Description

Technical Field

[0001] This utility model relates to the field of coating processing technology, and in particular to an intelligent mixing equipment for high-temperature resistant and anti-corrosion coatings. Background Technology

[0002] Paint is a viscous liquid that is applied to the surface of an object to be protected or decorated, and forms a continuous film that adheres firmly to the object. It is usually based on resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, and is prepared with organic solvents or water. There are many types of paint, and anti-corrosion and high-temperature resistant paint is one of them. In the production and processing of anti-corrosion and high-temperature resistant paint, a mixing and proportioning operation is required.

[0003] In the field of high-temperature resistant and anti-corrosion coating production, traditional mixing equipment mostly involves mixing multiple raw materials together and then stirring the mixture with a rotating stirring rod. During the stirring process, the raw materials are thrown onto the upper inner wall surface of the mixing tank due to centrifugal force. Since the proportions of the various materials are preset, the impact of some raw materials being thrown onto the inner wall affects the coating proportions. Furthermore, after the coating is mixed, its fluid properties result in a slow discharge rate, affecting processing efficiency. Therefore, we propose an intelligent mixing equipment for high-temperature resistant and anti-corrosion coatings. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent mixing device for high-temperature resistant and anti-corrosion coatings to solve the problems mentioned in the background art.

[0005] This application provides an intelligent proportioning device for high-temperature resistant and anti-corrosion coatings, including a proportioning box, a drive rod, and a scraping assembly. The proportioning box has a discharge component on its bottom surface, which communicates with the interior of the box. A drive component and multiple feeding assemblies are located on the top of the proportioning box. The output shaft of the drive component is coaxially connected to the drive rod, which is vertically positioned inside the proportioning box. Multiple stirring rods are symmetrically arranged on the drive rod. The scraping assembly is located inside the proportioning box and includes a wiping frame, a sliding block, and multiple support rods. The wiping frame is an annular frame, and its outer ring slides against the inner wall of the proportioning box. Multiple support rods are evenly arranged inside the wiping frame. Straight grooves are arranged along the axial direction on the drive rod, with the number of straight grooves matching the number of support rods. The support rods slide within their corresponding straight grooves, and the stirring rods are staggered from the support rods. A spiral groove is formed on the inner wall of the proportioning box, and a sliding block is provided on the outer wall of the wiping frame, slidingly embedded within the spiral groove.

[0006] Preferably, the internal space of the mixing tank is cylindrical, and the drive rod is coaxially arranged with the internal space of the mixing tank.

[0007] Preferably, the wiping frame is coaxially arranged with the drive rod, and the shortest distance between the stirring rod and the inner wall of the mixing tank is greater than the thickness of the wiping frame.

[0008] Preferably, the top surface of the wiping frame is a sloping surface with a higher outer ring and a lower inner ring.

[0009] Preferably, the sliding block is a horizontally arranged cylinder.

[0010] Preferably, the top end of the drive rod is rotatably mounted on the top inner wall of the mixing box via a bearing, and the output shaft of the drive component passes through the mixing box and is connected to the top end of the drive rod.

[0011] Preferably, the wiping frame is assembled from multiple arc-shaped frames connected by bolts, and the wiping frame is connected to the support rod by bolts.

[0012] Preferably, the feeding assembly includes a feeding box, a metering valve, and a feeding pipe; both the metering valve and the feeding pipe are installed at the bottom of the feeding box, and the feeding pipe is connected to the inside of the feeding box through the metering valve; the feeding pipe extends into the mixing tank.

[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages: The scraping assembly's annular wiping frame slides against the inner wall of the chamber, while the interior is slidably connected to the drive rod via a straight groove. An outer wall sliding block is embedded in a spiral groove on the inner wall of the chamber. During operation, the control unit coordinates the power assembly to drive the drive rod to rotate, which in turn drives the stirring rod to mix the raw materials. Simultaneously, the wiping frame rotates and rises and falls under the guidance of the spiral groove, scraping away any adhering materials from the chamber wall. This prevents the coating mixing ratio from being affected and improves processing efficiency. Attached Figure Description

[0019] Example: Figures 1 to 5 As shown, the intelligent proportioning equipment for the high-temperature resistant and anti-corrosion coating of this application includes a proportioning box 10, a drive rod 30, a scraping assembly 40, a power assembly, and a control unit.

[0020] The bottom of the mixing tank 10 is equipped with a support base 11.

[0021] The bottom surface of the mixing tank 10 is provided with a discharge component 13, and the discharge component 13 is connected to the interior of the mixing tank 10.

[0022] It should be noted that the discharge component 13 may include a discharge pipe and a discharge valve. The discharge valve controls whether to discharge and the discharge range. The discharge component 13 is a common structure in the prior art and will not be described in detail here.

[0023] Optionally, the discharge component 13 can be connected to an external pipeline (not shown in the figure) to draw the proportioned coating into a special container (not shown in the figure). This operation method is common in the prior art and will not be described in detail here.

[0024] The power component is used to supply power for the operation of the equipment, preferably an AC power source or a battery; the control unit is used to control the coordinated operation of the various components of the equipment, preferably a programmable logic controller; both are existing technologies and will not be described in detail here.

[0025] The top of the mixing tank 10 is equipped with a drive unit 12 and multiple feeding components 20.

[0026] The output shaft of the drive component 12 is coaxially connected to the drive rod 30, and the drive rod 30 is vertically arranged inside the proportioning box 10.

[0027] It should be noted that the top end of the drive rod 30 can be rotatably mounted on the top inner wall of the mixing box 10 via a bearing, and the output shaft of the drive component 12 passes through the mixing box 10 and is connected to the top end of the drive rod 30.

[0028] In addition, the internal space of the mixing tank 10 is cylindrical, and the drive rod 30 is coaxially arranged with the internal space of the mixing tank 10.

[0029] The driving component 12 can be a motor.

[0030] It should be noted that there may be 2, 3, 4, 5, or 6 feeding components 20, etc. The specific quantity and position distribution are selected according to actual needs, and will not be elaborated here.

[0031] Optionally, the top of the mixing tank 10 can be configured as an openable cover (not shown in the figure), or the side wall of the mixing tank 10 can be provided with a sealed door (not shown in the figure) to facilitate the cleaning and maintenance of the equipment. The openable cover structure and the sealed door are common structures in the prior art, and will not be described in detail here.

[0032] Multiple stirring rods 31 are symmetrically arranged on the drive rod 30.

[0033] Optionally, the stirring rod 31 is set horizontally.

[0034] It should be noted that there may be 6, 8, 10, 12, or 14 stirring rods 31, etc. The specific number and position distribution can be selected according to actual needs, which will not be elaborated here.

[0035] The scraping assembly 40 is located inside the mixing tank 10. The scraping assembly 40 includes a wiping frame 42, a sliding block 43, and multiple support rods 41.

[0036] The wiping frame 42 is an annular frame, and the outer ring of the wiping frame 42 slides against the inner side wall of the mixing box 10.

[0037] Specifically, the outer radius of the wiping frame 42 is the same as the radius of the internal space of the support base 11.

[0038] The wiping frame 42 is coaxially arranged with the drive rod 30, and the shortest distance between the stirring rod 31 and the inner wall of the mixing tank 10 is greater than the thickness of the wiping frame 42.

[0039] It should be noted that the thickness of the wiping frame 42 refers to the difference between the inner radius and the outer radius of the wiping frame 42; the shortest distance between the stirring rod 31 and the inner wall of the proportioning box 10 refers to the distance between the end of the stirring rod 31 away from the drive rod 30 and the inner wall of the proportioning box 10.

[0040] Multiple support rods 41 are evenly arranged inside the wiping frame 42, and the length direction of the support rods 41 is the same as the radial direction of the wiping frame 42.

[0041] It should be noted that there may be 2, 3, 4, 5, or 6 support rods 41, etc. The specific number and position distribution are selected according to actual needs, which will not be elaborated here.

[0042] The drive rod 30 is provided with a straight slide groove 32 along the axial direction. The number of straight slide grooves 32 is the same as that of the support rod 41 and they correspond one-to-one.

[0043] The support rod 41 is slidably disposed in the corresponding straight groove 32, and the stirring rod 31 is staggered from the support rod 41.

[0044] It should be noted that the straight slide groove 32 and the stirring rod 31 are staggered, so that the stirring rod 31 and the support rod 41 will not collide during the process of the support rod 41 sliding up and down along the straight slide groove 32.

[0045] The inner wall of the mixing box 10 is provided with a spiral groove 14, and the outer wall of the wiping frame 42 is provided with a sliding block 43, which is slidably embedded in the spiral groove 14.

[0046] It should be noted that the number of spiral grooves 14 can be one or more. When there are multiple spiral grooves 14, they do not interfere with each other and are evenly staggered along the axial direction of the stirring rod 31. In addition, the number of spiral grooves 14 and sliding blocks 43 are the same and correspond one-to-one. For example, if there are two spiral grooves 14 and the two spiral grooves 14 form a double spiral structure, then two sliding blocks 43 are symmetrically arranged on the outer ring of the wiping frame 42.

[0047] Optionally, a rubber ring may be provided around the outer edge of the wiping frame 42.

[0048] Optionally, the top surface of the wiping frame 42 is configured as a sloping surface with a higher outer ring and a lower inner ring.

[0049] It should be noted that the wiping frame 42 in this application can be assembled from multiple arc-shaped frames by bolt connection. The wiping frame 42 can also be connected to the support rod 41 by bolt connection, which facilitates disassembly, maintenance and replacement by relevant personnel.

[0050] Optionally, the sliding block 43 can be a horizontally positioned cylinder.

[0051] like Figure 2 As shown, in one embodiment of this application, the feeding assembly 20 includes a feeding box 21, a metering valve 22, and a feeding pipe 23.

[0052] The metering valve 22 and the feeding pipe 23 are both installed at the bottom of the feeding box 21, and the feeding pipe 23 is connected to the inside of the feeding box 21 through the metering valve 22.

[0053] The feeding pipe 23 extends into the mixing box 10.

[0054] Alternatively, the metering valve 22 can be a volumetric metering valve. The metering valve 22 is a common structure in the prior art. The specific type and model of the metering valve 22 can be selected according to actual needs, and will not be elaborated here.

[0055] It should be noted that the top surface of the mixing tank 10 has an opening corresponding to the feeding pipe 23, and the feeding pipe 23 extends into the mixing tank 10 through the opening.

[0056] Optionally, the top of the material feeding box 21 is provided with a box cover, which can be threaded onto the material feeding box 21 to facilitate material feeding by relevant personnel.

[0057] It should be noted that the stirring rod 31 in this application alternates between forward and reverse rotation during the stirring process, thereby driving the wiping frame 42 to move up and down alternately to assist in the mixing of the upper and lower layers of materials. In addition, according to common knowledge, the preparation of anti-corrosion coatings generally involves slow stirring combined with a staged speed adjustment strategy to ensure uniform dispersion of components while controlling bubble generation. Rapid stirring can easily introduce a large number of bubbles, leading to a decrease in coating density and affecting anti-corrosion performance. The number of turns of the spiral groove 14 in this application can be selected according to the application scenario to adapt to different stirring requirements; for example, if the stirring speed is 100 rpm, the number of turns of the spiral groove 14 can be selected from 10 to 15 turns. Figure 3 The diagram is for illustrative purposes only and does not specify the number of turns of the spiral groove 14.

[0058] In addition, alternating forward and reverse stirring can eliminate mixing dead zones, improve the uniformity of the coating, and reduce the overall rotation speed of the coating, thereby reducing the intensity of eddies and suppressing the formation of bubbles. At the same time, the short pauses when switching directions (such as reversing once every 30 seconds) allow formed bubbles to escape, which is especially suitable for coatings that are sensitive to bubbles (such as epoxy micaceous iron oxide intermediate paint). By alternating the shear direction, multi-directional impacts can be generated on solid particles, promoting their uniform suspension. For example, when formulating zinc-rich primer, alternating forward and reverse stirring can ensure that zinc powder particles are evenly dispersed, avoiding uneven internal stress in the coating caused by excessively high local concentrations.

[0059] Specifically, in actual operation, relevant personnel, according to the formula requirements, load the raw materials (such as resin, filler, curing agent, etc.) of different high-temperature resistant and anti-corrosion coatings into the discharge boxes 21 of each feeding component 20, and close the box lids; input the formula parameters (such as the amount of each raw material, stirring time, stirring speed, etc.) through the control unit (PLC), and the control unit opens the metering valves 22 of each feeding component 20 in sequence according to the preset ratio. The metering valves 22 precisely control the discharge amount through volumetric metering, and the raw materials fall into the mixing tank 10 through the discharge pipe 23.

[0060] When the drive unit 12 is activated, the drive rod 30 drives the stirring rod 31 to rotate in both directions, thoroughly mixing the raw materials in the mixing tank 10. During the rotation of the drive rod 30, the support rod 41 slides along the straight groove 32, while the sliding block 43 on the outer wall of the wiping frame 42 embeds into the spiral groove 14 on the inner wall of the mixing tank 10. Due to the spiral guiding effect of the spiral groove 14, the wiping frame 42 moves up and down along the drive rod 30 while rotating with it (similar to the principle of a screw lifting mechanism), achieving a motion of rotating and lifting simultaneously. As the wiping frame 42 moves up and down, its outer ring continuously scrapes the inner wall of the mixing tank 10, scraping the raw materials adhering to the tank wall back into the mixture, avoiding proportioning errors caused by raw material residue and improving mixing efficiency.

[0061] After mixing, the material is discharged through the discharge component 13. During the discharge process, the wiping frame 42 can continue to move to thoroughly remove the paint residue on the inner wall of the mixing tank 10, which is convenient for subsequent cleaning or direct entry into the next round of mixing.

[0062] It should be noted that the number of turns and pitch of the spiral groove 14 can be selected according to actual needs, and will not be elaborated here.

[0063] It should be explained that the intelligent proportioning device of this application can be converted into a normal use state during use: the user can remove the wiping frame 42, leaving only the support rod 41 in the proportioning box 10. At this time, the rotation speed and direction of the drive rod 30 in this application are not restricted.

[0064] Understandably, the drive rod 30 drives the stirring rod 31 to rotate, generating radial and axial fluid flow, which promotes uniform mixing of raw materials. The wiping frame 42, through the cooperation of the spiral groove 14 and the sliding block 43, combines rotational motion with up-and-down lifting motion, which not only promotes full vertical mixing of raw materials inside the proportioning box 10, but also ensures that the outer ring of the wiping frame 42 continuously contacts the inner wall of the box, scraping off the attached material and avoiding uneven mixing and residue. At the same time, the top surface of the wiping frame 42 is a sloping surface with a higher outer ring and a lower inner ring, which guides the scraped material to converge towards the center of the wiping frame 42, avoiding residue.

[0065] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
