AI Technical Summary
The existing rotary resistance level switches are prone to monitoring failure in high temperature environments and lack effective heat dissipation and anti-blocking measures.
A high-temperature and anti-blocking rotary material level switch is designed. By setting a temperature sensor and a PLC in the protective case, the internal temperature is detected. When the temperature is high, the exhaust fan is activated to dissipate heat through the connecting pipe, and the material is discharged back into the storage device through the suction pump.
Effectively dissipate heat and prevent material blockage, ensure that the rotary resistance material level switch works normally in high temperature environments, and avoid monitoring failures.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rotary level switches, and particularly relates to a high-temperature resistant and anti-blocking rotary level switch. Background Technique
[0002] The rotary level switch uses a micro motor as a driving device, and the transmission shaft is connected to the clutch. When the material is not contacted, the motor runs normally. When the blade contacts the material, the motor stops rotating, the detection device outputs a contact signal, and at the same time, the power supply is cut off to stop rotating.
[0003] The existing rotary level switch is as Figure 1 shown. It is installed in a storage device for storing materials and is used for monitoring the material level. When it works, it will generate a certain amount of heat. If the heat is not dissipated in time, it is easy to cause the monitoring to fail. Therefore, it is necessary to develop a high-temperature resistant and anti-blocking rotary level switch. Summary of the Utility Model

Please refer to Figures 2 - 5 , a high-temperature and anti-blocking rotary vane level switch of this embodiment, which includes:
[0027] The rotary vane level switch 100, and the rotary vane level switch 100 includes a mounting flange 110 and a transmission shaft 120;
[0028] The protective housing 200, the protective housing 200 is provided at the bottom of the mounting flange 110. The protective housing 200 is a hollow cylinder. The transmission shaft 120 vertically penetrates the centers of the top wall and the bottom wall of the protective housing 200. A suction pump 210 and an exhaust fan 240 are provided at the top of the transmission shaft 120. The input end of the suction pump 210 is connected to the inner cavity of the protective housing 200 through a feed pipe 220. The input end of the exhaust fan 240 is communicated with the inner cavity of the protective housing 200 through a connecting pipe 250.
[0029] The inner cavity of the protective shell 200 is provided with a temperature sensor and a PLC, and the PLC is electrically connected to the temperature sensor and the exhaust fan 240.
[0030] The output end of the material suction pump 210 is provided with a discharge pipe 230, and the other end of the discharge pipe 230 is connected to a storage device for storing materials, so that the materials return to the storage device again.
[0031] The feed pipe 220 connected to the input end of the material suction pump 210 vertically penetrates through the mounting flange 110 and the top wall of the protective shell 200. The bottom opening of the feed pipe 220 is one centimeter away from the bottom of the inner cavity of the protective shell 200, which is convenient for sucking materials. The pipe body of the feed pipe 220 located in the inner cavity of the protective shell 200 is fixed by a fixing hoop, which increases the fixing stability of the feed pipe 220.
