Description

Technical Field

[0001] This utility model relates to the field of filtration equipment, and more specifically, to a fully automatic phosphating filtration device. Background Technology

[0002] In the pretreatment process of metal surface coating, phosphating is a crucial step, significantly enhancing the adhesion and corrosion resistance of the coating. Especially in the automotive industry, phosphating films are widely used as the base layer for electrophoretic coatings. However, phosphating inevitably produces phosphating slag. Excessive phosphating slag, if not removed from the bath in a timely manner, will not only contaminate the phosphating solution, drastically shorten its lifespan, and increase production costs, but will also adhere to the workpiece surface, severely affecting the quality of the phosphating film and ultimately reducing the overall coating quality of the vehicle. For spraying systems, excessive phosphating slag can easily lead to nozzle and pipeline blockage, reducing the heat transfer efficiency of the heat exchange system, and even causing the entire production line to malfunction. Therefore, effectively controlling the phosphating slag content in the bath is of paramount importance, which has spurred the development of various phosphating slag removal systems (devices).

[0003] Existing fully automated phosphating filtration equipment faces significant challenges in handling residues on the filter cloth surface. Taking common automatic paper-feeding belt filters as an example, while they can achieve some degree of automatic forward movement and residue removal of the filter paper, overflow is still likely when the filter paper is full of residue, especially with large volumes of phosphating solution. Furthermore, there is a lack of effective automated methods for cleaning residues from the filter cloth surface. Some filters are not designed with timely and efficient cleaning of filter cloth surface residues in mind. As filtration continues, residues accumulate on the filter cloth surface, affecting not only filtration efficiency but also filtration accuracy, increasing impurity content in the phosphating solution, and ultimately impacting phosphating quality. Additionally, current methods for cleaning filter cloth surface residues are inconvenient due to operational gaps. Methods using high-pressure gas or liquid rinsing are not only energy-intensive but may also leave residues inside the equipment, causing secondary pollution and resulting in poor cleaning effectiveness. These methods fail to meet the actual production requirements for efficient and convenient cleaning of filter cloth surface residues.

[0004] Therefore, improvements are needed to the existing fully automated phosphating filtration equipment to overcome the aforementioned shortcomings. Utility Model Content

[0005] The main objective of this application is to provide a fully automatic phosphating filtration device with sufficient operating space to clean residue from the surface of the filter cloth.

[0006] To achieve the above objectives, in a first aspect, this application provides a fully automatic phosphating filtration device, including a fixedly disposed inlet tank, an inlet assembly connected to the inlet tank, a sliding frame slidably disposed relative to the inlet tank along a plumb line, and a drive assembly for driving the sliding frame to slide. A liquid collection chamber is fixedly disposed on the sliding frame facing the inlet tank. An unwinding roller and a winding roller are rotatably disposed at both ends of the sliding frame, and the unwinding roller and the winding roller are respectively controlled to rotate by a control mechanism. A portion of the filter layer is wound on the unwinding roller and the winding roller, and a drain pipe is connected to the liquid collection chamber.

[0007] Optionally, the filter layer is a non-woven filter cloth or filter paper.

[0008] Optionally, guide plates are rotatably provided at both ends of the sliding frame, and an adjustment structure is provided between the guide plates and the sliding frame.

[0009] Optionally, the adjustment structure includes a locking gear plate fixedly mounted on the sliding frame and a paddle fixedly mounted on the same axis as the guide plate, the paddle cooperating with the locking gear plate.

[0023] In addition, the term "multiple" should mean two or more.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-3 As shown, a fully automatic phosphating filtration device includes a fixedly installed inlet tank 1, an inlet assembly 2 connected to the inlet tank 1, a sliding frame 3 slidably arranged relative to the inlet tank 1 along a plumb line, and a driving assembly for driving the sliding frame 3 to slide. A liquid collection chamber 4 is fixedly installed on the sliding frame 3 facing the inlet tank 1. An unwinding roller 5 and a winding roller 6 are rotatably arranged at both ends of the sliding frame 3, respectively. The unwinding roller 5 and the winding roller 6 are controlled to rotate by a control mechanism 14, which is a motor. A portion of the filter layer is wound on the unwinding roller 5 and the winding roller 6. The liquid collection chamber 4 is connected to a drain pipe 13.

[0026] The filter layer is a non-woven filter cloth or filter paper. Taking the non-woven filter cloth as an example, part of it is wound onto the unwinding roller 5 and the other part is wound onto the take-up roller 6, which covers the opening of the liquid collection chamber 4. When the phosphating liquid to be filtered falls from the inlet tank 1 into the liquid collection chamber 4, it is filtered for residue through the filter layer. When cleaning is required, the drive mechanism 11 controls the inlet tank 1 to move away from the sliding frame 3, thereby increasing the gap between the two, so that there is enough space for operation, and no additional automatic cleaning structure is required. It is not only simple in structure but also easy to clean.

[0027] To facilitate adjustment of the filter layer's tightness and guide it during residue removal, guide plates 7 are rotatably mounted at both ends of the sliding frame 3. An adjustment structure is provided between the guide plates 7 and the sliding frame 3. The adjustment structure includes a locking gear disc 10 fixedly mounted on the sliding frame 3 and a paddle 9 fixedly mounted on the same axis as the guide plates 7. The paddle 9 cooperates with the locking gear disc 10. By rotating the angle of the paddle 9, different angles of cooperation with the locking gear disc 10 can be achieved, thereby adjusting the angle of the guide plate 7.

[0028] To reduce sharp edges and prevent damage to the filter layer, a transition roller 8 is rotatably provided between the guide plate 7 and the sliding frame 3, and the guide plate 7 is connected to the sliding frame 3 through the transition roller 8.

[0029] In order to facilitate filtration and provide some support for the filter layer, a grid plate 12 is fixedly installed at the inlet of the liquid collection chamber 4.

[0030] To improve the filtration effect, a filter screen is installed inside the liquid inlet tank 1. By setting the filter screen, large-sized residues can be filtered first, reducing the pressure during subsequent filtration and also reducing the difficulty of cleaning its surface.

[0031] In this embodiment, preferably, the driving mechanism 11 is a driving cylinder or hydraulic cylinder disposed at the bottom of the sliding frame 3.

[0032] In addition, to ensure guiding accuracy, a guiding mechanism is provided between the liquid inlet tank 1 and the sliding frame 3. The guiding mechanism includes a guide sleeve 16 fixedly disposed on the liquid inlet tank 1 and a guide post 15 fixedly disposed on the sliding frame 3 and cooperating with the guide sleeve 16.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
