Dual-driving lifting type transmission system of thickener

Abstract

The invention relates to a dual-driving lifting type transmission system of a thickener. The transmission system comprises five parts: a box body part, a dual-driving part, a rotating part, a lifting part and an electrical control part; the box body part is provided with a box body bottom plate which is welded with an external box body plate and an inner box body plate, and an upper bearing and a lower bearing are arranged in the box body; dual driving refers to a mode that left and right symmetrical pinions drive a large gear, and a reducer base is arranged, a planetary reducer is arranged on the reducer base and is connected with a gear reducer; the rotating part is provided with a large disc, the large gear is arranged on the large disc, a sleeve is welded with a reinforcing rib which is connected with the large disc, a key groove is formed in the sleeve, a flat key is arranged in the key groove and is connected with a lifting shaft, a scraping rake is arranged under a scraping rake shaft, a lifting shaft is provided with a key groove, a flat key is arranged in the key groove and is connected with the sleeve, a lifting gear motor is connected with a worm gear and a worm to drive a transmission shaft to lift, a lock nut and a pressing nut locating block are arranged at the lower end of the transmission shaft and are connected with the transmission shaft, the transmission shaft is arranged in a support frame, an electrical control cabinet is arranged and is provided with a torque transmission transducer for automatically controlling the gear motor to overload an electrical element and an alarm device.

Description

technical field

[0001] The invention relates to the field of thickeners for solid-liquid sedimentation separation equipment, and relates to a double-drive lifting transmission system for thickeners. Background technique

[0002] Thickener is the main equipment for the separation of solid-liquid suspension mixture after gravity sedimentation. It is widely used in industrial production, such as the thickener used in mineral processing plants to separate concentrate and tailings from clean water; Salt mud settling tank, which settles and separates brine and salt mud; separation of red mud from dissolution dilution liquid in alumina plant, concentration of waste water in sewage treatment plant and water purification plant, separation of leaching slag in hydrometallurgical industry, purification and separation of wet phosphoric acid, etc. Thickener equipment is widely used. Its working principle is to use the density difference between liquid and solid particles to generate relat...
