Abstract
The utility model relates to an experiment instrument, in particular to an intelligent self-control type heat connecting magnetic stirrer. Under the condition that the basic performance of an existing heat collecting magnetic stirrer is not changed, a safety control and intelligent alerting device is additionally arranged. According to the liquid level change of a heat-transfer medium, when the liquid level is reduced to the alerting position of the lowest liquid level, a buzz is generated and an operator is alerted in time. When the liquid level is reduced continuously to a safe liquid level position, a power supply of a resistive heater is automatically cut off, so that heating is stopped and the other kind of buzz is generated. Due to the adoption of the mode of an intelligent self-control device, under the condition that the operator is on duty, the operator does not need to pay attention to the heat collecting magnetic stirrer in real time and the time of the operator is saved. Under the condition that the operator is not on duty for a long time, the heat collecting magnetic stirrer can be safely protected and the accident of a laboratory fire disaster is avoided.
Description
Technical field
The utility model relates to laboratory apparatus, particularly a kind of Intelligent automatic-control type heat-collecting magnetic stirring device.
Background technology
The heat-collecting magnetic stirring device is that a kind of Yi Shui, oil are heat transfer medium, is used for the laboratory apparatus of heated at constant temperature and stirring, and is extensive in the laboratory applications of colleges and universities, enterprise.Temperature according to heat transfer medium, control heating power that can be constant, but in long-time high temperature bath or oil bath agitating heating process, water or oil level drop to below the safety level line, until water, rusting are done, process such as untimely discovery, may cause instrument to burn, cause short circuit to cause the laboratory fire when serious, this phenomenon is frequent occurrence in the laboratory.
The utility model content
The purpose of this utility model be to provide a kind of can automatic cut-off power and implement the Intelligent automatic-control type heat-collecting magnetic stirring device of reporting to the police.
The purpose of this utility model is achieved through the following channels: a kind of Intelligent automatic-control type heat-collecting magnetic stirring device, it comprises base with control device, is positioned at the thermal-arrest pot of base top and in-built electrical heater and agitator and the temperature acquisition inductor that is positioned at thermal-arrest pot top, on the pot wall of thermal-arrest pot magnetic float level indicator is installed, the magnetic float switch is installed on the magnetic float level indicator shunt valve outside, and the magnetic float switch connects the interior electric heater unit of control thermal-arrest pot by the open type relay.
As the further optimization of this programme, described magnetic float switch connects the external buzzer of control.
As the further optimization of this programme, described buzzer is located on the base side wall.
The utility model Intelligent automatic-control type heat-collecting magnetic stirring device, do not changing under the existing heat-collecting magnetic stirring device key property prerequisite, increase security control and intelligent reminding device, utilize the heat transfer medium level change, when liquid level drops to the minimum level warning position, send a kind of buzzer, in time remind operating personnel, when liquid level continues the safety level position of decline, automatically cut off the power supply of resistive heater, stopped heating, and send another kind of buzzer.The utility model is having under operating personnel's prerequisite on the scene by adopting the mode of Intelligent automatic-control device, and operating personnel do not need to wait in real time heat-collecting magnetic stirring device, releasing operation personnel's time yet; In the situation of long-time nobody value of keeping, protection heat-collecting magnetic stirring device that also can safety prevents the generation of the accident of laboratory fire.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Among the figure, base 1, thermal-arrest pot 2, electric heater unit 3, control device 4, magnetic float level indicator 5, temperature acquisition inductor 6, magnetic float switch 7, buzzer 8, agitator 9.
The specific embodiment
As shown in Figure 1, the utility model Intelligent automatic-control type heat-collecting magnetic stirring device, it comprises the base 1 with control device 4, be positioned at base top and in-built electrical heater 3 and the thermal-arrest pot 2 of agitator 9 and the temperature acquisition inductor 6 that is positioned at thermal-arrest pot 2 tops, it is characterized in that: on the pot wall of thermal-arrest pot 2 magnetic float level indicator 5 is installed, magnetic float switch 7 is installed on the magnetic float level indicator 5 shunt valves outside, magnetic float switch 7 connects the electric heater unit 3 of controlling in the thermal-arrest pot 2 by the open type relay, the buzzer 8 on base 1 sidewall is located in described magnetic float switch 7 connection controls.
The course of work of the utility model Intelligent automatic-control type heat-collecting magnetic stirring device is as follows: when the heat transfer medium liquid level reached minimum level, magnetic float switch 7 was as the output of electric terminal signal, and 8 work of control buzzer are sounded a buzzer; When the heat transfer medium liquid level reached safety level, magnetic float switch 7 was as the output of electric terminal signal, and control open type relay cuts off electric heater unit 3 power supplys, controls simultaneously buzzer 8 work, sounds a buzzer.
