Description

Technical Field

[0001] The utility model relates to the technical field of sintering production equipment, in particular to an adaptive sealing structure of a trolley and a bellows and the sintering equipment. Background Art

[0002] In industrial production processes such as sintering, roasting, and cooling, key equipment such as sintering machines, roasting machines, and coolers are commonly equipped with bellows and trolley systems. In these devices, the trolley is designed to be positioned above the bellows and can reciprocate along a pre-set track above the bellows to achieve efficient material handling. However, in actual operation, a certain gap inevitably exists between the bottom of the trolley and the top of the bellows due to design or manufacturing requirements. This gap not only causes a large amount of air leakage, resulting in significant energy waste and reduced production efficiency, but also the airflow noise generated during the air leakage causes noise pollution to the surrounding environment, affecting the quality of the work environment and the health of employees.

[0003] To address these issues and ensure the efficient operation of the blower system, the key lies in effectively sealing the gap between the bottom of the trolley and the bellows to prevent air from escaping this vulnerable link. Currently, a variety of sealing structures have been proposed and applied to this type of equipment, aiming to achieve gap sealing through physical means. However, these sealing structures still face numerous challenges in practical application. For example, over the long-term operation of the equipment, seals gradually fail due to wear, resulting in a decrease in sealing performance. Furthermore, due to errors during the installation process, the gap between the trolley and the bellows may be uneven, which adds additional difficulties to the sealing work.

[0004] Therefore, how to design a sealing structure that can automatically adapt to gap changes caused by seal wear or installation errors has become an urgent problem to be solved. Utility Model Content

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] The purpose of the utility model is to provide an adaptive sealing structure of a trolley and a bellows and a sintering device to solve the problems existing in the prior art. A sealing method in which a U-shaped flexible sealing strip is matched with a square tube seat is adopted to ensure the sealing effect. At the same time, pressure compensation of the sealing surface is provided with the help of a spring, which can adapt to changes in the gap between the sealing surfaces and significantly improve the sealing performance of the equipment.

[0049] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0050] like Figures 1 to 17As shown, the utility model provides an adaptive sealing structure for a trolley and a bellows, including a U-shaped flexible sealing strip 31, a square tube seat 32 and a spring 36. Compared with a rigid sealing strip, the U-shaped flexible sealing strip 31 has better conformal sealing performance and a single strip can be longer. The U-shaped flexible sealing strip 31 includes a sealing strip body 314 and a sealing strip side wall 315 connected to the sealing strip body 314. The sealing strip body 314 is long and the sealing strip side wall 315 is connected to both sides of the sealing strip body 314 to form a U-shaped structure as a whole. It should be noted that the connection mentioned here is only a description of the positional relationship, and can be, but is not limited to, an integral molding of the sealing strip body 314 and the sealing strip side wall 315. The outer bottom surface of the sealing strip body 314 is used to seal with the sealing slide 11 installed at the bottom of the trolley 1. The sealing slide 11 moves with the trolley 1 and extends along the length direction of the trolley 1. The length direction of the trolley 1 is also the direction of travel of the trolley 1. The sealing strip body 314 is in contact and sealed with the sealing slide 11. The square tube seat 32 is used to be fixedly installed on the bottom plate 23 fixed to the side plate 24 of the bellows 2. The U-shaped flexible sealing strip 31 is upside down on the square tube seat 32. There is a gap between the top surface of the square tube seat 32 and the inner bottom surface of the sealing strip body 314, so that the sealing strip body 314 can float up and down within a certain range. The side surface of the square tube seat 32 is in sealing contact with the inner wall surface of the sealing strip side wall 315 (using the elasticity of the sealing strip side wall 315 itself to clamp on both side surfaces of the square tube seat 32) to ensure that when the sealing strip body 314 floats up and down, the sealing strip side wall 315 is always in contact and sealed with the square tube seat 32. The spring 36 is a high-temperature resistant spring 36. The top end of the spring 36 is connected to the inner bottom surface of the sealing strip body 314, and the bottom end of the spring 36 is connected to the square tube seat 32. The spring 36 is used to provide an extrusion force for the sealing strip body 314 toward the sealing slide 11 to maintain a good seal between the sealing strip body 314 and the sealing slide 11. Therefore, under the support of the spring 36, the contour seal of the U-shaped flexible sealing strip 31 is achieved.

[0051] The utility model adopts a sealing method in which a U-shaped flexible sealing strip 31 cooperates with a square tube seat 32, utilizes a sealing connection between the sealing strip body 314 and the sealing slide 11 at the bottom of the trolley 1, and utilizes a sealing connection between the sealing strip side wall 315 and the square tube seat 32 to ensure the sealing effect. At the same time, with the help of the spring 36, pressure compensation is provided on the sealing surface between the sealing strip body 314 and the sealing slide 11, and when the sealing strip body 314 is moved, the sealing connection between the sealing strip side wall 315 and the square tube seat 32 is always maintained, which can adapt to changes in the sealing surface gap between the sealing strip body 314 and the sealing slide 11, and significantly improve the sealing performance of the equipment.

[0052] like Figures 4 to 7As shown in the figure, the position is the position with the best sealing effect for factory products and on-site installation. At this time, the U-shaped flexible sealing strip 31 can float within a certain range up and down. During operation, it can be ensured that the sealing surface of the trolley 1 rises by 10 mm and falls by 15 mm, achieving the effect of contour sealing.

[0053] In one embodiment, if Figure 13 and Figure 14 As shown, it also includes a tensioning seat plate 35, which is fixedly connected to the inner bottom surface of the sealing strip body 314. The top of the spring 36 abuts the tensioning seat plate 35. The tensioning seat plate 35 can be arranged along the length direction of the sealing strip body 314 to be able to tighten the entire sealing strip body 314. On the one hand, it is convenient to install the U-shaped flexible sealing strip 31, and avoid the situation where the spring 36 directly abuts the sealing strip body 314, which causes the sealing strip body 314 to be soft and unable to achieve overall sealing. On the other hand, after connecting the tensioning rod 351, it is convenient to adjust the floating range of the sealing strip body 314.

[0054] In one embodiment, if Figure 7 and Figure 10 As shown, the sealing strip body 314 is provided with embedded parts 311. The embedded parts 311 are rigid components (e.g., steel plates) and are spaced apart along the length of the sealing strip body 314. The tensioning seat plate 35 is provided with screw holes 352 (the embedded parts 311 are tapped to form the screw holes 352 before the U-shaped flexible sealing strip 31 is formed, and the embedded parts 311 are placed in a set position to ensure a firm and reliable bond with the sealing strip body 314). The screws penetrate the tensioning seat plate 35 and connect to the threaded holes in the embedded parts 311, thereby connecting the tensioning seat plate 35 to the embedded parts 311. The provision of the embedded parts 311 can enhance the connection strength between the tensioning seat plate 35 and the U-shaped flexible sealing strip 31.

[0055] In one embodiment, if Figures 15 to 17 As shown, the inner bottom surface of the sealing strip body 314 is provided with protrusions 3141. The protrusions 3141 are arranged at intervals along the length of the sealing strip body 314, and one or more protrusions 3141 can be provided along the width of the sealing strip body 314 according to the actual size. The tensioning seat plate 35 is provided with an opening, and the protrusions 3141 are snapped into the opening to securely connect the sealing strip body 314 to the tensioning seat plate 35. It should be noted that the connection method of the protrusions 3141 and the opening, and the connection method of the embedded part 311, the screw, and the screw hole 352 can be used simultaneously or separately.

[0056] In one embodiment, if Figure 11As shown, it also includes a structural reinforcement 316, which is arranged inside the sealing strip body 314 to increase the strength of the U-shaped flexible sealing strip 31. The structural reinforcement 316 adopts a rigid component (such as a steel plate). The structural reinforcement 316 can be used to increase the strength of the U-shaped flexible sealing strip 31.

[0057] In one embodiment, if Figure 11 As shown, the structural reinforcement 316 is located on the side of the embedded part 311 close to the trolley 1. The structural reinforcement 316 can also contact and seal with the sealing slide 11 at the bottom of the trolley 1 after the sealing strip body 314 is worn to ensure the sealing effect. The thickness of the structural reinforcement 316 is 1.5mm~2.5mm. If it is too thick, it will affect the contour sealing of the U-shaped flexible sealing strip 31 and the sealing slide 11 at the bottom of the trolley 1. If it is too thin, it will have no strength and wear quickly.

[0058] In one embodiment, the length of the structural reinforcement member 316 is shorter than that of the U-shaped flexible sealing strip 31 , mainly because a position for the end connector 313 is reserved.

[0059] In one embodiment, if Figure 6 、 Figure 13 and Figure 14 As shown, the assembly further includes a tension rod 351. The top of the tension rod 351 is connected to the tension base plate 35 by welding or other means. The bottom of the tension rod 351 extends through the square tube base 32 and the base plate 23. An adjustment nut is threadedly connected to the portion extending beyond the base plate 23. By turning the adjustment nut, the tension of the tension rod 351 on the tension base plate 35 can be adjusted, thereby adjusting the floating range of the U-shaped flexible sealing strip 31.

[0060] The tensioning seat plate 35 is the reference position to ensure the design of the product before leaving the factory and on-site installation. The height dimension in the drawing must be maintained after the product leaves the factory and the installation is completed. Before the on-site trial run, the adjusting nut on the tensioning rod 351 of the tensioning seat plate 35 needs to be adjusted downward by 15mm to ensure the running clearance for the up and down movement.

[0061] In one embodiment, if Figure 5 As shown, it also includes a clamping rod 37, the top end of the clamping rod 37 and the bottom end of the spring 36 are both located in the inner cavity of the square tube seat 32, the top end of the clamping rod 37 abuts the bottom end of the spring 36, and the top end of the clamping rod 37 can also be provided with an enlarged end or a gasket, the width of the enlarged end and the gasket is larger than the diameter range of the spring 36, to achieve stable abutment against the spring 36, that is, when the clamping rod 37 moves, the compression degree of the spring 36 can be adjusted, thereby achieving the adjustment of the degree of fit of the U-shaped flexible sealing strip 31 to the sealing slide 11. The clamping rod 37 is threadedly connected to the bottom surface or bottom plate 23 of the square tube seat 32, and its axial position is adjusted by rotating the clamping rod 37. The end of the clamping rod 37 can be provided with a square head for easy adjustment.

[0062] The pressing rod 37 is used to adjust the pressure of the spring 36. After starting up and during operation, observe the operating conditions and adjust the ideal height of the pressing rod 37 in time.

[0063] In one embodiment, if Figures 4 to 6 As shown, the upper steel plate 321 is also included. The upper steel plate 321 is connected to the top surface of the square tube seat 32. The square tube seat 32 is made of steel plate. The upper steel plate 321 and the square tube seat 32 can be connected by welding, riveting, bolting, etc. The portion of the upper steel plate 321 that extends beyond the square tube seat 32 in the width direction forms an outer flange. The inner wall surface of the sealing strip side wall 315 protrudes inward to form an inner flange. The inner flange is located below the outer flange. The outer flange serves as a limiter for the inner flange, preventing the U-shaped flexible sealing strip 31 from detaching upward from the square tube seat 32.

[0064] In one embodiment, if Figures 4 to 6 As shown, the lower steel plate 322 is also included. The lower steel plate 322 is connected to the bottom surface of the square tube seat 32. The square tube seat 32 is made of steel. The lower steel plate 322 and the square tube seat 32 can be connected by welding, riveting, bolting, etc. The lower steel plate 322 is located between the square tube seat 32 and the bottom plate 23. The purpose of the lower steel plate 322 is to increase the strength of the square tube seat 32. If the tube wall of the square tube seat 32 is thin (less than 5 mm thick), the lower steel plate 322 is required. If the tube wall thickness meets the standard, the lower steel plate 322 is not required.

[0065] In one embodiment, if Figures 4 to 6 As shown, a thermal insulation layer 33 is provided between the lower steel plate 322 and the base plate 23. The thermal insulation layer 33 can be made of asbestos padding, which has different thicknesses, such as 3 mm and 5 mm. Fixing bolts 34 pass through the base plate 23, the thermal insulation layer 33, and the lower steel plate 322, and extend into the square tube seat 32, thereby securing the square tube seat 32 to the base plate 23.

[0066] In one embodiment, if Figure 8 、 Figure 9 and Figure 12 As shown, it also includes an end connector 313, which has dovetail blocks set on both sides. A dovetail groove 312 is opened at the end of the sealing strip body 314. The dovetail block is used to be clamped in the dovetail groove 312 of the adjacent sealing strip body 314 to achieve docking connection of different U-shaped flexible sealing strips 31, thereby increasing the length of the U-shaped flexible sealing strip 31 while ensuring the connection strength.

[0067] In one embodiment, the material of the U-shaped flexible sealing strip 31 is high-temperature resistant, wear-resistant, and corrosion-resistant rubber. The length of the U-shaped flexible sealing strip 31 is greater than 2m. When the end connector 313 is used for connection, the connection gap can be firmly bonded with 701 glue (the main component is ethyl cyanoacrylate adhesive, commonly known as quick-drying glue, instant glue. Unique feature: it has excellent adhesion to TPU, TPR, and TPE materials).

[0068] Recombination Figures 1 to 17 As shown, the utility model also provides a sintering device, including the adaptive sealing structure 3 as described above, the outer bottom surface of the sealing strip body 314 is in sealing contact with the sealing slide 11 at the bottom of the trolley 1, and the square tube seat 32 is fixedly installed on the bottom plate 23 fixed to the side plate 24 of the bellows 2.

[0069] In one embodiment, if Figures 4 to 7 As shown, a heat insulation component is provided near the top of the side panel 24 of the bellows 2, and the heat insulation component includes a shell 21 with a cavity. The shell 21 is installed on the back panel 25, and the back panel 25 is provided near the top of the side panel 24. The shell 21 is filled with heat insulation material 22, such as ceramic insulation cotton. The function of the heat insulation component is to insulate so that there is no direct contact between the side panel 24 and the U-shaped flexible sealing strip 31. The U-shaped flexible sealing strip 31 is generally made of rubber material. High temperature will cause the sealing performance to decline or reduce the service life. The setting of the heat insulation component can prevent high temperature from damaging the U-shaped flexible sealing strip 31.

[0070] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
