Description

TECHNICAL FIELD

[0002] Epoxy resin refers to an organic high molecular compound containing two or more epoxy groups in the molecule, which can be crosslinked with various types of curing agents to form insoluble and infusible high polymers with three-dimensional network structure, and is widely used in the fields of automobile, ship, electronic industry, etc. In the production process of epoxy resin, the water content in the epoxy resin is high, so it is necessary to filter and separate the water in the epoxy resin.

[0003] Traditional lipid-water separation mostly adopts the way of heating evaporation, which realizes the evaporation separation of water by directly heating the container containing epoxy resin to make the water in the epoxy resin boil and evaporate.

In addition, since the epoxy resin also contains bubbles, the volume of the bubbles is easily expanded by heating during the evaporation processing, which leads to explosion and rupture, causing the epoxy resin to splash out, affecting the normal processing of the epoxy resin.

[0036] The epoxy resin is introduced into the defoaming box 21, and then is divided by the plurality of flow guide hoppers 22 and enters the flow guide hoppers 22, the impurities in the epoxy resin are intercepted and filtered by the filter screen, the squeezing roller 23 is driven to rotate by the external driving device, the epoxy resin between the two squeezing rollers 23 is squeezed by the rotation of the squeezing roller 23, and the bubbles mixed in the epoxy resin are squeezed out, so that the situation that the bubbles are expanded and exploded due to heating in the subsequent evaporation process is avoided.

[0037] Please refer to Figure 4 and Figure 5 In the embodiment, the first evaporation mechanism 3 comprises an evaporation cylinder 31, the middle part of the upper end surface of the ladder-shaped frame 5 is fixedly connected with the evaporation cylinder 31, the bottom of the inner cavity of the evaporation cylinder 31 is in a conical shape, so that the epoxy resin can normally flow out of the evaporation cylinder 31 after evaporation is completed, and the epoxy resin is prevented from accumulating at the bottom of the evaporation cylinder 31, the upper part of the evaporation cylinder 31 is communicated with the feeding pipe 32, a mesh plate 33 is fixedly connected in the upper part of the inner cavity of the evaporation cylinder 31, a plurality of arc-shaped material shifting pieces 35 are fixedly connected in the circumferential direction on the upper end surface of the mesh plate 33 through a rotating seat 34, the upper part of the rotating seat 34 is in an inverted conical shape, a hemisphere is fixedly connected to the upper part of the rotating seat 34, and a waterproof coating is sprayed on the upper surface wall of the rotating seat 34 to prevent the epoxy resin from adhering to the rotating seat 34, a plurality of evaporation fins 36 are fixedly connected at equal intervals in the inner cavity of the evaporation cylinder 31, the lower part of the evaporation fin 36 is in an arrowhead shape, can play a guiding role on the epoxy resin adhering to the surface of the evaporation fin 36, and facilitates the epoxy resin to flow off from the evaporation fin 36, a plurality of strip-shaped boxes 37 are fixedly connected at equal intervals in the front part and the rear part of the inner cavity of the evaporation cylinder 31 and between adjacent two evaporation fins 36, a plurality of spiral vanes 38 are rotatably connected at equal intervals in the strip-shaped box 37, air outlet grooves are formed in the opposite sides of the two strip-shaped boxes 37, a guide plate 39 is fixedly connected in the upper part of the inner cavity of the evaporation cylinder 31 and above the evaporation fin 36, a spiral pipe 310 is sleeved and communicated outside the evaporation cylinder 31, a fan is arranged at the upper end of the spiral pipe 310, and a water collecting box 311 is fixedly connected below the lower end of the spiral pipe 310.

[0038] After the bubbles mixed in the epoxy resin are removed by the bubble removing mechanism 2, the epoxy resin enters the first evaporation mechanism 3 through the feeding pipe 32. The epoxy resin enters the evaporation cylinder 31 and falls onto the net plate 33. Then, the rotating seat 34 is controlled to rotate by the driving device, and the rotating seat 34 in turn drives the arc-shaped scraping piece 35 to rotate. The arc-shaped scraping piece 35 spreads the epoxy resin evenly on the net plate 33. Then, the epoxy resin drops onto the guide plate 39 through the mesh holes of the net plate 33. Then, the epoxy resin drops onto the surface of the evaporation fin 36 through the inclined surface of the guide plate 39. The evaporation fin 36 is internally provided with a heating wire. The heating wire is controlled to operate so that the evaporation fin 36 generates heat, thereby heating the epoxy resin attached to the surface of the evaporation fin 36. At the same time, the spiral fan blade 38 operates to drive the airflow in the evaporation box to flow. The airflow flows from the surface of the evaporation fin 36. The epoxy resin is spread on the surface of the evaporation fin 36 to increase the contact area with air. The airflow in contact with the epoxy resin is increased in flow rate, so that the water mixed in the epoxy resin can be quickly heated and evaporated, the evaporation speed of water is improved, and the epoxy resin and water can be completely separated. At the same time, the air blower is started to operate to drive the airflow in the spiral pipe 310 to flow. The water vapor after evaporation is sucked into the spiral pipe 310. The water vapor extracted is discharged through the spiral pipe 310. The part of the water vapor that appears to be liquefied in the spiral pipe 310 enters the water collecting box 311 for collection.

[0039] Please refer to Figure 2 and Figure 6 In the embodiment, the second evaporation mechanism 4 includes driving rollers 41. The right part of the upper end surface of the trapezoidal frame 5 is rotationally connected with the driving rollers 41 through vertical frames. The two driving rollers 41 are jointly sleeved with a metal strip belt 42. The upper end surface of the trapezoidal frame 5 is fixedly connected with a heating plate 47 below the upper transverse section of the metal strip belt 42. The upper end surface of the bottom plate 1 is fixedly connected with a support plate. The front end surface of the support plate is rotationally connected with a spreading cylinder 43 that is attached to the surface of the metal strip belt 42 above the metal strip belt 42. The front end surface of the support plate is fixedly connected with a strip-shaped pipe 44 that is attached above the spreading cylinder 43 through a reciprocating telescopic rod. The lower part of the evaporation cylinder 31 is communicated with a conveying pipe. The strip-shaped pipe 44 is communicated with the right end of the conveying pipe. The front end surface of the support plate is fixedly connected with a scraper plate 45 that is attached to the lower surface of the metal strip belt 42. The upper end surface of the bottom plate 1 is fixedly connected with a condensing plate 46 above the metal strip belt 42. The condensing plate 46 is gradually inclined to the side close to the metal strip belt 42 from right to left. The left part of the lower end surface of the condensing plate 46 is fixedly connected with a collecting box. The upper end surface of the bottom plate 1 is fixedly connected with a collecting box 6 below the metal strip belt 42.

[0040] The epoxy resin is evaporated by the first evaporation mechanism 3 and then enters the second evaporation mechanism 4 through the conveying pipe for further evaporation processing. The epoxy resin is conveyed to the strip-shaped pipe 44, and the strip-shaped pipe 44 is driven by the reciprocating rod to move back and forth on the surface of the coating cylinder 43 to transfer the epoxy resin to the coating cylinder 43. Meanwhile, the driving roller 41 is driven by the external driving source to rotate, and then the metal sheet belt 42 is driven by the driving roller 41 to rotate. The coating cylinder 43 re-coats the epoxy resin on the outer surface of the metal sheet belt 42, and the heating plate 47 is powered to heat the metal sheet belt 42. The metal sheet belt 42 then transmits heat to the epoxy resin on the surface of the metal sheet belt 42, further heating and evaporating the water in the epoxy resin. The water evaporates and rises to the condensing plate 46 to be liquefied. The water droplets flow to the left on the inclined surface of the condensing plate 46 under the left-low and right-high inclined state, and then enter the collection box to collect the separated water vapor. Then, the epoxy resin separated by the metal sheet belt 42 moves to the lower part of the metal sheet belt 42 under the action of gravity, and then falls into the collection box 6. The epoxy resin adhering to the surface of the metal sheet belt 42 is scraped off by the scraper plate 45 and then falls into the collection box 6.
