Examples

Referring to fig. 1, for the utility model discloses a preliminary dust shaker of pitch dust, including box 1, filter screen 2 and ash bucket 3, be equipped with air inlet 11 along a terminal surface of box 1 horizontal direction, be equipped with gas outlet 12 along another terminal surface of box 1 horizontal direction. The end face of the air inlet 11 is a left end face, and the air inlet 11 is positioned at the position, close to the bottom, of the left end face of the box body 1; the end face of the air outlet 12 is a right end face, and the air outlet 12 is located at a position close to the top of the right end face of the box body 1. The bottom of box 1 is equipped with 3 the same ash hoppers 3, the bottom of ash hopper 3 is inside hollow columniform ash hole 33, the circumference surface of ash hole 33 is equipped with the hand valve 31 that can control ash hopper 3 and open and close, be equipped with glass window 32 on the lateral wall of ash hopper 3, can be clear through glass window 32 see the ash of accumulation in the ash hopper 3, when the dust in the ash hopper 3 accumulates to a certain amount, open hand valve 31 and arrange the ash, close hand valve 31 after the ash discharge is accomplished can.

Referring to fig. 2, a flow guide pipe 13 connected to the air inlet 11 is disposed in the box 1, and the flow guide pipe 13 is inclined upward, so that the airflow blown out from the flow guide pipe 13 is prevented from blowing into the dust hopper 3, which causes dust in the box 1. Filter component 2 from left to right sets up to first filter screen 21, second filter screen 22 and third filter screen 23 in proper order equidistant, and first filter screen 21 is the filter screen of individual layer, and second filter screen 22 and third filter screen 23 are the filter screen of bilayer, and the mesh between the filter screen of bilayer staggers each other, can further improve the filter effect like this. The filter assemblies 2 are all obliquely arranged and face one side of the air inlet 11, so that dust attached to the filter screen can fall into the dust hopper 3 under the action of gravity. The three ash hoppers 3 are respectively arranged below the first filter screen 21, the second filter screen 22 and the third filter screen 23. The meshes of the first filter 21, the second filter 22 and the third filter 23 are sequentially reduced, dust with larger particles is firstly filtered by the first filter 21, and dust with smaller particles can be filtered by the second filter 22 and the third filter 23, so that the particle size of the discharged dust is controlled.

Referring to fig. 2 and 3, the connecting portion of the filter assembly 2 and the inside of the box 1 is provided with a sliding guide rail 4, the sliding guide rail 4 is arranged at the top and the bottom of the box 1, and in combination with fig. 1, the front end face of the box 1 is provided with a plurality of openings 24 corresponding to the position and size of the side face of each filter screen, the side face of the filter assembly 2 contacting with the outside is located in the openings 24, and the side face of the filter assembly 2 and the front end face of the box 1 are in the same plane, one side of the filter assembly 2 facing the outside is provided with a handle 25, the handle 25 is located in the middle of the side face of each filter screen, and the filter screens in the box 1 can be pulled.

The implementation principle of the above embodiment is as follows: drying device is connected to the air inlet 11 of box 1, and the inlet end of sack cleaner is connected to the gas outlet 12 of box 1, and the preliminary dust shaker of pitch dust plays the effect of the great granule of preliminary filtration as connecting in the intermediate apparatus between two equipment. The inside that the dust that the granule size differs got into box 1 from air inlet 11 through honeycomb duct 13, honeycomb duct 13 changes the air inlet direction of dust, blows and beats on first filter screen 21, avoids directly blowing and causes the raise dust in ash bucket 3. The inclined first filter screen 21 filters large dust and causes the intercepted dust to fall into the dust hopper 3; the dust passes through the first filter screen 21 and enters the second filter screen 22, and the second filter screen 22 which is arranged in a double-layer and staggered mode further filters the dust, so that the filtered dust falls into the dust hopper 3; the dust reaches the third filter 23 and is filtered by the third filter 23 having smaller meshes, so that dust having larger particles is more sufficiently filtered. Finally, the dust with smaller particles is discharged out of the air outlet 12, and the preliminary filtration of the dust is completed, so that the size of the dust particles entering the bag-type dust remover is limited, and the bag cleaning period in the bag-type dust remover is prolonged.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
