Description

Technical Field

[0001] The present invention relates to a sulfonated enamel reactor for preparing adhesives, belonging to the technical field of reactors. Background Art

[0002] An enamel reactor is a composite material product in which glass containing high silica is lined on the inner surface of a steel container and firmly adhered to the metal surface through high-temperature burning. Therefore, it has the dual advantages of the stability of glass and the strength of metal, and is an excellent corrosion-resistant device. In the production of chemical products, a chemical reaction is carried out in the reactor. Many raw materials are solid at room temperature and need to be melted for mixing during use. The mixing process is generally achieved through a stirrer.

[0003] For example, a Chinese invention patent with the publication number CN106732251A discloses a sulfonated enamel reactor for preparing adhesives, including an enamel reactor tank body and an upper cover. A metal sealing ring is arranged at the upper port of the enamel reactor tank body. The wall surface of the enamel reactor tank body is sequentially provided with a stainless steel rust-proof layer, an outer layer of the tank body, and an inner layer of the tank body from outside to inside. A fluid cavity is arranged between the inner surface of the outer layer of the tank body and the outer surface of the inner layer of the tank body. A fluid inlet is arranged at the upper end of the enamel reactor tank body, and a fluid outlet is arranged at the lower end of the enamel reactor tank. A raw material dispersion device is detachably arranged on the inner surface of the inner layer of the tank body. The raw material dispersion device includes a connecting plate, and a raw material dispersion rack, a first raw material dispersion tooth, a raw material crushing knife, and a second raw material dispersion tooth are sequentially welded on the inner surface of the connecting plate from bottom to top.

[0004] The above-mentioned solution has the following deficiencies in actual use: This solution uses the fluid cavity inside the wall surface of the enamel reactor tank body to add cooling water or heat-conducting oil, and the raw materials in the enamel reactor tank will be quickly dispersed when they encounter the raw material dispersion rack, the first raw material dispersion tooth, the raw material crushing knife, and the second raw material dispersion tooth during the stirring and rotating process. However, in actual use, only a single fluid cavity is used for temperature adjustment, and it is impossible to accurately control the temperatures of different regions inside the reactor, making it difficult to meet the reaction requirements sensitive to temperature during the preparation of adhesives. Moreover, the raw materials in the tank are dispersed when they come into contact with the raw material dispersion rack, the raw material dispersion teeth, and the crushing knife during the stirring and rotating process, but this dispersion method is not efficient and uniform enough, and the mixing uniformity of the adhesive raw materials directly affects the performance of the product.

[0021] Please refer to Figures 1-9 , the present invention provides a technical solution: As Figure 1 shown, a sulfonated enamel reactor for preparing adhesives includes a carrier frame 100. The carrier frame 100 serves as the support foundation for the entire device and provides a stable installation platform for other components.

[0026] As Figure 5 shown, the stirring unit 300 includes a motor 301. The motor 301 is connected to the reaction kettle body 200 through a frame, providing a power source for stirring.

[0028] Furthermore, a plurality of connecting arms 304 are provided on the lower surface of the lowermost mounting ring 1 303. Lower scraping blades 305 are provided at the bottom ends of the connecting arms 304. The lower scraping blades 305 are in contact with the bottom of the inner wall of the inner kettle body 204, and can scrape the materials at the bottom of the inner kettle body in time to prevent material accumulation. In addition, the ends of the stirring columns 306 on the lowermost mounting ring 1 303 are all sleeved with connecting rods 310 through mounting grooves 309. One end of the connecting rod 310 is provided with an elastic member 311, and the other end of the connecting rod 310 is provided with a side scraping blade 312 for cleaning the inner side wall of the inner kettle body 204, which can effectively clean the materials attached to the inner side wall of the inner kettle body.

[0029] As Figure 7 shown, the second stirring member includes a plurality of mounting rings 2 313. A plurality of first stirring blades 314 are provided on the outer peripheral side of the mounting rings 2 313. The first stirring blades 314 are inclined, and the inclination angle is 40-50°. A guide cylinder 315 is provided at the ends of the plurality of first stirring blades 314. A plurality of second stirring blades 316 are provided on the outer peripheral side of the guide cylinder 315. The inclination direction of the second stirring blades 316 is opposite to that of the first stirring blades 314. A plurality of through holes 317 are provided in the guide cylinder 315. This structural design can make the materials form a complex flow path during the stirring process, further improving the stirring and mixing effect.

[0030] As Figure 8 and Figure 9 shown, the independent temperature control unit 400 includes a cooling unit 410 and a heating unit 420, which can achieve precise control of the temperature in the reaction kettle. The cooling unit 410 includes a liquid storage tank 4101. A collector 4102 is provided at the top of the liquid storage tank 4101. Four first liquid outlet pipes 4103 are provided at the top of the collector 4102. The liquid inlet ends of the first liquid outlet pipes 4103 extend into the heat conduction cavity respectively and are provided with a plurality of heat conduction pipes 4104. The plurality of heat conduction pipes 4104 are arranged up and down and are connected end to end through a connecting pipe 4105. A plurality of pumps 1 4107 are provided on the bearing frame 100. The liquid inlet of the pump 1 4107 is connected to the liquid storage tank 4101 through a pipe 1 4108. The to-be-tested liquid outlet of the pump 1 4107 is connected to the heat conduction pipe 4104 through a first liquid inlet pipe 4106. The coolant is conveyed to the heat conduction pipe 4104 through the pump 1 4107 to realize the cooling of the reaction kettle.

[0031] Furthermore, a spiral pipe 4109 is arranged in the heat-conducting cavity at the bottom. The liquid outlet end of the spiral pipe 4109 extends below the heat-insulating kettle body 201 and is provided with a second liquid outlet pipe 4110. The end of the second liquid outlet pipe 4110 is connected to the liquid storage tank 4101. The liquid inlet end of the spiral pipe 4109 extends below the heat-insulating kettle body 201 and is provided with a second liquid inlet pipe 4111. A second pump body 4112 is arranged at the end of the second liquid inlet pipe 4111. The second pump body 4112 is connected to the liquid storage tank 4101 through a second pipe 4113. A cooler is arranged in the liquid storage tank 4101 to further enhance the cooling effect.

[0032] It should be noted that the heating unit 420 and the cooling unit 410 have the same structure. The difference is that a heater is arranged in the liquid storage tank 4101 of the heating unit 420. With the cooperation of the heating unit 420 and the cooling unit 410, independent temperature control of different areas of the inner kettle body 204 can be achieved, accurately controlling the temperature of each area, ensuring that the adhesive reaction proceeds as expected, optimizing the product quality, improving the energy utilization efficiency, reducing the production cost, and extending the service life of the equipment. Temperature has a crucial impact on the performance of the adhesive. If the temperature in the reaction kettle is uneven, it may lead to inconsistencies in the degree of polymerization, cross-linking degree, etc. of different parts of the adhesive, thus affecting the quality stability and performance uniformity of the product. Independent temperature adjustment can ensure that the temperature of each area in the reaction kettle is accurately controllable, enabling the adhesive to react at an appropriate temperature throughout the reaction process, thereby ensuring the stable product quality and improving the performance indicators of the product, such as bonding strength, water resistance, heat resistance, etc., enhancing the competitiveness of the product in the market.

[0033] The workflow of this embodiment is as follows: When preparing the adhesive, the raw materials of the adhesive are put into the reaction kettle through the feeding pipeline 203. The motor 301 is started, and the motor 301 drives the drive shaft 302 to rotate, thereby enabling the first stirring member and the second stirring member to start working. The inclined blade stirring pieces 307 and the notches 308 of the first stirring member stir and shear the materials, and the lower scraping blade 305 and the side scraping blade 312 clean the materials at the bottom and the side wall of the kettle body. The stirring blade one 314, the guide cylinder 315 and the stirring blade two 316 of the second stirring member make the materials form a complex flow path and are fully mixed. At the same time, according to the requirements of the reaction, the temperature in the reaction kettle is regulated by the independent temperature control unit 400. If heating is required, the heating unit 420 is started to heat the heat-conducting oil. If cooling is required, the cooling unit 410 is started, and the pump body one 4107 transports the coolant to the heat-conducting pipe 4104 to cool the reaction kettle. During the reaction process, by observing parameters such as the temperature and pressure in the reaction kettle, the stirring speed and the temperature control parameters are adjusted in a timely manner to ensure that the reaction proceeds under the best conditions. After the reaction is completed, the operation of the motor 301 and the independent temperature control unit 400 is stopped, the valve of the discharge pipeline 211 is opened, and the generated adhesive is discharged from the reaction kettle. After the discharging is completed, the reaction kettle is cleaned, and an appropriate amount of cleaning liquid can be added into the reaction kettle.
