Abstract
Description
Technical Field
[0001] This utility model belongs to the field of quaternary ammonium salt detection technology, specifically relating to a quaternary ammonium salt leaching device for fabrics. Background Technology
[0002] Quaternary ammonium salts are cationic surfactants that, as disinfectants, cause microbial death by disrupting the outer membrane of bacteria, leading to the leakage of their contents. Quaternary ammonium salts are stable and easy to use, resulting in their widespread application. However, with further research, it has been discovered that quaternary ammonium salt compounds can cause problems such as asthma, allergic skin reactions, and vision impairment. Current methods for detecting quaternary ammonium salts generally employ ion chromatography, ultraviolet spectrophotometry, titration, gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-mass spectrometry (LC-MS). These methods all involve dissolving the quaternary ammonium salt to obtain a leachate, and then calculating the concentration of the quaternary ammonium salt by detecting the leachate. Therefore, the dissolution effect of quaternary ammonium salts directly affects the accuracy of detection. Quaternary ammonium salts are frequently used in the textile industry, widely used as softeners and antistatic agents, distinguished by their excellent softening, antistatic, bactericidal, and anti-yellowing properties. In conventional quaternary ammonium salt dissolution treatments, the fabric is directly added to the solvent for stirring and dissolution. Due to the poor dispersion caused by fabric aggregation and stirring, the dissolution effect of quaternary ammonium salts in the fabric is unstable, leading to a decrease in the accuracy of the quaternary ammonium salt concentration within the fabric. Utility Model Content
[0003] To address the problems in the existing technology, this utility model provides a quaternary ammonium salt dissolution device for fabrics, which solves the problem of unstable quaternary ammonium salt dissolution effect in fabrics. It utilizes the perforated mesh plate at the upper end and the perforated holes at the lower end of the cylindrical isolation plate to form upper and lower liquid flow channels. In conjunction with the rotating shaft and blades inside the cylindrical isolation plate, an internal liquid flow guide is formed, thereby ensuring that the liquid continuously flows through the fabric and improving the dissolution effect of the liquid and the fabric.
[0004] To achieve the above technical objectives, the technical solution of this utility model is as follows:
[0005] A quaternary ammonium salt leaching device for fabrics includes a leaching tank and a top cover. The leaching tank is a lidless tank, and the top cover completely covers the upper surface of the leaching tank. The top cover has a raised ring around its edge that can fit perfectly with the leaching tank.
[0006] A cylindrical partition plate is located at the center of the dissolution chamber, dividing the chamber into an inner space and an outer space. The cylindrical partition plate includes a positioning plate and a placement plate, which are detachably connected. The positioning plate is directly fixed to the inner bottom surface of the dissolution chamber, and multiple through holes are evenly distributed on its outer surface, ensuring complete communication between the inner and outer spaces. A perforated mesh plate is located in the middle section of the placement plate, with multiple fixing bolt groups at its upper and lower edges. The perforated mesh plate effectively ensures communication between the inner and outer spaces, and the fabric is fixed to the outer side of the perforated mesh plate using fixing screw bolt groups.
[0007] A motor is located at the center of the upper surface of the cover, and a rotating shaft is connected to the motor. The rotating shaft passes through the cover and enters the cylindrical isolation plate. The rotating shaft is located on the central axis of the cylindrical isolation plate, and its surface is provided with continuous blades.
[0008] The cylindrical partition plate is positioned at a certain distance from the top cover. The upper part of the cylindrical partition plate acts as a barrier to the liquid surface, which is the main reason for the liquid level difference between the inner and outer spaces. When the liquid level difference between the inner and outer spaces is large enough, the liquid pressure will exert excessive pressure on the fabric, causing damage. In some cases, the liquid level may even fall below the surface of the perforated mesh plate, causing the fabric to directly contact the air, resulting in changes and uncontrollable dissolution environment, leading to variations in dissolution effects and unstable test data. Furthermore, an excessively large liquid level difference can also result from excessively high motor rotation speed, leading to excessive liquid traction and a rapid increase in internal pressure, damaging the motor and stirring blades. This distance ensures the connectivity of the upper part of the cylindrical partition plate, enabling communication between the upper parts of the inner and outer spaces, thus improving the stability and lifespan of the equipment.
[0009] Furthermore, the outer diameter and inner diameter of the through-hole mesh plate and the positioning plate are the same. The lower surface of the through-hole mesh plate is provided with a positioning protrusion, and the upper surface of the positioning plate is provided with a positioning groove. The positioning protrusion and the positioning groove fit together.
[0010] The bottom end of the rotating shaft is close to the bottom surface of the dissolution tank, and the outer edge of the blades is close to the inner surface of the cylindrical partition plate. With the bottom end of the rotating shaft close to the bottom and the blades close to the inner surface of the cylindrical partition plate, the rotating shaft with blades will form a stable liquid flow rotation during the rotation of the motor, effectively reducing the dead volume of the internal space and helping to form complete liquid flow.
[0011] Furthermore, the upper end of the blade is higher than the upper end of the cylindrical partition plate, and the lower end is close to the inner bottom surface of the dissolution tank. During motor operation, the rotating shaft rotates stably under the drive of the motor, thereby driving the blade to rotate continuously. At this time, the rotating blade can drive the liquid to circulate in the inner space. With the cooperation of the perforated mesh plate and the upper and lower perforations, the liquid level difference between the inner and outer spaces can be achieved, and the liquid circulation is formed. The circulation of the liquid will inevitably lead to the liquid directly penetrating the fabric, thereby improving the stable and uniform contact between the fabric and the liquid.
[0012] As can be seen from the above description, this utility model has the following advantages:
[0013] 1. This utility model solves the problem of unstable quaternary ammonium salt dissolution effect in fabric. It utilizes the through-hole mesh plate at the upper part of the cylindrical isolation plate and the through-hole at the lower part to form upper and lower liquid flow channels. With the help of the rotating shaft and blades inside the cylindrical isolation plate, an internal liquid flow guide is formed, thereby ensuring that the liquid continuously flows through the fabric and improving the dissolution effect of the liquid and the fabric.
[0014] 2. This utility model utilizes the detachability of the placement plate on the positioning plate, and together with the fixing bolt group on the perforated mesh plate, the fabric is fixed on the perforated mesh plate. This not only achieves stable fabric usage, but also ensures complete fabric spreading, guaranteeing the repeatability of the dissolution effect of the dissolution device. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the dissolution device of this utility model. Detailed Implementation
[0016] Combination Figure 1 This document describes specific embodiments of the present invention in detail, but does not limit the scope of the claims of the present invention in any way.
[0017] like Figure 1 As shown, a quaternary ammonium salt leaching device for fabrics includes a leaching chamber 1 and a top cover 2. The leaching chamber 1 is a lidless chamber, and the top cover 2 completely covers the upper surface of the leaching chamber 1. The top cover 2 has a raised edge that faces downwards, which can fit perfectly with the leaching chamber 1. The combination of the top cover and the leaching chamber can transform the leaching chamber into a sealed stirring chamber, eliminating internal and external flow. At the same time, the raised edge of the top cover can play a positioning role, which not only ensures that the position of the top cover and the leaching chamber is relatively stable, but also prevents the top cover from automatically shifting when the motor of the top cover rotates, thus ensuring that the sealing state of the leaching chamber is completely stable.
[0018] A cylindrical partition plate 3 is disposed at the center of the dissolution chamber 1, dividing the dissolution chamber 1 into an inner space and an outer space. The cylindrical partition plate 3 includes a positioning plate 3-2 and a placement plate 3-1, which are detachably connected. The positioning plate 3-2 is directly fixed to the inner bottom surface of the dissolution chamber 1, and multiple through holes are evenly distributed on the outer surface of the positioning plate 3-2, ensuring complete communication between the inner and outer spaces. A perforated mesh plate 3-101 is disposed in the middle section of the placement plate 3-1. Multiple fixing bolt groups 3-102 are respectively provided on the upper and lower edges. The perforated mesh plate 3-101 can effectively ensure the communication between the inner and outer spaces. The outer side of the perforated mesh plate 3-101 is fixed with fabric by fixing screw bolt groups 3-102. The fabric completely covers the perforated mesh plate 3-101, which enhances the flow barrier between the inner and outer spaces, but does not completely seal them off. The cylindrical isolation plate 3 is at a certain distance from the top cover 2. This distance ensures the communication between the inner and outer spaces at the upper end of the dissolution tank 1, which helps to improve the flow of the dissolving liquid.
[0019] Furthermore, the outer and inner diameters of the perforated mesh plate 3-101 and the positioning plate 3-2 are the same. The lower surface of the perforated mesh plate 3-101 is provided with a positioning protrusion, and the upper surface of the positioning plate 3-102 is provided with a positioning groove. The positioning protrusion and the positioning groove fit together, ensuring that the perforated mesh plate is stably mounted on the positioning plate and will not shift or separate during the dissolution process. The stable fit between the positioning groove and the positioning protrusion provides excellent quick-release capability. The fabric can be fixed to the outer surface of the perforated mesh plate by disassembling it and using a set of fixing bolts. This not only utilizes the perforated mesh plate to determine the exposed area of the fabric but also provides good permeability. The area of the perforated mesh plate is stable. With the fixing bolt group located on the perforated mesh plate, the fabric covering the perforated mesh plate is fully spread out. The spread area is basically consistent with the outer surface of the perforated mesh plate, which has excellent area controllability. At the same time, the fabric is adhered and fixed to the outer surface of the cylindrical isolation plate, which can form sufficient contact with the liquid and improve the dissolution effect.
[0020] A motor 2-1 is centrally located on the upper surface of the cover 2, and a rotating shaft 2-2 is connected to the motor 2-1. The rotating shaft 2-2 passes through the cover and enters the cylindrical isolation plate 3. The rotating shaft 2-2 is located on the central axis of the cylindrical isolation plate 3, and its surface is provided with continuous blades 2-3. The bottom end of the rotating shaft 2-2 is close to the inner bottom surface of the dissolution tank 1, and the outer edge of the blades 2-3 is close to the inner surface of the cylindrical isolation plate 3. Furthermore, the upper end of the blades 2-3 is higher than the upper end of the cylindrical isolation plate 3, and the lower end is close to the inner bottom surface of the dissolution tank 1. During motor operation, the rotating shaft rotates stably under the drive of the motor, thereby driving the blades to rotate continuously. At this time, the rotating blades can drive the liquid to circulate in the inner space. With the cooperation of the perforated mesh plate and the upper and lower perforations, the liquid level difference between the inner and outer spaces can be achieved, and the liquid circulation is formed. The circulation of the liquid will inevitably lead to the liquid directly penetrating the fabric, thereby improving the stable and uniform contact between the fabric and the liquid.
[0021] During use, lift the top cover upwards and disassemble the shelf. Open the fixing bolt assembly, attach a piece of fabric slightly larger than the perforated mesh plate, and fix it by drilling holes according to the position of the fixing bolt assembly. Then, cut off the fabric area that exceeds the perforated mesh plate to ensure that the fabric area is consistent with the outer surface of the perforated mesh plate, thus accurately determining the fabric area. Fix the shelf with the fabric onto the positioning plate using the matching positioning groove and positioning protrusion to obtain a complete cylindrical isolation plate. Add the dissolving solution into the dissolving tank until the dissolving solution completely submerges the perforated mesh plate without exceeding the cylindrical isolation plate. At this point, close the top cover and insert the shaft and blades into the inner space. Finally, the motor is turned on, driving the shaft and blades on it to rotate. The blades gradually lift the liquid at the bottom of the shaft upwards. The different liquid resistances between the fabric on the perforated mesh plate and the perforations on the positioning plate cause the inner space to gradually rise. At this point, under the motor's action, the perforations draw liquid from the outer space into the inner space, while liquid in the fabric gaps flows from the inner space to the outer space, creating a convection effect. The placement of the blades near the inner surface of the cylindrical partition plate effectively improves the stability of the liquid flow within the partition plate, reduces internal dead volume, and effectively controls liquid circulation. The same effect is achieved when the motor rotates in the opposite direction, making the liquid level in the inner space lower than the liquid film in the outer space. This quaternary ammonium salt dissolution device not only accurately determines the fabric area, ensuring a constant fabric area, but also guarantees that the fabric is fully expanded and in full contact with the liquid, resulting in excellent dissolution performance and superior repeatability in repeated experiments.
[0022] It is understood that the above detailed description of this utility model is for illustrative purposes only and is not intended to limit the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effects; as long as the usage requirements are met, they are all within the protection scope of this utility model.
