Description

Technical Field

[0001] This utility model relates to the field of reaction equipment technology, and in particular to a reaction vessel for adhesives. Background Technology

[0002] An adhesive reaction vessel is a key piece of equipment used in adhesive production. It is mainly used to realize the functions of material mixing, reaction, heating, and cooling in the adhesive production process.

[0003] The principle is that, driven by the power unit, the agitator rotates in a fixed direction, causing the material to rotate axially and radially, so that the material in the container has both axial and circumferential motion at the same time, thereby generating shearing and diffusion mixing effects, and realizing rapid mixing and blending of the material.

[0004] The height of the stirrers in existing adhesive reaction vessels is fixed. However, this design results in a certain distance between the bottom of the stirrer and the bottom of the vessel during the stirring process. This distance prevents the stirrer from effectively acting on the sediment layer in the early stages of stirring, which may lead to the solid raw materials not being fully dissolved or dispersed. In the middle stage of the reaction, the fixed position of the stirrer may result in the stirrer being too low or too high, which may affect the quality of the raw materials after the reaction. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes a reaction vessel for adhesives to more accurately resolve these issues.

[0006] This utility model is achieved through the following technical solution:

[0009] Furthermore, the present invention provides a limiting slider on the inner side of the upper end face of the support frame, and limiting grooves that cooperate with the limiting slider are provided at the front and rear ends of the support frame.

[0010] Furthermore, the present invention provides a hanging end on the connecting frame and located on both sides of the mounting frame, and a connecting block on the top of the top cover and located on both sides of the connecting groove, wherein a hanging ring that cooperates with the hanging end is hinged on the connecting block.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example

[0023] refer to Figure 1-5 An adhesive reaction vessel includes a vessel body 1, a top cover 2 disposed on the vessel body 1 and connected to the flange of the vessel body 1, and a connecting groove 21 opened at the top of the top cover 2. The vessel body 1 is provided with H-shaped support frames 3 on both sides. The lower end face of the support frame 3 is provided with a lifting member 31. The output end of the lifting member 31 passes through the support frame 3 and is connected to a connecting frame 32. The bottom middle of the connecting frame 32 is provided with a mounting frame 33. The mounting frame 33 is provided with a drive motor 34. The output end of the drive motor 34 passes through the mounting frame 33 and is connected to a rotating rod 35 by a flange. The bottom of the rotating rod 35 passes through the connecting groove 21 and extends into the interior of the vessel body 1. The connecting groove 21 is provided with two sets of limiting rings 22. The limiting rings 22 are provided with lip seals 23. The lower end face of the rotating rod 35 is fixedly connected to a stirring paddle by screws 364.

[0024] The vessel body 1 is designed to store the raw materials that need to be reacted, while the drive motor 34 can drive the rotating rod 35 and the stirring paddle 36 to rotate, and make the rotating rod 35 and the stirring paddle 36 complete the stirring of the raw materials in the vessel body 1, ensuring the mixing of the raw materials.

[0025] The support frame 3, lifting component 31 and connecting frame 32 can adjust the position of the stirring paddle 36 in the reactor body 1, so that the stirring paddle 36 can be positioned at different heights in the reactor body 1 according to the different stages of the raw material reaction. This ensures that the stirring paddle 36 is always in the optimal stirring position according to the different stages of the reaction, thereby ensuring the quality of the adhesive after the mixing reaction.

[0026] Specifically, in the initial stage of the adhesive reaction, the lifting component 31 is driven to rotate downward through the connecting frame 32, so that the bottom of the stirring paddle 36 can be close to the bottom of the vessel body 1. During the rotation of the stirring paddle 36 in this position, it will directly act on the solid particles settled at the bottom of the vessel body 1 and break the solid agglomeration through high shear force, thereby avoiding the solid from depositing at the bottom of the vessel.

[0027] When the adhesive is in the middle of the reaction, as the solvent, resin and other liquid components are added, the liquid level gradually rises. The lifting component 31 can drive the stirring paddle 36 to slowly lift upward through the connecting frame 32, so that the stirring component is always in the "core mixing zone in the upper part of the liquid level", ensuring that the material forms a stable convection circulation, and further ensuring the quality of the adhesive raw materials after mixing and stirring.

[0028] In this embodiment, the lifting component 31 can adopt an existing hydraulic lifting structure or a cylinder lifting structure. The hydraulic lifting structure can adopt existing structures, such as piston hydraulic cylinders, MOD series hydraulic cylinders, etc.

[0029] It should be noted that existing technologies, such as hydraulic flow control synchronization technology or volumetric synchronization technology, can be used for the synchronization control of the two lifting components 31.

[0030] In this embodiment, the setting of the limiting ring body can limit the installation position of the lip seal 23, so that the lip seal 23 will not move with the movement of the rotating rod 35, and the setting of the lip seal 23 can seal the gap between the rotating rod 35 and the connecting groove.

[0031] It should be noted that the single lip seal 23 is suitable for adhesives with low sealing requirements; that is, the device itself is suitable for making adhesives with low sealing requirements.

[0032] like Figure 3As shown, the stirring paddle 36 includes a circular plate 361, an inner groove 362 opened on the top of the circular plate 361 for inserting the end of the stirring rod, and a first screw hole 363 on the circumferential direction of the base of the circular plate 361. The bottom of the rotating rod 35 is provided with a second screw hole opposite to the position of the first screw hole 363. The first screw hole 363 and the second screw hole are internally threaded with screws 364. A plurality of stirring blades 366 are provided on the circumferential direction of the circular plate 361, and a plurality of evenly distributed channels 365 are provided on the stirring blades 366.

[0033] The inner groove 362, the first screw hole 363, the second screw hole and the screw 364 make it easy for the staff to install and disassemble the agitator itself; while the channel 365 can generate a "jet effect" when the material passes through the channel 365 during the rotation of the agitator blade 366. This not only increases the strong shear force of the agitator blade 366 itself, but also improves the dispersibility of small molecule additives (such as curing agents).

[0034] like Figure 3 As shown, a limiting slider 4 is provided on the inner side of the upper end face of the support frame 3, and limiting grooves 41 that cooperate with the limiting slider 4 are provided at the front and rear ends of the support frame 3.

[0035] The limiting slider 4 and the limiting groove 41 work together to limit the range of motion of the connecting frame 32 and ensure the accuracy of the rotating rod 35 during its up and down movement.

[0036] like Figure 1 As shown, a suspension end 321 is provided on the connecting frame 32 and on both sides of the mounting frame, and a connecting block 24 is provided on the top of the top cover 2 and on both sides of the connecting groove 21. A hanging ring 25 that cooperates with the suspension end 321 is hinged on the connecting block 24.

[0037] The suspension end 321 cooperates with the scraper ring to lift the top cover 2 during the upward movement of the connecting frame 32 after the adhesive mixing reaction is completed, thus exposing the top of the vessel body 1. After the top cover 2 and the rotating rod 35 are separated from the vessel body 1, it is convenient for the staff to clean the adhesive inside the vessel body 1 and to clean the vessel body 1, the rotating rod 35 and the stirring paddle 36.

[0038] like Figure 5 As shown, a scraper 26 is provided at the bottom of the top cover 2 and below the connecting groove 21 via screw 364. The scraper 26 is cone-shaped on the side near the rotating rod 35.

[0039] The scraper 26 is designed to scrape off the adhesive adhering to the surface of the rotating rod 35, thereby avoiding the adhesive from affecting the lip seal 23.

[0040] In this embodiment, the scraper 26 can be made of materials such as carbon steel or ceramic.

[0041] As shown in the figure, an inner jacket 5 is provided inside the vessel body 1. A circulation output pipe communicating with the inner jacket 5 is provided on the upper side of one side of the vessel body 1, and a circulation input pipe 52 communicating with the inner jacket 5 is provided on the lower side of the other side of the vessel body 1.

[0042] The circulation output pipe 51, circulation input pipe and inner jacket 5 are set up to inject the medium into the inner jacket 5 and complete the heating of the vessel body 1. The circulation output pipe 51 and circulation input pipe 52 are used in conjunction with the external circulation pump and external medium heating element.

[0043] Working principle:

[0044] First, the workers pour the raw materials to be used into the vessel body 1, and simultaneously remove the top cover 2, placing it on top of the vessel body 1 and securing it with flanges. Next, the workers adjust the position of the stirring paddle 36 within the vessel body 1 using the support frame 3, lifting component 31, and connecting frame 32. This allows the stirring paddle 36 to be positioned at different heights within the vessel body 1 according to the different stages of the raw material reaction, ensuring the stirrer is always in the optimal stirring position for mixing the raw materials. After the adhesive is mixed, the lifting component 31 controls the connecting frame 32 and the rotating rod 35 to move downwards, and suspends the scraper ring on the suspension end 321. At the same time, the screws 364 on the flange are disassembled. Next, the lifting component 31 drives the connecting frame 32 to move upwards. During the upward movement of the connecting frame 32, the top cover 2 is lifted through the suspension end 321, exposing the top of the vessel body 1. After the top cover 2 and the rotating rod 35 are separated from the vessel body 1, the workers can clean the adhesive inside the vessel body 1 and clean the vessel body 1, the rotating rod 35 and the stirring paddle 36.

[0045] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.

[0046] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
