Abstract
The utility model discloses a raw materials loading attachment is used in production of cerium oxide polishing powder, including the income feed bin that screw feeder and feed inlet upper portion set up, this pan feeding storehouse is fixed at screw feeder upper portion supporting platform through setting up, pan feeding storehouse upper portion outside is fixed with annular negative pressure cover, the through-hole that has a plurality of and annular negative pressure cover intercommunication is opened to pan feeding storehouse upper portion side wall annular, the utility model discloses a set up the annular negative pressure cover that produces the negative pressure on the pan feeding storehouse upper portion of material loading process, the annular negative pressure cover that produces the negative pressure inhales the dust through the through-hole and carries screw feeder in, so both can prevent that the dust diffusion can practice thrift raw materials (cerium carbonate) again, reduction in production cost.
Description
The technical field is as follows:
the utility model relates to a cerium oxide production field, concretely relates to raw materials loading attachment is used in production of cerium oxide polishing powder.
Background art:
the rare earth cerium oxide polishing powder has the advantages of high polishing efficiency, good quality, small pollution and the like in the aspect of polishing precision optical instruments, in the process of producing the rare earth cerium oxide polishing powder, raw materials (cerium carbonate) need to be prepared into the cerium oxide polishing powder through the procedures of feeding, roasting, screening, airflow crushing, sorting, grading and the like, the bagged raw materials (cerium carbonate) need to be hung above a storage bin when the raw materials (cerium carbonate) are fed, the materials are unloaded into the storage bin, then the raw materials enter a screw feeder through the storage bin and are sent into a rotary kiln, but dust of the raw materials (cerium carbonate) diffuses through the upper part when the materials are dumped in the storage bin, the surrounding environment is influenced, and the raw materials (cerium carbonate) are wasted.
The utility model has the following contents:
an object of the utility model is to provide a raw materials loading attachment is used in cerium oxide polishing powder production.
The utility model discloses by following technical scheme implement:
the utility model provides a raw materials loading attachment is used in production of cerium oxide polishing powder, includes the income feed bin that screw feeder and feed inlet upper portion set up, and this income feed bin is fixed at screw feeder upper portion supporting platform through setting up, the income feed bin upper portion outside is fixed with annular negative pressure cover, the through-hole that has a plurality of and annular negative pressure cover intercommunication is opened to pan feeding bin upper portion lateral wall annular, the outside of annular negative pressure cover is passed through the negative pressure adsorption tube and is connected fixedly with the axial fan of installing on the screw feeder lateral wall.
Preferably, a metal net is fixed on the through hole.
Preferably, the mesh number of the metal mesh is 80-120 meshes.
Preferably, the outlet of the axial flow fan is communicated and fixed with the inside of the screw feeder.
Preferably, the negative pressure adsorption pipe is positioned at the upper part of the feeding bin.
The utility model has the advantages that: this practicality sets up the annular negative pressure cover that produces the negative pressure on the pan feeding storehouse upper portion at the material loading process, and the annular negative pressure cover that produces the negative pressure inhales the dust through the through-hole and carries the screw feeder built-in, so both can prevent that the dust from diffusing can save raw materials (cerium carbonate) again, reduction in production manufacturing cost.
Description of the drawings:
in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a perspective view of a portion of fig. 1.
In the figure: the device comprises a screw feeder 1, a feeding bin 2, a supporting platform 3, an annular negative pressure cover 4, a through hole 5, a metal net 6, a negative pressure adsorption pipe 7 and an axial flow fan 8.
The specific implementation mode is as follows:
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 efforts belong to the protection scope of the present invention.
As shown in fig. 1 and fig. 2, the utility model provides the following technical solutions: the utility model provides a raw materials loading attachment is used in production of cerium oxide polishing powder, includes screw feeder 1 and the pan feeding storehouse 2 that feed inlet upper portion set up, this pan feeding storehouse 2 is fixed at 1 upper portion supporting platform 3 of screw feeder through setting up, 2 upper portion outsides in income feed bin are fixed with annular negative pressure hood 4, 2 upper portion lateral wall annular in income feed bin is opened the through-hole 5 that has a plurality of and 4 intercommunications of annular negative pressure hood, the outside of annular negative pressure hood 4 is connected fixedly through negative pressure adsorption tube 7 and axial fan 8 of installing on 1 lateral wall of screw feeder.
And a metal net 6 is fixed on the through hole 5.
The mesh number of the metal net 6 is 80-120 meshes.
And the outlet of the axial flow fan 8 is communicated and fixed with the inside of the screw feeder 1.
The negative pressure adsorption pipe 7 is positioned at the upper part of the feed bin 2.
The utility model discloses a theory of operation and use flow: a travelling crane lifts bagged raw materials (cerium carbonate) above a feeding bin 2, the materials are discharged into the bin 2, and then the raw materials enter a screw feeder 1 through the bin and are conveyed into a rotary kiln;
simultaneously when pouring the material, start axial fan 8, axial fan 8 makes annular negative pressure cover 4 interior production negative pressure through negative pressure adsorption tube 7, and the raw materials (cerium carbonate) dust that produces from pan feeding storehouse 2 like this is when diffusing to pan feeding storehouse 2 outside, produces annular negative pressure cover 4 of negative pressure and inhales the dust through-hole 5 and carry 1 screw feeder in, and metal mesh 6 that sets up at through-hole 5 can prevent that the bold foreign matter from inhaling, so both can prevent that the dust from diffusing can practice thrift raw materials (cerium carbonate), reduction in production cost.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
