Description
Technical Field

[0002] In the circuit board etching process, acidic or alkaline etching solutions are usually used to remove the copper foil on the circuit board to form the required circuit pattern on the circuit board. Acidic etching solutions are widely used because of their small side etching, easy to control rate and easy regeneration. Acidic etching waste liquid is formed after the acidic etching solution is used. Acidic etching waste liquid is a strong acid solution containing a large amount of heavy metals (such as copper chloride). Direct discharge will cause environmental pollution. Therefore, the acidic etching waste liquid needs to be treated before discharge. The treatment of acidic etching waste liquid is usually carried out by electrolysis. During the electrolysis process, the cathode will produce recyclable elemental electrolytic copper, and the anode will produce harmful chlorine gas. The chlorine gas that is not dissolved in the acidic etching solution also needs to be treated.
[0003] Chlorine is usually treated with ferrous chloride solution, and the preparation of ferrous chloride solution is generally carried out in an iron dissolving tank, in which ferric chloride solution is contained. When preparing ferrous chloride solution, iron material is usually placed in a plastic frame, and the iron material and the plastic frame are placed in the iron dissolving tank together, and then the ferric chloride solution is sprayed on the surface of the iron material through air to make the iron material and the ferric chloride solution react. The reaction rate of this setting method is slow, and the iron materials are stacked together in the plastic frame, and the surface of the iron materials cannot fully contact with the ferric chloride solution, which is not conducive to the generation of ferrous chloride solution and the absorption of chlorine.

Detailed Description of the Invention
[0026] The present invention will be further described in detail below in conjunction with the drawings and embodiments, so as to make the purpose, technical solution and advantages of the present invention clearer.

The iron materials are inserted vertically into the first accommodating grooves and horizontally into the second accommodating grooves. After placing the iron materials, under the action of the first partition plates and the second partition plates, the surfaces of adjacent iron materials can be prevented from contacting. Compared with the way of stacking iron materials in the iron loading structure, the surface of each iron material in the present utility model can fully contact with the solution, accelerating the reaction rate between the iron material and the solution. Under the combined action of the first accommodating grooves and the second accommodating grooves, more iron materials can be accommodated, and during the reaction process between the iron materials and the ferric chloride solution, the number of times of adding iron materials can also be reduced.
[0029] The first iron loading box 1 is arranged above the second iron loading box 2. The first iron loading box 1 and the second iron loading box 2 can be welded or detachably connected.

The first partition plates and the first side plates can be welded, integrally formed, or detachably connected). The bottom of the first partition plates 13 can be connected to the first bottom plate 12 or can be spaced apart from the first bottom plate 12 by a certain distance (for example, the distance between the bottom of the first partition plate and the first bottom plate is 1 - 8 cm). The water inlet holes are respectively arranged on the first side plates 11 and the first bottom plate 12.
[0031] The overall shape of the second iron loading box 2 is a prismatic structure, including a second top plate 21 and a second bottom plate 22 that are parallel to each other.

The water inlet holes are respectively arranged on the second top plate 21, the second bottom plate 22, the second side plate one 23, and the second side plate two 24.
[0032] When the first iron loading box 1 and the second iron loading box 2 are welded, the first bottom plate 12 and the second top plate 21 are welded. When the first iron loading box 1 and the second iron loading box 2 are detachably connected, the first bottom plate 12 and the second top plate 21 can be connected by screws, or the first iron loading box 1 and the second iron loading box 2 can be connected by a connecting member 5 (refer to Figure 3 ). Refer to Figure 4 , the overall shape of the connecting member 5 is a prismatic structure. The connecting member 5 includes a side wall 51. At the top and bottom of the side wall 51, there are respectively connecting plates 52. The connecting plates 52 are connected to the inner surface of the side wall 51.

[0034] A baffle 6 is also arranged on the second iron loading box 2. Refer to Figure 5, a baffle 6 is arranged at the opening position of the second iron loading box 2. After the iron materials are loaded into the second iron loading box 2, the baffle 6 can block the opening to prevent the iron materials from falling out of the second iron loading box 2. A baffle opening is also arranged on the first second side plate 23 on one side of the opening of the second iron loading box 2. The width of the baffle opening is adapted to the width of the baffle 6, and the baffle 6 is inserted into the second iron loading box 2 from the baffle opening. The baffle 6 is of an L-shaped structure, including a first baffle 61 and a second baffle 62. The first baffle 61 is inserted into the second iron loading box 2 from the baffle opening.

An adjusting bolt 7 (refer to Figure 5 , Figure 6 ) is arranged in the screw hole of the second baffle 62, and the adjusting bolt 7 can stably fix the baffle 6 in the second iron loading box 2.
[0035] Baffle grooves are arranged on both the second top plate 21 and the second top plate 22. The width of the baffle groove is adapted to the thickness of the first baffle 61, and the first baffle 61 can slide in the baffle groove. Water inlet holes are also arranged on the first baffle 61 to facilitate the ferric chloride solution in the iron melting tank to enter the second iron loading box 2.
[0036] One or more hooks 4 are also arranged on the first iron loading box 1. The hooks 4 are arranged at the top of the first iron loading box 1. The hooks 4 are welded or detachably connected to the first iron loading box 1. When arranging the iron loading structure in the iron melting tank, the hooks 4 can hang the iron loading structure in the iron melting tank so that the iron materials in the iron loading structure are in contact with the ferric chloride solution in the iron melting tank.
[0037] Both the first iron loading box 1 and the second iron loading box 2 are made of corrosion-resistant materials, such as metal titanium, PP materials, etc. When the first iron loading box 1 and the second iron loading box 2 need to conduct electricity, it is preferably made of metal titanium. During the application process, more second iron loading boxes 2 can be set. Adjacent second iron loading boxes 2 are connected by a connecting piece 5 so that the first iron loading box 1 and multiple second iron loading boxes 2 are connected into an integral structure; after setting iron materials in the first iron loading box 1 and the second iron loading box 2 respectively, the contact area between the iron materials and the ferric chloride solution is further increased, and the conversion efficiency of the conversion of ferric ions to ferrous ions is increased.
[0038] When multiple second iron loading boxes 2 are set, the opening directions of adjacent second iron loading boxes 2 can be the same, or opposite or perpendicular to each other (preferably perpendicular to each other) to facilitate the reaction between the iron materials and the ferric chloride solution.

Water inlet holes can also be arranged on the second partition plate 25 to facilitate the ferric chloride solution to enter the adjacent second accommodating groove through the second partition plate 25 to make the iron materials react with the ferric chloride solution.
[0040] The number and size of the water inlet holes are set according to requirements. The water inlet holes can be circular through holes with a diameter of 3 to 8 mm, or rectangular or circular through holes with larger sizes (such as rectangular through holes with a width of 5 to 10 cm). When the size of the water inlet holes is larger, a filter screen 3 (preferably made of titanium mesh) can be provided at the position of the water inlet holes. The filter screen 3 is respectively fixed on the inner surface of the first iron loading box 1 and the inner surface of the second iron loading box 2.
