[0028] The embodiment of the utility model provides an integrated dust removal and dust conveying device, which utilizes the principle of negative pressure pneumatic conveying to suck out powdered materials on the ground in the coal conveying corridor and in the ash hopper of the dust collector, especially respirable dust from the underground corridor and collects it in the ash bin, which is convenient for centralized treatment and prevents secondary dust pollution.

[0029] Combine the following Figure 1 The technical solution provided by the utility model is described in more detail.

[0030] like Figure 1 As shown, the dust removal and dust conveying integrated device provided by the utility model includes a powder conveying pipeline 1, a dust collector assembly, a driving fan 7, an ash bin 63 and a cleaning assembly 2 for cleaning the ground, wherein: the cleaning assembly 2 is connected to the powder conveying pipeline 1 through a cleaning branch pipe 4, and a first switch valve 3 is provided on the cleaning branch pipe 4, and the first switch valve 3 is used to make the cleaning branch pipe 4 and the powder conveying pipeline 1 conductive or blocked; the driving fan 7 is connected to the powder conveying pipeline 1 and the dust collector assembly, and is used to drive dust into the dust collector assembly, and the ash bin 63 is connected to the settling port of the dust collector assembly.

[0031] The cleaning component 2 can be a cleaning mop in the prior art. The cleaning branch pipe 4 is a hose structure.

[0032] When the first switch valve 3 is opened, the cleaning mop is connected with the cleaning branch pipe 4, the powder conveying pipeline 1 and the dust collector assembly. Under the action of the driving fan 7, the cleaning mop cleans the dust while adsorbing the dust to the powder conveying pipeline 1 and the dust collector assembly through the cleaning branch pipe 4. That is, due to the suction effect of the vacuum negative pressure, the material is sucked into the powder conveying pipeline from the cleaning mop, and the particulate material and dust are collected into the ash bin 63 through the filtering effect of the dust collector assembly. The dust does not return to the production system, thereby reducing the dust concentration of the dust source in the underground corridor and achieving the effect of dust reduction. It can be used for cleaning fine particles and dust on the ground in the coal conveying corridor.

[0033] In the integrated dust removal and dust conveying device of this embodiment, when the first switch valve 3 is closed, the cleaning branch pipe 4 and the powder conveying pipeline 1 are blocked, and the cleaning component 2 cleans the dust on the ground. When the first switch valve 3 is opened, the cleaning branch pipe 4 and the powder conveying pipeline 1 are connected, and the cleaning component 2 cleans the dust on the ground. The dust enters the powder conveying pipeline 1 and the dust collector component in turn under the action of the driving fan 7, and the dust in the dust collector component is processed.

[0034] The integrated dust removal and dust conveying device utilizes the negative pressure pneumatic conveying principle to suck out the powdery materials on the ground in the coal conveying corridor and in the dust collector hopper, especially the respirable dust, from the underground corridor and collect them in the ash bin 63, so as to facilitate centralized treatment and prevent secondary dust pollution.

[0035] As an alternative embodiment, see Figure 1 As shown, there are more than two groups of cleaning components 2 , each group of cleaning components 2 is connected to a corresponding cleaning branch pipe 4 , and all cleaning branch pipes 4 are connected to the powder conveying pipeline 1 .

[0036] See also Figure 1 As shown, multiple cleaning components 2 can clean multiple locations on the ground at the same time, which is beneficial to improve the cleaning efficiency. Specifically, the first switch valve 3 on the cleaning branch pipe 4 can be opened or closed separately, so that the cleaning component 2 has only the cleaning function or the cleaning and dust collection function.

[0037] As an alternative embodiment, see Figure 1 As shown, a first air supply valve 5 is provided at one end of the powder conveying pipeline 1 away from the dust collector assembly.

[0038] When multiple cleaning branches 4 are opened at the same time, opening the first air supply valve 5 is conducive to supplying air to the powder conveying pipeline 1, thereby increasing the gas flow in the powder conveying pipeline 1, so that the airflow can bring dust into the dust collector assembly through the powder conveying pipeline 1.

[0039] As an alternative embodiment, see Figure 1 As shown, the dust collector assembly includes a primary dust collector 61 and a secondary dust collector 62 which are connected to each other, and the dust in the powder conveying pipeline 1 can enter the primary dust collector 61 and the secondary dust collector 62 in sequence.

[0040] The primary dust collector 61 and the secondary dust collector 62 may be dust collectors in the prior art, and their structures are not described in detail again.

[0041] Due to the suction effect of the vacuum negative pressure, the material is sucked into the powder conveying pipeline from the cleaning component 2, and the particulate material and dust are collected in the ash bin 63 through the filtering effect of the first-stage dust collector 61 and the second-stage dust collector 62. The dust no longer returns to the production system, thereby reducing the dust concentration of the dust source in the underground corridor and achieving the effect of dust reduction.

[0042] As an alternative embodiment, see Figure 1 As shown, the air outlet of the dust collector assembly is connected to the first exhaust duct 8, and the exhaust port of the first exhaust duct 8 is provided with a first exhaust hood.

[0043] The particulate matter and dust are collected into the ash bin 63 through filtering action of the primary dust collector 61 and the secondary dust collector 62, and the treated air is discharged through the first exhaust duct 8 and the first exhaust hood, thereby reducing the dust content in the exhaust gas and purifying the air.

[0044] As an alternative embodiment, see Figure 1 As shown, the integrated dust removal and dust conveying device also includes a dust hood 9, a dust collector 11 and an induced draft fan 12, wherein: the dust collector 11 is connected to the dust hood 9, and the induced draft fan 12 is connected to the dust hood 9 and the dust collector 11, and is used to drive the dust in the air or the dust above the equipment into the dust hood 9 and the dust collector 11 in sequence; the dust outlet of the dust collector 11 is connected to the powder conveying pipeline 1, and the dust collector 11 is located in the upstream section of the dust collector assembly.

[0045] See also Figure 1 As shown, the dust collector 11 is connected to the dust hood 9 via a dust suction duct 10 .

[0046] The integrated dust removal and dust conveying device of this embodiment is used for dust removal of production equipment transfer stations, feeders, crushers and other equipment. The dust-containing gas is sucked into the dust suction duct 10 through the dust suction hood 9 under the suction action of the induced draft fan 12, and enters the dust collector 11 through the dust suction duct. Due to the filtering effect of the dust collector 11, the dust is blocked on the outer surface of the filter of the dust collector 11, and the filter cleaning device in the dust collector 11 settles the dust in the ash hopper of the dust collector 11 for temporary storage.

[0047] As an alternative embodiment, see Figure 1 As shown, the dust removal port of the dust collector 11 is connected to a second switch valve 15 and a powder feeder 16, wherein: the second switch valve 15 is located on the pipeline between the dust collector 11 and the powder feeder 16, and is used to connect or block the dust collector 11 and the powder feeder 16, and the discharge port of the powder feeder 16 is connected to the powder conveying pipeline 1.

[0048] When the second switch valve 15 is opened, the dust processed in the dust collector 11 enters the powder feeder 16 and the powder conveying pipeline 1, and then enters the dust collector assembly and the ash bin 63 again under the action of the driving fan 7, and is centrally processed and stored in the ash bin 63.

[0049] As an alternative embodiment, see Figure 1 As shown, the air outlet of the dust collector 11 is connected to the second exhaust duct 13 , and the air outlet of the second exhaust duct 13 is provided with a second exhaust hood 14 .

[0050] The dust gas filtered by the dust collector 11 is discharged to the outside through the second exhaust duct 13 and the second exhaust hood 14, completing the whole dust removal process in the underground corridor.

[0051] As an alternative embodiment, see Figure 1 As shown, a second air supply valve 17 is provided on the powder conveying pipeline 1, and the second air supply valve 17 is located at the upstream section of the powder feeder 16 and at the downstream section of the cleaning branch pipe 4. The powder conveying pipeline 1 is connected with a bypass pipe, and the bypass pipe is located between the powder feeder 16 and the cleaning branch pipe 4, and the second air supply valve 17 is located on the bypass pipe.

[0052] See also Figure 1 As shown, the powder conveying pipeline 1 is connected to a bypass pipe, which is arranged near the powder feeder 16. The second air supply valve 17 is located on the bypass pipe, which is used to increase the gas flow upstream of the powder feeder 16 to prevent the powder from being brought into the dust collector assembly due to insufficient gas flow in the powder conveying pipeline 1.

[0053] The integrated dust removal and dust conveying device of this embodiment, when it is necessary to clean the ground in the underground corridor or to suck the dust in the dust collector hopper, the driving fan 7 and the first switch valve 3 are turned on. When the level meter on the dust collector 11 senses the dust, it sends a signal that the dust in the hopper needs to be cleared, and the device can be started automatically or manually. The second switch valve 15 at the bottom of the dust collector 11 automatically opens, and the powder feeder 16 automatically feeds. The first air supply valve 5 is opened to provide sufficient air volume for the powder conveying pipeline 1 to maintain the wind speed in the pipeline. The second air supply valve 17 on the bypass pipe is opened to provide a high-speed airflow for the acceleration of the dust in the acceleration chamber at the bottom of the powder feeder 16. The high-speed airflow accelerates the dust and forms a dilute phase airflow in the powder conveying pipeline 1. After the dust-containing gas enters the dust collector assembly, it is separated and filtered and then falls into the ash bin 63 for centralized collection.
