Embodiment
As shown in Figure 1, a kind of pulp density self-adjusting system, this system is arranged on the ore pulp vent pipe 2 of ore pulp mixing pit 1, and the flow of water-supply-pipe 3 controlling to add water in ore pulp mixing pit 1 is to regulate pulp density, described self-adjusting system comprises the mozzle 4 be communicated with ore pulp vent pipe 2, be arranged on the concentration pot 6 below mozzle 4, for the weighing device 7 of detectable concentration kettle 6 and interior ore pulp weight thereof, be arranged on the liquid level sensor 601 in concentration pot 6 and cpu controller 5, wherein, at ore pulp vent pipe 2, water-supply-pipe 3 and mozzle 4 are respectively arranged with solenoid valve I 201, solenoid valve II 301 and solenoid valve III 401, and the signal controller break-make that these three solenoid valves export by cpu controller 5, the signal that described liquid level sensor 601 detects and weighing device 7 weigh the digital signal obtained and are all input in cpu controller 5 by the data-in port of cpu controller 5, cpu controller 5 is according to the closedown of the signal Controlling solenoid valve III 401 of liquid level sensor 601, the amplitude opened according to the signal Controlling solenoid valve II 301 of weighing device 7 is to regulate the discharge of water-supply-pipe 3.
Described weighing device 7 is electronic balance or pressure transducer.
The control method of above-mentioned pulp density self-adjusting system is as follows:
1) set up the homologous thread of ore pulp weight and pulp density, and by this profile memory in cpu controller, meanwhile, in cpu controller, store standard compliant pulp consistency information;
2) cpu controller sends opening signal to solenoid valve III at regular intervals, to be flow in concentration pot sample to make ore pulp by mozzle;
3), when the mineral syrup liquid in concentration pot touches liquid level sensor, liquid level sensor feeds back to cpu controller stop signal, and cpu controller is closed according to this signal Controlling solenoid valve III;
4) weight information of mortar in the concentration pot detected is fed back to cpu controller by weighing device, the homologous thread of this information with the ore pulp weight stored and pulp density compares by cpu controller, therefrom draw the concentration information of now mortar, and this concentration information and the standard compliant pulp consistency information stored are compared, export three kinds of signals to the solenoid valve II and the solenoid valve I that regulate water-supply-pipe amount of water, solenoid valve II controls the increase of water-supply-pipe flow respectively according to these three kinds of signals, reduce and keep this state, solenoid valve I is held open state or cut out.
In the utility model, the described concrete grammar setting up the homologous thread of ore pulp weight and pulp density is: for the ore pulp of a certain mineral, this ore pulp of concentration known is imported in concentration pot, after in concentration pot, ore pulp reach a certain height, measure its weight, thus obtain under certain volume, the corresponding relation of ore pulp weight and pulp density;
Adopt said method to record the ore pulp quality of ore pulp correspondence under same volume of a series of variable concentrations continuously, then these pulp densities and ore pulp weight are made two-dimensional curve figure, namely obtain weight and the concentration homologous thread of a certain ore pulp;
In practical operation, set suitable time and be stored in cpu controller, coming automatically to sample according to the solenoid valve III controlled this interval time on mozzle in cpu controller.
