Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, specifically to a gear ring for an ultra-micro pulverizer and an ultra-micro pulverizer. Background Technology

[0002] The grinding chamber of the ultrafine pulverizer is equipped with a toothed ring, a grinding disc, and other components. Several hammers are installed on the circumference of the grinding disc near the toothed ring. The hammers crush the material by striking it at high speed, and the high-speed rotation of the hammers throws the material towards the toothed ring. The high-speed airflow impacts the material, causing strong collisions and friction between the materials, thereby achieving the purpose of fine crushing.

[0003] The toothed ring is a crucial component of an ultrafine pulverizer, primarily used for crushing materials. The pulverizer's efficiency is directly related to the toothed ring. Widely used toothed rings on the market have multiple tooth-like structures arranged circumferentially on their inner side. These tooth-like structures are usually fitted with a flat alloy as a wear-resistant layer to improve wear resistance. However, in actual use, it has been found that the center of the flat alloy experiences more impact wear than the sides. Therefore, the existing shape of the flat alloy is not fully utilized, resulting in some waste. Utility Model Content

[0004] In view of this, the present invention provides a toothed ring for an ultra-fine pulverizer and an ultra-fine pulverizer, aiming to improve the utilization rate of the wear-resistant layer and reduce waste.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is as follows:

[0006] A gear ring for an ultrafine pulverizer includes a gear ring body, on the inner side of which a plurality of tooth-like structures are arranged circumferentially, and also includes pulverizing blades, which are mounted on the tooth-like structures; the pulverizing blades include core area pulverizing blades mounted in the middle of the tooth-like structures and non-core area pulverizing blades mounted at both ends of the tooth-like structures; and the thickness of the core area pulverizing blades is greater than the thickness of the non-core area pulverizing blades.

[0007] In some alternative embodiments, the core area crushing blades have at least two shapes; the core area crushing blades mounted on adjacent toothed structures have different shapes.

[0008] In some optional embodiments, the core area crushing tool includes a tip portion and a handle portion; the tip portion has multiple tips, and there is a gap between adjacent tips; the handle portion has multiple grooves and / or raised ridges arranged side by side.

[0009] In some alternative embodiments, the cross-section of the groove and / or the raised rib is tapered.

[0010] In some alternative implementations, the gaps on the tips of the core area crushing blades on adjacent toothed structures are staggered in the working direction.

[0011] An ultrafine pulverizer includes a gear ring as described above.

[0012] In summary, compared with the prior art, this utility model has the following advantages and beneficial effects: Since the impact and wear on the toothed ring mainly occur in the middle of the toothed structure, this utility model installs a thicker core area crushing blade in the middle of the toothed structure to cope with high-intensity impacts, and installs thinner non-core area crushing blades at both ends of the toothed structure to save materials. The crushing blade formed by the combination of the core area crushing blade and the non-core area crushing blades on both sides is used to replace the existing planar alloy wear-resistant layer, and its installation method is the same as that of the existing planar alloy wear-resistant layer. The crushing blade described in this utility model has a more targeted structure than the original planar alloy wear-resistant layer, which can make full use of materials and reduce waste while ensuring the crushing effect.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0018] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number, while "above," "below," "within," etc. are understood to include the stated number. If terms such as "first," "second," etc., are used only to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features, or implicitly specifying the order of the indicated technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] like Figure 1 and Figure 2 As shown, the toothed ring of the ultrafine pulverizer of this utility model includes a toothed ring body 1. Multiple tooth-like structures 2 are neatly arranged circumferentially on the inner side of the toothed ring body 1. These tooth-like structures 2 mainly cooperate with the hammer to perform pulverization operations on materials.

[0022] This invention aims to improve the utilization rate of the wear-resistant layer, such as... Figure 2 As shown, it also includes multiple crushing blades, which are mounted on the toothed structure 2, with one crushing blade mounted on each toothed structure 2. The crushing blades include a core area crushing blade 3 mounted in the middle of the toothed structure 2 and non-core area crushing blades 4 mounted at both ends of the toothed structure 2, and the thickness of the core area crushing blade 3 is greater than the thickness of the non-core area crushing blades 4.

[0023] Since the impact and wear on the toothed ring mainly occur in the middle of the toothed structure 2, this invention installs a thicker core area crushing blade 3 in the middle of the toothed structure 2 to cope with high-intensity impacts, and thinner non-core area crushing blades 4 at both ends of the toothed structure 2 to save materials. The crushing blade formed by the combination of the core area crushing blade 3 and the non-core area crushing blades 4 on both sides replaces the existing planar alloy wear-resistant layer. Its installation method is the same as that of the existing planar alloy wear-resistant layer. The crushing blade can still be made of alloy materials, such as tungsten-cobalt alloys, high-chromium alloys, etc. Compared with the original planar alloy wear-resistant layer, the crushing blade described in this invention has a more targeted structure, which can make full use of materials and reduce waste while ensuring the crushing effect.

[0024] To improve crushing efficiency, as an optional implementation, the core area crushing blades 3 have at least two shapes, and the core area crushing blades 3 installed on adjacent toothed structures 2 have different shapes. The advantage of this design is that the combination of core area crushing blades 3 with different shapes can cover a wider crushing angle, covering particles at various angles within the gap between the hammer and the toothed ring. This increases the probability of material being crushed, making it easier to break down the material, reducing secondary crushing, and thus improving crushing efficiency.

[0025] As an optional implementation method, such as Figure 3 As shown, the core area crushing blade 3 may include a blade tip 31 and a blade handle 32. The blade handle 32 is located on the toothed structure 2, and the blade tip 31 is located at the edge of the toothed structure 2. The blade tip 31 has multiple blade tips 311, and gaps 312 are formed between adjacent blade tips to allow particulate material to pass through. The blade handle 32 has multiple parallel grooves and / or raised ribs 321, which can form sharp corners for crushing materials. Preferably, the cross-section of these grooves and / or raised ribs 321 is tapered to make the sharp corners even sharper.

[0026] The main difference between core area crushing blades 3 of different shapes is the number of blade tips and the location of the slits 312. For example, some core area crushing blades 3 have four blade tips 311 and three slits 312, while others have five blade tips 311 and four slits 312.

[0027] When the particulate material in the gap between the hammer and the toothed ring impacts the core crushing blade 3, some of the particulate material will collide with and be crushed by the blade tip 311; the other part of the particulate material will pass through the gap 312 between the blade tips 311 and maintain a high speed to impact the next core crushing blade 3, thus ensuring the impact force. Therefore, as Figure 2 As shown, it is also possible to design the gaps 312 on the tip 31 of the core area crushing blade 3 on the adjacent toothed structure 2 to be staggered in the working direction, so as to ensure that each particle flying towards the core area crushing blade 3 can be powerfully impacted by the core area crushing blade 3; some particles will also collide with and be crushed by the sharp corners formed by the grooves and / or protruding ribs 321 on the handle 32. Due to the position and angle relationship, the sharp corners of the handle 32 do not need to be provided with gaps.

[0028] The shape of the non-core area crushing blade 4 can be designed as a flat strip similar to the shape of the existing planar alloy wear-resistant layer, only with a smaller thickness.

[0029] This utility model also introduces an ultrafine pulverizer with a toothed ring as described above. Using the toothed ring in the ultrafine pulverizer not only optimizes the utilization efficiency of the wear-resistant layer material but also improves pulverization efficiency. Comparative testing under the same operating conditions shows a nearly 8% increase in output, a significant improvement, while saving approximately 7% in electricity consumption. This reduces the load on the power grid, minimizes unnecessary expenses, and increases profits.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
