DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] like Figures 1 to 12As shown, the present invention provides a pipeline conveying device for silicone rubber processing, comprising an input component 1, an output component 2, a conveying component 3 and a filtering component 4, wherein the input component 1 comprises an input pipeline 11 and at least one filter screen 12, wherein one end of the input pipeline 11 is open and the other end is closed, and the peripheral wall of the other end of the input pipeline 11 is provided with at least one first window 11a, and the filter screen 12 is detachably arranged in the first window 11a; the output component 2 comprises a sleeve 21 and an output pipeline 22, wherein the sleeve 21 is sleeved on the other end of the input pipeline 11 and sleeved on the first window 11a, wherein the sleeve 21 is sealedly connected to the outer wall of the input pipeline 11, and the feed end of the output pipeline 22 is connected to the sleeve 21; the conveying component 3 is connected to the input pipeline 11, and is partially built in the input pipeline 11, and is used to push the material from one end of the input pipeline 11 to the other end; the filtering component 4 comprises a filter cartridge 41, wherein the filter cartridge 41 is built in the sleeve 21 and is arranged between the sleeve 21 and the filter screen 12, and the filtering accuracy of the filter cartridge 41 is greater than the filtering accuracy of the filter screen 12.

[0047] The working principle of the pipeline conveying device for silicone rubber processing is as follows: the premixed silicone rubber is heated, and the heated silicone rubber is passed into the input pipe 11. The conveying component 3 drives the fluid silicone rubber to move in the input pipe 11, and drives the silicone rubber to move from one end of the input pipe 11 to the other end; the silicone rubber is pushed through the filter screen 12 along the radial direction of the input pipe 11, and enters between the filter screen 12 and the filter cylinder 41; the silicone rubber is pushed through the filter cylinder 41 along the radial direction of the input pipe 11, and enters between the filter cylinder 41 and the sleeve 21; finally, the silicone rubber enters the output pipe 22 from the sleeve 21 under extrusion.

[0048] Since the filter screen 12 is arranged in the first window 11a, and the first window 11a is arranged on the peripheral wall of the input pipe 11, the filter screen 12 can extend along the circumference of the input pipe 11, and can also extend along the axial direction of the input pipe 11. The size of the formed filtering surface is not limited by the inner diameter of the input pipe 11, and is much larger than the size of the filtering structure arranged in the input pipe 11. Secondly, on the basis of setting the filter screen 12, the present application further sets a filter cartridge 41, and the filter cartridge 41 can filter the silicone rubber filtered by the filter screen 12 again, and the filtering accuracy of the filter cartridge 41 is The filtration accuracy is greater than that of the filter 12, so as to form a cascade filtration. While achieving the same filtration effect, it can reduce the impurities intercepted by the filter 12 with relatively small filtration accuracy, reduce the speed at which the filter 12 is blocked, reduce the interception of the silicone rubber by the filter 12, and reduce the loss of the conveying pressure by the filter 12; the filter cartridge 41 can achieve precise interception. At the same time, during the precise interception process, the intercepted material is located between the filter cartridge 41 and the outer wall of the input pipe 11, so as to avoid the intercepted material in the precise filtration being blocked in the input pipe 11 and affecting the flow of the silicone rubber.

[0049] After the silicone rubber enters the gap between the filter cartridge 41 and the input pipe 11, the silicone rubber passes through the filter cartridge 41 and enters the output pipe 22. However, the silicone rubber will flow outward along the side with the smallest permeation pressure, and the impurities intercepted will gather on the side of the filter cartridge 41 facing the output pipe 22, causing this side to be blocked the fastest. The filtering speeds of the various sides of the filter cartridge 41 are different, which affects the filtering speed. For this reason, in one embodiment, the filter cartridge 41 can be rotatably connected to the input pipe 11; the filter assembly 4 also includes a driving member 42, which is connected to the filter cartridge 41 and the input pipe 11 and / or the output pipe 22, and is used to drive the filter cartridge 41 to rotate around its own axis. It should be understood that the filter cartridge 41 can be fixedly connected to the input pipe 11.

[0050] In this embodiment, by rotatably connecting the filter cartridge 41 to the input pipe 11, the driving member 42 can drive the filter cartridge 41 to rotate relative to the input pipe 11. When the filter cartridge 41 rotates, the silicone rubber between the filter cartridge 41 and the outer wall of the input pipe 11 can be stirred to prevent part of the silicone rubber from staying in the gap between the filter cartridge 41 and the input pipe 11. At the same time, the rotating filter cartridge 41 can reduce the adsorption of impurities on the filter cartridge 41 and reduce the speed at which impurities clog the filter cartridge 41. At the same time, the rotation of the filter cartridge 41 will cause the filter cartridge 41 to continuously change toward one side of the input pipe 11 to prevent one side of the filter cartridge 41 from being clogged too quickly.

[0051] In order to achieve a rotational connection between the filter cartridge 41 and the input pipe 11, in one embodiment, the filter assembly 4 also includes a first connecting member 43, which is arranged at one end of the filter cartridge 41. The first connecting member 43 includes a first bearing 431, and the inner ring of the first bearing 431 is connected to the input pipe 11, and the outer ring of the first bearing 431 is connected to the filter cartridge 41.

[0052] By providing the first bearing 431 , the filter cartridge 41 is rotatably connected to the input pipe 11 via the first bearing 431 . Meanwhile, the first bearing 431 can reduce the resistance of the filter cartridge 41 when it rotates.

[0053] Among them, the driving member 42 can be a combination of a motor and a gear transmission mechanism, a combination of a motor and a sprocket transmission mechanism, a combination of a motor and a belt transmission mechanism, etc. Specifically, in one embodiment, the outer ring of the first bearing 431 is provided with an external gear; the driving member 42 includes a driving motor 421 and a driving gear 422, the driving motor 421 is connected to the input pipe 11 and / or the sleeve 21, the driving gear 422 is connected to the output shaft of the driving motor 421, and is meshed with the outer ring of the first bearing 431, and is connected to the filter cartridge 41 via the outer ring of the first bearing 431.

[0054] When the filter cartridge 41 needs to be driven to rotate, the drive motor 421 is turned on. The drive motor 421 drives the ring gear on the first bearing 431 to rotate via the drive gear 422. The ring gear drives the filter cartridge 41 to rotate, thereby realizing the rotation of the filter cartridge 41 relative to the input pipe 11 and the sleeve 21.

[0055] Since the first bearing 431 cannot prevent the fluid from flowing out from one end of the filter cartridge 41, in order to rotationally seal one end of the filter cartridge 41, in one embodiment, the first connecting member 43 also includes a first connecting ring 432 and a first sealing ring 433. The first connecting ring 432 connects the outer ring of the first bearing 431 and the filter cartridge 41. The first sealing ring 433 is sleeved on the input pipe 11 and is arranged between the first connecting ring 432 and the input pipe 11.

[0056] Through the above arrangement, when the filter cartridge 41 rotates, the filter cartridge 41 drives the first connecting ring 432 to rotate, and the rotating first connecting ring 432 fits the inner wall of the input pipe 11 through the first sealing ring 433. One end of the filter cartridge 41 and the inner wall of the input pipe 11 are linearly sealed through the first connecting ring 432 and the first sealing ring 433 to prevent the fluid from flowing out through the end of the filter cartridge 41.

[0057] In one embodiment, a first sealing ring 434 is disposed between the outer wall of the first connecting ring 432 and the sleeve 21 .

[0058] In order to make the filter cartridge 41 rotate more smoothly, it is necessary to support the other end of the rotating filter cartridge 41. To this end, in one of the embodiments, the filter assembly 4 also includes a second connecting member 44, which is arranged at the other end of the filter cartridge 41. The second connecting member 44 includes a second bearing 441 and a second connecting ring 442. The second bearing 441 is sleeved on the input pipe 11 and the outer ring is connected to the filter cartridge 41. The second connecting ring 442 is connected to the inner ring of the second bearing 441 and connected to the input pipe 11.

[0059] By arranging a second bearing 441 and a second connecting ring 442 at the other end of the filter cartridge 41, the inner ring of the second bearing 441 is fixed to the input pipe 11 via the second connecting ring 442, and the outer ring is connected to the filter cartridge 41, so that the other end of the rotating filter cartridge 41 can be supported by the second bearing 441 and the second connecting ring 442, thereby realizing rotational support for the other end of the filter cartridge 41, and making the filter cartridge 41 rotate more smoothly.

[0060] Since the second bearing 441 and the second connecting ring 442 cannot prevent the fluid from flowing out from the other end of the filter cartridge 41, in order to rotationally seal the other end of the filter cartridge 41, in one embodiment, the second connecting member 44 also includes a third connecting ring 443 and a third sealing ring 444, and the third connecting ring 443 connects the outer ring of the second bearing 441 and the other end of the filter cartridge 41, and the second bearing 441 is connected to the filter cartridge 41 via the third connecting ring 443; the third sealing ring 444 is sleeved on the second connecting ring 442 and seals against the inner wall of the second connecting ring 442.

[0061] In this embodiment, the outer ring of the second bearing 441 is connected to the filter cartridge 41 via the third connecting ring 443, and the third connecting ring 443 and the outer walls of the input pipe 11 and the second connecting ring 442 are sealed by the third sealing ring 444, so that the other end of the filter cartridge 41 is sealed via the third connecting ring 443, the third sealing ring 444 and the second connecting ring 442.

[0062] The gap between the other end of the filter cartridge 41 and the sleeve 21 is sealed. To this end, in one embodiment, the second connecting member 44 also includes a fourth sealing ring 445 , which is sleeved on the third connecting ring 443 , and the outer ring is sealed against the inner wall of the sleeve 21 .

[0063] By setting the fourth sealing ring 445, the fourth sealing ring 445 can seal the gap between the outer wall of the third connecting ring 443 and the inner wall of the sleeve 21 to prevent the fluid from flowing to the other end of the filter cartridge 41, and when the inner wall of the third connecting ring 443 is hollow, the fourth sealing ring 445 located outside the third connecting ring 443 can provide support for the third connecting ring 443.

[0064] In one embodiment, a second sealing ring 446 is disposed between the inner wall of the second connecting ring 442 and the input pipe 11 .

[0065] It should be understood that the filter screen 12 can be detachably embedded in the first window 11a, or can be fixed to the first window 11a. Specifically, in one embodiment, one end of the sleeve 21 is closed and the other end is open. The open end of the sleeve 21 is located at the other end of the input pipe 11. The output assembly 2 also includes an end cover 23, which is annular and slidably sleeved on the input pipe 11. The end cover 23 is arranged relative to the open end of the sleeve 21 and is detachably connected to the sleeve 21. The second connecting ring 442 is slidably sleeved on the input pipe 11. , and slides against the inner wall of the second bearing 441, the second connecting ring 442 is connected to the end cover 23, and the third sealing ring 444 slides against the inner wall of the second connecting ring 442; the input component 1 also includes a sleeve 13 and a fixing member 14, the sleeve 13 is slidably mounted on the input pipe 11, and at least one second window 13a is opened relative to the first window 11a, the filter screen 12 is detachably arranged on the second window 13a, and is slidably arranged on the first window 11a through the sleeve 13, and the fixing member 14 connects the sleeve 13 and the second connecting ring 442.

[0066] After the filter screen 12 has been used for a period of time, it needs to be disassembled for cleaning or replacement to avoid excessive fluid pressure loss caused by the filter screen 12. For this reason, in the present embodiment, a structure for repairing the filter screen 12 is provided; when the filter screen 12 needs to be repaired, the end cover 23 is removed from the input pipe 11, and then the end cover 23 is slid so that the end cover 23 slides away from the input pipe 11, and the end cover 23 drives the second connecting ring 442 to slide, and the second connecting ring 442 drives the sliding sleeve 13 and the filter screen 12 to slide away from the input pipe 11, thereby realizing the separation of the filter screen 12 from the input pipe 11. At this time, the filter screen 12 can be replaced or cleaned, and at the same time, a cleaning tool can be inserted through the open end of the sleeve 21 to clean the filter cartridge 41 in the sleeve 21, so that the filter cartridge 41 and the filter screen 12 can be maintained; at the same time, in the process of the sliding sleeve 13 sliding away from the input pipe 11, the liquid intercepted by the filter screen 12 can be removed. The impurities are driven to leave the input pipe 11; after the maintenance of the filter screen 12 is completed, the sliding sleeve 13 is slidably mounted on the input pipe 11, and the second connecting ring 442, the third sealing ring 444, the sliding sleeve 13, and the filter screen 12 are pushed into the sleeve 21 through the end cover 23. When the end cover 23 slides to abut the sleeve 21, at this time, the second connecting ring 442 is slidably inserted into the inner ring of the second bearing 441 and supports the inner ring of the second bearing 441. The third sealing ring 444 fits the inner wall of the third connecting ring 443 and blocks the gap between the third connecting ring 443 and the second connecting ring 442 to prevent the silicone rubber from sliding in the direction close to the second bearing 441 and preventing the silicone rubber from contacting the second bearing 441; when the end cover 23 slides to abut the sleeve 21, the sliding sleeve 13 slides to a preset position. At this time, the filter screen 12 is facing the first window 11a of the input pipe 11, and the filter screen 12 filters the silicone rubber discharged through the first window 11a.

[0067] In order to seal the two ends of the sleeve 13 to prevent the fluid from leaking directly outward from the two ends of the sleeve 13, in one embodiment, the input component 1 also includes a retaining ring 15 and a fifth sealing ring 16. The retaining ring 15 is fixedly sleeved on the input pipe 11 and is arranged on the side of the first window 11a away from the end cover 23. The fifth sealing ring 16 is arranged between the retaining ring 15 and the end of the sleeve 13 to seal the gap between the retaining ring 15 and the sleeve 13.

[0068] In this embodiment, the end of the sleeve 13 that penetrates into one end of the sleeve 21 is provided with a retaining ring 15 and a fifth sealing ring 16. The retaining ring 15 is fixed to the input pipe 11. During the process of the sleeve 13 sliding into the sleeve 21, the sleeve 13 gradually abuts against the fifth sealing ring 16 and squeezes the fifth sealing ring 16. Through the fifth sealing ring 16 and the retaining ring 15, one end of the sleeve 13 can be sealed.

[0069] In the process of sealing the other end of the sleeve 13, since the fourth connecting ring 141 needs to drive the sleeve 13 to slide in and out of the sleeve 21, the fourth connecting ring 141 needs to be connected to the sleeve 13. However, when a fixed connection is adopted, in order to seal the sealing ring set between the sleeve 13 and the input pipe 11, if the extrusion of the sealing ring between the sleeve 13 and the input pipe 11 is too large, the sleeve 13 will not be able to slide relative to the input pipe 11, and if it is too small, it will not be able to seal the silicone rubber with a certain pressure. Therefore, in one of the embodiments, the fixing member 14 includes a fourth connecting ring 141, a spring 142, and a sixth sealing ring 143. The fourth connecting ring 141 is slidably sleeved on the input pipe 11 and is arranged between the sleeve 13 and the second connecting ring 442. The fourth connecting ring 141 is connected to the second connecting ring 442. The fourth connecting ring 141 faces the sleeve 13. A tapered hole is provided on one side, and the inner diameter of the tapered hole gradually decreases in the direction away from the sleeve 13. An annular protrusion 144 is formed outwardly on the peripheral wall of the fourth connecting ring 141. A collar 17 is formed outwardly on one end of the sleeve 13 facing the fourth connecting ring 141. The collar 17 cooperates and is slidably sleeved on the annular protrusion 144. A set screw 18 is provided on the collar 17. The set screw 18 is threadedly connected to the collar 17 and is arranged between the annular protrusion 144 and the second connecting ring 442. The spring 142 is sleeved on the input pipe 11 and is arranged between the sleeve 13 and the annular protrusion 144. The sixth sealing ring 143 is sleeved on the input pipe 11 and is arranged between the sleeve 13 and the fourth connecting ring 141. One end of the sixth sealing ring 143 is connected to the sleeve 13 and the other end is tapered. The outer diameter of the other end of the sixth sealing ring 143 gradually decreases in the direction approaching the fourth connecting ring 141.

[0070] In this embodiment, the sleeve 13 and the fourth connecting ring 141 are connected by the annular protrusion 144, the ring 17 and the fixing screw 18. The annular protrusion 144 and the inner wall of the ring 17 are slidably matched, so that the fourth connecting ring 141 can slide relative to the sleeve 13. During the sliding process, the sleeve 13 and the fourth connecting ring 141 increase or decrease. By setting the fixing screw 18, the fixing screw 18 is threadedly connected to the ring 17 and is set between the annular protrusion 144 and the second connecting ring 442. The annular protrusion 144 can be limited from disengaging from the ring 17, so that the distance between the sleeve 13 and the fourth connecting ring 141 is within a preset range.

[0071] When the sleeve 13 is slidably inserted into the sleeve 21, one end of the sleeve 13 first abuts against the retaining ring 15 via the fifth sealing ring 16. At this time, the sleeve 13 cannot move further and continues to slide the end cover 23. The end cover 23 pushes the fourth connecting ring 141 to continue to move. The fourth connecting ring 141 approaches the sleeve 13 and squeezes the spring 142 and the sixth sealing ring 143. Since the outer diameter of the other end of the sixth sealing ring 143 gradually decreases in the direction approaching the fourth connecting ring 141, when the fourth connecting ring 141 squeezes the sixth sealing ring 143, the sixth sealing ring 143 will be tightly attached to the other end of the input pipe 11 and the sleeve 13, so that the other end of the sleeve 13 can be tightly sealed.

[0072] When the sleeve 13 is removed, the end cover 23 slides in the direction of separating from the input pipe 11, driving the second connecting ring 442 and the fourth connecting ring 141 to slide. At this time, the fourth connecting ring 141 slides away from the sleeve 13. At this time, the extrusion force applied to the sixth sealing ring 143 is released. At this time, the sixth sealing ring 143 is reset under the action of its own elastic force, reducing the extrusion and friction between the input pipe 11, making it easier for the sleeve 13 to slide away from the input pipe 11; in the process of the fourth connecting ring 141 sliding away from the sleeve 13, until the fixing screw 18 abuts the annular protrusion 144, at this time, the fixing screw 18 drives the ring 17 and the sleeve 13 to slide away from the input pipe 11.

[0073] It should be understood that the end cover 23 and the second connecting ring 442 can be directly connected or connected via other structures. Specifically, in one embodiment, the second connecting member 44 also includes a plurality of screws 447 and a plurality of nuts 448. One end of the screw 447 is connected to the second connecting ring 442, and the other end can be rotated to pass through the end cover 23. The plurality of nuts 448 are respectively threadedly connected to the plurality of screws 447, and each screw 447 is provided with two nuts 448 located at both ends of the end cover 23.

[0074] In this embodiment, the second connecting ring 442 and the end cover 23 are connected by means of a screw 447 and a nut. Moreover, in this embodiment, the position of the nut 448 relative to the screw 447 can be adjusted to adjust the position between the end cover 23 and the second connecting ring 442, so as to adjust the distance between the sleeve 13 and the fourth connecting ring 141. When the end cover 23 is adjusted to be fixed to the sleeve 21, the fourth connecting ring 141 squeezes the sixth sealing ring 143 with an extrusion force, thereby finally achieving the adjustment of the sealing performance between the sixth sealing ring 143 and the input pipe 11.

[0075] It should be understood that the conveying component 3 can be a piston-type conveying device, a pumping-type conveying device, etc. Specifically, in one embodiment, the conveying component 3 includes a rotating shaft 31, an auger 32 and a rotating motor 33. The rotating shaft 31 can be rotatably connected to the input pipe 11. The auger 32 is built into the input pipe 11 and connected to the rotating shaft 31. The rotating motor 33 is fixed to the input pipe 11, and the output shaft of the rotating motor 33 is connected to the rotating shaft 31.

[0076] In this embodiment, when the silicone rubber needs to be transported, the rotating motor 33 is started, the rotating motor 33 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the auger 32 to rotate. The rotating auger 32 can push the silicone rubber to move in the input pipe 11, and the conveying rate can be changed by adjusting the rotation speed of the rotating motor 33.

[0077] The present invention also relates to a pipeline transportation method for silicone rubber processing, using the above-mentioned pipeline transportation device for silicone rubber processing, comprising the following steps:

[0078] The conveying component 3 drives the material to move in the input pipe 11, and drives the silicone rubber to move from one end of the input pipe 11 to the other end;

[0079] The silicone rubber is pushed through the filter screen 12 and enters between the filter screen 12 and the filter cartridge 41;

[0080] The silicone rubber is pushed through the filter cartridge 41 and enters between the filter cartridge 41 and the sleeve 21;

[0081] The silicone rubber enters the output pipe 22 from the sleeve 21 under extrusion.

[0082] It should be understood that the above steps are not in any particular order and their order can be adjusted as needed.

[0083] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
