[0002] High-viscosity melt material filters play a key role in removing impurities, protecting equipment, and improving product quality and efficiency. They are widely used in industries such as plastics, chemical fibers, rubber, and food.

[0003] Currently, there are some problems in filtering molten materials: 1. Due to the high viscosity and high flow resistance of molten materials, existing bag filters are side-in and bottom-out, which increases the resistance due to two bends in the material flow process. To ensure the flow rate, the pump pressure must be increased, which often leads to leaks at the pipeline connection or blockages at the bends; 2. The filter screen cannot be easily replaced. The inconvenience of filter screen replacement increases downtime and further reduces production capacity. Therefore, we need to propose a filter for high-viscosity molten materials with an easy-to-replace filter screen. Utility Model Content

[0004] The purpose of this utility model is to provide a high-viscosity melt material filter that is easy to replace the filter screen. In order to reduce resistance, the melt material is discharged vertically. Vertical discharge can utilize gravity, reduce pumping pressure, reduce energy consumption, and reduce retention and blockage, improve flow efficiency, reduce the rate of material retention and blockage, reduce maintenance frequency and cost, and extend the service life of the equipment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[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 1-7 This utility model provides a technical solution:

[0028] A filter for high-viscosity melt materials with easy-to-replace filter screen includes a first pipe 1 and a second pipe 2 arranged vertically. A first insulated ball valve 3 is fixedly installed at the bottom of the first pipe 1, and a second insulated ball valve 4 is fixedly installed at the top of the second pipe 2. A connecting pipe 12 is fixedly installed at the top of the second insulated ball valve 4, and an installation pipe 19 is fixedly connected to the top of the connecting pipe 12. A filter screen 8 for filtering high-viscosity melt materials is provided inside the installation pipe 19.

[0029] Mounting plates 5 are fixedly connected to both the first pipe 1 and the second pipe 2. Mounting rods 6 are fixedly connected to the mounting plates 5. Rotating brackets 9 are movably mounted on the fixing rods 6. Short pipes 10 are fixedly mounted on the rotating brackets 9. Short pipes 10 are located between the first insulated ball valve 3 and the mounting pipe 19. Short pipes 10 are equipped with quick-release mechanisms. Short pipes 10 are fixedly mounted on the first insulated ball valve 3 and the mounting pipe 19 through quick-release mechanisms.

[0030] It should be noted that the first insulated ball valve 3 and the second insulated ball valve 4 can be used to seal the first pipe 1 and the second pipe 2, thereby preventing the leakage of highly viscous molten materials. This facilitates the replacement of the filter screen 8 after the short pipe 10 is disassembled. In addition, the mounting plate 5, the fixing rod 6 and the rotating bracket 9 can be used to adjust the position of the short pipe 10, so as to replace the filter screen 8.

[0031] In an optional embodiment: the quick-release mechanism includes a fixed base 15, a plug rod 16, a push spring 17, and a push ring 18. The upper and lower ends of the short pipe 10 are fixedly connected to the mounting plate 11. The fixed base 15 is fixedly installed on the mounting plate 11. The plug rod 16 is movably inserted into the fixed base 15. The push spring 17 is sleeved on the plug rod 16. The push ring 18 is fixedly connected to the top of the plug rod 16. One end of the push spring 17 is pressed against the inner top of the fixed base 15, and the lower end of the push spring 17 is pressed against the top of the push ring 18. The push spring 17 is inserted into the flange of the first heat-insulating ball valve 3 and the mounting pipe 19.

[0032] It should be noted that the combination of the fixed base 15, the plug rod 16, the push spring 17 and the push ring 18 facilitates the disassembly and installation of the short pipe 10, improves the efficiency of disassembly and installation of the short pipe 10, and makes it easier to replace the filter screen 8.

[0033] In an optional embodiment: a positioning rod 20 is fixedly connected to the top of the fixed base 15, and a guide groove 21 and a support groove 22 are provided in the insertion rod 16. The guide groove 21 and the support groove 22 are connected, and the positioning rod 20 is inserted into the guide groove 21.

[0034] It should be noted that the positioning rod 20, guide groove 21 and support groove 22 cooperate to position the plug rod 16, thereby blocking the plug rod 16 and preventing it from resetting, and preventing the short pipe 10 from being moved away from the first heat-insulating ball valve 3 and the installation pipe 19 or from being moved between the first heat-insulating ball valve 3 and the installation pipe 19.

[0035] In an optional embodiment, a material collection ring 13 for collecting material is fixedly connected to the inner wall of the short pipe 10.

[0036] It should be noted that the collection ring 13 is designed to collect high-viscosity melt materials, which facilitates the collection of high-viscosity melt materials in the connecting pipe 12 and their subsequent filtration into the filter screen 8.

[0037] In an optional embodiment: a fixing ring 14 is fixedly installed on the inner wall of the mounting tube 19, and a support ring 27 is fixedly connected to the inner wall of the fixing ring 14. A support metal mesh barrel 7 for supporting the filter screen 8 is inserted into the support ring 27. The filter screen 8 is disposed in the support metal mesh barrel 7. A lead screw 23 is movably installed in the fixing ring 14. A clamping ring 25 is threaded on the lead screw 23. The clamping ring 25 is pressed against the filter screen 8 and the support metal mesh barrel 7.

[0038] It should be noted that the metal mesh support 7 provides support for the filter screen 8. The screw 23, in conjunction with the clamping ring 25, clamps and secures the filter screen 8 to the metal mesh support 7, thus ensuring the stability of the filter screen 8 and the metal mesh support 7 after installation.

[0039] In an optional embodiment: a guide rod 24 is fixedly installed on the inner wall of the push spring 17, and a clamping ring 25 is slidably installed on the guide rod 24, with the surface of the clamping ring 25 in contact with the inner wall of the fixed ring 14.

[0040] It should be noted that the guide rod 24 serves to guide and position the clamping ring 25, enabling the clamping ring 25 to move vertically.

[0041] In an optional embodiment: a sealing gasket 26 is provided on the mounting plate 11, the sealing gasket 26 at the top of the mounting plate 11 at the upper end of the short pipe 10 contacts the flange at the lower end of the first insulated ball valve 3, and the sealing gasket 26 at the bottom of the mounting plate 11 at the lower end of the short pipe 10 contacts the top of the mounting pipe 19.

[0042] It should be noted that the sealing gasket 26 achieves a sealing effect between the mounting plate 11 at the upper end of the short pipe 10 and the lower end of the first insulated ball valve 3, as well as between the mounting plate 11 at the lower end of the short pipe 10 and the top of the mounting pipe 19, preventing leakage of high-viscosity molten materials.

[0043] In an optional embodiment, a threaded sleeve 28 is threaded onto the lower end of the plug rod 16, and the threaded sleeve 28 abuts against the flange at the lower end of the first insulated ball valve 3 and the mounting pipe 19.

[0044] It should be noted that by setting the threaded sleeve 28, the installation effect of the short pipe 10 on the first insulated ball valve 3 and the installation pipe 19 can be improved.

[0045] In practical use, the high-viscosity melt material falls into the installation pipe 19 after passing through the first pipe 1, the first insulated ball valve 3 and the short pipe 10. After being filtered by the filter screen 8 in the installation pipe 19, the high-viscosity melt material falls onto the inner wall of the installation pipe 19 and then falls into the connecting pipe 12. The high-viscosity melt material is discharged along the connecting pipe 12, the second insulated ball valve 4 and the second pipe 2. By passing through the vertical first pipe 1, the second pipe 2, the first insulated ball valve 3, the short pipe 10, the installation pipe 19, the connecting pipe 12, the second insulated ball valve 4 and the second pipe 2, gravity can be used to reduce pumping pressure and energy consumption. Vertical discharge can also reduce retention and blockage, improve flow efficiency, reduce the rate of material retention and blockage, reduce maintenance frequency and cost, and extend the service life of the equipment.

[0046] When the filter screen 8 needs to be cleaned, the threaded sleeve 28 is loosened and removed. Then, the insertion rod 16 is dragged so that the positioning rod 20 moves in the guide groove 21. When the bottom of the insertion rod 16 moves out from the flange of the first insulated ball valve 3 and the top of the mounting pipe 19, the positioning rod 20 contacts the bottom of the guide groove 21. By rotating the insertion rod 16, the positioning rod 20 is positioned in the support groove 22. By loosening the insertion rod 16, the insertion rod 16 is locked in the fixed seat 15 by the positioning rod 20 and the support groove 22. By rotating the rotating bracket 9, the short pipe 10 is moved away from the first insulated ball valve 3 and the mounting pipe 19 when the rotating bracket 9 rotates on the fixed rod 6.

[0047] By turning the screw 23, the screw 23 drives the clamping ring 25 to move away from the filter screen 8. After the clamping ring 25 moves away from the filter screen 8, the filter screen 8 is replaced from the supporting metal mesh barrel 7. After the new filter screen 8 is replaced, the edge of the filter screen 8 is set at the top of the supporting metal mesh barrel 7. By turning the screw 23, the screw 23 drives the clamping ring 25 to move downward, so that the clamping ring 25 presses against the filter screen 8 and the supporting metal mesh barrel 7, thereby fixing the filter screen 8 and improving the stability of the filter screen 8 after installation.

[0048] After replacing the filter screen 8, rotating the rotating bracket 9 causes the short connecting pipe 10 to move between the first insulated ball valve 3 and the mounting pipe 19. Rotating the plug rod 16 moves the positioning rod 20 from the support groove 22 to the guide groove 21. Then, releasing the push spring 17 allows the push spring 17 to push the plug rod 16 through the push ring 18, enabling the plug rod 16 to be inserted into the flange of the first insulated ball valve 3 and the top of the mounting pipe 19, thus positioning the short connecting pipe 10. By threading the threaded sleeve 28 onto the plug rod 16, the short connecting pipe 10 can be fixedly installed on the first insulated ball valve 3 and the mounting pipe 19. This allows for quick replacement of the filter screen 8, improving the efficiency of filter screen replacement, reducing downtime, and ultimately increasing production efficiency.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
