Description

Technical Field

[0001] This utility model relates to the field of stripping fluid regeneration technology, and in particular to a stripping fluid regeneration filter tank. Background Technology

[0002] Stripping fluid regeneration involves collecting used stripping fluid and then reconfiguring it to improve the utilization rate of the stripping fluid and related raw materials. This method reduces both production costs and environmental pollution. During stripping fluid regeneration, it is necessary to filter out solids. Common filtration methods include using multiple membranes with different filtration capacities or using filter tanks. However, when using filter tanks, the stripping waste fluid often accumulates in a certain area of ​​the tank. Over time, a large amount of solid impurities will deposit on the inner wall of the filter membrane, reducing its filtration capacity. Therefore, frequent backwashing is required to remove these impurities. However, cleaning the filter membrane interrupts the filtration of the waste fluid, thus affecting the regeneration of the stripping waste fluid. Utility Model Content

[0003] This invention provides a stripping fluid regeneration filter tank to overcome the shortcomings of the prior art and solve the problem that the stripping waste liquid accumulates in a single area during filtration, thus affecting the filtration capacity. It has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A stripping fluid regeneration filter tank includes a tank body, which is vertically oriented. Canister heads are bolted to both ends of the tank body, and pipes are connected to the canister heads. An inner ring is welded to the upper part of the tank body, and a mounting ring is screwed to the lower side of the inner ring. A filter cover is mounted on the mounting ring, and a convex shell is bolted to the lower end of the filter cover. Multiple holes are formed in the convex shell and the filter cover. Filter membranes are respectively provided on the inner wall of the filter cover and the outer wall of the convex shell. An annular cavity exists between the outer periphery of the convex shell and the inner periphery of the lower end of the filter cover. During filtration, the stripping fluid discharged downwards... The waste liquid first contacts the end face of the convex shell, causing it to flow downwards along the outer wall of the shell. Then, it passes through the filter cover and the filter membrane on the convex shell to filter solid impurities. As filtration proceeds, solid impurities gradually accumulate in the annular cavity, making it easier to control them within a single area. As filtration continues, these accumulated solid impurities act as a filter membrane, performing the first filtration of the waste liquid. The waste liquid is then filtered again through the filter membrane, thus improving the filtration effect through two filtration processes.

[0006] Furthermore, the longitudinal section of the convex shell is concave. Of course, the upper end of the convex shell can also be processed into a conical structure to facilitate the diversion of the stripping waste liquid.

[0007] Furthermore, an upper ring is provided at the upper end of the inner ring. The upper ring is located inside the can, and the mounting ring is installed on the upper ring by screws. This method facilitates the installation of the mounting ring.

[0008] Furthermore, to prevent the stripping waste liquid from accumulating or remaining on the upper surface of the upper ring, the inner circumference of the upper ring is designed with a conical structure, and the lower end of the inner circumference of the upper ring is the smaller end.

[0009] Furthermore, in order to further distribute the stripping waste liquid more evenly, thereby increasing the actual process area of ​​the filter membrane and improving the filtration effect of the filter membrane, an inner tank is bolted to the upper end of the convex shell. A conical shell is welded to the upper end of the inner tank. The upper end of the conical shell is the small end, and an upper extension column is provided at the upper end of the conical shell. The inner tank and the conical shell are located inside the filter cover, and the upper extension column extends out of the filter cover and is located directly below the pipeline.

[0010] Furthermore, in order to filter the stripping waste liquid multiple times and remove some of the larger solid impurities, multiple ring plates are welded on the outer periphery of the conical shell, with the width of the ring plates increasing sequentially from top to bottom.

[0011] To facilitate the filtration of the stripped waste liquid, multiple drainage holes are provided on the ring plate.

[0012] Furthermore, in order to improve the filtration effect, multiple partition rings are welded to the outer periphery of the inner tank. The longitudinal section of the partition rings is L-shaped. When the stripping waste liquid flows down the inner wall of the inner tank, solid impurities can be filtered through the partition rings.

[0013] Furthermore, in order to facilitate the filtration of the stripping waste liquid, multiple leakage holes are provided on the spacer ring, and the diameter of the leakage holes is smaller than that of the drainage holes.

[0014] The advantages of the above technical solution are:

[0015] This invention facilitates the filtration of stripped waste liquid and improves the filtration effect. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0019] Figure 3 A three-dimensional structural diagram of the inner tank is shown.

[0020] Figure 4 A three-dimensional structural diagram of the filter cover is shown. Detailed Implementation

[0021] like Figures 1-4 As shown, a stripping fluid regeneration filter tank includes a tank body 1, which is vertically oriented. Tank heads 10 are bolted to both ends of the tank body 1, and pipes 11 are connected to the tank heads 10.

[0022] An inner ring 12 is welded to the upper part of the inner body 1. An mounting ring 2 is installed on the lower side of the inner ring 12 by screws. An upper ring 22 is provided at the upper end of the inner ring 12. The upper ring 22 is located inside the can 10. The mounting ring 2 is installed on the upper ring 22 by screws. The inner circumference of the upper ring 22 has a conical structure, and the lower end of the inner circumference of the upper ring 22 is the smaller end. A filter cover 20 is provided on the mounting ring 2. A convex shell 21 is installed inside the lower end of the filter cover 20 by bolts. The longitudinal section of the convex shell 21 has a concave structure. Multiple holes are opened on the convex shell 21 and the filter cover 20. Filter membranes are respectively provided on the inner wall of the filter cover 20 and the outer wall of the convex shell 21. An annular cavity exists between the outer circumference of the convex shell 21 and the inner circumference of the lower end of the filter cover 20.

[0023] An inner tank 32 is bolted to the upper end of the convex shell 21. A conical shell 30 is welded to the upper end of the inner tank 32, with the upper end of the conical shell 30 being the smaller end. An upper extension column 3 is provided at the upper end of the conical shell 30. The inner tank 32 and the conical shell 30 are located inside the filter cover 20. The upper extension column 3 extends out of the filter cover 20 and is located directly below the pipe 11. Multiple ring plates 31 are welded to the outer periphery of the conical shell 30. The width of the ring plates 31 increases sequentially from top to bottom. Multiple drain holes are provided on the ring plates 31. Multiple spacer rings 33 are welded to the outer periphery of the inner tank 32. The longitudinal section of the spacer rings 33 is L-shaped, and multiple leakage holes are provided on the spacer rings 33.

[0024] In this embodiment, during operation, the stripping waste liquid is injected into the tank 1 through pipe 11. When the stripping waste liquid enters the tank 1, it flows downward on the conical shell 30. During the flow, the annular plate 31 filters out some of the larger solid impurities. To allow the stripping waste liquid to flow downward, the width of the annular plate 31 increases sequentially from top to bottom. This prevents solid impurities from being washed away. Simultaneously, as the stripping waste liquid flows outward on the annular plate 31, some of it is filtered through the filter membrane on the filter cover 20. A portion of the stripping waste liquid flows downward along the inner tank 32 and is filtered multiple times by the partition ring 33. During this process, the filter membrane filters out any splashed stripping waste liquid. To prevent solid impurities filtered out by the partition ring 33 from moving outward, the partition ring 33 is designed with an L-shaped structure. Then, some of the stripping waste liquid will flow into the annular cavity and be filtered through the filter membrane inside the annular cavity. As filtration proceeds, the impurities accumulated in the annular cavity will then act as filters, thereby improving the filtration effect of the stripping waste liquid.

Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
