Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a glue making reaction kettle. Background Art

[0002] The glue making reactor is a reaction vessel widely used in industrial production. The glue making reactor is mainly composed of the following parts: Reactor body: usually made of high temperature resistant materials such as stainless steel, with good corrosion resistance and pressure resistance. Outer coil: It is wrapped around the outside of the reactor body and is used to inject heat transfer medium (such as hot oil) into the pipeline, and exchange heat with the material in the reactor through the pipeline. Heat transfer medium: used to flow in the outer coil to transfer heat to the material in the reactor so that it reaches the required reaction temperature. Agitator: used to evenly stir the material in the reactor to ensure the uniformity and sufficiency of the reaction. Feed port, discharge port, exhaust port: used to add reactants to the reactor, take out reaction products and exhaust gas respectively.

[0003] In the glue making technology, the reactor needs to heat up quickly. Since most of the existing glue making reactors use the design characteristics of external coils, their heat exchange area may be smaller than other types of reactors, which limits their heat exchange efficiency and heating speed. In the glue making process that requires rapid heating, it may not meet the demand for efficient heat exchange. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model provides a glue making reactor, which has a larger heat transfer area and can increase the turbulence of the fluid in the coil, so that the heat transfer efficiency is higher.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A glue making reactor, comprising:

[0007] A kettle body, on which a driving member, a feed inlet and a discharge outlet are arranged;

[0008] The coil is spirally arranged on the outer circumference of the kettle body;

[0009] The bottom pipe is arranged at the bottom end of the kettle body, the upper ends of a plurality of bottom pipes are connected with the lower end of the coil, and the lower ends of a plurality of bottom pipes are connected with each other.

[0010] Furthermore, the bottom tube is arranged along the radial direction of the kettle body, and a plurality of bottom tubes are evenly distributed in a circle relative to the axis of the kettle body.

[0011] Furthermore, a medium inlet is provided at the upper end of the coil.

[0012] Furthermore, a bottom ring is provided at the bottom end of the kettle body, the bottom ring is located at the outer periphery of the discharge port, and the lower end of the bottom pipe is connected to the bottom ring.

[0013] Furthermore, a medium outlet is provided at the lower end of the bottom ring.

[0014] Furthermore, the inner diameter of the coil is varied.

[0015] Furthermore, the coil is formed by connecting a first connecting pipe and a second connecting pipe, and the first connecting pipe and the second connecting pipe have different inner diameters.

[0016] Furthermore, the first connecting pipe and the second connecting pipe have the same outer diameter.

[0017] Furthermore, the kettle body is provided with a support member, and a pressure sensor is provided on the support member.

[0018] Beneficial effects of the utility model:

[0019] (1) A spiral coil is arranged on the outer circumference of the kettle body, and a bottom pipe evenly distributed around the circumference is arranged at the bottom of the kettle body. The coil and the bottom pipe transfer heat to the kettle body together, and the heat transfer area is larger.

[0020] (2) Using a more reasonable coil shape can increase the turbulence of the fluid in the coil and improve the heat transfer efficiency.

[0021] (3) The coil adopts a variable diameter method. When the heat transfer medium flows through coils of different diameters, turbulence will be generated due to the change in the coil diameter. Turbulence can form a diffusion channel and increase the dimension of the flow. The transfer rate of momentum, heat and mass caused by random motion in turbulence is several orders of magnitude higher than that of laminar flow. Therefore, these turbulent flow fields accelerate the efficiency of heat transfer.

[0022] (4) It has a weighing function and can monitor the weight of the material in the kettle at all times. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The utility model is further described in detail below with reference to the accompanying drawings.

[0031] A glue making reactor comprises a reactor body 1, on which a feed port 3 and a discharge port 4 are arranged. A driving member 2 is also arranged on the reactor body 1, and the driving member 2 can drive a stirrer in the reactor body 1. A support member 8 is arranged at the lower end of the reactor body 1, and the reactor body 1 is fixed to the ground through the support member 8. A pressure sensor 9 is arranged on the support member 8, and the pressure sensor 9 can monitor the quality of the material in the reactor body 1.

[0032] The outer peripheral wall of the kettle body 1 is provided with a spiral coil 5, and the bottom end of the kettle body 1 is provided with a plurality of bottom tubes 6, which are arranged along the radial direction of the kettle body 1, and are evenly distributed in a circle relative to the axis of the kettle body 1. The upper ends of the plurality of bottom tubes 6 are connected with the lower end of the coil 5, and the bottom end of the kettle body 1 is provided with a bottom ring 7, which is located at the outer periphery of the discharge port 4, and the lower end of the bottom tube 6 is connected with the bottom ring 7. The upper end of the coil 5 is provided with a medium inlet 10. The lower end of the bottom ring 7 is provided with a medium outlet 11. The heat transfer medium enters the coil 5 from the medium inlet 10 at the upper end of the coil 5, then enters the bottom tube 6 from the lower end of the coil 5, and then enters the bottom ring 7 from the lower end of the bottom tube 6, and finally flows out from the medium outlet 11 at the lower end of the bottom ring 7. The coil 5 and the bottom tube 6 achieve a more comprehensive coating of the kettle body 1, which significantly increases the heat exchange area. The bottom ring 7 is located at the outer periphery of the discharge port 4, and can carry out targeted and focused heating on the discharge port 4. Maintaining the high temperature of the discharge port 4 can facilitate the discharge operation.

[0033] While increasing the heat exchange area, it is also necessary to improve the heat transfer efficiency. The technical solution of this invention is to increase the heat transfer efficiency by using turbulence. Specifically, a coil 5 with a changing inner diameter is used. The coil 5 adopts a variable diameter method. When the heat transfer medium flows through the coil 5 with different diameters, turbulence will be generated due to the change in the diameter of the coil 5. Turbulence can form a diffusion channel and increase the dimension of the flow. The transfer rate of momentum, heat and mass caused by the random motion in turbulence is several orders of magnitude higher than that of laminar flow, so these turbulent flow fields accelerate the efficiency of heat transfer.

[0034] An annular groove may also be provided on the coil 5, or a curved flow-guiding structure may be provided inside the coil 5, so as to achieve the technical effect of turbulence.

[0035] In a specific implementation, the coil 5 can directly adopt a reducer or a corrugated tube, and the coil 5 can also be formed by connecting a first connecting pipe 51 and a second connecting pipe 52 with different inner diameters. The first connecting pipe 51 and the second connecting pipe 52 are arranged alternately. When the heat transfer medium flows through the alternately arranged first connecting pipe 51 and the second connecting pipe 52, turbulence can also be generated to accelerate the heat transfer efficiency.

[0036] In order to facilitate the welding operation, the first pipe 51 and the second pipe 52 have the same outer diameter, so that it is easy to align and weld the first pipe 51 and the second pipe 52 from the outside, and the appearance is more neat and beautiful.

[0037] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
