In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
As shown in fig. 1 and 2, in the present embodiment, an overtemperature double protection interlock device for CBD component separation of industrial hemp is provided, which comprises a heat-conducting oil tank 1, a controller 2 and a temperature controller 3; a temperature transmitter 14 and an electric heater 15 are arranged on the heat-conducting oil tank 1, the temperature transmitter 14 is connected with the controller 2, and a first alarm 23 is connected to the controller 2; a thermocouple 16 is arranged in the electric heater 15, the electric heater 15 is connected with the controller 2 through an alternating current contactor 31 and a solid state relay 21, the alternating current contactor 31 and the thermocouple 16 are both connected with the temperature controller 3, and the temperature controller 3 is connected with a second alarm 32.
In this embodiment, the heat-conducting oil tank 1 is connected to the head tank 4 through the heat-conducting oil outlet pipe 12 and the heat-returning oil pipe 11, the heat-conducting oil outlet pipe 12 is provided with the circulating pump 13, and the circulating pump 13 is connected to the controller 2 through the motor starter 22.
In this embodiment, the connection point of the heat-conducting oil outlet pipe 12 and the heat-conducting oil tank 1 is located below the connection point of the heat-returning oil pipe 11 and the heat-conducting oil tank 1.
In this embodiment, the connection point of the heat outlet pipe 12 and the material tank 4 is located below the connection point of the heat return pipe 11 and the material tank 4.
In this embodiment, the ac contactor 31 is connected to the controller 2 via a solid-state relay 21.
In this embodiment, a heating resistance wire is disposed inside the electric heater 15, and the thermocouple 16 is in contact connection with the heating resistance wire.
In this embodiment, the top of the raw material tank 4 is provided with a stirring motor 41 and a feeding port 43, and the bottom of the raw material tank 4 is provided with a discharging hand valve 42.
In this embodiment, the operating principle of the over-temperature dual-protection interlocking device is as follows:
the controller 2 starts the conduction oil circulating pump 13 through the motor starter 22, starts the oil temperature automatic control after about two minutes of delay (the time length is preset in the controller 2, and the time length can be set according to specific conditions), and detects the temperature of the conduction oil in real time through the temperature transmitter 14 to control the power on and off of the electric heater 15, so that the oil temperature is kept at a set value, namely the temperature required by the process.
When the heat conduction oil exceeds the temperature high limit (set according to the actual condition), the controller 2 automatically stops the automatic control of the heat conduction oil, cuts off the power supply of the electric heater 15, and triggers the first alarm 23 to make a sound. When the temperature transmitter 14 is damaged or the conduction oil circulating pump 13 is abnormal, which causes the circulation of the conduction oil to be not smooth, and the like, the temperature of the conduction oil detected by the temperature transmitter 14 does not reach the set value of the process temperature, the controller 2 can continuously supply electricity to the electric heater 15 through the solid-state relay 21, and the temperature of the heating resistance wire of the electric heater 15 is possibly too high.

The controller 2 and the temperature controller 3 are two mutually independent control parts and do not influence each other, so that double interlocking protection of the overtemperature of the heat conducting oil is provided. Related technicians can check the reason that the temperature of the heat conduction oil exceeds the limit and the reason that the temperature of the heating resistance wire exceeds the limit according to the alarm conditions of the first alarm 23 and the second alarm 32, and timely response is made, so that the influence on the production efficiency and the production quality is avoided.
In this embodiment, in the actual production process, the working process of the over-temperature dual-protection interlocking device and the raw material tank 4 is as follows:
before production, crude oil extracted from industrial hemp is fed into raw material tank 4 through feed inlet 43, at this time, the crude oil is relatively viscous, and the initial operation frequency of stirring motor 41 is 5-10 Hz.

At this time, the operation frequency of the stirring motor 41 can be appropriately adjusted. When the heat conduction oil exceeds the temperature high limit (set according to the actual condition), the controller 2 automatically stops the automatic control of the heat conduction oil, cuts off the power supply of the electric heater 15 and triggers the first alarm 23 to make a sound. When the temperature transmitter 14 is damaged or the conduction oil circulating pump 13 is abnormal, which causes the circulation of the conduction oil to be not smooth, and the like, the temperature of the conduction oil detected by the temperature transmitter 14 does not reach the set value of the process temperature, the controller 2 can continuously supply electricity to the electric heater 15 through the solid-state relay 21, and the temperature of the heating resistance wire of the electric heater 15 is possibly too high. The temperature controller 3 detects the temperature of the heating resistance wire of the electric heater 15 through the thermocouple 16, controls the AC contactor 31 to be conducted when the temperature is lower than the safety temperature, and directly disconnects the AC contactor 31 once the heating resistance wire of the electric heater 15 exceeds a temperature set value (set according to actual conditions), thereby disconnecting the power supply main loop of the electric heater 15 and triggering the second alarm 32 to make a sound. The controller 2 and the temperature controller 3 are two mutually independent control parts and do not influence each other, so that double interlocking protection of the overtemperature of the heat conducting oil is provided.
