Description

Technical Field

[0001] The utility model relates to the technical field of steel production, in particular to a flexible sintering machine system with side sealing. Background Art

[0002] Sintering is a critical process in steel production, providing high-quality raw materials for blast furnace ironmaking. In existing sintering systems, the sintering trolley is located above the sintering bellows. After being filled with a mixture, the trolley runs on trolley tracks on both sides of the bellows. The ignition furnace ignites the top of the mixture, and the bellows draw air from the bottom of the sintering trolley, causing the mixture to sinter downward from the top of the sintering trolley. To ensure effective bellows ventilation, a reliable seal must be ensured between the sintering bellows and the sintering trolley, minimizing or eliminating air leakage.

[0003] Traditional rigid slideway seals rely primarily on the formation of an oil film with lubricating oil to achieve sealing. This requires extremely stringent conditions for the slideway and sliding plate to form a horizontal fit. Even the slightest loss of horizontality can cause the sliding plate spring to fail, preventing the lubricant from entering the slideway. This results in wasted lubricant, and air leakage in multiple locations can affect the quality of sintered ore, increase energy and power consumption, and increase costs, leading to reduced economic benefits. Therefore, a flexible, wear-resistant sealing structure was proposed (see Reference 1 for details).

[0004] Reference 1: Chinese patent document with patent publication number CN114739168B.

[0005] Reference 1 discloses a flexible slideway sealing device for a sintering machine and a sintering machine. The device comprises a flexible lower slideway with an open cross-section in a ring shape. The sealing portion of the flexible lower slideway is made of a flexible material and has a smoothly transitioning curve with a downwardly inclined end. When the trolley is in operation, the bottom surface of the upper slideway presses downward on the highest portion of the seal of the flexible lower slideway. This curved surface first contacts the lower surface of the upper slideway to form a seal. If the sealing surface of the trolley upper slideway and the sealing portion of the flexible lower slideway are not tightly sealed, the lateral pressure generated by the leaking airflow decreases, sucking up the remaining curved surface of the seal, thereby blocking the leaking area. The sealing between the sealing part and the upper slide is selectively achieved by reducing the lateral pressure generated by the leakage airflow. After the highest area of ​​the arc surface of the sealing part contacts and seals with the upper slide, if there is an air leakage area, the arc surface of the sealing part below the air leakage area will be pressed upward against the corresponding area of ​​the upper slide; if there is no air leakage area, the other arc surfaces of the sealing part remain detached from the upper slide. This can greatly reduce unnecessary contact between the arc surface of the sealing part of the flexible lower slide and the upper slide, while ensuring that the sealing part of the flexible lower slide can provide good sealing, and greatly reduce the friction between the upper slide and the flexible lower slide.

[0006] However, when there is an air leakage part as recorded in Reference 1, the sealing part of the flexible lower slide will stick to the upper slide under the top pressure of the side pressure. During this process, the upper slide continues to move with the sintering machine trolley, and the flexible lower slide is continuously fixed on the support frame. Therefore, the upper slide and the flexible lower slide will have relative displacement, resulting in mutual friction between the upper slide and the flexible lower slide, thereby increasing the speed of wear and failure of the flexible lower slide. Utility Model Content

[0007] The purpose of the utility model is to solve the problem in the prior art that the sliding friction between the flexible lower slide and the upper slide causes the wear speed of the flexible lower slide to increase, and to provide a flexible sintering machine system with side seals.

[0014] As a further optimization of the flexible sintering machine system with side sealing of the utility model: the side surface of the upper slideway facing the flexible lower slideway is set as a smooth surface.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The utility model provides a carrying belt tightened by two guide wheels as a support, thereby positioning the relative position of the flexible lower slide, and when the flexible lower slide is connected and sealed with the upper slide, the friction between the flexible lower slide and the upper slide can be used to enable the flexible lower slide to move with the upper slide, so as to reduce the mutual wear caused by the reverse sliding of the flexible upper slide and the upper slide under the friction.

Moreover, the flexible glide path is divided into multiple sections by multiple docking components, which makes it easy for the staff to replace different positions of the flexible glide path according to the different wear conditions of different positions of the flexible glide path.

[0026] In order to better understand the present invention, the content of the present invention is further explained below in conjunction with embodiments, but the content of the present invention is not limited to the following embodiments.

[0027] like Figure 1 and Figure 3 As shown, a flexible sintering machine system with side seals, similar to the prior art, includes a support frame 1 and a sintering machine trolley 7 that circulates on the support frame 1. The sintering machine trolley 7 circulates to perform the sintering process in steel. A bellows 8 is correspondingly provided below the sintering machine trolley 7, and the bellows 8 is provided on the support frame 1 to assist in completing the sintering process of steel. An upper slide 6 is provided on the sintering machine trolley 7. Preferably, the lower side of the upper slide 6 is a smooth surface. A flexible lower slide 3 corresponding to the upper slide 6 is provided on the support frame 1. Specifically, the flexible lower slide 3 is made of elastic rubber, such as Figure 5 As shown, the stable sealing of the side of the sintering machine trolley 7 is achieved to ensure the suction force of the bellows 8 to make the mixed material sintered downward from the top of the sintering machine trolley 7.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, unlike the prior art, the flexible lower slide 3 is fixed in an annular shape on the annular carrying belt 5, and the annular carrying belt 5 is connected to the two guide wheels 4 to form a belt transmission structure. The two guide wheels 4 are respectively arranged at the two inflection points of the circular rotation of multiple sintering machine trolleys 7, and the two guide wheels 4 are fixed on the support frame 1. The friction between the flexible lower slide 3 and the upper slide 6 can drive the flexible lower slide 3 to drive the carrying belt 5, which circulates through the guide wheels 4 under the support of the two guide wheels 4, thereby reducing the relative sliding of the flexible lower slide 3 and the upper slide 6 in the friction state, that is, reducing the wear between the flexible lower slide 3 and the upper slide 6, and improving the service life of the flexible lower slide 3.

[0029] The carrier belt 5 is a V-belt arrangement to maintain the rotational stability of the carrier belt 5 , and is made of high-temperature resistant rubber material to keep the carrier belt 5 taut during the sintering operation of the sintering machine trolley 7 .

[0030] The flexible downhill slide 3 is L-shaped, the shorter end of the flexible downhill slide 3 is vertically arranged, and a through hole is provided on it, which corresponds to the screw hole opened on the side of the carrying belt 5, and a stud is provided in the through hole to be threadedly connected to the screw hole to achieve a detachable connection between the flexible downhill slide 3 and the side of the carrying belt 5. The longer end of the flexible downhill slide 3 is inclined toward the upper slide 6, such as Figure 5 As shown, the flexible lower slide 3 is kept under pressure and fits the upper slide 6 to achieve a sealing effect.

[0031] The flexible downhill slide 3 maintains its relative position under the support of the carrier belt 5. At the same time, the carrier belt 5 and the two guide wheels 4 cooperate to make the flexible downhill slide 3 rotate cyclically. On the basis of maintaining the sealing effect on the side of the sintering machine trolley 7, the service life of the flexible downhill slide 3 is increased, that is, the replacement and installation cycle of the flexible downhill slide 3 is extended, thereby reducing the workload of the staff to a certain extent. When the cyclically rotating flexible downhill slide 3 is in a separated state from the upper slide 6, the flexible downhill slide 3 can be easily observed by the staff to determine the wear condition of the flexible downhill slide 3 at different positions.

[0032] The flexible downhill slide 3 is provided with multiple docking components 2, which divide the flexible downhill slide 3 into multiple segments and connect the multiple flexible downhill slides 3 end to end. When the damaged flexible downhill slide 3 needs to be replaced, the studs that fix the flexible downhill slide 3 to the carrier belt 5 can be unscrewed, and then the docking components 2 can be separated. Next, the corresponding position of the flexible downhill slide 3 can be removed, and the replacement can be completed after reversing the above operation. Therefore, there is no need to move the upper slide 6 to replace the flexible downhill slide 3, so that the staff can easily replace the flexible downhill slide 3 to achieve equipment maintenance.

[0033] like Figure 4 As shown, the docking component 2 includes a docking groove 201 and a docking protrusion 202. The docking groove 201 and the docking protrusion 202 are respectively arranged at the opposite ends of two adjacent flexible down slides 3. The docking groove 201 and the docking protrusion 202 are both Y-shaped. When the docking groove 201 and the docking protrusion 202 are docked, the connection stability and sealing of the flexible down slide 3 can be maintained, thereby ensuring the sealing effect and sealing stability of the flexible down slide 3 and the upper slide 6. At the same time, it can have a certain tensile force to prevent the flexible down slide 3 from moving with the upper slide 6. When the flexible down slide 3 is set at the docking component 2, the probability of wrinkles appearing, that is, the sealing effect of the flexible down slide 3 cooperating with the upper slide 6 is maintained.

[0034] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
