Description

Technical Field

[0001] This utility model relates to the field of waste plastic pyrolysis technology, specifically to a slag discharge device for waste plastic pyrolysis equipment. Background Technology

[0002] Slag discharge from waste plastic pyrolysis equipment refers to the process of removing solid residues (such as carbon black and metallic impurities) generated during pyrolysis from the reactor. The slag discharge device mainly includes a screw propeller and a disturbance device. Its core function is to disrupt the stability of the carbon residue, causing it to fall into the discharge channel. Specifically, a screw propeller is longitudinally positioned at the bottom of the reactor, with its end located within the discharge channel. A drive shaft is parallel to the shaft of the screw propeller, and a device is installed on the drive shaft to disturb the carbon residue. By disrupting the stable structure of the carbon residue, it continuously falls into the screw conveyor, completing the slag discharge. This device pushes the carbon residue into the discharge channel via the screw propeller, while the disturbance device on the drive shaft causes irregular movement of the carbon residue, disrupting its stable structure and ensuring a continuous flow of carbon residue into the discharge channel. This design is particularly effective in horizontally arranged reactors, achieving highly efficient slag discharge.

[0003] However, in actual use, the slag discharge device of the waste plastic pyrolysis equipment has certain limitations at the feeding connection. The ton bag packaging bag needs to be tied to the discharge port of the screw slag discharger, and after packaging, it needs to be removed manually, weighed, and put into storage. It is also necessary to ensure that the carbon black discharge and packaging process is sealed. The operation is not very convenient and is not conducive to improving work efficiency. Based on this, a slag discharge device for waste plastic pyrolysis equipment is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6The slag discharge device of the waste plastic pyrolysis equipment in this embodiment includes a slag discharger housing 1. The slag discharger housing 1 is characterized by: a docking slide rail 2 fixedly installed at its lower end; the docking slide rail 2 consisting of two relatively parallel slide tracks; a discharge port 3 installed at the slag discharge end of the slag discharger housing 1; the discharge port 3 located between the slide tracks; a ton bag 5 that can slide along the docking slide rail 2 to below the discharge port 3; and the discharge port 3 used for docking with the ton bag 5. A drive module is installed on the slag discharger housing 1 to control the slag discharge. The slag is discharged from the slag discharger housing 1 through the discharge port 3 into the corresponding ton bag 5. Power component one and power component two are installed on the slide on one side. Limiting component one is installed on the output end of power component one, and limiting component two is installed on the output end of power component two. Power component one and power component two are used to drive limiting component one and limiting component two to move closer to or away from the slide on the other side. When the limiting component moves closer to the slide on the other side until it contacts the slide, the ton bag 5 is fixed between limiting component one and limiting component two. A weighing module 10 is installed on the docking slide rail 2. The weighing module 10 is used to detect the weight of the ton bag 5 and send a signal to the control unit of the power component.

[0018] In this embodiment, after a 12-hour pyrolysis process, in addition to obtaining pyrolysis oil and non-condensable gas, carbon black is also generated in the pyrolysis furnace. After the furnace body stops heating, air cooling is adopted, and the heat of the outer wall of the furnace body is carried away by the fan. The cooling process takes about 8 hours. During the pyrolysis process, the furnace body rotates slowly and continuously. The furnace body is sealed. When the furnace body cools down to 45~55℃, carbon black is discharged. The carbon black discharge port 3 is connected to the closed spiral slag discharge machine, and the carbon black with a particle size of about 80~100 mesh is directly sent into the ton bag packaging bag.

[0019] Please see Figures 1-6 In this embodiment, the power assembly one includes an electric push rod 6 installed on one side of the slide rail, and a limiting member 1 installed on the output end of the electric push rod 6. The electric push rod 6 is used to drive the limiting member 1 closer to or away from the slide rail on the other side. The power assembly two includes an electric push rod 8 installed on one side of the slide rail, and a limiting member 2 installed on the output end of the electric push rod 8. The electric push rod 8 is used to drive the limiting member 2 closer to or away from the slide rail on the other side. The limiting member one includes a positioning rod 7, one end of which is connected to the output end of the electric push rod 6. The positioning rod 7 is slidably connected to the docking slide rail 2. The limiting member two includes a limiting rod 9, one end of which is connected to the output end of the electric push rod 8. The limiting rod 9 is slidably connected to the docking slide rail 2. The other ends of the positioning rod 7 and the limiting rod 9 are fixedly connected to a limiting block 14. The docking slide rail 2 is provided with a receiving groove 15, and the limiting block 14 is adapted to the receiving groove 15.

[0020] It should be noted that the docking interface 4 of the ton bag 5 can be aligned with the arc-shaped guide opening of the docking slide rail 2, facilitating quick alignment and feeding into the docking slide rail 2 (the docking interface 4 is made of rigid material, making it easy to slide inside the docking slide rail 2). The docking slide rail 2 has multiple openings to facilitate observation of the internal situation. The electric push rod 6 can drive the positioning rod 7 to extend and intercept and position the docking interface 4, making it easy to slide directly into the docking interface 4 and accurately fit and align with the discharge port 3. The electric push rod 8 can drive the limiting rod 9 to extend, working with the positioning rod 7 to hold the docking interface 4 against both sides, ensuring the accuracy and stability of the docking interface 4 and the discharge port 3, further controlling the discharge of material from the slag discharger housing 1, so that it falls into the ton bag 5. A pre-placement position is set on the left side of the docking slide rail 2 to facilitate the workers' cooperation and prepare the next ton bag 5 in advance.

[0021] Another embodiment of electric push rod 6 and electric push rod 8: hydraulic push rods can be set up, and the positioning rod 7 and the limiting rod 9 can be pushed by the two hydraulic push rods respectively, and the control panel can coordinate the operation and run in sequence.

[0022] Please see Figures 1-6 In this embodiment, the ton bag 5 includes a bag body and an integrally fixed docking interface 4 on the bag body. The docking interface 4 is slidably connected to the docking slide rail 2. A flexible connecting strip 16 is fixedly connected to one side of the docking interface 4. A sealing cover plate 17 for opening or closing the docking interface 4 is fixedly connected to the flexible connecting strip 16. The drive module includes a motor 13 and an auger installed on the output end of the motor 13. The motor 13 is used to drive the auger to rotate. The entry end of the docking slide rail 2 is provided with an arc-shaped guide port, which is used to guide the docking interface 4 into the docking slide rail 2.

[0023] It should be noted that upon completion of the collection of the ton bag 5, the weighing module 10 can immediately weigh the ton bag 5. The weighing module 10 is a fixed static load weighing module, ensuring the absolute stability of the weighing surface. It is suitable for occasions where no adjustment or movement is required, such as static weighing systems for stable containers or platforms. The main components of the fixed static load weighing module include a top plate (fixed), a bottom plate, a load cell, load support columns, and support bolts. These components are rigidly connected to ensure that the weighing surface does not move up and down, making it suitable for static weighing scenarios such as containers and platforms. When the ton bag 5 acts on the top plate, the load is transmitted to the load cell through the load support columns and support bolts. The elastic body of the sensor undergoes micron-level deformation, causing a change in the resistance value of the internal strain gauge, forming a Wheatstone bridge effect and outputting a differential voltage signal. After amplification, filtering, and analog-to-digital conversion, this signal is processed by a processing device to output an electrical signal proportional to the weight, achieving accurate measurement. (The weighing module 10 is a conventional weighing mechanism. Because the docking slide rail 2 is set on both sides, it allows...) The weighing module 10 is also designed with two sides. The top plate structure of the weighing module 10 is flush with the docking slide rail 2, which can combine the functions of weighing surface and sliding surface. (The measurement data needs to be synchronized to the control panel and processed by the processing module.) The display panel can display the weighing value, which is convenient for the staff to record at the counting label. Then, the drive component is controlled to retract the positioning rod 7 and the limit rod 9, so that the ton bag 5 can slide out of the docking slide rail 2. The limit block 14 is used to limit the movement space of the positioning rod 7 and the limit rod 9 to prevent them from detaching from the hole and groove structure of the docking slide rail 2. The receiving groove 15 can accommodate the positioning rod 7, the limit rod 9 and the limit block 14, ensuring that the docking interface 4 can slide smoothly and then be covered with the sealing cover plate 17 for storage.

[0024] The working principle of the above embodiments is as follows: In use, align the docking interface 4 of the ton bag 5 with the arc-shaped guide opening of the docking slide rail 2 for quick and easy insertion into the docking slide rail 2. The electric push rod 6 drives the positioning rod 7 to extend and intercept the docking interface 4, allowing it to slide directly into the docking interface 4 and precisely align with the discharge port 3. The electric push rod 8 drives the limiting rod 9 to extend, working in conjunction with the positioning rod 7 to hold the docking interface 4 against both sides, ensuring the accuracy and stability of the docking between the docking interface 4 and the discharge port 3. Further control the discharge machine housing 1 to discharge the material into the ton bag 5. Upon completion of the collection of the ton bag 5, the weighing module 10 immediately weighs the ton bag 5 and displays the value on the display panel for easy recording by staff at the counting label. Then, control the drive component to retract the positioning rod 7 and the limiting rod 9, allowing the ton bag 5 to slide out of the docking slide rail 2 and be covered with the sealing cover 17 for storage.

[0025] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.
