Description

Technical Field

[0001] The utility model relates to the technical field of polyether ester granulation, in particular to a rapid dispersion granulation device for the production of thermoplastic polyether ester elastomers. Background Art

[0002] The polyether ester granulation technology has been widely used in the plastic and chemical industries. Especially in the production process of polymer materials, as an important polymer material, polyether ester usually needs to be cooled by water after being extruded through an extruder to ensure the appropriate hardness and shape of the material. The extruded strip-shaped polyether ester is cut into particles for subsequent processing and application. In the granulation process of existing polyether ester granulation equipment, due to the residual moisture on the surface of the particles, improving the granulation process to reduce moisture residue has become an important development direction in the industry.

[0003] General polyether ester granulation equipment still faces some challenges in practical applications. After the granulated polyether ester particles are cooled by water, there will be residual moisture, resulting in the granulated polyether ester particles being prone to agglomeration, which not only reduces the quality of the polyether ester particles, but also may cause the particles to mildew easily during transportation, and also affects the consistency and fluidity of the particles, increasing the difficulty of subsequent processing. Particles with too high humidity are prone to mildew during storage, further reducing the quality of the material and affecting the stability and service performance of the product, and cannot meet the actual requirements. Summary of the Utility Model

Particles with too high humidity are prone to mildew during storage, further reducing the quality of the material.

[0019] A rapid dispersion granulation device for the production of thermoplastic polyether ester elastomers disclosed by the present utility model is mainly applied to the scenario where general polyether ester granulation devices still face some challenges in actual applications. After water-cooling treatment, the granulated polyether ester particles will have residual moisture, resulting in the granulated polyether ester particles being prone to agglomeration, which not only reduces the quality of the polyether ester particles, but also may cause the particles to easily grow mold during transportation, and also affects the consistency and fluidity of the particles, increasing the difficulty of subsequent processing. The particles with too high humidity are prone to growing mold during storage, further reducing the material quality.

[0020] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a rapid dispersion granulation device for the production of thermoplastic polyether ester elastomers, comprising a housing 1, a top shell 4 is provided at the top of the housing 1, an inner shell 17 is provided inside the top shell 4, a plurality of air outlets 3 are respectively provided on one side of the housing 1, an air pump 6 and a conduit 5 are provided on the other side of the housing 1, a mounting frame 10 is fixedly connected to the top edge of the housing 1, a motor 9 is provided on one side of the mounting frame 10, an upper rotating pipe 12 and a lower rotating pipe 13 are respectively provided inside the top shell 4, a driven cylinder 23 and a driving cylinder 22 are respectively provided at one ends of the upper rotating pipe 12 and the lower rotating pipe 13, a plurality of cutting plates 20 are provided on the outer surface of the driving cylinder 22, a plurality of card slots 24 are provided on the outer surface of the driven cylinder 23, a plurality of air spray holes 21 are provided on the outer surfaces of the upper rotating pipe 12 and the lower rotating pipe 13, a plurality of air guide holes 19 are provided on the outer surfaces of the driven cylinder 23 and the driving cylinder 22, and a feed inlet 18 is provided on one side of the top shell 4.

[0021] Furthermore, a second pulley 11 is provided at one end of the output shaft of the motor 9, and a protective frame 14 is provided at the top of the housing 1.

[0022] In this embodiment, an operator pulls a plurality of strip-shaped polyether esters to the feed inlet 18 and inserts them into the inside of the top shell 4, inserts the strip-shaped polyether esters between the driving cylinder 22 and the driven cylinder 23. The driving cylinder 22 and the driven cylinder 23 are inside the inner shell 17. Subsequently, the motor 9 is started to drive the lower rotating pipe 13 and the driving cylinder 22 to rotate. During the rotation of the driving cylinder 22, a plurality of cutting plates 20 on its surface are sequentially stuck inside a plurality of card slots 24 on the outer surface of the driven cylinder 23, so that the driving cylinder 22 and the driven cylinder 23 rotate relatively, driving a plurality of strip-shaped polyether esters to continuously enter the inside of the inner shell 17.

[0023] Among them, it is worth noting that a conveying roller (not shown in the figure) can be provided at the position of the feed inlet 18 for conveying strip-shaped polyether esters in the direction of the driving cylinder 22 and the driven cylinder 23.

[0024] Furthermore, the cutting plates 20 and the card slots 24 cooperate to cut the strip-shaped polyether esters into particles of the same length. Since there is residual moisture on the surface of the strip-shaped polyether esters after being cooled by water, the air pump 6 is started to exhaust air into the inside of the conduit 5, and the air enters the inside of the driven cylinder 23 and the driving cylinder 22 respectively through the upper rotating pipe 12 and the lower rotating pipe 13, and is sprayed out through a plurality of air guide holes 19 on the surfaces of the driven cylinder 23 and the driving cylinder 22 to form an air flow, separating the polyether ester particles from the driving cylinder 22 and the driven cylinder 23, achieving the effect of preventing the polyether ester particles from adhering to the surfaces of the driving cylinder 22 and the driven cylinder 23.

[0025] Refer to Figure 1 、Figure 2 and Figure 3 In a preferred embodiment, a stirring wheel 15 is provided inside the outer shell 1, a friction cylinder 16 is provided inside the outer shell 1, a plurality of air outlet holes are provided on the outer surface of the friction cylinder 16, a first belt pulley 7 is provided at one end of the stirring wheel 15, and a belt 8 is provided between the first belt pulley 7 and the second belt pulley 11.

[0026] In this embodiment, when the polyether ester particles enter the inside of the friction cylinder 16 through the inner shell 17, a large amount of air is discharged from the outer shell 1 through the plurality of air outlet holes and the air outlet 3 on the outer surface of the friction cylinder 16. The accelerated air flow inside dehumidifies the polyether ester particles and takes away the moisture on the surface of the polyether ester particles. At the same time, the motor 9 drives the second belt pulley 11 and the first belt pulley 7 to rotate, thereby driving the stirring wheel 15 to rotate inside the friction cylinder 16, stirring the polyether ester particles inside the friction cylinder 16, improving the air-drying efficiency, and also preventing the polyether ester particles from agglomerating and caking. The processed polyether ester particles are discharged through the discharge box 2.

[0027] Working principle: During use, manually pull multiple strip-shaped polyether esters and insert them into the inside of the top shell 4 from the feed port 18, and insert the strip-shaped polyether esters between the driving cylinder 22 and the driven cylinder 23. The driving cylinder 22 and the driven cylinder 23 are inside the inner shell 17. Start the motor 9 to drive the rotating tube 13 and the driving cylinder 22 to rotate. During the rotation of the driving cylinder 22, the plurality of cutting plates 20 on its surface are sequentially stuck inside the plurality of card slots 24 on the outer surface of the driven cylinder 23, so that the driving cylinder 22 and the driven cylinder 23 rotate relative to each other, driving the multiple strip-shaped polyether esters to continuously enter the inside of the inner shell 17. The cutting plates 20 and the card slots 24 cooperate to cut the strip-shaped polyether esters into particles of the same length. Since the surface of the strip-shaped polyether ester remains moist after water-cooled heat dissipation, start the air pump 6 to exhaust air into the conduit 5, and the air enters the inside of the driven cylinder 23 and the driving cylinder 22 through the upper rotating tube 12 and the lower rotating tube 13 respectively, and is ejected through the plurality of air guide holes 19 on the surfaces of the driven cylinder 23 and the driving cylinder 22 to form an air flow, separating the polyether ester particles from the driving cylinder 22 and the driven cylinder 23, achieving the effect of preventing the polyether ester particles from adhering to the surfaces of the driving cylinder 22 and the driven cylinder 23. When the polyether ester particles enter the inside of the friction cylinder 16 through the inner shell 17, a large amount of air is discharged from the outer shell 1 through the plurality of air outlet holes and the air outlet 3 on the outer surface of the friction cylinder 16. The accelerated air flow inside dehumidifies the polyether ester particles and takes away the moisture on the surface of the polyether ester particles. At the same time, the motor 9 drives the second belt pulley 11 and the first belt pulley 7 to rotate, thereby driving the stirring wheel 15 to rotate inside the friction cylinder 16, stirring the polyether ester particles inside the friction cylinder 16, improving the air-drying efficiency, and also preventing the polyether ester particles from agglomerating and caking.
