Description

Technical Field

[0001] The utility model relates to the technical field of pipeline thawing, in particular to a device for quickly thawing a frozen pipeline. Background Technique

[0002] The statements in this part are only to provide background information related to the technical solution of the present application to help understanding, and it does not necessarily constitute the prior art for the technical solution of the present application.

[0003] In winter in the northern region, the outdoor temperature is extremely low. During the production processes of the smelting and chemical industries, once problems occur in the outdoor production system, the pipelines are particularly prone to freezing. The general heat preservation methods for metal pipelines are electric tracing or steam tracing, but fiberglass pipelines cannot be heat-preserved. At present, the common treatment method when the pipeline freezes during the production process is to directly insert steam into the pipeline for thawing. However, the steam pressure is too small during thawing, resulting in low thawing efficiency. Especially for long-distance transmission pipelines, it is necessary to cut the pipeline into sections for thawing. Content of the Utility Model

[0004] In view of the problem of low efficiency of the current method of directly thawing with steam, the utility model provides a device for quickly thawing a frozen pipeline, which includes: a flange nipple, which is connected to the flange of the frozen pipeline by bolts; a metal wound gasket provided between the flange nipple and the flange of the frozen pipeline; a steam hose connector welded to the side wall of the flange nipple; a steam hose connected to the steam hose connector, and the steam hose is connected to a steam source; a steam trap connected to the flange nipple by bolts, which can be opened and closed; a steam trap flange connected to the steam trap by bolts; a steam trap connector connected to the steam trap flange; and a steam trap hose connected to the steam trap connector.

[0005] In one embodiment, a metal wound gasket is provided between the flange nipple and the steam trap, and a metal wound gasket is provided between the steam trap and the steam trap flange.

[0006] In one embodiment, a groove is machined on the steam hose connector, and the steam hose connected to the steam hose connector is tied with iron wire outside.

[0007] In one embodiment, a groove is machined on the steam trap connector, and the steam trap hose connected to the steam trap connector is tied with iron wire outside.

[0008] In one embodiment, the steam trap connector is a reducing connector.

[0009] In one embodiment, the steam trap flange is welded to the steam trap connector.

[0010] When the pipeline freezes, the operator connects the flange nipple of the device and the flange of the frozen pipeline with bolts, ties the steam hose and the steam hose connector tightly with wire, ties the drain connector and the drain hose tightly with wire, and puts the other end of the drain hose into the trench for drainage. When thawing, steam is introduced into the steam hose. Due to the function of the steam trap, a certain pressure can be guaranteed in the thawed pipeline. Under high pressure, the thawing efficiency will be significantly improved.

[0011] The metal wound gasket provided between the flange nipple and the flange of the frozen pipeline can guarantee the pressure in the pipeline during thawing. A steam hose connector is welded on the side wall of the flange nipple, and there is a groove on the steam hose connector. When thawing, the rubber hose of the steam and the steam hose connector are tied together with wire to prevent the hose from falling off when the steam pressure is high.

[0012] The other section of the flange nipple is connected to the steam trap by bolts, the other section of the steam trap is connected to the drain flange, a drain connector is welded on the drain flange, there is a groove on the drain connector, and the drain connector and the rubber drain hose are tied together with wire. When thawing, the condensed water generated by the steam flows into the trench through the hose.

[0013] The device for quickly thawing the frozen pipeline provided by the present utility model solves the problem of low thawing efficiency when directly introducing steam during the current production process. By installing a steam trap to provide pressure for the steam in the thawed pipeline, the pipeline can be thawed with steam under high pressure. Through actual application at the production site, the thawing efficiency has been greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS
