Abstract
Description
Technical Field
[0001] This utility model relates to the field of leather fatliquoring agent processing technology, and in particular to a leather fatliquoring agent emulsification device. Background Technology
[0002] In the leather production process, fatliquoring is a key step that gives leather its softness, fullness, and elasticity. Fatliquoring agent emulsification equipment is an important device for achieving uniform dispersion of fatliquoring agents and forming a stable emulsion. However, traditional leather fatliquoring agent emulsification equipment has many problems in practical applications, which affect the leather fatliquoring effect and production efficiency.
[0003] Traditional equipment suffers from insufficient emulsification uniformity. Relying on a single stirring mode, it struggles to address the density differences and interfacial tension characteristics between oils and water in leather fatliquoring agents, leading to poor emulsion stability, poor oil penetration, and consequently, negatively impacting leather quality. For high-viscosity materials, if the stirring range cannot automatically expand according to operating conditions, the materials are difficult to mix thoroughly, easily resulting in localized over-mixing and under-mixing in other areas. This can cause localized overheating, increasing energy consumption and potentially affecting product quality. On the other hand, when processing low-viscosity materials, if the stirring range cannot be reduced, a large amount of ineffective stirring occurs, wasting energy and failing to achieve precise mixing. This not only fails to guarantee good mixing results but also reduces the equipment's energy efficiency ratio, significantly increasing production costs.
[0004] Therefore, a leather fatliquoring emulsification device was designed. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing a leather fatliquoring agent emulsification device, which solves the problem that the stirring range cannot be automatically adjusted according to the viscosity of the material.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A leather fatliquoring agent emulsification device includes a tank. A main rotating rod is rotatably mounted inside the tank. Four identical stirring components are fixedly mounted on the outer wall of the main rotating rod. Each stirring component includes a secondary rotating rod fixedly sleeved on the outer wall of the main rotating rod. A connecting rod 1 is hinged to the other end of the secondary rotating rod. A connecting rod 2 is hinged to the bottom end of the connecting rod 1. An insert rod is fixedly mounted on the inner wall of the connecting rod 2. A stirring cone is fixedly mounted at both ends of the insert rod.
[0008] Preferably, the four sets of stirring components are distributed at equal intervals and present an overall spiral distribution.
[0009] Preferably, four sets of stirring blades are fixedly sleeved on the outer wall of the main rotating rod. Each set of stirring blades is distributed at intervals with the stirring assembly. Each set of stirring blades is composed of three rectangular plates arranged in a circumferential array. A scraper is fixedly sleeved at the bottom end of the main rotating rod, and the scraper abuts against the inner wall of the tank.
[0010] Preferably, a top cover is fixedly installed on the top of the tank, and a protective cover is fixedly installed on the top of the top cover by bolts. The top end of the main rotating rod extends into the protective cover and is rotatably connected to the top cover.
[0011] Preferably, a motor is fixedly installed on the top inner wall of the protective cover, and the output shaft of the motor is fixedly connected to the top end of the main rotating rod.
[0012] Preferably, each of the connecting rods consists of two thin plates, which are rotatably connected by a cylinder, and an oblong groove is provided on the outer wall of the lower thin plate.
[0013] Preferably, each stirring cone consists of three rectangular rods and one sphere, with one end of each of the three rectangular rods fixedly connected to the sphere, forming an umbrella shape.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This invention automatically adjusts the stirring range by changing the rotational speed of the main rotor, eliminating the need for additional control mechanisms. In high-viscosity stages, the increased rotational speed of the main rotor increases centrifugal force, causing the stirring cone and connecting rod to form a near-horizontal shape, thus expanding the stirring range and preventing energy loss due to localized overheating. When processing low-viscosity materials, the rotational speed of the main rotor is reduced, shrinking the stirring range. This design, which automatically adjusts the stirring range according to the material viscosity, achieves precise stirring, ensuring effective mixing while reducing ineffective stirring power consumption. This significantly improves the energy efficiency ratio of the device and lowers production costs. Attached Figure Description

Example
[0027] Please see Figure 1-5A leather fatliquoring emulsification device includes a tank 1. A main rotating rod 3 is rotatably mounted inside the tank 1. Four identical stirring components are fixedly mounted on the outer wall of the main rotating rod 3. Each stirring component includes a secondary rotating rod 4 fixedly sleeved on the outer wall of the main rotating rod 3. A scraper 32 is fixedly sleeved at the bottom end of the main rotating rod 3, and the scraper 32 abuts against the inner wall of the tank 1. A connecting rod 41 is hinged to the other end of the secondary rotating rod 4. A second connecting rod 42 is hinged to the bottom end of the first connecting rod 41. An insert rod 43 is fixedly mounted on the inner wall of the second connecting rod 42. Stirring cones 44 are fixedly mounted at both ends of the insert rod 43. The four stirring components are evenly spaced and arranged in a spiral pattern. The outer wall of the main rotating rod 3 is fixedly sleeved with four sets of stirring components. The mixing blades 31 are spaced apart from the mixing components, and each set of mixing blades 31 consists of three rectangular plates arranged in a circumferential array. A top cover 2 is fixedly installed on the top of the tank body 1, and a protective cover 21 is bolted to the top of the top cover 2. The top end of the main rotating rod 3 extends into the protective cover 21 and is rotatably connected to the top cover 2. A motor 22 is fixedly installed on the top inner wall of the protective cover 21, and the output shaft of the motor 22 is fixedly connected to the top end of the main rotating rod 3. Each connecting rod 42 consists of two thin plates, which are rotatably connected by a cylinder. A waist-shaped groove is opened on the outer wall of the lower thin plate. Each mixing cone 44 consists of three rectangular rods and a sphere. One end of the three rectangular rods is fixedly connected to the sphere, and the whole is umbrella-shaped.
[0028] The unique layout of four sets of stirring components, evenly spaced and arranged in a spiral pattern, greatly enhances the uniformity of stirring. The even spacing ensures the four stirring components are uniformly distributed within tank 1, enabling simultaneous stirring of materials at different locations and preventing excessive local variations in stirring intensity. In contrast, some previous devices suffered from uneven distribution of stirring components, leading to over-stirring in some areas and under-stirring in others, affecting emulsion quality. This device's layout ensures that the material receives uniform stirring force within tank 1, while the spiral distribution creates a spiral flow of material during stirring. This increases the relative movement and mixing opportunities between materials; when the main rotor 3 drives the four sets of stirring components to rotate, the materials can come into more full contact and mix under the action of spiral flow, further promoting the uniform dispersion of materials; the four sets of stirring blades 31 fixedly sleeved on the outer wall of the main rotor 3 are distributed at intervals with the stirring components, and the two work together to form a highly efficient stirring system; each set of stirring blades 31 is composed of three rectangular plates in a circumferential array, and this structure can generate large shear force and stirring force during rotation; when the motor 22 starts and the output shaft drives the main rotor 3 to rotate, the four sets of stirring blades 31 first align. The solvent in the center of tank 1 undergoes initial mixing and stirring, breaking down and initially dispersing large pieces of material. The stirring assembly then further refines the mixing. The spaced distribution of the stirring blades 31 and the stirring assembly creates a layered mixing process. The stirring blades 31 perform initial processing, followed by deep mixing by the stirring assembly, significantly improving mixing efficiency and shortening emulsification time. The umbrella-shaped structure increases the contact area between the stirring cone 44 and the material. As the stirring cone 44 rotates, it can contact more material simultaneously, improving mixing efficiency. The design of the three rectangular rods ensures that the stirring cone 44 rotates... It can generate stronger stirring and shearing forces; when stirring high-viscosity materials, the rectangular rod can effectively break up lumps and particles in the material, promoting uniform mixing of the material. The spherical design can reduce the frictional resistance between the stirring cone 44 and the material during rotation, reduce energy consumption, and improve the smoothness of stirring. Through the contact between the scraper 32 and the inner wall of the tank 1, as the main rotating rod 3 rotates, the scraper 32 will continuously scrape the inner wall of the tank 1, which can promptly scrape off the material attached to the inner wall and make it re-participate in the stirring and mixing process, ensuring the uniformity of the material and the accuracy of the proportion in the emulsification device.
[0029] The solvent to be mixed is added into tank 1 through the pipe on the side wall of tank 1, and then motor 22 is started. The output shaft of motor 22 rotates, causing the stirring blade 31 to rotate.
[0030] First, the main rotating rod 3 drives the four sets of stirring blades 31 to rotate and stir, mixing the solvent located in the center of the tank 1;
[0031] The main rotating rod 3 rotates while driving the four auxiliary rotating rods 4 to rotate together. The auxiliary rotating rods 4 drive the connecting rod 1 41 and the connecting rod 2 42 to rotate together. The connecting rod 2 42 drives the insert rod 43 and the stirring cone 44 to rotate. Since the connecting rod 1 41 is hinged to the connecting rod 2 42 and the connecting rod 2 42 is hinged to the insert rod 43, the stirring range of the rotating insert rod 43 and the stirring cone 44 in the tank 1 can be changed with the rotation speed of the main rotating rod 3. When the rotation speed of the main rotating rod 3 is faster, the insert rod 43 and the stirring cone 44 are driven by the centrifugal force of the rotation of the main rotating rod 3, so that the stirring cone 44 and the connecting rod 1 41 form a near-horizontal shape, the stirring range is expanded, the stirring range is expanded by speeding up the stirring in the high viscosity stage, and energy loss caused by local overheating is avoided.
[0032] If the main rotating rod 3 is reduced, the connecting rod 42 will tilt downward under gravity, transforming the horizontal state of the connecting rod 41 into a near-L-shaped rotation, thus reducing its stirring range. When processing low-viscosity materials, reducing the rotation speed will shrink the stirring range and reduce ineffective stirring power consumption.
[0033] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
