Description

Technical Field

[0001] The present application relates to the technical field of circuit boards, and specifically to a device for treating waste water from circuit board cleaning. Background Art

[0002] A circuit board is a printed circuit board with highly integrated electronic components, which is widely used in electronic products such as mobile phones and laptop computers, and can improve the space utilization rate of products. After processes such as cutting and welding, the circuit board usually needs to be cleaned, and the waste water after cleaning contains various metal impurities. Direct discharge will seriously pollute the environment, so it is often necessary to treat and filter the waste water.

[0003] The Chinese utility model patent with the publication number CN212425531U discloses an automatic treatment device for waste water in the production of multi-layer printed circuit boards, which relates to the technical field of printed circuit boards and related devices. It includes a motor and a left-opening frame. A filter screen is connected inside the left-opening frame. One end of the left-opening frame close to the water tank is adhesively bonded with a sealing ring by glue. One end of the left-opening frame close to the water tank is symmetrically welded with connecting ears up and down. Bolts are threadedly connected to the connecting ears, and the connecting ears are installed on the water tank through the bolts. An inlet is provided at one end of the water tank close to the left-opening frame. The lower end surface of the motor is connected with a rotating shaft, and the rotating shaft is rotationally connected with the top cover through a bearing. By setting the magnet bar, motor, left-opening frame, connecting ears and bolt structure, the user can control the present utility model to screen magnetic impurities in the sewage, and the user can disassemble the left-opening frame, thereby facilitating the user to clean the filter screen.

[0004] A motor is provided in the device, and the lower end of the motor is connected with a rotating shaft. When treating waste water, the waste water enters the water tank through the water inlet pipe, and then the motor drives the rotating shaft to rotate, so that the magnet bar below the rotating shaft adsorbs metal impurities in the waste water. After that, when discharging through the opening frame, it is filtered again by the filter screen. However, when cleaning the impurities on the magnet bar and the filter screen, it is necessary to disassemble the top cover and the opening frame, and the operation is cumbersome and the cleaning efficiency is not high.

The staff starts the motor, so that the motor drives the stirring roller to rotate, thereby realizing full stirring of the waste water inside the storage cavity.

[0010] Preferably, the stirring roller is located above the filter frame and the guide plate, so that when the filter screen filters the waste water, the stirring of the stirring roller can avoid impurities from adsorbing on the guide plate and ensure effective filtration of the waste water.

[0011] Preferably, a group of inclined plates are respectively fixedly arranged on both sides of the bottom of the storage cavity. The drain pipe is located between the two groups of inclined plates. The waste water flowing down through the filter screen is stored between the two groups of inclined plates. The arranged inclined plates realize complete discharge of the waste water and avoid waste water remaining in the box body.

[0023] Such as Figures 1 - 3As shown in the figure, the embodiment of the present utility model discloses a device for treating waste water from circuit board cleaning, which includes a box body 1 and a stirring mechanism. There is a storage cavity 101 inside the box body 1. There is a feed port 2 communicating with the storage cavity 101 at the top of the box body 1. A flow guide plate 3 is fixedly arranged obliquely below the feed port 2 in the storage cavity 101. There is a through hole on the side of the box body 1 communicating with the storage cavity 101. A filter frame 4 is slidably arranged in the through hole. One end of the filter frame 4 away from the through hole abuts against the lower part of the flow guide plate 3. A filter screen 401 is fixedly arranged at the top of the filter frame 4 in the storage cavity 101. A baffle 5 is slidably arranged at the bottom of the filter screen 401 of the filter frame 4. A drain pipe 102 communicating with the storage cavity 101 is arranged at the bottom of the box body 1. The stirring mechanism is arranged on the box body 1.

[0024] In at least one embodiment, the stirring mechanism includes a motor and a stirring roller 6. The motor is fixedly arranged outside the box body 1. The stirring roller 6 is located in the storage cavity 101 and is rotatably connected with the box body 1. The output shaft of the motor is fixedly connected with one end of the stirring roller 6. The staff starts the motor, so that the motor drives the stirring roller 6 to rotate, thereby realizing full stirring of the waste water in the storage cavity 101.

[0025] In at least one embodiment, the stirring roller 6 is located above the filter frame 4 and the flow guide plate 3, so that when the filter screen 401 filters the waste water, the stirring of the stirring roller 6 can avoid impurities adsorbing on the flow guide plate 3, ensuring effective filtration of the waste water.

[0026] In at least one embodiment, a group of inclined plates 7 are respectively fixedly arranged on both sides of the bottom of the storage cavity 101. The drain pipe 102 is located between the two groups of inclined plates 7. The waste water flowing down through the filter screen 401 is stored between the two groups of inclined plates 7. The set inclined plates 7 realize complete discharge of the waste water, avoiding waste water remaining in the box body 1.

[0027] In at least one embodiment, a slider 402 is fixedly arranged on the side of the filter frame 4. The inner wall of the storage frame is provided with a chute matched with the slider 402. The slider 402 is set to further limit the filter frame 4, ensuring the stability of the sliding of the filter frame 4.

[0028] In at least one embodiment, a clamping groove is arranged on the side of the flow guide plate 3. One end of the filter frame 4 away from the through hole is embedded in the clamping groove. A sealing strip 403 is arranged at one end of the filter frame 4 in the clamping groove. By embedding one end of the filter frame 4 in the clamping groove, the stability of the filter frame 4 is ensured. The set sealing strip 403 can avoid waste water directly seeping out from the clamping groove.

[0029] In at least one embodiment, a transparent observation window 8 is arranged at the top of the box body 1. The staff can observe the waste water treatment state in the box body 1 through the observation window 8, and the operation is convenient.

[0030] When treating the wastewater after cleaning the circuit board, the staff transports the wastewater to the storage chamber 101 through the feed port 2 on the top of the box body 1, and then the wastewater entering the storage chamber 101 flows downward through the inclined guide plate 3, and the wastewater is isolated above the storage chamber 101 through the filter frame 4 on one side of the box body 1. Then, the treatment reagent is added to the wastewater through the feed port 2 to fully react the elements in the wastewater that may cause pollution to the environment to avoid pollution to the environment after discharge. When the reaction is completed, the staff slides the baffle 5 at the bottom of the filter frame 4 to disengage the filter screen 401 on the filter frame 4 to seal it, so that the wastewater can be discharged. The wastewater flows through the filter screen 401 to the bottom of the storage chamber 101. At this time, the filter screen 401 will adsorb and isolate the impurities in the wastewater, and finally enter the bottom of the storage chamber 101 and be discharged from the drain pipe 102. The stirring mechanism on the box body 1 can stir the wastewater in the storage chamber 101 to make it fully react and be effectively discharged. When it is necessary to clean the impurities on the filter screen 401, the staff will slide the filter frame 4 along the through hole to disengage it from the abutment with the guide plate 3 and finally from the box body 1. After that, the impurities on the filter screen 401 can be cleaned. After the cleaning is completed, the filter frame 4 can be inserted into the through hole. The operation is convenient and the cleaning efficiency is improved.
