The flow-supporting device conveys the gas of the gas source via the annular blowing tube, and injects the gas towards the interior of the bin body at the nozzles, so that a powder material is efficiently prevented from arch connection and shedding in the storage bin, and the powder material can smoothly fall on the rotor scale without an influence on the measuring precision of the rotor scale.
Description
Technical field
The utility model relates to a kind of feed bin that is used for to the blanking of rotor scale.
Background technology
The coal dust that in the production process of cement manufacturing industry and metallurgical system aluminium industry, uses needs continuous and quantitative to add, and coal dust adopts the rotor scale to carry out the weighing metering, delivers to then in the corresponding technological process.Coal dust drops to the rotor scale through the taper feed bin, coal dust under feed bin to rotor scale process, especially under the aqueous ingredients condition with higher, coal dust forms knot arch, canopy storehouse easily in the warehouse of feed bin, cause blanking not smooth, and then have influence on measuring accuracy.
The utility model content
The purpose of the utility model provides a kind of rotor scale that prevents that granular material from connecing arch, canopy storehouse and uses feed bin.
The utility model adopts following technical scheme: a kind of rotor scale is used feed bin; Comprise the taper warehouse; Said warehouse is provided with flow-aiding device; Said flow-aiding device comprises the two-layer above nozzle block that is arranged in successively from top to bottom on the warehouse, and every layer of nozzle block comprises plural spout along the warehouse circumferential directions towards warehouse in-to-in nozzle, and this flow-aiding device also comprises air extractor duct and the ring blowpipe that said nozzle links to each other, admission port is used for to link to each other with source of the gas.
Said ring blowpipe comprise the trunk line that is communicated with source of the gas along warehouse circumferencial direction being used for of extending that is arranged on the warehouse outer wall with link to each other with said trunk line and be arranged on the branch pipe(tube) that links to each other with said nozzle on the warehouse inwall.
Each nozzle in said each layer nozzle block is divided at least one group, all links to each other through a branch pipe(tube) on every group of nozzle, and is respectively equipped with the electromagnetic valve that is used to control this group nozzle break-make on each branch pipe(tube).
Said ring blowpipe is at least one cover arranged from top to bottom that is arranged on the warehouse.
The admission port place of said ring blowpipe is provided with the gas circuit element that is used for filtering gas.
Adopt the feed bin of said structure; Because warehouse is provided with flow-aiding device; This flow-aiding device comprises the multilayer nozzle block of arranging from top to bottom that is arranged on the warehouse, and every layer of nozzle block comprises a plurality of spouts towards warehouse in-to-in nozzle, and each nozzle links to each other with source of the gas through the ring blowpipe that is arranged on the warehouse.This flow-aiding device the gas of source of the gas is carried through the ring blowpipe and at the nozzle place towards the warehouse internal spray; Actv. has prevented that granular material from connecing arch, canopy storehouse in feed bin; Granular material can be dropped on the rotor scale smoothly, be unlikely to influence the measuring accuracy of rotor scale.
In addition; The ring blowpipe of this feed bin flow-aiding device comprises the trunk line that is arranged on the warehouse outer wall and the branch pipe(tube) that is arranged on the warehouse inwall, and each nozzle in every layer of nozzle block is divided into many groups, and every group of nozzle linked to each other by a branch pipe(tube); Also be provided with electromagnetic valve on each branch pipe(tube); Through the solenoid control break-make, make every group of nozzle circulation, alternation, make the maximum fluidisation of coal dust.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the utility model;
Fig. 2 is the branch pipe(tube) assembling scheme drawing of the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of rotor scale of the utility model is with the embodiment of feed bin: comprise up big and down small taper warehouse 1; Warehouse 1 is provided with flow-aiding device; This flow-aiding device comprises 4 layers of nozzle block that are installed in successively from top to bottom on the warehouse 1; Every layer of nozzle block includes the plural spout of evenly arranging along warehouse 1 circumferencial direction towards warehouse 1 in-to-in nozzle 2, because warehouse 1 shrinks from top to bottom gradually, the number of the number of plies of nozzle block and nozzle 2 is according to the actual conditions setting of warehouse 1; In the present embodiment, the number of nozzle 2 is 21, and the number of the nozzle 2 of every layer of nozzle block is respectively 9,6,3,3 from top to bottom.This flow-aiding device also comprises the ring blowpipe 4 that links to each other with each nozzle 2; Each nozzle 2 links to each other with source of the gas through ring blowpipe 4, and this source of the gas uses pressurized air under the general work state; When the CO content overproof in the technology circuit, can select unreactable gas, the switching of source of the gas is through change-over valve control.Towards warehouse 1 internal spray, what can prevent material connects arch, canopy storehouse to the gas that said ring blowpipe 4 provides source of the gas through nozzle 2.
Said ring blowpipe 4 is trunk line 41 and the branch pipe(tube) 42 that links to each other with trunk line 41 along the extension of warehouse 1 circumferencial direction on the outer wall that is arranged on warehouse 1.Trunk line 41 links to each other with source of the gas, the distribution of branch pipe(tube) 42 for ease, two covers of down arranging on said ring blowpipe 4 is served as reasons, uppermost two-layer nozzle block links to each other with leaning on last ring blowpipe, nethermost two-layer nozzle block with by under the ring blowpipe link to each other.Be equipped with the electromagnetic valve 6 that is used to control its break-make on each branch pipe(tube) 42,, can realize nozzle 2 circulations, the alternation of each layer nozzle block, farthest improve the fluidisation of coal dust through electromagnetic valve 6 control break-makes.
In other embodiments, the nozzle 2 of every layer of nozzle block can be divided into some groups, and like every triad, every group of nozzle links to each other through a branch pipe(tube) respectively, and each branch pipe(tube) is provided with the break-make that an electromagnetic valve is used to control cooresponding one group of nozzle 2.
In order to prevent that the gas that blows in the warehouse 1 from containing impurity and moisture, ring blowpipe 4 links to each other with source of the gas through gas circuit element 5, and this gas circuit element 5 is used for filtering gas.
During practical implementation, through control electromagnetic valve 6, the dried compressed air that will pass through 5 filtrations of gas circuit element gets in the warehouses 1 through ring blowpipe 4 and nozzle 2, and nozzle 2 circulates, alternation, prevents that material from connecing arch, canopy storehouse.Connect arch, canopy storehouse phenomenon when relatively serious at material, electromagnetic valve 6 is all opened, and uses the powerful pine of blowing, and 21 nozzles 2 are worked simultaneously.When the CO content overproof, through change-over valve, source of the gas is switched to unreactable gas, to prevent coal dust firing.
