Description

Technical Field

[0001] The present invention relates to the technical field of ring coolers, in particular to a ring cooler for steel manufacturing. Background Art

[0002] Annular cooler is the abbreviation of ring cooler, which is used to effectively cool the sintered hot ore unloaded from the sintering machine. Annular cooler is the most widely used sintering cooling equipment in the steel manufacturing industry at home and abroad. Compared with the belt cooler, the annular cooler has the advantages of less space occupation, lower investment and higher equipment utilization rate.

[0003] Most of the ring coolers in the prior art are composed of a bellows, a trolley, a discharge chute and other parts. The trolley makes a circular motion inside the ring cooler to realize continuous transportation of the sintered ore to be cooled. However, since the trolley makes a circular motion and has a large turning radius, its motion law is more complicated than the linear motion of the trolley with a cooler. During operation, the trolley is very likely to run off the track, causing the trolley wheel rim to bite the edge of the rail, affecting the normal operation of the ring cooler and the cooling effect of the sintered ore. In addition, some ring coolers in the prior art also adopt a step-by-step unloading method when unloading. Frequent starting and stopping not only greatly reduces the efficiency of processing cooling, but also brings great pressure to the driving equipment. In response to the problems existing in the ring coolers used in the steel manufacturing industry in the above-mentioned prior art, we have proposed a ring cooler for steel manufacturing.

[0034] Example

[0035] See also Figure 1-7The annular cooler for steel manufacturing comprises a cooling carrier 1, on which an annular cooling seat 2 and a plurality of cooling air boxes 3 are fixedly mounted. An air-cooling cavity for cooling is opened on the annular cooling seat 2, and air outlet ends of the plurality of cooling air boxes 3 are interconnected with the air-cooling cavity. The bottom end of the annular cooling seat 2 is connected with a discharge pipe 4, and part of the discharge pipe 4 extends to the inside of the air-cooling cavity. Specifically, the cooling carrier 1 is convenient for carrying the entire device, and the discharge pipe 4 on the annular cooling seat 2 is convenient for discharging the cooled sintered hot ore. At the same time, a discharge space can be formed inside the air-cooling cavity through the side wall of the discharge pipe 4, thereby reducing the excessive discharge of cooling air inside the air-cooling cavity from the inside of the discharge pipe 4, and correspondingly increasing the cooling capacity of the annular cooler. It should be noted that the cooling air box 3 is an existing device well known to those skilled in the art, and its specific model and size can be customized during actual use, which will not be described in detail here.

[0036] The annular conveying plate 1 5 and the annular conveying plate 2 6 are located on the annular cooling seat 2, and the annular conveying plate 2 6 is located inside the annular conveying plate 1 5, so that a loading cavity is formed between the two, and the loading cavity is connected to the air-cooling cavity.

[0037] The annular top cover 9 is located on the annular conveying plate 1 5 and the annular conveying plate 2 6. The annular top cover 9 is fixedly mounted on the cooling carrier 1 through a plurality of support rods 10. The other ends of the annular conveying plate 1 5 and the annular conveying plate 2 6 are sealed and rotatably mounted on one end of the annular top cover 9. The annular top cover 9 is provided with a plurality of maintenance holes and feed holes. The plurality of maintenance holes are provided with cleaning and maintenance components 102, and the feed holes are provided with a feed component 103.

Through the cooperation of the feed component 103, it is convenient to allow the sintered hot ore unloaded from the sintering machine to enter the interior of the annular cooler.

[0038] The support platform 11 is located on the annular top cover 9, and the support platform 11 is fixedly mounted on two of the support rods 10. A driving mechanism 104 is installed on the support platform 11 for driving the annular conveying plate 2 6 to perform circular motion, and an exhaust dust removal mechanism 105 is provided between the support platform 11 and the annular top cover 9. Specifically, through the cooperation of the driving mechanism 104, it is convenient to drive the annular conveying plate 2 6 and the components fixed thereto to move, so as to realize continuous transportation of the sintered hot ore entering from the feeding assembly 103. Through the cooperation of the exhaust dust removal mechanism 105, it is convenient to preliminarily filter the dust inside the gas discharged from the loading cavity. When the gas contains other harmful substances, it can be treated by other air purification equipment. No more details are given on other equipment here.

[0039] Among them, the automatic unloading mechanism 101 includes a unloading guide plate 12 and multiple groups of unloading components. The unloading guide plate 12 is fixedly installed on multiple support rods 10 through multiple connecting blocks. The unloading guide plate 12 is composed of an annular straight plate and an annular arc plate. The annular arc plate corresponds to the unloading pipe 4. The annular straight plate and the annular arc plate are both provided with guide flow channels. The annular loading plate 8 is provided with multiple loading through holes. Multiple groups of unloading components are respectively installed inside the multiple loading through holes. Specifically, the unloading guide plate 12 is mainly suitable for controlling the state of the loading component, so that the loading component is in a loading state when it moves to the annular straight plate, and is in a unloading state when the loading component moves to the annular arc plate. At this time, the cooled sintered hot ore on the loading component will be discharged from the interior of the annular cooler through the lower unloading pipe 4, and the discharged cooled sintered hot ore through the hole is provided with a conveying device for continuous conveying.

[0040] The unloading assembly includes a unloading plate 13, a unloading rod 14, a unloading torsion spring 15, a unloading block 16 and a guide ball 17. Part of the unloading rod 14 is rotatably mounted on one side of the loading through hole, and one end of the unloading plate 13 is fixedly mounted on the unloading rod 14 of this part and is located inside the loading through hole. A plurality of cooling through holes for cooling the sintered hot ore are provided on the unloading plate 13. The other part of the unloading rod 14 extends to the outside of the annular conveying plate 5. The unloading block 16 is fixedly mounted on the unloading rod 14, one end of the unloading torsion spring 15 is fixedly mounted on the unloading block 16, and the other end is fixedly mounted on the outer wall of the annular conveying plate 5.

The unloading plate 13 is tightly fitted. At this time, the unloading plate 13 is in a horizontal position inside the loading through hole. When the driving mechanism 104 drives the unloading assembly to move, when the guide ball 17 moves to the annular arc plate, it is guided by the curvature of the annular arc plate and the torsional rebound of the unloading torsion spring 15, driving the unloading rod 14 to move. The unloading plate 13 is moved by the unloading rod 14, so that a certain angle is formed between the unloading plate 13 and the loading through hole. The sintered hot ore transported on the unloading plate 13 will slide down from the unloading plate 13 under the influence of gravity, and then be discharged from the inside of the unloading pipe 4, realizing the function of automatic unloading. After the unloading assembly passes through the annular arc plate, the guide flow channel will restrict the guide ball 17 to restore it to the loading state. It should be noted that in order to reduce the wear between the guide ball 17 and the guide flow channel, the guide ball 17 can be rotatably mounted on the unloading rod 14, which is mainly used to guide the change of the position of the unloading rod 14.

[0041] Among them, the cleaning and maintenance component 102 includes a cleaning and maintenance cover 18 and a cover handle 19.

The plurality of diverter plates 21 are fixedly mounted inside the feeding through-hole, wherein one end of the diverter plates 21 located on both sides of the feeding through-hole extends to the top of the annular loading plate 8 and contacts the annular loading plate 8. Specifically, after the sintering machine unloads the sintered hot ore, the sintered hot ore will pass through the feeding hopper 20 and fall onto the loading assembly on the annular loading plate 8 inside the loading cavity. Through the cooperation of the diverter plate 21, the sintered hot ore can be distributed more evenly on the loading assembly. At the same time, through the cooperation of the diverter plate 21 on one side, the sintered hot ore falling onto the annular loading plate 8 can be pushed to the loading assembly. Moreover, through the cooperation of the two diverter plates 21, the cooling air can be correspondingly reduced from overflowing the outside of the annular cooler through the feeding through-hole.

[0043] Among them, the driving mechanism 104 includes a driving motor 22, a reducer 23, a driving rod 24, a driving bracket 25, a large umbrella gear 26, and a small umbrella gear 27.

Specifically, when in use, the drive motor 22 is started, and the output end of the drive motor 22 drives the input end of the reducer 23 to rotate, so that the reducer 23 decelerates and increases the torque of the drive motor 22, and then drives the small umbrella gear 27 to rotate through the output end of the reducer 23, and drives the large umbrella gear 26 to rotate through the small umbrella gear 27, and drives the driving rotating rod 24 connected thereto to rotate through the large umbrella gear 26, and drives the driving bracket 25 to rotate through the driving rotating rod 24, and then drives the annular conveying plate 26 connected thereto to move through the driving bracket 25, and then drives the annular conveying plate 26 connected thereto to move, which can drive the annular loading plate 8 fixedly connected to the annular conveying plate 26 to move, thereby realizing continuous transportation of the sintered hot ore.
