Description

Technical Field

[0001] This utility model relates to the field of textile production equipment technology, and more specifically, it relates to a slicing and grading switching valve for a PET intermediate silo. Background Technology

[0002] In the textile industry, PET intermediate storage silos typically refer to intermediate storage devices used to temporarily store PET chips, granules, or fiber materials during the recycling and processing of polyester fibers or textiles. They serve as buffers and stabilize the material flow. The core function of PET intermediate storage silos is to act as a buffer in the production process, connecting upstream processing equipment (such as granulators and washing lines) with downstream processes (such as spinning machines and packaging equipment) to ensure a continuous and stable supply of materials and avoid production efficiency being affected by equipment start-ups or flow fluctuations.

[0003] However, the PET solution in the intermediate PET silo may deteriorate during the spinning process due to thermal degradation, hydrolysis, or oxidation, which can cause impurities to form in the PET solution and make it cloudy, thus leading to a decline in fiber quality. When the PET solution in the intermediate PET silo is found to have deteriorated, it is usually necessary to manually shut down the upstream processing equipment and downstream processes, pour out all the deteriorated PET solution in the intermediate PET silo, and then start production again. This is not only time-consuming and labor-intensive, but also requires staff to constantly observe the PET solution in the intermediate PET silo.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a PET intermediate material silo slice grading switching valve in order to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model embodiment is achieved through the following technical solution: a slicing and grading switching valve for a PET intermediate silo, comprising an intermediate silo body, characterized in that: a conveying pipe is fixedly connected to the lower end of the intermediate silo body, a mounting base is fixedly connected to the bottom of the conveying pipe, a first pipe and a second pipe are respectively connected to the mounting base, a reversing valve is rotatably connected inside the mounting base, a driving device for driving the reversing valve to rotate is provided on one side of the mounting base, a turbidity sensor for detecting the turbidity of the PET solution is provided inside the reversing valve, and the turbidity sensor is electrically connected to the driving device.

[0007] The present invention is further configured such that: the reversing valve is provided with a first through hole and a second through hole, the first through hole is connected to the conveying pipe and is perpendicular to the second through hole, the lower end of the reversing valve is connected to a support column, the mounting base is provided with a mounting groove that rotates with the support column, and a ball bearing is provided between the mounting groove and the support column.

[0008] The present invention is further configured such that: the driving device includes a driving motor fixedly connected to the mounting base, the output end of the driving motor is fixedly connected to a driving gear, and the reversing valve is located outside the first through hole and is fixedly connected to a plurality of teeth arranged in a circumferential array around the first through hole, the teeth meshing with the driving gear.

[0009] The present invention is further configured such that the driving gear is a sector gear with a central angle of 90 degrees.

[0010] The present invention is further configured such that: the reversing valve is slidably connected to an abutment ring at the second through hole, the outer end of the abutment ring is provided with a tapered abutment surface, the abutment surface abuts against the first pipe or the second pipe respectively, and a spring is fixedly connected between the abutment ring and the reversing valve.

[0011] The present invention is further provided that a sealing ring is fixedly connected to the contact surface.

[0012] In summary, this utility model has the following beneficial effects: By installing a reversing valve in the PET intermediate silo, and having a turbidity sensor inside the reversing valve that is electrically connected to the drive unit, when the turbidity sensor detects that the PET solution has become turbid, the drive unit will rotate the reversing valve to discharge the deteriorated PET solution through a second pipe. When the turbidity sensor detects that the PET solution has become clear again, it will rotate the reversing valve to reconnect with the first pipe, thereby transporting the PET solution to the downstream process. Thus, when the PET solution deteriorates, there is no need to shut down the downstream process, and there is no need for staff to constantly observe the PET intermediate silo, which not only saves time and labor but also frees up staff.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] In one possible embodiment, please refer to Figure 1 and Figure 2 As shown, a PET intermediate silo slicing and grading switching valve includes an intermediate silo body 1. A conveying pipe 2 is fixedly connected to the lower end of the intermediate silo body 1. A mounting base 3 is fixedly connected to the bottom of the conveying pipe 2. A first pipe 4 and a second pipe 5 are respectively connected to the mounting base 3. The first pipe 4 is connected to the downstream process. A reversing valve 6 is rotatably connected inside the mounting base 3. During normal operation, the reversing valve 6 is connected to the first pipe 4. The PET in the intermediate silo body 1 is transferred to the reversing valve 6 through the conveying pipe 2, and then transported to the downstream process through the first pipe 4.

[0017] For further details, please refer to Figure 1 and Figure 2 As shown, the reversing valve 6 is provided with a first through hole 601 and a second through hole 602. The first through hole 601 is connected to the conveying pipe 2 and is perpendicular to the second through hole 602. The second through hole 602 is connected to the first pipe 4 or the second pipe 5. The lower end of the reversing valve 6 is connected to a support column 603. The mounting base 3 is provided with a mounting groove 301 that rotates with the support column 603. A ball bearing 9 is provided between the mounting groove 301 and the support column 603. By providing the ball bearing 9, the friction between the support column 603 and the mounting base 3 can be reduced, so that the reversing valve 6 can rotate smoothly.

[0018] For further details, please refer to Figure 1 , Figure 2 and Figure 4As shown, a drive device 7 for rotating the reversing valve 6 is provided on one side of the mounting base 3. A turbidity sensor 8 for detecting the turbidity of the PET solution is installed inside the reversing valve 6. The turbidity sensor 8 is electrically connected to the drive device 7. When the turbidity sensor 8 detects that the PET solution has become turbid, the drive device 7 will drive the reversing valve 6 to rotate, and discharge the deteriorated PET solution through the second pipe 5. When the turbidity sensor 8 detects that the PET solution has become clear again, it will drive the reversing valve 6 to rotate again and reconnect with the first pipe 4, thereby transporting the PET solution to the downstream process. Therefore, when the PET solution deteriorates, there is no need to shut down the downstream process, and there is no need for staff to constantly observe the intermediate PET silo. This not only saves time and labor, but also frees up staff.

[0019] For further details, please refer to Figure 1 , Figure 2 and Figure 4 As shown, the driving device 7 includes a drive motor 701 fixedly connected to the mounting base 3. The output end of the drive motor 701 is fixedly connected to a drive gear 702. The reversing valve 6 is located outside the first perforation 601 and is fixedly connected to multiple teeth 703 arranged in a circumferential array around the first perforation 601. The teeth 703 mesh with the drive gear 702. When the turbidity sensor 8 detects that the PET solution has become turbid, it will issue a command to drive the drive motor 701 to work, thereby causing the drive gear 702 to rotate, which in turn drives the teeth 703 meshing with the drive gear 702 to rotate, and then drives the reversing valve 6 to rotate. The drive gear 702 is a sector gear with a central angle of 90 degrees. When the drive gear 702 rotates one revolution, it drives the reversing valve 6 to rotate one-quarter revolution, so that the second perforation 602 is connected to the second pipe 5, allowing the deteriorated PET solution to be discharged through the second pipe 5.

[0020] For further details, please refer to Figure 2 and Figure 3 As shown, the reversing valve 6 is slidably connected to an abutment ring 10 at the second perforation 602. By setting the abutment ring 10, it can play a conductive role when the second perforation 602 is connected to the first pipe 4 or the second pipe 5, so that the PET solution can flow smoothly into the first pipe 4 or the second pipe 5. The outer end of the abutment ring 10 is provided with a tapered abutment surface 1001, which abuts against the first pipe 4 or the second pipe 5 respectively. A spring 11 is fixedly connected between the abutment ring 10 and the reversing valve 6. When the reversing valve 6 rotates, the tapered surface will abut against the inner wall of the first pipe 4 or the second pipe 5 and slide into the reversing valve 6. When it rotates to connect with the next pipe, the abutment ring 10 will rebound under the action of the spring 11 and abut again. A sealing ring 1002 is fixedly connected to the abutment surface 1001, so as to ensure the sealing between the abutment ring 10 and the first pipe 4 and the second pipe 5, effectively preventing the PET solution from flowing out.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
