Abstract
Description
Technical Field
[0001] This utility model relates to the field of urea-formaldehyde resin adhesive processing technology, specifically a dilution device for urea-formaldehyde resin adhesive processing. Background Technology
[0002] In the processing of urea-formaldehyde resin adhesives, dilution is necessary to reduce the viscosity. After the urea-formaldehyde resin adhesive is prepared, it is diluted as needed. This dilution stage primarily aims to adjust the adhesive's viscosity, flowability, and open time to meet the requirements of subsequent construction.
[0003] Existing urea-formaldehyde resin adhesives require the addition of acetone for dilution during the dilution process, and the two are mixed evenly using a stirring device. However, due to the strong viscosity of urea-formaldehyde resin adhesives, the mixing time is long. Furthermore, simply increasing the stirring speed not only results in uneven mixing but also causes raw materials to splash, posing a safety hazard.
[0004] The reason for this problem is that adhesives have strong viscosity, resulting in longer mixing times. This is because viscous substances are more likely to form clumps or agglomerates, making mixing and dispersion more difficult. Simply increasing the mixing speed makes the viscous material more likely to adhere to the walls of the mixer or container, forming residues that are difficult to remove. This not only leads to uneven mixing but also wastes raw materials. During high-speed mixing, the viscous material can splash out due to strong shear forces. This can pollute the working environment and cause injury to operators, presenting limitations. Therefore, we propose a dilution device for urea-formaldehyde resin adhesive processing to solve the above problems. Utility Model Content

[0026] This application provides a dilution device for processing urea-formaldehyde resin adhesive, which solves the problem that the strong viscosity of urea-formaldehyde resin adhesive leads to a long mixing time, and that simply increasing the stirring speed not only results in uneven mixing but also causes raw material splashing, posing a safety hazard.
[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0028] Example 1
[0029] This utility model discloses a dilution device for processing urea-formaldehyde resin adhesives. According to the appendix... Figure 1-2 As shown, it includes a mixing tank 1, and the mixing tank 1 is equipped with a dual-shaft mixing unit 2 for mixing raw materials. The dual-shaft mixing unit 2 includes a layered baffle 21, a mixing component 22 and a flow component 23.
[0030] A layered baffle 21 is installed in the middle of the mixing tank 1, dividing the interior of the mixing tank 1 into an upper mixing zone and a lower mixing zone. Agitators 22 are installed inside the upper and lower mixing zones respectively, with the upper mixing zone having a slower mixing speed and the lower mixing zone having a faster mixing speed. A flow-through component 23 is installed inside the layered baffle 21, which guides the flow direction of the raw material between the upper and lower layers to complete the internal circulation of the raw material.
[0031] The mixing component 22 includes a first motor 221 and a first rotating shaft 222; the first motor 221 is positioned above the mixing tank 1; the first rotating shaft 222 is positioned below the mixing tank 1, and the output shaft of the first motor 221 is fixedly assembled with the first rotating shaft 222. The mixing component 22 also includes a second motor 224 and a second rotating shaft 225; the second motor 224 is fixedly assembled at the bottom of the mixing tank 1; the second rotating shaft 225 is positioned above the second motor 224, and the output shaft of the second motor 224 is fixedly assembled with the second rotating shaft 225. The second rotating shaft 225 is rotatably connected to the layered baffle 21. The mixing component 22 also includes a frame-type agitator 223 and a propeller-type agitator 224. A stirrer 226; a frame stirrer 223 is located below the first rotating shaft 222 and is rotatably connected to the layered baffle 21; a propeller stirrer 226 is located inside the mixing tank 1 and is fixedly assembled with the second rotating shaft 225; the flow member 23 includes a discharge port 231, a feed column 232, and a guide channel 233; the discharge port 231 is located on both sides of the layered baffle 21; the feed column 232 is located at both ends of the layered baffle 21; the guide channel 233 is located inside the feed column 232; a support frame 24 is fixedly installed on the top of the mixing tank 1, and the first motor 221 is fixedly assembled on the top of the support frame 24.
[0032] In this embodiment, when using the device, the raw material is poured into the mixing tank 1. The raw material falls into the lower mixing zone through the discharge port 231 and the guide channel 233. After the injection is completed, there is a gap between the raw material in the lower mixing zone and the layering baffle 21. At this time, acetone is added into the mixing tank 1. At the same time, the first motor 221 and the second motor 224 are started. The first motor 221 and the second motor 224 drive the first rotating shaft 222 and the second rotating shaft 225 to rotate, which in turn drives the frame agitator 223 and the propeller agitator 226 to rotate. The second motor... The faster rotation speed of motor 224 allows propeller-type mixer 226 to quickly mix the raw materials, while the slower rotation speed of motor 221 allows frame mixer 223 to mix the raw materials at a uniform speed, preventing splashing. Due to the faster speed of the lower mixing zone, the raw materials inside the lower mixing zone are guided into the upper mixing zone through guide channel 233. Under the action of gravity, the material in the upper mixing zone falls into the lower mixing zone through discharge port 231, completing the internal circulation of the raw materials, improving mixing efficiency and meeting user needs.
