Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a vacuum chamber filtration structure. Background Technology

[0002] In industrial production, vacuum chambers are commonly used to adsorb workpieces and perform processing operations. Debris and dust generated during processing can easily enter the air pump with the airflow, affecting the pump's lifespan and the working environment. Therefore, filters are typically installed before the gas enters the pump. Existing filters often use a metal mesh welded to a rectangular support structure, then horizontally inserted into the airflow channel for filtration across a single cross-section. This method suffers from poor filtration efficiency, insufficient sealing, difficulty in cleaning, and susceptibility to clogging.

[0003] Therefore, there are still shortcomings and deficiencies in the existing technology. How to provide a vacuum chamber filter structure with good filtration effect and easy cleaning is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum chamber filter structure that solves the technical problems of existing filters, which mostly use metal mesh welded to a rectangular support structure and installed in the airflow channel by horizontal insertion, resulting in poor filtration effect and difficult cleaning due to the use of a single cross-section of the flow channel.

[0005] To achieve the above objectives, this utility model provides a vacuum cavity filtration structure, comprising:

[0006] The mounting component has a filter chamber and an air intake transition chamber inside. The mounting component has an air inlet and an air outlet on both sides. The air inlet is connected to the filter chamber, and the air outlet is connected to the air intake transition chamber.

[0007] A filter is detachably disposed within the filter chamber, the filter comprising a filter cylinder and a flexible filter screen sleeved outside the filter cylinder;

[0008] The filter chamber is equipped with a filter pipe, one end of which is connected to the air intake transition chamber, and the other end is sealed to one end of the filter cylinder. The other end of the filter cylinder is sealed by a cover plate.

[0009] Preferably, the filter cylinder is provided with sealing strips at both ends, and the flexible filter screen is fixed to the filter cylinder by the sealing strips.

[0010] Preferably, the mounting component has a mounting port at its bottom, through which the filter is installed in the filter chamber.

[0011] Preferably, a limiting plate is fixedly provided at one end of the filter pipe that communicates with the filter cylinder, and the filter cylinder is sleeved outside the limiting plate.

[0012] Preferably, the limiting plate is cross-shaped.

[0013] Preferably, a screw is fixedly provided at the end of the limiting plate away from the filter pipe, the cover plate is sleeved on the screw, and the end of the screw away from the limiting plate extends out of the mounting part through the mounting port.

[0014] Preferably, a handle is threadedly connected to one end of the screw that extends beyond the mounting component.

[0015] Preferably, a sealing ring is provided at the mounting port.

[0016] Preferably, the size of the end of the filter pipe that communicates with the filter cylinder is the same as the size of the filter cylinder.

[0017] Preferably, the filter pipe is L-shaped.

[0018] Compared to the aforementioned background technology, the vacuum chamber filter structure provided by this utility model features a filter that is detachably installed within the filter chamber of the mounting component. When cleaning is required, the filter can be removed from the mounting component. Users can choose to replace or clean the flexible filter screen outside the filter cartridge, making cleaning convenient.

[0026] 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.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This utility model provides a vacuum chamber filtration structure that uses a flexible filter screen 22 to filter out debris and dust in the airflow, thus preventing debris and dust from entering the air pump with the airflow, improving the filtration effect, effectively ensuring the air quality in the production workshop, and the filter 2 is easy to clean and does not easily affect the flow rate.

[0029] Please refer to this as well. Figures 1 to 4 The vacuum chamber filtration structure provided by this utility model includes:

[0030] Mounting component 1 has a filter chamber 11 and an air intake transition chamber 12 inside. The mounting component 1 has an air inlet 13 and an air outlet 14 on both sides. The air inlet 13 is connected to the filter chamber 11, and the air outlet 14 is connected to the air intake transition chamber 12.

[0031] The filter 2 is detachably disposed in the filter chamber 11. The filter 2 includes a filter cylinder 21 and a flexible filter screen 22 sleeved outside the filter cylinder 21.

[0032] The filter chamber 11 is fixedly provided with a filter pipe 15. One end of the filter pipe 15 is connected to the air intake transition chamber 12, and the other end is sealed to one end of the filter cylinder 21. The other end of the filter cylinder 21 is sealed by a cover plate 16.

[0033] The air inlet 13 is used to communicate with the vacuum chamber, and the air outlet 14 is used to connect with the air pump. When the air pump is working, it draws air through the air outlet 14. The gas in the vacuum chamber first enters the filter chamber 11 through the air inlet 13. The filter 2 is installed in the filter chamber 11. The bottom end of the filter cylinder 21 is sealed by the cover plate 16. The gas can only pass through the flexible filter screen 22 and the filter holes on the side of the filter cylinder 21 in sequence to enter the interior of the filter cylinder 21. The gas filtered by the flexible filter screen 22 enters the suction transition chamber 12 through the filter pipe 15 from the inside of the filter cylinder 21, and finally enters the air pump through the air outlet 14.

[0034] This design allows the flexible filter 22 to filter out debris and dust from the airflow, preventing them from entering the air pump and improving filtration efficiency, thus effectively ensuring air quality in the production workshop. Furthermore, the filter 2 is detachably installed within the filter chamber 11 of the mounting component 1. When cleaning is required, the filter 2 can be removed from the mounting component 1, allowing users to easily replace or clean the flexible filter 22 outside the filter cartridge 21.

[0035] The filter cartridge 21 has a long cylindrical structure, which can increase the filterable cross-sectional area. On the other hand, since most of the filter cross-section is staggered from the air inlet 13, foreign objects will only block the mesh of the flexible filter screen 22 from the side closest to the air inlet 13, without affecting the flow rate.

[0036] In this embodiment, the mounting component 1 is a welded structure. The mounting component 1 is generally rectangular box-shaped, but it can also be other shapes, such as cylindrical, etc. It can be set according to actual needs and is not limited in specific terms.

[0037] In some embodiments, please refer to the following: Figure 1 and Figure 4 The filter cylinder 21 is provided with sealing strips 23 at both ends, and the flexible filter screen 22 is fixed to the filter cylinder 21 by the sealing strips 23.

[0038] The filter cartridge 21 is a metal structure, and the flexible filter screen 22 is sleeved on the outside of the filter cartridge 21. The flexible filter screen 22 is fixed by the sealing strips 23 at both ends of the filter cartridge 21, so the flexible filter screen 22 is detachably installed on the filter cartridge 21. When cleaning or replacing, the flexible filter screen 22 can be easily removed from the filter cartridge 21.

[0039] In some embodiments, please refer to the following: Figures 1 to 3 The bottom of the mounting component 1 is provided with a mounting port 17, and the filter 2 is installed in the filter chamber 11 through the mounting port 17.

[0040] The mounting port 17 is located at the bottom of the mounting component 1 and is connected to the filter chamber 11 inside the mounting component 1. The cover plate 16 is set at the mounting port 17. When the filter 2 is installed in the filter chamber 11, the cover plate 16 can close the mounting port 17 and at the same time, the cover plate 16 can close one end of the bottom of the filter cylinder 21, ensuring that the gas can flow to the outlet 14 through the filter pipe 15 after being filtered by the flexible filter screen 22.

[0041] In some embodiments, please refer to the following: Figures 1 to 3 The filter pipe 15 is fixedly provided with a limiting plate 18 at one end for communicating with the filter cylinder 21, and the filter cylinder 21 is sleeved on the limiting plate 18.

[0042] Specifically, the filter pipe 15 is welded inside the mounting component 1, and the limiting plate 18 is welded to the filter pipe 15. The limiting component is used to position the filter cylinder 21, which facilitates the installation of the filter 2.

[0043] In some embodiments, please refer to the following: Figures 1 to 3 The limit plate 18 is cross-shaped.

[0044] The cross-shaped limiting plate 18 is set vertically, and its top end is connected to the filter pipe 15. The two intersecting spokes of the cross-shaped limiting plate 18 provide sufficient strength to support and fix the filter 2, preventing the filter 2 from shaking, shifting, or rotating during operation, thus ensuring reliability. Moreover, the cross-shaped structure minimizes airflow obstruction, retaining almost 95% or more of the cross-sectional area of ​​the entire pipe for airflow passage.

[0045] In addition, the bottom end of the cross-shaped limiting plate 18 is chamfered to facilitate the installation of the filter cartridge 21 on the outside of the limiting plate 18.

[0046] In some embodiments, please refer to the following: Figures 1 to 3 A screw 19 is fixedly provided at the end of the limiting plate 18 away from the filter pipe 15, and a cover plate 16 is sleeved on the screw 19. The end of the screw 19 away from the limiting plate 18 extends out of the mounting part 1 through the mounting port 17.

[0047] The screw 19 is fixed vertically at the bottom of the limiting plate 18. The cover plate 16 has a through hole in the center, and the screw 19 passes through the through hole to the cover plate 16.

[0048] In some embodiments, please refer to the following: Figures 1 to 2 The end of the screw 19 extending out of the mounting part 1 is threadedly connected to a handle 191.

[0049] After the filter 2 is installed inside the filter chamber 11 by fitting it onto the limiting plate 18 through the installation port 17, the top end of the filter cylinder 21 is connected to one end of the filter pipe 15. Rotating the handle 191 moves the handle 191 on the screw 19. Tightening the handle 191 presses the cover plate 16 against the installation port 17. Since the size of the cover plate 16 is larger than the size of the installation port 17, the installation port 17 is closed by the cover plate 16. At the same time, the cover plate 16 presses against the bottom of the filter 2, thus sealing the bottom of the filter cylinder 21. Because the filter 2 is pressed between the cover plate 16 and the filter pipe 15, the sealing strip 23 at the top of the filter cylinder 21 deforms under force and makes full contact with the filter pipe 15. The sealing strip 23 at the bottom of the filter 2 also deforms under force and makes full contact with the cover plate 16. The top and bottom ends of the filter 2 form a good seal with the filter pipe 15 and the cover plate 16, respectively, effectively preventing foreign objects from entering the air pump through gaps and causing malfunctions. The enhanced sealing of the filter 2 increases the service life of the air pump.

[0050] In some embodiments, please refer to the following: Figures 1 to 3 A sealing ring 171 is provided at the installation port 17.

[0051] The sealing ring 171 is attached around the mounting port 17. When the handle 191 is tightened to press the cover plate 16 into the mounting port 17, the cover plate 16 presses the sealing ring 171. After the sealing ring 171 is deformed by force, a good seal is formed between the cover plate 16 and the mounting port 17. Thus, the filter chamber 11 will not communicate with the outside through the gap between the cover plate 16 and the mounting port 17. When the filter 2 is used for filtration, foreign objects in the filter chamber 11 will not leak into the outside atmosphere, effectively ensuring the air quality of the production workshop.

[0052] In some embodiments, please refer to the following: Figures 1 to 4 The size of the end of the filter pipe 15 that is connected to the filter cylinder 21 is the same as the size of the filter cylinder 21.

[0053] The filter pipe 15 is welded into the mounting part 1. One end of the filter pipe 15 is connected to the air intake transition chamber 12. The airflow can only be filtered by the filter 2 and then enter the air intake transition chamber 12 through the filter pipe 15.

[0054] The filter pipe 15 has a round pipe structure. When the handle 191 is tightened to press the cover plate 16 against the filter 2, the top end of the filter cylinder 21 is connected to the bottom end of the filter pipe 15. The sealing strip 23 at the top of the filter cylinder 21 is deformed by force and makes full contact with the filter pipe 15. The top end of the filter cylinder 21 and the filter pipe 15 form a good seal to ensure the sealing effect.

[0055] In some embodiments, please refer to the following: Figures 1 to 2 The filter pipe 15 is L-shaped.

[0056] The right end of the filter pipe 15 is connected to the air intake transition chamber 12, and the lower end of the filter pipe 15 is connected to the top end of the filter cylinder 21. The shape of the filter pipe 15 is not limited to this; it can also be arc-shaped, etc., and there is no specific limitation.

[0057] Please refer to this as well. Figures 1 to 4 The vacuum chamber filter structure provided by this utility model is installed by first fitting the filter 2 onto the limiting plate 18 through the mounting port 17 at the bottom of the mounting component 1, then fitting the cover plate 16 onto the screw 19, and finally tightening the handle 191 to seal the mounting port 17 and press the filter 2 firmly. When the filter 2 needs to be cleaned, simply unscrew the handle 191 from the screw 19, remove the cover plate 16, and pull the filter 2 out for cleaning, which is very convenient.

[0058] During operation, the air pump draws air from the outlet 14. The air mixed with debris and dust in the vacuum chamber enters the filter chamber 11 from the inlet 13. After passing through the filter 2, the debris and dust are filtered out. The air enters the suction transition chamber 12 through the filter pipe 15 and finally enters the air pump through the outlet 14 for discharge.

[0059] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0060] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
