Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, the dust removing structure of the crusher of the present invention comprises a dust removing pipeline 1, a settling chamber 2, an air outlet pipe 3 and a door 4.

The dust removing duct 1 includes a first duct 11, a second duct 12, a third duct 13, a fourth duct 14, a first circular arc duct 15, a second circular arc duct 16, and a third circular arc duct 17. One end of the first circular arc pipeline 15 is connected and communicated with the first pipeline 11 by welding, the other end of the first circular arc pipeline is connected and communicated with one end of the second pipeline 12 by welding, namely, the first pipeline 11 and the second pipeline 12 are connected and communicated with each other by the first circular arc pipeline 15, one end of the second circular arc pipeline 16 is connected and communicated with the other end of the second pipeline 12 by welding, the other end of the second circular arc pipeline is connected and communicated with one end of the third pipeline 13 by welding, namely, the second pipeline 12 and the third pipeline 13 are connected and communicated with each other by the second circular arc pipeline 16, one end of the third circular arc pipeline 17 is connected and communicated with the other end of the third pipeline 13 by welding, the other end of the third circular arc pipeline is connected and communicated with one end of the fourth pipeline 14 by welding, namely, the third pipeline 13 and the fourth pipeline 14 are connected and communicated with each other by. To sum up, the first pipeline 11, the second pipeline 12, the third pipeline 13 and the fourth pipeline 14 are connected and communicated in sequence.

The central axis of the first pipeline 11 and the central axis of the second pipeline 12 form a first included angle ≤ α, which is an obtuse angle, and the angle of the first included angle ≤ α is preferably 140 ° to 150 °, and in this embodiment, the angle of the first included angle ≤ α is preferably 144 °. The central axis of the second pipeline 12 and the central axis of the third pipeline 13 form a second included angle ≧ β, which is an acute angle, and the angle of the second included angle ≦ β is preferably between 60 ° and 70 °, and in this embodiment, the angle of the second included angle ≦ β is preferably 66 °. The central axis of the third pipeline 13 and the central axis of the fourth pipeline 14 form a third included angle ° γ, the third included angle ° γ is an obtuse angle, the angle of the third included angle ° γ is preferably between 140 ° and 150 °, and in this embodiment, the angle of the third included angle ° γ is preferably 142 °.

One end of the fourth pipeline 14 is connected and communicated with the settling chamber 2 by welding, one end of the air outlet pipe 3 is fixedly installed on the top of the settling chamber 2 by welding and is communicated with the settling chamber 2, the door 4 is installed on one side of the settling chamber 2 and is used for opening or closing the settling chamber 2, and a sealing strip can be arranged on a door seam of the door 4 to improve the sealing performance of the door. In addition, a separation cover 31 is arranged at the other end of the air outlet pipe 3.

When the invention is used, one end of the air outlet pipe 3, which is provided with the separation cover 31, can be connected and communicated with an external fan through a pipeline, and the dust removal pipeline 1 can face a crusher needing dust removal.

When the dust removal device performs dust removal work, the external fan is started, so that the external fan pumps dust generated by the crusher into the dust removal pipeline 1, and due to the fact that a first included angle alpha exists between the first pipeline 11 and the second pipeline 12 in the dust removal pipeline 1 and a second included angle beta exists between the second pipeline 12 and the third pipeline 13, light and thin crushed materials or garbage mixed in the dust generated by the crusher are difficult to turn due to large self weight, most of the light and thin crushed materials or garbage mixed in the dust can be blocked and fall off after the dust passes through the first included angle alpha and the second included angle beta, and then the dust can also continue to pass through a third included angle gamma which can further block the light and thin crushed materials or garbage which pass through the first included angle alpha and the second included angle beta and can slide down into the settling chamber 2, the main body of the dust is not influenced by all the included angles, so that light and thin broken materials or garbage in the dust can be effectively prevented from accumulating in the dust removing pipeline 1, and the cleaning frequency and the cleaning difficulty of the dust removing pipeline are greatly reduced.

And the dust that enters into in the settling chamber 2 can continue to move toward the direction of air-out pipe 3, and because tuber pipe 3 is located the top of settling chamber 2, then above-mentioned dust can be the U style of calligraphy and flow, and the in-process that flows in settling chamber 4, the large granule dust in the dust can subside to settling chamber 4 bottom, and the tiny particle dust in the dust then can be followed air-out pipe 3 and siphoned away. In addition, the user can access the interior of the settling chamber 4 through the door 4 to clean and maintain the interior of the settling chamber 4.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
