Description

An intelligent sand mining platform

technical field

The invention belongs to the technical field of dredging equipment, in particular to an intelligent sand mining platform.

Background technique

In the field of dredging construction technology, sand mining is usually carried out by sand mining construction technology, and the sand source obtained from sand mining construction is used for land reclamation construction to form land. The traditional sand mining process is generally carried out by sand suction ship/sand mining ship facilities. The sand suction ship/sand mining ship lowers the end of the suction pipe vertically and inserts it into the surface of the sand, uses a centrifugal pump to absorb water, pressurizes it and sprays it through the nozzle. Undisturbed soil, and then use the suction pump to suck the mortar into the sand cabin for screening and washing.

The sand source obtained from sand mining construction is generally transported by sand barge. Sand barge is a ship used to transport sand source back and forth. In this kind of sand mining construction, in order to facilitate the sand barge to load and transport the collected sand source, it is usually necessary to set up a barge loading platform floating on the sea. During the process of loading and transporting the sand source, the sand barge stops at the The side orientation of the barge loading platform and receive the sand loading from the barge loading platform, and the sand barge will leave the barge loading platform after it is full.

Because the mud collected by sand mining facilities usually contains large pieces of earth and rock debris, on the other hand, dredging debris such as rocks and hard clay dumped by the previous construction unit are distributed to varying degrees on the surface of the sand mining area, and some It has been sunken and embedded in the silt layer, so the collected sand source cannot meet the quality requirements of the project construction, and needs to be screened to filter out the large particles to obtain a qualified sand source for land blowing. Fill in and use. Furthermore, under normal circumstances, project construction requires that the sand source has a certain mud content, so it is usually necessary to perform sand washing on the obtained mud to remove excess mud.

In the prior art, there are few equipment with dual functions of mud screening and sand washing treatment, which leads to the fact that the collected sand source cannot meet the construction requirements, and other measures need to be taken for sand source screening and sand washing treatment, which leads to The efficiency of construction is reduced, and the cost of construction is increased. On the other hand, because the working method of the sand suction ship/sand dredger has the characteristics of fixed-point sand extraction, it needs to be transferred to another water area for sand extraction after completing the sand extraction construction in one water area Construction, so the efficiency of sand mining is low, and the sand source at the bottom of the water cannot be fully used, which leads to the waste of sand source. For example, the application number is 2020211022768, and the patent name is "A washing machine for sand mining Sand platform", discloses "a sand washing platform for sand mining construction includes ship facilities, a screening tank and a sand washing tank are arranged on the ship facilities, and the inner chambers of the screening tank and the sand washing tank are connected. A screening device is installed in the screening tank, and a sand washing device is installed in the sand washing tank; the screening device includes an inclined screen screen, and the surrounding edges of the screen screen are fixedly connected with the inner wall of the screen tank. There are left and right slag outlets on the front of the screen plate, and two left and right slag discharge pipes. The top port of the slag discharge pipe is located in the slag discharge port and is fixedly connected; the sand washing device includes a driving roller and a driven roller. , a sand washing conveyor belt is arranged between the two, and a plurality of fixed blocks are arranged on the surface of the sand washing conveyor belt, and a plurality of sand buckets are installed and fixed on the fixed blocks, and a sand washing motor that drives the driving roller to rotate is also included. ; There is a mud pipeline at the stern of the ship facility, and the inner end of the mud pipeline extends into the screening tank, and also includes a transfer conveyor belt. The head end of the transfer conveyor belt is located below the end of the sand washing conveyor belt" and the application number is "2021211099393" , the patent title is "Sand washing platform based on sand mining ship", which discloses a kind of "A sand washing platform based on sand mining ship includes a ship with a ship engine room, and a sand mining device is installed on the ship; There is a sand washing tank in the middle of the sand washing tank, and a sand screening device is provided in front of the sand washing tank. The sand outlet of the sand screening device is connected with the sand washing tank. There is an inclined bottom plate between the walls, the lower edge of the inclined bottom plate is connected with the upper edge of the sand washing tank, and a sand washing device is installed between the two side walls, and the lower end of the sand washing device is located in the sand washing tank. Below the upper end of the sand device is installed a sand unloading device for laterally conveying and loading the received sand source, and also includes a lifting device for lifting and lowering the lower end of the sand washing device; a mining device is installed at the entrance of the sand screening device The sand input pipeline, the outlet of the sand mining device is butt-connected with the end of the sand mining input pipeline by connecting the flexible pipeline”;

Although the above two existing technologies combine sand washing and sand screening, although the versatility of the equipment has been improved and the functions are diverse in the process of use, there are also certain problems, for example, in the process of removing sand from different areas. When sanding, the amount of mud and sand in different areas is different. If continuous sand extraction is carried out according to a certain frequency, then for locations with more mud and sand areas, the amount of sand excavated per unit time will be large, which will be transported to the rear sand washing and screening device. The amount per unit time is also large, which reduces the quality and efficiency of sand washing and sand screening per unit time. For locations with less mud and sand areas, the amount of sand mining per unit time is small, and it is transported to the rear for sand washing and sand screening. The amount of mud and sand in the device is small, resulting in waste of equipment, so we hope that the amount of mud and sand collected in different sand mining locations will be different to make the amount of mud and sand transported to the rear sand screening and sand washing device consistent per unit time. So as to solve the problem that the mud and sand sometimes accumulate and sometimes loosen in the process of sand screening and sand washing. The inclined plate cannot be flexibly adjusted according to the use adjustment, and the angle adjustment of the sand mining pipe in the sand mining device is single. Therefore, we urgently need an intelligent sand mining platform to solve the above-mentioned problems.
