Description

Technical Field

[0001] This utility model belongs to the field of anti-corrosion coating production technology, specifically relating to a high-speed dispersion device for anti-corrosion coating production. Background Technology

[0002] In the field of anti-corrosion coating production, the raw material system typically includes key components such as resins, pigments, fillers, solvents, and additives. Among these, resins, as film-forming substances, are one of the core components determining the performance of anti-corrosion coatings. Common types include epoxy resins, polyurethane resins, and acrylic resins. However, in the low-temperature environment of winter, the physical properties of resin raw materials undergo significant changes. Due to the reduced activity of molecular chain segments, the viscosity of the system increases significantly, exhibiting a viscous state.

[0003] In the industrial production of anti-corrosion coatings, high-speed dispersers are the core equipment for achieving uniform dispersion of raw materials. They generate strong shear force through a high-speed rotating dispersion disc, promoting thorough mixing of the components. However, when the viscosity of the resin raw materials increases in winter, the drive system of the high-speed disperser must withstand a greater torque load, easily leading to problems such as drive motor overload, accelerated wear of transmission components, and even equipment shutdown, severely impacting production efficiency and stability. Existing dispersion devices typically use movable stainless steel mixing drums, which allow for convenient cleaning and unloading. However, the accompanying heating structures are mostly fixed designs (such as wound electric heating belts and jacketed heat transfer oil circulation structures). These heating components cannot be disassembled or folded for storage in non-winter conditions, resulting in a redundant and complex overall structure of the mixing drum, increasing the difficulty of cleaning and maintenance (e.g., material residue can easily remain in the gaps of the heating elements, creating dead corners). Furthermore, the space occupied by the fixed heating components makes it difficult to store the equipment compactly when idle.

[0004] To address the aforementioned technical problems, this utility model proposes a high-speed dispersion device that combines heating function to prevent the viscosity of anti-corrosion coating raw materials from becoming too high due to low temperatures, and also features a foldable storage structure to adapt to production needs in different seasons. This represents a key technical direction for solving the problem of overload in winter production, improving equipment space utilization and ease of operation. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed dispersion device for anti-corrosion coating production, comprising a base, a lifting column installed on one side of the base, a dispersion mechanism installed at the top of the lifting column, a cylinder placed on the other side of the base, a circular guide rail provided at the top of the cylinder, guide rail grooves being provided on the surface of the base on the outer side of the cylinder and at the bottom of the circular guide rail, the two guide rail grooves being collinearly arranged, folded strips being evenly installed between the two guide rail grooves, and hinge shafts being installed between adjacent folded strips. In two adjacent folded strips, the two ends of the hinge shafts at both ends respectively form a sliding fit with the two guide rail grooves. The hinge shafts located between the two folded strips only maintain the pivotal connection between adjacent plates. Electric heating rods are evenly fixed on the inner side of the hinge joint of the folded strips.

[0006] As a preferred technical solution of this utility model, a slide is fixed at both the top and bottom of the hinge shaft, and an installation cavity is opened inside the slide, with a ball bearing installed inside the installation cavity.

[0007] As a preferred embodiment of the present invention, the lifting column includes a column body, the bottom end of the column body is fixedly connected to a base, a hydraulic cylinder is fixed inside the column body, and a housing is fixed to the output end of the hydraulic cylinder.

[0008] As a preferred technical solution of this utility model, the dispersing mechanism includes a drive motor and a rotating shaft. The top end of the rotating shaft is rotatably connected to one end of the housing. A dispersing disc is fixed at the bottom end of the rotating shaft. The output shaft of the drive motor and the top end of the rotating shaft are connected by a belt and a pulley.

[0009] As a preferred embodiment of this utility model, the circular guide rail is welded with support rods on both sides, the column body is fixed with a buckle, and the other end of the support rod is fixed to the buckle.

[0010] As a preferred embodiment of this utility model, a temperature controller is fixed on one side of the column body, and the temperature controller is electrically connected to the electric heating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) This utility model utilizes the cooperation between the guide rail groove and the hinge shaft through the folded strip plate, and the electric heating rod installed on the inner side can be quickly unfolded to form a cylindrical heating layer surrounding the cylinder. Compared with the traditional fixed heating belt, it can raise the resin raw material in the cylinder from a low temperature to the required process temperature in a shorter time, which significantly reduces the viscosity of the raw material, avoids the drive motor from overloading and stopping when the dispersion disc rotates at high speed, and improves the continuity of production in winter.

[0013] (2) Adjacent folding strips form a hinge structure through "interval hinge shafts". When the heating structure is unfolded, each folding strip unfolds synchronously and maintains flatness to ensure heating uniformity. When folded, the folding strips are stacked and contracted along the guide rail groove, greatly reducing the overall thickness and saving workshop floor space.

[0014] (3) The movable stainless steel cylinder combined with the foldable heating structure completely solves the problem of easy material accumulation in the gaps of traditional fixed heating elements. When cleaning is required, simply retract the folding strips and remove the cylinder. There are no protruding parts, and it can be directly rinsed without dead angles using a high-pressure water gun or automatic cleaning machine. The cleaning time is greatly shortened and the maintenance efficiency is significantly improved. Attached Figure Description

In two adjacent folding strips 6, the two ends of the hinge shafts 7 respectively form a sliding fit with the two guide rail grooves 5. The hinge shafts 7 located between the two folding strips 6 only maintain the pivotal connection between the adjacent plates. Electric heating rods 8 are evenly fixed on the inner side of the hinge joint of the folding strips 6.

[0024] In order to reduce the frictional resistance when the folding strip 6 slides and improve the smoothness of unfolding or folding operations, in this embodiment, as a preferred technical solution of the present invention, the top and bottom ends of the hinge shaft 7 are fixed with slide seats 9, the slide seats 9 have an installation cavity 10 inside, and the installation cavity 10 is equipped with ball bearings 11.

[0025] In order to achieve adjustable vertical height of the dispersing mechanism and adapt to the dispersing operation requirements of cylinders 3 with different volumes, in this embodiment, as a preferred technical solution of the present invention, the lifting column 2 includes a column body 12, the bottom end of the column body 12 is fixedly connected to the base 1, a hydraulic cylinder 13 is fixed inside the column body 12, and a housing 14 is fixed at the output end of the hydraulic cylinder 13.

[0026] In order to provide a stable high-speed shear force field and ensure the uniform dispersion of anti-corrosion coating raw materials, in this embodiment, as a preferred technical solution of the present invention, the dispersion mechanism includes a drive motor 15 and a rotating shaft 16. The top end of the rotating shaft 16 is rotatably connected to one end of the housing 14, and a dispersion disk 17 is fixed at the bottom end of the rotating shaft 16. The output shaft of the drive motor 15 and the top end of the rotating shaft 16 are connected by a belt and a pulley.

[0027] In order to fix the spatial position of the circular guide rail 4 and prevent the heating structure from shaking when not in operation, in this embodiment, as a preferred technical solution of the present invention, support rods 18 are welded on both sides of the circular guide rail 4, and buckles 19 are fixed to the column body 12, with the other end of the support rod 18 fixed to the buckle 19.

[0028] In order to achieve precise temperature control during the heating process and prevent the raw materials from deteriorating due to overheating, in this embodiment, as a preferred technical solution of the present invention, a temperature controller 20 is fixed on one side of the column 12, and the temperature controller 20 is electrically connected to the electric heating rod 8.

[0029] In summary, the core working principle of this utility model, based on the above-described technical solution, is as follows:

[0030] Heating module deployment and temperature control under winter operating conditions:

[0031] When entering a low-temperature production environment during winter, the operator pulls the end of the folding strip 6 with external force, unfolding the folding strip 6 around the hinge shaft 7. At this time, the folding strip 6, through the ball bearings 11 inside the slide seat 9, achieves low-resistance operation during the unfolding / retraction process, smoothly extending along the upper and lower guide rail grooves 5 into a cylindrical shape to wrap around the cylinder 3, forming a cylindrical heating structure surrounding the outside of the cylinder 3. After the electric heating rod 8 unfolds with the folding strip 6, its heating surface is in close contact with the outside of the cylinder 3, and it heats the resin and other raw materials inside the cylinder 3 at a constant temperature through heat conduction, maintaining the raw material temperature within a preset range, ensuring that the activity of the resin molecular chain segments is enhanced and the viscosity is reduced to the range required by the dispersion process.

[0032] Power transmission in distributed mechanisms:

[0033] The hydraulic cylinder 13 inside the lifting column 2 can drive the housing 14 to rise and fall vertically, thereby adjusting the height of the rotating shaft 16 and the lower dispersion disc 17 to the center position of the cylinder 3. The drive motor 15 drives the rotating shaft 16 to rotate at high speed through a belt drive system, and the dispersion disc 17 generates a strong shear force field, which rapidly disperses and mixes the heated low-viscosity resin with pigments, fillers, solvents and other components. Since the viscosity of the raw material is controlled within a reasonable range through heating, the load torque of the drive motor 15 is significantly reduced, avoiding overload protection shutdown and wear of transmission components.

[0034] Folding and storage in non-winter working conditions:

[0035] When the ambient temperature rises back to normal (≥15℃) and continuous heating is no longer required, the operator pushes the end of the folding strip 6, which forms a strip structure, in the opposite direction, causing the folding strip 6 to fold and retract along the two guide grooves 5. The hinge shaft 7 drives the folding strip 6 to rotate around the pivot connection point, ultimately resulting in a stacked state. The folded electric heating rod 8 is then retracted and detached from the outside of the cylinder 3, facilitating adjustments to the workshop production line layout and equipment maintenance.

[0036] Finally, it should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components.
