Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a batching chamber with a variable frequency feeding spiral structure. Background Art

[0002] Sintering is an important metallurgical process used to heat powdered raw materials to high temperatures to combine their particles into a mass or block to form a strong finished product. This process is commonly used to produce finished products of metals, ceramics, ores and other materials for subsequent processing or use.

[0003] During the sintering process, powdered raw materials are first mixed and pressed into a green body of the desired shape. These green bodies are then heated in a high-temperature furnace to allow the particles to bond and form a dense block. This process usually includes heating and cooling stages to ensure that the structure and properties of the block are optimized.

[0004] The use of solvents in sintering production plays an important role in its quality and output. At present, sintering has been equipped with lime digesters to enhance the lime digestion effect and improve the quality of sintered minerals. Under the existing equipment, the electronic belt scale has been used for a long time and has relatively poor accuracy, and cannot adjust the feeding situation according to the actual production process.

[0022] 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.

[0023] See also Figure 1-4A batching chamber with a variable frequency feeding spiral structure comprises a batching chamber 1, wherein a feed port is provided at one end of the top surface of the batching chamber 1, and a discharge port is provided at the bottom end of the other side. A variable frequency motor 2 is installed at the middle end of the side surface of the batching chamber 1 where the feed port is provided. The variable frequency motor 2 can adjust the rotation speed of the auger 3, thereby realizing accurate feeding control. The batching chamber 1 is in a truncated cone shape, and the cross-sectional radius gradually increases from the feed port to the discharge port. The end of the truncated cone of the batching chamber 1 is in a cylindrical shape, and the discharge port is provided at the bottom end of the cylindrical area. The output end of the variable frequency motor 2 is connected to the auger 3, and the end of the auger 3 is connected to the end of the truncated cone of the batching chamber 1. The end of the auger 3 is connected to a rotating roller 4, and a blade 5 is arranged on the outer end of the rotating roller 4. A plurality of discharge holes are provided on the truncated cone-shaped bottom surface of the batching chamber 1 for matching the discharge. A second sliding plate 11 corresponding to the discharge holes is provided on the bottom surface of the batching chamber 1. The second sliding plate is provided with holes which are the same as the discharge holes of the batching chamber 1. A second mounting block 9 is connected to the bottom end of the batching chamber 1. A second telescopic rod 10 for controlling the movement of the second mounting block 9 is connected to the side facing the second sliding plate 11. A matching adjustment structure is connected to the top end of the batching chamber 1, and the matching adjustment structure includes a first mounting block 6, a first telescopic rod 7 and a first sliding plate 8.

[0024] Furthermore, the second telescopic rod 10 is fixedly installed with the second mounting block 9 at the middle end away from the variable frequency motor 2, and the end of the second telescopic rod 10 is connected to the terminal end of the second sliding plate 11. Since the second sliding plate 11 is slidably connected to the outer end of the batching chamber 1, the second sliding plate 11 will be pushed to move back and forth when the second telescopic rod 10 is telescoped. At the same time, the second mounting block 9 should be set to ensure that the inclination angle of the second telescopic rod 10 is equal to the taper angle of the outward expansion of the batching chamber 1. The first mounting block 6 is fixedly installed at the top of the batching chamber 1, and the installation position of the first mounting block 6 corresponds to the second mounting block 9. The first telescopic rod 7 is fixedly installed at the middle end of the first mounting block 6 away from the variable frequency motor 2. The output end of the first telescopic rod 7 is connected to the first sliding plate 8. The settings of the first mounting block 6 and the first telescopic rod 7 are symmetrical with the settings of the second mounting block 9 and the second telescopic rod 10, and the first telescopic rod 7 and the second telescopic rod 10 are extended and shortened synchronously.

[0025] Furthermore, the second sliding plate 11 is slidably connected to the batching chamber 1 via a slide groove, the edges of the adjacent end surfaces of the first sliding plate 8 and the second sliding plate 11 extend outward, and a plurality of springs 12 are equidistantly arranged at the extensions of the first sliding plate 8 and the second sliding plate 11. During the retraction process pushed by the first telescopic rod 7 and the second telescopic rod 10, since the spring 12 exists between the first sliding plate 8 and the second sliding plate 11, the tension of the spring 12 can ensure that the top surface of the second sliding plate 11 is in contact with the bottom surface of the batching chamber 1.

[0026] Furthermore, when insufficient feeding occurs, the second telescopic rod 10 is extended to its longest length, and the holes on the surface of the second sliding plate 11 correspond to and overlap with the multiple discharge holes opened on the truncated cone shaped bottom surface of the batching chamber 1. At this time, the material in the batching chamber 1 flows out from the holes, and the amount of discharge is determined by adjusting the overlapping area between the holes on the surface of the second sliding plate 11 and the multiple discharge holes opened on the truncated cone shaped bottom surface of the batching chamber 1. The taper of the surface of the second sliding plate 11 is consistent with the taper of the outer surface of the batching chamber 1. During normal feeding, the second telescopic rod 10 is shortened to its shortest length, and the holes on the surface of the second sliding plate 11 and the multiple discharge holes opened on the truncated cone shaped bottom surface of the batching chamber 1 are completely staggered and circumscribed with each other, and the material inside the batching chamber 1 cannot flow out from the holes.

[0027] Furthermore, the end of the rotating roller 4 is rotatably connected to the middle end of the inner wall of the batching chamber 1, the rotating roller 4 is fixedly connected to the auger 3, the taper of the auger 3 is consistent with the taper of the batching chamber 1, and a plurality of blades 5 are equidistantly arranged at the outer end of the rotating roller 4. By arranging a rotating roller 4 at the discharge port and moving with the auger 3, it is ensured that the discharge port will not be blocked.
