Description

Technical Field

[0001] The utility model belongs to the technical field of coating and adhesive production, and particularly relates to a high-viscosity glue liquid dispersion kettle. Background Art

[0002] In the production process of fine chemicals, such as the coatings and adhesives industries, the disperser is an important processing equipment. By placing the raw materials in the disperser, they are completely mixed and modified to form materials with certain properties for use. The raw materials in the disperser are mainly sheared, impacted, crushed, and dispersed by the stirring paddle, and finally passed through the stirring device to achieve the purpose of uniform mixing.

[0003] The utility model with publication number CN218981573U discloses a reactor with enhanced mixing function, whose main working structure includes a reactor body, a stirring chamber, a stirring paddle, a liquid dispersion mechanism and a circulation pump. During operation, the material enters the stirring chamber from the first feed port and is preliminarily stirred and mixed by the stirring paddle. Subsequently, the circulation pump extracts the bottom material and disperses it again into the stirring chamber through the liquid dispersion mechanism. The liquid dispersion mechanism consists of upper and lower dispersion plates. The material is pressed into a thin-walled fan shape in the dispersion gap and flows out along the edge, thereby achieving sufficient contact and mixing. At the same time, vacuum is drawn through the vacuum valve to achieve a degassing effect, which improves the uniformity of material mixing and the degassing efficiency and shortens the production cycle. However, the reactor with enhanced mixing function lacks cleaning and washing for the inside of the reactor. After long-term use, residual materials and dirt will accumulate in the stirring chamber and the liquid dispersion mechanism, affecting the quality of subsequent products and the life of the equipment.

[0032] A first feed port 11 and a second feed port 12 are provided on the top of the kettle body 1 , and a first discharge port 13 is provided on the bottom of the kettle body 1 .

[0033] The stirring mechanism 2 includes a first stirrer 21 and a pair of second stirrers 22 disposed oppositely around the first stirrer 21. The first stirrer 21 includes a first stirring shaft 211 and a telescopic stirring frame 212 sleeved on the bottom of the first stirring shaft 211. The second stirrer 22 includes a second stirring shaft 221, a stirring paddle 222 disposed on the second stirring shaft 221, and a lifting unit 25 for controlling the vertical movement of the second stirring shaft 221.

[0034] The telescopic stirring frame 212 provided on the first stirrer 21 and the lifting unit 25 provided on the second stirrer 22 control the stirring coverage of the first stirrer 21 and the second stirrer 22, so that the mixed material is mixed more thoroughly in the kettle body 1. When it is necessary to clean the residual glue on the inner wall of the kettle body 1, the lifting unit 25 controls the second stirrer 22 to rise, and at the same time, the telescopic stirring frame 212 is expanded to clean the residual glue on the inner wall of the kettle body 1.

[0035] like Figure 3 、 Figure 4 As shown, in this embodiment, the telescopic stirring frame 212 includes an inner frame 2121 sleeved on the bottom of the first stirring shaft 211, an outer frame 2122 arranged opposite to the inner frame 2121, and a plurality of elastic telescopic parts 2123.

The liquid-increasing mechanism 3 includes a liquid inlet pipe 30, an elevated tank 31, a third feed port 32 disposed at the upper end of the elevated tank 31, and a fourth feed port 33 disposed at the upper end of the elevated tank 31. One end of the liquid inlet pipe 30 is connected to the elevated tank 31 by a pipe, and the other end is connected to the second stirring shaft 221 by a pipe. When liquid needs to be added or cleaned within the kettle body 1, solvent is added to the third feed port 32, while nitrogen is introduced to the fourth feed port 33 to maintain pressure.

[0039] like Figure 2 As shown, in this embodiment, the liquid inlet pipe 30 is provided with a first pneumatic valve 34, a second pneumatic valve 35, a third pneumatic valve 36, and a weighing module sensor 37 disposed at the bottom of the header tank 31. The first pneumatic valve 34 is located near the header tank 31, the second pneumatic valve 35 is located near one second stirring shaft 221, and the third pneumatic valve 36 is located near the other second stirring shaft 221. The weighing module sensor 37 and the first, second, and third pneumatic valves 34, 35, and 36 precisely control the amount and pressure of solvent added, achieving quantitative liquid addition and spray cleaning.

[0040] like Figure 3 As shown, in this embodiment, three stirring paddles 222 are provided on the second stirring shaft 221 along the axial direction, so as to increase the intensity and uniformity of stirring of the second stirrer 22 in the axial direction.

[0041] In this embodiment, the structure of the stirring paddle 222 adopts a dispersion disk type, which has a strong dispersion effect on the material.

[0042] like Figure 3 As shown, in this embodiment, a reducer 24 is provided on the top of the first agitator 21 and the second agitator 22 , and a motor 23 is provided above each reducer 24 . The motor 23 provides rotational power for the first agitating shaft 211 and the second agitating shaft 221 .

[0043] like Figure 1 、 Figure 2 As shown, in this embodiment, a jacket 4 is provided around the side of the kettle body 1. The jacket 4 is hollow. The jacket 4 is provided with a medium inlet 41 and a medium outlet 42. During stirring, a cooling medium or a heating medium is introduced into the medium inlet 41 to control the temperature inside the kettle body 1.

[0044] Example 2

[0045] Different from the embodiment 1, the stirring paddle 222 in this embodiment adopts a turbine-type structure, and the turbine-type stirring paddle has a higher shear force.

[0046] When the present invention is used, resin, solvent, curing agent, filler, additive, and various materials are first added to the first feed port 11. At this time, the bottom stirring paddle 222 of the second stirrer 22 is flush with the telescopic stirring frame 212 of the first stirrer 21. The motor 23 is started to control the operation of the first stirrer 21 and the second stirrer 22, so that the materials are stirred and mixed in the kettle body 1. According to the process temperature requirements, a cooling source or a heating source medium is introduced into the medium inlet 41, and the cooling source or the heating source medium flows out from the medium outlet 42 to control the temperature in the kettle body.

[0047] The cylinder 252 controls the piston rod 253, which drives the limit frame 254 and the second stirring shaft 221 to rise, raising the position of the second agitator 22. At this point, the distance between the bottom stirring paddle 222 of the second agitator 22 and the upper frame of the telescopic stirring frame 212 of the first agitator 21 is 6-10 cm. Simultaneously, the motor 2124 controls the telescopic member 2123 to expand. After expansion, the frame 2122 of the telescopic stirring frame 212 is 0.5-1 cm away from the inner wall of the kettle body 1, fully mixing the materials inside the kettle body 1 and scraping and cleaning the inner wall of the kettle body 1.

[0048] Add solvent to the third feed port 32 of the high-level tank 31, and introduce nitrogen into the fourth feed port 33 of the high-level tank 31 to maintain pressure. Through the weighing module sensor 37, the first pneumatic valve 34, the second pneumatic valve 35, and the third pneumatic valve 36 are interlocked to allow the solvent to enter the second stirring shaft 221 of the second agitator 22 along the liquid inlet pipe 30, and be sprayed from the liquid guide hole 223 to the inner wall of the kettle body 1 and the stirring paddle 222, thereby realizing quantitative liquid addition and spray cleaning.

[0049] When the stirring and dispersion is completed, nitrogen is introduced into the second feed port 12 to maintain the pressure, so that the high-viscosity glue inside the kettle body 1 is quickly discharged from the first discharge port 13 at the lower part of the kettle body 1. At the same time, solvent is added to the third feed port 32 of the header tank 31 again, and nitrogen is introduced into the fourth feed port 33 of the header tank 31 to clean the interior of the kettle body 1.

[0050] The above description is based on the ideal embodiment of the present invention.
