Description

Technical Field

[0001] This utility model belongs to the field of sealing structure technology, and in particular relates to marine condensate seal devices. Background Technology

[0002] With the development of shipping, the requirements for ship emissions are becoming increasingly stringent. In particular, the issue of condensate discharge caused by negative pressure differentials in ship refrigeration equipment is receiving more and more attention. When a negative pressure differential is generated inside the refrigeration equipment, it can draw normally discharged condensate back into the refrigeration equipment, causing damage to the equipment and affecting the normal refrigeration operation of the ship. In addition, when the ship is in operation, external air or impurities can enter the refrigeration equipment, affecting its use.

[0003] Therefore, there is a need for a marine condensate seal device that can not only allow condensate to be discharged normally, but also prevent condensate from being drawn back into the refrigeration equipment due to negative pressure differential during operation, and prevent external air or impurities from entering the refrigeration equipment. Utility Model Content

[0004] The main purpose of this utility model is to provide a marine condensate seal device to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A marine condensate seal device includes a water seal tank. One end of the water seal tank is connected to a water inlet via a first water pipe, and the other end of the water seal tank is connected to a drain outlet opposite to the water inlet via a second water pipe. The height of the second water pipe from the bottom of the water seal tank is lower than the height of the first water pipe from the bottom of the water seal tank. A baffle is vertically installed inside the water seal tank, fitting against the side wall and top wall of the water seal tank. The bottom of the baffle is spaced from the bottom of the water seal tank. An end plate is installed between the baffle and the side wall of the water seal tank, parallel to the bottom of the water seal tank. A water outlet is provided at the center of the end plate. A suspended ball that can seal with the water outlet is placed on the upper surface of the end plate.

[0007] As a preferred embodiment of the marine condensate seal device of this utility model, the diameter of the water outlet is smaller than the diameter of the suspended ball.

[0008] As a preferred embodiment of the marine condensate seal device of this utility model, a condensate drain port is provided at the bottom of the other side of the water seal tank, and the condensate drain port is located between the end plate and the bottom of the water seal tank.

[0009] As a preferred embodiment of the marine condensate seal device of this utility model, the height of the end plate from the bottom of the water seal tank is less than the height of the second water pipe from the bottom of the water seal tank.

[0010] As a preferred embodiment of the marine condensate seal device described in this utility model, the top of the water seal tank is equipped with an inspection door for easy access to the suspended ball, and one end of the inspection door is fixedly connected to a hinge.

[0011] Compared with the prior art, the present invention will have at least the following beneficial effects:

[0012] When the condensate is between the first and second liquid levels in the water trap, it provides a seal, effectively preventing external air or impurities from entering the refrigeration equipment through the water seal tank and avoiding damage. When the refrigeration equipment generates negative pressure and the drain outlet is under positive pressure, the suspended ball will be adsorbed onto the end plate under the negative pressure difference, sealing it with the water outlet on the end plate. This blocks the flow of condensate within the water seal tank, preventing backflow into the refrigeration equipment and avoiding damage. The access door facilitates the replacement of the suspended ball and maintains the sealing effect between the suspended ball and the water outlet. Attached Figure Description

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0020] like Figures 1-2 As shown, a marine condensate seal device includes a water seal tank 1. One end of the water seal tank 1 is connected to an inlet 3 via a first water pipe 2. Normally, the inlet 3 is connected to the outlet of a refrigeration unit inside the ship. Condensate generated by the refrigeration unit enters the water seal tank 1 through the inlet 3 and the first water pipe 2. The other end of the water seal tank 1 is connected to a drain outlet 5 opposite to the inlet 3 via a second water pipe 4. Condensate is discharged through the second water pipe 4 into the drain outlet 5. The height of the second water pipe 4 from the bottom of the water seal tank 1 is lower than the height of the first water pipe 2 from the bottom of the water seal tank 1. A vertically mounted device is installed inside the water seal tank 1. A baffle 6 is fitted to the side wall and top wall. The bottom of the baffle 6 is spaced from the bottom of the water seal tank 1. An end plate 7 is installed between the baffle 6 and the side wall of the water seal tank 1, parallel to the bottom of the water seal tank 1. A water outlet 8 is provided at the center of the end plate 7. A suspended ball 9 that can seal with the water outlet 8 is placed on the upper surface of the end plate 7. Generally, the suspended ball 9 is hollow. To ensure that the suspended ball 9 can seal with the water outlet 8, the diameter of the water outlet 8 should be smaller than the diameter of the suspended ball 9. The internal space of the water seal tank 1 and the baffle 6 and end plate 7 installed in the water seal tank 1 form a water trap with a certain depth.

[0021] like Figure 3 As shown in this embodiment, when the condensate discharged from the refrigeration equipment enters the water trap in the water seal tank 1, and the liquid level in the water trap is between the first liquid level and the second liquid level, according to common sense physics, the condensate at this time has a sealing effect, which can effectively prevent external air or impurities from entering the refrigeration equipment through the water seal tank 1, and avoid damage to the refrigeration equipment.

[0022] In this embodiment, when the refrigeration equipment generates negative pressure and the drain outlet 5 is under positive pressure, the suspended ball 9 will be adsorbed onto the end plate 7 under the action of the negative pressure difference, so that it seals with the water outlet 8 on the end plate 7. The flow of condensate in the water seal tank 1 is blocked, thus preventing condensate from being sucked back into the refrigeration equipment and avoiding damage to the refrigeration equipment.

[0023] In this embodiment, when the refrigeration equipment does not generate negative pressure, that is, in the normal state, when the condensate reaches or is above the first liquid level, the suspended ball 9 will detach from the water outlet 8 and float up under the action of buoyancy. The condensate flows along the water outlet 8 through the second water pipe 4 to the drain outlet 5 and is discharged.

[0024] Furthermore, a condensate drain port 10 is provided at the bottom of the other side of the water seal tank 1. The condensate drain port 10 is located between the end plate 7 and the bottom of the water seal tank 1. Under normal circumstances, the condensate cannot be completely drained. When the liquid level of the condensate in the water trap is below the second liquid level, the condensate drain port 10 is opened to allow the remaining condensate to be discharged from the condensate drain port 10. Even if the condensate at the bottom of the condensate drain port 10 cannot be completely drained, the remaining condensate will not be drawn back into the refrigeration equipment.

[0025] Furthermore, the height of the end plate 7 from the bottom of the water seal tank 1 is less than the height of the second water pipe 4 from the bottom of the water seal tank 1. This design is to prevent the liquid level in the water trap from exceeding the height of the second water pipe 4, thus preventing condensate from being unable to drain from the second water pipe 4. If the height of the end plate 7 from the bottom of the water seal tank 1 is greater than the height of the second water pipe 4 from the bottom of the water seal tank 1, there is a risk of condensate being drawn back into the refrigeration equipment.

[0026] Furthermore, if the suspended ball 9 is used for a long time without being replaced, impurities will be absorbed on its outer periphery, which will reduce the sealing effect between it and the water outlet 8 and affect the normal use of the water seal device. Therefore, an inspection door 11 is installed on the top of the water seal tank 1 to facilitate the removal of the suspended ball 9. To facilitate the opening and closing of the inspection door 11, the inspection door 11 is matched with the hinge 12 so that one end of the inspection door 11 is fixedly connected to the hinge 12.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
