Description

Technical Field

[0001] The present invention relates to the technical field of paint mixing kettles, and particularly to a paint mixing kettle with high-speed dispersion. Background Art

[0002] The paint mixing kettle is the core equipment for material mixing, dispersion and reaction in industries such as coatings, inks, adhesives, etc. Traditional paint mixing processes rely on manual stirring or simple mechanical devices, which have problems such as low mixing uniformity, poor batch stability, and high energy consumption. With the development of industrial automation and intelligence, modern paint mixing kettles integrate multi-axis stirring systems, variable frequency speed regulation technology, precise temperature control, and intelligent sensing devices, which can achieve efficient shear dispersion and uniform mixing of materials.

[0003] Application No. CN202420202240.9 applied for a reaction kettle for latex paint modulation, including a reaction kettle body. A motor is fixedly connected to the top of the reaction kettle body. The output end of the motor is fixedly connected to a rotating shaft. One end of the rotating shaft is fixedly connected with a number of blades. The bottom of the reaction kettle body is communicated with a discharge cylinder. One side of the top of the reaction kettle body is communicated with a feed box. When the cover plate moves downward, the cover plate will squeeze the sliding rod, causing the rotating plate to rotate, driving the connecting rod to move, thereby pulling the convex block, so that the blanking plate placed above the convex block drops. In this way, when the cover plate is closed, the blanking plate will drop at the same time. In this way, the gas generated after adding the raw materials will disperse in the reaction kettle body. By setting the cover plate, when pouring the powder raw materials from the feed box, the cover plate is opened, and the push ring will drive the blanking plate to move, making the blanking plate lie flat. In this way, the powder raw materials will fall on the surface of the blanking plate. And when the blanking plate moves, it will squeeze the convex block, so that the convex block will not hinder the movement of the blanking plate.

[0004] According to the above technical solution, it is found that when stirring paint, adjacent pigment particles contact each other and bond during stirring, and the bonded pigment particles are not easily dissolved in the paint liquid and remain in the paint for a long time. This will cause the paint to be not easily stirred evenly. In addition, since the weight of the bonded pigment particles changes, and the pigment particles with larger particle size will sink to the bottom layer of the paint liquid, resulting in the situation of paint stratification, causing the problem that the pigment particles cannot be evenly dissolved in the paint liquid.

[0042] In summary, during use, first pour the material to be stirred into the interior of the paint mixing kettle body 202 through the feed pipe 201, then set appropriate rotation speeds for the driving assembly 1 and the temperature during the operation inside the paint mixing kettle body 202, and then the paint inside the paint mixing kettle body 202 can be mixed and stirred. When the stirring work is completed, just open the control valve to allow the paint to enter the interior of the filter chamber 402, and after filtration, it can be discharged to the outside through the discharge pipe 401.

[0043] The driving component 1 drives the rotating shaft 102 by turning on the driving motor 101, which will drive the control panel 1051 to rotate, and the driving rod 1052 on the control panel 1051 to rotate. With the rotation of the driving rod 1052, the mixing plate 1053 is cooperated to stir and mix the paint inside the paint mixing kettle main body 202. According to the amount of paint inside the paint mixing kettle main body 202, the electronic spring can be started to drive the sliding sleeve 1055 to slide along the surface of the rotating shaft 102, so that the angle of the control rod 1054 changes, and the driving rod 1052 is controlled by the control rod 1054 to extend outwards. When the elongation of the control rod 1054 increases, the purpose of increasing the stirring area is achieved. During the process of stirring the paint, the water spray pipe located near the top of the rotating shaft 102 can be controlled to spray water into the paint mixing kettle main body 202, which can quickly reduce the dust of the particles inside the paint mixing kettle main body 202.

[0044] When the paint mixing and stirring work is completed, at this time, by opening the control valve at the bottom of the inner wall of the paint mixing kettle main body 202, the paint inside the paint mixing kettle main body 202 will directly enter the filter chamber 402. When the paint enters the filter chamber 402, it will first contact one end of the discharge pipe 401. Since a filter screen is provided at one end of the discharge pipe 401, when the paint enters the discharge pipe 401 through the filter chamber 402, it will be intercepted by the filter screen, and the impurity particles inside the paint will be further filtered, so as to ensure the quality of the paint after discharging. When the paint passes through the filtration of the filter screen, it will directly flow into the other end of the discharge pipe 401 for discharging.

[0045] It should be noted that: the sliding sleeve 1055 is connected to the end of the electronic spring, and the electronic spring is fixedly arranged on the surface of the rotating shaft 102. By turning on the electronic spring and using the contraction and elongation of the electronic spring to control the sliding sleeve 1055 to slide up and down along the outer surface of the rotating shaft 102. When the electronic spring is not in the working state, the flexible tube 111 is in the initial state (not in the compressed state). When the electronic spring is in the working state, the sliding sleeve 1055 is controlled to slide along the outer surface of the rotating shaft 102, and at the same time the flexible tube 111 is in the compressed state. At the same time, two electronic springs are provided on the outer surface of the rotating shaft 102, which are respectively connected to the upper and lower sliding sleeves 1055.

[0046] Second Embodiment In the first embodiment, when stirring the paint, adjacent pigment particles come into contact with each other and adhere during stirring. After adhesion, the pigment particles are not easily dissolved in the paint liquid and remain inside the paint for a long time. This can make it difficult to stir the paint evenly. In addition, since the weight of the adhered pigment particles changes, the larger pigment particles will sink to the bottom layer of the paint liquid, resulting in paint stratification and the problem of not being able to evenly dissolve the pigment particles in the paint liquid. Based on this, the present invention proposes a second embodiment and makes the following adjustment plan: During the process of stirring the paint inside the paint mixing kettle body 202, the particle size of the pigments inside the paint is detected by an optical sensor, and it is judged whether the pigment particles precipitate and form stratification based on the particle size of the pigment particles.

[0047] In addition, the model of the optical sensor is a laser particle size analyzer, which can emit multiple laser beams to the outside and determine the size and distribution of the pigment particles by detecting the intensity and angular distribution of the scattered light.

[0048] When the optical sensor does not detect that there are particles inside the paint at this time, and it also does not detect that there is pigment precipitation at the bottom of the paint mixing kettle body 202 through the angular distribution of the emitted light, it indicates that the pigments inside the paint have been fully dissolved in the paint. At this time, only the paint needs to be stirred and mixed to make the color distribution inside the paint uniform, and no adjustment is made.

[0049] Under the transmission of the drive motor 101, when controlling the rotation shaft 102 and the stirring plate 1053 to rotate and stir the paint in the paint mixing kettle body 202, the optical sensor detects the particles inside the paint. If the optical sensor detects that there are pigment particles inside the paint at this time and the detected pigment particle size is large, the following adjustments are made at this time: First, by controlling the drive motor 101 to increase its rotational speed, the rotational speed of the rotating shaft 102 will increase significantly at this time. During this process, due to the increase in the rotational speed of the rotating shaft 102, and in cooperation with the control panel 1051, the drive rod 1052, and the stirring plate 1053, the inside of the paint mixing kettle body 202 is stirred. Under the high-speed rotation of the rotating shaft 102, the rotational speed of the stirring plate 1053 increases. At this time, when the stirring plate 1053 contacts the particles in the paint, it will impact the surface of the pigment particles, and cooperate with the rotating shaft 102 to crush the pigment particles inside the paint, so that they can be quickly dissolved and dispersed. Due to the increase in the rotational speed of the rotating shaft 102, the centrifugal force generated will cause the sliding block 1057 inside the stirring plate 1053 to slide along the surface of the sliding rod 1056. When the sliding block 1057 slides along the sliding rod 1056 to the lower surface of the inner wall of the stirring plate 1053, one side of the sliding block 1057 will exert a squeezing force on the right side of the blade 1058. Under the centrifugal force and the gravity of the sliding block 1057 itself, the blade 1058 is pushed to slide inside the stirring plate 1053, and the cutting surface of the blade 1058 slides out of the stirring plate. At this time, in cooperation with the stirring action of the stirring plate 1053, the pigment particles in the paint are cut, preventing the pigment particles from being too large and not easily dissolving and dispersing, and at the same time avoiding causing pigment precipitation and resulting in paint stratification.

[0050] After the above adjustment scheme, if the optical sensor detects that there are no pigment particles in the paint at this time and the pigment distribution in the paint is uniform, it means that the above adjustment is effective at this time, and the drive motor 101 is controlled to return to the initial power, so that the rotating shaft 102 returns to the initial rotational speed. When the rotational speed decreases, the sliding block 1057 will quickly reset under the action of the second return spring. When the sliding block 1057 leaves, the blade 1058 will quickly slide into the inside of the stirring plate 1053 under the action of the first return spring, so as to return to the initial state as a whole and continue to stir and mix the paint inside the paint mixing kettle body 202, preventing damage caused by high temperature generated by too high power.

[0051] If the optical sensor detects that the pigment particles in the paint still exist and detects through the angular distribution of the light emitted that the pigment particles in the paint are distributed at the bottom of the paint mixing kettle body 202, it means that the pigment particles have precipitated at this time. The following adjustment steps are taken at this time: First, turn on the electronic spring to control the sliding sleeve 1055 to slide along the surface of the rotating shaft 102, causing the control rod 1054 to rotate, reducing the angle between the control rod 1054 and the rotating shaft 102, and causing the driving rod 1052 to extend outwards. In this way, the driving rod 1052 will drive the stirring plate 1053 to rotate, increasing the area of the stirring plate 1053 during stirring. In addition, when the electronic spring controls the sliding sleeve 1055 to slide, the flexible tube 111 will be in a compressed state. At this time, the paint liquid inside the flexible tube 111 will quickly squeeze outwards from the mesh holes on the surface of the limiting column 110. Since there is some gas inside the flexible tube 111, the squeezed paint liquid and gas will enter the bottom of the paint mixing kettle body 202 at the same time, and destroy the adhesion state of the paint stratification tension. In this way, the pigment particles at the bottom of the paint mixing kettle body 202 will be scattered. Since the discharged gas and liquid blow the pigment particles to the area near the stirring plate 1053 close to the bottom end of the rotating shaft 102, control the micro-motor to deflect the stirring plate 1053. When the stirring plate 1053 is in a deflected state, it will lift the pigment particles in the paint upwards, and then quickly control the micro-motor to make the stirring plate 1053 rotate along the outside of the driving rod 1052, and control the rotation direction of the stirring plate 1053 to be opposite to the rotation direction of the rotating shaft 102. The stirring plate and the blade continuously break the pigment particles to prevent the pigment particles from settling at the bottom of the paint mixing kettle body 202 again.

[0052] It should be noted that when the compression tube 111 is stretched, it will be in a negative pressure state inside, and suck the liquid in the paint mixing kettle through the connecting tube 112. Since the connecting tube 112 is set in a one-way valve mode that only allows entry but not exit, when the compression tube 111 is compressed, the pressure inside it will increase, and the liquid will enter the inside of the rotating shaft 102 through the feed hole on the rotating shaft 102, and enter the inside of the limiting column 110 through the discharge hole, and finally spray outwards through the one-way valve located inside the limiting column 110. When the compression tube 111 returns to its original position, it sucks the liquid in the paint mixing kettle again through the connecting tube 112 on its surface, thus returning to the initial state. If the optical sensor detects that the pigment particles in the paint are still present, and detects through the angle distribution of the emitted light that the pigment particles in the paint are still at the bottom of the paint mixing kettle body 202, then the electronic spring is controlled to make the sliding sleeve 1055 slide downward to compress the compression tube 111, so that the compression tube 111 is in a fully compressed state, so that the liquid inside the compression tube 111 is discharged through the one-way valve on one side of the limit column 110. At the same time, due to the sliding process of the sliding sleeve 1055, the control rod 1054 extends the driving rod 1052. When the driving rod 1052 is extended to the maximum limit, the dispersion plate 1054 is in a state of being fully compressed. The cutting knife 1058 on 053 will contact one side of the first cleaning rod 108 and the second cleaning rod 109, and apply thrust to the first cleaning rod 108 and the second cleaning rod 109, so that they rotate along the inner wall of the paint mixing kettle body 202, thereby achieving the effect of scraping the inner wall of the paint mixing kettle body 202. At the same time, the micro motor is controlled to rotate the dispersion plate 1053 located at the bottom of the rotating shaft 102, and the rotation direction of the dispersion plate 1053 is opposite to the direction of the rotating shaft 102, and a turbulent flow is formed, thereby achieving the effect of crushing the scraped pigment particles and scraping and crushing the pigment particles adhering to the inside of the paint mixing kettle body 202.

[0053] It is worth noting that the internal one-way valve of the limit column 110 and the connecting pipe 112 are both one-way valves, and the specific working process of the compression tube 111 is that when the compression tube 111 is in a compressed state, the liquid inside it will first enter the rotating shaft 102, and flow from the inside of the rotating shaft 102 to the inside of the limit column 110, and then discharge the liquid toward the bottom area of ​​the paint mixing kettle body 202 through the internal one-way valve. When the compression tube 111 is not in a stressed state, the sliding sleeve 1055 located on the upper and lower surfaces of the rotating shaft 102 will generate pulling force on the upper and lower ends of the compression tube 111 when it is reset. At this time, the compression tube 111 will absorb liquid through the connecting pipe 112 to reset.

[0054] In addition, the compression tube 111 is made of elastic material. When the sliding sleeve 1055 does not apply pressure to the compression tube 111, the compression tube 111 will be reset in cooperation with the reset of the sliding sleeve 1055. When the compression tube 111 is not subjected to force and returns to its initial state, the compression tube 111 absorbs the liquid in the paint mixing kettle through the connecting tube 112, so that the internal pressure of the compression tube 111 is in a normal state, thereby avoiding the situation where the compression tube 111 is too slow in efficiency when absorbing gas and liquid by itself, resulting in low reset efficiency of the compression tube 111, and the pigment at the bottom of the paint mixing kettle body 202 cannot be kept in a floating state.
