The dust extraction system 1300 has a dust exhaust 1351, and the first 1330 or second 1360 dust cover has a dust discharge 1362; in this embodiment, it is preferable that the dust discharge opening 1362 is located on the second dust cover 136, the dust discharge opening 1351 is located above the dust discharge opening 1362 and is communicated with the dust discharge opening 1362 through a vertical pipeline, the dust discharge opening 1362 is located directly above the second belt conveyor 1322, a discharge valve 1352 is connected in series in the pipelines of the dust discharge opening 1351 and the dust discharge opening 1362, the discharge valve 1352 is opened intermittently, the dust discharge opening 1351 is communicated with the dust discharge opening 1362 after being opened, and dust collected in the dust removing apparatus falls down under the action of gravity to fall onto the second belt conveyor 1322, and is then conveyed to the junction 1361 by the second belt conveyor and is discharged from the outlet 13621 at the junction 1361.

It should be noted that in this embodiment, the dust collector 1350 is preferably a pulse bag type dust collector, and the dust hopper of the pulse bag type dust collector can be connected to the dust outlet 1351.

Specifically, in the preferred embodiment, the dust collector 1350 is a pulse bag type dust collector, which is a prior art, dust-containing gas enters the filter chamber from the dust hopper (or the lower part of the dust hopper is opened by a flange), coarse particles directly fall into the dust hopper or the dust bin, the dust gas is filtered by the filter bag, dust is retained on the surface of the filter bag, clean gas enters the air purifying chamber through the bag opening and is discharged into the atmosphere by the fan, when the dust on the surface of the filter bag is continuously increased to cause the resistance of the equipment to rise to a set value, the time relay (or the micro differential pressure controller) outputs a signal, the program control instrument starts to work, the pulse valves are opened one by one to enable compressed air to blow and clean the filter bag through the nozzle, so that the filter bag expands suddenly, under the action of reverse airflow, dust attached to the surface of the filter bag quickly separates from the filter bag and falls into the dust hopper, the dust is discharged by the discharge valve 1352, and after blowing and dust removal of all the filter bags are finished, the dust remover returns to normal operation. The dust removing device has the advantages of strong dust removing capability, high dust removing efficiency, low emission concentration, small air leakage rate, less energy consumption, less steel consumption, small occupied area, stable and reliable operation and good economic benefit.

Further, in order to realize the recycling of the stone powder, a discharge valve 1352 at the bottom of an ash hopper of the pulse bag type dust collector is opened intermittently; after the dust hopper is opened, dust in the dust hopper falls onto a second conveying mechanism 1322 below the dust hopper through the dust discharge port, the dust discharge port and the pipeline under the action of gravity, is conveyed by the second conveying mechanism 1322 and is discharged from an outlet 13621 at a combination point 1361; compared with the method that the dust is conveyed to the stone dust tank through the conveying device or the hoister, the method has the advantages that the original conveying equipment is utilized, the modification workload of the existing equipment is greatly reduced on the basis of realizing dust recycling, new conveying equipment does not need to be added, and the equipment investment and the modification difficulty are reduced; furthermore, the direct fall of the dust to the belt conveyor reduces the problem of increased energy consumption caused by the addition of equipment.

It should be noted that the outlet 13621 at the junction 1361 may be a part of one conveyor line in the feeding mechanism, and one conveyor line may be composed of at least one of the modules, and the conveyor mechanism is communicated with the inlet of another module through the outlet 13621; it may of course also be connected to the communication channel of the switching assembly.

Further, referring to fig. 8, to facilitate installation and maintenance of the belt conveyor, a first dust cover 1330 is removably attached to the belt conveyor 1320 and covers a conveyor belt 13211 of the belt conveyor.

In this embodiment, the first dust cover is U-shaped in cross-section with two linear edges 1332 removably attached to the belt conveyor 1320 by a connector 13213.

Specifically, connecting piece 13213 contains right angle connecting piece 132131 and elastic clamping piece 132132, and connecting plate 132121 extends outwards to the symmetry in frame 13212 both sides of belt conveyor 1320, and a right-angle side of right angle connecting piece 132131 is connected the back with the straight line limit 1332 of first dust cover, and rethread elastic clamping piece 132132 presss from both sides the tight location with connecting plate 132121 with the another side of right angle connecting piece, and such connection structure installation is fixed simple and convenient, and it is convenient to dismantle simultaneously, only need tear off elastic clamping piece 132132 and can dismantle.

Preferably, in order to provide stable and great air current for each dust cover in the whole dust collector, the pipe diameter that sets for the pipeline to be close to the dust collector side in this embodiment is greater than the pipe diameter of distal end, can guarantee like this that each pipeline all has stable and sufficient air current flow at the in-process of removing dust, makes first dust cover and second dust cover can both form good negative pressure and adsorption affinity, promotes dust removal effect.

In addition, it all is located the outermost frame of frame 1000, the dust cage sets up in the outermost frame of frame 1000, water steady material feeding mechanism 100, new temporary storage mechanism 200 that gathers materials, new feeding mechanism 300 that gathers materials all have the shell and form the enclosed state, so the dust is difficult to spill or seldom spill, so with three fixed mounting in the outside of frame 1000, preferably, the dust cage passes through the pipeline and communicates with dust collector 1350, make through dust collector 1350 and form the negative pressure environment in the dust cage, thereby prevent that the dust in the dust cage from outwards waving, the volume and the area of dust cage have been reduced when guaranteeing to reduce the dust diffusion, reduce cost improves dust collector's dust removal effect simultaneously, in addition, do benefit to its equipment package of traditional mix station and improve holistic pleasing to the eye degree.
