Description of the Drawings
[0012] Figure 1 It is a schematic structural diagram of the small chemical fiber slice conveying system of the present utility model. Detailed Embodiments
[0013] The present utility model will be further described in detail below.
[0014] As Figure 1 shown, the present utility model provides a small chemical fiber slice conveying system, including a slice drying tower 1, a conveying tower 2, and a control unit 3.
[0015] The bottom of the slicing drying tower 1 is provided with a discharge port, and the top of the conveying tower 2 is provided with a feed port; a control valve for controlling the feeding is arranged on the conveying pipeline between the discharge port of the slicing drying tower 1 and the feed port of the conveying tower 2 and is connected to the control unit 3; a high-level sensor 4 is arranged at the upper side end of the conveying tower 2 at the high-level warning line, and a low-level sensor 5 is arranged at the lower side end of the conveying tower 2 at the low-level warning line. The high-level sensor 4 and the low-level sensor 5 are respectively connected to the control unit 3 for transmitting the information that the cut materials exceed the high-level warning line and the low-level warning line in the conveying tower 2 to the control unit 3; it also includes a time relay 6 connected to a power supply (not shown in the figure). The time relay 6 is always in the energized state and starts timing once it is powered on. The time reset signal terminal of the time relay 6 is connected to the high-level sensor 4. The time relay 6 is used to receive the signal of the high-level sensor 4 and output a control signal after the set delay time ends. When the signal of the high-level sensor 4 is received again within the delay time, the delay time is re-timed; an alarm 7 is connected to the signal output terminal of the time relay 6 for alarming when receiving the control signal.
[0016] The control unit 3 of this embodiment is connected to a high-level signal lamp (not shown in the figure) for indicating that the cut materials reach the high-level warning line; the control unit 3 is connected to a low-level signal lamp (not shown in the figure) for indicating that the cut materials reach the low-level warning line. When the slices rise to the high-level warning line, the high-level sensor 4 sends a signal to the control unit 3, indicating that the material level is full and the conveying of the slices is stopped. When the slices drop to the low-level warning line, the low-level sensor 5 sends a signal to the control unit 3 for low-level alarm, that is, there is a shortage of materials.
[0017] An angle valve 8 is arranged on the conveying pipeline of this embodiment; the conveying pipeline between the feed port of the angle valve 8 and the discharge port of the slicing drying tower 1 is a slicing feed pipe 9, and the conveying pipeline between the discharge port of the angle valve 8 and the feed port of the conveying tower 2 is a slicing discharge pipe 10. The angle valve 8 is connected to a compressed air pipe 11 for conveying compressed air, which is used to blow the slices into the conveying tower 2; the compressed air pipe 11 is connected to a compressed air source (not shown in the figure). The control valve is an electromagnetic valve 12 arranged on the compressed air pipe 11; the electromagnetic valve 12 is connected to the control unit 3 for controlling the conveying of the slices.
[0018] A pressure gauge 13 for monitoring the pressure of the conveying pipeline to prompt whether the conveying pipeline is blocked is arranged on the conveying pipeline of this embodiment. The pressure gauge 13 is connected to the control unit 3 for transmitting the pressure information to the control unit 3. The control unit 3 is connected to a blockage alarm device for transmitting the conveying pipeline blockage signal converted from the pressure information to the blockage alarm device (not shown in the figure) for alarming. Generally, the pulse pressure during the conveying of the slices is not large, about 0.2 MPa. If the pipeline is blocked, the pressure will increase and an alarm will be triggered.
[0019] Working process: During the process of conveying the chips from the chip drying tower 1 to the conveying tower 2, the high-level sensor 4 and the low-level sensor 5 monitor in real time whether the chips reach the high-level warning line and the low-level warning line, and transmit the information to the control unit 3. The control unit 3 warns whether the warning line is reached through the high-level signal lamp and the low-level signal lamp respectively. During this process, the time relay 6 is always in the powered-on state and in the timing state. Since the timing reset function point of the time relay 6 is connected to the signal point of the high-level sensor 4, during the timing process of the time relay 6, if the set delay time is reached and the time relay 6 does not receive the signal from the high-level sensor 4, the time relay 6 outputs a control signal to the alarm 7 for alarming; on the contrary, if the time relay 6 receives the signal from the high-level sensor 4 within the delay time, the time is reset and the timing is restarted until the signal from the high-level sensor 4 is received again next time, and then the timing is restarted again. Therefore, during the timing process, once the signal from the high-level sensor 4 is not received after reaching the set delay time, the alarm 7 is triggered for alarming; on the contrary, if the signal from the high-level sensor 4 is received within the set delay time, the time relay 6 is triggered to reset and restart the timing. When the alarm 7 gives an alarm, it indicates that there is a problem with the conveying at this time. Compared with the situation where the low-level sensor 5 conveys information to the controller when the chips drop to the low-level warning line, it belongs to an early warning, so that the fault can be checked in time, thus avoiding the spinning tripping accident.
[0020] In actual production, the delay time of the time relay 6 is set according to the time interval from one high-level signal to the next high-level signal. The delay time of the time relay 6 can be set slightly longer than the actual interval.
