Description

Technical Field

[0001] This utility model relates to the field of antistatic production, and specifically to an antistatic agent filtration device. Background Technology

[0002] Antistatic agents are chemical substances that effectively reduce or eliminate the accumulation of static electricity on the surface of objects, and are widely used in many industries such as electronics, textiles, and plastics. During their production, due to the presence of impurities in raw materials and reaction byproducts, the filtration process is crucial to ensure the purity and performance stability of the antistatic agent. However, existing antistatic agent filtration devices generally suffer from low filter replacement efficiency. Conventional filtration devices often use complex fixing methods for the filter screen and the main structure, requiring the disassembly of numerous parts for replacement, making the operation cumbersome, time-consuming, and impacting production efficiency. Utility Model Content

The filter screen two is located between the lower conduit and the upper conduit, and the upper end of the lower conduit is threadedly connected to the lower end of the upper conduit. The filter screen three is located between the upper conduit and the upper end cap, and the lower end of the upper end cap is threadedly connected to the upper end of the upper conduit. The lower conduit, the upper conduit, the upper end cap, the lower end cap, the filter screen one, the filter screen two, and the filter screen three constitute an inner filtration assembly. The inner filtration assembly is disposed inside the outer casing, and the inner filtration assembly has a flow channel inside. The upper end cap is threadedly connected to the inside of the upper tube, and the outer end of the upper tube is threadedly connected to the upper end of the outer casing. The mesh size of the filter screen one, the filter screen two, and the filter screen three is progressively reduced.

[0017] The following describes the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0018] Example 1

[0019] An antistatic agent filtration device includes: an outer casing 1, an upper tube 2, a lower conduit 3, an upper conduit 4, an upper end cap 6, a lower end cap 7, a first filter screen 8, a second filter screen 9, and a third filter screen 10. The first filter screen 8 is located between the lower conduit 3 and the lower end cap 7. The lower end cap 7 is threadedly connected to the lower end of the lower conduit 3. The second filter screen 9 is located between the lower conduit 3 and the upper conduit 4. The upper end of the lower conduit 3 is threadedly connected to the lower end of the upper conduit 4. The third filter screen 10 is located between the upper conduit 4 and the upper end cap 6. The upper end cap 6 is threaded to the upper end of the upper conduit 4. The lower conduit 3, upper conduit 4, upper end cap 6, lower end cap 7, filter screen 1 8, filter screen 2 9, and filter screen 3 10 constitute an inner filter assembly. The inner filter assembly is located inside the outer jacket 1. The inner filter assembly has a flow channel 11 inside. The upper end cap 6 is threaded to the inside of the upper tube 2. The outer end of the upper tube 2 is threaded to the upper end of the outer jacket 1. The mesh size of the filter screen 1 8, filter screen 2 9, and filter screen 3 10 is progressively reduced.

[0020] like Figures 1-4 As shown, the working principle of this embodiment is as follows: the antistatic agent enters the flow channel 11 inside the inner filter assembly from the upper pipe 2, and passes sequentially through filter screen 10, filter screen 9, and filter screen 8. Since the mesh size of filter screen 8, filter screen 9, and filter screen 10 decreases step by step, the larger mesh size of filter screen 10 first intercepts larger particulate impurities. As the antistatic agent flows downward, the mesh size of filter screen 9 and filter screen 8, which decreases step by step, gradually filters smaller particulate impurities, achieving multi-stage fine filtration. Finally, the pure antistatic agent flows out from the lower conduit 3.

[0021] The filters 8, 9, and 10 in this embodiment are easy to disassemble and replace. Filter 8 is placed in an annular cavity 1 formed between the lower guide tube 3 and the lower end cap 7. The lower end cap 7 is threaded to the lower end of the lower guide tube 3. When filter 8 needs to be replaced, simply unscrew the lower end cap 7 to remove filter 8 directly from the annular cavity 1. Filter 29 is located in an annular cavity 2 between the lower guide tube 3 and the upper guide tube 4. The lower guide tube 3 and the upper guide tube 4 are threaded together. When replacing filter 29, simply unscrew the threaded connection to easily remove filter 29. Filter 310 is installed in an annular cavity 3 between the upper guide tube 4 and the upper end cap 6. The upper end cap 6 is also threaded to the lower end of the upper guide tube 4. Unscrewing the upper end cap 6 allows for quick disassembly of filter 310.

[0022] As a further preferred embodiment, the lower end cap 7 and the lower end of the lower conduit 3 form an annular cavity 11, the filter screen 8 is disposed inside the annular cavity 11, and the threaded connection between the lower end cap 7 and the lower conduit 3 is located outside the annular cavity 11.

[0023] The lower end cap 7 and the lower end of the lower guide tube 3 form an annular cavity. The filter screen 8 is housed within this annular cavity, with the threaded connection between the lower end cap 7 and the lower guide tube 3 located outside the annular cavity. The principle is to utilize the annular cavity to provide installation space for the filter screen 8. When the filter screen 8 needs replacement, simply unscrew the lower end cap 7 to remove it directly, without disassembling other components. This design is highly effective, greatly simplifying the filter screen 8 replacement process, improving replacement efficiency, reducing equipment downtime, and ensuring production continuity.

[0024] As a further preferred embodiment, the upper end of the lower conduit 3 and the lower end of the upper conduit 4 form an annular cavity 2 12, the filter screen 2 9 is disposed in the annular cavity 2 12, and the threaded connection position between the lower conduit 3 and the upper conduit 4 is located outside the annular cavity 2 12.

[0025] The upper end of the lower conduit 3 and the lower end of the upper conduit 4 form an annular cavity II. Filter screen II 9 is disposed within the annular cavity II, and the threaded connection between the lower conduit 3 and the upper conduit 4 is located outside the annular cavity II. The principle is similar to the above; the annular cavity II is used to install filter screen II 9. When filter screen II 9 becomes clogged or reaches the end of its service life and needs replacement, the threaded connection between the lower conduit 3 and the upper conduit 4 can be unscrewed to remove filter screen II 9 for replacement. This design avoids large-scale disassembly of the entire filtration device when replacing filter screen II 9, making the replacement operation simple and quick, effectively improving maintenance efficiency and reducing labor intensity.

[0026] As a further preferred embodiment, the lower end of the upper cover 6 and the upper end of the upper conduit 4 form an annular cavity 3 13, the filter screen 2 9 is disposed inside the annular cavity 3 13, and the threaded connection position between the upper cover 6 and the upper conduit 4 is located outside the annular cavity 3 13.

[0027] The lower end of the upper cap 6 and the upper end of the upper guide tube 4 form an annular cavity three. The filter screen three 10 is disposed inside the annular cavity three, and the threaded connection between the upper cap 6 and the upper guide tube 4 is located outside the annular cavity three. Similarly, the annular cavity three provides an independent installation space for the filter screen three 10. When replacing the filter screen three 10, simply unscrew the upper cap 6 to easily replace it. This structural design ensures that the replacement of each filter stage does not interfere with each other, allowing for flexible replacement based on the actual usage of the filter, improving the targeting and efficiency of filter replacement, and further optimizing the maintainability of the filtration device.

[0028] As a further preferred embodiment, a sealing ring 5 is provided at the upper end of the outer sleeve 1 and at the contact surface with the lower end of the upper tube 2. The elastic deformation of the sealing ring 5 fills the gap between the outer sleeve 1 and the upper tube 2, forming a sealed structure to prevent the antistatic agent from leaking from the connection point during the filtration process.

[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
