Description

TECHNICAL FIELD

[0001] The present application relates to an air purification device, in particular to an air purification device for a ship. BACKGROUND

[0002] The ship is an important means of transportation for sea battle or operation. Due to the complex sea environment, and the operation of the machine equipment in the cabin of the ship itself can also produce some suspended particulate pollutants such as PM2.5, dust and other particulate matter, or volatile organic compounds such as benzene, toluene, xylene, trichloroethylene or trichloroethane, and the space of the cabin of the ship is relatively airtight. When the concentration of these harmful gases exceeds a certain concentration, it will cause human poisoning.

[0003] In order to solve the above technical problems, it is necessary to install an air purification device on the ship. However, the filter element for achieving the filtering effect in the existing air purification device is generally a whole structure, so as to achieve the purpose of convenient replacement, that is, when replacing, the whole filter element can be directly replaced. However, the specific components of the whole filter element are generally a combination of multiple layers of filter screens stacked and fixed to achieve different functional effects. For example, the primary filter screen near the air inlet is used to filter large particles of dust and flying particles, and other filter screens in the direction of the air outlet are used to filter small particles of dust or viruses. Since the first layer of filter screen near the air inlet is closest to the pollution source, its service life will be the shortest. Once it is blocked, it will directly affect the use effect of the whole filter element. Therefore, when the whole filter element is directly replaced, material costs will be wasted. In addition, for some large ships, the time of a single voyage may be relatively long. Therefore, it is inevitable to face the problem that it is difficult to obtain supplies in time if the filter element is short during the sea voyage.

[0004] In order to solve the above technical problems, although the air purification device can be manually disassembled in extreme cases, and the individual filter screen of the filter element can be removed, since the filter screen is mixed with a large amount of pollutants, manual disassembly is not only dangerous, but also time-consuming and laborious. In addition, the use of the air purification device needs to be closed during maintenance, so the convenience is poor. SUMMARY

[0005] In order to solve the above technical problems, the purpose of the present application is to provide an air purification device for a ship, which can not only remove or replace the individual filter screen layer during the operation of the device, but also has convenient maintenance, higher automation, and better safety of manual operation.

[0006] The present application provides the following technical solutions:

[0007] The application discloses a ship air purification device, which comprises a purification installation shell with an air inlet and an air outlet, and a set of blocking plates in the purification installation shell, wherein an axial flow fan is installed at the air outlet, the blocking plates are used for separating the space in the purification installation shell into a left chamber and a right chamber, and at least two pairs of sliding plate groups are installed on the blocking plates in parallel along the airflow direction, two groups of sliding unit plates in each pair of sliding plate groups are synchronously slid into the left chamber or the right chamber under the drive of corresponding driving members, and abut and seal the inner walls of the corresponding left chamber or right chamber to block the airflow, airflow redirection channels are formed in the blocking plates between the two adjacent pairs of sliding plate groups and between the blocking plates between the most edge sliding plate groups and the air inlet and the air outlet, and a set of filter screen groups are arranged in the corresponding left chamber and right chamber between each pair of sliding plate groups, when the two groups of sliding unit plates in a pair of sliding plate groups are synchronously slid into the left chamber or the right chamber, the two groups of sliding unit plates abut and seal the inner walls of the left chamber or the right chamber, so as to form a replacement cavity partition wall together with the side walls of the blocking plates outside the set of filter screen groups.

[0008] That is, when the two groups of sliding unit plates in a pair of sliding plate groups are slid into the left chamber to form airflow blocking of the left chamber under the drive of the corresponding driving members, the airflow entering from the air inlet can pass through the corresponding airflow redirection channel in front of the pair of sliding plate groups and enter the right chamber, and then pass through the filter screen group corresponding to the right chamber and not blocked by the sliding unit plate to realize next-stage filtration. Through the above structure, the position of the sliding plate group slid into the left chamber or the right chamber can be controlled to select the filter screen group to be used. That is, when the primary filter screen group close to the air inlet in the left chamber is blocked, the sliding unit plates on both sides of the filter screen group can be driven to enter the left chamber to form airflow blocking on both sides of the primary filter screen group, that is, the sliding unit plates, the left chamber and the blocking plates form a closed replacement cavity to isolate the filter screen group in the replacement cavity from the outside. The air entering from the air inlet can pass through the airflow redirection channel in front of the pair of sliding plate groups and enter the right chamber, and then pass through the new primary filter screen group in the right chamber and not blocked by the sliding unit plate to realize filtration. In this way, the filter screen group at each stage along the airflow direction can be replaced to ensure that the device can continue to be used without replacement under the condition that the filter screen group at one stage is blocked, and the problem of manual disassembly is avoided. Meanwhile, the filter screen group at each stage can be fully used, and when the filter screen groups in the left chamber and the right chamber are both blocked, the sliding plate group is slid to the middle of the purification installation shell, and the two ends of the sliding plate group are simultaneously separated from the inner walls of the left chamber and the right chamber. At this time, the airflow can pass through the two filter screen groups at the same time to improve the airflow passing capacity and prolong the service life of the device as a whole to cope with the use under the condition that the replacement is difficult.

[0009] And since the sliding plate group can achieve the blocking of both sides of the filter screen group, it can also form an independent replacement cavity for the subsequent replacement of the filter screen group, that is, even when the device is in use, the cavity door corresponding to this independent replacement cavity can be opened for replacement, so the convenience is better.

[0010] Preferably, the air inlet and the air outlet are each provided with two groups, and are respectively arranged at the two ends of the left chamber and the right chamber, so as to increase the air inlet and air outlet.

[0011] Preferably, the driving member includes a driving screw rod connected to the purification installation shell, and a driving motor for driving the screw rod to rotate, and each group of sliding unit plates is correspondingly threadedly connected with at least two groups of synchronous rotating driving screw rods, so that when the driving motor drives the driving screw rod to rotate, the sliding unit plates can be reciprocatingly and stably alternated between the left chamber and the right chamber, and the use of the driving screw rod can ensure that the sliding unit plates are stable when they form a barrier in the left chamber or the right chamber, that is, there is no need to worry about the loss of driving force due to the failure of the driving motor, which may cause the barrier to fail, and even after the barrier effect is formed, the threads of the driving screw rod itself can meet the driving force barrier.

[0012] Preferably, the filter screen group includes a filter screen layer in the middle and a sealing ring layer connected around the filter screen layer, and the inner wall of the purification installation shell and the blocking plate are further provided with longitudinal T-shaped guide rails for longitudinally sliding installation on both sides of the sealing ring layer. The arrangement of the T-shaped guide rails can not only avoid displacement of the filter screen group when the air flow passes through, but also facilitate the pulling and replacement of the filter screen group during later maintenance and replacement.

[0013] Preferably, the shell of the purification installation shell is further provided with a through port corresponding to the filter screen group, for the filter screen group to pass through, and each through port further extends a core replacement shell, and the core replacement shell is installed with at least two groups of lifting screw rods, which are threadedly connected to the two ends of the blocking plate and used to drive the blocking plate on both sides to lift in the core replacement shell. The blocking plate is further provided with a horizontal T-shaped guide rail for transversely sliding installation on the bottom side of the sealing ring layer. The filter screen group is slidingly installed on the blocking plate through the sealing ring layer, and its two sides are limited by the inner wall of the core replacement shell and lifted to the purification installation shell through the blocking plate. The blocking plate is used to block the through port.

[0014] At this time, the blocking plate is driven by the lifting screw to block the through port outside, which not only ensures the stability of the blocking, but also only needs to start the lifting motor for driving the lifting screw to rotate reversely to pull down the filter screen group into the core replacement shell when it is necessary to disassemble and replace the filter screen group. Since the sliding connection unit plate is located in the chamber to be replaced at this time to achieve the blocking effect, the core replacement shell is only in communication with the space between the two groups of sliding connection unit plates, instead of the whole purification installation shell. Therefore, when the core replacement shell is opened, it will not affect the normal use of the purification installation shell, and the automatic driving of the filter screen group to ascend and descend is more convenient, and the personnel operation is more time-saving and labor-saving, and the safety is better.

[0015] Preferably, a discharge port is formed in the front side wall of the core replacement shell, and a pull door one is installed at the discharge port. When the pull door one is pulled open, an ejection cylinder one installed at the rear side of the core replacement shell is used to eject the filter screen group on the blocking plate through the discharge port transversely out of the core replacement shell, so as to automatically discharge the blocked filter screen group and avoid too much manual intervention.

[0016] Preferably, a feed port is formed in the rear side wall of the core replacement shell, and a pull door two is installed at the feed port. The ejection cylinder one is installed in the pull door two. Since the feed port and the discharge port are separated, the discharge equipment on the front side of the core replacement shell and the feed equipment on the rear side of the core replacement shell can be combined to realize the automatic feeding and discharging of the filter screen group.

[0017] Preferably, a set of material collecting bins are additionally arranged on the front side of the core replacement shell. The material collecting bins are used to receive the blocked filter screen group in the core replacement shell, and a through port one is arranged on the rear side of the material collecting bins. The through port one is blocked by the pull door one between the discharge port. A set of feed bins are additionally arranged on the rear side of the core replacement shell. The feed bins reserve a spare filter screen group, and a through port two is arranged on the front side of the feed bins. The through port two is blocked by the pull door two between the feed port. A set of ejection cylinders two are additionally installed on the rear side of the feed bins and used to eject the spare filter screen group into the core replacement shell.

[0018] Preferably, a set of guide bases are arranged on the bottom of the material collecting bins and the feed bins and connected to the bottom side of the filter screen group in a transverse direction. In this way, the filter screen group can be transversely transitioned between the feed bin, the core replacement shell and the discharge bin, and the positioning is accurate.

[0019] The beneficial effects of the present application are:

[0020] 1、When a pair of sliding plate groups of two groups of sliding unit plates are driven by the driving of the respective driving members to slide into the left chamber to form an airflow barrier of the left chamber, the airflow entering from the air inlet can pass through the corresponding airflow redirection channel on the front side of the pair of sliding plate groups to enter the right chamber, and then pass through the filter screen group corresponding to the outlet of the right chamber without being blocked by the sliding unit plate to enter the next stage of filtration. By controlling the position of the sliding plate group sliding into the left chamber or the right chamber, the filter screen group to be used can be selected. That is, when the primary filter screen group near the air inlet in the left chamber is blocked, the sliding unit plates on both sides of the filter screen group can be driven to enter the left chamber, and an airflow barrier is formed on both sides of the primary filter screen group, that is, the sliding unit plates, the left chamber, and the barrier plate form a closed replacement chamber to isolate the filter screen group inside from the outside. The air entering from the air inlet can pass through the airflow redirection channel on the front side of the pair of sliding plate groups to enter the right chamber and pass through the new primary filter screen group in the right chamber without being blocked by the sliding unit plate. In this way, the filter screen group at each stage along the airflow can be replaced and used, so that the device can continue to be used without stopping for replacement when a primary filter screen group is blocked, and the problem of manual disassembly is avoided. At the same time, it can also ensure that each stage of filter screen group can achieve complete use effect.

[0021] 2、When the filter screen groups in the left chamber and the right chamber are both blocked, the sliding plate group can be slid to the middle of the purification installation shell, and the two ends of the sliding plate group are simultaneously separated from the inner walls of the left chamber and the right chamber. At this time, the airflow can pass through both filter screen groups at the same time to increase the airflow throughput and further prolong the service life of the device as a whole to cope with the use in special situations where replacement is difficult.

[0022] 3、Since the sliding plate group can block both sides of the filter screen group, it can form an independent replacement chamber for subsequent replacement of the filter screen group. Even when the device is in use, the chamber door corresponding to this separate replacement chamber can be opened for replacement, so the convenience is better. BRIEF DESCRIPTION OF DRAWINGS

[0039] Example 1

[0040] ​​​​​​​As Figures 1-3 shown in the figure, a kind of air purification device for ship, in the present embodiment, including the purification installation shell 3 with air inlet 1 and air outlet 2 and a set of barrier plate 4 in the purification installation shell 3, air outlet 2 is equipped with axial flow fan 5, barrier plate 4 is used to separate the space in the purification installation shell 3 into left chamber and right chamber, and four pairs of sliding plate group 6 are also installed in parallel slidingly on it along the airflow direction, the two groups of sliding unit plates of each pair of sliding plate group 6 are synchronously slid into left chamber or right chamber under the drive of corresponding driving element 7, and are sealed with the inner wall of corresponding left chamber or right chamber for blocking airflow, and airflow redirection passage 8 is opened on the barrier plate 4 between the two adjacent pairs of sliding plate group 6 and on the barrier plate 4 between the most edge sliding plate group 6 and air inlet 1 and air outlet 2, a set of filter screen group 9 is arranged in the corresponding left chamber and right chamber between each pair of sliding plate group 6, when the two groups of sliding unit plates of a pair of sliding plate group 6 are synchronously slid into left chamber or right chamber, the two groups of sliding unit plates of the pair of sliding plate group 6 are sealed and abutted with the inner wall of left chamber or right chamber, so as to form replacement cavity partition wall surrounded outside a set of filter screen group 9 with the side wall of barrier plate together;

[0041] That is, when the two groups of sliding units of the pair of sliding plate groups 6 slide into the left chamber under the driving of the respective driving members 7 to form an airflow barrier in the left chamber, the airflow entering from the air inlet 1 can pass through the corresponding airflow redirection channel on the front side of the pair of sliding plate groups 6 into the right chamber, and then pass through the filter screen group 9 corresponding to the outlet in the right chamber without being blocked by the sliding unit, to enter the next level of filtration. With this structure, the position of the sliding plate group 6 sliding into the left chamber or the right chamber can be controlled to select the filter screen group 9 to be used. That is, when the primary filter screen group 9 near the air inlet 1 in the left chamber is clogged, the sliding units on both sides of the filter screen group 9 can be driven to enter the left chamber, forming an airflow barrier on both sides of the primary filter screen group 9, that is, the sliding units, the left chamber, and the barrier plate 4 form a closed replacement chamber to isolate the filter screen group 9 inside from the outside. The air entering from the air inlet 1 can pass through the airflow redirection channel 8 on the front side of the pair of sliding plate groups 6 into the right chamber and pass through the new primary filter screen group 9 in the right chamber without being blocked by the sliding unit. In this way, each level of filter screen group 9 along the airflow path can be replaced and used, ensuring that the device can continue to be used without stopping for replacement when a level of filter screen group 9 is clogged, avoiding the need for manual disassembly. At the same time, it also ensures that each level of filter screen group 9 can achieve full use effect. When both the filter screen group 9 in the left chamber and the filter screen group 9 in the right chamber are clogged, the sliding plate group 6 slides to the middle of the purification installation shell 3, and the two ends simultaneously separate from the inner walls of the left chamber and the right chamber. At this time, the airflow can pass through both filter screen groups 9 simultaneously to increase the airflow throughput and further prolong the service life of the device to cope with special situations where replacement is difficult.

[0042] Since the sliding plate group 6 can block both sides of the filter screen group 9, it can also form an independent replacement chamber for replacing the filter screen group 9. Even when the device is in use, the corresponding chamber door of the independent replacement chamber can be opened for replacement, making it more convenient.

[0043] The air inlet 1 and the air outlet 2 are each provided with two groups, and are respectively arranged at the two ends of the left chamber and the right chamber, thereby increasing the air intake and air outlet.

[0044] The driving member 7 comprises a driving screw rod 71 adaptedly installed in the purification installation shell 3 and a driving motor 72 for driving the driving screw rod 71 to rotate, and each group of sliding unit plates is correspondingly threadedly connected with at least two groups of synchronous rotating driving screw rods 71, so that when the driving motor 72 drives the driving screw rod 71 to rotate, the sliding unit plates can be reciprocally and stably alternated between the left chamber and the right chamber, and the use of the driving screw rod 71 can ensure that the sliding unit plates have better stability when they are slid into the left chamber or the right chamber to form a barrier, that is, the driving force is not lost due to the failure of the driving motor 72, thereby causing the barrier to fail, and even after the barrier effect is formed, the threads of the driving screw rod 71 itself can meet the driving force barrier.

[0045] The filter screen group 9 comprises a filter screen layer 91 located in the middle and a sealing ring layer 92 connected around the filter screen layer 91, and the inner wall of the purification installation shell 3 and the barrier plate 4 are further provided with longitudinal T-shaped guide rails 93 for longitudinally slidingly connecting with both sides of the sealing ring layer 92, and the T-shaped guide rails can not only avoid the displacement of the filter screen group 9 when the air flow passes through, but also facilitate the pulling and replacement of the filter screen group 9 during later maintenance and replacement.

[0046] Embodiment 2

[0047] As shown in Figures 4-6 An air purification device for a ship, in this embodiment, is further limited based on embodiment 1, and the shell of the purification installation shell 3 is further provided with through ports corresponding to the filter screen group 9 and for the filter screen group 9 to pass through, and each through port further extends a core replacement shell 10, the core replacement shell 10 is installed with at least two groups of jacking screw rods 101, the jacking screw rods 101 are threadedly connected and distributed at both ends of a blocking plate 102, and are used to drive the blocking plate 102 located at both sides of the core replacement shell 10 to lift, the blocking plate 102 is further provided with a horizontal T-shaped guide rail 103 for horizontally slidingly connecting with the bottom side of the sealing ring layer 92, the filter screen group 9 is slidingly connected on the blocking plate 102 through the sealing ring layer 92, and both sides thereof are limited by the inner wall of the core replacement shell 10 and lifted into the purification installation shell 3 through the blocking plate 102, and the blocking plate 102 is used to block the outside of the through port;

[0048] At this time, the sealing plate 102, driven by the lifting screw 101, blocks the passage outside, ensuring the stability of the blockage. When it is necessary to disassemble and replace the filter assembly 9, it is only necessary to start the lifting motor that drives the lifting screw 101 to rotate the screw in the opposite direction. The sealing plate 102 can then pull the filter assembly 9 down into the filter replacement housing 10. Since the sliding plate assembly 6 is located in the chamber to be replaced to achieve the blocking effect, the filter replacement housing 10 is only connected to the space between the two sliding unit plates of the sliding plate assembly 6, rather than the entire purification installation housing 3. Therefore, opening the filter replacement housing 10 will not affect the normal use of the purification installation housing 3. The automated lifting and disassembly of the filter assembly 9 is also more convenient, and the operation is more time-saving, labor-saving, and safer.

[0049] Example 3

[0050] like Figures 7-11 As shown, a ship air purification device, in this embodiment, is a further limitation based on embodiment 2. A discharge port is provided on the front side wall of the filter element housing 10, and a pull-out door 104 is installed at the discharge port. When the pull-out door is pulled open, the ejector cylinder 105 installed on the rear side of the filter element housing 10 is used to push the filter screen group 9 located on the sealing plate 102 through the discharge port and out of the filter element housing 10, thereby achieving the purpose of automatically discharging the blocked filter screen group 9 and avoiding excessive manual intervention.

[0051] A feed inlet is provided on the rear side wall of the core changing housing 10. A pull-out door 106 is installed at the feed inlet, and an ejector cylinder 105 is installed inside the pull-out door 106. Since the feed inlet and discharge outlet are separated, it is easy to combine with the discharge device on the front side and the feed device on the rear side of the core changing housing 10 to realize the automatic loading and unloading of the filter screen group 9.

[0052] A receiving hopper 107 is added to the front side of the core replacement housing 10. The receiving hopper 107 is used to receive the filter screen group 9 that is blocked in the core replacement housing 10. A through port 1 is provided on the rear side of the receiving hopper 107. The through port 107 is separated from the discharge port by a pull-out door 104. A feeding hopper 108 is added to the rear side of the core replacement housing 10. The feeding hopper 108 stores spare filter screen groups 9. A through port 2 is provided on the front side of the feeding hopper 108. The through port 2 is separated from the feed port by a pull-out door 2 106. A set of ejection cylinder 2 109 is also installed on the rear side of the feeding hopper 108 to push the spare filter screen group 9 into the core replacement housing 10.

[0053] Both the receiving hopper 107 and the feeding hopper 108 are provided with a set of guide bases 1010 that are laterally connected to the bottom of the filter screen group 9. This ensures that the filter screen group 9 can move laterally when transitioning between the feeding hopper 108, the core replacement housing 10 and the discharge hopper, thus ensuring accurate positioning.

[0054] The working principle of the present application is as follows:

[0055] In the present application, when the two groups of sliding units of the pair of sliding plate groups 6 slide into the left chamber under the driving of the respective driving members 7 to form the airflow barrier of the left chamber, the airflow entering from the air inlet 1 can pass through the corresponding airflow redirection channel on the front side of the pair of sliding plate groups 6 to enter the right chamber, and then pass through the filter screen group 9 corresponding to the outlet and without the barrier of the sliding unit to enter the next stage of filtration. With this structure, the position of the sliding plate groups 6 sliding into the left chamber or the right chamber can be controlled to select the filter screen group 9 to be used. That is, when the primary filter screen group 9 near the air inlet 1 in the left chamber is clogged, the sliding units on both sides of the filter screen group 9 can be driven to enter the left chamber, forming an airflow barrier on both sides of the primary filter screen group 9, i.e., the sliding units, the left chamber, and the barrier plate 4 form a closed replacement chamber to isolate the filter screen group 9 inside from the outside. The air entering from the air inlet 1 can pass through the airflow redirection channel port 8 on the front side of the pair of sliding plate groups 6 to enter the right chamber and pass through the new primary filter screen group 9 without the barrier of the sliding unit in the right chamber. In this way, the filter screen group 9 at each stage along the airflow can be replaced and used, thereby ensuring that the device can continue to be used without replacement when the primary filter screen group 9 is clogged, avoiding the need for manual disassembly, and ensuring that each stage of the filter screen group 9 can be fully used. When both the filter screen group 9 in the left chamber and the filter screen group 9 in the right chamber are clogged, the sliding plate groups 6 slide to the middle of the purification installation shell 3, and the two ends simultaneously separate from the inner walls of the left chamber and the right chamber. At this time, the airflow can pass through both filter screen groups 9 simultaneously to increase the airflow throughput and further prolong the service life of the device to cope with the use of special situations where replacement is difficult.

[0056] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements of some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
