Description

Technical Field

[0001] The utility model relates to the technical field of water - resistant acrylate emulsion production, and specifically relates to a reaction device for water - resistant acrylate emulsion. Background Art

[0002] Acrylate emulsion polymers are widely used in coating printing, electrostatic flocking, fabric laminating, warp sizing and coating processing, etc. Various acrylate types with different properties also have their own different uses due to the differences in raw materials and ratios used. The water - resistant acrylate emulsion has a uniform emulsion particle size distribution, high emulsion stability, good comprehensive film properties, good waterproof performance, and the waterproof performance can reach a relatively high level.

[0003] For example, in Chinese Patent CN212790983U, the utility model relates to a reaction device for acrylate emulsion, including a bracket. A reaction tank is fixedly connected to the bracket. A feed pipe for adding materials is fixedly connected to the upper surface of the reaction tank. A discharge pipe is fixedly connected to the lower surface of the reaction tank. A control valve is fixedly connected to the discharge pipe. A mounting rod is rotatably connected to the upper surface of the reaction tank. A U - shaped rod is fixedly connected to the end of the mounting rod extending into the reaction tank. A stirring mechanism is provided at one end of the U - shaped rod. A number of groups of stirring blades are fixedly connected to the outer wall of the U - shaped rod. A driving mechanism for driving the mounting rod to rotate is provided on the upper surface of the outer wall of the reaction tank. By driving the mounting rod to rotate through the driving mechanism, the mounting rod drives the U - shaped rod to move.

[0037] In this embodiment, installation grooves are provided between opposite sides of the fixed box 303 and the fixed block 306 , bearings are fixed inside the installation grooves, the length of the closing plate 305 is greater than the diameter of the feed pipe 2 , and a sealing gasket is fixed on the lower surface of the closing plate 305 .

[0039] The working principle of the above embodiment is:

[0040] (1) Turn on the faucet, and water enters the water supply tank 103 through the water supply pipe 107. When the water level in the water supply tank 103 is higher than the second hydraulic pressure sensor 105, the solenoid valve 106 starts to close the water supply pipe 107. At the same time, the temperature sensor 104 detects the water temperature. When the water temperature is lower than 84 degrees, the heating pipe 101 is started. The heating pipe 101 heats the water to 84 degrees and then closes. When the reaction device body 4 starts to process and produce water-resistant acrylic emulsion and hot water is needed, the water pump 109 is started. The water pump 109 draws water from the water supply tank 103 through the water suction pipe 110 and passes through the water delivery pipe 10 8 is transported to the interior of the reaction device body 4. When the temperature sensor 104 detects that the water temperature inside the water supply tank 103 is less than eighty-four degrees, the water pump 109 cannot be started and can only be started after the water temperature reaches eighty-four degrees. The insulation mechanism 1 detects the water temperature inside the water supply tank 103 in real time through the temperature sensor 104, and cooperates with the heating pipe 101 to ensure that the water temperature can be heated and raised back to eighty-four degrees at any time after it is lowered. The first hydraulic sensor 102 and the second hydraulic sensor 105 cooperate to detect the water output inside the water supply tank 103 in real time to avoid insufficient remaining water to be added to the reaction device body 4.

[0041] (2) When it is necessary to replenish materials into the interior of the reaction device body 4 through the feed pipe 2, the drive motor 302 is started. The drive motor 302 drives the rotating shaft 301 to rotate through the output shaft, and drives the rotating seat 304 to rotate through the rotating shaft 301. The closing plate 305 rotates together with the rotating seat 304 and moves away from the feed pipe 2. When the rotating seat 304 rotates ninety degrees, the drive motor 302 is closed. At this time, the mouth of the feed pipe 2 is open and materials can be put in. After the putting is completed, the drive motor 302 is started again to rotate it in the opposite direction, driving the closing plate 305 to move closer to the feed pipe 2 until the feed pipe 2 is closed. The closing mechanism 3 automatically rotates the closing plate 305 through the cooperation of the rotating shaft 301, the drive motor 302, the fixed box 303, the rotating seat 304 and the fixed block 306, so as to facilitate the staff to open or close the feed pipe 2, thereby avoiding the problem that the internal heat of the reaction device body 4 is lost through the feed pipe 2 when processing materials to produce water-resistant acrylic emulsion, resulting in a decrease in production efficiency.
