Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment device for electrolytic copper foil production. Background Art

[0002] The production of electrolytic copper foil is mainly divided into the following three steps:

[0003] 1. Copper Dissolution: First, high-purity electrolytic copper reacts with sulfuric acid at a specific temperature to produce a copper sulfate solution. This step involves a solid-liquid-gas multiphase reaction, requiring control of the copper surface area and air volume. The electrolyte purity is ensured through filtration and fine filtration.

[0004] 2. Raw foil manufacturing: In the electrolytic cell, the electrode system consisting of a titanium-based iridium-tantalum coated anode and a pure titanium cathode roller is used to make Cu 2+ The copper foil is deposited on the cathode roller surface to form an equiaxed copper foil. The thickness control depends on the precise matching of cathode current density and roller speed.

[0005] 3. Surface Treatment: A three-stage electrochemical treatment consisting of a roughening layer, a barrier layer, and an anti-oxidation layer strengthens the bond between the copper foil and the substrate, prevents particle migration, and achieves long-term storage stability.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The technical terms in the embodiments are explained below:

[0028] In wastewater treatment plants used in electrolytic copper foil production, degradation fluid is a key chemical reagent used to decompose organic matter, heavy metal ions, or other pollutants in wastewater. Its composition and function are generally related to the specific needs of wastewater treatment and may include the following components and functions:

[0029] Oxidants: such as hydrogen peroxide (H2O2), potassium permanganate (KMnO4), etc., are used to oxidize and decompose organic matter and reduce chemical oxygen demand (COD).

[0030] Reducing agents: such as sodium sulfite (Na2SO3), used to reduce heavy metal ions (such as chromium and copper) to precipitate or convert them into non-toxic forms.

[0031] Flocculants: such as polyaluminium chloride (PAC) and polyacrylamide (PAM), are used to coagulate suspended matter to facilitate sedimentation or filtration.

[0032] pH regulator: such as sodium hydroxide (NaOH) or sulfuric acid (H2SO4), used to adjust the pH value of sewage and optimize degradation reaction conditions.

[0033] Chelating agents: such as ethylenediaminetetraacetic acid (EDTA), are used to complex heavy metal ions to prevent re-contamination.

[0034] In a wastewater treatment plant, the degradation liquid mixes with the wastewater and, under the action of a stirring component, fully reacts to break down pollutants. The amount and proportion of the degradation liquid used are precisely controlled by a liquid control component to ensure treatment effectiveness and economic efficiency. The selection and formulation of the degradation liquid must be optimized based on wastewater quality and treatment objectives to achieve optimal treatment results.

[0035] In wastewater treatment equipment used in electrolytic copper foil production, the elastic telescopic rod is a key component that combines the design of an elastic element with a telescopic structure to achieve specific mechanical functions. The following is a detailed explanation of the elastic telescopic rod:

[0036] Definition and structure:

[0037] An elastic telescopic rod typically consists of an elastic element (such as a spring) and a telescopic rod body. The elastic element provides the spring force, allowing the rod body to expand and contract when subjected to an external force and return to its original shape when the force is removed. This design allows the elastic telescopic rod to possess both rigid support and a certain degree of flexibility and adaptability.

[0038] Function and principle:

[0039] In sewage treatment plants, the primary function of an elastic telescopic rod is to control the opening and closing of sealing valves and to buffer mechanical shocks. Its operating principle is based on the elastic force of an elastic element and the mechanical transmission of the telescopic rod. When an external force acts on the telescopic rod, the elastic element deforms, storing elastic potential energy. When the external force disappears, the elastic element releases this elastic potential energy, pushing the telescopic rod back to its original shape.

[0040] Specifically in sewage treatment plants, the elastic telescopic rod cooperates with components such as the reciprocating screw and the slider to achieve intermittent opening of the sealing valve. When the reciprocating screw rotates, the slider reciprocates under the limiting action of the slider. When the slider moves to a specific position, the elastic telescopic rod contacts the gate plate and pushes against the gate plate compression spring, connecting the through-hole on the gate plate with the pipe hole of the discharge pipe, thereby opening the sealing valve. Because the elastic telescopic rod has a certain degree of elasticity, it can ensure that the sealing valve remains open within a certain travel range when the slider approaches the mixing box. When the elastic telescopic rod is completely separated from the gate plate, the gate plate returns to its original position under the action of the spring, and the sealing valve closes.

[0041] Application in sewage treatment plants:

[0042] In sewage treatment plants, the use of elastic telescopic rods enables automated control of sealing valves. Working in conjunction with the reciprocating screw, slider, and other components, the rods precisely control the opening and closing timing of the sealing valves, ensuring that sewage and degradation liquid enter the mixing drum for thorough mixing at the predetermined ratio and interval. This automated control method not only improves the operating efficiency of the plant but also enhances its stability and reliability.

[0043] Reference Figures 1 to 2 As shown, the present invention provides a sewage treatment device for electrolytic copper foil production, comprising a preliminary mixing device and a stirring device arranged in sequence from top to bottom, the liquid outlet end of the preliminary mixing device is connected to the stirring device; the preliminary mixing device comprises a mixing box 39, the top of the mixing box 39 is connected to a degradation liquid material pipe 17 and a sewage pipe 16, the outlet ends of the sewage pipe 16 and the degradation liquid material pipe 17 are both provided with a liquid control component, the liquid control component is used to control the ratio of sewage and degradation liquid introduced into the mixing box 39, a mixing component is provided in the mixing box 39, the mixing component is transmission-coordinated with a driving member, a sealing valve is provided at the discharge end of the mixing box 39, the mixing component is transmission-coordinated with a control component, the control component is used to control the opening and closing of the sealing valve; the stirring device comprises a stirring drum 2, a stirring component is provided in the stirring drum 2, the stirring component is transmission-coordinated with the driving member, and an anti-disturbance component is provided below the stirring component.

[0044] The degradation liquid and sewage introduced into the mixing box 39 can be preliminarily mixed by the provided mixing component. The ratio of the degradation liquid and sewage introduced into the mixing box 39 can be controlled by the liquid control components respectively provided on the degradation liquid feed pipe 17 and the sewage pipe 16, thereby achieving quantitative mixing and improving the effect of the preliminary mixing. The provided control component can intermittently control the opening of the sealing valve so that the preliminarily mixed degradation liquid and sewage flow into the mixing drum 2 and are fully stirred by the stirring component. The provided anti-disturbance component can isolate the sediment to prevent it from being disturbed by the stirring component.

[0045] Furthermore, the mixing assembly includes a rotating shaft 19 rotatably connected to the mixing box 39, the rotating shaft 19 is arranged horizontally, and a plurality of stirring blades 18 are connected to the rotating shaft 19 along the circumferential direction. One end of the rotating shaft 19 passes through the side wall of the mixing box 39 and cooperates with the driving member for transmission. Two trigger members are symmetrically arranged on the rotating shaft 19, and the trigger members are arranged corresponding to the liquid control assembly. The trigger members are used to control the operation of the liquid control assembly.

[0046] In this embodiment, the driving member is a motor 22, the output shaft of the motor 22 is fixedly connected to the rotating shaft 19, and the motor 22 drives the rotating shaft 19 to rotate, thereby driving the stirring blade 18 to preliminarily mix the degradation liquid and sewage in the mixing box 39.

[0047] The rotating shaft 19 drives the trigger member to touch the liquid control component, so that the liquid control component is opened.

[0048] Furthermore, the liquid control component includes a conical tube body 40, a bracket 2 36 is connected inside the conical tube body 40, a push rod 32 is slidably connected to the bracket 2 36, the bottom end of the conical tube body 40 is connected to the orifice plate 33, the bottom end of the push rod 32 passes through the orifice plate 33, and a sealing plate 34 is fixedly sleeved on the push rod 32, the sealing plate 34 is located above the orifice plate 33, a spring 2 35 is sleeved on the push rod 32, the top end of the spring 2 35 abuts against the bracket 2 36, and the bottom end of the spring 2 35 abuts against the sealing plate 34.

[0049] The trigger member presses the push rod 32, which overcomes the elastic force of the spring 2 35 and drives the sealing plate 34 to move upward, so that the sealing plate 34 is separated from the orifice plate 33, and the seal fails. At this time, the liquid in the tapered tube 40 flows smoothly into the mixing box 39.

[0050] Furthermore, the trigger member includes a connecting rod 38 connected to the rotating shaft 19 , and one end of the connecting rod 38 away from the rotating shaft 19 is connected to a wedge block 37 .

[0051] The push rod 32 is squeezed by the inclined surface of the wedge block 37, and the wedge block 37 has a certain length, which can extend the opening time of the opening control liquid component.

[0052] Furthermore, the sealing valve includes a discharge pipe 23 connected to the bottom end of the mixing box 39, and a gate plate 24 is horizontally slidably connected to the discharge pipe 23. A through hole 11 is provided on the gate plate 24. A vertical plate 26 is provided on the side of the gate plate 24 away from the control component, and a spring 25 is elastically connected between the vertical plate 26 and the gate plate 24.

[0053] When the control assembly contacts the gate plate 24 and pushes the gate plate 24 to compress the spring 1 25, the through hole 11 on the gate plate 24 is connected to the tube hole of the discharge pipe 23, and the sealing valve is in the open state.

[0054] Furthermore, the control component includes a reciprocating screw 13 coaxially connected to the rotating shaft 19, the other end of the reciprocating screw 13 is rotatably connected to a bracket 12, the bracket 12 is connected between the mixing box 39 and the mixing drum 2, a slide rod 14 is connected between the bracket 12 and the mixing box 39, a slider 15 is slidably connected to the slide rod 14, the slider 15 is sleeved on the reciprocating screw 13, the bottom end of the slider 15 is connected to an elastic telescopic rod 10, and the elastic telescopic rod 10 is horizontally arranged.

[0055] The reciprocating screw 13 is driven to rotate by the rotating shaft 19. At the same time, under the limiting action of the slide bar 14, the slider 15 reciprocates. When the elastic telescopic rod 10 contacts the gate plate 24 and pushes the sealing valve to open, because the elastic telescopic rod 10 has a certain elasticity, it ensures that when the slider 15 approaches the mixing box 39, the sealing valve is always in the open state within a certain stroke. When the elastic telescopic rod 10 is completely separated from the gate plate 24, the gate plate 24 is reset under the action of the spring 25, and the sealing valve is closed.

[0056] Furthermore, the stirring assembly includes a fixed ring 28 rotatably connected to the inner wall of the stirring drum 2, and the outer wall of the fixed ring 28 is fixedly sleeved with an outer gear ring 9, which is transmitted and cooperated with the driving member through a transmission member. The inner wall of the fixed ring 28 is connected to a mounting plate 29, and a plurality of stirring members are provided on the mounting plate 29.

[0057] In this embodiment, the transmission member is a rotating rod rotatably connected to the inner wall of the mixing drum 2, the bottom end of the rotating rod is connected to a gear 27, the gear 27 is engaged with the outer gear ring 9, the top end of the rotating rod is connected to a driven bevel gear 21, and a driving bevel gear 20 is fixedly sleeved on the rotating shaft 19, and the driving bevel gear 20 is engaged with the driven bevel gear 21.

[0058] The fixing ring 28 is fixedly connected to the inner wall of the mixing drum 2 via the bearing 8 .

[0059] The motor 22 drives the rotating shaft 19 and the driving bevel gear 20 to rotate. The driving bevel gear 20 engages with the driven bevel gear 21 for transmission, driving the rotating rod and gear 1 27 to rotate. Gear 1 27 engages with the outer gear ring 9 for transmission, thereby realizing the rotation of the outer gear ring 9, and the outer gear ring 9 drives the stirring element to stir.

[0060] Furthermore, the stirring member includes a plurality of rotating rods 7 arranged on the mounting plate 29, and one end of a plurality of connecting rods 6 is connected to the rotating rods 7, and the other end of the connecting rods 6 is connected to a fan-shaped plate 5, and a plurality of through holes are opened on the fan-shaped plate 5.

[0061] Furthermore, the anti-disturbance component includes a partition 4 connected to the mixing drum 2 , and a plurality of conical buckets 3 are connected to the partition 4 , and the top of the conical bucket 3 is flush with the top of the partition 4 .

[0062] The sediment can enter the bottom of the partition 4 through the conical bucket 3 for isolation, and can be discharged through the discharge port set at the bottom of the mixing drum 2. A valve 1 is provided on the discharge port to facilitate the control of the discharge operation.

[0063] Furthermore, a fixing rod 31 is connected to the middle of the top of the anti-disturbance component, the mounting plate 29 is a ring structure, the top of the fixing rod 31 passes through the mounting plate 29 and is connected to gear 2 30, and multiple rotating rods 7 are arranged at equal intervals along the axial direction of the fixing rod 31, the rotating rods 7 are rotatably connected to the mounting plate 29, and the top of the rotating rod 7 is connected to gear three 41, which meshes with gear two 30.

[0064] Under the meshing of gear 3 41 and gear 2 30, the rotating rod 7 rotates, driving the sector plate 5 to rotate. This structural arrangement not only enables the stirring element to revolve along with the mounting plate 29, but also enables the stirring element to rotate, thereby achieving sufficient stirring of the degradation liquid and sewage, improving the stirring efficiency and stirring effect.

[0065] The sewage treatment device for electrolytic copper foil production provided by the present invention has the following working principle: when in use, degradation liquid and sewage are respectively introduced into the mixing box 39, the motor 22 is started, and the motor 22 drives the rotating shaft 19 and the stirring blade 18 to perform preliminary mixing. When the wedge block 37 on a trigger part is squeezed onto the top rod 32 connected to the sewage pipe 16, the top rod 32 overcomes the elastic force of the spring 2 35 and drives the sealing plate 34 to move upward, so that the sealing plate 34 is separated from the orifice plate 33, and the seal fails. At this time, the sewage in the conical tube body 40 flows smoothly into the mixing box 39. After a period of contact, the wedge block 37 separates from the top rod 32, and then the wedge block 37 on the other trigger part contacts the top rod 32 on the degradation liquid material pipe 17, and the degradation liquid enters the mixing box 39, thereby achieving the proportional introduction of sewage and degradation liquid; at the same time, the rotating shaft 19 drives the reciprocating screw rod 13 to rotate, and under the limiting action of the slide bar 14, the slider 15 makes reciprocating motion. When the elastic telescopic rod 10 contacts the gate plate 24, the sealing valve is pushed open. Because the elastic telescopic rod 10 has a certain elasticity, it is ensured that when the slider 15 approaches the mixing box 39, within a certain stroke, the sealing valve is always in an open state, and the preliminarily mixed liquid enters the mixing drum 2. When the elastic telescopic rod 10 is completely separated from the gate plate 24, the gate plate 24 is reset under the action of the spring 25, and the sealing valve is closed. The revolution and rotation of the stirring member are driven by the rotating member to fully stir the sewage and degradation liquid. The sediment enters the bottom of the partition plate 4 through the conical bucket 3 for isolation, and can be discharged through the discharge port set at the bottom end of the mixing drum 2.
