Description

Technical Field

[0001] This utility model relates to the field of dolomite crushing and processing technology, specifically to a dolomite powder stabilization crushing and processing device. Background Technology

[0002] In the sintering process of steel smelting, the particle size requirement for raw material dolomite is less than 3mm. However, among the sintered dolomite raw materials currently available on the market, materials with a particle size greater than 3mm still account for a certain proportion. This part of the material cannot be sintered and used because the particle size does not meet the sintering requirements, resulting in waste.

[0003] Current technologies commonly use double-roll crushers or hammer crushers to crush dolomite. However, due to the significant differences in the particle size of dolomite raw materials, crushing large-diameter dolomite raw materials directly with double-roll crushers or hammer crushers presents problems such as high crushing difficulty, long crushing time, and the need for repeated crushing, which affects work efficiency. At the same time, dolomite raw materials that meet the particle size requirements will also be crushed into smaller particles, which not only increases the workload of the crusher but also easily leads to the problem of excessively fine dolomite raw materials, affecting the stability of operation. Further improvements can be made. Utility Model Content

[0017] (1) This utility model is equipped with a primary crushing chamber, and a perforated plate is installed inside the primary crushing chamber. When crushing dolomite powder, the dolomite raw material can be put into the primary crushing chamber from the feed port. The dolomite raw material slides onto the top surface of the perforated plate. The drive motor drives the cam to rotate.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0027] According to an embodiment of the present invention, a dolomite powder stabilization crushing and processing device is provided.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a dolomite powder stabilization and crushing device according to an embodiment of the present invention includes a primary crushing chamber 1 and a double-roll crusher 7.

A return spring 13 is sleeved on the outside of the second guide rod 11. Support legs 9 are installed on the bottom fixed rod of the primary crushing chamber 1. A strong spring 5 is sleeved on the outer side of the first guide rod 4. Multiple sets of striking blocks 12 are arranged. An orifice plate 2 is installed inside the primary crushing chamber 1. When crushing dolomite powder, the dolomite raw material can be fed into the primary crushing chamber 1 through the feed inlet 18. The dolomite raw material slides onto the top surface of the orifice plate 2. The drive motor 15 drives the cam 16 to rotate. The rotation of the cam 16 pushes the lifting platform 14 to move up and down, which in turn drives the striking blocks 12 to move up and down to hammer the dolomite raw material for preliminary crushing. The dolomite raw material after preliminary crushing enters through the feed channel 6. The material is then subjected to secondary crushing in the double roll crusher 7, which avoids the problem of large pieces of dolomite affecting the crushing efficiency and particle size uniformity of the double roll crusher 7, thus improving crushing efficiency and stability. At the same time, during the process of the impact block 12 moving down to hammer the dolomite, the perforated plate 2 is subjected to hammering vibration. The vibration of the perforated plate 2 screens the dolomite raw material, and the dolomite powder particles that meet the particle size requirements are directly screened out by the screen holes 3 and discharged from the discharge port 8, avoiding the trouble of secondary crushing in the later stage, reducing the working intensity of the roll crusher, and further improving the working efficiency and working stability.

[0029] In one embodiment, a feed inlet 18 is provided through the other end of the top surface of the primary crushing chamber 1, and the feed inlet 18 is located above one end of the perforated plate 2, which facilitates the feeding of materials by the staff.

[0030] In one embodiment, the other end of the perforated plate 2 extends above the feed channel 6, and the perforated plate 2 is arranged at an angle to facilitate the downward sliding of the dolomite raw material.

[0031] In one embodiment, the sieve aperture 3 has a diameter of 3 mm and the sieve aperture 3 is densely distributed at equal intervals, which meets the screening requirements of dolomite raw materials.

[0032] In one embodiment, the elastic coefficient of the return spring 13 is less than that of the elastic coefficient of the strong spring 5, and the two ends of the return spring 13 are fixedly connected to the bottom surface of the lifting platform 14 and the top surface of the primary crushing chamber 1, respectively, so as to facilitate the reset of the lifting platform 14 and the striking block 12.

[0033] In one embodiment, multiple strong springs 5 ​​and first guide rods 4 are arranged, and the two ends of the strong springs 5 ​​are fixedly connected to the bottom surface of the orifice plate 2 and the bottom surface of the primary crushing chamber 1, respectively, so as to support the orifice plate 2 and connect the orifice plate 2.

[0034] In one embodiment, the bottom surface of the striking block 12 is parallel to the perforated plate 2, and the bottom surface of the striking block 12 is provided with protrusions 17 to increase the hammering and breaking effect.

[0035] In one embodiment, the surface of the cam 16 is polished and the top surface of the lifting platform 14 is polished to reduce frictional loss.

[0036] Working Principle: When crushing dolomite powder, the dolomite raw material can be fed into the primary crushing chamber 1 through the feed inlet 18. The dolomite raw material slides onto the top surface of the perforated plate 2. The drive motor 15 drives the cam 16 to rotate. The rotation of the cam 16 pushes the lifting platform 14 to move up and down, which in turn drives the impact block 12 to move up and down to hammer the dolomite raw material for preliminary crushing. After preliminary crushing, the dolomite raw material enters the double roll crusher 7 through the feed channel 6 for secondary crushing. This avoids the problem of large pieces of dolomite affecting the crushing efficiency and particle size uniformity of the double roll crusher 7, thus improving crushing efficiency and stability. At the same time, during the process of the impact block 12 moving down to hammer the dolomite, the perforated plate 2 is subjected to hammering vibration. The vibration of the perforated plate 2 screens the dolomite raw material. Dolomite powder particles that meet the particle size requirements are directly screened out by the screen holes 3 and discharged from the discharge port 8, avoiding the trouble of secondary crushing in the later stage, reducing the workload of the roller crusher, and further improving the working efficiency and stability.
