Description

Technical Field

[0001] The utility model relates to the technical field of slag recovery in power plants, in particular to a recovery device for treating slag in garbage incineration power plants. Background Art

[0002] Waste incineration power plants are specially designed to fully burn waste so that the heat generated can be used to generate electricity, turning waste into treasure. After incineration, waste will be recycled in the form of residue. Some of the waste contains metal materials and has recycling value. During the recycling process, the residue is separated from the metal and the dust on the metal surface is collected through a dust collection box to prevent dust pollution. This may affect the accuracy of metal classification. The residue contains a large amount of slag with larger particles. When collected through a dust collection box, there are the following problems: Due to the large particles in the residue, they may not be effectively sucked into the dust collection box, but enter the subsequent processing process together with the metal, resulting in a decrease in the separation efficiency of metal and residue.

[0003] To this end, we propose a recycling device for treating slag in a waste incineration power plant. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example

[0018] See also Figure 1-Figure 3The figure shows a recycling device for treating slag in a waste incineration power plant, comprising a slag recycling box 1, a separation box 2 is provided below the slag recycling box 1, a first conveying device 3 is provided inside the separation box 2, a dust cleaning plate 4 is provided above the first conveying device 3, a first classifying wheel 5 for generating airflow is provided inside the first conveying device 3, a guide fan 6 is provided above the surface of the first conveying device 3, a protective plate 7 is provided below the first conveying device 3, a second conveying device 8 is provided below the protective plate 7, a second classifying wheel 9 is provided inside the second conveying device 8, a third conveying device 10 is provided above the second conveying device 8, an electromagnetic device 11 is provided inside the third conveying device 10, and a guide plate 12 is provided above the third conveying device 10. The present invention uses a first conveying device provided inside the separation box, a dust cleaning plate provided above the first conveying device, and a first classifying wheel provided inside the first conveying device. A guide fan and a separation channel are provided on both sides above the position of the first classifying wheel, so as to use the airflow principle to accurately separate the particles and metal materials of the residue passing through.

[0019] Furthermore, a second protective plate 201 is provided on the inner wall of the separation box 2, and one end of the second protective plate 201 is slidably connected to the surface of the first conveying device 3 and the second conveying device 8. The protective plate ensures that the material is at a specified position of the conveying device, which provides convenience for subsequent material processing.

[0020] Furthermore, a separation channel for guiding the residue to pass is provided on one side of the separation box 2, and a plurality of guide fans 6 distributed linearly are provided on one side of the separation channel. The position of the separation channel is consistent with the position of the first classifying wheel 5. When the material is transported to the position connected to the separation channel on the first conveying device, due to the height difference between the two, after the first classifying wheel cooperates with the guide fan, larger particles and ash can smoothly slide or roll into the separation channel, while ensuring that metal materials can pass smoothly.

[0021] Furthermore, a collecting box 202 is provided at the bottom of the separation channel, and a magnetic metal storage box 13 is provided on one side of the collecting box 202. The existence of the collecting box can conveniently collect the graded materials, avoiding the scattering and mixing of the materials, which also provides convenience for subsequent material processing and recycling.

[0022] Furthermore, the feed port of the magnetic metal storage box 13 is highly consistent with the guide plate 12. The high consistency ensures that the metal particles can smoothly slide from the guide plate to the feed port of the magnetic metal storage box, and no additional adjustment or operation is required between the two, thereby reducing production steps and time costs.

[0023] Furthermore, the first conveying device, the second conveying device and the third conveying device are all composed of a conveyor belt, a support roller, a guide wheel and a motor, and there are gaps in the conveyor belts to achieve suspension of the materials.

[0024] In this solution, the working process is as follows: First, the slag is dropped from the inside of the slag recovery box into the separation box. When the slag enters the separation box, it first contacts the first conveyor. Then, the first grading wheel configured inside the first conveyor generates airflow to perform preliminary grading treatment on the slag. While grading, the guide fan above the device works to form a strong suction force to help suck away dust and small particles, ensuring that large particles of slag can be smoothly processed in the next step. After that, when the remaining metal material passes through the cleaning plate, the surface of the metal material will be further cleaned.

[0025] After that, it falls into the second conveyor through the protective plate, and is further cleaned on the surface by the second grading wheel configured inside the second conveyor. At the same time, during the movement, the magnetic metal materials will be adsorbed on the surface of the third conveyor by the electromagnetic device, rotate clockwise, and be guided into the magnetic metal storage box by the guide plate, while the non-magnetic metal materials will continue to move with the second conveyor and wait for recycling.

[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
