Description

Technical Field

[0001] The utility model relates to the technical field of resin production and processing, in particular to a filter protection device for a resin production room. Background Art

[0002] Resin refers to an organic substance with an uncertain but usually high relative molecular weight, which is solid, medium solid, pseudo-solid, or sometimes liquid at room temperature. In a broad sense, it refers to a polymer or prepolymer used as a plastic base material. Resin has a softening or melting temperature range, tends to flow under the action of external force, and often has a shell-like shape when broken. It is generally insoluble in water but soluble in organic solvents.

[0003] Most of the existing resin filter protection devices can only protect the filter from the outside, thereby reducing the contact between the resin and the external environment during the filtration process, thereby ensuring the normal filtration work. However, it cannot ensure that the temperature of the resin can always be maintained at a high temperature during filtration. When the resin temperature is low, its viscosity is greater, which can easily lead to reduced filtration efficiency.

[0004] Based on this, the utility model designs a filter protection device for a resin production room to solve the above problems. Utility Model Content

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] Reference Figure 1 and Figure 2 A filter protection device for a resin production room includes a support frame 1, a protection box 2 and a filter. The filter includes a filter cartridge 3, a cone bucket 4, a drain pipe 5, a butterfly valve 6, a top cover 7, a stirring motor 8, a stirrer 9 and a feed pipe 10. The cone bucket 4 is arranged at the bottom of the filter cartridge 3, the butterfly valve 6 is installed on the drain pipe 5, the top end of the drain pipe 5 is connected to the bottom end of the cone bucket 4, the stirrer 9 is coaxially fixed on the output shaft of the stirring motor 8, the feed pipe 10 is connected to the top cover 7, the stirring motor 8 is fixedly connected to the top cover 7, the stirrer 9 is located inside the filter cartridge 3, and the stirrer 9 and the filter cartridge 3 are connected. There is a small gap between the inner walls to facilitate the natural fall of filtered impurities. The agitator 9 is composed of six plates and a rotating shaft. The six plates are evenly installed around the rotating shaft. The top of the protective box 2 is fixedly connected with an upper cover 11. The interior of the upper cover 11 is provided with holes and grooves that are compatible with the top cover 7, so that the upper cover 11 can be installed more tightly. Heaters 12 are fixedly connected to the four corners of the interior of the protective box 2 to heat the resin being filtered and increase its filtering effect. The bottom side of the protective box 2 is connected to a discharge pipe 15 to discharge the filtered resin well.

[0027] Reference Figure 3 and Figure 4A receiving groove 16 is fixedly connected to the inner side of the support frame 1, and a placement rack 17 is arranged on the top of the receiving groove 16. A filter screen 18 is arranged on the inner side of the placement rack 17, which can filter a small amount of discharged resin and impurities so that the impurities remain on the filter screen 18. The filtered resin is refluxed through the delivery pump 14 and the return pipe 13, so that it can be repeatedly filtered. The top of the top cover 7 is connected to one side of the bottom of the receiving groove 16 with a return pipe 13, and the outer wall of the protection box 2 is fixedly connected to the delivery pump 14. The return pipe 13 is divided into two parts, and the two parts are respectively connected to the liquid inlet and liquid outlet of the delivery pump 14. The filter screen 18 is located directly below the sewage pipe 5, and the placement rack 17 is clamped on the top of the receiving groove 16, which is convenient for disassembly and assembly of the placement rack 17 and the filter screen 18, and convenient for cleaning the filter screen 18.

[0028] The implementation principle of this embodiment is as follows: when in use, the resin to be filtered is transported from the feed pipe 10 to the inside of the filter cartridge 3, and then the stirring motor 8 is started. The stirring motor 8 continuously drives the stirrer 9 to rotate, so that the resin enters the inside of the protective box 2 from the filter cartridge 3, and is finally discharged through the discharge pipe 15. Then, the impurities fall into the inside of the cone bucket 4 under the action of gravity. After a certain period of filtration, the butterfly valve 6 is opened, and the impurities at the bottom of the cone bucket 4 and a small amount of resin are discharged from the drain pipe 5 through the drain pipe 5. After discharge, the butterfly valve 6 is closed, so that the impurities remain on the filter screen 18, and then the resin filtered by the filter screen 18 falls into the receiving tank 16, and then the resin inside the receiving tank 16 is transported to the inside of the filter cartridge 3 for filtration through the delivery pump 14 and the return liquid pipe 13. During the resin filtration process, four heaters 12 are started to heat the resin so that its temperature will not be too low during filtration.
