Description

Technical Field

[0001] The invention relates to the technical field of unloading centrifuges, and in particular to a beauty product concentrate centrifugal device and method. Background Art

[0002] Scraper unloading centrifuge is mainly used for centrifugal filtration and scraper unloading of raw materials in chemical, light industry, food, biology, pharmaceutical and cosmetic industries. Especially in the field of beauty products, plant extract raw liquid needs to be centrifuged in the actual mass production process. Some plant extract raw liquid contains substances with high viscosity or oily substances, which makes centrifugation and cleaning more difficult.

[0003] Chinese patent application publication number CN113893957A discloses a discharging device of a horizontal scraper discharging centrifuge, comprising a scraper assembly, a discharging assembly, and a cylinder. The discharging assembly is arranged below the scraper assembly, a piston rod is arranged in the cylinder, the scraper assembly comprises a bearing seat, a first bearing and a second bearing, a scraper shaft, a connecting rod arranged at one end of the scraper shaft, and a scraper part arranged at the other end of the scraper shaft, the discharging assembly comprises a reducer, a discharging cylinder, and a spiral wheel; a first sleeve is arranged in a first gland, the first sleeve is sleeved on the spiral wheel, a first pneumatic sealing ring is sleeved on the first sleeve, a first gas channel is arranged on the first pneumatic sealing ring, a first gas path is arranged in the inner wall of the first gland, a second sleeve is arranged in the second gland, the second sleeve sealing sleeve is arranged on the spiral wheel, a second pneumatic sealing ring is sleeved on the second sleeve, a second gas path is arranged on the second pneumatic sealing ring, and a second gas path is arranged in the inner wall of the second gland. The structure of the invention has good scraping and unloading effects, long service life and good sealing performance.

[0004] The working principle of the existing centrifuge is that after the material is added, when the suspension rotates at high speed in the drum together with the drum, due to the action of centrifugal force, the solid particles are trapped on the filter cloth to form filter residue, and the filtrate is thrown out through the filter residue, the pores of the filter cloth and the small holes on the back side of the drum wall; the filtered filter cake is scraped off by the discharge scraper and discharged along the discharge hopper; after discharge, washing liquid is introduced from the liquid inlet to clean the scraper and the remaining filter cake, and the waste liquid after cleaning is discharged through the return pipe by siphon effect.

[0005] However, the above-mentioned scraper unloading centrifuge relies on subjective factors to determine the working timing of each component, and the working timing of centrifugal filtration and equipment cleaning is not accurately determined, which can easily lead to incomplete cleaning and material stickiness in the subsequent scraper unloading process, thereby reducing the scraping efficiency of the scraper or excessive impurities in the material. Summary of the invention

[0006] In order to overcome the problem in the prior art that the working timing of centrifugal filtration and equipment cleaning of a scraper unloading centrifuge is not accurately determined, which leads to poor scraper unloading effect, a beauty product concentrate centrifugal device and method are provided.

[0007] The present invention provides a beauty product liquid centrifugal device, comprising:

[0008] Liquid inlet pipe, discharge chamber, return pipe, controller, and drum and scraper in the discharge chamber:

[0009] A plurality of detection chambers are provided below the drum, and the output end of each detection chamber is connected to an output pipe, in which an ultrasonic flow meter is provided to measure the flow velocity of the waste liquid;

[0010] A camera is arranged above each of the detection chambers to collect images of the detection chambers, and the controller determines the content of the corresponding liquid in the detection chambers and the impurity content in the waste liquid according to the images of the detection chambers;

[0011] The controller determines whether the drum stops working according to the amount of filtrate in each detection chamber per unit time during the centrifugation stage, and determines whether the liquid inlet pipe stops feeding liquid according to the flow rate and the impurity content during the cleaning stage.

[0012] Furthermore, the control instrument determines that each of the detection chambers starts to work in response to the preset state of the liquid inlet amount of the liquid inlet pipe and the liquid discharge amount of the return pipe;

[0013] The preset state satisfies that the ratio of the discharge amount to the intake amount in the cleaning stage does not change within a unit time.

[0014] Furthermore, the control instrument determines whether the liquid inlet pipe stops inletting liquid according to the impurity content in each of the detection chambers and the flow rate of the waste liquid output from the detection chamber;

[0015] Wherein, the control instrument determines that the liquid inlet pipe stops inletting liquid when the impurity content in the detection chamber is less than a first preset value and the flow speed is greater than a preset speed.

[0016] Furthermore, the control instrument determines whether the drum stops working according to the amount of filtrate received by each detection chamber within a unit time;

[0017] Wherein, the control instrument controls each of the detection chambers to start working during the centrifugal stage.

[0018] Furthermore, the controller determines that the drum stops working by satisfying both the filtrate quantity condition and the filtrate distribution condition;

[0019] The filtrate amount condition is that the total amount of filtrate received by each of the detection chambers is less than a second preset value.

[0020] Furthermore, the filtrate distribution condition of the controller is that the amount of filtrate received by each detection chamber is less than one third of the second preset value.

[0021] Furthermore, a chamber cover that can be opened and closed is provided above the detection chamber, and a control valve for controlling the discharge of liquid is provided below.

[0022] Furthermore, the control device is provided with a closing condition of the bin cover, and controls the bin cover to close when the closing condition is met;

[0023] The chamber cover is opened when the detection chamber starts to work, and the closing condition is satisfied when the chamber is in the cleaning stage and the detection chamber is full of filtrate or waste liquid.

[0024] Further, the control instrument controls the control valve to open in response to the drainage condition;

[0025] The drainage condition is met and the camera completes collecting the image of the detection chamber.

[0026] Furthermore, the present invention also provides a method for centrifuging a cosmetic product stock solution, comprising:

[0027] The original liquid of the beauty product is introduced into the discharge chamber through the liquid inlet pipe for centrifugation.

[0028] Compared with the prior art, the beneficial effect of the present invention lies in that, by arranging the detection chamber below the drum and the output pipe below the detection chamber, the stopping timing of the cleaning process and the drum centrifugal filtration process can be automatically determined, and the cleaning effect can be effectively improved while avoiding excessive use of the equipment, thereby avoiding the influence of incomplete cleaning of the scraper and the drum on the next centrifugal unloading process, thereby effectively improving the unloading effect of the scraper unloading centrifuge.

[0029] Furthermore, the detection chamber of the present invention is opened to work when the ratio of the discharge volume of the return pipe to the liquid inlet volume of the liquid inlet pipe does not change within a unit time. When the ratio of the discharge volume of the return pipe to the liquid inlet volume of the liquid inlet pipe does not change within a unit time, it means that there are fewer impurities and additional waste liquid in the equipment that affect the discharge volume, and the cleaning process is basically completed. The waste liquid and residue in the equipment are effectively cleaned. At this time, the work of the detection chamber can effectively analyze whether the cleaning process is effective, thereby further improving the unloading effect of the scraper unloading centrifuge.

[0030] Furthermore, the controller of the present invention determines that the liquid inlet pipe stops inletting when the impurity content in the detection bin is less than a first preset value and the flow rate of the waste liquid is greater than a preset speed. The impurities that can be detected in the detection bin are fine material residues or impurities carried by the material, which can be detected through images, but the oily impurities in the waste liquid that are the same color as the washing liquid cannot be effectively detected. Since the flow rate in the output pipe is different when the content of oily impurities in the waste liquid is different, the flow rate of the waste liquid detected in the output pipe can effectively determine whether the oily impurities in the waste liquid are effectively cleaned, thereby further improving the unloading effect of the scraper unloading centrifuge.

[0031] Furthermore, the detection chamber of the present invention can effectively determine whether the filtrate is effectively filtered out during the filtering and centrifuging process of the centrifuge. When the filtrate collected by each detection chamber is relatively small, it indicates that the filtrate in the drum is effectively filtered out, further improving the unloading effect of the scraper unloading centrifuge.

[0032] Furthermore, the processor of the present invention controls the bin cover and the control valve to open and close at corresponding times, which can further optimize the functions of the detection bin and the output pipe, and further improve the unloading effect of the scraper unloading centrifuge.

[0038] In order to make the objects and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with embodiments; it should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0040] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] See also Figure 1 and Figure 2As shown, Figure 1 This is a schematic diagram of the working structure of the beauty product concentrate centrifugation device according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of the recovery bin of an embodiment of the present invention. This embodiment provides a working structure of a beauty product concentrate centrifugal device using the present invention, including:

[0042] The liquid inlet pipe 9, the discharge chamber 11, the water return pipe 6, the controller (not shown in the figure), and the drum 2 and the scraper 8 in the discharge chamber 11 are arranged in the housing 1:

[0043] A plurality of detection chambers 5 are provided below the drum 2, and the output end of each detection chamber 5 is connected to an output pipe 13, in which an ultrasonic flow meter is provided to measure the flow velocity of the waste liquid;

[0044] In this embodiment, the preferred value of the number of detection chambers is 3, and the number of detection chambers can be set according to the specifications of the centrifuge.

[0045] A camera is arranged above each detection chamber 5 to collect the detection chamber image, and the controller determines the content of the corresponding liquid in the detection chamber 5 and the impurity content in the waste liquid according to the detection chamber image; the present invention does not limit the installation position of the camera, and it is sufficient to be able to collect the image in the detection chamber, which will not be repeated here.

[0046] The above working structure performs centrifugal unloading in the centrifugal stage. The suspension of the material enters the drum 2 through the feed pipe 10. When the suspension rotates at high speed in the drum along with the drum 2 driven by the motor 4, due to the action of centrifugal force, the solid particles are trapped on the filter cloth on the inner surface of the drum 2 to form filter residue, and the filtrate is thrown out through the filter residue, the pores of the filter cloth and the small holes on the drum wall. The filtered filter cake is scraped off by the scraper 8 and discharged to the discharge channel 3 along the discharge hopper 7. Another motor is arranged in the discharge channel 3 to drive the internal spiral discharge blade to discharge the material (not shown in the figure).

[0047] After the discharge is completed, the cleaning stage begins, and washing liquid is introduced from the liquid inlet 9 to clean the scraper 8 and the remaining filter cake. The waste liquid after cleaning is discharged through the return pipe 6 by siphon effect.

[0048] Specifically, the present invention does not limit the method of obtaining impurities based on images. An image processing algorithm that can identify corresponding functions can be pre-trained and imported into the controller for implementation. In this embodiment, the captured liquid image can be binarized and cluster analysis can be performed to identify the clusters corresponding to the impurities, and then the impurities can be identified to obtain the number of impurities. The number of impurities in the captured area is determined as the impurity content. Of course, preferably, in order to ensure the accuracy of identification, impurities that are too small are not included in the calculation. In this embodiment, only impurities with a diameter greater than 1 mm are considered.

[0049] Specifically, there is no specific limitation on the method of obtaining the content of liquid in the detection chamber. A reference scale can be set on the inner wall of the detection chamber, and the position characteristics of the liquid surface relative to the reference scale can be obtained by image acquisition to obtain the content of liquid in the detection chamber. This is a prior art and will not be described in detail.

[0050] Please combine Figure 1 See also Figure 3 As shown, Figure 3 This is a structural block diagram of a beauty product concentrate centrifugal device according to an embodiment of the present invention. In the centrifugal stage, the controller determines whether the drum stops working according to the amount of filtrate in each detection chamber per unit time. In the cleaning stage, the controller determines whether the liquid inlet pipe stops feeding liquid according to the flow rate and impurity content.

[0051] Specifically, the amount of filtrate can be obtained by calculating the flow rate through the cross-sectional area of ​​the output pipe and the flow rate of the liquid flowing through the output pipe, and the flow rate per unit time is taken as the above-mentioned filtrate amount, which will not be repeated here.

[0052] The present invention does not limit the specific structure of the controller, and the controller may be a host computer or a control computer connected to the corresponding components.

[0053] In the above embodiment, by setting the detection chamber below the drum and the output pipe below the detection chamber, the stopping time of the cleaning process and the drum centrifugal filtration process can be automatically determined, which can effectively improve the cleaning effect while avoiding excessive use of the equipment, thereby avoiding the influence of incomplete cleaning of the scraper and the drum on the next centrifugal unloading process, thereby effectively improving the unloading effect of the scraper unloading centrifuge.

[0054] Specifically, the control instrument determines that each detection chamber starts working in response to the preset state of the liquid inlet amount of the liquid inlet pipe and the liquid discharge amount of the return pipe;

[0055] The preset state satisfies that the ratio of the discharge volume to the intake volume in the cleaning stage does not change within a unit time.

[0056] In the above embodiment, the detection chamber is opened for operation when the ratio of the discharge volume of the return pipe to the liquid inlet volume of the liquid inlet pipe does not change within a unit time. When the ratio of the discharge volume of the return pipe to the liquid inlet volume of the liquid inlet pipe does not change within a unit time, it indicates that there are fewer impurities and additional waste liquid in the equipment that affect the discharge volume, and the cleaning process is basically completed. The waste liquid and residue in the equipment are effectively cleaned. At this time, the operation of the detection chamber can effectively analyze whether the cleaning process is effective, thereby further improving the unloading effect of the scraper unloading centrifuge.

[0057] See also Figure 4 As shown, Figure 4 This is a flow chart for determining whether the liquid inlet pipe stops inletting according to an embodiment of the present invention. The controller determines whether the liquid inlet pipe stops inletting according to the impurity content in each detection chamber and the flow rate of the waste liquid output from the detection chamber.

[0058] The control device determines that the liquid inlet pipe stops inletting liquid when the impurity content in the detection chamber is less than a first preset value and the flow speed is greater than a preset speed.

[0059] In the above embodiment, the controller determines that the liquid inlet pipe stops inletting when the impurity content in the detection chamber is less than the first preset value and the flow rate of the waste liquid is greater than the preset speed. The impurities that can be detected in the detection chamber are fine material residues or impurities carried by the material, which can be detected by image, but the oily impurities in the waste liquid that are the same color as the washing liquid cannot be effectively detected. Since the flow rate in the output pipe is different when the content of oily impurities in the waste liquid is different, the flow rate of the waste liquid detected in the output pipe can effectively determine whether the oily impurities in the waste liquid are effectively cleaned, thereby further improving the unloading effect of the scraper unloading centrifuge.

[0060] Specifically, the controller determines whether the drum stops working according to the amount of filtrate received by each detection chamber in a unit time;

[0061] Among them, the controller controls each detection chamber to start working during the centrifugal stage.

[0062] Specifically, the controller determines that the drum stops working by satisfying both the filtrate quantity condition and the filtrate distribution condition;

[0063] The filtrate quantity condition is that the total amount of filtrate received by each detection chamber is less than a second preset value.

[0064] Specifically, the filtrate distribution condition of the controller is that the amount of filtrate received by each detection chamber is less than one third of the second preset value.

[0065] In the above embodiment, the detection chamber can effectively determine whether the filtrate is effectively filtered out during the centrifugation stage of the centrifuge. When the filtrate collected by each detection chamber is small, it means that the filtrate in the drum is effectively filtered out, further improving the unloading effect of the scraper unloading centrifuge.

[0066] In implementation, the first preset value is determined according to the cleaning standard of the material, and the preset speed can be determined based on a limited number of tests on the output speed in the output pipe under different oil material contents of the material components. It is sufficient to meet the cleaning standard when the waste liquid is output at a speed greater than the preset speed. The second preset value and the setting of the filtrate distribution conditions are similar, as long as the corresponding filtration standards are met, and they will not be repeated here.

[0067] Specifically, a chamber cover that can be opened and closed is provided above the detection chamber, and a control valve for controlling the discharge of liquid is provided below.

[0068] Specifically, the control instrument is provided with a closing condition of the compartment cover, and controls the compartment cover to close when the closing condition is met;

[0069] The chamber cover is opened when the detection chamber starts to work, and the closing condition is met when it is in the cleaning stage and the detection chamber is full of filtrate or waste liquid.

[0070] Specifically, the controller controls the control valve to open in response to the drain condition;

[0071] When the drainage conditions are met, the camera completes collecting the image of the detection chamber.

[0072] In the above embodiment, the processor controls the bin cover and the control valve to open and close at corresponding times, which can further optimize the functions of the detection bin and the output pipe and further improve the unloading effect of the scraper unloading centrifuge.

[0073] Specifically, the present invention also provides a method for centrifuging a cosmetic product stock solution, comprising:

[0074] The original liquid of the beauty product is introduced into the discharge chamber through the liquid inlet pipe for centrifugation.

[0075] The original solution of beauty products includes plant extracts or animal extracts;

[0076] It is understandable that in the prior art, some plant extracts or animal extracts can be used in beauty products, such as facial masks or skin care products, after centrifugation;

[0077] Common plant extracts include aloe vera extract, olive extract, camellia seed extract, etc., which will not be described in detail here;

[0078] Animal extracts, such as beeswax, lanolin, etc., are not described here.

[0079] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
