Description
Technical Field
[0001] The utility model relates to the field of functional textile effect detection devices, in particular to a simple device for detecting the ammonia removal effect of fabrics. Background Art
[0002] In daily life, people often come into contact with various items that may produce odors, such as clothing, bedding, car interiors, etc. These odors not only affect people's comfort, but also pose a potential threat to health. Among them, ammonia is a very representative odor substance.
[0003] The commonly used method for detecting the reduction rate of ammonia concentration is the detection tube method in GB / T 33610-2019 "Determination of Deodorizing Properties of Textiles". Specifically, the sample and ammonia are placed in a closed container, and the ammonia concentration in the sampling bag containing the sample and the blank sampling bag are measured using a detection tube at specified time intervals to calculate the reduction rate of ammonia concentration.
[0004] Although the above method for detecting the reduction rate of ammonia concentration can detect the reduction rate of ammonia concentration, the operation of this inspection method is relatively cumbersome, and the cost of detection is high, which is not convenient for personnel to adopt in any occasion under any conditions. Utility Model Content
[0005] Based on this, the purpose of the present invention is to provide a simple device for detecting the ammonia removal effect of fabrics, so as to solve the technical problems that the traditional method for detecting the reduction rate of ammonia concentration is complicated to operate and consumes high resources.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a simple device for detecting the ammonia removal effect of fabrics, comprising a detection body, a first liquid tank is provided inside the detection body, and a heating plate is installed inside the first liquid tank, a feeding port is installed on the top of the detection body, and a feeding pipe is provided inside the detection body, and the feeding pipe connects the feeding port and the first liquid tank, a ventilation pipe is provided on the top of the first liquid tank, and one end of the ventilation pipe is connected to the second liquid tank, a cover is provided on the top of the feeding port, a slide is provided inside the detection body, and the slide is located in the middle of the ventilation pipe, a filter frame is movably installed inside the slide, an exhaust pipe is provided on the top of the detection body, and an exhaust pipe is installed at the bottom end of the exhaust pipe, and the exhaust pipe connects the exhaust pipe and the interior of the second liquid tank.
[0007] By adopting the above technical solution, the traditional method for detecting the reduction rate of ammonia concentration is complicated to operate and consumes a lot of resources. Ammonia water and a mixed phenolphthalein aqueous solution are added to the first liquid tank and the second liquid tank respectively through the feeding port and the exhaust pipe. The controller sets the heating plate to constant temperature heating and fixed magnetic stirring speed. The heated and volatilized ammonia flows through the ventilation pipe through the filter plate to reach the inside of the catheter. The ammonia reacts with the mixed phenolphthalein aqueous solution to change color. The degree of color change of the phenolphthalein solution in the second liquid tank is observed through the second water viewing window to judge the fabric's removal effect on ammonia.
[0008] The utility model is further configured such that a groove is provided inside the filter frame, and a filter sheet is movably installed inside the groove.
[0009] By adopting the above technical solution, personnel can add or remove filter discs inside the filter frame according to experimental requirements. The grooves opened inside the filter frame make it convenient for personnel to install and remove filter discs inside the filter frame.
[0010] The utility model is further configured such that a rubber pad is installed on the outer wall of the filter frame, and a slot matching the rubber pad is opened on the top of the detection body.
[0011] By adopting the above technical solution, ammonia will flow through the filter frame during the experiment. In order to prevent ammonia from escaping from the gap between the filter frame and the chute, a rubber pad is installed on the outer wall of the filter frame. When the filter frame is inserted into the chute, the rubber pad is squeezed into the slot, so that the filter frame inserted into the chute can have good sealing performance.
[0012] The present invention is further configured such that a controller is installed on one side of the detection body, and the controller controls the heating temperature of the heating plate and the rotation speed of the magnetic stirrer.
[0013] By adopting the above technical solution, the operator can adjust the heating temperature of the heating plate through the controller according to the experimental requirements, so that the ammonia water in the first liquid tank can be evenly heated to produce ammonia gas. At the same time, the constant heating temperature and fixed magnetic stirring speed can reduce the error between the gas volume and gas rate of ammonia passing through the filter frame in different group experiments.
[0014] The present invention is further configured such that a conduit is provided inside the second liquid tank, and the top of the conduit is communicated with one end of the ventilation pipe.
[0015] By adopting the above technical solution, during the experiment, ammonia gas inside the ventilation pipe enters the second liquid tank through the conduit, and contacts and reacts with the mixed phenolphthalein aqueous solution in the second liquid tank. Because the bottom end of the conduit is close to the bottom of the second liquid tank and the magnetic stirrer continuously stirs the liquid, the contact between the ammonia gas and the mixed phenolphthalein aqueous solution is increased, allowing the ammonia gas to fully react with the mixed phenolphthalein aqueous solution.
[0016] The present invention is further configured such that a first liquid drain pipe and a second liquid drain pipe are provided at the bottom of the detection body, and the first liquid drain pipe and the second liquid drain pipe are communicated with the first liquid tank and the second liquid tank respectively.
[0017] By adopting the above technical solution, the operator can discharge the liquid inside the first liquid tank and the second liquid tank respectively by controlling the valves of the first liquid drain pipe and the second liquid drain pipe, which is convenient for the operator to perform cleaning and other experiments.
[0018] The present invention is further configured such that a heat insulating sheet is provided on the inner wall of the first liquid tank, and the heat insulating sheet is located on the outer wall of the heating sheet.
[0019] By adopting the above technical solution, when the heating plate heats the ammonia water inside the first liquid tank at a constant temperature, heat is generated inside the first liquid tank, and the insulation plate insulates and preserves the heat, which can reduce a large amount of heat loss.
[0020] The present invention is further configured such that a first water viewing window and a second water viewing window are provided on one side of the detection body, and the internal conditions of the first liquid tank and the second liquid tank can be observed through the first water viewing window and the second water viewing window respectively.
[0021] By adopting the above technical solution, the first water viewing window and the second water viewing window provided on one side of the detection body are transparent. Personnel can observe the internal conditions of the first liquid tank and the second liquid tank through the first water viewing window and the second water viewing window, thereby being able to understand the situation during the experiment and facilitating personnel's control of individual experimental data.
[0022] The present invention is further configured such that a first magnetic stirrer is installed at the bottom of the first liquid bin, and a second magnetic stirrer is installed at the bottom of the second liquid bin.
[0023] By adopting the above technical solution, the operator adjusts the stirring rate of the first magnetic stirrer through the controller to stir the ammonia water at a uniform speed, and at the same time, the second magnetic stirrer stirs the phenolphthalein solution at a uniform speed, so that the ammonia gas can fully react with the phenolphthalein solution. At the same time, the magnetic stirrer stirs evenly to uniformly mix the phenolphthalein solutions inside the second liquid tank, which facilitates the subsequent color comparison of the phenolphthalein solutions.
[0024] In summary, the present invention has the following beneficial effects:
[0025] 1. The utility model solves the problem that the traditional method for detecting the reduction rate of ammonia concentration is relatively complicated and consumes high resources by providing a feeding pipe, a ventilation pipe, a filter frame, an exhaust pipe, a first liquid tank and a second liquid tank. Ammonia water and a mixed phenolphthalein aqueous solution are respectively added to the first liquid tank and the second liquid tank through a feeding port and an exhaust pipe. The controller sets a heating plate for constant temperature heating and a fixed magnetic stirring speed. The heated and volatilized ammonia flows through the ventilation pipe through the filter plate to the inside of the conduit. The ammonia reacts with the mixed phenolphthalein aqueous solution to change color. The ammonia removal effect of the fabric on ammonia is judged by observing the degree of color change of the phenolphthalein solution.
[0026] 2. The utility model accurately controls the operating conditions through the controller, heating plate, magnetic stirrer and filter frame, thereby reducing the experimental variables caused by operational differences and causing the experimental results to be incomparable, making the experimental results more rigorous. The operator sets the heating temperature and magnetic stirring of the heating plate through the controller. The two groups of experiments weigh ammonia water of the same concentration and the same mass to ensure that the amount of ammonia volatilized by heating in the two groups of experiments remains consistent, which is beneficial for the operator to subsequently judge the removal effect of ammonia on the fabric by comparing the speed and degree of color change of the solution of the blank sample group and the experimental sample group. In addition, the filter frame is installed in the middle of the ventilation duct, which is convenient for personnel to install and remove the filter. BRIEF DESCRIPTION OF THE DRAWINGS
