Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel recycling technology, specifically a conveying mechanism for recycling pyrolysis products. Background Technology

[0002] The recycling process for photovoltaic panels typically involves shredding the discarded panels in a shredder, then crushing the shredded material in a specialized crusher to break down the EVA film and monocrystalline silicon wafers. The broken material is then fed into a collector by an induced draft fan, and after sorting, silicon is obtained. The remaining mixture is fed into a specialized pulverizer, then through an airlock into an airflow separator. The airflow and vibration process collects the metals and plastics, while also collecting the dust generated by the airflow separator. The recycling process requires the use of a conveyor mechanism for circulating pyrolysis products.

[0003] The existing pyrolysis product circulation conveying mechanism mainly consists of a base and a conveyor belt. By starting the conveyor belt, the plastics related to the photovoltaic panels are transported to the tunnel furnace to replenish energy, reducing internal consumption in production and burning off related pollutants. Some materials will be adsorbed on the surface of the conveyor belt during the conveying process. When the conveyor belt carries the adsorbed materials into the inside of the conveyor belt, the adsorbed materials will fall into the inside of the conveyor belt frame under the combined influence of machine vibration and gravity. Long-term accumulation of materials inside the conveyor belt frame will block the normal operation of the conveyor belt. Utility Model Content

[0004] The purpose of this invention is to provide a conveying mechanism for pyrolysis product circulation, in order to solve the problem in the above-mentioned conveying mechanism for pyrolysis product circulation where, during the material conveying process, the material falls into the inside of the conveyor belt frame under the combined influence of machine vibration and gravity, and the accumulation of material affects the operation of the conveyor belt.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying mechanism for circulating pyrolysis products, comprising a base, a conveyor belt, and a collecting section. The conveyor belt is fixed above the base, and the collecting section is disposed above the base. The collecting section has a collecting frame fixed above the base, and an mounting frame is fixed above the collecting frame. A motor is fixed inside the mounting frame, and a reciprocating screw is fixed at the output end of the motor. A spiral conveying rod is fixed at the bottom end of the reciprocating screw, and the bottom end of the spiral conveying rod is rotatably connected to the bottom of the inner side of the collecting frame. The collecting frame has an outlet and an inlet on the side of the conveyor belt, and an outlet frame is fixed on the side of the outlet. The spiral conveying rod rotates to drive the material to move from bottom to top inside the collecting frame and be discharged through the outlet frame.

[0006] By adopting the above technical solution, starting the motor can drive the reciprocating screw to rotate, which in turn drives the screw conveyor to rotate. The rotation of the screw conveyor causes the collected material to move vertically and be discharged through the discharge frame. The material discharged from the discharge frame will fall back onto the conveyor belt for recycling, thereby reducing the accumulation of material inside the conveyor belt frame.

[0007] Preferably, the collecting part further includes a threaded block disposed inside the mounting frame, and the threaded block is threadedly connected to the reciprocating lead screw, and a connecting rod is fixedly disposed on one side of the discharge frame, and a vibrating rod is fixedly disposed at the bottom of the connecting rod.

[0008] By adopting the above technical solution, the motor will drive the reciprocating screw to rotate during operation. The rotation of the reciprocating screw will drive the threaded block to move vertically back and forth. The vertical movement of the threaded block will drive the vibrating rod to move vertically and strike the bottom of the discharge frame, thereby reducing the occurrence of material blockage in the discharge frame.

[0009] Preferably, the discharge frame is inclined, and the bottom of the discharge frame is located above the conveyor belt.

[0010] By adopting the above technical solution and setting the discharge frame to an inclined shape, the material can fall onto the conveyor belt under the influence of gravity for subsequent recycling.

[0011] Preferably, there are two sets of connecting rods, and the two sets of connecting rods are the same in shape and size, and both sets of connecting rods are connected to the vibrating rod.

[0012] By adopting the above technical solution and setting two sets of connecting rods, the vibrating rod can be driven to move vertically more effectively, ensuring the stability of the vibrating rod during its movement.

[0013] Preferably, the vibrating rod has a sloping top and a buffer pad is provided at the sloping top.

[0014] By adopting the above technical solution, the impact force when the vibrating rod collides with the discharge frame is buffered by setting a buffer pad, thereby reducing the possibility of damage to the vibrating rod and the discharge frame.

[0015] Preferably, sliding protrusions are fixed on both sides inside the mounting frame, and the sliding protrusions are slidably connected to the connecting rod.

[0016] By adopting the above technical solution, the connecting rod is limited by the sliding protrusion, ensuring the stability of the connecting rod during vertical movement.

[0017] Preferably, a limiting block is fixed above the inner bottom plate of the conveyor belt, and the limiting block is in contact with the feed inlet side of the collection frame.

[0018] By adopting the above technical solution, the collected material can be limited by setting a limit block, so that the material can enter the collection box through the feed port for conveying.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) By starting the motor, the reciprocating screw can be driven to rotate. The rotation of the reciprocating screw can drive the screw conveyor to rotate. The rotation of the screw conveyor drives the collected material to move vertically and is discharged through the discharge frame. The material discharged from the discharge frame will fall back to the top of the conveyor belt for recycling, thereby reducing the accumulation of material inside the conveyor belt frame.

[0021] (2) During the operation of the motor, the reciprocating screw will rotate. The rotation of the reciprocating screw will drive the threaded block to move vertically back and forth. The vertical movement of the threaded block will drive the vibrating rod to move vertically and strike the bottom of the discharge frame, thereby reducing the occurrence of material blockage in the discharge frame.

[0028] 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.

[0029] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0030] Example 1

[0031] Please see Figure 1-5This embodiment provides a technical solution: a conveying mechanism for circulating pyrolysis products, including a base 1, a conveyor belt 2, and a collection section 3. The conveyor belt 2 is fixed above the base 1 and connected to an external power source. By activating the conveyor belt 2, the pyrolysis products from the pyrolysis furnace can be transported to the tunnel furnace. The collection section 3 is located above the base 1 and has a collection frame 301 fixed above the base 1. The collection frame 301 is connected to the base 1 by multiple sets of bolts to improve the stability of the overall structure. An installation frame 302 is fixed above the collection frame 301, and the collection frame 301 is connected to the installation frame 302 by welding to prevent the installation frame 302 from separating from the collection frame 301. A motor 303 is fixed inside the installation frame 302. The motor 303 is an electric motor, and its working principle is to convert electrical energy into mechanical energy. It utilizes an energized coil (i.e., stator winding) to generate a rotating magnetic field, which acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric rotational torque. Electric motors are classified into DC motors and AC motors according to the power source they use. Most motors in power systems are AC motors, which can be synchronous motors or asynchronous motors (where the speed of the stator magnetic field and the speed of the rotor are not synchronized). An electric motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying conductor in a magnetic field depends on the direction of the current and the direction of the magnetic field lines. The electric motor operates on the principle that a magnetic field exerts a force on an electric current, causing the motor to rotate. Motor 303 is mounted inside mounting frame 302 via multiple sets of bolts and is connected to an external power source. A reciprocating lead screw 304 is fixed to the output end of motor 303, and is connected to the output end of motor 303 via bolts. The operation of motor 303 drives the reciprocating lead screw 304 to rotate. A spiral conveying rod 305 is fixed to the bottom end of the reciprocating lead screw 304, and is welded to the spiral conveying rod 305. Rotation of the reciprocating lead screw 304 drives the spiral conveying rod 305 to rotate, and the bottom end of the spiral conveying rod 305 is rotatably connected to the bottom inner side of collection frame 301. The collection frame 301 controls the spiral conveying rod 305. 5. A limit is set at the bottom to ensure the stability of the spiral conveyor 305 during rotation. The collection frame 301 is located on the side of the conveyor belt 2 and has a discharge port and a feed port from top to bottom. A discharge frame 306 is fixed on the discharge port side. The discharge frame 306 is connected to the collection frame 301 by bolts. The material can be discharged through the discharge frame 306 and fall onto the conveyor belt 2. The spiral conveyor 305 rotates to drive the material to move from bottom to top inside the collection frame 301 and be discharged through the discharge frame 306. The discharge frame 306 has an inclined shape and the bottom of the discharge frame 306 is located above the conveyor belt 2. By setting the discharge frame 306 to an inclined shape, the material can fall onto the conveyor belt 2 under the influence of gravity for subsequent recycling.

[0032] Example 2

[0033] Please see Figure 1-5 The collecting unit 3 also has a threaded block 307 disposed inside the mounting frame 302, and the threaded block 307 is threadedly connected to the reciprocating screw 304. The rotation of the reciprocating screw 304, under the influence of the thread, can drive the threaded block 307 to move vertically. A connecting rod 308 is fixedly mounted on one side of the threaded block 307 and the connecting rod 308 is connected to the threaded block 307 by welding. The movement of the threaded block 307 can drive the connecting rod 308 to move in the same way. A vibrating rod 309 is fixedly mounted at the bottom of the connecting rod 308, and the vibrating rod 309 is connected to the connecting rod 308 by bolts, facilitating the disassembly and replacement of the vibrating rod 309 by personnel. The movement of the connecting rod 308 can drive the vibrating rod 309 to move. Two sets of connecting rods 308 are provided, and both sets of connecting rods 308 are identical in shape and size, and both sets of connecting rods 308 are connected to the vibrating rod 309. The connecting rod 308 can better drive the vibrating rod 309 to move vertically, ensuring the stability of the vibrating rod 309 during movement. The upper part of the vibrating rod 309 is sloping, and a buffer pad is provided at the sloping part. The buffer pad is provided to buffer the impact force when the vibrating rod 309 collides with the discharge frame 306, reducing the possibility of damage to the vibrating rod 309 and the discharge frame 306. Sliding protrusions 310 are fixed on both sides inside the mounting frame 302, and the sliding protrusions 310 are slidably connected to the connecting rod 308. The sliding protrusions 310 limit the connecting rod 308, ensuring the stability of the connecting rod 308 during vertical movement. A limiting block 4 is fixed on the upper part of the inner bottom plate of the conveyor belt 2, and the limiting block 4 is attached to the feed port side of the collection frame 301. The limiting block 4 can limit the collected material, allowing the material to enter the collection frame 301 through the feed port for conveying.

[0034] Working principle: First, when the conveyor belt 2 transports materials, the materials adsorbed on the surface of the conveyor belt 2 will fall to the bottom of the conveyor belt 2 frame due to gravity and machine vibration. Since the bottom of the conveyor belt 2 frame is sloping, the materials will gradually enter the collection frame 301 through the feed inlet due to gravity. The motor 303 is started, and the operation of the motor 303 will drive the reciprocating screw 304 to rotate. The rotation of the reciprocating screw 304 will drive the screw conveyor 305 to rotate. The rotation of the screw conveyor 305 will transport the materials from the bottom inside the collection frame 301 to the top inside the collection frame 301. The materials will gradually be discharged through the discharge frame 306. Since the bottom of the discharge frame 306 is above the conveyor belt 2, the materials will fall back to the top of the conveyor belt 2 due to gravity for transport.

[0035] Secondly, since the reciprocating screw 304 is threadedly connected to the threaded block 307, and the threaded block 307 is in contact with both sides of the inner wall of the mounting frame 302, the rotation of the reciprocating screw 304 will drive the threaded block 307 to perform vertical reciprocating motion under the influence of the thread. The movement of the threaded block 307 will drive the connecting rod 308 to move, and the movement of the connecting rod 308 will drive the vibrating rod 309 to move. The reciprocating motion of the vibrating rod 309 will slightly tap the bottom of the discharge frame 306, causing the discharge frame 306 to vibrate to a certain extent, thereby reducing the occurrence of material blockage in the discharge frame 306.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
