Description

Technical Field

[0001] This utility model relates to the technical field of oil injection devices for gas seal tiles, and in particular to a hose assembly for oil injection of gas seal tiles in gas blowers. Background Technology

[0002] Gas blowers are core equipment in the coking industry. Their high- and low-pressure end gas seals prevent gas from leaking axially from the high-pressure end and air from being drawn in from the low-pressure end during high-speed rotation. To ensure the sealing performance of the gas seals, grease needs to be added periodically. Traditionally, adding grease to gas seals requires manual tightening of the grease cup by the operator. Specifically, after filling the cup, it needs to be aligned with the threaded hole (oil injection port) on the gas blower and tightened to force the grease into the gas seal. However, in practice, the oil injection port is too close to the blower's rotating shaft, making operation inconvenient and posing a safety hazard. Therefore, this application proposes a hose assembly for grouting gas seals in gas blowers. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a hose assembly for oil injection of gas blower gas seal tile. The technical solution to the problem is that it includes a blower body, on which an oil injection hole is opened to cooperate with the gas seal tile inside. The oil injection hole is threadedly connected to the outlet end of a pipe joint, the pipe joint is integrally and coaxially provided with a hexagonal nut, and the inlet end of the pipe joint is fixedly connected to the hose assembly. The hose assembly includes an outlet end of a hose that is fixedly connected to the inlet end of a hose connector. The inlet end of the hose is fixedly connected to the outlet end of a gun connector. The hose connector has a slot coaxially formed. An adjusting sleeve is rotatably connected to the slot. A mounting plate is fixedly connected to the outer edge of the adjusting sleeve. An L-shaped fork is fixedly connected to the mounting plate. A crossbar is fixedly connected to the L-shaped fork. A support sleeve coaxially fitted with the hose is fixedly connected to the crossbar. A limiting component that cooperates with the adjusting sleeve is provided on the hose connector.

[0004] Preferably, the limiting component includes a limiting screw hole at the left end of the pipe joint corresponding to the end face of the adjusting sleeve, and the limiting screw hole is threadedly connected to a set screw that abuts against the adjusting sleeve.

[0005] The beneficial effects of this utility model are: In use, the hose assembly extends the distance of the oil filling hole through the hose, and the inlet end of the hose is provided with a gun connector that connects to the grease gun. Thus, grease can be added into the oil filling hole by using the grease gun in conjunction with the hose assembly, which solves the problem of inconvenience and operational risks in adding grease to the oil cup due to the close distance between the oil filling hole and the fan rotating shaft.

[0012] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be described in further detail.

[0013] In the first embodiment, the technical solution is as follows: During use, the blower body 1 has an oil injection hole 2 for the air seal tile. The hose assembly 5 extends the distance of the oil injection hole 2 via a hose 6, and the inlet end of the hose 6 is equipped with a gun connector 7 for connecting with a grease gun. This allows grease to be added to the oil injection hole 2 using a grease gun in conjunction with the hose assembly 5, solving the problem of inconvenience and operational risks associated with adding grease to the oil cup due to the close proximity of the oil injection hole 2 to the blower's rotating shaft. To facilitate the connection and disassembly of the pipe connector 3 and the oil injection hole 2, a hexagonal nut 4 is provided on the pipe connector 3, allowing for installation and disassembly of the pipe connector 3 and the oil injection hole 2 using a wrench and the hexagonal nut 4. The gun connector 7 can be any existing suitable model that can connect with a grease gun; it will not be described in detail here.

[0014] In Example 2, based on Example 1, specifically, in use, the outlet end of the pipe connector 3 can be screwed into the oil filling hole 2 via a threaded connection, and then grease can be added through the hose assembly 5. To prevent the L-shaped fork 11 and other related components from affecting the screwing of the pipe connector 3 into the oil filling hole 2, it is necessary to first release the restriction of the limiting component 14 on the adjusting sleeve 9, that is, unscrew the set screw 16. Then, the pipe connector 3 can be rotated independently without the L-shaped fork 11 and the adjusting sleeve 9 moving, so that the pipe connector 3 can be screwed into the oil filling hole 2 smoothly. After tightening the pipe connector 3, adjust the position of the L-shaped fork 11. Specifically, rotate the L-shaped fork 11. Since the fork is fixedly connected to the adjusting sleeve 9 in the slot 8 through the mounting plate 10, the L-shaped fork 11 can rotate around the slot 8 with the adjusting sleeve 9. Rotate the L-shaped fork 11 to make it as shown in the attached drawings. Figure 1-2 As shown, the L-shaped fork 11 is perpendicular to the horizontal plane at this time, so that the support sleeve 13, which is fixedly connected to the L-shaped fork 11 via the crossbar 12, is located on the upper side. This allows the inlet end of the hose 6, secured by the support sleeve 13, to be positioned above the outlet end, ensuring smooth grease flow. After adjusting the position of the L-shaped fork 11, screw the set screw 16 of the limiting assembly 14 into the limiting screw hole 15 and tighten it against the adjusting sleeve 9. This restricts the movement of the fork.
