Description

Technical Field

[0001] This utility model belongs to the field of clamping technology, and in particular relates to a safe and efficient oxygen molten rod clamping device. Background Technology

[0002] Oxygen smelting rods are tools that generate high temperatures for rapid melting, cutting, and cleaning under the aid of oxygen combustion. In the metallurgical industry, workers hold oxygen smelting rods and blow in oxygen for melting, cutting, or guiding flow, which is a common high-temperature operation technique. The principle is to inject high-pressure oxygen into the molten metal or high-temperature area to accelerate the oxidation reaction, improve smelting efficiency, or clear the metal flow channels.

[0003] However, the connection method between the oxygen fusion rod and the oxygen source is usually to directly insert the oxygen fusion rod into the pressure-resistant hose and tighten it with iron wire or metal cable ties, or to insert the oxygen fusion rod into a metal sleeve connected to the pressure-resistant hose, drill and tap the front end of the metal sleeve, and screw in bolts to tighten the oxygen fusion rod. This poses serious safety hazards. The connection point has poor airtightness, which can easily lead to oxygen leakage, resulting in deflagration and burns. High-temperature molten metal can flow back into the oxygen fusion rod, burn through the pipeline, and cause an explosion. There are also technical problems such as the inability to firmly fix the oxygen fusion rod, easy detachment, and long time and low efficiency in replacing the oxygen fusion rod.

[0012] Furthermore, a metal particle sintered mesh is provided at the bottom of the interior of the outer shell, and a second hole retaining ring is provided above the metal particle sintered mesh at the bottom of the inner side wall of the outer shell.

[0013] Furthermore, a gasket is provided between the top of the fluororubber sealing sleeve inside the housing and the bottom of the conical locking spring, and the gasket is annular.

[0015] This utility model has the following beneficial effects:

[0016] This invention ensures the airtightness of the oxygen torch connection after compression and tightening by setting a fluororubber sealing sleeve, maintaining a pressure of 5 bar, thus eliminating the safety hazards of deflagration and burns caused by oxygen leakage. Furthermore, the use of a sintered metal particle mesh effectively prevents the backflow of high-temperature molten metal into the oxygen torch and burns through the pipeline while ensuring unobstructed oxygen flow.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figures 1-4 As shown, this utility model is a safe and efficient oxy-fuel rod clamping device, including a housing 1, a locking cap 2 disposed on one side of the outer side of the housing 1, and a snap ring fixing seat 7 disposed at the top of the inner side of the housing 1, and further including:

[0026] A conical sleeve 8 is located inside the locking cap 2, and a connecting bearing 9 is provided between the top of the outer side of the conical sleeve 8 and the top of the inner side of the locking cap 2; a conical locking spring 6 is located inside the spring retainer 7; a sealing sleeve base 4 is located inside the outer shell 1 near the middle, and a fluororubber sealing sleeve 5 is provided inside the sealing sleeve base 4. An annular gasket 11 is provided between the top of the fluororubber sealing sleeve 5 inside the outer shell 1 and the bottom of the conical locking spring 6. The top of the inner side of the outer shell 1 is provided with an internal thread, and the outer side of the outer shell 1... The top of the locking cap 2 is provided with an external thread, and the bottom of the inner side of the locking cap 2 is provided with an internal thread that mates with the top thread on the outer side of the outer shell 1. The outer side of the tapered sleeve 8 near the top is provided with an external thread that mates with the top thread on the inner side of the outer shell 1. A retaining ring 10 for the first hole is engaged between the middle position of the outer side of the tapered sleeve 8 and the inner side wall of the locking cap 2. After the locking cap 2 and the tapered sleeve 8 are connected by the connecting bearing 9, the retaining ring 10 for the first hole is engaged into the groove provided on the outer side of the tapered sleeve 8 and the inner side of the locking cap 2, thereby securing the tapered sleeve 8. The connecting bearing 9 is fixed inside the locking cap 2. A metal particle sintered mesh 3 is provided at the bottom of the inside of the outer shell 1. A second hole retaining ring 12 is provided above the metal particle sintered mesh 3 at the bottom of the inner side wall of the outer shell 1. When the metal particle sintered mesh 3 is placed into the bottom of the inside of the outer shell 1, the second hole retaining ring 12 is engaged in the slot provided above the metal particle sintered mesh 3 at the bottom of the inner side of the outer shell 1 to fix the metal particle sintered mesh 3. Then, the locking cap 2 is manually screwed onto the top of the outer side of the outer shell 1. The inner side wall of the cone sleeve 8 The bottom end is chamfered, and the bottom end of the inner side wall of the cone sleeve 8 fits against the top of the outer side of the cone locking spring 6. After inserting the oxygen fusion rod into the clamping connection device, manually rotate the locking cap 2 to make the cone sleeve 8 press the cone locking spring 6 to clamp and fix the oxygen fusion rod. At the same time, the cone locking spring 6 compresses the fluororubber sealing sleeve 5 to ensure the airtightness of the oxygen fusion rod connection. When performing melting, cutting or diversion processing, the metal particle sintering mesh 3 effectively prevents the high temperature melt from flowing back into the oxygen fusion rod and burning through the pipe while ensuring the smooth flow of oxygen.

[0027] In use, first place the sintered metal particle mesh 3 into the bottom of the inner shell 1 and fix it with the retaining ring 12 through the second hole. Then, install the sealing sleeve base 4, fluororubber sealing sleeve 5, gasket 11 and conical locking spring 6 in sequence. Finally, screw in the spring fixing seat 7 to fix it. Then, manually screw the locking cap 2, which is fixed inside the conical sleeve 8 and the connecting bearing 9 through the first hole with the retaining ring 10, onto the outer top of the outer shell 1 through the threaded connection. The clamping device can then be assembled. Then, insert the oxygen fusion rod into the inside of the device, manually rotate the locking cap 2, and drive the conical sleeve 8 to press the conical locking spring 6 into the inner side of the outer shell 1 so that its top end contracts and clamps and fixes the oxygen fusion rod. At the same time, the conical locking spring 6 compresses the fluororubber sealing sleeve 5 to make it tighten, ensuring the airtightness of the oxygen fusion rod inserted and fixed in the device.

[0028] Working principle: When using the oxygen fusion rod clamping device, the oxygen fusion rod is inserted into the locking cap 2 and passes through the conical locking spring 6 and the fluororubber sealing sleeve 5. Then, the operator manually rotates the locking cap 2, causing the conical sleeve 8 to move inward toward the outer shell 1 and press against the conical locking spring 6, causing its top to contract inward, thereby clamping and fixing the oxygen fusion rod in the device. At the same time, the conical locking spring 6 compresses and tightens the fluororubber sealing sleeve 5, so that the inner side of the fluororubber sealing sleeve 5 is tightly fitted with the outer side of the oxygen fusion rod that passes through it, ensuring the airtightness of the oxygen fusion rod inserted in the device. When the oxygen fusion rod generates high temperature through oxygen combustion for rapid melting and cleaning operations, the metal particle sintered mesh 3 can prevent the high temperature melt from flowing back into the oxygen fusion rod and burning through the pipe while ensuring the smooth flow of oxygen.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
