A high-efficiency ship unloader with combined spiral and negative pressure conveying

Abstract

The present invention discloses a high-efficiency ship unloader with combined spiral and negative pressure conveying, comprising: a mobile vehicle, a lifting platform mechanism, a rotating support column, a cross beam, a rotating drive mechanism, a vacuum feeder, a screw conveyor, a telescopic drive mechanism, and a negative pressure suction pipe. During the initial ship unloading, the screw conveyor is started first. The material enters the silo through the discharge port at the top of the screw conveyor, the first telescopic pipe, and the second feed port, and finally is discharged through the discharge port. During the hold cleaning, the screw conveyor is turned off and the vacuum feeder is started. A negative pressure suction force is generated in the negative pressure suction pipe to suck the material at the bottom of the hold into the chamber of the vacuum feeder, and then enters the silo through the discharge port of the chamber and the first feed port, and finally is discharged through the discharge port, thus realizing the dual-function unloading of spiral and negative pressure. Moreover, the positions of the screw conveyor and the negative pressure suction pipe can be moved in real time through the lifting platform mechanism, the rotating drive mechanism, and the telescopic drive mechanism, which is convenient for removing the material in the hold.

Description

Technical Field

[0001] The invention relates to the technical field of ship unloaders, and more particularly to a high-efficiency ship unloader for combined conveying of screw and negative pressure. Background Art

[0002] Ship unloader is a common equipment for unloading bulk materials at ports. It can be widely used for unloading bulk materials in powder, granular, block or mixed forms.

[0003] At present, the screw unloader is widely used in ship unloading operations, but there are also negative pressure suction unloaders. The two equipments have their own characteristics. The screw unloading system is energy-saving, low-noise, light dust, and high productivity, but after the work is completed, there is a lot of material remaining at the bottom of the cabin, and it cannot be unloaded in one go, and the workload of clearing the warehouse is large; while the negative pressure unloading system is similar to a vacuum cleaner, which can almost unload the material at the bottom of the cabin, with less dust, but the production efficiency is low, and it is noisy and energy-consuming. This machine is more suitable for small inland ships, and is rarely used for large tonnage ships due to the comprehensive indicators such as productivity and energy consumption.

[0004] Therefore, how to provide a high-efficiency ship unloader with combined spiral and negative pressure conveying is a problem that technical personnel in this field need to solve urgently. Summary of the invention

[0005] In view of this, the present invention provides a high-efficiency ship unloader with combined spiral and negative pressure conveying.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0034] The beneficial effect of adopting the above technical solution is that the provision of the anti-slip plate can prevent the connecting beam from slipping off the cross beam.

[0035] Furthermore, a first material anti-blocking auger is provided at the discharge port of the chamber of the vacuum suction machine, and a second material anti-blocking auger is provided at the discharge port on the lower silo wall of the silo.
