Description

Technical Field

[0001] The utility model belongs to the technical field of caustic soda flake feeding devices, and more specifically, particularly relates to a caustic soda flake feeding device for aluminum oxide electroplating. Background Art

[0002] Aluminum oxide electroplating is a widely used surface treatment process with many advantages. The steps of aluminum oxide electroplating mainly include: substrate pretreatment, electrolyte preparation, stirring, cleaning, oxidation, cleaning, sealing and other steps. In the preparation of the electrolyte, the electrolyte needs to be configured according to production needs, and the electrolyte temperature, pH value and other parameters need to be adjusted. When adjusting the pH value and other parameters, it is necessary to add caustic soda flakes. Caustic soda flakes added to the electrolyte can not only adjust the pH value of the electrolyte, but also play the role of conductor and clean the electroplating layer. Caustic soda flakes are flaky solids and are generally packaged in 25kg three-layer plastic woven bags. The inner and outer layers are plastic woven bags, and the middle layer is a plastic inner film bag. When storing caustic soda flakes, attention should be paid to moisture-proof to avoid caking of caustic soda flakes. When putting caustic soda flakes into the electrolyte pool, it is usually necessary to use a caustic soda flake feeding device. The existing caustic soda flake feeding device is usually composed of a storage hopper and a screw conveyor. In order to avoid caking of caustic soda flakes and affect the later dissolution rate in the electrolyte, the storage hopper usually has a crushing function. When putting caustic soda flakes, disassemble the plastic woven bag containing caustic soda flakes and pour the caustic soda flakes into the storage hopper. After the storage hopper completes the crushing, it puts the crushed caustic soda flakes into the electrolyte pool through the screw conveyor to complete the operation of putting caustic soda flakes.

[0003] The existing application number is: CN201822153111.2. The utility model discloses a solid caustic soda feeder, including a sleeve and a spiral rod; the two ends of the spiral rod are fixedly connected to the sleeve through bearings; the sleeve is provided with a heavy hammer flap at one end close to the discharge hole; the cover body of the heavy hammer flap contacts the end of the sleeve, and the cover body can completely cover the end of the sleeve; the sleeve is provided with a storage hopper near the end away from the discharge hole; the lower part of the storage hopper has an inverted conical discharge hopper; the top of the storage hopper is provided with a sealing cover; the spiral rod is connected to a driving motor at one end close to the storage hopper. The solid caustic soda feeder of the utility model has a simple structure, is easy to use, and has low manufacturing and operation and maintenance costs; it is not easy to get stuck, and is suitable for feeding caustic soda or other materials with large particles and irregular shapes; the setting of the heavy hammer flap and the sealing cover can effectively block the air and prevent the caustic soda from getting damp.

[0004] Based on the above, flake caustic soda is a highly alkaline substance. Workers need to avoid skin contact and lung inhalation when putting flake caustic soda. When crushing the flake caustic soda in the storage hopper, a large amount of alkali-containing dust is easily generated. These alkali-containing dusts are easily inhaled into the lungs of workers. Therefore, a protective cover needs to be set above the storage hopper. Although there are automatic opening and closing protective covers driven by electric drive or cylinder push rod, it will increase the manufacturing cost and the cost of subsequent repair and maintenance. When using a manually opened and closed protective cover, before the worker pours the bagged flake caustic soda into the storage hopper, the protective cover needs to be opened first, and then the bagged flake caustic soda is poured into the storage hopper. After pouring the flake caustic soda, in order to avoid the volatilization of the alkali-containing dust, the protective cover needs to be closed. When a large amount of flake caustic soda is needed, the protective cover needs to be opened and closed manually, which increases the work steps and affects the efficiency of putting flake caustic soda.
