Description

Technical Field

[0001] This utility model relates to the technical field of epoxy resin processing equipment, specifically to an epoxy resin mixture separation and filtration device in epoxy resin production. Background Technology

[0002] Epoxy resin, as a high-performance polymer material, is widely used in coatings, adhesives, composite materials, and many other fields. Its product quality directly depends on the separation and filtration efficiency of the mixture during the production process. In the epoxy resin production process, the resulting mixture often contains solid impurities of different particle sizes, incompletely reacted raw material particles, and byproducts. If these components cannot be efficiently separated, it will seriously affect the stability of the subsequent curing process and reduce the mechanical properties, corrosion resistance, and other key indicators of the final product.

[0003] Currently, most epoxy resin mixture separation and filtration equipment used in the industry employs a single sieve structure or a multi-stage series sieve structure. A single sieve structure can only achieve single-pass filtration and cannot separate components of different particle sizes, requiring multiple repeated filtration operations, which is not only inefficient but also increases production energy consumption. While a multi-stage series sieve structure can achieve graded separation, it usually requires multiple independent drive units to drive each stage of the sieve components, resulting in a large overall equipment size, complex structure, and high manufacturing and maintenance costs.

[0004] Meanwhile, existing multi-stage screening equipment often uses fixed screening components or simple vibration methods, which easily leads to material accumulation and screen blockage during screening, resulting in a gradual decrease in screening efficiency. Furthermore, material transfer between different screening levels requires additional conveying equipment, increasing the complexity of the equipment layout and potentially causing material residue and waste. In addition, some equipment has an unreasonable drive transmission structure design, resulting in low power transmission efficiency and problems such as jamming and excessive noise during operation, affecting the continuous and stable operation of the equipment and making it difficult to meet the needs of large-scale industrial production. Utility Model Content

[0005] Technical problems to be solved In view of the above-mentioned shortcomings of the prior art, the present invention provides an epoxy resin mixture separation and filtration device in epoxy resin production, which can effectively solve the problems in the prior art.

[0006] Technical solution

[0007] This utility model provides an epoxy resin mixture separation and filtration device for epoxy resin production, including a base platform. A driving device is provided on one side of the base platform. The driving device includes a motor fixed to the outside of the base platform, a driving rod connected to the motor, and multiple sets of arc-shaped rods fixed on the driving rod. A screening assembly is fixed to the top of the base platform. The screening assembly includes a top screen, a bottom screen, and a receiving chamber. The top screen and the bottom screen are stacked and connected together. The three sets of arc-shaped rods are respectively placed inside the structure of the top screen, the bottom screen, and the receiving chamber.

[0008] Furthermore, each of the top screen, bottom screen, and receiving bin has a discharge port on one side, and the bottom of each set of discharge ports is connected to the pipeline. The discharge port in the middle is symmetrically arranged on the other side of the upper and lower sets of discharge ports.

[0009] Furthermore, both the top screen and the bottom screen have a central trough in the middle.

[0010] Furthermore, the bottom end of the drive rod is connected to the power output end of the motor via a belt.

[0011] Furthermore, the cross-section of each set of arc-shaped rods has a vortex structure.

[0012] Furthermore, the top screen and bottom screen are arranged in a top-to-bottom order with gradually increasing mesh size, and the middle part of the drive rod is rotatably sleeved in the base platform through the mounting bracket.

[0013] Beneficial effects

[0014] In this invention, the device employs a grading system with top and bottom screens of gradually increasing mesh size from top to bottom. Combined with three sets of arc-shaped rods placed inside the top screen, bottom screen, and receiving chamber, it achieves precise grading and separation of components with different particle sizes in epoxy resin mixtures. The vortex-shaped arc-shaped rods, when rotated by the drive rod, provide a directional pushing effect on the material, preventing material accumulation and clogging on the screen surface while accelerating the material's passage through the screen. Compared to traditional vibrating screening methods, the purity of the separated components at each stage is significantly improved.

[0015] In this device, discharge ports are located on one side of the top screen, bottom screen, and receiving bin, while the central discharge port is symmetrically positioned on the other side of the upper and lower sets of discharge ports. Each set of discharge ports is connected to a pipeline. This layout design allows materials separated at each stage to be directly and directionally discharged through the corresponding pipelines, eliminating the need for additional material transfer equipment. This achieves continuous operation from screening and separation to material collection, reducing material residue and waste. Simultaneously, the central trough provides ample space for the rotation of the arc-shaped rod, ensuring smooth material flow during the screening process and further guaranteeing production continuity.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example: An epoxy resin mixture separation and filtration device in epoxy resin production, as shown in the attached document. Figure 1 -Appendix Figure 3The device includes a base platform 1, a drive device 2 on one side of the base platform 1, a motor 21 fixed to the outside of the base platform 1, a drive rod 23 connected to the motor 21, and multiple sets of arc rods 22 fixed to the drive rod 23. A screening assembly 3 is fixed to the top of the base platform 1. The screening assembly 3 includes a top screen 31, a bottom screen 32, and a receiving chamber 33. The top screen 31 and the bottom screen 32 are stacked and connected. The three sets of arc rods 22 are respectively placed inside the structure of the top screen 31, the bottom screen 32, and the receiving chamber 33. The device adopts a grading setting with the top screen 31 and the bottom screen 32 gradually increasing in mesh size from top to bottom. With the three sets of arc rods 22 placed inside the top screen 31, the bottom screen 32, and the receiving chamber 33, the device can achieve precise grading and separation of different particle size components in epoxy resin mixtures. When the vortex-shaped arc rod 22 rotates under the drive rod 23, it can directionally push the material, which not only avoids the accumulation and blockage of the material on the screen surface, but also accelerates the rate at which the material passes through the screen. Compared with the traditional vibrating screening method, the purity of the separated components at each stage is significantly improved.

[0022] The top screen 31, the bottom screen 32 and the receiving bin 33 are each provided with a discharge port 321 on one side, and the bottom end of each set of discharge ports 321 is connected to the pipeline. The discharge port 321 in the middle is symmetrically arranged on the other side of the upper and lower sets of discharge ports 321.

[0023] Both the top screen 31 and the bottom screen 32 have a central groove 34. A single motor 21, in conjunction with a drive rod 23, synchronously drives the three sets of arc-shaped rods 22, eliminating the need for independent drive devices 2 for each stage of the screening components 3. This simplifies the equipment structure and reduces its footprint. Simultaneously, the bottom end of the drive rod 23 is connected to the power output end of the motor 21 via a belt, and the middle part is rotatably mounted within the base platform 1 via a mounting bracket 24. This transmission structure design ensures the stability and efficiency of power transmission, reducing power loss. Compared to traditional multi-stage independent drive devices 2, the equipment manufacturing and maintenance costs are also correspondingly reduced. The top screen 31, bottom screen 32, and receiving bin 33 each have a discharge port 321 on one side, with the central discharge port 321 symmetrically positioned on the other side of the upper and lower sets of discharge ports 321. Each set of discharge ports 321 is connected to a pipeline. This layout design allows the separated materials to be directly and directionally discharged through the corresponding pipelines, eliminating the need for additional material transfer equipment. This achieves continuous operation from screening and separation to material collection, reducing material residue and waste. Meanwhile, the configuration of the middle trough 34 provides ample space for the rotation of the arc-shaped rod 22, ensuring smooth flow of materials during the screening process and further guaranteeing the continuity of production.

[0024] The bottom end of the drive rod 23 is connected to the power output end of the motor 21 via a belt; the cross-section of each set of arc-shaped rods 22 is a vortex structure; the top screen 31 and bottom screen 32 gradually increase in mesh size from top to bottom, and the middle part of the drive rod 23 is rotatably mounted in the base 1 via the mounting bracket 24; the overall structure of the device is stably supported by the base 1, and the design of the rotational cooperation between the drive rod 23 and the mounting bracket 24 effectively reduces vibration and noise during equipment operation, improving the stability and service life of the equipment. In addition, the top screen 31 and bottom screen 32 are stacked and docked, which facilitates disassembly and cleaning, and allows for flexible replacement of the screen mesh size according to the needs of different production processes. It is suitable for the separation and filtration needs of epoxy resin mixtures of different specifications, enhancing the versatility and adaptability of the equipment.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
