Description

Technical Field

[0001] This utility model relates to a dual-cavity emulsification reaction structure for the production of water-based adhesives. Background Technology

[0002] Traditional water-based adhesive production takes place in a single chamber. High-speed shear emulsifiers subject materials that are not yet fully mixed to strong shearing. This "brutal" working condition can easily lead to local overheating or excessive shearing, which can damage the stability of the emulsion and cause problems such as wide particle size distribution, easy stratification, and large performance fluctuations in the final product. It cannot simultaneously meet the two different process requirements of "gentle mixing" and "strong shearing".

[0003] Therefore, a dual-cavity emulsification reaction structure for the production of water-based adhesives is proposed to address the above issues. Utility Model Content

[0004] The purpose of this invention is to overcome the existing defects by providing a dual-cavity emulsification reaction structure for the production of water-based adhesives, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-cavity emulsification reaction structure for water-based adhesive production, comprising: frame; The pre-emulsification module, integrated on the frame, includes a pre-emulsification tank, a first motor driving the stirring shaft, and a feed inlet located at the top of the pre-emulsification tank; The fine emulsification module, integrated on the frame, includes a fine emulsification tank, a second motor driving the homogenizer head, and a discharge port located at the bottom of the fine emulsification tank; The connecting module includes a connecting pipe and a delivery pump. The two ends of the connecting pipe are respectively connected to the pre-emulsification tank and the fine emulsification tank, and the delivery pump is installed on the connecting pipe.

[0006] Preferably, the frame is integrally formed from the base and the guardrail, and the base has a hollow design.

[0007] Preferably, the feed inlet is connected to a conical hopper, and the opening of the conical hopper is screwed with an openable cover.

[0008] Preferably, the fine emulsification module further includes a vacuum degassing tube located at the top of the fine emulsification tank, and the vacuum degassing tube is connected to a vacuum pump.

[0009] Preferably, a check valve is provided on the discharge port.

[0010] Preferably, both the pre-emulsification tank and the fine emulsification tank are made of stainless steel.

[0011] Preferably, the guardrail is integrally formed by interlacing and welding strip-shaped bars.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the dual-cavity emulsification reaction structure used in the production of water-based adhesives separates the two physical processes of "mild premixing" and "high-intensity shear emulsification" in space, avoiding the damage that high-intensity shearing in a single container may cause to the material system that has not yet been mixed evenly, making the emulsification process more mild and controllable, and the final product of water-based adhesive has a narrower emulsion particle size distribution and higher stability, and the consistency of product quality is strongly guaranteed.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-4 As shown, the dual-chamber emulsification reaction structure for water-based adhesive production includes: frame 1.

[0017] The pre-emulsification module 2, integrated on the frame 1, includes a pre-emulsification tank 21, a first motor 22 driving the stirring shaft 24, and a feed inlet 23 located on the top of the pre-emulsification tank 21. The first motor 22 is installed on the top of the pre-emulsification tank 21, the stirring shaft 24 is located inside the pre-emulsification tank 21, and the feed inlet 23 is connected to a conical hopper 231. The opening of the conical hopper 231 is threaded with an openable cover 232. The conical hopper 231 facilitates the pouring of materials and reduces flying and spilling. The threaded cover 232 provides a reliable seal to prevent dust from escaping or foreign objects from falling in during the stirring process, thus maintaining a clean production environment.

[0018] The fine emulsification module 3, integrated on the frame 1, includes a fine emulsification tank 31, a second motor 32 driving the homogenizer head 36, and a discharge port 34 located at the bottom of the fine emulsification tank 31. The homogenizer head 36 is located inside the fine emulsification tank 31, the second motor 32 is installed on the top of the fine emulsification tank 31, and a check valve 35 is provided on the discharge port 34. The check valve 35 can precisely control the flow rate and opening and closing of the discharge, ensuring the smoothness and controllability of the production process.

[0019] The connecting module 4 includes a connecting pipe 41 and a delivery pump 42. The two ends of the connecting pipe 41 are connected to the pre-emulsification tank 21 and the fine emulsification tank 31, respectively, and the delivery pump 42 is installed on the connecting pipe 41.

[0020] Specifically, the frame 1 is integrally formed from the base 11 and the guardrail 12. The base 11 has a hollow design, and the guardrail 12 is integrally formed by interlacing and welding strips. The base 11 is used to support the pre-emulsification module 2 and the fine emulsification module 3, and the guardrail 12 can be used to isolate and protect the pre-emulsification tank 21 and the fine emulsification tank 31. The guardrail 12 forms a physical isolation, effectively protecting the operator from injury from high-speed moving parts, and also preventing external objects from accidentally hitting the tank. In addition, the hollow design of the base 11 provides valuable operation, maintenance and visual observation space for the bottom pipes, discharge port 34 and check valve 35, which facilitates the connection of hoses, leakage inspection and maintenance.

[0021] Specifically, the fine emulsification module 3 also includes a vacuum degassing tube 33 located at the top of the fine emulsification tank 31. The vacuum degassing tube 33 is connected to a vacuum pump and performs vacuum degassing directly during or after emulsification. This eliminates the need to transfer materials to a dedicated degassing device, greatly improves efficiency, reduces the risk of contamination, and effectively eliminates the negative impact of bubbles on the density and appearance of the product.

[0022] Specifically, both the pre-emulsification tank 21 and the fine emulsification tank 31 are made of stainless steel. Using stainless steel to manufacture the tank body and pipes can effectively prevent rust and corrosion, and is easy to clean and disinfect, meeting the strict requirements of the chemical industry for equipment materials and ensuring product quality and equipment life.

[0023] In summary, the frame 1 integrates a pre-emulsification module 2 and a fine emulsification module 3, which are connected by a connecting module 4. By rotating the cover 232 using its internal thread, the conical hopper 231 is opened, allowing water, emulsion, and other materials to be added to the pre-emulsification tank 21 through the feed inlet 23. Starting the first motor 22 drives the stirring shaft 24 at its output end to rotate inside the pre-emulsification tank 21 for initial mixing. Then, the delivery pump 42 is started, conveying the pre-treated material from the pre-emulsification tank 21 into the fine emulsification tank 31 through the connecting pipe 41. Next, the second motor 32 is started, driving the homogenizer head 36 to rotate inside the fine emulsification tank 31 for fine emulsification. The vacuum degassing pipe 33 at the top of the fine emulsification tank 31 can be connected to a vacuum pump to create a pressure difference and eliminate air bubbles on the internal liquid surface. Vacuum degassing is a separate step after fine emulsification. That is: After high-shear emulsification is completed in the fine emulsification tank 31, the second motor 32 is stopped.

[0024] Then start the vacuum pump to perform degassing under static or low-speed stirring.

[0025] After degassing is complete, finally open the check valve 35 on the discharge port 34 at the bottom of the fine emulsification tank 31, and then open the discharge port 34 to discharge the product.

[0026] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
