Description

Technical Field

[0001] This utility model relates to the field of air volume balancing technology for exhaust systems, and in particular to an air volume balancing filter device for use in the exhaust system of a ship's dryer. Background Technology

[0002] The dryers in the ship's laundry room will continuously emit exhaust gas during operation. This exhaust gas should be discharged directly to the outside in a timely and smooth manner. Usually, the exhaust gas emission system of the dryers is combined with the indoor ventilation system of the laundry room. Therefore, when calculating the air volume of the indoor ventilation system fan, it will be considered based on the maximum operating condition. For example, if all the dryers in the room are running at the same time, the air volume will be the largest. The design of each pipeline of the entire ventilation system will also be based on this operating condition.

[0003] In actual ship applications, it was found that sometimes only some of the dryers in the laundry room were running, instead of all of them running at the same time. When the dryers were not running, no exhaust gas was discharged, which would lead to an imbalance in the air volume of the exhaust fan, thereby disrupting the balance of the entire exhaust system and the overall air volume balance in the room. This could create positive pressure in the room, causing indoor gas to overflow into the surrounding cabin environment, and there is also a risk of odor overflow. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, and to avoid the adverse effects caused by the imbalance of air volume in the exhaust system of the laundry room, this utility model provides an air volume balancing filter device for the exhaust system of a ship dryer, so as to eliminate the problem of air volume imbalance.

[0005] This utility model embodiment provides an airflow balancing filter device for the exhaust system of a ship's dryer, comprising:

[0006] A balancing filter is installed in the laundry room. One end is connected to the exhaust pipe, and the other end is connected to the exhaust port of the dryer through a flexible hose. The balancing filter has an opening for connection with the laundry room to balance the air volume.

[0007] The size of the opening is determined based on the cross-sectional area of ​​the hose;

[0008] When the dryer is working, the dryer discharges exhaust gas through a hose via an internal mechanical exhaust fan, and after passing through the balance filter, it is discharged through the exhaust pipe.

[0009] When the dryer is not in operation, the exhaust pipe is connected to the laundry room through the opening on the balance filter to maintain the air volume balance of the exhaust system.

[0010] In some embodiments of this utility model, multiple dryers installed in the laundry room are connected to corresponding exhaust pipes through corresponding flexible hoses and balance filters, and multiple exhaust pipes converge into a main exhaust pipe, on which an exhaust fan is installed;

[0011] When the dryer is working, the exhaust fan is used to exhaust the waste gas emitted by the dryer;

[0012] When the dryer is not in operation, the exhaust pipe is connected to the laundry room through the opening on the balance filter to maintain the air volume balance of the exhaust system.

[0013] In some embodiments of this utility model, the balancing filter is arranged in a rectangular box structure, with one side of the balancing filter attached to the wall panel of the laundry room, and a connection hole for communicating with a hose opened on the other side.

[0014] The opening is made on the side where the balance filter connects to the hose.

[0015] In some embodiments of this utility model, the balance filter is provided with a filter screen for filtering the gas entering the exhaust pipe.

[0016] In some embodiments of this utility model, the filter screen is specifically a pull-out mesh filter screen.

[0017] In some embodiments of this utility model, the opening area is 80%-150% of the cross-sectional area of ​​the hose.

[0018] In some embodiments of this utility model, the dryer is equipped with an air inlet grille. During drying, the mechanical exhaust fan draws in air through the grille and discharges it through a hose.

[0019] Compared with existing technologies, the beneficial effects of the airflow balancing filter device for the exhaust system of a ship's dryer provided in this embodiment are as follows: By connecting one end of the dryer's exhaust port to the airflow balancing filter via a flexible hose, and directly connecting the other end of the balancing filter to the indoor exhaust system, the balancing filter is installed on the indoor wall, and the balancing opening on the filter is exposed to the laundry room, thus eliminating the problem of airflow imbalance. Considering that the exhaust gas emitted by the dryer contains fine lint and other impurities, a removable mesh filter is added to the balancing filter to filter these impurities, and the filter can be periodically removed for cleaning.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Various embodiments and features of this application are described herein with reference to the accompanying drawings.

[0027] These and other features of this application will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.

[0028] It should also be understood that although this application has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this application, which have the features described in the claims and are therefore all within the scope of protection defined herein.

[0029] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0030] Specific embodiments of this application are described below with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to ascertain the true intent based on the user's historical operations, and to avoid unnecessary or redundant details that would obscure this application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in various ways with substantially any suitable detailed structure.

[0031] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0032] This utility model provides an airflow balancing filter device for the exhaust system of a ship's dryer, such as... Figure 2 and Figure 3 As shown, it includes:

[0033] The balancing filter 1 is installed in the laundry room. One end is connected to the exhaust pipe 2, and the other end is connected to the exhaust port of the dryer 4 through the hose 3. The balancing filter 1 has an opening 5 that is connected to the laundry room for airflow balancing.

[0034] The size of the opening 5 is determined based on the cross-sectional area of ​​the hose 3; specifically, the area of ​​the opening 5 is 80%-150% of the cross-sectional area of ​​the hose 3.

[0035] When the dryer 4 is working, the dryer 4 discharges the exhaust gas through the hose 3 via the internal mechanical exhaust fan, and after passing through the balance filter 1, it is discharged through the exhaust pipe 2.

[0036] When the dryer 4 is not working, the exhaust pipe 2 is connected to the laundry room through the opening 5 on the balance filter 1 to maintain the air volume balance of the exhaust system.

[0037] Specifically, by Figure 1 and Figure 2 The comparison shows that, before the modification, in the existing 4-exhaust system of the ship's dryer, specifically as follows: Figure 1 As shown, when the dryer 4 is working, air enters through the bottom grille (point A) of the dryer 4. After the clothes are heated and dried inside the dryer 4, the exhaust gas is discharged through the hose 3 and finally discharged to the outside by the exhaust system in the laundry room. However, if the dryer 4 stops working, there is no exhaust gas discharged, which directly leads to a reduction in the exhaust volume and causes an imbalance.

[0038] After modification, specifically in the marine dryer exhaust system provided in the above embodiments of this application, please refer to [the relevant documentation]. Figure 2 and Figure 3 As shown, an airflow balancing filter 1 is added to the pipeline. When the dryer 4 is working, as before the modification, air enters through the bottom grille (point A) of the dryer 4. At this time, the balancing opening 5 (point B) on the balancing filter 1 does not draw in air. The system still exhausts the exhaust gas from the dryer 4 because the dryer 4 contains a mechanical exhaust fan that provides power for exhaust gas discharge. At this time, the air drawn out by the balancing filter 1 is the exhaust gas from the hose 3, not from the balancing opening 5 (point B). When the dryer 4 is not working, point A no longer receives air, and the balancing filter 1 will preferentially draw out the air from the balancing opening 5 (point B). This keeps the airflow of the exhaust system constant and maintains the original balance. Since the air drawn in by the balancing opening 5 also comes from inside the laundry room, it does not affect the airflow balance in the laundry room. This perfectly solves the airflow imbalance problem caused by the dryer 4 not working.

[0039] In some embodiments of this utility model, multiple dryers 4 that can be installed in the laundry room are respectively connected to the corresponding exhaust pipes 2 through the corresponding hoses 3 and balance filters 1, and the multiple exhaust pipes 2 converge into the exhaust main pipe, on which an exhaust fan is installed.

[0040] When the dryer 4 is working, the exhaust fan is used to exhaust the exhaust gas from the dryer 4;

[0041] When the dryer 4 is not working, the exhaust pipe 2 is connected to the laundry room through the opening 5 on the balance filter 1 to maintain the air volume balance of the exhaust system.

[0042] In some embodiments of this utility model, the balance filter 1 is arranged in a rectangular box structure, one side of the balance filter 1 is attached to the wall panel of the laundry room, and the other side has a connection hole that communicates with the hose 3.

[0043] The opening 5 is made on the side where the balance filter 1 is connected to the hose 3.

[0044] Furthermore, considering that the exhaust gas emitted by the dryer 4 contains fine lint and other impurities, the balance filter 1 is equipped with a filter screen 6 to filter the gas entering the exhaust pipe 2, thereby filtering out impurities. As an example, the filter screen 6 is specifically a pull-out mesh filter screen, which allows the filter to be periodically removed for cleaning.

[0045] As can be seen from the above technical solution, the airflow balancing filter 1 device for the exhaust system of the ship's dryer 4 provided in the above embodiment of this utility model connects one end of the airflow balancing filter 1 to the exhaust port of the dryer 4 through a hose 3, and the other end of the balancing filter 1 is directly connected to the indoor exhaust system. The balancing filter 1 is installed on the indoor wall, and the balancing opening 5 on the balancing filter 1 is exposed to the laundry room. Considering that there are fine impurities such as lint in the exhaust gas emitted by the dryer 4, a removable mesh filter is added to the balancing filter 1 to filter these impurities, and the filter can be periodically removed for cleaning.

[0046] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
