[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1: This embodiment is used to solve the problem that it is impossible to accurately distinguish mixed plastics, which contain multiple different types of plastics with different physical and chemical properties, which undoubtedly increases the complexity of subsequent waste treatment.

[0037] See also Figure 1 - Figure 6 As shown, this embodiment is an environmentally friendly plastic degradation treatment device, including a fixed frame 1, a conveyor belt 101 is fixedly installed in the fixed frame 1, a connecting frame 2 is fixedly installed on the fixed frame 1, a fixed box 201 is movably installed in the connecting frame 2, a screw rod 306 is movably installed in the connecting frame 2, a motor is fixedly installed on one side of the connecting frame 2, the output end of the motor is fixedly connected to the screw rod 306, a movable nut is movably installed on the screw rod 306 through a thread, and the movable nut is fixedly connected to the fixed box 201.

[0038] In actual use, if the crushing size is to be adjusted, the motor is started to drive the screw rod 306 to rotate, and the thread is used to drive the movable nut to move on the screw rod 306. The fixed box 201 is composed of a box body 1 307 and a box body 2 308. The crushing roller 202 is fixedly installed in the box body 1 307 and the box body 2 308. The movable nut drives the box body 1 307 and the box body 2 308 to move, and then the distance between the two crushing rollers 202 is adjusted to control the crushing size of the plastic.

[0039] A card block is fixedly installed on one side of box body 1 307 close to box body 2 308, and a card slot is opened on one side of box body 2 308. The card block is located in the card slot. When box body 1 307 and box body 2 308 move, the card block moves in the card slot. By cooperating with the card block and the card slot, the stability of box body 1 307 and box body 2 308 when moving is guaranteed, and at the same time, it is guaranteed that plastic fragments will not fly out of the fixed box 201.

[0040] The fixed box 201 is located above the conveyor belt 101, and a crushing roller 202 is fixedly installed in the fixed box 201. A sorting component 3 is fixedly installed on the fixed frame 1. The sorting component 3 includes a spectrum array 301, a nozzle 302 and a guide channel 303. The spectrum array 301 is fixedly installed on one side of the connecting frame 2. The spectrum array 301 is used to scan the surface of the fragments and identify the material (PET, HDPE, PVC, etc.) through the vibration characteristics of chemical bonds such as CH and C=O. The nozzle 302 is fixedly installed on the fixed frame 1. There are multiple nozzles 302, and the number of nozzles 302 is determined according to actual needs. In this embodiment, four nozzles 302 are provided. The guide channel 303 is fixedly installed on the fixed frame 1, and the position of the guide channel 303 is adapted to the nozzle 302.

[0041] A reactor 304 is fixedly installed at one end of the guide channel 303 away from the fixed frame 1, and a liquid spray pipe 305 is fixedly installed on the top of the reactor 304. A preheating area, a reaction area and a heat preservation area are provided in the reactor 304. The liquid spray pipe 305 is located in the reaction area. The temperature of the preheating area is 150-250°C, the temperature of the reaction area is 300-400°C, and the temperature of the heat preservation area is 200-300°C.

[0042] The preheating zone is usually 200°C, which is used to activate the plastic surface and make it easier to adsorb catalysts. The reaction zone is usually 320°C, and the catalyst is sprayed onto the surface of the plastic fragments through the spray pipe 305 to induce the breakage of CC bonds. The insulation zone is usually 250°C, which is used to gasify and separate small molecular hydrocarbons.

[0043] A rotating rod 309 is movably installed in the reactor 304, a motor is fixedly installed at one end of the reactor 304, the output end of the motor is fixedly connected to the rotating rod 309, a spiral blade 310 is fixedly installed on the rotating rod 309, and a discharge port 311 is arranged at the bottom of the reactor 304, the discharge port 311 is close to the end of the reactor 304 away from the motor. When the plastic fragments enter the reactor 304, the motor starts to drive the rotating rod 309 to rotate, and then the spiral blade 310 drives the plastic fragments to move toward the discharge port 311, and after the treatment in the insulation zone is completed, the plastic fragments are discharged through the discharge port 311.

[0044] The plastic to be degraded is put into a fixed box 201, and the plastic is crushed by a crushing roller 202. The crushed plastic fragments fall on a conveyor belt 101, and the conveyor belt 101 drives the fragments to move to a guide channel 303. During the movement, the type of the fragments is detected by a spectrum array instrument 301. After the detection, the corresponding jet head 302 is started, and the fragments are blown into the corresponding guide channel 303 by a high-speed airflow, and the fragments are transported to a reactor 304 through the guide channel 303 for degradation treatment, so as to achieve accurate distinction of plastic fragments.

[0045] Embodiment 2: This embodiment is used to solve the problem that the recycling technology requirements of different plastic materials vary greatly, and many plastics may not be recyclable after mixed processing.

[0046] See also Figure 7 As shown, it also includes a control panel 4, which is fixedly mounted on one side of the fixing frame 1. The control panel 4 includes a server, a by-product monitoring module, a gas detection module and a remote monitoring terminal;

[0047] The by-product monitoring module monitors the by-products generated after processing, generates a normal sorting signal or an abnormal sorting signal through process analysis, and sends the abnormal sorting signal to the remote monitoring terminal via the server;

[0048] The gas detection module monitors the impurity concentration value and energy consumption detection value generated during the degradation process, generates a qualified processing signal or an abnormal processing signal through process analysis, and sends the abnormal processing signal to the remote monitoring end through the server;

[0049] The specific operation process of the by-product monitoring module includes: collecting the impurity content data of the by-products after plastic degradation treatment, if the impurity content data is greater than or equal to the preset threshold value, judging that the sorting component 3 is in a sorting misjudgment state; obtaining the total time length of the by-product in the sorting misjudgment state per unit time and marking it as the total time value of sorting risk, and calculating the average of all impurity contents in the by-products per unit time to obtain a total inspection value; numerically calculating the total time value of sorting risk and the total inspection value to obtain a sorting risk value, if the sorting risk value is greater than the preset sorting risk threshold, generating a sorting abnormality signal.

[0050] The total inspection value is collected by a laser scattering particle counter fixedly installed in the reactor 304. The total inspection value Wi represents the residual impurity content after degradation. The higher the value, the more residual impurities. The total time value Ti of sorting risk is collected by a timing module in the control panel 4. When the total inspection value is greater than a preset threshold, the timing starts. The larger the total time value Ti of sorting risk, the higher the risk of abnormal plastic sorting.

[0051] After obtaining the total time value Ti and the total inspection value Wi of the sorting risk, the sorting risk value Xo is obtained through the formula Xo=A*Ti+B*Wi, where A and B are the weight ratio coefficients of the total time value Ti and the total inspection value Wi, respectively, A>B>0, and Xo is represented as the sorting risk value. When the sorting risk value Xo is larger, it means that the total time value Ti of the sorting risk is larger or the total inspection value Wi is larger. At this time, the preset sorting risk threshold Vo stored in the processor is retrieved and compared with the sorting risk value Xo for analysis:

[0052] If the sorting danger value Xo> the preset sorting danger threshold Vo, a sorting abnormality signal is generated, and the total inspection value Wi data is analyzed. The specific operation process includes:

[0053] When the Wi value is 5% to 8%, the main impurities may be inorganic fillers (CaCO3, SiO2) or metal fragments. The cause is that the modified plastics containing fillers (such as glass fiber reinforced PA) or metal impurities are not identified during sorting;

[0054] At this time, the equipment is marked as slightly exceeding the standard, and a control signal is generated and sent to the remote monitoring end. The spectrum array instrument 301 is adjusted through the remote monitoring end, that is, a new inorganic filler characteristic peak is added to the near-infrared spectrum library, and the sorting priority of filler plastics is increased. The pneumatic nozzle pressure is increased from 0.6MPa to 0.8MPa, and the motor is started to drive the screw 306 to rotate, and then the spacing of the crushing rollers 202 is adjusted from 15mm to 10mm, ensuring that the filler plastics are fully crushed and the specific surface area is increased to facilitate degradation.

[0055] When the Wi value is 8% to 15%, the main impurities may be cross-linked polymer particles and halogen compounds. The cause is that thermosetting plastics (such as epoxy resin) or halogen-containing flame-retardant plastics (such as PVC) are mistakenly judged as degradable thermoplastics during sorting;

[0056] At this time, the equipment is marked as moderately exceeding the standard, and an exceeding-standard signal is generated and sent to the remote monitoring end. The spectrum array instrument 301 is adjusted through the remote monitoring end, that is, the near-infrared spectrometer is upgraded to short-wave infrared (SWIR, 1000-2500nm), and the detection sensitivity of the cross-linked structure CN bond (2200nm) and C-Cl bond (1650nm) is enhanced. At the same time, a special sorting channel for high-risk materials is added, and the pneumatic nozzle pressure is increased from 0.6MPa to 0.8MPa.

[0057] When Wi>15%, there are unbroken large particles in the impurities, which is caused by serious errors in the sorting strategy (such as conductive plastics are not isolated), or non-plastic foreign matter (such as rubber, wood) is mixed into the feed;

[0058] At this time, the equipment is marked as seriously exceeding the standard. At this time, the abnormal part of the reactor 304 stops working, and the exceeding standard signal is sent to the remote monitoring end, and the operator immediately repairs the corresponding equipment.

[0059] That is, first make a preliminary judgment on the sorting risk value Xo, and then conduct a detailed analysis of the total inspection value Wi data, which greatly improves the safety of equipment use, accurately locates abnormal equipment, and avoids continuous abnormal damage to equipment.

[0060] The specific operation process of the gas detection module includes:

[0061] Collect gas data during the plastic degradation process, calculate the mean of all gas concentration data per unit time to obtain the gas value, calculate the difference between the gas value and the median of the preset normal gas value range, and take the absolute value to obtain the impurity concentration value;

[0062] The gas quantity value is collected by a gas sensor fixedly installed in the reactor 304. The gas quantity value Qi represents the content of gas generated during the degradation process. The higher the value, the greater the gas concentration. The gas data in the reactor 304 is collected during the time threshold period, with two hours as the time threshold, time as the x-axis, and the gas quantity value as the y-axis. The gas change curve is calculated, and the impurity concentration value is obtained by the formula Zo=K(a1+a2+a3+a4) / 4, where A1, A2, A3 and A4 are the vertical coordinate values ​​under different horizontal coordinates, K is a preset proportional coefficient and K>0, and Zo is the impurity concentration value. The larger the impurity concentration value Zo, the higher the risk of abnormal processing.

[0063] and collecting oxygen consumption data in the degradation area, and marking the amount of oxygen consumption data greater than a preset oxygen consumption data threshold as an energy consumption detection value, performing numerical calculation on the impurity concentration value and the energy consumption detection value to obtain a degradation input detection value, and generating a processing abnormality signal if the degradation input detection value is greater than the preset degradation input detection value;

[0064] The oxygen consumption is collected by a gas flow sensor fixedly installed in the reactor 304. The oxygen consumption Oi represents the amount of oxygen consumed by the degradation reaction per unit time. The higher the value, the higher the energy consumption. The gas change curve is calculated with half an hour as the time threshold, time as the x-axis, and oxygen consumption as the y-axis, and the preset oxygen consumption curve is drawn on the coordinate axis. The part that exceeds the preset oxygen consumption curve per unit time is averaged to obtain the energy consumption detection value Wo.

[0065] After obtaining the impurity concentration value Zo and the energy consumption detection value Wo, the processing input detection value Mo is obtained by the formula Mo=P1*Zo+P2*Wo, P1 and P2 are preset proportional coefficients and P1 and P2 are both greater than 0. The larger the value of the processing input detection value Mo is, the more exhaust gas is generated or the greater the energy consumption is. At this time, the preset processing input detection value Ho stored in the processor is retrieved and compared with the processing input detection value Mo for analysis:

[0066] If the processing input inspection value Mo> the preset processing input inspection value Ho, a processing abnormality signal is generated, and when the remote monitoring end receives the processing abnormality signal, a corresponding warning is issued.

[0067] Combining the first and second embodiments, it can be known that the data of the degradation area can be collected to obtain the normal sorting signal and the qualified processing signal, and the degradation process and the degradation by-products can be comprehensively and efficiently supervised during use, that is, the collected data range is comprehensively analyzed and compared with the preset data range, so as to obtain the relevant evaluation signal, and accordingly send a corresponding early warning to the remote monitoring end to achieve accurate judgment and control of the plastic degradation process, and can also adjust the crushing size and make compensatory adjustments to the abnormal situation of degradation through the cooperation of the screw rod 306 and the fixed box 201, and achieve accurate distinction of plastic fragments through the coordinated use of components such as the crushing roller 202, the nozzle 302 and the guide channel 303.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
