Description

Technical Field

[0001] This application relates to the field of coating processing, and more specifically, to a self-mixing device for an organic material anti-deformation coating slurry. Background Technology

[0002] The self-mixing device for organic material anti-deformation coating slurry is an automated processing equipment for organic anti-deformation coating slurries. It can complete the proportioning and uniform mixing of various components of the slurry through a built-in stirring mechanism. It can also connect to subsequent feeding or coating processes to improve the mixing efficiency and consistency of the slurry and adapt to the needs of related material coating processing scenarios.

[0003] In response, Chinese patent application number 201621336836.X discloses a mixing device for processing coatings, including a base plate. A fixed hydraulic column and a hydraulic device are fixedly connected to the top of the base plate, and the bottom surface of the fixed hydraulic column is connected to one side of the hydraulic device. A telescopic column is slidably connected to the top of the fixed hydraulic column, and a top box is fixedly connected to the top of the telescopic column. A connecting shell is fixedly connected to one side of the bottom of the top box, and a motor is fixedly connected to the other side of the bottom of the top box. A connecting rod is fixedly connected to the motor's shaft. This mixing device for processing coatings solves the problem of relatively simple structures and inconvenient operation in current coating mixing equipment, making it more convenient for users, avoiding the problem of incomplete mixing, ensuring good mixing effect, achieving coatings that meet usage requirements, ensuring normal coating quality in the later stages, and reducing the economic costs for enterprises.

[0004] The above-mentioned solution also has the following shortcomings: the traditional paddle stirring method mainly causes the material to move in a circular direction when rotating. For materials such as organic material anti-deformation coating slurry, which is a mixture of multiple components, it is difficult to make the components fully dispersed and uniform. In addition, the anti-deformation coating has strong viscosity and is prone to clumping, resulting in inconsistent local component concentrations and affecting the performance of the slurry. Utility Model Content

[0005] To overcome the above deficiencies, this application provides a self-mixing device for organic material anti-deformation coating slurry, which aims to improve the problem that caking easily occurs when viscous materials are mixed, resulting in inconsistent local component concentrations and affecting the performance of the slurry.

[0006] This application provides a self-mixing device for an organic material anti-deformation coating slurry, including a support base for support and a mixing box on its top. The top of the mixing box is provided with a top cover plate with a feed inlet, and the bottom of the mixing box is provided with a discharge pipe. A spiral ribbon stirring structure with auxiliary dispersing components rotates inside the mixing box.

[0007] In one specific implementation, the ribbon-type stirring structure with auxiliary dispersing components includes a connecting rod rotatably connected to both ends of a mixing tank, wherein an mounting plate is provided on the inner side of the connecting rod, and a central shaft is threadedly connected to the mounting plate.

[0008] In the above implementation process, the threaded connection between the mounting plate and the central shaft facilitates the installation and disassembly of the central shaft, and also makes it convenient to replace the central shaft or mixing components of different specifications according to the characteristics of the slurry, thereby improving the flexibility and ease of maintenance of the device.

[0009] In one specific implementation, the surface of the central shaft is distributed with four symmetrically designed stirring plates, and the surface of the stirring plates is distributed with openings, in which a hollowed-out mesh frame is fixed.

[0010] In the above process, the symmetrically distributed stirring plates on the surface of the central shaft can be used to stir the slurry in the mixing tank laterally during rotation, breaking the static distribution of the slurry and promoting the initial mixing of raw materials. The openings on the surface of the stirring plates and the perforated mesh frame fixed inside the openings can break up the agglomerated slurry particles. At the same time, the slurry passes through the mesh frame during the stirring process, increasing the flow and collision of the slurry, further improving the dispersibility and mixing uniformity of the slurry, and avoiding the impact of particle agglomeration on the deformation resistance of the coating slurry.

[0011] In one specific implementation, a connecting rod is fixed to the surface of the central shaft within the gap of the stirring plate, wherein the surface of the connecting rod is surrounded by a helical ribbon, and the helical ribbon is provided in two sets with opposite spiral directions.

[0012] In the above process, the two sets of spiral ribbons with opposite directions can drive the slurry in the mixing tank to form a left-right convection motion when rotating, breaking the limitation of the slurry only stirring in the vertical direction, realizing the slurry to circulate and mix in the horizontal direction, improving the mixing efficiency and uniformity, and avoiding the formation of mixing dead zones in the tank.

[0013] In one specific embodiment, the spiral ribbon is wrapped around the stirring plate.

[0014] In the above process, the spiral ribbon is wrapped around the mixing plate, so that the convection mixing of the spiral ribbon and the lateral mixing of the mixing plate form a synergistic effect. When the spiral ribbon drives the slurry to circulate up and down, the mixing plate can further disperse and mix the circulating slurry. The two work together to expand the mixing coverage area and reduce the stratification or local unmixed phenomena of the slurry during the mixing process.

[0015] In one specific implementation, a drive motor is fixedly installed on one side of the mixing box, and the connecting rod at one end is fixedly connected to the output end of the drive motor.

[0016] In the above process, a drive motor provides a stable power source for the connecting rod, ensuring that the connecting rod drives the entire stirring structure to continuously mix.

[0017] In one specific implementation, a bearing bracket is provided on one side of the top cover plate, and a connecting bracket is provided on another side of the top cover plate, wherein the bearing bracket is rotatably connected to the surface of the connecting bracket.

[0018] In the above process, the bearing bracket on one side of the top cover plate is rotated and connected to the connecting frame, allowing the top cover plate to be flipped and opened around the connecting frame. This makes it easier for staff to open the top cover plate to clean and inspect the inside of the mixing tank, improving the ease of operation of the device.

[0019] In one specific implementation, the top layer of the mixing tank is provided with a C-shaped flip frame, wherein the top of the flip frame is provided with a threaded locking rod, and the top of the top cover plate is provided with a locking hole, wherein the threaded locking rod is inserted into the locking hole.

[0020] In the above process, the top cover plate is firmly fixed to the top of the mixing tank by the flipping frame to avoid the top cover plate from loosening or shifting due to the vibration caused by stirring during the mixing process, and to prevent the slurry from splashing from the gaps in the cover plate.

[0021] In one specific implementation, the bottom of the mixing box is provided with a discharge port connected to the feed pipe, wherein the bottom of the mixing box is provided with slide rails on both sides of the discharge port.

[0022] In the above implementation process, the slide rails on both sides of the discharge port provide sliding guidance for the baffle, ensuring that the baffle can accurately cover or leave the discharge port, thus preparing the structure for subsequent control of slurry discharge and avoiding the discharge port from being poorly sealed or unable to be fully opened due to the sliding displacement of the baffle.

[0023] In one specific implementation, the mixing box is further provided with a telescopic cylinder, wherein a telescopic rod is provided on one side of the telescopic cylinder, and a baffle is fixed to the extended end of the telescopic rod, wherein the baffle slides on the surface of the slide rail and covers the discharge port.

[0024] In the above process, the extension and retraction of the telescopic rod drives the baffle to slide along the slide rail, thereby realizing automatic opening and closing control of the discharge port. There is no need for manual operation of the baffle, which saves manpower and can accurately control the timing and amount of discharge, avoiding the waste of slurry or untimely discharge caused by manual operation delays, and improving the automation level of the device.

[0025] Compared with the prior art, the beneficial effects of this application are as follows:

[0026] 1. In this application, the stirring plate on the surface of the central shaft works in concert with two sets of counter-rotating spiral ribbons. The stirring plate can break up agglomerated particles and promote lateral mixing, while the counter-rotating spiral ribbons drive the slurry to form convection and achieve circulating mixing. The combination of the two reduces mixing dead zones, avoids slurry stratification or local unmixed areas, and ensures the uniformity of the organic material anti-deformation coating slurry, thus providing a guarantee for the anti-deformation performance of subsequent coatings.

[0027] 2. In this application, the discharge port is automatically controlled by a telescopic cylinder to drive the baffle, eliminating the need for manual operation; the central shaft can be quickly disassembled and replaced via the mounting plate. These designs reduce the intensity of manual intervention, shorten the time for cleaning, maintenance and discharge, improve overall work efficiency, and are suitable for batch slurry mixing needs.

[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0039] Please see Figure 1-8 This application provides a self-mixing device for an organic material anti-deformation coating slurry, including a support base 1 for supporting the overall weight of the device. The support base 1 is made of high-strength cast iron and has an anti-slip pad at the bottom to enhance friction with the ground and prevent the device from shifting due to vibration during mixing, thus ensuring overall stability. A mixing box 11 is fixedly installed on the top of the device by bolts. The mixing box 11 is a cylindrical box made of stainless steel and the inner wall is polished for easy cleaning.

[0040] A drive motor 12 is fixedly installed on one side of the mixing tank 11 via a motor bracket. The motor bracket is welded and fixed to the mixing tank 11 to ensure that the drive motor 12 is firmly installed. One end of the connecting rod 3 is fixedly connected to the output end of the drive motor 12 via a coupling. The drive motor 12 provides a stable and continuous power source for the connecting rod 3, ensuring that the connecting rod 3 drives the entire stirring structure to operate at a uniform speed, thus meeting the mixing requirements of anti-deformation coating slurries of organic materials with different viscosities.

[0041] The top of the mixing chamber 11 is equipped with a top cover plate 22 with a feed inlet 23. The top cover plate 22 is also made of stainless steel. The feed inlet 23 has a funnel-shaped structure, which facilitates the addition of raw materials into the mixing chamber 11. A bearing frame 21 is welded to one side of the top cover plate 22. The bearing frame 21 is a U-shaped metal frame with a deep groove ball bearing installed inside. A connecting frame 2 is fixed to one side of the top cover plate 22 by bolts. The connecting frame 2 is an L-shaped metal plate that is welded and fixed to the top edge of the mixing chamber 11. The bearing frame 21 is rotatably connected to the surface of the connecting frame 2 via a rotating shaft. The rotating shaft cooperates with the bearing inside the bearing frame 21, allowing the top cover plate 22 to be flexibly rotated and opened around the connecting frame 2. Through the rotational connection between the bearing frame 21 on one side of the top cover plate 22 and the connecting frame 2, the operator can open the chamber to clean or repair the inside of the mixing chamber 11 without completely disassembling the top cover plate 22, reducing the difficulty of operation and improving the convenience of device operation.

[0042] A C-shaped tilting frame 24 is welded to the outer top of the mixing tank 11. The top of the tilting frame 24 is threadedly connected to a threaded locking rod 25. The top of the threaded locking rod 25 is equipped with a knob for easy manual operation. A locking hole is opened at the corresponding position on the top of the top cover plate 22. The inner wall of the locking hole is provided with internal threads to match the threaded locking rod 25. When the top cover plate 22 is closed, the tilting frame 24 is tilted so that the threaded locking rod 25 is aligned with the locking hole on the top of the top cover plate 22. The knob is turned to screw the threaded locking rod 25 into the locking hole, which can firmly fix the top cover plate 22 to the top of the mixing tank 11. This prevents the top cover plate 22 from loosening or shifting due to vibration caused by the high-speed operation of the stirring structure during the mixing process, and effectively prevents the slurry from splashing from the gap between the cover plate and the tank body.

[0043] A discharge pipe 13 is welded to the center of the bottom of the mixing box 11. A discharge port is provided at the bottom of the mixing box 11 corresponding to the position of the discharge pipe 13. Slide rails are fixedly installed on both sides of the discharge port at the bottom of the mixing box 11 by bolts. The slide rails are made of stainless steel strip rails with chrome plating, which are smooth and wear-resistant. This reduces the frictional resistance when the baffle 43 slides. The slide rails on both sides of the discharge port provide precise sliding guidance for the baffle 43, ensuring that the baffle 43 remains horizontal during the sliding process and can accurately cover or leave the discharge port. This avoids the discharge port from being poorly sealed or unable to be fully opened due to the sliding deviation of the baffle 43, thus preparing the structure for subsequent precise control of slurry discharge.

[0044] A telescopic cylinder 4 is fixedly mounted on the outside of the mixing tank 11 via a cylinder bracket. The cylinder bracket is welded to the mixing tank 11 to ensure stable installation of the telescopic cylinder 4. A telescopic rod 41 is fixedly connected to the piston rod end of the telescopic cylinder 4. The telescopic rod 41 is a metal rod, and a baffle 43 is bolted to the extended end of the telescopic rod 41. The baffle 43 is an arc-shaped plate made of stainless steel with a diameter slightly larger than the discharge port diameter. A sealing gasket is provided at the bottom to enhance the sealing of the discharge port. Slider blocks are provided on both sides of the baffle 43. The sliders are adapted to the slide rail, allowing the baffle 43 to slide smoothly along the slide rail and accurately cover the discharge port. The telescopic cylinder 4 drives the telescopic rod 41 to extend and retract. The telescopic rod 41 extends, causing the baffle 43 to slide along the slide rail, thus achieving automatic opening and closing control of the discharge port. When the telescopic rod 41 extends, the baffle 43 moves along the slide rail toward the discharge port until it completely covers the discharge port, preventing the slurry from being discharged. When the telescopic rod 41 retracts, the baffle 43 moves away from the discharge port, opening the discharge port. The mixed slurry then enters the feed pipe 13 through the discharge port. This automatic control method eliminates the need for manual operation of the baffle 43, saving labor costs and enabling precise control of the discharge timing and volume through the control system. It can also be used in conjunction with a flow meter to avoid slurry waste or untimely discharge caused by manual operation delays, effectively improving the automation level of the device.

[0045] The mixing tank 11 contains a spiral ribbon stirring structure with auxiliary dispersing components, which is rotatably installed at both ends. The two ends are rotatably connected to the mixing tank 11 via bearing seats. The bearing seats contain seals to prevent slurry leakage. The spiral ribbon stirring structure with auxiliary dispersing components includes a connecting rod 3, which is a solid stainless steel rod. The connecting rod 3 is rotatably connected to both ends of the mixing tank 11 via bearing seats, which are fixed to the end covers of the mixing tank 11 to ensure stable operation of the connecting rod 3. The inner side of the connecting rod 3 is welded with mounting... The mounting plate 32 is a circular metal plate with evenly distributed threaded holes on its surface. The mounting plate 32 is internally threaded to a central shaft 31, which is made of stainless steel and has external threads that fit into the threaded holes of the mounting plate 32. Through the threaded connection between the mounting plate 32 and the central shaft 31, the operator can quickly install and remove the central shaft 31. When different types of slurry need to be mixed or when the mixing components are worn, it is easy to replace the central shaft 31 or the mixing components of different specifications, thus improving the flexibility and ease of maintenance of the device.

[0046] Four symmetrically designed stirring plates 33 are welded to the surface of the central shaft 31. The stirring plates 33 are rectangular stainless steel plates, and rectangular openings are evenly distributed on the surface of the stirring plates 33. A perforated mesh frame 34 is fixed to the opening with bolts. The mesh frame 34 is a square grid made of metal and is fixed to the edge of the opening. The stirring plates 33 symmetrically distributed on the surface of the central shaft 31 can longitudinally stir the slurry in the mixing box 11 when rotating, breaking the static distribution of the slurry and promoting the initial mixing between different raw materials. The openings on the surface of the stirring plates 33 and the perforated mesh frame 34 fixed in the openings can break up the agglomerated slurry particles. At the same time, the slurry passes through the mesh frame 34 during the stirring process, increasing the flow path of the slurry and the collision frequency between particles, further improving the dispersibility and mixing uniformity of the slurry, avoiding the decrease in the deformation resistance of the coating slurry due to particle agglomeration, and ensuring the quality of the final product.

[0047] A connecting rod 35 is welded and fixed to the surface of the central shaft 31 within the gap of the mixing plate 33. The connecting rod 35 is a short rod made of stainless steel and is radially distributed to ensure the fixing effect of the screw ribbon 36. The surface of the connecting rod 35 is surrounded by the screw ribbon 36, which is a spiral blade made of stainless steel. There are two sets of screw ribbons 36, located on the upper and lower sides of the central shaft 31 respectively, and the spiral directions of the two sets of screw ribbons 36 are opposite. Through the two sets of screw ribbons 36 with opposite spiral directions, the slurry in the mixing box 11 can be driven to form a left-right convection motion when rotating, breaking the limitation of the slurry being stirred only in the vertical direction, realizing the horizontal circulation mixing of the slurry, and improving the mixing efficiency and uniformity.

[0048] The screw ribbon 36 is wrapped around the mixing plate 33. By wrapping the screw ribbon 36 around the mixing plate 33, the convective mixing of the screw ribbon 36 and the lateral mixing of the mixing plate 33 form a synergistic effect. When the screw ribbon 36 drives the slurry to circulate left and right, the mixing plate 33 can further disperse and mix the slurry in the circulation process. The two work together to expand the mixing coverage area, so that the slurry in every part of the mixing box 11 can be fully mixed, reducing the stratification phenomenon or local unmixed phenomenon of the slurry during the mixing process, and ensuring that a uniform organic material anti-deformation coating slurry is finally obtained.

[0049] The working principle of the organic material anti-deformation coating slurry self-mixing device is as follows: First, the raw material of the organic material anti-deformation coating slurry is put into the mixing box 11 through the feed port 23 of the top cover plate 22. After the top cover plate 22 is closed, the threaded locking rod 25 is rotated by the flipping frame 24 on the top of the mixing box 11, so that it is inserted into the locking hole of the top cover plate 22 to lock the cover plate. The drive motor 12 on one side of the mixing box 11 is started, and its output end drives the connecting rotating rod 3 to rotate. The connecting rotating rod 3 drives the central shaft rod 31 to rotate synchronously through the inner mounting plate 32. The stirring plate 33 on the surface of the central shaft rod 31 stirs and disperses the slurry. At the same time, the connecting rod 35 on the central shaft rod 31 drives two sets of opposite spiral ribbons 36 to rotate. The ribbons 36 surround the stirring plate 33 to further promote the mixing of the slurry. After the mixing is completed, the telescopic cylinder 4 on the outside of the mixing box 11 is started. Its telescopic rod 41 drives the baffle 43 to slide along the slide rails on both sides of the bottom discharge port of the mixing box 11, opening the discharge port. The mixed slurry enters the discharge pipe 13 through the discharge port and is discharged, completing the entire mixing operation.

[0050] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
