That is, the protrusion is provided between the filter unit supporting part 51 and the first filter part 31 to partition the filter unit supporting part 51 and the first filter part 31, so that the receiving space 7 is configured by the filter net fixing frame 312, the second filter part supporting frame 313, the protrusion 6, and the filter unit supporting part 51 as walls.
In the present embodiment, as shown in fig. 2 to 3, the frame 1 includes a spot check port 11 and a spot check panel 12. The spot inspection port 11 is an opening provided to facilitate spot inspection of the filter unit 3, and the opening is at least sized to allow the filter unit 3 to be taken out from the spot inspection port 11. The spot inspection panel 12 is used to cover the spot inspection port 11.
The above is a description of the configuration of the air cleaning apparatus according to the embodiment of the present invention.
The operation and installation of the air cleaning device according to the embodiment of the present invention will be described.
In this embodiment, the air entering the frame 1 from the air inlet 2 first enters the first filter unit 31, the dust particles with large volume in the air are filtered by the first filter unit 31, then the air enters the second filter unit 32, the dust particles with small volume in the second filter unit 32 are also filtered, the filtered clean air is blown to the air supply unit 8 from the air outlet 511, and finally the air is discharged from the air outlet 4.
Before the filter unit 3 is installed, the movable part 521 of the locking assembly 52 is moved away from the filter unit supporting part 51 until the space between the movable part 521 and the filter unit supporting part 51 is larger than the space required for installing the filter unit 3, and then the filter unit 3 is inserted, because there is enough space for the filter unit 3 to be inserted, the filter unit will not generate friction with the movable part or the filter unit supporting part, and the sealing performance is ensured.
When the filter unit 3 is attached, the filter unit 3 can be inserted into the inside of the frame 1 along the guide of the V-shaped guide rail of the movable portion 521. Since one end of the movable portion 521 is fixed to the filter unit support portion 51, the distal end portion of the filter unit 3 inserted into the frame 1 is automatically pressed between the movable portion 521 and the filter unit support portion 51 and fixed.
When the tip end portion of the filter unit 3 is fixed, the bolt 5221 is rotated, and the movable portion 521 is pushed by a pushing force in the direction of the filter unit 3 to move the movable portion 521. When the movable portion 521 moves to contact with the filter unit 3, the filter unit 3 is driven to move toward the filter unit support portion 51, and during the movement, the stopper piece 53 penetrates the insertion hole 5214 of the movable portion 521, thereby restricting the movement of the movable portion 521 in the direction perpendicular to the movement direction of the movable portion 521. That is, in the air cleaning device mounted state, the movement of the movable portion 521 in the up-down direction is restricted. The movable portion 521 is ensured not to deviate from the movement track in the process of moving. Thereby ensuring airtightness.
When the first filter part 31 of the filter unit 3 abuts against the projection 6 provided on the filter unit support part 51, the bolt 5221 cannot be rotated any more, and the filter unit 3 is tightly fixed to the filter unit support part 51. Thus, the installation is simple and convenient, and the airtightness between the filter unit 3 and the filter unit support part 51 is ensured without using a sealing cotton, thereby suppressing the decrease of the filtering effect due to the air leakage and reducing the cost.
In addition, since the air cleaning device includes the protrusion 6 having one end connected to the filter unit supporting part 51 and the other end connected to the first filter part 31, the protrusion 6 is integrally formed with the filter unit supporting part 51 in this embodiment. That is, the protrusion 6 is disposed between the filter unit supporting part 51 and the first filter part 31 to partition the filter unit supporting part 51 and the first filter part 31 such that a receiving space 7 capable of receiving the second filter part 32 is formed therebetween. When the user increases or decreases the number of the second filter parts 32 as required, since the upstream side of the first filter part 31 is locked by the locking assembly 52 and the downstream side presses the protrusion 6, the first filter part 31 is not displaced by the attachment and detachment of the second filter part 32, and the housing space 7 is not lost by the decrease of the second filter part 32, thereby achieving the effect of ensuring airtightness even if the number of the filter parts is adjusted.
When the user needs to remove the entire filter unit 3, first, the bolt 5221 is rotated in the direction opposite to the mounting direction so that the movable portion 521 no longer presses the filter unit 3, and then, the filter unit 3 can be removed by moving the movable portion 521 in the direction away from the filter unit 3. In addition, because be equipped with second filter house support frame 313 on the first filter house 31, when needing to take out the filter unit 3 from some inspection mouth 11 and examine the time, through the bearing of second filter house support frame 313, just can take out second filter house 32 and first filter house 31 from some inspection mouth 11 simultaneously, that is to say, when examining filter unit 3, the personnel of examining need not take out second filter house 32, first filter house 31 respectively, can take out the point with whole filter unit 3 simultaneously and examine, make the operation more convenient, simple.
Further, by providing the air guide surface 5111 inclined to the downstream side from the outer peripheral side to the inner peripheral side of the air outlet 511 at the air outlet 511, the wind energy is more intensively and smoothly blown to the air blowing unit 8 provided on the downstream side of the filter unit support portion 51, thereby reducing the occurrence of turbulence and increasing the air volume.
In this embodiment, the second filter support frame 313 may not be provided, and the receiving space 7 may be formed by providing the protrusion 6 in the first filter portion 31, extending from the filter holder 312 to the filter unit support portion 51, or protruding from the upper or lower portion of the filter unit support portion 51 toward the first filter portion 31 until extending over the filter holder 312; that is, the housing space 7 is formed by walls of the filter screen holder 312, the projection 6, and the filter unit support portion 51. The above-described effect is the same as the above-described effect when the second filter support frame 313 is provided.
