Problems solved by technology

[0006] The problems solved by the present invention are: one is that the plate filter used as a pre-filter in the existing industrial filter has a large resistance to the air flow, and the air flow is easy to spread around after passing through, and the turbulent flow is serious; the other is the bag filter. Impurities are easy to accumulate in the filter bag, the service life is low, and it is bulky when used in series as a graded filter

Embodiment 1

[0041] An embodiment of the present invention provides an industrial filter, referring to Figure 4-5 , including a first filter 100, the first filter 100 is a bag filter, including a first support frame 110 ( Figure 4 not shown in the Figure 5 ) and the first filter bag 120 arranged on the first support frame 110, the first support frame 110 is used to support the first filter bag 120, and the first filter bag 120 has a first opening 121.

[0042] Wherein, the quantity of the first filter bag 120 can be set according to the size of the air vent and filtering requirements, Figure 4 5 first filter bags 120 arranged side by side are exemplarily shown, each first filter bag 120 has a first opening 121, there is a gap between adjacent first filter bags 120 and close to the first opening One side of 121 is sealed and connected. In other embodiments, the number of first filter bags can also be other values.

[0043] Such as Figure 5 , the first support frame 110 is a skelet...

Embodiment 2

[0053] The difference between this embodiment and Embodiment 1 is that, referring to Figure 8-9 , the industrial filter of this embodiment also includes a second filter 200 located downstream of the first filter 100 along the air intake direction, that is, the second filter 200 is located on the side of the first filter 100 with the first opening 121, And it is sealed and connected with the first filter 100 through the connecting frame 310 . Specifically, the connection frame 310 includes a first frame 311 connected to a filter 100 and a second frame 312 connected to the second filter 200, the first frame 311 surrounds the air outlet of the first filter 100, and the second frame 312 Surrounds the air inlet of the second filter 200 . The first frame 311 and the second frame 312 are sealed and connected.

[0054] In this embodiment, the first frame 311 and the second frame 312 are connected by buckles 320, and seals 330 are provided between the first frame 311 and the second ...

Abstract

The invention relates to an industrial filter, which comprises a first filter, wherein the first filter is provided with a first filtration bag and a first support frame for supporting the first filtration bag, the first filtration bag is provided with a first bag opening, the outer surface of the first filtration bag is the wind inlet surface of the first filter, the inner surface is the wind outlet surface of the first filter, and the first bag opening is the wind outlet of the first filter. According to the present invention, in the case of the same vent size, the filtration area is increased so as to reduce the gas flow forming resistance; and when the gas flow passes through the first filtration bag, the gas flow passes through the internal space of the first filtration bag and then outflows from the first bag opening, and the wind out gas flow is uniform and stable.

Description

technical field [0001] The invention relates to a filter, in particular to an industrial filter. Background technique [0002] In industrial applications, for factories or workshops that require high air cleanliness, industrial filters with higher filtering effects are required. Such as figure 1 As shown, this industrial filter generally includes a plate filter 1 and a bag filter 2 connected to each other, wherein the plate filter 1 is used as a pre-filter, and the bag filter 2 is used as a fine filter, and the airflow enters along the wind direction W , passing through the plate filter 1 and the bag filter 2 in turn and entering the factory building or workshop. [0003] However, the plate filter 1 as a pre-filter has a relatively large resistance to the formation of airflow, and as figure 2 As shown, when the airflow passes through the plate filter 1 along the wind direction W, the airflow tends to diffuse to the surroundings, and it is difficult to keep stable, and th...
