Description

Technical Field

[0001] The present invention relates to the technical field of recycled plastic particle separation, and in particular to a particle separation device and a separation early warning method thereof. Background Art

[0002] Recycled plastic pellets are made from waste plastics. Recycled plastic pellets refer to pellets made from discarded plastic products. Recycled plastic pellets are mainly graded based on the different raw materials used and the characteristics of the processed plastic pellets. They are generally divided into first, second, and third grade materials. First grade materials refer to the raw materials used for the unused scraps, or so-called scraps. Some are nozzle materials, rubber head materials, etc., and the quality is relatively good. They are small scraps left over from the processing of new materials, or raw materials of poor quality. The pellets processed from these raw materials have good transparency and their quality can be compared with new materials. Therefore, they are first-grade or special-grade materials. Second-grade materials refer to the raw materials that have been used once, except for high-pressure granulation. Most of the imported large pieces are used in high-pressure granulation. If the imported large pieces are industrial films, they are not exposed to wind and sun, so their quality is also very good. The transparency of the processed pellets is good. At this time, it should also be judged based on the brightness of the pellets and whether the surface is rough. Third-grade materials refer to the raw materials that have been used twice or more. The pellets processed are not very elastic, toughness, etc.

[0014] In a second aspect, an embodiment of the present application provides an early warning method for a particle separation device, and the specific steps are as follows:

[0015] Step S1. Obtain the screening injection flow of the plastic particles to be screened, and input the screening injection flow into the inclination model so that the inclination model outputs a first inclination instruction, wherein the first inclination instruction is used to control the extension and retraction of the telescopic rod of the supporting assembly to adjust the angle of the angle tray above it. The change in the angle of the angle tray will change the angle of the supporting assembly above it, thereby making the entire cabinet reach the inclined position corresponding to the first inclination angle. The inclination model is a neural network model trained based on experimental data corresponding to historical inclination angles and screening injection flow rates as training data, and is used to determine the optimal filtration angle based on the screening injection flow rate, so that each screening layer can accumulate more screening particles while ensuring the basic injection flow rate. The filtration angle is used to adjust the distribution form of the screened objects in the corresponding screening layer;

[0016] S2. Determine the base power of the drive motor based on the screening injection flow rate, determine the compensation power of the drive motor based on the first inclination angle, and obtain the actual power of the drive motor based on the base power and the compensation power, wherein the base power is the power corresponding to the screening injection flow rate when the storage bin is in a horizontal state, and the compensation power is the additional power consumption corresponding to the resistance caused by the first inclination angle. The actual power is the sum of the base power and the compensation power;

[0017] S3. Placing the plastic particles to be separated above the cabinet and pouring them at a constant flow rate according to the screening injection flow rate. Simultaneously, the drive motor is activated based on the actual power to drive the drive wheel to rotate. The rotation of the drive wheel drives the connecting rod to pull the connecting end block to move. The movement of the connecting end block will drive the cabinet to move along the moving direction of the top edge bar and the guide groove, thereby causing the cabinet at the first inclination angle to slide back and forth at a preset sliding frequency. During this period, an acceleration sensor located at the bottom of the cabinet is used to continuously obtain a sliding waveform of the cabinet and intercept the trough image parameters of the sliding waveform. The trough image parameters of the sliding waveform show a waveform blunting trend with the accumulation of screened material on each layer.

[0018] S4. Calculating, based on the trough image parameters within the first historical time period, a degree of passivation corresponding to the trough image parameters after the first period of time using a Kalman filter algorithm, and recording this as a first predicted passivation value. If the first predicted passivation value is less than a minimum passivation threshold, performing a tilt angle adjustment operation, wherein the tilt angle adjustment operation comprises adjusting the tilt angle of the cabinet multiple times using the telescopic rod to reduce the vertical tilt angle of the cabinet until the corresponding degree of passivation calculated based on the trough image parameters after the multiple adjustments using the Kalman filter algorithm exceeds the minimum passivation threshold.

[0019] S5. When the inclination angle after multiple adjustments is less than the first inclination angle, a first early warning instruction is sent to the operation terminal. The first early warning instruction is used to notify the operator to stop the operation of the plastic particle dumping mechanism, and then stop the plastic particle dumping operation. At the same time, the vertical inclination angle of the cabinet is adjusted to 0° through the telescopic rod. At this time, the guide groove is in a horizontal state, and the operation of the entire particle separation device is stopped after a first time period.

[0020] The working principle and beneficial effects of the present invention are:

[0021] 1. In the present invention, multiple separation boxes are used in conjunction with the filter screens inside the separation boxes to achieve the technical effect of particle classification. The size of the particles filtered by the filter screens inside the separation boxes can be adjusted as needed. Moreover, during filtering, the power supply to the drive motor can be interrupted and the separation box containing particles of the required particle size can be pulled out from the cabinet. This feature allows the process to be interrupted and the plastic particles to be flexibly removed. The removal operation is relatively simple. The structure of the separation box and the cabinet is coordinated to have high structural reliability. The frame structure formed by the support shell, the first reinforcement bar and the second reinforcement bar has high structural strength.

[0022] The driving motor rotates the driving wheel, and the driving wheel rotates to drive the connecting rod to move the first axis, and the connecting rod moves the pulling rod to drive the connecting end block to slide along the movement direction of the guide groove. The cabinet is shaken by the reciprocating motion of the cabinet, driving the separation box and the plastic particles inside it to continuously contact the filter screen below it to complete the classification of the plastic particles.

[0041] Example 2

[0042] The early warning method is used for a particle separation device, and the specific steps are as follows:

[0043] Step S1. Obtain the screening injection flow of the plastic particles to be screened, and input the screening injection flow into the inclination model so that the inclination model outputs a first inclination instruction, wherein the first inclination instruction is used to control the extension and retraction of the telescopic rod 27 of the supporting assembly 200 to adjust the angle of the angle tray 22 above it. The change in the angle of the angle tray 22 will change the angle of the supporting assembly 200 above it, thereby causing the entire cabinet 21 to reach the inclined position corresponding to the first inclination angle. The inclination model is a neural network model trained using experimental data corresponding to historical inclinations and screening injection flows as training data, and is used to determine the optimal filtration angle according to the screening injection flow, so that each screening layer can accumulate more screening particles while ensuring the basic injection flow. The filtration angle is used to adjust the distribution form of the screened objects in the corresponding screening layer;

[0044] S2. Determine the base power of the drive motor 9 based on the screening injection flow rate, determine the compensation power of the drive motor 9 based on the first inclination angle, and obtain the actual power of the drive motor 9 based on the base power and the compensation power. The base power is the power corresponding to the screening injection flow rate when the storage bin 2 is in a horizontal state, and the compensation power is the additional power consumption corresponding to the resistance caused by the first inclination angle. The actual power is the superposition of the base power and the compensation power.

[0045] S3. Place the plastic particles to be separated above the cabinet 21 and pour them at a constant flow rate according to the screening injection flow rate. At the same time, start the drive motor 9 based on the actual power to drive the drive wheel 14 to rotate. The rotation of the drive wheel 14 drives the connecting rod 10 to pull the connecting end block 11 to move. The movement of the connecting end block 11 will drive the cabinet 21 to move along the moving direction of the top edge strip 104 and the guide groove 17, thereby making the cabinet 21 at the first inclination angle slide back and forth according to the preset sliding frequency. During this period, the sliding waveform of the cabinet 21 is continuously obtained by the acceleration sensor provided at the bottom of the cabinet 21, and the trough image parameters of the sliding waveform are intercepted. The trough image parameters of the sliding waveform show a waveform blunting trend with the accumulation of the screened material of each layer;

[0046] S4. Calculating, based on the trough image parameters in the first historical time period, a degree of passivation corresponding to the trough image parameters after the first period of time using a Kalman filter algorithm, and recording this as a first predicted passivation value. If the first predicted passivation value is less than a minimum passivation threshold, performing a tilt angle adjustment operation, wherein the tilt angle adjustment operation comprises adjusting the tilt angle of the cabinet 21 multiple times using the telescopic rod 27 to reduce the vertical tilt angle of the cabinet 21 until the corresponding degree of passivation calculated based on the trough image parameters after the multiple adjustments using the Kalman filter algorithm is greater than the minimum passivation threshold.

[0047] S5. When the inclination angle after multiple adjustments is less than the first inclination angle, a first early warning instruction is sent to the operation terminal. The first early warning instruction is used to notify the operator to stop the operation of the plastic particle dumping mechanism, and then stop the plastic particle dumping operation. At the same time, the vertical inclination angle of the cabinet 21 is adjusted to 0° through the telescopic rod 27. At this time, the guide groove 17 is in a horizontal state, and the operation of the entire particle separation device is stopped after a first time period.

[0048] In addition, in this embodiment, the plastic particles to be separated are placed inside the separation box 19 above the cabinet 21, and the drive motor 9 is started to drive the drive wheel 14 to rotate. The rotation of the drive wheel 14 will pull the rod shaft 12 to drive the connecting rod 10 to rotate. The rotation of the connecting rod 10 will pull the connecting end block 11 and the cabinet 21 connected thereto through the rod shaft 13 to move. The cabinet 21 will move along the axial direction of the guide groove 17. The continuous reciprocating motion of the cabinet 21 allows the plastic particles inside the separation box 19 to continuously contact the filter screen 20 on the bottom surface of its internal space, thereby completing the separation and classification of the plastic particles inside it. After the classification is completed, the plastic particles are sequentially extracted from the separation box 19 and the inside of the accommodating bin 2.

[0049] The technical effect of particle classification is achieved by using multiple separation boxes 19 in conjunction with the filter screen 20 inside the separation box 19. The size of the particles filtered by the filter screen 20 inside the separation box 19 can be adjusted as needed. Moreover, during filtering, the power supply of the drive motor 9 can be interrupted and the separation box 19 containing the particles of the required particle size can be pulled out from the cabinet 21. This feature can interrupt the process and flexibly take out the plastic particles. The taking-out operation is relatively simple. The structure of the separation box 19 and the cabinet 21 has high structural reliability. The frame structure composed of the support shell 1 and the first reinforcement strip 5 and the second reinforcement strip 6 has high structural strength.

[0050] The driving motor 9 rotates to drive the driving wheel 14, and the driving wheel 14 rotates the driving rod axis 12 to pull the connecting rod 10 to move. The connecting rod 10 moves the pulling rod axis 13 to drive the connecting end block 11 to allow the cabinet 21 to slide along the movement direction of the guide groove 17. The cabinet 21 is shaken by the reciprocating motion of the cabinet 21, driving the separation box 19 and the plastic particles inside it to continuously contact the filter screen 20 below it to complete the classification of the plastic particles.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
