Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrolytic degreasing technology, and in particular to an electrolytic water tank degreasing device. Background Technology
[0002] After metal workpieces are machined, residual oil on the surface forms an oil film, which affects subsequent electroplating processes. This oil film is typically removed by electrolytic degreasing.
[0003] During electrolytic degreasing, the metal workpiece is immersed in an alkaline electrolyte and a DC power supply is applied. Electrode polarization occurs on the workpiece surface, which acts as the cathode or anode, significantly reducing the interfacial tension between the oil and the solution. This makes it easier for the solution to wet the metal surface, weakens the oil film adhesion, and makes the oil easier to peel off. At this time, the emulsifier in the electrolyte further encapsulates the oil droplets, dispersing them to form a stable emulsion.
[0004] As the metal parts in the electrolytic water tank are electrolyzed and degreased, the oil in the tank floats in the alkaline electrolyte and eventually rises to the surface of the electrolyte. This makes it easy for the metal parts to be contaminated with oil during the removal process, affecting the cleaning quality of the metal parts. Utility Model Content
[0005] The purpose of this invention is to provide an oil removal device for an electrolytic water tank to solve the problem of oil stains floating on the surface of the electrolyte during the electrolytic oil removal process, which causes surface contamination of metal parts.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An oil removal device for an electrolytic water tank, comprising:
[0007] An electrolytic water tank is used to hold alkaline solutions, and a drain outlet is provided on one side of the electrolytic water tank.
[0008] The oil scraping module includes a first oil scraping unit and a second oil scraping unit. The first oil scraping unit includes a first slide rail, a first mounting bracket, a first scraper, and a first drive motor. The first slide rail is fixedly installed on the side wall of the electrolysis tank. The first mounting bracket is slidably connected to the first slide rail. The first scraper is rotatably installed on the first mounting bracket. The first drive motor is fixedly installed on the first mounting bracket. The rotating shaft of the first scraper is connected to the output end of the first drive motor.
[0009] The circulating water tank is located on one side of the electrolysis tank. The circulating water tank is connected to the electrolysis tank through a return pipe. A solenoid valve is installed on the return pipe. A stirring motor is installed below the circulating water tank. The motor shaft of the stirring motor passes through the circulating water tank and is connected to the stirring component.
[0010] As a further description of the above technical solution:
[0011] An ultrasonic cleaner is also installed on one side of the electrolysis tank.
[0012] As a further description of the above technical solution:
[0013] The base plate of the drain outlet is arranged at an angle downwards.
[0014] As a further description of the above technical solution:
[0015] A collection box is installed below the drain outlet, and an opening is provided on the top of the collection box.
[0016] As a further description of the above technical solution:

Detailed Implementation
[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1
[0031] Please see Figure 1-3 This utility model provides a technical solution: an oil removal device for an electrolytic water tank, comprising:
[0032] Electrolytic water tank 1 is used to hold alkaline solution, and a drain outlet 11 is provided on one side of electrolytic water tank 1;
[0033] The oil scraping module 2 includes a first oil scraping unit 21 and a second oil scraping unit 22. The first oil scraping unit 21 includes a first slide rail 211, a first mounting bracket 212, a first scraper 213 and a first drive motor 214. The first slide rail 211 is fixedly installed on the side wall of the electrolytic water tank 1. The first mounting bracket 212 is slidably connected to the first slide rail 211. The first scraper 213 is rotatably installed on the first mounting bracket 212. The first drive motor 214 is fixedly installed on the first mounting bracket 212. The rotating shaft of the first scraper 213 is connected to the output end of the first drive motor 214.
[0034] The circulating water tank 3 is located on one side of the electrolytic water tank 1. The circulating water tank 3 is connected to the electrolytic water tank 1 through the return pipe 31. A solenoid valve is installed on the return pipe 31. A stirring motor 4 is installed below the circulating water tank 3. The motor shaft of the stirring motor 4 passes through the circulating water tank 3 and is connected to the stirring component 41.
[0035] After the metal parts are connected to the electrodes and placed in the electrolytic water tank 1 for a period of time for electrolytic degreasing, the oil layer floating on the solution surface is scraped off by the oil scraping module 2. The first oil scraping unit 21 and the second oil scraping unit 22 achieve two consecutive scrapings, effectively removing the oil layer on the solution surface and avoiding contamination of the metal parts after degreasing.
[0036] For solutions in the electrolytic water tank 1 that require a long time to degrease, the solenoid valve can be opened to allow the solution to be connected to the circulating water tank 3 via the return pipe 31. After the stirring motor 4 drives the stirring element 41 to rotate, the solution will be further separated from the oil under the action of centrifugal force, achieving liquid stratification and facilitating the removal of oil.
[0037] The base plate 111 of the drain outlet 11 is arranged at an angle downwards to facilitate the discharge of oil stains scraped by the oil scraping module 2.
[0038] Working Principle: The first oil scraping unit 21 and the second oil scraping unit 22 have the same structure and working principle. Taking the first oil scraping unit 21 as an example, the first mounting bracket 212 in the first oil scraping unit 21 achieves linear movement through the first slide rail 211, causing the first scraper 213 to move towards the drain outlet 11, scraping the oil stains on the solution surface out of the drain outlet 11. The bottom height of the first scraper 213 can be adjusted by rotating the first drive motor 214 to ensure the oil scraping effect. Similarly, the height of the second scraper in the second oil scraping unit 22 is adjustable, and the bottom height of the second scraper is different from that of the first scraper 213, ensuring that the oil scraping effect of the two scraping operations is not consistent.
[0039] Example 2
[0040] Based on the above embodiments, this embodiment further improves upon the following technical solution: an ultrasonic cleaner 5 is also provided on one side of the electrolytic water tank 1 to facilitate further cleaning of the degreased metal parts and improve the cleaning effect of the metal parts.
[0041] Example 3
[0042] This embodiment further improves upon the above embodiment by providing the following technical solution: a collection box 6 is provided below the drain outlet 11, and the top of the collection box 6 has an opening. The oil scraped by the oil scraping module 2 is discharged through the drain outlet 11 into the collection box 6 for collection.
[0043] The bottom of the collection box 6 is equipped with several casters, which are omnidirectional wheels, making it easy to move the collection box 6.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
