[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0038] Please refer to Figure 1 , which is a flowchart of the method for purifying wax in the embodiments of the present invention.
[0039] The method for purifying wax in the embodiments of the present invention includes:
[0040] Step S101: Pour the melted wax to be processed into a glass film former, and coat the wax to be processed into a thin film;
[0041] Step S102: Place the glass film former into a vacuum drying oven for vacuum drying treatment;
[0042] Step S103: Peel off the thin film in the glass film former after vacuum drying treatment, and add the peeled thin film to a first xanthan gum solution for stirring and mixing to obtain a first mixture;
[0043] Step S104: Pour the first mixture into a mixing bucket, add alcohol, and stir to mix, obtaining a second mixture.
[0044] Step S105: Filter the second mixture, add water to the filtered second mixture, and stir to mix, obtaining a third mixture.
[0045] Step S106: Filter the third mixture, pour the filtered third mixture into a filtration centrifuge for centrifugation, obtaining a centrifugation residue.
[0046] Step S107: Add the centrifugation residue to a second xanthan gum solution for mixing, obtaining a fourth mixture.
[0047] Step S108: Add the fourth mixture to a high-speed stirrer for stirring, and dry the stirred fourth mixture, obtaining purified wax.
[0048] In an embodiment of the present invention, by utilizing the function of xanthan gum and the function of the filtration centrifuge, impurities and impure substances in the wax can be effectively removed, improving the purity of the wax.
[0049] The wax in the embodiment of the present invention refers to polyethylene wax. In specific implementation, the wax to be treated may be waste wax, for example. By recycling the waste wax, the purposes of saving resources and environmental protection are achieved.
[0050] In an optional implementation manner, before the step S101 "Pour the melted wax to be treated into a glass film former and place the glass film former in a vacuum drying oven for vacuum drying treatment", it further includes:
[0051] Sieve the wax to be treated, and heat and melt the sieved powdery wax.
[0052] In specific implementation, the wax to be treated may be mixed with wax of different sizes such as large chunks and powder. By first sieving out the powdery wax, it is convenient for subsequent sufficient heating and melting. In addition, the large chunks of wax can be crushed and other treatments to facilitate heating and melting. In specific applications, for example, a sieve or other device can be used to sieve the wax to be treated.
[0053] In an optional implementation manner, the coating the wax to be treated into a thin film specifically includes:
[0054] Coat the wax to be treated into a thin film with a thickness of 0.5 - 1.5 mm.
[0055] In specific implementation, the thickness of the thin film can be, for example, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, etc. Of course, the thickness of the thin film can also be set according to actual usage requirements and will not be elaborated further here. The inner lining thickness of the glass film former is, for example, 5 mm. In this embodiment, the wax to be processed in a molten state is coated inside the glass film former to form a thin film with a thickness of 0.5 - 1.5 mm, so as to facilitate uniform drying of the wax to be processed during subsequent vacuum drying treatment.
[0056] In an alternative implementation, the step S102 "put the glass film former into a vacuum drying oven for vacuum drying treatment" specifically includes:
[0057] Put the glass film former into a vacuum drying oven, control the temperature of the vacuum drying oven at 70 degrees Celsius, the vacuum degree at 30 Pa, and the vacuum drying time at 6 hours.
[0058] Specifically, the mass concentration of the first xanthan gum solution in step S103 is 5%, and the stirring time is 30 minutes. Of course, the mass concentration and stirring time of the first xanthan gum solution in step S103 can also be set to other values according to actual usage requirements and will not be elaborated further here.
[0059] In an alternative implementation, the step S104 "pour the first mixture into a mixing barrel and add alcohol for stirring and mixing to obtain a second mixture" specifically includes:
[0060] Pour the first mixture into a mixing barrel, add 83 - 85% alcohol for stirring and mixing, and the mixing time is 15 minutes to obtain a second mixture.
[0061] In this embodiment, adding 83 - 85% alcohol for stirring and mixing means that the mass of the added alcohol accounts for 83 - 85% of the mass of the first mixture, and can be, for example, 83%, 84%, 85%, etc. Of course, the amount of added alcohol can also be set to other values according to actual usage requirements and will not be elaborated further here.
[0062] In an alternative implementation, the step S105 "filter the second mixture and add water to the filtered second mixture for stirring and mixing to obtain a third mixture" specifically includes:
[0063] Filter the second mixture, and add 20% water to the filtered second mixture for stirring and mixing, and the mixing time is 30 minutes to obtain a third mixture.
[0064] In this embodiment, adding 20% water to the filtered second mixture for stirring and mixing means that the mass of the water added to the filtered second mixture accounts for 20% of the mass of the filtered second mixture.
[0065] In an alternative embodiment, step S106, "filter the third mixture, and pour the filtered third mixture into a filtration centrifuge for centrifugation to obtain a centrifugation residue", specifically includes:
[0066] Filter the third mixture;
[0067] Pour the filtered third mixture into a filtration centrifuge for centrifugation at a centrifugation speed of 1000 r / min for 10 minutes;
[0068] Take out the centrifuged third mixture and perform centrifugation again to obtain a centrifugation residue.
[0069] In specific implementation, after filtering the third mixture, for example, the filtered third mixture can be poured into a filtration centrifuge for centrifugation at a centrifugation speed of 1000 r / min for 10 minutes, and then the centrifugation residue is taken out and centrifuged again. The process parameters of the second centrifugation can be the same as or different from those of the first centrifugation. For example, the centrifugation speed of the second centrifugation is less than or greater than 1000 r / min, and the centrifugation time is less than or greater than 10 minutes, which is specifically set according to actual usage requirements. Through the above multiple filtrations and the above two centrifugations in this embodiment, impurities and impure substances in the wax are fully removed, thereby improving the purity of the wax.
[0070] In an alternative embodiment, step S107, "add the centrifugation residue to the second xanthan gum solution for mixing to obtain a fourth mixture", specifically includes:
[0071] Add the centrifugation residue to a second xanthan gum solution with a mass concentration of 1% for mixing, and stir for 30 minutes to obtain a fourth mixture.
[0072] In an alternative embodiment, step S108, "add the fourth mixture to a high-speed stirrer for stirring, and dry the stirred fourth mixture to obtain purified wax", specifically includes:
[0073] Add the fourth mixture to a high-speed stirrer for stirring for 20 minutes;
[0074] The fourth mixture after stirring treatment is dried at a temperature controlled at 70 degrees Celsius for 12 hours to obtain purified wax.
[0075] In a specific implementation, after adding the fourth mixture to a high-speed stirrer for stirring treatment, for example, the stirred fourth mixture can be poured into a drying chamber for drying treatment at a temperature controlled at 70 degrees Celsius for 12 hours to obtain purified wax.
[0076] In an alternative implementation, the filtration centrifuge includes a controller, a centrifugal drum, and a speed sensor; the controller is electrically connected to the centrifugal drum and the speed sensor respectively; the controller is configured to:
[0077] Control the centrifugal drum to rotate at a target speed;
[0078] Receive the speed of the centrifugal drum detected by the speed sensor;
[0079] When the difference between the received speed of the centrifugal drum and the target speed exceeds a preset speed threshold, update the target speed based on the difference between the speed of the centrifugal drum and the target speed, and return to the step of controlling the centrifugal drum to rotate at the target speed.
[0080] In a specific implementation, the user inputs a target speed to the filtration centrifuge, and the controller controls the centrifugal drum to rotate according to the target speed. The speed sensor can detect the speed of the centrifugal drum in real time and send it to the controller. In practical applications, although the controller controls the centrifugal drum to rotate according to the target speed, due to mechanical errors and other reasons, it is difficult for the centrifugal drum to rotate precisely at the target speed. Therefore, the speed detected by the speed sensor in real time for the centrifugal drum is not equal to the target speed. In this embodiment, when the difference between the received speed of the centrifugal drum and the target speed exceeds the preset speed threshold, it indicates that the actual speed of the centrifugal drum is quite different from the set target speed. At this time, update the target speed based on the difference between the speed of the centrifugal drum and the target speed, and control the centrifugal drum to rotate at the updated target speed to improve the speed control accuracy of the filtration centrifuge. It should be noted that the preset speed threshold can be set according to the actual usage requirements of the user.
[0081] In an alternative implementation, the step of when the difference between the received speed of the centrifugal drum and the target speed exceeds the preset speed threshold, updating the target speed based on the difference between the speed of the centrifugal drum and the target speed, and returning to the step of controlling the centrifugal drum to rotate at the target speed specifically includes:
[0082] When the difference between the received rotational speed of the centrifuge drum and the target rotational speed exceeds a preset rotational speed threshold, determine a rotational speed compensation amount based on the difference between the rotational speed of the centrifuge drum and the target rotational speed;
[0083] Update the target rotational speed based on the rotational speed compensation amount, and return to the step of controlling the centrifuge drum to rotate at the target rotational speed.
[0084] Exemplarily, when the difference between the received rotational speed of the centrifuge drum and the target rotational speed exceeds a preset rotational speed threshold, determining a rotational speed compensation amount based on the difference between the rotational speed of the centrifuge drum and the target rotational speed specifically includes:
[0085] When the difference between the received rotational speed of the centrifuge drum and the target rotational speed exceeds a preset rotational speed threshold, determine the rotational speed compensation amount corresponding to the difference between the rotational speed of the centrifuge drum and the target rotational speed according to the mapping relationship between the pre-configured rotational speed difference and the rotational speed compensation amount and the difference between the rotational speed of the centrifuge drum and the target rotational speed.
[0086] In this embodiment, by pre-configuring the mapping relationship between the rotational speed difference and the rotational speed compensation amount between the rotational speed of the centrifuge drum and the target rotational speed, in actual use, the rotational speed compensation amount corresponding to the difference between the current rotational speed and the target rotational speed of the centrifuge drum can be determined according to this mapping relationship and the difference between the current rotational speed and the target rotational speed of the centrifuge drum, so that the target rotational speed can be quickly updated based on this rotational speed compensation amount, and then the rotational speed of the centrifuge drum can be quickly adjusted.
[0087] Exemplarily, updating the target rotational speed based on the rotational speed compensation amount specifically includes:
[0088] Calculate the updated target rotational speed through the following formula:
[0089] R2 = R1 * A
[0090] Wherein, R2 is the updated target rotational speed; R1 is the target rotational speed before update; A is the rotational speed compensation amount.
[0091] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: The embodiments of the present invention provide a method for purifying wax. Pour the melted wax to be treated into a glass film former, and coat the wax to be treated into a thin film. Then, place the glass film former in a vacuum drying oven for vacuum drying treatment. Next, peel off the thin film, and add the peeled thin film to a first xanthan gum solution for stirring and mixing to obtain a first mixture. Then, pour the first mixture into a mixing bucket, and add alcohol for stirring and mixing to obtain a second mixture. Filter the second mixture, and add water to the filtered second mixture for stirring and mixing to obtain a third mixture. Next, filter the third mixture, and pour the filtered third mixture into a filtration centrifuge for centrifugation to obtain a centrifugation residue. Then, add the centrifugation residue to a second xanthan gum solution for mixing to obtain a fourth mixture. Further, add the fourth mixture to a high-speed stirrer for stirring treatment, and dry the stirred fourth mixture to obtain the purified wax. In this way, the embodiments of the present invention can effectively remove impurities and impure substances in the wax and improve the purity of the wax by utilizing the function of xanthan gum and the function of the filtration centrifuge. In addition, the embodiments of the present invention can recycle waste wax, achieving the purposes of saving resources and environmental protection.
