DETAILED DESCRIPTION

The design uses a shear pump 3 to shear the polyarylethernitrile particles out along the guide pipe 4 and the discharge pipe 5 into the body 1, and then the polyarylethernitrile particles are filtered and supported under the action of the filter component 10 to prevent the polyarylethernitrile particles from moving downward. At the same time, an aqueous solution is put into the body 1 through the water inlet pipe 2, and the polyarylethernitrile particles are dispersed under the action of the stirring component 6, and the polyarylethernitrile particles and the aqueous solution are stirred, so that the impurity inorganic salts wrapped in the polyarylethernitrile particles can be effectively stirred and washed out, thereby improving the yield. Since impurity inorganic salts such as potassium sulfide and potassium carbonate can be dissolved in the aqueous solution, after the impurities are washed out, they flow out from the discharge pipe 9 with the liquid, which makes it easy to clean the impurities. After the liquid is discharged, force is applied to the filter assembly 10 to move it longitudinally, so that the filter assembly 10 loses its filtering support for the polyarylethernitrile particles, allowing the polyarylethernitrile particles to be discharged. When the polyarylethernitrile particles are discharged, a vibration motor can be set on the body 1 as needed to speed up the outflow of the material. The inner diameter of the discharge pipe 9 can be set as needed to avoid material blockage.

[0022] Reference Figure 3 The lower side of the inner wall of the discharge port 64 is on the same horizontal plane as the lower side of the inner wall of the feed pipe 5. This design facilitates the polyarylethernitrile particles to flow out of the discharge port 64 along the inner wall of the feed pipe 5. In order to facilitate the discharge of the polyarylethernitrile particles from the discharge port 64, the lower side of the inner wall of the discharge port 64 can be set to be inclined downward.
[0023] Reference Figure 2 and Figure 5 The filter assembly 10 includes a sealing plate 101 disposed on the side wall of the body 1, and a U-shaped plate 102 is disposed on the side wall of the sealing plate 101, which is inserted into the body 1 and placed below the stirring assembly 6, and a filter screen 103 for filtering the polyarylethernitrile particles is disposed inside the U-shaped plate 102. This design improves the sealing of the connection through the sealing plate 101, and facilitates the filtering and supporting of the polyarylethernitrile particles through the filter screen 103 and the U-shaped plate 102. In order to avoid friction between the filter screen 103 and the polyarylethernitrile particles, which may cause a decrease in the quality of the polyarylethernitrile particles, a coating such as silica gel may be sprayed on the mesh surface of the filter screen 103.
[0024] Reference Figure 2 and Figure 4 The side wall of the machine body 1 is provided with a sealing groove 1001 matching with the sealing plate 101, and the inside of the machine body 1 is provided with a guide groove 1002 communicating with the sealing groove 1001 and matching with the U-shaped plate 102, and the vertical cross-sectional area of the guide groove 1002 is smaller than the vertical cross-sectional area of the sealing groove 1001. This design facilitates the connection and placement of the sealing plate 101 and the U-shaped plate 102, wherein the inner wall of the U-shaped sealing plate 101 and the inner wall of the machine body 1 are on the same vertical plane, so that the polyarylethernitrile particles fall completely on the filter screen 103.

This design uses the guide scraper 16. When the sealing plate 101 drives the filter screen 103 on the U-shaped plate 102 to move longitudinally, the polyarylethernitrile particles are scraped off the surface of the filter screen 103 from the through groove 104 under the action of the guide scraper 16. At the same time, when the filter screen 103 on the U-shaped sealing plate 101 leaves the position supporting the polyarylethernitrile particles, the unloading chute 1003 is connected to the guide groove 1002 and is tilted downward, thereby preventing the polyarylethernitrile particles from remaining inside the guide groove 1002.
[0026] Reference Figure 5 , Figure 6 and Fig.10 , the guide plate 11 includes a square plate 161 embedded in the inner wall of the body 1, and a triangular plate 162 extends from the side wall of the square plate 161; The triangular plate 162 is a right-angled triangular plate, and the right-angled side of the triangular plate 162 is flush with the inner wall of the body 1. This design facilitates the scraping of the polyarylethernitrile particles on the filter screen 103 through the triangular plate 162, and also plays a role in diversion.
[0027] Reference Figure 4 , Figure 5 , Figure 7 and Figure 8 , and also includes a pair of driving components 7 symmetrically arranged inside the body 1 and used to push the sealing plate 101 to move longitudinally. The driving component 7 includes a driving motor 71 arranged on the side wall of the body 1. A guide column 74 inserted into the body 1 is arranged at a position corresponding to the driving motor 71 on the sealing plate 101. A threaded hole 73 is provided inside the guide column 74. A screw rod 72 located inside the threaded hole 73 is provided on the output shaft of the driving motor 71. A guide hole 75 matching the guide column 74 is provided inside the body 1.

The movement of the guide column 74 pushes the sealing plate 101 to move, and the movement of the sealing plate 101 drives the movement of the U-shaped plate 102.

This design facilitates the liquid in the water inlet pipe 2 to flow in and out from the plurality of liquid dispersion holes 122 through the hollow groove 121, and the liquid can be evenly distributed inside the machine body 1, and cooperate with the polyarylether nitrile particles evenly distributed through the stirring assembly 6, thereby improving the efficiency of stirring, cleaning and removing impurities from the polyarylether nitrile particles; the water inlet valve 2 can adjust the flow rate of the water inlet pipe 2 and close the water inlet, which can prevent the liquid from moving upward along the feed pipe 5 when the water inlet flow rate is large; the sealing of the connection is improved through the sealing bearing 123.
[0029] Reference Figure 3 and Fig. 9 The side wall of the feed pipe 5 is provided with a plurality of water inlet grooves 14 placed inside the hollow groove 121, and the side wall of the feed pipe 5 is provided with a shielding net 15 for shielding the water inlet grooves 14, and a mounting bearing 13 is provided at the connection between the guide pipe 4 and the feed pipe 5. This design allows liquid to enter the feed pipe 5 through the water inlet grooves 14, so that the polyarylethernitrile particles inside the feed pipe 5 are completely discharged from the discharge port 64 along with the liquid, and the shielding net 15 is used to shield the polyarylethernitrile particles to prevent the polyarylethernitrile particles from entering the hollow groove 121 of the dispersion plate 12.
[0030] Reference Figure 1 and Figure 2 A sampling tube 8 located below the filter assembly 10 is disposed on the side wall of the body 1, and a sampling valve 81 is disposed on the side wall of the sampling tube 8. The design allows sampling according to demand through the sampling tube 8 and the sampling valve 81, and takes out part of the liquid to detect inorganic impurities such as potassium sulfide and potassium carbonate in the liquid. When the test is qualified, the liquid is discharged first, and then the filter assembly 10 is driven by the driving assembly 7 to lose the filtering shielding of the polyarylethernitrile particles, so that the polyarylethernitrile particles are discharged from the discharge pipe 9. When the test is unqualified, the discharge valve 91 is opened to allow the liquid to flow out of the discharge pipe 9 and the liquid is replaced again for continued water washing.
[0031] Reference Figure 1-Figure 10As an embodiment of the present invention: when it is necessary to pelletize and remove impurities from the polyarylethernitrile, the staff pelletizes the polyarylethernitrile by using the shear pump 3, and the polyarylethernitrile particles enter the inside of the discharge pipe 5 from the outlet end of the shear pump 3 along the guide pipe 4, and then the stirring motor 61 in the stirring assembly 6 is operated to drive the first gear 62 to rotate, the first gear 62 rotates to drive the second gear 63 to rotate, the second gear 63 rotates to drive the discharge pipe 5 to rotate, the discharge pipe 5 rotates to drive the stirring column 65 to rotate, the polyarylethernitrile particles flowing into the discharge pipe 5 from the guide pipe 4 are discharged from the discharge port 64 on the side wall of the discharge pipe 5, and the polyarylethernitrile particles flowing out of the discharge port 64 are knocked and stirred under the action of the stirring column 65, so that the polyarylethernitrile particles are evenly dispersed inside the machine body 1. The polyarylether nitrile particles are distributed on the filter screen 103 of the filter assembly 10 for support, and at the same time, the liquid is sent to the inside of the bulk liquid plate 12 through the water inlet pipe 2, and the flow rate of the liquid is adjusted by adjusting the water inlet valve 21 to prevent the liquid from being discharged from the top of the discharge pipe 5 along the water inlet trough 14. A small amount of liquid enters the water inlet trough 14 and flows into the inside of the discharge pipe 5 and drives the polyarylether nitrile particles in the discharge pipe 5 to be discharged from the discharge port 64, so as to prevent the polyarylether nitrile particles from remaining in the discharge pipe 5. The polyarylethernitrile particles in the free discharge pipe 5 enter the hollow groove 121, and most of the liquid enters the hollow groove 121. Under the action of the multiple liquid dispersion holes 122 at the bottom of the liquid dispersion plate 12, the liquid is evenly distributed to the inside of the body 1, and is contacted and rinsed with the evenly dispersed polyarylethernitrile particles. The stirring column 65 rotates to stir the liquid and polyarylethernitrile particles flowing into the body 1, and the impurity inorganic salts wrapped in the polyarylethernitrile particles can be effectively stirred and washed out, thereby improving the yield. Since impurity inorganic salts such as potassium sulfide and potassium carbonate can be dissolved in an aqueous solution, the discharge valve 91 is opened so that the impurities are washed out with the liquid and then flow out of the discharge pipe 9, which is convenient for cleaning the impurities.
[0032] When the liquid is discharged, the driving motor 71 in the driving assembly 7 starts to work and drives the screw rod 72 to rotate. The screw rod 72 rotates and drives the guide column 74 to move along the guide hole 75 inside the body 1 under the action of the internal threaded hole 73 of the guide column 74. The guide column 74 moves to push the sealing plate 101 to move along the sealing groove 1001 to the side away from the body 1. The movement of the sealing plate 101 drives the U-shaped plate 102 to move along the guide groove 1002, and drives the filter screen 103 thereon to move to the side away from the body 1. Under the action of the guide scraper 16, the polyaromatic The ether nitrile particles are scraped off the surface of the filter screen 103 from the through groove 104. At the same time, when the filter screen 103 on the U-shaped sealing plate 101 leaves the position supporting the polyarylether nitrile particles, the discharge chute 1003 is connected with the guide groove 1002 and is tilted downward, thereby preventing the polyarylether nitrile particles from remaining in the guide groove 1002. The polyarylether nitrile particles enter the discharge pipe 9 along the inner wall of the body 1 under the guidance of the guide plate 11 and are discharged. When the polyarylether nitrile particles are discharged, a vibration motor can be set on the body 1 as needed to speed up the outflow speed of the material.
