sab 3': the slurry in the slurry return groove B can be pumped by the slurry return pump B, the pumped slurry reaches the circuit breaker for channel selection, and the slurry flows through the slurry return valve A from the circuit breaker and then flows back to the slurry feeding groove A.
The working principle of the technical scheme is as follows: after the slurry is switched to the integrated slurry supply system, the stirring pump of the slurry feeding tank B and the slurry feeding pump of the slurry feeding tank B are closed, so that all slurry supply of the production line B is provided by the slurry feeding tank A, under the integrated slurry supply system, slurry in the slurry feeding tank A is pumped by the slurry feeding pump A and then divided into a path A and a path B for simultaneous slurry supply, the slurry in the path A can be conveyed along a pipeline of a production line A, the slurry in the path B passes through a slurry supply valve and then flows through a slurry supply one-way valve, the slurry supply one-way valve can prevent the slurry in the path B from flowing backwards to the production line A in a manual mode, then the slurry is consumed in the production line B, and the residual slurry can be collected in the slurry returning tank B, pumped out by the slurry returning tank B, conveyed to the variable circuit and reaches the slurry return valve A through the variable circuit, and finally flows back to the slurry feeding tank A to complete supply circulation of the path B.
The beneficial effects of the above technical scheme are that: can prevent during manual switching the thick liquids of B assembly line from flowing backward to the A assembly line through supplying thick liquid check valve, and can not influence the operation of whole A assembly line after switching as an organic whole confession thick liquid system, because the thick liquids consumption of A production line and B production line reduces when the season is poor, so send the thick liquids of dressing trough supply to A to divide partly be used for supplying B production line, thereby can make equipment such as B send the dressing trough to shut down, prevent that the thick liquids supply is surplus to cause the energy waste, can also avoid equipment such as B to send the dressing trough to start repeatedly simultaneously and lead to debugging and break-in time overlength and yields low scheduling problem to appear.
In one embodiment, in the automatic mode, the flow detector controls the pipeline switching to satisfy the following formula
First according to
Q＝μA(2P/ρ)0.5
Wherein Q is the flow rate; mu is a flow coefficient, and is usually between 0.6 and 0.65 related to the shape of the A pulping valve; a is the sectional area of the pipeline; p is the pressure difference before and after passing through the check valve A; rho is the density of the slurry;
measuring the initial flow value Q of the slurry at the one-way valve A when the assembly line A independently supplies the slurry1Then, the flow value Q of the slurry at any moment when the assembly line A independently supplies the slurry is calculated according to the formula of the flow detectori，
Wherein P isiIs the slurry pressure; a. theiIs the cross-sectional area of the slurry flowing through the flow detector; viThe volume of slurry passing through the flow detector at any time; k is the slurry polytropic index, and the elastic modulus of the slurry is negligible;
when the A production line independently supplies the pulp, the flow value of the pulp consumed by the A production line at any moment is
ΔQi＝Q-Qi
Therefore, when the A assembly line independently supplies pulp in the automatic mode, if delta Q < delta QiAnd the flow detector can automatically switch the A assembly line and the B assembly line from the independent slurry supply system to the A assembly line and the B assembly line integrated slurry supply system when the slurry is transported excessively when the A assembly line and the B assembly line independently supply slurry.
The technical proposal is thatThe working principle is as follows: firstly, the rated slurry supply flow Q of the A one-way valve is calculated according to a formula, and then the slurry supply flow Q of the A one-way valve at any moment is measured in the independent slurry supply systemiQ and QiThe difference value is the slurry consumption flow of the A assembly line under the independent slurry supply system and is recorded as delta QiAnd then detecting the flow of the check valve A at any time, and when the real-time consumed flow delta Q is far smaller than the delta QiAt this moment, the number of machines of the A production line is reduced, and the slurry supply system can be automatically switched into an integrated slurry supply system in an automatic mode, so that the equipment utilization rate is increased, and the loss is reduced.
The beneficial effects of the above technical scheme are that: through the design of above-mentioned structure, can judge whether need to change the confession thick liquid system automatically through flow detector for this confession thick liquid system is more individualized more intelligent, has avoided simultaneously supplying thick liquid surplus to cause the energy extravagant, can select whether to transfer back manual mode according to the condition after automatic switch-over, after confirming entering the slack season alright clear up the maintenance with the board to the B assembly line, can only carry out routine maintenance to equipment such as B confession dressing trough earlier when interim order volume reduces.
