Description

Technical Field

[0001] The utility model relates to the technical field of fly ash processing, in particular to an iron remover used for fly ash processing. Background Art

[0002] Fly ash is a waste discharged by power plants. It is also fine ash collected from the flue gas after coal combustion. It seriously pollutes the environment, especially water sources and the atmosphere. However, it is also an underutilized resource. In the process of extracting useful components from fly ash, the iron oxide contained in the ash always exists as an impurity. In the extraction process, the presence of iron will affect the purity of the extract. Therefore, removing iron from fly ash is of great significance to improving the purity of useful components and the comprehensive utilization rate of fly ash. The working principle of a general iron remover is to adsorb the ferromagnetic substances in fly ash through magnetic force, so as to achieve the purpose of iron removal. When collecting the adsorbed ferrous substances, scrapers or brushes are usually used to separate and collect them, which makes it difficult to collect them cleanly. In addition, fly ash will clump due to moisture and other reasons, and the ferrous substances in the agglomerated fly ash are often difficult to collect. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide an iron remover for fly ash processing.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0020] 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 of 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.

[0021] Please participate Figure 1-4 As shown: a deironing machine for fly ash processing, including a shell 1, a feed port 2 is opened on the top of the shell 1, a discharge port 13 is opened on one side of the shell 1, a first conveyor belt 3 is arranged at the bottom of the feed port 2, one end of the first conveyor belt 3 is sleeved on the conveying shaft C17, the conveying shaft C17 is connected to the motor 12, a motor base 121 is fixedly installed on the side of the shell 1, and the motor 12 is fixedly installed on the motor base 121.

[0022] A rake tooth 4 is fixedly provided at one end of the top of the first conveyor belt 3 near the feed port 2, and the rake tooth 4 is fixedly mounted on the housing 1. The rake tooth 4 can evenly evacuate the fly ash raw material. An upper roller 5 is rotatably provided at the top of the first conveyor belt 3, and a lower roller 6 is provided in the middle of the first conveyor belt 3. The fly ash raw material agglomerated on the first conveyor belt 3 can be crushed by the cooperation of the upper roller 5 and the lower roller 6. A gear is fixed on one end of the shaft side of the upper roller 5, and a chain B21 is sleeved on the gear of the upper roller 5, and the other end of the chain B21 is sleeved on the gear on the shaft side of the conveying shaft C17.

[0023] A second conveyor belt 7 is obliquely arranged below one end of the first conveyor belt 3. The second conveyor belt 7 is sleeved on the conveyor shaft A14, the conveyor shaft B19 and the guide shaft A18. A magnetic conveyor belt 8 is also sleeved inside the second conveyor belt 7. The magnetic conveyor belt 8 is sleeved on the conveyor shaft A14, the conveyor shaft B19 and the guide shaft B181. The width of the magnetic conveyor belt 8 is narrower than the width of the second conveyor belt 7. Therefore, the conveyor shaft A14 can drive the magnetic conveyor belt 8 to rotate while also driving the second conveyor belt 7 to rotate. A collecting frame 10 is arranged at the bottom of the conveyor shaft B19 for collecting fallen ferrous materials. Gears are fixedly arranged at one end of the conveyor shaft C17 and the conveyor shaft A14. The gears on the conveyor shaft C17 and the conveyor shaft A14 are connected by a chain A20. In addition, a dredging rod 9 is fixedly arranged at one end of the top of the second conveyor belt 7 near the first conveyor belt 3. The dredging rod 9 is fixedly installed on the housing 1, which can dredge the fly ash raw materials to the middle, so that the magnetic conveyor belt 8 in the middle can absorb ferrous materials. In addition, a plurality of supporting legs 15 are fixedly disposed on the bottom of the housing 1 .

[0024] Working principle: When the equipment is working, the fly ash raw material falls from the feed port 2 onto the first conveyor belt 3, and first passes through the rake teeth 4. The rake teeth 4 can evenly evacuate the fly ash raw material, and then pass through the upper roller 5 and the lower roller 6 to crush the fly ash agglomerated in the fly ash raw material. In the next step, the fly ash raw material falls onto the second conveyor belt 7. First, the fly ash raw material is gathered to the middle of the conveyor belt by the guide rod 9. Because a magnetic conveyor belt 8 is provided in the middle part of the second conveyor belt 7, the fly ash raw material that does not contain ferrous substances falls directly to the discharge port 13 at the bottom of the second conveyor belt 7 due to inertia, and the adsorbed ferrous substances continue to run to the bottom of the second conveyor belt 7 under the adsorption of the magnetic conveyor belt 8. When transported to the guide shaft A18, the second conveyor belt 7 loses its adsorption force, and the adsorbed ferrous substances just fall into the collecting frame 10 at the bottom.

[0025] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
