Description

Technical Field

[0001] This utility model relates to the field of slag powder processing technology, specifically a double-layer combined slag powder grinding wheel. Background Technology

[0002] Slag is a byproduct of blast furnace ironmaking. Slag plays an important role in industrial production, especially in some large factories. Slag is refined and processed into slag cement, slag powder, slag silicate cement, slag wool, blast furnace slag, slag powder, copper slag, and slag vertical mills, saving energy consumption.

[0003] Chinese patent CN215996816U discloses a grinding device for a slag powder classifier, including a classifier, a connecting pipe, and a grinding device. This patent relates to the field of slag powder grinding technology and has the following beneficial effects: it is equipped with a grinding structure to fully grind the slag powder; it also has a sliding structure to ensure that the slag powder is ground in a closed space and will not splash out, facilitating internal maintenance and cleaning; and it also has a conveying structure that can drive the conveyor blades to rotate via a motor, conveying all the ground slag powder out, which can greatly reduce the residue of slag powder.

[0004] In actual use, the grinding device of the above-mentioned patent has poor wear resistance, and the smooth surface of the grinding wheel is easily pressed into irregular pits. This not only reduces the grinding efficiency and increases the grinding cycle, leading to increased energy consumption, but also causes uneven particle size of slag powder, further increasing the energy consumption required for screening and repeated grinding of slag powder at the end of the process. Therefore, it does not meet the existing needs. In response, we have proposed a double-layer combined slag powder grinding wheel. Utility Model Content

[0005] The purpose of this invention is to provide a double-layer combined slag powder grinding wheel, which solves the problem mentioned in the background art that the smooth surface of the grinding wheel is easily pressed into irregular pits during actual use, reducing grinding efficiency and having poor wear resistance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-layer combined slag powder grinding wheel, comprising an outer wear-resistant liner and an inner base wheel, wherein the inner base wheel is inserted into the outer wear-resistant liner and engages with it, and the outer surface of the outer wear-resistant liner is provided with an integrally formed concave annular groove, and the interior of the concave annular groove is provided with cross-patterns.

[0007] The outer surface of the inner base wheel is provided with an integrally formed cooling channel, which is sealed to the inner wall of the outer wear-resistant liner.

[0008] Preferably, the cross-pattern surrounding the surface of the outer wear-resistant liner is integrally formed with the outer wear-resistant liner.

[0009] Preferably, the outer wear-resistant liner has an integrally formed inner combination groove inside, and the inner base wheel is embedded in the inner combination groove and fitted with the outer wear-resistant liner.

[0010] Preferably, a flange is welded to the outside of the inner base wheel, and locking bolts are surrounding the flange to fix the flange and the outer wear-resistant liner.

[0011] Preferably, the flange is provided with heat sinks on its exterior, the cooling channel extends into the heat sink and communicates with the heat sink, and the interior of the cooling channel is provided with coolant.

[0012] Preferably, a drive shaft runs through the center of the inner substrate wheel, and the surface of the drive shaft is provided with an integrally formed keyway. The drive shaft is connected to the motor shaft of the grinding motor through the keyway.

[0013] Preferably, a positioning block is welded to the outer surface of the inner base wheel, and an integrally formed positioning slot is provided on the inner wall of the inner combination groove. The positioning block is inserted into the positioning slot and engages with the outer wear-resistant liner.

[0014] Preferably, the inner base wheel has an integrally formed positioning port in the middle, the positioning port is inserted into the outer wear-resistant liner and is slidably connected to the outer wear-resistant liner, and the outer wear-resistant liner has an inner limiting block inside, the inner limiting block is embedded in the positioning insert and is slidably connected to the positioning insert.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The outer wear-resistant liner of this utility model adopts a design with concave annular grooves and cross-patterns on its outer surface. After grinding, the slag powder accumulates inside the concave annular grooves, forming a smooth surface similar to the cross-patterns. The grinding contact area with the slag powder is still relatively large. However, due to the pre-set cross-patterns, the surface of the outer wear-resistant liner has relatively few pits that are easily damaged by the slag powder. After grinding, the slag powder itself is automatically filled in. This not only facilitates the uniform grinding of the slag powder, thereby shortening the grinding cycle, but also improves the wear resistance of the outer wear-resistant liner surface, maintains a high grinding efficiency, and effectively reduces the power consumption required for grinding, which is beneficial for energy saving.

[0017] 2. The combination of the outer wear-resistant liner and the inner base wheel of this utility model allows for modular installation. Maintenance can be performed on the outer wear-resistant liner and the inner base wheel separately. The inner base wheel and positioning insert are installed using inner limit blocks and positioning slots to maintain stable position. Simultaneously, the spiral cooling channels on the surface of the inner base wheel effectively disperse stress compared to right-angle turns, reducing stress concentration and preventing cracking under high pressure. This rapidly dissipates the large amount of heat generated during grinding, preventing the grinding wheel from annealing and softening due to overheating, thus preventing loss of wear resistance. Uniform cooling avoids uneven heating and cooling on the grinding wheel surface, preventing thermal stress concentration that could lead to deformation or cracking. This ensures the wear resistance of the grinding wheel, extends its lifespan, reduces the need for repeated screening and grinding at the end of the process, and ultimately lowers the energy consumption required for grinding slag powder.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To address the problem that existing grinding devices often suffer from irregular pitting on the smooth surface of the grinding wheel during actual use, leading to reduced grinding efficiency and poor wear resistance, please refer to [the relevant documentation / reference]. Figure 1 - Figure 4 This embodiment provides the following technical solution:

[0025] The double-layer combined slag powder grinding wheel of this embodiment includes an outer wear-resistant liner 1 and an inner base wheel 2. The inner base wheel 2 is inserted into the outer wear-resistant liner 1 and engages with it. The outer surface of the outer wear-resistant liner 1 is provided with an integrally formed concave annular groove 101. The interior of the concave annular groove 101 is provided with cross-patterns 102. The outer surface of the outer wear-resistant liner 1 adopts the design of concave annular groove 101 and cross-patterns 102. After grinding, the slag powder accumulates inside the concave annular groove 101.

[0026] The cross-pattern 102 surrounds the surface of the outer wear-resistant liner 1 and is integrally formed with the outer wear-resistant liner 1. The grinding contact area with the slag powder is still relatively large. However, due to the pre-set cross-pattern 102, the surface of the outer wear-resistant liner 1 has relatively few pits that are easily damaged by the slag powder. After grinding, the slag powder itself is automatically filled in, so the wear resistance of the surface of the outer wear-resistant liner 1 is better. At the same time, the grinding efficiency is maintained at a high level, which helps to extend the service life of the grinding wheel, reduce the repeated screening and grinding at the end of the process, and thus reduce the energy consumption required for grinding slag powder.

[0027] Specifically, the outer surface of the outer wear-resistant liner 1 adopts a design with a concave annular groove 101 and a cross pattern 102. After grinding, the slag powder accumulates inside the concave annular groove 101, forming a smooth surface with the cross pattern 102. The grinding contact area with the slag powder is still relatively large. However, due to the pre-set cross pattern 102, the surface of the outer wear-resistant liner 1 has relatively few pits that are easily damaged by the slag powder. After grinding, the slag powder itself is automatically filled in. Therefore, the wear resistance of the surface of the outer wear-resistant liner 1 is better, while the grinding efficiency is maintained at a high level, the power consumption is reduced, and the service life of the grinding wheel is extended.

[0028] To address the issues of existing grinding devices' simplistic structure, poor heat dissipation, and consequently, their long-term operational limitations, please refer to [the relevant documentation / reference]. Figure 1 - Figure 4 This embodiment provides the following technical solution:

[0029] In this embodiment, the outer surface of the inner base wheel 2 is provided with an integrally formed cooling channel 208. The cooling channel 208 is sealed to the inner wall of the outer wear-resistant liner 1. The inner surface of the outer wear-resistant liner 1 is provided with an integrally formed inner combination groove 103. The inner base wheel 2 is embedded in the inner combination groove 103 and fitted with the outer wear-resistant liner 1. The combination of the outer wear-resistant liner 1 and the inner base wheel 2 can realize the combined installation method, and the outer wear-resistant liner 1 and the inner base wheel 2 can be inspected and repaired separately.

[0030] In addition, a flange 201 is welded to the outside of the inner base wheel 2. Locking bolts 202 surround the flange 201, which fix the flange 201 and the outer wear-resistant liner 1. A heat sink 203 is provided on the outside of the flange 201. A cooling channel 208 extends into the heat sink 203 and communicates with it. Coolant is provided inside the cooling channel 208. A spiral cooling channel 208 is provided on the surface of the inner base wheel 2. The spiral shape is a structure that can effectively disperse stress. Compared with a right-angle turn channel, it can reduce stress concentration, prevent cracking from the channel under high pressure, and quickly remove the large amount of heat generated during the grinding process. This prevents the grinding wheel from annealing and softening due to overheating and losing its wear resistance. Uniform cooling avoids uneven heating and cooling on the surface of the grinding wheel, which can lead to thermal stress concentration and thus deformation or cracking.

[0031] In fact, a drive shaft 204 runs through the center of the inner base wheel 2, and an integrally formed keyway 205 is provided on the surface of the drive shaft 204. The drive shaft 204 is connected to the motor shaft of the grinding motor through the keyway 205.

[0032] Furthermore, a positioning block 206 is welded to the outer surface of the inner base wheel 2, and an integrally formed positioning slot 104 is provided on the inner wall of the inner combination groove 103. The positioning block 206 is inserted into the positioning slot 104 and engages with the outer wear-resistant liner 1. The inner base wheel 2 and the positioning block 206 are installed through the inner limit block 105 and the positioning slot 104 to maintain a stable position.

[0033] It should be noted that an integrally formed positioning port 207 is provided in the middle of the inner base wheel 2. The positioning port 207 is inserted into the outer wear-resistant liner 1 and slidably connected with the outer wear-resistant liner 1. An inner limiting block 105 is provided inside the outer wear-resistant liner 1. The inner limiting block 105 is embedded in the positioning insert 206 and slidably connected with the positioning insert 206.

[0034] Specifically, the combination of the outer wear-resistant liner 1 and the inner base wheel 2 allows for modular installation. Maintenance work can be performed on the outer wear-resistant liner 1 and the inner base wheel 2 separately. The inner base wheel 2 and the positioning insert 206 are installed via the inner limit block 105 and positioning slot 104 to maintain stable position. Simultaneously, the spiral cooling channel 208 on the surface of the inner base wheel 2 effectively disperses stress compared to a right-angle turn, reducing stress concentration and preventing cracking under high pressure. It also rapidly removes the large amount of heat generated during grinding, preventing the grinding wheel from annealing and softening due to overheating, thus preventing loss of wear resistance. Uniform cooling prevents uneven heating on the grinding wheel surface, avoiding thermal stress concentration that could lead to deformation or cracking.

[0035] Working Principle: During use, the outer wear-resistant liner 1 and the inner base wheel 2 are combined for assembly. Maintenance work can be performed on the outer wear-resistant liner 1 and the inner base wheel 2 separately. The inner base wheel 2 and the positioning insert 206 are installed via the inner limit block 105 and positioning slot 104 to maintain stable position. Simultaneously, the spiral cooling channel 208 on the surface of the inner base wheel 2 effectively disperses stress, reducing stress concentration compared to right-angle turns, preventing cracking under high pressure, and rapidly dissipating the large amount of heat generated during grinding. This prevents the grinding wheel from annealing and softening due to overheating, thus maintaining its wear resistance. Uniform cooling prevents grinding wheel wear. Uneven heating and cooling on the surface of the grinding wheel leads to thermal stress concentration, which in turn causes deformation or cracking. During operation, the outer surface of the outer wear-resistant liner 1 adopts a design with an inner concave annular groove 101 and cross-pattern 102. After grinding, the slag powder accumulates inside the inner concave annular groove 101, forming a smooth surface with the cross-pattern 102. The grinding contact area with the slag powder is still relatively large. However, due to the pre-set cross-pattern 102, the surface of the outer wear-resistant liner 1 has relatively few pits that are easily damaged by the slag powder. After grinding, the slag powder itself is automatically filled in, so the wear resistance of the outer wear-resistant liner 1 is better, and the grinding efficiency is maintained at a high level, which helps to extend the service life of the grinding wheel.
