Description

Technical Field

[0001] This utility model relates to the field of textile fiber content detection technology, specifically to a textile fiber dissolving bottle. Background Technology

[0002] In the detection of fiber content in textiles, the most common and efficient method is chemical dissolution quantitative analysis. This method involves dividing the textile into multiple small samples, drying and weighing them, then transferring the samples to an Erlenmeyer flask, adding a specified reagent to dissolve them, filtering out the residue, drying it, and weighing the remaining weight. By comparing the original dry weight of the sample with the dry weight of the residue, the percentage of that component can be determined.

[0003] For dissolution, one conical flask corresponds to one sample. When there are many samples, inspectors need to operate on each sample individually, including placing the sample, pouring reagents, sealing the flask, placing it in the designated experimental environment, water bath or shaking, and after the test, removing the samples one by one, cleaning the conical flask, filtering the samples, and finally drying them in an oven. When the testing volume is large, inspectors will have to repeat the above process continuously, which is very tedious, time-consuming and labor-intensive. In addition, when performing the above actions, inspectors must repeatedly verify the correspondence between the conical flask and the sample to prevent confusion of experimental data, and may even have to make marks on draft paper to ensure that the weighing data of the dissolved sample can accurately correspond to the weighing data before dissolution, which consumes a lot of manpower. Therefore, there is an urgent need to design a textile fiber dissolution bottle that can dissolve multiple samples simultaneously, reducing manpower and improving work efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a textile fiber dissolving bottle that, together with a shaker, a constant temperature water bath and other equipment, can dissolve multiple samples, reduce manpower and improve work efficiency.

[0005] The purpose of this utility model is achieved as follows:

[0006] A textile fiber dissolving bottle includes a bottle body, an elastic filter screen, and filter bags. The bottle body has a small opening and a large belly, and is a split type, including an upper cylindrical bottle body and a lower round-bellied bottle body. The round-bellied bottle body is provided with multiple filter bags containing samples. The elastic filter screen is fixed at the threaded connection between the round-bellied bottle body and the cylindrical bottle body.

[0007] Preferably, the top of the round-bellied bottle body is provided with an internal thread, the bottom of the cylindrical bottle body is provided with an external thread, and the inner side of the internal thread of the round-bellied bottle body is provided with a step, on which the elastic filter is placed.

[0008] Preferably, the top of the round-bellied bottle body tapers towards the center, the ratio of the maximum outer diameter to the height of the round-bellied bottle body is 1.8-2.2, and the ratio of the maximum outer diameter to the minimum outer diameter of the round-bellied bottle body is 3-5.

[0009] Preferably, the bottle wall of the round-bellied bottle is also provided with an air inlet with a valve, and the air inlet is connected to an air pipe.

[0010] Preferably, a sealing ring is provided at the connection between the cylindrical bottle body and the round-bellied bottle body, and the sealing ring is fitted onto the external thread of the cylindrical bottle body.

[0011] Preferably, the bottom surface of the round-bellied bottle is a conical surface with a high center and low edges.

[0012] Preferably, the filter bags are marked with serial numbers, and each filter bag has a different serial number, which can be marked with numbers or letters.

[0013] Preferably, the cylindrical bottle body and the round-bellied bottle body are made of acid and alkali resistant polypropylene material, which is transparent and colorless.

[0014] The beneficial effects of this utility model are:

[0015] When used with equipment such as a shaker, multiple samples can be dissolved, reducing manpower and improving work efficiency. The bottle has a small mouth and a large belly, which can meet the needs of accommodating multiple samples at one time. The bottle is designed with a cylindrical body and a round belly with threaded connection, and an elastic filter screen is fixed at the threaded connection. This not only prevents the filter bag from floating during dissolution and ensures that multiple samples are simultaneously below the reagent liquid level for full dissolution, but also allows for preliminary filtration and washing of the filter bag after dissolution, which greatly improves work efficiency.

[0016] The filter bags are marked with serial numbers. Each filter bag has a different serial number and can be marked with numbers or letters. This will prevent confusion among multiple samples, ensure the reliability of the original data, and avoid confusion between samples.

[0017] The bottle is visualized, allowing for timely intervention in cases such as sample detachment or entanglement. Attached Figure Description

[0020] Figure 3 This is a schematic diagram of the structure of an embodiment 2 of the present invention, which is a textile fiber dissolving bottle.

[0021] The components include: 1. Elastic filter screen; 2. Filter bag; 3. Cylindrical bottle body; 4. Round bottle body; 4.1 Air inlet; 5. Sealing ring; 6. Silicone plug; 7. Air tube. Detailed Implementation Example 1

[0022] See Figure 1 and Figure 2 This utility model relates to a textile fiber dissolving bottle, comprising a bottle body, an elastic filter screen 1, and filter bags 2. The bottle body has a small opening and a large belly. The bottle body is of a split type, comprising an upper cylindrical bottle body 3 and a lower round-bellied bottle body 4. The round-bellied bottle body 4 contains multiple filter bags 2 containing samples. The round-bellied bottle body 4 and the cylindrical bottle body 3 are connected by threads. The top of the round-bellied bottle body 4 has an internal thread, and the bottom of the cylindrical bottle body 3 has an external thread. The inner side of the internal thread of the round-bellied bottle body 4 has a step. The elastic filter screen 1 rests on the step. The liquid level of the dissolving solution is not lower than that of the elastic filter screen 1. The elastic filter screen 1 limits the filter bags 2 inside the round-bellied bottle body 4 to prevent the filter bags 2 from floating.

[0023] The inner bottom surface of the round-bellied bottle 4 is a conical surface with a higher center and lower edges, which promotes contact between the filter bag 2 and the inner wall of the round-bellied bottle 4, accelerates dissolution, and improves overall stability, preventing the bottle from tipping over. The top of the round-bellied bottle 4 tapers towards the center, and the top dimensions of the round-bellied bottle 4 are adapted to the bottom dimensions of the cylindrical body 3. The ratio of the maximum outer diameter to the height of the round-bellied bottle is 1.8-2.2, and the ratio of the maximum outer diameter to the minimum outer diameter is 3-5, which can meet the requirement of accommodating multiple samples at one time.

[0024] The lower end face of the external thread of the cylindrical bottle body 3 abuts against the elastic filter screen 1, thereby fixing the elastic filter screen 1 inside the bottle body. The split design of the bottle body has three functions: firstly, it facilitates the installation and removal of the elastic filter screen 1; secondly, it allows for the selection of cylindrical bottle bodies of different heights according to different oscillation speeds, effectively preventing the solution from overflowing; and thirdly, it makes it easy for the experimenter to hold.

[0025] A sealing ring 5 is also provided at the connection between the cylindrical bottle body 3 and the round bottle body 4. The sealing ring 5 is fitted onto the external thread of the cylindrical bottle body 3 to prevent leakage.

[0026] The top of the cylindrical bottle 3 is equipped with a silicone stopper 6 to further improve the safety of dissolution.

[0027] To facilitate differentiation, the filter bags 2 are marked with serial numbers. Each filter bag 2 has a different serial number and can be marked with numbers or letters.

[0028] The mesh of the elastic filter 1 is made of polypropylene yarn, which has excellent acid and alkali resistance and is stable in various common reagents, such as 75% sulfuric acid, sodium hypochlorite reagent, and 20% hydrochloric acid solution. The mesh edge is bound with stainless steel wire to facilitate the fixation of the elastic filter inside the bottle. During the dissolution process, the elastic filter limits the position of the filter bag, preventing the filter bag containing the sample from floating and ensuring it is completely submerged in the solution. After dissolution, the elastic filter can simultaneously perform preliminary filtration and washing of multiple filter bags containing samples.

[0029] The cylindrical bottle body 3 and the round-bellied bottle body 4 are made of acid and alkali resistant polypropylene material, which is transparent and colorless, making it easy for experimental personnel to observe the dissolution process in real time.

[0030] Operating instructions:

[0031] After drying and weighing, the sample is placed in a polypropylene filter bag and sealed with polypropylene thread.

[0032] Insert the filter bags into the round-bellied bottle, shake to spread or disperse the filter bags at the bottom of the round-bellied bottle, place the elastic filter screen, screw on the cylindrical bottle body, add the dissolving solution, and cover with the silicone stopper.

[0033] Place the bottle into a shaker or other equipment for dissolution experiments. During the dissolution process, carefully observe the sample. If the sample becomes entangled or adheres to a certain spot and fails to be submerged, intervene promptly.

[0034] After dissolution is complete, remove the silicone stopper and pour out the solution. Pour water into the bottle until it is full, then pour it out. Repeat this process more than 10 times to complete the initial filtration and washing of the sample.

[0035] After filtration, remove the cylindrical bottle, take out the elastic filter screen, and then remove the filter bag. If further filtration is required, transfer the sample along with the filter bag into a sand core crucible and perform filtration on a vacuum filtration device according to the specifications in GB / T 2910.1-2009 Quantitative Chemical Analysis of Textiles – Part 1: General Tests. After filtration, place the sand core crucible, sample, and filter bag together in an oven to dry. Record the sample weight after drying. Based on the markings on the filter bag, record the weight before dissolution to ensure quantitative accuracy. Example 2

[0036] like Figure 3 As shown, the bottle wall of the round-bellied bottle 4 is also provided with an air inlet 4.1 with a valve. The air inlet 4.1 is connected to the air pipe 7. The air pipe 7 periodically ventilates the round-bellied bottle 4. The gas forms bubbles in the solution and drives the filter bag 2 to roll, which increases the dissolution speed and prevents the filter bag 2 from getting tangled or stuck during the vibration of the shaker, ensuring that the filter bag 2 moves in the solution.

[0037] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
