Description
Technical Field
The utility model relates to the field of liquid level measurement, in particular to an electrolytic cell liquid level measurement device for preparing corrosive gas by an electrolytic method.
Background
When the electrolytic method is adopted to prepare corrosive gas, the liquid level of the electrolytic cell needs to be monitored so as to facilitate the normal operation of production. The electrolytic cell is a device for storing and reacting electrolyte in an electrolytic workshop, and the production process is influenced by too high or too low liquid level in the electrolytic cell. For corrosive liquid to be measured, a non-contact liquid level meter (ultrasonic wave or radar) and a contact liquid level meter (floating ball type or capacitance type) are generally adopted. The non-contact liquid level meter is applied more, the measurement result is more accurate, but the installation cost is higher; in the contact type liquid level meter, the floating ball type liquid level meter has poor corrosion resistance effect and is easy to malfunction in a use environment with particles or possibly generating crystals; the capacitive liquid level meter is easy to have the phenomenon of hanging materials when the electrolyte is viscous, the measurement accuracy is influenced, and the probe needs anti-corrosion treatment, so that the cost is increased. Therefore, the problem of how to more accurately monitor the liquid level of corrosive and certain viscous medium in the electrolytic cell in real time and reduce the cost needs to be solved urgently.
SUMMERY OF THE UTILITY MODEL
In view of the problems in the prior art, the utility model aims to provide a liquid level measuring device for an electrolytic cell, which has strong corrosion resistance, is not easy to hang materials in a viscous medium, has accurate measuring results, and can monitor the liquid level of the electrolytic cell in real time, thereby improving the production efficiency and reducing the process cost.
In order to meet the requirements, the technical scheme adopted by the utility model is as follows: a liquid level measuring device for an electrolytic cell is an electrode type measuring device, electrodes are composed of at least two electrode rods with different lengths, the longest electrode rod is a public electrode, the rest electrode rods are measuring electrodes, an anti-explosion junction box is arranged at the non-liquid-connection end of each electrode and connected with a controller, and the controller is connected with the measuring electrodes and the public electrodes through leads.
Further, the measuring electrodes are two or more.
When the liquid level measuring device is used, the liquid level measuring device is hermetically connected with an electrolytic tank through a flange and a sealing gasket and is vertically arranged on the electrolytic tank, and the explosion-proof junction box is connected with the flange through threads. The sealing gasket can be a flat gasket, a step gasket and the like, and the gasket can also be replaced by a sleeve as long as the sealing requirement is met.
The liquid level measuring device measures the liquid level by utilizing the conductivity of the measured liquid. Once the liquid in the electrolytic bath touches the measuring electrode and the common electrode, the liquid is conducted, and a signal is detected. After the signal of the controller is amplified, a contact signal is output and displayed on a computer control system through an indicator lamp in the actual use process. The non-liquid-receiving ends of the electrodes are protected by an explosion-proof junction box, the liquid-receiving ends of the electrodes are all located within the liquid level variation range of the liquid to be measured and can be in full contact with the liquid to be measured, the electrode rod with the lowest physical position in the liquid-receiving ends is used as a common electrode, and the electrode rods except the common electrode are all used as measuring electrodes. Except for the common electrode, the length and the number of the measuring electrodes can be flexibly changed according to the liquid level height and the number requirement which need to be monitored, and multi-point control is realized. The controller detects whether a certain measuring electrode and the common electrode are conducted, if the certain measuring electrode and the common electrode are conducted, the liquid level of the measured liquid at least reaches the height of the measuring point, and if the certain measuring electrode and the common electrode are not conducted, the liquid level of the measured liquid does not reach the height of the measuring point. Thus, by the combined action of the common electrode and the measuring electrodes of different lengths, the range of the liquid level of the electrolytic cell can be determined. If all the measuring electrodes can be conducted with the common electrode, the liquid level of the measured liquid is higher than or equal to the height of the highest measuring point, and the control system displays that the number of the lighting grids of the indicator lamps is the number of all the measuring electrodes; if only one measuring electrode at the two adjacent heights is conducted with the common electrode, the liquid level of the measured liquid is between the heights of the two measuring points, and the control system displays the number of the indicator lights as the number of the measuring points and the number of the measuring electrodes lower than the measuring points; if all the measuring electrodes are not communicated with the public electricity, the liquid level of the measured liquid is lower than the height of the lowest measuring point, and the control system displays that the number of the lighting grids of the indicator lamps is zero.
The liquid level measuring device can select a large number of measuring points with different heights to monitor the current interval of the liquid level within the liquid level range of the liquid to be measured without calculating the common electrode, so that a control system can use all measuring electrodes as the measuring points or only a part of the measuring electrodes as the measuring points, and the flexibility of selection is higher in practical application.
When the liquid level measuring device is actually processed and manufactured, all parts can be made of different materials according to the requirements of the use parts. For example, the material of the electrolytic bath may be carbon steel or stainless steel, which has high corrosion resistance. The flange and the sealing gasket are made of polytetrafluoroethylene materials with strong corrosion resistance, sealing performance and electric insulation performance, and fluorinated ethylene propylene materials with similar performance can be selected, so that the cost is increased. When the flange is made of nonmetal, such as polytetrafluoroethylene. When the flange material is metal, like carbon steel or stainless steel etc. need install insulating pad additional between its surface and the part that the electrode exposes the flange, prevent that the circuit from colluding and leading to measuring result inaccurate, damage liquid level switch even. When the electrode rod contacts with liquid with strong corrosivity, the electrode rod is made of conductive metal materials with strong corrosion resistance and high strength, such as pure nickel, Monel or carbon steel. The selection of the form and material of each part does not reduce the protection scope of the utility model, which is also the important protection content of the utility model.
When the liquid level of the electrolytic cell is measured, the device is simple to mount, strong in corrosion resistance, accurate in measurement result, not easy to hang materials, long in service life and simple and convenient to replace the measurement electrode. The liquid level measuring device can monitor the liquid level at multiple points according to the actual production process requirements, ensures the continuous electrolysis of the electrolytic cell, improves the production quality and efficiency, reduces the equipment and personnel cost, and is suitable for industrial production application.
