Description

Technical Field

[0001] This utility model relates to a cleaning device, specifically a mechanical seal cleaning mechanism for a surface treatment machine. Background Technology

[0002] Electrolytic copper foil, as a core material for lithium-ion batteries and printed circuit boards, directly determines the performance of the final product through its surface quality. Copper foil surface treatment machines (also known as surface treatment equipment) are key equipment in copper foil production. Through a series of electrochemical and chemical treatments within the tank, raw foil undergoes roughening, curing, and anti-oxidation processes to impart specific surface structures and properties to the copper foil.

[0003] During the operation of the surface treatment machine, mechanical seals are generally used at both ends of its drive rollers (such as guide rollers, tension rollers, and submersible rollers) to prevent leakage of the treatment liquid (usually a corrosive acidic or alkaline solution containing solid particles) in the tank and to protect the bearings of the roller system from corrosion and damage.

[0004] However, existing technologies suffer from clogging and scaling problems. The surface treatment bath solution contains a large amount of copper powder, additive decomposition products, and other mechanical impurities. During operation, these impurities easily accumulate in the gaps between the dynamic and static ring friction pairs of the mechanical seal, forming hard scale. Furthermore, after the machine stops working, the copper sulfate solution deposited in the mechanical seal oxidizes, forming solids that adhere to the mechanical seal, affecting drainage and causing corrosion, thus shortening the machine's service life. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a mechanical seal cleaning mechanism for a surface treatment machine. This mechanism can perform drip cleaning of the mechanical seal, dilute the copper sulfate solution, effectively prevent crystallization, and significantly extend the service life of the mechanical seal.

[0006] To achieve the above objectives, the present invention provides a mechanical seal cleaning mechanism for a surface treatment machine, comprising an inlet pipe, wherein the inlet pipe is connected to two branch inlet pipes via a three-way connector, and multiple three-way connectors are provided on the branch inlet pipes. The vertical outlet of each three-way connector is connected to a manual sub-valve, and the manual sub-valve is equipped with a bamboo-joint tube perpendicular to the branch inlet pipes; an inlet switch is provided on the inlet pipe.

[0007] Furthermore, the liquid inlet switch of this utility model is a solenoid valve.

[0008] Furthermore, this invention includes a manual master valve installed on the inlet pipe after the inlet switch.

[0009] Furthermore, the diameter of the inlet pipe of this invention is larger than the diameter of the branch inlet pipe.

[0010] Furthermore, both the inlet pipe and the branch inlet pipe of this utility model are made of corrosion-resistant pipe material.

[0011] Furthermore, the branch inlet pipe of this utility model is fixed by a pipe clamp.

[0012] By means of the above solution, this utility model has at least the following advantages: by supplying liquid through the inlet pipe, the bamboo joint pipes installed on the branch inlet pipes perform drip cleaning of the mechanical seal, diluting the copper sulfate solution, effectively preventing crystallization, and allowing the liquid to flow into the collection tank below along the mechanical seal water pipe, while cleaning the residual copper sulfate solution. This utility model can greatly improve the service life of the mechanical seal and also reduce safety hazards. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 and Figure 2 As shown, a mechanical seal cleaning mechanism for a surface treatment machine includes an inlet pipe 1. The inlet pipe 1 is connected to two branch inlet pipes 5 via a three-way connector 4. Multiple three-way connectors 4 are provided on the branch inlet pipes 5, and the three-way connectors 4 divide into two paths to connect to the branch inlet pipes 5. Multiple three-way connectors are provided on the branch inlet pipes 5 to extend the passage of the branch inlet pipes. The other end of the three-way connector 4 is connected to a manual sub-valve 7. The outlet of the manual sub-valve 7 is connected to a bamboo joint tube 8. The vertical outlet of the three-way connector is connected to the manual sub-valve 7. The manual sub-valve 7 is equipped with a bamboo joint tube 8, which is perpendicular to the branch inlet pipe 5. An inlet switch 2 is provided on the inlet pipe 1, and the inlet switch 2 is a solenoid valve.

[0016] A manual master valve 3 is installed on the inlet pipe 1 after the inlet switch 2.

[0017] The diameter of the inlet pipe 1 of this invention is larger than the diameter of the branch inlet pipe 5.

[0018] Both the inlet pipe 1 and the branch inlet pipe 5 of this utility model are made of corrosion-resistant pipe material.

[0019] The branch inlet pipe 5 of this utility model is fixed by the pipe clamp 6, which can prevent bending deformation and fix the position.

[0020] When this utility model is used, its specific operation is as follows: Connect one end of the inlet pipe 1 to a clean water source. Control the water flow and inlet time through the inlet switch 2. The manual main valve 3 controls the water flow when the solenoid valve fails to work properly. Divert the water flow to the branch inlet pipes 5 on both sides of the surface treatment machine through the first three-way branch pipe connector 4. Connect the branch inlet pipes 5 and the bamboo joint pipes 8 through the three-way branch pipe connector 4. Then control the flow rate of each part through the manual sub-valve 7 to ensure the water flow size. By bending the bamboo joint pipes 8, the water flow is accurately dripped onto the mechanical seal that needs to be cleaned. This utility model can increase or decrease the number of bamboo joint pipes at the outlet according to the amount of water in the tank to be cleaned.

[0021] One end of the inlet pipe 1 is connected to a clean water source. The inlet time is controlled by the inlet switch, and the liquid is dripped once every ten minutes to ensure that the liquid regularly cleans the mechanical seal. Intermittent dripping can reduce the aging of the water pipe due to long-term operation and extend the service life of the water pipe. At the same time, each mechanical seal is equipped with a sub-valve to control the drip size. The tank farthest from the inlet has reduced hydraulic pressure due to distance and the flow is diverted. The water flow is the smallest at the farthest point. Therefore, each bamboo pipe 8 is equipped with a manual sub-valve 7. The main pipe has high hydraulic pressure. The liquid flow before each mechanical seal is controlled by the manual sub-valve 7 to ensure that the water does not overflow the mechanical seal during cleaning.

[0022] This invention solves the problems caused by mechanical seal failure in existing operations, which necessitates machine shutdown for replacement or disassembly for cleaning. These problems include unplanned production line downtime, resulting in significant production losses. Furthermore, mechanical seals are high-value, easily damaged parts, and frequent replacements significantly increase production costs. This invention uses drip cleaning of the mechanical seal to dilute the copper sulfate solution, effectively preventing crystallization. The liquid flows along the mechanical seal's water pipe into a collection tank below, simultaneously cleaning away residual copper sulfate solution. This greatly extends the service life of the mechanical seal and reduces safety hazards.
