Description

Technical Field

[0001] This utility model relates to the field of polyamide production grading and conveying equipment, and in particular to a high-efficiency and stable polyamide production grading and conveying device. Background Technology

[0002] In the production and processing of polyamide, graded conveying is one of the most crucial steps. Its core purpose is to accurately separate polyamide materials based on their physical properties such as particle size and density, so as to provide raw materials that meet quality requirements for subsequent molding and processing processes, which directly affects the performance and quality of the final product.

[0003] Existing grading and conveying devices for polyamide materials are mostly traditional screening and conveying devices. These devices typically use filter plates as the core filtration component and achieve grading through the material's own gravity or simple mechanical vibration. In application, this type of device has many technical defects. The vibration frequency and amplitude of traditional devices are difficult to control, making it impossible to effectively deal with material blockage. Furthermore, traditional air blowing equipment is mostly fixed and cannot be adjusted according to the actual distribution of the material on the filter plate, resulting in low transmission efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a high-efficiency and stable polyamide production grading and conveying device, comprising a protective shell 1 for protecting the internal structure of the equipment. A feed inlet 2 is fixedly connected to the top right side of the protective shell 1, providing material entry into the equipment space. Two sets of switch doors 4 are provided on the front and rear sides of the outer wall of the protective shell 1. The switch doors 4 assist the protective shell 1 in protecting the internal structure of the equipment and facilitate adjustment of internal components by the operator. Multiple sets of support rods 8 are fixedly connected to the inner wall of the protective shell 1, supporting filter plates 5. Filter plates 5 are slidably connected to the outer sides of the multiple sets of support rods 8. The filter holes on the inner walls of the multiple sets of filter plates 5 are of different sizes. A discharge port 3 is fixedly connected to the left side of the filter plate 5 for collecting the classified material. An adjustment component 6 is fixedly connected to the top of the filter plate 5 to accelerate material filtration efficiency. A vibration component 7 is rotatably connected through the inner wall of the protective shell 1 to vibrate the filter plate 5 and prevent material from clogging the filter holes.

[0031] Reference Figure 1 - Figure 3The adjusting component 6 includes a support block 69, which supports the fixing rod 61. The bottom of the support block 69 is fixedly connected to the top of the filter plate 5. The fixing rod 61 is rotatably connected through the inner wall of the support block 69. The fixing rod 61 supports the sleeve 63. Nuts 62 are threaded to both ends of the fixing rod 61. The nuts 62 are used to rotate and adjust the fixing rod 61. Multiple sets of limiting holes 64 are opened on the outer wall of the fixing rod 61. The limiting holes 64 are used to limit the sleeve 63. Multiple sets of sleeves 63 are slidably connected to the outer wall of the fixing rod 61. The sleeves 63 are used to adjust the spacing of the air tubes 66 and adapt to... The material distribution in different areas of the filter plate 5 improves the flexibility of adjustment. Multiple sets of sleeves 63 are connected to the limiting holes 64 by limiting rods 65. The limiting rods 65 are used to connect the sleeves 63 and the limiting holes 64. Each set of sleeves 63 is fixedly connected to an air pipe 66, which is used to support the nozzle 68. Connectors 67 are fixedly connected between the air pipes 66. The connectors 67 are corrugated pipes. The nozzle 68 is fixedly connected to the left side of the air pipe 66. The nozzle 68 is a pneumatic nozzle. The nozzle 68 blows air to disperse the material accumulated on the filter plate 5, reducing filtration obstruction and thus accelerating the filtration efficiency.

[0032] Reference Figure 2 - Figure 4 The vibration assembly 7 includes a motor 71, which drives a rotating rod 72 to rotate. The motor 71 is fixedly connected to the outer wall of the protective shell 1. The output shaft of the motor 71 is fixedly connected to the rotating rod 72, which supports a disc 73. Two sets of discs 73 are fixedly connected to the outer wall of the rotating rod 72. When the discs 73 rotate, they drive the adjusting block 74 to rotate. An adjusting block 74 is rotatably connected to one side of the two sets of discs 73. The adjusting block 74 is triangular, and its outer surface is arc-shaped. The rotation point of the adjusting block 74 and the disc 73 is far away from the adjusting block 74. At the center, when the adjusting block 74 rotates, the outer arc of the wall periodically impacts the fixed block 77, causing the filter plate 5 to slide along the support rod 8 and generate vibration. The inner wall of the adjusting block 74 has a through sliding groove 76, which provides space for the fixed bolt 75 to move. The fixed bolt 75 is slidably connected to the inner wall of the sliding groove 76. The fixed bolt 75 is used to fix the rotation amplitude of the adjusting block 74. The fixed bolt 75 is fixedly connected to the disc 73. Fixed blocks 77 are fixedly connected to the left and right sides of the filter plate 5. The fixed blocks 77 are used to receive the power of the adjusting block 74 and drive the filter plate 5 to vibrate.

[0033] Working principle: When using this polyamide production grading and conveying device, the polyamide material is fed into the protective shell 1 through the feed port 2. After the material falls onto the filter plate 5, the motor 71 is started. The motor 71 drives the rotating rod 72 to rotate, and the rotating rod 72 drives the two sets of discs 73 to rotate synchronously. When the discs 73 rotate, they drive the adjusting block 74 to rotate. The adjusting block 74 maintains a stable rotation amplitude through the cooperation of the inner wall sliding groove 76 and the fixing bolt 75 on the disc 73. Its arc-shaped outer surface periodically hits the fixing blocks 77 on the left and right sides of the filter plate 5, causing the filter plate 5 to slide along the support rod 8 and generate vibration, thus preventing the material from clogging the filter holes.

[0034] When the nozzle 68 needs adjustment, open the switch doors 4 on the front and rear sides of the outer wall of the protective shell 1. First, loosen the nuts 62 at both ends of the fixing rod 61 to release the limit on the fixing rod 61. Adjust the distance between the sleeves 63 according to the material distribution in different areas of the filter plate 5. After the position is determined, insert the limiting rod 65 into the limiting hole 64 on the outer wall of the sleeve 63 and the fixing rod 61 to complete the fixing of the sleeve 63. The air pipe 66 at the bottom of the sleeve 63 is kept connected through the connector 67. The nozzle 68 blows air onto the filter plate 5 to disperse the material accumulated on the filter plate 5 and reduce filtration obstruction. Under the action of vibration and air blowing, the material is filtered in stages through the filter plates 5 with different filter hole sizes. The graded material is finally collected from the discharge port 3 on the left side of the filter plate 5.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
