Description

Filter equipment

This creation is about a kind of filtering equipment, especially a kind of filtering equipment used in clean rooms.

At present, all semiconductor factories are equipped with fan filter units to clean the air quality of the environment and ensure the specifications of the clean room.

However, in the conventional fan filter unit, the casing used to house the fan unit is composed of multiple plates that are screwed or welded. Therefore, when the fan device is in operation, each of the plates is likely to vibrate, causing the fan to filter The group generates a lot of noise in use.

Furthermore, since the conventional fan filter unit is installed on the frame of the ceiling, when each of the plates vibrates, the fan filter unit and the frame are prone to looseness, which causes the fan filter unit and the frame to become loose. Unexpected gaps are formed between them, causing problems such as poor air filtration or backflow of exhaust gas into the clean room.

Therefore, how to get acquainted with the various deficiencies in technology has become a problem that the industry urgently needs to overcome.

In view of the deficiencies of the above-mentioned prior art, the present invention provides a filtering device, which includes: a housing, which is an integrally formed groove-like structure, which has opposite first and second sides and is bounded by the groove-like structure A accommodating space is provided; the filter assembly is arranged on the first side of the housing; the fan assembly is accommodated in the accommodating space and fixed on the second side of the housing; and a guide, It is accommodated in the accommodating space and fixed on the shell.

In the aforementioned filtering device, an opening is formed on the first side of the casing to serve as an outlet port, and the filtering element is allowed to cover the opening.

In the aforementioned filtering device, a perforation is formed on the second side of the casing as an inlet port, and the fan assembly is installed at the perforation.

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

In the aforementioned filtering device, a filter screen is arranged on the second side of the casing corresponding to the position of the fan assembly.

In the aforementioned filtering device, the filtering component includes a filter mesh structure.

In the aforementioned filtering device, the fan assembly includes a fan body, a support member for the fan body to be erected on the casing, and a shaft member pivotally connected to the support member to rotate the fan body.

In the aforementioned filtering device, the guide member is used to cover the cover of the fan assembly.

In the aforementioned filtering device, the guide has a plate body and a retaining wall erected on the side of the plate body, and the retaining wall is formed with a notch to serve as a lead-out port. For example, the top of the retaining wall is bent outward to form a plate, and each plate is formed with a plurality of third fixing holes for bolts to pass through the third fixing hole and the housing of the housing A plurality of fourth fixing holes on the bottom surface of the space fix the guide member to the shell.

The aforementioned filter equipment includes an electronic device for operating the fan assembly, and is arranged inside or outside the casing.

It can be seen from the above that the filter device of this creation mainly uses the shell system to form the shell in an integrated manner, so as to facilitate the formation of a heavy and bulky filter device, and it can avoid the shell when the fan assembly is running. Compared with the conventional technology, this creation can increase the structural strength of the filter device, and can also reduce the vibration and noise problems, and can avoid the looseness between the ceiling frame and the filter device.
