DETAILED DESCRIPTION
[0021] In order to make the technical solution of the present invention easier to understand, the technical solution of the present invention is now clearly and completely described in conjunction with the accompanying drawings using specific embodiments.
[0022] Example 1:
[0023] like Figure 1-5 As shown, the embodiment of the present invention Figure 1-5 The utility model is a device for separating metal particles from polyethylene products, comprising a pellet product bin 1, wherein:
[0024] The granular product bin 1 is provided with a granular transport crawler 2, the other end of the granular transport crawler 2 is connected to a washing machine 3, a washing product output pipe 4 is provided at the bottom of the washing machine 3, one end of the washing product output pipe 4 is connected to the product transport crawler 5, one end of the product transport crawler 5 is provided with a discharge plate, the discharge plate is connected to a rotary discharge valve 6, one end of the rotary discharge valve 6 is provided with a discharge pipe 7, the other end of the discharge pipe 7 is connected to a metal adsorption device 8, the bottom of the metal adsorption device 8 is connected to a discharge conveying pipe 9, and the discharge conveying pipe 9 is connected to a finished product packaging bin 10.
[0025] The metal adsorption device 8 includes a shell 81, a flange connection port 82 is installed at the top opening of the shell 81, drawer openings 83 are respectively opened on the two adjacent side walls of the shell 81, and a metal adsorption drawer 84 is installed in the drawer opening 83. The inner wall of the shell 81 is provided with a fixed slot 85, and a plurality of limit rings 86 are installed on the shell 81. The plurality of limit rings 86 are respectively detachably contacted and fitted with the limit openings 842 on both sides of the metal adsorption drawer 84, and the collection port 89 at the bottom of the shell 81 is detachably connected to the discharge conveying pipe 9.
[0026] The metal adsorption drawer 84 includes a drawer baffle 841, and limit openings 842 are provided on both sides of the drawer baffle 841. A number of threaded openings 843 are provided on the drawer baffle 841. A metal shell 844 is fixedly mounted on one side of the threaded opening 843. One end of the metal shell 844 is inserted into the fixed slot 85. One end of the magnetic rod 845 is sleeved inside the metal shell 844. The end of the magnetic rod 845 located outside the metal shell 844 is provided with a magnetic rod handle 846. A connecting thread is provided at the connection between the magnetic rod handle 846 and the magnetic rod 845, and the connecting thread and the threaded opening 843 are detachable and assembled.
[0027] One side of the limiting ring 86 is movably connected to the fixing block 87 .
[0028] A spray connection hole 88 is provided on one side of the shell 81 , a movable baffle is provided on the spray connection hole 88 , and a collecting port 89 is provided at the bottom of the shell 81 .
[0029] The flange connection port 82 is detachably equipped with a bellows.
[0030] A drawer handle 847 is provided on the outer side of the drawer baffle 841 .
[0031] A plurality of the metal adsorption drawers 84 are installed in the metal adsorption drawer 84 in a staggered manner horizontally and vertically.
[0032] During the use of this device, when the product enters the washing machine 3 from the granular product bin 1 for washing, it is transported to the metal adsorption device 8 through the product transport track 5. When the product with metal particles enters the metal adsorption device 8, the magnetic rod 845 in the metal shell 844 provides magnetic adsorption, and the product is adsorbed layer by layer through the metal adsorption drawer 84. Finally, the cleanly adsorbed product enters the discharge conveying pipe 9 from the collection port 89 and enters the finished product packaging bin 10.
[0033] During the production process, the magnetic rod 845 in the metal adsorption drawer 84 can be adjusted according to production needs. When strong adsorption is required, all the magnetic rods 845 in the metal shell 844 can be installed. When strong adsorption is not required, the magnetic rod 845 can be selectively disassembled. Before use, confirm that one end of the metal shell 844 is inserted into the fixed slot 85, and then buckle the limiting ring 86 into the limiting opening 842 to start use. When production is completed and cleaning is required, it is only necessary to replace the discharge conveying pipe 9 equipped on the collection port 89 with the collection pipe. The pipe and the collection bag are connected, and then the magnetic rod 845 in the metal shell 844 is removed. At this time, the suction force generated by the magnetic rod 845 on the metal shell 844 disappears, and the metal particles adsorbed on the metal shell 844 automatically fall to the bottom. In order to clean it, the movable baffle on the blowing connection hole 88 is opened, and the blowing equipment is connected to the blowing connection hole 88 for blowing cleaning. The cleaned waste enters the collection bag through the collection port 89; this device reduces the space gap inside the metal adsorption device 8 by staggered arrangement of metal adsorption drawers 84, which can enhance the adsorption capacity.
[0034] This device effectively removes metal particles, reducing the risk of contamination during the production process, thereby improving the overall quality of the final product and meeting higher quality control standards.
[0035] It should be noted that the embodiments described herein are only some embodiments of the present invention, not all implementations of the present invention. The embodiments are merely illustrative and serve only to provide a more intuitive and clear way to understand the content of the present invention, rather than to limit the technical solutions described in the present invention. Without departing from the concept of the present invention, all other implementation methods that can be thought of by ordinary technicians in this field without creative work, as well as other simple replacements and various variations of the technical solutions of the present invention, are within the scope of protection of the present invention.
