Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of chemical fiber separation, especially relates to a fiber separator facilitating cleaning of cotton bundles. BACKGROUND

[0002] In the process of vortex spinning, the cleanliness of raw cotton is crucial. To ensure the quality of subsequent yarn products and reduce defects and impurities, back air ducts are added in the pre-spinning process of cleaning and carding. These back air ducts can remove dust, fine particles, and cotton blocks from the raw cotton. Subsequently, the back air containing impurities and unqualified cotton is sent to a separator for separation of impurities, cotton, and air. After separation, the back air is sent to a dust removal chamber for further dust removal, and the separated cotton fibers can be reused in the spinning production line.

[0003] However, the current fiber separator generally uses a spiral compression method, such as the existing technical solutions disclosed in Chinese patent documents CN217298122U, CN203700609U, and CN103696047A. The spiral compression method has obvious defects. Specifically:

[0004] 1) During the rotation of the rotating blade, spiral compression can easily cause cotton bundles to be stuck. Once the cotton bundles are stuck, the device will fail to perform normal impurity separation work. Meanwhile, cotton bundle sticking can also increase the frequency of motor burnout. Frequent motor burnout not only affects production progress but also greatly reduces the service life of the motor, increasing the production cost and equipment maintenance cost of the enterprise.

[0005] 2) There are also significant safety hazards when performing unblocking operations after the cotton bundles are stuck. During the unblocking process, improper operation may cause contact with high-speed rotating parts or loose parts, which can easily cause personal injury accidents. Moreover, unblocking operations usually require certain skills and experience, and improper operation may further damage the equipment and even cause more serious safety problems. In addition, frequent unblocking work will also occupy a lot of production time, reducing production efficiency. To ensure the safety of the unblocking process, the enterprise may need to invest more manpower and resources in safety protection and supervision, which also increases the operating cost of the enterprise.

The lower separation part 2 is cylindrical, and the side of the lower separation part 2 is connected with the dust exhaust pipe 5, which is connected with the dust removal chamber. The bottom of the lower separation part 2 is provided with a cotton discharge bin 6, which has a reasonable structure and can smoothly discharge cotton fibers.

[0037] The conical filter cartridge 7 is inverted and fixedly installed in the inside of the lower separation part 2, and the top and bottom of the conical filter cartridge 7 are open. The cylinder wall of the conical filter cartridge 7 is provided with filter holes 16. The top edge of the conical filter cartridge 7 is closely arranged with the inner side wall of the sealed cylinder, to ensure that no material leaks from the gap. The bottom of the conical filter cartridge 7 is connected with the cotton discharge bin 6 at the bottom of the lower separation part 2, so that the separated cotton fibers can smoothly enter the cotton discharge bin 6.

[0038] The spiral pressing mechanism includes motor drive unit 8, transmission shaft 9 and conical spiral blade 10. The transmission shaft 9 is coaxially arranged in the inside of the sealed cylinder, including bearing assembly 9.2 and shaft 9.1, and the shaft 9.1 penetrates the top of the sealed cylinder and is rotatably connected with the top of the sealed cylinder through the bearing assembly 9.2. The motor drive unit 8 is arranged at the top of the sealed cylinder and fixedly connected with the shaft 9.1 of the transmission shaft 9 to establish power transmission. In this structure, the transmission shaft 9 is accurately installed at the center position of the sealed cylinder, to ensure stable operation. The conical spiral blade 10 is correspondingly arranged in the inside of the conical filter cartridge 7 and coaxially fixedly connected with the transmission shaft 9, and its size is matched with the size of the conical filter cartridge 7.

[0042] Generally, the equipment can be automatically unclogged, and directly enters normal operation after unclogging, but when the cotton fibers in the conical filter cylinder 7 are too much and there is not enough space to support the automatic unclogging of the equipment, the cotton fibers pushed up to the feeding pipeline 4 can be taken out through the material taking window 11 to make more space for unclogging. The material taking window 11 is arranged on the feeding pipeline 4 and is outside the sealed cylinder, which ensures the safety of the material taking operation.

[0048] Embodiment 5

[0049] The embodiment discloses a fiber separator facilitating cleaning of cotton bundles, and as a preferred embodiment of the application, the inside of the cotton discharge bin 6 is provided with a movable opening and closing door 13 which is hinged to the inner wall of the cotton discharge bin 6 through a spring member 14 and is opened and closed based on the weight of cotton fibers. More specifically, the movable opening and closing door 13 is provided with an elastic sealing member at the contact surface with the cotton discharge bin 6, so as to prevent dust from flowing out of the cotton discharge bin 6 when no cotton fibers are accumulated above the movable opening and closing door 13. Further, a locking member can be arranged on the movable opening and closing door 13, and after the movable opening and closing door 13 is fixed through the locking member, a non-blocking cotton discharge channel is formed, and the cotton fibers pressed and falling downward can directly fall from the cotton discharge bin 6, so that the cotton discharge speed is improved.

[0050] The motor device 8.1 is connected with the three-phase power supply main circuit and the three-phase power supply source; in the three-phase power supply main circuit, a circuit breaker Q1 and a thermal protector FR are sequentially connected between a three-phase power supply source end and the motor device 8.1 end; between the thermal protector FR and the motor device 8.1, a forward rotation power supply branch is arranged based on a forward rotation contactor KM1, and a reverse rotation power supply branch is arranged based on a reverse rotation contactor KM2.

[0051] The input end of the forward rotation control circuit is connected with the C-phase live wire (L3) of the three-phase power supply source through an emergency stop switch S1, and the output end is connected with the neutral line N of the three-phase power supply source, and is used for controlling the forward rotation contactor KM1 to be turned on or turned off.

[0052] The input end of the reverse rotation control circuit is connected with the C-phase live wire (L3) of the three-phase power supply source through the emergency stop switch S1, and the output end is connected with the neutral line N of the three-phase power supply source, and is used for controlling the forward rotation contactor KM2 to be turned on or turned off.

[0053] The working principle of the technical solution is as follows:

[0054] The three-phase power supply source provides power for the entire motor control circuit system. The circuit breaker Q1 mainly plays a role in cutting off the circuit, and can timely disconnect the circuit when overloading, short circuit and other faults occur in the circuit, so as to protect the safety of the equipment. The thermal protector FR is used for monitoring the current of the motor device 8.1, and automatically cuts off the circuit when the motor overloads and generates heat, so as to prevent the motor from being damaged.

[0055] When the motor device 8.1 is to be forward rotated, the forward rotation control circuit works to achieve by controlling the on-off of the forward rotation contactor KM1. The input end of the forward rotation control circuit is connected with the C-phase live wire (L3) of the three-phase incoming power supply through the emergency stop switch S1, and the output end is connected with the neutral line N. When the forward rotation control circuit makes the forward rotation contactor KM1 closed, in the three-phase power supply main circuit, the forward rotation power supply branch is formed from the three-phase incoming power supply through the circuit breaker Q1, the thermal protector FR and the forward rotation contactor KM1, and the motor device 8.1 is powered to be forward rotated.

[0056] When the motor device 8.1 is normally operated, the electric energy is mainly converted into mechanical energy. When the device is in the situation of cotton jam, the motor device 8.1 cannot rotate, and thus cannot output mechanical energy. According to the law of conservation of energy, at this time, the electric energy will be more converted into heat energy, which will cause the current in the three-phase power supply main circuit to increase sharply. The thermal protector FR monitors the overload current, and the forward rotation control circuit controls the forward rotation contactor KM1 to be opened based on the overload current. At the same time, the circuit breaker Q1 trips based on the linkage with the thermal protector FR, so that the forward rotation power supply branch of the motor device 8.1 is disconnected.

[0057] When the motor device 8.1 is to be reversed, the circuit breaker Q1 is first reset, and then the reverse rotation control circuit is started to work to control the on-off of the reverse rotation contactor KM2. When the reverse rotation control circuit makes the reverse rotation contactor KM2 closed, in the three-phase power supply main circuit, the reverse rotation power supply branch is formed from the three-phase incoming power supply through the circuit breaker Q1, the thermal protector FR and the reverse rotation contactor KM2, and the motor device 8.1 is powered to be reversed. The emergency stop switch S1 can cut off the power supply of the control circuit in an emergency to stop the operation of the motor device 8.1.

[0058] Embodiment 6

[0059] As a preferred embodiment of the present application, the motor control circuit system further comprises an alarm circuit based on embodiment 5. The alarm circuit comprises a trigger switch and an audible and visual alarm connected in sequence. The input end of the trigger switch is connected with the C-phase live wire of the three-phase incoming power supply, and the output end of the audible and visual alarm is connected with the neutral line N of the three-phase incoming power supply. The trigger switch is a normally open contact switch Q11 (corresponding to the normally closed contact 21 and the normally closed contact 22 in the circuit breaker Q1). Figure 3

[0060] ​In normal circumstances, the circuit breaker Q1 is in the closed state, and the normally open contact switch Q11 (trigger switch) inside it is open. When the circuit is overloaded, short-circuited, or other faults occur, the circuit breaker Q1 will automatically open, and at this time the normally open contact switch Q11 (trigger switch) inside it will close. Because the input end of the trigger switch is connected with the C-phase live wire (L3) of the three-phase incoming power supply, and the output end is connected with the sound and light alarm, and the output end of the sound and light alarm is connected with the neutral line N of the three-phase incoming power supply, once the trigger switch is closed, the alarm circuit will be turned on, and after the alarm circuit is turned on, the sound and light alarm will be powered on and work, and a sound and light alarm signal will be sent to remind the staff that the circuit has a problem.

[0061] In this case, if the staff wants to turn off the sound and light alarm, the trigger switch needs to be disconnected, which will reset the circuit breaker Q1 and facilitate the reverse control operation of the motor device 8.1.

[0062] Embodiment 7

[0063] This embodiment discloses a fiber separator for conveniently cleaning cotton bundles, which is a preferred embodiment of the present application, i.e. based on embodiment 5 or 6, the forward control circuit includes a start switch QA, a contactor KM2 closed point, a time relay KT, and a contactor KM1 coil connected in sequence from the output end of the emergency stop switch S1; the input end of the relay KT coil is connected between the contactor KM2 closed point and the time relay KT; the output ends of the contactor KM1 coil and the relay KT coil are connected to the neutral line N of the three-phase incoming power supply.

[0064] When the emergency stop switch S1 is pressed, the circuit is in an operable state, and then the start switch QA is pressed, and the circuit starts to work. After the start switch QA is closed, the current passes through the closed point of the contactor KM2. At this time, it is the forward control circuit, and the reverse contactor KM2 is in an inoperative state, and its closed point (contactor KM2 closed point) is closed, so the current can pass through smoothly.

[0065] After the current passes through the closed point of the contactor KM2, it is divided into two paths. One path of the current enters the relay KT coil, and after the relay KT coil is powered on, the time relay KT is closed; after the time relay KT is closed, the other path of the current continues to pass through the time relay KT, and then reaches the contactor KM1 coil. When the KM1 coil is powered on, the forward contactor KM1 is closed to make the forward conduction branch of the three-phase power supply main circuit conductive, and the motor device 8.1 starts to rotate forward.

[0066] Based on the above positive rotation control loop structure, the motor device 8.1 operating current upper limit can be set to 2A. When the conical spiral blade 10 is stuck by the cotton fiber, the motor device 8.1 is stuck, so that the overload current exceeding the set value 2A appears in the positive rotation power supply branch. The thermal protector FR can detect the overload current signal and transmit it to the thermal protection switch in the motor device 8.1 (also called motor overload protection. The thermal protection switch is generally installed inside the motor or close to the motor shell. Such a position facilitates its direct sensing of the working temperature and current of the motor. Because the current overload in the motor generates too much heat, the thermal protection switch can quickly respond. If it is outside the motor, it is also in a position that can effectively transfer the heat of the motor, so as to accurately monitor the overheating condition of the motor and timely play a protection role). The thermal protection switch converts electrical energy into heat energy, and the bimetallic strip in the thermal protection switch shrinks to trigger the tripping mechanism of the reverse contactor KM2 to disconnect, that is, the closed point of the contactor KM2 is disconnected, further disconnecting the positive rotation control loop, the contactor KM1 coil loses power, and the positive rotation contactor KM1 is disconnected to achieve the purpose of stopping the motor device 8.1.

[0067] In this technical solution, the time relay can be set to start for 2 minutes and stop for 5 minutes of gap operation. In this process, the relay KT coil is turned on for 2 minutes and turned off for 5 minutes. When the relay KT coil is powered on, the time relay KT is closed; when the relay KT coil loses power, the time relay KT is opened. Such a setting has the following advantages: on the one hand, it can save electricity by reducing the running time of the motor device 8.1 through intermittent operation, thereby reducing electricity consumption. On the other hand, it can reduce the probability of the pressure feeder impeller turning the cotton returned by the return air pipe into a cotton bundle because intermittent operation avoids continuous work of the impeller, reduces excessive carding and extrusion of the returned cotton, and thus reduces the possibility of the cotton becoming a cotton bundle.

[0068] Embodiment 8

[0069] This embodiment discloses a fiber separator that facilitates cleaning of cotton bundles, which is a preferred embodiment of the present application, i.e., based on embodiments 5, 6 or 7, the reverse control loop includes a contactor KM1 closed point, a jog button SB and a contactor KM2 coil connected in sequence.

[0070] Under normal circumstances, when the motor does not need to be reversed, the contactor KM1 closed point is closed. When the jog button SB is pressed, the circuit is turned on, and the current flows from the contactor KM1 closed point to the contactor KM2 coil through the jog button SB. After the contactor KM2 coil is powered on, the reverse contactor KM2 will be closed.

[0071] In the three-phase power supply main circuit, a reverse power supply branch is formed through the circuit breaker Q1, thermal protector FR and reverse contactor KM2, and the motor device 8.1 starts to reverse.

[0072] After the jog button SB is released, the contactor KM2 coil loses power, the reverse contactor KM2 is opened, and the motor device 8.1 stops reversing. The contactor KM1 is closed to ensure that the reverse control circuit is not mistakenly triggered when the forward control circuit is working (i.e., the forward contactor KM1 is closed), ensuring the normal forward running state of the motor device 8.1.
