Description

Sludge tumbling device

The present invention relates to a sludge tumbling structure, and more particularly to a sludge tumbling device for tumbling sedimentary sludge to make it muddy water, and then pumping muddy water with other suction devices for the purpose of removing sediment.

Generally, in order to prevent flooding and to have sufficient water supply in the dry season, the amount of rainwater or mountain springs is usually accumulated by constructing a reservoir. However, almost every year there is a typhoon attack in Taiwan. If the water and soil in the catchment area is not perfect enough, under the strong wind and heavy rain, it will often lead to terrible earth and stone flow, and the earth and rock flow will usually carry many sediments, stones and drifting wood streams. In the reservoir, over time, a large amount of silt, stones and driftwood were deposited at the bottom of the reservoir. The large amount of sedimentary silt not only reduces the water storage capacity of the reservoir, but also shortens the life of the reservoir invisibly. Therefore, regularly removing sediments such as silt and driftwood at the bottom of the reservoir can not only extend the service life of the reservoir, but also ensure the water storage capacity of the reservoir, which makes people have a shortage of water.

However, sedimentary silt and driftwood are denser and more dense due to long-term water pressure and accumulation. When they are to be removed, the general suction device cannot absorb it at all, and the high-pressure water column impacts the sludge and is often hindered by driftwood. Blocked, and the results are minimal. Inventors have also invented a device that can remove sediment deposits from reservoirs, such as the "Reservoir Sludge Removal Device" of the new patent No. M308273. The utility model mainly utilizes a plurality of water column nozzles connected to the sludge removing working platform, uses the high-pressure water column to turn the deposition sludge into a drifting sludge, and then uses a plurality of high-pressure gas exporting heads connected to the high-pressure gas generating working platform to face the floating mud toward the water surface. The direction is ascending, and then through the permanent channel inlet tower of the reservoir, and the hydropower water conduit, which is exported to hydropower equipment for power generation.

However, such a reservoir sludge removal device has the following disadvantages:

1. When the water column nozzle and the high pressure gas outlet head start to export the high pressure water column and the high pressure gas, the water column nozzle and the high pressure gas outlet head will not be directed to the place due to the function of the recoil force, so the diver is required to operate the water. However, each diver has only one hand, plus physical considerations, each job must require many divers, so it is quite labor and material resources.

2. The water in the reservoir is not very clear, and the visibility of the raised mud must be worse. It is not suitable for underwater operations and is prone to danger. At the same time as the silt is raised, the dispersed silt must be introduced into the hydropower equipment at the same time, and the undercurrent and eddies generated by it have a considerable threat to the life of the diver.

3. Directly pumping sewage containing a large amount of sludge into hydropower equipment to generate electricity. The large amount of sediment contained in the water may cause excessive wear of the generator set.

4. The high-pressure water and the high-pressure gas are operated separately. If the hidden garbage in the silt or the entire drifting drifting wood is blocked, the impact path of the water column will be blocked, and the water column will not directly impact the sludge, or the impact effect is not good, which leads to the subsequent Yang. The effect of rising sludge is not good.

The reason is that the inventor of the present invention has been continually researching and improving in the light of the perseverance and the inconvenience in the operation of the above-mentioned reservoir sludge removal device, and the actual operation and experiment. The present invention was developed and designed.

The main object of the present invention is to solve the above problems and provide a sediment which is mixed with sediment sludge, driftwood, etc., and floats the sludge and driftwood in a buoyant manner to float the whole sedimentation zone. For example, the submarine wreck is floated out of the sea surface by the airbag, which causes the agitation effect of the mud. The mode of operation is mainly based on the high-pressure water column power, supplemented by high-pressure gas. In addition to the high-pressure impact purpose, the high-pressure water column can guide the direction of the water column at the same time, so that the components of the present invention have a rotating effect, so that the water column impact direction is like a radial shape, and the rotary type impacts the sludge outward and downward, and is fixed downward by the fixed point. Drilling method, deep into the proper position inside the silt, stops to go deeper. At the fixed position of the silt, except for the high-pressure water column, the water column is continuously downward and outward, causing a flat hollow area, and the impact of the high-pressure water column simultaneously The high-pressure gas also rushes out of the body of the invention member to float the sludge, and at the same time, is poured into the flat, hollow region of the mud-free layer generated by the high-pressure water column at the point of internal impact of the sludge, thereby generating a pair The buoyancy effect of silt and driftwood, and with the continuous filling of high-pressure gas, the silt and driftwood are floated away from the original deposition position, and a large area of rapid tumbling mud and driftwood is obtained, so that it becomes muddy water in a large area, and then Mud water is pumped in conjunction with other suction devices to achieve a sludge tumbling device for the purpose of removing sediment.

In order to achieve the above object, the present invention mainly comprises a water inlet conduit, a water spray structure pivotally disposed at the bottom end of the water inlet conduit, and a plurality of radial connecting rods fixed at the center of the bottom end of the water inlet conduit. a jet structure and an intake pipe extending through the water inlet conduit and communicating with the air jet structure, wherein the water inlet conduit and the intake duct system respectively extend toward the water surface for respectively connecting the high pressure water source and the high pressure gas source, thereby The high-pressure water and the high-pressure air are respectively introduced into the water spray structure and the jet structure, and in the operation, the water jet and the air flow which impinge the deposition of the sludge are simultaneously sprayed in a high-pressure manner, and the high-pressure impact sludge of the water column can appropriately impinge on the high-pressure gas. The space area is so more favorable for the introduction of high-pressure gas, which is free from the improper appearance of high-pressure gas directly impacting the sludge.

This type of operation is not only deep and wide when tumbling the sludge, but also the operator does not need to sneak into the water, as long as the life jacket is used to ensure the safety of the person during operation.

The above and other objects and advantages of the present invention will be readily understood from
