Specific embodiments of the present utility model are further described below with reference to the accompanying drawings.
As shown in fig. 1-4, the automatic medicament deslagging device is characterized by comprising a medicament deslagging box 3 arranged between an inlet of a medicament pump 5 and a medicament storage tank, a deslagging grate 7 arranged in the medicament deslagging box 3, an inlet valve 1, an outlet valve 4, a water inlet valve 2 and a deslagging valve 6 connected with the medicament deslagging box 3, a floating ball switch I9 and a floating ball switch II 10 arranged in a medicament adding tank 8, a low liquid level alarm device connected with the floating ball switch II 10, and a PLC control cabinet connected with each valve, the medicament pump 5 and the low liquid level alarm device.
The utility model relates to an automatic medicament deslagging device, which mainly comprises a medicament deslagging box 3 arranged between an inlet of a medicament pump and a medicament storage tank, wherein a deslagging grate 7, an inlet valve 1, an outlet valve 4, a water inlet valve 2, a deslagging valve 6, a floating ball switch I9, a floating ball switch II 10 and a PLC control cabinet are arranged in a medicament dosing tank 8.
When the medicament pump is not in the dosage, namely the medicament liquid level in the medicament dosing tank 8 reaches the medicament liquid level and the position of the floating ball switch 2, the low liquid level alarm device in the medicament dosing tank 8 acts to remind an operator to check and confirm, and meanwhile, the automatic slag removing device acts and the medicament pump 5 stops: the inlet valve 1 and the outlet valve 4 are closed, the operation of the medicament pump 5 is stopped, the water inlet valve 2 of the deslagging box 3 is opened, and the deslagging valve 6 of the deslagging box 3 is opened; at this time, the deslagging water enters the deslagging box 3, the blocky medicament in the deslagging box 3 is cleared away by the water, after the set time of operation, the water inlet valve 1 of the deslagging box 3 and the deslagging valve 6 of the deslagging box 3 are closed, the outlet valve 4 is opened, the inlet valve 1 is opened, and simultaneously, the motor of the medicament pump 5 starts to operate, and the medicament is conveyed to the medicament adding tank 8 of the flotation platform.
As shown in fig. 3-4: the motor of the medicament pump 5 is controlled by circuit breakers KT1, KT2 and KT3, the KT2 is connected with a power supply KT4 of an alarm in parallel, the KT1 and the KT2 are connected in series, and the KT1, the KT2 and the KT3 are connected in parallel. KT1 is controlled by a float switch I9 in a medicament adding tank 8; KT2 is normally closed and KT4 is normally opened, KT2 and KT4 are simultaneously controlled by a floating ball switch II 10 in a medicament adding tank 8, and KT3 is controlled by a PLC control cabinet; KT3 is closed for 3 minutes and opened for 3 minutes each time, and the signal source of the action instruction of the PLC control cabinet is a floating ball switch II 10.
The power supply parts of the electric heads of the inlet valve 1, the water inlet valve 2, the outlet valve 4 and the slag discharge valve 6 are controlled by two paths at the same time, one path is controlled by the floating ball switch II 10, the other path is controlled by the PLC control cabinet (the control result is opposite to that of the floating ball switch II 10, the program is set to be delayed to be effective for a certain time), the inlet valve 1 and the outlet valve 4 are normally open, and the water inlet valve 2 and the slag discharge valve 6 are normally closed.
When the liquid level in the medicament adding tank 8 is between the starting position of the medicament pump 5 and the stopping position of the medicament pump 5, the inlet valve 1 and the outlet valve 4 are in an open state, the water inlet valve 2 and the slag discharging valve 6 are in a closed state, and the medicament pump 5 works normally;
when the liquid level drops to the medicament pump starting position of the float switch 1, the float switch I9 acts to drive the KT1 to be closed, the medicament pump 5 is powered on to run, the liquid level in the medicament adding tank 8 continuously rises, when the liquid level rises to the medicament pump stopping position of the float switch I9, the float switch I9 acts to drive the KT1 to be disconnected, and the medicament pump 5 is powered off to stop. This is repeated.
When the flow rate of the medicament pump is reduced to a certain degree due to the blockage of an inlet, even if the liquid level is reduced to the starting position of the medicament pump 5 of the float switch I9, the float switch I9 acts to drive the KT1 to be closed, and the medicament pump 5 is electrically operated, but when the medicament consumption in production is larger than the medicament pump flow rate, the liquid level still continuously reduces until the liquid level is reduced to the medicament non-metering position of the float switch II 10 (regarded as the blockage of the medicament slag removal box 3), and the float switch II 10 acts to drive the KT2 to be disconnected and the medicament pump 5 to be stopped; meanwhile, the KT4 is driven to be closed, and the low liquid level alarm device is driven to act to remind an operator of checking and confirming; meanwhile, the automatic slag removing device is driven to act: the outlet valve 4 is closed, the water inlet valve 2 is opened, the inlet valve 1 is closed, and the slag discharge valve 6 is opened; at the moment, the deslagging water enters a deslagging box 3, and the blocky medicament in the deslagging box 3 is cleaned by the water; meanwhile, the control program of the PLC control cabinet is driven to be started:
after reaching the set time delay (such as three minutes of time delay), the water inlet valve 2 and the slag discharge valve 6 are closed, the outlet valve 4 is opened, the inlet valve 1 is opened, and the KT3 is closed (stopped after being closed to the set time) so that the motor of the medicament pump 5 is powered on to start to operate, and the medicament is delivered to the medicament adding tank 8 of the flotation platform. If the action of KT3 is disconnected after the set time (such as three minutes) is reached, if the liquid level rises to exceed the medicine non-metering position of the floating ball switch II 10, the flow rate of the medicine pump 5 is larger than the production medicine consumption speed, the flow rate of the medicine pump 5 is indicated to meet the production requirement, at the moment, the liquid level can enable KT2 to be in a normally closed state, the medicine pump 5 still gets electricity to continue to operate until the liquid level in the medicine adding tank 8 reaches a high liquid level, namely, when the medicine pump 5 is in a stop position, the floating ball switch I9 acts to drive KT1 to be disconnected, and the medicine pump 5 is in a power-off stop operation state to restore to a normal working circulation state.
After the set time (such as three minutes), KT3 action is disconnected, if the liquid level rises and is lower than the medicament non-metering position of the float switch II 10, the flow of the medicament pump 5 still cannot meet the production requirement, at the moment, the liquid level can enable the float switch II 10 to be in an opened state with KT2, the KT4 is driven to be closed, the low liquid level alarm device is driven to act, the automatic slag removing device is driven to act simultaneously, the medicament pump 5 is stopped, and the PLC control cabinet control program is driven to be started simultaneously: and the treatment is circulated until the flow rate of the medicament pump 5 is larger than the consumption speed of the production medicament, and the medicament pump 5 is restored to the normal working circulation state.
According to the automatic medicament deslagging device, manual shutdown and disassembly treatment are not needed for deslagging, the manual deslagging maintenance time is reduced, the service lives of the overflow parts and the mechanical seals of the medicament pump 5 are prolonged, the spare part cost is saved, and the production halt of a ball milling system caused by insufficient medicaments is reduced.
