Description

Technical Field

[0001] The invention relates to the technical field of production of colored protective road paving paint, and in particular to a two-component colored anti-skid road paving paint production device and production process. Background Art

[0002] Green environmentally friendly colored anti-skid road paving paint is a kind of paint with special properties and environmental protection characteristics.

[0003] The main advantages of this coating include:

[0004] 1. Environmental protection: Usually adopts a formula with low volatile organic compounds to reduce potential harm to the environment and human health.

[0005] 2. Anti-slip performance: It can effectively increase the friction of the road surface and improve the driving safety of pedestrians and vehicles on the road.

[0006] 3. Rich colors: Various bright colors can be mixed according to needs to beautify the road environment and improve traffic signs.

[0007] 4. Durability: It has good wear resistance, weather resistance and chemical corrosion resistance, and can maintain its performance and appearance for a long time.

[0008] In terms of application, it is widely used in urban roads, highways, bicycle paths, pedestrian walkways, etc. Its construction process is relatively simple.

[0009] However, the current green and environmentally friendly colored anti-skid road paving coatings need to reduce the content of bubbles as much as possible during the production and preparation process. A large amount of bubbles will greatly reduce the adhesion performance of the coating to the road surface, affecting the service life of the coating. Therefore, during the preparation process, the paving coating needs to be defoamed, and the current defoaming methods are mechanical defoaming and chemical defoaming. Mechanical defoaming is to eliminate bubbles by mechanical crushing, while chemical defoaming is to eliminate bubbles with a defoaming agent. However, the use of defoaming agents will affect the composition of the paving coating and will also pollute the environment.

[0010] In a Chinese patent with patent application number 2020116320541, an anti-peeling, environmentally friendly, colored, non-slip pavement and a preparation method thereof are disclosed. During the preparation process, stirring is performed under constant temperature and speed with vacuum treatment until no bubbles are generated.

[0011] In the Chinese patent application number 2024104012035, a raw material stirring device for paint and coating production is disclosed. When the material is stirred and mixed, the barrel cover is driven up by the driving member to form a negative pressure environment inside the outer barrel body. In the process of the material flowing from the upper part of the inner barrel body to the inner barrel body and the outer barrel body, since the distance between the bubbles and the material is very small at this time, the negative pressure environment can make the upward movement and rupture of the bubbles in the process smoother, thereby making the elimination of bubbles more efficient. As the bubbles rupture one after another, the negative pressure environment in the outer barrel body will disappear.

[0012] Although negative pressure exhaust can eliminate bubbles in the material faster and more actively than ordinary stirring treatment, when preparing paving paint, due to the adhesion of the paving paint itself, the effect of using negative pressure exhaust technology to break the bubbles is not ideal.

[0013] Therefore, there is an urgent need for an efficient and environmentally friendly defoaming method that can be improved on the basis of negative pressure exhaust and is suitable for the preparation of colorful environmentally friendly two-component paving coatings. Summary of the invention

[0014] In view of the above problems, the present invention provides a two-component colored anti-skid road paving coating production device and production process, which adjusts the internal air pressure of the reaction chamber by compressing an airbag, cooperates with a lifting device to exhaust the flat flow of the mixture, uses a bubble scraper to scrape and concentrate the overflowing liquid bubbles, and uses an exhaust device to perform centralized bubble crushing and exhaust treatment to achieve the purpose of mechanical bubble crushing, thereby removing the gas in the liquid bubbles and retaining the liquid.

[0021] The exhaust device is installed on the outer side wall of the reactor, and is connected to the bottom of the outer bin and the top of the inner bin. After the exhaust device sucks the liquid bubbles, it performs mechanical bubble crushing to remove the gas, and then circulates the liquid mixture back to the inner bin.

[0022] As an improvement, a plurality of stirring paddles for rotary stirring are arranged in the inner bin, and the stirring paddles are arranged at equal distances around the central axis of the inner bin.

[0023] As an improvement, the lifting device is a spiral lifting structure, which includes an external lifting cylinder and internally rotatably arranged spiral lifting blades.

[0024] As an improvement, the diverter fin is arranged in the form of an inclined circular ring, and a fin is arranged on the outer end surface of the diverter fin.

[0025] As an improvement, a rotating drum is mounted on the top of the inner bin, and a plurality of groups of bubble scrapers are arranged in a circular array and mounted on the annular direction of the rotating drum, and the bubble scrapers rotate synchronously with the rotating drum.

[0026] As an improvement, the bubble scraper includes a connecting pipe and a bubble scraper blade;

[0027] The connecting pipe is arranged along the radial direction of the rotating cylinder, an opening for accommodating the entry of liquid bubbles is arranged at the end of the connecting pipe located inside the rotating cylinder, and a discharge port for discharging liquid bubbles is arranged on the bottom plate of the end of the connecting pipe located outside the rotating cylinder;

[0028] The bubble scraping blade is rotatably installed in the connecting pipe, and the bubble scraping blade self-rotates to scrape liquid bubbles from the opening.

[0029] As an improvement, the exhaust device includes a circulation pipe, a circulation pump and a mechanical bubble breaking component;

[0030] The circulation pipe is connected with the bottom of the outer chamber and the top of the reaction chamber;

[0031] The circulation pump draws liquid bubbles at the bottom of the outer bin through the circulation pipe;

[0032] The mechanical bubble-breaking component is arranged on the path where the liquid bubbles are sucked and circulated, and the mechanical bubble-breaking component breaks and exhausts the liquid bubbles.

[0033] As an improvement, the mechanical bubble crushing assembly includes a bubble crushing box, a bubble crushing blade and an exhaust valve;

[0034] The foam crushing box is installed on the circulation pipe, and the foam crushing blade is rotatably installed in the foam crushing box, and the foam crushing holes are evenly distributed on the blades of the foam crushing blade;

[0035] The exhaust valve is installed on the top of the bubble crushing box. The exhaust valve is a one-way valve that exhausts the gas generated in the bubble crushing box.

[0036] As an improvement, a liquid separator assembly is provided at the end of the circulation pipe communicating with the top of the reaction chamber, and the liquid separator assembly disperses the liquid generated after the bubble is broken onto the diverter fins.

During the production of component A and component B in the two-component color anti-skid road paving paint, the two-component color anti-skid road paving paint production device is used for mechanical defoaming treatment.

[0038] The beneficial effects of the present invention are:

[0039] (1) In the process of preparing the components A and B of the paving coating, the present invention uses negative pressure technology to enable the gas in the mixture to be quickly released to the liquid surface during the preparation process, and at the same time cooperates with the flow dispersion of the lifting device to release the bubbles from the inside of the mixture more quickly, and then collects and transfers the bubbles on the liquid surface by scraping, and finally breaks and releases the concentrated bubbles by mechanical pressure, thereby achieving a fast, efficient and green defoaming treatment;

[0040] (2) The present invention uses mechanical defoaming to quickly defoam components A and B. Compared with the existing mechanical defoaming, the defoaming speed and efficiency are better. The gas generated during the defoaming process is directly discharged to the outside of the outer bin through the exhaust valve on the top of the bubble crushing box, and will not have any impact on the mixture in the outer bin. The quality of the paving paint produced is better.

[0041] (3) When the bubble scraper scrapes the bubbles on the liquid surface of the inner bin from the inner bin to the outer bin, the mixture in the inner bin is still rotated and stirred, and the vortex generated by the rotation and stirring lifts and disperses the mixture more smoothly through the lifting device, so that the mixture can be quickly spread, and the mixture can be exchanged up and down, so that the gas inside the mixture can be dispersed more quickly, thereby improving the gas removal efficiency;

[0042] (4) The present invention provides a liquid separator assembly at the discharge end of the circulation pipe, and utilizes the liquid separator assembly to evenly disperse the reactants circulating in the circulation pipe. At the same time, when mixing the materials of component A or component B, the exhaust device and the liquid separator assembly can cooperate to achieve dripping of the mixture, and at the same time, even mixing of the components can be achieved. In addition, the edge of the rotating liquid separator plate in the liquid separator assembly is connected to the diversion fin, so that the mixture lifted by the lifting device is evenly mixed with the material output by the liquid separator, and the mixing and dispersion effect is more excellent.

[0043] In summary, the present invention has the advantages of high defoaming efficiency, fast speed, green and environmentally friendly prepared paving coating, uniform mixing and dispersion of various components, and high quality of paving coating. It is particularly suitable for the production technology field of paving coating involving colored protective roads. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0065] Embodiment 1:

[0066] like Figure 1-Figure 6 As shown, a two-component color anti-skid road paving paint production device includes a reactor 1, a reaction chamber 100 is arranged in the reactor 1, and an inner chamber 11 and an outer chamber 12 are separated in the reaction chamber 100;

[0067] The colored anti-skid road paving coating production device also includes a lifting device 3, a compressed air bag 4, a bubble scraper 5 and an exhaust device 6;

[0068] The lifting device 3 is disposed at the center of the inner bin 11, and the lifting device 3 lifts the mixture at the bottom of the inner bin 11 to the diverter fins 30 at the top of the inner bin 11 for flat flow and exhaust;

[0069] The compressed air bag 4 is arranged on the top of the reactor 1, and the compressed air bag 4 expands and contracts to adjust the air pressure in the reaction chamber 100;

[0070] The bubble scraper 5 is disposed on the top of the inner bin 11, and the bubble scraper 5 scrapes the bubbles on the liquid surface of the inner bin 11 and transfers them to the bottom of the outer bin 12;

[0071] The exhaust device 6 is installed on the outer wall of the reactor 1, and the exhaust device 6 connects the bottom of the outer bin 12 and the top of the inner bin 11. After the exhaust device 6 sucks the liquid bubbles, it performs mechanical bubble crushing to remove the gas, and then circulates the liquid mixture back to the inner bin 11.

[0072] The lifting device 3 includes a lifting cylinder 31 and a spiral lifting blade 32;

[0073] like Figure 4 As shown, the lifting cylinder 31 is fixedly installed at the central axis of the inner bin 11, and a notch 311 is opened at the lower edge of the lifting cylinder 31. The notch 311 cooperates with the bottom of the inner bin 11 to form a feed port 312. The mixture enters the lifting cylinder 31 from the feed port 312. The splitter fin 30 is installed at the upper edge of the lifting cylinder 31. The splitter fin 30 is slightly higher than the top of the lifting cylinder 31, and the lifting cylinder 31 is slightly higher than the height of the liquid level inside the inner bin 11. The splitter fin 30 and the lifting cylinder 31 are made of corrosion-resistant, high-temperature-resistant, and smooth-surfaced ceramic materials.

[0074] The spiral lifting blade 32 is rotatably installed in the lifting cylinder 31. The spiral lifting blade 32 is made of corrosion-resistant and high-temperature resistant iron-based alloy material. The spiral lifting blade 32 is driven to rotate by the motor 33 arranged on the top of the reactor 1, and a spiral groove 321 is formed between the spiral lifting blade 32 and the side wall of the lifting cylinder 31. The spiral lifting blade 32 rotates, so that the mixture is continuously squeezed upward through the spiral groove 321 and dispersed through the diverter fin 30. Since the diverter fin 30 can spread a thin layer of the mixture, the gas inside the mixture is more likely to overflow to form liquid bubbles.

[0075] Furthermore, the diverter fin 30 is arranged in an inclined circular ring, and a plurality of groups of fins 301 are arranged on the outer end surface of the diverter fin 30. The fins 301 are arranged along the inclined direction of the diverter fin 30. The purpose of arranging the fins 301 is to make the mixture gradually thinner along the fan-shaped area when it is spread flat.

[0076] In addition, if Figure 6-Figure 8 As shown, a rotating cylinder 111 is rotatably provided at the top of the inner warehouse 11, and a groove is provided at the lower end of the rotating cylinder 111, which just fits with the upper edge of the inner warehouse 11, so that the rotating cylinder 111 is mounted on the top of the inner warehouse 11, and a circular ring plate is provided on the outer ring of the rotating cylinder 111, and the edge of the circular ring plate just fits with the inner wall of the outer warehouse 12, so that the rotating cylinder 111 can rotate on the top of the inner warehouse 11, and the rotating cylinder 111 just separates the outer warehouse 12 and the inner warehouse 11.

[0077] The rotating cylinder 111 cooperates with the transfer gear 101 at the lower end of the rotating shaft 10 through the first gear ring 112 arranged on the top, and the top of the rotating shaft 10 is connected to the spiral lifting blade 32 through the gear set 102, so that the rotating cylinder 111 rotates synchronously with the rotation of the spiral lifting blade 32, and is arranged in a circular array on the annular direction of the rotating cylinder 111. As the rotating cylinder 111 rotates around the spiral lifting blade 32, the liquid surface on the liquid surface of the inner chamber 11 is scraped.

[0078] The second gear ring 113 arranged at the bottom of the rotating cylinder 111 is connected to the gear transmission at the top of the stirring paddle 114 installed in the inner warehouse 11. The stirring paddles 114 are arranged in a circle equidistantly around the central axis of the inner warehouse 11. The stirring paddles 114 are rotatably installed on the inner wall of the inner warehouse 11 through connecting parts, and the stirring paddles 114 rotate and stir with the rotation of the rotating cylinder 111. The rotation of the stirring paddles 114 just allows the mixture between the inner warehouse 11 and the lifting cylinder 31 to enter the lifting cylinder 31, and enhances the ability of the spiral lifting blades 32 to lift the mixture.

[0079] Embodiment 2:

[0080] With reference to Example 1, the difference between Example 2 of the present invention and Example 1 is described as follows:

[0081] like Figure 7-10 As shown, the bubble scraper 5 includes a connecting pipe 51, a bubble scraper blade 52 and a rotating gear 53;

[0082] The connecting tube 51 is arranged along the radial direction of the rotating cylinder 111, and an opening 511 is arranged on the side wall of the end of the connecting tube 51 located inside the rotating cylinder 111, and a drainage port 512 is arranged on the bottom plate of the end of the connecting tube 51 located outside the rotating cylinder 111. The liquid bubbles on the liquid surface inside the inner bin 11 enter the connecting tube 51 through the opening 511, and are discharged to the outer bin 12 through the drainage port 512. The bottom plate of the connecting tube 51 is slightly lower than the liquid surface of the inner bin 11, so that the liquid bubbles can be scraped into the inner bin 11, and when the rotating cylinder 111 rotates, it is preferred to drive the connecting tube 51 to rotate toward the side where the opening 511 is arranged.

[0083] The bubble scraping blade 52 is rotatably installed in the connecting pipe 51. When the bubble scraping blade 52 rotates, the bubbles at the opening 511 are continuously scraped into the connecting pipe 51. Due to the continuous rotation of the bubble scraping blade 52, the bubbles entering the connecting pipe 51 are just blocked from escaping the connecting pipe 51 again. The bubble scraping blade 52 continuously rotates, so that the bubbles continuously enter and are discharged from the discharge port 512.

[0084] The rotating gear 53 is rotatably mounted on the rotating shaft of the scraping blade 52. The rotating gear 53 is located above the discharge port 512. The rotating gear 53 is meshed with a third gear ring 54 fixedly mounted at the edge of the rotating cylinder 111. When the rotating cylinder 111 rotates, the scraping blade 52 is driven to rotate by the cooperation between the rotating gear 53 and the third gear ring 54. When the scraping blade 52 rotates by itself, it rotates from top to bottom to scrape the bubbles on the liquid surface into the connecting tube 51.

[0085] Embodiment 3:

[0086] With reference to Embodiment 1-2, the difference between Embodiment 3 of the present invention and Embodiment 1-2 is described as follows:

[0087] like Figure 11-Figure 14 As shown, the exhaust device 6 includes a circulation pipe 61, a circulation pump 62 and a mechanical bubble breaking component 63;

[0088] The circulation pipe 61 connects the top and bottom of the outer chamber 12, and the liquid bubbles at the bottom of the outer chamber 12 are sucked through the circulation pipe 61;

[0089] The circulation pump 62 is installed on the circulation pipe 61, and the circulation pump 62 sucks the liquid bubbles at the bottom of the outer chamber 12 through the circulation pipe 61;

[0090] The mechanical bubble breaking component 63 is installed on the circulation pipe 61 from the circulation pump 62 to the bottom of the outer bin 12 , and the mechanical bubble breaking component 63 is arranged lower than the circulation pump 62 .

[0091] Furthermore, the mechanical bubble crushing assembly 63 includes a bubble crushing box 631, a bubble crushing blade 632, a bubble crushing motor 633, an exhaust valve 634, an exhaust ejector pin 635 and a pressure gauge 630;

[0092] The bubble crushing box 631 is installed on the circulation pipe 61, and the bubble crushing blade 632 is rotatably installed in the bubble crushing box 631. The bubble crushing holes 636 are evenly distributed on the blades of the bubble crushing blade 632. The top of the bubble crushing box 631 is installed with a bubble crushing motor 633 that drives the bubble crushing blade 632 to rotate;

[0093] The exhaust valve 634 is installed on the top of the bubble crushing box 631, and the exhaust valve 634 is a one-way valve;

[0094] The exhaust pin 635 is vertically disposed on the top of the exhaust valve 634, and the exhaust pin 635 is inserted into the exhaust valve 634 to open the exhaust valve 634 for exhaust;

[0095] The pressure gauge 630 is installed on the bubble crushing box 631 , and detects the air pressure in the bubble crushing box 631 and controls the exhaust pin 635 to open the exhaust valve 634 .

[0096] The circulation pump 62 extracts the liquid bubbles at the bottom of the outer chamber 12 through the circulation pipe 61, so that the liquid bubbles enter the bubble crushing box 631. Since the connection part of the circulation pipe 61 connecting the bubble crushing box 631 and the outer chamber 12 is located at the top of the bubble crushing box 631, and the circulation pipe 61 connecting the circulation pump 62 and the bubble crushing box 631 is located at the bottom, the liquid bubbles entering the bubble crushing box 631 are first mechanically crushed by the bubble crushing blade 632, and then the gas is released. The gas is located in the upper layer of the bubble crushing box 631, and the lower layer is The liquid mixture is then returned to the inner chamber 11 through the circulation pipe 61 and the circulation pump 62, while the gas continues to accumulate. As the amount of gas accumulation continues to increase, the gas pressure measured by the pressure gauge 630 will also become larger and larger, until the pressure measured by the pressure gauge 630 reaches a preset value, and the exhaust pin 635 is manually or electrically controlled to squeeze the valve core of the exhaust valve 634 under the drive of the lifting cylinder, so that the exhaust valve 634 opens, and the accumulated gas in the bubble box 631 is discharged from the exhaust valve 634.

[0097] It should be emphasized here that the horizontal position of the mechanical bubble crushing component 63 of the present invention is lower than the circulating pump 62. After the liquid bubbles are transported to the inside of the bubble crushing box 631, they will be quickly crushed by the bubble crushing blades 632, so that the air in the liquid bubbles is discharged. In addition, the bubble crushing box 631 is also provided with a pipe connected to the inner warehouse 11 to transport the initial liquid mixture inside the bubble crushing box 631 and replenish the liquid mixture inside the bubble crushing box 631 during the bubble crushing process, so that a part of the liquid mixture is always retained in the bubble crushing box 631. During the operation, cavitation of the circulating pump 62 can be avoided to maintain the normal operation of the circulating pump 62.

[0098] Furthermore, by externalizing the mechanical bubble breaking component 63, the bubble breaking will not affect the negative pressure in the outer chamber 12, so that the gas overflow in the outer chamber 12 can be continuously maintained, and the gas impurities in the mixture can be removed more thoroughly.

[0099] Embodiment 4:

[0100] With reference to Examples 1-3, the difference between Example 4 of the present invention and Examples 1-3 is described as follows:

[0101] like Figure 15-16 As shown, the top of the circulation pipe 61 communicating with the outer chamber 12 is provided with a liquid distributor assembly 65, and the liquid distributor assembly 65 includes a circular infusion head 651 and a rotating liquid distributor plate 652;

[0102] The annular infusion head 651 is fixedly arranged around the spiral lifting blade 32, and the annular infusion head 651 includes a main pipe 6511, a liquid discharge nozzle 6512 and a liquid separation wheel 6513. The main pipe 6511 is arranged in an annular shape, and the main pipe 6511 is connected to the circulation pipe 61. A plurality of liquid discharge nozzles 6512 are arranged equidistantly along the annular path of the main pipe 6511, and the liquid discharge nozzles 6512 are inclined from the main pipe 6511 to the circulation pipe 61. The center of the main pipe 6511 is provided, and the liquid separator wheel 6513 is provided at the center of the main pipe 6511. The circumferential side wall of the liquid separator wheel 6513 is provided with liquid receiving holes 6514 which are arranged one by one corresponding to the liquid discharge nozzles 6512. The liquid receiving holes 6514 receive the mixture output by the liquid discharge nozzles 6512, and guide the mixture to the center of the liquid separator wheel 6513, and discharge the mixture to the liquid separator plate 652 through the through hole at the bottom of the liquid separator wheel 6513.

[0103] The rotating liquid separation plate 652 is arranged in an inclined circular ring shape, and the rotating liquid separation plate 652 is installed on the spiral lifting blade 32, and the rotating liquid separation plate 652 is arranged to rotate synchronously with the spiral lifting blade 32. The rotating liquid separation plate 652 is located below the liquid separation wheel 6513, and the rotating liquid separation plate 652 rotates to disperse the mixture output by the liquid separation wheel 6513.

[0104] It should be noted that, through the dispersion setting of the liquid separator assembly 65, the input material can be evenly dispersed, and the outer edge of the rotating liquid separator plate 652 is connected to the diverter fin 30. The material dispersed by the rotating liquid separator plate 652 just falls on the uppermost end of the diverter fin 30, and the material is evenly mixed along the slope of the diverter fin 30. When preparing components A and B, the preparation of the mixture can have a good effect of uniform mixing and proportioning. When breaking the bubbles, the mixture after breaking the bubbles can be well and evenly dispersed into the inner bin 11 through the liquid separator assembly 65.

[0105] Embodiment 5:

[0106] like Fig.17 As shown, referring to Examples 1-4, a production process of a two-component colored anti-skid road paving coating according to Example 5 of the present invention is described, comprising the following steps:

[0117] The steps a1, a2 and steps b1, b2 all adopt mechanical defoaming treatment, and the mechanical defoaming treatment steps include:

[0118] c1. The mixture to be defoamed is spirally conveyed upward through the lifting device 3 in the reactor 1, so that the mixture is conveyed upward from the bottom of the inner bin 11 of the reactor 1 to the top of the inner bin 11, and the mixture flows obliquely downward from the diverter fins 30 on the top of the lifting device 3 to disperse, so that the mixture can form a thin material layer on the diverter fins 30, and then the gas inside the mixture can be quickly dissipated to form liquid bubbles on the surface of the material layer. Since the gas forms liquid bubbles on the material layer, the liquid bubbles are retained on the liquid surface at the top of the inner bin 11 during the process of gradually flowing downward along the diverter fins 30;

[0119] c2. Synchronously with step c1, the compressed air bag 4 arranged on the top of the reactor 1 is stretched, so that negative pressure is formed in the reactor 1. The gas in the mixture flowing and dispersed on the diverter fins 30 floats on the surface of the mixture in the form of liquid bubbles. Since the reactor 1 has been vacuumed at the beginning, the compressed air bag 4 can smoothly form negative pressure in the reactor 1 after being stretched, so that the gas quickly overflows from the mixture to form liquid bubbles on the liquid surface. The compressed air bag 4 is driven to compress or stretch by the cylinder installed on the top of the outer chamber 12. The bottom of the compressed air bag 4 is connected to the outer chamber 12. The outer chamber 12 is connected, and at least one group of the compressed airbags 4 is provided. Since the reactor 1 has been vacuumed, the atmospheric pressure received by the outside of the compressed airbags 4 is relatively large, and it needs to be driven by a cylinder or a hydraulic cylinder to stretch and compress. The compressed airbags 4 are metal corrugated pipes that can be compressed and stretched and sealed. While having the characteristics of stretching and compression, they also have a certain rigidity and will not be squeezed and deformed by the atmospheric pressure. The compressed airbags 4 are only connected to the outer chamber 12, but not to the outside world. After the compressed airbags 4 are stretched, the space becomes larger, thereby forming a lower negative pressure in the inner chamber 11.

[0120] c3. The mixture carries bubbles along the diverter fins 30 and flows to the liquid surface between the inner bin 11 and the lifting device 3. The bubble scraper 5 arranged on the liquid surface rotates to scrape the bubbles on the liquid surface, so that the bubbles are transferred to between the outer bin 12 and the inner bin 11 of the reactor 1. When the bubble scraper 5 is working, the bubbles on the liquid surface of the inner bin 11 are gradually scraped into the bubble scraper 5, and then the bubbles are concentrated in the space between the outer bin 12 and the inner bin 11 through the bubble scraper 5.

[0121] c4. The exhaust device 6 is arranged outside the reactor 1, and sucks the bubbles between the outer warehouse 12 and the inner warehouse 11 from the bottom of the outer warehouse 12 and circulates them to the top of the outer warehouse 12 and discharges them into the inner warehouse 11. During the circulation process, the bubbles are broken by mechanical extrusion to discharge the gas. After the bubbles are concentrated, the bubbles also contain a mixture. Therefore, after the bubbles are extracted by the exhaust device 6, they are concentrated for mechanical bubble crushing. After the bubbles are broken, the gas is released, and the retained liquid is circulated to the inner warehouse 11 again through the exhaust device 6 to participate in the preparation. The prepared component A or component B material is discharged through the discharge pipe at the bottom of the inner warehouse 11, and the discharge pipe extends out of the outer warehouse 12.

[0122] According to the "Determination of Volatile Organic Compound Release in Coatings" (GB / T37884-2019), the gas residue of the mixture after mechanical defoaming treatment of the present invention and the mixture after existing mechanical defoaming treatment and chemical defoaming treatment is measured. The measurement results are shown in Table 1 below:

[0123] Table 1

[0124]

[0125] It can be seen from Table 1 that the gas residual amount of the mixture after mechanical defoaming treatment of the present application is much smaller than the gas residual amount of the mixture after the existing mechanical defoaming treatment, and is also very close to the gas residual amount of the mixture after chemical defoaming treatment. Therefore, the mechanical defoaming treatment technology of the present application is far superior to the existing mechanical defoaming treatment technology. At the same time, because the effect of the chemical defoaming treatment technology is similar, it can also reduce the use of chemical defoaming agents, which is more environmentally friendly and green.

[0126] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
