Description

Technical Field

[0001] This utility model relates to the field of water-based adhesive production equipment, and in particular to an auxiliary barrier-reinforcing water-based adhesive reaction vessel. Background Technology

[0002] Water-based adhesives bind solid particles such as pigments and fillers together, allowing ink to adhere to the surface of printing materials. They are an indispensable part of water-based ink systems. Their production primarily involves a reaction vessel, where raw materials are mixed and reacted to obtain water-based adhesives with specific functions. During the production process, the reaction environment within the reaction vessel has a crucial impact on the quality of the adhesive. However, existing reaction vessels for water-based adhesives still have many problems. For example, CN212549485U discloses a reaction vessel for water-based adhesive production, with a condenser cover connected to the top of the vessel. This only addresses the problems of poor cooling effect and easy leakage of condensate during collection, which are inconvenient for traditional water-based adhesives. However, in the production process of water-based adhesives, air entering with the materials easily carries oxygen and moisture. Oxygen can trigger an oxidation reaction in the adhesive components, while moisture can alter the adhesive's formulation ratio, affecting its performance and causing a rapid decrease in its adhesive strength. This results in ink failing to dry and cure for an extended period after printing, leading to problems such as ink sticking and smudging, thus impacting print quality and production efficiency. Simultaneously, the reaction of the adhesive within the reactor may generate gases, causing pressure increases and instability. This pressure instability can lead to gas backflow and mixing, altering the adhesive's viscosity and resulting in inconsistent ink flow during printing, affecting the ink's printability. Utility Model Content

[0003] (1) Technical problems solved

[0004] In view of the limitations of existing water-based adhesive reaction vessels, the purpose of this utility model is to provide an auxiliary barrier-enhanced water-based adhesive reaction vessel. By installing gas barrier devices at both the inlet and outlet of the reaction vessel, inert gas is introduced into the gas barrier chamber and filtered and purified sequentially. At the same time, a one-way valve is installed and a flow-limiting orifice plate is installed in the channel connected to the reaction vessel. This not only effectively filters and purifies the gas entering the reaction vessel, preventing oxygen, moisture and impurities in the outside air from entering the reaction vessel, thus providing a pure environment for the water-based adhesive reaction, but also ensures stable unidirectional gas flow, avoiding abnormal reaction and adhesive quality degradation caused by gas backflow, and effectively improving the stability and adaptability of ink printing.

[0005] (2) Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary barrier-enhancing water-based adhesive reactor, comprising a reactor body, an inlet at the top of the reactor body and an outlet at the bottom, both the inlet and outlet being fixedly connected to a gas isolation chamber via conveying pipes, the gas isolation chamber being divided into a filtration zone and a purification zone from top to bottom, the inner wall of the conveying pipe being provided with several flow-limiting plates in a "Z" shape, the flow-limiting plates being uniformly provided with flow-limiting holes, the flow-limiting holes being provided with wavy patterns, and both conveying pipes being gradually inclined downwards. The feed inlet is connected to the gas isolation chamber via a conveying pipe, and the discharge outlet is also connected to the gas isolation chamber via a conveying pipe. This means that before the material enters the reactor body for reaction, it first passes through the gas isolation chamber, where it is filtered and purified. Then, it enters the reactor body through the conveying pipe. At this point, the oxygen, moisture, and impurities in the material are basically absorbed, ensuring the performance of the water-based adhesive. The "Z"-shaped flow restrictor is set inside the conveying pipe to further slow down the gas flow rate and reduce the impact of the gas on the reactor body. Both ends of the flow restrictor are fixedly connected to the inner wall, and the corrugated surface of the flow restrictor guides the material flow and prevents the material from sticking together.

[0007] It should be noted that the "Z"-shaped flow restrictor is set at an angle, meaning that the "Z" is not completely horizontal. This is to promote the flow of materials while preventing gas backflow. The downward-sloping pipe is also designed to further prevent gas backflow and guide the flow of materials.

[0008] Similarly, the discharge port at the bottom of the reactor is connected to the gas isolation chamber through a pipe, which means that the material after reaction in the reactor will pass through the gas isolation chamber for gas isolation, further filtering out the gas in the material to obtain a purer water-based adhesive.

[0009] Preferably, a buffer tank is fixedly connected to the side of the delivery pipeline near the reactor body, and a first one-way valve is fixedly connected to the side of the delivery pipeline near the gas isolation chamber. The buffer tank, located inside the delivery pipeline near the reactor body, means that gas enters the buffer tank before entering the reactor body. The inner wall of the buffer tank is equipped with a vortex guide plate. The gas entering the buffer tank is guided by the vortex guide plate to form a vortex flow inside the tank, reducing the gas velocity and minimizing the impact on the reactor. Similarly, some of the gas generated inside the reactor body during the reaction first contacts the buffer tank when flowing towards the delivery pipeline, where it is reduced and slowed down. Thus, when gas generated inside the reactor body attempts to flow back into the delivery pipeline, the buffer tank first slows down the gas, and then the first one-way valve more effectively prevents the gas from entering the gas isolation chamber, further preventing backflow and its impact on the performance of the water-based adhesive.

[0010] Preferably, a gas filter is fixedly connected inside the filtration zone, and a gas purifier is fixedly connected inside the purification zone. The filtration zone and the purification zone are fixedly connected by a connecting pipe, and a second one-way valve is fixedly connected to the side of the delivery pipe near the filtration zone. Within the gas isolation chamber, the upper part is the filtration zone, and the lower part is the purification zone, connected by a delivery pipe. This means the filtration zone does not directly contact the purification zone; instead, gas is initially filtered by the gas filter in the filtration zone and then transported to the purification zone for further purification by the gas purifier. The second one-way valve, located near the filtration zone, ensures that gas flow is restricted to the purification zone, effectively preventing backflow. The gas filter and gas purifier can be connected to a control terminal, allowing them to be started and stopped. The gas filter and gas purifier utilize existing technology; their specific setup and connection methods are not detailed here.

[0011] Preferably, a stirring device is installed inside the reactor body, comprising a motor and a stirring paddle. The motor is fixed to the top of the inner wall of the reactor body, and its output shaft is fixedly connected to the stirring paddle, which is vertically positioned inside the reactor body. The top of the motor is fixedly connected to the inner wall of the top of the reactor, meaning the motor is fixed in the middle of the top part inside the reactor. Its output end is connected to the stirring paddle, which is vertically positioned in the middle of the reactor. When the motor is driven, its rotation drives the stirring paddle to rotate, thereby stirring the materials inside the reactor. The stirring paddle here is an anchor-type stirring paddle, with its blades closely attached to the inner wall of the reactor to prevent materials from sticking to the wall. The motor can be connected to a control terminal, which controls the motor's start and stop, thereby controlling the stirring and stopping of the stirring paddle. The specific connection method of the motor and the specific setting and connection of the anchor-type stirring paddle use conventional technology and therefore will not be described in detail.

[0012] Preferably, a heating jacket is fixedly connected to one side of the outer wall of the reactor body, and a cooling jacket is fixedly connected to the other side. The heating jacket and cooling jacket are symmetrically fixed on both sides of the reactor body, respectively heating and cooling the material. They can be used individually or simultaneously. A heating device is installed inside the heating jacket, and a cooling device is installed inside the cooling jacket. The heating device and cooling device are respectively connected to a control terminal, and their operation can be controlled through the control terminal. The specific settings and connection methods adopt conventional technology, so they will not be described in detail.

[0013] Preferably, each of the two gas isolation chambers has an air inlet at its top side. The air inlets are connected to a gas supply device via pipes, and the gas supply device contains inert gas. These air inlets are connected to the filtration zone. In other words, the air inlets are connected to the gas supply device via pipes. Note that a suction valve is installed at the connection point between the pipes and the gas supply device. Opening the suction valve draws gas into the gas supply device, and the inert gas in the gas supply device enters the pipes. Under the transport of the pipes, the gas enters the filtration zone through the air inlets, and then flows down through the filtration zone into the purification zone. At this point, the entire gas isolation chamber is filled with inert gas, meaning both the filtration zone and the purification zone are filled with inert gas.

[0014] To further clarify, inert gases here refer to gases that are chemically inert under normal chemical conditions and are unlikely to react chemically with other substances. This includes not only nitrogen (N2), but also, in the periodic table, helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). In this reactor apparatus, these inert gases are used to create a stable environment within the gas isolation chamber that is unlikely to react chemically with the adhesive.

[0015] To further explain, after the gas enters the gas isolation chamber, it first enters the filtration zone. The gas filter inside the filtration zone performs preliminary filtration. Gas filters are symmetrically installed on both inner walls of the filtration zone. The filter elements within these filters can filter particulate matter and dust particles from the gas, initially absorbing impurities. The pre-filtered gas is then transported to the purification zone through a delivery pipe. The filter element of the gas purifier in the purification zone has a higher filtration capacity than the gas filter element, further intercepting and removing minute impurities from the gas, further improving its purity. Simultaneously, molecular sieves are equipped in the gas purifier. These molecular sieves have a strong adsorption capacity for small molecules such as water molecules, further removing moisture from the gas. After entering the filtration zone, the gas comes into contact with inert gas, and it remains in contact with inert gas in the purification zone. The inert gas fills both the filtration and purification zones, effectively removing oxygen and creating an oxygen-free environment for the filtration and purification process. This ensures relatively stable parameters such as gas velocity and flow rate, improving the efficiency and quality of filtration and purification.

[0016] It should be noted that in this article, "water-based adhesive" and "water-based adhesive" refer to the same type of substance, but are used as different names.

[0017] Beneficial effects

[0018] (1) The feed inlet and discharge outlet of the reactor body are connected to the gas isolation chamber through the conveying pipeline. The gas isolation chamber has a filtration area and a purification area, and both are filled with inert gas. This can effectively prevent outside air from entering the reactor body. First, the presence of inert gas can prevent impurities such as oxygen and moisture in the air from reacting with the water-based adhesive, preventing the adhesive components from oxidizing and coming into contact with moisture, thus affecting the adhesive strength, water resistance and other properties of the adhesive, thereby ensuring the quality and performance of the adhesive.

[0019] (2) The inner walls of the two gradually downward-sloping conveying pipes are evenly provided with downward-sloping guide plates, and the surface of the guide plates is provided with a wavy pattern. The inner conveying pipes are equipped with a buffer tank and a first one-way valve. The buffer tank can cope with the fluctuation of the gas generation rate in the reactor. When the reaction is violent and a large amount of gas is generated, the buffer tank can contain the excess gas and protect the subsequent gas isolation device. The first one-way valve ensures that the gas can only flow from the main body of the reactor to the gas isolation chamber, preventing gas backflow and ensuring the stability of the reaction environment in the reactor. The inclined channel and flow limiting plate further ensure the unidirectional stable flow of gas, avoiding the problems of abnormal reaction and reduced adhesive quality caused by gas backflow.

Detailed Implementation

[0026] The following will refer to the appendix in the embodiments of this utility model. Figure 1 -Appendix Figure 5The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1: As Figure 1 As shown, the first specific embodiment of this utility model provides an auxiliary barrier-enhanced water-based adhesive reactor, including a reactor body 1. The reactor body 1 has an inlet 11 at its top and an outlet 12 at its bottom. Both the inlet 11 and outlet 12 are fixedly connected to a gas isolation chamber 3 via a conveying pipe 2. The gas isolation chamber 3 is divided into a filtration zone 31 and a purification zone 32 from top to bottom. The inner wall of the conveying pipe 2 is provided with several flow-limiting plates 20 arranged in a "Z" shape. Flow-limiting holes 200 are evenly arranged on the flow-limiting plates 20, and wavy patterns are provided between the flow-limiting holes 200. Both conveying pipes 2 gradually slope downwards. Firstly, due to the obstruction of the "Z"-shaped flow-limiting plates, the material needs to bypass these plates to continue moving forward. This lengthens the material's flow path and naturally reduces the flow velocity. This helps prevent the water-based adhesive material from experiencing violent impacts and splashes within the pipe, thereby reducing material loss and potential safety hazards. Secondly, when the pressure inside the reactor fluctuates or external factors cause pressure changes in the pipeline, backflow of materials may occur. The "Z"-shaped flow-limiting plate 20 structure resists this backflow, making it difficult for the material to flow backward and ensuring that the material is transported from the inlet or outlet to the gas isolation chamber in the predetermined direction. Furthermore, the flow-limiting holes 200 on the flow-limiting plate 20 allow for a more uniform distribution of material during passage, which improves processing efficiency and effectiveness during subsequent filtration and purification of the gas in the material within the gas isolation chamber.

[0028] Furthermore, when the material passes through the flow restrictor 20, the wavy pattern creates localized turbulence and eddies, promoting initial mixing of different parts of the material. This effectively prevents stratification or sedimentation of components in water-based adhesives containing multiple ingredients within the pipes. The design of both conveying pipes 2 gradually sloping downwards facilitates smooth material flow under gravity, especially for highly viscous water-based adhesives. The sloping pipes reduce material residue within the pipes, allowing for more complete delivery to the gas-isolated chamber and improving material conveying efficiency.

[0029] A buffer tank 4 is fixedly connected to the inside of the delivery pipeline 2, near the side of the reactor body 1, and a first one-way valve 5 is fixedly connected to the inside of the delivery pipeline 2, near the gas isolation chamber 3. During the reaction of the water-based adhesive, gas may be generated inside the reactor body, and the generation rate of this gas is often unstable. The buffer tank 4, located near the reactor body 1, can act as a temporary storage space to accommodate excess gas when a large amount is generated, preventing a sudden increase in gas flow from causing excessive impact on the subsequent gas isolation chamber and the entire delivery pipeline system. Furthermore, when the pressure inside the reactor increases, gas enters the buffer tank 4, and the pressure inside the buffer tank 4 also increases accordingly. However, due to its certain volume, the pressure increase will be less than if there were no buffer tank. Conversely, when the pressure inside the reactor decreases, the gas in the buffer tank can replenish the reactor, maintaining a certain pressure and preventing excessively low pressure from adversely affecting the reaction. This helps to maintain a relatively stable pressure inside the reactor, creating a favorable environment for the reaction of the water-based adhesive.

[0030] The first one-way valve 5 is located on the side close to the gas isolation chamber 3. Its core function is to ensure that the gas can only flow from the main body 1 of the reactor to the gas isolation chamber 3 and cannot flow in the opposite direction, preventing the gas from flowing back into the reactor, avoiding interference with the reaction inside the reactor, and ensuring the normal progress of the reaction.

[0031] A gas filter 310 is fixedly connected inside the filtration zone 31, and a gas purifier 320 is fixedly connected inside the purification zone 32. The filtration zone 31 and the purification zone 32 are fixedly connected by a connecting pipe 33. Both the filtration zone 31 and the purification zone 32 are filled with inert gas. A second one-way valve 34 is fixedly connected to the side of the delivery pipe 33 near the filtration zone 31. The gas first passes through the gas filter 310 in the filtration zone 31, which removes solid particulate impurities such as dust and small metal fragments. These impurities may adversely affect the subsequent reaction process. Then, the gas enters the gas purifier 320 in the purification zone 32 to further remove any potentially harmful gaseous components, such as moisture, oxygen, or other gases that may react with the water-based adhesive. This stepwise filtration and purification method can more effectively ensure the quality of the gas entering the reactor, improving the quality and stability of the adhesive product. A pure gas environment is crucial for the reaction of water-based adhesives. By using gas filters and purifiers, the composition of the gas entering the reactor can be precisely controlled, eliminating factors that may interfere with the reaction and ensuring that the reaction proceeds as expected. This allows for better control of the adhesive's performance, such as bond strength, drying speed, and water resistance.

[0032] Secondly, filling the filtration zone 31 and purification zone 32 with inert gas effectively prevents oxygen from entering. In other words, the inert gas creates an oxygen-free protective environment, ensuring that no oxygen is introduced during the filtration and purification process, or when the gas subsequently enters the reactor, thus protecting the quality of the adhesive. This makes the gas properties more stable during the filtration and purification process, which is beneficial for improving filtration and purification efficiency, and also provides a reliable working environment for the entire gas treatment system.

[0033] The second one-way valve 34 is positioned near the filtration zone 31, ensuring that gas can only flow from the filtration zone 31 to the purification zone 32. This guarantees that the gas passes through the gas filter 310 and the gas purifier 320 in a predetermined direction, preventing the purified gas from flowing back into the filtration zone 31. This helps maintain the order and effectiveness of gas purification, improving the overall efficiency and reliability of the gas isolation chamber 3. The presence of the second one-way valve 34 allows the filtration zone 31 and the purification zone 32 to function independently while ensuring their coordinated operation. It makes the gas flow between the two zones more orderly, facilitating separate monitoring and management of the filtration and purification processes.

[0034] A stirring device 6 is installed inside the reactor body 1. The stirring device 6 includes a motor 61 and a stirring paddle 62. The motor 61 is fixed to the top of the inner wall of the reactor body 1, and its output shaft is fixedly connected to the stirring paddle 62, which is vertically arranged inside the reactor body 1. In the production process of water-based adhesives, multiple components are usually included. The presence of the stirring device 6 allows these different components to be fully mixed within the reactor body 1. For the synthesis reaction of adhesives, the reactants need to be in full contact to ensure uniform reaction. The motor 61 drives the stirring paddle 62 to rotate, and the stirring paddle 62 generates shear force and circulation effect on the materials, allowing the various components to be evenly dispersed throughout the reaction system. This ensures that the polymerization reaction occurs uniformly throughout the reactor, preventing local over-reaction or under-reaction, thereby improving the consistency of product quality.

[0035] A heating jacket 7 is fixedly connected to one side of the outer wall of the reactor body 1, and a cooling jacket 8 is fixedly connected to the other side. In the production process of water-based adhesives, different reaction stages often require different temperature conditions. The heating jacket 7 and cooling jacket 8 allow for flexible increases or decreases in the reactor temperature according to the specific needs of the reaction. That is, in the initiation stage of adhesive synthesis, the heating jacket may be used to provide heat to initiate the polymerization reaction and achieve a suitable reaction rate; while in the later stages of the reaction, when the reaction is highly exothermic, the cooling jacket can remove excess heat, preventing runaway reactions and ensuring the reaction proceeds within the optimal temperature range, thereby effectively controlling the reaction process and improving product quality. Secondly, this double-sided jacket structure can respond quickly to temperature changes. When a temperature increase is needed, the heating jacket 7 works rapidly; when a temperature decrease is needed, the cooling jacket 8 immediately takes effect. Through the coordinated control of the heating jacket 7 and cooling jacket 8, more precise temperature control within the reactor can be achieved.

[0036] Each of the two gas-isolated chambers 3 has an air inlet 30 on one side, which is connected to a gas supply device containing inert gas via a pipe. Water-based adhesive components are sensitive to oxygen, which can trigger an oxidation reaction, leading to a decline in adhesive performance. Supplying inert gas to the gas-isolated chambers 3 through the air inlets 30 effectively removes air from the chambers, creating an oxygen-free environment and preventing oxygen from contacting the adhesive components, thus ensuring the stability of the adhesive's performance and quality. Besides oxygen, air also contains moisture, carbon dioxide, and other impurities. These gases can also affect the drying speed and final bonding performance. The supply of inert gas displaces these impurities from the gas-isolated chambers 3, providing a pure gaseous environment for the adhesive's reaction.

[0037] Working principle: In operation, the control terminal first controls the inert gas to enter the filter zone 31 of the gas isolation chamber 3 through the inlet 30 via the pipeline, and then enters the purification zone 32 through the connecting pipe 33. The inert gas then fills the entire gas isolation chamber 3. The material enters the reactor body 1 from the feed inlet 11. The material first contacts the gas isolation chamber 3, where it is filtered by the gas filter 310 and then purified by the gas purifier 320. The purified material enters the conveying pipeline 2 and flows slowly downward under the guidance of the flow limiting plate 20 and the flow limiting orifice 200. Before flowing into the reactor body 1, it contacts the buffer tank 4, which further reduces the pressure on the material. After the material enters the reactor body 1, the motor 61 starts and rotates, which drives the stirring paddle 62 to rotate, fully stirring the material in the reactor body 1 to cause a reaction. The fully stirred material flows out from the outlet 12. During the outflow process, it first contacts the buffer tank 4 and then enters the conveying pipe 2 under the buffer of the buffer tank 4. The flow limiting plate 20 and flow limiting hole 200 inside the conveying pipe 2 buffer and guide the material, and then convey the material to the gas isolation chamber 3. In the gas isolation chamber 3, the gas filter 310 filters the material, and the gas purifier 320 further purifies the material, finally obtaining pure reacted material.

[0038] During the reaction process in the reactor body 1, when the reaction requires heating, the control terminal controls the heating jacket 7 to provide heat to the reactor body 1, so that the material in the reactor reaches the temperature required for the reaction and accelerates the reaction process. When the reaction enters the exothermic stage or the temperature is too high and needs to be cooled, the control terminal controls the cooling jacket 8 to remove the heat by introducing a cooling medium, preventing the reaction from getting out of control, ensuring that the reaction takes place within a suitable temperature range, thereby optimizing the reaction rate, improving product quality, and ensuring the safety of the reactor.
