic cylinder to move above the material cylinder 3, at which point it is at the upper limit of the pressure plate. At this time, the control box 15 controls the electric telescopic rod to make the top plate 6 rise to the top of the material cylinder, and the ingot is pushed out of the material cylinder and manually removed. The above operations are controlled by the relevant buttons in the control box. This device can realize semi-automatic die casting of sponge indium.

[0042] This device is easy to operate, low in cost, safe to operate, and can recycle the electrolyte in sponge indium.
