Specifically, referring to fig. 1 to 6, a pit dust collecting device includes an exhaust pipe 2 disposed on the bottom and the side wall of a pit 1, the exhaust pipe 2 is communicated with a collecting pipe 3, the collecting pipe 3 is communicated with an air inlet pipe 5 of a bag-type dust collector 4, an exhaust fan 6 is mounted on the collecting pipe 3, a water cooling pipe 7 is sleeved on the outer wall of the air inlet pipe 5, a water cooling cavity 8 is disposed between the inner wall of the water cooling pipe 7 and the outer wall of the air inlet pipe 5, an inlet pipe 9 communicated with the water cooling cavity 8 is disposed at the bottom side of the water cooling pipe 7, an outlet pipe 10 communicated with the water cooling cavity 8 is disposed at the top wall of the water cooling pipe 7, an anti-paste bag filter screen is mounted in the bag-type dust collector 4, the anti-paste bag filter screen includes a filter sleeve 11 connected with the bag-type dust collector 4, a support frame is mounted in the filter sleeve 11, and an electric motor 12 is mounted on the support frame, the rotating end of the electric motor 12 penetrates through the filter sleeve 11 and is provided with a scraping blade 13, and one surface of the scraping blade 13 is attached to the outer wall of the filter sleeve 11.
Thus, high-temperature air containing a large amount of dust in the pit 1 is sucked into the air inlet pipe 5 through the exhaust fan 6, then in the process that high-temperature dust-containing air flow enters the bag-type dust collector 4 through the air inlet pipe 5, the water inlet pipe 9 is communicated with water supply equipment, the water outlet pipe 10 is communicated with drainage equipment, therefore, in the process of continuously supplying water by the water supply equipment, the water cooling cavity 8 is filled with cooling water, so that the cooling water in the water cooling cavity 8 and the high-temperature air flow in the air inlet pipe 5 are utilized to carry out heat exchange, thus, the cooling water is used for cooling the high-temperature dust-containing air flow passing through the air inlet pipe 5, so that the dust-containing air flow can be cooled once in the process of entering the bag-type dust collector 4 through the air inlet pipe 5, thereby effectively avoiding the long-time treatment of high-temperature dust-containing air flow in the bag-type dust collector 4, greatly reducing the service life of the bag-type dust collector 4 and maintaining the frequent condition.
Meanwhile, in the process of using the filter bag, the electric motor 12 is always communicated with an external power supply, the electric motor 12 is enabled to rotate, so that the scraping blade 13 is enabled to rotate by utilizing the rotation of the electric motor 12, the tensioned and tightened filter sleeve 11 can be always attached to the outer wall of the support frame under the action of the support frame and always keeps a positioning state, so that the scraping blade 13 can be in sliding contact with the outer wall of the filter sleeve 11 in the process of performing circumferential rotation around the support frame under the driving of the electric motor 12, the scraping blade 13 is further utilized to scrape and clean the outer wall of the filter sleeve 11, and the materials attached to the outer wall of the filter sleeve 11 are removed by utilizing the external physical action, so that even if the materials attached to the outer wall have certain humidity, the materials can be scraped under the action of the scraping blade 13, and the filter sleeve 11 can be effectively prevented from being stuck in a large area, causing clogging of the filter sock 11. And through external physical action, come to filter sleeve 11 clean in-process, compare in common pulse airflow and clean, its clean effect is better, cleans more easily to the material of sticking with paste the bag.
Further, the support frame includes a plurality of vertical support rings 14, and adjacent two support rings 14 are connected through bracing piece 15, support ring 14 sets up in the filter sleeve 11, filter sleeve 11 is the state of tightening, support ring 14 the outer edge and the outside of bracing piece 15 all with the inner wall contact of filter sleeve 11, one of them support ring 14's inner ring is installed and is used for the installation electric motor 12's installation pole 16, electric motor 12's rotation end down and with support ring 14 coaxial arrangement.
Moreover, there are eight support rods 15, and the support rods 15 surround the axis of the support ring 14, and the distance between two adjacent support rods 15 is the same.
Therefore, the support effect of the support rods 15 on the filter sleeve 11 can be better by using the eight support rods 15 while ensuring the air intake of the filter sleeve 11, and thus, when the scraper 13 rotates to a position between two adjacent support rods 15, the filter sleeve 11 cannot sink into the filter sleeve 11 due to the fact that the distance between the two adjacent support rods 15 is too far, so that the scraper 13 cannot scrape the filter sleeve 11.
Further, a sealing bearing is installed at the bottom end of the filter sleeve 11, and the rotating end of the electric motor 12 penetrates through an inner ring of the sealing bearing and extends out of the filter sleeve 11.
Therefore, by using the sealing bearing, the situation that the rotating end of the electric motor 12 rolls up the filter sleeve 11 to damage the filter sleeve 11 in the rotating process of the electric motor 12 because the rotating end of the electric motor 12 continuously moves relative to the filter sleeve 11 is avoided.
Furthermore, the scraping pieces 13 are installed on the side wall of the electric motor 12, at least two scraping pieces 13 are installed, and the scraping pieces 13 extend towards the air outlet end of the filter sleeve 11 along the outer wall of the filter sleeve 11.
Meanwhile, a polytetrafluoroethylene wedge-shaped scraping block 17 is arranged on one surface of the scraping blade 13 facing the filter sleeve 11.
Utilize polytetrafluoroethylene's wedge like this to scrape piece 17, at doctor-bar 13 pivoted in-process, the material on the surface of filter sleeve 11 is scraped to aforementioned wedge of scraping piece 17 back, and the material is attached to and is scraped on piece 17, simultaneously, because polytetrafluoroethylene's high hydrophobicity, what the material on piece 17 was scraped to the wedge can be very much clears away, and the material is difficult to the adhesion on aforementioned wedge scrapes piece 17.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
