Description

Liquid water automatic measurement system

The present invention relates to a liquid water automatic measurement system commonly used in the chemical industry, textile dyeing industry, and food industry to measure the volume of the liquid.

In general, accurate volumetric measurement of liquids in product production is of great concern as well as the quality of the product produced.

Then, with reference to the accompanying drawings will be described a conventional liquid automatic measurement system.

1 shows a liquid automatic measurement system according to the prior art. The system has a plurality of storage tanks (10). Each storage tank 10 has a magnetic mixing element 101 on its inner bottom surface. The magnetic plate 103 is disposed below each storage tank 10 and is rotated by the motor 102. When the motor 102 is driven, the magnetic plate 103 is rotated on the axis, thereby causing the magnetic mixing element 101 to stir and mix the liquid in each storage tank 10. Each storage tank 10 further has a control valve 105 and a supply pipe 104 installed on the upper surface. The liquid is drawn out of each of the storage tanks 10 by the suction pipe via the supply pipe 104 and directed toward the container 107 on the upper surface of the electronic balance 106, and thus is measured. When liquid is supplied in the container 107 by the desired volume, the weight signal of the electronic mirror 106 is transmitted to the control circuit of the microprocessor 108, thereby causing the control valve 105 to lock.

However, while the conventional liquid measuring system having such a configuration has an advantage of being suitable for use in measuring a liquid having a low viscosity, in order to have a large measuring performance, a large number of storage tanks and supply pipes can be used. There was a problem to be provided. In addition, another problem of the automatic measurement system of this type of liquid is that the remaining liquid in each supply pipe cannot flow back to each storage tank and is retained in each supply pipe, thereby remaining continuously. Therefore, a measurement error tends to occur with a long time use of the measurement system. This liquid residual problem becomes more serious when the storage tank is used to receive high viscosity liquids. Therefore, the present invention has been devised to solve such a problem, and its purpose is to consist of a simple configuration device that accurately and simply measures such a liquid even when the atmospheric pressure exceeds the internal pressure of each storage tank or the viscosity of the liquid is high. It is to provide an automatic measurement system for the liquid.

One lead wire 324 of the isolation cell 328 having the configured valve port 321, the electromagnetic valve 322 mounted inside the isolation cell 328, and the winding 323 of the electromagnetic valve 322 disposed close to the valve port. ) And a ring electrode 327 disposed outside the isolation cell 328 and connected to the other lead wire 325 of the winding 323 of the electromagnetic valve 322. The pulley block system 4 has a track 42 disposed transversely parallel to the main axis 1, a carriage 41 moving along the track 42, mounted on the carriage 41 on one side and moving up and down. Is mounted on the platform 43 by a hydraulic or inertial drive and the upper surface is moved horizontally mounted on the platform 43 controlled by the control interface (7), and horizontally mounted on the platform to be moved to A horizontal slide 44 is provided. The horizontal slide 44 includes a first electrode 441 and a second electrode 442 configured to contact the plate electrode 326 and the ring electrode 327 of each distribution control device 32 of the storage tank 3. Equipped. Each distribution control device 32 when the first electrode 441 and the second electrode 442 of the horizontal slide 44 is moved to contact the plate electrode 326 and the ring electrode 327 of the distribution control device 32. ) Electromagnetic valve 322 is started to open the valve port 321. On the contrary, when the first electrode 441 and the second electrode 442 are spaced apart from the plate electrode 326 and the ring electrode 327 of the distribution control device 32 and move with the horizontal slide 44, respective distributions are performed. The electromagnetic valve 322 of the control device 32 is stopped and the valve port 321 is shielded. The first electrode 441 and the second electrode 442 are each made of a highly conductive elastic metal.

FIG. 6 shows another embodiment of the present invention, in which the hooks 23 of the paired rotary wheels 2 are made of a highly conductive metal, and the bent ends 231 of the hook are grounded. The ring electrode 327 of the distribution control device 323 of the corresponding storage tank 3 is uniformly supported to form a terminal, and the second electrode 442 of the horizontal slide 44 mentioned above is omitted. does not exist. When the first electrode 441 of the horizontal slide 44 is moved to be in contact with the plate electrode 326, the valve port 321 is opened.

4 and 5, since the distribution control device 32 of each storage tank 3 has only one valve port 321, the atmospheric pressure exceeds the internal pressure of each storage tank 3, or Alternatively, when the viscosity of the liquid is high, the liquid cannot be smoothly discharged out of each storage tank (3). In order to solve this problem, a high pressure air supply system 9 is installed. The high pressure air supply system 9 has a high pressure air pipe 91 inserted through the horizontal slide 44. The high pressure air pipe 91 has a funnel-shaped coupling 92 at one end for connecting to the valve port 321, and a control valve 93 at the other end connected to the high pressure air source, thereby providing air and The inert gas can be supplied without reacting with the liquid in the corresponding storage tank 3.

As shown in FIG. 7, the high pressure air supply system 9 is installed in front of the rotary wheel 2, and the distribution control device of the storage tank 3 in which the coupling 92 of the funnel is moved upward. 32 may be moved horizontally and vertically to attach to the valve port 321.

When one storage tank 3 is filled with compressed air, the valve port 321 of each distribution control device 32 is closed, and each storage tank 3 is moved to the bottom surface, and the valve port 321 is moved. Is opened again, so that the liquid is quickly discharged out of each storage tank (3) to the container (6) on the top of the electronic balance (5).

When the liquid is to be discharged out of one storage container 3, as shown in Figs. 4 and 7, the high pressure air pipe 91 of the high pressure air supply system 9 connects the coupling 92 to the valve port 321. Is moved horizontally and vertically to mate with and pressurizes the control valve (93). Then, the control valve (93) is pushed into the storage tank (3) through the high pressure air pipe (91), the coupling (92) and the valve port (321). Open to be applied. When the internal pressure of the storage tank 3 exceeds the atmospheric pressure, as also shown in Fig. 5, the high pressure air pipe 91 is restored to its original position, and the liquid in the storage container 3 is directed to the lower valve port 321. At the same time the platform 43 and the horizontal slide 44 pressurize the first electrode 441 and the second electrode 442 to contact the plate electrode 326 and the ring electrode 327, respectively. The valve port 321 is opened and relatively moved so that the liquid can be discharged from the storage tank 3 toward the container 6. In another embodiment of the present invention as shown in Figure 6, the ring contact surface 327 is disposed in contact with the hooks 231, the electrode 441 is pressed to contact the plate contact surface 326, the liquid The valve port 321 is opened to be discharged from the storage tank 3 toward the container 6.

The aforementioned electronic mirror 5 is mounted on the carriage 41 to measure the weight of the liquid carried into the container 6. When the increase in the amount of liquid in the vessel 6 reaches a predetermined value, the control interface 7 immediately signals the microprocessor 8 to move to the horizontal slide 44 and thus the horizontal slide ( Electrodes 421 and 422 of 44 are respectively shorted from the plate electrode 326 and the ring electrode 327 to stop the operation of the electromagnetic valve 322 and close the valve port 321.

The above-mentioned container 6 is a storage container with a ceiling opened on the electronic balance 5 to receive the liquid discharged from one storage tank 3.

The aforementioned control interface 7 receives signals from the pulley block system 4, the electronic balance 5 and the high pressure air supply system 9; Supply the received signals to the microprocessor 8 for processing; The microprocessor 8 drives the pulley block system 4, the high pressure air supply system 9, the platform 43 and the horizontal slide 44, and the electromagnetic valves in the distribution control device 32 of each storage tank 3. The control valve 93 of the high pressure air supply system 9 depends on the operation of the 322, the operation of the power drive driving the main shaft 1, and the input data and signals of the electronic balance passing through the control interface 7. ) To control the operation.

The main shaft 1 is rotated at a low rotational speed when no liquids are to be supplied. When the main shaft 1 is rotated, the storage tank 3 moves together with the rotary wheels 2, whereby the respective liquids are mixed in the respective storage tanks 3. When supplying liquids, the microprocessor 8 issues a command to the power drive via the control interface 7, thereby driving the spindle 1 in clockwise direction in response to the detection of the position sensing device in the spindle 1. Or counterclockwise rotation, thereby allowing the storage tank 3 containing the selected material to be moved from the bottom to the discharge position. At the same time, the microprocessor 8 provides a signal to the pulley block system 4 via the control interface 7, whereby the carriage 41 is arranged perpendicularly to the discharge position of the selected storage tank 3. The flat electrode 442 of the distribution control device 32 of the storage tank 3 to be moved along the track 42 and the first electrode 441 and the second electrode 442 of the horizontal slide 44 are selected. And the horizontal slide 44 is moved toward the position where it is pressurized to contact the ring electrode 327, thereby causing the valve port 321 to open.

When the valve port 321 is opened, the coupling 92 of the high pressure air pipe 91 of the high pressure air supply system 9 is engaged with the valve port 321 and the high pressure air is selected. To be applied When the internal pressure of the selected storage tank 3 exceeds the atmospheric pressure, the high pressure air pipe 91 of the high pressure air supply system 9 is in situ to detach the coupling 92 from the valve port 321, and thus the selected liquid. Water flows out of the storage tank 3 to the container 6 through the valve port 321. When the weight of the liquid in the container 6 reaches a reference value, the electronic balance 5 immediately signals the microprocessor 8 via the control interface 7, whereby the microprocessor 8 selects the selected material. Instruct them to stop their supply.
