[0032] See appendix Figure 1-3As shown in the figure, an embodiment of the present invention discloses a polyethylene wax melting centrifugal separation device, including a workbench 100. A support plate 101 is fixedly installed on the top of one side of the workbench 100. A protective cylinder 110 is connected to one side of the support plate 101 via a rotating assembly. The bottom of the protective cylinder 110 rotates downward and passes through the workbench 100. A fixing ring 112 is fixedly connected to the opening of the protective cylinder 110. A processing cylinder 108 is fixedly inserted into the inner cavity of the fixing ring 112. The processing cylinder 108 is provided with a stirring device for stirring the polyethylene wax inside the cylinder. The processing cylinder 108 has its opening facing downwards. The opening of the processing cylinder 108 extends downwards through the protective cylinder 110 and is connected to a cylinder cover 111 via a detachable assembly. A heating assembly for melting the polyethylene wax inside the processing cylinder 108 is provided between the protective cylinder 110 and the processing cylinder 108. A centrifugal assembly for rotating the protective cylinder 110 to centrifuge the liquid polyethylene wax inside is provided on one side of the support plate 101. A feed hole 113 for feeding material is provided at the top of the processing cylinder 108.
[0033] The stirring assembly includes a support arm 103 fixedly mounted on the top of a support plate 101. One end of the support arm 103 extends upward toward the processing cylinder 108. A connecting rod 104 is inserted into the end of the support arm 103 above the processing cylinder 108. One end of the connecting rod 104 extends downward into the inner cavity of the processing cylinder 108. A connecting plate 500 is fixedly connected to the end of the connecting rod 104 inside the processing cylinder 108. Several sets of stirring plates 501 are fixedly mounted on the outer surface of the connecting plate 500. A fixing assembly for fixing the connecting rod 104 is provided above the end of the support arm 103 at the upper part of the processing cylinder 108. The connecting rod 104 extends to the inner cavity of the processing cylinder 108 at one end, the connecting plate 500 is fixed to the end of the connecting rod 104, and the stirring plate 501 is installed on the outer surface of the connecting plate 500. When the centrifugal assembly rotates the protective cylinder 110, the connecting rod 104 remains stationary, so that the connecting plate 500 and the stirring plate 501 located in the cylinder can stir the polyethylene wax in the processing cylinder 108. This can make the polyethylene wax in the cylinder flow continuously, promote the heat transfer in the material more evenly, and make the polyethylene wax mix more evenly during the melting process, thereby ensuring uniform temperature distribution and effectively solving the problem of uneven temperature of the material in the cylinder.
[0034] The fixing assembly includes a guide ring 105 fixedly installed above the end of the support arm 103 and at a corresponding position on the outer circumference of the connecting rod 104. A fixing bolt 107 is threadedly connected to one side of the guide ring 105. One end of the fixing bolt 107 is threaded through the guide ring 105 and abuts against the surface of the connecting rod 104. A handle 106 is fixedly installed on the top of the connecting rod 104. Through the setting of the fixing assembly, the guide ring 105 and the fixing bolt 107 fix the connecting rod 104, ensuring that the connecting rod 104 will not shake during the stirring process, thus ensuring the stability and reliability of the stirring. At the same time, the handle 106 on the top of the connecting rod 104 makes it convenient for the operator to manually operate the connecting rod 104 and adjust the height of the stirring plate 501.
[0035] The rotating assembly includes bearings 109 fixedly sleeved on the upper and lower surfaces of the processing cylinder 108. Support frames 102 are fixedly sleeved on the outer circular surface of the bearings 109. The ends of the two sets of support frames 102 are fixedly connected to the surface of the support plate 101. Through the setting of the rotating assembly, the structure of bearings 109 and support frames 102 allows the processing cylinder 108 to rotate flexibly. Furthermore, the bearings 109 reduce friction during rotation, reduce energy loss, and ensure the stability and accuracy of rotation. At the same time, the support frames 102 firmly connect the processing cylinder 108 to the support plate 101, enhancing the overall structural strength of the equipment and ensuring that the processing cylinder 108 will not shift or shake during centrifugation.
[0036] The heating assembly includes several sets of heating rods 300 fixedly inserted into the top of the fixing ring 112. The heating ends of the heating rods 300 extend between the protective cylinder 110 and the processing cylinder 108. By setting the heating assembly, the heating rods 300 are fixedly inserted into the top of the fixing ring 112, and their heating ends extend between the protective cylinder 110 and the processing cylinder 108. This allows for uniform heating of the polyethylene wax inside the processing cylinder 108, ensuring that the polyethylene wax receives sufficient heat in all parts, avoiding local overheating or undercooling, and improving the melting effect. Furthermore, the heating rods 300 directly transfer heat to the processing cylinder 108, reducing heat loss during the heat transfer process, improving heating efficiency, shortening heating time, and reducing energy consumption.
[0037] A heat-conducting layer 301 is provided in the inner cavity between the protective cylinder 110 and the processing cylinder 108. The heat-conducting layer 301 can distribute heat evenly, making the temperature inside the processing cylinder 108 more uniform and ensuring the quality stability of polyethylene wax during the melting process.
[0038] The thermal conductive layer 301 is one or two of the following: thermal conductive oil and silicone oil.
[0039] The detachable component includes an external thread 400 on the outer circular surface of the opening of the processing cylinder 108, and an internal thread 401 on the inner wall of the cylinder cover 111 that matches the external thread 400. The internal thread 401 of the cylinder cover 111 is threadedly connected to the opening of the processing cylinder 108 by the external thread 400. The detachable component effectively prevents the leakage of molten polyethylene wax, ensuring the safety and cleanliness of the processing process. The cylinder cover 111 can be easily installed or removed by rotating it, which facilitates the cleaning and maintenance of the inside of the processing cylinder 108 and the removal of the centrifuged polyethylene wax.
[0040] The centrifugal assembly includes a drive motor 202 embedded in one side surface of a support plate 101. The output shaft of the drive motor 202 is keyed to a drive rod 201. A gear 200 is fixedly connected to the end of the drive rod 201. The gear 200 is rotatably connected to one side surface of the support plate 101. A gear ring 203 is fixedly fitted on the surface of the protective cylinder 110 at a corresponding position to the gear 200. The gear ring 203 meshes with the gear 200. Through the centrifugal assembly, the transmission structure of the drive motor 202, drive rod 201, gear 200, and gear ring 203 can provide stable centrifugal power. The output shaft of the drive motor 202 is keyed to the drive rod 201 to ensure the reliability of power transmission. The meshing transmission of the gear 200 and gear ring 203 ensures the rotational stability and accuracy of the protective cylinder 110.
[0041] In use, the cylinder cover 111 is threadedly connected to the outer thread 400 on the outer surface of the opening of the processing cylinder 108 through the internal thread 401 on its inner wall. The cylinder cover 111 is rotated to tighten it, ensuring a good seal at the connection and preventing leakage of molten polyethylene wax during processing. An appropriate amount of polyethylene wax raw material is added into the processing cylinder 108 through the feed hole 113 at the top of the processing cylinder 108.
[0042] Tighten the fixing bolt 107 on one side of the guide ring 105 so that one end of the fixing bolt 107 abuts against the surface of the connecting rod 104, thereby fixing the connecting rod 104 and ensuring that the connecting rod 104 will not shake during the stirring process.
[0043] Activating the heating assembly means energizing the heating rod 300, which is fixedly inserted into the top of the fixing ring 112. The heating end of the heating rod 300 transfers heat to the heat-conducting layer 301 between the protective cylinder 110 and the processing cylinder 108. The heat-conducting layer 301 then evenly transfers the heat to the polyethylene wax inside the processing cylinder 108, causing the polyethylene wax to gradually heat up to a molten state.
[0044] When the drive motor 202 starts working, its output shaft drives the drive rod 201 to rotate. The gear 200 at the end of the drive rod 201 rotates accordingly. The gear 200 meshes with the toothed ring 203 on the surface of the protective cylinder 110. The rotation of the gear 200 will drive the protective cylinder 110 to rotate, thereby causing the liquid polyethylene wax in the processing cylinder 108 to undergo centrifugal treatment under the action of centrifugal force, realizing the separation of polyethylene wax from existing impurities or air bubbles. At the same time, the impurities move to the edge of the polyethylene wax under the action of centrifugal force.
[0045] During the rotation of the protective cylinder 110, the connecting rod 104 remains stationary, thereby the connecting plate and the stirring plate 501 located inside the processing cylinder 108 stir the polyethylene wax inside the processing cylinder 108, making the polyethylene wax more uniformly mixed during the melting process, ensuring uniform temperature distribution, and also helping to improve the melting effect of the polyethylene wax.
[0046] After centrifugation, turn off the drive motor 202 and the heating component. After the polyethylene wax in the processing cylinder 108 has cooled to a certain degree, unscrew the cylinder cover 111, take out the processed polyethylene wax from the processing cylinder 108, and cut the polyethylene wax, removing the parts with impurities.
[0047] In summary, in the embodiment of this utility model, a polyethylene wax melting centrifugal separation device has a connecting rod 104 extending to the inner cavity of the processing cylinder 108 at one end, a connecting plate 500 fixed to the end of the connecting rod 104, and a stirring plate 501 installed on the outer surface of the connecting plate 500. When the centrifugal assembly rotates the protective cylinder 110, the connecting rod 104 remains stationary, thereby the connecting plate 500 and the stirring plate 501 located inside the cylinder stir the polyethylene wax in the processing cylinder 108. This allows the polyethylene wax inside the cylinder to flow continuously, promoting a more uniform heat transfer in the material. This enables the polyethylene wax to mix more evenly during the melting process, thereby ensuring a uniform temperature distribution and effectively solving the problem of uneven material temperature inside the cylinder.
