Description

Technical Field

[0001] This utility model relates to the technical field of ink production equipment, specifically a filter device that is easy to disassemble. Background Technology

[0002] Filtration during ink production aims to remove pigment agglomerates, undispersed particles, mechanical impurities, and foreign matter introduced during production. This ensures the purity and uniformity of the ink, prevents clogging of pen tips, printheads, or printing screens, and guarantees the ink's smoothness, color stability, and printing / writing quality in different application scenarios. Ultimately, it improves the quality and applicability of the ink, reduces product defect rates caused by impurities, and extends the lifespan of the equipment used.

[0003] A search revealed Chinese patent number CN202121752187.2, which relates to a filtration device for writing ink production. The device includes two sets of filter housings, an inlet pipe, an inlet control valve, an inlet branch pipe, an inlet port, an outlet pipe, an outlet control valve, an outlet manifold, an outlet, and a filtration mechanism. The filter housings contain a filtration chamber. Both sets of filter housings are connected to an inlet pipe, which is connected to an inlet control valve. The two output ends of the inlet branch pipe are connected to the two inlet control valves respectively. The inlet port is connected to the inlet branch pipe. The outlet pipe is connected to the filter housing, and an outlet control valve is connected to the outlet pipe.

[0004] The above-mentioned technical solutions and traditional filtration equipment still have shortcomings. For example, they usually adopt an integrated structure or a complex connection method. The housing of some filtration devices is tightly fixed by multiple bolts. When it is necessary to clean the filter components or replace the filter element, the operator needs to spend a lot of time and effort to disassemble and assemble. For example, there is no buffer function for the filter element. The direct impact of ink on the filter element can easily reduce the service life of the filter element. Therefore, we need to propose a filtration device that is easy to disassemble. Utility Model Content

[0005] The purpose of this utility model is to provide a filter device that is easy to disassemble, shortens the time for cleaning or replacing the filter element, and significantly improves maintenance efficiency; at the same time, it simplifies the operation process and reduces labor intensity, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A detachable filter device, comprising:

[0008] Filter chamber and top cover;

[0009] The top cover is installed on top of the filter chamber, and the top of the top cover is provided with an inlet for ink input, and the bottom of the filter chamber is provided with an outlet for ink output. The filter chamber is equipped with a filter element.

[0010] The bottom of the top cover is provided with a threaded ring, and the inner wall of the top opening of the filter chamber is provided with a threaded section. The threaded section and the threaded ring are compatible. The bottom of the top cover is connected to a top plate through a bracket. The bottom of the top plate is provided with an upper rim. The inner bottom of the filter chamber is provided with a lower rim around the outlet. The sealing rings at the upper and lower ends of the filter element are respectively sealed and inserted into the interior of the upper rim and the lower rim.

[0011] Preferably, a rubber convex ring is provided around the bottom of the threaded ring, and an annular groove is provided on the top end face of the filter chamber. When the top cover is installed on the top of the filter chamber, the convex ring is inserted into the groove to improve the sealing performance.

[0012] Preferably, it also includes a flow guiding structure for reducing the impact force of ink entering the filter chamber, the flow guiding structure including a flow guiding block disposed on the top of the top plate.

[0013] Preferably, the guide block has a conical design, and the outer wall of the guide block has multiple sets of guide grooves distributed radially.

[0014] Preferably, a connecting rod is arranged around the bottom of the guide block, the connecting rod is slidably inserted into the top plate, and a limit block is provided at the lower end of the connecting rod.

[0015] Preferably, two sets of rubber washers are slidably sleeved on the connecting rod between the top plate and the guide block, and a compression spring is slidably sleeved on the connecting rod between the two sets of washers. The compression spring and the washers work together to buffer the impact force of the ink.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The connection method using threaded rings and threaded segments allows for quick disassembly and installation by operators simply by rotating the top cover, compared to the traditional method of fixing with multiple bolts. This significantly reduces the time required for cleaning or replacing the filter element and greatly improves maintenance efficiency. At the same time, it simplifies the operation process and reduces labor intensity.

[0018] 2.

The double sealing design significantly improves the sealing performance of the device, avoids ink leakage, and ensures filtration effect and production safety.

[0019] 3. The conical guide block and the guide groove on its outer wall in the flow guiding structure can effectively disperse the impact force of the ink entering the filter chamber, so that the ink flows evenly and gently to the filter element, reducing the risk of filter element damage caused by excessive ink impact; at the same time, the stable water flow helps to improve filtration efficiency and effect, ensure stable ink quality, and extend the service life of the filter element.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-3 This utility model provides a technical solution:

[0028] A detachable filter device, comprising:

[0029] The filter chamber 1 and the top cover 2 are installed on top of the filter chamber 1. The top of the top cover 2 is provided with an inlet 3 for ink input, and the bottom of the filter chamber 1 is provided with an outlet 4 for ink output. The filter element 5 is installed inside the filter chamber 1. The bottom of the top cover 2 is provided with a threaded ring 10, and the inner wall of the top opening of the filter chamber 1 is provided with a threaded section 11, which is compatible with the threaded ring 10. The bottom of the top cover 2 is connected to a top plate 7 through a bracket 9. The bottom of the top plate 7 is provided with an upper rim 8. The inner bottom of the filter chamber 1 is provided with a lower rim 6 around the outlet 4. The sealing rings at the upper and lower ends of the filter element 5 are respectively sealed and inserted into the interior of the upper rim 8 and the lower rim 6.

[0030] In use, inlet 3 connects to the ink input pipe, and outlet 4 connects to the ink output pipe. The threaded ring 10 at the bottom of the top cover 2 engages with the threaded section 11 on the inner wall of the top opening of the filter chamber 1, forming a detachable connection. Compared with traditional bolt connections, operators only need to rotate the top cover 2 to complete the disassembly and assembly, significantly shortening the time for cleaning or replacing the filter element 5. The sealing rings at the upper and lower ends of the filter element 5 inside the filter chamber 1 are respectively sealed and inserted into the upper edge 8 at the bottom of the top plate 7 and the lower edge 6 around the outlet 4 at the bottom of the filter chamber 1, ensuring that ink can only flow out after being filtered by the filter element 5, preventing unfiltered ink from bypassing and ensuring the filtration effect.

[0031] Please see Figure 1-3 :

[0032] A rubber protrusion 12 is provided around the bottom of the threaded ring 10, and an annular groove 13 is provided on the top end face of the filter chamber 1. When the top cover 2 is installed on the top of the filter chamber 1, the protrusion 12 is inserted into the groove 13 to improve the sealing performance.

[0033] When in use, the rubber protrusion 12 at the bottom of the threaded ring 10 and the annular groove 13 at the top of the filter chamber 1 engage with each other when the top cover 2 is installed. The elastic deformation of the rubber fills the gap and forms a sealing barrier, effectively preventing ink from leaking from the connection between the top cover 2 and the filter chamber 1. This further enhances the sealing performance of the device and prevents ink leakage from affecting the production environment or causing waste of raw materials.

[0034] Please see Figure 2-5 :

[0035] It also includes a flow guiding structure to reduce the impact force of ink entering the filter chamber 1. The flow guiding structure includes a flow guiding block 14, which is disposed on the top of the top plate 7. The flow guiding block 14 has a conical design, and its outer wall has multiple sets of flow guiding grooves 15 radially distributed. The top of the flow guiding block 14 faces the inlet 3.

[0036] In use, the guide block 14 is conical with its top facing the inlet 3. After the ink enters from the inlet 3, it first impacts the conical guide block 14. The conical structure disperses the ink in all directions. The radially distributed guide grooves 15 on the outer wall of the guide block 14 further guide the ink to flow along a specific path, so that the ink flows evenly and smoothly to the filter element 5, reducing the impact force of the ink on the filter element 5, reducing the risk of damage to the filter element 5 due to impact, and helping to improve filtration efficiency and effect.

[0037] Please see Figure 4-5 :

[0038] A connecting rod 16 is arranged around the bottom of the flow guide block 14. The connecting rod 16 is slidably inserted into the top plate 7, and a limit block 17 is provided at the lower end of the connecting rod 16. Two sets of rubber washers 18 are slidably sleeved on the connecting rod 16 between the top plate 7 and the flow guide block 14. A compression spring 19 is slidably sleeved on the connecting rod 16 between the two sets of washers 18. The compression spring 19 and the washers 18 work together to buffer the impact force of the ink.

[0039] During use, the connecting rod 16 at the bottom of the guide block 14 is slidably inserted into the top plate 7. When ink impacts the guide block 14, the guide block 14 can produce a slight displacement along the direction of the connecting rod 16. The compression spring 19 is compressed by force, and the rubber gasket 18 also deforms. The elastic force of the spring and the buffering effect of the rubber gasket 18 convert the impact force of the ink into elastic potential energy and internal energy, and perform secondary buffering of the impact force, further protecting the filter element 5 and extending its service life. At the same time, it makes the ink flow more stable and ensures the stability of the filtration process.

[0040] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
