Description

Technical Field

[0001] This utility model belongs to the field of coal processing and relates to a coal mixing machine that can fully mix different coal qualities online. Background Technology

[0002] In the field of coal processing and utilization, coal mixers, as a key piece of equipment, are widely used for online mixing of different coal qualities to meet the coal quality characteristics requirements of various industrial applications. However, with the diversified development of the coal market, the types and characteristics of coal are becoming increasingly complex, placing higher demands on the mixing effect, adaptability, and operating efficiency of coal mixers.

[0003] Traditional coal mixers often face problems such as uneven mixing, low efficiency, and difficulty adapting to high-moisture or viscous coal when processing different coal qualities. Specifically, when processing coal with high moisture content or high viscosity, the mixing body of traditional coal mixers is prone to reduced mixing efficiency due to material adhesion, and may even lead to equipment blockage, affecting the continuous operation of the production line. In addition, the mixing mechanism of traditional coal mixers has a simple design, making it difficult to flexibly adjust according to changes in coal quality characteristics, thus limiting its mixing effect and application range.

[0004] While existing technologies offer some improvements to address the aforementioned issues, most focus on localized optimization of the mixing mechanism or upgrades to the control system, failing to fundamentally resolve the adaptability and mixing effectiveness of coal mixers when handling different coal qualities. Therefore, developing a coal mixer capable of efficiently processing different coal qualities online, with strong adaptability and excellent mixing performance, has become a pressing technical challenge in the current coal processing field.

Detailed Implementation

[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The following is in conjunction with the appendix Figure 1 To be continued Figure 9 The present invention will be described in detail with reference to specific embodiments:

[0032] A coal blender for online processing of different coal qualities, reference Figures 1-9It includes a support frame 1, a coal mixing chamber 2 installed on the support frame 1, a feed hopper 3 at the top of the coal mixing chamber 2, a discharge port 4 at the bottom of the coal mixing chamber 2, and a stirring mechanism 5 inside the coal mixing chamber 2.

[0033] The stirring mechanism 5 includes a flange 501, a stirring shaft 502, multiple mounting rods 503, and a stirring body 504. The stirring shaft 502 is fixed to the upper surface of the flange 501, the multiple mounting rods 503 are fixed to the side wall of the stirring shaft 502, and the stirring body 504 is mounted on the surface of the mounting rods 503. The stirring body 504 is a plate-shaped or cylindrical structure.

[0034] It also includes a motor 6, with a drive wheel mounted on the output shaft of the motor 6, and a driven wheel fixedly connected to the bottom of the flange 501. The drive wheel and the driven wheel are connected to the motor 6 via a belt drive.

[0035] It also includes a control terminal, which controls the speed of motor 6.

[0036] The mounting rod 503 includes multiple first mounting rods 5031 and multiple second mounting rods 5032. The first mounting rods 5031 and the second mounting rods 5032 extend laterally through the stirring shaft 502. The plumb plane of the first mounting rod 5031 is perpendicular to the plumb plane of the second mounting rod 5032. The first mounting rods 5031 and the second mounting rods 5032 are arranged sequentially from top to bottom, with their lengths gradually increasing.

[0037] One end of the stirring body 504 is fixed to the outer wall of the outer end of the first mounting rod 5031, and the other end is fixed to the outer wall of the outer end of the second mounting rod 5032. The stirring bodies 504 are symmetrically arranged on both sides of the first mounting rod 5031 or the second mounting rod 5032. Up to two stirring bodies 504 are fixed on the same side of the first mounting rod 5031 or the second mounting rod 5032, and the two stirring bodies 504 extend in opposite directions.

[0038] Specifically, the outer wall of the mounting rod 503 is equipped with three sets of first mounting rods 5031 and two sets of second mounting rods 5032. The top mounting rod 503 is a second mounting rod 5032, with a stirring body 504 symmetrically fixed to both sides, and one stirring body 504 on each side. The mounting rods 503 are installed downwards sequentially, and the bottom mounting rod 503 is a first mounting rod 5031, with a stirring body 504 symmetrically fixed to both sides, and one stirring body 504 on each side. The two ends of the mounting rod 503 between the bottom and top ends are... A stirring body 504 is symmetrically fixed to the side. There are two stirring bodies 504 on the same side. One of the two stirring bodies 504 extends upward until it is fixed to another mounting rod 503. The stirring body 504 with the same inclination direction as the stirring body 504 forms a positive spiral around the stirring shaft 505. The other stirring body 504 extends downward until it is fixed to another mounting rod 503. The stirring body 504 with the same inclination direction as the stirring body 504 forms a negative spiral around the stirring shaft 505.

[0039] The upward-extending agitator forms a forward spiral that lifts the coal from the bottom of the mixing chamber during mixing. This lifting action helps bring the insufficiently mixed coal at the bottom to the top, allowing for more thorough contact and mixing with the coal at the top. Conversely, the downward-extending agitator forms a reverse spiral that pushes the coal downwards from the top. This pushing action helps bring the coal from the top to the bottom, further mixing with the coal at the bottom. The combined action of the forward and reverse spirals creates an up-and-down circulation of coal within the mixing chamber, greatly enhancing the mixing effect and ensuring that different coal types are thoroughly and evenly mixed together.

[0040] Example 1

[0041] refer to Figures 2-5 The mixing element 504 features a plate-like structure, designed for mixing materials with a moisture content of less than 10%. This plate-like structure provides a larger contact area during mixing, facilitating thorough mixing of materials. Furthermore, for low-moisture materials, the plate-like structure minimizes material adhesion, maintaining mixing efficiency.

[0042] The plate-shaped mixing body 504 is a mixing plate 5041. The inner and outer edges of the mixing plate 5041 are rounded. The rounded edges help reduce the jamming and wear of materials during the mixing process, and also help the materials flow smoothly on the surface of the mixing plate, thus improving the mixing effect.

[0043] One end of the stirring plate 5041 is fixed to the outer wall of the outer end of the first mounting rod 5031, and the stirring plate 5041 is fixed to the outer wall of the outer end of the second mounting rod 5032.

[0044] The mixing plate 5041 has a gap in the middle, which divides the mixing plate 5041 into two sections. One section is fixed to the outer wall of the outer end of the first mounting rod 5031, and the other section is fixed to the outer wall of the outer end of the second mounting rod 5032.

[0045] During the mixing process, the coal is mixed under the action of the mixing plate 5041, and some of the coal falls through the gaps on the mixing plate 5041, forming a circulating flow and further enhancing the mixing effect. The existence of the gaps not only provides a falling channel for the coal during the mixing process, but also helps to control the amount of coal discharged from the outlet.

[0046] The control unit can adjust the stirring speed of the mixing plate 5041 and the coal falling speed, thereby precisely controlling the coal output from the discharge port in conjunction with the interval. This design allows the coal mixer to flexibly adjust the output according to actual needs, improving production efficiency.

[0047] The working principle of Example 1 is as follows: the coal mixer uses a plate-shaped mixing plate 5041 as the mixing body 504 to mix materials with a moisture content of less than 10%. During operation, the material enters the mixing chamber 2 from the feed hopper 3. The motor 6 drives the mixing shaft 502 to rotate via belt drive, which in turn drives the mixing plate 5041 to rotate. The inner and outer edges of the mixing plate 5041 are designed with rounded arcs, which reduces material jamming and wear during the mixing process, while providing a larger contact area to facilitate thorough mixing of materials. The interval in the middle of the mixing plate 5041 divides the mixing plate into two sections, which are respectively fixed to the first mounting rod 5031 and the second mounting rod 5032. During the mixing process, the coal is mixed under the action of the mixing plate 5041, and some coal falls through the interval on the mixing plate, forming a circulating flow and further enhancing the mixing effect. The control end can adjust the mixing speed of the mixing plate 5041 and the coal falling speed according to actual needs, thereby precisely controlling the coal output of the discharge port 4 and improving production efficiency.

[0048] Example 2

[0049] refer to Figures 6-9 The mixing element 504 features a cylindrical structure, designed for mixing materials with a moisture content greater than 10%. During mixing, the cylindrical structure provides a curved contact surface with the material. Compared to a plate-like structure, this curved surface more effectively reduces the adhesion of sticky materials to the mixing element, thereby shortening the contact time between the material and the mixing column, reducing stickiness caused by moisture, and ensuring smooth mixing.

[0050] The mixing body 504 includes at least three mixing columns 5042. This design helps to form a stable mixing flow field during the mixing process, so that the materials are uniformly mixed in the mixing chamber.

[0051] One end of the stirring column 5042 is fixed to the outer wall of the outer end of the first mounting rod 5031, and the stirring column 5042 is fixed to the outer wall of the outer end of the second mounting rod 5032.

[0052] A mounting plate 505 is horizontally fixed to the outer wall of the mounting rod 503 at the bottom end, and a baffle 506 is fixedly fixed to the surface of the mounting plate 505 at an angle. This angled design helps guide the flow direction of materials during the mixing process, enhancing the mixing effect. At the same time, the baffle can also prevent materials from accumulating at the bottom of the mixing chamber to a certain extent, improving the mixing efficiency.

[0053] The stirring column 5042, together with the mounting plate 505 and the baffle 506, forms a stirring system for high-moisture materials. This system reduces material adhesion through arc-shaped surface contact, promotes material mixing using centrifugal force, and guides material flow through the baffle, achieving efficient mixing of high-moisture materials.

[0054] The working principle of Example 2 is as follows: the coal mixer uses a cylindrical stirring column 5042 as the stirring body 504 to mix materials with a moisture content greater than 10%. During operation, the material enters the coal mixing chamber 2 from the feed hopper 3. The motor 6 drives the stirring shaft 502 to rotate via belt drive, which in turn drives the stirring column 5042 to rotate. The contact surface between the stirring column 5042 and the material is an arc surface, which effectively reduces the adhesion of sticky and wet materials on the stirring column, shortens the contact time between the material and the stirring column, and reduces the stickiness problem caused by moisture. At least three stirring columns 5042 are arranged to form a stable stirring flow field, so that the material is uniformly mixed in the coal mixing chamber. A mounting plate 505 is horizontally fixed to the outer wall of the mounting rod 503 at the bottom end. A baffle 506 is fixedly fixed to the surface of the mounting plate 505 at an angle. This design helps to guide the flow direction of the material, enhance the mixing effect of the material, and prevent the material from accumulating at the bottom of the coal mixing chamber. The mixing column 5042, together with the mounting plate 505 and the baffle 506, achieves efficient mixing of high-moisture materials, ensuring the stable operation and efficient production of the coal mixer.

[0055] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
