Description
Technical field
A kind of metallurgy sintered detection technique field that the utility model belongs to, and in particular to sintered mixture ventilation
Detection device.
Background technology
Sintering plant obtains mixture after Raw Ore that mining plants ship is mixed, mixture be sintered on pallet after into
For sintering finished material, sintering finished material can produce iron product after being sent into blast furnace.The gas permeability parameter of mixture is in sintering process
In occupy an important position, directly affect the energy consumption of the yield of sintering production, product quality and unit product；Since gas permeability is examined
Parameter is numerous needed for survey, it is difficult to choose suitable test point, be contained mostly with moisture in mixture in sintering production for a long time
Amount carrys out indirect judgement gas permeability, but moisture judgement gas permeability must not be intuitively in mixture.
There is a kind of sintered mixture ventilation detecting system currently on the market, principle is the mixing above pallet
The suitable position of raw material cabin is inserted into a detection pipe, and in raw material cabin external application air blower to detection pipe air blast, and detection blower fan exports
Pressure and flow on pipe, according to flow and the relativeness of pressure, calculate gas permeability.Another kind is patented product《Sintering
Base mix gas permeability off-line detection device》, number of patent application：CN201520387949.1, method are to build one offline
Raw material cabin connects air-introduced machine under raw material cabin, detects pressure on induced duct, flow, and by parameter (the raw material cabin bottom surface of raw material cabin
Product, raw material height) input computer, according to E.W. Wo Yisi formula, calculate the gas permeability of sintered compound raw material.
The first above-mentioned gas permeability detection method is online, needs must have raw material cabin on trolley, and need to set air blast
Machine.Second of gas permeability detection method is offline mode, substantially the experimental provision of E.W. Wo Yisifa, need to set air inducing
Machine, it is impossible to obtain online real time data.
Utility model content
In view of the deficiencies of the prior art, a kind of sintered mixture ventilation detection device of the utility model, simple in structure, behaviour
Facilitate, sintered compound raw material gas permeability can be directly read.
The technical solution of the utility model is：A kind of sintered mixture ventilation detection device, including at least pallet,
1# bellows, radar level gauge, flow transmitter, pressure transmitter, PLC controller and host computer；The 1# bellows are set
It puts below pallet, radar level gauge on the pallet is installed, flow is provided on the 1# wind box branch pipes
Transmitter, pressure transmitter；The radar level gauge, flow transmitter, pressure transmitter are electrically connected with PLC controller；Institute
The PLC controller stated is connect by ethernet output signal with host computer.
Further, E.W. Wo Yisi formula are used in the PLC controller, calculate the gas permeability of trolley mixture.
Further, the device further includes the operator station for being provided with host computer, is read for staff
Sintered compound raw material gas permeability.
Compared with prior art, it is the advantages of the utility model：
1) the utility model uses E.W. Wo Yisi formula, directly detects the pressure on the 1# wind box branch pipes under trolley, flows
Amount, the gas permeability detected is the most direct, draws the extras such as (drum) wind turbine without increasing, and can show that online mixing in real time is former
The gas permeability of material.
2) the utility model is had the characteristics that heat safe using radar level gauge, is suitble to the severe ring at metallurgical operations scene
Border.
Description of the drawings
Fig. 1 is the flow diagram of the utility model device；
In figure：1st, 1# wind box branch pipes；2nd, pallet；3rd, radar level gauge；4th, flow transmitter；5th, pressure transmitter；
6th, PLC controller；7th, operator station.
Specific embodiment
The utility model is further described through with reference to the accompanying drawings of the specification.
As shown in Figure 1, a kind of sintered mixture ventilation detection device, including at least pallet 2,1# bellows, radar
Level-sensing device 3, flow transmitter 5, pressure transmitter 4, PLC controller 6 and host computer.1# bellows are arranged on pallet 2
Lower section, by the use of igniter before on 1# bellows top pallet 2 raw material detect raw material as gas permeability；Because 1# bellows top is burnt
Raw material on knot trolley 2 is mixed raw material that distributing device has just planted, by the use of being used as test point herein the most accurately.
After in pallet 2, igniter, 1# bellows and 1# wind box branch pipes 1, installation is complete, pacify on the trolley on 1# bellows
High temperature resistant radar level gauge 3 is filled, 4~20mA of material thickness signal on the trolley detected is sent to PLC controls by radar level gauge 3
Device 6；Pressure transmitter 4 is installed on 1# wind box branch pipes, pressure transmitter 4 by the 1# wind box branch pipes pressure detected with 4~
20mA is sent to PLC controller 6；Flow transmitter 5 is installed in 1# wind box branch pipes 1, by the flue gas in the 1# wind box branch pipes detected
Flow is sent to PLC controller 6 with 4~20mA, according to above-mentioned detection signal with effective geometric dimension of pallet 2 on 1# bellows
(effective length L, effective width W) applies E.W. Wo Yisi formula in PLC controller 6, calculates the saturating of trolley mixture
Gas, and pass through the host computer that ethernet is uploaded in operator station 7, sintered compound raw material is read by staff and is breathed freely
Property.
More than, the only preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto is appointed
In the technical scope that those familiar with the art discloses in the utility model, the variation that can readily occur in or replace
It changes, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with claim
Subject to the protection domain defined.
