Description

Technical Field

[0001] This utility model relates to the field of water-based ink cleaning agent production technology, and in particular to a reaction vessel for producing water-based ink cleaning agents. Background Technology

[0002] Water-based ink cleaners are environmentally friendly cleaning agents made primarily of water, supplemented with surfactants, co-solvents, chelating agents, and other additives. They are produced through processes such as mixing, dispersion, and low-temperature heating (typically 50-80℃) and are widely used for cleaning ink residues in printing equipment. The core of their production lies in achieving uniform mixing and stable dispersion of the components through a reaction vessel, requiring strict control of temperature and mixing efficiency.

[0003] Traditional reactors for producing water-based ink cleaning agents typically use a single, integral heating jacket on the side wall of the reactor body to achieve heating and continuous low-temperature heating (0-40℃). However, this design has significant drawbacks: First, the heating jacket is large and has a fixed coverage area, resulting in significant axial (upper and lower) and radial (inner and outer) temperature differences within the reactor body. This can easily cause localized additive failure due to high temperatures or insufficient dissolution at low temperatures. Second, a single heating jacket can only control the temperature through overall power adjustment, and cannot accurately compensate for the differences in heat dissipation in different areas of the reactor body (such as faster heat dissipation at the bottom due to contact with the support, and greater heat dissipation at the top due to contact with the air), resulting in low temperature control accuracy. Third, the integral heating jacket has low heating efficiency, requiring long-term operation to bring the liquid inside the reactor to the target temperature, and also consumes a lot of energy. To solve the above problems, this utility model proposes a reactor for producing water-based ink cleaning agents. Utility Model Content

[0004] The main objective of this invention is to provide a reaction vessel for the production of water-based ink cleaning agents, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reaction vessel for producing water-based ink cleaning agent includes a vessel lid and a vessel body. The vessel lid is connected to multiple first inlet pipes and one second inlet pipe. A motor is fixedly connected to the upper end of the vessel lid, and a stirring shaft is fixedly connected to the output shaft of the motor. Multiple stirring plates are fixedly connected to the side wall of the stirring shaft. A discharge pipe is connected to the lower end of the vessel body. A heating mechanism for heating the vessel body is provided on the side wall of the vessel body. The heating mechanism includes multiple heating sleeves fixedly connected to the side wall of the vessel body, multiple heating tubes inside the heating sleeves, multiple temperature sensors on the heating sleeves, a mounting plate on the side wall of the heating sleeves, and a temperature controller mounted on the side wall of the mounting plate. A flow distribution mechanism for dispersing liquid is provided inside the vessel lid.

[0007] Preferably, the diversion mechanism includes multiple mounting blocks fixedly connected to the top of the vessel lid, and a diversion ring pipe is installed on the multiple mounting blocks. The lower end of the diversion ring pipe has multiple water leakage holes, and the lower end of the first liquid inlet pipe is connected to the diversion ring pipe.

[0008] Preferably, the upper end of the first liquid inlet pipe is connected to a feed hopper, and the feed hopper is provided with a sealing cover.

[0009] Preferably, the sealing cover is threadedly connected to the feed hopper, and a handle is fixedly connected to the upper end of the sealing cover.

[0010] Preferably, a limiting ring is installed at the upper end of the discharge pipe by multiple mounting rods, and multiple ball bearings are provided at the bottom of the limiting ring.

[0011] Preferably, the lower end of the limiting ring is provided with a drain hole, and the plurality of mounting rods are arranged at equal intervals.

[0012] Preferably, the sidewall of the stirring plate has multiple through holes, and the multiple through holes are arranged at equal intervals.

[0013] Preferably, the heating jacket has an insulating sleeve on its side wall, and the plurality of drainage holes are arranged at equal intervals.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This device is equipped with a heating mechanism, with multiple heating jackets for zoned heating. With the help of independent temperature controllers and temperature sensors, the temperature of different areas can be adjusted in real time to avoid the failure of the additives due to local high temperature or insufficient dissolution at low temperature, thus ensuring the stability of the cleaning agent.

[0016] 2. This device is equipped with a diversion mechanism. The diversion ring pipe disperses and drips the additives through multiple water leakage holes. Combined with the stirring of the stirring plate, the dispersion time of the additives is greatly shortened, avoiding the problem of excessively high local concentrations.

[0017] 3. This device is equipped with a limiting ring and ball bearings to prevent the lower end of the stirring shaft from being suspended in the air, ensuring a stable stirring flow field and improving mixing consistency;

[0018] 4. This device is equipped with an insulation jacket, which reduces heat loss from the heating jacket. Zoned heating can compensate for differences in heat dissipation, making it more energy-efficient than the traditional integral heating jacket. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-5 As shown, a reaction vessel for producing water-based ink cleaning agent includes a lid 1 and a body 2 (connected by multiple bolts and nuts, not shown in the figure). The lid 1 is connected to multiple first liquid inlet pipes 6 and a second liquid inlet pipe 14 (for plasma water feeding). A motor 15 is fixedly connected to the upper end of the lid 1. A stirring shaft 3 is fixedly connected to the output shaft of the motor 15. Multiple stirring plates 5 are fixedly connected to the side wall of the stirring shaft 3. A discharge pipe 4 is connected to the lower end of the body 2.

[0027] The side wall of the vessel body 2 is provided with a heating mechanism for heating the vessel body 2. The heating mechanism includes multiple heating sleeves 9 fixedly connected to the side wall of the vessel body 2. Multiple heating tubes 10 are provided inside the heating sleeves 9. Multiple temperature sensors 7 are provided on the heating sleeves 9. A mounting plate 11 is provided on the side wall of the heating sleeves 9. A temperature controller 12 is installed on the side wall of the mounting plate 11. The probes of the temperature sensors 7 are located inside the heating sleeves 9. The heating sleeves 9 are filled with heating oil. The multiple heating sleeves 9 are evenly distributed along the axial direction of the vessel body 2 (e.g., ...). Figure 2 It can achieve "zoned heating". With its respective temperature sensor 7 and temperature controller 12, it can adjust the temperature of different areas in real time (e.g., the bottom heating jacket 9 has a higher power than the top to compensate for the heat dissipation difference), so that the axial temperature difference of the vessel body 2 is controlled within ±1-2℃.

[0028] Heating tubes 10 are evenly distributed inside heating jacket 9. With the heat conduction of heating oil, the radial temperature of the area covered by a single heating jacket 9 is uniform. The temperature controller 12 and the temperature sensor 7 form a closed-loop control, which can accurately maintain the target temperature (fluctuation ≤ ±1℃) and prevent the additives from failing due to overheating.

[0029] The vessel lid 1 is provided with a flow-dividing mechanism for dispersing liquid. The flow-dividing mechanism includes multiple mounting blocks fixedly connected to the top of the vessel lid 1. A flow-dividing ring pipe 16 is installed on the multiple mounting blocks. Multiple water leakage holes 17 are opened at the lower end of the flow-dividing ring pipe 16. The lower end of the first liquid inlet pipe 6 is connected to the flow-dividing ring pipe 16.

[0030] In this utility model, the upper end of the first liquid inlet pipe 6 is connected to a feed hopper 13, and the feed hopper 13 is provided with a sealing cover, which can reduce liquid spillage when various additives are poured in from the first liquid inlet pipe 6. Valves are provided on the first liquid inlet pipe 6, the second liquid inlet pipe 14, and the discharge pipe 4 (as shown in the figure).

[0031] In this utility model, the sealing cover is threadedly connected to the feed hopper 13, and a handle is fixedly connected to the upper end of the sealing cover. The threaded connection ensures that the sealing cover and the feed hopper 13 fit tightly together, preventing liquid from splashing or external dust from entering during the stirring process. The handle design facilitates the quick disassembly and assembly of the sealing cover, improving the ease of operation.

[0032] In this utility model, a limiting ring 18 is installed on the upper end of the discharge pipe 4 through multiple mounting rods 19. Multiple balls 20 are provided at the bottom of the inner side of the limiting ring 18. The limiting ring 18 cooperates with the lower end of the stirring shaft 3 and forms a double support structure with the motor 15 to limit the radial swing of the stirring shaft 3. The balls 20 reduce the frictional resistance between the stirring shaft 3 and the limiting ring 18, ensuring the stability of the stirring shaft 3 when rotating at high speed (300-500 r / min) and avoiding the collision between the stirring plate 5 and the inner wall of the vessel 2 caused by the shaking of the shaft.

[0033] In this utility model, a drain hole is provided at the lower end of the limiting ring 18, and multiple mounting rods 19 are arranged at equal intervals. The drain hole prevents liquid from accumulating inside the limiting ring 18, and the equally spaced mounting rods 19 ensure that the limiting ring 18 is subjected to uniform force, thereby improving the structural stability.

[0034] In this invention, the side wall of the stirring plate 5 is provided with multiple through holes, which are equally spaced to defoam. The through holes allow some liquid to flow from one side of the plate to the other during stirring, forming local turbulence and enhancing liquid disturbance (especially effective for dispersing high-viscosity additives). At the same time, the through holes can break up the bubbles generated by stirring (surfactants are prone to foaming), preventing residual bubbles from affecting the filling and stability of the cleaning agent.

[0035] In this invention, the heating jacket 9 has an insulation jacket 8 on its side wall and multiple drainage holes 17 are set at equal intervals. The insulation jacket 8 (such as aluminum silicate cotton material) can reduce the heat loss of the heating jacket 9 and reduce energy consumption (15%-20% more energy saving than traditional design); the equally spaced drainage holes 17 ensure that the additive drips evenly and avoids local accumulation.

[0036] When in use, first add a certain amount of deionized water into the vessel 2 through the second liquid inlet pipe 14, and start the motor 15 to drive the stirring shaft 3 to rotate (the stirring plate 5 rotates synchronously);

[0037] Heating process: According to process requirements (e.g., 50℃), the target temperature of each heating jacket 9 is set by the temperature controller 12. The temperature sensor 7 monitors the temperature of the corresponding heating jacket 9 in real time. If the temperature of a certain area is lower than the set value (e.g., the bottom heating jacket 9 cools down due to rapid heat dissipation), the temperature controller 12 controls the heating tube 10 in that area to increase the power. If the temperature of a certain area is too high (e.g., the top heating jacket 9 cools down slowly), the power is reduced. The temperature of multiple heating jackets 9 is controlled independently in each zone to ensure that the overall temperature difference of the liquid in the vessel body 2 is ≤±1℃, providing a stable environment for the dissolution of additives.

[0038] Additive mixing process: Surfactants, corrosion inhibitors and other additives are added to the feed hopper 13 through different first liquid inlet pipes 6. The additives flow into the distribution ring pipe 16 through the first liquid inlet pipe 6, and then drip evenly onto the liquid surface in the reactor through multiple water leakage holes 17. When the stirring plate 5 rotates, the turbulence formed by the through holes quickly entrains the dispersed additives into the liquid, avoiding excessively high local concentrations. At the same time, the vertical distribution of the stirring plate 5 ensures that the liquid at different heights in the reactor 2 can be fully mixed, so that the additives are evenly dispersed in the deionized water.

[0039] After mixing is complete, turn off motor 15 and heating jacket 9, open valve of discharge pipe 4, and discharge cleaning agent through discharge pipe 4.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
