Description

Technical Field

[0001] The utility model relates to the technical field of steam pipeline drainage, in particular to a steam pipeline emptying device. Background Art

[0002] The essence of steam is water, which is gaseous water containing a lot of heat. During the transportation of steam in the steam pipe, the steam will inevitably lose its latent heat and condense to form condensate. However, condensate does not have the ability to heat objects as quickly as steam, so it must be discharged quickly. Otherwise, the condensate will be blocked in the steam pipe and steam cannot come in, the heat exchange efficiency will be greatly reduced, the product cannot be heated, and the condensate will corrode the heat exchange equipment. Therefore, the condensate needs to be drained away. In the related art, a drain pipe is generally provided at the end of the steam pipe, and a float is provided in the drain pipe. The float automatically controls the switch of the drain pipe, so that the condensate in the drain pipe is automatically drained. However, the bottom of the drain pipe in the prior art is generally provided in the shape of a right-angled step. The float can easily get stuck at the right-angled step, resulting in the drain outlet being unable to be sealed, and steam can easily leak out of the drain outlet. Utility Model Content

The sealing plate 302 matches the drain port of the guide pipe 2. The floating head 301 and the valve stem 303 are respectively connected to the top and bottom of the sealing plate 302. The center of gravity of the valve stem 303 always coincides with the central axis of the guide pipe 2. Under the action of the gravity of the valve stem 303, the sealing plate 302 is highly coincident with the drain port. The bottom of the guide pipe 2 is set to be conical. The inner wall of its bottom is conical, and the sealing plate 302 can move up and down along the inner wall of the guide pipe 2; when steam flows through the first connecting pipe 1, condensed water in the steam will accumulate in the guide pipe 2. When the condensed water reaches a certain amount, under the action of buoyancy, the float head 301 floats up, driving the sealing plate 302 and the valve stem 303 to move upward, thereby opening the drain port and allowing the condensed water to be automatically discharged. The sealing plate 302 will gradually move downward as the condensed water decreases until the sealing plate 302 coincides with the drain port, thereby sealing the drain port; the length of the valve stem 303 extends to the outside of the guide pipe 2. If the drain port is blocked, the valve stem 303 can be pushed to clear it.

[0017] In an optional embodiment, a condensation plate 4 is provided in the first connecting tube 1. The condensation plate 4 is arranged above the guide tube 2. The condensation plate 4 is arranged at an angle to increase the contact area with the steam.

After removing the sealing cover, the filter cartridge 702 can be taken out from the second connecting pipe 701, which is convenient for cleaning or replacing the filter cartridge 702; a valve 10 is installed on the second connecting pipe 701 for controlling the switch of the second connecting pipe 701.

[0019] In an optional embodiment, the number of filter components 7 is at least two groups. If the filter cartridge 702 is replaced, the valve 10 on the corresponding second connecting pipe 701 is first closed, and the other second connecting pipe 701 is connected to ensure that steam can be continuously supplied during the process of replacing the filter cartridge 702.

[0020] The working principle of this embodiment is as follows: when in use, the corresponding second connecting pipe 701 is connected, and the steam flows through the filter cartridge 702, and the steam is filtered by the filter cartridge 702. When flowing through the first connecting pipe 1, under the action of the condensation plate 4, the water droplets in the steam drip along the condensation plate 4 into the guide pipe 2, and the condensed water in the first connecting pipe 1 will also flow into the guide pipe 2. When the condensed water reaches a certain amount, the float head 301 will float up, driving the sealing plate 302 to move upward, thereby opening the drain port of the guide pipe 2, and the condensed water is discharged from the drain port. After the condensed water is drained, under the action of the gravity of the valve stem 303 and the sealing plate 302, the sealing plate 302 quickly seals the drain port. Therefore, the utility model can effectively prevent steam from leaking from the drain port.
