Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.
FIGS. 1 to 7 are schematic structural views showing a preferred embodiment of the present utility model, in which a sand aggregate unpowered dust removal guide chute 100 comprises a guide chute body 101 arranged above a conveying belt 201 of a conveyor apparatus 200, wherein the lower end of the guide chute body 101 is open and faces the conveying belt 201, the lower end of the guide chute body 101 is closed, and a guide chute inlet 101-2 and a guide chute outlet 101-1 are respectively arranged on the front side and the rear side; specifically, a guide chute inlet 101-2 is arranged at the upper part of the front end of the guide chute body 101, and a guide chute outlet 101-1 is arranged at the end part of the rear end of the guide chute body 101;
the guide chute outlet 101-1 is provided with a plurality of layers of wind shielding structures 1011 which are arranged in a staggered manner to form a labyrinth structure, each wind shielding structure 1011 is arranged along the direction of the guide chute outlet 101-1, and a plurality of wind shielding structures 1011 are jointly arranged in the section of the guide chute outlet 101-1.
In specific implementation, the guide chute outlet 101-1 can be provided with three layers of wind shielding structures 1011, each layer of wind shielding structure 1011 is arranged in a staggered way to form a labyrinth structure, dust sedimentation is accelerated, the three layers of wind shielding structures 1011 further optimize trapping effect, sealing performance is better, and dust emission phenomenon is reduced.
In a further alternative implementation of this embodiment, the wind shielding structure 1011 includes a first wind shielding curtain 1011-1 having a saw tooth gap. The passing air flow is disturbed by the sawtooth structure to accelerate dust sedimentation.
In a further alternative embodiment of this embodiment, the first wind shielding curtain 1011-1 is formed by a plurality of vertical strip-shaped adhesive tapes 1011-1-1 side by side, wherein two sides of each vertical strip-shaped adhesive tape 1011-1-1 are provided with saw-tooth shapes, and saw teeth of two adjacent vertical strip-shaped adhesive tapes 1011-1-1 are engaged with each other.
When the gas passes through the sawtooth gap between the vertical strip type adhesive tapes 1011-1-1, the gas is disturbed by the sawtooth structure to flow up and down, so that the mutual collision and sinking of dust are accelerated, and the blocking and capturing effects of the dust are improved. Specifically, the vertical tape 1011-1-1 may be a rubber tape with a width of about 100mm, which is perpendicular to the conveying direction of the conveying belt 201. Each vertical strip type adhesive tape 1011-1-1 is arranged in a mode shown in fig. 3, wherein adhesive tape gaps are staggered to form a labyrinth structure. When the flue gas passes through the gaps of the adhesive tapes, the flue gas is blocked by the second layer of the third layer of the adhesive tapes in a crossing way, and the gas flow speed is rapidly reduced, so that the dust is rapidly settled to prevent the dust from overflowing.
In a further alternative embodiment of the present embodiment, the first curtain 1011-1 is mounted to the chute body 101 by a curtain flange 1011-2. In particular, in order to facilitate replacement of the first curtain 1011-1, a curtain socket may be provided at the top of the curtain flange 1011-2 at a corresponding position, the first curtain 1011-1 is connected to the curtain flange 1011-2 through the curtain socket, and when the first curtain 1011-1 is replaced, the flange is released to take out the first curtain 1011-1 from the curtain socket on the curtain flange 1011-2.

The sedimentation areas 102 arranged on two sides of the guide chute body 101 are less disturbed by the conveying of the conveying materials on the conveying belt 201, and the air is relatively static, so that dust sedimentation can be accelerated.
Compared with the traditional unpowered sealed guide chute settlement structure design at the top, the height of the guide chute is increased, so that some occasions with limitations and requirements on the height cannot be used. In the present embodiment, the dust settling areas 102 are disposed on two sides, so that the height of the designed guide chute body 101 is identical to that of a common guide chute, and the purpose of saving the installation height is achieved.
The dust collecting hopper 1021 can be used for independently collecting and separating the easily-floating dust particles, so that the dust is prevented from being mixed into the air of the next stage of belt conveying and conveying.
When the dust collecting hopper 1021 is too much in dust, the dust can be discharged and collected through the dust cleaning opening 1021-1, so that the secondary dust emission is avoided when the too light dust is always conveyed to a next-stage guide chute along with the material in the material, and the dust suppression pressure of follow-up equipment is reduced.
In a further optional implementation manner of this embodiment, a plurality of air-disturbing structures 1012 are disposed in the guide chute body 101, each of the air-disturbing structures 1012 is disposed at a section of the guide chute body 101, and the plurality of air-disturbing structures 1012 are disposed at intervals along the guide chute body 101.
The air disturbance structure 1012 in which the finished product is arranged inside the guide chute body 101, so that other dust can be shunted to the sedimentation areas 102 on two sides of the guide chute, and the dust shunting is accelerated.
In a further alternative implementation of this embodiment, the air disruption structure 1012 includes an air flow disruption bar 1012-1 mounted to the baffle box body 101 by a disruption bar flange 1012-2. The specific configuration of the disturbance bar flange 1012-2 is identical to that described above and also serves to facilitate replacement of the air flow disturbance bar 1012-1.
The arrangement of the airflow disturbance strips 1012-1 can enable raised dust to enter the sedimentation area 102 as soon as possible, the gas is blocked by the airflow disturbance strips 1012-1 to flow to the sedimentation area 102 on two sides when passing through, and the flow of flue gas in the sedimentation area 102 is far lower than the upper part of the conveying belt 201 in the guide chute body 101, so that the dust in the sedimentation area 102 is naturally settled.
In a further alternative embodiment of the present embodiment, a second weather shield 1013 is provided inside the guide chute inlet 101-2 of the guide chute body 101, and the second weather shield 1013 is disposed at the end section. The second windshield 1013 is configured to further block dust at the inlet of the chute body 101, and the second windshield 1013 may be consistent with the first windshield 1011-1, or may be simply configured as a windshield body, and its specific installation manner may also be implemented by a flange structure, which is specifically configured as above, and will not be described again.
The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the utility model in any way, but any simple modification and equivalent variation of the above embodiment according to the technical spirit of the present utility model falls within the scope of the present utility model.
