Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a reaction kettle for binder production with waste heat utilization. Background Technique

[0002] During the production process of adhesives, a large amount of heat is easily generated when solid raw materials are stirred and mixed with liquid solutions. This heat causes the body of the reaction kettle to overheat and the gas inside the reaction kettle to expand.

[0003] In the prior art, in order to avoid too high air pressure in the reaction kettle, the heat is usually absorbed by circulating water flow and then dissipated to the outside, so as to play a role in heat dissipation. However, due to direct heat dissipation, this part of the heat will be wasted. Some existing devices will use water flow to recover heat, but due to certain limitations in the heat absorption capacity of water, it is necessary to frequently replace the water, which is rather troublesome. Therefore, it is necessary to design a reaction kettle for binder production with waste heat utilization to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to provide a reaction kettle for binder production with waste heat utilization. The reaction kettle uses a water pump to circulate water between the reaction kettle and the mixing tank, and a spiral tube is arranged on the spiral blade, so that the raw materials can better absorb the heat in the water, and the raw materials after heat absorption can be irregularly thrown on the upper surface of the raw materials, so that the preheated raw materials can be distributed as evenly as possible.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] Preferably, the rotating rod is drivingly connected to the two vertical pipes through a transmission assembly. The transmission assembly includes a first transmission wheel arranged on the rotating rod, and second transmission wheels are arranged on both of the two vertical pipes. The first transmission wheel is drivingly connected to the two second transmission wheels through a transmission belt.

[0009] Preferably, two cylinders are fixedly connected to the inner bottom of the mixing tank.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figures 1 - 3 A reaction kettle for adhesive production with waste heat utilization, including a kettle body 1, two dropping pipes 5 are fixedly connected to the upper end of the kettle body 1, and a valve is provided on the dropping pipe 5. The upper ends of the two dropping pipes 5 are fixedly connected to a mixing tank 6. The two ends of the two dropping pipes 5 are respectively connected to the mixing tank 6 and the kettle body 1. An annular cylinder is fixedly connected to the inside of the kettle body 1, and the annular cylinder is filled with water. A serpentine tube 13 is provided in the annular cylinder. A pump body 2 is installed on the right side of the kettle body 1. The liquid outlet end of the serpentine tube 13 is connected to the liquid inlet end of the pump body 2. A fixed plate is installed on the upper end of the mixing tank 6. 7. Removable sealing plates are provided on the front and rear sides of the fixed plate 7 to facilitate subsequent cleaning of the mixing tank, and an addition port is provided on the sealing plate. Two first rotary joints 10 are provided on the fixed plate 7. The upper ends of the two first rotary joints 10 are connected to the liquid outlet end of the pump body 2 through the liquid outlet pipe 4. The lower ends of the two first rotary joints 10 are connected to vertical pipes 16. Two second rotary joints 15 are installed at the lower end of the mixing tank 6. The two vertical pipes 16 are connected to the upper end of the second rotary joint 15, and the lower ends of the two second rotary joints 15 are connected to the annular cylinder.

[0021] Among them, a driving motor 8 is installed at the upper end of the fixed plate 7, and the end of the output shaft of the driving motor 8 passes through the fixed plate 7 and is fixedly connected to a rotating rod 18. A plurality of stirring rods are fixedly connected to the outer wall of the rotating rod 18. The rotating rod 18 is connected to the two vertical pipes 16 through a transmission assembly. The transmission assembly includes a first transmission wheel arranged on the rotating rod 18, and a second transmission wheel is provided on each of the two vertical pipes 16. The first transmission wheel and the two second transmission wheels are connected through a transmission belt. The radius of the first transmission wheel is twice the radius of the two second transmission wheels.

[0022] Among them, two cylinders are fixedly connected to the inner bottom of the mixing tank 6, two vertical pipes 16 pass through the cylinders, and the outer walls of the two vertical pipes 16 are fixedly connected with spiral blades 17. The inner bottoms of the two cylinders are provided with rectangular openings, and the two spiral blades 17 are provided with spiral tubes 9. The two spiral tubes 9 are respectively connected to the corresponding vertical pipes 16.

[0023] Wherein, a rotating disk 11 is provided on the outer wall of the cylinder. The rotating disk 11 is communicated with the outer wall of the corresponding vertical pipe 16 through a fixing rod 12, and both rotating disks 11 are arranged obliquely downward.

[0024] The function principle of the present utility model can be elaborated through the following operation method: First, pour the raw materials heated by the existing technology into the mixing tank 6 for mixing, and then send the raw materials into the kettle body 1 through the two feeding pipes 5 for reaction. At this time, close the valves on the two feeding pipes 5, and at the same time add new raw materials into the mixing tank 6. At this time, a large amount of heat will be generated during the reaction of the raw materials in the reaction kettle, which will be absorbed by the water in the annular cylinder, causing the water temperature to rise.

[0025] Start the pump body 2 and the driving motor 8, so that the water in the annular cylinder enters the serpentine pipe 13 and then enters the two vertical pipes 16 through the pump body 2, and then flows in the two spiral pipes 9, and then returns to the mixing tank 6.

[0026] The rotation of the driving motor 8 will drive the rotating rod 18 and the two vertical pipes 16 to rotate, thereby mixing the raw materials. At the same time, the rotation of the two vertical pipes 16 will drive the spiral blades 17 to rotate, so that the materials at the bottom can be continuously conveyed upward, so that only a small amount of materials come into contact with the spiral pipe 9 each time, so that more heat in the spiral pipe 9 can be absorbed. At the same time, the conveyed materials will fall on the two rotating disks 11. Since the rotating disks 11 are in a rotating state, under the action of centrifugal force, the preheated materials can be dispersed at various positions in the mixing tank 6, so that the preheated raw materials can contact the raw materials in other different areas, so that the raw materials can be evenly heated.

[0027] It is worth mentioning that the present utility model mainly uses the heat generated during production to preheat the raw materials. However, in actual use, the raw materials can be heated by the existing technology according to the preheating situation, so that the raw materials can reach the appropriate reaction temperature in the reaction kettle.

[0028] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
