Compared with the prior art, the present invention has the following advantages:

1. Through the coordination of the linkage block and the fixed block, each time the phosphating steel plate is taken out from the phosphating solution, the frame and the filter screen 1 can be linked to move upward to remove the impurities in the phosphating solution in time, which greatly reduces the interference to the phosphating operation caused by the gradual accumulation of impurities. At the same time, the cleaning process of the device is carried out together with the steel plate removal operation. Compared with the existing device, there is no need to suspend the phosphating process, which is conducive to improving efficiency. At the same time, the phosphating solution that flows into the storage box together with the impurities can flow back to the box body 1 through the transparent slots 3 and 4 to avoid waste;

Second, during the rising process of the frame and the filter screen 1, the phosphating liquid is guided through the surface of the inverted V-shaped frame, so that the phosphating liquid can slide the impurities remaining on the filter screen 1 along the mesh surface of the filter screen 1 to the end area of the filter screen 1 with the lowest vertical height in advance, so that the impurities can quickly fall into the storage box for collection, which is conducive to improving efficiency;

3. The phosphating liquid flows out from the transparent groove five to the front and rear sides of the frame, and the impurities remaining on the front and rear sides of the frame are flushed into the storage box for collection, thereby avoiding the problem that the impurities remaining on the front and rear sides of the frame are difficult to slide down. In addition, the input end of the pipeline three is always located below the filter one, so that the filter one can also prevent impurities from flowing into the pipeline three to block it. At the same time, the guide plate diagonally guides the phosphating liquid, thereby stirring the phosphating liquid, so that the various components in the phosphating liquid are evenly distributed, which is beneficial to improving the uniformity of phosphating of the steel plate.

Each filter screen 12 is connected to the corresponding storage box 11 via a buckle, so that the filter screen 12 can be manually disassembled and replaced.

The discharge component includes a pipe 201 and a valve 202; the pipe 201 is connected to the box body 1 and flange-connected; the valve 202 is installed on the pipe 201, and the solution in the box body 1 is discharged through the pipe 201.

Each storage box 11 is provided with a transparent slot three 94; the box body 1 is provided with two transparent slots four 95, and the transparent slot four 95 is connected with the corresponding transparent slot three 94, and the solution in the storage box 11 flows back into the box body 1 through the transparent slot three 94 and the transparent slot four 95.

First, the connecting plate 2 is fixed on the external conveying mechanism, and the external drainage pipe is connected to the pipeline 201. The inside of the box 1 is filled with phosphating liquid, and the liquid level of the phosphating liquid is lower than the transparent tank 95. The steel plate is fixed on the fixture 3 in a vertical state manually or by an external feeding mechanism, and then the connecting plate 2 and the parts thereon are driven to move by the external conveying mechanism, and the steel plate is conveyed to the preceding station for pretreatment operation. When the pretreatment of the steel plate is completed, the connecting plate 2 and the parts thereon are driven by the external conveying mechanism. The steel plate is conveyed to the top of the box body 1, and then the external conveying mechanism drives the connecting plate 2 and the parts thereon to move downward, immersing the steel plate in the phosphating solution of the box body 1, and phosphating the steel plate. At the same time, the connecting plate 2 drives the round rod 9 and the fixed block 10 to move downward, so that the fixed block 10 passes through the groove 91, and the fixed block 10 moves vertically to below the linkage block 7, and then the motor 8 drives the fixed block 10 to rotate forty-five degrees, so that the round rod 9 and the fixed block 10 clamp the linkage block 7.

The impurities produced by phosphating fall to the upper side of the filter screen 5. After the phosphating is completed, the connecting plate 2 and the parts thereon are driven upward by the external conveying mechanism to move the phosphating steel plate out of the box body 1. At the same time, the connecting plate 2 drives the round rod 9 and the fixed block 10 to move upward, the fixed block 10 drives the linkage block 7 to move upward, and the linkage block 7 drives the frame 4 and the filter screen 5 to move upward, so that the frame 4 contacts the magnet on the end of the guide plate 6, and the frame 4 is sucked tightly by the magnet on the guide plate 6. At this time, the front and rear sides of the frame 4 are respectively connected to the two transparent The grooves 1 92 are aligned, the filter screen 1 5 is removed from the phosphating solution, and the impurities are filtered out of the phosphating solution, and then the impurities slide obliquely downward along the surface of the filter screen 5, and then slide into the storage box 11 through the transparent grooves 1 92 and 2 93, and the impurities are collected by the storage box 11, and then the motor 8 drives the round rod 9 and the fixed block 10 to rotate, so that the fixed block 10 moves to the bottom of the groove 91, and then the external conveying mechanism drives the connecting plate 2 and the parts thereon to continue to move upward, so that the fixed block 10 passes through the groove 91 upward and moves away from the linkage block 7.

When the next phosphating operation is performed, the fixed block 10 is re-inserted into the lower side of the linkage block 7, and then the linkage block 7 and the parts thereon are pushed downward by the cooperation of the round rod 9 and the fixed block 10, so that the frame 4 is separated from the magnet on the linkage block 7 and moves to the bottom of the inner side of the box body 1, and then the above operation is repeated to phosphate the steel plate. When in use, the linkage block 7 and the fixed block 10 cooperate so that each time the phosphated steel plate is taken out of the phosphating solution, the frame 4 and the filter screen 5 can be linked to move upward to remove impurities in the phosphating solution in time, which greatly reduces the interference with the phosphating operation caused by the gradual accumulation of impurities. At the same time, the cleaning process of the device is carried out together with the steel plate removal operation. Compared with the existing device, there is no need to suspend the phosphating process, which is conducive to improving efficiency.

When the front and rear sides of the frame 4 are aligned with the two transparent grooves 92 respectively, the phosphating solution remaining on the surface of the frame 4 and the filter screen 5 will flow into the storage box 11 together with the impurities, resulting in a waste of the phosphating solution. Therefore, after the phosphating solution and the impurities flow into the storage box 11 together, the impurities are intercepted by the filter screen 12, and the phosphating solution falls to the lower part of the storage box 11 through the filter screen 12, and then flows back to the box body 1 through the transparent grooves three 94 and the transparent grooves four 95. When in use, the phosphating solution that flows into the storage box 11 together with the impurities can flow back to the box body 1 through the transparent grooves three 94 and the transparent grooves four 95 to avoid waste.

During regular maintenance, valve 202 is opened, and the phosphating liquid in box 1 flows out from pipe 201 to the external drain pipe.

Example 2

Based on the first embodiment, as shown in FIG. 3 , the frame 4 is in an inverted V shape.

The upper surface of the frame 4 is set to be a smooth surface to reduce the amount of impurities remaining.

When the frame 4 and the filter screen 5 move upward in the phosphating solution, the surface of the inverted V-shaped frame 4 guides the phosphating solution obliquely forward and backward, so that the phosphating solution impacts the impurities remaining on the filter screen 5 forward or backward, and then the impurities originally remaining on the filter screen 5 are accumulated on the front and rear sides of the frame 4. When the front and rear sides of the frame 4 are aligned with the two transparent grooves 92 respectively, the impurities accumulated on the front and rear sides of the frame 4 can quickly fall into the storage box 11 for collection, which is beneficial to improve efficiency. When in use, during the rising process of the frame 4 and the filter screen 5, especially when the frame 4 and the filter screen 5 are lifted from the surface of the phosphating solution, the impurities accumulated on the front and rear sides of the frame 4 can be quickly lifted. In the process of floating out and separating from the phosphating liquid, the phosphating liquid is guided by the surface of the inverted V-shaped frame 4, so that the phosphating liquid can pre-impact and carry the impurities remaining on the filter screen 5 to the front and rear sides of the frame 4, so that the impurities can quickly fall into the storage box 11 for collection, which is beneficial to improve efficiency; and the entire impurity collection process is completely integrated into the process of lifting the frame 4 from the phosphating liquid. No additional electric drive mechanism is required for the collection of impurities. The process of replacing a new steel plate to be phosphated is also a process of removing impurities. There is no need to consume additional impurity removal processing time. The overall production and impurity removal process is coherent and efficient.

Example 3

Based on Example 2, as shown in FIG3 and FIG6,

It also includes a flushing component; the flushing component is connected to the box body 1; the flushing component includes a box body 2 301, a pipeline 2 302, an anti-corrosion pump 303 and a pipeline 304; two box bodies 2 301 are bolted to the box body 1, and the box body 2 301 is made of anti-corrosion material; each box body 2 301 is provided with a transparent groove 5 96, and the solution in the box body 2 301 flows to the front side and the rear side of the upper surface of the frame 4 through the transparent groove 5 96; all the box bodies 2 301 are connected to the pipeline 2 302; the anti-corrosion pump 303 is arranged on the side of the box body 1; the output end of the anti-corrosion pump 303 is connected to the pipeline 2 302; the box body 1 is connected to the pipeline 3 304; the input end of the anti-corrosion pump 303 is connected to the pipeline 3 304.

The input end of pipeline three 304 is located below filter screen one 5.

It also includes a guide plate 305; a plurality of guide plates 305 arranged in an inclined manner are welded to the inner side of the frame 4.

The outer surface of the box body 1 is coated with an anti-corrosion layer to prevent the box body 1 from corrosion.

When impurities slide down the frame 4 and the upper surface of the filter screen 5 into the storage box 11, some impurities will always remain on the front and rear sides of the frame 4. Therefore, after the vibration is completed, the anti-corrosion pump 303 is started, so that the phosphating liquid in the box body 1 flows into the box body 2 301 through the pipe 3 304, the anti-corrosion pump 303 and the pipe 2 302 in turn, and then flows out from the transparent groove 5 96 to the front and rear sides of the frame 4, and the impurities remaining on the front and rear sides of the frame 4 are flushed into the storage box 11 for collection, thereby avoiding the problem that the impurities remaining on the front and rear sides of the frame 4 are difficult to slide down. In addition, the input end of the pipe 3 304 is always located below the filter screen 15, so that the filter screen 15 can also prevent impurities from flowing into the pipe 3 304 and clogging it.

During the up and down movement of the frame 4, the frame 4 will also drive the guide plate 305 to move up and down, so that the guide plate 305 diagonally guides the phosphating solution, thereby stirring the phosphating solution, so that various components in the phosphating solution are evenly distributed, which is beneficial to improving the uniformity of phosphating of the steel plate.
