Description
Technical field
The invention belongs to field of metallurgical equipment, particularly a kind of cold rolling levelling unit wet flattening turbulent current real time liquor-mixing system.
Background technology
The wet smooth liquid mixing system of domestic and international existing cold rolling levelling unit all uses two casings to store smooth stoste, deionized water respectively, again two media is transported to the 3rd casing (blending bin) by measuring pump, flow control valve or other form with certain ratio, mix stirring in the 3rd casing, mixed liquid is exported with certain flow from the 3rd casing.The dosing pattern of above system needs three casings at least, disperses on the layout, and floor space is big.It is restricted to adjust smooth liquid proportioning in the actual use, and matched proportion density is subjected to the influence of blending bin input, output liquid, less stable, and adjust inconvenience, adjustment cycle is longer, needs the liquid in the blending bin is removed fully, again from newly carrying out proportioning.Therefore limit the optimum Match of temper rolling technology in formation process.In order to shorten dosing non-cutting time, improve the operating rate of equipment, be provided with this cover liquid mixing system.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can realize the flow of temper rolling technology requirement and the system of concentration accurately, efficiently, automatically and reliably.
Technical scheme of the present invention is, wet flattening turbulent current real time liquor-mixing system, it is characterized in that: comprise two pump control flow closed-loop systems and a turbulent mixture device, pump control flow closed-loop system forms the flow closed loop by the rotating speed of A variable-frequency motor and B variable-frequency motor control A positive displacement pump and B positive displacement pump with A flowmeter and B flowmeter, presets the flow of reserving to reach; The A medium and the B medium of A positive displacement pump and the output of B positive displacement pump are undertaken exporting after the turbulent mixture by the turbulent mixture device.
Described turbulent mixture device adopts multilayer bridge insert Design Mode, two-layer bridge insert by the backing plate clamping between header board and the back plate, between header board and back plate and the backing plate sealing ring is arranged; Header board has two passages, and A medium, B medium enter two-layer bridge insert by two passages, behind the second road bridge insert, by the mixing mouth output of back plate; The length of turbulent flow runner can change with the increase and decrease of the bridge insert number of plies, so that medium can fully mix after entering blender.
Advantage of the present invention is: should consider should have enough flow velocitys in the two media mixed process during design of turbulent mixture device, to guarantee that medium can enter turbulent condition, turbulent process will have sufficiently long runner, and medium could fully mix.The turbulent mixture device is the design of multilayer bridge insert, and the length of turbulent runner can change according to the number of plies of bridge insert to be adjusted.Change three casees liquid storages into two casees liquid storages, apparatus arrangement is simply concentrated, and pump control frequency conversion system increases the reliability of system greatly, prolongs the service life of system.Mix for the 3rd the case and to change real-time turbulent mixture into, set matched proportion density and output flow arbitrarily by computer within a large range, realize wet smooth dosing automation.
Description of drawings
The invention will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the wet flattening turbulent current real time liquor-mixing system schematic diagram;
Fig. 2 is an embodiment of the invention turbulent mixture device structure chart.
Among the figure: 1, header board; 2, back plate; 3, bridge insert; 4, backing plate; 5, sealing ring; 6, A medium; 7, B medium; 8, blending agent; 9, A liquid reserve tank; 10, B liquid reserve tank; 11, A variable-frequency motor; 12, B variable-frequency motor; 13, A flowmeter; 14, B flowmeter; 15, blender; 16, A positive displacement pump; 17, B positive displacement pump.
The specific embodiment
As shown in Figure 1, comprise two pump control flow closed-loop systems and a turbulent mixture device, pump control flow closed-loop system forms the flow closed loop by the rotating speed of A variable-frequency motor 11 and B variable-frequency motor 12 control A positive displacement pumps 16 and B positive displacement pump 17 with A flowmeter 13 and B flowmeter 14, presets the flow of reserving to reach.A variable-frequency motor 11 and B variable-frequency motor 12 carry out Turbulence Mixed synthetic blending agent 8 outputs by A positive displacement pump 16 and 17 outputs of B positive displacement pump by turbulent mixture device 15 with A medium 6 in A liquid reserve tank 9 and the B liquid reserve tank 10 and B medium 7 respectively.Wet flattening turbulent current real time liquor-mixing system, its function is when the cold rolling levelling unit wets smooth mode of operation, proportioning goes out the smooth liquid of certain flow and concentration accurately and efficiently, and the flow of smooth liquid and concentration can be regulated at any time according to the arts demand of smooth unit.
The flow of two systems is by the monitoring of separately flowmeter and shows, supposes that flow separately is respectively Q
1(solute), Q
2(solvent).
The flow that mixes the back medium is: Q=Q
1+ Q
2
The concentration of mixing the back medium is: C=[Q
1/ (Q
1+ Q
2)] * 100%
The input parameter of native system is: C, Q,
Q then
1=CQ Q
2=(1-C) Q
The rotating speed of pump and Q
1, Q
2Form the flow closed loop, dynamically adjust by variable-frequency motor.Therefore, only need on the computer operation picture, to import the value of C and Q, just can adjust the rotating speed of two pumps automatically, satisfy the flow and the concentration of output medium.
As shown in Figure 2, turbulent mixture device 15 adopts multilayer bridge insert 3 Design Modes according to the turbulent property of fluid, two-layer bridge insert 3 by backing plate 4 clampings between header board 1 and the back plate 2, between header board 1 and back plate 2 and the backing plate 4 sealing ring 5 is arranged.Header board 1 has two passages, and A medium 6, B medium 7 enter two-layer bridge insert 3 by two passages, behind the second road bridge insert 3, by the mixing mouth output of back plate 2.The length of turbulent flow runner can change with the increase and decrease of the bridge insert number of plies, can fully mix after medium enters blender 15 guaranteeing.The operator only need import smooth the liquid flow and the concentration of (mixing back medium 8), computer program just can be calculated the flow of each pump needs output automatically according to new flow, densimeter, regulate the rotating speed of pump again by the closed-loop system of flowmeter and pump, thereby reach the flow that new needs are exported, realize presetting the flow and the concentration of smooth liquid.
