Detailed Implementation
[0023] This utility model provides a high-mesh sieve for testing fiber content, such as... Figure 1-5As shown, the device includes a base 101, an output chamber 114 with an opening that runs vertically through the base 101, a detachable screen 106 mounted at the top of the output chamber 114, a screening chamber 110 with an outward opening inside the screen 106, a high-mesh screen 117 fixedly mounted at the bottom of the screening chamber 110, two splitting bases 109 fixedly mounted on the inner wall of the screening chamber 110, the splitting bases 109 on both sides being symmetrically positioned, a mounting connecting plate 108 fixedly mounted at the top of the splitting base 109, and a detachable low-mesh screen 111 mounted between the mounting connecting plates 108 on both sides.
[0024] It should be further explained that the high-mesh screen 117 is made of 304 stainless steel frame and 304 stainless steel mesh, while the low-mesh screen 111 is made of 304 stainless steel frame and 304 stainless steel mesh. The high-mesh screen 117 has a higher mesh number than the low-mesh screen 111. The high-mesh screen 117 finely separates the target fibers, while the low-mesh screen 111 quickly separates impurities or large fiber particles.
[0025] Furthermore, the top of the base 101 is provided with two outward-facing mounting slots 113, and the mounting slots 113 on both sides are symmetrically arranged. The mounting slots 113 are provided with support rods 105 that can be raised and lowered.
[0026] Furthermore, support plates 112 are fixedly provided on both sides of the top end of the outer end face of the screen 106. The support plates 112 on both sides are symmetrically arranged, and the support plates 112 on both sides are fixedly connected to the top end of the support rod 105.
[0027] Furthermore, the base 101 has two detection slots 104 with openings on both sides of its outer end face that communicate with the output cavity tube 114, and the detection slots 104 on both sides are symmetrically arranged.
[0028] Furthermore, a protective plate 115 is fixedly installed inside the detection slot 104, and an image monitoring and acquisition device 116 is fixedly installed at the top of the protective plate 115 and inside the output cavity tube 114. The image monitoring and acquisition device 116 is angled towards the high mesh screen 117.
[0029] It should be further explained that the image monitoring and acquisition device 116 uses an integrated CMOS line scan camera to monitor the screen damage and blockage in real time and provide early warning of maintenance needs.
[0030] Furthermore, a detection processor 107 is installed inside the protection board 115, and a data cable 103 is connected to the back of the detection processor 107.
[0031] Furthermore, a signal transmitter 102 is fixedly installed on the outer end face of the base 101 and on one side of the detection groove 104, and the other end of the data connection line 103 is connected to the signal transmitter 102 for data transmission.
[0032] It should be further noted that the signal transmitter 102 connects to the control terminal via LoRa communication for data signal connection.
[0033] When using this solution, first move the screen 106 to the working position, and install the high-mesh screen 117 for fine screening and the low-mesh screen 111 for coarse screening into the screen 106 according to the mesh number gradient. Fix the positions on both sides by mounting the bracket connecting plate 108 to ensure that the screen layering order is as follows: the upper low-mesh screen 111 quickly separates impurities or large fiber particles, and the lower high-mesh screen 117 finely separates the target fibers.
[0034] Then, the outlet of the screening chamber 110 in the base 101 is connected to the output port of the fiber sample to be tested. After the support plates 112 on both sides of the screen 106 are fixedly connected to the support rod 105, the support rod 105 is installed and inserted into the mounting groove 113. At this time, a part of the screen 106 enters the output chamber tube 114 of the base 101.
[0035] Subsequently, the fiber sample to be tested is slowly poured into the interface sieving chamber 110. The fiber first contacts the upper coarse screen and low-number screen 111, and the fiber forms a uniformly distributed layer on the screen surface. Large particles or fibers are quickly separated to the collection area below the low-number screen 111. Fine sieving and monitoring are performed on fibers that do not pass through the coarse screen. Fibers that do not pass through the coarse screen continue to fall to the high-mesh screen 117. Fibers of a specific diameter or length are intercepted, and the remaining fine impurities enter the bottom of the base 101 through the screen holes and are subsequently output.
[0036] During this process, the image monitoring and acquisition device 116 scans the surface of the high-mesh screen 117 in real time, identifies the clogging area of the screen holes through image processing algorithms, such as abnormal local gray values, or identifies screen damage, and transmits the identification data to the signal transmitter 102 through the data connection 103. After the signal transmitter 102 transmits the signal to the data terminal, it is used by the staff for data monitoring and analysis. When abnormal problems are detected on the surface of the high-mesh screen 117, the staff can be notified in time to replace the low-mesh screen 111 and the high-mesh screen 117 in the screen maker 106. It can also remind the staff to carry out cleaning work in a timely manner. Through the integration of the double-layer screen cascade design and the intelligent monitoring system, the fiber separation efficiency is improved. The screen frame is made of 304 stainless steel and the middle screen is made of polyvinyl chloride fabric, which improves the durability of the screen and extends its service life.
