Description

Technical Field

[0001] This utility model relates to the field of metallurgical material processing technology, specifically to a dehydration device for metallurgical materials. Background Technology

[0002] With the development of the steel industry, rich iron ore resources have become increasingly depleted, and lean iron ore resources have been successively developed and utilized to produce iron concentrate, and then artificial rich ore. Depending on the conditions and processing methods, artificial rich ore includes two types: sintered ore and pelletized ore. Metallurgical plants have a large amount of iron-containing waste, among which furnace dust, iron oxide scale, and steel slag can be used as raw materials for sintered ore, and scrap steel can be processed as raw material for steelmaking. The reprocessing of waste requires a dehydration process.

[0003] In the prior art, Chinese Utility Model Application No. CN202323153744.0 discloses an iron ore grading and dewatering device that can improve efficiency. The device includes: a screening shell, a screening cylinder rotatably installed inside the screening shell, several filter holes on the circumferential sidewalls of the screening cylinder, a feed pipe fixedly installed at one end of the screening cylinder through the screening shell, a sealing cap threadedly installed at the other end of the screening cylinder through the screening shell, and two discharge shells below the screening shell, one discharge shell located directly below the discharge port of the screening shell and the other discharge shell located directly below the sealing cap; and a power assembly located inside the screening shell and above the screening cylinder, used to drive the screening cylinder to rotate. This utility model, when in use, prevents iron ore from accumulating during screening, avoiding downtime for disassembly and maintenance, thus reducing work progress. It also prevents ore from piling up, which would lead to slow ore drying and wasted time.

[0004] Although the above technical solution achieves the grading and screening of metallurgical materials, the sealing cover needs to be opened manually during grading to discharge materials of different specifications, which increases the number of manual operation steps. At the same time, the rotation speed of the screening cylinder is not fast enough or its structure cannot effectively distribute the material evenly across the entire screening surface, which may lead to material accumulation or blockage, affecting continuous processing. Therefore, we need to propose a dewatering device for metallurgical materials. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a dehydration device for metallurgical materials, comprising:

[0027] Screening box 1, and dewatering box 2 fixedly connected to the bottom of screening box 1;

[0028] The screening box 1 has an anti-blocking mechanism 4 and a screening mechanism 3 installed in the inner cavity from top to bottom. A material guide channel 10 is provided above the screening box 1. A primary material drop channel 13 is provided at one end of the material guide channel 10. A secondary material drop channel 12 connected to the screening mechanism 3 is provided in the inner cavity of the screening box 1. A vibration motor 9 is provided on the lower surface of the dewatering box 2.

[0029] The dehydration chamber 2 is equipped with a drying mechanism 5 for dehydrating materials. The dehydration chamber 2 is fixedly connected to a partition 21. The dehydration chamber 2 is divided into a primary drying channel 23 and a secondary drying channel 24 through the partition 21. The primary drying channel 23 is connected to the primary discharge channel 13, and the secondary drying channel 24 is connected to the secondary discharge channel 12.

[0030] The anti-blocking mechanism 4 includes a rotating shaft 41 rotatably disposed inside the screening box 1. Multiple sets of fixing blocks 43 are fixedly connected at equal intervals on the outer side of the rotating shaft 41. Two sets of spring members 44 are provided on one side of each set of fixing blocks 43. A protrusion 45 is fixedly connected to one end of each set of spring members 44.

[0031] Multiple sets of reinforcing seats 46 are rotatably mounted on the rotating shaft 41. The multiple sets of reinforcing seats 46 are alternately arranged with multiple sets of fixing blocks 43. The multiple sets of reinforcing seats 46 are all fixedly connected to the top of the inner cavity of the screening box 1. One end of the rotating shaft 41 passes through the screening box 1 and is driven by the rotary motor 42. One end of the material guide channel 10 is provided with a guide part 11. The alternating arrangement of multiple sets of reinforcing seats 46 and fixing blocks 43 improves the rotational stability of the rotating shaft 41. The spring component 44 is mainly composed of an internal telescopic damping structure and an external spring. It can adjust the position of the protrusion 45 when the protrusion 45 hits the screening cylinder 32, thereby improving the service life of the anti-blocking mechanism 4.

[0032] The screening mechanism 3 includes two sets of bearing seats 31 fixedly connected to the inner cavity of the screening box 1. A screening cylinder 32 is rotatably arranged inside the two sets of bearing seats 31. One end of the screening cylinder 32 is provided with a feed pipe 33 that penetrates the screening box 1, and the other end of the screening cylinder 32 is arranged above the secondary material discharge channel 12. The bearing seats 31 improve the rotational stability of the screening cylinder 32, and the extension line of the screening cylinder 32 intersects the horizontal plane, which facilitates the material to move into the secondary material discharge channel 12 while rolling inside the screening cylinder 32, thereby realizing continuous screening of the material.

[0033] An external gear ring 34 is provided on the outer side of the screening cylinder 32 away from the feed pipe 33. A gear 47 that meshes with the external gear ring 34 is fixedly connected to the end of the rotating shaft 41 near the rotating motor 42. The meshing of the gear 47 with the external gear ring 34 can drive the screening cylinder 32 to rotate, reducing the number of driving devices and lowering the production cost of the equipment.

[0034] The drying mechanism 5 includes a heating chamber 51, a blower assembly 52 is installed inside the heating chamber 51, and two sets of heating wires 54 are installed inside the heating chamber 51. Two sets of air guide pipes 55 are connected to one side of the heating chamber 51. Multiple sets of air outlets 56 are opened on the lower surface of the two sets of air guide pipes 55. The air inside the heating chamber 51 is raised by the heating wires 54, and the blower assembly 52 blows the hot air into the air guide pipes 55. The hot air is then blown into the material in the primary drying channel 23 and the secondary drying channel 24 through the air outlets 56, thereby accelerating the dehydration effect of the material.

[0035] A dustproof net 53 is provided on the side of the heating box 51 opposite to the two sets of air ducts 55. An installation groove 22 for installing the heating box 51 is provided on one side of the dehydration box 2. A gap is provided between the two sets of air ducts 55 for inserting the partition 21. The dustproof net 53 can prevent dust from entering and improve the quality of the material after dehydration. The partition 21 separates the two sets of air ducts 55, which can dry the material in the primary drying channel 23 and the secondary drying channel 24 respectively.

[0036] The lower surface of the dewatering chamber 2 is provided with a primary discharge pipe 6 and a secondary discharge pipe 7. The primary discharge pipe 6 and the secondary discharge pipe 7 are respectively connected to the primary drying channel 23 and the secondary drying channel 24. Multiple sets of dehumidification holes 8 are provided on both sides of the dewatering chamber 2 connected to the mounting groove 22. Under the action of the vibration motor 9 and gravity, the material in the primary drying channel 23 and the secondary drying channel 24 can move slowly, thereby facilitating hot air dewatering while achieving continuous dewatering and improving the dewatering efficiency of the material.

[0037] In use, the material is fed into the screening cylinder 32 through the feed pipe 33, the rotary motor 42 and the vibration motor 9 are started, and the drying mechanism 5 is powered on. The rotary motor 42 drives the rotating shaft 41 to rotate multiple sets of fixed blocks 43, thereby causing the protrusions 45 on the spring 44 to strike the outer wall of the screening cylinder 32. At the same time, the gear 47 meshes with the external gear ring 34. When the screening cylinder 32 rotates, the material tumbles and moves towards the secondary discharge channel 12 under the action of gravity. Smaller materials fall into the guide channel 10 through the screen holes of the screening cylinder 32. The striking of the outer wall of the screening cylinder 32 by the protrusions 45 can prevent the material from clogging the screen holes, thereby improving the screening efficiency of the material.

[0038] Smaller materials are guided by the guide section of the guide channel 10 and fall into the primary drying channel 23 through the primary discharge channel 13. Larger materials in the screening cylinder 32 fall into the secondary discharge channel 12 and enter the secondary drying channel 24 under the action of gravity. Under the action of the vibrating motor 9 and gravity, the materials slowly slide down. The blower assembly 52 blows the air heated by the heating wire 54 into the air guide pipe 55 and blows it onto the materials in the primary drying channel 23 and the secondary drying channel 24 through the air outlet 56, which accelerates the drying effect of the materials. The moisture generated during drying is discharged through the moisture exhaust hole 8, thereby avoiding the moisture backflow and causing the materials to become damp again, which improves the dehydration effect of the materials. The dehydrated materials are collected in stages through the primary discharge pipe 6 and the secondary discharge pipe 7, which improves the dehydration efficiency of the materials.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
