Description

Technical Field

[0001] The present application relates to the technical field of hydrophobic expansion tanks, and in particular to a hydrophobic expansion tank. Background Art

[0002] The drain expansion tank is used to expand and reduce the pressure of the drain in the pressure drain pipeline, separate the steam and drain, and introduce the steam into the heat exchanger or deaerator to make full use of its thermal energy, while the drain is introduced into the drain box and regularly sent to the water supply system. It is mainly used to reduce the pressure. If the high-pressure steam directly enters the condenser, it is easy to cause overpressure in the condenser. It can reduce the pressure and avoid overpressure. At the same time, some of them also have a cooling device to reduce the temperature.

[0003] A Chinese patent with publication number CN213146535U discloses a hydrophobic expansion container with convenient water level observation. The rising water level drives the float on the water level display device to move upward, so that the spur rack drives the gear plate inside the fixed box to rotate, and the gear plate drives the hemp rope on the rope reel. The idler wheel and the steering wheel provide sliding force for the hemp rope, so that the slider inside the observation box moves upward. The water level inside the tank can be clearly understood through the scale pointer and the scale mark, so as to avoid excessive overflow of water and save water waste.

[0004] However, water vapor inside the hydrophobic expansion tank will enter the fixed box through the gap between the rack and the fixed box, making the inside of the fixed box humid. Over time, the rack and the gear plate will rust, causing the linkage of the water level display device to be blocked, affecting the understanding of the water level inside the tank. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a hydrophobic expansion tank, which can solve the technical problem that the rack and the gear plate in the existing hydrophobic expansion tank are rusted, causing the linkage of the water level display device to be blocked, affecting the understanding of the water level inside the tank.

[0006] An embodiment of the present application provides a hydrophobic expansion container, comprising a tank body, a support frame is fixedly provided at the bottom of the tank body, a hydrophobic water inlet is provided on one side of the tank body, an exhaust port is provided on the top of the tank body, a hydrophobic drain port is provided on the bottom of the tank body, and a water level display component is provided on one side of the tank body, the water level display component comprises a transparent tube, a scale ruler and a stop bar, the scale ruler and the stop bar are both fixedly provided on the tank body, a placement groove is formed between the scale ruler and the stop bar, the transparent tube is located in the placement groove, one end of the transparent tube is connected to the lower end of the tank body, the other end of the transparent tube is connected to the upper part of the tank body, and both ends of the transparent tube extend into the tank body.

[0007] Furthermore, a transparent protective cover is provided on the outer side of the tank body, and the transparent protective cover covers the water level display assembly.

[0008] Furthermore, a drain valve is installed at the drain outlet.

[0009] Furthermore, a cooling cavity is provided in the tank wall of the tank body, and a cooling water inlet and a cooling water outlet communicated with the cooling cavity are provided on the outer side of the tank body.

The lower end of the tank body 1 is connected, and the other end of the transparent tube 61 is connected to the upper part of the tank body 1. Both ends of the transparent tube 61 extend into the tank body 1. The utility model connects the transparent tube 61 with the tank body 1. The utility model utilizes the principle of the communicating vessel to synchronize the water level in the tank body 1 to the transparent tube 61, and then the water level inside the tank body 1 can be clearly understood through the scale scale 62, wherein the transparent tube 61 is located between the scale scale 62 and the stop bar 63 to form a placement groove, and the transparent tube 61 can be protected by the scale scale 62 and the stop bar 63. Compared with the prior art, the structure is simple, and the problem of linkage obstruction caused by rust on the rack and the gear plate in the prior art is effectively avoided.

[0029] like Figure 2 and Figure 3 As shown, a transparent protective cover 7 is provided on the outside of the tank body 1, and the transparent protective cover 7 covers the water level display assembly 6.

[0031] like Figure 3As shown, a cooling cavity 9 is provided in the tank wall of the tank body 1, and a cooling water inlet 10 and a cooling water outlet 11 which are connected to the cooling cavity 9 are provided on the outer side of the tank body 1. When the drain enters the tank body 1 through the drain inlet 3, cooling water is input into the cooling cavity 9, and heat is exchanged between the cooling water and the drain in the tank body 1, so that the drain is cooled and depressurized, thereby accelerating the separation of water vapor.

[0032] like Figure 3 As shown, a hydrophobic mesh cover 12 is fixedly provided on the inner wall of the tank body 1, and the hydrophobic mesh cover 12 is located at the hydrophobic water inlet 3. When the hydrophobic water enters the tank body 1 from the hydrophobic inlet, the hydrophobic mesh cover 12 is diverted and pressure-released, thereby alleviating the impact of the hydrophobic water on the inside of the tank body 1 and extending the service life of the tank body 1.

[0033] like Figure 1-3 As shown, an inspection port 13 is provided at the top of the tank body 1 , and a matching sealing cover 14 is provided at the inspection port 13 . By opening the sealing cover 14 at the inspection port 13 , the interior of the tank body 1 can be inspected and maintained.
