Description

TECHNICAL FIELD

[0001] The utility model relates to coalescing filter element technical field especially high strength coalescing filter element. BACKGROUND

[0002] Coalescing filter element is a kind of filtering equipment with coalescing material as medium, and it is the main element in coalescer that plays a filtering role. Tiny oil droplets dispersed in water or other liquids are captured by superfine fibers on the surface of oleophilic filter material, and coalesce to form larger oil beads. Since the density of oil beads is less than that of water, the coalesced oil beads automatically float to the top of the coalescer and flow out from the opening at the top of the coalescer. Water flows directly through the side wall of the filter material and flows outward, thereby achieving the effect of oil-water separation. In addition, the coalescing filter element can also filter out mechanical impurities in the medium.

[0003] The current coalescing filter element is usually composed of a mesh-shaped metal inner framework, a coalescing layer (wood pulp paper folding) and a nylon mesh cover. However, when the coalescing filter element is ventilated, if the ventilation volume is large, the wind pressure will also increase, causing the gap at a folding position of the coalescing layer to be blown open, and the gap beside it to become smaller, which cannot be fully filtered, resulting in a decrease in the filtering area of the coalescing layer and a reduction in the filtering effect. SUMMARY

[0004] In view of the deficiencies in the prior art, the present utility model provides a high-strength coalescing filter element, and the specific technical solutions are as follows:

[0005] The high-strength coalescing filter element includes a coalescing filter element body, which comprises an inner framework mesh, a foldable coalescing layer and a nylon mesh cover arranged in sequence from inside to outside. The nylon mesh cover is provided with a plurality of hot melt adhesive rings wrapped around the outer surface of the coalescing layer and arranged at intervals along the length direction of the filter element.

[0006] By heating the plurality of hot melt adhesive rings arranged at intervals along the length direction of the filter element, the hot melt adhesive is melted into the foldable coalescing layer, and then the filter element is cooled to solidify the coalescing layer with hot melt adhesive. This way, there are multiple supports in the gap of the coalescing layer along the length direction of the filter element, which improves the internal strength of the coalescing filter element and forces the gap in the coalescing layer to open, so that the gap in the coalescing layer is less likely to change during ventilation, indirectly improving the filtering efficiency.

[0007] Optionally, the outer side of the inner framework mesh is provided with a first non-stick adhesive paper for separating the hot melt adhesive from the inner framework mesh when the hot melt adhesive ring is melted. The nylon mesh cover is provided with a second non-stick adhesive paper for separating the hot melt adhesive from the nylon mesh cover when the hot melt adhesive ring is melted.

[0008] By adopting the above technical solutions, the first non-stick adhesive paper and the second non-stick adhesive paper are arranged to block the hot melt adhesive when the hot melt adhesive ring is melted, so that the hot melt adhesive cannot flow into the holes of the inner framework mesh and the nylon mesh cover to cause blockage.

[0009] Optionally, a lower end cover is fixed between the inner framework net and the bottom of the nylon net cover, the coalescing layer is abutted on the top of the lower end cover, an upper end cover is threaded between the top of the inner framework net and the nylon net cover, and the coalescing layer is abutted on the bottom of the upper end cover.

[0010] By adopting the above technical scheme, the first non-stick glue paper and other components in the filter core can be taken out by unscrewing the upper end cover, without affecting the normal filtration of the filter core.

[0011] Optionally, a counterweight ring is slidably arranged in the inner framework net, and a plurality of bristles for dredging the mesh of the inner framework net when the counterweight ring slides are fixed on the outer wall of the counterweight ring.

[0012] By adopting the above technical scheme, the counterweight ring will slide in the filter core after the filter core is upside down, and the counterweight ring after sliding can dredge the inner framework net by using the bristles, thereby reducing the working intensity of the staff in cleaning the filter core.

[0013] Optionally, a plurality of through holes are fixed in the counterweight ring and are arranged in a staggered manner with the bristles.

[0014] By adopting the above technical scheme, the medium in the filter core can flow into the inner framework net from the bristles along the through holes, so that the counterweight ring does not affect the filtration efficiency and effect of the filter core on the medium.

[0015] Optionally, a circular hole is formed in the center of the lower end cover and the upper end cover, and the diameter of the counterweight ring is greater than the inner diameter of the circular hole of the lower end cover and the upper end cover.

[0016] By adopting the above technical scheme, the counterweight ring will not naturally separate from the filter core under the blockage of the lower end cover and the upper end cover.

[0017] In summary, the utility model has at least one of the following beneficial effects:

[0018] 1. By heating a plurality of hot melt glue rings arranged at intervals along the length direction of the filter core, melting the hot melt glue into the foldable coalescing layer, and then cooling the filter core to solidify the coalescing layer with hot melt glue, a plurality of supports are arranged in the gap of the coalescing layer along the length direction of the filter core, the internal strength of the coalescing filter core is improved, and the gap in the coalescing layer is forced to open, so that the gap in the coalescing layer is not easy to change during the aeration process, and the filtration efficiency is indirectly improved.

[0019] 2. By the setting of the first non-stick glue paper and the second non-stick glue paper, the hot melt adhesive can be blocked when the hot melt adhesive ring melts, so that the hot melt adhesive cannot flow into the holes of the inner framework net and the nylon net cover to cause blockage, and the first non-stick glue paper and other components in the filter core can be taken out by rotating the upper end cover, without affecting the normal filtration of the filter core, and after the filter core is upside down, the counterweight ring can slide in the filter core, and the counterweight ring after sliding can use the bristles to dredge the inner framework net, reduce the work intensity of the staff for cleaning the filter core in the later period, and be convenient and practical.

[0026] The utility model is further explained in detail as follows. Figures 1-5 The utility model is further explained in detail as follows.

[0027] The utility model embodiment discloses high-strength coalescing filter core, refer to Figures 1-3 , including coalescing filter core body, inner framework net 1, foldable coalescing layer 11 and nylon net cover 12 that are sequentially arranged from inside to outside and form the coalescing filter core body, wherein the inner framework net 1 can be stainless steel punched spiral net, which can support the inside of the coalescing filter core.

[0028] Refer to Figures 1-3 , the coalescing layer 11 can be wood pulp paper in folded state, the coalescing layer 11 is one layer and more than one layer, after the coalescing layer 11 is arranged in multiple layers, the separation and filtration effect can be improved, and since the coalescing layer 11 is foldable and has ductility and elasticity, the coalescing layer 11 arranged in multiple layers can be relatively conveniently inserted between the inner framework net 1 and the nylon net cover 12 after being folded, and the nylon net cover 12 can protect the coalescing layer 11.

[0029] With reference to Figures 2-4 , the nylon mesh sleeve 12 is provided with a plurality of hot melt adhesive rings 2 wrapped outside the coalescence layer 11 and arranged along the length direction of the filter element. The hot melt adhesive rings 2 are annularly wrapped outside the coalescence layer 11, and the plurality of hot melt adhesive rings 2 are arranged along the length direction of the filter element. In the subsequent high-temperature heating process, the hot melt adhesive rings 2 melt into the foldable coalescence layer 11, and then the filter element is naturally cooled to solidify the coalescence layer 11 with hot melt adhesive. There are a plurality of supports in the gap of the coalescence layer 11 along the length direction of the filter element, which improves the internal strength of the coalescence filter element, and forces the gap in the coalescence layer 11 to open, so that the gap in the coalescence layer 11 is not easy to change during aeration, and the filtration area of the coalescence layer 11 is not easy to change during aeration, thereby indirectly improving the filtration efficiency.

[0030] With reference to Figures 2-4 , the inner framework net 1 is provided with a first non-adhesive paper 3 for separating the hot melt adhesive from the inner framework net 1 when the hot melt adhesive ring 2 melts. The nylon mesh sleeve 12 is provided with a second non-adhesive paper 31 for separating the hot melt adhesive from the nylon mesh sleeve 12 when the hot melt adhesive ring 2 melts. The first non-adhesive paper 3 and the second non-adhesive paper 31 can block the hot melt adhesive when the hot melt adhesive melts, so that the hot melt adhesive cannot flow into the holes of the inner framework net 1 and the nylon mesh sleeve 12 to cause blockage. The first non-adhesive paper 3 and the second non-adhesive paper 31 can be non-adhesive paper bodies such as release paper.

[0031] With reference to Figure 1 , Figure 2 and Figure 4 , the lower end cover 4 is fixed between the bottom of the inner framework net 1 and the nylon mesh sleeve 12. The coalescence layer 11 is abutted on the top of the lower end cover 4. The upper end cover 41 is threadedly arranged between the top of the inner framework net 1 and the nylon mesh sleeve 12. The coalescence layer 11 is abutted on the bottom of the upper end cover 41. The lower end cover 4 can connect and fix the inner framework net 1 and the nylon mesh sleeve 12. The upper end cover 41 is threadedly connected to the top of the filter element, which facilitates the subsequent workers to unscrew the upper end cover 41 to take out the first non-adhesive paper 3 and the second non-adhesive paper 31 in the filter element, so that the first non-adhesive paper 3 and the second non-adhesive paper 31 do not affect the normal filtration of the filter element.

[0032] With reference to Figure 1 , Figure 4 and Figure 5The filter core is provided with a counterweight ring 5 slidingly arranged in the inner framework net 1, and a plurality of bristles 51 for dredging the mesh of the inner framework net 1 when the counterweight ring 5 slides are fixedly arranged on the outer side wall of the counterweight ring 5. Since the filter core filters the medium from inside to outside, the holes in the inner framework net 1 are easily blocked by mechanical impurities in the medium after long-time use. When the mechanical impurities need to be cleaned, the staff can turn over the filter core upside down, and the counterweight ring 5 slides in the filter core under the action of gravity. The counterweight ring 5 after sliding can dredge the inner framework net 1 by using the bristles 51. Then the staff can flush the filter core by using water flow. The mechanical impurities brushed off by the bristles 51 in the inner framework net 1 can be flushed out by the water flow, so as to reduce the difficulty and working strength of the staff in cleaning the inside of the filter core.

[0033] With reference to Figure 1 , Figure 4 and Figure 5 , a plurality of through holes 52 are fixedly arranged in the counterweight ring 5 and are arranged in a staggered manner with the bristles 51. The medium in the filter core can flow into the inner framework net 1 from the bristles 51 along the through holes 52, so that the counterweight ring 5 does not affect the filtering efficiency and effect of the filter core on the medium.

[0034] With reference to Figure 1 , Figure 4 and Figure 5 , a circular hole is arranged at the center of the lower end cover 4 and the upper end cover 41. The diameter of the counterweight ring 5 is greater than the inner diameter of the circular hole of the lower end cover 4 and the upper end cover 41, so that the counterweight ring 5 cannot naturally separate from the filter core under the blockage of the lower end cover 4 and the upper end cover 41.

[0035] The implementation principle of the high-strength coalescing filter core is as follows:

[0036] In use, the coalescing filter core can be heated, so that the hot melt adhesive ring 2 melts into the foldable coalescing layer 11, and then the filter core is naturally cooled to solidify the coalescing layer 11 with hot melt adhesive. There are a plurality of supports in the gap of the coalescing layer 11 along the length direction of the filter core, which improves the internal strength of the coalescing filter core, and forces the gap in the coalescing layer 11 to open, so that the gap in the coalescing layer 11 does not change easily during aeration, and the filtering area of the coalescing layer 11 does not change easily during aeration, thereby indirectly improving the filtering efficiency.

[0037] After the filter core is cooled, the staff can rotate the upper end cover 41 to take out the first non-sticky adhesive paper 3 and the second non-sticky adhesive paper 31 in the filter core, so that the first non-sticky adhesive paper 3 and the second non-sticky adhesive paper 31 do not affect the normal filtration of the filter core.

[0038] Due to the filter element filters the medium from inside to outside, the holes of the inner skeleton net 1 are easy to be blocked by mechanical impurities in the medium after long time use, when the mechanical impurities need to be cleaned, the staff can reverse the filter element up and down, and make the counterweight ring 5 slide in the filter element, the counterweight ring 5 after sliding can use the bristles 51 to dredge the inner skeleton net 1, then the staff can use water flow to flush the filter element, the mechanical impurities in the inner skeleton net 1 brushed away by the bristles 51 can be flushed away by the water flow, thereby reducing the difficulty and working strength of the staff to clean the inside of the filter element.

Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some of the technical features.
