Description

Technical Field

[0001] This utility model relates to the field of concentration technology, specifically to a detergent concentration device. Background Technology

[0002] In the production process of liquid detergents, concentration is a crucial step. Its purpose is to remove a large amount of water from the solution through heating and evaporation to obtain a product with the required concentration of active ingredients. This process directly affects the quality of the final product, production costs, and efficiency.

[0003] Currently, the concentration devices commonly used in the industry are mostly large-scale batch evaporation kettles. Their working principle involves placing a large amount of detergent solution inside the kettle and heating it as a whole through a jacket or coil to promote water evaporation. However, this traditional equipment has many inherent drawbacks: First, due to the large depth of solution settling, the heating is extremely uneven. Liquid near the heat source is prone to overheating, causing coking and deterioration, while the evaporation efficiency in the central area is very low, affecting the uniformity and stability of product quality. Second, the entire heating process is energy-intensive, has a long cycle, and is intermittent, making continuous production impossible and severely restricting production efficiency. Finally, such equipment is bulky, occupies a large area, and is very inconvenient to clean and maintain. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a detergent concentration device, which achieves efficient and uniform concentration of detergent solution by combining multi-layer diversion and mechanical pushing.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detergent concentration device, including a mounting frame, on the top of which a filter device, a concentration mechanism, and a collection box are arranged sequentially from top to bottom. The concentration mechanism includes a concentration chamber, a heating base, a pushing mechanism, and a conveying assembly. The outlet of the filter device is connected to a diversion pipe, which penetrates the upper part of the concentration chamber.

[0008] The heating base is fixedly installed inside the concentration tank and arranged at an angle. Multiple parallel heating baffles are provided on its top, forming a narrow concentration channel between adjacent heating baffles. Heating wires are embedded inside the heating baffles for heating and evaporating the liquid flowing through the concentration channel.

[0009] The pushing mechanism includes a pushing motor. The output end of the pushing motor is connected to two pushing main shafts via a gearbox. Multiple sets of guide rings are fixedly installed on the outer periphery of each pushing main shaft. Each set of guide rings extends into the corresponding concentration channel and maintains a small gap with the inner wall of the channel.

[0010] Furthermore, the guide ring has a double-layered disc structure, with multiple guide vanes radially distributed along the circumference embedded between the two discs. When the guide ring rotates, the guide vanes generate a forward pushing force on the liquid, while simultaneously scraping the liquid evenly onto the surface of the heating baffle to form a thin liquid film, greatly increasing the heating area.

[0011] Furthermore, the upper part of the diversion pipe is provided with a plurality of evenly arranged diversion holes, and the position of each diversion hole corresponds to the inlet of the corresponding concentration channel, ensuring that the liquid to be concentrated can be evenly distributed to each concentration channel to achieve parallel processing.

[0012] Furthermore, the conveying assembly includes a conveying main shaft with helical conveying blades disposed on its exterior. The conveying main shaft is located at the lower end of the heating base, which is inclined, and is used to receive the concentrated liquid flowing out from the end of the concentration channel and push it to the drain port.

[0013] Furthermore, the conveying main shaft and the pushing main shaft are connected by a sprocket transmission mechanism. This design requires only one pushing motor to drive both the pushing mechanism and the conveying assembly simultaneously, simplifying the structure and reducing cost and energy consumption.

[0014] Furthermore, the heating seat is provided with a downwardly recessed arc-shaped groove corresponding to the position of the conveying assembly, and a drain port is provided at the end of the arc-shaped groove. The arc-shaped groove cooperates with the conveying blades to effectively collect and guide viscous concentrate.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the detergent concentration device provided by this utility model has the following significant advantages:

[0017] Firstly, this invention achieves parallel processing of the liquid by using a diversion pipe and multiple parallel concentration channels. The total evaporation area is distributed across multiple narrow channels, increasing the overall heat exchange area several times over and significantly improving the water evaporation rate per unit time. The concentration efficiency is significantly higher than that of traditional single-unit evaporation kettles. Simultaneously, the heating baffles embed heating wires to directly heat the thin liquid film, resulting in a short heat transfer path, low thermal resistance, and efficient utilization of heat energy. This avoids the significant heat loss associated with heating a large kettle body as a whole, effectively reducing energy consumption.

[0018] Secondly, the combination of the guide ring and guide blades in the pushing mechanism not only provides the driving force for forward pushing during rotation, but also continuously scrapes the liquid onto the surface of the heating baffle, forming a uniform and constantly renewed thin liquid film. This dynamic film-forming mechanism effectively avoids liquid stagnation and localized overheating on the heating wall, fundamentally preventing the active ingredients of the detergent from coking, carbonizing, or deteriorating due to prolonged high temperatures, ensuring a high degree of uniformity and stability in the color, activity, and quality of the final concentrated product.

[0019] Finally, the entire device adopts a top-down modular layout, integrating filtration, concentration, and collection functions into one unit, resulting in high space utilization and a small footprint. The power system uses a single motor to simultaneously drive both the pushing and conveying mechanisms via sprocket transmission, simplifying the transmission structure, reducing manufacturing costs and failure rates, and making operation more reliable.

[0029] The following will refer to the appendix in the example of this utility model. Figures 1-8 The 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.

[0030] like Figure 1-8 As shown, this utility model provides a detergent concentration device, the main body of which is a rigid mounting frame 1 welded from structural steel. A filter device 2 is installed on the top platform of the mounting frame 1. In this embodiment, a basket filter or a bag filter can be selected. Its inlet is connected to an external feeding system via a pipe, used to pre-treat the input detergent concentrate, filtering out any particulate impurities that may be present, and preventing blockage of the subsequent concentration channel.

[0031] The filtered clean liquid flows under pressure into a diversion pipe 35 connected to the outlet of the filter device 2. This diversion pipe 35 is horizontally positioned within the upper chamber of the concentration tank 31. A series of uniformly sized and equally spaced diversion holes 351 are machined along the axial direction on the top wall of the diversion pipe 35. The number of diversion holes 351 strictly corresponds to the number of concentration channels 322 provided on the heating base 32 below.

[0032] The outer shell of the concentration mechanism 3 is a sealed concentration chamber 31, and a heating base 32 is fixedly installed inside the chamber. The heating base 32 is made of cast aluminum alloy and is fixedly installed at an angle preferably 5-10°. This inclined design provides natural power for the liquid to flow downward under the combined action of its own gravity and subsequent pushing force.

[0033] The top surface of the heating base 32 is provided with multiple parallel heating baffles 321. Adjacent heating baffles 321 form a narrow, rectangular concentrating channel 322. Each heating baffle 321 is pre-embedded with an electric heating wire 323. The electric heating wire 323 is connected to an external temperature control system via a centralized terminal block, enabling temperature control of each concentrating channel 322 to accommodate detergents of different viscosities and concentration requirements.

[0034] The pushing mechanism 33 is responsible for driving the liquid to move smoothly and evenly in the concentration channel 322. The pushing motor 331 drives one pushing main shaft to rotate through a reducer and is driven by the other pushing main shaft through a sprocket structure. The two pushing main shafts 332 are arranged in the upper region of the concentration channel 322, and multiple sets of guide rings 333 are fixed on each main shaft 332 by a key connection. The position of each set of guide rings 333 can extend into a corresponding concentration channel 322 without interference, and maintain a very small and uniform operating gap with the inner wall of the channel and the side wall of the heating baffle 321.

[0035] The guide ring 333 adopts a special double-layer disk structure, with the two disks connected and fixed by multiple guide blades 3331 evenly distributed circumferentially and arranged radially. When the push shaft 332 drives the guide ring 333 to rotate, these guide blades 3331 mainly play three roles: First, they generate a forward and continuous pushing force on the liquid dripping from the diversion hole 351, overcoming the viscosity resistance increased by the concentration of the liquid; second, they continuously scrape and coat the liquid onto the wide sidewall of the heating baffle 321, forming an extremely thin and constantly renewed liquid film, which greatly increases the heated surface area of ​​the liquid, thereby significantly improving the efficiency of water evaporation; third, their rotational motion produces a slight agitation on the liquid, which helps the steam bubbles escape and prevents "boiling over" or coking.

[0036] The liquid undergoes heating and pushing in the concentration channel 322, where water is continuously evaporated, the concentration gradually increases, and finally flows out from the inclined lower end of the heating seat 32 as a viscous concentrate. In order to effectively collect and transport these high-viscosity liquids, this invention provides a downwardly recessed arc-shaped groove 324 at the lower end of the heating seat 32, which matches the conveying component 34.

[0037] The conveying assembly 34 includes a conveying main shaft 341 and helical conveying blades 342 fixed thereon. The conveying main shaft 341 is linked to one of the pushing main shafts 332 via a sprocket drive mechanism. The entire concentration unit's mechanical power is provided by a single pushing motor 331, achieving a unified power source, greatly simplifying the electrical control system, and reducing manufacturing costs and operating energy consumption. The helical conveying blades 342 rotate slowly within the arc-shaped groove 324, their function being to smoothly and continuously push the concentrated liquid collected thereto towards the drain port 325 located at the end of the arc-shaped groove 324. This design is particularly suitable for handling high-viscosity fluids and effectively avoids outlet blockage.

[0038] Finally, the detergent concentrate that has reached the predetermined concentration flowing out of the drain outlet 325 is received by the collection box 4 directly below it.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
