Description

Technical Field

[0001] The utility model relates to the field of partitions, in particular to a steam turbine dehumidification stage partition. Background Art

[0002] Traditional steam turbine dehumidification baffles are mostly grooved structures on the surface of the nozzle blades. This structure opens a set of radial grooves of a certain length on the pressure surface of the nozzle blades near the steam outlet edge. When the water film flows through the dehumidification groove, it is captured and finally discharged through the baffle drain port.

[0003] However, in order to prevent the steam from overflowing, a sealed containing space is usually provided. When the sealed containing space is full, manual operation is required, which increases the complexity of containing the dehumidification liquid.

[0004] In order to solve the above problems, the present application proposes a steam turbine dehumidification stage partition. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In order to solve the technical problems existing in the background technology, the utility model proposes a steam turbine dehumidification stage partition. The utility model is provided with a containing round box, which is positioned by a positioning piece. As the internal liquid water rises, the floating mechanism is driven to rise to lift the positioning piece and contact the positioning, thereby achieving automatic rotation of the containing round box to replace the storage cavity and increase the convenience of use.

[0007] (II) Technical solution

[0008] In order to solve the above problems, the utility model provides a steam turbine dehumidification stage partition, comprising a dehumidification partition, wherein the dehumidification partition drain port is connected to a sleeve through a connecting pipe;

[0009] The interior of the sleeve is rotatably connected to a round box via a rotating shaft;

[0010] The interior of the containing round box is divided into a containing cavity for containing liquid water discharged from the connecting pipe by a dividing plate;

[0011] The round box is provided with a through opening for communicating with the connecting pipe;

[0012] The sleeve is provided with a positioning piece for positioning the round box;

[0013] A floating mechanism is provided inside the containing round box, and the floating mechanism lifts up the positioning piece when the liquid level rises, so that the containing round box can rotate to replace the containing cavity.

[0014] Preferably, the positioning member includes a positioning pin and a spring, the insertion end of the positioning pin slides into the sleeve and the interior of the round box, one end of the spring is fixedly connected to the positioning pin, and the other end of the spring is fixedly connected to the sleeve.

[0015] Preferably, the T-shaped end of the positioning pin is fixedly connected with a pulling piece.

[0016] Preferably, the floating mechanism includes a float and a push rod, the float is slidably connected to the containing round box via a slider, one end of the push rod is fixedly connected to the float, and the push rod is used to lift the positioning pin.

[0017] Preferably, the push rod is a hollow push rod.

[0018] Preferably, the partition plate is bent in opposite directions on both sides of the middle portion.

[0019] The above technical solution of the utility model has the following beneficial technical effects:

[0020] The liquid water discharged from the dehumidification partition flows into the interior of the sleeve through the connecting pipe. As the liquid water inside the sleeve increases, the liquid level rises to drive the float up, and the float drives the push rod to rise to lift the positioning pin, driving the positioning pin to release the limit on the sleeve. Under the action of gravity, the sleeve rotates to drive the bottom cavity to flip to the upper part and connect with the connecting pipe. The positioning pin is restored by the spring to limit the position of the sleeve, thereby achieving the effect of automatically replacing the containing chamber; the containing chamber rotates to the bottom, and since a through hole is opened, the collected liquid water is automatically discharged, so that the containing chamber can be used again.

[0025] like Figure 1-2 As shown, a steam turbine dehumidification stage partition proposed by the utility model comprises a dehumidification partition 1, and a drain port of the dehumidification partition 1 is connected to a sleeve 3 through a connecting pipe 2;

[0026] The interior of the sleeve 3 is rotatably connected to a round box 4 via a rotating shaft;

[0027] The interior of the holding round box 4 is divided into a holding chamber for holding liquid water discharged from the connecting pipe 2 by a partition plate 6;

[0029] The sleeve 3 is provided with a positioning member 7 for positioning the round box 4;

[0030] A floating mechanism 5 is provided inside the containing round box 4. The floating mechanism 5 lifts up the positioning member 7 when the liquid level rises, so that the containing round box 4 can rotate to change the containing cavity.

[0031] In an optional embodiment, the positioning member 7 includes a positioning pin 71 and a spring 72, the insertion end of the positioning pin 71 slides into the sleeve 3 and the interior of the round box 4, one end of the spring 72 is fixedly connected to the positioning pin 71, and the other end of the spring 72 is fixedly connected to the sleeve 3.

[0032] It should be noted that, under the action of the spring 72 , the positioning pin 71 can move in a self-adaptive manner.

[0033] In an optional embodiment, a pulling member is fixedly connected to the T-shaped end of the positioning pin 71 .

[0034] It should be noted that the pulling member is a pull rope or a pull ring, so as to facilitate pulling the positioning pin 71.

[0035] In an optional embodiment, the floating mechanism 5 includes a float 51 and a push rod 52 . The float 51 is slidably connected to the containing round box 4 via a slider.
