Description

Technical Field

[0001] This utility model relates to the technical field of stirring devices, specifically to an epoxy resin self-leveling stirring device that prevents metal particles from being mixed in. Background Technology

[0002] Epoxy self-leveling flooring is a high-performance flooring material made of epoxy resin as the base material, mixed with curing agents, fillers and additives. Due to its self-leveling, high strength, wear resistance and corrosion resistance, it is widely used in industrial plants, electronic workshops, commercial places and other fields.

[0003] Epoxy resin self-leveling mixing devices are equipment used to produce epoxy resin self-leveling compounds. For example, Chinese patent application No. 202120109769.2 discloses a high-efficiency mixing device for polymer self-leveling compounds, which describes the specific structure and working principle of a mixing device that can mix epoxy resin self-leveling compounds. The core components of existing epoxy resin self-leveling mixing devices, such as mixing blades, shafts, and mixing tanks, are usually made of carbon steel. When mixing high-hardness fillers for a long time, iron filings are easily generated due to wear. In addition, auxiliary components such as bearings, valves, and pipe connections may also detach metal fragments or rust into the mixing material due to aging, corrosion, or loosening. These metal particles mixed into the self-leveling material may cause incomplete curing of the final product, reducing the overall strength of the finished product. After the epoxy resin self-leveling compound is actually applied to the ground, the metal particles mixed in will damage its corrosion resistance. Moreover, the high density of metal particles makes them easy to settle, which will affect the leveling properties of the finished product after it is applied to the ground, causing color differences, spots, or unevenness on the surface of the cured product.

[0017] Figure 2 This is a schematic diagram of the electromagnetic adsorption component structure of the epoxy resin self-leveling stirring device for preventing the mixing of metal particles provided in Embodiment 1 of this utility model. Detailed Implementation

[0018] Example 1:

[0019] The epoxy resin self-leveling stirring device for preventing the mixing of metal particles provided in Embodiment 1 of this utility model, such as Figures 1 to 2 As shown, it includes a stirring device body 1 and an electromagnet adsorption component 2; the stirring device body 1 includes a discharge port 11; the electromagnet adsorption component 2 is disposed at the discharge port 11; the electromagnet adsorption component 2 can generate a magnetic field to adsorb metal particles flowing out of the discharge port 11 when energized.

[0020] The epoxy resin self-leveling mixing device for preventing metal particle contamination provided in Embodiment 1 of this utility model is used in which the material is normally mixed in the mixing device body 1. The mixing device body 1 is prior art, and its specific structure and working principle will not be described in detail here. It has a discharge port with a valve. In this embodiment, the electromagnet adsorption component 2 is set after the valve (after the valve means that the epoxy resin self-leveling after mixing passes through the valve first and then through the electromagnet adsorption component 2). The electromagnet adsorption component 2 is not energized when the mixing device body 1 is mixing normally, and the electromagnet adsorption component 2 does not generate magnetism. When the epoxy resin self-leveling is to be output after mixing, the electromagnet adsorption component 2 is energized and becomes magnetic, adsorbing the metal particles in the epoxy resin self-leveling, thereby reducing the metal particle content of the epoxy resin self-leveling product. Compared with the prior art, this embodiment can adsorb the metal particles in the epoxy resin self-leveling, thereby reducing the spots and unevenness on the ground (after epoxy resin self-leveling) caused by metal particles.

[0021] The epoxy resin self-leveling stirring device for preventing the mixing of metal particles provided in Embodiment 1 of this utility model solves the problem of high metal particle content and poor quality of epoxy resin self-leveling after production in the prior art, and can reduce the metal particles mixed in the finished epoxy resin self-leveling material.

[0022] Since electromagnets are typically made by winding wires around metal, and the metal becomes magnetic when the wires are energized, directly placing the electromagnet at the outlet 11 poses a risk of leakage, and the heat from the wires may solidify the self-leveling compound. To address this issue, in this embodiment, the electromagnet adsorption assembly 2 includes an electromagnet 21 and a silicon steel adsorption block 22. The silicon steel adsorption block 22 is disposed on the inner wall of the outlet 11. The electromagnet 21 can form a closed magnetic circuit with the silicon steel adsorption block 22. In this embodiment, when the electromagnet 21 is energized, it magnetizes the soft magnetic material silicon steel adsorption block 22, making the silicon steel adsorption block 22 a temporary magnet. The silicon steel adsorption block 22 is disposed inside the outlet 11, thereby avoiding direct contact between the electromagnet 21 and the self-leveling material.

[0023] As a preferred embodiment, the silicon steel adsorption block 22 has a mesh structure. Through the perforated mesh structure, the silicon steel adsorption block 22 forms a three-dimensional adsorption surface, which significantly increases the contact area with the epoxy resin fluid compared to a solid structure, thereby better adsorbing metal particles within the epoxy resin fluid.

[0024] As a preferred embodiment, in this case, a groove 111 is provided on the inner wall of the discharge port 11; an elastic block 221 is provided on the edge of the silicon steel adsorption block 22; the elastic block 221 matches the groove 111; the elastic block 221 is detachably fixed in the groove 111; the silicon steel adsorption block 22 is fixed in the discharge port 11 by the cooperation of the elastic block 221 and the groove 111. When the silicon steel adsorption block 22 is saturated with adsorbed metal particles, it can be disassembled separately for cleaning or replacement, avoiding the need to disassemble the entire stirring device as required by the fixed structure, thus reducing downtime; the elastic block 221 utilizes the deformation capacity of the material and can be directly pressed into the groove 111 or pried out by hand, facilitating assembly.

[0025] As a preferred embodiment, this model further includes a guide cone 3; the guide cone 3 is conical; the guide cone 3 is fixed inside the outlet 11 by a connecting rod 4; the silicon steel adsorption block 22 is disposed outside the guide cone 3; the tip of the guide cone 3 faces away from the silicon steel adsorption block 22. The self-leveling fluid first contacts the tip of the guide cone 3, then passes through the silicon steel adsorption block 22, and then flows out; the guide cone 3 can prevent the fluid from directly impacting the silicon steel adsorption block, which could cause particle escape; the 60° cone angle makes the fluid radially and uniformly distributed along the cone surface of the guide cone 3, ensuring the uniformity of the flow velocity at the outlet cross-section and ensuring that the silicon steel adsorption block 22 can adsorb in the entire circumference.

[0026] As a preferred embodiment, in this case, a Teflon coating is provided inside the discharge port 11; a Teflon coating is also provided on the surface of the guide cone 3. The Teflon coating has a low coefficient of friction, which helps to reduce the resistance of the epoxy resin fluid along the flow path.

[0027] As a preferred embodiment, in this case, the cone angle of the guide cone 3 is 60°; the maximum cross-sectional area of ​​the guide cone 3 accounts for 60% of the outlet 11. The combination of the 60° cone angle and the 60% cross-sectional area keeps the fluid Reynolds number Re between 2300 and 2800 (laminar critical Re=2300), which is within the optimal control range of the transition flow. This ensures the orderliness of the fluid and enhances the suspension capacity of the metal particles through moderate turbulence, facilitating the contact between the metal particles and the silicon steel adsorption block 22.

[0028] As a preferred embodiment, in this case, the electromagnet 21 is disposed on the outer wall of the pipe at the outlet 11. The electromagnet 21, disposed on the outer wall of the pipe at the outlet 11, magnetizes the silicon steel adsorption block 22 disposed inside the pipe at the outlet 11, thereby avoiding direct contact between the electromagnet 21 and the epoxy resin self-leveling fluid, avoiding malfunctions caused by exposed wires, and avoiding curing of the epoxy resin self-leveling due to heating of the wires.

[0029] In summary, this utility model provides an epoxy resin self-leveling mixing device to prevent the ingress of metal particles, relating to the technical field of mixing devices. It includes a mixing device body and an electromagnet adsorption component. The mixing device body includes a discharge port; the electromagnet adsorption component is disposed at the discharge port; the electromagnet adsorption component can generate a magnetic field to adsorb metal particles flowing out of the discharge port when energized.
