Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the feeding device for preventing dust explosion of this embodiment can be used for feeding solid raw materials. It comprises a body 1 with a feed channel, a dust collecting tube 2, a dust collector and a grid structure 3. The upper end of main part 1 is equipped with the feed inlet with feedstock channel intercommunication, and the lower extreme of main part 1 is equipped with discharge gate 11 with feedstock channel intercommunication. A dust collecting groove 12 communicated with the feeding passage is provided on a side wall of one end of the main body 1 near the feeding port, and the dust collecting pipe 2 is used for communicating the dust collecting groove 12 and a dust collector (not shown). Grid structure 3 sets up in feedstock channel, and the contained angle between grid structure 3 and the horizontal plane is between 0 ~ 30, and the preferred, feedstock channel in this embodiment can be the straight tubular passageway of vertical setting, and grid structure 3 is preferred perpendicular to feedstock channel, in other words, grid structure 3 is preferred to personally submit 0 contained angle with the horizontal plane.

Borrow by above-mentioned structure, the feed arrangement of this embodiment is equipped with dust collecting tank 12 through near the feed inlet at main part 1 to adopt dust collecting pipe 2 intercommunication dust collecting tank 12 and dust arrester, when having the material to throw in the feed inlet device, the dust of its production can be siphoned away by the dust arrester through dust collecting tank 12 and dust collecting pipe 2, has avoided the loss of dust. And the grid structure 3 arranged in the feeding channel can reduce the descending speed of the powder material to the discharging port 11, is favorable for eliminating static electricity and reduces the risk of dust explosion.

Preferably, as shown in fig. 1, in order to effectively reduce the falling speed of the powder, so as to make the grid structure 3 have better static electricity eliminating effect, the grid structure 3 may be a grid-type grid structure 3, or the grid structure 3 is provided with a plurality of square spaces for the material to pass through. Grid structure 3 can be crisscross by many reinforcing bars and form, and the both ends of each reinforcing bar are connected respectively on the inside wall of main part to when making grid structure 3 play the static elimination effect, also can not excessively influence the speed that the powder descends, thereby the influence throws material efficiency.

Preferably, as shown in fig. 1, the cross-sectional area of the feed channel in the horizontal direction decreases from top to bottom. Specifically, the feeding port of the main body 1 is larger than the discharging port 11 of the main body 1, and the feeding channel tends to decrease in the direction from the feeding port to the discharging port 11. The feed inlet, the discharge outlet 11 and the grating structure 3 may be arranged in parallel, and the vertical distance between the grating structure 3 and the feed inlet may be greater than or equal to the vertical distance between the grating structure 3 and the discharge outlet 11. In other words, grid structure 3 can set up in feed channel's centre or the position that the centre leaned on down along vertical direction, so, can make the powder throw into the back from the feed inlet and just contact with grid structure 3 after being guided to certain position by feed channel, just blockked by grid structure 3 and produce easily and splash when avoiding the powder just throw into from the feed inlet.

Preferably, the feeding device further comprises a cover (not shown) capable of covering the feeding opening, so that when the feeding is completed, the cover is used to cover the feeding opening, thereby further preventing the dust in the feeding passage from escaping outwards.

Preferably, the feeding device of the present embodiment can be made of a steel plate. Further, as shown in fig. 1, the feeding device of the present embodiment may further include an electrostatic grounding device 4 connected to the main body 1, and the electrostatic grounding device 4 may guide static electricity to the ground in time, so as to further reduce the risk of dust explosion.

The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
