Description

Technical Field

[0001] The invention relates to the technical field of reclaimed water reuse, in particular to a reclaimed water reuse system for a PCBA online cleaning machine. Background Art

[0002] During the production process of PCBA boards, solder paste, solder wire, etc. need to be used for welding. These auxiliary materials will remain on the PCBA board, so the PCBA board needs to be cleaned. In order to meet the needs of environmental protection, the existing PCBA online cleaning machine needs to recycle the cleaned water. In the water reuse system, the cleaning of impurities contained in the water is a very critical step. It is necessary to add reagents to make the impurities contained in the water form precipitation and accumulate at the bottom of the treatment device. Traditional treatment devices clean the precipitation regularly, that is, after a certain amount of precipitation accumulates at the bottom of the treatment device, it is cleaned. Since the precipitation is at the bottom of the device, it is troublesome to clean, time-consuming and labor-intensive, which makes the work intensity of the staff greater. In addition, the precipitation at the bottom of the device is easy to block the drain outlet when draining, resulting in poor drainage. Summary of the invention

[0015] Compared with the prior art, the invention has the following advantages:

[0016] 1. The interior of the impurity cleaning pool is divided into an inlet chamber and a drainage chamber. Impurities are precipitated in the inlet chamber. After precipitation is completed, the electric telescopic rod is started to drive the sedimentation carrier plate to move upward, which can drive the sediment to move out of the impurity cleaning pool. At the same time, the water on the upper side of the sedimentation carrier plate is discharged from the permeable filter plate to separate water and sediment, which is convenient for cleaning the sediment. At the same time, as the sedimentation carrier plate moves upward, it will make the closed plug cover unlocked, which is convenient for water discharge.

[0017] 2. When the sedimentation carrying plate moves to the upper port of the impurity cleaning tank, the closed plug cover is in an unlocked state at this time, so that the closed plug cover will be pushed to move under the action of water, thereby making the drain pipe in an open state, which is convenient for the discharge of water, and as the closed plug cover moves, it will drive the plug-in matching rod to move upward. As the plug-in matching rod moves upward, when the positioning movable plate passes over the limit support vertical plate, the counterweight ring moves downward under the action of gravity, thereby making the positioning movable plate overlap the limit support vertical plate to fix the closed plug cover. In this way, when the water is almost drained, the drain pipe will not be closed due to insufficient impact force of the water, thereby ensuring that the water can be drained smoothly, and the sediment at this time is on the upper side of the impurity cleaning tank, which is more convenient to clean, and realizes the simultaneous drainage and cleaning, which not only reduces the work intensity of the staff but also improves the utilization efficiency of the impurity cleaning tank, and there is no need to wait for the water to be drained before cleaning the sediment.

[0018] 3. In addition, when the plug-in mating rod moves upward, it will drive the centralized pushing plate to move toward each other under the action of the second connecting hinge rod, so that the sediment on the sedimentation bearing plate can be pushed under the action of the centralized pushing plate, so that it can be piled together, which is more convenient for the staff to clean up.

[0044] The treated reclaimed water enters the water inlet chamber 181 through the water inlet pipe 13. The impurities are concentrated in the water inlet chamber 181 under the action of the permeable filter plate 2. The impurities in the water are precipitated by adding precipitation solution into the water inlet chamber 181. When the treated water needs to be discharged, the electric telescopic rod 12 is started to drive the precipitation carrier plate 3 to move upward. Under the action of the precipitation carrier plate 3, the precipitation will be driven to move upward. At the same time, the water on the upper side of the precipitation carrier plate 3 is discharged through the permeable filter plate 2 until the upper end surface of the precipitation carrier plate 3 is flush with the plane where the pool mouth of the impurity cleaning pool 1 is located. The precipitation carrier plate 3 stops, and in the process of the precipitation carrier plate 3 moving upward, the push rod 34 will be The inclined hollow frame 42 is in contact with each other, so that the push rod 34 will push the matching movable plate 4 to move, so that the limit pressure plate 45 is no longer pressed on the limit vertical plate 64, so that the plug-in matching rod 6 loses its limit, and the closed plug cover 5 is in an active state at this time.

Even if the water in the impurity cleaning pool 1 is not enough to overcome the gravity of the plug-in matching rod 6, the drain pipe 16 will not be closed, ensuring the smooth discharge of water. In the process of the plug-in matching rod 6 moving upward, the two concentrated pushing plates 7 will be driven to move toward each other under the action of the second connecting hinge 67. In this way, the concentrated pushing plates 7 will push the sediment to pile up together, which is more convenient. When cleaning, the sediment can be cleaned while draining water, and the sediment is on the upper side of the impurity cleaning pool 1, which is convenient for cleaning. In addition, when the plug-in matching rod 6 moves upward, the end face of the limit pressure plate 45 contacts the limit vertical plate 64. When the cleaning is completed, the electric telescopic rod 12 drives the sediment bearing plate 3 to reset, and then pulls the counterweight ring 8 upward so that the positioning movable plate 83 is no longer overlapped on the limit support vertical plate 14, so that the plug-in matching rod 6 can move downward. When the limit vertical plate 64 moves to the bottom of the limit pressure plate 45, the limit pressure plate 45 is pressed on the limit vertical plate 64 again under the action of the connecting spring 431, so that the drain pipe 16 is closed and the closed plug cover 5 is locked at the same time.
