[0021] Embodiment 1

[0023] The preheating assembly includes preheating pipe 502 spirally wound on jacket 2, one end of preheating pipe 502 close to air outlet 4 penetrates through jacket 2, feeding pipe 501 is fixedly connected to one end of preheating pipe 502 close to air outlet 4, feeding pipe 501 is connected to feeding pipe 104 at the end away from preheating pipe 502, avoiding cavity 503 is arranged in kettle cover 102, discharging pipe 504 is arranged in avoiding cavity 503, one end of discharging pipe 504 is connected to feeding pipe 104, the other end of discharging pipe 504 is connected to one end of preheating pipe 502 close to air inlet 3, feeding pipe 104 is provided with control assembly for controlling the preheating temperature of mixed raw materials;

[0024] It should be noted here that: through the setting of the preheating assembly, the heat utilization and heat generation of the water-based adhesive production raw materials in the mixing and reaction process are used to preheat the raw materials, thereby achieving effective use of energy while improving the reaction activity and reaction speed of the raw materials in the kettle body 101 and the dispersion uniformity of part of the viscous raw materials, thereby improving the mixing effect of the raw materials, and further ensuring the product quality and stability in the water-based adhesive production process.

[0025] Please refer to Figure 5 , the inner wall of the feeding pipe 104 in the drawing is fixedly connected with a baffle 505, and the baffle 505 is located between the feeding port of the feeding pipe 501 and the discharging port of the discharging pipe 504.

[0026] It should be noted here that: through the setting of the baffle 505, the flow direction of the raw materials is blocked and guided.

[0027] Please refer to Figure 5 , the control assembly in the drawing includes a first control plate 601 arranged in the feeding pipe 104, the first control plate 601 is connected with the discharging port of the discharging pipe 504, the first control plate 601 is provided with a plurality of first control holes 602, and the side of the first control plate 601 away from the discharging pipe 504 is rotatably connected with a second control plate 603, the second control plate 603 is provided with a plurality of second control holes 604, and the feeding pipe 104 is provided with a driving assembly for driving the second control plate 603.

[0028] It should be noted here that: through the setting of the control assembly, the temperature of the raw material preheating can be effectively adjusted and controlled according to the temperature of the kettle body 101, thereby improving the flexibility of the raw material preheating.

[0029] Working principle: when using the reaction kettle to produce and process water-based adhesive, first, use the high-pressure pump to deliver the raw materials (mainly liquid raw materials, part of the solid raw materials will be pre-dissolved or dispersed before being put into the kettle body 101) into the feeding pipe 104, and then under the blocking and guiding action of the baffle 505, flow to the feeding pipe 501, and under the action of pressure, flow to the preheating pipe 502. Since the reaction kettle will preheat the kettle body 101 when producing and processing water-based adhesive, high-temperature steam will be delivered into the jacket 2 through the air inlet hole 3, thereby achieving preheating of the kettle body 101 while heating the raw materials with the preheating pipe 502 spirally wound in the jacket 2. The heated raw materials will flow from the discharging pipe 504 into the feeding pipe 104 and eventually into the kettle body 101.

[0030] After the preheated raw materials enter into the kettle body 101, the stirring motor 103 can be used to drive the stirring blades to mix and stir the raw materials, so as to react and mix the raw materials. The preheated raw materials can be rapidly heated in the kettle body 101 due to the initial temperature, thereby improving the reactivity and reaction speed of the raw materials. The preheating of the raw materials can help to reduce the viscosity of some viscous raw materials, thereby improving the diffusion capacity of the raw materials, and improving the uniformity of the dispersion of the raw materials in the kettle body 101, thereby improving the mixing effect of the raw materials, and ensuring the product quality and stability in the production process of the water-based adhesive.

[0031] Since heat is generated during the mixing and stirring of the raw materials, the delivery of high-temperature steam can be stopped when the temperature inside the kettle body 101 reaches a certain level. At this time, the high temperature generated inside the kettle body 101 is adsorbed and taken away by the raw materials, thereby achieving preheating of the raw materials while reducing the consumption of cooling gas. It should be noted that if the temperature inside the kettle body 101 is too high, or the raw materials have limited adsorption of high temperature, or the raw materials have been completely delivered, cooling gas needs to be delivered to cool the kettle body 101. Even if the cooling gas is delivered into the jacket 2 to cool the mixed raw materials inside the kettle body 101 (the temperature range of the polymerization reaction is usually controlled at 50-90℃), the preheating of the raw materials before delivery can be achieved under the action of residual heat.

[0032] When the temperature inside the kettle body 101 is too high or too low, the preheating temperature can be controlled by adjusting the delivery speed of the raw materials. During the preheating temperature control of the raw materials, the second control plate 603 is driven to rotate by the cooperation of the driving assembly and the connecting assembly, and the flow time of the raw materials in the preheating pipe 502 is controlled by adjusting the staggered amount between the second control hole 604 on the second control plate 603 and the first control hole 602 on the first control plate 601, thereby achieving the control of the preheating temperature of the raw materials. Therefore, the preheating temperature of the raw materials can be effectively adjusted and controlled according to the temperature of the kettle body 101, thereby improving the flexibility of the preheating of the raw materials.

The feeding pipe 104 is provided with an indicating assembly for indicating the rotation angle of the driving rod 701.

[0035] It should be noted that, through the driving assembly, the rotation of the driving ball 705 will drive the worm 702 on the driving rod 701 to rotate. Under the meshing transmission action of the worm 702 and the worm wheel 703, the connecting rod 704 is driven to rotate. Then, under the connecting action of the connecting assembly, the second control plate 603 is driven to rotate.

The first transmission tooth 802 and the second transmission tooth 803 are connected through a tooth belt 804.

[0037] It should be noted that, through the connecting assembly, the transmission action between the first transmission tooth 802, the second transmission tooth 803 and the tooth belt 804 is utilized to realize the connecting transmission between the connecting rod 704 and the mounting rod 801. Then, the rotation of the second control plate 603 is adjusted and controlled.

[0040] It should be noted that, through the indicating assembly, the reference action of the indicating plate 902 and the indicating groove 901 is utilized to detect and control the rotation angle of the driving rod 701. Then, the reference for adjusting the staggered amount between the first control hole 602 and the second control hole 604 is provided.
