Double-cone rotation vacuum drier internally provided with water spray pipes and scrapers

Abstract

The invention discloses a double-cone rotation vacuum drier internally provided with water spray pipes and scrapers. The problems that a drying device in the prior art is troublesome to clean, has potential safety hazards and is troublesome to use are solved. The double-cone rotation vacuum drier comprises a supporting frame, a double-cone-shaped drier body provided with a feed port and a discharge port, a rotating shaft, a vacuum pump, a vacuum filter pipe, a filter head, a discharge device, a drive motor, the two scrapers making slide contact with the inner wall of the double-cone-shaped drier body, scraper motors arranged on the portions, located at the positions of the feed port and the discharge port, of the double-cone-shaped drier body, a cleaning device arranged in the double-cone-shaped drier body, a vacuum pump electromagnetic valve used for opening and closing the vacuum pump, and a controller used for controlling the vacuum pump electromagnetic valve to be opened and closed. The discharge device comprises a discharge circular ring provided with an inner ring and an outer ring, screw grooves formed around the outer ring, and bag fixing strips arranged around the inner ring. The cleaning device comprises a water pipe, a pressurization pump, the water spray pipes, spray nozzles and a water pipe electromagnetic valve.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a double-cone rotary vacuum dryer with a built-in water spray pipe and a scraper. Background technique [0002] In the production of o-chlorophenylglycine and p-chlorophenylglycine, the drying process adopts a vacuum drying process, and the drying process adopts a double-cone dryer. The double cone dryer currently used in the market is a drying equipment integrating mixing and vacuum drying. However, there is a gap between the drying speed and drying time of this equipment in different drying environments. The working principle of this equipment is that during the drying process, firstly, the humidity on the surface is heated and vaporized and removed by the vacuum equipment. The humidity on the surface of the material should be gasified and gradually reduced, and a temperature difference is formed between the inside and the surface of the material. Under the action of temperature differ...
