Description

Technical Field

[0001] This utility model relates to the technical field of surface treatment equipment for coating raw materials, and in particular to an integrated adsorption and drying device in the synthesis process of carbon / pearl pigments. Background Technology

[0002] Pearl pigments are a type of optical effect pigment, while also Pearl pigments are transparent, flake-like pigments that display vibrant colors through the action of light. In practical applications, pearl pigments are often applied to dark substrates, taking advantage of the opacity of the dark substrate to better showcase the colors of the pearl pigments.

[0003] In reality, to facilitate better use of pearlescent pigments by consumers, a layer of carbon black or iron oxide black particles is often coated onto the surface of the pigment through chemical adsorption, thus giving the pearlescent pigment its dark base. However, this chemical adsorption method, when combined with high-speed dispersion and external forces, can cause the surface coating to peel off, resulting in the pearlescent color losing its original application effect.

[0004] To address the aforementioned technical challenges, existing pearlescent pigment production processes can be broadly categorized into four steps: raw material pretreatment, organic matter adsorption, high-temperature low-oxygen combustion, and post-treatment. Organic matter adsorption aims to form a carbon layer on the pearlescent surface, thereby improving the pearlescent effect. This is achieved by uniformly coating the pearlescent surface with pyrolysis oil (such as heavy petroleum, asphalt, or other hydrocarbon-rich organic liquids). The typical practice for this step is to immerse the pearlescent pigment in the pyrolysis oil, which can take anywhere from several hours to several days.

[0005] To accelerate adsorption and improve overall preparation efficiency, the pyrolysis oil and pearlescent pigment can be intermittently mixed and stirred during the soaking process to ensure uniform adsorption of organic matter on the surface of the pearlescent pigment. However, in existing technologies, most methods simply involve prolonged mixing and soaking, neglecting the stirring step, which leaves room for improvement in the adsorption speed and effectiveness of the pearlescent pigment and organic matter. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides an integrated adsorption and drying device for the synthesis of carbon / pearl pigments. This integrated adsorption and drying device, which is designed for the carbon precursor coated on the surface of pearl pigments, can intermittently mix and stir the pearl pigments and pyrolysis oil, thereby accelerating the adsorption rate of organic matter and improving the uniform adsorption effect.

[0007] According to an embodiment of this utility model, an integrated adsorption and drying device for the synthesis process of carbon / pearl pigments includes: an immersion tank with an installation port at its upper end; a drying tank slidably disposed vertically at the installation port of the immersion tank, with several through holes on the four side walls of the bottom of the drying tank; a lifting assembly installed between the immersion tank and the drying tank for driving the drying tank to slide up and down away from or towards the immersion tank; and a stirring assembly including a first motor, a stirring shaft, and an intermittent mechanism. The first motor is fixedly installed at the bottom of the immersion tank, and the stirring shaft rotatably passes through the bottom wall of the immersion tank. The first motor is connected to the stirring shaft via the intermittent mechanism, and the portion of the stirring shaft located inside the immersion tank is provided with multiple blades.

[0008] The technical principle of this invention is as follows: Pearl pigment is placed in a drying chamber and lowered into an immersion chamber via a lifting assembly. The pyrolysis oil flows into the drying chamber through the openings around its perimeter, ensuring the pearl pigment is completely immersed in the pyrolysis oil. To accelerate the adsorption speed, the operator starts the first motor. The output shaft of the first motor, under the action of an intermittent mechanism, drives the stirring shaft to rotate intermittently. The blades evenly mix the pearl pigment and the pyrolysis oil, improving the overall organic matter adsorption efficiency. After the predetermined immersion time is reached, the operator turns off the first motor and restarts the lifting assembly, lifting the drying chamber upwards and separating it from the immersion chamber for subsequent drying steps.

[0009] Preferably, the intermittent mechanism includes a first drive wheel, a complete gear, a first drive belt, and a partial gear. The first drive wheel is fixedly sleeved on the bottom end of the stirring shaft. The complete gear is rotatably disposed on the outer wall of the soaking tank. The partial gear is connected to the output shaft of the first motor, and the complete gear and the partial gear mesh and drive each other. The first drive belt is disposed between the first drive wheel and the complete gear.

[0010] By adopting the above technical solution, the stirring shaft will rotate intermittently only when the incomplete gear and the complete gear mesh with each other, through the first transmission wheel and the first transmission belt, etc., so as to uniformly mix the pearlescent pigment and the pyrolysis oil, accelerate the adsorption and improve the effect.

[0011] Preferably, the lifting assembly includes a threaded rod, a second motor, a limiting rod, and a horizontal plate. The threaded rod is rotatably mounted on the upper end of the soaking tank in a vertical direction, and the output shaft of the second motor is coaxially and fixedly connected to the threaded rod. A first moving block is threadedly connected to the threaded rod. The limiting rod is fixedly mounted on the upper end of the soaking tank away from the threaded rod, and a second moving block is slidably mounted on the limiting rod. The horizontal plate is fixedly mounted between the first and second moving blocks and is fixedly connected to the drying chamber.

[0012] By adopting the above technical solution, the second motor drives the threaded rod to rotate, which can eventually move the horizontal plate and the drying box upward, lift the drying box to separate it from the soaking box, and the pyrolysis oil flows out of the drying box through the through hole for subsequent drying treatment.

[0013] Preferably, the horizontal plate is also provided with a drying component, which includes a hot air blower and a ventilation mechanism. The hot air blower is installed on the horizontal plate and has multiple air outlets, each of which faces the inside of the drying chamber. The ventilation mechanism is connected to the air outlets of the hot air blower.

[0014] By adopting the above technical solution, the airflow of the hot air blower can be expanded under the action of the air distribution mechanism, thereby increasing the drying range, making the pearlescent pigments heat evenly, and improving the drying effect of the finished product.

[0015] Preferably, the air distribution mechanism includes a heat-resistant hose, a movable plate, and an eccentric wheel. The air outlet of the hot air blower is connected to a heat-resistant hose. The movable plate is slidably connected to the horizontal plate. Multiple openings are provided on the movable plate. The outlet ends of the heat-resistant hoses pass through the openings one by one and face the inside of the drying chamber. One end of the eccentric wheel slides against the movable plate. The eccentric wheel is connected to the first motor through a linkage mechanism.

[0016] By adopting the above technical solution, during the process of the eccentric wheel alternatingly contacting the long shaft end and the short shaft end with the movable plate, the movable plate will slide back and forth from side to side, causing the outlet end of the heat-resistant hose to swing back and forth from side to side, increasing the coverage of hot air and improving the uniform drying effect.

[0017] Preferably, the linkage mechanism includes a rotating shaft, a second transmission wheel, a drive shaft, and a connecting assembly; the eccentric wheel is rotatably connected to the horizontal plate via the rotating shaft, and the second transmission wheel is coaxially fixedly connected to the upper end of the rotating shaft after passing through the horizontal plate; the drive shaft is rotatably mounted on the outer wall of the soaking tank in a vertical direction, and the drive shaft is coaxially fixedly connected to the output shaft of the first motor, and the drive shaft and the rotating shaft are connected by a connecting assembly.

[0018] By adopting the above technical solutions, the energy consumption of this device can be reduced, and the cost expenditure can be decreased.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting up a stirring component, it can play an intermittent rotating and mixing role during long-term soaking operations, which accelerates the adsorption process between pearlescent pigments and pyrolysis oil organic matter, effectively improving the overall working efficiency and enhancing the adsorption effect.

[0021] 2. By setting up an immersion chamber, a drying chamber, and a lifting component, pearlescent pigments can be easily separated from pyrolysis oil. At the same time, they are dried in the drying chamber, integrating the two steps of organic matter adsorption and drying. This serves as a preparatory step for the subsequent high-temperature, low-oxygen combustion to form a thin and uniform carbon coating, greatly improving the preparation speed and the uniformity of the carbon coating, and correspondingly reducing preparation and labor costs.

[0022] 3. This application first uses immersion to adsorb a layer of carbon precursor (organic matter), and then forms a carbon layer on the pearlescent surface through high temperature and low oxygen combustion; this carbon layer is thin and uniform in thickness, has a strong bonding force with the pearlescent surface, and is not easy to fall off during actual use.

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and represent schematic diagrams, not actual pictures. They should not be construed as limiting the utility model. To better illustrate the embodiments of this utility model, some components in the figures may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable for those skilled in the art that some well-known mechanisms and their descriptions may be omitted in the figures.

[0029] In the figures of this utility model embodiment, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the figures are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances. In the description of this application, terms such as "first", "second", etc. are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figure 1-3 As shown in the figure, an embodiment of this utility model proposes an integrated adsorption and drying device for the synthesis process of carbon / pearl pigments, comprising: an immersion tank 1 with an installation port at its upper end; a drying tank 2, which is slidably disposed vertically at the installation port of the immersion tank 1, and has several through holes on the four sides of the bottom of the drying tank 2; a lifting assembly 3, which is installed between the immersion tank 1 and the drying tank 2, for driving the drying tank 2 to slide up and down away from or towards the immersion tank 1; and a stirring assembly 4, comprising a first motor 401, a stirring shaft 402, and an intermittent mechanism. The first motor 401 is fixedly installed on the outer wall of the immersion tank 1, and the output shaft of the first motor 401 is connected to the stirring shaft 402 through the intermittent mechanism. The stirring shaft 402 is rotatably connected to the immersion tank 1, and multiple blades are evenly installed at intervals after the upper end of the stirring shaft 402 penetrates into the immersion tank 1.

[0031] It should be noted that, in order to prevent the pearlescent pigment from being lost during the air drying process, in actual use, baffles (not shown in the figure) can be slidably installed on the inner walls of the drying chamber 2. When the hot air blower 501 is turned on for drying, the baffles can slide down and cover the through holes opened on the drying chamber 2 to prevent the pearlescent pigment from being blown away and immersed in the cracking oil again.

[0032] Furthermore, the intermittent mechanism includes a first transmission wheel 406, a complete gear 403, a first transmission belt 405, and a partial gear 404. The lower end of the stirring shaft 402 passes through the soaking tank 1 and is fixedly connected to the first transmission wheel 406 coaxially. The complete gear 403 is rotatably disposed on the outer wall of the soaking tank 1, and the partial gear 404 is connected to the output shaft of the first motor 401, and the complete gear 403 and the partial gear 404 are engaged in transmission. The first transmission belt 405 is driven between the first transmission wheel 406 and the complete gear 403.

[0033] It should be noted that because the outer circumference of the incomplete gear 403 is only partially toothed, when the incomplete gear 403 rotates once, it can only drive the complete gear 404 to rotate intermittently for a short time, thereby realizing the intermittent rotation of the stirring shaft 402.

[0034] Furthermore, the lifting assembly 3 includes a threaded rod 301, a second motor 302, a limiting rod 303, and a horizontal plate 304. The threaded rod 301 is rotatably mounted on the upper end of the soaking tank 1 in a vertical direction, and the output shaft of the second motor 302 is coaxially and fixedly connected to the threaded rod 301. A first moving block is also threadedly connected to the threaded rod 301. The limiting rod 303 is fixedly mounted on the upper end of the soaking tank 1 away from the threaded rod 301, and a second moving block is slidably mounted on the limiting rod 303. The horizontal plate 304 is fixedly mounted between the first moving block and the second moving block and is fixedly connected to the drying chamber 2.

[0035] It should be noted that in order to achieve the vertical movement of the drying oven 2, the second motor 302 is a bidirectional motor, and its output shaft can rotate clockwise and counterclockwise respectively.

[0036] Furthermore, a drying assembly 5 is also provided on the horizontal plate 304. The drying assembly 5 includes a hot air blower 501 and a ventilation mechanism. The hot air blower 501 is installed on the horizontal plate 304 and has multiple air outlets, each of which faces the inside of the drying chamber 2. The ventilation mechanism is connected to the air outlets of the hot air blower 501.

[0037] Furthermore, the air distribution mechanism includes a heat-resistant hose 502, a movable plate 503, and an eccentric wheel 504. The air outlet of the hot air blower 501 is connected to the heat-resistant hose 502. The movable plate 503 is slidably connected to the horizontal plate 304 in the transverse direction, and multiple openings are provided on the movable plate 503. The outlet end of the heat-resistant hose 502 passes through the openings one by one and faces the inside of the drying chamber 2. One end of the eccentric wheel 504 slides against the movable plate 503, and the eccentric wheel 504 is connected to the first motor 401 through the linkage mechanism 6.

[0038] It should be noted that the sliding connection between the movable plate 503 and the horizontal plate 304 can be specifically defined as a T-shaped groove and a T-shaped slider. The bottom of the horizontal plate 304 is provided with the T-shaped groove in the horizontal direction. The T-shaped slider is slidably installed in the T-shaped groove through a reset elastic element, and the T-shaped slider is fixedly connected to the movable plate 503.

[0039] Furthermore, the linkage mechanism 6 includes a rotating shaft 601, a second transmission wheel 602, a drive shaft 603, and a connecting assembly; the eccentric wheel 504 is rotatably connected to the horizontal plate 304 via the rotating shaft 601, and the second transmission wheel 602 is coaxially fixedly connected to the upper end of the rotating shaft 601 after passing through the horizontal plate 304; the drive shaft 603 is rotatably mounted on the outer wall of the soaking tank 1 in the vertical direction, and the drive shaft 603 is coaxially fixedly connected to the output shaft of the first motor 401, and the drive shaft 603 and the rotating shaft 601 are connected by the connecting assembly.

[0040] It should be noted that, through the aforementioned linkage mechanism 6, the first motor 401 drives the eccentric wheel 504 to rotate while simultaneously driving the stirring shaft 402 to rotate. However, at this time, the drying chamber 2 containing the pearlescent pigment has already separated from the pyrolysis oil, so even if the stirring shaft 402 rotates, it will not interfere with the drying of the pearlescent pigment. For practical use, operators can also set up a separate power source to drive the eccentric wheel 504 to rotate, such as a stepper motor.

[0041] Specifically, the connecting components in this embodiment include, but are not limited to, a transmission belt and a transmission wheel structure, which can synchronously drive the rotating shaft 601 and the drive shaft 603 to rotate; and the transmission between the drive shaft 603 and the incomplete gear 404 can be the same as the structure used between the complete gear 403 and the stirring shaft 402.

[0042] The implementation principle of this application embodiment is as follows: Pearl pigment is placed in drying oven 2, and the second motor 302 is started. The output shaft of the second motor 302 drives the threaded rod 301 to rotate in the forward direction, thereby driving the first moving block connected to its thread to move downward. Under the restriction of the second moving block and the limiting rod 303, the first moving block can finally drive the drying oven 2 to move vertically downward and enter the soaking tank 1 until the cracked oil flows into the drying oven 2 through the through hole to soak the pearl pigment. In order to accelerate the adsorption speed and improve the preparation efficiency, the operator turns on the first motor 40 at this time. 1. The output shaft of the first motor 401 drives the drive shaft 603 to rotate, which in turn drives the incomplete gear 404 to rotate. Only the toothed part of the incomplete gear 404 can mesh with the complete gear 403, so that the complete gear 403 can be driven to rotate intermittently. The first transmission belt 405 is sleeved between the first transmission wheel 406 and the complete gear 403. Under the transmission action, the complete gear 403 drives the stirring shaft 402 to rotate intermittently, so that the blades on the stirring shaft 402 rotate and stir intermittently at the bottom of the soaking tank 1, thereby accelerating the adsorption of organic matter.

[0043] When the preset soaking time is reached, the staff turns off the first motor 401 and turns on the second motor 302 again. The output shaft of the second motor 302 rotates in the opposite direction at this time, lifting the drying box 2 upward and separating it from the soaking box 1. Then, the hot air blower 501 is started for drying.

[0044] During drying, the operator can restart the first motor 401. The output shaft of the first motor 401 drives the drive shaft 603 to rotate, which in turn drives the second transmission wheel 602 and the rotating shaft 601 to rotate. This ultimately causes the eccentric wheel 504 to rotate. The eccentric wheel 504 alternately abuts against one side of the movable plate 503 with its long and short shaft ends, causing the movable plate 503 to slide left and right. This causes the outlet end of the heat-resistant hose 502 to swing back and forth, performing large-area uniform drying of the pearlescent pigment in the drying chamber 2. After drying, the pearlescent pigment is transferred to a high-temperature, low-oxygen environment for heating. At this time, the organic matter adsorbed on the surface of the pearlescent pigment decomposes and carbonizes, forming nano-carbon black particles. After cooling, cleaning, and other post-treatments, pearlescent pigment coated with nano-carbon black particles is obtained. This carbon layer is thin and uniform, with strong adhesion to the pearlescent surface, and is not easily detached during actual use.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
