Description

Technical Field

[0001] The present application relates to the technical field of condensers, and in particular to a vertical condenser applied to a steam turbine oil tank. Background Art

[0002] The vertical condenser in the turbine oil tank usually refers to a condensing device, which is used to condense the steam exhausted from the operation of the turbine into liquid during the cooling process, which helps to recover the heat in the steam and improve the thermal efficiency of the turbine. During the use of the condenser, steam enters its air inlet pipe and is cooled by the internal cooling surface.

[0003] At present, the air inlet pipe of the condenser used in the turbine oil tank is basically installed at a fixed angle. This leads to more stringent requirements on the access angle of the air inlet pipe when the steam enters the air inlet pipe, and it is not flexible enough to use. If the angle of the air inlet pipe is not suitable, the steam may not be able to effectively contact the cooling surface when entering the condenser, affecting the effective cooling and condensation of the steam, thereby reducing the recovered heat. Utility Model Content

[0006] Preferably, the clamp steering mechanism includes a fixing frame fixedly connected to the outer surface of the condenser body, and a top shaft is fixedly penetrated through the top of the fixing frame. There are two groups of top shafts, and the clamp steering mechanism can be used to stabilize the lower clamp and the upper clamp, so that the steering knuckle pipe and the air inlet pipe are stably sealed and connected after steering.

[0007] Preferably, the outer surface of the top shaft is rotatably connected to a main snap ring frame and a secondary snap ring frame, and the main snap ring frame and the secondary snap ring frame are rotatably connected to a group of top shafts respectively.

[0008] Preferably, sealing gaskets are provided on the inner sides of the main snap ring frame and the auxiliary snap ring frame, and a positioning shaft is fixedly penetrated on the inner side of the auxiliary snap ring frame.

[0009] Preferably, the outer surface of the positioning shaft is rotatably connected to a shaft collar, and the outer surface of the shaft collar is fixedly connected to a screw rod.

[0010] Preferably, a butterfly nut is threadedly sleeved on the outer surface of the screw rod, and a recessed groove is provided on the outer surface of the main retaining ring frame, wherein the screw rod can be inserted into the recessed groove, and the screw rod is limited in position in cooperation with the butterfly nut.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The vertical condenser applied to the turbine oil tank can be stably and sealedly connected to the air inlet pipe after adjusting the steering knuckle pipe through the clamp steering mechanism, so that steam from different directions can be accurately connected to the air inlet pipe, which can ensure that the steam is effectively in contact with the cooling surface to improve the condensation efficiency.

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figure 1-4A vertical condenser applied to a turbine oil tank comprises a condenser body 1, an air inlet pipe 2 is arranged on the outer surface of the condenser body 1, a lower clamp 3 is arranged on the top of the air inlet pipe 2, a clamp ring groove 4 is opened on the top of the lower clamp 3, a steering knuckle pipe 5 is movably installed on the top of the air inlet pipe 2 through a clamp steering mechanism, an upper clamp 6 is arranged on the bottom of the steering knuckle pipe 5, and a rubber ring 7 is arranged on the bottom of the upper clamp 6.

[0021] Through the above technical solution, the condenser can rotate the steering knuckle tube 5 during use, and cooperate with the hoop steering mechanism to stably connect it with the air inlet pipe 2, so that steam can enter the air inlet pipe 2 at a suitable angle.

[0022] Specifically, the clamp steering mechanism includes a fixing frame 8 fixedly connected to the outer surface of the condenser body 1, and a top shaft 9 is fixedly penetrated through the top of the fixing frame 8, and the number of the top shafts 9 is two groups.

[0023] Through the above technical solution, the two groups of top shafts 9 are rotatably connected to the main snap ring frame 10 and the auxiliary snap ring frame 11 respectively, that is, the two groups of snap ring frames can be opened and closed.

[0024] Specifically, the outer surface of the top shaft 9 is rotatably connected with a main clamping ring frame 10 and a secondary clamping ring frame 11 respectively.

[0025] Through the above technical solution, the main clamping ring frame 10 and the auxiliary clamping ring frame 11 can stabilize the upper clamping head 6 and the lower clamping head 3 during the closing process.

[0026] Specifically, sealing gaskets 12 are provided on the inner sides of the main snap ring frame 10 and the auxiliary snap ring frame 11 , and a positioning shaft 13 is fixedly penetrated on the inner side of the auxiliary snap ring frame 11 .

[0027] Through the above technical solution, the sealing gasket 12 can maintain good air tightness between the steering knuckle pipe 5 and the air inlet pipe 2 during the connection process.

[0028] Specifically, the outer surface of the positioning shaft 13 is rotatably connected to a shaft collar 14 , and the outer surface of the shaft collar 14 is fixedly connected to a screw rod 15 .

[0029] Through the above technical solution, the position of the screw rod 15 can be adjusted during the process of rotating along the adjustment axis 13 with the shaft ring 14 so as to be clamped into the recessed groove provided on the outer surface of the main clamping ring frame 10 .

[0030] Specifically, a butterfly nut 16 is threadedly sleeved on the outer surface of the screw rod 15 , and a recessed groove is formed on the outer surface of the main snap ring frame 10 .

[0031] Through the above technical solution, after the screw rod 15 is embedded in the recessed groove, the butterfly nut 16 can be screwed to move along the surface of the screw rod 15 until it abuts against the main retaining ring frame 10 to limit the screw rod 15.

[0032] Working principle: When the device is in use, steam enters the condenser body 1 from the air inlet pipe 2 for cooling. In this process, in order to adjust the access angle of the air inlet pipe 2 and improve the flexibility of the device, the angle of the knuckle pipe 5 can be adjusted, so that steam from different directions can be accurately connected to the air inlet pipe 2. That is, after the knuckle pipe 5 is rotated to a suitable angle, the rubber ring 7 at the bottom of the upper clamp 6 is embedded in the clamping ring groove 4 at the top of the lower clamp 3, so that the knuckle pipe 5 maintains good air tightness during the indirect connection with the air inlet pipe 2, and then the main clamping ring frame 10 and the auxiliary clamping ring frame 11 are rotated along the top shaft 9. The two sets of clamping ring frames will clamp the two sets of clamps during the retraction process until the two sets of clamping ring frames tightly clamp the upper and lower sets of clamps, and then the screw rod 15 is moved to make the shaft ring 14 rotate along the adjustment shaft 13 until the screw rod 15 is completely embedded in the outer surface of the main clamping ring frame 10. The butterfly nut 16 can then be screwed along the screw rod 15. When the butterfly nut 16 moves on the surface of the screw rod 15 until it is tightly against the surface of the main clamping ring frame 10, the screw rod 15 is stably limited. At this time, the main clamping ring frame 10 and the auxiliary clamping ring frame 11 are in a state of stably clamping the upper clamping head 6 and the lower clamping head 3. The sealing gasket 12 can improve the connection sealing between the two sets of clamps, so that the steering knuckle pipe 5 after adjusting the direction is stably sealed and connected with the air inlet pipe 2, and the steam is introduced into the condenser body 1 at a suitable angle, which can ensure that the steam is effectively in contact with the cooling surface, thereby improving the condensation efficiency. The access direction of the steering knuckle pipe 5 can be quickly adjusted through the clamp steering mechanism, which can avoid the limitation of the fixed angle, making it easier to maintain and clean, and can reduce the risk of accumulation of dirt and particulate matter in the air inlet pipe 2, reducing the difficulty of system maintenance.
