Sludge collecting device of hidden culvert dredging robot

Technical Field

The utility model relates to a secretly contain the desilting, especially one kind is used for preliminary treatment silt, improves the silt collection device of secretly containing desilting robot of desilting efficiency.

Background

Along with the aggravation of the urbanization process, the space of a plurality of urban river channels is continuously occupied and squeezed, and part of river channels are transformed into hidden culverts. When the naturally flowing river channel is transformed into a hidden culvert, the river channel has multiple functions of flood discharging, waterlogging draining, water storage, landscape, humanity and the like, only remains the flood discharging function, and the overground building often steals sewage into the hidden culvert, and the hidden culvert is in a dark and closed space for a long time, so that anaerobic odor is easily generated, sludge is deposited, and the river channel becomes a 'dead river'. Aiming at the hidden culvert type river channel, the most effective mode is to open the hidden culvert, so that the river is reproduced, if the hidden culvert is covered with a building, the open river is difficult to recover, various measures such as sewage interception, first desilting, maintenance desilting and the like can be carried out on the hidden culvert type river channel to reduce the adverse ecological influence of the hidden culvert type river channel on the river channel.

The existing blind culvert dredging means are usually carried out manually, construction personnel are cleaned, an oxygen mask is worn on the head, a life jacket is worn on the body, a toxic and harmful gas detector and lighting equipment are carried in the hands, the cleaning speed is low, the danger coefficient is large, the blind culvert can not stand even in narrow blind culvert sections, and the cleaning difficulty is greatly increased; to some longer dark culverts, also can select at the road surface opening, the segmentation is cleared up, and this kind of mode is wasted time and energy, very big increase the cost of clearance, and poisonous foul gas in the dark culverts in addition still can influence peripheral crowd. Also there are some desilting robots, collect silt to the collection incasement through straw or scraper bowl, treat that the collection case fills up the back and change empty collecting box, full collection wants then to transport the dark culvert and handles, but because contain a large amount of moisture in the silt, lead to its volume and weight great, need often change the collecting box, increased change time and cost of transportation, lead to desilting efficiency not high.

Disclosure of Invention

The utility model aims to solve is that contain a large amount of moisture in the silt, and the desilting in-process needs often to change the collecting box, leads to the problem of inefficiency, provides one kind and is used for preliminary treatment silt, improves the secretly culvert desilting robot silt collection device of desilting efficiency.

The utility model discloses a dark culvert desilting robot silt collection device installs on the frame of desilting robot, its characterized in that this silt collection device installs lower part behind the frame, including conveyer belt, conveying baffle, dehydration bucket, collecting box, electric fan heater and rotating electrical machines, the conveyer belt sets up in the frame lower part, two conveying baffle vertical fixation are in conveyer belt both sides, the dehydration bucket is the slope setting that the entry is high, the export is low, the entry sets up in the conveyer belt rear end, the export sets up above the collecting box, the dehydration bucket is connected with the rotating electrical machines, the rotating electrical machines drives the dehydration bucket and rotates; the conveying baffle is internally provided with a cavity, a plurality of air outlets are equidistantly arranged on the side wall, the air outlet direction of the air outlets faces the surface of the conveying belt, and the cavity of the conveying baffle is connected with the fan heater.

The conveyer belt on be provided with the filtration pore, filtration pore diameter is no more than 1mm, unnecessary moisture in the silt drops from the filtration pore.

The wall of the dehydration barrel is provided with a filter hole, the diameter of the filter hole is not more than 1mm, excessive moisture in the sludge falls from the filter hole, and the moisture is reduced to the greatest extent to enter the collection box.

The rear section of the conveying belt is lifted upwards, the height of the collecting box is lower than that of the rear end of the conveying belt, and the inclination angle of the dewatering barrel and the horizontal plane is not more than 45 ℃.

The outer walls of the front end and the rear end of the dehydration barrel are provided with gear rings, a rotating shaft of the rotating motor is connected with a gear, the gear of the rotating motor is meshed with the gear rings, and the rotating motor drives the dehydration barrel to rotate.

In the sludge conveying process, a large amount of moisture in the sludge is discharged from filter holes of a conveying belt, meanwhile, the volatilization of the moisture can be increased by hot air blown by a conveying baffle plate, in a dewatering barrel, the sludge is taken to a high position and then freely falls by utilizing the rotation of the dewatering barrel, sludge impurities and the moisture are separated in the falling process, and when the sludge falls on the barrel wall below, a large amount of moisture still can be separated, the moisture can be discharged from the filter holes of the barrel wall, through the process, a large amount of moisture in the sludge can be discharged, and the volume and the weight of the sludge entering a collecting box are greatly reduced.

The utility model discloses a secretly contain desilting robot silt collection device, simple structure, the design science, convenient to use utilizes the moisture in conveyer belt filtration pore, hot-blast and three kinds of mode discharge silt of dehydration bucket, greatly reduced the volume and the quality of silt in the collection box, reduce and change the frequency, effectively improved the efficiency of desilting.
