Technical Field

[0001] The utility model belongs to the technical field of condensate recovery devices, and particularly relates to a condensate recovery device for a turbine. Background Technique

[0002] A turbine is a common mechanical device widely used in the fields of aviation, aerospace, energy, chemical industry, etc. Its working principle is to convert the kinetic energy of a fluid into mechanical energy through the interaction between the turbine wheel blades and the working fluid. The condensate generated in the turbine is recovered and processed by a condensate recovery device. The condensate is high-quality water and contains a large amount of heat energy. Therefore, recovering condensate in a steam heating system is one of the important measures for energy conservation and water conservation.

[0003] The existing condensate recovery device for a turbine is used to recover and process the condensate generated by the turbine. An overflow pipe is installed on the recovery device to facilitate the timely overflow of excessive liquid in the device. However, there are the following defects: (1) During the use of the existing condensate recovery device for a turbine, since the port of the overflow pipe is in an open form, external impurities and organisms are likely to enter the device through the overflow pipe, which is likely to cause damage to the inside of the device and blockage, affecting the later overflow and drainage effects. For this reason, we propose a condensate recovery device for a turbine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a condensate recovery device for a turbine to solve the problem that impurities and organisms are likely to enter the overflow pipe of the condensate recovery device for a turbine, resulting in damage to the device and inability to be used normally as described in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A condensate recovery device for a turbine, including a condensate recovery body, an overflow pipe is arranged on the condensate recovery body, a plug cylinder is sleeved on the top end of the overflow pipe, overflow holes are opened on the side wall of the plug cylinder, a floating plate is connected inside the plug cylinder in a sliding manner, a retaining ring is arranged at the bottom of the floating plate, and the retaining ring is fixed on the inner wall of the plug cylinder.

[0006] Preferably, a guide cylinder is fixedly embedded at the top end of the plug cylinder, a guide rod is connected inside the guide cylinder in a sliding manner, and one end of the guide rod is fixed on the surface of the floating plate.

[0007] Preferably, the cross-sections of both the guide rod and the guide cylinder are circular structures, and the central axes of both the guide rod and the guide cylinder coincide with each other.

[0008] Preferably, a spring is arranged at the top of the guide rod, and the spring is inside the guide cylinder.

[0009] Preferably, a rib plate is jointly connected to the surface of the guide rod and the floating plate, and the longitudinal section of the rib plate is a triangular structure.

[0010] Preferably, there are two rib plates, and the two rib plates are symmetrical about the central axis of the guide rod.

[0011] Preferably, the cross section of the floating plate is a circular structure, and a rubber ring is sleeved on the outer wall of the floating plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] (1) Through the designed plug cylinder, overflow hole, floating plate and retaining ring, the plug cylinder equipped with the floating plate is sleeved at the nozzle of the overflow pipe of the present utility model. When overflowing, the water exerts a buoyancy force on the floating plate, causing the floating plate to float, and finally the water is discharged from the overflow hole. When the present utility model does not perform overflow treatment, the floating plate falls on the retaining ring to block the port of the overflow pipe, preventing external impurities and organisms from entering the interior of the recovery device through the nozzle and causing damage, which affects the normal overflow discharge in the later stage. Through the designed guide cylinder and guide rod, the movement of the floating plate is supported and guided to prevent the floating plate from tilting. Through the designed spring, an elastic pressing force is applied to the guide rod to push the floating plate to move downward and reset without the buoyancy force, preventing it from not being able to reset and block in time under its own gravity. Through the designed rubber ring, the rubber ring has good flexible deformation ability to seal the gap between the side of the floating plate and the inner wall of the plug cylinder.

When overflowing, the water generates buoyancy on the floating plate 9, so that the floating plate 9 floats up , and finally the water is discharged from the overflow hole 5. When the utility model is not overflowing, the floating plate 9 falls on the retaining ring 10 to seal the port of the overflow pipe 2 to prevent external impurities and organisms from entering the recovery device through the pipe orifice and causing damage, affecting the normal overflow discharge in the later stage. The retaining ring 10 is fixed on the inner wall of the plugging cylinder 6. The top of the plugging cylinder 6 is fixed with a guide cylinder 3 by inlaying. The inside of the guide cylinder 3 is connected with a guide rod 7 by sliding. Through the designed guide cylinder 3 and guide rod 7, the floating plate 9 is supported and guided to avoid the floating plate 9 from being skewed.
