[0026] For examples, please refer to Figure 1-3 This utility model provides a technical solution:
[0027] A zirconium corundum abrasive conveying device includes a conveying cylinder 1, a conveying motor 2 installed at the rear of the conveying cylinder 1, a feed inlet 3 and a ventilated screen 4 respectively installed on the outer side of the conveying cylinder 1, a dust suppression mechanism 5 installed at the top of the ventilated screen 4, a drive shaft 6 rotatably installed inside the conveying cylinder 1, and a conveying blade 601 installed on the outer side of the drive shaft 6.
[0028] Specifically, the vertical cross-section of the feed inlet 3 is funnel-shaped, the output end of the conveyor motor 2 passes through the rear surface of the conveyor cylinder 1 and is fixedly connected to the rear end of the drive shaft 6, the conveyor cylinder 1 is a cylindrical structure with an open front end, and the inner diameter of the conveyor cylinder 1 gradually increases from back to front, the conveyor blades 601 are spirally wound around the outer surface of the drive shaft 6, and the outer dimensions of the conveyor blades 601 gradually increase from back to front.
[0029] In this embodiment, the feed inlet 3 is mainly designed to facilitate the entry of zirconium corundum abrasive into the transport cylinder 1. The transport motor 2 is mainly used to drive the drive shaft 6, causing the drive shaft 6 to rotate the transport blade 601. The variable pitch of the transport blade 601 facilitates the transport of abrasive and prevents abrasive accumulation, thus meeting the needs of the user.
[0030] In this embodiment, please refer to Figure 1 and Figure 3 The dust suppression mechanism 5 includes a dust extraction fan 501, a dust suppression box 502, and a water storage tank 503. The dust extraction fan 501 is fixedly installed on the top of the air-permeable screen pipe 4. The top of the dust suppression box 502 is provided with an atomizing nozzle 504. A connecting pipe 505 is fixedly installed on the rear side of the dust suppression box 502. A circulating pump 506 is provided on the top of the water storage tank 503.
[0031] Specifically, the top of the vacuum blower 501 is connected to the interior of the dust suppression box 502 via a duct. The spraying end of the atomizing nozzle 504 extends to the inner wall of the top of the dust suppression box 502. The input end of the circulating pump 506 extends to the bottom of the water storage tank 503 via a pipe, and the output end of the circulating pump 506 is connected to the atomizing nozzle 504 via a pipe. The right side of the connecting pipe 505 is sealed through the front surface of the water storage tank 503 and extends inward. The interior of the connecting pipe 505 is equipped with multiple layers of filter screens with decreasing pore size.
[0032] In this embodiment, the dust extraction fan 501 is mainly used to adsorb and guide the dust generated by the conveyor cylinder 1, causing the dust to enter the dust suppression box 502. The circulating pump 506 is mainly used to extract water from the water storage tank 503 and spray it in an atomized form into the dust suppression box 502 through the atomizing nozzle 504, thereby achieving the settling treatment of dust. The connecting pipe 505 is mainly used to filter the water after dust settling and return it to the water storage tank 503, thus meeting the dust treatment requirements of the device.
[0033] The working process of this utility model is as follows: When using a zirconium alumina abrasive conveying device, the zirconium alumina abrasive is first poured into the conveying cylinder 1 through the feed inlet 3. Then, the conveying motor 2 is started. The output end of the conveying motor 2 drives the transmission shaft 6 to rotate, which in turn drives the conveying blades 601 to rotate. As the variable pitch conveying blades 601 rotate, they propel the abrasive forward. During the movement, the contact space between the abrasive and the inner wall of the conveying cylinder 1 gradually increases, thus preventing the abrasive from being squeezed and accumulated. During the transport process, the dust extraction fan 501 is started, and the dust extraction fan 501 extracts the dust in the transport cylinder 1 through the air vent 4. The dust enters the dust suppression box 502 through the air duct. At this time, the circulating pump 506 extracts water from the water storage tank 503 and sprays it out through the atomizing nozzle 504. The sprayed water mist can coat the dust, and the moist dust settles under the action of gravity. The settled wastewater flows into the water storage tank 503 through the connecting pipe 505 and is filtered by the filter screen, which meets the needs of the users.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
