Abstract
The utility model relates to a rotary paddle level switch comprising a casing cover, a casing, a cable connector, a seal ring, a motor, a sensing component, a coupling, a support plate, a support sleeve, a screw plug, a transmission shaft, a bearing and a blade. The output shaft of the motor is connected with the transmission shaft by the coupling. The rotary paddle level switch is characterized in that the casing cover and the casing are connected by threads, the O-shaped seal ring is arranged between the casing cover and the casing, the transmission shaft is supported by the support sleeve and the bearing which are arranged in the casing, the support sleeve is arranged at the part of the transmission shaft, extending out of the casing, oil seals are arranged among the support sleeve, the screw plug and the transmission shaft, and the cable connector is a waterproof and dustproof cable connector. The rotary paddle level switch is simple and reliable in structure and convenient to make, arrange and use. As the integral seal is reliable, the transmission shaft part extending out of the casing is supported by the support sleeve, and the output shaft of the motor is connected with the transmission shaft by the coupling having overload protection, the detection accuracy of the rotary paddle level switch is effectively improved, and the service life of the motor, even the whole machine is extended.
Description
Technical field
The utility model technology relates to stuff level switch, particularly is a kind of blocking rotary type stuff level switch.
Background technology
The material level that the blocking rotary type stuff level switch is widely used in various solid materials detects and control, and its blade is not when contacting material, and motor normally rotates, and when blade contact material, resistance stops the rotation blade, exports a contact point signal, cuts off motor power with the protection motor.Existing blocking rotary type stuff level switch adopts the sealing means of rubber blanket usually, and along with long Effect of Hyperthermic Environment, dust can enter its inside, has a strong impact on its serviceable life; Simultaneously, the bearing of supporting shaft, especially transmission shaft stretch out the bearing at housing position, owing to be subjected to temperatures involved for a long time, occur often rotating inflexible phenomenon, influence the accuracy of detection of blocking rotary type stuff level switch; In addition, because no overload protection arrangement damaged motor easily when blade bore heavy load.Therefore, design a kind of good airproof performance, high temperature resistant and to have a blocking rotary type stuff level switch of overload protection very necessary.
Summary of the invention
The purpose of this utility model is exactly that a kind of good airproof performance, high temperature resistant and have a blocking rotary type stuff level switch of overload protection will be provided.
For achieving the above object, the utility model adopts following technical scheme: a kind of blocking rotary type stuff level switch, comprise cap, housing, cable splice, O-ring seal, motor and sensing element, shaft coupling, support plate, supporting sleeve, plug screw, transmission shaft, bearing and blade, motor output shaft is by shaft coupling and propeller shaft couplings, it is characterized in that described cap and housing are by being threaded, be provided with o shape O-ring seal between described cap and the housing, described transmission shaft is by the supporting sleeve and the bearings that are arranged in the housing, described supporting sleeve is arranged on transmission shaft and stretches out the housing position, described supporting sleeve, be provided with oil sealing between plug screw and the transmission shaft, described cable splice is the water proof and dust proof cable splice.
Further, described oil sealing is high temperature resistant oil sealing.
Further, described shaft coupling is the shaft coupling with overload protection.
During the utility model work,, avoid dust to enter because integral sealing is reliable; Transmission shaft stretches out the housing position and adopts supporting sleeve to support, and has overcome the problem that bearing lost efficacy easily; Motor output shaft and transmission shaft adopt the shaft coupling with overload protection, and transmission shaft will skid at coupling band during the blade overload; Therefore, effectively improved the accuracy of detection of blocking rotary type stuff level switch and the serviceable life of motor and even complete machine.The utility model is simple and reliable for structure, making, installation and easy to use.
