A sintering machine trolley with a sealed structure

Abstract

This utility model discloses a sintering machine trolley with a sealed structure, including a sintering chamber frame, a sintering channel, and a material conveying mechanism. The material conveying mechanism includes two rotating shafts and several sintering machine trolley side panels. Adjacent sintering machine trolley side panels are hinged together. Both ends of the sintering chamber frame are slidably connected to sealing plates. Each of the several sintering machine trolley side panels has a U-shaped receiving groove on both sides. A U-shaped sealing strip is slidably connected to the inner wall of the U-shaped receiving groove. Adjacent U-shaped sealing strips press against each other. Through the U-shaped sealing strips of adjacent sintering machine trolley side panels, relying on the thrust of the compression springs in the U-shaped receiving grooves, they continuously extend outward. After pressing against each other, the U-shaped sealing strips fill the hinge gaps of the side panels, forming a sealing barrier. This can prevent the ore from leaking from the gaps, avoiding raw material waste. At the same time, it prevents leaked material from accumulating on the track and at the bottom of the trolley, eliminating the hidden danger of jamming the wheel assembly and ensuring the stability of the trolley's cyclic operation.

Description

Technical Field

[0001] This utility model relates to the field of sintering machine trolley technology, specifically a sintering machine trolley with a sealed structure. Background Technology

[0002] In the iron and steel metallurgical industry, the sintering machine is a key piece of equipment for processing raw materials such as iron ore powder, fuel, and flux into sinter. The sintering machine trolley, as its core component, is responsible for carrying the ore and completing the entire sintering process. It consists of a steel frame, grates, baffles, and wheel sets. Multiple trolleys are connected end-to-end to form a closed loop chain, moving cyclically along a track, constituting a material conveying and reaction platform. To accommodate the loop chain's cyclical operation, the baffles of adjacent trolleys are usually hinged to meet the angle adjustment requirements of track turns, ensuring operational flexibility and continuity. However, in practical applications, gaps formed at the baffle connection points can easily lead to ore leakage (especially fine particles), causing raw material waste. Accumulated leaked material increases cleaning difficulty and can even jam the wheel sets, affecting operation. Simultaneously, gaps can cause air leakage during sintering ventilation, disrupting the airflow distribution in the material layer, reducing sintering efficiency and increasing energy consumption. Furthermore, long-term material erosion and airflow wear exacerbate wear on the hinged parts, affecting the equipment's service life.

[0003] Therefore, this utility model provides a sintering machine trolley with a sealed structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sintering machine trolley with a sealed structure to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sintering machine trolley with a sealed structure, comprising a sintering chamber frame, a sintering channel, and a material conveying mechanism. The material conveying mechanism includes two rotating shafts and several sintering machine trolley side panels. Adjacent sintering machine trolley side panels are hinged together. Sealing plates are slidably connected to both ends of the sintering chamber frame. U-shaped receiving grooves are provided on both sides of several sintering machine trolley side panels. U-shaped sealing strips are slidably connected to the inner walls of the U-shaped receiving grooves. Adjacent U-shaped sealing strips are pressed against each other. Two compression springs are installed on the inner walls of the U-shaped receiving grooves. The compression springs contact the corresponding side of the U-shaped sealing strip to push the U-shaped sealing strip outward. The width of the sealing plate is adapted to the inner side of the sintering machine trolley side panel. A gap exists between the sealing plate and the bottom and top surfaces of the sintering machine trolley side panel for material passage.

[0006] Preferably, a heat-resistant plate is provided at the top of the sintering machine trolley side panel, and the sintering machine trolley side panel contacts the material through the heat-resistant plate.

[0007] Preferably, the U-shaped sealing strip has two guide rods installed on the side of the sintering machine trolley railing, the guide rods are slidably connected to the inner wall of the sintering machine trolley railing, and the compression spring is sleeved on the outer side of the guide rod.

[0008] Preferably, the sintering machine trolley railing has four limiting grooves, and one end of each of the four guide rods in the sintering machine trolley railing is equipped with a limiting ring, which is slidably connected to the inner wall of the corresponding limiting groove.

[0009] Preferably, a laser displacement sensor is installed on the side wall of one of the sealing plates to detect the height of the material to be entered into the sintering channel. Three support plates are installed at both ends of the sintering chamber frame. An electric telescopic rod is installed at the top of the sealing plate and is mounted on the corresponding support plate.

[0010] Preferably, a guide rod is installed at the top of each of the two sealing plates, and the guide rod passes through the top of the corresponding support plate.

[0011] Beneficial effects

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] (1) In this utility model, the U-shaped sealing strips of the adjacent sintering machine trolley side panels extend outward continuously by relying on the thrust of the compression spring in the U-shaped receiving groove. After mutual compression, the U-shaped sealing strips fill the hinge gaps of the side panels, forming a sealing barrier. This can prevent the ore from leaking out of the gaps and avoid waste of raw materials. At the same time, it prevents the leaked material from accumulating on the track and the bottom of the trolley, eliminates the hidden danger of jamming the wheel set, and ensures the stability of the trolley's cyclic operation.

[0014] (2) This utility model reduces the amount of air leakage from the hinge gap of the railing and the non-working area of ​​the sintering channel during sintering exhaust by the dual action of the U-shaped sealing strip and the compression sealing of the adjacent railing and the matching and blocking of the sealing plate to the opening of the sintering channel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A sintering machine trolley with a sealed structure includes a sintering chamber frame 1, a sintering channel 11, and a material conveying mechanism 2. The material conveying mechanism 2 includes two rotating shafts 21 and several sintering machine trolley side panels 22. Two adjacent sintering machine trolley side panels 22 are hinged together. Both ends of the sintering chamber frame 1 are slidably connected with sealing plates 3.

[0023] Among them, several sintering machine trolley side panels 22 are provided with U-shaped receiving grooves 221 on both sides. U-shaped sealing strips 23 are slidably connected to the inner wall of the U-shaped receiving groove 221. Two adjacent U-shaped sealing strips 23 are pressed and contacted with each other. Two compression springs 24 are installed on the inner wall of the U-shaped receiving groove 221. The compression springs 24 contact one side of the corresponding U-shaped sealing strip 23 to push the U-shaped sealing strip 23 outward.

[0024] It should be noted that the U-shaped sealing strip 23 described in this embodiment slides and extends in the corresponding U-shaped receiving groove 221, and the two compression springs 24 in the U-shaped receiving groove 221 are symmetrically distributed.

[0025] The width of the sealing plate 3 is adapted to the inner side of the sintering machine trolley side panel 22, and there is a gap between the sealing plate 3 and the bottom and top surfaces of the sintering machine trolley side panel 22 for material to pass through.

[0026] It should be noted that the sealing plate 3 described in this embodiment adjusts the passability of the sintering channel 11 opening in real time.

[0027] Specifically, in the material conveying mechanism 2, two rotating shafts 21 rotate, driving several sintering machine trolley side panels 22 connected by hinges to move cyclically along the track, realizing the carrying and conveying of raw materials such as iron ore powder, fuel, and flux. The sealing plates 3 at both ends of the sintering chamber frame 1 can slide along the frame, adjusting the degree of obstruction of the opening of the sintering channel 11 in real time according to the sintering operation requirements. During the operation of the sintering machine trolley side panels 22, the U-shaped sealing strips 23 in the U-shaped receiving grooves 221 on both sides are continuously pushed by the two symmetrically distributed compression springs 24 installed on the inner wall of the U-shaped receiving grooves 221. Extending outwards, when two adjacent sintering machine trolley side panels 22 approach and rotate relative to each other, the extended U-shaped sealing strips 23 press against each other, using the elastic deformation of the sealing strips to fill the gaps at the hinges of the sintering machine trolley side panels 22; the width of the sealing plate 3 is adapted to the inner side of the sintering machine trolley side panels 22, so that when the sintering machine trolley side panels 22 circulate through the opening of the sintering channel 11, it does not obstruct the passage of the sintering machine trolley side panels 22 and the carried materials, and with the cooperation of the side panels, it helps to strengthen the sealing of the sintering channel 11 during non-material feeding and sintering operation periods, and maintains the airflow environment required for exhaust sintering.

[0028] In one embodiment of this utility model, such as Figures 1-5 As shown, a heat-resistant plate 222 is provided at the top of the sintering machine trolley side panel 22, and the sintering machine trolley side panel 22 contacts the material through the heat-resistant plate 222.

[0029] Specifically, a heat-resistant plate 222 is provided at the top of the sintering machine trolley side panel 22. When the sintering machine trolley side panel 22 carries materials such as iron ore powder, fuel, and flux, the sintering machine trolley side panel 22 does not directly contact the materials, but rather contacts the materials through the heat-resistant plate 222 at its top. The heat-resistant properties of the heat-resistant plate 222 are used to isolate the high temperature generated by the materials during the sintering process from the direct effect on the sintering machine trolley side panel 22.

[0030] In one embodiment of this utility model, such as Figures 1-5 As shown, two guide rods 25 are installed on the side of the U-shaped sealing strip 23 near the corresponding sintering machine trolley side panel 22. The guide rods 25 are slidably connected to the inner wall of the corresponding sintering machine trolley side panel 22, and the compression spring 24 is sleeved on the outer side of the corresponding guide rod 25.

[0031] Specifically, when the U-shaped sealing strip 23 slides along the U-shaped receiving groove 221 under the thrust of the compression spring 24, the guide rod 25 slides synchronously with the U-shaped sealing strip 23, limiting the extension and retraction direction of the compression spring 24, preventing the spring from shifting laterally or twisting during the force process, ensuring that the compression spring 24 can stably apply thrust to the U-shaped sealing strip 23, so that the U-shaped sealing strips 23 of adjacent panels always maintain a reliable squeeze contact sealing state.

[0032] In one embodiment of this utility model, such as Figures 1-5As shown, four limiting grooves 223 are provided in the sintering machine trolley side panel 22. One end of each of the four guide rods 25 in the sintering machine trolley side panel 22 is equipped with a limiting ring 26, and the limiting ring 26 is slidably connected to the inner wall of the corresponding limiting groove 223.

[0033] It should be noted that the limiting groove 223 described in this embodiment restricts the range of motion of the guide rod 25 and the U-shaped sealing strip 23 through the limiting ring 26.

[0034] Specifically, when the U-shaped sealing strip 23 slides along the U-shaped receiving groove 221 under the thrust of the compression spring 24 or the squeezing action of the adjacent guardrail, the guide rod 25 drives the limiting ring 26 to slide synchronously within the limiting groove 223. The limiting groove 223 indirectly constrains the extension range of the guide rod 25 and the activity range of the U-shaped sealing strip 23 by limiting the sliding stroke of the limiting ring 26, preventing the guide rod 25 from coming out of the guardrail 22 of the sintering machine trolley, and at the same time preventing the U-shaped sealing strip 23 from leaving the normal working position due to excessive extension or contraction, thus ensuring the stability and reliability of the sealing structure.

[0035] In one embodiment of this utility model, such as Figures 1-5 As shown, a laser displacement sensor 31 is installed on the side wall of one of the sealing plates 3 to detect the height of the material to be entered into the sintering channel 11. Three support plates 12 are installed at both ends of the sintering chamber frame 1. An electric telescopic rod 32 is installed on the top of the sealing plate 3 and is installed on the corresponding support plate 12.

[0036] It should be noted that the electric telescopic rod 32 described in this embodiment controls the lifting and lowering of the sealing plate 3.

[0037] Specifically, when the laser displacement sensor 31 detects the height of the material to be entered into the sintering channel 11, it controls the extension and retraction of the electric telescopic rod 32 based on the detection data, thereby adjusting the lifting height of the sealing plate 3. This ensures that a gap is maintained between the sealing plate 3 and the sintering machine trolley side panel 22 to match the material height, thus ensuring that the material can pass smoothly through the sintering channel 11. Furthermore, the precise adjustment of the sealing plate 3 strengthens the sealing control of the opening of the sintering channel 11, reducing unnecessary air leakage.

[0038] In one embodiment of this utility model, such as Figures 1-5 As shown, guide rods 33 are installed at the top of both sealing plates 3, and the guide rods 33 pass through the top of the corresponding support plates 12.

[0039] It should be noted that the two guide rods 33 on the corresponding side described in this embodiment are symmetrically distributed.

[0040] Specifically, when the electric telescopic rod 32 drives the sealing plate 3 to lift and lower, the guide rod 33 slides synchronously along the through hole of the support plate 12 with the sealing plate 3. The symmetrically distributed guide rods 33 limit and guide the lifting and lowering trajectory of the sealing plate 3, preventing the sealing plate 3 from tilting or deviating during the lifting and lowering process. This ensures that the sealing plate 3 can accurately cooperate with the sintering machine trolley side panel 22, maintain a suitable gap between it and the side panel, ensure the smooth passage of materials, and stably perform the sealing function of the opening of the sintering channel 11.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] Working principle: The two rotating shafts 21 of the material conveying mechanism 2 drive several articulated sintering machine trolley side panels 22 to move in a cycle, realizing material carrying and conveying; the U-shaped sealing strips 23 in the U-shaped receiving grooves 221 on both sides of the sintering machine trolley side panels 22 extend outward under the thrust of the compression springs 24, and the adjacent sealing strips squeeze each other to fill the articulated gaps. The guide rod 25 guides the springs, and the limiting ring 26 cooperates with the limiting groove 223 to limit the range of motion of the sealing strips. The sealing plates 3 at both ends of the sintering chamber frame 1 are driven to rise and fall by the electric telescopic rods 32. The laser displacement sensor 31 detects the material height to adjust the height of the sealing plate 3. The guide rod 33 ensures its smooth rise and fall. The sealing plate 3 is adapted to the trolley side panels, leaving gaps for material to pass through and strengthening the sealing of the sintering channel 11. The heat-resistant plate 222 at the top of the trolley side panels isolates high temperature and ensures stable operation of the equipment.
