Description
Technical field
The utility model belongs to and selects factory's solid material process field, and particularly a kind of high pressure roller mill is given ore storage bin.
Background technology
Iron ore beneficiating factory in the past all is through three sections fragmentations mostly, and the ore grain size that gets into ore grinding is controlled at 12mm-0, and then through two sections or three sections ore grindings, ore is reached fully dissociate.Ore grinding is because power consumption is big, and the ore grinding power consumption is about 60% of the total power consumption in ore dressing plant.So in the design in current ore dressing plant, will reduce the granularity of finished breaking product as far as possible, reach the purpose that reduces the ore grinding hop count, thereby reduce the ore grinding power consumption, reduce the production cost in ore dressing plant.Existing high-pressure roller mill mainly comprises to ore storage bin; Be arranged on to the material inlet on ore storage bin top be arranged on discharge device to the ore storage bin bottom; Discharge device is a pneumatic gate valve, and does not have the load-bearing pressure inductor to ore storage bin, and pressure inductor is positioned at place, high-pressure roller mill basis; Because it is broken that high pressure roller mill is a pair roller, fragmentation has enough pressure above needing, so need pressure type to give the ore deposit.Existing high pressure roller mill is one highly to be merely 5 meters ore storage bin to ore storage bin, when producing, be easy to generate the not enough phenomenon of material level falling pressure in the storehouse should for ore storage bin, and owing to discharge gate is bigger; Use pneumatic gate valve to need both sides to give gas simultaneously, exist and give gas uneven, gate pushes away inclined to one side phenomenon; Pressure gauge is positioned at high pressure roller mill basis place, the pressure instrumentation be high-pressure roller mill, give ore storage bin; The gross weight of material in the storehouse, the pressure gauge cost increases, and metering is accurate inadequately.
Summary of the invention
The purpose of the utility model provides a kind of safe and reliable, compact conformation, can provide high pressure roller mill required broken static pressure, and the high pressure roller mill that automaticity is high is given ore storage bin.
The purpose of the utility model realizes through following technical proposals:
The high pressure roller mill of the utility model is given ore storage bin; Comprise to ore storage bin, be arranged on material inlet, be arranged on discharge device and control cabinet, it is characterized in that described is inverted trapezoidal structure to ore storage bin to the ore storage bin bottom to ore storage bin top; Describedly be connected on the beam to platform bottom, ore deposit through the load-bearing steelframe to ore storage bin; Pressure inductor one end is welded in on the ore storage bin bulkhead, and the other end is welded on the load-bearing steelframe, and described discharge device is made up of electric gate valve and ore discharge chute; Electric gate valve is connected with giving the ore storage bin feed opening through flange one end; The other end is connected with the suitable for reading of ore discharge chute, and ore discharge chute end opening is connected with the high pressure roller mill material inlet through flange, and described pressure inductor, electric gate valve are connected with the control cabinet of master-control room respectively through being electrically connected.
Described inverted trapezoidal structure give four rib types that ore storage bin is made up of two trapezoidal plates and two rectangles to ore storage bin, it highly is 7 meters.
The utility model the utility model has the advantages that: owing to will have been brought up to 7 meters to the height of ore storage bin; Satisfied the requirement of high pressure roller mill to broken static pressure; Use electric gate valve do not exist gate pushed away inclined to one side maybe, and pressure inductor directly with to ore storage bin links to each other, the pressure that pressure gauge bears is little; Cost is low, and metering is more accurate.
The utility model configuration is reasonable, safe and reliable, compact conformation, can provide high pressure roller mill required broken static pressure, and automaticity is high, it is reliable to operate steadily, maintenance is little, operating rate is high, help ensureing producing and carry out smoothly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the A of the utility model Fig. 1 is to profile.
The specific embodiment
Like Fig. 1, shown in 2, the high pressure roller mill of the utility model is given ore storage bin, and the weighed high pressure roller mill of the utility model is given ore storage bin; Comprise to ore storage bin 1, be arranged on material inlet 2, be arranged on discharge device and control cabinet, it is characterized in that the described ore storage bin 1 of giving is inverted trapezoidal structure to the ore storage bin bottom to ore storage bin 1 top; The described ore storage bin 1 of giving is connected on the framework 5 to ore deposit platform 6 bottoms through load-bearing steelframe 4, and pressure inductor 3 one ends are welded in on the ore storage bin bulkhead, and the other end is welded on the load-bearing steelframe 4; Guaranteed to give the even running of ore storage bin effectively; The pressure that pressure gauge bears is little, and metering is more accurate, and described discharge device is made up of electric gate valve 8 and 9 of ore discharge chutes; Described electric gate valve 8 is connected with giving ore storage bin 1 feed opening through flange 7 one ends; The other end is connected with the suitable for reading of ore discharge chute 9, and ore discharge chute 9 end openings are connected with high pressure roller mill material inlet 10 through flange, and described pressure inductor 3, electric gate valve 8 are connected with the control cabinet of master-control room respectively through being electrically connected.This high pressure roller mill to ore storage bin make full use of control cabinet inner be that the electric control system of core obtains relevant information with the PLC programmable control module; The man-machine interface of console provides various operating functions for the operator, like display screen, control button and audible-visual annunciator.The equipment of having realized is controlled automatically.Because the PLC programmable control module is a prior art, therefore this technology is not described in detail itself.
The described inverted trapezoidal structure of the utility model give four rib types that ore storage bin is made up of two trapezoidal plates and two rectangles to ore storage bin, it highly is 7 meters.Because the utility model will have been brought up to 7 meters to the height of ore storage bin, satisfy the requirement of high pressure roller mill to broken static pressure, use electric gate valve also can not exist gate to be pushed away inclined to one side possibility.When the pressure of pressure inductor 3 induction during less than the required operating pressure of high pressure roller mill, control cabinet sends warning, increases the mine-supplying quantity of giving ore storage bin 1 then, and up to being higher than the required operating pressure of high pressure roller mill, warning stops; During high charge level, control cabinet sends warning, reduces the mine-supplying quantity of giving ore storage bin 1 then in material level that the pressure of pressure inductor 3 induction is amounted to is higher than to ore storage bin 1, and up to the high charge level that is lower than to ore storage bin 1, warning stops.
The setting of the utility model electric gate valve 8 is maintenance of high pressure roller mill for ease, and when high pressure roller mill need overhaul, control cabinet provided instruction; Electric gate valve 8 is closed rapidly, and maintenance finishes, after high pressure roller mill starts; Control cabinet provides instruction, and electric gate valve is opened rapidly.
