Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric detection, in particular to a non-woven fabric scatterability test device. Background Art

[0002] According to the standard for fabric flushability testing, the shaking tank decomposition test requires multiple and complex steps. Existing flushability test devices are mostly split, with a shaking tank and a flushing tank. This requires multiple moves of the equipment and handling of the test water, resulting in numerous test steps and extensive handling, making it difficult for a single person to complete the test independently. Traditional split-type test devices require the shaking tank to be moved to a sink after each shake. The shaking tank is a 43cm x 33cm x 30cm box filled with 2L of water. This means that it's not guaranteed that every inspector can remove the tank and transport it to the sink. Furthermore, traditional retrieval methods cannot fully retrieve the samples from the shaking tank. Water flowing from the shaking tank into the sewer can leave a large amount of water near the sink, compromising safety during the test due to water stains. The traditional method of manually removing unflushed samples from the sieve plate also results in variability due to human error, resulting in low test accuracy. Utility Model Content

[0030] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will be more clearly described according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in exact proportions. They are only used to facilitate and clearly illustrate the purpose of the embodiments of the present invention.

[0031] like Figure 1As shown, this embodiment provides a non-woven fabric dispersibility test equipment, including a vibration table 1, a shaking water tank 2, a liquid storage tank 3 and a sieve plate 4; the shaking water tank 2 is arranged on the vibration end of the vibration table 1, the liquid storage tank 3 is arranged on one side of the vibration table 1, the upper end of the shaking water tank 2 is provided with a feeding port 21, the upper end of the liquid storage tank 3 is open, the sieve plate 4 is arranged at the open end of the liquid storage tank 3, the bottom of the shaking water tank 2 close to the liquid storage tank 3 is provided with a first drain port 22 located above the sieve plate 4, the lower end of the liquid storage tank 3 is provided with a second drain port 31, the first drain port 22 is provided with a first opening and closing member 23, and the second drain port 31 is provided with a second opening and closing member 32. By directly installing the shaking water tank on the vibration table, and the liquid storage tank is arranged next to the vibration table, and the first drainage port of the shaking water tank is located above the liquid storage tank, during the test, the first opening and closing parts can be closed, and water can be added to the shaking water tank, and then the fabric sample is placed in the shaking water tank, and the vibration table is started to drive the shaking water tank to shake. After the shaking time of the shaking water tank reaches the set time, the sieve plate is installed on the upper end of the liquid storage tank, and the first opening and closing part is opened. At this time, the fabric sample is discharged onto the sieve plate through the first drainage port and filtered by the sieve plate. After the fabric is flushed, the fine fragments enter the liquid storage tank, while the large fragments remain on the sieve plate. At this time, the fabric fragments on the sieve plate and the liquid storage tank can be collected and weighed (drying treatment is required before weighing).

[0032] The vibration table described in this embodiment can be an electric vibration table, whose vibration frequency and vibration duration can be adjusted. The vibration table can be similar to the structure disclosed in document number CN111964858B "A Vibration Table" or document number CN109049272B "Vibration Table". In this case, a shell can be added to the outside of the vibration table for aesthetic treatment.

[0033] See Figure 1 As shown, in the above technical solution, there are multiple shaking water tanks 2, and the multiple shaking water tanks 2 are all arranged on the vibrating end of the vibration table 1. In this way, multiple fabric samples can be shaken at the same time, but the fabric fragments can be collected independently, which can improve the test efficiency.

[0034] like Figure 3As shown, the vibration table in this embodiment is rectangular, and multiple shaking water tanks 2 are arranged side by side on the vibration table. Preferably, there are three shaking water tanks, and the shaking water tanks are fixedly installed on the vibration end of the vibration table. At this time, when the vibration table is running, the three shaking water tanks 2 vibrate synchronously, and the side of the shaking water tank provided with the first liquid discharge port extends to the corresponding side of the vibration table. The liquid storage tank is also rectangular, and its two ends can be flush with the two ends of the vibration table, and multiple first liquid discharge ports are located directly above the liquid storage tank.

[0035] like Figure 2 As shown, the above technical solution also includes a shower head 5, which is arranged on the side wall of the vibration table 1, and its water inlet end is connected to the municipal water supply pipe. The shower head 5 is used to sprinkle water on the sieve plate 4 or add water to the shaking water tank 2, so that after the sieve plate filters the liquid discharged from the first drain port, it can also use the shower head to spray on the sieve plate to further flush the small fabric fragments to the bottom of the sieve plate, and the shower head can also be used to add water to the shaking water tank, which makes it more convenient to use water for the entire non-woven fabric flushability test equipment.

[0036] The shower head 5 in the above technical solution includes a water inlet valve 51, a shower hose 52, a shower head 53 and a wall mount 54. The water inlet valve 51 and the wall mount 54 are both arranged on the side wall of the vibration table 1. One end of the shower hose 52 is connected to the municipal water supply pipe through the water inlet valve 51, and the shower head 53 is arranged at the other end of the shower hose 52. The shower head 53 is placed on the wall mount 54. Its structure is simple, so that the shower head can be arranged on the side wall of the vibration table in an orderly manner (the water inlet valve can be a flow regulating valve, which can conveniently adjust the water flow of the shower head).

[0037] Specifically, the connection point between the water inlet valve and the municipal water supply pipe can be led to the faucet of the laboratory through a hose and connected to one of the faucets.

[0038] In the above technical solution, the sieve plate 4 is detachably mounted on the opening at the upper end of the liquid storage tank 3, so that the sieve plate can be conveniently removed from the opening at the upper end of the liquid storage tank, so that the entire sieve plate can be placed in an oven for drying.

[0039] like Figure 4 As shown, in the above technical solution, the edge of the sieve plate 4 is provided with a edging strip 41, the slot of the liquid storage tank 3 is expanded to form a supporting opening 33, and the sieve plate 4 is supported at the supporting opening 33 at the upper end of the liquid storage tank 3, or as shown in FIG. Figure 5As shown, a plug-in slot 34 is provided at the notch of the liquid storage tank 3 (plug-in slots are provided on both sides of the long side of the liquid storage tank for the sieve plate to be inserted), and the sieve plate 4 is inserted into the plug-in slot 34 to cover the open end of the liquid storage tank 3, so that the structural strength of the sieve plate is high and the durability is good.

[0040] In the above technical solution, the aperture of the sieve plate 4 is 12.5 mm, and the opening rate of the sieve plate 4 is 70-90%. The structure is simple and meets the requirements of the corresponding test standards.

[0041] In the above technical solution, the inner bottom walls of the shaking water tank 2 and the liquid storage tank 3 are both inclined surfaces, and the first drain port 22 is located at the lowest point of the horizontal height of the inner bottom wall of the shaking water tank 2, and the second drain port 31 is located at the lowest point of the horizontal height of the inner bottom wall of the liquid storage tank 3. This makes it more convenient to drain the shaking water tank and the liquid storage tank, and debris is not easily left in the shaking water tank and the liquid storage tank.

[0042] In the above technical solution, the first drain port 22 is horizontally arranged at the lower end of the shaking water tank 2 close to the liquid storage tank 3, and the first opening and closing part 23 is a gate valve, which has a simple structure and good drainage effect, especially the first opening and closing part will not affect the discharge of fabric fragments when it is in the open state.

[0043] Specifically, such as Figure 1 As shown, the first opening and closing member 23 includes an insert plate 231 and two slots 232. The two slots are arranged on both sides of the first drainage port, and the slots of the two slots are close to each other, and the upper ends of the two slots are open, but the lower ends are blocked. A flexible pad 233 (which can be a rubber pad, a silicone pad or a latex pad) is provided on one side of the insert plate 231. The insert plate is vertically inserted downward into the two slots through the upper ends of the two slots, and the side provided with the flexible pad faces the first drainage port, and completely covers and blocks the first drainage port. When the first drainage port needs to be opened, it is only necessary to pull the insert plate upward away from the two slots. Since the flexible pad has a certain expansion and contraction property, when the insert plate is between the two slots, the flexible pad is squeezed, so it can well seal and cover the first drainage port.

[0044] like Figure 1 As shown, in the above technical solution, the second drain port 31 is a tubular port, and an external thread is provided on its outer wall. The second opening and closing member 32 is a groove-shaped cover, and an internal thread is provided on the inner wall of the second opening and closing member 32. The second opening and closing member 32 is threadedly connected to the second drain port 31, so that the second opening and closing member can be directly unscrewed from the second drain port, which will not affect the discharge of fabric fragments.

[0045] In this embodiment, after the second opening and closing member is opened, the water bucket can be used to collect the waste liquid containing fabric fragments discharged from the liquid storage tank (not directly discharged into the sewer to avoid clogging of the pipe by fabric fragments).

[0046] The nonwoven fabric dispersibility test equipment provided in this embodiment operates as follows:

[0047] Step 1: Dry the sieve plate to a constant weight of m2;

[0048] Step 2: Close the first opening and closing parts and the second opening and closing parts, install the sieve plate on the upper end of the liquid storage tank, add 2L of water to each shaking water tank, control the water temperature at 22±3℃, weigh the fabric sample as m1, and then place the fabric sample in the shaking water tank, start the vibration table, and turn off the vibration table after the vibration table runs for the set time.

[0049] Step 3: Open the first opening and closing part to drain the liquid in the shaking water tank onto the sieve plate. After draining, hold the shower head (the shower head is 10-15 cm above the sieve plate) and spray the fabric fragments on the sieve plate (the spray flow rate is 4L / min) for 2 minutes. Then remove the sieve plate and transfer it to the oven to dry until the constant weight is m3;

[0050] Step 4: Clean the sieve plate and repeat steps 1-3 to process the remaining sample discharge in the shaking water tank.

[0051] The decomposition rate of the fabric sample in each shaking water tank is (m3-m2) / m1.

[0052] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
