Description

Technical Field

[0001] The utility model relates to the technical field of production equipment for electrolytic copper foil, in particular to a feeding device for a copper dissolving tank. Background Art

[0002] In the production process of electrolytic copper foil, the function of the copper dissolving tank is to evenly distribute the copper raw materials (copper plates or copper wires, copper rice, etc. that have been sheared and then alkali-washed, water-washed, and pickled) in the copper dissolving tank and dissolve the copper raw materials into copper sulfate solution under certain conditions. Copper dissolving is the first process in the production of electrolytic copper foil and is a key and important process. Whether the copper dissolving process runs normally and stably is directly related to whether the production of electrolytic copper foil can run smoothly, normally and stably and whether the quality of electrolytic copper foil can be stable. In addition to temperature, oxygen content, acidity, and copper material size, the most important influencing factor is the copper dissolving efficiency. Copper foil production is a process of copper precipitation. In order to ensure the stability of process parameters and system balance, the amount of copper added to the copper dissolving tank every day in the copper dissolving process must be greater than the amount of copper precipitation produced. The amount of copper added to the copper dissolving process is calculated based on the output of copper foil in the raw foil process. The employees on duty first use a crane to lift the copper raw materials to the inlet of the copper dissolving tank, and then manually pour the copper raw materials into the copper dissolving tank to dissolve. This operation method not only has low work efficiency and high labor intensity for employees, but also there is a risk of safety accidents due to splashing of copper sulfate electrolyte during the pouring process, which may injure people.

[0003] In the prior art, the above-mentioned problems are generally improved by optimizing the feeding device or the copper dissolving device. For example, Chinese patent CN102963689A discloses an automatic feeding machine for a copper foil copper dissolving tank, which includes a frame and a silo, as well as a screw conveying device, a tank opening switch device and a PLC control unit. Chinese patent CN212558509U discloses an automatic feeding device for a copper dissolving tank, which includes a copper dissolving tank, the bottom four corners of the copper dissolving tank are fixedly connected to support columns, the right side wall of the copper dissolving tank is fixedly connected to a lifting plate, the top of the lifting plate is fixedly installed with a first motor, the transmission end of the first motor passes through the top of the lifting plate and is connected to the top of the screw, and the left side of the discharge pipe is fixedly connected to a discharge port. Both of the above inventions realize the transition from manual feeding to automatic feeding. However, the cost of the automated device is high, it is prone to malfunction, and requires frequent maintenance and repair. Therefore, it is necessary to develop a simple, low-cost copper dissolving tank feeding device that can improve work efficiency and reduce the risk of safety accidents. Utility Model Content

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In one embodiment, the feeding device for the copper melting tank is made of stainless steel and includes a feeding box 1, a box door and a lifting ear. The feeding box 1 includes upper and lower top and bottom surfaces, as well as front and rear side surfaces and a left side surface. The box door is a movable box door 2, which is movably connected to the top of the right side of the feeding box 1 by a hinge. The top surface where the feeding box 1 body is connected to the box door is longer than the bottom surface opposite to it, that is, the movable box door 2 is inclined when it is tightly closed with the feeding box 1 (the lower side is shorter than the upper side); a movable box door opening and closing control device 5 is also provided in the feeding device, and the movable box door opening and closing control device 5 includes an inclined baffle, a straight rod and a handle. The straight rod passes through a sleeve welded and fixed on the lower surface of the feeding box 1, and one end is connected to the inclined baffle and the other end is connected to the handle. The inclined baffle is located outside the position where the movable box door 2 is closed. On the side, a hanging ear 7 is fixedly installed on the outside of the box wall opposite to the movable box door 2, and the handle is fixed on the hanging ear 7. A symmetrical C-shaped support plate is also provided under the bottom surface of the feeding box 1, which makes the feeding box more stable when placed on the ground, and also prevents the movable box door opening and closing control device 5 from touching the ground when placed on the ground, playing a protective role; the lifting ear includes a lifting ear 3 and a pouring ear 4, and the four symmetrical lifting ears 3 are welded and fixed to the top of the feeding box 1, and the pouring ear 4 is welded and fixed at an angle on the outer wall of the box surface opposite to the movable box door 2; two raised box bottom supports 6 are also welded on the bottom surface of the feeding box 1, and the structure is a long strip with a triangular cross-section. The box bottom support 6 is parallel to the movable box door 2 and perpendicular to the pouring direction of the copper material, and the two ends are against the two opposite front and rear sides of the feeding box 1.

[0021] In the production process of electrolytic copper foil, the amount of copper to be added in the copper dissolving process is calculated according to the output of copper foil in the raw foil process. The copper dissolving worker first turns the movable box door opening and closing control device 5 by the handle, so that the inclined baffle fixed at its end is blocked outside the movable box door 2, so that the movable box door 2 is closed at the feeding box 1. Then, the clean copper raw materials (mainly copper plates or copper wires, copper rice, etc. that have been sheared and alkali-washed, water-washed, and pickled) are filled into the feeding box 1 by a crane, and the feeding box 1 is lifted by the lifting lug 3. After being transported to the feeding port of the copper dissolving tank, the handle of the movable box door opening and closing control device 5 is turned to make the inclined baffle horizontal or downward, and the movable box door 2 is no longer blocked and limited. The movable box door 2 can move freely. Due to the action of gravity, it mainly maintains the vertical downward direction, so that the feeding box 1 is opened, and the two lifting chain hooks on the lifting lug 3 near the movable box door 2 are opened, and one of the lifting chain hooks is hung on the material pouring lug 4. The copper raw material is poured into the copper dissolving tank using the material pouring lug 4, so that the feeding box 1 is turned over and poured. If lump copper material is added, the copper material falls directly on the bottom support member 6 of the feeding box 1 during the falling process and bounces up, so that the copper material subsequently falls in mid-air, reducing the friction between the copper material and the bottom of the feeding box 1, so that the lump copper material can be quickly added to the copper dissolving tank. After the device is applied to the copper material adding operation of the electrolytic copper foil copper dissolving tank, the practical effect is significant. The device uses stainless steel as its basic material, and has the characteristics of simple design, easy operation, time and labor saving, high efficiency, high safety and reliability. It also has the characteristics of strong wear resistance, corrosion resistance and long service life, creating conditions for ensuring uniform, continuous and stable production of electrolytic copper foil.
