Description

Technical Field

[0001] The invention belongs to the field of separation technology, and specifically relates to a device with a rotating cylindrical filtering surface, and more particularly to a filtering system for UV viscosity-reducing glue, a filtering device and a preparation process thereof. Background Art

[0002] UV viscosity-reducing glue needs to be filtered during the preparation process. In the related art, when the UV viscosity-reducing glue is filtered with a scraper filter, since there are 10 or more gel blocks per square meter in the UV viscosity-reducing glue, the gel blocks will be stuck in the filter holes when pushed by the scraper due to their viscoelasticity, so that the gel blocks will be squeezed and torn into pieces when the scraper cleans and scrapes the surface of the filter. The broken gel clumps may form irregular fragments and be re-mixed into the glue liquid, resulting in an uneven internal structure of the glue liquid.

[0003] Therefore, since the scraper will crush the gel blocks blocking the filter when filtering the UV viscosity-reducing glue, causing the broken gel blocks to enter the UV viscosity-reducing glue, resulting in a technical problem of uneven internal structure of the UV viscosity-reducing glue, it is necessary to design a filtration system, filtration device and preparation process for UV viscosity-reducing glue.

[0065] In the preparation process of UV viscosity-reducing adhesive, photoinitiator is an important component. When producing the viscosity-reducing adhesive, the photoinitiator needs to be fully dispersed in the adhesive solution. In related technologies, UV photoinitiators (such as TPO-L) often cannot be fully dispersed, resulting in rapid cross-linking of monomers at local concentrations to form a dense cross-linked network, that is, the appearance of gel blocks. It is necessary to use filtration equipment to pre-filter the dispersed and mixed UV viscosity-reducing adhesive. However, the inventors found that when using traditional scraper filtration, the shear force causes the gel blocks to break. The broken gel clusters may form irregular fragments and re-mix into the adhesive solution, resulting in an uneven internal structure of the adhesive solution, affecting the quality of the UV viscosity-reducing adhesive.

[0066] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0067] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0068] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0069] like Figure 2 、 Figure 3 and Figure 4As shown, in at least one disclosed embodiment, a filtration system for UV viscosity-reducing glue is provided, comprising: a filter barrel 1, a plurality of rows of filter holes 11 are formed on its outer wall, and the outer wall of the barrel between each row of filter holes 11 is made of elastic material; a cleaning mechanism 2 is arranged outside the filter barrel 1 and moves around the filter barrel 1 to clean impurities on the filter holes 11; wherein the cleaning mechanism 2 comprises: at least one scraper 21 arranged parallel to the axial direction of the filter barrel 1, and a liquid outlet 22 is formed on the side of the scraper 21 facing the filter barrel 1, and the opening length of the liquid outlet 22 is adapted to the length of a row of filter holes 11; the cleaning mechanism 2 is connected to a pressurizing device, so that the pressure of the glue sprayed from the liquid outlet 22 squeezes the elastic outer wall of the filter barrel 1 to form a concave surface, so that the sprayed glue forms an inclined liquid flow, flushing away impurities stuck in the adjacent filter holes 11 on both sides of the concave surface, thereby achieving the removal of residual impurities in the filter holes 11, and preventing the scraper 21 from squeezing and tearing the gel blocks filtered out of the filter holes 11 during cleaning and scraping.

[0070] In this embodiment, when the glue liquid sprayed out from the liquid outlet 22 squeezes the portion without filter holes 11 between the two rows of filter holes 11 on the filter barrel 1, the portion without filter holes 11 is squeezed toward the inside of the filter barrel 1 to bulge, so that the sprayed glue forms an inclined liquid flow along the squeezed surface, and the impurities on the filter holes 11 on both sides are flushed away from the filter holes 11, thereby achieving the removal of the residual impurities in the filter holes 11, and preventing the scraper 21 from squeezing and tearing the gel blocks filtered out of the filter holes 11 when cleaning and scraping.

[0071] In this embodiment, the boosting device can be a boosting pump, etc. Specifically, the liquid outlet of the boosting pump is connected to the feed port 210 at the top of the scraper 21, and the filtered UV viscosity-reducing glue is pumped into the scraper 21 by pumping.

[0072] In this embodiment, the booster pump and the top feed port 210 of the scraper 21 can be connected by a hose, etc., and the driving motor 25 drives the transmission shaft 26 to rotate, so as to drive the toggle rod 28 to rotate through the linkage sleeve 27, and then drives the upper rotating ring 23 to rotate. After the rotating ring 23 rotates one circle, the driving motor 25 drives the transmission shaft 26 to reverse, so that the rotating ring 23 reverses one circle, and the cycle is repeated to avoid hose entanglement.

[0073] In this embodiment, the glue liquid sprayed out from the liquid outlet 22 is filtered UV viscosity-reducing glue (UV viscosity-reducing glue).

[0074] In this embodiment, the scraper 21 has a hollow structure inside and can be connected to an external pump body. The pump body is electrically connected to the control module. The control module controls the main body to draw the glue into the scraper 21 and spray it out from the liquid outlet 22. When the filtration starts, the cleaning mechanism 2 can be synchronously controlled to start.

[0075] In this embodiment, the glue to be filtered is filtered through the filter barrel 1, and the filtered impurities such as gel blocks will remain on the filter holes 11, causing the filter holes 11 to be blocked. At this time, when the glue sprayed out through the liquid outlet 22 squeezes the portion without filter holes 11 between the two rows of filter holes 11 on the filter barrel 1, the portion without filter holes 11 is squeezed toward the inner bulge of the filter barrel 1, so that the sprayed glue forms an inclined liquid flow along the squeezed surface, and the flow direction of the liquid flow is as follows: Figure 5 In the middle, impurities on the filter holes 11 on both sides are flushed away from the filter holes 11 to prevent the filter holes 11 from being blocked. At the same time, the curved surface of the scraper 21 can guide the liquid flow, so that the liquid flow can better flow to the impurities on the filter holes 11. After being pushed by the liquid flow, the impurities will detach from the filter holes 11 or reduce the adhesion. For example, the push of the liquid flow reduces the part of the gel block stuck in the filter hole 11, thereby reducing the adhesion between the gel block and the filter hole 11. At this time, the curved surface of the scraper 21 can contact the impurities with reduced adhesion and can smoothly scrape the impurities off the filter hole 11 completely to avoid the breakage of the impurities.

[0076] In this embodiment, the width of the liquid outlet 22 is smaller than the diameter of the filter hole 11 .

[0077] like Figure 3 As shown, in an optional embodiment, the filter barrel 1 is made of elastic material; a plurality of pairs of support bars 12 are vertically arranged on the inner wall of the filter barrel 1, and each pair of support bars 12 is arranged between two adjacent columns of filter holes 11; the edges of the support bars 12 are close to the edges of the corresponding columns of filter holes 11 to limit the opening size of the filter holes 11.

[0078] In this embodiment, the strength of the filter holes 11 on the filter barrel 1 is strengthened by the support bars 12. When the liquid flow squeezes the position where the filter holes 11 are not opened on the filter barrel 1, the filter holes 11 are prevented from being deformed, thereby ensuring the filtering effect of the filter holes 11. When the liquid outlet 22 moves to the filter holes 11, since the filter holes 11 can spray glue through some of the liquid outlets 22, the squeezing force received by the positions where the filter holes 11 are not opened in a row of filter holes 11 is reduced, thereby avoiding deformation.

[0079] In this embodiment, the filter barrel 1 can be made of 316L stainless steel with PTFE coating.

[0080] In this embodiment, when the liquid flow sprayed from the liquid outlet 22 enters the filter hole 11, the flow direction of the liquid flow is as follows: Figure 6 As shown in F, the glue attached to the filter hole 11 can be flushed away to prevent the glue from adhering to the inner wall of the filter hole 11 for a long time, to prevent the attached glue from continuously inducing local polymerization, and to prevent abnormal viscosity of the glue; using the same glue to clean the inner wall of the filter hole 11 can maintain the viscosity stability of the glue body and avoid sudden changes in thixotropy caused by airflow cleaning.

[0081] In this embodiment, the edges of the support bars 12 are close to the edges of the corresponding rows of filter holes 11 so that the width of the filter barrel 1 between a group of support bars 12 can be maximized as much as possible, making it easier for the liquid flow to squeeze this part of the filter barrel 1 and deform it.

[0082] like Figure 2 As shown, in an optional embodiment, the cleaning mechanism 2 includes: an upper rotating ring 23 and a lower rotating ring 24; the upper rotating ring 23 is rotatably set at the top of the filter barrel 1; the lower rotating ring 24 is rotatably set at the bottom of the filter barrel 1; the scraper 21 is vertically set between the upper rotating ring 23 and the lower rotating ring 24, the top end of the scraper 21 is connected to the upper rotating ring 23, and the bottom end of the scraper 21 is connected to the lower rotating ring 24.

[0083] In this embodiment, the scraper strip 21 starts to rotate by driving the upper rotating ring 23 to rotate.

[0084] In this embodiment, a small gap may be left between the scraper strip 21 and the outer wall of the filter barrel 1 .

[0085] like Figure 1 As shown, in an optional embodiment, the cleaning mechanism 2 further includes: a drive motor 25 and a transmission shaft 26; the drive motor 25 is electrically connected to the control module; one end of the transmission shaft 26 is connected to the drive motor 25, and the other end of the transmission shaft 26 is connected to a linkage sleeve 27; a toggle rod 28 is horizontally arranged on the linkage sleeve 27, and the toggle rod 28 contacts the protrusion 29 on the top surface of the upper rotating ring 23; the control module is configured to control the drive motor 25 to drive the transmission shaft 26 to rotate, so as to drive the toggle rod 28 to rotate through the linkage sleeve 27, thereby driving the upper rotating ring 23 to rotate; the linkage sleeve 27 is rotatably connected to the column 13 on the top surface of the filter barrel 1. One protrusion 29 can correspond to two toggle rods 28, one of which drives the rotating ring 23 to rotate clockwise, and the other toggle rod 28 drives the rotating ring 23 to rotate counterclockwise.

[0086] In this embodiment, the filter barrel 1 does not rotate.
