Description

Vacuum packed rotary drain pump for a dredging apparatus

The present invention relates to a vacuum maintenance rotary discharge pump for dredging devices such as soil, sand, sludge, sludge, manure, etc., such as rivers and sewers, and more specifically, to a soil, sand, etc. Dredging equipment such as soil, sand, sludge, sludge, manure, etc., which enables dredging of sludge, sludge, manure, etc., enables continuous dredging work, and enables easy movement and installation. It relates to a vacuum holding rotary discharge pump for dredging device.

In order to discharge sludge such as underground waste water, the conventional pump system is pumped by mixing with 60% or more of liquid so that the concentration of liquid can pass through the impeller of the pump, and also limit the particles of the dirt to pass through the impeller. It is composed.

In addition to the inconvenience of supplying water for mixing with 60% or more of the liquid, there is a problem that a complex facility is required to supply water to the place where sludge such as a river is located. In order to limit the particles of particles, various facilities such as a filtration device are required, and the maintenance of the pump is complicated by sludge contaminating the pump and shortening the life of the pump, or clogging by the solid mass. .

On the other hand, in order to discharge the liquid in the vacuum state, the suction force must be higher than the vacuum pressure of the tank to be discharged. In addition, it is impossible to discharge the dirt from the vacuum because it must be attached to the check valve or other various facilities.

Accordingly, the present invention is to solve this problem, it is possible to dredge the soil, sand, sludge, sludge, manure, etc. in the river and sewer using a simple structure and vacuum, and to enable continuous dredging operation The purpose of the present invention is to provide a vacuum maintenance rotary discharge pump for dredging devices such as soil, sand, sludge, sludge, and manure, such as rivers and sewers, which can be easily moved and installed.

In the dredging device having such a structure, when the vacuum pump 11 is operated, a vacuum is generated in the inflow pipe 21 to introduce soil, sand, sludge, sludge, manure, etc. through the inner pipe 26. At this time, the outside air is also sucked by the strong vacuum force through the air inlet 29 of the V-shaped end 28 of the inner tube 26 between the inner tube 26 and the outer tube 27, and the air sucked in this way The soil, sand, sludge, sludge, sludge, manure, etc. collide or penetrate and infiltrate the soil, sand, sludge, sludge, manure, etc. Dredging can be done easily. In addition, in the inflow process, the soil, sand, sludge, sludge, manure, etc., through the inlet pipe 21 can be easily flowed into the collection tank 20 by being mixed with the inhaled air and introduced at low vacuum pressure. .

In this way, the soil, sand, sludge, sludge, manure and the like introduced into the collection tank 20, the air in the collection tank 20 is sucked to the upper vacuum pump 11 side, mainly made of liquid and solids , Sand, sludge, sludge, and manure are settled downward by their own weight.

Soil, sand, sludge, sludge, manure, etc. precipitated to the bottom can be easily discharged by the rotary discharge pump 30 to the solid-liquid separator 51, such as a mesh belt-type conveyor.

In the solid-liquid separator 51, the liquid flows out to the lower part by the mesh belt and is separated from the solid component, and the solid component falls along the solid-liquid separator 51 to the solid-content collecting apparatus 53.

The liquid flowing out from the solid-liquid separator 51 is discharged back to the river by the liquid collecting / draining device 52, or centrifugal where the illustration is omitted depending on the conditions of soil, sand, sludge, sludge, manure, etc. It may be dewatered by a separator or the like.

The solid content collecting device 53 may be detachably installed on the moving means 60 or may be installed outside the moving means 60, and a vehicle or a cart such as a truck may be used at all. Thus separated solids collecting device 53 is installed, it is possible to discard the solids discharged continuously through the rotary discharge pump 30 and the solid-liquid separation device 51, accordingly, dredging operation is dredged continuously Can be discharged / disposal. Moreover, the solid content collection apparatus 53 may be equipped with the apparatus which compresses the collected solid content.
