First motor-driven valve 2, first manual valve 1；The first manual valve 1 is in normally open, is used for and first motor-driven valve
2, the pipeline pump 3, which cooperates to the first slurry tank 16, is added stirring liquid 15 used.
In addition, the first slurry tank 16 also includes feeding inlet (not shown in figure 1), the original of slurries can be added from feeding inlet
Material.
The bottom of first slurry tank 16 has an independent first outlet pipeline 22 to coke oven coal charging car dress slurry of N root, and every the
Second motor-driven valve 6 is installed on one outlet conduit 22 and fills slurry automatically for realizing pouring sizing device automatically to coke oven coal charging car, N is greater than etc.
It in 1, and is integer.
Be above coal tower automatically and sizing device specific structure, be described below coal tower automatically and sizing device implementation
Journey.
Coal tower is automatic and sizing device is during progress and slurry, and the first blender of electric control system controls 4 is to the first slurry tank
Mixture in 16 is stirred and starches.In addition, the implementation process is there are two first liquid level gauge 5 with setting on the first slurry tank 16
Example.
The first liquid level gauge 5 in low liquid level monitors that the slurries in the first slurry tank 16 are in low liquid level on first slurry tank 16
When, the first obtained monitor value can be sent to electric-control system, electric-control system is based on the first control of first monitor value generation and refers to
It enables, and starting pipeline pump 3 is controlled according to first control instruction, and control and open the first motor-driven valve 2, to the first slurry 16 liquid feeding of tank
Body 15.
The first liquid level gauge 5 in high liquid level monitors that the slurries in the first slurry tank 16 are in height on the first slurry tank 16
When liquid level, the second obtained monitor value can be sent to electric-control system, electric-control system is based on second monitor value and generates the second control
System instruction, and according to second control instruction control pipeline pump 3 be automatically stopped, and control close the first motor-driven valve 2, with stop to
Liquid feeding body 15 in first slurry tank 16.In addition, sealing material, starting blender stirring, shape is added in electric control system controls in slurry tank
At uniform sealing slurry.
In addition, the second slurry tank 17 that the first slurry tank 16 and coke oven coal charging car pour sizing device automatically passes through first outlet pipeline 22
Connection, and dress slurry is carried out to the second slurry tank 17 by the slurry mouth 7 that connects in the second slurry tank 17 by the control of the second motor-driven valve 6.
Fig. 2 is please referred to, is that a kind of coke oven coal-charging disclosed by the invention pours the coke oven coal charging car of slurry system automatically and pours slurry automatically
The structural schematic diagram of device.
Coke oven coal charging car pours sizing device automatically, is mounted on coke oven coal charging car, comprising: electric-control system (and coal tower automatically and
Electric-control system in sizing device is same), N number of that there is the second slurry tank 17 for connecing slurry mouth 7, be arranged on each second slurry tank 17
Two blenders 8, blowback solenoid valve 13, Pneumatic butterfly valve, the second hand-operated valve 10, second liquid level gauge 9.N is more than or equal to 1, and is integer.
In general, electric-control system uses PLC control system.Wherein, the second hand-operated valve 10 is in normally open, can be used for
Maintenance.
Specifically, coke oven coal charging car every time can coaling to 4 holes of coalingging, and pour sizing device automatically and each pour slurry tank again
Two-way pipeline is divided to be sealed charging hole lid 19.When charging car installs coal, and after covering bell, the pneumatic of sizing device is poured automatically
Butterfly valve is successively opened, and by electric control system controls complete to pour slurry movement and control slurries number sufficiently ensure the effect of sealing
Fruit.
The specific structure of each component is described below.
For each second slurry tank 17:
It is fitted with the second blender 8 on each second slurry tank 17, for stirring the slurries in each second slurry tank 17
It mixes, it can be seen that.The present invention before filling, has been actually passed and has been stirred twice, and then slurries can be made more uniform, energy
Enough further avoid the problem poorly sealed due to the uneven bring of slurries.
The side installation of the second slurry tank 17 is for starching the second liquid level gauge 9 of tank high liquid level, low liquid level monitoring.
High liquid level, the low liquid level of second slurry tank 17 can respectively be equipped with second liquid level gauge 9, realize the prison of liquid level respectively
It surveys.High liquid level, the low liquid level of second slurry tank 17 can certainly all be monitored using the same second liquid level gauge 9.Second liquid level
Monitor value is transferred to electric-control system by meter 9, pours the reference data for taking slurry, dress slurry of sizing device automatically as coke oven coal charging car.
Each second slurry tank 17 can respectively connect second outlet pipeline 23, and second outlet pipeline 23 is used for coke oven coal-charging hole
Port lid and hole seat 18 between gap carry out pouring slurry.
On the second outlet pipeline 23, it is sequentially connected the second hand-operated valve 10, the first Pneumatic butterfly valve 11, the second pneumatic butterfly
Valve 12 pours slurry for realizing from the corresponding coke oven road coal port 20 of trend.
In the specific implementation process, can be connected with shotcrete pipe 21 with second outlet pipeline 23, for slurries from
Second outlet pipeline 23 flows into shotcrete pipe 21, and the gap then flowed between charging hole lid 19 and hole seat 18 is blocked.
In addition, the blowback solenoid valve 13 is additionally provided on the second outlet pipeline 23, the blowback solenoid valve 13
One end is arranged between first Pneumatic butterfly valve 11 and second Pneumatic butterfly valve 12, the other end of the blowback solenoid valve 13
It is connect with 14 pipeline of compressed air, is used for outlet conduit anti-clogging blowback；
Second hand-operated valve 10, between first Pneumatic butterfly valve 11 and the second outlet pipeline 23；Described
On the second outlet pipeline 23 that two slurry tanks 17 can be connected respectively, it is sequentially connected the second hand-operated valve 10, the first Pneumatic butterfly valve 11, second
