Abstract
Description
Technical Field
[0001] This utility model relates to the rotor of a large vertical shaft impact crusher, specifically improving the dustproof, cooling, and wear-resistant properties of the impeller bearing of the large shaping machine. Background Technology
[0002] Material crushing equipment is divided into layered crushers and impact crushers. Sand making machines, powder making machines, and shaping machines are a type of vertical shaft impact crusher. It uses a high-speed rotating motor pulley to drive the shaping machine rotor to rotate. An impeller that rotates at high speed with the rotor is connected to the upper part of the rotor main shaft. The material entering the shaping machine impeller from the feed bin is scattered onto the material lining around the crushing chamber of the shaping machine by centrifugal force. At the same time, the material cascading from around the overflow port of the shaping machine and the material thrown from the impeller undergo "stone-on-stone" collisions. The material is shaped by the collisions between the material and the material lining of the crushing chamber, the material cascading from around the overflow port of the shaping machine, and the collisions between materials of different particle sizes in the machine chamber.
[0003] For large impact shaping machines, the impeller diameter at the top of the rotor needs to be increased. This increases the rotor's weight significantly, necessitating a higher motor power. The upper and lower bearings on the rotor's main shaft also need to be larger. Due to the increased rotor weight, the high-speed rotation of the bearings generates considerable heat, requiring a change from grease lubrication to thin oil lubrication to ensure proper bearing operation. This necessitates consideration of bearing dust prevention and cooling. Furthermore, the increased impeller diameter also increases the surface area of the impeller, necessitating consideration of surface wear resistance. Summary of the Invention
[0004] Therefore, this utility model designs a dustproof, cooling, and wear-resistant structure for the impeller bearing of a large forming machine, which greatly extends the service life of the rotor impeller of the large forming machine and reduces the labor intensity of workers.
[0005] The objective of this utility model is achieved through the following means:
[0006] A dustproof, cooling, and wear-resistant structure for a large forming machine impeller bearing includes an impeller mounted on an impeller bearing. An impeller retaining ring is provided around the impeller bearing, and a bearing dustproof and cooling fan is provided on the outer surface of the impeller bearing. The bearing dustproof and cooling fan rotates with the impeller bearing within the cavity enclosed by the impeller retaining ring. A baffle plate is placed on the impeller.
[0007] The dustproof, cooling, and wear-resistant structure of the impeller bearing of the aforementioned large forming machine includes baffles that are evenly distributed on the upper and lower surfaces of the impeller bottom.
[0008] The dustproof, cooling, and wear-resistant structure of the impeller bearing of the above-mentioned large forming machine has four baffles on the upper and lower surfaces of the impeller, which are evenly installed on the corresponding impellers by baffle fixing bolts.
[0009] The aforementioned large forming machine impeller bearing dustproof, cooling, and wear-resistant structure comprises several dustproof and cooling fan blades that are evenly distributed radially on the outer surface of the impeller bearing.
[0010] The dustproof, cooling, and wear-resistant structure of the impeller bearing of the aforementioned large forming machine has a dustproof and cooling fan blade that is inclined, i.e., the angle between the dustproof and cooling fan blade and the bearing axis is an acute or obtuse angle.
[0011] The dustproof, cooling, and wear-resistant structure of the impeller bearing of the aforementioned large forming machine includes baffles on the upper and lower surfaces of the impeller that are either correspondingly or staggered.
[0012] Compared with the prior art, the present invention has the following technical effects:
[0013] This utility model patent, by increasing the upper and lower surfaces of the impeller of a large-scale shaping machine, adds an impeller retaining ring and a retaining plate to the impeller. This significantly extends the service life of the rotor impeller of the large-scale shaping machine and reduces the labor intensity of workers.

[0022] The following is in conjunction with the appendix Figures 1-4 The structure and working process of this utility model will be described in detail.
[0023] Combination Figures 1-4 This utility model discloses a dustproof, cooling, and wear-resistant structure for an impeller bearing of a large forming machine. The structure includes an impeller 1 mounted on an impeller bearing 6. An impeller retaining ring 5 is fitted around the impeller bearing. A bearing dustproof and cooling fan 4 is disposed on the outer surface of the impeller bearing, rotating with the impeller bearing within the cavity enclosed by the impeller retaining ring. A baffle plate 2 is disposed on the bottom of the impeller, evenly distributed on the upper and lower surfaces of the impeller bottom.
[0024] The impeller 1 described in this utility model is a material distribution device that rotates at high speed with the rotor of a large shaping machine. The crushed raw material passes through the discharge channel on the impeller and, under the action of centrifugal force, is thrown onto the material lining around the crushing chamber and crushed. As the model of the shaping machine increases, the external dimensions of the impeller also increase, making it possible to add a baffle plate 2, an impeller baffle ring 5, and a bearing dustproof and cooling fan blade 4.
[0025] The baffle plate 2 described in this invention is a replaceable baffle device that is added to the upper and lower surfaces of the impeller 1 and fixed with baffle plate bolts. The baffle plate 2 rotates at high speed with the impeller 1, preventing material from impacting the upper and lower surfaces of the impeller 1 and reducing wear on these surfaces. The baffle plate 2 is generally made of high-wear-resistant high-chromium cast iron. Four baffle plates are located on the upper and lower surfaces of the impeller, evenly mounted on the corresponding impeller surfaces using baffle plate fixing bolts.
[0026] The dustproof, cooling, and wear-resistant structure of the impeller bearing for the large forming machine described in this utility model includes four baffle plates evenly mounted on the upper and lower surfaces of the impeller via baffle plate fixing bolts 3. The impeller on the upper and lower surfaces is as follows: Figure 3 As shown in the diagram, a long baffle fixing bolt passes sequentially through the lower baffle plate, the impeller, and the upper impeller baffle plate, fixing the upper and lower baffle plates of the impeller to the impeller. Alternatively, as shown... Figure 2 As shown, the baffles on the upper and lower surfaces of the impeller are arranged alternately.
[0027] The dustproof, cooling, and wear-resistant structure of the impeller bearing of the large shaping machine described in this utility model consists of several dustproof and cooling fan blades that are evenly distributed radially on the outer surface of the impeller bearing.
[0028] The dustproof, cooling, and wear-resistant structure for the impeller bearing of the large shaping machine described in this utility model features an inclined dustproof and cooling fan blade, meaning the angle between the dustproof and cooling fan blade and the bearing axis is either acute or obtuse. Figure 4 As shown.
[0029] The material plate fixing bolt 3 described in this utility model is a fastening structure that fixes the baffle plate 2 to the upper and lower surfaces of the impeller 1. As the baffle plate 2 wears, the impeller baffle plate 2 can be easily replaced by disassembling the baffle plate fixing bolt 3.
[0030] The bearing dustproof and cooling fan blade 4 described in this utility model is a rotating fan blade installed on the rotor main shaft at the lower part of the impeller of a large forming machine. It rotates at high speed with the main shaft, and the wind force generated can play a role in cooling the upper bearing.
[0031] The impeller baffle ring 5 described in this utility model is an annular baffle structure set at the lower part of the impeller of a large forming machine. It can block the impact of materials on the main shaft and protect the main shaft. At the same time, the annular structure it forms can also concentrate the wind force generated by the bearing dustproof and cooling fan 4, and force the bearing above it to be air-cooled.
[0032] This invention redesigns the impeller on the rotor of a large shaping machine by adding an impeller retaining ring to the rotor main shaft at the lower part of the impeller. At the same time, a bearing dustproof and cooling fan that rotates at high speed with the main shaft is added inside the retaining ring. The wind force generated by the high-speed rotating bearing dustproof and cooling fan partially cools the bearing above it.
[0033] On the upper and lower surfaces of the impeller on the rotor of a large forming machine, baffles made of wear-resistant material are added and fixed by baffle bolts. As the impeller rotates at high speed, the baffles can block and reduce the material from impacting the upper and lower surfaces of the impeller, thereby reducing the wear on the upper and lower surfaces of the impeller and extending the service life of the impeller.
[0034] The dustproof, cooling, and wear-resistant structure of the impeller bearing of the large forming machine described in this utility model features staggered baffles on the upper and lower surfaces of the impeller, which improves the overall strength of the impeller.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
