Description

Technical Field

[0001] The utility model relates to a sealing device for a cooler, in particular to a sealing device for a belt cooler, and belongs to the technical field of sintering. Background Art

[0002] Belt cooler is a commonly used sinter cooling equipment. The cooling effect of belt cooler is related to its sealing performance. Poor sealing performance will not only affect the cooling effect of sinter, but also increase energy consumption and deteriorate the on-site production environment. Figure 1 As shown in FIG. 1 , the junction between the belt cooler body and the sealing cover of the existing belt cooler is the main air leakage point. Figure 2 As shown, the blower blows cold air into the bottom of the cooling machine trolley through the air duct to cool the sintered ore on the trolley, and the cooled hot air is discharged through the chimney on the sealing cover above the cooling machine trolley (currently, the hot exhaust gas discharged from the chimney on the sealing cover is usually used for hot air sintering).

[0003] The sealing structure between the existing belt cooling machine trolley and the sealing cover is as follows: Figure 3 As shown in the figure, the belt cooler trolley guardrail and the bottom of the sealing cover are mainly sealed by a rubber sheet. However, the following problems exist when the belt cooler trolley guardrail and the bottom of the sealing cover are sealed by a rubber sheet: first, it is difficult for the rubber sheet to maintain close contact with the belt cooler trolley guardrail, so the sealing effect is poor and the air leakage is serious; in addition, the high-temperature exhaust gas in the belt cooler often burns the rubber sheet, especially near the tail unloading point of the sintering machine. The temperature of the sintered ore that is just unloaded onto the belt cooler is high, and the exhaust gas temperature can be as high as 400 degrees or more. During blast cooling, the high-temperature hot air carrying high-temperature particles can easily burn the rubber sheet. Utility Model Content

[0004] In view of the problems of poor sealing, serious air leakage, and poor cooling effect of sintered ore at the junction of the existing belt cooler trolley and the sealing cover, the utility model proposes a new type of belt cooler sealing device. Based on the existing rubber plate seal, the utility model adds an angle steel sealing mechanism, and a buffer zone is formed between the angle steel and the inner plate of the trolley guardrail, which effectively prevents most of the high-temperature particles in the trolley from being blown to the trolley guardrail. The existence of the buffer zone also effectively reduces the flow rate of hot exhaust gas at the trolley guardrail, thereby effectively reducing the damage of high-temperature dust-containing exhaust gas to the rubber plate. Moreover, the angle steel sealing mechanism is a rigid seal, which effectively blocks most of the heat and ensures that the soft seal of the rubber plate can play a better role.

[0005] The utility model also adds a primary sealing mechanism between the angle steel sealing mechanism and the rubber plate sealing. The utility model can effectively improve the sealing effect at the junction of the belt cooling machine trolley and the sealing cover by designing the primary sealing of the angle steel sealing mechanism, the secondary sealing of the primary sealing mechanism, and the tertiary sealing of the rubber plate, effectively reduce the air leakage rate, and improve the cooling effect of the sintered ore.

A sealing cover inner plate is arranged on the inner side of the sealing cover. The angle steel sealing mechanism comprises a connecting steel plate and an angle steel. The rubber sealing mechanism comprises a rubber plate. The inner side of the sealing cover inner plate is connected to the connecting steel plate.

The functional plate is arranged on the trolley guardrail. The rubber plate is arranged vertically, the upper end of the rubber plate is connected to the sealing cover inner plate, and the lower end of the rubber plate is connected to the functional plate.

[0008] In the utility model, the device also includes a primary sealing mechanism arranged between the angle steel sealing mechanism and the rubber sealing mechanism. The primary sealing mechanism includes a support and a hanging plate. The support is fixedly mounted on the lower inner part of the inner plate of the sealing cover. The upper end of the hanging plate is connected to the support, and the lower end of the hanging plate is connected to the functional plate.

[0009] In the utility model, a first sealing groove is provided on the function plate below the support, and the lower end of the hanging plate extends into the first sealing groove.

[0010] In the utility model, the primary sealing mechanism further comprises a rotating shaft. The hanging plate is movably connected to the support via the rotating shaft. In a vertical plane, the hanging plate swings along with the rotating shaft, and the lower end of the hanging plate is located in the first sealing groove.

[0011] In the utility model, a second sealing groove is provided on the function plate below the rubber plate. The upper end of the rubber plate is fixedly connected to the lower outer portion of the inner plate of the sealing cover, and the lower end of the rubber plate extends into the second sealing groove.

[0012] In the utility model, asbestos sealing layers are provided in both the first sealing groove and the second sealing groove, wherein the lower end of the hanging plate is in close contact with the asbestos sealing layer in the first sealing groove, and the lower end of the rubber plate is in close contact with the asbestos sealing layer in the second sealing groove.

[0013] In the utility model, the functional panel is tiltedly arranged on the trolley guardrail, and a triangular heat-insulating cavity is formed between the functional panel, the trolley guardrail and the trolley inner side plate.

[0014] Preferably, the top elevation of the functional panel is lower than the bottom elevation of the inner panel of the sealing cover.

[0015] In the utility model, the rubber sealing mechanism further comprises a screw and a fastening nut. The screw is fixedly mounted on the lower outer side of the inner plate of the sealing cover. The upper end of the rubber plate passes through the screw and is fixed to the inner plate of the sealing cover through the fastening nut.

[0016] Preferably, the rubber sealing mechanism further comprises an asbestos pad and a pressing steel plate, wherein the asbestos pad is arranged between the inner plate of the sealing cover and the rubber plate, and the pressing steel plate is arranged between the rubber plate and the fastening nut.

[0017] In the utility model, the buffer spacing of the buffer zone in the width direction of the trolley is 45-55 mm, preferably 48-52 mm.

[0018] Preferably, a first baffle is further provided at the outer edge of the first sealing groove on the functional plate. The asbestos sealing layer in the first sealing groove is extended to the inner side of the first baffle.

[0019] Preferably, a second baffle is further provided at the outer edge of the second sealing groove on the functional plate. The asbestos sealing layer in the second sealing groove is extended to the inner side of the second baffle.

[0020] In view of the problems of poor sealing, serious air leakage and poor cooling effect of sintered ore at the junction between the existing belt cooler trolley and the sealing cover, the utility model proposes a new sealing device for the belt cooler. The innovation of the utility model is to improve the sealing and reduce the air leakage rate by improving the structure of the junction between the trolley guardrail and the sealing cover of the belt cooler (i.e., belt cooler), thereby improving the cooling effect of the sintered ore. On the basis of the existing rubber plate seal, the utility model adds an angle steel sealing mechanism, and a buffer zone is formed between the angle steel and the inner side plate of the trolley guardrail, which effectively prevents most of the high-temperature particles in the trolley from being blown to the trolley guardrail. The existence of the buffer zone also effectively reduces the flow rate of hot exhaust gas at the trolley guardrail, thereby effectively reducing the damage of the high-temperature dust-containing exhaust gas to the rubber plate. Moreover, the angle steel sealing mechanism is a rigid seal, which effectively blocks most of the heat and ensures that the soft seal of the rubber plate can play a better role.

[0021] Specifically, Figure 4 As shown, the utility model welds a connecting steel plate and an angle steel on the inner side of the inner plate of the sealing cover, and the angle steel is located at the lower part of the connecting steel plate, so that the angle steel can be covered on the outer periphery of the inner plate of the trolley of the trolley guardrail to form a preliminary seal. The preliminary seal of the angle steel sealing mechanism has the following effects: because the belt cooler is blast cooling, it is inevitable that high-temperature sintered ore particles are blown onto the sealing cover, and the angle steel welded on the inner side of the sealing cover can effectively prevent most of the high-temperature particles from being blown onto the trolley guardrail, effectively reducing the damage of the high-temperature dusty exhaust gas to the rubber sheet.

[0022] In addition, from Figure 4It can be seen that the angle steel welded on the inner side of the sealing cover can form a buffer zone at the trolley guardrail, effectively reducing the hot exhaust gas flow rate at the trolley guardrail. It should be noted that there is a buffer distance between the angle steel and the inner plate of the trolley from the trolley guardrail, which is generally about 50mm in engineering, because the trolley with a cold machine will inevitably deviate to a certain extent during operation, but the deviation range will generally not exceed 50mm; this structural design ensures that even if the trolley with a cold machine deviates, the angle steel and the inner plate of the trolley will not be damaged by rigid collision.

[0023] The utility model also adds a primary sealing mechanism between the angle steel sealing mechanism and the rubber plate sealing mechanism, and the primary sealing mechanism includes a support fixedly installed on the inner lower part of the inner plate of the sealing cover and a hanging plate connected to the support. Figure 4-6 It can be seen that the hot exhaust gas entering between the angle steel and the inner side plate of the trolley can be blocked by the hanging plate of the initial sealing mechanism to prevent the hot exhaust gas from overflowing outside the trolley railing. Preferably, the initial sealing mechanism also includes a rotating shaft, and the hanging plate is movably connected to the support through the rotating shaft. The hanging plate of the initial sealing mechanism can swing with the rotating shaft, and the bottom of the hanging plate extends into the first sealing groove of the functional plate (the material is a steel plate). The bottom of the hanging plate squeezes the asbestos sealing layer in the first sealing groove to achieve better sealing. Another advantage of the initial sealing mechanism designed in this way is that the initial sealing mechanism is a rigid seal, the hanging plate is movable, and the trolley will not be damaged when it deviates, and the dynamic sealing effect can also be guaranteed. In addition, after the trolley is reset, the hanging plate will automatically reset under the action of its own gravity.

[0024] The utility model is designed with a rubber sealing mechanism on the outside of the primary sealing mechanism. The rubber sealing mechanism is structurally improved on the basis of the existing rubber plate sealing, the bottom of the rubber plate extends into the second sealing groove of the functional plate, and the bottom of the rubber plate squeezes the asbestos sealing layer in the second sealing groove to achieve better sealing. On the basis of the existing rubber plate, screw rod, fastening nut and other components, the rubber sealing mechanism of the utility model is additionally provided with asbestos pads, pressing steel plates and other components, wherein the screw rod can be welded to the inner plate of the sealing cover, and the asbestos pad is arranged between the rubber plate and the inner plate of the sealing cover, which can not only insulate and prevent the rubber plate from being burned by heat, but also improve the sealing performance. In addition, the pressing steel plate arranged between the rubber plate and the fastening nut can press the rubber plate to further improve the sealing performance.

[0025] The utility model has the following advantages by setting a functional plate between the trolley guardrail and the inner plate of the trolley: first, the structural design of the functional plate, such as the first sealing groove and the second sealing groove, cooperates with the hanging plate of the primary sealing mechanism and the rubber plate of the rubber sealing mechanism to achieve a sealing effect; preferably, the functional plate is tilted on the trolley guardrail, and a triangular heat-insulating cavity is formed between the functional plate, the trolley guardrail and the inner plate of the trolley, which ensures that the temperature of the functional plate will not be too high, and further ensures that the rubber plate will not be burned. It should be noted that the top elevation of the functional plate is slightly lower than the bottom elevation of the inner plate of the sealing cover. This design ensures that the two will not be damaged by rigid collision when the trolley deviates.

[0026] The utility model can effectively improve the sealing effect of the junction between the belt cooling machine trolley and the sealing cover, effectively reduce the air leakage rate, and improve the cooling effect of the sintered ore by designing the primary seal of the angle steel sealing mechanism, the secondary seal of the primary sealing mechanism, and the tertiary seal of the rubber plate.

[0027] In this application, the "inside" and "outside" are relative concepts in the width direction of the trolley, wherein the "inside" refers to the side close to the inside or center of the trolley, and the "outside" refers to the side away from the inside or center of the trolley. For example, the inside of the trolley guardrail is provided with a trolley inner plate, which means that the trolley inner plate is provided on the side of the trolley guardrail close to the inside of the trolley; the inside of the sealing cover is provided with a sealing cover inner plate, which means that the sealing cover is provided with a sealing cover inner plate on the side close to the inside of the trolley.

[0028] Compared with the prior art, the utility model has the following beneficial effects:

[0029] 1. On the basis of the existing rubber plate seal, the utility model adds an angle steel sealing mechanism, and a buffer zone is formed between the angle steel and the inner plate of the trolley guardrail, which effectively prevents most of the high-temperature particles in the trolley from being blown to the trolley guardrail. The existence of the buffer zone also effectively reduces the flow rate of hot exhaust gas at the trolley guardrail, thereby effectively reducing the damage of the rubber plate to the high-temperature dust-containing exhaust gas.

[0030] 2. The utility model adds a primary sealing mechanism between the angle steel sealing mechanism and the rubber plate sealing mechanism, and the hanging plate can swing with the rotating shaft, and the bottom of the hanging plate extends into the first sealing groove of the functional plate, and the bottom of the hanging plate squeezes the asbestos sealing layer in the first sealing groove to achieve better sealing. Moreover, the primary sealing mechanism is a rigid seal, and the hanging plate is movable, so it will not be damaged when the trolley deviates, and the dynamic sealing effect can be guaranteed. In addition, after the trolley is reset, the hanging plate will automatically reset under the action of its own gravity.

[0031] 3. The rubber sealing mechanism of the utility model has made structural improvements on the basis of the existing rubber plate sealing. The bottom of the rubber plate extends into the second sealing groove of the functional plate, and the bottom of the rubber plate squeezes the asbestos sealing layer in the second sealing groove to achieve better sealing. Moreover, the rubber sealing mechanism of the utility model has additional components such as asbestos pads and pressing steel plates. Among them, the asbestos pads arranged between the rubber plate and the inner plate of the sealing cover can not only insulate and prevent the rubber plate from being burned by heat, but also improve the sealing performance. The pressing steel plate arranged between the rubber plate and the fastening nut can press the rubber plate to further improve the sealing performance.

[0032] 4. The angle steel sealing mechanism and the primary sealing mechanism of the utility model are rigid seals, which can effectively block most of the heat, effectively protect the rubber sheet of the rubber sealing mechanism from being burned, and ensure that the soft seal of the rubber sheet can play a better effect. The utility model effectively improves the sealing effect of the junction between the belt cooling machine trolley and the sealing cover by designing the primary seal of the angle steel sealing mechanism, the secondary seal of the primary sealing mechanism, and the tertiary seal of the rubber sheet, effectively reduces the air leakage rate, and improves the cooling effect of the sintered ore.
