Description

Technical Field

[0001] This utility model relates to the field of waste liquid collection, specifically a circuit board etching waste liquid collection device. Background Technology

[0002] The current process of collecting PCB etching waste liquid requires several processing steps. The existing recycling device has a relatively simple structure. After the recycling reaction, the copper particles produced accumulate randomly at the bottom of the recycling cylinder, making it difficult for users to remove them quickly and easily, resulting in poor practicality of the device.

[0003] CN214655165U discloses a circuit board etching waste liquid recovery device, including a fixing mechanism and a recovery cylinder fixedly connected to the upper end of the fixing mechanism. The top of the recovery cylinder is open. The bottom of the fixing mechanism is equipped with a stirring mechanism adapted to the recovery cylinder. The output end of the stirring mechanism extends through the fixing mechanism and the bottom of the recovery cylinder to the inner side of the recovery cylinder. The top of the recovery cylinder is detachably connected to an end cap. The top of the end cap has a liquid inlet in the middle. The bottom of the end cap has a copper particle recovery mechanism. By setting the copper particle recovery mechanism, during the reaction process, the copper particles condensed in the waste liquid fall onto the cone and slide outwards into the recovery tank under the influence of gravity, thus achieving recovery. Compared with traditional circuit board etching waste liquid recovery devices, this device is more convenient and faster for copper particle recovery, easier for users to operate, and more practical. However, this patent still has the following problems in actual use:

[0004] When extracting copper particles, the above-mentioned device requires the entire recycling tank to be raised above the recycling cylinder, and then the scattered copper particles distributed in the recycling tank are manually collected. Since the device itself is usually large, external suspension equipment is required to assist in raising the recycling tank, or workers need to climb to the top of the recycling cylinder to operate manually. The operation cost is high and the safety is low. In addition, manually collecting the scattered copper particles is troublesome and time-consuming.

[0005] A circuit board etching waste liquid collection device is proposed to solve the problems mentioned above. Utility Model Content

[0026] A discharge assembly 2 is provided at the bottom of the interior of the processing box 1. The discharge assembly 2 includes a copper discharge hole 202 rotatably connected to the bottom surface of the processing box 1. A bent connecting rod 203 is fixedly connected inside the copper discharge hole 202. A slanted plate 204 is fixedly connected to the other end of the bent connecting rod 203. The slanted plate 204 is set as a slanted plate and fits the surface of the conical rotating block 201.

[0027] The copper discharge hole 202 has an extension tube 205 on its outer side. The bottom of the extension tube 205 is fixedly connected to a collection chamber 207. The side opening of the collection chamber 207 is provided with a sealing mechanism 3. The inside of the collection chamber 207 is equipped with a collection drawer 208. The bottom of the collection drawer 208 is fixedly installed with a filter screen 214. The bottom of the collection chamber 207 is fixedly installed with a valve pipe 210. The valve pipe 210 is a prior art pipe with a valve. This pipe is connected to the subsequent wastewater treatment device. The side of the collection chamber 207 has a side opening.

[0028] A drive motor 206 is fixedly connected to the bottom of the support. The output end of the drive motor 206 extends into the processing box 1 and is fixedly connected to the bottom of the conical rotating block 201. A vertical shaft 211 is fixedly connected to the middle of the top surface of the conical rotating block 201. Several stirring rollers 212 are symmetrically fixedly connected to the outside of the vertical shaft 211. A scraper 213 is fixedly connected to the other end of the stirring roller 212. The scraper 213 is in contact with the inner wall of the processing box 1. A stabilizing crossbar is rotatably connected to the top of the vertical shaft 211. The stabilizing crossbar is fixedly connected to the inner wall of the processing box 1.

[0029] A square slot is provided at the bottom of the inside of the collection drawer 208. The collection drawer 208 is fixed inside the square slot. A handle 209 is connected to the outside of the side of the collection drawer 208 near the opening of the collection compartment 207.

[0030] The collection chamber 207 is inserted into the extension tube 205 and fits against the inner wall of the extension tube 205. The extension tube 205 is fixedly connected to the outer wall of the processing box 1. The side opening of the collection chamber 207 is located near the side of the collection chamber 207 where the handle 209 is installed.

[0031] The sealing mechanism 3 includes a pair of mounting plates 301, one mounting plate 301 is connected to the outside of the collection chamber 207, and the other mounting plate 301 is fixedly connected to the outside of a screw ring 306.

[0032] Both mounting plates 301 are fixedly connected to trapezoidal strips 302 and bends 303 on their outer sides. The trapezoidal strips 302 and bends 303 on the outer sides of different mounting plates 301 are respectively engaged and connected. During the engagement of the trapezoidal strips 302 and bends 303, the two mounting plates 301 are pulled closer to each other, thereby increasing the sealing between them through the through hole 305 while quickly connecting them.

[0034] Working principle: Before using this circuit board etching waste liquid collection device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, the drive motor 206 first starts the conical rotating block 201 to rotate the vertical shaft 211. As the copper material settles, it moves down the inclined surface of the conical rotating block 201 and rolls with the rotation of the liquid. Driven by the conical rotating block 201, it slowly rolls along the bottom inner wall of the processing tank 1. When it passes through the copper discharge hole 202, it enters the extension tube 205 through the copper discharge hole 202 and then falls into the collection drawer 208 inside the collection chamber 207 under gravity. Then, it is only necessary to discharge the waste liquid after the reaction through the valve pipe 210. The two mounting plates 301 can be separated by rotating and disassembling the mounting plate 301. Finally, the collection drawer 208 along with the copper material inside can be taken out from the collection chamber 207, which is convenient for cleaning the copper material. It is not necessary to open the top cover and extract the internal device, which reduces the difficulty of operation.

[0035] When the two mounting plates 301 approach each other and rotate, the bending fold 303 will first contact the inclined surface of the trapezoidal strip 302 and slide along the inclined surface until it moves to the plane of the trapezoidal strip 302. During this process, the two mounting plates 301 approach each other and cause the rubber sealing gaskets 304 to be squeezed against each other to form a seal.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
