Specifically, please refer to fig. 1, which illustrates a dustproof discharging device for a belt scale, comprising a vertical feeding pipe 1, wherein the feeding pipe 1 is sequentially communicated with a first bent pipe 2, a second bent pipe 3 and a discharging pipe 4 along a material moving direction, a feeding end of the first bent pipe 2 is vertical, a discharging end of the second bent pipe 3 is vertical and faces downward, and the first bent pipe 2 and the second bent pipe 3 are both pipelines with a radius smaller than a quarter of a circular arc.

Thus, after the materials are conveyed on the belt weigher, the materials fall into the feeding pipe 1 from the discharging end of the belt weigher, then the materials pass through the first bent pipe 2, the second bent pipe 3 and the discharging pipe 4, and finally fall out from the discharging end of the discharging pipe 4, so that in the process that the materials pass through the first bent pipe 2 and the second bent pipe 3, effective buffering can be obtained, namely, the falling speed of the materials can be effectively slowed down in the process of passing through the first bent pipe 2 and the second bent pipe 3, so that when the materials are discharged from the discharging pipe 4, the kinetic energy carried by the materials is lower, a large amount of floating dust generated by the falling of the materials can be effectively reduced, in addition, the first bent pipe 2 and the second bent pipe 3 both adopt pipelines smaller than a quarter circular arc, the horizontal plane can be avoided on the communication surface of the first bent pipe 2 and the second bent pipe 3, and the communication surface of the first bent pipe 2 and the second bent pipe 3 is inclined, and then the effectual material that causes that is avoided piling up and causing the condition of material jam at the horizontal plane that first return bend 2 and second return bend 3 formed because of setting up first return bend 2 and second return bend 3 appears, avoids simultaneously when the material flow diminishes, for example during the tail end of pay-off process, has the material to remain on the intercommunication plane of first return bend 2 and second return bend 3, causes the extravagant condition of material to appear.

Furthermore, the top intercommunication of inlet pipe 1 has the feeder hopper 5 with the belt weigher discharge end intercommunication, the inner wall of inlet pipe 1 is from last to installing first buffer board 6 and the second buffer board 7 that extend of tilt down, first buffer board 6 with the second buffer board 7 is towards opposite direction extension on the horizontal direction.

Utilize the first buffer board 6 and the second buffer board 7 of slope can be further to the material buffering like this, make it slowly get into inlet pipe 1 in, first buffer board 6 and second buffer board 7 can also effectually block the floating dust that the in-process produced of material whereabouts simultaneously, when there is the material in first buffer board 6 top, can effectually avoid floating dust to float out from the mouth of pipe of inlet pipe 1.

Further, first buffer board 6 and second buffer board 7 is not less than at the projection length of horizontal direction inlet pipe 1's radius, and be less than inlet pipe 1's diameter, first buffer board 6 with the bottom of second buffer board 7 with be provided with punishment in advance passageway 8 between the inlet pipe 1 inner wall.

Furthermore, first return bend 2 with the top surface of second return bend 3 covers installs dust cage 9, the top intercommunication of dust cage 9 has exhaust tube 10, exhaust tube 10's the end of giving vent to anger is through flange 11 intercommunication blast pipe 12, the end intercommunication of giving vent to anger of blast pipe 12 has the air extractor, flange 11 mouth of flange 11 covers there is the dust screen, first return bend 2 and second return bend 3 sets up part in the dust cage 9 all sets up to the grid structure.

Like this at the air extractor during operation, the material is at the in-process that falls, the floating dust that produces in first return bend 2 and second return bend 3 and discharging pipe 4 can get into in dust cage 9 through the top surface of first return bend 2 and second return bend 3, the floating dust that can be taken out is by the suction extraction pipe 10 in, and cover on the dust screen, and the floating dust that can not be taken out continues to remain in dust cage 9, when unloading and accomplishing, closed the air extractor after, the dust nature whereabouts in the dust cage 9, it can effectually avoid floating dust to fly away in the air.

Furthermore, the body of the exhaust tube 10 is further communicated with a dust removal tube 13, the body of the dust removal tube 13 horizontally passes through the feed hopper 5, the opening of the dust removal tube 13 faces downward, a sealing valve 14 is installed on the dust removal tube 13, and the outer diameter of the dust removal tube 13 is smaller than the inner diameter of the feed tube 1.

Thus, after the material in the feeding hopper 5 is discharged completely, that is, after the material completely enters the feeding pipe 1, the sealing valve 14 is opened, and under the action of the air pump, the dust removing pipe 13 can extract the upward floating dust generated in the subsequent feeding process, that is, the floating dust generated in the material passing channel 8 after the material above the first buffer plate 6 completely falls behind is prevented from floating upwards and scattering in the environment after the material passing channel 8 between the first buffer plate 6 and the feeding pipe 1 is communicated.

Furthermore, in order to improve the dust collecting effect of the dust removing pipe 13, the air inlet end of the dust removing pipe 13 is communicated with a dust collecting hopper 15 with a downward large caliber, the outer diameter of the bottom end of the dust collecting hopper 15 is smaller than the inner diameter of the feeding pipe 1, and the dust collecting hopper 15 is arranged above the pipe opening of the feeding pipe 1.

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.
