Description

Technical Field

[0001] This utility model relates to the field of iron concentrate grading and storage technology, specifically, to an iron concentrate grading and storage device. Background Technology

[0002] Iron concentrate is an iron-containing mineral powder that has undergone mineral processing. It is mainly composed of iron(III) oxide and ferrous oxide. It has the characteristics of high iron content, high purity and high density, and is widely used in the fields of iron and steel, metallurgy and manufacturing. Storage equipment is used when storing iron concentrate.

[0003] Current iron concentrate storage equipment typically uses storage tanks to store iron concentrate. Iron concentrate of various particle sizes is stored mixed inside the tanks, resulting in poor storage efficiency and affecting subsequent retrieval of the iron concentrate.

[0004] The existing graded storage method usually involves setting up multiple sieves inside the storage tank to separate iron concentrate of different particle densities through gravity settling and sieving, so as to achieve graded storage of iron concentrate of different particle densities.

[0005] However, the above-mentioned graded storage method only uses gravity sedimentation to screen iron concentrate with different particle densities, resulting in a slow separation speed and poor working efficiency. Therefore, we propose an iron concentrate graded storage device. Utility Model Content

[0006] This invention proposes an iron concentrate grading and storage device to solve the problem that the existing technology of sieving iron concentrate of different particle densities by gravity sedimentation results in slow separation speed and poor working efficiency.

[0007] The technical solution of this utility model is as follows: A grading and storage device for iron concentrate includes a storage tank, grading sieves, a mounting base, a stirring shaft, stirring components, screw rods, and a scraping mechanism. Multiple grading sieves are vertically arranged inside the storage tank. A feed hopper is connected to the upper side of the storage tank via a feed pipe. The storage tank is rotatably mounted on the upper side of the mounting base, and a base support is mounted on the lower side of the mounting base. A driving component for driving the storage tank to rotate is provided on the mounting base. The stirring shaft is rotatably mounted on the inner top wall of the storage tank. A driving component for driving the stirring shaft to rotate is provided on the upper side of the storage tank. Multiple sets of stirring components are vertically mounted on the stirring shaft. The stirring components rotate with the stirring shaft and are respectively positioned above the corresponding grading sieves. The stirring components are used to stir the iron concentrate on the upper side of the grading sieves. Multiple screw rods are rotatably mounted on the stirring shaft via a scraping mechanism. A driving component for driving the screw rods to rotate is provided on the scraping mechanism. The screw rods can rotate synchronously with the stirring shaft via the scraping mechanism while rotating on their own axis.

[0008] The stirring assembly includes a main stirring rod mounted on the outside of the stirring shaft and rotating with the stirring shaft, and an auxiliary stirring rod mounted on the main stirring rod and rotating synchronously with the main stirring rod.

[0009] The scraping mechanism includes a plurality of scraping frames mounted on the stirring shaft, the scraping frames rotating with the stirring shaft, and a scraper installed in the lower part inside the scraping frame and rotating synchronously with the scraping frame.

[0010] To ensure the scraping effect of the scraper on the iron concentrate, the scraper is shaped like an isosceles triangle, with the lower side of the scraper abutting against the upper side of the grading screen plate.

[0011] In order to support the storage tank during rotation and ensure its stability, a plurality of movable support wheels are installed on the lower side of the storage tank, and the plurality of movable support wheels are arranged in a ring on the lower side of the storage tank.

[0012] In order to protect the drive component inside the mounting base and reduce the impact of iron concentrate in the environment on the drive component, a support blocking ring is installed on the lower side of the storage tank, and multiple balls are rotatably arranged on the lower side of the support blocking ring.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] In this invention, the rotation of the storage tank, combined with the stirring shaft, drives the stirring assembly to rotate inside the storage tank, thereby achieving bidirectional stirring of the iron concentrate inside the storage tank. This accelerates the separation speed of the grading sieve plate for iron concentrate with different particle densities and improves work efficiency.

[0015] In this invention, a scraping mechanism can scrape the iron concentrate powder placed on the grading sieve plate, thereby improving the screening and grading of the iron concentrate powder. The spiral rod can drive the iron concentrate powder on the grading sieve plate to move back and forth, reducing the probability of iron concentrate powder accumulating in one place, thus enhancing the grading effect of iron concentrate powder.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-4As shown, this embodiment proposes an iron concentrate grading and storage device, including a storage tank 1, a grading sieve plate 2, a mounting base 3, a stirring shaft 4, a stirring assembly, a screw rod, and a scraping mechanism. The upper side of the storage tank 1 is connected to a feed hopper 9 through a feed pipe 8. Compared with the prior art, in this embodiment, the rotation of the storage tank 1, combined with the stirring shaft 4 driving the stirring assembly to rotate inside the storage tank 1, achieves bidirectional stirring of the iron concentrate inside the storage tank 1, thereby accelerating the separation speed of iron concentrate with different particle densities on the grading sieve plate 2 and improving working efficiency. The scraping mechanism can scrape the iron concentrate on the grading sieve plate 2, thereby better screening and grading the iron concentrate. The screw rod 5 can drive the iron concentrate on the grading sieve plate 2 to move back and forth, reducing the probability of iron concentrate accumulating in one place, thereby enhancing the grading effect of iron concentrate.

[0026] like Figure 2 As shown, the storage tank 1 is rotatably mounted on the upper side of the mounting base 3. The mounting base 3 is equipped with a driving component for driving the storage tank 1 to rotate. Multiple movable support wheels 6 are mounted on the lower side of the storage tank 1, arranged in a ring. These wheels provide support during the rotation of the storage tank 1, ensuring its stability. A support blocking ring 7 is also mounted on the lower side of the storage tank 1. Multiple ball bearings are rotatably mounted on the lower side of the support blocking ring 7. This ring blocks airborne iron powder, reducing its impact on the storage tank. The influence of the internal drive component of the mounting base 3 is that the stirring shaft 4 is rotatably mounted on the inner top wall of the storage tank 1. The upper side of the storage tank 1 is provided with a drive component for driving the stirring shaft 4 to rotate. Multiple sets of stirring components are vertically mounted on the stirring shaft 4. The multiple sets of stirring components are respectively located above the corresponding grading sieve plate 2. The stirring components include a main stirring rod 101 and an auxiliary stirring rod 102. The storage tank 1 can rotate under the drive component. The rotation of the storage tank 1, in conjunction with the rotation of the stirring components, realizes bidirectional stirring of the iron concentrate inside the storage tank, thereby accelerating the filtration and separation speed of the iron concentrate by the grading sieve plate 2.

[0027] like Figure 3 and Figure 4 As shown, the stirring shaft 4 is rotatably mounted with multiple spiral rods 5 via a scraping mechanism. The scraping mechanism is equipped with a driving component for driving the spiral rods 5 to rotate. The scraping mechanism includes a scraping frame 201 and a scraper 202. The scraper 202 is shaped like an isosceles concave slab, with its lower side positioned above the grading sieve plate 2. The design of the scraper 202 enhances its scraping effect on the iron concentrate. In this embodiment, the driving components are all reversible motors. The scraping mechanism can scrape the iron concentrate accumulated on the grading sieve plate 2, and the spiral rods 5 can drive the iron concentrate on the grading sieve plate 2 to move back and forth, reducing the probability of iron concentrate accumulating.

[0028] Working principle;

[0029] Workers pour the iron concentrate to be stored into the feed hopper. The iron concentrate enters the storage tank 1 through the feed hopper and feed pipe. After pouring, the forward and reverse motors located on the mounting base 3 and storage tank 1 are started. The forward and reverse motors drive the storage tank 1 and the stirring shaft 4 to rotate respectively. The stirring shaft 4 drives the stirring assembly, scraping mechanism and screw rod 5 to rotate synchronously. The main stirring rod 101 and auxiliary stirring rod 102 inside the stirring assembly agitate the iron concentrate entering the storage tank 1. The scraping frame 201 and scraper 202 inside the scraping mechanism scrape the iron concentrate on the grading screen plate 2. While the rotary rod 5 rotates synchronously with the stirring shaft 4, the forward and reverse motor located on the scraping mechanism is started (because the forward and reverse motor is equipped with a protective cover on the outside, the iron concentrate will not affect the normal use of the forward and reverse motor). The forward and reverse motor drives the screw rod 5 to rotate, and the screw rod 5 drives the iron concentrate on the grading sieve plate 2 to move back and forth. While stirring the iron concentrate, the iron concentrate on the grading sieve plate 2 moves back and forth. During the stirring process, the iron concentrate can fall through the screening holes opened on the grading sieve plate 2 to the inner bottom wall of the grading sieve plate 2 and the storage tank 1 below, thereby realizing the rapid grading and storage of iron concentrate.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
