Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wool and cashmere detection, and in particular relates to a liquid phase mixing device for wool and cashmere. Background Art
[0002] Cashmere refers to goat wool, which is composed of scales and cortex layers. The scales have smooth edges, cover the surface of the hair shaft, have large spacing, and a small opening angle. They are soft, smooth, and waxy, and have excellent thermal insulation effects. They are known as "soft gold" and "diamond fiber" and are precious textile materials. Cashmere and wool are mainly composed of keratin protein, with similar structures, and are difficult to identify qualitatively and quantitatively. Cashmere and wool are both composed of keratin protein, accounting for about 82%. Their cross-sectional distribution is divided into two levels, namely the scale layer on the outer surface and the cortex layer inside. There is no medullary layer structure. The edges of cashmere scales are rough and circular, and the scales overlap by about one-third, with small spacing and a large warping angle. The surface of cashmere scales is smooth and tile-like, with less overlap between scales, large spacing, and a small warping angle. The number of curls in cashmere fiber is less than that of cashmere, the curl depth is greater, and the wear resistance and tensile properties are poor.
[0003] The technology of identifying cashmere and wool by infrared spectroscopy was proposed in recent years. When samples are irradiated by infrared spectrum, they absorb infrared rays of corresponding wavelengths and produce corresponding absorption peaks. The absorption response value within a certain range is proportional to the thickness or concentration of the sample, and quantitative analysis is performed according to Beer's law. Mid-infrared spectroscopy mainly comes from the fundamental frequency transition of functional groups in material molecules. It has the characteristics of high signal intensity and high spectral resolution. Therefore, it is mostly used for mechanism research and qualitative analysis. Near-infrared spectroscopy mainly comes from the sum and harmonic frequency transitions of hydrogen-containing functional groups in material molecules. It has the characteristics of low signal intensity and low spectral resolution. It is often used for quantitative analysis. In infrared spectroscopy detection, the similar structure and similar composition of wool and cashmere result in low accuracy in the identification of characteristic peaks. Wool and cashmere themselves are in the form of monofilament fibers. Simple physical mixing is difficult to achieve the effect of homogeneous mixing, which can easily lead to poor internal and external homogeneity. Utility Model Content

[0007] The mixing barrel 2 is cylindrical as a whole, and the bottom longitudinal section 2-1 of the mixing barrel 2 is corrugated, and a sealing cover 2-2 for sealing is arranged on the top, and a handle 2-3 is arranged on the sealing cover 2-2; the bottom longitudinal section is corrugated, and the center of the bottom of the mixing barrel is located at the lowest end of the corrugated structure. During the stirring process, the corrugated bottom of the mixing barrel drives the flow change of the liquid at the bottom during the rotation process, and the flow change of the bottom liquid drives the flow change of the liquid in the entire mixing barrel, thereby realizing the liquid phase stirring effect of the mixing barrel; the handle 2-3 is arranged on the upper surface of the sealing cover of the mixing barrel, which can facilitate the sealing and disassembly of the sealing cover, which not only improves the practicability of the mixing barrel, but also meets the sealing performance during the liquid phase stirring process, and solves the volatility of the liquid in the liquid phase mixing device.
[0008] A groove 2-21 is provided on the outer circumference of the sealing cover 2-2, and a rubber ring is provided in the groove 2-21; further, the cross-section of the groove 2-21 is semicircular, and the groove with a semicircular structure can achieve excellent positioning effect, ensuring that the rubber ring is fixed in the groove and reducing the displacement of the rubber ring during the sealing process; secondly, the cross-section of the groove is semicircular and the surface is relatively smooth, which can achieve a stable sealing effect and ensure the sealing contact between the inner wall of the groove and the rubber ring; the outer side of the rubber ring slightly protrudes from the groove, and the outward layer of the rubber ring is serrated, and the rubber ring with a serrated structure can form a close contact with the inside of the mixing barrel, and cooperate with the outer side of the rubber ring to protrude from the groove, which effectively realizes the extrusion deformation of the rubber ring and ensures the close connection between the outer side of the rubber ring and the inner wall of the mixing barrel, thereby achieving excellent sealing.
[0009] The sealing cover 2-2 is provided with a pressure relief pipe 2-22, and the pressure relief pipe 2-22 penetrates the entire sealing cover to form an internal and external connection.

Therefore, a pressure relief pipe is provided here, and the pressure relief pipe is connected to the external pump and recovery chamber to form a good connection. As the air pressure of the pump is extracted, the pressure in the mixing barrel drops rapidly, thereby increasing the volatilization rate of the liquid, and then it is recovered by the recovery chamber, finally achieving solid-liquid separation in the mixing barrel, and the liquid in the recovery chamber can also be reused. During the liquid phase mixing process, the sealing cap closes the pressure relief pipe to ensure that the mixing barrel forms a constant pressure sealing structure, which is conducive to the stable mixing of wool and cashmere; when the sealing cap is opened, the pressure relief pipe is connected to the external device through a pipeline to form a vacuum device, which increases the liquid volatility and uses the low boiling point of the liquid itself to achieve solid-liquid powder, which also greatly reduces the accumulation of residual liquid.
[0010] From the above description, it can be seen that the utility model has the following advantages:
[0011] 1. The present invention solves the difficulty of mixing cashmere and wool.

[0013] 3.

[0015] Figure 2 It is a structural schematic diagram of the sealing cover in the utility model. DETAILED DESCRIPTION
[0016] Combination Figure 1 and Figure 2 , describes in detail a specific embodiment of the utility model, but does not limit the claims of the utility model.
[0017] like Figure 1 and Figure 2 As shown, a liquid phase mixing device for wool and cashmere comprises: a device body 1 and a stirring barrel 2 located in the device body 1;
[0018] The stirring barrel 2 is cylindrical as a whole, and the longitudinal section of the bottom of the stirring barrel 2 is corrugated, and in the longitudinal section, the center of the bottom of the stirring barrel is located at the lowest end of the corrugated structure. During the stirring process, the height difference in the structure will form a certain longitudinal flow dynamics, thereby driving the liquid flow to form an omnidirectional flow, and in conjunction with the rotation of the entire stirring barrel, the liquid flow in the stirring barrel is realized, and a mixing system without stirring blades is realized; a sealing cover 2-2 is provided at the top of the stirring barrel for sealing, and a handle 2-3 is provided on the sealing cover 2-2. The setting of the handle provides a fulcrum for the sealing cover, which is convenient for disassembly of the sealing cover; a groove 2-21 is provided on the side of the sealing cover 2-2, and a rubber ring with a serrated outer side is provided in the groove, and the rubber ring has a serrated outer side. The outer side of the rubber ring is slightly higher than the groove. The setting of the groove and the rubber ring fully utilizes the extrusion characteristics of the rubber to ensure the sealing effect of the sealing cover and effectively prevent the volatilization of the internal liquid. At the same time, it should be noted that the rubber ring with a serrated structure on the side of the sealing cover forms a force-deformation seal with the inside of the mixing barrel, and the rubber ring can be tightly attached to the inner wall of the groove based on the mutual force to form a tight connection structure. The sealing cover 2-2 is provided with a pressure relief pipe 2-22 and a sealing cap 2-23 located on the pressure relief pipe 2-22 to seal. The pressure relief pipe 2-22 penetrates the pressure relief pipe 2-22 to ensure the connectivity in the mixing barrel and is temporarily closed with the sealing cap. At the same time, the pressure relief pipe 2-22 is connected to the external pumping machine and the recovery chamber.
[0019] A bottom plate 3 is provided at the bottom of the device body 1, and a plurality of rollable balls 4 are inlaid on the upper surface of the bottom plate 3, and a plurality of balls emerge from the upper surface of the bottom plate 3, and the mixing barrel 2 is placed on the balls 4. During use, two identical stirring structures 5 are symmetrically provided on the side of the mixing barrel 2, and the stirring structure includes a rotating shaft 5-2, a first rotating wheel 5-1, a second rotating wheel 5-3 and a switchable motor 5-4. The rotating shaft 5-2 is vertically arranged and parallel to the mixing barrel 2. The first rotating wheel 5-1 and the second rotating wheel 5-3 are fixed on the rotating shaft 5-2. The first rotating wheel 5-1 and the second rotating wheel 5-3 are parallel to each other, and the sides of both are in contact with the outer wall of the mixing barrel 2. The switchable motor is fixed at one end of the rotating shaft 5-2 and drives the rotating shaft to rotate at a uniform speed. During use, after the switchable motor is turned on The motor drives the rotating shaft to rotate at a uniform speed, and ensures that the first rotating wheel and the second rotating wheel rotate coaxially. It should be noted that the first rotating wheel and the second rotating wheel contact the mixing barrel from the upper and lower positions respectively, and drive the mixing barrel to rotate by means of contact friction. At this time, a rollable ball is arranged at the bottom of the mixing barrel to ensure that the mixing barrel always remains stable during the rotation process and prevents hard friction between the mixing barrel and the bottom plate. The rolling friction brought by the ball effectively reduces the friction force and improves the use efficiency of the mixing barrel. The stirring mechanism is symmetrically set on both sides of the mixing barrel to form a multi-angle connection between the mixing barrel and the stirring mechanism, which can not only clamp the mixing barrel and prevent the problem of displacement of the mixing barrel, but also the stirring structure can form multi-point friction, thereby improving the driving force for the rotation of the mixing barrel and reducing the problem of idling of the rotating shaft.
[0020] The method for using the liquid phase mixing device for wool and cashmere is as follows: step 1, weighing wool and cashmere in proportion and putting them into a stirring barrel, and adding ethyl acetate until the stirring barrel covers two-thirds of the stirring barrel; the wool and cashmere are weighed and put into the stirring barrel in proportion to ensure the ratio of wool and cashmere, and then ethyl acetate is added to the stirring barrel to obtain a suspension, wherein the ethyl acetate not only wets the wool and cashmere, but also the amount used far exceeds the quality of the wool and cashmere; step 2, sealing the stirring barrel with a sealing cover, and sealing the pressure relief pipe with a sealing cap, turning on the switchable motor of the stirring structure, and the switchable motor drives the first rotating wheel and the second rotating wheel to form synchronous rotation through the rotating shaft, and finally drives the stirring barrel to run stably. There are two stirring structures here, and they are symmetrically arranged on both sides of the stirring barrel. The two stirring structures are opened synchronously to form an upper and lower multi-point drive, which ensures that the stirring barrel rotates stably while the stirring barrel is limited by the space of the two stirring structures, thereby eliminating the problem that the stirring barrel is limited by the space of the two stirring structures. Movement of the stirring barrel; The corrugated structure at the bottom of the stirring barrel can drive the flow of ethyl acetate, promote the flow of ethyl acetate by increasing the liquid flow, and improve the dispersion of wool and cashmere in ethyl acetate. The fiber structure of wool and cashmere here is completely opened, and fully dispersed and mixed during the liquid flow process, so as to achieve the mixing and interlacing of wool and cashmere in the liquid phase system, so that the wool and cashmere form a homogeneous physical mixture; Step 3, open the sealing cap on the sealing cover, and connect it with the external pumping machine and the recovery chamber, open the pumping machine and slowly extract the pressure in the stirring barrel, and the ethyl acetate in the process is converted from liquid to gas during the negative pressure process for air pressure compensation, so that a large amount of ethyl acetate is converted into gas and sucked away by the pumping machine, and finally accumulated in the recovery chamber for reuse. At this time, the wool and cashmere in the stirring barrel form a homogeneous mixture, and as the pressure decreases, the ethyl acetate volatilizes in situ, and the mixed state of wool and cashmere remains unchanged. The ethyl acetate in the recovery chamber can be reused in the stirring barrel for liquid phase mixing of wool and cashmere. The liquid phase mixing device can utilize the fluffy and loose structure of wool and cashmere in the liquid phase to achieve a homogeneous dispersion effect, solving the problem of inhomogeneous mixing of wool and cashmere solids. At the same time, by utilizing the insolubility of ethyl acetate in wool and cashmere and the volatility of ethyl acetate itself, non-destructive drying is performed at room temperature under the action of a vacuum press, thereby achieving solid-liquid separation.

Those skilled in the art should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
