[0002] During the production and use of hot melt adhesives, especially in laboratory environments, waste gases containing harmful substances are generated. If these waste gases are emitted directly without treatment, they will adversely affect the environment and the health of laboratory personnel. Therefore, filtration of the waste gases is necessary. For example, Chinese patent CN 219560858U discloses a hot melt adhesive constant temperature heating device that uses activated carbon to filter the waste gases. While this method can treat the waste gases, activated carbon has a limited lifespan, requiring periodic filter replacement. Furthermore, replacing the filter requires a significant downtime, making filter replacement difficult and inefficient. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-9 As shown, this utility model provides the following technical solution:

[0029] A hot melt adhesive laboratory exhaust gas filtration device includes a housing 1. An exhaust 3 and an inlet 2 are respectively connected to the top and bottom of the housing 1. An exhaust channel for transporting exhaust gas along a preset path is formed between the exhaust 3, the housing 1, and the inlet 2. A horizontally movable filter 6 is installed inside the housing 1. The filter 6 includes a frame portion. One side of the frame portion is open to form two slots 62. The top and bottom of the frame portion are open to form air guide holes 63. A detachable filter portion is installed inside each of the two slots 62. A telescopic member 5 is installed on the housing 1. The telescopic end of the telescopic member 5 is connected to the frame portion. By telescopically extending and retracting the telescopic member 5, one slot 62 is located outside the housing 1, and the other slot 62 is located inside the housing 1.

[0030] With the above technical solution, when personnel need to filter the exhaust gas discharged from the hot melt adhesive laboratory, the exhaust gas pipe is connected to the air inlet 2, and the filter part is inserted into the slot 62 on one side of the frame part. After the filter part is inserted, the telescopic component 5 works, thereby driving the frame part to move, so that the frame part moves one filter part into the frame part. After the exhaust gas is delivered to the air inlet 2, the air inlet 2 guides the exhaust gas to the inside of the housing part 1, where the exhaust gas is filtered by the filter part on the frame part. After the exhaust gas is filtered, the filtered gas is discharged through the air outlet 3. When personnel need to replace the filter part, the telescopic component 5 works, thereby driving the frame part to move the used filter part to the outside of the housing part 1, and moving another unused filter part into the inside of the housing part 1. This allows the device to work normally, and personnel do not need to stop for a long time when replacing the filter part, thus improving the replacement efficiency of the filter part.

[0031] Furthermore, when personnel need to replace the filter, in order to facilitate automatic removal of the filter, such as... Figures 1-3 , Figure 6 As shown, the device also includes a pusher 4 for pushing the filter section. The pusher 4 includes a side plate 41, which is fixedly connected to one side of the housing 1. A first electric push rod 42 is fixedly connected to the side of the side plate 41 away from the housing 1. The telescopic end of the first electric push rod 42 is connected to a pusher rod 43.

[0032] In this embodiment, after the used filter part moves to the outside of the housing 1 along with the frame part, the housing 1 supports the side plate 41, and the side plate 41 supports the first electric push rod 42. The first electric push rod 42 works, thereby driving the push rod 43 to move. The push rod 43 pushes the filter part inside the frame part, thereby moving the filter part to the outside of the frame part. This eliminates the need for personnel to manually remove the filter part, reducing the difficulty of removing the filter part and improving the removal efficiency of the filter part.

[0033] Specifically, in one embodiment, regarding the aforementioned housing component 1, as... Figures 1-4 As shown, the housing component 1 includes an outer shell 11, with a base 12 fixedly connected to the bottom of the outer shell 11 for supporting itself, and a cavity is formed horizontally on the outer shell 11 to accommodate the frame portion.

[0034] In this embodiment, the outer casing 11 is supported by the base 12, and the frame portion is supported by the outer casing 11. The frame portion moves by the operation of the telescopic member 5, causing the frame portion to move a filter portion into the interior of the outer casing 11. After the exhaust gas is delivered to the air inlet 2, the exhaust gas is guided by the air inlet 2 and delivered into the interior of the outer casing 11. The exhaust gas is filtered by the filter portion on the frame portion. After filtration, the filtered gas is discharged through the air outlet 3. When the filter portion needs to be replaced, the frame portion moves by the operation of the telescopic member 5, causing the frame portion to move the used filter portion to the outside of the outer casing 11, and causing another unused filter portion to move into the interior of the outer casing 11.

[0035] Furthermore, in this utility model, regarding the aforementioned frame portion, as follows: Figures 8-9 As shown, the frame portion includes a mounting shell 61, a slot 62 formed on one side of the mounting shell 61, and air vents 63 formed on the top and bottom of the mounting shell 61, with the air vents 63 communicating with the slot 62.

[0036] In this embodiment, when the telescopic member 5 is working, it drives the mounting shell 61 to move, and the mounting shell 61 drives the filter part inside the slot 62 to move. When the filter part moves into the outer shell 11, the air guide hole 63 on the mounting shell 61 connects with the air inlet 2 and the air outlet 3, so that the exhaust gas can be filtered. The telescopic member 5 drives the mounting shell 61 to move, and the mounting shell 61 drives the filter part inside the slot 62 to move. When the filter part moves to the outside of the outer shell 11, the personnel can replace the filter part.

[0037] When the mounting housing 61 is inside the outer casing 11, in order to increase the sealing between the mounting housing 61 and the outer casing 11, such as Figures 8-9 As shown, sealing rings 64 are bonded to both the top and bottom of the mounting shell 61, and the air vent 63 is located inside the sealing rings 64.

[0038] Specifically, in one embodiment, regarding the aforementioned telescopic member 5, as... Figures 1-3 and Figure 7 As shown, the telescopic component 5 includes a second electric push rod 51, which is fixedly connected to the top of the housing 11. The telescopic end of the second electric push rod 51 is connected to a moving rod 52. A connecting plate 53 is fixedly connected to the top of the mounting housing 61, and the free end of the moving rod 52 is fixedly connected to the connecting plate 53.

[0039] In this embodiment, when it is necessary to move the mounting shell 61, the second electric push rod 51 is activated, thereby causing the second electric push rod 51 to move the moving rod 52, which in turn moves the connecting plate 53, causing the connecting plate 53 to move the mounting shell 61.

[0040] Furthermore, regarding how the aforementioned filtration section works in this invention, as follows: Figures 8-9 As shown, the filtration section includes a metal mesh filter element 65, a HEPA filter element 66, and an activated carbon filter element 67. The HEPA filter element 66 is located between the metal mesh filter element 65 and the activated carbon filter element 67, and the metal mesh filter element 65 is located above the HEPA filter element 66.

[0041] In this embodiment, when the exhaust gas is delivered to the inside of the housing 11, it is filtered by the metal mesh filter element 65, the HEPA filter element 66 and the activated carbon filter element 67, thereby treating the exhaust gas. The treated exhaust gas is discharged through the exhaust element 3.

[0042] Specifically, in one embodiment, regarding the aforementioned air intake 2, as... Figures 1-3 and Figure 5 As shown, the air intake component 2 includes an air guide pipe 21, which is fixedly connected to the bottom of the housing 11, and a side pipe 22 is fixedly connected to one side of the air guide pipe 21.

[0043] In this embodiment, the pipe for conveying exhaust gas is connected to the side pipe 22. After the exhaust gas is conveyed into the side pipe 22, it is conveyed into the air guide pipe 21. The exhaust gas is then guided into the housing 11 through the air guide pipe 21, and then filtered through the metal mesh filter element 65, the HEPA filter element 66 and the activated carbon filter element 67.

[0044] Specifically, in one embodiment, regarding the aforementioned air outlet 3, as... Figures 1-3 and Figure 5 As shown, the air outlet component 3 includes an air outlet pipe 31, which is fixedly connected to the top of the housing 11, and an exhaust hood 32 is fixedly connected to the top of the air outlet pipe 31. An exhaust fan 33 is installed inside the exhaust hood 32.

[0045] In this embodiment, after the exhaust gas is filtered, the exhaust fan 33 operates, thereby guiding the gas flow inside the exhaust hood 32 and allowing the gas to be discharged through the exhaust hood 32, thereby improving the gas discharge efficiency.

[0046] When exhaust gas enters the air duct 21, a structure is installed to reduce the exhaust gas flow rate in order to improve the filtration efficiency during gas filtration, such as... Figure 5 As shown, multiple conical covers 23 are fixedly connected from top to bottom inside the air duct 21. The diameter of the bottom of the conical cover 23 is smaller than the diameter of its top.

[0047] In this embodiment, when the gas flows into the gas duct 21, the conical cover 23 is used to reduce the gas flow rate, thereby increasing the time the gas spends passing through the metal mesh filter 65, HEPA filter 66 and activated carbon filter 67, thus improving the degree of gas filtration.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
