Technical Field
[0001] The utility model relates to the technical field of latex production, in particular to a latex reaction kettle. Background Art
[0002] Emulsion adhesive (latex) is an environmentally friendly glue; compared with traditional solvent-based glue, it uses pure water instead of solvents (toluene, ethyl acetate), reducing the use of fossil resources and eliminating the harm of solvents to the environment and the body, thus achieving the purpose of saving resources and reducing costs.
[0003] In the production process of latex, many chemical raw materials need to be fully mixed and stirred and reacted in a reactor, and corresponding catalysts are added at the same time, under specific temperature conditions. Existing latex reactors are usually equipped with a thermostat on the side wall of the reactor body to adjust the temperature inside the reactor body, but this temperature regulation method has a slow adjustment speed, which affects production efficiency. At the same time, due to the high viscosity of latex, latex is easy to adhere to the agitator during the production and stirring process. Usually, the agitator can only be disassembled to clean the accumulated material, which is not very convenient. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the utility model aims to provide a latex reactor which can adjust the temperature quickly and is convenient for cleaning the accumulated materials.

[0007] As a preferred solution, the lower end of the kettle body is in a hemispherical structure, and a circular ring bracket is connected to the outer surface of the lower end of the kettle body, and a plurality of supporting legs are arranged at the bottom of the circular ring bracket.
[0008] As a preferred solution, a containing cavity which surrounds the stirrer is provided in the stirrer, and the containing cavity is communicated with the inner cavity of the stirring shaft; a heating tube is passed through the inner cavity of the stirring shaft and the containing cavity of the stirrer.
[0009] As a preferred solution, the liquid inlet end of the heating tube extends from the lower end of the stirring shaft and is used to be connected to the hot water tank, and the liquid outlet end of the heating tube passes through the accommodating chambers of each stirrer in turn and then extends from the lower end of the stirring shaft.
[0010] As a preferred solution, temperature regulating tubes are arranged at intervals above and below the inner wall of the kettle body.
[0011] As a preferred solution, the agitator is disc-shaped, and the middle of the upper surface of the agitator is a connecting portion for connecting to the agitator shaft. The connecting portion is in a cone shape with an opening facing upward, and a water leakage hole is provided at the lowest position of the connecting portion.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0023] Example 1: Figures 1 to 3 As shown, a latex reactor comprises a reactor body 1, the upper end surface of the reactor body 1 is connected with a feed pipe 2, the bottom of the reactor body 1 is connected with a discharge pipe 3, the upper end of the reactor body 1 is provided with a funnel 4 with an arc-shaped inner cavity, and the middle part of the funnel 4 is provided with a water inlet; a motor 5 is provided below the reactor body 1, the motor 5 drives a stirring device 6, the stirring device 6 comprises a stirring shaft 61 which is installed inside the reactor body 1 and is in the shape of a hollow column, a bearing is provided at the connection between the stirring shaft 61 and the reactor body 1, an agitator 62 is horizontally provided on the stirring shaft 61, at least two agitators 62 are arranged at intervals from top to bottom, wherein the projection of the edge of the upper agitator 62 falls into the lower agitator 62.
[0024] During implementation, the upper end surface of the kettle body 1 is also connected with a water inlet pipe 40 , and the water inlet pipe 40 is connected to the funnel 4 .
[0025] During implementation, the funnel also includes a funnel cover that is detachably mounted on the top of the funnel, and a handle is provided in the middle of the upper surface of the funnel cover to facilitate dust prevention of the funnel when it is not in use.
[0026] In this embodiment, when the agitator needs to be cleaned, water is added to the funnel, so that water enters the kettle body from the water inlet of the funnel and flushes the agitator. The water on the upper agitator can fall from the edge into the lower agitator for flushing, which can solve the problem of being inconvenient to clean the agitator below from top to bottom. At the same time, the water in the upper agitator flows downward from the edges on all sides, and the water has good dispersion when flowing downward, which can improve the flushing efficiency.
[0027] During implementation, the flushed wastewater can be discharged to the outside through the discharge pipe.
[0028] Specifically, the lower end of the kettle body 1 is a hemispherical structure, and a circular ring bracket 7 is connected to the outer surface of the lower end of the kettle body 1 , and a plurality of supporting legs 71 are arranged at the bottom of the circular ring bracket 7 .
[0029] During implementation, a rubber layer is provided on the inner side of the circular ring bracket 7 to reduce the noise generated by the vibration of the kettle body 1 .
[0030] Specifically, the stirrer 62 is provided with a containing cavity which surrounds the stirrer 62 , and the containing cavity is communicated with the inner cavity of the stirring shaft 61 ; the heating tube 63 is penetrated in the inner cavity of the stirring shaft 61 and the containing cavity of the stirrer 62 .
[0031] During implementation, the accommodating chamber of the stirrer 62 is provided with two symmetrical openings, and the heating tube 63 enters the accommodating chamber of the stirrer 62 from one of the openings and leaves the accommodating chamber of the stirrer 62 from the other opening.
[0032] In this embodiment, while the agitator rotates along with the stirring shaft to stir, the heating tube inside the agitator will also heat the latex. Since the agitator rotates around the axis of the stirring shaft, the latex inside the kettle can be heated more evenly, so that the latex inside the kettle maintains uniform heat.
[0033] Specifically, the liquid inlet end of the heating tube 63 extends from the lower end of the stirring shaft 61 and is used to be connected to a hot water tank (not shown), and the liquid outlet end of the heating tube 63 passes through the accommodating cavities of each stirrer 62 in turn and then extends from the lower end of the stirring shaft 61.
[0034] Specifically, the inner wall of the kettle body 1 is provided with temperature regulating tubes 8 at intervals in the upper and lower parts. The temperature regulating tubes 8 are extended along the circumference of the kettle body 1 , and hot water is provided inside the temperature regulating tubes 8 .
[0035] In this embodiment, the heating tube passed through the agitator and the agitator shaft can quickly heat the latex in the middle position of the kettle body, while the temperature regulating tube installed on the inner wall of the kettle body can quickly heat the latex at the outer edge of the kettle body. This can make the temperature of all the latex in the kettle body more quickly adjustable, thereby improving the production efficiency of the latex.
[0036] Specifically, the stirrer 62 is disc-shaped, and the middle of the upper surface of the stirrer 62 is a connecting portion 64 for connecting to the stirring shaft 61 . The connecting portion 64 is in a cone shape with an opening facing upward, and a water leakage hole 65 is provided at the lowest position of the connecting portion 64 .
[0037] During implementation, there are at least two water leakage holes 65 symmetrically arranged.
[0038] In this embodiment, before the water from the upper agitator flows into and flushes the lower agitator from the periphery, the water leakage hole can leak water first to flush the lower agitator in advance; at the same time, after the accumulated material is cleaned, all the liquid on the agitator can leak out through the water leakage hole to avoid accumulation of liquid on the agitator.
[0039] Specifically, the upper end of the stirring shaft 61 is in a spherical cap structure and is directly opposite to the water inlet of the funnel.
[0040] In this embodiment, after water hits the spherical cap structure of the stirring shaft, it enters and flushes the stirrer more evenly.
[0041] Specifically, a driven gear 66 is sleeved on the outer surface of the lower end of the stirring shaft 61 , and a driving gear 51 is sleeved on the output shaft of the motor 5 , and the driving gear 51 is meshed with the driven gear 66 .
[0042] It should be noted that, in the present embodiment, each type of pipeline is correspondingly configured with a switch, and the specific structure of the switch is not the focus to be protected by the present application and will not be elaborated here.
[0043] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
