Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettle equipment, in particular to an acrylic resin emulsification reaction kettle. Background Art

[0002] Compared with traditional solvent-based insulating paint, acrylic resin has the advantages of not containing solvents such as toluene, styrene, and solvent oil, and is a new type of environmentally friendly green product with zero VOC emissions. It eliminates the pollution caused by the use of solvent-based insulating paint to the factory environment, the living environment of residents around the factory, and the atmospheric environment. It greatly reduces the health hazards caused by the inhalation of toxic solvents by factory insulation processing operators (long-term inhalation of toluene, xylene, and styrene will kill a large number of human white blood cells, causing a decline in human immune function, and in severe cases will lead to the occurrence of diseases such as leukemia and lung cancer). At the same time, it also eliminates the safety hazards of customers in transportation, storage, and use.

[0003] The acrylic resin emulsification kettle is a reaction device for dissolving and emulsifying water-soluble insulating paint raw materials (tung oil, resin, propylene glycol methyl ether, etc.). For example, an acrylic resin emulsification kettle with a publication number of CN206613472U comprises a container and an upper cover, a filter plate is arranged near the bottom of the container, the filter plate divides the container into an upper cavity and a lower cavity, and a liquid outlet and a filtrate outlet are arranged in parallel at the bottom of the container.

[0004] The top cover of this emulsification kettle is provided with a number of air holes and water outlet pipes, so when adding materials to the inner cavity of the emulsification kettle, it is necessary to overcome the extra weight when removing the top cover. This brings a lot of trouble when adding materials to the emulsification kettle or replacing and cleaning the internal filter. At the same time, the water outlet pipe only absorbs heat at the bottom of the top cover, making the heat absorption area inside the reactor too small and thus the heat dissipation efficiency low. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-4As shown, the utility model is an acrylic resin emulsification reactor, comprising a reactor body 1, a working chamber is arranged inside the reactor body 1, and a reactor cover 2 is detachably arranged on the top of the reactor body 1. A support frame 3 is arranged at the bottom of the reactor body 1, a circle of water storage chamber 9 is arranged on the inner wall of the reactor body 1, a water inlet 7 and a water outlet 8 are arranged on one side of the reactor body 1, and the water inlet 7 is connected with the water outlet 8 and the water storage chamber 9. A stirring structure 4 is arranged on the bottom surface of the reactor cover 2, and a motor 41 of the stirring structure 4 is arranged on the top surface of the reactor cover 2, and the output end of the motor 41 passes through the reactor cover 2 and extends to the bottom of the reactor cover 2. A fixed sleeve 42 is fixedly arranged below the reactor cover 2, and the output end of the motor 41 passes through the fixed sleeve 42 and is coaxially fixedly connected with a rotating shaft 43. A circular cover 44 is fixedly provided at the bottom of the fixed sleeve 42, and an opening is provided at the bottom of the circular cover 44. The bottom of the rotating shaft 43 is passed through the inside of the circular cover 44, and a stirring blade 45 is fixedly provided at one end of the rotating shaft 43 located inside the circular cover 44. A shear arm 46 is coaxially fixedly connected to the bottom of the stirring blade 45, and the opening of the shear arm 46 is set upward. A turbulent gap 47 is provided between the shear arm 46 and the outer circular cover 44.

[0030] A filter plate 5 is provided inside the reactor body 1, and a diverter structure 6 is provided at the bottom of the reactor body 1. A vertical direct current port 61 of the diverter structure 6 is provided at the bottom of the reactor body 1, and the vertical direct current port 61 is connected to the reaction chamber of the reactor body 1. A coarse filter screen 63 and a fine filter screen 64 are provided inside the vertical direct current port 61, and the coarse filter screen 63 is located above the fine filter screen 64. An inclined discharge port 62 is provided on the side wall of the vertical direct current port 61, and the inclined discharge port 62 is connected to the vertical direct current port 61, and the inclined discharge port 62 is provided between the coarse filter screen 63 and the fine filter screen 64.

[0031] When using this acrylic resin emulsification reactor, the reactor cover 2 is removed from the top of the reactor body 1, and then the acrylic resin to be emulsified is placed inside the working chamber of the reactor body 1. Subsequently, the reactor cover 2 is fixedly installed between the reactor body 1, and the stirring structure 4 is started to stir the acrylic resin in the inner chamber of the reactor body 1. The output end of the motor 41 drives the rotating shaft 43 to rotate, and the bottom of the rotating shaft 43 drives the stirring blade 45 to rotate. When the stirring blade 45 rotates, it drives the shear arm 46 connected to the bottom to rotate. A turbulent gap 47 is set between the shear arm 46 and the circular cover 44. When the stirring blade 45 rotates, the internal negative pressure changes and attracts the acrylic resin to enter the interior through the turbulent gap 47. When the acrylic resin passes through the acrylic resin, it is subjected to relative rotation between the circular cover 44 and the shear arm 46, so that the acrylic resin is squeezed and ground, making it finer. After the stirring is completed, the stirring structure 4 stops working to allow the acrylic resin inside the working chamber to stand and emulsify. Acrylic resin with smaller particles can pass through the filter plate 5 to enter the bottom of the working chamber, and then enter the diversion structure 6. The acrylic resin enters the vertical direct current port 61, and is first filtered through the coarse filter 63. The acrylic resin passing through the coarse filter 63 contacts the fine filter 64 below. Thus, the emulsion is graded and screened to prevent the emulsion from being mixed with particles. The water storage chamber 9 is filled with water through the water inlet 7, and the water in the water storage chamber 9 is discharged through the water outlet 8. The water in the water storage chamber 9 can absorb the working heat inside the reactor body 1. Prevent the surface temperature of the reactor body 1 from overheating.

[0032] The water inlet 7 and the water outlet 8 are located on the same vertical line, making it more convenient to replace the condensed water in the water storage chamber 9; the fixed sleeve 42 is located on the central axis of the bottom of the kettle cover 2, so that the stirring structure 4 can stir evenly in the working chamber.

[0033] Working principle of the utility model: an acrylic resin emulsification reactor of the utility model is provided with a reactor cover 2, which is detachable from a reactor body 1, and only stirring structures 4 are provided on both sides of the reactor cover 2, so that the weight of the reactor cover 2 itself is reduced, so that it is convenient to disassemble it at the top of the reactor body 1, so as to facilitate the subsequent feeding of materials into the working chamber of the reactor body 1; a water storage chamber 9 is provided in the side wall of the reactor body 1, so that the heat absorption surface is increased and the weight of the reactor cover 2 is reduced, so as to facilitate its disassembly; a stirring structure 4 is provided, and the stirring blades 45 of the stirring structure 4 drive the acrylic resin to be evenly stirred, and at the same time, relative rotation occurs between the shear arm 46 and the circular cover 44, so that the relative rotation grinds the acrylic resin, refines the particles inside the acrylic resin, and facilitates the subsequent static emulsification and stratification.

[0034] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model.
