Description

Filter device

Technical Field

The present invention relates to a filter device, and more particularly, to a filter device for a clean room.

Background

In the current semiconductor factory, a fan filter set is installed to clean the air quality of the environment and ensure the specification of the clean room.

However, in the conventional fan filter assembly, the housing for accommodating the fan assembly is formed by screwing or welding a plurality of plate bodies, so when the fan device is in operation, each plate body is easy to vibrate, and the fan filter assembly generates great noise in use.

Furthermore, since the conventional fan filter assembly is mounted on the frame of the ceiling, when the board body vibrates, the fan filter assembly and the frame are easily loosened, so that an unexpected gap is generated between the fan filter assembly and the frame, which results in poor air filtration or a problem of exhaust gas flowing back to the clean room.

Therefore, the various defects of the prior art have become a difficult problem to overcome in the industry.

Disclosure of Invention

In view of the above-mentioned drawbacks of the prior art, the present invention provides a filtering apparatus, comprising: the housing is an integrally formed groove-shaped structure, which has a first side and a second side opposite to each other and an accommodation space defined by the groove-shaped structure; a filter assembly disposed on the first side of the housing; an action component accommodated in the accommodation space and fixed on the second side of the housing; and a guiding member accommodated in the accommodating space and fixed on the housing.

In the filtering apparatus, an opening is formed on the first side of the housing as an outlet port, and the filtering component covers the opening.

In the filtering apparatus, the second side of the housing is formed with a through hole as an inlet port, and the acting component is mounted at the through hole.

In the filtering apparatus, ribs are formed on the surface of the housing.

In the filtering apparatus, a filter is disposed on the second side of the housing corresponding to the action component.

In the filtering apparatus, the filtering component includes a filtering net structure.

In the above-mentioned filtering apparatus, the acting assembly includes a fan structure, a supporting member for supporting the fan structure on the housing, and a shaft member coupled to the supporting member to rotate the fan structure.

In the filtering apparatus, the guiding member is used to cover the cover of the acting component.

In the filtering apparatus, the guiding member has a plate and a retaining wall vertically installed on the side of the plate, and the retaining wall has a notch as the outlet.

The filter apparatus further includes an electronic device for actuating the active component. For example, the top end of the retaining wall is bent outward to form a plate, and each plate is formed with a plurality of third fixing holes for fixing the guiding member to the housing by bolts passing through the third fixing holes and a plurality of fourth fixing holes on the bottom surface of the accommodating space of the housing.

Therefore, the filtering apparatus of the present invention is designed by integrally forming the housing, so as to prevent the housing from vibrating during the operation of the acting component, thereby increasing the structural strength of the filtering apparatus, reducing the vibration and noise problems, and preventing the frame of the ceiling from loosening from the filtering apparatus to cause an unexpected gap between the frame and the filtering apparatus, thereby effectively preventing the problems of poor air filtration or exhaust gas from flowing back to the room.

Fig. 1A to 2D are schematic views of a filter apparatus 1 of the present invention. The filtering apparatus 1 comprises: a housing 10, a filter element 11, an active element 12 and a guide 15.

The housing 10 is a trough-shaped structure formed by an integral forming method, and the trough-shaped structure is formed with a containing space S with a symmetrical outline, the cross section of the embodiment is square, and can also be round or other regular polygon, and it has a first side 10a and a second side 10b opposite to each other, the first side 10a is located at one side of the containing space S, i.e. the side close to the filtering component 11, and the second side 10b is located at the other side of the containing space S, i.e. the side close to the acting component 12.

In the present embodiment, the contour of the first side 10a of the housing 10 is a symmetrical shape, the cross-section of the present embodiment is a square, and the area (cross-sectional area) a1 of the first side 10a is larger than the area (cross-sectional area) a2 of the second side 10B, as shown in fig. 2B. For example, the first side 10a is formed with an opening 100 as an air outlet, and the second side 10b is formed with a through hole 101 as an air inlet in the middle. Thus, the first side 10a of the housing 10 serves as an outlet port for the airflow, and the second side 10b of the housing 10 serves as an inlet port for the airflow. Understandably, the size of the housing 10 is determined according to the requirement, and the area (sectional area) a1 of the first side 10a of the embodiment is 1200 cm × 1200 cm.

Furthermore, the housing 10 is formed with a plurality of ribs 103, such as a net shape at the bottom of the groove as shown in fig. 1B, and extending to the side of the groove (such as a grid shape as shown in fig. 1B), which not only increases the strength, but also reduces the vibration and noise problems. It should be understood that the ribs 103 may also be disposed inside the housing 10.

Furthermore, a filter 13 is disposed on the second side 10b of the housing 10, which corresponds to the position of the active component 12. For example, the screen 13 is located at the through hole 101. It should be understood that the type and specification of the filter 13 are not particularly limited.

The filter assembly 11 is disposed on the first side 10a of the housing 10 and is in close contact with the periphery of the first side 10 a.

In the present embodiment, the filtering component 11 includes a filtering structure 11a covering the opening 100, so that the airflow enters the accommodating space S, passes through the filtering structure 11a, and enters a room such as a laboratory or a clean room. It should be understood that the filter assembly 11 is not limited to the above-described types.

Furthermore, at least one positioning member 102 (such as a quadrangular ring strip shown in FIG. 1C or other suitable structures) can be disposed at the edge or corner of the opening 100 of the housing 10. For example, the filter element 11 abuts against the inner edge of the positioning member 102, so as to assemble the filter element 11 on the first side 10a of the housing 10 in a close contact manner.

The acting component 12 is disposed in the accommodating space S and erected at the through hole 101 to be fixed on the second side 10b of the housing 10, as shown in fig. 2A.

In the present embodiment, the active component 12 is in the form of a fan. For example, the active component 12 includes a fan structure 12a, a shaft 120 for rotating the fan structure 12a, and a support 121 for mounting the fan structure 12a on the housing 10. Specifically, the supporting member 121 is a disk-shaped member, and is fixed to a plurality (e.g., six) of first fixing holes 107 at the edge of the through hole 101 at the second side 10B of the casing 10, so as to pass through a plurality of second fixing holes 127 (shown in fig. 1C and 2C) at the edge of the supporting member 121 and the first fixing holes 107 of the casing 10 by bolts (not shown) to fix the acting assembly 12 on the bottom surface 10D of the casing 10, and the supporting member 121 has a through hole 123 such that the filter 13 is covered on the through hole 123, as shown in fig. 1B and 2D. It should be understood that the fan structure 12a is not particularly limited with respect to its variety.

Furthermore, as shown in fig. 1C and 2A, an electronic device 14 may be disposed in the housing 10 as required to actuate the shaft 120 of the active element 12. For example, the electronic device 14 includes a circuit board to electrically control the active component 12.

The guiding member 15 is a cover body, which is disposed in the receiving space S and fixed between the filtering component 11 and the acting component 12.

In this embodiment, the guide 15 is used to cover one side of the active component 12, as shown in FIG. 2A. For example, the guide 15 is coupled to the shaft 120 and receives the fan structure 12a, such that the guide 15 is disposed corresponding to the acting assembly 12. Specifically, the shaft 120 is disposed with a bearing seat 124, the guiding member 15 has a plate 150 joined to the bearing seat 124 and a plurality of (e.g. four) retaining walls 151 erected on the plate 150, and each retaining wall 151 is formed with a notch as an outlet 152 for guiding the airflow of the fan structure 12a to flow to the wall 10c of the housing 10 in the lateral direction of the receiving space S through the outlet 152.

Furthermore, as shown in fig. 3A and 3B, the plate 150 has a first surface 150a and a second surface 150B opposite to each other and a mounting hole 153 communicating the first surface 150a and the second surface 150B, so that the guide 15 is coupled to the bearing seat 124 through the mounting hole 153, and the second surface 150B of the plate 150 faces the filter assembly 11, so that the fan structure 12a is located between the first surface 150a and the support 121. For example, the bearing seat 124 can be configured with a positioning plate 125 having a plurality of first positioning holes 126 (as shown in fig. 1C and fig. 2C), and a plurality of (e.g., four) second positioning holes 156 corresponding to the first positioning holes 126 are configured around the mounting hole 153, so that bolts (not shown) can pass through the first positioning holes 126 and the second positioning holes 156 to fix the plate 150 on the bearing seat 124.

Furthermore, the first surface 150a of the plate 150 is substantially a quadrilateral plane, and the retaining walls 151 are in a streamline shape to respectively stand on the sides of the first surface 150a of the plate 150, so that the four outlet ports 152 of the guiding member 15 are located between the first surface 150a of the plate 150 and two adjacent retaining walls 151, and face different directions, as shown in fig. 3B, to guide the airflow of the fan structure 12a to four different directions. For example, each of the outlet ports 152 is located at a corner of the first surface 150a of the board 150. Specifically, the outlet ports 152 on two opposite sides are symmetrically distributed, so that the airflow generated by the fan structure 12A will flow toward the wall 10c of the accommodating space S of the housing 10, and the airflow will hit the wall 10c and turn to form a vortex flow V (as shown in fig. 2A), and then flow toward the filter assembly 11.

In addition, a plate 154 is bent and protruded from the top of the retaining wall 151, and a plurality of (e.g. four) third fixing holes 155 are disposed on each plate 154, so that bolts (not shown) can pass through the third fixing holes 155 and the fourth fixing holes 106 on the bottom surface 10d of the accommodating space S of the housing 10 to fix the guiding member 15 on the housing 10.

In use of the filter device 1, the filter device 1 is placed with the first side 10a of the housing 10 on a target frame (not shown) with the filter element 11 facing a target space (e.g. a laboratory or clean room). Then, the fan structure 12a of the active component 12 is activated to generate an airflow, so that the external air a flows toward the filter component 11 (the airflow direction f1 shown in fig. 1A), i.e., the external air a is sucked into the accommodating space S of the housing 10 from the through hole 101 on the second side 10b of the housing 10, and then flows toward the filter component 11 through the four outlet ports 152 of the guiding member 15, so as to be discharged after filtering (the airflow direction f2 shown in fig. 1A) to a predetermined region (such as a laboratory or a clean room) of the target space, so that the gas discharged by the filter device 1 conforms to the relevant regulations of the laboratory (or clean room).

In summary, the filtering apparatus 1 of the present invention is mainly formed by integrally forming the housing 10 and having the ribs 103, so that when the acting component 12 operates, the housing 10 can be prevented from vibrating, which not only increases the structural strength of the filtering apparatus 1, but also reduces the vibration and noise problems, and can prevent the target frame from loosening from the filtering apparatus 1 to cause an unexpected gap between the target frame and the filtering component 11, thereby effectively preventing the problems of poor air filtration or waste gas entering the laboratory or clean room.

Furthermore, by the design of the guiding member 15, the airflow (including the external air a) generated by the fan structure 12a forms a vortex flow V, so that the airflow (including the external air a) generated by the fan structure 12a continuously advances in the form of the vortex flow V and flows toward the filtering element 11, so that the vortex flow V can throw away the smaller foreign matters (such as particles that the filtering element 11 cannot filter) in the airflow (including the external air a) (such as throwing the smaller foreign matters onto the wall surface 10 c), and further filter the larger foreign matters through the filtering element 11. Therefore, the filter apparatus 1 can effectively improve the cleanliness of the gas discharged therefrom.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
