Description

Convenient-to-operate movable air suction cover

Technical Field

The utility model relates to a cable masterbatch production line equipment, concretely relates to portable cover that induced drafts of convenient operation in cable masterbatch production line.

Background

When the cable master batch is prepared, the mixed master batch is generally extruded through an extruder, a cutting knife is arranged at a discharge port of the extruder, and a plurality of extruded master batches are cut into master batch particles. Because the master batch particles after extrusion cutting are in a high-temperature state, the master batch particles are conveyed to a cooling device through an air conveying pipeline, cooled and filtered and packaged after harmful waste gas dissipated under the high-temperature condition is pumped out.

The master batch can be mixed by an internal mixer and/or a double-screw extruder before being extruded, and then the mixed material is extruded and cut by a single-screw extruder. When the material is extruded from the twin-screw extruder, the discharge port of the twin-screw extruder is generally arranged above the feed port of the single-screw extruder, and the mixed material directly enters the single-screw extruder for extrusion. Corresponding material guide pipelines or material guide devices can be arranged between a discharge port of the double-screw extruder and a feeding port of the single-screw extruder, but materials are easy to stay in the material guide pipelines or the material guide devices due to expansion and high-temperature and easy-adhesion states when being extruded from the double-screw extruder, and the material guide pipelines or the material guide devices do not have the self-cleaning function of the extruder screws, so that different batches of mixed materials (mixed colors) are easy to cause, and the product quality is influenced.

Based on the above situation, an open structure is generally arranged between the discharge port of the double-screw extruder and the feed port of the single-screw extruder, that is, the discharge port is aligned with the feed port, and the extruded material is directly fed into the single-screw extruder. The structure has another advantage that the feeding condition can be observed conveniently at any time, but harmful gas dissipated by high-temperature materials under the structure can be directly discharged to a production site, so that serious environmental protection problems are brought to the site. For this purpose, it is generally necessary to dispose an air suction hood above the device, collect the escaping gas by negative pressure, and dispose the gas. The suction hood is too high, the collection effect is not good, so the suction hood is preferably set to be tightly attached to the height of the discharge port and the feeding port, and the observation and treatment of the feeding condition of field operators can be influenced due to too low arrangement.

In the scheme designed by the inventor, the movable air suction hood is convenient for field observation and treatment, and the positioning of the movable air suction hood is realized through the air cylinder and the rotating bayonet lock which is in rotating and abutting connection with the sliding block. However, this structure has problems of many parts, complicated manufacturing, high manufacturing requirement, and insufficient accuracy in use, and if the accuracy is improved, the cost is high, and if the accuracy is insufficient, the use is inconvenient, and there are many troubles such as jamming. And the bayonet lock is rotated by manual direct operation, which is inconvenient and has certain potential safety hazard.
