Description

Technical Field

[0001] This invention belongs to the technical field of grate coolers, specifically relating to connection structures, and more particularly to a connection mechanism for a wind chamber, an installation method for the connection mechanism, and a grate cooler. Background Technology

[0002] The bottom of the grate cooler needs to be equipped with several air chambers to cool the material on the grate cooler through high-pressure cooling air. Since the material piled up on the grate cooler is more concentrated in the middle than at the edges, in order to dissipate heat evenly, the air intake of the middle air chamber needs to be greater than that of the two side air chambers.

[0003] In order to make the air intake of the air chamber adjustable, an air volume adjustment plate is installed on the air chamber body, and the air volume adjustment plate is connected to the air chamber body by the cooperation of connecting bolts and connecting nuts. The high-pressure cooling air will impact the air volume adjustment plate and generate vibration, which can easily cause the connecting nuts to loosen over time.

[0004] In related technologies, in order to reduce the loosening of the connecting nut, a washer is placed on the connecting bolt to increase the friction surface and reduce the loosening of the connecting nut.

[0005] However, conventional gaskets only have two friction surfaces, and even if two gaskets are used, the effective friction surface cannot be increased.

[0006] Therefore, how to solve the technical problem of not being able to increase the effective friction surface of the gaskets when using two gaskets is a problem that urgently needs to be solved by those skilled in the art.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] like Figure 1 As shown, at least one embodiment provides a connecting mechanism for a wind chamber, including: a wind chamber body 1 and an air volume regulating plate 2 slidably disposed on the outside of the wind chamber body 1, wherein the air volume regulating plate 2 and the wind chamber body 1 are connected by connecting bolts 3 and connecting nuts 4.

[0029] like Figures 1 to 4 As shown, in some embodiments, a first washer 5 and a second washer 6 are provided between the connecting nut 4 and the air volume regulating plate 2. The first washer 5 is fixedly connected to the connecting nut 4, and the second washer 6 is rotatably connected to the air volume regulating plate 2. Both the first washer 5 and the second washer 6 have an engagement portion 51, and the two engagement portions 51 are arranged facing each other. When the connecting nut 4 is tightened, the first washer 5 presses against the second washer 6 and the two engagement portions 51 cross-fit each other to increase the friction surface.

[0030] In this embodiment, by providing a first washer 5 and a second washer 6 with an engagement portion 51, and fixing the first washer 5 to the connecting nut 4, and rotating the second washer 6 to the airflow regulating plate 2, the engagement portions 51 of the first washer 5 and the second washer 6 cross-fit each other when the connecting nut 4 is tightened, thereby increasing the friction surface to prevent loosening.

[0031] like Figure 4 As shown, in some embodiments, both the first gasket 5 and the second gasket 6 have annular mounting portions 52; wherein the interlocking portion 51 is inclined, one end of the interlocking portion 51 is connected to the annular mounting portion 52, and the other end of the interlocking portion 51 is away from the annular mounting portion 52.

[0032] like Figure 5 As shown, in some embodiments, the biting portion 51 is arc-shaped, and the central angle α corresponding to the projection of the biting portion 51 onto the annular mounting portion 52 is in the range of 115°-175°.

[0033] like Figure 6 As shown, in some embodiments, the distance between the end of the engaging portion 51 away from the annular mounting portion 52 and the annular mounting portion 52 is L; the pitch of the connecting nut 4 is P; wherein, L≥1.5P.

[0034] In this embodiment, the upward tilting height L of the engagement portion 51 is ≥1.5P, which is to ensure that during the tightening process, the engagement portion 51 of the first washer 5 on the connecting nut 4 is inserted into the engagement portion 51 of the second washer 6.

[0035] like Figure 6 As shown, in some embodiments, the annular mounting portion 52 is divided into a right half-circle 521 and a left half-circle 522; the projection of the biting portion 51 is located within the right half-circle 521; the thickness of the right half-circle 521 is H1, the thickness of the left half-circle 522 is H2, and the thickness of the biting portion 51 is H3; wherein, H1+H3=H2.

[0036] Specifically, the right half-circle 521 and the left half-circle 522 are not both 180°. When the biting part 51 is under force and fits against the annular mounting part 52, the biting part 51 covers the right half-circle 521.

[0037] That is, when the occlusal portion 51 becomes longer, the right half-circle 521 becomes longer and the left half-circle 522 becomes shorter.

[0038] In this embodiment, the thickness is set to H1+H3=H2 to ensure that the first washer 5 and the second washer 6 are fully fitted when the connecting nut 4 is tightened.

[0039] like Figure 7As shown, in some embodiments, the air chamber body 1 has a first waist-shaped hole 11 and the air volume regulating plate 2 has a second waist-shaped hole 21; wherein the connecting bolt 3 passes through the first waist-shaped hole 11 and the second waist-shaped hole 21 in sequence.

[0040] like Figure 7 As shown, in some embodiments, the outer wall of the air volume regulating plate 2 is provided with a pair of limiting grooves 22 around the second waist-shaped hole 21; wherein the annular mounting part 52 of the second gasket 6 is rotatably limited within the limiting grooves 22.

[0041] like Figure 8 As shown, in some embodiments, in the first gasket 5, the width of the annular mounting portion 52 is the same as the width of the biting portion 51; in the second gasket 6, the width of the annular mounting portion 52 is greater than the width of the biting portion 51.

[0042] Specifically, both the first gasket 5 and the second gasket 6 have a certain degree of elasticity; during installation, the second gasket 6 undergoes elastic deformation to insert both sides of its annular mounting portion 52 into the limiting groove 22.

[0043] In this embodiment, the width of the annular mounting portion 52 of the second gasket 6 is greater than the width of the interlocking portion 51 of the second gasket 6; wherein, support platforms 23 for supporting the second gasket 6 are provided on both sides of the second waist-shaped hole 21, and limit grooves 22 are formed on the side walls of the support platforms 23, so that the portion of the annular mounting portion 52 protruding from the interlocking portion 51 extends into the limit groove 22, thereby realizing the rotation limit of the second gasket 6.

[0044] At least one embodiment also provides a method for installing a connecting mechanism for a wind chamber, comprising: passing a connecting bolt 3 through the wind chamber body 1 and the air volume regulating plate 2; connecting a connecting nut 4 to the connecting bolt 3 to lock the air volume regulating plate 2, and when the connecting nut 4 is locked, causing the engaging portion 51 of the first washer 5 on the connecting nut 4 to cross-fit with the engaging portion 51 of the second washer 6 on the air volume regulating plate 2 to increase the friction surface.

[0045] For details on the specific structure and implementation process of the connecting mechanism for the air chamber, please refer to the relevant discussion in the above embodiments, which will not be repeated here.

[0046] like Figure 9 As shown, at least one embodiment also provides a grate cooler, including: a connecting mechanism for the air chamber.

[0047] For details on the specific structure and implementation process of the connecting mechanism for the air chamber, please refer to the relevant discussion in the above embodiments, which will not be repeated here.

[0048] In summary, the connecting mechanism for this air chamber, the installation method of the connecting mechanism, and the grate cooler are provided with a first gasket 5 and a second gasket 6 having an interlocking part 51. The first gasket 5 is fixedly connected to the connecting nut 4, and the second gasket 6 is rotatably connected to the air volume regulating plate 2. Thus, when the connecting nut 4 is locked, the interlocking parts 51 of the first gasket 5 and the second gasket 6 are cross-fitted with each other, thereby increasing the friction surface to prevent loosening.
