Description
Technical Field
[0001] The present application relates to the technical field of sintering trolleys, and in particular to an anti-blocking grate for a sintering trolley. Background Art
[0002] In the iron and steel metallurgical industry, sintering trolleys are core equipment for sintering production. The performance of grates, a crucial component of sintering trolleys, directly impacts the efficiency and quality of sintering production. Currently, grates are typically secured to the trolley sidewalls by welding or bolts. While this method ensures grate stability during trolley operation, it presents numerous issues in actual use.
[0003] During the sintering process, some materials will inevitably accumulate in the gaps between adjacent grate bars. As the sintering process continues, these accumulated materials will be repeatedly heated at high temperatures, undergoing physical and chemical changes, gradually sintering into blocks and tightly bonding with the grate bars. Over time, adjacent grate bars will become locked due to the sintering of the materials. Once the grate bars are locked, not only will it be difficult to replace and maintain them normally, but the grate bars will also be unable to be updated in a timely manner, affecting the air permeability of the sintering trolley, reducing sintering efficiency, increasing energy consumption, and even potentially causing equipment failures due to local blockages, resulting in production interruptions and economic losses. Therefore, there is an urgent need to design a grate bar that can effectively reduce the occurrence of material blockages. Summary of the Invention

DETAILED DESCRIPTION
[0024] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.
[0025] The embodiment of the present application is: a sintering trolley anti-blocking grate, referring to Figure 1 and Figure 2 The sintering system comprises a plurality of grate bodies 1 arranged on a sintering carriage. In this embodiment, two grate bodies 1 are provided. Slots 11 are formed at both ends of the grate bodies 1. During installation, the slots 11 engage with the side beams of the carriage (not shown). During installation, a gap exists between the slots 11 and the carriage side beams.
[0026] Bosses 2 are provided on both sides of the middle section of the grate body 1. The bosses 2 are integrally formed with the grate body 1, and a gap exists between two adjacent grate bodies 1. Each grate body 1 has a receiving groove 12 on its sidewall, into which a blocking block 3 is slidably connected. The blocking block 3 is arranged along the length of the grate body 1. The sidewall of the blocking block 3 is placed in the gap between the two adjacent grate bodies 1. The receiving groove 12 is provided with an adjustment component 4 for adjusting the position of the blocking block 3.
[0027] Reference Figure 1 、 Figure 2 and Figure 3The adjustment assembly 4 includes a plurality of slide bars 41 arranged along the height direction of the receiving slot 12. The plurality of slide bars 41 are equidistantly arranged along the length direction of the receiving slot 12 and are fixedly connected within the receiving slot 12. A common abutment block 42 is provided and slidably connected to the plurality of slide bars 41. The lower end of the abutment block 42 faces a blocking block 3 provided with an inclined surface block 43. The inclined surface block 43 is fixedly connected within the bottom block, and the abutment block 42 abuts against the inclined surface of the inclined surface block 43. Under the abutment of the abutment block 42, part of the side wall of the blocking block 3 is placed in the gap between two adjacent grate bar bodies 1.
[0028] A right-angle plate 9 is provided at the upper portion of the receiving groove 12 and is arranged along the length of the receiving groove 12. One end of the right-angle plate 9 is fixedly connected to the blocking block 3. The right-angle plate 9 is provided with a plurality of sliding holes 91, which correspond one-to-one to the sliding rods 41 and are passed through the sliding holes 91.
[0029] Therefore, when the grate body 1 is upright, the abutment block 42 will press down the inclined block 43 under the action of gravity, so that the inclined block 43 drives the blocking block 3 to slide to the side away from the receiving groove 12, and finally places part of the side wall of the blocking block 3 outside the receiving groove 12. When the sintering trolley rotates to a certain angle and the grate body 1 is inverted, the abutment block 42 abuts against the right-angle plate 9. The abutment block 42 slides along the slide rod 41 toward the side of the right-angle plate 9 and abuts at the right angle, so that the right-angle plate 9 moves toward the inside of the receiving groove 12, thereby driving the blocking block 3 to move toward the inside of the receiving groove 12, so that the blocking block 3 shrinks to the inside of the receiving groove 12, and finally the blocking block 3 is completely placed in the receiving groove 12. This increases the gap between the two adjacent grate bodies 1, and at the same time, the upper edge of the blocking block 3 is cleaned and scraped through the upper edge of the receiving groove 12. At the same time, in order to facilitate the movement of the blocking block 3 , the side of the abutment block 42 close to the right-angle plate 9 is set to a pointed end, and the pointed end of the abutment block 42 points to the side of the right-angle plate 9 away from the blocking block 3 .
[0030] In order to make the movement of the blocking block 3 easier, a support rod 5 is fixedly connected to the inner wall of the receiving groove 12. In this embodiment, four support rods 5 are provided. A through hole 31 is provided on the blocking block 3 opposite to the support rod 5. The support rod 5 passes through the abutment block 42 and is inserted into the through hole 31. The length direction of the support rod 5 and the opening direction of the through hole 31 are parallel to the sliding direction of the blocking block 3 in the receiving groove 12. A plurality of pulleys 6 are rotatably connected in the through hole 31, and the plurality of pulleys 6 are equidistantly arranged along the length direction of the through hole 31. The through hole 31 abuts against the support rod 5. In this way, the blocking block 3 is slidably connected in the receiving groove 12 through the pulley 6 in the through hole 31 and the support rod 5, and the pulley 6 reduces the resistance encountered during its sliding process.
[0031] The upper edge of the blocking block 3 on the side away from the receiving groove 12 protrudes toward the side away from the receiving groove 12 at an acute angle. The protruding portion of the blocking block 3 is provided with an acute-angled protective plate 7. A fixing member 8 for fixing the acute-angled protective plate 7 to the blocking block 3 is provided between the acute-angled protective plate 7 and the blocking block 3. In this embodiment, the fixing member 8 is configured as a countersunk bolt. Two countersunk bolts are provided and are located at each end of the acute-angled protective plate 7. The countersunk bolts are threadedly connected to the acute-angled protective plate 7, and the shanks of the countersunk bolts are threadedly connected to the blocking block 3.
[0032] Then, the countersunk bolt is rotated so that the rod of the countersunk bolt is separated from the blocking block 3 , thereby quickly realizing the removal of the acute-angle protection plate 7 from the blocking block 3 .
