Therefore, the most common conveying mode of the organic garbage is a spiral conveying process, the spiral conveying process comprises a shaft spiral conveying process and a shaftless spiral conveying process, and the following defects are also caused in the actual operation process:

(1) turning is inconvenient, a spiral conveying process cannot directly turn, so that only one set of spiral conveying system can be independently added, if materials need to be subjected to diversion conveying for many times, a plurality of sets of spiral conveying systems are needed, the conveying systems become very complex, the occupied space is large, the investment is greatly increased, the number of the conveyed spirals is large, the possibility that a motor breaks down is high, the instability of each conveying system is directly caused, and the normal operation of the whole system is influenced.

(2) The material falls and the problem of leaking, because organic rubbish moisture content is high, and has certain extrusion force when screw conveyor, the apron clearance above just being followed easily is extruded to some materials, and water also can spill from both ends, simultaneously because the material is rotten smelly very easily, causes the ground health situation very poor, and the space is full of the stench. The surrounding environment is adversely affected, and the surrounding residents are easy to dismantle.

(3) The energy consumption is high, if the conveying distance is long, the direction is changed for many times, the conveying energy consumption is very high, and the energy-saving and environment-friendly requirements cannot be met.

Detailed Description

The present invention is further illustrated by the following examples, which are only a part of the examples of the present invention, and these examples are only for explaining the present invention and do not limit the scope of the present invention.

The utility model provides an organic waste conveying system, core conveying unit adopts special solid delivery pump 1, adopts the pipeline mode of carrying, utilizes unique pipe fitting and valve, the material direction of delivery in the control pipeline to realize one set of system's multiple spot and carry, the transport point of automatic control material. The material is transported in the pipeline in a full-sealed mode, the phenomena of water leakage and material falling are avoided, the automation, energy conservation, environmental protection and multifunction are integrated, and the sanitation condition of the site environment is greatly improved. Simultaneously in order to solve pipeline system's the material problem of hiding, the supporting high-pressure gas cleaning device that sets up utilizes high-pressure gas, blows the material to the delivery point, guarantees not stock in the pipe, does not smelly. Furthermore, in order to ensure the cleaning effect, a sectional cleaning mode is adopted to prevent incomplete cleaning caused by insufficient gas pressure.

As shown in the attached figure 1 of the specification, the conveying system mainly comprises a solid conveying pump 1, a conveying mechanism and a cleaning mechanism, wherein the conveying mechanism comprises a conveying pipe 2 and a plurality of discharge ports 3 which are arranged at intervals along the length direction of the conveying pipe 2, the discharge ports 3 are used as conveying points of materials, and each discharge port 3 is provided with a gate valve; the cleaning mechanism adopts an ultrahigh pressure air compressor 4, is communicated with the conveying pipe 2 through a cleaning pipe and is used for discharging residues in the conveying pipe 2 from a discharge port 3 for opening the gate valve through air pressure, and a pneumatic valve 6 is arranged on the cleaning pipe.

In an embodiment, the material through sorting, crushing and dewatering enters the solid delivery pump 1 through the feed hopper 101, in order to avoid bridging and adhesion of the material on the wall of the feed hopper 101, causing the material to block up and affecting the normal conveying phenomenon, two material vibrators 102 are installed on the outer wall of the feed hopper 101, the bridging phenomenon of the material is damaged by using the high-frequency vibration principle of the material vibrators 102, and meanwhile, the adhesion of the material on the feed hopper 101 is prevented, so that the smooth material delivery is ensured, and the material smoothly enters the following solid delivery pump 1. The materials are pressurized by a solid delivery pump 1 (plunger pump, screw pump, rotor pump) and delivered to each delivery point by a delivery pipe 2.
