Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste-to-energy pretreatment technology, specifically a waste incineration power generation pretreatment device. Background Technology
[0002] Metal recycling is particularly important in the waste treatment process. Among various waste treatment equipment, metal adsorption mechanisms are key components and are widely used in automatic sorting systems. Their main function is to separate metal parts from the mixed materials in the waste through magnetic force or other adsorption principles, so as to realize the recycling and reuse of metal resources and reduce the pollution of metal waste to the environment.
[0003] In the prior art, Chinese patent CN202321027756.6 discloses a pretreatment device for municipal solid waste incineration power generation, including a municipal solid waste feeding pipe, a feeding port at the top of the feeding pipe, and a metal adsorption mechanism on one side of the feeding port; a first branch pipe and a second branch pipe are symmetrically arranged at the bottom of the municipal solid waste feeding pipe, and a guide mechanism is arranged between the top ends of the first branch pipe and the second branch pipe; the metal adsorption mechanism includes a mounting frame arranged on one side of the feeding port, an electromagnet is arranged inside the mounting frame, an opening is provided at one end of the mounting frame near the middle of the feeding port, and several screws are arranged on the side of the mounting frame away from the middle of the feeding port, with one end of the screw penetrating the side wall of the municipal solid waste feeding pipe and connected to a fixing nut. This utility model can efficiently separate metal items from municipal solid waste, improve the recycling rate of metal resources, and reduce resource waste;
[0004] Chinese patent CN202321027756.6 places the metal adsorption mechanism on one side of the waste inlet. Although this layout can achieve preliminary adsorption and separation of metal items, it has obvious limitations in practical applications. During the waste feeding process, due to the complex composition and diverse shapes of the waste, and the disordered accumulation of materials during feeding, metal items far from the metal adsorption mechanism are easily blocked by other objects. Once the metal items are blocked, the magnetic force or adsorption force of the adsorption mechanism cannot effectively act on the metal items, resulting in the metal items not being captured and separated in a timely and accurate manner. This not only reduces the efficiency and recovery rate of metal recycling, but also prevents a large amount of valuable metal resources from being effectively utilized. Therefore, a waste incineration power generation pretreatment device is proposed to address the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a waste incineration power generation pretreatment device to solve the problem in Chinese patent CN202321027756.6, which places the metal adsorption mechanism on one side of the waste inlet. Although it can initially adsorb and separate metal items, the complex composition of the waste and the disorderly accumulation during feeding make it easy for metal parts far from the adsorption mechanism to be blocked, resulting in the adsorption force being unable to play its role and the inability to capture and separate metal parts in a timely and accurate manner, thus reducing the efficiency and recovery rate of metal recycling.

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.
[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0028] Please see Figure 1-6 This utility model provides a technical solution:
[0029] A waste incineration power generation pretreatment device includes a shell 1, with a feeding connecting cylinder 2 fixedly connected to the top of the shell 1. The inner side of the shell 1 communicates with the inner side of the feeding connecting cylinder 2, and a metal adsorption assembly 3 is fixedly connected to the inner side of the feeding connecting cylinder 2. A recycling assembly 5 is installed below the shell 1. The metal adsorption assembly 3 includes a mounting cylinder 31, with a mounting base 32 fixedly connected to the inner side of the mounting cylinder 31. Electromagnets 33 are fixedly connected to both sides of the front end face of the mounting base 32. A conductive block 34 made of silicon steel is fixedly connected between two electromagnets 33, and a conductive plate 35 made of silicon steel is fixedly connected between two conductive blocks 34. Silicon steel has good magnetic permeability and can effectively conduct the magnetic force generated by the electromagnets 33 to the metal adsorption extension shaft 36. The metal adsorption extension shaft is rotatably connected to the inner side of the conductive plate 35. 36. A bushing 37 for cooperating with the metal adsorption extension shaft 36 is connected through the middle of the inner side of the mounting base 32; the metal adsorption extension shaft 36 includes an adsorption shaft body 361, an adsorption groove 362 is opened on the outer surface of the adsorption shaft body 361, an agitator 363 is fixedly connected to the outside of the adsorption shaft body 361, a contact ball 364 is fixedly connected to the front end of the adsorption shaft body 361, and a protective rod 365 made of high-strength engineering plastic is fixedly connected to the rear end of the adsorption shaft body 361, which can effectively prevent the magnetic force of the electromagnet 33 from affecting the drive motor 4, and has good wear resistance and chemical corrosion resistance, and can adapt to the waste treatment environment. A sealing ring 366 is fixedly connected to the middle of the outer wall of the protective rod 365; the protective rod 365 is rotatably connected to the bushing 37, and the outer side of the sealing ring 366 cooperates with the inner side of the bushing 37.
[0030] As a further implementation of this solution, bearings 367 are fixedly installed on both sides of the outer wall of the protective rod 365. This design effectively reduces the frictional resistance during rotation, ensuring that the metal adsorption extension shaft 36 can rotate stably and smoothly for a long time, avoiding shaft wear due to excessive friction, and extending the service life of the equipment. The bearings 367 and the protective rod 365 are located on the same central axis. The bearings 367 are located inside the bushing 37. The protective rod 365 is a three-section cylinder. The rear end of the protective rod 365 extends to the outside of the feed connecting cylinder 2. Four drive motors 4 arranged in a circle are fixedly connected to the outer wall of the feed connecting cylinder 2 through the motor base. The position of the drive motor 4 corresponds to the position of the protective rod 365. The drive shaft of the drive motor 4 is fixedly connected to the rear end of the protective rod 365. This layout realizes multi-point drive, which can provide a more uniform and stable driving torque compared with single-point drive.
[0031] As a further implementation of this scheme, the vertical cross-section of the conduction block 34 is trapezoidal, the conduction plate 35 and the electromagnet 33 are parallel to each other, and the conduction plate 35 and the bushing 37 are located on the same central axis. The inclined surface of the trapezoid helps to reduce the retention of liquid in the waste.
[0032] As a further implementation of this solution, the adsorption shaft body 361 and the protective rod 365 are located on the same central axis. The outer surface of the adsorption shaft body 361 has multiple adsorption grooves 362, which are arranged in a circular pattern. This arrangement increases the contact area with metal objects, enabling the adsorption of more metal objects and increasing the amount of metal adsorption.
[0033] As a further implementation of this solution, the recycling component 5 includes two recycling hoppers 51, which are symmetrically fixed at the bottom of the outer shell 1. The inner side of the recycling hoppers 51 is connected to the inner side of the outer shell 1. A servo motor 52 is fixedly connected to the bottom of the outer wall of the outer shell 1 via a motor mount. An adjusting shaft 53 is fixedly connected to the drive shaft of the servo motor 52. The adjusting shaft 53 extends into the interior of the outer shell 1. A recycling baffle 54 is fixedly connected to the outer side of the adjusting shaft 53. The recycling baffle 54 is located above the recycling hoppers 51. The servo motor 52 drives the adjusting shaft 53 to rotate, thereby moving the recycling baffle 54. This design can flexibly control the falling direction of the waste. After ordinary waste is recycled, the position of the recycling baffle 54 can be adjusted by the servo motor 52 to guide the metal items to the other recycling hopper 51.
[0034] Workflow: First, a comprehensive inspection of all components of the device is conducted to ensure that the outer shell 1, feeding connecting cylinder 2, metal adsorption assembly 3, and recycling assembly 5 are securely installed without any looseness or damage. Power is supplied to the waste incineration power generation pretreatment device via an external power source, and the power connections of the drive motor 4 and servo motor 52 are checked for proper operation. A test is performed to ensure smooth startup. The circuit connection of the electromagnet 33 is checked to ensure it can generate magnetic force normally after being powered on. Next, the waste is conveyed by the conveying equipment to the top of the feeding connecting cylinder 2. Under the force of gravity or the pushing action of the conveying equipment, the waste enters the inside of the feeding connecting cylinder 2. The power to the electromagnet 33 is turned on in advance to generate magnetic force. As the waste enters the outer shell 1 from the feeding connecting cylinder 2, it passes through the metal adsorption assembly 3. At this time, the drive motor 4 drives the metal adsorption extension shaft 36 to rotate. The adsorption groove 362 on the metal adsorption extension shaft 36 increases the contact area with the metal object. The stirring block 363 agitates the waste, preventing... To prevent blockage, the electromagnet 33 is used to better attract metal items in the waste to the adsorption shaft body 361 of the metal adsorption extension shaft 36. The spherical structure of the contact ball 364 helps the waste fall smoothly. The protective rod 365 prevents the magnetic force from affecting the drive motor 4. The sealing ring 366 plays a sealing role to prevent liquid in the waste from leaking to the outside of the feed connecting cylinder 2. The ordinary waste that has been adsorbed continues to fall to the bottom of the outer shell 1 and falls into one of the recycling hoppers 51 for further processing. After the ordinary waste is recycled, the servo motor 52 is started and the position of the recycling baffle 54 is adjusted so that the top of the other recycling hopper 51 is exposed. Then the power of the electromagnet 33 is turned off. At this time, the magnetic force disappears. The metal items that were originally adsorbed on the metal adsorption extension shaft 36 fall into the corresponding recycling hopper 51 due to the loss of magnetic force. After the recycling of waste and metal is completed, the drive motor 4 and the servo motor 52 are turned off in sequence to stop the operation of the device.
