Description

[Detailed Description of the Invention] This invention is a simple and effective method in which sediments from rivers, marshes, etc. are sucked up into a tank on land, and then pumped to another site with a pipe pipe for treatment. This invention relates to the disclosure of a vacuum, suction and pressure conveying method for precipitated deposits.

Therefore, in the conventional method of cleaning and removing this kind of sediment, two shovels and one wrecker were placed on a barge, and the sediment from the bottom of the water was scooped up by the shovel and temporarily stored in a collecting container such as a hopper. The process was carried out using a shovel underwater, which was inefficient, and the size of the float required for the float barge, making it unsuitable for narrow rivers. In this method, once the precipitate has accumulated in a container, it must be transferred to a transfer container and transported at any time, resulting in a disadvantage that the amount of precipitate that can be processed is small.

The present invention was devised in view of these inconveniences, and one of its main purposes is to collect sediment by suction and transport it to a dewatering treatment area, etc. This ensures quick processing without using transport equipment such as axles until the product is transported to the location.

Another main object of the present invention is to suction and collect sediment over a wide area, thereby making it possible to perform an even collection operation.

Furthermore, one of the main purposes of the pond in the present invention is to change the pressure inside the collection tank, and the suction vibrator and pressure feed/feeding device are Lifting device, pressure feeding device power j should work separately, and should the pipe cylinder be powered for a long time? This makes it possible to clean a wide area of a river without having to move other equipment.

History (Also, in the present invention, by making the arm crab equipped with an amphibious vehicle number, folding, turning, etc. possible, it is possible to capture mud etc. in any place. 1. Therefore, in order to achieve appropriate and purposeful follow-up of these custom-made products, the present invention is designed to provide an operating arm that is extendable and retractable.

In addition, a pressure feed pipe 51 a f is provided at the bottom of the collection tank 411J so as to communicate with the dehydration treatment device ([5)].
It's a small thing.

151d is closed, and the pressure feed supply folds [valve +21d, 131d' when activating 141] are closed.

The lifting device 131 uses a vacuum bomb, a pressure feeder, and a compressor.
It is planned that multiple vacuum pumps and compressors will be installed in parallel in accordance with the length of the suction pipe and pressure-feeding vibrator, and the suction pipe will be approximately 8
(Hlm, the length of the pressure pipe was approximately 700 m? This made it possible to expand the collection range of river sediments and facilitate smooth transportation to the dewatering treatment equipment, etc.).

Furthermore, Figure 12 [shows f? 2cl<lifting equipment+<1 darkness? Once connected to the pipe 131'a in parallel, the pipe 131'a is connected to the pipe 131'a so that the pipe 131'b is connected to the collection tank Ill.
I tried to use it in this way as much as possible.

Father, in the present invention, Il+ for the collection tank is connected in parallel (
I was worried about installing multiple units, so I decided to install an X-nitrogen pump. Is the collection tank 111 changed by switching the solenoid valve, while the contents of the other tank 111 are pumped? It was considered to be Machikita.

Furthermore, in this invention, it is planned to provide a submersible pump for transporting the contents in the collection tank Ill, and the tank 11 has the advantage that it does not have to be a high-pressure type. It's something to shoulder.

The present invention has the above-mentioned features, in particular, the free end of the operating arm can be telescopically extended to open the suction nozzle in the suction collection tube. A pumping device that suctions sediments such as sand, gravel, mud, etc., which are trapped in a collection tank into a collection tank under reduced pressure through a suction collection pipe, and pressurizes the inside of the collection tank and lifts it out and captures it. By comprising a device for pumping and supplying the precipitated sediment to a dehydration treatment device, it is possible to
Example flaw? This can be effectively corrected, and the following internal effects are expected to be achieved.

That is, in the present invention, 15 units in 1ill of collection tank are replaced by vacuum pump, compressor, etc. With this, suction and pressure feeding can be freely carried out, and the sediment can be kept constant.
When it accumulates in the tank, pressurize 4 [by switching to
This allows for smooth and quick transportation to the dehydration treatment sample 1 or to the final treatment equipment without transferring to a pond container or acid feeder.

In addition, in the present invention, it is made to be expandable and contractible.7: 4Jj
! The l'E arm is designed to collect sediment such as sludge from every corner of the riverbed. Furthermore, by using an amphibious vehicle equipped with the operating arm, the operator can operate on the bottom of the water or in wetlands without any inconvenience or risk to the operator. This prohibits people's clothes from being soiled.

(In the present invention, by connecting a vacuum pump and a compressor in parallel, an appropriate pressure f f'fi can be set depending on the length of the pipe, the viscosity state of the sediment, etc.)

Work efficiency? This is similar to the above.

As can be seen in soft soil, the present invention includes a lifting device, a collection tank, and a feeding device for suctioning sediments. Transport it to a dehydration treatment facility or other transport location. The main purpose of this publication is to disclose a vacuum, suction and pressure transfer method for materials deposited.
