[0002] Bag filter dust removal equipment is a very common dust removal equipment in the industrial production process. The bag filter dust collector sends the air containing dust into the bag through the air inlet duct, so that the air containing dust passes through the bag, and the dust therein is filtered by the bag and falls into the ash hopper for collection, and the air after filtration is discharged into the atmosphere.

[0003] Due to the jet flow in the air inlet duct of the dust collector, the air velocity of the air flow flowing into the ash hopper and the bag area is relatively high, which seriously affects the sedimentation of dust particles and the service life of the bag. In view of this technical problem, the bag filter dust removal equipment in the prior art usually adopts a fixed deflector to adjust the direction of the air flow, so as to uniformly diffuse the dust-containing air flow inside the air inlet duct and ensure the dust sedimentation efficiency and the service life of the bag.

[0032] Combined with Figures 1 to 4 As shown, an adjustable deflector device for the air inlet duct of a bag filter is installed in the air inlet duct 1 and includes:

[0033] Two sleeves 2 are longitudinally arranged in parallel on both sides in the length direction of the air inlet duct 1;

[0034] Two arc-shaped slide rails 3 are respectively arranged on the opposite sides of the two sleeves 2. The two arc-shaped slide rails 3 are arranged oppositely, and the arc openings of the two arc-shaped slide rails 3 face upward;

[0035] A deflector 4 is arranged between the two sleeves 2. One end of the deflector 4 is rotatably connected to the opposite sides of the two sleeves 2, and the rotation connection position is above the two arc-shaped slide rails 3. The other end of the deflector 4 is slidably connected to the two arc-shaped slide rails 3; When the actual air flow conditions change, it refers to the change in the air flow rate and the air flow direction. The deflector 4 is used to control the direction of the outflowing air flow and the amount of intercepted air flow to obtain a more flexible flow field adjustment ability;

[0036] A deflection mechanism, connected to the deflector 4, for driving the deflector 4 to deflect;

[0037] A lifting mechanism 6, connected to the two sleeves 2, for driving the two sleeves 2 to move up and down in the air inlet duct 1.

[0038] As an alternative embodiment, the deflection mechanism includes: a cable 5 and a first motor 11. The cable 5 is connected to the deflector 4. The cable 5 passes through the intake duct 1. The first motor 11 is arranged on the outer side wall of the intake duct 1. A winding plate 111 is provided on the rotating shaft of the first motor 11. The cable 5 is wound around the winding plate 111. By providing the first motor 11 with the winding plate 111 on the outer wall of the intake duct, the first motor 11 can precisely control the tightening degree of the cable 5.

[0039] In order to enable the deflector 4 to perform reciprocating up-and-down motion and rotational motion in the intake duct 1, if the angle adjustment of the deflector 4 is directly achieved by using a motor, since the up-and-down position of the deflector 4 is adjustable, it will cause the position of the motor to be uncertain, resulting in the wire moving in the intake duct 1 following the motor. The wire is continuously impacted by the air flow in the intake duct 1 for a long time, presenting a potential safety hazard. Therefore, only the mechanical device transmission of the cable 5 and the first motor 11 in this embodiment can be used to achieve the angle adjustment of the deflector 4.

[0040] As an alternative embodiment, an elastic member 41 connected to the arc-shaped slide rail 3 is provided on the deflector 4. The elastic member 41 is used to provide resistance to the deflection of the deflector 4. Fixed rings 21 are provided on the front side walls of the two sleeves 2. Two fixed rods 31 are provided on the opposite side of the two arc-shaped slide rails 3. Two cables 5 are provided. Both of the two cables 5 bypass the fixed rod 31 on the front side of the deflector 4 and pass through the fixed ring 21 and are combined into a bundle. The two cables 5 together pass through the intake duct 1 and are wound around the winding plate 111.

[0041] As an alternative embodiment, two pairs of fixed bases 7 are provided on the inner wall of the intake duct 1. Each pair of fixed bases 7 is longitudinally distributed. Two sets of lifting mechanisms 6 are provided. One set of lifting mechanism 6 is installed on each pair of fixed bases 7. The lifting mechanism 6 includes: a screw rod 61 and a second motor 62. The screw rod 61 is rotatably connected between the fixed bases 7. The screw rod 7 is rotatably connected to the fixed bases 7 through bearings. The sleeve 2 is threadedly connected to the screw rod 61. The second motor 62 is connected to the screw rod 61.

[0042] As an alternative embodiment, the deflector 4 is arc-shaped. A rotating shaft 42 is rotatably connected to one end of the deflector 4. The rotating shaft 42 is connected between the two sleeves 2. Arc-shaped through grooves are provided on the two arc-shaped slide rails 3. Connecting columns penetrating into the arc-shaped through grooves are provided on both sides of the bottom end of the deflector 4. The arc-shaped through grooves are used to limit the movement of the connecting columns.

[0043] As an alternative embodiment, the winding plate 111 is flush with the through holes of the two cables 5, so as to smoothly pull the cable 5 during the rotation of the winding plate 111, enabling the cable 5 to be smoothly wound around the winding plate 111 without interference from the holes where the cable 5 passes through the intake duct 1.

[0044] As an alternative embodiment, when the pull wire 5 is in a relaxed state, the deflector 4 is deflected to one side of the arc-shaped slide rail 3 under the action of the elastic member 41; the elastic member 41 is a tension spring; the pull wire 5 is used to pull the deflector 4 from one extreme position of the arc-shaped slide rail 3.

[0045] As an alternative embodiment, two elastic members 41 are provided. The elastic members 41 are springs. One ends of the two elastic members 41 are connected to the bottom end of the deflector 4 on the side away from the pull wire, and the other ends are connected to the fixed rod 31. The elastic members are arranged on the fixed rod 31 for easy installation, and there is no need to provide a connection structure for fixing the elastic member 41 on the sleeve 1, making the device structure simpler.

[0046] As an alternative embodiment, a threaded hole is provided inside the sleeve 2. The screw rod 61 passes through the threaded hole, and the screw rod 61 is threadedly connected to the threaded hole. The second motor 62 is arranged at the bottom of the lower fixed base 7. The screw rod 61 passes through the fixed base 7 and is connected to the rotating shaft of the second motor 62.

[0047] The working principle and usage method of this embodiment are as follows:

[0048] The utility model provides an adjustable deflector device for the air inlet duct of a bag filter. When the device is in use, when it is monitored that the air flow rate divided by the deflector 4 in the air inlet duct is small or large, the second motor 62 drives the screw rod 61 to rotate, thereby driving the sleeve 2 to move up and down, so that the deflector 4 is adjusted to a suitable position; when it is monitored that the air flow direction at the deflector 4 is deviated, the winding plate 111 is driven by the first motor 11 to rotate forward and reverse, realizing the contraction and extension of the pull wire 5, thereby changing the inclination angle of the deflector 4, and finally realizing the adjustment and optimization of the flow field.

[0049] The above embodiments are only specific implementation manners of the utility model patent, used to illustrate the technical solutions of the utility model patent, rather than limiting it. The protection scope of the utility model patent is not limited thereto. Although the utility model patent has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: Any person skilled in the art within the technical scope disclosed by the utility model can still modify the technical solutions recorded in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions implemented by the utility model patent, and should all be covered within the protection scope of the utility model.
