Description

Technical Field

[0001] The invention relates to the technical field of sintering machines, in particular to a lower sealing slideway of a sintering machine. The invention also relates to a sealing device having the lower sealing slideway. Background Art

[0002] The sintering machine is the main equipment of the draft sintering production process. It consists of a series of sintering machine trolleys connected in series. Raw materials are injected into the sintering machine in sequence. The stable operation of the sintering machine trolley directly affects the stability of the sintering production process, and further affects the output and quality of sintered ore. During the operation of the sintering machine, the upper slide of the trolley runs on the lower slide of the wind box, and the upper slide of the trolley and the lower slide of the wind box are sealed by a sealing device.

[0003] The current sealing forms are as follows:

[0004] 1. The upper slide is an elastic and retractable metal slide, and the lower slide is a fixed metal slide or an elastic and retractable metal slide for sealing; 2. The upper slide is a fixed metal slide, and the lower slide is an elastic and retractable metal slide or a flexible non-metal slide for sealing; However, due to the complex working conditions of the sintering machine, the temperature at the ignition furnace at the head of the sintering machine and the wind box at the tail is relatively high. It is difficult for a general flexible non-metallic slide to adapt to the high temperature requirements, and the elastic metal seal is prone to produce a certain gap to adapt to the changes in installation accuracy and plane wear, causing air leakage in the system. Summary of the invention

[0005] In view of this, the present invention aims to provide a sealing slideway and a sealing device under a sintering machine, so as to improve the sealing effect and ensure the continuity and integrity of the sealing.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A sintering machine slideway sealing device comprises a support beam, a flexible slideway arranged along the length direction of the support beam, and hard slideways extending along both ends of the flexible slideway, wherein the lower sealing slideway further comprises a connecting portion arranged between the flexible slideway and the hard slideway;

[0008] The flexible slide has a mounting seat arranged on the support beam and a detachable flexible sealing belt arranged on the mounting seat, and the flexible sealing belt and the hard slide are respectively abutted and sealed with the upper sealing slide of the sintering machine; the top surface of the connecting portion gradually rises from one end close to the mounting seat to one end close to the hard slide, and the flexible sealing belt extends out of the mounting seat and is arranged on the connecting portion in a conformal manner.

[0009] Furthermore, a groove is provided at one end of the rigid slideway close to the connecting portion, and a fixing unit for fixing the end of the flexible sealing belt is provided in the groove.

[0010] Furthermore, the fixing unit has a pad block arranged in the groove and a pressure plate arranged on the pad block for pressing the flexible sealing belt, one end of the flexible sealing belt extending out of the mounting seat is arranged between the pad block and the pressure plate, and the top surface of the pressure plate is flush with the top surface of the hard slideway.

[0011] Furthermore, the pressing plate and the cushion block are arranged in a staggered manner, the opposite end surfaces of the pressing plate and the cushion block are arranged as corresponding inclined surfaces, the flexible sealing belt is arranged between the two inclined surfaces, and the top surface of the pressing plate is flush with the top surface of the flexible sealing belt.

[0012] Furthermore, the mounting seat includes a base plate arranged on the support beam, a fixed stop block arranged on the base plate, and a movable block arranged opposite to the fixed stop block and sliding back and forth on the base plate, and the side end of the flexible sealing belt in the length direction is arranged between the fixed stop block and the movable block.

[0013] Furthermore, a rotating handle is provided on the bottom plate at one side of the movable block, and a cam abutting against the movable block is provided on the rotating handle. Due to the rotation of the cam, the movable block slides toward the fixed stopper and clamps the flexible sealing belt.

[0014] Furthermore, the opposite end faces of the movable block and the fixed stopper are arranged as inclined surfaces corresponding to each other, the flexible sealing belt is arranged between the two inclined surfaces, and the flexible sealing belt is arranged at an acute angle to the support beam.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The lower sealing slide of the sintering machine described in the present invention can improve the sealing performance of the lower sealing slide by co-arranging a flexible slide and a hard slide. At the same time, by arranging the hard slides at both ends of the flexible slide, the influence of the high temperature of the sintering machine on the flexible slide can be avoided, thereby increasing the service life. By setting the connecting part, the continuity and integrity between the flexible slide and the hard slide can be improved, thereby further improving the sealing performance.

[0017] In addition, by fixing one end of the flexible sealing belt through the fixing unit, it is possible to ensure that the connection between the flexible sealing belt and the hard slideway is smoothly transitioned to form a complete whole, thereby ensuring the sealing effect. At the same time, by the inclined surface treatment of the pressure plate and the cushion block, a smooth sealing surface is formed between the flexible sealing belt, the hard slideway and the connection part, thereby ensuring that the upper sealing slideway is always in contact with the flexible sealing belt and the hard slideway.

[0018] In addition, the flexible sealing belt can be clamped on the mounting seat by the coordinated setting of the movable block and the fixed stopper, and the flexible sealing belt and the upper sealing slideway can be formed at a certain angle by the inclined surface treatment of the movable block and the fixed stopper, thereby increasing the contact area between the upper sealing slideway and the flexible sealing belt. The coordinated setting of the cam and the rotating handle can ensure that the movable block is kept in a clamped state.

[0019] Another object of the present invention is to provide a sealing device, which includes the lower sealing slide of the sintering machine as described above and an upper sealing slide arranged at the bottom of the trolley of the sintering machine and corresponding to the lower sealing slide; the upper sealing slide has a swimming plate groove arranged at the bottom of the trolley and an elastically retractable swimming plate arranged inside the swimming plate groove, and the swimming plate is respectively abutted and sealed against the flexible sealing belt and the hard slide.

[0020] Furthermore, an elastic member is provided between the swimming plate groove and the swimming plate.

[0021] Furthermore, the rigid slideway is made of a high-strength self-lubricating carbon fiber high-temperature resistant composite plate; and / or adjacent rigid slideways are inserted into each other.

At the same time, an elastic member is arranged to ensure that the swimming plate can float up and down to improve the sealing effect. The hard slide adopts a high-strength self-lubricating carbon fiber high-temperature resistant composite plate to ensure that no lubrication equipment is required to avoid polluting the environment.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Embodiment 1

[0045] This embodiment relates to a lower sealing slideway of a sintering machine, and the overall structure is as follows: Figures 1 to 5 As shown, the lower sealed slide includes a support beam 1, a flexible slide 2 arranged along the length direction of the support beam 1, a hard slide 3 extending along both ends of the flexible slide 2, and a connecting portion 4 provided between the flexible slide 2 and the hard slide 3.

[0046] The flexible slide 2 has a mounting seat 201 disposed on the support beam 1 and a detachable flexible sealing belt 202 disposed on the mounting seat 201. The flexible sealing belt 202 and the hard slide 3 are respectively abutted and sealed against the upper sealing slide 5 of the sintering machine. The top surface of the connecting portion 4 gradually rises from one end close to the mounting seat 201 to one end close to the hard slide 3. The part of the flexible sealing belt 202 extending out of the mounting seat 201 is arranged on the connecting portion 4 in a conformal manner.

[0047] It is worth mentioning that the top surface of the connecting part 4 gradually rises from one end to the other end along the length direction to form a ramp, which is connected to the flexible slide 2 at the lower part and to the hard slide 3 at the higher part. Then, one side of the flexible sealing belt 202 along the length direction is fixed to the connecting part 4, and the other side gradually changes with the shape of the connecting part 4. The end of the flexible sealing belt 202 extending out of the mounting seat 201 is fixed on the hard slide 3, thereby ensuring the continuity between the flexible slide 2 and the hard slide 3, making them smoothly transition and connect, and further ensuring that the upper sealing slide 5 always maintains abutment and sealing with the lower sealing slide to avoid air leakage.

[0048] In addition, the rigid slide 3 adopts a high-strength self-lubricating carbon fiber high-temperature resistant composite plate. The composite plate has a self-lubricating function and also has good high-temperature resistance and wear resistance. Of course, the rigid slide 3 can also adopt other self-lubricating and high-temperature resistant materials in the prior art, which will not be repeated here. The connection between the rigid slides 3 is connected by plug-in. Such a setting can solve the problem of air leakage at the joint. The flexible sealing belt 202 is composited with non-metallic polymer materials with wear-resistant and high-temperature resistant properties to ensure durability.

[0049] Based on the overall introduction above, the lower sealing slideway of the sintering machine of this embodiment is a preferred embodiment. In this embodiment, a groove 301 is provided at one end of the hard slideway 3 close to the connecting portion 4, and a fixing unit 302 for fixing the end of the flexible sealing belt 202 is provided in the groove 301. The fixing unit 302 can fix the flexible sealing belt 202, and the top surface of the fixing unit 302 is flush with the top surface of the hard slideway 3, which can ensure the integrity between the flexible slideway 2 and the hard slideway 3 to form a continuous whole.

[0050] It should be noted that if Figure 2 and Figure 5 As shown, the fixing unit 302 of this embodiment has a pad 3021 arranged in the groove 301 and a pressing plate 3022 arranged on the pad 3021 for pressing the flexible sealing belt 202, and one end of the flexible sealing belt 202 extending out of the mounting seat 201 is arranged between the pad 3021 and the pressing plate 3022, and the top surface of the pressing plate 3022 is flush with the top surface of the hard slide 3.

[0051] Specifically, the function of the cushion block 3021 is to ensure that the mounting seat 201 is parallel to the bottom surface of the groove 301, thereby avoiding misalignment, and the pressure plate 3022 clamps the flexible sealing belt 202 and ensures that it is flush with the top surface of the hard slide 3, thereby ensuring the smoothness of the upper sealing slide 5 when it runs to the connecting part 4.

[0052] As a preferred embodiment, Figure 5 As shown, in this embodiment, the pressing plate 3022 and the cushion block 3021 are arranged in a staggered manner, the corresponding end surfaces of the pressing plate 3022 and the cushion block 3021 are set as mutually corresponding inclined surfaces, the flexible sealing belt 202 is set between the two inclined surfaces, and the top surface of the pressing plate 3022 is flush with the top surface of the flexible sealing belt 202. The pressing plate 3022 and the cushion block 3021 of this embodiment are arranged in this way to avoid misalignment between the flexible sealing belt 202 and the pressing plate 3022, ensuring the continuity of the flexible sealing belt 202, the pressing plate 3022 and the hard slide 3. The inclined surface arrangement of the pressing plate 3022 and the cushion block 3021 can also prevent the flexible sealing belt 202 from bending when being pressed, causing breakage.

[0053] In order to facilitate the disassembly and assembly of the flexible sealing belt 202, as a preferred embodiment, Figure 3 and Figure 4 As shown, the mounting seat 201 of this embodiment includes a bottom plate 2015 disposed on the support beam 1, a fixed stopper 2011 disposed on the bottom plate 2015, and a movable block 2012 disposed opposite to the fixed stopper 2011 and reciprocatingly sliding on the bottom plate 2015, and the side end of the flexible sealing belt 202 in the length direction is disposed between the fixed stopper 2011 and the movable block 2012. Through the clamping of the movable block 2012 and the fixed stopper 2011, it can be ensured that the flexible sealing belt 202 can be fixed on the mounting seat 201.

[0054] Preferably, in this embodiment, a rotating handle 2013 is provided on the bottom plate 2015 at one side of the movable block 2012, and a cam 2014 is provided on the rotating handle 2013 to abut against the movable block 2012. The rotation of the cam 2014 causes the movable block 2012 to slide toward the fixed stopper 2011, thereby clamping the flexible sealing belt 202. Specifically, by rotating the rotating handle 2013, the cam 2014 rotates following the rotating handle 2013, and the protruding portion of the cam 2014 pushes the movable block 2012 to slide, thereby clamping the flexible sealing belt 202 between the movable block 2012 and the fixed stopper 2011, so as to facilitate the disassembly and assembly of the flexible sealing belt 202.

[0055] It should be noted that, in this embodiment, the opposite end faces of the movable block 2012 and the fixed stopper 2011 are set as mutually corresponding inclined surfaces, and the flexible sealing belt 202 is set between the two inclined surfaces, so that the flexible sealing belt 202 is set at an acute angle with the support beam 1. The inclined surfaces of the movable block 2012 and the fixed stopper 2011 can ensure that the flexible sealing belt 202 is set at an acute angle with the support beam 1, and such a setting can ensure the maximum contact area after the upper sealing slide 5 and the flexible slide 2 are abutted, thereby improving the sealing performance.

[0056] The lower sealing slide of the sintering machine described in this embodiment can improve the sealing of the lower sealing slide through the coordinated arrangement of the flexible slide 2 and the hard slide 3. At the same time, by arranging the hard slide 3 at both ends of the flexible slide 2, the influence of the high temperature of the sintering machine on the flexible slide 2 can be avoided, thereby increasing the service life. By setting the connecting part 4, the continuity and integrity between the flexible slide 2 and the hard slide 3 can be improved, thereby further improving the sealing. Embodiment 2

[0057] This embodiment relates to a sealing device, such as Figures 6 to 8 As shown, the sealing device includes the lower sealing slide as above and an upper sealing slide 5 arranged at the bottom of the trolley 6 of the sintering machine and corresponding to the lower sealing slide. The upper sealing slide 5 has a swimming plate groove 501 arranged at the bottom of the trolley 6 and an elastically retractable swimming plate 502 arranged inside the swimming plate groove 501. The swimming plate 502 is respectively abutted and sealed against the flexible sealing belt 202 and the hard slide 3.

[0058] It should be noted that if Figure 8 As shown, in this embodiment, an elastic member 503 is provided between the swimming plate groove 501 and the swimming plate 502. When the trolley 6 is running, the coordinated arrangement of the elastic member 503 and the swimming plate 502 can serve as an elastic compensation structure. The swimming plate 502 can float up and down, and the height of the sealing surface can be adjusted at any time during the movement, ensuring that a sealing effect can be achieved on both the flexible slide 2 and the hard slide 3.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
