Description

Technical Field

[0001] This invention relates to the field of sealing structure technology, and specifically to an adjustable elastic sealing device. Background Technology

[0002] Currently, annular coolers generally use a pelletized design, with the lower seal employing three types: water seal, rubber seal, and elastic seal. Rubber seals are prone to aging and have a short lifespan. Water seals occupy a large space, have high manufacturing requirements, and the water tank welding must ensure a leak-proof seal. Operation also requires strict control of air pressure, as excessive air pressure can easily cause unstable water levels and vibrations in the tank. In contrast, elastic seals occupy less space, require less daily maintenance, and have a longer service life.

[0003] The existing elastic sealing structure has the following problems: 1) The sealing slide (i.e., the sealing element) and the fixed body are in sliding contact, which results in a certain amount of air leakage; 2) The elastic slide is only supported by springs, resulting in poor equipment stability; 3) The elastic sealing spring seat has no adjustment space, and the installation accuracy of the elastic sealing support is required during equipment installation. When the installation height error of the support is large, it will affect the spring compression. If the compression is too large, it will cause the running resistance of the ring cooler to be large and the slide will be easily worn. If the compression is too small, the slide and the bottom surface of the rotating frame cannot fit tightly, which will affect the sealing effect; 4) After the equipment has been running for a period of time, the spring compression will decrease as the slide wears. If it decreases to a certain extent and does not meet the sealing requirements, the entire set of equipment needs to be shut down and replaced, which increases costs and reduces production efficiency.

[0004] In summary, there is an urgent need for an adjustable elastic sealing device to solve the problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable elastic sealing device, which aims to overcome the shortcomings of existing elastic sealing structures. The specific technical solution is as follows: An adjustable elastic sealing device is used to achieve a seal between a first component and a second component that are in relative motion. The adjustable elastic sealing device includes a base, an intermediate adjusting seat, an elastic element, a flexible sealing element, a sliding sealing assembly, a guide assembly, and an adjusting assembly. The base, intermediate adjusting seat, and sliding sealing assembly are arranged sequentially, and a flexible sealing element is provided between the base and the sliding sealing assembly. A guide assembly and a compressed elastic element are provided between the intermediate adjusting seat and the sliding sealing assembly, and the sliding sealing assembly slides and seals with the first component. An adjusting assembly for adjusting the distance between the intermediate adjusting seat and the base is provided, and the base is fixed to the second component in a sealed installation manner.

[0006] Preferably, the adjustment assembly includes an adjustment screw and an adjustment nut. The intermediate adjustment seat has a through hole. The first end of the adjustment screw is disposed on the base, and the second end of the adjustment screw passes through the through hole. The adjustment nut is sleeved on the adjustment screw, and the adjustment nut is turned to adjust the distance between the base and the intermediate adjustment seat.

[0007] Preferably, the first end of the adjusting screw is fixedly mounted on the base, and adjusting nuts are fitted onto both sides of the through hole or on the side of the through hole closer to the base.

[0008] Preferably, the sliding sealing assembly includes a sealing seat and a sliding seal, a guide assembly and an elastic element are provided between the sealing seat and the intermediate adjusting seat, a flexible seal is provided between the sealing seat and the base, and the sliding seal is located on the side of the sealing seat away from the intermediate adjusting seat.

[0009] Preferably, the flexible seal is disposed on the side close to the first component and the second component.

[0010] Preferably, the elastic element is sleeved on the guide assembly between the sliding sealing assembly and the intermediate adjusting seat.

[0011] Preferably, a guide assembly is also provided between the base and the intermediate adjustment seat; The guiding assembly includes a guide rod and a guide sleeve, the guide sleeve being fitted onto the guide rod and the two being able to move relative to each other.

[0012] Preferably, the guide assembly or adjustment assembly between the intermediate adjustment seat and the base is arranged coaxially with the guide assembly between the sliding sealing assembly and the intermediate adjustment seat.

[0013] Preferably, the adjustable elastic sealing device is used to circumferentially seal between the first component and the second component, wherein the base, intermediate adjusting seat, flexible sealing element and sliding sealing assembly are all arranged circumferentially; and the elastic element, guiding assembly and adjusting assembly are all spaced apart circumferentially.

[0014] Preferably, the first component is the rotating frame of the annular cooler, and the second component is the air duct component of the annular cooler. The adjustable elastic sealing device is provided on both the inner and outer sides of the rotating frame and the air duct component.

[0015] The application of the technical solution of the present invention has the following beneficial effects: The adjustable elastic sealing device of the present invention provides elastic force through a compressed elastic element to maintain continuous contact between the sliding sealing assembly and the first component. By adjusting the position of the intermediate adjusting seat through the adjusting assembly, i.e., adjusting the compression of the elastic element, the contact pressure between the sliding sealing assembly and the first component reaches the optimal value, reducing the operating resistance of the annular cooler and the wear rate of the sliding seal. When the equipment has been used for a period of time, as the sliding seal wears, if the compression of the elastic element is insufficient to meet the sealing requirements, the adjusting nut can be adjusted without stopping the machine to increase the compression of the elastic element, thereby improving service life and reducing maintenance costs. In addition, since the compression of the elastic element can be adjusted through the adjusting assembly, the adjustable elastic sealing device of the present invention can effectively reduce the precision requirements for manufacturing and installation, and reduce manufacturing and installation costs.

[0016] The adjustable elastic sealing device of the present invention is equipped with a guide component to ensure the stability of the relative movement between the base, the intermediate adjustment seat and the sliding sealing component, which can effectively prevent the movement from getting stuck; the flexible seal connects the base and the sliding sealing component, so that the adjustable elastic sealing device of the present invention itself does not leak air, thus improving the equipment's performance.

[0017] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0019] To facilitate understanding of the present invention, a more complete description is provided below, along with preferred embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] Example: The trolley of the annular cooler carries the sinter 1 in a circular motion to achieve the purpose of cooling the sinter 1. During the operation of the annular cooler, there will be relative movement between the rotating frame 2 of the trolley and the air duct component 4. In order to ensure the normal operation of the annular cooler, it is necessary to seal between the rotating frame 2 and the air duct component 4 to prevent cooling air leakage. To this end, this embodiment provides an adjustable elastic sealing device, which is respectively set on the inner and outer sides of the rotating frame 2 and the air duct component 4 to meet the sealing requirements between the rotating frame 2 and the air duct component 4. In this embodiment, the first component refers to the rotating frame 2 and the second component refers to the air duct component 4.

[0022] See Figures 1-4 The adjustable elastic sealing device includes a base 5, an intermediate adjusting seat 8, an elastic element 9, a flexible sealing element 14, a sliding sealing assembly, a guide assembly, and an adjusting assembly. The base 5, the intermediate adjusting seat 8, and the sliding sealing assembly are arranged sequentially. A flexible sealing element 14 is provided between the base 5 and the sliding sealing assembly. A guide assembly and a compressed elastic element 9 are provided between the intermediate adjusting seat 8 and the sliding sealing assembly. The sliding sealing assembly slides and seals with the first component. An adjusting assembly for adjusting the distance between the intermediate adjusting seat 8 and the base 5 is provided. The base 5 is fixed to the second component in a sealed installation manner.

[0023] like Figure 1 and Figure 3 As shown, a sliding seal is formed between the sliding sealing assembly and the first component, and a fixed seal is formed between the base 5 and the second component. The sliding sealing assembly and the base 5 are sealed by a flexible sealing element 14. Therefore, the gap between the first component and the second component is completely sealed. The adjustable elastic sealing device of this embodiment can meet the sealing requirements between the first component and the second component without affecting the relative movement of the first component and the second component.

[0024] like Figure 3As shown, the adjusting assembly includes an adjusting screw 6 and an adjusting nut 7. The intermediate adjusting seat 8 has a through hole. The first end of the adjusting screw 6 is mounted on the base 5, and its second end passes through the through hole. The adjusting nut 7 is sleeved on the adjusting screw 6. Tightening the adjusting nut 7 adjusts the distance between the base 5 and the intermediate adjusting seat 8. Here, the first end and the second end of the adjusting screw 6 refer to the two ends of the adjusting screw 6.

[0025] Furthermore, the first end of the adjusting screw 6 is fixedly mounted on the base 5, ensuring that the adjusting screw 6 will not deviate and preventing the guide component between the sliding sealing assembly and the intermediate adjusting seat 8 from jamming. Even further, adjusting nuts 7 are fitted on both sides of the through hole of the adjusting screw 6, and both adjusting nuts 7 press against the intermediate adjusting seat 8, thereby securing the adjusting screw 6 and the intermediate adjusting seat 8 together. It should be noted that since the elastic element 9 is in a compressed state, the adjusting nut 7 can be provided only on the side of the through hole closest to the base 5, and the distance between the base 5 and the intermediate adjusting seat 8 can be adjusted by turning the adjusting nut 7.

[0026] Preferably, the compressed elastic element 9 provides elastic force to ensure that the sliding sealing assembly always maintains contact with the first component, thereby forming an effective sliding seal. When wear causes the sliding sealing assembly to lose continuous contact with the first component, resulting in seal failure, the adjusting nut 7 can be turned to move the intermediate adjusting seat 8 towards the first component, i.e., reduce the distance between the intermediate adjusting seat 8 and the first component, thereby adjusting the compression of the elastic element 9 and allowing the sliding sealing assembly to re-form a good sliding seal with the first component. Since the intermediate adjusting seat 8 is sleeved on the adjusting screw 6 through a through hole, the cooperation between the through hole and the adjusting screw 6 can provide a certain constraint on the movement adjustment of the intermediate adjusting seat 8, ensuring that the intermediate adjusting seat 8 moves along the axial direction. Furthermore, in this embodiment, the elastic element 9 is a spring.

[0027] See Figure 3 and Figure 4 The sliding sealing assembly includes a sealing seat 12 and a sliding seal 13. A guide component and an elastic element 9 are provided between the sealing seat 12 and the intermediate adjusting seat 8. A flexible seal 14 is provided between the sealing seat 12 and the base 5. The sliding seal 13 is located on the side of the sealing seat 12 away from the intermediate adjusting seat 8, and a sliding seal is formed between the sliding seal 13 and the first component. Preferably, the sliding seal 13 is detachably installed on the sealing seat 12 to facilitate future maintenance and replacement of the sliding seal 13.

[0028] Preferably, the flexible seal 14 is disposed on the side close to the first component and the second component. This arrangement allows for easy adjustment of the distance between the intermediate adjustment seat 8 and the base 5 via the adjustment assembly, without the need to disassemble the flexible seal 14.

[0029] like Figure 3 As shown, the elastic element 9 is sleeved on the guide assembly between the sliding sealing assembly and the intermediate adjusting seat 8, thereby ensuring that the movement direction of the elastic element is parallel to the movement direction of the guide assembly, and ensuring the smooth movement between the sliding sealing assembly and the intermediate adjusting seat 8.

[0030] Furthermore, although the cooperation between the through hole and the adjusting screw 6 can play a certain role in constraining and guiding the movement between the base 5 and the intermediate adjusting seat 8, in order to ensure the stability of the movement adjustment, a guiding component is also provided between the base 5 and the intermediate adjusting seat 8 in this embodiment. By providing guiding components between the base 5 and the intermediate adjusting seat 8 and between the intermediate adjusting seat 8 and the sliding sealing component, it can be ensured that the two adjacent components move relative to each other in the vertical direction, thus avoiding the occurrence of movement jamming.

[0031] Preferably, the guiding assembly includes a guide rod and a guide sleeve. The guide rod is disposed on one of the relatively moving components, and the guide sleeve is disposed on the other relatively moving component. The guide sleeve is fitted onto the guide rod, and the two components are capable of relative movement. Specifically, in this embodiment, the guiding assembly between the sliding sealing assembly and the intermediate adjusting seat 8 includes an upper guide sleeve 10 and an upper guide rod 11. The upper guide rod 11 is disposed on the sealing seat 12, the upper guide sleeve 10 is disposed on the intermediate adjusting seat 8, and the upper guide sleeve 10 is fitted onto the upper guide rod 11. The elastic element 9 is fitted onto the outside of the upper guide sleeve 10. The guiding assembly between the base 5 and the intermediate adjusting seat 8 includes a lower guide sleeve 15 and a lower guide rod 16. The lower guide sleeve 15 is disposed on the base 5, the lower guide rod 16 is disposed on the intermediate adjusting seat 8, and the lower guide sleeve 15 is fitted onto the lower guide rod 16.

[0032] Preferably, the guide assembly or adjustment assembly between the intermediate adjustment seat 8 and the base 5 is arranged coaxially with the guide assembly between the sliding sealing assembly and the intermediate adjustment seat 8. This arrangement ensures that the relative movement between the base 5, the intermediate adjustment seat 8, and the sliding sealing assembly will not be hindered. Of course, those skilled in the art can also use other arrangements.

[0033] Furthermore, since the adjustable elastic sealing device in this embodiment is used to perform circumferential sealing between the first component and the second component, the base 5, the intermediate adjusting seat 8, the flexible sealing element 14 and the sliding sealing assembly are all arranged circumferentially, that is, the base 5, the intermediate adjusting seat 8, the flexible sealing element 14 and the sliding sealing assembly are all annular parts; wherein, the elastic element 9, the guide assembly and the adjusting assembly are all arranged circumferentially at intervals to ensure that there is no problem of movement jamming during adjustment.

[0034] like Figure 1 As shown, the second component (i.e., the air duct component 4) is provided with a mounting bracket 3. The mounting bracket 3 is also a ring-shaped part. The mounting bracket 3 is welded to the outer wall of the second component, so there will be no air leakage between the mounting bracket 3 and the second component. The base 5 is fixed to the mounting bracket 3 in a sealed installation method. The sealed installation method can be welding or bolt assembly with sealing gasket.

[0035] Preferably, in addition to sealing the rotating frame 2 and the air duct component 4, the adjustable elastic sealing device in this embodiment can also be used for sealing other structures with relative motion, such as sealing the upper baffle of the annular cooler and the annular cooler cover. Furthermore, the adjustable elastic sealing device in this embodiment is not limited to sealing annular structures; it can also be used to meet the sealing requirements of linear and non-linear structures, simply by matching the shape of the adjustable elastic sealing device to the shape of the structure requiring sealing.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
