Technical Field

[0001] This utility model relates to the field of coating emulsification technology, specifically to a building coating emulsification reaction device. Background Technology

[0002] Emulsification refers to the process of uniformly dispersing one liquid into extremely small droplets in another immiscible liquid. In chemical production, mechanical force is usually required for auxiliary stirring and emulsification. Reactors are commonly used as emulsification reaction equipment for sealed and efficient emulsification reaction of architectural coatings. Taking the emulsification reaction equipment of architectural coatings as an example.

[0003] Some architectural coating emulsification reaction equipment uses a fixed, integrated stirring structure, which is inconvenient for regular disassembly and replacement. Furthermore, the stirring structure is not very effective in mixing, homogenizing, and preventing foaming during the coating emulsification reaction. Therefore, this paper proposes an architectural coating emulsification reaction equipment to address these issues. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An emulsification reaction device for architectural coatings includes a stirring mechanism, an upper reaction vessel cover, and a lower reaction vessel cylinder. The stirring mechanism includes a variable frequency motor, a shaft, connecting pipes, an annular cylinder, a combined cover, a threaded cylinder, a silicone ring, a scraper, an upper connecting frame, a lower connecting frame, a stirring plate frame, and a connecting rod. A shaft is installed at the bottom of the variable frequency motor. Two connecting pipes are symmetrically and fixedly arranged at the left and right ends of the shaft. An annular cylinder is fixedly installed at the top of the connecting pipe. A threaded cylinder is fixedly installed at the bottom of the combined cover. The threaded cylinder and the annular cylinder are internally threaded together. A silicone ring is installed between the inner sides of the annular cylinder and the combined cover.

The shaft 102 is installed at the bottom of the variable frequency motor 101, and the left and right ends of the shaft 102 are symmetrically distributed and fixed. Two connecting pipes 103 are provided. A ring cylinder 104 is fixedly installed at the top of the connecting pipe 103. A threaded cylinder 106 is fixedly installed at the bottom of the combined cover 105. The threaded cylinder 106 is threadedly assembled with the ring cylinder 104. A silicone ring 107 is installed between the inner sides of the ring cylinder 104 and the combined cover 105. An upper connecting frame 109 and a lower connecting frame 110 are fixedly installed at one end of the scraper plate 108 near the shaft 102. A connecting rod 112 is fixedly installed at the top of the stirring plate frame 111, forming a combined installation stirring mechanism 1.

[0027] A silicone ring is fitted on the outer side of the connecting rod 112. The connecting rod 112 and the shaft 102 are slidably inserted into each other. This arrangement forms an integrated installation of the stirring plate frame 111 and the connecting rod 112. The lower connecting frame 110 is slidably inserted into the silicone ring in the inner groove of the stirring plate frame 111. The upper connecting frame 109 is slidably inserted into the silicone ring inside the connecting pipe 103, the inside of the shaft 102, and the inside of the connecting rod 112. This arrangement forms a sealed installation structure. The inside of the connecting pipe 103, the inside of the silicone ring inside the connecting pipe 103, and the inside of the upper connecting frame 109 are threaded together using locking studs. This arrangement forms the combined installation structure of the stirring mechanism 1. The variable frequency motor 101 is installed on the top of the upper reaction vessel cover 2. The lower reactor cylinder 3 is installed at the bottom of the upper reactor cover 2 via a sealing ring and studs. A jacket plate 4 is fixedly installed on the outside of the lower reactor cylinder 3. A cooling sleeve 5 is installed inside the jacket plate 4. A heat transfer oil inlet pipe 6 is fixedly installed on the lower left side of the jacket plate 4. A heat transfer oil outlet pipe 7 is fixedly installed on the upper right side of the jacket plate 4. An electromagnetic discharge valve 8 is installed at the bottom of the lower reactor cylinder 3.

The pilot-operated safety valve 11 is used to maintain a reasonable pressure environment inside the sealed reactor. The diaphragm metering pump 9 is connected to the building pre-emulsified coating delivery pipeline and performs the function of drip metering and feeding through the diaphragm metering pump 9.

[0028] Work Process: This utility model provides an emulsification reaction device for architectural coatings. The main body of the device adopts an assembled emulsification composite stirring structure, which can be disassembled and replaced periodically. The stirring structure provides good stirring and homogenization effects for the coating emulsification reaction. The electrical equipment involved is controlled by a PLC controller. The heat transfer oil inlet pipe 6 is connected to the inlet of the existing reactor heating oil conveying pipeline system, and the heat transfer oil outlet pipe 7 is connected to the outlet of the existing reactor heating oil conveying pipeline system. This ensures continuous flow of heating oil between the lower reactor cylinder 3 and the jacket plate 4. The pre-emulsified building coating, which is dripped into the lower reactor vessel 3, is heated. The top left port and bottom right port of the cooling sleeve 5 are connected to the existing reactor cooling pipeline system to regulate the temperature of the heating oil. This, combined with the temperature sensor 10, regulates the temperature of the building coating emulsion. The pilot-operated safety valve 11 maintains a reasonable pressure environment inside the sealed reactor. The diaphragm metering pump 9 is connected to the pre-emulsified building coating delivery pipeline, and drip-feeds the coating. Before the equipment is put into use, the stirring mechanism 1 is pre-assembled onto the reactor cover 2. (The connecting rod...) A silicone ring is fitted on the outer side of 112. The connecting rod 112 and the shaft 102 are slidably inserted into each other until the silicone ring on the outer side of the connecting rod 112 is in a state of contact and compression. The lower connecting frame 110 and the silicone ring in the inner groove of the mixing plate frame 111 are slidably inserted into each other. The upper connecting frame 109 and the silicone ring inside the connecting pipe 103, the shaft 102, and the connecting rod 112 are slidably inserted into each other. The inside of the connecting pipe 103, the inside of the silicone ring inside the connecting pipe 103, and the inside of the upper connecting frame 109 are threaded together using locking studs. The threaded cylinder 106 and the ring cylinder 104 are threaded together. 04. A silicone ring 107 is installed between the inner sides of the combined cover 105 to seal and protect the locking studs. The variable frequency motor 101 is started to drive the stirring plate 111 and the scraper 108 to rotate. The rotational resistance generated after the stirring plate 111 rotates is small, which reduces the intensity of stirring. Together with the scraper 108, it can perform peripheral annular stirring of the building coating emulsion. The combined stirring structure is set up with the variable frequency motor 101 to provide high shear force to disperse the monomers into fine droplets while reducing the intensity of stirring of the building coating emulsion inside the lower reaction vessel 3, so that foam is not easily generated during the emulsification stirring process.

[0029] Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined by the appended claims and their equivalents.
