Description

Technical Field

[0001] This utility model relates to the field of cleaning machines, specifically to a circulating cleaning machine. Background Technology

[0002] In industrial production, the cleaning of precision parts and electronic components often requires multiple processes such as rough washing, fine washing, and rinsing. Therefore, multi-tank cleaning machines, with their advantage of enabling continuous multi-process cleaning, have become commonly used equipment for cleaning such products. However, in actual use, each cleaning tank in a multi-tank cleaning machine independently holds the cleaning solution. During the cleaning process, impurities detached from the product surface mix into the cleaning solution, causing the cleanliness of the solution to continuously decrease with each batch. Continuing to use this impure cleaning solution will directly affect the cleaning effect of subsequent batches, such as secondary adhesion of impurities and incomplete cleaning. To ensure product cleaning quality, companies typically discharge cleaning solution that has reached a certain level of contamination and replace it with fresh solution. This method not only results in a large amount of ineffective consumption of cleaning solution, significantly increasing production costs, but also exacerbates the environmental protection burden on companies due to the substantial increase in wastewater discharge. Utility Model Content

[0003] Based on this, and in response to the aforementioned technical problems, this utility model provides a circulating cleaning machine.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A circulating cleaning machine includes a frame and multiple cleaning tanks spaced apart along the length of the frame at the lower part of the frame. Each cleaning tank has a tank cover at its top opening. A drive mechanism connected to the tank cover is fixed on the frame to drive the tank cover to open or close the tank opening. Each cleaning tank is equipped with a circulation mechanism for circulating and filtering cleaning liquid. The circulation mechanism includes a pair of outlet pipes symmetrically arranged on both sides of the top of the cleaning tank. Each outlet pipe is open at one end and closed at the other end. Multiple spray nozzles are spaced apart along the length of the outlet pipe, with each spray nozzle facing downwards. A storage tank is installed on the upper part of the frame. The storage tank has an inlet at the top and an outlet at the bottom. A first valve is connected to the outlet of the cleaning tank and is connected to the inlet of the storage tank through a first pipeline. A circulating pump for extracting waste liquid and a filter for filtering waste liquid are also connected to the first pipeline. The opening of the outlet pipe is connected to the outlet of the storage tank through a second pipeline and a second valve.

[0006] Using the above technical solution, since the storage tank is located above the outlet pipe, the cleaning agent can be transported to the outlet pipe via the second pipeline by its own gravity, and then sprayed downwards through multiple nozzles on the outlet pipe to rinse the products in the washing basket. After the cleaning tank is filled with cleaning agent, ultrasonic vibration is activated for cleaning, using ultrasonic energy to remove impurities from the product surface and crevices. After ultrasonic cleaning, the ultrasonic device is turned off, and the waste liquid is returned to the storage tank through a circulation pump and the first pipeline. During this process, impurities are filtered out to improve the cleanliness of the recovered cleaning agent, allowing it to be recycled and reducing cleaning agent consumption. Subsequently, the clean cleaning agent in the storage tank is sprayed out again from the nozzles of the outlet pipe through the second pipeline to rinse the products a second time; after rinsing, ultrasonic vibration cleaning is activated again. In this way, by repeatedly rinsing with cleaning agent and ultrasonic vibration cleaning, the cleaning effect is improved, ensuring that impurities on the product surface and in details are thoroughly removed.

[0007] In a specific embodiment of this utility model: the bottom of the cleaning tank protrudes downward in an arc shape. In this way, the arc-shaped bottom can guide the cleaning liquid to naturally converge along the arc surface to the bottom outlet, avoiding the liquid retention area formed by the corners of the flat bottom structure. After cleaning, the discharge of waste liquid can be smoother and more efficient, while avoiding the deposition of impurities at the bottom of the tank.

[0008] In a specific embodiment of this utility model: the first valve and the second valve are solenoid valves.

[0009] In summary, in this invention, the cleaning solution is first sprayed from the nozzle of the outlet pipe to rinse the product in the cleaning tank, followed by ultrasonic vibration cleaning. After cleaning, the waste liquid is pumped back to the storage tank by a circulation pump and filtered to remove impurities. Then, the clean cleaning agent in the storage tank is sprayed again from the nozzle of the outlet pipe to rinse the product a second time. After rinsing, ultrasonic vibration cleaning is performed again. This repeated rinsing with cleaning agent and ultrasonic vibration cleaning improves the cleaning effect and ensures that impurities on the product surface and in details are thoroughly removed. Furthermore, the curved bottom guides the cleaning solution in the tank to converge at the bottom outlet along the curved surface, allowing the waste liquid to be discharged smoothly and efficiently after cleaning.

[0016] 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.

[0017] Please see Figure 1 and Figure 2 As shown, this utility model is a circulating cleaning machine, including a frame 10 and a plurality of cleaning tanks 20 spaced apart along the length of the frame 10 at the lower part of the frame 10. Each cleaning tank 20 has a tank cover 22 at its top opening 21. A drive mechanism 23 connected to the tank cover 22 and used to drive the tank cover 22 to open or close the tank opening is fixed on the frame 10. In this embodiment, the drive mechanism 23 can be driven by a cylinder. Thus, when cleaning is required, the product is first placed in a washing basket, and then placed in the cleaning tank along with the washing basket; subsequently, the cylinder drives the tank cover to close, forming a sealed cleaning space. This reduces splashing of the cleaning fluid during the cleaning process, lowering the pollution to the surrounding production environment; it also maintains the stability of the ultrasonic cleaning environment inside the tank, preventing external impurities from falling into the tank and ensuring the cleanliness of the cleaning fluid. The above-mentioned method of driving the tank cover to close the cleaning tank by a cylinder is prior art, disclosed in Chinese patent document "CN222470139U", and will not be described in detail here.

[0018] Combination Figures 3-5As shown, in this embodiment, each cleaning tank 20 is equipped with a circulation mechanism 30 for circulating and filtering the cleaning liquid. The circulation mechanism includes a pair of outlet pipes 31 symmetrically arranged on both sides of the top of the cleaning tank 20. Each outlet pipe 31 is open at one end and closed at the other end. Multiple spray nozzles 311 are spaced apart along the length of the outlet pipe 31, with each spray nozzle facing downwards. A storage tank 32 is installed on the upper part of the frame 10. The storage tank 32 has an inlet 33 at the top and an outlet 34 at the bottom. The outlet 24 at the bottom of the cleaning tank 20 is connected to the inlet 33 of the storage tank 32 through a first pipeline. A circulation pump for extracting waste liquid and a filter for filtering waste liquid are also connected to the first pipeline. A first valve is connected to the outlet 24 of the cleaning tank 20. The opening of the outlet pipe 31 is connected to the outlet 34 of the storage tank 32 through a second pipeline 35 and a second valve. Here, the first and second valves can be solenoid valves.

[0019] In this embodiment, the outlet pipe 31 is installed inside the cleaning tank 20 via a first flange 36. Specifically, perforations are provided on both sides of the top of the cleaning tank 20, and a second flange 37 is welded to the perforations inside the cleaning tank 20. The end of the second pipe 35 is connected to the outlet pipe 31 in sequence, corresponding to the perforations and the second flange 37. The first flange 36 is fitted onto the open end of the outlet pipe 31 and is bolted to the second flange 37, thereby fixing the outlet pipe 31 inside the cleaning tank 20.

[0020] When cleaning is required, the product is first placed in the washing basket, then placed in the cleaning tank along with the basket, and the tank cover is closed. Since the storage tank 32 is located above the outlet pipe 31, after opening the second valve, the cleaning agent in the storage tank 32 can be transported to the outlet pipe 31 through the second pipeline by its own gravity, and then sprayed downwards through multiple nozzles 311 on the outlet pipe 31 to rinse the product in the washing basket. After the cleaning tank 20 is filled with cleaning agent, ultrasonic vibration is started to clean the product in the tank, using ultrasonic energy to remove impurities from the surface and crevices of the product. After the ultrasonic cleaning is completed, the ultrasonic device is turned off, the first valve and the circulation pump are turned on, and the waste liquid in the cleaning tank flows back to the storage tank 32 through the circulation pump and the first pipeline. During the process, impurities are filtered out by the filter to improve the cleanliness of the recovered cleaning agent, allowing it to be recycled and reducing cleaning agent consumption. Subsequently, the clean cleaning agent in the storage tank 32 is sprayed out from the spray nozzle 311 of the outlet pipe 31 through the second pipeline to perform a second rinsing of the product; after rinsing, ultrasonic vibration cleaning is started again. In this way, by repeatedly rinsing with cleaning agent and ultrasonic vibration cleaning, the cleaning effect is improved, ensuring that impurities on the surface and in the details of the product are thoroughly removed.

[0021] In this embodiment, the bottom of the cleaning tank 20 protrudes downward in an arc shape. In this way, the arc-shaped bottom can guide the cleaning liquid to naturally converge along the arc surface to the bottom outlet, so that the waste liquid can be discharged smoothly and efficiently after cleaning, while also preventing impurities from accumulating at the bottom of the tank.

[0022] In summary, this invention improves the cleaning effect by repeatedly rinsing with cleaning agent and ultrasonic vibration cleaning, ensuring that impurities on the product surface and in details are thoroughly removed.

[0023] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
