Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyphenylene sulfide preparation technology, and in particular to a granulation device for polyphenylene sulfide. Background Technology
[0002] Polyphenylene sulfide (PPS) is resistant to high temperatures, solvents, acid and alkali corrosion, radiation, and flame, and possesses balanced mechanical and electrical properties. It is considered one of the key materials necessary for the development of high technology. PPS porous membranes can trap suspended particles, dust, bacteria, and fungi in air and liquids, and have wide application value in reverse osmosis, dialysis, ultrafiltration, and gas separation. The material can be used for a long time in acidic, alkaline, or organic solvents at high temperatures. Therefore, PPS materials have a wide range of applications in the field of membrane technology.
[0003] During production, polyphenylene sulfide (PPS) is mostly produced in the form of long strips or irregular blocks from the preparation equipment. PPS in this shape cannot be used directly and needs to be shredded into granules before use. However, the granulation equipment in the existing technology directly cuts PPS, which cannot guarantee the size and shape of the PPS granules. This will lead to a decrease in the quality of the PPS granules and fail to achieve the desired effect.
[0004] To address the aforementioned issues, we propose a granulation apparatus for polyphenylene sulfide. Summary of the Invention
[0005] The purpose of this invention is to provide a granulation device for polyphenylene sulfide (PPS), which solves the problem that existing granulation devices directly cut PPS, making it impossible to guarantee the size and shape of PPS particles, thus leading to a decrease in the quality of PPS particles and failing to achieve the desired effect.
[0006] To achieve the above objectives, this utility model employs a granulation device for polyphenylene sulfide, comprising a pulverizing extrusion molding assembly. The pulverizing extrusion molding assembly includes a pulverizing chamber, a semi-open cover, a drive motor, and a pulverizing roller. The semi-open cover is detachably connected to the pulverizing chamber and is located above the pulverizing chamber. The drive motor is detachably connected to the semi-open cover and is located at the center above the semi-open cover. The drive motor is also positioned at the center above the pulverizing chamber. The pulverizing roller passes through the semi-open cover and is detachably connected to the drive motor, located at the output end of the drive motor. The pulverizing roller is disposed inside the pulverizing chamber.
[0007] The pulverizing extrusion molding assembly further includes a separating screen plate, which is fixedly connected to the pulverizing box and located at the center of the pulverizing box. The separating screen plate is disposed below the pulverizing roller and is also perpendicular to the pulverizing roller.
[0008] The crushing extrusion molding assembly further includes a support frame and a conveyor belt. One end of the support frame is located inside the crushing chamber and below the separating screen plate. The other end of the support frame is located on the outside of the crushing chamber. The conveyor belt is located above the support frame and below the separating screen plate.
[0009] The crushing extrusion molding assembly further includes a guide block, which is fixedly connected to the crushing box and located inside the crushing box. The guide block is positioned below the separating screen plate and above the conveyor belt.
[0010] The crushing extrusion molding assembly further includes a mounting frame and an extrusion molding machine. The mounting frame is located on one side of the support frame and on the side of the crushing box near the support frame. One side of the extrusion molding machine is detachably connected to the mounting frame and is located on the side of the mounting frame near the conveyor belt. The other side of the extrusion molding machine is located above the conveyor belt.
[0011] The crushing and extrusion molding assembly further includes a sieve inclined plate and a residue collection box. The sieve inclined plate is detachably connected to the support frame and is located below the support frame on the side away from the crushing box. The residue collection box is located on the side of the support frame away from the crushing box and is located below the sieve inclined plate.
[0012] This utility model discloses a granulation device for polyphenylene sulfide (PPS), comprising a pulverizing extrusion molding assembly. The pulverizing extrusion molding assembly includes a pulverizing chamber, a semi-open cover, a drive motor, and a pulverizing roller. The semi-open cover is detachably connected to the pulverizing chamber and located above it. The drive motor is detachably connected to the semi-open cover and located at the center above it, and is also positioned at the center above the pulverizing chamber. The pulverizing roller passes through the semi-open cover and is detachably connected to the drive motor, located at the output end of the drive motor, and is disposed inside the pulverizing chamber. By modifying and replacing the original structure with a pulverizing extrusion molding assembly, this effectively solves the problem that existing granulation devices directly cut PPS, failing to guarantee the size and shape of PPS particles, thus leading to a decrease in the quality of PPS particles and preventing the achievement of ideal performance.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0019] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a top view of the entire utility model. Figure 3 This is a utility model Figure 2 A cross-sectional view of the AA line structure.
[0020] This utility model provides a granulation device for polyphenylene sulfide (PPS), including a crushing and extrusion molding assembly. The crushing and extrusion molding assembly includes a crushing box 101, a semi-open cover 102, a drive motor 103, a crushing roller 104, a separating screen plate 105, a support frame 106, a conveyor belt 107, a guide block 108, a mounting frame 109, an extrusion molding machine 110, a sieve inclined plate 111, and a residue collection box 112. This solution addresses the problem that existing granulation devices directly cut PPS, failing to guarantee the quality of PPS granules. The size and shape of polyphenylene sulfide (PPS) particles can lead to a decrease in quality and prevent them from achieving the desired performance. Understandably, the aforementioned solution addresses this by conveying the long or irregularly shaped PPS particles through the semi-open cap 102 into the crushing chamber 101 when granulation is required. Then, the drive motor 103 is activated, driving the crushing roller 104 to effectively crush the long or irregularly shaped PPS particles. After the polyphenylene sulfide (PPS) reaches a size that allows passage through the separating screen plate 105, it is conveyed above the conveyor belt 107 below the separating screen plate 105. The conveyor belt 107 transports the pulverized PPS to the extrusion molding machine 110, where the extrusion molding machine 110 extrudes and molds the pulverized PPS to form uniformly shaped PPS granules. The extrusion residue is then conveyed along with the PPS granules to the sieve inclined plate 111, where the sieve inclined plate 111... 1. This effectively separates polyphenylene sulfide (PPS) particles from residues. The residues are collected by the residue collection box 112 for reuse. Since the crushing box 101 is cylindrical, the guide block 108 prevents residual crushed PPS from remaining on the conveyor belt 107 in the interlayer or gaps. This effectively solves the problem that existing granulation devices directly cut PPS, which cannot guarantee the size and shape of PPS particles, leading to a decrease in the quality of PPS particles and failure to achieve the desired effect.
[0021] In this specific embodiment, the semi-open cover is detachably connected to the crushing chamber 101 and is located above the crushing chamber 101. The drive motor 103 is detachably connected to the semi-open cover and is located at the center above the semi-open cover. The drive motor 103 is also located at the center above the crushing chamber 101. The crushing roller 104 passes through the semi-open cover 102 and is detachably connected to the drive motor 103, and is located at the output end of the drive motor 103. The crushing roller 104 is located inside the crushing chamber 101. When it is necessary to granulate long strips or irregular blocks of polyphenylene sulfide, the long strips or irregular blocks of polyphenylene sulfide are conveyed into the crushing chamber 101 through the semi-open cover 102. Then, the drive motor 103 is started, and the drive motor 103 drives the crushing roller 104 to effectively crush the long strips and irregular blocks of polyphenylene sulfide.
[0022] The separating screen plate 105 is fixedly connected to the crushing box 101 and located at the internal center of the crushing box 101. The separating screen plate 105 is disposed below the crushing roller 104 and is also perpendicular to the crushing roller 104. After the crushed polyphenylene sulfide reaches a size that can be passed through the separating screen plate 105, it will be conveyed into the conveyor belt 107 above the separating screen plate 105.
[0023] Secondly, one end of the support frame 106 is located inside the crushing box 101, and another end of the support frame 106 is located below the separating screen plate 105. The other end of the support frame 106 is located on the outside side of the crushing box 101. The conveyor belt 107 is located above the support frame 106 and below the separating screen plate 105.
[0024] Meanwhile, the guide block 108 is fixedly connected to the crushing box 101 and located inside the crushing box 101. The guide block 108 is located below the separating screen plate 105 and above the conveyor belt 107. Since the crushing box 101 is cylindrical, the guide block 108 will prevent the conveyor belt 107 from leaving crushed polyphenylene sulfide in the interlayer or gaps.
[0025] Additionally, the mounting frame 109 is located on one side of the support frame 106, and the mounting frame 109 is located on the side of the crushing box 101 near the support frame 106. One side of the extrusion molding machine 110 is detachably connected to the mounting frame 109 and is located on the side of the mounting frame 109 near the conveyor belt 107. The other side of the extrusion molding machine 110 is located above the conveyor belt 107. The conveyor belt 107 transports the crushed polyphenylene sulfide to the extrusion molding machine 110, where the extrusion molding machine 110 extrudes and molds the crushed polyphenylene sulfide, thereby forming polyphenylene sulfide particles with uniform shape.
[0026] The sieve inclined plate 111 is detachably connected to the support frame 106 and is located below the support frame 106 on the side away from the crushing box 101. The residue collection box 112 is located on the side of the support frame 106 away from the crushing box 101 and is located below the sieve inclined plate 111. The extruded residue will be transported to the sieve inclined plate 111 along with the polyphenylene sulfide particles. Thus, the sieve inclined plate 111 will effectively separate the polyphenylene sulfide particles from the residue, and the residue will be collected by the residue collection box 112 for reuse.
[0027] When using this invention to granulate long strips or irregular blocks of polyphenylene sulfide (PPS), the PPS is conveyed into the crushing chamber 101 through the semi-open cap 102. Then, the drive motor 103 is started, driving the crushing roller 104 to effectively crush the PPS. Once the crushed PPS reaches a size that can pass through the separating screen plate 105, it is conveyed above the conveyor belt 107 below the separating screen plate 105. The conveyor belt 107 then transports the crushed PPS to the extrusion molding machine 110, where it is processed. The ether is extruded to form polyphenylene sulfide (PPS) granules with uniform shapes. The extrusion residue is conveyed along with the PPS granules to the sieve inclined plate 111, which effectively separates the PPS granules from the residue. The residue is collected by the residue collection box 112 for reuse. Since the crushing box 101 is cylindrical, the guide block 108 prevents the conveyor belt 107 from leaving crushed PPS sulfide in the interlayer or gaps. This effectively solves the problem that existing granulation devices directly cut PPS sulfide, which cannot guarantee the size and shape of the PPS granules, resulting in a decrease in the quality of the PPS granules and failure to achieve the desired effect.
[0028] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
