Description

Channel long side slope dredging filter

technical field

The invention belongs to the technical field of dredging rivers, and in particular relates to a dredging filter for long side slopes of channels.

Background technique

At present, the commonly used dredging technologies are mainly divided into two categories. The first category is to drain the water in the river or canal through cofferdams or interception, and then enter the river through engineering machinery to excavate and clean the sediment layer. The second category is to use special dredging machinery such as cutter suction dredgers, rotary bucket dredgers and other equipment to directly perform dredging work on the water surface. For the first type of dredging method, the amount of work is large and the cost is high, but the cleaning effect is better than other dredging methods; the second type of dredging method does not need to cut off the water flow, and does not affect the normal use of rivers or canals. The amount is small, but the dredging efficiency is average.

Due to the inclined slope of the river channel or channel, it is not suitable for construction machinery to drive on it for dredging operations; cutter suction dredgers and rotary bucket dredgers are easy to damage the hardened cement surface of the slope during the dredging process. In addition, the cleaned silt cannot be discharged on the spot. Due to the high water content of the silt, if it is not filtered and collected directly to the designated place, the transportation cost will be greatly increased due to the large volume of the silt (mainly water).

Above the slope, the support wheel of the disc dredging suction device moves on the slope with the progress of the engineering vehicle. During the movement, the first rotary driver drives the cutter shaft to rotate, and the left helical blade and right helical blade on the cutter shaft Remove the silt and sundries deposited on the slope. Since the left helical blade and the right helical blade rotate in the opposite direction, the left helical blade will remove the silt and debris and gather them to the right, and the right helical blade will break the silt and sundries. After that, it is transported to the left, that is, the broken sludge and sundries are concentrated in the middle of the cutter shaft, and at the same time, the high-pressure water sprayed from the jet nozzle scours the slope surface, and the sludge pump pumps the sludge mixture from the suction port to the filter box of the sludge filter device. The second rotary driver drives the brush roller to rotate, and the brush roller cleans the slope surface, and transports the cleaned mud and sundries forward to the bottom of the water inlet, so as to further improve the cleaning effect.

It tilts backward at a certain angle, which can effectively clean up the difficult-to-remove silt or algae in the gap, and push the silt debris to move backward to the bottom of the suction port, improving the sewage suction effect.

The brush roller made of nylon is used to clean the slope at the end and completely remove the mud and debris from the slope. And through the rotation of the brush roller, the sewage in the casing is driven to flow to the water outlet, so as to improve the suction effect of sewage.

The engineering vehicle drives the disc-type dredging suction device to remove the silt and debris on the surface of a height of the slope, and then starts the rotary mechanism, which drives the folding arm to rotate, and at the same time starts the hydraulic cylinder to adjust the inclination angle of the telescopic arm. The arm drives the disc dredging suction device to move up or down on the slope through the boom, so that the silt and debris can be removed from the surface of another height of the slope, and in this way until the silt on the slope is removed All debris removed.

A reserved hole can be set on the front side of the casing, and a soil turning device can be installed for a relatively hard soil layer, so as to reduce the working pressure of the left helical blade and the right helical blade.

Sewage (silt and debris mixture) is pumped into the filter box by the sludge pump and falls onto the deflector. The deflector guides the sewage to the filter screen. The filter screen filters the sewage and passes through the permeable holes on the bottom plate. Fall into the settling tank for sedimentation. When the water level in the settling tank is higher than the side of the overflow plate, the water will overflow from the top of the overflow plate and be discharged from the filter box through the filtered clean water outlet. The water can be discharged into other parts on the engineering vehicle. The water tank may be further treated in the sewage treatment equipment. If it is basically up to the standard after being settled in the internal temporary sedimentation tank, it can be directly discharged back into the channel.

When the filter screen has been filtered for a long time, its filtering effect will be reduced. At this time, it is necessary to perform reverse cleaning on the filter screen. High-pressure clean water is introduced into the backwash pipe, and the backwash nozzle sprays the filter screen. At the same time, shake the handle , drives the lower shaft to rotate, and the lower shaft drives the upper shaft to rotate through two belts. During the rotation of the belt, it drives the slide bar to move up or down along the slideway, and the backwash pipe on the slide bar also moves up and down, so that The entire surface of the filter screen is subjected to reverse high-pressure flushing, and the sundries attached to the front surface of the filter screen are washed away, and are discharged through the backwashing sewage outlet along with the water flow.

After the backwashing mechanism is installed outside the filter box, the drawer-type backwash filter mechanism in the present invention is pushed into the filter box from the upper opening of the front side of the filter box until the front side plate is flush with the front side of the filter box. Fixed as one. This split-type production and installation method implements the modular design concept, which is convenient for assembly, disassembly, maintenance and cleaning.

Lifting lugs are used for hoisting to engineering vehicles or carrying sludge filtering devices.

The drawer-type backwash filter mechanism adopts a split design with a built-in small sedimentation tank, which can do simple sedimentation treatment on the sludge water. When there is a lot of sediment in the sedimentation tank, the sewage pump will be suspended, and the sedimentation debris outlet will be opened to discharge the sedimented sludge. .

The inside of the filter box is designed with a backwash mechanism for the filter screen, which can prolong the working time of the filter screen, improve the filtration efficiency of the filter screen, and reduce the frequency of shutdown and cleaning.

To sum up, the principle of the present invention is similar to the pump-suction desilting technology. It mechanically removes the sludge and debris, and uses high-pressure water to wash away the sludge, and then the sludge is sucked into the sludge filter device by the sludge pump for preliminary filtration. . The overall volume of the present invention is small, flexible in action, and can be cleaned while moving without affecting the running water and normal use of the channel.
