Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of PCB board industrial wastewater treatment, in particular to a device specially used for waste etching liquid transfer. BACKGROUND

[0002] Etching is an important process in PCB (printed circuit board) manufacturing. A large amount of high-concentration copper-rich etching waste liquid is generated in the production process of circuit board factories. The etching waste liquid is a dangerous liquid waste containing a large amount of copper, chlorine and other pollutants. In addition, copper ions and chlorine ions in the etching waste liquid also have high recycling value. Therefore, the etching waste liquid is usually recycled and regenerated. Chinese patent CN217324310U discloses a full-automatic etching liquid transfer barrel device, which includes a box body, a liquid inlet pipe connected to one side of the top end of the box body, a feed electric valve arranged on the liquid inlet pipe, an extension hose connected to the end of the liquid inlet pipe away from the box body, an adapter connected to the end of the extension hose away from the liquid inlet pipe, a liquid outlet pipe connected to the other side of the bottom end of the box body, a discharge electric valve arranged on the liquid outlet pipe, a feeding pump connected to the end of the liquid outlet pipe away from the box body, and first, second and third perforated partitions vertically installed in the box body from the liquid outlet pipe to the liquid inlet pipe. The device solves the problems of equipment corrosion and environmental pollution caused by material overflow during etching liquid transfer.

After a period of time, the perforations of the perforated partitions are easily blocked by residues, causing poor liquid flow. In addition, the filter needs to be cleaned manually at regular intervals.

[0020] The box 1 is provided with an overflow plate 14, so that the falling liquid can be precipitated before flowing to the liquid outlet pipe 3. The upper side of the overflow plate 14 is provided with a baffle 15 fixedly connected with the box 1, so as to avoid that the liquid or residue is thrown to the left side of the overflow plate 14 during the rotation of the filter cylinder 6. The box 1 is provided with a flow guide seat 16 communicated with the liquid outlet pipe 3. The flow guide seat 16 is rotatably provided with a rotating shaft 17. The outer side of the rotating shaft 17 is sleeved with an impeller 18 matched with the flow guide seat 16. When the liquid is extracted by the feeding pump, the flowing liquid drives the rotating movement of the impeller 18, and the impeller 18 drives the synchronous rotating movement of the rotating shaft 17. The second rotating disc 190 is rotatably arranged at one end of the supporting shaft 7 penetrating through the outer side of the box 1. The outer side of the supporting shaft 7 outside the second rotating disc 190 is fixedly provided with a ratchet wheel 191. The second rotating disc 190 is rotatably provided with a ratchet pawl 192 on one side. The ratchet pawl 192 and the supporting shaft 7 are connected with a tension spring 193. The two ends of the rotating shaft 17 penetrate through the outer side of the box 1 and are sleeved with a gear 195. The front and rear sides of the box 1 are both provided with a pin shaft 196. The outer side of the pin shaft 196 is sleeved with a transmission disc 197. The outer side of the transmission disc 197 is provided with a gear slot matched with the gear 195. The second rotating disc 190 and the transmission disc 197 are hingedly connected with a third push rod 194. The supporting rod 130 is sleeved with a rocker arm 198 at one end penetrating through the outer side of the box 1. The rocker arm 198 and the second rotating disc 190 are movably connected with a pull rod 199. The rotating shaft 17 drives the synchronous movement of the two gears 195. The meshing transmission between the gear 195 and the gear slot on the transmission disc 197 drives the rotating movement of the transmission disc 197. The transmission of the third push rod 194 drives the synchronous rotation of the second rotating disc 190. The ratchet pawl 192 rotates along the outer side of the ratchet wheel 191. The elastic tension of the tension spring 193 makes the ratchet pawl 192 finally clamped into the clamping groove of the ratchet wheel 191. At the same time, the second rotating disc 190 drives the pull rod 199 to pull the rocker arm 198, so that the supporting rod 130 rotates, and then the first push rod 132 and the impact ball 134 are away from the filter cylinder 6 at the same time. When the third push rod 194 passes through the highest point of the transmission disc 197, the third push rod 194 drives the second rotating disc 190 to rotate reversely, so that the filter cylinder 6 rotates rapidly. When the filter cylinder 6 is started instantaneously, the liquid remaining on the residue in the filter cylinder 6 is thrown out, and the supporting rod 130 reversely rotates.

[0021] In the present embodiment, as shown in Figure 6 The outer side of the impact ball 134 is sleeved with a corrosion-resistant rubber sleeve 20. The impact of the impact ball 134 on the filter cylinder 6 is buffered by the corrosion-resistant rubber sleeve 20, so as to avoid the damage of the filter cylinder 6 due to the impact.

[0022] In the present embodiment, as shown in Figure 2As shown, the box 1 is symmetrically provided with a blocking frame 21, and the upper surface of the blocking frame 21 is 3-5 mm higher than the upper end of the overflow plate 14. The blocking frame 21 blocks the ripples caused by the filtrate falling into the liquid surface below, avoiding the adverse effects of overflow on the liquid.

[0023] In the present embodiment, as shown, Figure 2 The material guide plate 11 is composed of a vertically arranged fixed plate 110 and an inclined guide plate 111, and the lower end of the guide plate 111 is placed above the inner cavity of the slag collecting box 12 beyond the fixed plate 110, so that the slag discharged from the filter cartridge 6 can directly slide into the slag collecting box 12 from the guide plate 111, avoiding the corrosion liquid from leaking to the outside of the slag collecting box 12.

[0024] Working principle: when working, the waste etching liquid flowing into the liquid inlet pipe 2 is shunted by the shunt pipe 4, so that the flow rate of the liquid is slowed down, thereby avoiding the adverse effects of the flow rate of the liquid on the filtration of the liquid. The discharged waste etching liquid is filtered by the filter cartridge 6, and the filtered waste etching liquid is discharged from the leakage hole of the filter cartridge 6. The liquid is blocked by the overflow plate 14, so that the filtered waste etching liquid is precipitated and filtered. The liquid is extracted by the feeding pump, so that the flowing liquid drives the impeller 18 to rotate, and the impeller 18 drives the rotating shaft 17 to rotate synchronously. The rotating shaft 17 drives the two gears 195 to rotate synchronously, and the meshing transmission between the gears 195 and the tooth grooves on the transmission disc 197 drives the transmission disc 197 to rotate. The third push rod 194 drives the second rotating disc 190 to rotate synchronously, so that the pawl 192 rotates along the outside of the ratchet wheel 191, and the elastic tension of the tension spring 193 makes the pawl 192 finally clamped into the clamping groove of the ratchet wheel 191. At the same time, the second rotating disc 190 drives the pull rod 199 to pull the rocker arm 198, so that the supporting rod 130 rotates, and then the first push rod 132 and the impact ball 134 move away from the filter cartridge 6 at the same time. When the third push rod 194 passes the highest point of the transmission disc 197, the third push rod 194 drives the second rotating disc 190 to rotate reversely, so that the pawl 192 drives the ratchet wheel 191 to rotate, thereby driving the supporting shaft 7 to rotate rapidly with the filter cartridge 6. When the filter cartridge 6 is started instantaneously, the liquid remaining on the slag in the filter cartridge 6 is thrown out, and the supporting rod 130 rotates reversely. The supporting rod 130 drives the first push rod 132 to push the opened push plate 10 to close, and at the same time, the supporting rod 130 drives the impact ball 134 on the swing rod 133 to impact the filter cartridge 6, so that the filter cartridge 6 vibrates to make the slag in the leakage hole be shaken out. At the same time, the swing rod 133 drives the sliding sleeve 136 to rotate around the supporting rod 130, and the swing rod 133 drives the top plate 135 to move horizontally through the guiding effect of the guide rod 138, so that the second push rod 137 pushes the push plate 10 to open.
