Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a matte masterbatch mixing device for preventing agglomeration. Background Technology

[0002] In industries such as plastics processing and coatings, matting masterbatch is a key functional masterbatch for achieving a matte finish on material surfaces. Its production and processing require stringent requirements for uniformity and anti-caking properties in the mixing process. Matting masterbatch is typically made by mixing resin carriers, matting agents, and other additives. If the mixing is uneven or the temperature is not properly controlled during the mixing stage, particle agglomeration and clumping can easily occur. This not only reduces the dispersibility of the matting masterbatch but also directly affects the matting effect and appearance quality of subsequent products. Industrially used matting masterbatches have specific temperature requirements for the mixing process. Suitable temperatures can reduce the viscosity of the resin carrier, improve material flowability, and help reduce clumping; excessively low temperatures can lead to poor material flowability, hindering mixing and causing clumping; excessively high temperatures may cause premature softening and adhesion of the resin.

[0003] Chinese Patent CN215447236U discloses an anti-caking matting masterbatch stirring device, which includes: a storage box adapted to store matting masterbatch; a stirring mechanism disposed within the storage box and adapted to stir the matting masterbatch within the storage box; a vibration mechanism disposed on the outer wall of the storage box and adapted to drive the storage box to vibrate; and a control module electrically connected to the stirring mechanism and the vibration mechanism, the control module being adapted to control the stirring mechanism to stir the matting masterbatch within the storage box and to control the vibration mechanism to drive the storage box to vibrate, thereby preventing the matting masterbatch from agglomerating and thus avoiding a decrease in the matting masterbatch effect and quality due to agglomeration.

[0004] However, there is still room for improvement in this patented technology: although it uses a vibration mechanism to assist in preventing agglomeration, it does not optimize the design for temperature control required for mixing matting masterbatch, lacks a structure that can achieve uniform heat transfer and low-loss insulation, and cannot improve material flowability through temperature regulation to assist in preventing agglomeration; at the same time, its stirring mechanism does not adopt a multi-dimensional stirring design, and the stirring coverage of materials in different areas of the tank is still insufficient, making it difficult to completely solve the problem of local agglomeration caused by mixing dead corners.

[0005] Therefore, developing a mixing device for anti-caking and matting masterbatch with integrated functions of multi-dimensional stirring, uniform heating, and low-loss heat preservation has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing an anti-caking matting masterbatch stirring device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A matting masterbatch mixing device for preventing caking includes a mixing tank, a mixing assembly is provided inside the mixing tube, the mixing assembly includes a rotating mixing element and a vertical mixing element, and a heat jacket is provided on the outer wall of the mixing tank.

[0009] The heat jacket is a hollow structure, and a guide plate is provided inside the heat jacket. The guide plate has a spiral structure and is evenly wrapped around the outer periphery of the mixing tank. An inflow pipe is provided at one end of the heat jacket and is connected to the heat jacket. An outflow pipe is provided at the bottom of the heat jacket, and an insulation layer is provided on the outer periphery of the heat jacket.

[0010] Preferably, the rotating stirring component includes a rotary motor, which is disposed at the top of the stirring tank. A stirring rod is disposed inside the stirring tank, and the output end of the rotary motor movably penetrates through the outer wall of the stirring tank and is connected to the stirring rod.

[0011] Preferably, the stirring rod is provided with a plurality of blades, and the blades are integrally formed with the stirring rod.

[0012] Preferably, the vertical stirring component includes a pushing component, the output end of the pushing component is provided with a telescopic rod, a plurality of horizontal rods are provided on one side of the telescopic rod, and a stirring rod is provided through the horizontal rods.

[0013] Preferably, the pushing component is a push rod motor.

[0014] Preferably, the insulation layer is a vacuum insulation structure.

[0015] Preferably, the mixing tank is made of a thermally conductive material.

[0016] Preferably, the outer wall of the mixing tank is provided with a discharge port.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention utilizes a combination of rotating and vertical stirring components within the mixing tank to create a multi-dimensional stirring effect. This covers different radial and vertical areas within the tank, eliminating dead zones and preventing particle agglomeration of components such as resin carriers and matting agents due to uneven mixing. It also breaks up existing micro-clumps, ensuring uniform material dispersion and reducing the risk of clumping. The hollow structure of the heat jacket accommodates the heating medium and transfers heat to the tank wall, regulating the temperature of the material inside to reduce resin carrier viscosity and improve material flowability. Furthermore, the guide plates within the spiral structure of the heat jacket guide the heating medium along a pre-set path, preventing localized stagnation and ensuring the heat jacket's stability. The uniform temperature of the mixing tank wall prevents materials from clumping due to localized low temperatures or sticking due to high temperatures. The insulation layer around the heat jacket effectively blocks heat transfer to the external environment, maintaining a stable temperature of the heating medium and ensuring that the materials remain within a suitable mixing temperature range to avoid clumping caused by temperature fluctuations. It also reduces heat loss to lower the energy consumption of the equipment. The above-mentioned mixing, heating, and insulation components work together to construct a multi-dimensional integrated functional system of mixing, uniform heating, and low-loss insulation. This significantly improves the mixing uniformity of matting masterbatch, effectively inhibits clumping, and ensures the stability of equipment operation and energy utilization efficiency, meeting the core requirements of matting masterbatch production for the mixing process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-3A matting masterbatch mixing device for preventing agglomeration includes a mixing tank 1, a mixing assembly is provided inside the mixing tank 1, the mixing assembly includes a rotating mixing element 2 and a vertical mixing element 3, and a heat jacket 4 is provided on the outer wall of the mixing tank 1.

[0025] The heat jacket 4 has a hollow structure. A guide plate 5 is provided inside the heat jacket 4. The guide plate 5 has a spiral structure and is uniformly wrapped around the outer periphery of the mixing tank 1. An inflow pipe 6 is provided at one end of the heat jacket 4 and is connected to the heat jacket 4. An outflow pipe 7 is provided at the bottom of the heat jacket 4, and a heat insulation layer 8 is provided on the outer periphery of the heat jacket 4.

[0026] In the example of this application, the present invention, by setting the rotating stirring component 2 and the vertical stirring component 3 in the mixing tank 1 to cooperate, forms a multi-dimensional stirring action, covering different radial and vertical areas inside the tank to eliminate stirring dead zones. This not only avoids particle agglomeration of components such as resin carrier and matting agent due to uneven mixing, but also breaks up existing micro-clumps, ensuring uniform material dispersion and reducing the risk of agglomeration. The hollow structure of the heat jacket 4 can accommodate the heating medium and transfer heat to the wall of the mixing tank 1, adjusting the temperature of the material inside the tank to reduce the viscosity of the resin carrier and improve the flowability of the material. In addition, the guide plate 5 of the spiral structure inside the heat jacket 4 can guide the heating medium to flow orderly along a preset path, avoiding local stagnation. This ensures uniform temperature between the heating jacket 4 and the wall of the mixing tank 1, preventing materials from clumping due to localized low temperatures or sticking due to high temperatures. The insulation layer 8 around the heating jacket 4 effectively blocks heat transfer to the external environment, maintaining a stable temperature of the heating medium and ensuring that the materials remain within a suitable mixing temperature range to avoid clumping caused by temperature fluctuations. It also reduces heat loss to lower the energy consumption of the equipment. The above-mentioned stirring, heating, and insulation components work together to construct a multi-dimensional integrated functional system of stirring, uniform heating, and low-loss insulation, significantly improving the stirring uniformity of matting masterbatch, effectively suppressing clumping, and ensuring the stability of equipment operation and energy utilization efficiency, thus meeting the core requirements of matting masterbatch production for the stirring process.

[0027] In the example of this application, the rotating stirring component 2 includes a rotating motor 12, which is disposed at the top of the stirring tank 1. A stirring rod 13 is disposed inside the stirring tank 1, and the output end of the rotating motor 12 movably passes through the outer wall of the stirring tank 1 and is connected to the stirring rod 13.

[0028] As a preferred example of this utility model, by placing the rotary motor 12 at the top of the mixing tank 1, with its output end movably penetrating through the outer wall of the mixing tank 1 and connected to the stirring rod 13 inside the tank, this structure enables the rotary motor 12 to directly transmit power to the stirring rod 13. This results in low power loss and high transmission efficiency, and can stably drive the stirring rod 13 to rotate around its own axis inside the mixing tank 1. This, in turn, creates a horizontal stirring effect on the matting masterbatch inside the tank, causing the matting masterbatch to generate circumferential motion inside the tank. This effectively prevents the masterbatch from accumulating locally inside the tank, laying the foundation for subsequent anti-caking.

[0029] In the example of this application, the stirring rod 13 is provided with a plurality of blades 14, and the blades 14 are integrally formed with the stirring rod 13.

[0030] As a preferred example of this utility model, a plurality of blades 14 are provided on the stirring rod 13 and the blades adopt an integral molding structure. On the one hand, the arrangement of the plurality of blades 14 can significantly increase the contact area between the stirring rod 13 and the matte masterbatch, improve the coverage of the stirring action, make the masterbatch more uniformly stressed during the stirring process, reduce the local agglomeration phenomenon caused by insufficient stirring, and further enhance the anti-caking effect. On the other hand, the integral molding design of the blades 14 and the stirring rod 13 can greatly improve the connection strength and structural stability of the two, prevent the blades 14 from falling off or breaking due to stress during the stirring process, and ensure the long-term reliable operation of the stirring assembly.

[0031] In the example of this application, the vertical stirring component 3 includes a pushing component 15, the output end of the pushing component 15 is provided with a telescopic rod 16, a plurality of horizontal rods 17 are provided on one side of the telescopic rod 16, and a stirring rod 18 is provided through the horizontal rods 17.

[0032] As a preferred example of this utility model, the vertical stirring component 3 drives the telescopic rod 16 to move up and down via the pushing component 15, thereby causing several horizontal rods 17 on one side of the telescopic rod 16 and the through-type stirring rod 18 to move in the vertical direction. This structure, together with the horizontal rotation of the rotating stirring component 2, forms a three-dimensional stirring system. The rotating stirring component 2 disperses the masterbatch horizontally, while the vertical stirring component 3 covers different height areas within the mixing tank 1, effectively eliminating dead zones in the tank and ensuring that all matte masterbatch in the tank is fully stirred and dispersed, preventing clumping due to localized masterbatch remaining stationary for extended periods. Furthermore, the design of the stirring rod 18 penetrating the horizontal rods 17 enhances the structural stability of the stirring rod 18, ensuring that it can stably apply a dispersing force to the masterbatch during vertical movement, further optimizing the stirring effect.

[0033] In the example of this application, the pusher 15 is a push rod motor.

[0034] As a preferred example of this utility model, the pusher 15 is explicitly identified as a push rod motor. The push rod motor has the characteristics of stable output force and high motion precision, which can accurately control the extension stroke, extension speed and start / stop timing of the telescopic rod 16, thereby achieving precise control of the vertical movement amplitude and frequency of the stirring rod 18. It can flexibly adjust the vertical stirring parameters according to the different characteristics of the matting masterbatch, such as particle size, humidity and bulk density, to adapt to diverse masterbatch stirring needs and ensure that the anti-caking effect is achieved under the best stirring conditions. At the same time, the push rod motor has low noise and low vibration during operation, and has a long service life and low maintenance cost, which can ensure the long-term stable operation of the vertical stirring component 3 and improve the overall reliability and practicality of the device.

[0035] In the example of this application, the insulation layer 8 is a vacuum insulation structure.

[0036] As a preferred example of this utility model, the insulation layer 8 adopts a vacuum insulation structure. The vacuum environment can block heat conduction and heat convection to the greatest extent. Its heat insulation performance is far superior to that of conventional insulation materials. It can effectively reduce the heat loss of the heating medium in the heat jacket 4, keep the internal temperature of the heat jacket 4 in a stable range, and thus ensure that the matting masterbatch in the mixing tank 1 is always in a suitable temperature environment. In addition, the vacuum insulation structure does not require the filling of additional insulation materials, which can reduce the overall weight of the insulation layer 8, reduce the load on the device, and has a simple structure and long-lasting insulation performance. It does not require frequent replacement of insulation materials, thus reducing the later maintenance costs.

[0037] In the example of this application, the stirring tank 1 is made of a thermally conductive material.

[0038] As a preferred example of this utility model, the mixing tank 1 is made of a thermally conductive material, which enables the heat in the heat jacket 4 to be quickly and evenly transferred to the matte masterbatch inside the tank, avoiding heat accumulation or uneven transfer on the tank wall, ensuring that the overall temperature of the masterbatch inside the tank is consistent, and preventing moisture absorption and clumping due to local low temperature of the masterbatch; at the same time, the high thermal conductivity of the thermally conductive material can shorten the time for the masterbatch to reach the target temperature, improve heating efficiency, thereby shortening the overall mixing cycle and improving production efficiency.

[0039] The thermally conductive material is stainless steel, which is existing technology and will not be described in detail here.

[0040] In the example of this application, the mixing tank 1 has a feed inlet 9 at the top.

[0041] As a preferred example of this utility model, a feed inlet 9 is provided at the top of the mixing tank 1. On the one hand, the top feeding method conforms to the natural downward trend of materials, which facilitates the rapid and smooth entry of the matting masterbatch into the tank, effectively preventing masterbatch spillage during the feeding process and reducing material loss. On the other hand, the feed inlet 9 is located at the top, allowing the masterbatch to directly contact the rotating agitator 2 after entering the tank, and be quickly captured by the rotating agitator rod 13 and blades 14 and participate in the mixing, reducing the accumulation time of the masterbatch at the tank opening or the top of the tank, and avoiding initial agglomeration caused by accumulation. At the same time, the top feed inlet 9 is convenient for docking with automated feeding equipment to realize continuous and automated feeding of masterbatch, improving production continuity and efficiency.

[0042] In the example of this application, the outer wall of the mixing tank 1 is provided with a discharge port 10.

[0043] As a preferred example of this utility model, a discharge port 10 is provided on the outer wall of the mixing tank 1. This allows the matting masterbatch to be discharged directly from the tank wall after mixing, avoiding collisions between the masterbatch and the mixing components inside the tank during the discharge process, reducing wear on the mixing components and breakage of the masterbatch. At the same time, the discharge port 10 on the outer wall facilitates the installation of a discharge valve, which can precisely control the discharge speed and discharge volume to achieve orderly discharge and prevent the masterbatch from accumulating and clogging at the discharge port 10 due to excessively fast discharge. In addition, the setting of the discharge port 10 on the outer wall allows the masterbatch inside the tank to be emptied as much as possible, reducing the amount of masterbatch residue in the tank, preventing residual masterbatch from clumping together after long-term storage and affecting the quality of the next mixing operation, thus improving the practicality and cleanliness of the device.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
