The invention will be further elucidated with reference to the drawing.
As shown in fig. 1 or fig. 2, an automatic residual slurry density adjusting device comprises a recovery tank 2 connected with a tubular pile centrifugal pond 1, a metering device, a water storage tank 3, a collecting tank 4 and a controller; the metering device comprises a metering tank 5 with a certain volume and volume scales and an electronic scale 6 positioned below the metering tank 5 and used for measuring the weight of the metering tank 5; a liquid level sensor 7 for monitoring the liquid position is arranged in the metering tank 5; an inlet at the upper part of the metering tank 5 is connected with the recovery tank 2 through a pipeline, a water pump 8 is arranged on the pipeline, and residual slurry is pumped into the metering tank 5 from the recovery tank 2 through the water pump 8; a first electromagnetic valve 9 is arranged at the outlet of the bottom of the metering tank 5 and is connected with the collecting tank 4 through a pipeline; the water storage tank 3 is connected with the collecting tank 4 through a pipeline, and a second electromagnetic valve 10 and a flow meter 11 are arranged at an outlet of the water storage tank 3; the water pump 8, the electronic scale 6, the liquid level sensor 7, the first electromagnetic valve 9, the second electromagnetic valve 10 and the flow meter 11 are connected with the controller.
The liquid level sensor 7 is a common sensor for measuring the liquid level position, and converts the height of the liquid level into an electric signal to be output. In recent years, with the continuous development of electronic technology and automation, liquid level measurement and control technology has been greatly improved. The production of industries such as daily chemicals, food and beverage, medicine and the like can not be kept away from the monitoring of liquid level, the importance of a liquid level sensor is increasingly remarkable, and even the quality of products is directly influenced. The type of the liquid level sensor comprises 1 float ball type liquid level sensor; 2. a float-type liquid level sensor; 3. static pressure type liquid level sensor.
The utility model discloses a theory of operation is: surplus thick liquid that tubular pile centrifugal pond 1 produced is collected and is discharged in collection box 2, surplus thick liquid in the collection box 2 is when saving a quantitative, 8 work of controller control water pump are with surplus thick liquid from collection box 2 carry metering tank 5 in, because the volume of metering tank 5 is certain, and be equipped with level sensor 7 in the certain amount of scale department of volume, when the liquid level that surplus thick liquid was poured into reaches metering tank 5's level sensor 7 position, level sensor 7 signals gives the controller, 6 works of controller control electronic pound, weigh and give the controller with weight signal for metering tank 5. Because the volume of the residual slurry in the metering tank 5 is a constant value, the density of the residual slurry can be calculated only by the weight value of the electronic scale 6, the diluted rated density value is preset in the controller, and the controller calculates the fresh water amount required by the density value of the residual slurry to reach the rated density value. And then controlling a second electromagnetic valve 10 of the water storage tank 3 to be opened and controlling a flow meter 11 to work, injecting a certain amount of clear water into the collecting tank 4, and simultaneously controlling a first electromagnetic valve 9 of the metering tank 5 to be opened by the controller to inject residual slurry into the collecting tank 4, so that the effect of adjusting the density of the residual slurry is achieved, and the residual slurry in the collecting tank 4 is stable in density and can be directly input into a concrete mixer to be used for producing pipe piles or stored for later use.
In the process, the known controller principle and method can be used for the signal transmission modes between the electronic scale 6, the liquid level sensor 7, the first electromagnetic valve 9, the second electromagnetic valve 10, the flowmeter 11 and the controller, and the control mode of the controller, and the controller is preferably a PLC (programmable logic controller) controller because the controller has good stability, is suitable for controlling industrial devices, and can be selected from Siemens and Mitsubishi.
Because the surplus thick liquid in the centrifugal pond 1 can contain a large amount of stones and bulky other impurity, directly arrange into collection box 2 and can influence the work of whole device, so set up filter equipment 12 at the entrance of collection box 2, filter the bulky impurity in the surplus thick liquid, guarantee the stability of follow-up device operation. The filtering device 12 can be a filter screen arranged at the inlet of the recovery tank 2 or a screen roller with helical blades and a water pump of the recovery tank 2 are connected to filter the residual slurry pumped into the centrifugal tank 1.
In order to ensure that the density of the residual slurry entering the metering tank 5 is uniform, a stirring device 13 is arranged in the recovery tank 2 to stir the recovered residual slurry, so that the phenomenon that the residual slurry is stored in the recovery tank 2 for too long to cause sediment deposition to cause that the residual slurry on the upper layer of the recovery tank 2 has more water content, too low density, less water content of the slurry on the lower part and too high density is avoided; the operation of subsequent devices is influenced, for example, the sediment at the bottom is excessive, the residual slurry is thick and is difficult to discharge, and a pipeline is blocked; the residual slurry on the upper layer has high water content and density lower than a preset rated density value, so that subsequent work cannot be carried out. The setting of agitating unit 13 can also avoid surplus thick liquid 2 inner walls of collection box that the deposit caused of stewing to deposit and deposit, alleviates collection box 2's the clearance degree of difficulty. The stirring device 13 is a stirring shaft or a stirring paddle or a helical stirring blade or the like arranged at the bottom of the recovery tank 2, and the stirring device 13 is driven to work by arranging a driving device below the recovery tank 2.
A vibration device 14 is arranged on the outer wall of the metering tank 5 or in the metering tank 5, and the vibration device 14 is selected from the following devices: the vibration device 14 is a vibration motor arranged on the outer wall of the metering tank 5; secondly, the vibrating device 14 is a vibrating rod arranged in the metering tank 5; third, the vibration device 14 is an ultrasonic vibrator provided in the measuring tank 5. Vibrating device 14 works when surplus thick liquid pours into metering tank 5 into, and its main function is the bubble of eliminating in the surplus thick liquid for metering tank 5 measuring surplus thick liquid volume is more accurate, and vibrating device 14 can avoid 5 inner walls of metering tank to deposit incrustation in addition and cause the volume reduction of metering tank 5, alleviates metering tank 5's cleaning work, prolongs metering tank 5's life cycle.
The conveying mode between the metering tank 5 and the collecting tank 4 is that the opening height of the collecting tank 4 is consistent with the bottom height of the metering tank 5, and residual slurry naturally flows into the collecting tank 4 under the action of gravity, as shown in figure 1. In another way, a second water pump 15 is arranged on a pipeline between the metering tank 5 and the collecting tank 4 to pump residual slurry in the metering tank 5 into the collecting tank 4, and the second water pump 15 is connected with the controller, as shown in fig. 2.
A stirring device 13 is arranged in the collecting tank 4, and the stirring device 13 is used for avoiding the phenomenon that the diluted residual slurry is layered due to standing and deposition, so that the density of the diluted residual slurry discharged into a subsequent concrete mixer is not uniform, and the work of the whole residual slurry density automatic adjusting device is meaningless; in addition, the stirring device 13 can also avoid scale deposition on the inner wall of the collecting tank 4 caused by standing and depositing of residual slurry, so that the cleaning difficulty of the recovery tank 2 is reduced, and the service cycle of the collecting tank 4 is prolonged.
