Description

Technical Field

[0001] This application belongs to the field of dry quenching technology, specifically relating to a dry quenching dust cover support arm and a loading device. Background Technology

[0002] Dry quenching (CDQ) is an advanced coke cooling technology. Compared with traditional wet quenching (cooling coke by spraying water), dry quenching uses an inert gas (usually nitrogen) to circulate and cool the red-hot coke, resulting in significant energy-saving, environmental protection, and economic benefits.

[0003] Dry quenching technology is currently the most widely used and energy-efficient coke quenching technology in the coking industry. However, when coke is loaded into the dry quenching furnace, dust leakage must be prevented to meet environmental requirements. The dust cover needs to be able to be pressed open simultaneously when the coke can is being loaded downwards; and also needs to be able to rebound and close when the coke can is being loaded upwards.

[0004] Each time coke is loaded, the dust cover is pressed down on the coke can, and it springs back when the can is lifted out of the coke can. This frequent pressing and rebounding causes stress cracking at the weld between the support arm and the dust cover, making the dust cover prone to detachment and disrupting normal production. Currently, the support arm and dust cover only have single-sided contact, with only two welds on one side, and these welds are short, resulting in weak support strength. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application discloses a dry quenching coke loading dust cover support arm.

[0006] The technical solution adopted to achieve the purpose of this application is as follows: In the first aspect of this application, this utility model discloses a dry quenching coke loading dust cover support arm, including a first support part and a second support part. The first support part and the second support part are inclinedly arranged. A connecting groove is provided on the first support part. One end of the connecting groove away from the second support part extends to the end face of the first support part, and the connecting groove penetrates the first support part along the width direction of the first support part. An installation hole is provided at the connection between the first support part and the second support part, and a connecting hole is provided on the second support part.

[0007] In some embodiments, the first support portion includes a connecting block, a front end plate, and a rear end plate. The connecting block is connected to the second support portion, and the front end plate and the rear end plate are spaced apart at one end of the connecting block away from the second support portion to form the connecting groove.

[0008] In some embodiments, at least one of the front-end board and the rear-end board has a length greater than or equal to 300 mm.

[0009] In some embodiments, the length of both the front-end board and the rear-end board is set to 300mm.

[0010] In some embodiments, a bearing is also included, which is mounted within the mounting hole.

The dust cover plate is inserted into the connecting groove, and the mounting hole is connected to the support lug of the loading hopper.

[0014] In some embodiments, both sides of the dust cover are welded to the first support portion.

[0015] In some embodiments, the width of the connecting groove is greater than the thickness of the dust cover.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] This utility model embodiment discloses a dry quenching coke loading dust cover support arm, which can solve the technical problem of easy cracking of the weld joint of the existing support arm, thereby improving the stability and service life of the dust cover 300 and ensuring the normal operation of production.

[0027] The technical solution of this application will be described in detail below through specific embodiments:

[0028] See Figure 1 and Figure 2 In a first aspect embodiment of this application, a dry quenching coke loading dust cover support arm is disclosed, which includes a first support portion 100 and a second support portion 200. The first support portion 100 and the second support portion 200 are inclined. A connecting groove 110 is provided on the first support portion 100. One end of the connecting groove 110 away from the second support portion 200 extends to the end face of the first support portion 100, and the connecting groove 110 penetrates the first support portion 100 along the width direction. A mounting hole 210 is provided at the connection between the first support portion 100 and the second support portion 200, and a connecting hole 220 is provided on the second support portion 200.

[0029] The dry quenching coke loading dust cover support arm disclosed in this embodiment forms an abutment with both sides of the dust cover 300 through the connecting groove 110, changing the connection between the dust cover 300 and the first support part 100 from traditional spot welding or line welding to surface contact. This contact method effectively disperses the stress generated during welding, significantly reducing the risk of weld cracking due to stress concentration.

[0030] The design of the connecting groove 110 extending to the end face of the first support 100 and running through the width direction allows the dust cover 300 to be inserted quickly and accurately. This structure reduces the difficulty of installation, shortens operation time, and improves work efficiency.

[0031] In one embodiment, the first support portion 100 includes a connecting block 120, a front end plate 130, and a rear end plate 140. The connecting block 120 is connected to the second support portion 200, and the front end plate 130 and the rear end plate 140 are spaced apart at one end of the connecting block 120 away from the second support portion 200 to form a connecting groove 110.

[0032] The connection between the connecting block 120 and the second support 200, along with the spacing between the front plate 130 and the rear plate 140 at the end of the connecting block 120 away from the second support 200, forms a stable connecting groove 110. This design allows the dust cover 300 to be firmly inserted into the connecting groove 110, improving the stability and reliability of the connection and reducing the risk of the dust cover 300 falling off due to vibration or impact during use.

[0033] The combined structure of the connecting block 120, the front end plate 130, and the rear end plate 140 allows the support arm to maintain sufficient strength while achieving a more compact structure. This design helps reduce the weight and cost of the equipment and improves its overall performance.

[0034] In one embodiment, at least one of the front-end board 130 and the rear-end board 140 has a length greater than or equal to 300 mm.

[0035] The front plate 130 or the rear plate 140 has a length greater than or equal to 300mm, which means that the contact area between the connecting groove 110 and the dust cover 300 is significantly increased. This design enhances the connection strength between the dust cover 300 and the support arm, allowing the dust cover 300 to remain closed more stably during coking and coking processes, effectively preventing it from falling off or shifting due to vibration or impact.

[0036] In one embodiment, the lengths of both the front end plate 130 and the rear end plate 140 are set to 300mm, so that the two sides of the connecting groove 110 have balanced support.

[0037] The longer front plate 130 and rear plate 140 can better distribute the force generated by the dust cover 300 on the support arm, avoiding structural damage caused by stress concentration. At the same time, the longer front plate 130 and rear plate 140 have longer welding lines with the cover plate, thus making the connection more secure.

[0038] In one embodiment, the dry quenching coke installation dust cover support arm also includes a bearing, which is installed in the mounting hole 210.

[0039] As precision mechanical components, bearings achieve an extremely low coefficient of friction through the rolling of their internal rolling elements (such as balls or rollers) between the inner and outer rings. This design significantly reduces the frictional resistance of the dust cover 300 or related moving parts when sliding or rotating on the support arm, resulting in smoother movement and reduced energy loss due to friction.

[0040] In one embodiment, the dry quenching coke loading dust cover support arm also includes a counterweight, which is connected to the second support 200 through a connection hole 220.

[0041] The counterweight is connected to the second support 200 through the connecting hole 220, and its position on the support arm can be adjusted according to actual needs, thereby optimizing the dynamic balance of the support arm. This design enables the support arm to maintain a stable posture when bearing different loads or performing different actions, reducing vibration and swaying caused by imbalance.

[0042] In one embodiment, four connection holes 220 are provided, which are distributed at the four corners of the second support 200, providing four fixing points for the counterweight.

[0043] This multi-point fixing method makes the connection between the counterweight and the second support 200 more stable and the force distribution more even. Compared with a single or a few fixing points, multi-point fixing can effectively reduce the risk of loosening or falling off due to uneven force distribution.

[0044] Through the above embodiments, this application has the following beneficial effects or advantages: The dry quenching coke dust cover support arm disclosed in this application solves the problem of dust cover 300 falling off due to weld stress cracking in existing support arms through the connecting groove 110, effectively ensuring normal production and improving the reliability and stability of dry quenching technology. By increasing the length of the front end plate 130 and the rear end plate 140, a longer connecting groove 110 is formed, increasing the contact area and welding length between the dust cover 300 and the support arm, greatly improving the support strength and reducing the risk of weld stress cracking. The counterweight is set with four connecting holes 220 distributed at the four corners of the second support part 200, allowing the counterweight to distribute the weight more evenly, enhancing the stability of the support arm and reducing the possibility of dust cover 300 falling off. The inclined first support part 100 and second support part 200, as well as the reasonable design of the connecting groove 110 and mounting hole 210, make the support arm structure more reasonable and easier to install and use.

[0045] Based on the same utility model concept, the second aspect of this application discloses a loading device, which includes a loading hopper, a dust cover plate 300 and a dry quenching coke loading dust cover plate support arm of any of the first aspects described above. The dust cover plate 300 is inserted into the connecting groove 110, and the mounting hole 210 is connected to the lug of the loading hopper.

[0046] The insertion device disclosed in this application forms an abutment between the two sides of the dust cover plate 300 through the connecting groove 110, transforming the concentrated stress of traditional spot welding or wire welding into dispersed stress through surface contact, effectively reducing stress concentration in the welding area and lowering the risk of weld cracking. The dust cover plate 300 is welded to the first support part 100 on at least one side, and is mechanically fixed through the connecting groove 110, forming a dual guarantee of welding and mechanical fixation, significantly improving connection strength and impact resistance.

[0047] In one embodiment, both sides of the dust cover 300 are welded to the first support portion 100.

[0048] The dust cover 300 and the first support 100 are connected by welding on both sides, forming a stable overall structure that effectively enhances the overall stability and strength of the installation device.

[0049] In one embodiment, the width of the connecting groove 110 is greater than the thickness of the dust cover 300.

[0050] The design of the groove width being greater than the thickness of the dust cover 300 provides more operating space for the dust cover 300 when inserted into the connecting groove 110, reducing installation difficulty. Operators can more easily align the dust cover 300 with the connecting groove 110 and insert it, improving installation efficiency.
